Editorial Note 2015100717 There are 2 pages of description A thermal insulation building board Technical field This INNOVATION PATENT relates to a thermal insulation building board. Background technology The wall, floor and roof of existing buildings are made of boards or bamboo boards which are fixed on the framework. There are such shortcomings as waste of materials, heavy weight, poor intensity, poor sound insulation and thermal insulation effects, poor shock resistance and low installation efficiency. Besides, some existing patterns are directly carved, painted or pasted on the wall, floor and roof. In this way, maintenance and replacement are inconvenient. Invention content The technical problem to be solved by this INNOVATION PATENT is to provide a building board which is convenient for assembly and installation. Besides, it owns high intensity, good thermal insulation effect and certain decorative effect. To solve the above problem, this INNOVATION PATENT adopts the following technical proposal: A thermal insulation building board includes more than one building board, the first side board and the second side board which are connected with left and right ends of building board via industrial rubber. A cavity forms in the building board. More than one reinforcing rib is set up in the cavity. There is a groove on the first side board, and there is a bump on the second side board which can be connected with the groove. The bottom of right side of building board is fixedly connected with a bearing board. A pattern layer is set up on the bearing board. As an optimized technical proposal, a groove which is used to place the pattern layer is set up on the bearing board; the pattern layer is connected with the groove. Beneficial effects of this INNOVATION PATENT are as follows: Such thermal insulation building board owns high intensity and high assembly efficiency, and can be installed conveniently and fast. The pattern layer is set up at the front end of building board by the bearing board to effectively improve decoration and variability of building board. If the pattern layer is damaged, it is convenient for replacement. People can replace the pattern layer according to their preference at will. Descriptions of attached figures To explain it easily, this INNOVATION PATENT is detailed by the following specific implementation example and the attached figures.
Fig.1 shows structure diagram of this INNOVATION PATENT. Fig.2 shows schematic diagram of the front of this INNOVATION PATENT. Detailed implementation way As shown in Fig.1 and Fig.2, a thermal insulation building board includes more than one building board 1, the first side board 2 and the second side board 3 which are connected with left and right ends of building board 1 via industrial rubber. A cavity 4 forms in the building board 1. More than one reinforcing rib 5 is set up in the cavity 4. There is a groove 6 on the first side board 2, and there is a bump 7 on the second side board 3 which can be connected with the groove 6. The bottom of right side of building board 1 is fixedly connected with a bearing board 9. A pattern layer 8 is set up on the bearing board. A groove (not shown in the figure) which is used to place the pattern layer 8 is set up on the bearing board 9; the pattern layer 8 is connected with the groove (not shown in the figure) for the convenience of installation and replacement of the pattern layer 8. Beneficial effects of this INNOVATION PATENT are as follows: Such thermal insulation building board owns high intensity and high assembly efficiency, and can be installed conveniently and fast. The pattern layer is set up at the front end of building board by the bearing board to effectively improve decoration and variability of building board. If the pattern layer is damaged, it is convenient for replacement. People can replace the pattern layer according to their preference at will. The above is a specific implementation way of this INNOVATION PATENT. However, the protection scope of this INNOVATION PATENT is not limited to this. Any change or replacement without creative work shall be covered in the protection scope of this INNOVATION PATENT. Therefore, the protection scope of this INNOVATION PATENT shall be subject to that defined in the claim.
