Description of the reference numerals
In the figure: 1 is imitative stone material architectural surface, 2 is the heat preservation, 3 is first built-in fitting, 4 is first connecting piece, 5 is the rubber and plastic sponge, 6 is the decoration floor layer, 7 is cement mortar, 8 is flexible resistant weather and dense glue, 9 is the floor, 10 is the roof beam, 11 is the third built-in fitting, 12 is the connecting plate, 13 is the interior wall, 14 is the second built-in fitting, 15 is the mortar, 16 is first part, 17 is the second part, 18 is the reinforcement.
Example 1: a prefabricated outer wall with a stone-like decorative surface layer comprises a stone-like decorative surface layer 1, a heat insulation layer 2, an inner wall 13, other connecting pieces and sealing materials. The imitation stone decorative surface layer 1 is divided into a smooth surface and a rough surface, can be made into the effects of materials like marble, sandstone and the like, and meets the requirements of different customers on the texture.
The imitation stone decorative surface layer 1 and the heat preservation layer 2 are connected with the inner wall 13 through glass fiber. After the wall board is hoisted and temporarily fixed, the bottom of the wall board is fixedly connected with a third embedded part 11 in the beam 10 through a first embedded part 3, and a second embedded part 14 at the top of the wall board is fixedly connected with the third embedded part 11 in the beam 10 through a connecting plate 12; the first embedded part 3 comprises a first part 16 and an L-shaped second part 17, the first part 16 is fixedly connected with the second part 17, at least one reinforcing part 18 is arranged on the second part 17, the cross section of the reinforcing part 18 is similar to that of a right triangle, a chamfer is arranged between the middle edge and the edge of the right triangle, the first part 16 can increase the anchoring performance of concrete, the second part 17 can enhance the rigidity of the connecting piece, and the chamfer and the protective edge can play a safety role. After the wall boards are connected and fastened one by one, the next wall board is installed until the whole layer is finished. The gap between the wallboard of upper and lower floor is handled, and the 7 shutoff of passing through cement mortar between the lower floor of interior wall 13, the gap between the lower floor of heat preservation 2 is clogged through insulation material rubber and plastic sponge 5, and the gap between the lower floor of imitative stone decorative cover 1 is handled through the 8 shutoff of flexible resistant sealing adhesive. The connecting parts at the inner sides of the rooms are wrapped by decoration.
Example 2: the production and installation process of the prefabricated outer wall is divided into three links:
firstly, the method comprises the following steps: the production process comprises the following steps:
the production process of the stone-like decorative surface layer prefabricated outer wall comprises the following steps: producing a decorative surface layer 1, preparing sand stone materials imitating various stones, uniformly stirring the sand stone materials with cement mortar, pouring the mixture into a wallboard mould, vibrating and trowelling the mixture, placing a surface layer reinforcing mesh sheet after the mortar reaches a certain strength, and pouring concrete; after concrete of the decorative surface layer 1 is poured and leveled, laying an insulating layer 2, after the insulating layer 2 is laid orderly, penetrating glass fiber through the insulating layer 2 and inserting the glass fiber into the concrete of the imitation stone decorative surface layer 1; and placing the steel bars, the first embedded parts 3 and the second embedded parts 14 in the inner wall 13, and pouring the lightweight concrete of the inner wall 13 after all the embedded parts are finished and fixed. After the concrete strength of the whole wall body meets the requirement, demoulding and hoisting are carried out, the stone-like decorative surface layer 1 reaches the effect of customer requirements after being polished or washed, and the whole wallboard production process is completed.
Secondly, the method comprises the following steps: on-site hoisting installation
After the construction of the main structure of the construction site is completed and the floor slab 9 and the concrete of the beam 10 reach the strength, the stone-like prefabricated outer wall is lifted and installed by a special lifting appliance, the wall slab is lifted to the position by a tower crane on the construction site according to the drawing requirements, a constructor aligns the holes in the bottom of the first embedded part 3 of the wall slab to the bolts 11 in advance at the top of the inserted beam 10, meanwhile, the first embedded part 14 at the top of the wall slab is connected with the second embedded part 11 at the bottom of the beam 10 by the connecting plate 12, after all hole sites are aligned, the nuts are screwed to the stability of the wall slab after the steel gaskets are placed, and then the installation of the whole wall slab is completed, and then. The method comprises the following steps of firstly installing an upper layer of wallboard, before the upper layer of wallboard is installed, firstly adhering rubber-plastic sponge 5 to the top of a lower layer of wallboard insulation board 2 according to a construction line, then paving special cement mortar 7 on the top of a lower layer of inner wall 13, and after the paving thickness reaches the drawing requirement, beginning to hoist the upper layer of wallboard at the position. And installing other wallboards according to the requirements until the whole building outer wall is completely installed. Horizontal gaps and vertical gaps between all the outer walls are plugged and blocked by flexible weather-resistant sealant 8.
Thirdly, the method comprises the following steps: and (3) interior decoration treatment:
after the floor board decoration layer 6 is finished, the third embedded parts 11 connected with the first embedded parts 3 are concealed, the middle parts of the vertical abutted seams of the wall boards are filled with rubber and plastic sponge 5, the indoor vertical seam surface layers are filled with caulking mortar 15 to form a dense chamber, and other connecting part parts are concealed after decoration.
