[0029] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme of the present application will be described clearly and completely below in combination with the drawings in the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] The terms "first", "second", "third", etc. are used only for descriptive purposes and should not be construed as implying or suggesting relative importance or an indicated number of technical features. Thus, features defined with "first", "second", etc. can explicitly or implicitly include one or more of the features; in the description of the present application, the meaning of "a plurality" is two or more, unless otherwise stated.

[0031] The inventor of the present utility model finds that in the prior art, the prefabricated concrete unit house forming process adopts the mode of opening a hole at the corresponding position of the inner and outer wall formwork of the prefabricated wall structure mold and edge sealing treatment when processing the door and window hole. This mode can prevent concrete leakage during concrete pouring, but this mode has the problems of time-consuming and laborious formwork erection and demolding when the door and window hole penetrates the inner and outer formwork, and the problem of the need for reordering or modifying the mold when the size and position of the door and window change. Based on this, in the embodiments of the present application provided by the inventor, the prefabricated wall structure mold includes a wall body inner formwork and a wall body outer formwork, and a door hole window mold and a door hole mold are placed at the preset position of the door hole between the wall body inner formwork and the wall body outer formwork. The window mold 3 is clamped by the wall body inner formwork and the wall body outer formwork, which can ensure that the accurate position of the door hole does not enter during concrete pouring. Thus, the problems of time-consuming and laborious formwork erection and demolding when the door and window hole penetrates the wall body inner formwork and the wall body outer formwork can be solved, and the problem of the need for reordering or modifying the mold when the size and position of the door and window change can be solved.

[0032] As shown in Figure 1 The prior art box-type house is composed of four wall panels and a roof panel, also known as a unit house. It includes two side walls located on both sides of the house and a front wall and a rear wall located at the front and rear ends of the house, as well as a roof panel. The door hole and the window hole are arranged on the side wall or the end wall.

[0033] Figures 2-6 A prefabricated unit house general combined mold provided by the embodiments of the present application comprises: a prefabricated top panel structure mold located at the top, a prefabricated front wall structure mold connected to the lower surface of the prefabricated top panel structure and the ground through a connecting structure, a prefabricated rear wall structure mold, and prefabricated side wall structure molds located on the left and right sides of the prefabricated front wall structure mold 1 and the prefabricated rear wall structure.

[0034] The prefabricated front wall structure mold 1, the prefabricated rear wall structure mold, and the prefabricated side wall structure molds on the left and right sides all comprise a wall body inner formwork 1-1 and a wall body outer formwork 1-2; the wall body inner formwork 1-1 is connected to the wall body outer formwork 1-2, and there is a gap between the wall body inner formwork 1-1 and the wall body outer formwork 1-2, and the gap is the preset thickness of the unit house;

[0035] The prefabricated front wall structure mold 1 also includes a door opening mold 2. The door opening mold 2 is fixed at the preset position of the door opening between the inner wall template 1-1 and the outer wall template 1-2. It is clamped by the inner wall template 1-1 and the outer wall template 1-2. The door opening mold 2 does not penetrate the inner wall template 1-1 and the outer wall template 1-2. The thickness of the door opening mold 2 is the preset thickness of the unit room.

[0036] In this embodiment, to assemble a complete unit, precast molds need to be poured in advance, specifically including: a precast front wall structure mold 1, a precast roof slab structure mold, and precast side wall structure molds on the left and right sides. The shapes and sizes of these molds are designed according to specific user requirements, and all can be rectangular. The precast front wall structure mold 1 and the precast rear wall mold are used to pour the front and rear walls, and their specific dimensions can be, for example, a width of 4 meters or 5 meters and a height of 2.4 meters to 3.6 meters. The precast roof slab structure mold is used to pour the roof, and its specific dimensions can be, for example, a length of 4 meters and a width of 5 meters. The precast side wall structure molds on the left and right sides are used to pour the two side walls, and their specific dimensions can be, for example, a width of 2.5 meters or 4 meters and a height of 2.4 meters to 3.6 meters. The precast side wall structure molds on the left and right sides are used to pour the two side walls, and they need to match the precast front wall structure mold 1 and the precast rear wall mold to obtain a complete unit. Doorway mold 2 is used to form the doorway of the unit. Doorway mold 2 is a solid filling block to ensure that the doorway position is not filled with concrete during concrete pouring. Because doorway mold 2 is pre-positioned in the preset position of the doorway, after the doorway mold 2 is removed after the concrete is poured and formed, a doorway will be formed on the front wall of the poured concrete.

[0037] like Figure 2 and Figure 3 As shown, taking the pouring of the front wall as an example, a doorway is provided on the front wall. To form the poured front wall, it is first necessary to fabricate an inner wall template 1-1, an outer wall template 1-2, and a doorway mold 2 that meet the user's requirements. The inner wall template 1-1 and the outer wall template 1-2 are arranged as a single piece, without the need for opening and edge sealing as in existing technologies. The outer wall template 1-1 and the inner wall template 1-2 are made of materials such as steel or aluminum alloy, and their thickness varies depending on the size of the mold, the forming pressure, and the complexity of the parts. Then, the doorway mold 2 is fabricated, which can be made of materials such as lightweight foam board, extruded polystyrene board, or wood. In one possible embodiment, the shape of the doorway mold 2 can be rectangular, circular, or arc-shaped. Optionally, the size and shape of the doorway can be customized according to the user's requirements. After the inner wall template 1-1, the outer wall template 1-2, and the doorway mold 2 are fabricated, the mold can be deployed to prepare for pouring.

[0038] When pouring, first arrange the wall inner formwork 1-1, then paste the door hole mold 2 at the preset position of the door hole of the wall inner formwork 1-1, then arrange the wall outer formwork 1-2, and the gap between the wall inner formwork 1-1 and the wall outer formwork 1-2 is the preset thickness of the unit house. As shown in Figure 4 , the solid filling block of the door hole mold 2 is clamped by the wall inner formwork 1-1 and the wall outer formwork 1-2 and does not penetrate the wall inner formwork and the wall outer formwork 1-2, so there is no problem of time-consuming and laborious stripping. After pouring and curing, the formwork needs to be removed, the wall outer formwork 1-2 can be removed first, then the door hole mold 2 and the wall inner formwork are removed. At this time, the front wall of a unit house is poured and formed, and can be delivered or constructed. By using the above method, the door hole mold 2 can be moved and the size can be modified according to the design of the unit house and the needs of the user, so it is not necessary to repeatedly customize and modify the prefabricated front wall structure mold 1. The construction difficulty is reduced, and the construction cost is solved.

[0039] The rear wall, the two side walls and the layer top plate can be poured by using the above method, and the door hole mold 2 is determined according to the needs during pouring of the rear wall and the two side walls. After all pouring is completed, a unit house structure as shown in Figure 1 can be assembled.

[0040] By using the above technical scheme, the door hole mold 2 is fixed between the wall inner and outer formworks in advance, without the need for cutting or reserving later, and is tightly matched with the inner and outer formworks, so as to ensure the accuracy of the door hole position and size, simplify the construction process and improve the construction quality. Moreover, the door hole mold 2 can be moved and the size can be modified according to the design of the unit house, so as to adapt to more diversified unit house structure designs.

[0041] In a possible implementation, as shown in Figure 2 and Figure 6 , the door hole mold 2 further includes a construction passage mold 4, the construction passage mold 4 penetrates the wall inner formwork 1-1 and the wall outer formwork 1-2, the construction passage mold 4 includes a top frame 4-1 and two side frames 4-2, the top frame 4-1 and the side frames 4-2 are connected with the edges of the wall inner and outer formworks, and the length and height of the construction passage mold 4 are less than those of the door hole.

[0042] In the embodiment of the present application, in order to ensure convenient construction, a small rectangular passage can be formed on the door hole mold 2. Since the construction passage mold 4 penetrates the inner wall formwork 1-1 and the outer wall formwork 1-2, a rectangular passage with the size of the construction passage mold 4 needs to be formed on the inner wall formwork 1-1 and the outer wall formwork 1-2. A top frame 4-1 and a side frame 4-2 are installed around the passage. During construction, workers can enter the interior of the wall through the small passage to bind steel bars and detect. After pouring and removing the outer formwork, the workers can enter the interior of the wall through the construction passage mold 4 to remove the inner wall formwork 1-1. The construction passage mold 4 is only a temporary opening relative to the final door hole and does not affect the normal use and size of the door hole. Although the embodiment also forms a hole on the inner wall formwork 1-1 and the outer wall formwork 1-2, the hole is smaller than the hole in the prior art and is arranged at the position of the door hole mold 2, which does not affect the integrity of the inner wall formwork 1-1 and the outer wall formwork 1-2.

[0043] In a possible implementation, as shown in Figure 2 and Figure 5 , the prefabricated front wall structure mold 1 includes a window mold 3 arranged at a preset position of a window between the inner wall formwork 1-1 and the outer wall formwork 1-2, clamped by the inner wall formwork 1-1 and the outer wall formwork 1-2, and having a thickness of a preset thickness of the unit house.

[0044] By using the above technical solution, the window mold 3 is used to form a window hole of the unit house, and the arrangement manner is similar to that of the door hole mold 2, which will not be described in detail here. The window mold 3 can be arranged on the front wall. The window mold 3 eliminates the difficulty of opening a window at a later stage, improves the overall efficiency and precision of prefabrication and construction, ensures the accuracy of the position and size of the window, and does not need to be cut or processed again. In a possible implementation, the window mold 3 has one of a rectangular shape, a circular shape, and an arc shape. Optionally, the size and shape of the door hole can be customized according to user requirements.

[0045] In a possible implementation, the side of the inner wall formwork 1-1 away from the outer wall formwork 1-2 is provided with a support device, and the side of the outer wall formwork 1-2 away from the inner wall formwork 1-1 is also provided with a support device. The support device includes a formwork back ridge 1-4 and an inclined support strip 1-5. The formwork back ridge 1-4 is distributed along the long side of the outer wall formwork 1-2 or the inner wall formwork 1-1. One end of the inclined support strip 1-5 is connected with the outer wall formwork 1-2 or the inner wall formwork 1-1, and the other end of the support strip is connected with the ground.

[0046] By adopting the above technical solution, the combination of the template back lath 1-4 and the inclined support strip 1-5 can effectively improve the rigidity and stability of the template, and ensure that the template is not easy to deform or shift during pouring of concrete. The back lath is distributed on the long side of the template, which helps to uniformly distribute the stress, and the inclined support transmits the stress to the ground, improving the overall support strength. The template back lath 1-4 and the inclined support strip 1-5 help to maintain the dimensional accuracy of the wall during pouring of concrete and improve the final forming quality.

[0047] In a possible implementation, a template tie member 1-3 is arranged between the inner wall template 1-1 and the outer wall template 1-2. In a possible implementation, the template tie member 1-3 is a tension bolt or a pull tab.

[0048] By adopting the above technical solution, the template tie member 1-3 is used to firmly connect the inner wall template 1-1 and the outer wall template 1-2, and maintain the distance between the templates, thereby ensuring the accuracy of the wall thickness. At the same time, it can reduce the risk of template side shift and deformation, making the poured wall surface more flat and deviation-free.

[0049] In a possible implementation, the door hole mold 2 can also be arranged on the prefabricated rear wall structure mold and the prefabricated side wall structure molds on the left and right sides. In a possible implementation, the window mold 3 can also be arranged on the prefabricated rear wall structure mold and the prefabricated side wall structure molds on the left and right sides.

[0050] The application range of the door hole mold 2 and the window mold 3 is extended to other walls except the front wall, such as the rear wall and the side wall, which improves the applicability and flexibility of the universal combined mold. It provides convenience for different building layouts and meets the design needs of multi-unit, multi-direction prefabricated unit houses.

[0051] Working principle: taking the pouring of the front wall as an example, according to the thickness of the wallboard and the top plate, the position of the door and window, etc. to design the mold, set the door hole and window in the front wall. To form the poured front wall, the wall inner formwork 1-1, the wall outer formwork 1-2, the door hole mold 2 and the window mold 3 are needed. The wall inner formwork 1-1 and the wall outer formwork 1-2 are arranged in one piece, without the need to open a hole and seal the edge as in the prior art. First, support the wall inner formwork 1-1, then paste the door hole mold 2 at the preset position of the door hole of the wall inner formwork 1-1, and paste the window mold 3 at the preset position of the window of the wall inner formwork 1-1. In addition, the door hole mold 2 needs to be arranged at the position of the construction access mold 4, and then the wall outer formwork 1-2 is arranged, the gap between the wall inner formwork 1-1 and the wall outer formwork 1-2 is the preset thickness of the unit house. The formwork tie 1-3 is arranged between the wall inner formwork 1-1 and the wall outer formwork 1-2 to firmly connect the wall inner formwork 1-1 and the wall outer formwork 1-2. The support device needs to be arranged on the side of the wall inner formwork 1-1 and the wall outer formwork 1-2 to ensure that the formwork is not easily deformed or displaced during pouring of the concrete. After the arrangement is completed, pour the concrete from above the front wall, and use the vibrating rod to stir the concrete during pouring to make the concrete fill the gap. After pouring is completed, wait for molding. After molding, the formwork is removed, the wall outer formwork 1-2 is removed first, then the wall inner formwork 1-1 is removed through the construction access mold 4, and then the door hole mold 2 and the window mold 3 are removed in turn.
