Detailed Description
In order that those skilled in the art will better understand the technical solutions of the present utility model, the following description will clearly and completely describe the technical solutions of the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments of the present utility model.
Referring to fig. 1 or 3, a recoverable temporary support structure for steel studs on a concrete frame beam comprises a frame beam 1, a detachable support column 2 standing on the ground 10 is arranged at the lower part of the frame beam 1, a reserved steel stud 4 is connected to the upper part of the detachable support column 2 through a flange structure 3, the flange structure 3 comprises a lower flange 31 positioned at the lower part outside the frame beam 1, an upper flange 32 positioned in the frame beam 1 and a vertical rib plate 33 positioned between the upper flange 32 and the lower flange 31, and a plurality of accommodating cavities 5 are formed by the vertical rib plate 33 and the upper flange 32 in the frame beam 1.
In the above embodiment, the lower part of the frame beam 1 is provided with the detachable support column 2 standing on the ground 10, the upper part of the detachable support column 2 is connected with the reserved steel column head 4 through the flange structure 3, and the reserved steel column head 4 is supported by the support column 2 standing on the ground 10, so that after the construction of the beam slab with the first-layer structure is completed, the construction of the two-layer steel column and the whole structure is realized through the reserved steel column head 4; the flange structure 3 realizes the stable connection of the reserved steel column head 4 and the detachable support column 2 on one hand, and ensures that the steel bars 9 under the beam can be successfully inserted on the other hand, so that the integral structure of the frame beam 1 is not influenced; in addition, through setting up detachable support column 2 and flange structure 3, after the first floor roof beam is pour and is accomplished, detachable support column 2 and flange structure 3's lower ring flange 31 can retrieve reuse, improves the utilization ratio of device, has practiced thrift construction cost.
It should be noted that, in order to meet the first-layer design of different heights, the heights of the support columns 2 can be combined and spliced according to the difference of the first-layer heights, so as to realize the adjustment of the total height.
As shown in fig. 4, the height of the above-mentioned insertion accommodating chambers 5 for the under-beam reinforcing bars 9 can be adjusted according to actual construction needs, i.e., the height of the accommodating chambers 5 is adjusted by adjusting the height of the vertical ribs 33, and the number of the accommodating chambers 5 is adjusted by the number of the vertical ribs 33. The vertical ribs 33 serve to support the upper and lower flanges 31, and the increase in the number of the vertical ribs 33 can also improve the strength of the flange structure 3 as a whole to some extent. Of course, in order to facilitate the fixing of the vertical rib 33, the lower portion of the upper flange plate 32 is provided with a mounting groove (not shown in the drawings), and the vertical rib 33 can be more conveniently fixed at the lower portion of the upper flange plate 32 through the mounting groove, so that improper placement is avoided, the vertical rib 33 is inclined, and the stability and the firmness of the integral flange structure 3 are affected.
As shown in fig. 2, the upper flange 32 and the lower flange 31 are fixed by a plurality of split bolts 34. The split bolts 34 can fix the upper flange 32, the lower flange 31, and the vertical rib 33 provided therebetween, thereby forming the stable flange structure 3 for the subsequent construction. The number of split bolts 34 may be determined according to the length of the flange structure 3 as a whole.
In order to improve the overall structural strength of the support system, a first reinforcing rib 6 and a second reinforcing rib 7 are respectively arranged between the lower peripheral side of the reserved steel column head 4 and the upper flange plate 32 and between the lower peripheral side of the support column 2 and the temporary foundation 8. In actual construction, the number of the first reinforcing ribs 6 and the second reinforcing ribs 7 is specifically determined according to the specifications of the support column 2 and the reserved steel column head 4. In this embodiment, the angles between the adjacent first reinforcing ribs 6 and second reinforcing ribs 7 are 45 degrees, that is, 8 first reinforcing ribs 6 and second reinforcing ribs 7 are disposed along the circumferential directions of the support column 2 and the reserved steel column head 4.
Since the support columns 2 need to bear large pressure, the ordinary ground 10 may not be enough to provide enough supporting force, even the ground 10 may be depressed, and in order to avoid the situation, a temporary foundation 8 is usually required to be built between the lower part of the support columns 2 and the ground 10 in construction, so as to improve the overall bearing capacity of the ground 10.
According to the utility model, the detachable support column 2 which is vertical to the ground 10 is arranged at the lower part of the frame beam 1, the reserved steel column head 4 is connected to the upper part of the detachable support column 2 through the flange structure 3, and the reserved steel column head 4 is supported by the support column 2 which is vertical to the ground 10, so that the problem that after the construction of a beam slab with a first layer structure is finished, two layers of steel columns cannot adopt an automobile crane or a crawler crane and a first layer beam template cannot support the steel column head on the beam is solved.
While the foregoing is directed to embodiments of the present utility model, it will be appreciated by those skilled in the art that various modifications and changes can be made without departing from the principles of the present utility model, and such modifications and changes should be considered as being within the scope of the present utility model.
