Description

Technical Field

[0001] The present application belongs to the technical field of thermal insulation board connectors and relates to a structural improvement of a connector. Background Art

[0002] Nowadays, the application of concrete sandwich insulation wall panels in the development of prefabricated buildings is increasing. The connectors in concrete sandwich insulation wall panels are the most critical components. At present, a fixed wire mesh is usually set on the outside of the exterior wall, and the insulation board is installed between the wire mesh and the exterior wall. The insulation board and the wire mesh are fixedly connected using connectors. During the construction process, a concrete layer needs to be poured on the outside of the insulation wall panel.

[0003] The existing patent CN 218346448 U discloses a fixed connector for a steel wire mesh insulation exterior wall panel (application number 202222523778.3), which includes a connecting rod and a steel bar; one end of the connecting rod is threadedly connected to the exterior wall panel, and the other end of the side wall is provided with an installation groove inwardly, and the steel bar bend is arranged in the installation groove; an arc block is also formed on one side of the installation groove; a convex column is also fixedly installed on the bottom wall of the installation groove; the steel bar bend is limited between the arc block and the convex column. A fixed protrusion is fixedly installed on one end of the connecting rod, and the fixed protrusion corresponds to the position of the installation groove. A fixed protrusion is fixedly installed on one end of the connecting rod.

[0004] However, during the pouring process, the following problems may occur: (1) The head of the connector is convex (fixed convex in CN 218346448U), and the surface of the concrete layer is uneven after pouring. This will also affect the stability between the concrete layer and the insulation board to a certain extent.

[0044] As a specific implementation method, Figure 1-3 As shown, a structural improvement of a connecting piece includes:

[0045] A first clamping member 1, a second clamping member 2, a first adjusting head 3, and a second adjusting head 4 respectively arranged at two ends of a connecting rod 7;

[0046] The first clamping member 1 and the second clamping member 2 include a bonding plate 5 with a through hole in the middle, and a stabilizing inclined section 6 disposed above the bonding plate 5 and along the circumference of the bonding plate 5;

[0047] The connecting rod 7 passes through the through holes of the fitting disc 5 in the first clamping member 1 and the second clamping member 2 and is connected to the first adjusting head 3 and the second adjusting head 4 respectively; a fixing column 8 is arranged above the stabilizing inclined section 6 of the first clamping member 1, and a first groove adapted to the fixing column 8 is arranged on one side of the first adjusting head 3 close to the first clamping member 1;

[0048] A centrally symmetrical stabilizing block 9 is disposed on one side of the second adjusting head 4 close to the second clamping member 2; the spacing between the centrally symmetrical stabilizing blocks 9 is greater than the width of an end portion of the stabilizing inclined section 6 in the second clamping member 2 close to the second adjusting head 4;

[0049] The connecting rod 7 is provided with a spiral convex pattern 12 extending along the length direction of the connecting rod 7 at the end, and the through hole surface of the bonding disk 5 is provided with a spiral concave pattern matching the spiral convex pattern 12; the first clamping member 1, the second clamping member 2 are connected to the connecting rod 7 by threaded rotation.

[0050] The first adjusting head 3, the second adjusting head 4 and the connecting rod 7 are connected by threads. During installation, after the connecting rod 7 passes through the insulation board, the first adjusting head 3, the second adjusting head 4 and the insulation board are connected by threads.

[0051] Specifically, during use, the connecting rod 7 is rotated, and under the threaded movement of the spiral grooves on the inner side of the through hole of the first clamp 1 and the spiral convex grooves 12 on the surface of the connecting rod 7, a part of the fixing column 8 above the stabilizing inclined section 6 gradually enters the first groove of the first adjusting head 3, thereby realizing the fitting of the first adjusting head 3 and the first clamp 1; the first adjusting head 3 is fitted to the outer side of the wire mesh, so that the transverse steel wire of the wire mesh is clamped at the connection between the first adjusting head 3 and the fixing column 8, and the side of the fixing column 8 is tightly fitted to the vertical steel wire of the wire mesh; and then the fitting disk 5 on the first clamp 1 is fitted to one side of the insulation board.

[0052] The second clamp 2 is attached to the other side of the insulation board, and the second adjusting head 4 is rotated. The second adjusting head 4 moves around the connecting rod 7 by threading until it is attached to the outside of the wire mesh on the other side and is attached to the stabilizing inclined section 6 in the second adjusting head 4. At this time, the stabilizing block 9 arranged on one side of the second adjusting head 4 is tightly attached to the outside of the stabilizing inclined section 6 in the second adjusting head 4, thereby enhancing the stability between the second component and the second adjusting head 4.

[0053] The first adjustment head 3 and the second adjustment head 4 are respectively connected to the first clamp 1 and the second clamp 2 by threads. The threaded connection can achieve the fitting and separation between the adjustment head and the clamp, so as to adjust the degree of fit between the connector and the wire mesh and enhance its stability.

[0054] The setting of the fixing column 8 and the first groove makes the first adjusting head 3 and the first clamp 1 more firmly connected on the one hand, and on the other hand, during the pouring process, the gap between the fixing columns 8 can allow concrete to be poured, so that the connecting piece can be better integrated with the concrete poured wall, thereby enhancing the fit and stability of the head end of the connecting piece and the poured wall.

[0055] Furthermore, the stabilizing oblique section 6 extends from the circumferential edge of the fitting plate 5 toward the first adjusting head 3 and the second adjusting head 4. The design of the stabilizing oblique section 6 can increase the load-bearing capacity of the connector during concrete pouring, and on the other hand, the narrow opening design close to the adjusting head is more conducive to the fitting of the wire mesh and the adjusting head, thereby enhancing its stability.

[0056] The arrangement of the centrally symmetrical stabilizing block 9 of the second adjusting head 4 can limit and fix the head end of the second clamping member 2 after the second adjusting head 4 and the second clamping member 2 are attached to enhance stability. The number of stabilizing blocks 9 is greater than or equal to 2 and is an even number. In this embodiment, 2 are arranged.

[0057] As a preferred embodiment, the number of the stabilizing inclined sections 6 is at least 4. This allows the concrete pouring to contact the clamp more fully and the pouring distribution to be more uniform.

[0058] As a preferred embodiment, the outer side of the stabilizing inclined section 6 is curved, so as to further increase the contact area with the concrete and enhance the stability.

[0059] As a preferred embodiment, the column surface of the fixing column 8 at one end close to the stabilizing inclined section 6 is configured to be serrated, thereby increasing the contact friction between the fixing column 8 and the wire mesh, thereby enhancing the stability of the connecting piece and the wire mesh.

[0060] As a preferred embodiment, the thickness of the first adjusting head 3 and the second adjusting head 4 is 0.3-0.8 cm, and the width is 1-1.3 cm. The adjusting heads under this volume will not affect the uniformity of the surface of the poured concrete layer.

[0061] As a preferred embodiment, the shapes of the first stabilizing perforation 10 and the second stabilizing perforation include circular, elliptical, and polygonal.

[0062] As a preferred embodiment, a fixing column 8 is provided above the stabilizing inclined section 6 of the first clamp 1, and the length of the fixing column 8 is 1 / 4-1 / 3 of the first clamp 1, so as to avoid the first clamp 1 being too long as a whole, which is inconvenient to transport and cast.

[0063] As a preferred embodiment, the bonding plate 5 is provided with communication holes 11, and the number of the communication holes 11 is at least 4. This allows the bonding plate 5 to be better integrated with the concrete poured wall surface, and enhances the fit and stability of the connector head end with the poured wall.

[0064] As a preferred embodiment, a first stabilizing through hole 10 is provided on the side of the first adjusting head 3, and the first stabilizing through hole 10 is communicated with the first groove; further, the diameter of the first stabilizing through hole 10 is smaller than the diameter of the fixing column 8 above the stabilizing inclined section 6 in the first clamp 1; and a column hole with the same diameter as the first stabilizing through hole 10 is provided on the column body of the fixing column 8.

[0065] During use, when the head end of the fixing column 8 reaches the bottom of the first groove of the first adjustment head 3, the through hole on the fixing column 8 and the first stable through hole 10 are in a through state, and the bolt is inserted into the first stable through hole 10 and passes through the through hole on the fixing column 8 from the other side of the first stable through hole 10. At this time, the bolt is connected to the first adjustment head 3 and the fixing column 8 as a whole. In this way, the stability between the first clamp 1 and the first adjustment head 3 is enhanced. Furthermore, the depth of the first groove is 1 / 3-2 / 5 of the length of the fixing column 8. This depth setting will not make the side of the first adjustment head 3 away from the first clamp 1 too thin, and the insertion length of the consolidation column can be firmly connected to the first adjustment head 3.

[0066] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0067] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
