[0002] With the rapid development of prefabricated buildings in my country, more and more structural forms have emerged, and prefabricated steel structure systems have emerged as a new type of building structure system. H-shaped steel beams are commonly used components in steel structure systems. One use of H-shaped steel beams is to connect with walls. In order to ensure that the H-shaped steel beams can be formed in accordance with the wall surface of the wall, and considering the requirements for thermal insulation and sound insulation of the steel beams, the beam holes on both sides of the steel beams need to be filled. The current practice is to fill with hollow bricks and apply cement slurry on the surface of the outer hollow bricks. However, this filling method requires the laying of multiple hollow bricks, which has low construction efficiency; at the same time, it is impossible to ensure the precise matching of hollow bricks and steel beams, and it is easy to form gaps at the junction of hollow bricks and steel beams; in addition, the weight of hollow bricks is large, which can easily cause excessive deflection of steel beams. Summary of the invention

[0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. To this end, one object of the present invention is to provide a prefabricated beam socket filling structure, which can improve construction efficiency, reduce the gap between the filling material and the steel beam, and reduce the degree of deflection of the steel beam compared to the method of filling with hollow bricks.

[0006] The technical solution adopted by the present invention is:

[0007] In a first aspect, a prefabricated beam socket filling structure is provided, comprising a steel beam and an EPS component, wherein at least one side of the steel beam has a beam socket, and the beam socket is filled with an EPS component.

[0012] Furthermore, a fireproof layer covers the outer surface of the steel beam on the opening side.

[0013] Furthermore, mortar is filled between the inner wall of the beam cavity and the EPS component.

[0014] In a second aspect, a building structure is provided, including walls and floor slabs, and also including the above-mentioned assembled beam socket filling structure, wherein the steel beam is supported between the wall and the floor slab.

[0015] Furthermore, the steel beam is supported above the wall, and a flexible layer is filled between the steel beam and the wall, or a flexible layer is filled between the steel beam and the floor slab.

The terms used in the present invention are only for describing specific embodiments, not for limiting the present invention.

[0029] Reference Figure 1 , shows a cross-sectional view of a first embodiment of a beam socket filling structure of the present invention. As shown in the figure, the assembled beam socket filling structure includes a steel beam 1 and an EPS component 2.

[0030] The beam cavity referred to in this article refers to a cavity with at least one side open formed by the flange and web of the steel beam, and the same applies to the whole text. In this embodiment, the steel beam 1 is an H-shaped steel beam, and beam cavities 11 are arranged on both sides thereof. Since the beam cavity 11 will form a large depression, and for the consideration of thermal insulation and sound insulation at the steel beam 1, the beam cavity 11 needs to be filled.

[0031] The filler used in this embodiment is EPS component 2. EPS material (Expanded Polystyrene) has excellent thermal insulation and sound insulation capabilities, and its density is much lower than that of hollow bricks. Therefore, using EPS component 2 to fill the beam cavity can greatly reduce the deadweight of the filling material, thereby reducing the load on the steel beam 1 and reducing the downward deflection of the steel beam 1, thereby helping to reduce the wall cracking caused by the downward deflection of the steel beam. At the same time, compared to hard hollow bricks, EPS component 2 can be freely cut according to the shape and size of the beam cavity 11, so as to achieve precise matching between EPS component 2 and beam cavity 11 and reduce the gap between the filler and beam cavity 11. In addition, EPS component 2 can be used as an integral structure to replace multiple hollow bricks for filling, thereby eliminating the step of laying hollow bricks, helping to reduce construction workload and improve construction efficiency.

[0032] The EPS component 2 in this embodiment is made of EPS board.

[0033] In this embodiment, the EPS component 2 and the steel beam 1 are connected by mortar. Specifically, after the beam cavity 11 is cleaned, the bonding mortar 12 is applied to each inner wall of the beam cavity 11, and the connection and fixation of the EPS component 2 and the steel beam 1 can be achieved after the mortar is cured. The bonding mortar is distributed in a dotted manner, and after being squeezed by the EPS component 2, it is evenly filled between the inner wall of the beam cavity 11 and the EPS component 2. The dotted mortar coating method can reduce the workload of mortar application.

[0034] In addition to the first embodiment of the beam socket filling structure described above, the present invention also discloses other embodiments, including but not limited to:

[0035] Second embodiment

[0036] Reference Figure 2 , showing a cross-sectional view of the second embodiment of the beam socket filling structure of the present invention. As shown in the figure, this embodiment is an improved embodiment of the first embodiment of the beam socket filling structure. This embodiment is also provided with a gypsum board 3, which is located on one side of the steel beam 1 and simultaneously covers the flange 13 of the steel beam 1 and the outer surface of the EPS component 2 located on the opening side of the beam socket 11. The gypsum board 3 covers the EPS component 2 as a fireproof layer, which can isolate the EPS component 2 from external fire sources. At the same time, the gypsum board 3 extends to cover the outer surfaces of the flanges 13 on the upper and lower sides of the steel beam 1, so as to directly connect to the wall or floor board, which is more conducive to the flushness of the wall surface.

[0037] Third embodiment

[0038] This embodiment is an alternative embodiment of the second embodiment of the beam socket filling structure. In this embodiment, the gypsum board 3 is located on one side of the steel beam 1 and only covers the outer surface of the EPS component 2 on the opening side of the beam socket 11. The outer surface of the flange 13 on the opening side of the beam socket 11 is covered by other coating materials.

[0039] Fourth embodiment

[0040] This embodiment is an improved embodiment of the second embodiment of the beam groove filling structure. In this embodiment, the gypsum board 3 and the EPS component 2 are pre-fixed by bonding or other means to form a composite component. The advantage of filling with a composite component is that the EPS component 2 and the gypsum board 3 can be cut and processed in the same pre-process, and the filling can also be done as a whole, thereby further reducing the construction workload and improving the construction efficiency.

[0041] Fifth embodiment

[0042] This embodiment is an improved embodiment of the fourth embodiment of the beam socket filling structure. In this embodiment, in order to reduce the difficulty of transportation and storage, multiple composite components are provided to fill the beam socket 11 of the same steel beam 1. Since the board surface of the composite component is relatively large, there are only vertical joints when multiple composite components are spliced, and the number of joints is small, so the risk of cracking can be reduced. In addition, this embodiment also fills caulking paste, kraft paper and glass fiber mesh cloth between adjacent composite components. The specific filling method is: fill caulking paste, kraft paper, caulking paste, glass fiber mesh cloth and caulking paste in order from inside to outside, wherein the caulking paste is used to fill the gap, the kraft paper is used to make the filling surface smoother, and the glass fiber mesh cloth is used to bear the force generated by uneven displacement on both sides of the seam to prevent cracks.

[0043] Sixth embodiment

[0044] This embodiment is an alternative embodiment of the second embodiment of the beam socket filling structure. In this embodiment, the fireproof layer is replaced by a cement layer, that is, after the EPS component 2 is filled in the beam socket 11, a cement layer is coated on the outer surface of the flange 13 and the EPS component 2 on the opening side of the beam socket 11.

[0045] Reference Figure 3 , showing a cross-sectional view of the first embodiment of the building structure of the present invention. As shown in the figure, the building structure includes a wall 4, a floor slab 5 and a flexible layer 6 in addition to the beam socket filling structure in the second embodiment. The bottom end of the steel beam 1 is supported on the top of the wall 4 through the flexible layer 6, the top of the steel beam 1 supports the floor slab 5, and the outer surface of the gypsum board 3 is flush with the outer surface of the wall 4. The flexible layer 6 between the steel beam 1 and the wall 4 can be compressed and deformed to different degrees with different pressures, thereby reducing the assembly accuracy between the steel beam 1, the wall 4 and the floor slab 5, while allowing the steel beam 1, the wall 4 and the floor slab 5 to have a certain degree of deformation after assembly.

[0046] In this embodiment, the material of the flexible layer 6 is polyurethane.

[0047] In addition to the first embodiment of the building structure described above, the present invention also discloses other embodiments of the building structure, including but not limited to:

[0048] Second embodiment

[0049] This embodiment is an alternative embodiment of the first embodiment of the building structure. In this embodiment, the flexible layer 6 is located between the steel beam 1 and the floor slab 5 .

[0050] Third embodiment

[0051] This embodiment is an improved embodiment of the first embodiment of the building structure. In this embodiment, a flexible layer 6 is provided between the steel beam 1 and the wall 4 , and between the steel beam 1 and the floor slab 5 .

[0052] Fourth embodiment

[0053] This embodiment is an improved embodiment of the first embodiment of the building structure. In this embodiment, the gypsum board 3 and the EPS component 2 are pre-fixed by bonding or the like to form a composite component.

[0054] Reference Figure 4 , shows a flow chart of the construction method of forming a building structure according to the present invention, and the corresponding building structure is the building structure in the fourth embodiment described above. As shown in the figure, the construction method includes the following steps:

[0055] The composite component is subjected to pre-processing operations such as cutting according to the shape and size of the beam cavity 11 .

[0056] Then, bonding mortar is dotted on the inner wall of the beam cavity, the EPS component 2 of the composite component is pressed into the beam cavity 11, and the position is adjusted so that the outer surface of the gypsum board 3 is flush with the outer surface of the wall 4.

[0057] Then, fill the spaces between the composite components, between the composite components and the floor slab 5, and between the composite components and the steel beam 1 in order from inside to outside with caulking paste, kraft paper, caulking paste, glass fiber mesh cloth, and caulking paste.

[0058] Finally, mesh plastering is applied to the outer sides of the composite components and the walls as a whole.

[0059] The above is a specific description of the preferred implementation of the present invention, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
