Description

Technical Field

[0001] The present application relates to the technical field of building components, and in particular to a connection structure that facilitates the installation of drop-plate steel beams. Background Art

[0002] Lowering the floor means "lowering the structural elevation of the floor or roof panel (board surface)". Different rooms in the building have different functions, and different floor decoration materials are used accordingly, including stone, floor tiles, wooden floors, terrazzo, fine stone concrete, cement, etc. The construction methods of various materials are different, and the thickness is also different. Among them, the thickness of the slope waterproofing method is the largest, such as toilets, bathrooms, kitchens, etc., which makes the floor height difference of rooms with different materials. When the height difference is less than 30 mm, the thickness of the method can be adjusted with a cushion layer. If the height difference is greater than 30 mm, the "lowering the floor" method is used to reduce the floor elevation on the side with the larger method thickness, so that the floors of different methods are basically level after completion, avoiding too many small steps and small slopes to form obstacles and bring inconvenience to users.

[0003] Related technologies such as Figure 1 A steel beam shown in the figure comprises a beam body 1, a connecting plate 2 and connecting bolts 3. The beam body 1 comprises a web 10, and a wing plate 11 is vertically fixed to the upper and lower sides of the web 10 respectively. A main supporting plate 12 for supporting a drop-down floor is also fixed to the web 10, and the main supporting plate 12 is located between the upper and lower wing plates 11. A plurality of reinforcing plates 13 are fixed between the main supporting plate 12 and the wing plate 11 located below. The connecting plate 2 connects the webs 10 of two adjacent beam bodies 1 through a plurality of connecting bolts 3, and the connecting bolts 3 comprise screws 30 and nuts 31.

[0004] The above technology is used for the installation of a horizontal steel beam and another corbel steel beam. The drop-down floor is located below the area between the main supporting plates 12 of the two adjacent beam bodies 1 and will be suspended. Therefore, it is necessary to weld a supporting plate at the position of the suspended part of the drop-down floor. Therefore, most of the installation processes in the related technology are connecting the horizontal steel beam and the corbel steel beam - installing the drop-down floor - welding a supporting plate. Especially after the drop-down floor is installed, the welding operation is extremely troublesome. Utility Model Content

DETAILED DESCRIPTION

[0028] The following is combined with Figure 2 -Attached Figure 5 This application is described in further detail.

[0029] An embodiment of the present application discloses a connection structure that facilitates the installation of a drop plate steel beam.

[0030] Example 1

[0031] Reference Figure 2 and Figure 3A connection structure for facilitating the installation of a drop-down steel beam acts between a horizontal steel beam and a corbel steel beam, and the connection structure comprises a connection plate 2, a connection bolt 3 and a secondary support member 4 installed between two beam bodies 1. The beam body 1 comprises a web 10, and a wing plate 11 is vertically fixed to the upper and lower sides of the web 10, respectively. A main support plate 12 for supporting a drop-down floor is also fixed to the web 10, and the main support plate 12 is located between the upper and lower wing plates 11, and a plurality of reinforcing plates 13 are fixed between the main support plate 12 and the wing plate 11 located below.

[0032] Reference Figure 2 and Figure 3 The connecting plate 2 is arranged between two adjacent webs 10, and the connecting bolts 3 are connected between the webs 10 and the connecting plate 2. The connecting bolts 3 include screws 30 that pass through the webs 10 and the connecting plate 2, wherein a portion of the screws 30 is longer and another portion of the screws 30 is shorter. A nut 31 is threadedly connected to the end of the screw 30, and a gasket 32 ​​for cooperating with the nut 31 is sleeved on the screw 30.

[0033] Reference Figure 2 and Figure 3 The secondary supporting member 4 includes a supporting plate 40 vertically attached to the outer wall of the connecting plate 2, and a secondary supporting plate 41 is vertically fixed to the top of the supporting plate 40 for cooperating with the main supporting plate 12 to support the drop-down floor. According to actual conditions, a clearance gap 410 can be set at the position of the secondary supporting plate 41 corresponding to the connecting plate 2 to accommodate the connecting plate 2.

[0034] Reference Figure 3 and Figure 4 Two waist-shaped mounting holes 400 are vertically provided on the support plate 40, and a clearance groove 401 is provided on one side of the support plate 40 close to the connecting plate 2 and corresponding to the mounting holes 400, wherein the longer screw 30 is passed through the mounting holes 400 and fixed to the support plate 40 by the nut 31 and the washer 32, and the nut 31 and the washer 32 on the shorter screw 30 are located in the clearance groove 401. The clearance groove 401 can be used to accommodate part of the nut 31 and the washer 32, so that the support plate 40 and the connecting plate 2 are tightly fitted.

[0035] The implementation principle of Example 1 is as follows: after the construction personnel connect the two beam bodies 1, they first use part of the connecting bolts 3 to fix the connecting plate 2 on the beam body 1, and then install the secondary supporting member 4 when placing the drop-down floor, and adjust the height of the secondary supporting plate 41 through the waist-shaped installation hole 400, so that the secondary supporting plate 41 abuts against the drop-down floor, thereby supporting the drop-down floor, and then use another part of the connecting bolts 3 to fix the secondary supporting member 4. The overall construction process is relatively simple and convenient to operate, without complicated welding operations, which can effectively reduce the workload of construction personnel and improve construction efficiency.

[0036] Example 2

[0037] Reference Figure 5 The difference between this embodiment and embodiment 1 is that, in order to improve the stability of the relative position between the gasket 32 ​​and the support plate 40, thereby improving the stability of the secondary supporting plate 41 when supporting the drop-down floor, in this embodiment, a plurality of rows of ridges 320 are arranged on the side of the gasket 32 ​​facing the support plate 40, the gasket 32 ​​is in the shape of a rectangular plate, and the length direction of the ridges 320 is the same as the length direction of the web 10.

[0038] The implementation principle of the second embodiment is as follows: the construction personnel can tighten the nut 31 as much as possible, so that the ridge 320 is stuck into the surface of the support plate 40, providing a greater friction force, so that the secondary support member 4 is more stable.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
