Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific drawings.

Referring to fig. 1, 2, 3 and 4, the wall surface spliced by the putty prefabricated plates sequentially comprises a paint layer 4, a putty prefabricated plate layer and a foundation wall surface from outside to inside. The putty prefabricated plate layer is formed by arranging putty prefabricated plates 1 in an array mode, and a gap between every two adjacent putty prefabricated plates 1 is filled with a joint filling structure 2. During construction, the putty prefabricated plates 1 are prefabricated in a prefabrication factory, and the prefabricated putty prefabricated plates 1 are prefabricated in batches, so that the putty prefabricated plates have good stability and consistency. Then the putty precast slabs 1 are hung on the foundation wall surface, the requirement on the foundation wall surface is low because the putty precast slabs 1 cover the foundation wall surface, the original putty is not allowed to be removed, the interface agent is not allowed to be used, the crack is not allowed to be repaired, and no putty is required to be scraped and no sand paper is used for polishing because of the putty, so that the operation of professional personnel is not required, and the working procedure time can be greatly shortened. And then filling gap filling materials into the gap between two adjacent putty precast slabs 1 to form a gap filling structure. And finally, coating a paint layer 4 on the outer side surfaces of the putty precast slab 1 and the joint filling structure, wherein the paint layer 4 can effectively cover the gap between the putty precast slab 1 and the joint filling structure and the flaw of the joint filling structure.

Putty precast slab 1

The putty precast slab 1 comprises a calcium silicate slab 11, an interface agent covers the outer side surface of the calcium silicate slab 11, the interface agent forms an interface agent layer 12, gypsum covers the outer side surface of the interface agent layer 12, the gypsum forms a gypsum layer 14, putty covers the outer side surface of the gypsum layer 14, and the putty forms a putty layer 13.

The putty precast slab 1 is hung on a foundation wall surface. The putty prefabricated plate 1 can be fixed on the foundation wall surface through nails, pins, hooks and the like. When the putty precast slabs are hung on the foundation wall surface through the hanging rack, the hanging keels can be arranged on the foundation wall surface, and then the hanging hooks are used for hanging the putty precast slabs 1 on the keels. Because the keel is tied to the woodworker operation, not the clay bricklayer operation, the labor cost per unit area is low. More importantly, the keel does not need to be aired, so that compared with a construction mode in the background art, each process needs to wait for the completion of the previous process and the surface of the keel is dried completely, and the construction period is shortened. And the keel is used for correcting the uneven part of the foundation wall surface. The putty precast slab 1 can also be fixedly hung on a foundation wall surface through viscose. In this case, it is preferred that the inner side of the calcium silicate plate is provided with at least two longitudinal grooves 9 extending longitudinally therethrough. So that the longitudinal grooves 9 are used for injecting glue between the putty preformed boards 1 and the foundation wall surface. The inner side surface of the calcium silicate plate can be also provided with at least one transverse groove 8 which extends transversely and penetrates through the calcium silicate plate, and staggered points exist between the transverse groove 8 and the longitudinal groove 9. On one hand, the trend of the viscose can be adjusted by utilizing the transverse groove, redundant viscose is eliminated, and the phenomenon that the viscose overflows to affect the appearance is avoided. On the other hand, the transverse groove increases the space for accommodating the adhesive, so that the adhesive area between the adhesive and the putty precast slab 1 and the foundation wall surface is increased, and the adhesive strength between the putty precast slab 1 and the foundation wall surface is improved. Still more preferably, the lengths of the four sides of the putty preformed sheet 1 are equal. The two transverse grooves are respectively positioned at the upper edge and the lower edge of the putty precast slab 1. The longitudinal grooves are provided with two channels which are respectively positioned at the left edge and the right edge of the putty precast slab 1. The transverse grooves and the longitudinal grooves are integrally in a shape of a Chinese character jing, and the distances from the transverse grooves and the longitudinal grooves to the edge closest to the transverse grooves and the longitudinal grooves are equal. Therefore, the putty precast slabs 1 are in axial symmetry, and constructors do not need to judge whether the putty precast slabs 1 are horizontal or vertical when hanging. Meanwhile, after the putty precast slabs are hung, the transverse grooves of two adjacent putty precast slabs 1 are transversely opposite, and the longitudinal grooves are longitudinally opposite. In addition, the transverse grooves and the longitudinal grooves can also be used as hooks, so that when keel fixing is selected, a hook structure does not need to be additionally arranged on the putty precast slab 1. The distance between the groove walls of the transverse grooves and the longitudinal grooves preferably decreases from the groove bottom in the direction of the groove opening. Thereby make the slope of cell wall, on the one hand, be favorable to increasing the capacity of viscose, on the other hand avoids using as the couple, the degree of difficulty that drops of multiplicable inserted fossil fragments. Preferably, the calcium silicate plate has a thickness of 6-10mm, a width of 1220mm and a length of 2600-2700 mm. The interface agent is made of polyvinyl acetate-ethylene copolymer emulsion, and the thickness of the interface agent layer is 0.1-0.5 mm.

Concerning the caulking structure 2

Where there are no cracks, the caulking structure 2 includes caulking compound overlying the underlying wall surface, gypsum overlying the caulking compound. At the place with crack, filling crack 3 with caulking paste, fixing grid bandage 7 at crack 3, coating caulking paste 5 on grid bandage 7, and finally coating plaster 6 on caulking paste 5. That is, a mesh bandage may be placed between the caulk and the base wall. The gap between the putty precast slabs 1 is preferably 5mm +/-2 mm. The grid bandage is preferably 5mm +/-2 mm in width and not less than the shortest of the four sides of the longitudinal section of the putty preformed board 1. Thereby quickly and conveniently filling the gaps among all the putty precast slabs with the grid bandage. The mesh bandage is preferably a fiberglass mesh bandage.

The outer side surface of the joint filling structure is preferably flush with the outer side surface of the putty prefabricated plate, so that a paint layer covering the joint filling structure and the surface of the putty prefabricated plate is more uniform, and later-stage color difference caused by different thicknesses of the paint layer is avoided.

In order to better combine the putty preformed board with the caulking material, the side wall of the putty preformed board can be provided with a groove 10 with an opening facing the caulking structure. The inner side wall of the groove 10 at the inner side is provided with a through hole 15. Thereby removing excess underfill material through the through-holes. After the construction is finished, the through holes are filled with the joint filling materials, so that the connection strength of the joint filling structure and the putty precast slab is further improved. The grooves are preferably made in a calcium silicate board.
