Description

Technical Field

[0001] This utility model relates to the field of building structure technology, specifically a precast hole perforation structure for precast concrete walls. Background Technology

[0002] Precast concrete components are a process of prefabricating concrete parts for buildings or structures in a factory or on-site. Using precast concrete components for assembly construction has advantages such as saving labor, overcoming seasonal influences, and facilitating year-round construction. Promoting the use of precast concrete components is one of the important ways to realize the industrialization of construction. During the production of precast concrete walls, holes need to be drilled.

[0003] Current methods for creating holes typically involve pre-embedding circular pipes during wall pouring. However, once the concrete has solidified, these pipes cannot be removed, which not only affects the quality of the precast concrete wall but also poses certain safety hazards later on. Therefore, those skilled in the art have provided a perforated structure for precast holes in precast concrete walls to solve the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this utility model is to provide a precast hole perforation structure for precast concrete walls to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A precast hole perforation structure for a precast concrete wall includes a baffle, a positioning tube installed on the outer surface of the baffle, a positioning rod threadedly connected to the inner wall of the positioning tube, a circular plate installed on the outer surface of the positioning rod, a rubber ring sleeved on the outside of the positioning tube, and handles arranged in a ring on the outer surface of the circular plate.

[0007] As a further improvement of this utility model: an anti-slip pad is installed on the outer surface of the baffle, and the anti-slip pad has anti-slip texture on its outer surface.

[0008] As a further improvement of this utility model: the inner wall of the positioning tube is provided with internal threads, and the outer surface of the positioning rod is provided with external threads.

[0009] As a further improvement of this utility model: a sealing gasket is snapped onto the bottom surface of the circular plate, and a groove is installed on the outer surface of the sealing gasket.

[0010] As a further improvement of this utility model: a locking block is installed on the outer surface of the circular plate, and the locking block is adapted to the locking slot.

[0011] As a further improvement of this utility model: the outer surface of the positioning tube is connected to a lubricating layer, which is a lubricating paint surface.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This precast hole perforation structure for precast concrete walls, through the cooperation of positioning tubes, positioning rods, rubber rings, circular plates, handles, internal threads, and external threads, allows for the installation and removal of the rubber rings, making the precast hole operation for precast concrete walls more convenient. The design of slots, blocks, and sealing gaskets not only allows for the installation and removal of the sealing gaskets but also improves the sealing effect of the equipment. The lubrication layer facilitates the removal of the rubber rings, resulting in higher quality precast holes for precast concrete walls. Attached Figure Description

[0020] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figures 1-5 In this embodiment of the present invention, a precast hole perforation structure for a precast concrete wall includes a baffle 1, a positioning tube 2 installed on the outer surface of the baffle 1, a positioning rod 3 threadedly connected to the inner wall of the positioning tube 2, a circular plate 4 installed on the outer surface of the positioning rod 3, a rubber ring 5 sleeved on the outside of the positioning tube 2, and a ring-shaped handle 6 installed on the outer surface of the circular plate 4, which facilitates the removal of the rubber ring 5. This improves the efficiency of precast hole production in precast concrete walls and solves the problem mentioned in the background art that the current hole-making method usually involves pre-embedding a circular tube during wall pouring, but after the concrete is formed, the circular tube cannot be removed, which not only affects the quality of the precast concrete wall but also poses certain safety hazards in the later stages.

[0023] The outer surface of the baffle 1 is equipped with an anti-slip pad 9, and the outer surface of the anti-slip pad 9 is provided with anti-slip texture 13. The inner wall of the positioning tube 2 is provided with an internal thread 7, and the outer surface of the positioning rod 3 is provided with an external thread 8. This not only makes the equipment more stable, but also allows people to disassemble and assemble the positioning tube 2, thus making it convenient for people to remove the rubber ring 5.

[0024] A sealing gasket 10 is snapped onto the bottom surface of the circular plate 4. A slot 11 is installed on the outer surface of the sealing gasket 10. A locking block 12 is installed on the outer surface of the circular plate 4. The locking block 12 is adapted to the slot 11. A lubricating layer 14 is connected to the outer surface of the positioning tube 2. The lubricating layer 14 is a lubricating paint surface, which can prevent the precast concrete wall from entering between the positioning tube 2 and the rubber ring 5 during the pouring process, thereby affecting people's removal of the rubber ring 5.

[0025] The working principle of this utility model is as follows: First, the rubber ring 5 can be fitted onto the outside of the positioning tube 2. Then, the sealing gasket 10 can be installed using the slot 11 and the block 12. Then, the positioning rod 3 can be rotated using the handle 6. The connection between the positioning rod 3 and the positioning tube 2 is completed by the cooperation of the internal thread 7 and the external thread 8. The setting of the lubrication layer 14 can prevent the rubber ring 5 from being unable to be removed after the precast concrete wall is formed. The setting of the sealing gasket 10 can prevent concrete from entering between the positioning tube 2 and the rubber ring 5 during the pouring process of the precast concrete wall, thereby affecting the removal of the rubber ring 5.
