In existing technologies, there is limited room for improvement in the connection strength between precast components, especially due to the lack of special construction in the cast-in-place cavity, which leads to insufficient connection strength between upper and lower precast components.
Corrugated pipes are installed inside the precast components, and the corrugated pipes are embedded in the inner wall of the main body of the components. A cast-in-place cavity is constructed at the bottom. The concave and convex structure of the corrugated pipes enhances the bonding area of the cast-in-place concrete. At the same time, the upper and lower layers of precast components are connected by reinforcing bars inserted later, avoiding the traditional module dismantling steps.
It improves the connection strength and manufacturing efficiency of precast components, increases the bonding area of cast-in-place concrete, and simplifies the manufacturing process of precast components.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated component manufacturing technology, and in particular to a prefabricated component, a prefabricated component mold, and a connection structure for the prefabricated component. Background Technology
[0002] The method for manufacturing precast components involves first setting up a mold frame in a factory, then placing modules within the mold frame to create a cavity structure corresponding to the shape of the modules. Concrete is then poured into the mold, and after the concrete has solidified, the mold is removed to obtain the precast component.
[0003] In related technologies, in order to enhance the connection strength between the upper and lower precast components, a cast-in-place cavity is often constructed at the bottom of the precast component using modules. However, due to the lack of special construction of the cast-in-place cavity, there is still room for improvement in the strength of the connection between the upper and lower precast components.
[0004] Therefore, this utility model is proposed. Utility Model Content
[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a precast component, a precast component mold, and a connection structure for the precast component, so as to solve the technical problems in the related technologies.
[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:
[0007] This utility model provides a precast component, which includes a component body. The component body has a concrete pouring channel inside and is provided with a corrugated pipe for constructing a pouring cavity. The corrugated pipe is fitted into the inner wall of the component body. The upper end of the concrete pouring channel is connected to the top of the component body, the lower end is connected to the top of the corrugated pipe, and the bottom end of the corrugated pipe is connected to the bottom of the component body.
[0008] This utility model also provides a precast component mold for making the above-mentioned precast components. The precast component mold includes: a mold frame consisting of at least two side molds and a bottom mold located at the bottom of the side molds. A concrete pouring channel module and the corrugated pipe are provided in the mold frame. The bottom end of the concrete pouring channel module is connected to the top end of the corrugated pipe, and the bottom end of the corrugated pipe is connected to the bottom mold.
[0009] Optionally, the bottom mold is provided with a flange for positioning and fixing the bellows, and the flange is connected to the bottom of the bellows.
[0010] Optionally, a through-beam notch is constructed on the side mold along the thickness direction of the precast component to be manufactured, so that the horizontal reinforcing bars of the precast component can be inserted into the notch along the thickness direction of the precast component.
[0011] Optionally, the inner side of the side mold is provided with an edge cavity module for constructing the edge cavity of the precast component, and the outer side of the edge cavity module is the horizontal steel bar of the precast component.
[0012] Optionally, the side mold has a boss on one side edge in the thickness direction of the precast component mold, and the inner side of the boss fits into the edge cavity module.
[0013] Optionally, the horizontal reinforcement includes ring-shaped reinforcement disposed near the edge of the precast component or ring-shaped reinforcement extending from one side of the component body to the other side.
[0014] This utility model also provides a connection structure for precast components, including an upper precast component and a lower precast component. Both the upper and lower precast components are the aforementioned precast components. The lower precast component has a concrete pouring channel and a corrugated pipe with a rear-inserted steel bar inside. The top end of the rear-inserted steel bar extends into the cast-in-place cavity formed by the corrugated pipe at the bottom of the upper precast component.
[0015] This utility model provides a connection structure for precast components. A corrugated pipe is set at the bottom of the precast component and is embedded in the main body of the component, so that the corrugated pipe structure has a casting cavity. At the same time, since the surface of the corrugated pipe has a concave-convex structure, it can enhance the bonding area of the cast-in-place concrete and improve the anchoring strength by means of this embedded structure. In addition, since the corrugated pipe is embedded in the main body of the precast component, it does not need to be removed like other traditional modules, thus improving the production efficiency of precast components.

Detailed Implementation
[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0028] The present invention provides a precast component, which includes a component body 1. The component body 1 has a concrete pouring channel 2 inside and is provided with a corrugated pipe 3 for constructing a pouring cavity. The corrugated pipe 3 is fitted into the inner wall of the component body 1. The upper end of the concrete pouring channel 2 is connected to the top of the component body 1, the lower end is connected to the top of the corrugated pipe 3, and the bottom end of the corrugated pipe 3 is connected to the bottom of the component body 1.
[0029] This utility model also provides a precast component mold for manufacturing the aforementioned precast components. The precast component mold includes a mold frame consisting of at least two side molds 4 and a bottom mold 5 located at the bottom of the side molds 4. Of course, a top mold can also be provided depending on the specific situation. A concrete pouring channel module 6 and a corrugated pipe 3 are provided within the mold frame. The concrete pouring channel module 6 forms a concrete pouring channel 2, and its bottom end is connected to the top end of the corrugated pipe 3. The bottom end of the corrugated pipe 3 is connected to the bottom mold. The surface of the corrugated pipe 3 has an uneven structure, forming a corrugated structure. After manufacturing, it will fit into the inner wall of the component body 1. The corrugated structure effectively increases the bonding area between the cast-in-place concrete and the component body 1, thereby improving the connection strength when connecting the upper and lower layers of precast components.
[0030] In this embodiment, the bottom mold 5 is provided with a flange 9 for positioning and fixing the bellows 3. The flange 9 is connected to the bottom of the bellows 3, which serves to position and fix the bellows 3.
[0031] A through-beam notch 8 is constructed on the side formwork 4 along the thickness direction of the precast component to be manufactured, allowing the horizontal reinforcing bars 7 of the precast component to be inserted into the notch 8 along the thickness direction of the precast component. Since the horizontal reinforcing bars 7 need to be inserted into the mold frame, the notch 8 ensures that the side formwork does not obstruct the insertion of the horizontal reinforcing bars 7. During demolding, the side formwork 4 can also be removed along the thickness direction of the precast component without being obstructed by the horizontal reinforcing bars 7.
[0032] The inner side of the side mold 4 is provided with an edge cavity module 11 for constructing the edge cavity 10 of the precast component, and the outer side of the edge cavity module 11 is the horizontal reinforcing bar 7 of the precast component. During demolding, the edge cavity module 11 can be pulled out vertically. In this embodiment, the edge cavity module 11 is a wedge-shaped structure that is narrow on the inside and wide on the outside.
[0033] Furthermore, the side mold 4 has a boss 12 on one side edge in the thickness direction of the precast component mold, and the inner side of the boss 12 fits against the edge cavity module 11. Since there is a certain distance between one side of the horizontal steel bar 7 and the edge cavity module 11 at this time, the boss 12 can stabilize and position the edge cavity module 11, preventing the edge cavity module 11 from shifting during the casting process of the mold, thereby ensuring that the position and shape of the edge cavity of the structure meet the predetermined requirements.
[0034] The horizontal reinforcing bars 7 include ring-shaped reinforcing bars located near the edge of the precast component, typically in cases where a window 16 exists in the center. Alternatively, they can be ring-shaped reinforcing bars extending from one side of the main body 1 to the other. As described in the previous embodiment, since the side formwork 4 has reinforcing bar notches 8, the ring-shaped reinforcing bars can be inserted along the thickness direction. Therefore, whether it is a horizontal reinforcing bar 7 running horizontally or a ring-shaped reinforcing bar located at the edge, the insertion of the reinforcing bars can be smoothly achieved.
[0035] This utility model also provides a connection structure for prefabricated components, including an upper prefabricated component 14 and a lower prefabricated component 15. Both the upper prefabricated component 14 and the lower prefabricated component 15 are the aforementioned prefabricated components. The lower prefabricated component 15 has a rear-inserted steel bar 13 installed in the concrete pouring channel 2 and the corrugated pipe 3. The top end of the rear-inserted steel bar 13 extends into the cast-in-place cavity formed by the corrugated pipe 3 at the bottom of the upper prefabricated component 14.
[0036] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
