[0002] In recent years, in order to alleviate the problems of labor shortage, short construction period, low carbon and environmental protection, China has begun to promote fabricated buildings. As a new green and energy-saving building, it has the advantages of fast construction speed, less influence of climate conditions, saving of on-site labor, and improvement of building quality, and has become a new direction for the development of the future building industry.

[0004] The fabricated composite shear wall is usually composed of two layers of prefabricated reinforced concrete plates connected by trusses or connecting pieces to form a wall plate component with an intermediate cavity. After being installed on site, the intermediate cavity is filled with concrete to form a concrete wall plate. The current fabricated composite shear wall has been applied to engineering. Compared with the full-precast concrete shear wall, the fabricated composite shear wall has the advantages of small weight, low processing and installation precision, strong fault tolerance, and is a promising fabricated concrete structure system.

[0005] The prefabricated concrete formwork is an important component of the fabricated composite shear wall. In the production process of the prefabricated concrete formwork, an intermediate cavity needs to be formed, which requires the use of a core mold component. Currently, there are problems such as complicated steps and low production efficiency in the production process of the prefabricated concrete formwork. In addition, in the construction and application of the fabricated composite shear wall, there are also problems such as difficulty in guaranteeing the quality of steel bar connection, difficulty in concrete pouring and vibration, and difficulty in overlapping stress of prefabricated concrete formwork and cast-in-place concrete, which is not conducive to the normal development of the construction period and poses a hidden danger to the safety of the structure.

[0063] As shown in Figure 1 and Figure 2 , the snap structure 30 comprises a groove 31 arranged on the outer side of the end of the third side plate 21 and the fourth side plate 22 and a protrusion 32 arranged on the inner side of the end of the first side plate 11 and the second side plate 12, the protrusion 32 can be embedded in the corresponding groove 31 to form clamping, and the protrusion 32 is in the shape of a semispherical curved surface, which is convenient for guiding sliding into the groove 31; the groove 31 and the protrusion 32 of the snap structure 30 are designed so that the first core mold assembly 10 and the second core mold assembly 20 can be tightly connected, which guarantees the integrity and stability of the core mold part and avoids dislocation or falling off during pouring. In addition, this clamping mode is convenient for assembling and disassembling the core mold part, improves the reusability of the core mold part and reduces the production cost of the prefabricated concrete formwork.

[0064] As shown in Figure 1 and Figure 2As shown, the first side plate 11 and the second side plate 12 are further provided with a support rib 17, which enhances the stability between the first side plate 11 and the second side plate 12, improves the overall rigidity of the core mold component, avoids deformation of the first side plate 11 and the second side plate 12 due to external force during pouring, and ensures the accurate shaping of the prefabricated concrete formwork.

In addition, the slot width design of the first clamping groove 25, the second clamping groove 15 and the third clamping groove 18 further enhances the locking effect of the first force holding rod 26, the second force holding rod 16 and the force releasing rod 19, ensures that the core mold component can still maintain good structural integrity when subjected to external force, and improves the production quality and efficiency of the prefabricated concrete formwork.

For example, it can be 10 mm. In this way, the support rib 17 can be appropriately deformed when subjected to external force, thereby ensuring that the snap structure 30 is smoothly separated during the demolding of the core mold component, avoiding that the insufficient deformation of the support rib 17 due to too small spacing affects the demolding effect, and also preventing that the support rib 17 has insufficient supporting force due to too large spacing, thereby affecting the overall stability of the core mold component. The first force holding rod 26, the second force holding rod 16 and the force rod 19 are all rigid rod members, which can be made of metal such as stainless steel, and each rod member and the corresponding mounting groove can be mounted in a screw-in or push-in manner.

[0067] The third side plate 21 and the fourth side plate 22 in the present application can be made of elastic material, including but not limited to organic non-metallic material.

[0068] The implementation principle is as follows: the core mold component in the present application is divided into a first core mold assembly 10 and a second core mold assembly 20 according to the structural difference, and the first force holding rod 26 capable of applying pressure is arranged on the second core mold assembly 20. When in use, the first force holding rod 26 on the second core mold assembly 20 is subjected to pressure so that the third side plate 21 and the fourth side plate 22 are deformed to approach each other, thereby enabling the first core mold assembly 10 and the second core mold assembly 20 to be embedded and combined with each other, and a snap connection is formed through the snap structure 30, and the first core mold assembly 10 and the second core mold assembly 20 form the core mold component.

[0069] Referring to Figure 4 As shown, the core mold component in the present application can be cooperated by using a rotating shaft mechanism 60, which includes a rotating shaft part 61 and two interval arranged rotating mold parts 62. The two rotating mold parts 62 are symmetrically arranged on the two sides of the rotating shaft part 61, and the two rotating mold parts 62 are rotationally connected to the rotating shaft part 61 through connecting rods 63. The included angle between the two connecting rods 63 is less than 180 degrees. The rotating shaft part 61 is structurally matched with the force rod 19, and the rotating shaft part 61 can be sleeved on the force rod 19. The rotating mold part 62 is structurally matched with the second force holding rod 16, and the two rotating mold parts 62 can be respectively sleeved on the two second force holding rods 16, and the rotating mold part 62 and the rotating shaft part 61 can rotate by themselves.

[0070] Combination Figure 1 and Figure 2 As shown, the rotating shaft mechanism 60 is installed on the corresponding second force-bearing rod 16 and driven rod 19 in the first core mold assembly 10. At the same time, pressure is applied to the first force-bearing rod 26 on the second core mold assembly 20 and the rotating shaft mechanism 60 on the first core mold assembly 10. A pair of grooves 31 in the snap fastener structure 30 are displaced inward, and a pair of protrusions 32 in the snap fastener structure 30 are displaced outward. The snap fastener structure 30 can be detached, thereby achieving separation and pull-out from the mold shell to form a vertical hole.

[0071] The core mold component in this application enables convenient assembly and disassembly of the first core mold assembly 10 and the second core mold assembly 20, effectively realizing the hole-forming process of precast concrete mold shells, improving the production and demolding efficiency of precast concrete mold shells, increasing the production efficiency of precast concrete mold shells, reducing the production cost of precast concrete mold shells, and ensuring the molding quality and structural stability of precast concrete mold shells.

[0072] Example 2

[0073] Reference Figure 5 , Figure 6 and Figure 7 As shown, this embodiment is largely the same as Embodiment 1, except that the outer circumferential surfaces of the first arc-shaped end plate 13 and the second arc-shaped end plate 23 in this embodiment have protrusions 40; the slope of one side of the protrusion 40 is greater than the slope of the other side. The protrusions 40 allow the precast concrete formwork to better contact the cast-in-place concrete during concrete pouring, enhancing the stability and reliability of the entire composite shear wall. The greater slope of one side of the protrusion 40 makes it easier to pull the core mold components out of the concrete during removal, reducing resistance during removal and improving work efficiency.
