Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to a light steel floor structure of an assembled building. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and uses rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing.

[0003] The existing prefabricated light steel floor structure still has some problems in the assembly structure setting. For example, the light steel floor structure of a prefabricated building proposed in the document with application number CN202122758855.9 has multiple groups of assembly connection structures, and most of them are connected with bolts. Such a structural setting makes the on-site assembly operation cumbersome, resulting in a long assembly time, time-consuming and labor-intensive. In view of this, we propose a light steel floor structure for prefabricated buildings. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a light steel floor structure for prefabricated buildings to solve the technical problems that the current assembly connection structures are numerous, resulting in cumbersome assembly operations, a waste of time, and time-consuming and laborious assembly operations.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: design a light steel floor structure of an assembled building, including a plurality of support columns, the upper ends of the plurality of support columns are fixed with connecting components, and beams are connected and installed between the connecting components on both sides;

[0006] The connecting component is provided with two connecting ends, and the angle between the two connecting ends is a right angle. The end face of the connecting end of the connecting component is a first inclined portion. The two connecting ends of the connecting component are provided with oblique card slots from top to bottom, and a strip groove is provided between the first inclined portion and the oblique card slot. The end faces of both ends of the beam are second inclined portions. Both ends of the beam are fixed with connecting plates combined with the strip groove, and the other end of the connecting plate is fixed with a clamping plate combined with the oblique card slot.

[0007] Preferably, two limiting assemblies are fixedly provided on the bottom side of the crossbeam, and limiting blocks combined with the limiting assemblies are fixedly provided on the side walls of the support column.

[0008] Preferably, the limiting assembly includes an elastic folding plate, the middle position of the elastic folding plate is an arc-shaped surface, the two ends of the middle position are parallel surfaces, a tension piece is fixed between the two end parallel surfaces of the elastic folding plate, the shape of the tension piece is a multi-segment wave shape, and a connecting block is fixed on the upper surface of the side end of the elastic folding plate close to the support column.

[0009] Preferably, a connection slot corresponding to the connection block is provided on the lower side of the limit block, and the four side surfaces of the connection slot and the connection block are all inclined surfaces.

[0010] Preferably, a bottom plate is fixedly provided at the bottom end of the support column, and a plate wall of the bottom plate is provided with through holes, and the number of the through holes is four.

[0011] Preferably, a support plate is fixedly provided on the outer wall of the support column, and the support plate is in contact with the bottom side of the crossbeam, and a reinforcing inclined plate is fixedly provided between the outer wall of the support column and the bottom surface of the support plate.

[0012] Preferably, the second inclined portions at both ends of the crossbeam are fitted and connected to the first inclined portions at both ends of the connecting assembly.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model facilitates limiting the installation position of the crossbeam by means of a connecting assembly arranged on the support column. The first inclined portion, the oblique insertion slot and the strip slot arranged on the limiting assembly cooperate with the second oblique portion, the connecting plate and the clamping plate on the crossbeam to quickly limit the crossbeam. At the same time, the oblique insertion at both ends can ensure that the position of the crossbeam is fixed after the position of the support column is fixed, thereby achieving the effect of fixed assembly. Through such structural cooperation, the assembly connection structure can be reduced, and the bolt fixing connection position can be omitted, so that the assembly operation is simple, the time required for assembly is reduced, and time and labor are saved.

[0015] 2. The cooperation between the limit assembly and the limit block in the utility model can strengthen the connection effect between the crossbeam and the support column. In this way, when disassembling, the limit assembly and the limit block need to be separated before the operation can be carried out, thereby strengthening the limit effect of the assembly. At the same time, the elastic folding plate on the limit structure can enhance the tensile strength with the cooperation of the tension member, and can automatically reset after the tensile deformation, thereby ensuring the tightness of the connection block and the connection slot. At the same time, it is also convenient for separation operation and simple to cooperate. BRIEF DESCRIPTION OF THE DRAWINGS

The first inclined portion 201 has the same inclination angle as the oblique insertion slot 202, so that the clamping plate 303 on the beam 3 can only be inserted obliquely into the oblique insertion slot 202, thereby limiting the installation method of the beam 3. At the same time, the other end of the beam 3 can only be combined with the oblique insertion slot 202 and the clamping plate 303 by tilting the support column 1. In this way, when the position of the support column 1 is fixed, the connection position of the beam 3 can be fixed, reducing the assembly connection structure, and reducing the assembly time while ensuring the connection strength.

[0025] Specifically, two limit assemblies 4 are fixedly provided on the bottom side of the beam 3, and a limit block 5 combined with the limit assemblies 4 is fixedly provided on the side wall of the support column 1; the combination of the limit assemblies 4 and the limit blocks 5 can enhance the connection effect between the support column 1 and the beam 3.

[0026] Furthermore, the limiting component 4 includes an elastic folding plate 401, the middle position of the elastic folding plate 401 is an arc-shaped surface, and the two ends of the middle position are parallel surfaces. A tension piece 402 is fixedly provided between the parallel surfaces at the two ends of the elastic folding plate 401, and the shape of the tension piece 402 is a multi-segment wave shape. A connecting block 403 is fixedly provided on the upper surface of the side end of the elastic folding plate 401 close to the support column 1; the overall bending effect can be ensured by setting the arc-shaped surface, and the parallel surfaces at both ends are conveniently connected to the support column 1 and the crossbeam 3. The multi-segment wave-shaped setting of the tension piece 402 can enhance the tensile strength of the elastic folding plate 401, so that it can automatically reset after losing the tension when folded, and the support strength can be ensured.

[0027] Furthermore, a connecting slot 501 corresponding to the connecting block 403 is provided on the lower side surface of the limit block 5, and the four side surfaces of the connecting slot 501 and the connecting block 403 are all inclined surfaces; by setting the inclined surfaces on the four sides, the upper surface of the connecting block 403 is smaller than the lower surface, which makes it convenient for the connecting block 403 to be inserted into the connecting slot 501.

The end is connected to another support column 1, and the support column 1 can be moved obliquely from bottom to top so that the oblique insertion slot 202 is combined with the clamping plate 303, so as to fix the positions of the two ends of the beam 3. In this way, the assembly operation of the support column 1 and the beam 3 can be completed, reducing the use of assembly components and effectively reducing the assembly time. Then, the support column 1 is fixed to the ground to ensure the limiting strength of the beam 3, which is not easy to loosen.
