Technical Field

[0001] The utility model relates to the technical field of building prefabricated molds, and specifically relates to a building embedded prefabricated mold. Background Art

[0002] In building construction, according to different construction techniques, it is divided into cast-in-place concrete construction and prefabricated construction. During assembly use, various precast concrete components need to be pre-produced and processed into shape. By pre-processing and forming precast concrete components in advance, they can be directly applied during assembly construction. The overall operation is fast, which can greatly reduce the construction time and the generation of garbage and waste during the construction process, speed up the building forming efficiency, and improve the environmental protection of building construction. When pre-producing and processing precast concrete components, in order to well define the size and shape of precast concrete components and avoid non-compliance with production quality requirements, it is necessary to use molds to determine the size of precast concrete components, and bind steel bars and pour concrete raw materials inside them.

[0003] In the prior art, after the embedded prefabricated mold is preformed into a concrete component, it is not convenient to quickly separate the mold from the concrete component, which causes knocking damage to the edge of the concrete component when manually removing the concrete component, affecting its final forming and use. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a building embedded prefabricated mold to solve the technical problem that it is difficult to separate the mold from the formed concrete.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A building embedded prefabricated mold, including a pressing plate, a bottom plate is fixedly connected to the top end of the pressing plate, and the bottom plate is trapezoidal. Fixed columns are welded at the four corners of the pressing plate. Two opening and closing plates are movably connected to both sides of the top of the pressing plate, and two side plates are movably connected to both ends of the pressing plate. Rotating shafts are arranged at the bottom ends of the opening and closing plates and the side plates.

[0006] By adopting the above technical scheme, through the cooperation of the trapezoidal bottom plate fixed to the top of the pressing plate, the fixed columns welded at the four corners of the trapezoidal bottom plate, and the rotating shafts at the bottom ends of the two opening and closing plates and the side plates, the effect of being able to expand in all four directions is achieved. And the design of the opening and closing plates enables the convex plates at the bottom of both sides to lift the already solidified concrete when expanding, realizing rapid demoulding, saving a large amount of manpower, and at the same time enabling the mold to be reused. And through the fixing bolts arranged at the top ends of the four groups of fixed columns and the round holes opened at the tops of the opening and closing plates and the side plates, the effect of fixing the overall structure is achieved.

[0007] Further, both ends of the rotating shaft are movably connected to the fixed column, and both the opening and closing plate and the side plate are rotatably connected to the fixed column through the rotating shaft.

[0008] By adopting the above technical solution, the rotating shaft serves to respectively move the opening and closing plate and the side plate.

[0009] Furthermore, a limiting column is fixedly connected to the top of the fixed column, and the limiting column is in the shape of a cylinder.

[0010] By adopting the above technical solution, the limiting column serves to fix the whole.

[0011] Furthermore, the fixed column respectively passes through a first fixing ring and a second fixing ring, and the first fixing ring and the second fixing ring are rotatably connected to the fixed column.

[0012] By adopting the above technical solution, the fixing ring serves to fix the fixing bolt.

[0013] Furthermore, a first fixing bolt is movably connected to the top of the first fixing ring, and a second fixing bolt is movably connected to the top of the second fixing ring.

[0014] By adopting the above technical solution, the fixing bolt serves to fix the side plate and the opening and closing plate.

[0015] Furthermore, second round holes adapted to the first fixing bolt are provided on both sides of the top end of the side plate, and first round holes adapted to the second fixing bolt are provided on both sides of the top end of the opening and closing plate.

[0016] By adopting the above technical solution, the round hole serves to fix the fixing bolt.

[0017] In summary, the present utility model mainly has the following beneficial effects: By means of the trapezoidal bottom plate fixed to the top of the pressing plate and the fixed columns welded at the four corners of the trapezoidal bottom plate, which cooperate with the rotating shafts at the bottom ends of the two groups of opening and closing plates and side plates, the effect of being able to expand in four directions is achieved. Moreover, the design of the opening and closing plate enables the convex plates at the two bottom sides to lift the already solidified concrete during expansion, realizing rapid demoulding, saving a large amount of manpower, and enabling the secondary use of the mold. At the same time, through the fixing bolts provided at the top ends of the four groups of fixed columns, which cooperate with the round holes provided at the tops of the opening and closing plates and side plates, the effect of fixing the overall structure is achieved.

Install two groups of opening and closing plates 3 and side plates 6 and connect them to the fixed columns 5 through the rotating shafts 4 at their bottom ends so that they can form a closed mold structure;

[0026] Pour concrete into the assembled mold, ensure that the concrete is evenly filled to reach the height required by the design, and perform appropriate vibration and compaction to ensure the density of the concrete;

[0027] During the curing process of the concrete, cooperate with the first fixing bolts 11 and second fixing bolts 12 provided at the top ends of the four groups of fixed columns 5 with the first round holes 7 and second round holes 8 opened at the tops of the opening and closing plates 3 and the side plates 6 to ensure the stability of the overall structure of the mold and prevent deformation caused by external forces during the concrete curing process;

[0028] After the concrete reaches the design strength, first loosen the fixing bolts so that the opening and closing plates 3 and the side plates 6 can move freely. Through the action of the rotating shafts 4, the four sides of the mold will be unfolded. When the mold is unfolded, the raised plates at the bottom of both sides will lift the fixed concrete components to achieve rapid demolding and reduce damage to the surface of the concrete components;

[0029] After demolding, reset the mold again, and fix the opening and closing plates 3 and the side plates 6 again through the rotating shafts and the fixing bolts to prepare for the next concrete pouring. The mold can be used multiple times, improving the construction efficiency and economic benefits.

[0030] Please refer to Figure 3 , both ends of the rotating shaft 4 are movably connected to the fixed column 5, and both the opening and closing plate 3 and the side plate 6 are rotatably connected to the fixed column 5 through the rotating shaft 4. With the above structure of the present utility model, the rotating shaft 4 plays a role in respectively moving the opening and closing plate 3 and the side plate 6.

[0031] Please refer to Figure 1 and Figure 4 , a limiting column 13 is fixedly connected to the top of the fixed column 5, and the limiting column 13 is in the shape of a cylinder. With the above structure of the present utility model, the limiting column 13 plays a role in fixing the whole.

[0032] Please refer to Figures 1-4 , the fixed column 5 respectively penetrates through a first fixing ring 9 and a second fixing ring 10, and the first fixing ring 9 and the second fixing ring 10 are rotatably connected to the fixed column 5. With the above structure of the present utility model, the fixing rings play a role in fixing the fixing bolts.

[0033] Please refer to Figures 1-4 , a first fixing bolt 11 is movably connected to the top of the first fixing ring 9, and a second fixing bolt 12 is movably connected to the top of the second fixing ring 10.

[0035] The working principle of the present utility model is as follows: When in use, place the pressing plate 1 at the construction site and support it through the fixed columns 5 welded at the four corners of the trapezoidal bottom plate 2. Install two groups of opening and closing plates 3 and side plates 6, and connect them to the fixed columns 5 through the rotating shafts 4 at the bottom ends so that they can form a closed mold structure;

[0036] Pour the concrete into the assembled mold, ensure that the concrete is evenly filled, reach the height required by the design, and perform appropriate vibration and compaction to ensure the density of the concrete;

[0037] During the curing process of the concrete, through the first fixing bolts 11 and the second fixing bolts 12 arranged at the top ends of the four groups of fixed columns 5, cooperate with the first round holes 7 and the second round holes 8 opened at the tops of the opening and closing plate 3 and the side plate 6 to ensure the stability of the overall structure of the mold and prevent deformation caused by external forces during the concrete curing process;

[0038] After the concrete reaches the design strength, first loosen the fixing bolts so that the opening and closing plate 3 and the side plate 6 can move freely. Through the action of the rotating shaft 4, the four sides of the mold are unfolded. When the mold is unfolded, the convex plates at the two bottom sides will lift the fixed concrete member, realizing rapid demoulding and reducing damage to the surface of the concrete member;

[0039] After demoulding, reset the mold again, and fix the opening and closing plate 3 and the side plate 6 again through the rotating shaft and the fixing bolts to prepare for the next concrete pouring.
