DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present application aims at the technical problems in the prior art that, a secondary masonry process is needed when the construction of the main structure was finished, and thus the construction efficiency is low. Meanwhile, when the construction is finished, a surface of the wall body is uneven, subsequent processes such as puttying may be carried out only after the wall body has been plastered, and thus the construction schedule is affected. Therefore, the present application provides a composite cast-in-situ outer wall, in which case a concrete pouring is implemented by combining an expanding polystyrene board compositing with a cement board or with a calcium silicate board 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.
To make the technical solution and the technical effects more clearly, the present application will be further described with reference to the accompanying drawings and embodiments in the following.
FIG. 1 is an elevation of a composite cast-in-situ outer wall according to a first embodiment of the present application. The composite cast-in-situ outer wall in this case comprises a concrete wall 2 on one side near the outdoor and a composite plate 1 arranged below the hole for doors or windows 3. A hole for windows 3 configured for the mounting of a window on the wall body at a later stage is defined in the middle part of the concrete wall 2. It should be noted that, a thin layer of concrete on the outside of the composite plate 1 is omitted in order to clearly illustrate the location relationships among the composite plate 1, the concrete wall 2 and the hole for windows 3. Actually, the composite plate 1 will not be seen when observing the wall body from outside; only a concrete wall 2 in a shape of a rectangular-ambulatory-plane and the hole for windows 3 in the middle part will be seen. That is, the composite plate 1 is completely or partially embedded into the concrete wall 2. In this embodiment, the composite 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. The two kinds of boards for the composition are capable of providing sufficient strength, and will not be deformed during the installation and using processes. Furthermore, the two kinds of boards are convenient to form a composite plate together with the expanding polystyrene board, and to install, and a wet trade is also possible with these boards. In this embodiment, the composite plate 1 is a plate formed by an expanding polystyrene board compositing with a cement board.
In order to explain clearly how the composite cast-in-situ outer wall according to the embodiment shown in FIG. 1 is constructed, now the embodiment shown in FIG. 1 is further described with reference to FIG. 2. FIG. 2 is a cutaway view along the line A-A of FIG. 1. As shown in FIG. 2, the concrete wall 2, an expanding polystyrene board 11 and a cement board 12 are arranged successively from the outside to the inside. In this case, the expanding polystyrene board 11 and the cement board 12 are composited into an integral composite plate 1 beforehand. The construction method for the composite cast-in-situ outer wall according to a first embodiment of the present application includes the following steps: firstly, the plate formed by the expanding polystyrene board compositing with the cement board is abutted against a template, wherein a shape of the template is in accordance with a shape of the concrete wall 2; then a plurality of wall connections 4 are inserted into the expanding polystyrene board 11; after that, constructed rebar of the concrete wall are bound in the template; the rebar in this case is provided to ensure that the concrete wall 2 constructed later has a sufficient strength; and finally, concrete is poured into the template. After the concrete is dried, the plate formed by the expanding polystyrene board compositing with the cement board is tightly connected to the concrete wall.
Preferably, a cladding 5 as shown in FIG. 3 is further coated at a joint between the composite plate 1 and the concrete wall 2. In this case, the cladding 5 is configured to ensure the tight connection between the composite plate 1 and the concrete wall 2, to avoid problems such as leakage from happening. In this embodiment, the cladding 5 is a three-layer structure, as specifically shown in FIG. 4. FIG. 4 is an enlarged view of a circle region of FIG. 3. The cladding 5 is prepared by the following processes: firstly, a layer of non-shrink mortar is coated at the joint between the composite plate 1 and the concrete wall 2, thereby forming a first non-shrink mortar layer 51; after that, a layer of gridding 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 second non-shrink mortar layer 53.
In the present application, another embodiment of the composite cast-in-situ outer wall is further provided, and the elevation thereof is as shown in FIG. 5. In the second embodiment of the present application, the composite cast-in-situ outer wall also includes a concrete wall 2 on one side near the outdoor, and a composite plate 1 on the other side near the indoor; wherein a hole for windows 3 is defined in the middle part of the concrete wall 2. In the first embodiment, the composite plate 1 is arranged below the hole for windows 3; while in the second embodiment, the composite plate 1 is in a shape of a concave, and the hole for windows 3 is received in the notch of the concave structure. Likewise, in FIG. 5, a thin layer of concrete on the outside of the composite plate 1 is omitted in order to clearly illustrate the location relationships among the composite plate 1, the concrete wall 2 and the hole for windows 3. Actually, the composite plate 1 will not be seen when observing the wall body from outside; only a concrete wall 2 in a shape of a rectangular-ambulatory-plane and the hole for windows in the middle will be seen.
In the first embodiments, the composite plate 1 is an integral hard plate and is in a shape of a rectangle, and a width thereof is equal to a width of the hole for windows 3. However, in the second embodiment, the composite plate 1 is formed by three small hard plates vertically arranged side by side. As shown in FIG. 6, three sub composite plates (101, 102 and 103) are split joint together to form a concave structure, and in this way of splicing, the composite plate 1 is capable of well adapting to the hole for windows of different sizes.
When implementing the second embodiment, in addition to the process of coating the joint between the composite plate 1 and the concrete wall 2 by the means shown in FIG. 3, the joints among the sub composite plates should be coated with cladding likewise. As shown in FIG. 7, at the joint between two adjacent sub composite plates (102 and 103), a cladding 5 is coated at the joint, in order to ensure that the joint will not affect the waterproof performance of the whole outer wall, and further ensure that the adjacent sub composite plates are tightly connected to each other. In the present application, the cladding 5 is a three-layer structure, as shown in FIG. 8. FIG. 8 is an enlarged view of a circle region of FIG. 7. The cladding 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 first non-shrink mortar layer 51; after that, a layer of gridding 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 second non-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, the composite 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.
