Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of thermal insulation board connectors and relates to 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, so the research on the working performance of connectors is the key to the research of concrete sandwich wall panels.
[0003] 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 by a connector. During the construction process, it is necessary to pour a concrete layer on the outside of the insulation wall panel. However, during the pouring process, the shape and volume of the end of the connector will affect the uniformity of the surface of the poured concrete layer to a certain extent. It will also affect the stability between the concrete layer and the insulation board to a certain extent. Therefore, it is necessary to set up a new type of connector that can not only ensure the stability between the insulation board and play a certain role in consolidating the exterior wall, but also ensure the flatness and uniformity of the surface of the poured concrete layer. Utility Model Content
[0004] In order to solve the above problems, the present application proposes a connecting piece; through the setting of a specific structure, the connecting piece can not only ensure the stability between the insulation board and play a certain role in consolidating the exterior wall, but also ensure the flatness and uniformity of the surface of the poured concrete layer.
[0005] The specific technical solutions of this application are as follows:
[0006] The present application provides a connector, comprising:
[0007] A connecting rod, a first connecting head and a second connecting head respectively located at two ends of the connecting rod, and a first adjusting fixing head and a second adjusting fixing head respectively arranged inside the first connecting head and the second connecting head;
[0008] The first adjustment fixing head and the second adjustment fixing head include a circular fixing plate with a through hole in the middle and an arc segment fixedly connected to the circular fixing plate; the arc segment extends from the circumferential edge of the circular fixing plate toward the first connecting head and the second connecting head; and the arc segment is provided with a pouring through hole;
[0009] The connecting rod is provided with a spiral convex pattern extending along the length direction of the connecting rod at the end, and the inner side of the through hole of the circular fixing plate is provided with a spiral concave pattern matching the spiral convex pattern; the first adjusting fixing head and the second adjusting fixing head are rotatably connected to the connecting rod through threads;

[0025] 4. As a preferred embodiment, the thickness of the first connector and the second connector is 0.3-1 cm, and the width is 1-1.5 cm. The connectors of this volume will not affect the uniformity of the surface of the poured concrete layer, and can also fix the insulation board and the wire mesh. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] As a specific implementation method, Figure 1-3 As shown, the present application provides a connecting piece, comprising:
[0040] A connecting rod 8, a first connecting head 1 and a second connecting head 2 respectively located at two ends of the connecting rod 8, and a first adjusting fixing head and a second adjusting fixing head respectively arranged inside the first connecting head 1 and the second connecting head 2;
[0041] The first adjustment fixing head and the second adjustment fixing head include a circular fixing plate 3 with a through hole in the middle and an arc segment 4 fixedly connected to the circular fixing plate 3; the arc segment 4 extends from the circumferential edge of the circular fixing plate 3 toward the first connecting head 1 and the second connecting head 2; the arc segment 4 is provided with a pouring through hole 5;
[0042] The connecting rod 8 is provided with a spiral convex pattern 6 extending along the length direction of the connecting rod 8 at the end, and the inner side of the through hole of the circular fixing plate 3 is provided with a spiral concave pattern matching the spiral convex pattern 6; the first adjusting fixing head and the second adjusting fixing head are rotatably connected to the connecting rod 8 through threads;
[0043] The first connector 1 is a disk with angular edges.
[0044] Specifically, during use, the first adjusting fixing head with spiral grooves on the inner side of the through hole and the connecting rod 8 with spiral convex grooves 6 on the end are connected to the arc segment 4 in the first adjusting fixing head through threads and fit with the first connecting head 1; then the second connecting head 2 (spiral column) is passed through the insulation board until the circular fixing disk 3 in the first adjusting fixing head connected to the first connecting head 1 fits on one side of the insulation board; then the second adjusting fixing head with spiral grooves on the inner side of the through hole is connected to the inner side of the second connecting head 2 through threads and the circular fixing disk 3 in the second adjusting fixing head fits on the other side of the insulation board.
[0045] Furthermore, the second connecting head 2 can be adjusted and fixed on the connecting rod 8 along the length of the connecting rod 8; specifically, the second connecting head 2 and the connecting rod 8 are connected by threads, and the position of the second connecting head 2 can be adjusted along the threads on the connecting rod 8 extending along the length direction of the connecting rod 8 until the second connecting head 2 is connected to the circular fixing plate 3, thereby ensuring that the second adjustable fixing head is firmly attached to the insulation board; ensuring that the connecting piece and the insulation board are firmly attached.
[0046] The first connector 1 is a disc with angular edges (the number of edges in this embodiment is 22, and the specific number can be determined according to the actual situation; all discs with edges are within the protection scope of this application and are not limited by number). During the construction process, the first connector 1 is located in the poured concrete layer. The setting of the disc with angular edges allows the concrete to fully contact the disc during the pouring process, with a small contact gap, and the periphery of the disc is fully covered in the concrete, ensuring the uniformity of the concrete pouring surface. At the same time, the design of the disc with angular edges increases the friction with the fingers; it is more convenient and stable when installing the connecting rod 8.
[0047] The arrangement of the arc segment 4, on the one hand, reduces the volume space of the first adjustment fixing head and the second adjustment fixing head, reduces the obstacles to the pouring uniformity during the pouring process, and on the other hand, reduces the load on the circular fixing plate 3, and enhances the fitting stability between the circular fixing plate 3 and the insulation board. The pouring through holes 5 arranged on the arc segment 4 increase the contact area between the concrete and the connecting piece, and enhances the uniformity and stability of the concrete pouring layer.
[0048] As a preferred embodiment, the number of edge corners of the first connector 1 is greater than or equal to 10, which increases the contact area between the connector and the concrete and ensures uniform contact between the concrete and the connector. The second connector 2 is a spiral column integrated with the connecting rod 8.
[0049] As a preferred embodiment, the surface of the first connector 1 is provided with a plurality of pouring ports 7; the pouring ports 7 are recesses or perforations provided on the surface of the first connector 1. In this way, concrete can be poured inside the end of the connector. When the number of pouring ports 7 is greater than 6, the uniformity and sufficiency of the contact surface between the connector and the concrete can be better ensured.
[0050] As a preferred embodiment, the pouring port 7 is in a polygonal shape. The frame strip formed by the polygon can better retain the concrete inside the connector, thereby better eliminating the convex unevenness formed on the connector after the concrete is poured.
[0051] As a preferred embodiment, the diameter of the pouring port 7 is greater than or equal to 0.2 cm, which can further enhance the uniformity of the surface of the concrete pouring layer.
[0052] As a preferred embodiment, the thickness of the first connector 1 and the second connector 2 is 0.3-1 cm, and the width is 1-1.5 cm. The connectors of this volume will not affect the uniformity of the surface of the poured concrete layer, and can also fix the insulation board and the wire mesh.
[0053] As a preferred embodiment, the number of the arc segments 4 is at least 4, so that the concrete pouring is more uniform.
[0054] As a preferred embodiment, the shapes of the pouring through holes 5 include circular, elliptical and polygonal.
[0055] As a preferred embodiment, the number of the pouring holes 5 is greater than or equal to 2. And the size of each pouring hole 5 does not have to be completely consistent. In this way, positions of different widths of the arc segment 4 can be well covered with concrete.
[0056] As a preferred embodiment, the radial distance between the arc segment 4 and the connecting rod 8 is at least 0.3 cm. Such a spacing allows the concrete to be fully poured between the arc segment 4 and the connecting rod 8, avoiding the pouring dead angle caused by the gap being too small, so that the concrete pouring is more uniform.
[0057] 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.
[0058] 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. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
