Detailed Description of the Invention

[0018] The following further describes the specific embodiments of the present utility model in conjunction with the drawings. It should be noted here that the description of these embodiments is for helping to understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] The present utility model provides as Figures 1-5A kind of fireproof and heat-insulating board for building walls shown in the figure includes a heat-insulating board body 1. A number of convex points 4 are provided on the outer surface of the heat-insulating board body 1. The convex points 4 are arranged on the outer surface of the heat-insulating board body 1 and are integrally formed with the heat-insulating board body 1. A spraying layer 5 is also provided on the outer surface of the heat-insulating board body 1. The spraying layer 5 can be a pattern for decorative purposes or a rainproof and sunscreen coating. A clamping block 2 is provided on one side surface of the heat-insulating board body 1, and a clamping groove 3 is provided on the side surface of the heat-insulating board body 1 opposite to the clamping block 2. The clamping block 2 is adapted to the clamping groove 3. By clamping the clamping block 2 into the clamping groove 3 of the adjacent heat-insulating board body 1, the adjacent heat-insulating board bodies 1 can be simply connected, which can increase the integrity and avoid local detachment. A positioning clamping hole 7 is provided on the inner surface of the heat-insulating board body 1. An inclined hole 6 is provided on one side of the positioning clamping hole 7, and the inclined hole 6 extends to the outside of the heat-insulating board body 1. The number of the positioning clamping holes 7 is not less than two. When using adhesives such as cement mortar to bond the heat-insulating board body 1 to the wall surface, part of the cement mortar can enter the inclined hole 6 and the positioning clamping hole 7, further improving the overall bonding effect and making this side of the heat-insulating board body 1 less likely to fall off;

[0020] A clamping hole connecting block 10 is clamped inside the positioning clamping hole 7. An inserting column 9 is provided on the side surface of the clamping hole connecting block 10 and outside the heat-insulating board body 1. The inserting column 9 passes through a notch 8. The notch 8 is provided outside the positioning clamping hole 7 and communicates with the inclined hole 6. The setting of the inclined hole 6 facilitates the clamping of the clamping hole connecting block 10 into the positioning clamping hole 7. Two expansion blocks 11 are symmetrically arranged in the middle of the inserting column 9. There is a through hole between the two expansion blocks 11. An activity hole 16 is provided on the clamping hole connecting block 10 and the inserting column 9. An activity column 13 is movably arranged in the activity hole 16. A conical plug 14 is provided at the lower end of the activity column 13. The diameter of the through hole is smaller than the diameter of the activity column 13. When the activity column 13 moves downward, the conical plug 14 gradually squeezes the two side expansion blocks 11. The inserting column 9 is inserted into a reserved hole in the wall, and the expansion blocks 11 squeeze the reserved hole, making the inserting column 9 not easy to fall off.

[0021] A retaining strip 18 is arranged in the positioning clamping hole 7. The retaining strip 18 is located at the junction of the positioning clamping hole 7 and the inclined hole 6 and is made of elastic rubber material, which is convenient for the clamping hole connecting block 10 to be clamped. And holes are provided on the retaining strip 18. When the cement mortar soaks into the holes and dries, it can well prevent the falling off of the clamping hole connecting block 10.

[0022] The expansion blocks 11 are connected by a connecting strip. The connecting strip is integrally injection-molded with the expansion blocks 11. When the expansion blocks 11 are squeezed by the conical plug 14, the connecting strip breaks, which does not affect the outward movement of the expansion blocks 11.

[0023] An outer end of the movable column 13 and located outside the card hole connecting block 10 is provided with a force-bearing plate 12 for bearing force, usually by hammering. The outer end face of the card hole connecting block 10 is provided with a counterbore adapted to the force-bearing plate 12, so that the force-bearing plate 12 can sink into the counterbore.

[0024] An upper part of the inner wall of the movable hole 16 is provided with a clamp 17, and an upper part of the outside of the movable column 13 is provided with a snap ring 15. When the movable column 13 moves inward, the snap ring 15 is stuck inside the clamp 17, and the snap ring 15 is restricted by the clamp 17 to prevent the movable column 13 from accidentally returning.

[0025] During the use of the building wall fireproof insulation board, an adhesive such as cement mortar is evenly applied to the insulation board body 1 and the corresponding wall surface, and then the insulation board body 1 is pasted on the wall surface. Part of the cement mortar can enter the inclined holes 6 and the positioning card holes 7, further improving the overall bonding effect and making it more difficult for the insulation board body 1 to fall off on this side; when it is necessary to further improve the connection strength, a hole is drilled or a reserved hole is provided on the wall, the plug column 9 is inserted into the hole and then the force-bearing plate 12 is hammered, and the movable column 13 moves inward. The expansion block 11 is squeezed by the tapered plug 14 and moves outward to firmly fix the plug column 9. Then, the insulation board body 1 is moved along the inclined holes 6, and the card hole connecting block 10 is snapped into the positioning card hole 7 to firmly fix the insulation board body 1 and make it more difficult to fall off.

[0026] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
