Description

Technical Field [0001] The present invention relates to the field of building materials, specifically to a fixed device of a thermal insulation board for external wall of a shear wall structure.

Background [0002] Shear wall building structure has become a common building style. In some relatively cold and hot places, the surface of shear wall is generally mounted with a layer of thermal insulation board. The thermal insulation board can greatly reduce the capability of heat conduction of the shear wall, and makes it hard for the outside cold air to freeze the wall body in a short time. However, the installation of conventional thermal insulation board is difficult, labor intensity of working staff is relatively large, and the problem of infirm installation and the problem that the thermal insulation board is prone to fall off exist. Therefore, a fixed device of a thermal insulation board for external wall of a shear wall structure is proposed.

Summary [0003] The objective of the present invention is to provide a thermal insulation board for external wall of a shear wall structure, so as to solve the above problems mentioned in Background.

[0004] A fixed device of a thermal insulation board for external wall of a shear wall structure includes a self-tapping screw. The self-tapping screw is inserted into a threaded hole provided on a main body of the thermal insulation board, and the main body of the thermal insulation board is connected to a wall body through the self-tapping screw. The self-tapping screw is provided with a channel, and the channel is provided with a first plug-in rod in an active insert connection. A lower end of the first plug-in rod is connected to an end of a first spring, and the other end of the first spring is connected to a bottom wall of the channel. The lower end of the first plug-in rod is symmetrically hinged with one end of each of two connecting rods, and the other end of the connecting rod is hinged with a baffle plate. A side wall of the self-tapping screw is symmetrically provided with two slide rails, the two slide rails are interconnected to the channel, a side wall of each slide rail is provided with a strip-like slide slot, and a lower end of the connecting rod is connected inside the strip-like slide slot. A side wall of the threaded hole is symmetrically provided with a groove corresponding to the slide rail. A side wall of the groove is connected to an end of a second spring, and the other end of the second spring is connected to a second plug-in rod. The main body of the thermal insulation board is filled with a thermal insulation layer.

[0005] Preferably, an end of the second plug-in rod far from the second spring has a hemispheroid structure.

[0006] Preferably, an end of the second plug-in rod far from the second spring is covered with a wear-resistance layer.

[0007] Preferably, an upper end surface of the main body of the thermal insulation board is hinged with a cover board, and a side of the cover board close to the self-tapping screw is covered with an adhesive layer.

[0008] Compared with the prior art, the advantages of the present invention are as follows. The self-tapping screw is made to rotate and move downwards by using an electric drill, so that the main body of the thermal insulation board is tightly attached to the wall body. With the downward movement of the self-tapping screw, the groove is on a same horizontal plane as the slide rail. The second plugin rod is inserted into the slide rail to fix the position of the self-tapping screw, thereby avoiding the rotation of the self-tapping screw, and preventing the self-tapping screw from loosening to cause the separation of the main body of the thermal insulation board from the wall body. By rotating the cover board and using the adhesive layer, the surface of the self-tapping screw is covered. The threaded hole is sealed to enhance the thermal insulation effect. When the main body of the thermal insulation board is needed to be disassembled, the first plug-in rod is pressed, by the action of the connecting rod, to make the two baffle plates move away from each other, the second plug-in rod is pushed out of the slide rail, and finally the self-tapping screw is rotated out of the wall body, which is convenient and efficient, saves time and labor.

[0013] Referring to FIGS. 1-2, the technical solution of the present invention is as follows.

[0014] A fixed device of a thermal insulation board for external wall of a shear wall structure includes a self-tapping screw 3. The self-tapping screw 3 is inserted into a threaded hole provided on a thermal insulation board main body 2, and the thermal insulation board main body 2 is connected to a wall body 1 through the self-tapping screw 3. The self-tapping screw 3 is provided with a channel, and the channel is provided with a first plug-in rod 5 in an active insert connection. A lower end of the first plug-in rod 5 is connected to an end of a first spring 6, and the other end of the first spring 6 is connected to a bottom wall of the channel. The lower end of the first plug-in rod 5 is symmetrically hinged with one end of each of two connecting rods 7, and the other end of the connecting rod 7 is hinged with a baffle plate 8. A side wall of the self-tapping screw 3 is symmetrically provided with two slide rails, the two slide rails are interconnected to the channel, a side wall of each slide rail is provided with a strip-like slide slot, and a lower end of the connecting rod 7 is movably connected inside the strip-like slide slot. A side wall of the threaded hole is symmetrically provided with a groove corresponding to the slide rail. A side wall of the groove is connected to an end of a second spring 10, and the other end of the second spring 10 is connected to a second plug-in rod 9. The thermal insulation board main body 2 is filled with a thermal insulation layer 4. An end of the second plug-in rod 9 far from the second spring 10 has a hemispheroid structure. An end of the second plug-in rod 9 far from the second spring 10 is covered with a wear-resistance layer. An upper end surface of the thermal insulation board main body 2 is hinged with a cover board 11, and a side of the cover board 11 close to the self-tapping screw 3 is covered with an adhesive layer 12.

[0015] Working principle: The self-tapping screw 3 is made to rotate and move downwards by using an electric drill, so that the thermal insulation board main body 2 is tightly attached to the wall body 1. With the downward movement of the self-tapping screw 3, the groove is on a same horizontal plane as the slide rail. The second plug-in rod 9 is inserted into the slide rail to fix the position of the self-tapping screw 3, thereby avoiding the rotation of the self-tapping screw 3, and preventing the selftapping screw 3 from loosening to cause the separation of the thermal insulation board main body 2 from the wall body 1. By rotating the cover board 11 and using the adhesive layer 12, the surface of the self-tapping screw 3 is covered. The threaded hole is sealed to enhance the thermal insulation effect. When the thermal insulation board main body 2 is needed to be disassembled, the first plug-in rod 5 is pressed, by the action of the connecting rod 7, to make the two baffle plates 8 move away from each other, the second plug-in rod 9 is pushed out of the slide rail, and finally the self-tapping screw 3 is rotated out of the wall body 1, which is convenient and efficient, saves time and labor.
