Description

Technical Field

[0001] This utility model relates to the field of construction, and in particular to an environmentally friendly prefabricated house column-beam connection structure. Background Technology

[0002] Prefabricated buildings refer to buildings assembled on-site using prefabricated components. The advantages of this type of building are fast construction speed, less susceptibility to weather conditions, labor saving, and improved building quality. In prefabricated buildings, the roof beam is one of the main supporting structures, which supports the safety, practicality, and aesthetics of the prefabricated building.

[0003] A search revealed that the patent with publication number CN211396007U specifically relates to a column-beam connection structure for an assembled house, including a first connecting plate, a second connecting plate, and fasteners. One side of the first connecting plate is welded to the column of the assembled house; one side of the second connecting plate is welded to the crossbeam of the assembled house; the other side of the second connecting plate and the other side of the first connecting plate are interlocked and tenoned, so that the first connecting plate supports the second connecting plate in the longitudinal direction; the fasteners tighten the first connecting plate and the second connecting plate in the transverse direction.

[0004] Existing equipment uses a beam convex plate and a column concave plate for support and interlocking to ensure the stability of the connection. However, the beam convex plate and column concave plate can only increase the support capacity of the connection, but cannot meet the requirements for longitudinal and lateral fixation of the connection. After the connection is installed, it cannot prevent the beam and column from shifting longitudinally or laterally, resulting in a loose connection.

[0005] Therefore, it is necessary to provide an environmentally friendly prefabricated house column-beam connection structure to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides an environmentally friendly prefabricated house column-beam connection structure.

[0007] This utility model provides an environmentally friendly prefabricated house column-beam connection structure, including prefabricated house columns. Two prefabricated house columns are symmetrically arranged. Prefabricated house beams are provided between the two prefabricated house columns through a support connection structure. The two prefabricated house columns are fixed to both sides of the prefabricated house beams through a clamping connection structure.

[0008] The clamping connection structure includes several sliding grooves symmetrically and equidistantly opened at the top of the two assembly room columns near each other. Each of the sliding grooves has a fixing bolt slidably installed inside. The front of each of the fixing bolts on the same side is inserted with the same clamping fixing plate. One end of each of the fixing bolts is threaded with a fixing nut. The assembly room beam is clamped between the four clamping fixing plates.

[0009] To reinforce the two clamping plates, this utility model provides an environmentally friendly prefabricated house column-beam connection structure. Preferably, two anti-displacement threaded rods are inserted between two clamping plates on the same side of the four clamping plates. The two anti-displacement threaded rods are externally located at both ends of the prefabricated house beam, and anti-displacement nuts are threaded onto both ends of the two anti-displacement threaded rods.

[0010] To facilitate the installation of fixing bolts, this utility model provides an environmentally friendly prefabricated house column-beam connection structure. Preferably, each of the several sliding grooves has a through hole at one end that is close to each other, and the diameter of each of the several through holes is larger than that of the several fixing bolts.

[0011] To achieve the supporting effect, this utility model provides an environmentally friendly prefabricated house column-beam connection structure. Preferably, the supporting connection structure includes a supporting fixing plate that is inclinedly fixed to the top of one end of two prefabricated house columns. The bottom ends of the two supporting fixing plates are connected to the corresponding prefabricated house columns through reinforcing plates. The same prefabricated house beam is placed on the top of the two supporting fixing plates.

[0012] In order to achieve the effect of fixing the support plate to the prefabricated house beam, this utility model provides an environmentally friendly prefabricated house column-beam connection structure. Preferably, the bottom ends of the two support plates are extended and installed in the locking screw holes at the bottom end of the prefabricated house beam by locking bolts.

[0013] In order to achieve the effect of installation and positioning, this utility model provides an environmentally friendly prefabricated house column-beam connection structure. Preferably, positioning blocks are fixedly installed at both ends of the bottom of the prefabricated house beam, and the bottom ends of the two positioning blocks are inserted into the grooves between the corresponding support fixing plates and the prefabricated house columns.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This environmentally friendly prefabricated house column-beam connection structure allows several fixing bolts to slide freely inside the groove, enabling two clamping fixing plates to jointly hold one end of the prefabricated house beam. This solves the problem of existing equipment using beam protrusion plates and column concave plates for support and clamping to ensure the stability of the connection. However, the beam protrusion plates and column concave plates can only increase the support capacity of the connection, but cannot meet the longitudinal and lateral fixing requirements of the connection. After the connection is installed, it cannot prevent the beam and column from shifting longitudinally and laterally, resulting in a loose connection. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of an environmentally friendly prefabricated house column-beam connection structure provided by this utility model; Figure 2 for Figure 1 The diagram shows the structural schematic of the assembled room columns; Figure 3 for Figure 1 The diagram shows the structural schematic of the clamping connection structure. Figure 4 for Figure 1 The diagram shows the structural schematic of the assembled beams. Figure 5 for Figure 2 The structural schematic diagram of part A shown includes assembly room columns 1. There are two symmetrically arranged assembly room columns 1. Assembly room beams 4 are provided between the two assembly room columns 1 through a support connection structure 2. The two assembly room columns 1 are fixed to both sides of the assembly room beams 4 through a clamping connection structure 3.

[0024] The clamping connection structure 3 includes several sliding grooves 301 symmetrically and equidistantly opened at the top of the two assembly room columns 1 close to each other. Each of the sliding grooves 301 has a fixing bolt 303 slidably installed inside. The front of each of the fixing bolts 303 on the same side is inserted with the same clamping fixing plate 304. One end of each fixing bolt 303 is threaded with a fixing nut 305. The assembly room beam 4 is clamped between the four clamping fixing plates 304.

[0025] It should be noted that: several fixing bolts 303 can slide arbitrarily in the corresponding slide grooves 301 until the two clamping fixing plates 304 are controlled to clamp one end of the assembled house beam 4. Then, the corresponding fixing nuts 305 are rotated to fix the two clamping fixing plates 304, so as to avoid the problem of misalignment and shaking of the assembled house beam 4.

[0026] In the specific implementation process, refer to Figure 3 and Figure 5 As shown, two anti-displacement threaded rods 306 are inserted through the two clamping and fixing plates 304 on the same side among the four clamping and fixing plates 304. The two anti-displacement threaded rods 306 are externally set at both ends of the assembly beam 4, and anti-displacement nuts 307 are threaded at both ends of the two anti-displacement threaded rods 306.

[0027] It should be noted that the two anti-displacement threaded rods 306 are externally set at both ends of the assembly beam 4, and the anti-displacement nuts 307 at both ends are rotated to reinforce the two clamping plates 304 to hold the two ends of the assembly beam 4, thus preventing the problem of falling off.

[0028] In the specific implementation process, refer to Figure 3 and Figure 5 As shown, each of the several sliding grooves 301 has a placement hole 302 at one end that is close to each other, and the diameter of the several placement holes 302 is larger than that of the several fixing bolts 303.

[0029] It should be noted that the diameter of several placement holes 302 is larger than that of several fixing bolts 303, which facilitates the placement of fixing bolts 303 and avoids the problem of fixing bolts 303 dislodging from slide grooves 301 when locking.

[0030] In the specific implementation process, refer to Figure 1 and Figure 5 As shown, the supporting connection structure 2 includes a supporting fixing plate 201 that is inclinedly fixed to the top of two prefabricated house columns 1 close to each other. The bottom ends of the two supporting fixing plates 201 are connected to the corresponding prefabricated house columns 1 through a reinforcing plate 203. The same prefabricated house beam 4 is placed on the top of the two supporting fixing plates 201.

[0031] It should be noted that the two supporting and fixing plates 201 support the assembled house beam 4, giving the assembled house beam 4 an upward force to prevent it from falling. The reinforcing plate 203, together with the assembled house column 1 and the supporting and fixing plate 201, forms a triangular reinforcement, increasing the load-bearing capacity of the two supporting and fixing plates 201 and preventing breakage.

[0032] In the specific implementation process, refer to Figure 4 and Figure 5 As shown, the bottom ends of the two supporting fixing plates 201 are extended and installed in the locking screw holes 5 at the bottom end of the assembly beam 4 by the locking bolts 202 provided.

[0033] It should be noted that the threaded connection between the locking bolt 202 and the locking screw hole 5 is achieved to avoid misalignment between the assembled beam 4 and the two supporting fixing plates 201.

[0034] In the specific implementation process, refer to Figure 1 and Figure 4 As shown, positioning blocks 6 are fixedly installed at both ends of the bottom of the prefabricated beam 4, and the bottom ends of the two positioning blocks 6 are inserted into the groove between the corresponding support fixing plate 201 and the prefabricated column 1.

[0035] It should be noted that positioning blocks 6 are fixedly installed at both ends of the bottom of the prefabricated beam 4 and snapped into the groove between the support plate 201 and the prefabricated column 1 to achieve preliminary positioning and avoid the problem of asymmetrical placement after installation.

[0036] The working principle of the environmentally friendly prefabricated house column-beam connection structure provided by this utility model is as follows:

[0037] In use, the two positioning blocks 6 at the bottom of the assembly beam 4 are placed inside the groove between the corresponding support fixing plate 201 and the assembly column 1, and the locking bolt 202 is rotated to connect with the locking screw hole 5 to fix the assembly beam 4. Several fixing bolts 303 slide arbitrarily in the corresponding sliding groove 301 until the two clamping fixing plates 304 clamp one end of the assembly beam 4. Then, the corresponding fixing nut 305 is rotated to fix the two clamping fixing plates 304, thus limiting the displacement of the assembly beam 4. Two anti-displacement threaded rods 306 are inserted through the corresponding two clamping fixing plates 304 and the assembly beam 4. Then, anti-displacement nuts 307 are threaded on both ends of the two anti-displacement threaded rods 306 to lock the two clamping fixing plates 304 and prevent the two clamping fixing plates 304 from bending.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
