Description
Technical field
The present invention relates to one kind building switching node structure and its construction method, and in particular to a kind of internal partition formula steel pipe is mixed
Solidifying soil switching node structure and its construction method.
Background technology
As the high-rise, function of high-rise building and form constantly develop toward diversified direction, the application of conversion layer
It is more and more extensive.Inclined column transfer structure has translation building block, and it is primarily subjected to xial feed, with Path of Force Transfer it is short, conversion structure
The less feature of part sectional dimension, is conducive to the use of space, thus is with a wide range of applications.In addition, because turning
Change component and be primarily subjected to xial feed, so being adapted to use concrete filled steel tubular member.Concrete filled steel tubular member size is than traditional steel
Reinforced concrete component is small, and saves template, is not required to assembling reinforcement, and construction speed is fast, construction quality is guaranteed.Inclined column transfer structure
Batter post and pillar when using concrete filled steel tubular member, referred to as concrete filled steel tube inclined column transfer structure.Node is mixed as steel pipe
The achievement in research of significant points in solidifying soil inclined column transfer structure, its mechanical property and building method is few, is mixed as restriction steel pipe
The bottleneck of solidifying soil inclined column transfer structure application.
According to the difference of translation building block type, existing inclined column transfer structure node is broadly divided into armored concrete inclined column transfer
Node, steel reinforced concrete Transferring Joints with Inclined Columns and concrete filled steel tube Transferring Joints with Inclined Columns three types.
1. translation building block is the Transferring Joints with Inclined Columns of reinforced concrete member
Batter post and pillar are reinforced concrete member, and batter post, pillar, the reinforcing bar of building roof beam are intersected at node, node
Area's concrete poured up at a time.Batter post, the internal force of building roof beam are transferred directly to node district, Ran Houchuan by reinforcing bar and concrete
It is handed to pillar, the good integrity of node.But, Shortcomings in actual applications, predominantly：
(1) sectional dimension of members is big, influences the use of space.Batter post in inclined column transfer structure undertakes superstructure
The load transmitted, internal force is larger, and bigger with the bigger batter post internal force in inclination angle of vertical direction.The bearing capacity of reinforced concrete member
Relatively low, in order to meet the requirement of security, the sectional dimension of batter post and the volume of node are larger, and transfer floor will be caused to build
The inconvenience that reduction and pipeline using space are passed through.
(2) node construction difficulty is big.Although the globality of Reinforced Concrete Transferring Joints with Inclined Columns is preferably, many batter posts,
Pillar, the reinforcing bar of building roof beam collect in node district, anchored, and node district reinforcing bar is intensive, colligation is difficult, and construction quality is difficult to ensure card.Section
Point area's volume is big, and casting and compacting of concrete density is difficult to ensure card, and heat of hydration height, temperature stress are larger when pouring, and fracture is controlled not
Profit.In addition, concrete structure construction process needs form erecting operation, the duration is longer.
2. translation building block is the Transferring Joints with Inclined Columns of Steel Reinforced Concrete Members
Batter post and pillar are Steel Reinforced Concrete Members, and batter post, pillar, the reinforcing bar of building roof beam, shaped steel are intersected at node,
Node district concrete poured up at a time.Batter post, the internal force of building roof beam are transferred directly to node by shaped steel, reinforcing bar and concrete
Area, is then passed to pillar, the good integrity of node.
The translation building block of this type node uses steel reinforced concrete, and section is smaller than reinforced concrete member, is conducive to building
The use in space.But, the reinforcing bar for having many batter posts, the shaped steel of pillar and reinforcing bar and building roof beam at node collects, node district
Reinforcing bar is intensive, colligation is difficult, and difficulty of construction is big, and quality is difficult to ensure card.
3. translation building block is the Transferring Joints with Inclined Columns of concrete filled steel tubular member
Batter post and pillar use concrete filled steel tube, and building roof beam typically uses girder steel or girder with rolled steel section en cased in concrete, beam and node
Connected mode it is identical with general Concrete-filled tubular connections.Vertical load is transmitted by the connection of batter post and pillar, and beam-ends is curved
Square is transmitted by node internal partition or outer annular-stiffer, and Shear force within the beam end is entered by the connection of web and pillar or batter post steel pipe
Row transmission.The concrete filled steel tube inclined column transfer structure applied in engineering mainly has following two types, respectively there is advantage and disadvantage：
(1) batter post mutually passes through formula node with pillar.Rectangle and circular cross-section concrete filled steel tube can be respectively adopted in batter post and pillar
Post, also can use circular cross-section steel core concrete column, and the requirement to member section shape is relatively low.Pillar side punches mouth, tiltedly
Post is mutually passed through with pillar and is connected from pillar side, and node district sets internal partition or outer ring plate, building roof beam be connected with pillar in node district or
Directly be connected with batter post, batter post, node, pillar concrete once or segmentation is poured and smashes completion.
Pillar side punches and weakens Post sections, and causes the stress distribution for mutually passing through region to complicate.Batter post internal force with
Based on axle power, from side transmission internal force to pillar when, level is produced to pillar to shearing component and pillar and batter post Xiang Guan circle
The vertical shearing component in face.Level is undertaken to shearing component by the internal partition of Post sections shear-carrying capacity or node district, vertically
Shearing component is undertaken by steel pipe seam with mutually passing through the anti-shear concrete intensity at interface, and Path of Force Transfer is clearer and more definite, but power transmission unit it is many,
Cause node district stress distribution complicated, easily form plane of weakness.The building roof beam being generally aligned in the same plane with batter post can only be with batter post
Connection, it is impossible to be directly connected with pillar, the indefinite of node region power transmission will be further resulted in.If node district is connected by outer ring plate
Different directions building roof beam is connect, will greatly increase node district scope, architectural appearance is influenceed and uses.
(2) batter post and pillar dock node.The type node is only applicable to batter post and pillar and uses square-section steel
The situation of pipe concrete column, and general only 2 batter posts of connection.Pillar cross-sectional area and two batter post intersection bottom cross sections are total
Area equation, batter post lower end and each side steel plate butt welding of pillar, batter post intersection is welded with vertical baffle, vertical baffle with
Welded on the inside of pillar steel pipe, node district sets internal partition or outer ring plate, and building roof beam is connected in node district with pillar, batter post, node, branch
The concrete of post is once or segmentation is poured and smashes completion.Batter post internal force is directly transmitted by the steel pipe and concrete of docking, building roof beam
Power transfer mode is identical with common steel tube concrete joint in beam-ends.
The type node guarantee integrality of pillar, Path of Force Transfer is simple, clearly.When but, using the connected mode,
Concrete filled steel rectangular tubes component can only be used, and rectangular steel pipe is poor to the effect of restraint of core concrete, economic benefit
It is relatively low.
