Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building wall formwork, and particularly relates to a riveted wall form shell connection structure. Background Art
[0002] The non-removal wall formwork has excellent performance and is in line with the prefabricated and low-energy buildings that the country is vigorously promoting. When in use, an anchor needs to be added inside the formwork to connect the formwork on both sides. The wall thickness of the anchor is limited, generally around 3 mm. The threads formed after the self-tapping screws are drilled in are relatively small, and the tensile force they can withstand is relatively small. In the actual process of pouring concrete, the threads will be flattened, and then fail to produce a bursting accident; and the installation of self-tapping screws is difficult and tiring, and it is difficult to achieve mechanical nailing; secondly, after pouring concrete, the hole needs to be enlarged and the stainless steel self-tapping screws need to be screwed in to prevent the non-removal formwork from loosening and falling off the concrete wall. This requires many processes and is also costly. Utility Model Content
[0003] In view of this, the purpose of the utility model is to provide a rivet-type wall formwork connection structure to improve the connection strength of the formwork in order to address the deficiencies of the prior art.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A rivet-type wall formwork connection structure comprises a template, an anchor and a rivet nut. The rivet nut passes through the template and the anchor in sequence to rivet the two.
[0006] In order to better realize the utility model, further optimization is made in the above structure, which further includes a gasket and a bolt, and the bolt passes through the gasket, the template and is threadedly connected with the rivet nut.
[0007] In order to better realize the utility model, further optimization is made in the above structure, and the gasket is made of metal.
[0008] In order to better realize the utility model, the above structure is further optimized, a countersunk hole is opened on the template at the position in contact with the rivet nut, and the rivet nut is inserted into the countersunk hole.
[0009] In order to better realize the utility model, further optimization is made in the above structure, and the template is a cement fiber board.

[0012] In order to better realize the utility model, further optimization is made in the above structure, and the rivet nut is made of galvanized or stainless steel.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] The rivet-type wall formwork connection structure provided by the utility model adopts rivet nuts to rivet the formwork and the anchor. By using bolts and rivet nuts to connect, it can withstand greater tensile force than using self-tapping screws to penetrate the anchor. Since the holes for installing the rivet nuts can be opened in advance, the difficulty of subsequent nailing is reduced. After the concrete solidifies, some rivet nuts can continue to be used as fulcrums during decoration. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.
[0021] In the description of the present utility model, it should be noted that, unless otherwise specified, "multiple" means two or more; the orientations or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present utility model. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0022] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
[0023] Reference Figure 1 and Figure 2 The utility model provides a rivet-type wall formwork connection structure, comprising a template 1, a tie piece 2 and a rivet nut 3. In this embodiment, the template 1 is made of cement fiber board. The rivet nut 3 is made of galvanized or stainless steel to prevent rust. The rivet nut 3 passes through the template 1 and the tie piece 2 in sequence to rivet the two. Since the hole for installing the rivet nut 3 can be opened in advance, the difficulty of subsequent nailing is reduced.
[0024] It also includes a gasket 4 and a bolt 5. The gasket 4 is made of a relatively strong metal material. The bolt 5 passes through the gasket 4 and is threadedly connected to the rivet nut 3. Compared with the self-tapping screw, it can withstand greater tension. The gasket 4 increases the contact area between the bolt 5 and the template 1 to overcome the lateral pressure generated by pouring concrete and prevent the template 1 from being deformed too much and damaged under the pressure of the concrete. After the concrete solidifies, the rivet nut 3 can continue to be used as a focus point for decoration, which is highly practical.
[0025] A conical or stepped countersunk hole 101 is provided at the portion of the template 1 that contacts the rivet nut 3. The rivet nut 3 is inserted into the countersunk hole 101 so that the top of the rivet nut 3 is lower than the side of the template 1. This can firstly prevent the rivet nut 3 from protruding during subsequent home improvement construction, causing an uneven wall surface. Secondly, there is no obstruction between the gasket 4 and the side of the template 1, and the fit is tighter, which can provide more uniform supporting force.
[0026] The anchor 2 is made of a relatively strong metal material, which provides sufficient strength support for the connection. The end of the anchor 2 is an L-shaped structure, which increases the contact area between the anchor 2 and the template 1.
[0027] Working principle: holes for installing rivet nuts 3 are opened in advance when producing the anchor 2 and the template 1. When in use, a rivet gun is used to pass the rivet nuts 3 through the template 1 and the anchor 2 in turn to rivet the two. When concrete needs to be poured, bolts 5 are used in advance to pass through the gasket 4 and threadedly connect the rivet nuts 3 so that the gasket 4 fits the template 1 to overcome the lateral pressure generated by pouring concrete. Finally, after the concrete solidifies, the bolts 5 and gaskets 4 are removed. Some rivet nuts 3 can be used as fulcrums during decoration, and the unnecessary rivet nuts 3 can be directly filled in without affecting the flatness of the wall appearance.
[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
