Description

The crane beam is supported on a lattice column in most parts, and the lattice column comprises an upper column, a shoulder beam and a lower column which are sequentially connected from top to bottom. The existing steel structure crane beam generally adopts an I-shaped beam, and part of the beam adopts a box beam. When the crane beam is installed, two ends of the crane beam are simply supported, and the structure is that two ends of the crane beam are supported on the shoulder beam of the lattice column through the flange support or the flat support and then are fixedly connected with the shoulder beam through the support plate. When the two ends of the crane beam are in a simple support form, the section of the crane beam can also be called as a simple support beam, and the problem of connection between the crane beam and the lattice column is simpler to process.

However, because one end of the crane beam is required to be cantilevered far away in part of fields, even more than 10m, if the crane beam adopts a common i-shaped beam, the horizontal force resistance and torsion resistance of the crane beam cannot meet the requirement of a cantilever, a plurality of parts are required to be added, and the connection structure is complex. At present, for a structure that one end of a crane beam is far cantilevered, more box-type beams are adopted, and the crane beam structure with one cantilever structure is made, and at this time, the section of the crane beam is a continuous structure (namely, the crane beam is continuous at a corresponding support, and the support continuously passes through the support without being broken), and the section of the crane beam with the continuous structure can be called as a continuous box-type crane beam. However, in the prior art, the connection structure of the continuous box crane beam and the lattice column is complex, the construction difficulty is high, and the construction period is long.

Therefore, the inventor provides a connecting node structure of a continuous box crane beam and a lattice column by virtue of experience and practice of related industries for many years, so as to overcome the defects in the prior art.

Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 1 to 24, the present embodiment provides a connection node structure of a continuous box-type crane beam and a lattice column, including a continuous box-type crane beam 10 and a lattice column 20, where the continuous box-type crane beam 10 is a box-type beam structure enclosed by an upper flange plate 11, a lower flange plate 12, a first web 13 and a second web 14, and the lattice column 20 includes an upper column 21 and a shoulder beam 22 connected up and down. An upper through hole 111 and a lower through hole 121 are respectively formed on the upper flange plate 11 and the lower flange plate 12, and the upper end of the upper column 21 sequentially passes through the lower through hole 121 and the upper through hole 111. A support 3 is fixedly arranged at the bottom of the lower flange plate 12, the support 3 is supported on a shoulder beam 22, and a support plate 5 is fixedly arranged on the shoulder beam 22 and positioned at the side part of the support 3. The top of the upper column 21 is fixedly connected with the upper flange plate 11 through the upper fixing component 6, the upper fixing component 6 can cover the upper through hole 111, the bottom of the upper column 21 is fixedly connected with the lower flange plate 12 through the lower fixing component 7, and the supporting plate 5 is connected with the lower flange plate 12 through a plurality of first fastening pieces 51.

As shown in fig. 7 to 11, the lattice-type column 20 includes an upper column 21, a shoulder beam 22, and a lower column 23 connected in sequence from top to bottom, the upper column 21 and the lower column 23 are both vertically disposed, the shoulder beam 22 is horizontally disposed, and the specific structure is the existing structure. In order to ensure that the connection between the continuous box crane beam 10 and the lattice column 20 at the connection node does not affect the installation of the track 4 and to ensure structural stability, it is generally required that the track 4 is provided on one of the webs of the continuous box crane beam 10 and the upper column 21 is provided adjacent to the other web. In the embodiment, the rail 4 is arranged on the upper flange plate 11 and opposite to the second web plate 14, the length direction of the rail 4 extends along the length direction of the second web plate 14, and the upper column 21 is arranged close to the first web plate 13. The support 3 is preferably a flat plate support, and the length direction of the support 3 is perpendicular to the rail 4 (i.e. perpendicular to the second web 14), and mainly bears vertical force; the length direction of the supporting plate 5 is preferably perpendicular to the rail 4 for fixing the lower flange plate 12 with the shoulder beam 22 and mainly receiving horizontal forces in the direction of the rail 4.

In construction, the support 3 is welded to the bottom of the lower flange plate 12 in advance, and the support plate 5 is welded to the shoulder beam 22 in advance. When the continuous box crane girder 10 is installed, the lower through hole 121 faces the upper column 21, and the continuous box crane girder 10 is sleeved from the top of the upper column 21 downward to the top of the upper column 21 to be flush with the upper flange plate 11, and the support 3 is supported on the shoulder beam 22. An operator can enter the continuous box crane beam 10 through the upper through hole 111, the lower flange plate 12 is fixedly connected with the support plate 5 through a plurality of first fasteners 51, and then the lower flange plate 12 is fixed with the upper column 21 through the lower fixing component 7; after the installation of the interior of the continuous box crane beam 10 is completed and the operator comes out, the upper flange plate 11 and the upper column 21 are then fixed and the upper through hole 111 is blocked by the upper fixing assembly 6.

Therefore, in the connection node structure in the embodiment, the lattice column 20 is inserted into the continuous box-type crane beam 10, and the continuous box-type crane beam 10 can be fixed with the shoulder beam 22 and the upper column 21 of the lattice column 20 through the first fastener 51, the upper fixing assembly 6 and the lower fixing assembly 7, so that the construction is simple; meanwhile, an operator can enter the continuous box-type crane beam 10 through the upper through hole 111 to operate, and the continuous box-type crane beam 10 is more convenient to mount and position. The whole connecting node structure can meet the structural requirement, is reasonable in stress, is convenient to construct on site, reduces the construction difficulty and shortens the construction period.

In the specific implementation, when the upper column 21 of the lattice column 20 is made of different section steel types, the specific connection mode with the continuous box crane beam 10 is slightly different, and there are two main cases as follows:

(1) in the first case: the upper column 21 is deformed steel

As shown in fig. 1 to 14, the deformed steel includes an i-shaped steel composed of a first flange plate 211, a second flange plate 212, and a column web 213, and two sub-flange plates 214 symmetrically provided at both ends of the first flange plate 211. The upper and lower through-

holes

111 and 121 penetrate the edges of the upper and

lower flange plates

11 and 12 in a direction toward the first web 13 at positions corresponding to the upper columns 21. The first web 13 is provided with a break-off opening 131 communicated with the upper through hole 111 and the lower through hole 121, the upper column 21 passes through the break-off opening 131, and the first flange plate 211 and the first web 13 are located on the same plane. The side part of the upper column 21 is fixedly connected with the first web plate 13 through the side fixing component 8, the support 3 is arranged right opposite to the second web plate 14, and two support plates 5 are arranged on two sides of the support 3.

It will be appreciated that the column web 213 and the second flange plate 212 are located inboard of the first web 13. In this case, the upper column 21 needs to pass through the first web 13, so the first web 13 is cut off at the position of the upper column 21 to form the cut-off opening 131, and the upper flange plate 11 and the lower flange plate 12 outside the first web 13 are also cut off at the position of the upper column 21, so that the upper through hole 111 and the lower through hole 121 pass through one side edge of the upper flange plate 11 and the lower flange plate 12, respectively, at the position. In addition, since the first web 13 is disconnected at the position of the upper column 21, the second web 14 continuously passes through the support 3, and the first web 13 and the upper column 21 are fixed by the side fixing assembly 8 at the disconnection opening 131, the support 3 is only arranged below the second web 14, so that the stress requirement can be met.

More specifically, in this case, in order to facilitate the installation and fixation between the upper flange plate 11 and the upper column 21, as shown in fig. 1 and 3, the upper fixing assembly 6 includes an upper horizontal stiffening rib 61 fixed to the top of the upper column 21, a cover plate 62 provided on the upper flange plate 11 and capable of covering the upper through hole 111, two first connecting plates 63 provided on the upper flange plate 11 and located outside the first web 13, an upper connecting member 64 provided at the bottom of the upper flange plate 11 and fixed to the second flange plate 212, and a plurality of upper fixing members 68. The cover plate 62 is connected to the upper flange plate 11 and the upper horizontal stiffener 61 by a plurality of upper fasteners 68, both ends of the upper horizontal stiffener 61 located outside the first flange plate 211 are connected to the adjacent upper flange plate 11 by a corresponding first connecting plate 63 and a plurality of upper fasteners 68, respectively, and the upper connecting member 64 is connected to the upper flange plate 11 by a plurality of upper fasteners 68.

Wherein, the upper horizontal stiffening rib 61 can be welded on the top of the upper column 21 in advance, and the upper connecting piece 64 is preferably an angle steel, one of which is welded with the outer side of the second flange plate 212 in advance. When installed, the continuous box crane beam 10 is sleeved down from the top of the upper column 21 to the upper horizontal stiffener 61 flush with the upper flange plate 11. After the installation of the interior of the continuous box crane beam 10 is completed, the cover plate 62, the upper horizontal stiffening rib 61 and the upper flange plate 11, the first connecting plate 63, the upper horizontal stiffening rib 61 and the upper flange plate 11, and the other steel plate of the upper connecting piece 64 and the upper flange plate 11 are connected through a plurality of upper fasteners 68, so that the fixation of the upper flange plate 11 and the upper column 21 can be completed, and the construction is simple. Since the stress of the continuous box crane beam 10 is mainly concentrated on the upper flange plate 11 and near the position close to the rail 4, the horizontal force to be borne by the upper flange plate 11 is larger than that of the lower flange plate 12, and therefore, the top of the upper column 21, the upper flange plate 11 and each joint are fixed, and the stability of the continuous box crane beam can be ensured.

As shown in fig. 2, the general upper horizontal stiffener 61 includes two first upper horizontal stiffeners 611 symmetrically disposed at both sides of the column web 213 and a second upper horizontal stiffener 612 disposed outside the first flange plate 211, each of the first upper horizontal stiffeners 611 is connected to the cap plate 62 by a plurality of upper fasteners 68, and both ends of the second upper horizontal stiffener 612 are connected to the corresponding first connecting plates 63 by a plurality of upper fasteners 68, respectively.

Further, in order to facilitate the installation and fixation between the lower flange plate 12 and the upper column 21, as shown in fig. 3 and 6, the lower fixing assembly 7 includes a lower horizontal stiffening rib 71 fixed to the bottom of the upper column 21 and a plurality of lower fasteners 73, and the lower horizontal stiffening rib 71 is connected to the lower flange plate 12 by the plurality of lower fasteners 73.

Because the horizontal force that lower flange plate 12 needs to bear is less relatively, the position that lower flange plate 12 corresponds second web 14 has already been fixed with shoulder 22 through backup pad 5, and second flange 212 is close to second web 14 and sets up, so need not increase the adapting unit between second flange 212 and the lower flange plate 12 again and fix, also can satisfy the atress requirement. Because the aileron flange 214 is far away from the second web 14 below the rail 4, when the size of the outer part of the lower flange plate 12 on the first web 13 is small, the aileron flange 214 and the lower flange plate 12 are not fixed, and the stress requirement can be met. When the size of the lower flange plate 12 at the outer portion of the first web 13 is large, the fixing between the sub-flange plate 214 and the lower flange plate 12 is preferably performed to ensure the structural stability; at this time, the lower fixing assembly 7 further includes two second connecting plates 72 disposed at the bottom of the lower flange plate 12, each second connecting plate 72 is fixedly connected to the outer side of the corresponding sub-flange plate 214, and each second connecting plate 72 is connected to the adjacent lower flange plate 12 through a plurality of lower fastening members 73.

Wherein the second connecting plate 72 is horizontally disposed and welded to the outer side of the corresponding aileron flange 214 in advance, and the lower horizontal stiffening rib 71 can be disposed above the lower flange plate 12 and welded and fixed to the upper column 21 during the installation process. Specifically, during installation, after the lower flange plate 12 and the support plate 5 are fixedly connected through the plurality of first fasteners 51, the lower horizontal stiffening rib 71 is placed on the lower flange plate 12 and is welded and fixed with the upper column 21, and then the lower horizontal stiffening rib 71 and the lower flange plate 12 as well as the first connecting plate 63 and the lower flange plate 12 are fixedly connected through the plurality of lower fasteners 73, so that the lower flange plate 12 and the upper column 21 can be fixed, and the construction is simple. Of course, the lower horizontal stiffener 71 may be welded to the bottom of the upper column 21 in advance and installed below the lower flange plate 12 as needed, and the lower horizontal stiffener 71 may be directly fixed to the lower flange plate 12 by the lower fastening member 73 during installation.

As shown in fig. 6, the general lower horizontal stiffener 71 includes two sub-lower stiffeners 711 symmetrically fixed to both sides of the column web 213, and the two sub-lower stiffeners 711 are connected to the adjacent lower flange plates 12 by a plurality of lower fasteners 73, respectively.

Further, in order to facilitate the installation and fixation of the first web 13 between the position of the opening 131 and the upper column 21, as shown in fig. 5, the side fixing assembly 8 includes a side riser 81 fixed to the side of the upper column 21 and a plurality of side fasteners 82, and the side riser 81 is connected to the first web 13 on both sides of the opening 131 through the plurality of side fasteners 82.

Preferably, to improve the structural stability, as shown in fig. 6, the lateral risers 81 include two sets of sub-risers symmetrically affixed to the outer sides of the two aileron flanges 214, each set of sub-risers including an outer riser 811 and an inner riser 812 respectively located at the outer side and the inner side of the first web 13, and the outer riser 811, the inner riser 812 and the first web 13 are connected by a plurality of lateral fasteners 82.

Wherein the outer risers 811 may be pre-welded outboard of the corresponding aileron platform 214. After the lower flange plate 12 and the upper column 21 are fixed during installation, the inner vertical plate 812 and the outer side of the corresponding aileron flange plate 214 are welded and fixed, and then the outer vertical plate 811, the inner vertical plate 812 and the first web 13 on the corresponding side of the broken opening 131 are connected through the plurality of side fasteners 82, so that the fixation of the first web 13 and the upper column 21 can be completed, and the construction is simple.

(2) In the second case: the upper column 21 is I-shaped steel

As shown in fig. 15 to 24, the i-section steel includes a first flange plate 211, a second flange plate 212, and a column web 213, an upper portion of the upper column 21 is located inside the continuous box-type crane beam 10 and the first flange plate 211 is disposed adjacent to the first web 13. A support 3 is respectively arranged at the bottom of the lower flange plate 12 and opposite to the first web plate 13 and the second web plate 14, and two support plates 5 are arranged at two sides of each support 3.

It will be appreciated that in this case the upper column 21 passes directly inside the continuous box crane beam 10, the first and

second webs

13, 14 passing continuously at the respective abutments 3. Since this case is no longer the case where the side fixing component 8 can fix the first web 13 and the upper column 21, in order to ensure the structural stability, the second case needs to be provided with the support 3 and the support plate 5 at the positions corresponding to the first web 13 and the second web 14 to satisfy the stress requirement.

More specifically, in this case, in order to facilitate the installation and fixation between the upper flange plate 11 and the upper column 21, as shown in fig. 15 and 16, the upper fixing assembly 6 includes an upper horizontal stiffener 61 fixed to the top of the upper column 21, a cover plate 62 provided on the upper flange plate 11 and capable of covering the upper through-hole 111, a first connecting member 65 fixed to the outside of the first flange plate 211, a second connecting member 66 fixed to the outside of the second flange plate 212, and a plurality of upper fixing members 68. The deck plate 62 is connected to the upper flange plate 11 and the upper horizontal stiffener 61 by a plurality of upper fasteners 68, and a second connector 66 is provided at the bottom of the upper flange plate 11 and connected to the upper flange plate 11 by a plurality of upper fasteners 68. The first connecting member 65 is disposed at the bottom of the upper flange plate 11 and connected to the upper flange plate 11 through a plurality of upper fastening members 68, or a gap is formed between the first connecting member 65 and the upper flange plate 11, a third connecting plate 67 is further disposed on the upper flange plate 11, and the third connecting plate 67 is connected to the upper flange plate 11 and the first connecting member 65 through a plurality of upper fastening members 68.

Wherein, the upper horizontal stiffening rib 61 can be welded on the top of the upper column 21 in advance, and the first connecting piece 65 and the second connecting piece 66 are both preferably angle steel, one of which is welded with the outer side of the first flange plate 211 or the outer side of the second flange plate 212 in advance. When installed, the continuous box crane beam 10 is sleeved down from the top of the upper column 21 to the upper horizontal stiffener 61 flush with the upper flange plate 11. After the installation of the interior of the continuous box crane beam 10 is completed, the decking 62 is connected to both the upper horizontal stiffener 61 and the upper flange plate 11 and to the other steel plate of the second connector 66 and the upper flange plate 11 by a plurality of upper fasteners 68.

For the first connecting member 65, if the distance between the first flange plate 211 and the adjacent upper flange plate 11 is short, the other steel plate of the first connecting member 65 and the upper flange plate 11 can be directly connected through a plurality of upper fastening members 68; if the first flange plate 211 is spaced apart from the adjacent upper flange plate 11 as shown in fig. 16, the third connecting plate 67 may be connected to the upper flange plate 11 and the other steel plate of the first connecting member 65 by a plurality of upper fastening members 68 using the third connecting plate 67. Thus, the upper flange plate 11 and the upper column 21 can be fixed, and the construction is simple. Because the horizontal force that upper flange plate 11 needs to bear is bigger than the lower flange plate 12 atress, all fix the top of upper column 21 and upper flange plate 11 and each butt joint, can guarantee its steadiness more.

The upper horizontal stiffener 61 generally comprises two sub-upper stiffeners symmetrically attached to the two sides of the column web 213, both sub-upper stiffeners being connected to the cover plate 62.

Further, in order to facilitate the installation and fixation between the lower flange plate 12 and the upper column 21, as shown in fig. 16 and 19, the lower fixing assembly 7 includes a lower horizontal stiffening rib 71 fixed to the bottom of the upper column 21 and a plurality of lower fasteners 73, and the lower horizontal stiffening rib 71 is connected to the lower flange plate 12 by the plurality of lower fasteners 73.

Because the horizontal force that the lower flange plate 12 needs to bear is relatively small, and the positions of the lower flange plate 12 corresponding to the first web plate 13 and the second web plate 14 are fixed with the shoulder beam 22 through the corresponding supporting plates 5, the stress requirement can be met only by fixing the lower horizontal stiffening ribs 71 with the lower flange plate 12 in the second case.

When the installation is performed, the lower horizontal stiffening rib 71 may be disposed above the lower flange plate 12 and welded and fixed to the upper column 21 during the installation process, or the lower horizontal stiffening rib 71 may be disposed below the lower flange plate 12 as required and welded and fixed to the upper column 21 in advance, the installation process is similar to the first case, and details are not described herein.

As shown in fig. 19, the general lower horizontal stiffener 71, like the first case, includes two sub-lower stiffeners 711 symmetrically fixed to both sides of the column web 213, and the two sub-lower stiffeners 711 are connected to the adjacent lower flange plates 12 by a plurality of lower fasteners 73.

The first case is often adopted on site in the above-described first and second case structures. Of course, the upper column 21 of the lattice column 20 may be made of other types of section steel, and the corresponding upper fixing assembly 6 and lower fixing assembly 7 may be adjusted accordingly, as long as the continuous box crane beam 10 and the upper column 21 can be conveniently fixed together and meet the stress requirement, which is only illustrated in this embodiment.

Further, in the first and second cases, since the upper column 21 partitions the inside of the continuous box-type crane beam 10 during installation, in order to facilitate connection of the cover plates 62, as shown in fig. 1 and 15, the upper column 21 divides the upper through hole 111 into two mounting holes at both sides of the upper column 21, the cover plate 62 includes two sub-cover plates 621 symmetrically disposed at both sides of the upper column 21, and each sub-cover plate 621 is connected to the upper flange plate 11 and the upper horizontal stiffening rib 61 around the corresponding mounting hole by a plurality of upper fastening members 68.

The thickness of the cover plate 62 is generally the same as the thickness of the upper flange plate 11. It is understood that in the first case, as shown in fig. 1, two sub-sheathing panels 621 are connected to the corresponding first upper horizontal stiffeners 611, respectively; in the second case, as shown in fig. 15, two sub cover sheets 621 are connected to the corresponding sub upper stiffeners, respectively.

Further, as shown in fig. 1, 13, 15 and 23, in order to reinforce the side of the continuous box-type crane beam 10 having the rail 4, a reinforcing web 15 is provided between the second web 14 and the upper column 21 in the continuous box-type crane beam 10, and a plate surface of the reinforcing web 15 is parallel to the second web 14. More preferably, the continuous box crane beam 10 is provided with support stiffeners 16 at locations corresponding to the supports 3 below the second web 14, the support stiffeners 16 being perpendicular to the second web 14 and the inboard ends of the support stiffeners 16 extending between the upper column 21 and the reinforcing web 15.

It will be appreciated that the top and bottom of the reinforcing web 15 are connected to the upper and

lower flange plates

11 and 12 respectively. Since the inner side of the reinforcing web 15 is close to the second flange plate 212 of the upper column 21, the reinforcing web 15 will interfere with the upper connecting member 64 and the second connecting member 66, and therefore, the upper connecting member 64 and the second connecting member 66 will be disconnected at the position of the reinforcing web 15, and two sections of angle steel symmetrically arranged at both sides of the reinforcing web 15 are formed. The outer ends of the support stiffeners 16 are generally aligned with the outer edges of the upper flange plate 11, the number and connection mode of the support stiffeners 16 can be determined according to the strength requirement, and the support stiffeners 16 facing the support 3 need to be simultaneously aligned with the upper flange plate 11 and the lower flange plate 12; the carrier stiffeners 16 not facing the carrier 3 may be connected only to the upper flange plate 11, or may be connected to both the upper flange plate 11 and the lower flange plate 12. For example, in the present embodiment, three carrier stiffeners 16 are provided in parallel to each other, as shown in fig. 12 and 13, the carrier stiffener 16 located in the middle is disposed opposite to the carrier 3 at the bottom of the second web 14 and connected to both the upper flange plate 11 and the lower flange plate 12, and the two carrier stiffeners 16 on both sides may be connected only to the upper flange plate 11 and not to the lower flange plate 12, for increasing the structural strength.

Further, as shown in fig. 1, 12 to 15, and 23 and 24, the continuous box-type crane beam 10 further includes at least two adjacent bulkheads 17, and the upper column 21 is inserted between the two adjacent bulkheads 17. A lower connecting member 18 is fixedly connected to one side of each partition 17, and the lower connecting member 18 is connected to the lower flange plate 12 by a second fastening member 181. Since reinforcement is generally only required at a position near the upper column 21, the lower connecting members 18 are only required to be connected between the two partition plates 17 at both sides of the upper column 21 and the lower flange plate 12, so as to stabilize the lower flange plate 12 and improve the structural stability. In addition, the two ends of the reinforcing web 15 are connected to the two partitions 17, respectively, and the carrier stiffeners 16 are located in the region between the two partitions 17.

The lower connecting member 18 is preferably an angle steel, one steel plate of which is welded to the corresponding partition 17, and the other steel plate of which is connected to the lower flange plate 12 by a plurality of second fastening members 181. The lower connector 18 may be connected to the bulkhead 17 and the lower flange plate 12 during the manufacture of the continuous box crane beam 10.

It should be noted that, for the above-mentioned upper connecting member 64, first connecting member 65, second connecting member 66 and lower connecting member 18, all adopt welding fixation when connecting with the upper column 21 or the partition 17, all adopt corresponding fastener connection when connecting with the upper flange plate 11 or the lower flange plate 12, mainly because the continuous box crane beam 10 will have fatigue problem in the subsequent use, there will be a rocking phenomenon in the upper flange plate 11 and the lower flange plate 12, therefore, each connecting member and the upper flange plate 11 or the lower flange plate 12 do not adopt welding seam connection, but adopt fastener connection, can avoid the welding seam of the junction splitting when adopting welding, guarantee safe in utilization.

Generally to improve structural strength, as shown in fig. 13-15 and 23-24, a plurality of vertical stiffeners 19 are also provided on the outside and inside of the first and

second webs

13, 14, the vertical stiffeners 19 being perpendicular to the first web 13 and having their outside ends generally aligned with the outside edges of the upper flange plate 11. Each vertical stiffener 19 may be connected to only the upper flange plate 11, or may be connected to both the upper flange plate 11 and the lower flange plate 12, depending on the strength requirements.

Further, for the convenience of installation and positioning and the improvement of precision, as shown in fig. 4, 6 and 17 to 19, the continuous box-type crane beam 10 is formed by splicing at least two sectional crane beams 100, the upper flange plate 11 and the lower flange plate 12 of two adjacent sectional crane beams 100 are welded and fixed at the splicing position, and the first web plate 13 and the second web plate 14 of two adjacent sectional crane beams 100 are connected at the splicing position by the fourth connecting plate 101 and the plurality of third fasteners 102 in a matching manner.

It will be appreciated that each segmented crane beam 100 is a segment of a continuous box crane beam 10, as is the continuous box crane beam 10; there may be a set of splices near the location of the connection node, with the splice being located between one side of the upper column 21 and the adjacent bulkhead 17. Preferably, the splicing position P of the upper flange plates 11 of the two sectional crane beams 100₁The splicing position P of the lower flange plate 12₂Is offset from the splice location of the first and

second webs

13, 14. For example, in the orientation shown in fig. 4 and 17 in this embodiment, two sectional crane beams 100 are spliced at a left position of the upper column 21. During installation, after the lower flange plate 12 and the upper column 21 are fixed, the splicing operation of the sectional crane beam 100 can be performed. In the first case, the order of splicing the sectional crane beam 100 and fixing the first web 13 and the upper column 21 is optionally adjusted as required.

More preferably, the upper fastening member 68, the lower fastening member 73, the side fastening member 82, the first fastening member 51, the second fastening member 181, and the third fastening member 102 are all high-strength bolts, which can perform a reinforcing function, can further meet the stress requirement, and are convenient to construct.

In summary, in the connection node structure in this embodiment, the continuous box crane beam 10 and the lattice column 20 are connected by the high-strength bolt, and the joint connection portion not only can completely meet the structural requirement, but also is more reasonable in stress, convenient in site construction, and capable of saving the construction period compared with a common simple crane beam connection structure in the prior art.

The above are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention. Any person skilled in the art should also realize that such equivalent changes and modifications can be made without departing from the spirit and principles of the present invention.
