Thecladding 5 is prepared with the following processes: firstly, a layer of non-shrink mortar is coated at the joint between two sub composite plates (102 and 103), thereby forming a firstnon-shrink mortar layer 51; after that, a layer ofgridding cloth 52 is covered on the non-shrink mortar; and finally, an additional layer of non-shrink mortar is further coated on the gridding cloth, thereby forming a secondnon-shrink mortar layer 53. Compared with the preparation processes of the cladding in the first embodiment, it can be understood that, the preparation processes of the cladding at all the joints are the same in the present application. In practical operation, the constructor may firstly coat a layer of non-shrink mortar at all of the joints, then correspondingly cover a layer of gridding cloth on the mortar, and finally coat an additional layer of non-shrink mortar on all of the gridding cloth. - The differences between the two embodiments provided in the present application lie in that, the composite plates and the shapes of the hole for windows are different. It should be understood for one skilled in the art that, all belong to the protection scope of the present application, as long as the construction method for the outer wall is achieved by using a composite plate and pouring the concrete for one time.
- The processes for constructing the outer wall of the present application corresponding to the two embodiments described above are shown in
FIG. 9 . Firstly, in step S1, the composite plate is abutted against the hollow template, wherein the template has two side plates respectively in shapes of rectangular-ambulatory-planes opposite to each other, that is, each of the side plates has a through-hole defined therein. And the composite plate is positioned below the through-hole. When the composite plate is mounted in the template, the composite plate is abutted against one side plate of the template, and is separated from the other side plate of the template. In this way, it can be ensured that an integrated concrete surface is formed on one side near the outdoor during a subsequent concrete pouring process. Preferably, thecomposite plate 1 is a plate formed by an expanding polystyrene board compositing with a cement board, or a plate formed by an expanding polystyrene board compositing with a calcium silicate board. - When the composite plate was mounted to the template based on the above step, a step S2 is implemented. A plurality of
wall connections 4 are inserted into the composite plate from the side plate thereof near the template, wherein each wall connection is inserted into the composite plate in some sections, and the other sections of the wall connection extend out into the inner space of the template. - After that, a step S3 is implemented. Constructed rebar is bound in the interior of the hollow template. When concrete is poured at a later stage, the rebar and the concrete together form a reinforced concrete structure, which enhances the strength of the wall body.
- When the above step has been finished, in a step S4, the concrete allocated is poured into the interior of the template, such that the inner space of the template is completely filled with the concrete. Then, waiting for a period of time until the concrete is dried and hardened; in this way, a wall body is formed.
- After the concrete is hardened, the concrete and the composite plate are integrated with each other, and the wall connections further enhance the connection force between the concrete and the composite plate, ensuring that the composite plate will not fall off from the concrete wall. At this time, the template is removed, and then a step S5 is implemented. In step S5, all of the joints are coated in order to form claddings. For example, the claddings are coated at the joints between the composite plate and the concrete, or the joints between individual sub composite plates forming the integral complete composite plate, etc. The cladding is achieved by firstly coating a layer of non-shrink mortar, then correspondingly covering a layer of gridding cloth, and finally coating an additional layer of non-shrink mortar on all of the gridding cloth.
- When the above steps have been finished, the construction of the wall body structure is completed. Since the evenness of the surface of the wall body is controlled by the template, there is no need to carry out any puttying process, or to use the blocks to build the wall. In this way, the amount of work in construction is greatly reduced, and the construction efficiency is improved.
- When implementing the composite cast-in-situ outer wall and construction method thereof, the outer wall is constructed by using an expanding polystyrene board compositing with a cement board or a calcium silicate board, together with a concrete wall; a concrete pouring is implemented along with the wall body connected thereto. In this way, a one-time integral pouring is achieved; meanwhile, it is ensured that the surface of the wall is even, and thus the construction efficiency and construction quality are improved.
- The description above is just the specific embodiments of the present application, and not for limitation. Any well known modifications or equivalent replacements made by one skilled in the art belong to the protection scope of the present application should be protected.
