Abstract
Description
Technical Field
[0001] This utility model relates to the field of embedded conduit technology, specifically a device for embedding conduits at the bottom of structural beams without drilling holes. Background Technology
[0002] Pre-embedded conduits are installed before the concrete is poured in a building. They can be installed before the main structure of the building is completed, avoiding the tedious work of drilling and grooving later, thus improving construction efficiency.
[0003] Traditional water and electricity pre-embedded process uses a method of drilling holes in the template to position the conduits passing through the bottom of the beam. The conduits are directly inserted into the holes, and mechanical drilling directly damages the template, reducing its service life. The drilling process generates a lot of sawdust and wood chips on the template, especially at the bottom of the beam, which are difficult to clean. Moreover, the vibration generated by drilling can cause template misalignment, deformation, and loosening of connections.
[0004] In view of this, it is necessary to develop a device for pre-embedding conduits at the bottom of structural beams without drilling holes, so as to avoid damage to the formwork. Utility Model Content
[0005] The purpose of this utility model is to provide a device for pre-embedding conduits at the bottom of structural beams without drilling holes, so as to solve the technical problem mentioned in the background art that drilling holes to pre-embed conduits will directly lead to the destruction of the formwork and reduce the service life of the formwork.

[0007] Preferably, an outer docking post is symmetrically installed on one side of the first side positioning block.
[0008] Preferably, one side of the second side positioning block has symmetrically provided outer docking holes.
[0009] Preferably, one side of the inner positioning block is symmetrically provided with an inner docking hole, and the inner docking hole is inserted and connected to the outer docking post.
[0010] Preferably, an inner docking post is symmetrically installed on the other side of the inner positioning block, and the inner docking post is inserted and connected to the outer docking hole.
[0011] Preferably, the first side positioning block, the inner side positioning block, and the second side positioning block are equipped with an elastic limiting component. The elastic limiting component includes a mounting groove, a spring body, and an arc-shaped pressure plate. The mounting groove is respectively opened on the top inner wall of the first side positioning block, the inner side positioning block, and the second side positioning block. The spring body is installed inside the mounting groove, and the bottom end of the spring body is equipped with an arc-shaped pressure plate.
[0012] Preferably, the inner side of the positioning component is positioned with a wire tube body.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. In this utility model, in order to avoid drilling holes in the bottom formwork of the beam, the conduit body is positioned on the surface of the bottom formwork of the beam by a positioning component.

[0024] Please see Figures 1-4 A device for pre-embedded conduit at the bottom of structural beams without the need for drilling;
[0025] Includes: a beam bottom formwork 1 and a positioning component 2. The positioning component 2 is fixed on the top of the beam bottom formwork 1. The positioning component 2 is used to position the pre-embedded conduit on the surface of the beam bottom formwork 1. The positioning component 2 includes a first side positioning block 4, an inner side positioning block 6 and a second side positioning block 9. The first side positioning block 4 and the second side positioning block 9 are respectively installed on the top of the beam bottom formwork 1 by fixing nails. The inner side positioning block 6 is connected between the first side positioning block 4 and the second side positioning block 9. An outer connecting column 5 is symmetrically installed on one side of the first side positioning block 4. An outer connecting hole 10 is symmetrically opened on one side of the second side positioning block 9. An inner connecting hole 7 is symmetrically opened on one side of the inner side positioning block 6, and the inner connecting hole 7 is inserted and connected to the outer connecting column 5. An inner connecting column 8 is symmetrically installed on the other side of the inner side positioning block 6, and the inner connecting column 8 is inserted and connected to the outer connecting hole 10.
[0026] The bottom beam formwork 1 provides an installation position for the pre-embedded conduit body 3. To avoid drilling holes in the bottom beam formwork 1, the conduit body 3 is positioned on the surface of the bottom beam formwork 1 by the positioning component 2. The positioning component 2 consists of a first side positioning block 4, an inner side positioning block 6, and a second side positioning block 9. The first side positioning block 4 and the second side positioning block 9 are located on both sides and fixed on the bottom beam formwork 1. The inner side positioning block 6 is inserted and connected to the outer side docking column 5 and the outer side docking hole 10 through the inner side docking hole 7 and the inner side docking column 8, respectively, so that the inner side positioning block 6 can be installed on the inner side. This allows multiple inner side positioning blocks 6 to be spliced on the inner side, making the use of the positioning component 2 more flexible and allowing the number of conduit bodies 3 to be positioned to be changed as needed.
[0027] Please see Figure 1 , Figure 3 and Figure 4 A device for pre-embedded conduit at the bottom of structural beams without the need for drilling;
[0028] The system includes an elastic limiting component. The first side positioning block 4, the inner side positioning block 6, and the second side positioning block 9 are equipped with the elastic limiting component. The elastic limiting component includes a mounting groove 11, a spring body 12, and an arc-shaped pressure plate 13. The mounting groove 11 is respectively opened on the top inner wall of the first side positioning block 4, the inner side positioning block 6, and the second side positioning block 9. The spring body 12 is installed inside the mounting groove 11. The arc-shaped pressure plate 13 is installed at the bottom end of the spring body 12. The inner side of the positioning component 2 is positioned by the conduit body 3.
[0029] The arc-shaped pressure plate 13 in the elastic limiting component is elastically installed inside by the spring body 12. When the positioning component 2 positions the conduit body 3, the arc-shaped pressure plate 13 can apply pressure to the conduit body 3 from the top under the action of the spring body 12. At the same time, under the action of the arc-shaped pressure plate 13, the positioning component 2 can also effectively position conduit bodies 3 of different sizes. Conduit bodies 3 with smaller diameters can be positioned from the top by the arc-shaped pressure plate 13, making the positioning component 2 more widely applicable.
[0030] The working principle is as follows: First, the positioning component 2 is used to assemble the required number of conduit bodies 3. During assembly, multiple inner positioning blocks 6 can be connected and used. The first side positioning blocks 4 and the second side positioning blocks 9 located on both sides are fixed by fixing nails to fix the positioning component 2. When fixed, the conduit body 3 is located inside the positioning component 2, so that the conduit body 3 is positioned on the surface of the beam bottom formwork 1, so that the conduit body 3 can be pre-embedded without drilling.
