DETAILED DESCRIPTION
[0029] The technical solutions of the application will be described clearly and completely below with reference to the drawings, obviously, the described embodiments are part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the application.
[0030] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0031] (Example 1) like Figures 1 to 5 As shown, this embodiment is a double-layer composite board connection system, the structure of which includes a stock keel, an outer plate 4, an inner plate 3, and a mounting connector 2.
[0032] The frame keel 5 is installed on the surface of the wall 1 to provide connection points for the connectors. The frame keel 5 is generally made of square steel, and its position is determined according to the position and shape of the double-layer composite panel. The connectors 2 are installed at the edges around the double-layer composite panel, so the frame keel 5 needs to be fixedly installed on the wall 1 at the positions corresponding to the edges of the double-layer composite panel.
[0033] The double-layer composite panel includes an outer panel 4 and an inner panel 3. The outer panel 4 is used to create various shapes, while the inner panel 3 is generally a sound-absorbing panel used for noise reduction indoors. The outer panel 4 includes a face panel and flanges that are folded inward around the face panel. The inner panel 3 is a flat panel structure located within the area enclosed by the flanges of the outer panel 4. The outer panel 4 and the inner panel 3 are connected as one unit by a mounting connector 2.
[0034] The inner panel 3 has the same outline shape as the outer panel 4, and the outline of the inner panel 3 is slightly smaller than that of the outer panel 4, so that there is a gap between the inner panel 3 and the outer panel 4 for the installation connector 2 to pass through.
[0035] A hollow design 4-1 can be provided on the panel of the outer sheet 4.
[0036] The mounting connector 2 specifically includes a first connecting plate 2-1, a second connecting plate 2-2, and a third connecting plate 2-3, which are integrally formed. The second connecting plate 2-2 and the third connecting plate 2-3 are located on both sides of the first connecting plate 2-1. The second connecting plate 2-2 is located at the end of the first connecting plate 2-1 and is perpendicular to the surface of the first connecting plate 2-1. The third connecting plate 2-3 is located in the middle of the first connecting plate 2-1 and is perpendicular to the surface of the first connecting plate 2-1.
[0037] The first connecting plate 2-1 is used to connect with the inner side of the turned edge, the second connecting plate 2-2 is used to connect with the skeleton keel 5, and the third connecting plate 2-3 is used to connect with the inner side plate 3.
[0038] The first connecting plate 2-1 is connected with the turned edge through the first connecting piece 8, the third connecting plate 2-3 is connected with the inner side plate 3 through the second connecting piece 9, and the second connecting plate 2-2 is connected with the skeleton keel 5 through the third connecting piece 10.
[0039] The first connecting piece 8 and the second connecting piece 9 are rivet bolts or screws, and the third connecting piece 10 is a bolt or a screw.
[0040] The profile of the double-layer composite board can be designed into various shapes such as rectangular, hexagonal, triangular and the like, and the double-layer composite boards can be spliced with each other to cover the target area on the wall 1, thereby achieving the effects of decoration and sound absorption.
[0041] The outer side plate 4 is a polygonal structure, and at least two mounting connecting pieces 2 are arranged on each side of the outer side plate 4 to ensure the connection strength of the double-layer composite board.
[0042] In order to avoid the interference between the mounting connecting pieces 2 of the adjacent two double-layer composite boards when they are spliced with each other, the mounting connecting pieces 2 on the same side of the adjacent two outer side plates 4 are arranged staggered with each other, and for the indoor wall surface modeling formed by splicing the polygonal double-layer composite boards of the same shape, the mounting connecting pieces 2 on the opposite two sides of the polygonal double-layer composite board are arranged staggered with each other.
[0043] The skeleton keel 5 is connected with the anchor bolt 7 on the wall 1 through the L-shaped corner code 6, and the skeleton keel 5 is fixedly installed on the wall 1 to provide a connection basis for the installation of the double-layer composite board.
[0044] A long strip-shaped connecting hole is formed in the second connecting plate 2-2 to avoid the problem that the double-layer composite board cannot be connected with the skeleton keel 5 when the position of the skeleton keel 5 deviates.
[0045] (Example two) The embodiment is a double-layer composite board connecting and fixing method, which is realized based on the double-layer composite board connecting system disclosed in example one and includes the following steps.
[0046] a. The inner side plate 3 and the outer side plate 4 of the double-layer composite board are manufactured in the factory.
[0047] The shape of the outer plate 4 is consistent with the prior art before the improvement, but the inner plate 3 is improved to eliminate the flanging structure, and the profile of the inner plate is smaller than the inner profile of the outer plate 4, which simplifies the structure of the inner plate 3, makes the production more simple, and saves the material. Since the inner plate 3 is generally an aluminum sound-absorbing plate, the manufacturing cost of the double-layer composite board can be saved.
[0048] b. Determine the size of the connecting fixing point according to the thickness, width and length of the double-layer composite board.
[0049] On one side of the double-layer composite board, the connecting fixing point is generally arranged at a distance of ≤70mm from the plate edge, and on the other side of the double-layer composite board, the connecting fixing points are arranged staggered and at a distance of ≤150mm from the plate edge. The connecting fixing point is the position where the connecting member 2 is installed.
[0050] c. The first connecting plate 2-1 of the installation connecting member 2 is fixedly connected with the inner side of the flange of the outer plate 4, and the third connecting plate 2-3 is located on the inner side and the second connecting plate 2-2 is located on the outer side.
[0051] d. The inner plate 3 is placed in the area surrounded by the flange of the outer plate 4, the edge of the inner plate 3 is overlapped on the third connecting plate 2-3, and the inner plate 3 is fixedly connected with the third connecting plate 2-3.
[0052] The specific process of connecting the inner plate 3 and the outer plate 4 into a double-layer composite board in the factory through the installation connecting member 2 is as follows: first, the first connecting plate 2-1 of the installation connecting member 2 is attached to the inner side of the flange of the outer plate 4, the third connecting plate 2-3 is located on the inner side, and the second connecting plate 2-2 is located on the outer side, and the first connecting plate 2-1 is fixedly connected with the flange of the outer plate 4 through a flat head rivet; after adjusting the perpendicularity, the inner plate 3 is placed in the area surrounded by the flange of the outer plate 4, the edge of the inner plate 3 is overlapped on the third connecting plate 2-3, and then a flat head rivet is used to fixedly connect the inner plate 3 with the third connecting plate 2-3.
[0053] The inner plate 3 is located inside the outer plate 4, and the accuracy requirements for its shape and size are relatively small, which reduces the processing cost. At the same time, since the connection of the installation connecting member 2 with the outer plate 4 and the inner plate 3 does not affect each other, it is not necessary to open holes in the inner plate 3 for the installation connecting member 2 to pass through and be exposed, and the connection operation is simple and convenient and easy to implement.
[0054] e. Open a connecting hole on the second connecting plate 2-2.
[0055] The connecting hole is a long slot, through which the third connecting member 10 can be stably connected with the skeleton batten 5.
[0056] f. The assembled double-layer composite board is transported to the construction site.
[0057] The production, processing and assembly of the double-layer composite board are completed in the factory, and the assembled double-layer composite board can be directly installed at the construction site, thereby reducing the work amount at the construction site.
[0058] g. The framework batten 5 is fixed on the wall 1 at the construction site according to the shape and installation position of the double-layer composite board.
[0059] h. The assembled double-layer composite board is sequentially spliced and fixed and installed on the framework batten 5 at the construction site.
[0060] The mounting connectors 2 on the opposite two side edges of the double-layer composite board are arranged staggeredly, when the double-layer composite boards are spliced and installed, the first double-layer composite board is installed first, the mounting connectors 2 on all the side edges of the first double-layer composite board are fixedly connected with the framework batten 5 by bolts, when the adjacent double-layer composite board is installed, the second connecting plate 2-2 of the mounting connector 2 on one side is inserted between the first double-layer composite board and the framework batten 5, and the mounting connector 2 on the other side is fixedly connected with the framework batten 5 by bolts, and all the double-layer composite boards are sequentially spliced and fixed and installed on the framework batten 5.
[0061] That is, the double-layer composite board on one side is fixedly connected with the framework batten 5 by the third connecting piece 10, and the second connecting plate 2-2 on the opposite side is inserted into the fixedly connected side of the adjacent double-layer composite board, so that all the double-layer composite boards are fixedly installed on the framework batten 5.
[0062] The mounting connector 2 is adopted in the present application, the form of the connecting and fixing piece between the double-layer composite boards is optimized and designed, the inner side plate 3 and the outer side plate 4 of the double-layer composite board can be quickly connected, the structure of the double-layer composite board is simplified, the material is saved, the production speed of the manufacturer is accelerated, the connection precision and quality of the inner side plate 3 and the outer side plate 4 can be ensured, and the installation and construction efficiency of the double-layer composite board is improved.
