The wallboard outer mold 5 is used in cooperation with the wallboard inner mold 4, when assembled into a forming model, the wallboard outer mold 5 and the wallboard inner mold 4 are parallel to each other and spaced apart, and the wallboard pouring cavity 6 is formed between the wallboard outer mold 5 and the wallboard inner mold 4. The concrete is poured in the wallboard pouring cavity 6 to form the wall plate 3. The edge of the top plate mold 8 is overlapped on the wallboard inner mold 4, and the wallboard inner mold 4 supports the top plate mold 8. The upper end of the wallboard outer mold 5 has a surrounding edge segment higher than the top plate mold 8, the top plate pouring groove 7 is formed between the top plate mold 8 and the surrounding edge segment, and the top plate pouring groove 7 and the wallboard pouring cavity 6 are in communication with each other. The top plate mold 8 is a removable formwork, and the top plate mold 8 can be borne by conventional cement-based materials such as cement pressure plate or commonly used wood formwork. The top plate mold 8 and the concrete poured on the top plate mold 8 are combined into the roof plate 1, so that the top plate mold 8 only needs to be supported and does not need to be removed, thereby improving the production efficiency of the box house.
[0017] The forming process of the box house comprises the following steps:
[0018] Step S1: preparing the site and materials, laying the steel mesh frame on the site, pouring the concrete on the steel mesh frame to form the floor 2;
[0019] Step S2: installing the inner wall form 4 and the outer wall form 5 on the floor 2 after pouring and forming; the inner wall form 4 and the outer wall form 5 are spliced forms, a plurality of sub-forms are spliced and fixed on the floor 2 to form the inner wall form 4 and the outer wall form 5; the inner wall form 4 and the outer wall form 5 can be aluminum alloy forms, plastic forms, etc.; the inner wall form 4 and the outer wall form 5 form a wall pouring cavity 6 therebetween, and a steel mesh frame is laid in the wall pouring cavity 6;
[0020] In addition, during the installation of the inner wall form 4 and the outer wall form 5, a tensioning piece such as a tensioning bolt needs to be installed between the inner wall form 4 and the outer wall form 5; door and window openings are reserved on the inner wall form 4 and the outer wall form 5, and the reserved door and window openings are supported; and according to needs, corresponding pipelines can be pre-buried in the wall pouring cavity 6;
[0021] Step S3: overlapping the roof form 8 on the inner wall form 4, the roof pouring groove 7 is formed between the roof form 8 and the outer wall form 5, the roof pouring groove 7 and the wall pouring cavity 6 are in communication with each other, and a steel mesh frame is laid in the roof pouring groove 7;
[0022] Step S4: setting up a temporary support rod 9 at the bottom of the roof form 8;
[0023] Step S5: pouring the concrete into the wall pouring cavity 6 and the roof pouring groove 7 at the same time to form the seamless and butt-jointed wall 3 and roof 1;
[0024] Step S6: after the wall 3 and the roof 1 are poured and formed, the inner wall form 4, the outer wall form 5 and the temporary support rod 9 are removed; the roof form 8 is a removable form, which is reserved on the poured and formed roof 1; then the structure of the wall 3 and the roof 1 is rested, and then the interior and exterior decoration is carried out, including heat preservation, heat insulation, pipeline arrangement, etc., to finally obtain the finished prefabricated concrete box house.
[0025] Due to the use of spliced forms, the formwork and form removal do not require large machines and tools, and can be done manually, greatly improving the efficiency; moreover, the size of the prefabricated box house can be changed arbitrarily, and the mold is flexible and convenient to use; in addition, the integrated pouring of concrete can better the overall stiffness and waterproofness of the house; the application of the removable roof form greatly improves the production efficiency; the application of the combined mold makes the production more efficient and the product cost lower, which is convenient for popularization and application.
[0026] As shown in the accompanying drawings Fig. 2As shown in the wallboard, the inner mold 4 of the wallboard is provided with a support plate 10 at the top of the wallboard away from the outer mold 5 of the wallboard. In step S3, when the top plate mold 8 is overlapped on the inner mold 4 of the wallboard, the support plate 10 can assist in supporting the top plate mold 8, so that the top plate mold 8 is more stably overlapped on the inner mold 4 of the wallboard.
[0027] The support plate 10 is detachably mounted on the inner mold 4 of the wallboard, and the support plate 10 is fixed on the inner mold 4 of the wallboard by a detachable pin 11. Specifically, the support plate 10 is a horizontal plate body, and the upper plate surface of the support plate 10 is flush with the top end of the inner mold 4 of the wallboard; a mounting plate 12 is connected below the support plate 10, the mounting plate 12 is a vertical plate body, and the mounting plate 12 is provided with a mounting hole, and the pin 11 is inserted into the inner mold 4 of the wallboard after passing through the mounting hole, so that the support plate 10 is detachably mounted on the inner mold 4 of the wallboard.
[0028] In step S6, the support plate 10 is first removed, so that the support plate 10 no longer supports the top plate mold 8, and then the inner mold 4 of the wallboard is removed. If the support plate 10 is not removed before the inner mold 4 of the wallboard is removed, the support plate 10 is supported on the top plate mold 8, which makes it difficult to remove the inner mold 4 of the wallboard.
[0029] The above is only the preferred embodiment of the present application, it should be pointed out that: for those skilled in the technical field, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application.
