Description

Technical Field

[0001] This invention belongs to the field of conduit technology, and relates to a fixing device and method for pre-installing conduits in walls. Background Technology

[0002] In the pre-installation of electrical wiring in buildings, two common methods are used to fix the pre-installed conduits in the wall: one is to use a short pipe to bind and fix multiple parallel PVC conduits embedded in the wall, and then remove the fixing short pipe after the floor slab concrete is poured; the other is to bind the pre-installed conduits in the wall with tape, and then remove the tape after the floor slab is poured. While these two methods can fix the pre-installed conduits in the wall to a certain extent, the distance between the conduits cannot be controlled, and they are prone to displacement due to impact during floor slab pouring. The inability to control the spacing may affect the location of connected sockets, switches, and boxes, increasing the difficulty of later installation. Furthermore, construction must be carried out layer by layer, and even for standard floors in high-rise buildings, the same procedures need to be repeated, reducing construction efficiency and wasting materials. For conduits pre-installed in secondary structures, the connection construction must wait until the masonry stage, making the pre-installed conduits prone to damage or blockage, increasing the difficulty of later construction. Therefore, a new fixing device and method for pre-installed conduits in walls are needed to solve the above problems. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a fixing device and method for pre-installed conduits in walls, which can solve technical problems such as uncontrollable conduit spacing, easy damage to pre-installed conduits, increased difficulty in later construction, and waste of resources.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Reference Figure 1 As shown, a fixing device for pre-installed conduits in a wall can connect conduits 1 and reinforcing bars 2 that need to be fixed. The device is characterized by including a pipe 3, a first fixing plate 4, a first connecting rod 5, and a buckle 6. The conduit 1 is inserted into the pipe 3. The pipe 3 is slidably connected to the first fixing plate 4 and connected to the first connecting rod 5 through the first fixing plate 4. The end of the first connecting rod 5 away from the first fixing plate 4 is connected to the reinforcing bar 2 and connected to the conduit 1 through the buckle 6. The conduit 1 is secured by pipe 3, and then the device is firmly fixed to the reinforcing steel 2 in the concrete slab by the first connecting rod 5. The conduit 1 and the first connecting rod 5 are then secured again by clips 6. This device not only protects the conduit 1 but also ensures its precise positioning and prevents it from shifting during construction. The end of the first connecting rod 5 away from the first fixing plate 4 is detachable. After the slab is poured, the connection between the first connecting rod 5 and the reinforcing steel 2 can be removed, and the device can then be dismantled. This is very convenient, allows for multiple uses, improves construction efficiency, ensures construction quality, and saves costs. Alternatively, the same number of pipes 3 as the conduit 1 can be installed simultaneously to fix multiple conduits 1, greatly increasing construction speed and saving materials. Users can flexibly adjust the setup according to actual needs.

[0026] Preferably, there are at least two pipes 3, and a telescopic rod 7 is provided between the outer walls of the two pipes 3. Adjusting the telescopic rod 7 can change the axial distance between adjacent pipes 3. In this embodiment, the two ends of the telescopic rod 7 are connected to adjacent pipes and its length is adjustable, thereby changing the lateral distance between adjacent pipes 3, and thus making the distance between adjacent conduits 1 adjustable. This achieves precise positioning between conduits, improving work efficiency and construction quality.

[0027] Preferably, the outer wall of the pipe 3 is provided with a first groove 31, and the first fixing plate 4 is provided with a first protrusion 41 that matches the first groove 31. The first protrusion 41 can slide along the first groove. In this embodiment, the pipe 3 can move along the body of the first fixing plate 4, thereby making the position of the conduit 1 adjustable and achieving the purpose of rapid positioning.

[0028] It should be noted that the present invention does not specifically limit the shape and size of the first groove, the second groove 32 and the third groove, as long as they can achieve the same function. Users can flexibly adjust them according to actual applications, making it highly practical.

[0029] Preferably, the side wall of the pipe 3 is provided with a second groove 32, and the two ends of the telescopic rod 7 are provided with connecting clips. The connecting clips are connected to the pipe 3 through the second groove 32, and adjusting the telescopic rod 7 allows the pipe 3 to move along the direction of the first fixed plate 4. In this embodiment, as shown... Figure 2 As shown, the pipe 3 is symmetrically provided with two second grooves 32 around its circumference. The larger end of the groove is located at the bottom of the groove, and the smaller end is located at the outer wall of the pipe. The shape of the locking block 82 matches the second groove 32, so that it can be inserted into the second groove 32. If the telescopic rod 7 becomes longer, the connecting card will push the pipes 3 on both sides away, thereby increasing the distance between the conduits in the pipe 3. If the telescopic rod 7 becomes shorter, the connecting card will pull the pipes 3 on both sides closer, thereby decreasing the distance between the conduits in the pipe 3, thus achieving precise fixation between the conduits 1.

[0030] Preferably, the connecting card 8 includes a connecting segment 81 and card blocks 82 symmetrically arranged on both sides of the connecting segment. The shape of the card blocks matches the second groove 32, so that they can be inserted into the second groove 32.

[0031] Preferably, the buckle 6 includes a fastener, a buckle body, and connecting parts symmetrically arranged on both sides of the buckle body. The buckle body is fixedly connected to the first connecting rod 5 and forms a cavity with the connecting parts. The end of the connecting part away from the buckle body is connected by a fastener, and the conduit is disposed in the cavity. Multiple buckles 6 can be set between the first connecting rod 5 and the conduit 1, and between the second connecting rod 11 and the conduit 1. Users can flexibly adjust them according to the actual use scenario, which is very convenient. After the pouring is completed, the buckles 6 can be removed and reused.

[0032] Preferably, an annular sealing strip is provided between pipe 3 and conduit 1. The annular sealing strip fills the gap between pipe 3 and conduit 1, making the reserved conduit less likely to be damaged or blocked during the concrete pouring process, improving the speed and quality of subsequent construction, and making the fixation between pipe 3 and conduit 1 more stable.

[0033] Preferably, a second fixing plate 10 is provided on the side of the pipe 3 away from the first fixing plate 4. The second fixing plate 10 has a second protrusion 101, and the pipe 3 has a third groove that matches the second protrusion 101. The second protrusion 101 can slide along the third groove. In this embodiment, the first fixing plate 4 and the second fixing plate 10 are steel plates of the same shape and size, and they are symmetrically distributed on both sides of the pipe 3. This makes the device more stable in fixing the conduit, ensuring that it will not be disturbed or displaced during construction, and improving the construction quality.

[0034] Preferably, the second fixing plate 10 is connected to the reinforcing bar 2 via the second connecting rod 11, and the second connecting rod 11 is connected to the conduit 1 via multiple clips 6.

[0035] The method for using the fixing device for pre-installed conduits in walls as described above is characterized by comprising the following steps:
