Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a temporary support conversion beam structure for installing a steel structure. Background Art

[0002] Large-span steel structure is a widely used structural form. When constructing large-span steel structure, due to the limitations of the transportation and construction machinery and equipment for the transportation and lifting of steel components, some steel components need to be installed in sections and blocks, and temporary supports need to be set up. When setting up temporary supports, it is necessary not only to ensure that the bearing capacity of the temporary supports can meet the requirements, but also to ensure that the bearing capacity of the lower structure of the temporary supports can meet the requirements. If no effective measures are taken, the bearing capacity of the concrete beams and slabs in the lower concrete structure needs to be verified. If the verification fails, additional effective measures need to be taken, which is rather troublesome. Therefore, the inventors proposed a steel structure installation temporary support conversion beam structure to solve the above problems. Utility Model Content

[0003] In response to the above-mentioned technical problems existing in the prior art, a steel structure is provided for installing a temporary support conversion beam structure, which solves the rather troublesome problem that when setting up temporary support, if the bearing capacity verification of the concrete beam and slab in the lower concrete structure fails, additional effective measures need to be taken.

[0004] The purpose and effect of this utility model are achieved by the following specific technical means:

[0005] A steel structure installation temporary support transfer beam structure includes a temporary support assembly;

[0006] The temporary support assembly includes an adjustable steel pipe, an I-beam conversion beam and several support steel plates. The adjustable steel pipe is detachably connected to the upper flange of the I-beam conversion beam, and several support steel plates are welded to the lower flange of the I-beam conversion beam.

[0007] Furthermore, there are two I-beam transfer beams, which are distributed transversely and fixed together, and a plurality of support steel plates are respectively welded to the lower flanges of the two I-beam transfer beams.

[0008] Furthermore, a plurality of evenly distributed connecting steel plates are welded between the upper flanges and the lower flanges of the two I-beam conversion beams, and connecting seats are welded between both ends of the two I-beam conversion beams.

[0009] Furthermore, the adjustable steel pipe includes a steel round pipe and an inner steel pipe. The steel round pipe is detachably connected to the upper flanges of the two I-beam conversion beams, and the inner steel pipe is slidably connected inside the steel round pipe.

[0010] Furthermore, a mounting plate is integrally formed at the bottom of the steel circular tube, and the mounting plate is connected to the upper flanges of the two I-beam conversion beams by bolts.

[0011] Furthermore, a diagonal bracing steel is welded below one side of the steel circular tube, and the lower end of the diagonal bracing steel is bolted to one of the support steel plates. The steel circular tube, the diagonal bracing steel and the support steel plate form a triangle.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] Part of the weight load of the steel truss structure is transferred to the I-beam transfer beam through the adjustable steel pipe. The I-beam transfer beam directly transfers the temporary support component itself and the load it bears to the concrete structure column through the support steel plate, which can avoid the concrete beam and slab in the lower concrete structure from being stressed. Even if the concrete beam and slab verification does not meet the requirements, the steel truss structure can be assembled. With the ingenious design of the temporary support component and the temporary support component bearing the force on the concrete structure column, the concrete beam and slab can be effectively protected, reducing the hidden dangers of quality accidents.

DETAILED DESCRIPTION

[0020] See also Figure 1-5 , further illustrate the embodiments of the present utility model;

[0021] like Figure 1-3As shown, a temporary support transfer beam structure for installing a steel structure includes a temporary support assembly 2, which includes an adjustable steel pipe, an I-steel transfer beam 23, and a plurality of support steel plates 25. In order to facilitate the installation and removal of the adjustable steel pipe and the I-steel transfer beam 23, the adjustable steel pipe is designed to be detachably connected to the upper flange of the I-steel transfer beam 23, specifically by bolt connection. If the connection strength between the adjustable steel pipe and the I-steel transfer beam 23 is considered, welding can also be used, and a plurality of support steel plates 25 are welded to the lower flange of the I-steel transfer beam 23.

[0022] like Figure 1 As shown, the support conversion beam structure is used for temporary support during the installation of the steel structure 1. The lower concrete structure 3 includes a plurality of concrete structural columns 31 and a plurality of concrete beam slabs 32. The concrete beam slabs 32 are connected to two adjacent concrete structural columns 31. The steel structure 1 includes a steel truss structure 11 and a steel structural column 12. The steel structural column 12 is fixedly connected to the lower concrete structure 3. Before installing the steel truss structure 11, the temporary support assembly 2 is moved, and the support steel plate 25 at the bottom of the temporary support assembly 2 is placed on the top of the concrete structural column 31 (in practice, the concrete beam slab 32 does not completely cover the concrete structural column 11). During the assembly process of the steel truss structure 11, the lower steel member of the steel truss structure 11 needs to be temporarily fixed to the top of the adjustable steel pipe. The height of the steel pipe is adjusted according to the height of the steel truss structure 11. The adjustable steel pipe can adopt the existing telescopic steel pipe. The telescopic steel pipe can be limited in height by bolts or buckles. Part of the weight load of the steel truss structure 11 is transferred to the I-steel conversion beam 23 through the adjustable steel pipe. The I-steel conversion beam 23 directly transfers the temporary support component 2 itself and the load it bears to the concrete structure column 31 through the support steel plate 25, which can avoid the concrete beam slab 32 in the lower concrete structure 3 from being stressed. Even if the concrete beam slab 32 does not meet the requirements, the steel truss structure 11 can be assembled. With the ingenious design of the temporary support component 2 and the temporary support component 2 being stressed on the concrete structure column 31, the concrete beam slab 32 can be effectively protected, reducing the hidden dangers of quality accidents.

[0023] like Figure 5 As shown, there are two I-beam transfer beams 23, which are distributed laterally and fixed together, and can share the load transmitted downward by the adjustable steel pipe, thereby strengthening the load-bearing capacity of the supporting transfer beam structure. A number of support steel plates 25 are respectively welded to the lower flanges of the two I-beam transfer beams 23. The support steel plates 25 can directly transfer the load borne by the two I-beam transfer beams 23 to the concrete structure columns 31, thereby avoiding the concrete beam slab 32 in the lower concrete structure 3 from being subjected to stress. Even if the verification of the concrete beam slab 32 does not meet the requirements, the steel truss structure 11 can be assembled.

[0024] Specifically, several evenly distributed connecting steel plates 27 are welded between the upper flange and the lower flange of the two I-steel conversion beams 23, and connecting seats 28 are welded between the two ends of the two I-steel conversion beams 23. The use of several connecting steel plates 27 and two connecting seats 28 strengthens the connection strength of the two I-steel conversion beams 23.

[0025] The adjustable steel pipe includes a steel round pipe 21 and an inner steel pipe 22. The steel round pipe 21 is detachably connected to the upper flanges of two I-steel transfer beams 23. For example: Figure 4 In the figure, a mounting plate 26 is integrally formed at the bottom of the steel circular tube 21, and the mounting plate 26 is connected to the upper flanges of the two I-steel conversion beams 23 by bolts, so as to facilitate the connection between the steel circular tube 21 and the two I-steel conversion beams 23; the inner steel tube 22 is slidably connected to the steel circular tube 21, and a limiting structure is set between the inner steel tube 22 and the steel circular tube 21, such as a snap limit, a bolt and screw hole matching limit, etc.; when the adjustable steel tube is adjusted, the inner steel tube 22 can be moved upward or downward, and the inner steel tube 22 will slide in the steel circular tube 21. When the inner steel tube 22 is adjusted to the desired position, the limiting structure is used to limit it, and then the lower steel component of the steel truss structure 11 can be temporarily fixed to the top of the inner steel tube 22 with bolts to temporarily support the steel truss structure 11.

[0026] In addition, in order to strengthen the connection strength and stress stability between the steel circular tube 21, the I-beam conversion beam 23 and the support steel plate 25, a diagonal bracing steel 24 is welded below one side of the steel circular tube 21, and the lower end of the diagonal bracing steel 24 is bolted to one of the support steel plates 25. The steel circular tube 21, the diagonal bracing steel 24 and the support steel plate 25 form a triangle.
