[0003] For double-row precast concrete buildings, after the precast concrete modules are used to build the precast concrete buildings, the two rows of precast concrete buildings are set up facing each other. It is necessary to connect the cantilever of the two rows of precast concrete buildings to enhance the integrity of the two rows of precast concrete buildings. The existing connection method is complex in structure and inconvenient to operate. Utility Model Content

[0004] This utility model provides a concrete cantilever horizontal connection component, which aims to solve the problem of complex structure in the existing concrete cantilever connection method mentioned above.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A horizontal connection assembly for concrete cantilever includes a first connecting plate, a threaded sleeve, and a bolt. The threaded sleeve is pre-embedded in both concrete cantilevers to be connected. The first connecting plate has two first through holes. The bolt can pass through the first through holes and be threadedly connected to the corresponding threaded sleeve. The first connecting plate is clamped and fixed between the bolt and the threaded sleeve.

[0006] As a further improvement to the above technical solution: Preferably, the threaded sleeve includes a sleeve body and a reinforcing rod, the reinforcing rod being disposed on the outer side wall of the sleeve body, and the axial direction of the reinforcing rod being perpendicular to the axial direction of the sleeve body.

[0007] Preferably, there are multiple reinforcing rods, and each reinforcing rod is spaced apart circumferentially along the sleeve body.

[0010] Preferably, a reinforcing ring is fitted and fixed to the outer side of the sleeve body near the top outer side, and the reinforcing ring is coaxial with the sleeve body.

[0011] Preferably, the reinforcing ring is integrally formed with the sleeve body.

[0012] On the other hand, the concrete cantilever horizontal connection assembly also includes a second connecting plate, which has two second through holes.

Detailed Implementation

[0016] The embodiments will be further described below with reference to the accompanying drawings.

[0017] like Figures 1-3As shown, an embodiment of the present invention provides a concrete cantilever horizontal connection component 100. The concrete cantilever horizontal connection component 100 includes a first connecting plate 110, a threaded sleeve 120, and a bolt 130. The two concrete cantilevers to be connected are pre-embedded with threaded sleeves 120. The first connecting plate 110 has two first through holes. The bolt 130 can pass through the first through holes and be threadedly connected to the corresponding threaded sleeve 120. The first connecting plate 110 is clamped and fixed between the bolt 130 and the threaded sleeve 120.

[0018] When it is necessary to construct two rows of precast concrete buildings facing each other, such as Figure 3 As shown, firstly, threaded sleeves 120 are pre-embedded in the cantilever of the precast concrete structure. Then, two rows of precast concrete structures facing each other are erected. Finally, the bolt 130 passes through the first through hole and is threadedly connected to the corresponding threaded sleeve 120. The nut of the bolt 130 presses and fixes the first connecting plate 110 to the threaded sleeve 120. The first connecting plate 110 connects the cantilever of the two rows of precast concrete structures facing each other, thereby strengthening the overall integrity of the two rows of precast concrete structures. This concrete cantilever horizontal connection assembly 100 has the advantages of simple structure and easy operation.

[0019] In this embodiment, the first connecting plate 110 is made of connecting steel plate, which has high strength and can provide sufficient tension for the cantilever of the two rows of precast concrete buildings facing each other. Of course, it is understood that the first connecting plate 110 can also be made of other materials, as long as it can provide sufficient tension for the cantilever of the two rows of precast concrete buildings facing each other, and there is no limitation here.

[0020] One embodiment of this utility model provides a concrete cantilever horizontal connection component 100, such as... Figure 1 and Figure 2 As shown, the threaded sleeve 120 includes a sleeve body 121 and a reinforcing rod 122. The reinforcing rod 122 is disposed on the outer side wall of the sleeve body 121, and the axial direction of the reinforcing rod 122 is perpendicular to the axial direction of the sleeve body 121. The bolt 130 can pass through the first through hole and be threadedly connected to the corresponding sleeve body 121. The reinforcing rod 122, disposed on the outer side wall of the sleeve body 121, can strengthen the connection strength between the threaded sleeve 120 and the cantilever of the precast concrete building, that is, strengthen the installation strength of the threaded sleeve 120 on the cantilever of the precast concrete building.

[0021] Since the axial direction of the reinforcing rod 122 is perpendicular to the axial direction of the sleeve body 121, and when the bolt 130 is threadedly connected to the sleeve body 121, the force exerted on the sleeve body 121 is along the axial direction of the sleeve body 121. Since the axial direction of the reinforcing rod 122 is perpendicular to the axial direction of the sleeve body 121, the cantilever of the precast concrete building can provide a sufficiently large force on the reinforcing rod 122 along the axial direction of the sleeve body 121, so as to prevent the sleeve body 121 from detaching from the cantilever of the precast concrete building.

[0022] In this embodiment, as Figure 1 and Figure 2 As shown, there are multiple reinforcing rods 122, and each reinforcing rod 122 is spaced apart circumferentially along the sleeve body 121. Multiple reinforcing rods 122 are provided on the outer wall of the sleeve body 121, and these multiple reinforcing rods 122 can simultaneously provide a force along the axial direction of the sleeve body 121. The circumferential spacing of the reinforcing rods 122 ensures that the application points of the reinforcing rods 122 differ from those of the cantilever in precast concrete structures, and is more conducive to balancing the forces acting on the sleeve body 121.

[0023] In this embodiment, preferably, the reinforcing rod 122 can be integrally formed with the sleeve body 121 to ensure stability during use and make it more suitable for rapid on-site use.

[0024] One embodiment of this utility model provides a concrete cantilever horizontal connection component 100, such as... Figure 1 As shown, the outer side of the sleeve body 121 is flared with a lower diameter larger than the upper diameter, and the bolt 130 is threaded from the upper diameter side. This structure is mainly suitable for installation on top of concrete. By increasing the contact area and stress between the concrete and the sleeve, the strength and stability of the connection are improved. The concrete has a reaction force on the sleeve body 121, preventing the sleeve body 121 from coming off.

[0025] One embodiment of this utility model provides a concrete cantilever horizontal connection component 100, such as... Figure 1 As shown, a reinforcing ring 123 is fitted and fixed to the outer side of the sleeve body 121 near the top, and the reinforcing ring 123 is coaxial with the sleeve body 121. This increases the contact area and stress between the concrete and the sleeve, thereby improving the strength and stability of the connection. The concrete also has a limiting effect on the reinforcing ring 123, preventing the sleeve body 121 from coming off.

[0026] In this embodiment, preferably, the reinforcing ring 123 is integrally formed with the sleeve body 121 to ensure stability during use and to make it more suitable for rapid on-site use.

[0027] The present invention provides a concrete cantilever horizontal connection assembly 100, which further includes a second connecting plate with two second through holes. The threaded sleeve 120 is a bidirectional threaded sleeve 120 that penetrates the upper and lower surfaces of the concrete cantilever. A first connecting plate 110 is connected to one end of the bidirectional threaded sleeve 120, and a second connecting plate is connected to the other end of the bidirectional threaded sleeve 120.

[0028] When constructing two rows of precast concrete structures facing each other, threaded sleeves 120 are first embedded in the cantilever of the precast concrete structures. Then, the two rows of precast concrete structures are constructed. Finally, bolts 130 pass through the first through hole and are threaded to one end of the corresponding threaded sleeve 120. A first connecting plate 110 connects the cantilever of the two rows of facing precast concrete structures. Bolts 130 pass through the second through hole and are threaded to the other end of the corresponding threaded sleeve 120. A second connecting plate connects the cantilever of the two rows of facing precast concrete structures. The first connecting plate 110 and the second connecting plate simultaneously provide tension to the cantilever of the two rows of facing precast concrete structures, further strengthening the connection between the cantilever of the two rows of facing precast concrete structures, thereby enhancing the overall integrity of the two rows of precast concrete structures.

[0029] In this embodiment, as Figure 1 As shown, the concrete cantilever horizontal connection assembly 100 also includes a gasket 140, and a bolt 130 can be threaded through the gasket 140 and the first through hole to be threadedly connected to the corresponding threaded sleeve 120. By increasing the force-bearing area, the gasket 140 evenly distributes the pressure to a larger contact area, reducing the pressure per unit area, thereby protecting the integrity of the surface of the first connecting plate 110 or the second connecting plate.

[0030] The working principle of this utility model: When it is necessary to construct two rows of precast concrete buildings facing each other, such as Figure 3 As shown, firstly, threaded sleeves 120 are pre-embedded in the cantilever of the precast concrete structure. Then, two rows of precast concrete structures facing each other are erected. Finally, the bolt 130 passes through the first through hole and is threadedly connected to the corresponding threaded sleeve 120. The nut of the bolt 130 presses and fixes the first connecting plate 110 to the threaded sleeve 120. The first connecting plate 110 connects the cantilever of the two rows of precast concrete structures facing each other, thereby strengthening the overall integrity of the two rows of precast concrete structures. This concrete cantilever horizontal connection assembly 100 has the advantages of simple structure and easy operation.
