Description

Technical Field

[0001] This invention relates to the technical field of pre-embedded electrical conduit construction, and in particular to a construction structure and method for pre-embedded electrical conduits that avoids opening holes in the formwork. Background Technology

[0002] When pre-embedding conduits in a wall, the first step is to mark the positions on the completed formwork (for junction boxes and wall socket / switch locations). Then, holes are made in the formwork at the marked down points to allow the conduits to pass through. Because making holes can damage the formwork, currently, during the construction of pre-embedded conduits, workers design a construction structure that avoids making holes in the formwork.

[0003] For example, Chinese utility model patent CN208971095U discloses a pre-embedded PVC prefabricated 90-degree elbow, including a base with an elbow socket in the center and multiple wood bolt holes around the socket. The base is fixedly connected to the structural wooden template by wood bolts. After the template is disassembled, the base separates from the template, and the tips of the wood bolts protrude from the wall. Workers need to cut the wood bolts, which is cumbersome and inefficient. Summary of the Invention

[0004] This invention provides a construction structure and method for pre-embedded electrical conduits that avoids opening holes in templates, which has the technical effect of improving the construction efficiency of pre-embedded electrical conduits.

[0005] This invention provides a construction structure for pre-embedded electrical conduits that avoids openings in templates, employing the following technical solution:

[0006] An electrical pre-embedded conduit construction structure that avoids opening holes in the template includes a fixed base plate installed on the template. A connecting pipe is connected to the side of the fixed base plate away from the template. Multiple screws are provided on the fixed base plate, and the fixed base plate is fixed to the template by the screws. The characteristic is that each screw corresponds to a protective cylinder, one end of which is open. The open end of the protective cylinder is fixed to the fixed base plate. When the template is separated from the fixed base plate, the screw can enter the protective cylinder.

[0007] Furthermore, the protective cylinder includes a first protective cylinder and a second protective cylinder. The first protective cylinder is fixed to the fixed base, and the end of the first protective cylinder away from the fixed base is inserted into the second protective cylinder and threadedly connected to the second protective cylinder.

[0008] Furthermore, a mounting hole is provided at the center of the fixed chassis, the outer diameter of the connecting pipe is smaller than the diameter of the mounting hole, and adhesive is provided between the outer wall of the connecting pipe and the inner wall of the mounting hole.

[0009] Furthermore, a PVC pipe is provided at the end of the connecting pipe away from the fixed chassis, and a retaining ring is fixed on the inner wall of the connecting pipe. One end of the PVC pipe is inserted into the connecting pipe and contacts the retaining ring.

[0010] Furthermore, a tapered mounting tube is connected to the center of the fixed chassis, and a connecting tube is sleeved on the mounting tube. A convex ring made of rubber is fixed on the outer wall of the mounting tube, and a slot for the convex ring to be inserted is opened on the inner wall of the connecting tube.

[0011] Furthermore, an installation block is fixed on the outer wall of the bottom end of the installation tube, and an installation groove for the installation block to be inserted is provided on the side of the fixed base near the template.

[0012] This invention also discloses a method for constructing electrical conduits that avoids opening holes in templates, comprising the following steps:

[0013] S1. After the formwork is erected, the electrical points are located and laid out on the formwork.

[0014] S2. Select either a straight pipe or a bent pipe for connecting the points according to the layout location.

[0015] S3. After the connecting pipes are selected and arranged, screws are driven into the connecting holes and fixed to the template. Before fixing, the connection direction of the connecting pipes needs to be adjusted.

[0016] S4. Next, connect the PVC pipe and the connecting pipe. The PVC pipe and the connecting pipe are connected by socket adhesive. The end face of the PVC pipe contacts the retaining ring. After inserting it forcefully, hold it for 5-10 seconds before releasing it to achieve a certain bonding strength.

[0017] S5. Pour concrete. After the concrete has solidified, dismantle the formwork by forcefully tapping it to detach it from the concrete.

[0018] S6. If the fixed base plate does not detach from the formwork, tap the tip of the screw to make the screw fully enter the first and second protective cylinders; if the fixed base plate detaches from the formwork, grind the pit on the wall with cement mortar.

[0019] Compared with the prior art, the present invention has the following technical effects:

[0020] When disassembling the template, if the fixing base does not detach with the template, the screws will detach from the template and protrude outside the wall. Tapping the tip of the screw will cause it to fall into the first and second protective sleeves. If the template detaches with the fixing base, the protruding ring will detach from the slot; the pit can be smoothed out with cement mortar. The structure and method of this invention eliminate the need to cut the screws, facilitating worker construction and improving efficiency. The first and second protective sleeves facilitate the containment of the screws. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this invention are used to explain the invention, but are not intended to limit the invention. Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3 This application discloses an electrical conduit construction structure that avoids opening holes in the template, including a fixed base 2 installed on the template 1. The fixed base 2 has multiple connection holes 21, which are evenly arranged along the circumference of the fixed base 2. The fixed base 2 is provided with multiple screws 22, each screw 22 corresponding to one connection hole 21. The screws 22 pass through the connection holes 21 and are threadedly connected to the fixed base 2.

[0030] Multiple protective cylinders 23 are installed on the side of the fixed base 2 away from the template 1. The protective cylinder 23 is open at one end near the fixed base 2 and closed at the other end. Each connecting hole 21 corresponds to one protective cylinder 23, and the axis of the connecting hole 21 coincides with the axis of the corresponding protective cylinder 23. The protective cylinder 23 includes a first protective cylinder 231 and a second protective cylinder 232. The first protective cylinder 231 is fixedly connected to the fixed base 2. The end of the first protective cylinder 231 away from the fixed base 2 is inserted into the second protective cylinder 232 and threadedly connected to the second protective cylinder 232. Screws 22 are encased in the first protective cylinder 231 and the second protective cylinder 232.

[0031] A connecting pipe 6 is detachably connected to the center of the fixed base 2. The connecting pipe 6 is a straight pipe or a bent pipe. An installation hole 3 is opened at the center of the fixed base 2. One end of the connecting pipe 6 is inserted into the installation hole 3. Adhesive 31 is provided between the outer wall of the bend of the connecting pipe 6 and the hole wall of the installation hole 3. The PVC of the bend of the connecting pipe 6 is fixed to the hole wall of the installation hole 3 by the adhesive 31.

[0032] Since the fixed base plate 2 is cast onto the outer wall of the wall, when the formwork 1 is removed, the adhesive 31 may break, and the fixed base plate 2 may detach along with the formwork 1. In this case, a pit will be left on the wall, which can be smoothed out with cement mortar. When disassembling the formwork 1, if the fixed base plate 2 does not detach along with the formwork 1, the screw 22 will detach from the formwork 1 and protrude outside the wall. Tapping the tip of the screw 22 will cause it to fall into the first protective sleeve 231 and the second protective sleeve 232, eliminating the need for workers to cut off the screw 22 and improving work efficiency.

[0033] A PVC pipe 4 is connected to the end of the connecting pipe 6 away from the fixed base 2. A blocking ring 41 is fixed on the inner wall of the connecting pipe 6. The end face of the PVC pipe 4 contacts the blocking ring 41 to prevent the PVC pipe 4 from being inserted too deeply or too shallowly. The PVC pipe 4 and the connecting pipe 6 are fixed together with glue.

[0034] This application also discloses a method for constructing electrical conduits that avoids openings in formwork, comprising the following steps:

[0035] S1. After the template 1 is erected, the electrical points are located and laid out on the template 1.

[0036] S2. Based on the layout points, select either the straight pipe connecting pipe 6 or the bent pipe connecting pipe 6;

[0037] S3. After the selection and arrangement of the connecting pipe 6 are completed, screw 22 is driven into the connecting hole 21 and fixed with the template 1. Before fixing, the connection direction of the connecting pipe 6 needs to be adjusted.

[0038] S4. Next, connect PVC pipe 4 and connecting pipe 6. PVC pipe 4 and connecting pipe 6 are connected by socket adhesive. Apply special glue to the end of PVC pipe 4 within 20mm. Rotate and insert it into connecting pipe 6 with force to a depth of 15mm. The end face of PVC pipe 4 should contact the retaining ring 41 to prevent the PVC pipe 4 from being inserted too deeply or too short. After forcefully inserting, hold for 5-10 seconds before releasing to achieve a certain bonding strength.

[0039] S5. Pour concrete. After the concrete has solidified, dismantle formwork 1 by forcefully tapping formwork 1 to detach it from the concrete.

[0040] S6. If the fixed base plate 2 does not fall off with the template 1, tap the tip of the screw 22 to make the screw 22 fully enter the first protective cylinder 231 and the second protective cylinder 232; if the fixed base plate 2 falls off with the template 1, grind the pit on the wall with cement mortar. Example 2

[0041] Reference Figure 4 and Figure 5 The difference from Embodiment 1 is that an installation tube 5 is provided in the installation hole 3. The installation tube 5 is a tapered tube. One end of the installation tube 5 extends out of the connection hole 21 and multiple protruding rings 51 are fixed on the outer wall of the installation tube 5. The protruding rings 51 are made of rubber. A slot 61 is provided on the inner wall of the end of the connection tube 6 near the fixed base 2 to engage with the protruding rings 51.

[0042] Two mounting blocks 7 are fixed on the outer wall of the mounting tube 5 away from the connecting tube 6. The two mounting blocks 7 are symmetrically arranged about the axis of the mounting tube 5. The fixed base 2 has a mounting groove 71 at one end away from the connecting tube 6. The mounting groove 71 is located on both sides of the connecting hole 21. The mounting blocks 7 are inserted into the mounting groove 71.

[0043] When connecting the mounting tube 5 and the connecting tube 6, first insert the mounting tube 5 into the connecting hole 21 and put the mounting block 7 into the mounting groove 71. Then fix the fixing base plate 2 and the template 1 with screws 22. Then insert the mounting tube 5 into the connecting tube 6 so that the convex ring 51 engages with the slot 61.

[0044] When disassembling template 1, if the fixing base 2 does not detach with template 1, screw 22 will detach from template 1 and protrude outside the wall. Tapping the tip of screw 22 will cause it to fall into the first protective sleeve 231 and the second protective sleeve 232. If template 1 detaches with the fixing base 2, the protruding ring 51 will detach from the slot 61. The pit will be smoothed out with cement mortar.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention are included within the scope of protection of the present invention.
