Description

Technical Field

[0001] The invention belongs to assembled buildings, and in particular relates to a connector and a prefabricated component for positioning stress reinforcement bars. Background Art

[0002] The assembled wall includes the exterior wall and the interior wall. The exterior wall and / or the interior wall can be formed into standard prefabricated components in the factory by using molds. During the construction of the assembled building, the exterior wall is hung on the interior wall. The existing exterior wall is usually hung on the interior wall in the following three ways: 1. A screw sleeve is provided on the exterior wall, and an expansion bolt is provided on the interior wall. The screw sleeve is screwed on the expansion bolt to realize the hanging of the exterior wall on the interior wall; 2. A clip is provided on the exterior wall, and a slot is provided on the interior wall. The clip is inserted into the slot to realize the clip connection of the exterior wall to the interior wall; 3. An external connecting piece is provided on the exterior wall, and an internal connecting piece is provided on the interior wall. The external connecting piece and the internal connecting piece are connected by bolts or screws.

[0003] However, components such as screw sleeves, clips and external connecting parts are only installed on the concrete on the exterior wall. If the structural strength of the concrete of the exterior wall itself is insufficient, or if the aforementioned components are close to cracks or defects such as honeycombs and rough surfaces in the concrete on the exterior wall, this will result in a lack of connection strength between the hanging mechanism and the exterior wall. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a connector and a prefabricated component for positioning stress-bearing reinforcements, so as to optimize the performance of the prefabricated component.

[0005] In order to solve the above technical problems, the present invention provides a connecting piece for positioning a stress-bearing bar, comprising:

[0006] An installation section is arranged in the prefabricated component, the installation section is provided with an installation cavity for connecting a stress-bearing rib, the installation cavity is provided with a first inlet and a first outlet corresponding to the first inlet, and the stress-bearing rib is inserted into the installation cavity from the first inlet and leaves the installation cavity from the first outlet;

[0007] The fixing section is arranged on the installation section, and the fixing section is provided with a mounting hole for connecting one end of the suspension rib.

[0008] Furthermore, it also includes:

[0009] An extension section is arranged on the installation section and is used to control the spacing distance between the stress-bearing reinforcement and the side wall of the prefabricated component.

[0010] Furthermore, the extending section is arranged on the outside of the installing section, and the fixing section is arranged on the inside of the installing section.

[0011] Furthermore, the extending section, the mounting section and the fixing section are integrally formed.

[0012] Furthermore, the radial dimension of the end of the extension section is reduced.

[0013] Furthermore, the end of the extension section is in a truncated cone shape; or, the end of the extension section is in a conical shape.

[0014] Furthermore, the installation cavity is provided with a second inlet and a second outlet corresponding to the second inlet, and the stress-bearing rib is inserted into the installation cavity from the second inlet and leaves the installation cavity from the second outlet.

[0015] Further, the first inlet is arranged inside the second inlet, and the first outlet is arranged inside the second outlet.

[0016] The prefabricated components include an exterior wall and an interior wall, and also include a connecting piece and a hanging rib. The connecting piece is the connecting piece described in any of the above technical solutions, the connecting piece is arranged on the exterior wall, one end of the hanging rib is arranged on the connecting piece, and the other end of the hanging rib is arranged on the interior wall.

[0017] Furthermore, the hanging ribs are embedded in the inner wall.

[0018] Existing screw sleeves, buckles, external connectors and other components are fixedly installed on the concrete of the exterior wall. Compared with the prior art, the connector of the present invention includes a mounting section, a mounting cavity is provided on the mounting section, and a stress-bearing bar is provided in the exterior wall. When the stress-bearing bar is connected to the mounting cavity, the connector is fixed to the exterior wall through the mounting section. Such a design optimizes the performance of the prefabricated component by increasing the connection strength between the connector and the exterior wall.

[0019] As a decorative wall, the thickness of the exterior wall is usually less than 60mm. The screw sleeves, buckles, external connectors and other components are fixedly installed on the concrete of the exterior wall, which will cause the exterior wall to crack easily during the process of connecting the screw sleeves, buckles or external connectors. However, the present invention first connects the connector to the stress reinforcement, and then forms the exterior wall in the forming mold, which can effectively prevent the exterior wall from cracking during the installation of the connector.

[0020] The existing exterior wall and interior wall are formed separately and then connected together through a hanging mechanism. Therefore, the assembled wall requires high position accuracy and high anti-deformation strength of the hanging mechanism. The fixed section of the present invention is provided with a mounting hole, and the mounting section is arranged in the exterior wall. When one end of the hanging rib is connected to the mounting hole, the other end of the hanging rib can be buried in the cast-in-place interior wall. That is, after the installation position of the connecting piece on the exterior wall is determined, the hanging rib can drive the exterior wall to perform stepless adjustment of the installation position relative to the interior wall. Such a design improves the relative position accuracy of the exterior wall and the interior wall, and realizes the molding of prefabricated components in a pair of molds.

[0029] In order to facilitate the understanding of the technical solution of the present invention, a detailed description is given below in conjunction with the accompanying drawings and specific embodiments.

[0030] Embodiment 1

[0031] See also Figure 1 , Figure 4 and Figure 5 , a connector 100 for a prefabricated component 1, the connector 100 comprising:

[0032] The installation section 1020 is arranged in the prefabricated component 1. The installation section 1020 is provided with an installation cavity 1040 for connecting the stress-bearing rib 300. The installation cavity 1040 is provided with a first inlet 1041 and a first outlet 1042 corresponding to the first inlet 1041. The stress-bearing rib is inserted into the installation cavity 1040 from the first inlet 1041 and leaves the installation cavity 1040 from the first outlet 1042. In this embodiment, the stress-bearing rib is referred to as the first stress-bearing rib 300.

[0033] The fixing section 1010 is disposed on the mounting section 1020 , and a threaded hole 1011 for connecting one end of the suspension rib 200 is provided on the fixing section 1010 .

[0034] In this embodiment, the connecting member 100 further includes:

[0035] The extension section 1030 is arranged on the installation section 1020 and is used to control the spacing distance between the stress reinforcement and the side wall of the prefabricated component 1; Figure 4 and Figure 5 It can be seen that the extension section 1030 controls the spacing distance between the first stress-bearing reinforcement 300 and the side wall of the exterior wall 12 to ensure that the first stress-bearing reinforcement 300 is buried at a predetermined depth position of the exterior wall 12 .

[0036] See also Figure 2 and Figure 5 , the end surface of the extension section 1030 can be exposed on the side wall of the outer wall 12, so the radial dimension of the end of the extension section 1030 is reduced. Preferably, the end 1031 of the extension section 1030 is truncated cone-shaped, and the end 1031 of the truncated cone-shaped extension section 1030 can effectively reduce the area ratio coefficient of its end surface on the side wall of the outer wall 12. In addition, the end 1031 of the extension section 1030 can also be conical.

[0037] See also Figure 2 and Figure 5 , the extension section 1030 is arranged on the outside of the installation section 1020, the fixed section 1010 is arranged on the inside of the installation section 1020, the extension section 1030 controls the distance between the first force-bearing rib 300 and the outer wall of the outer wall 12, and the fixed section 1010 controls the distance between the first force-bearing rib 300 and the inner wall of the outer wall 12. This structure is for the installation method of the connector 100 on the outer wall 12 when the outer wall 12 is arranged on the outer side of the inner wall 11 as a decorative wall; when the outer wall 12 is arranged on the inner side of the inner wall 11 as a decorative wall, the installation method of the connector 100 on the outer wall 12 can be: the extension section 1030 is arranged on the inner side of the installation section 1020, and the fixed section 1010 is arranged on the outer side of the installation section 1020.

[0038] In this embodiment, in order to enhance the anti-deformation strength of the connecting member 100 , the extending section 1030 , the mounting section 1020 and the fixing section 1010 are integrally formed.

[0039] See also Figure 1 and Figure 2 The installation cavity 1040 is also provided with a second inlet 1043 and a second outlet 1044 corresponding to the second inlet 1043, and the first stress rib 300 is inserted into the installation cavity 1040 from the second inlet 1043 and leaves the installation cavity 1040 from the second outlet 1044. The second inlet 1043 and the second outlet 1044 are used to further enhance the connection strength between the connector 100 and the first stress rib 300. In addition, when two first stress ribs 300 are provided on the installation cavity 1040, the connection strength between the two first stress ribs 300 is also enhanced.

[0040] See also Figure 6 and Figure 7The first stress-bearing reinforcement 300 includes a first longitudinal stress-bearing reinforcement 3001 and a first transverse stress-bearing reinforcement 3002. A plurality of first longitudinal stress-bearing reinforcement 3001 and a plurality of first transverse stress-bearing reinforcement 3002 are connected to each other to form a steel mesh. The first longitudinal stress-bearing reinforcement 3001 is inserted into the installation cavity 1040 from the first entrance 1041 and leaves the installation cavity 1040 from the first exit 1042. The first transverse stress-bearing reinforcement 3002 is inserted into the installation cavity 1040 from the second entrance 1043 and leaves the installation cavity 1040 from the second exit 1044.

[0041] Since the first longitudinal force-bearing ribs 3001 and the first transverse force-bearing ribs 3002 are connected to form a cross shape or a cross-like shape, the first inlet 1041 is arranged inside the second inlet 1043 and the first outlet 1042 is arranged inside the second outlet 1044 .

[0042] Embodiment 2

[0043] See also Figure 3 and Figure 4 The prefabricated component 1 includes an outer wall 12 and an inner wall 11 , and the outer wall 12 is located outside the inner wall 11 .

[0044] See also Figure 5 The prefabricated component 1 also includes a connecting member and a hanging rib 200. The connecting member is the connecting member 100 described in Example 1. The connecting member 100 is arranged on the outer wall 12. One end of the hanging rib 200 is arranged on the connecting member 100, and the other end of the hanging rib 200 is arranged on the inner wall 11.

[0045] In this embodiment, the suspension rib 200 is threadedly connected to the fixed section 1010 on the connector 100. During the process of the molding die forming the outer wall 12, the suspension rib 200 is separated from the connector 100 to prevent the suspension rib 200 from affecting the molding of the outer wall 12 in the molding die; after the outer wall 12 is formed, the suspension rib 200 is fixedly installed on the fixed section 1010; when the suspension rib 200 is fixedly installed on the fixed section 1010, concrete is pumped into the molding die to form the inner wall, so that the other end of the suspension rib 200 is buried in the inner wall 11.

[0046] The suspension rib 200 is a PC steel bar, one end of which is provided with an external thread, a threaded hole 1011 is provided on the fixing section 1010, and the external thread on the PC steel bar is fixedly connected with the threaded hole 1011, so that the PC steel bar is fixedly installed on the connector 100. Alternatively, the suspension rib 200 is a PC steel bar, and a clamping hole for clamping the PC steel bar is provided on the fixing section 1010. Alternatively, the suspension rib 200 is a threaded steel bar, one end of which is provided with an external thread, a threaded hole 1011 is provided on the fixing section 1010, and the external thread on the threaded steel bar is fixedly connected with the threaded hole 1011, so that the threaded steel bar is fixedly installed on the connector 100. Since the anti-deformation strength of the PC steel bar is greater than the anti-deformation strength of the threaded steel bar, in this embodiment, the suspension rib 200 is preferably a PC steel bar.

[0047] See also Figure 4 The prefabricated component 1 also includes an insulation wall 13 , which is arranged between the outer wall 12 and the inner wall 11 . When the hanging ribs 200 are buried in the inner wall 11 , the hanging ribs 200 penetrate the insulation wall 13 .

[0048] See also Figure 4 and Figure 8 , the inner wall 11 is provided with second stress-bearing bars 2, the second stress-bearing bars 2 include second longitudinal stress-bearing bars 21 and second transverse stress-bearing bars 22, a plurality of second longitudinal stress-bearing bars 21 and a plurality of second transverse stress-bearing bars 22 are connected to form a steel cage (or, a plurality of second longitudinal stress-bearing bars 21, a plurality of second transverse stress-bearing bars 22 and a plurality of stirrups are connected to form a steel cage; or, a plurality of second longitudinal stress-bearing bars 21, a plurality of second transverse stress-bearing bars 22 and a plurality of tension bars are connected to form a steel cage; or, a plurality of second longitudinal stress-bearing bars 21, a plurality of second transverse stress-bearing bars 22, a plurality of stirrups and a plurality of tension bars are connected to form a steel cage), and since the inner wall 11 has sufficient thickness, the suspension bars 200 of this embodiment are only fixedly installed on the concrete of the inner wall 11. When the suspension bars 200 are fixedly installed on the concrete of the inner wall 11, the position of the outer wall 12 relative to the inner wall 11 can be adjusted steplessly.

[0049] from Figure 4 It can be seen that the cross section of the prefabricated component 1 of this embodiment is L-shaped. With such a design, the first stress-bearing reinforcement 300 at the corner of the outer wall 12 and the second stress-bearing reinforcement 2 at the corner of the inner wall 11 will not be exposed outside the prefabricated component 1.

[0050] The above are only preferred embodiments of the present invention. The protection scope of the present invention shall be based on the scope defined by the claims.
