Drawings

Fig. 1 is a schematic structural diagram of a moisture-proof and crack-proof composite foamed cement board.

The reference numbers in the figures are: 1-a first foamed cement board, 2-a second foamed cement board, 3-grooves, 4-gaps and 5-polyurethane foam glue.

Detailed Description

The present invention is further described in detail below with reference to examples so that those skilled in the art can implement the invention with reference to the description.

It will be understood that terms such as "having," "including," and "comprising," when used herein, do not preclude the presence or addition of one or more other elements or groups thereof.

As shown in fig. 1, a moisture-proof and crack-proof composite foamed cement board for heat preservation and insulation of building walls, which comprises a first foamed cement board 1 and a second foamed cement board 2 which are stacked up and down, wherein a plurality of grooves 3 are uniformly arranged on the lower surface of the first foamed cement board along the transverse direction or the longitudinal direction, so that the lower surface of the first foamed cement board is a wavy or zigzag curved surface, the upper surface of the second foamed cement board is a curved surface which is matched with the shape of the lower surface of the first foamed cement board, a gap is arranged between the first foamed cement board and the second foamed cement board, and polyurethane foam 4 is filled in the gap. The polyurethane foam adhesive in the gaps forms an interlayer which can prevent moisture erosion, and has the effects of shock absorption, sound absorption and heat insulation, so that the overall performance of the composite foamed cement board is better; and due to the existence of the interlayer, the cracking probability of the first foamed cement board and the second foamed cement board can be reduced to a certain extent, the cracking severity is reduced, even if one of the first foamed cement board or the second foamed cement board cracks, the crack cannot influence the other foamed cement board, and the overall performance of the composite foamed cement board is ensured. The arrangement of the groove enables the splicing and positioning of the first foamed cement board and the second foamed water to be easier during production, the product integrity is better, and the method is also favorable for increasing the overall compressive strength and the like of the composite foamed cement board.

And a filling pipe 5 is arranged at the bottom of each groove on the lower surface of the first foamed cement board and is used for supporting a gap between the first foamed cement board and the second foamed cement board.

The filling pipe is provided with a plurality of through holes, so that the filling pipe is used as a channel for filling polyurethane foam glue. When the polyurethane foam adhesive is filled, the polyurethane foam adhesive can be injected from one end or two ends of the filling pipe, and the gap is quickly filled by the transmission of the filling pipe, so that the filling of the polyurethane foam adhesive is more sufficient and uniform.

The filling pipe material is made of steel or engineering plastics. The filling pipe can also play a role of a reinforcing rib, so that the transverse or longitudinal supporting strength of the composite foamed cement board is higher.

The filling pipe and the polyurethane foam adhesive are preferably fireproof materials above B1 grade.

The length of the filling pipe is not more than that of the first foamed cement board. The two ends of the filling pipe can be flush with the edge of the composite foamed cement board or slightly shorter.

The filling thickness of the polyurethane foam adhesive is not less than 1/10 of the whole thickness of the composite foamed cement board.

While the embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields suitable for the invention, and further modifications may be readily made by those skilled in the art, and the invention is therefore not limited to the specific details and embodiments shown and described herein, without departing from the general concept defined by the claims and their equivalents.
