Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of building construction, specifically to a pipe connection component for grouting in building construction. Background Technology
[0002] In the field of building construction, grouting is an indispensable and crucial process, widely used in foundation reinforcement, structural crack repair, and waterproofing of underground engineering projects. The core of grouting lies in using a grouting pump to precisely inject a specifically proportioned grout under pressure into voids, cracks, and areas requiring reinforcement within the building's foundation or structure. This process not only effectively fills voids, enhancing the structure's integrity and stability, but also improves the building's load-bearing capacity and durability to a certain extent, thus ensuring the building's safe use.
[0003] However, existing pipe connection components for grouting have many shortcomings in practical applications. Especially when connecting grouting hoses, the flexible material of the hoses and the possibility that the hose opening size is smaller than the connecting pipe make the connection process difficult, hindering quick and stable connections. Furthermore, traditional connection components often involve complex operations when expanding the hose to fit the connecting pipe, easily damaging the hose and affecting the smooth progress of grouting operations. Therefore, developing a new type of pipe connection component for grouting in building construction to solve these problems in the existing technology is particularly urgent and necessary. Utility Model Content
[0004] The purpose of this utility model is to provide a pipe connection component for grouting in building construction, so as to solve the above-mentioned shortcomings in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe connection component for grouting in building construction, comprising a grouting hose and a connecting pipe, characterized in that an outer sleeve is threaded on the outer surface of the connecting pipe, and multiple expansion plates are installed on the outer sleeve through an expansion mechanism, and the expansion mechanism is connected to the connecting pipe through a telescopic rod, wherein the expansion mechanism expands the multiple expansion plates outward while also moving the connecting pipe toward the expansion plates through the telescopic rod.
[0006] As a further description of the above technical solution: the expansion mechanism includes a drive disc movably mounted on the outer tube sleeve, and the drive disc has multiple sets of curved grooves arranged in a circumferential array. The end of the expansion plate is slidably fitted into the curved grooves and the limiting groove, and the limiting groove is fixed on the outer tube sleeve.
[0007] As a further description of the above technical solution: all of the expansion plates are configured as arc-shaped, and when the expansion plates expand outward and come into contact with the inner wall of the grouting hose, the arc-shaped outer surface of the expansion plate is in contact with the inner wall of the grouting hose.
[0008] As a further description of the above technical solution: the outer tube sleeve surface is also threaded with a threaded nut block, and a connecting groove is opened on some surfaces of the drive disk near the threaded nut block. A traction column with one end movably connected to the surface of the threaded nut block is slidably fitted in the connecting groove.
[0009] As a further description of the above technical solution: the surface of the expansion plate that is in contact with the inner wall of the grouting hose is coated with wear-resistant lubricating grease.
[0010] As a further description of the above technical solution: when the wire block is rotated so that it moves to its maximum stroke via the traction drive disc, the expansion plate separates from the grouting hose.
[0011] In the above technical solution, the pipeline connection component for grouting in building construction provided by this utility model has the following beneficial effects:
[0012] 1. Improved installation convenience: The expansion mechanism causes multiple expansion plates to expand outward, while simultaneously moving the connecting pipes towards the expansion plates. This expands the opening of the grouting hose, making it easier to connect to the connecting pipes and significantly improving the ease of installation of the grouting hose.
[0013] 2. Enhanced fit: The expansion plate is designed in an arc shape, and its arc-shaped outer surface fits against the inner wall of the grouting hose. This design enhances the fit and effectively prevents sharp edges from damaging the grouting hose, thus extending the service life of the grouting hose.
[0014] 3. Facilitates separation operation: The outer sleeve surface is threaded with a threaded nut block. By rotating the threaded nut block, the drive disc can be pulled to separate the expansion plate from the grouting hose, making it easier to fasten the grouting hose to the connecting pipeline, thus improving the flexibility and convenience of operation.
[0015] 4. Provides lubrication and sealing: The surfaces of the expansion plate and the inner wall of the grouting hose that are in contact with each other are coated with wear-resistant grease, which facilitates the separation of the expansion plate and the grouting hose and provides a sealing effect after separation, effectively preventing grout leakage.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0023] Please see Figure 1-3 This utility model provides a technical solution: a pipeline connection component for grouting in building construction, including a grouting hose 1 and a connecting pipeline 3. When grouting is performed in building construction, the grouting hose 1 is inserted into the position where grouting is required, and the end of the grouting hose 1 is placed outside the position where grouting is required, so as to facilitate connection with the grouting pump equipment.
[0024] When connecting the grouting hose 1 to the grouting pump device, an outer sleeve 2 is threaded onto the outer surface of the connecting pipe 3. Multiple expansion plates 4 are installed on the outer sleeve 2 via an expansion mechanism. The grouting hose 1 to be connected is inserted into the outside of the multiple expansion plates 4. Then, the expansion mechanism expands the multiple expansion plates 4 outwards until they abut against the outer surface of the grouting hose 1. As the expansion continues, the grouting hose 1 deforms outwards, and the opening becomes larger. The expansion mechanism is connected to the connecting pipe 3 via a telescopic rod 5. While the expansion mechanism expands the multiple expansion plates 4 outwards, it also moves the connecting pipe 3 towards the expansion plates 4 via the telescopic rod 5. Thus, when the expansion... While the expansion plate 4 expands the opening of the grouting hose 1, it also drives the connecting pipe 3 to move closer to the expansion plate 4, that is, closer to the grouting hose 1 with its larger opening. This makes it easier to insert the port of the grouting hose 1 to the outside of the connecting pipe 3. Then, the other end of the connecting pipe 3 can be connected to the pump port of the grouting pump device. When using a soft grouting hose 1, and when the opening of the grouting hose 1 is smaller than the connecting pipe 3, the expansion mechanism allows the expansion plate 4 to expand the opening of the grouting hose 1 outward, so as to connect the grouting hose 1 to the connecting pipe 3, which improves the convenience of installing the grouting hose 1.
[0025] In one embodiment of this utility model, the expansion mechanism includes a drive disc 8 movably mounted on the outer sleeve 2, and the drive disc 8 has multiple sets of curved grooves 7 arranged in a circumferential array. The end of the expansion plate 4 is slidably fitted into the curved grooves 7 and the limiting grooves 9. The limiting grooves 9 are fixed on the outer sleeve 2. When the port of the grouting hose 1 is inserted to the outside of the multiple expansion plates 4, the drive disc 8 is rotated. The curved grooves 7 on the drive disc 8 are constructed to expand outward in the direction of the center. Thus, when the drive disc 8 rotates, the expansion plate 4 will expand outward along the curved grooves 7 through the curved grooves 7 and the limiting grooves 9. The expansion plate 4 will then contact the grouting hose 1, causing the port of the grouting hose 1 to expand and increase. Furthermore, due to the rotation of the drive disc 8, the connecting pipe 3 will be rotated synchronously through the telescopic rod 5. At this time, the connecting pipe 3 will move towards the port of the grouting hose 1 through the threaded structure between the connecting pipe 3 and the outer sleeve 2.
[0026] All of the expansion plates 4 are set in an arc shape, and when the expansion plates 4 expand outward and come into contact with the inner wall of the grouting hose 1, the arc-shaped outer surface of the expansion plate 4 fits against the inner wall of the grouting hose 1. The arc design increases the fit effect and prevents the sharp corners from damaging the grouting hose 1 and affecting its service life.
[0027] After the expansion plate 4 has expanded the opening of the grouting hose 1, it is necessary to separate the expansion plate 4 from the grouting hose 1 so that the opening of the grouting hose 1 covers the outside of the connecting pipe 3. The outer sleeve 2 is also threaded with a nut block 6. A connecting groove 10 is opened on some surfaces of the drive disc 8 near the nut block 6. A traction column 11 with one end movably connected to the surface of the nut block 6 is slidably fitted in the connecting groove 10. When the nut block 6 is rotated and moved to the maximum stroke by the traction drive disc 8, the expansion plate 4 separates from the grouting hose 1. At this time, the nut block 6 is rotated and moved on the surface of the outer sleeve 2, so that the traction column 11 pulls the drive disc 8 until the expansion plate 4 separates from the grouting hose 1. At this time, the grouting hose 1 covers the outer surface of the connecting pipe 3. Then, the grouting hose 1 is fastened to the connecting pipe 3 by wire or other fastening tools.
[0028] In order to facilitate the separation of the expansion plate 4 and the grouting hose 1, wear-resistant grease is coated on the surfaces of the expansion plate 4 and the inner wall of the grouting hose 1 that are in contact with each other, thereby providing lubrication to facilitate the separation of the expansion plate 4 and the grouting hose 1. After separation, the wear-resistant grease adhering to the inner wall surface of the grouting hose 1 can also provide a sealing effect to prevent grout leakage.
[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
