Referring to fig. 3, because accomplish the back with the installation of heated board 4, heated board 4 and horizontal limit 32's laminating department can form a straight line concatenation seam, when the straight line concatenation seam has sealed not good place, cause very easily to destroy to the sealed of whole concatenation seam, make the inside and outside air of heated board 4 produce the convection current, cause cold and hot exchange, the air gets into between outer wall 1 and the heated board 4 from concatenation seam department, and then can cause the adhesive to become invalid ageing for a long time, the problem that heated board 4 drops easily. Therefore, the horizontal edge 32 comprises a first horizontal portion 321, a vertical portion 322 and a second horizontal portion 323, the first horizontal portion 321, the vertical portion 322 and the second horizontal portion 323 are sequentially connected to form a Z-shaped structure, one end of the first horizontal portion 321, which is far away from the vertical portion 322, is fixedly arranged on the vertical edge 31, the pressing edge 33 is fixedly arranged on one end of the second horizontal portion 323, which is far away from the vertical portion 322, and one end of the insulation board 4, which is close to the horizontal edge 32, is provided with a step portion 41 which is mutually embedded with the Z-shaped structure of the horizontal edge 32. When the insulation board is used, the L-shaped supporting piece 3 is fixed on the outer wall 1 through the expansion bolt, then the insulation boards 4 located on the upper side and the lower side of the L-shaped supporting piece 3 are installed, the step portion 41 of each insulation board 4 is clamped into the Z-shaped structure of the horizontal edge 32 and is adhered and fixed, when the step portion 41 is clamped into the Z-shaped structure of the horizontal edge 32, the step portion 41 is coated with a layer of sealant for the insulation boards 4, and the step portion 41 is clamped into the horizontal edge 32 and is tightly squeezed to enable the sealant to seal the splicing seam. Through setting the horizontal edge 32 to the Z-shaped structure, the bending path of the splicing seam can be increased, simultaneously, when the insulation board 4 is installed, a layer of sealant is smeared at the step part 41, the splicing seam is filled through the extrusion step part 41, when a place which is not good in sealing exists in the splicing seam, a three sealing loop is formed at the horizontal edge 32, so that when the straight-line splicing seam has a place which is not good in sealing, the problem that the sealing of the whole splicing seam is damaged is easily caused, the sealing effect is better in the arrangement, and the insulation board 4 is more firmly fixed.
Referring to fig. 3, in order to increase the bearing strength of the supporting member 3, reinforcing blocks 324 are respectively and fixedly arranged at the internal corners of the supporting member 3, the reinforcing blocks 324 are in a right triangle shape, and the corresponding positions of the reinforcing blocks 324 on the step portion 41 of the heat insulation plate 4 are cut to form splicing portions 42 capable of being attached to the reinforcing blocks 324. Reinforcing block 324 sets firmly through the reentrant corner department at support piece 3, can increase the intensity in the weak area in support piece 3 turning, prevents that support piece 3 from taking place to warp when receiving the pressure of heated board 4, utilizes reinforcing block 324 to fill support piece 3 reentrant corner department simultaneously, has avoided sealed glue to fill not closely knit problem in reentrant corner department, increases the leakproofness of support piece 3 and heated board 4 splice joint department.
In order to increase the compactness of heated board 4 laminating on outer wall 1, the holding tank has been seted up in expansion bolts's position in the inboard of heated board 4, and the holding tank is used for placing expansion bolts's end, with in expansion bolts's the end position imbeds the holding tank completely, heated board 4 can be inseparable laminating on outer wall 1 wall to increase heated board 4 stability and heat insulating ability on outer wall 1.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
