Detailed Description

In order to make the technical means, the original characteristics, the achieved purposes and the effects of the utility model easily understood, the utility model is further described below with reference to the specific embodiments and the attached drawings, but the following embodiments are only the preferred embodiments of the utility model, and not all embodiments. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative efforts belong to the protection scope of the present invention.

Specific embodiments of the present invention are described below with reference to the accompanying drawings.

Example 1

As shown in fig. 1-5, the putty precast slab comprises a calcium silicate slab 1, wherein an interface agent layer 2 is arranged on the front surface of the calcium silicate slab 1, a putty layer A3 is arranged on the surface of the interface agent layer 2, a putty layer B4 is arranged on the surface of the putty layer A3, the boundary of the putty layer A3 is four-to-five millimeters different from that of the calcium silicate slab 1, an installation groove 5 is formed in the edge position of the calcium silicate slab 1, an installation hole 6 is arranged on the inner side of the installation groove 5, an expansion screw 7 is arranged inside the installation hole 6, the thickness of the putty layer A3 is four millimeters, the thickness of the putty layer B4 is one millimeter, and the thickness of the interface agent layer 2 is zero point one millimeter.

This practicality is accomplished at the prefabricated plate production after, has just scraped putty in advance on its surface, clears away the uneven part of basic unit's surface height, keeps the level and smooth of wall, not only makes the outward appearance of prefabricated plate better, also makes things convenient for simultaneously to carry out other processing decorations to it after the prefabricated plate installation etc. for the product is compared in common prefabricated plate better has the advantage in the market, and makes the installation of this prefabricated plate comparatively simple through the setting of a mounting hole expansion screw.
