Description

Technical Field

[0001] The utility model relates to the technical field of building devices, in particular to a blocking template device for reserved holes and gaps in drainage pipes. Background Art

[0002] As an essential component of housing construction, water supply and drainage facilities provide comfort and convenience for people's lives. During the installation of water supply and drainage facilities, drainage pipes often pass through the floor slab. Therefore, when the concrete is poured into the floor slab, a hole with a diameter slightly larger than the pipe is reserved to facilitate the subsequent laying of the pipe. After the drainage pipe passes through the reserved hole in the floor slab, it needs to be fixed and the gap between the hole wall and the outer wall of the pipe needs to be sealed with cement.

[0003] Traditionally, drainage pipes are tied with wires passed through gaps and hung above the floor, or expansion bolts are drilled under the floor and the pipes are hung using connectors such as clips. However, these traditional methods have the following drawbacks:

[0004] Cement is poured directly to fill the gaps. During the construction process, part of the cement at the bottom of the floor slab often falls along the pipe wall, causing material waste, affecting the density of the cement, reducing the sealing effect, and causing water leakage in the later stage. If it is not cleaned in time, it will also affect the appearance quality of the drainage pipe and increase the deadweight of the drainage pipe. After the cement is cured, the iron wire running through the gap is difficult to clean. Due to its own corrosion in the later stage, it is bound to cause water leakage problems at this location, which greatly affects people's living experience. The practice of drilling expansion bolts often damages pipelines, steel bars, etc. embedded in the floor slab. Later repairs are time-consuming and labor-intensive. Workers are also required to work at height during the drilling process, which poses certain safety risks. Therefore, the utility model provides a sealing template device for reserved holes and gaps in drainage pipes, which facilitates construction and effectively solves the above-mentioned problems.

DETAILED DESCRIPTION

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. Usually, the components of the embodiments of this application described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0032] Embodiment 1

[0033] As Figures 1 to 7 , a plugging template device 10 for the gap of the reserved hole of a drainage pipe of the present utility model includes a tightening ring 1, and the tightening ring 1 is used to be sleeved on the outer periphery of the drainage pipe 20.

[0034] The tightening ring 1 includes two semi-ring bodies 11 buckled left and right, and the two semi-ring bodies 11 are detachably locked and combined with each other; a tightening hole 12 for the drainage pipe 20 to pass through is formed in the middle of the tightening ring 1, and the inner wall of the tightening hole 12 is in tight fit with the outer wall of the drainage pipe 20; a rough surface (not shown in the figure) may be provided on the inner wall of the tightening hole 12 to increase the friction force and strengthen the fixing effect between the tightening ring 1 and the drainage pipe 20.

[0035] A plugging plate 21 is respectively provided at the top of the two semi-ring bodies 11, and the two plugging plates 21 are combined into a plugging disc 2 as the two semi-ring bodies 11 are buckled; a plugging hole 22 for the drainage pipe 20 to pass through is formed in the middle of the plugging disc 2, and the diameter of the plugging hole 22 is equal to the outer diameter of the drainage pipe 20. At the same time, the outer diameter of the plugging disc 2 is larger than the inner diameter of the reserved hole 30; thus, the plugging disc 2 can be used to plug the hole gap 301 generated after the drainage pipe 20 is inserted into the reserved hole 30 of the drainage pipe on the floor slab 50, and it can prevent the cement 40 from leaking out when pouring the cement 40.

[0036] A plurality of suction cups 3 facing upward are provided on the top surface of the plugging disc 2, and at least one suction cup 3 is provided on each plugging plate 21; the suction cups 3 can be vacuum-adsorbed to the bottom surface of the floor slab 50. Thus, after the drainage pipe 20 is fixed by the tightening ring 1, the drainage pipe 20, the plugging template device 10, and the floor slab 50 can be fixed by the suction force of the suction cups 3, without tying iron wires or drilling expansion bolts.

[0037] The top surface of the sealing disk 2 is also provided with a sealing ring 4 on the outer periphery of the sealing hole 22. The outer diameter of the sealing ring 4 is not less than the inner diameter of the reserved hole 30. The sealing ring 4 includes two semi-annular elastic members 41, which are respectively fixed to the two sealing plates 21 and combined into the sealing ring 4 as the two semi-annular bodies 11 interlock. The sealing ring 4 is provided to fill the gap between the bottom surface of the floor slab 50 and the top surface of the sealing disk 2 after the suction cup 3 is provided, ensuring that the sealing disk 2 can achieve a tight sealing of the hole gap 301. That is, the sealing ring 4 can achieve coordinated deformation with the suction cup 3 to ensure that it is always in close contact with the bottom surface of the floor slab 50 and blocks the hole gap 30. In this embodiment, the sealing ring 4 can be made of rubber or other elastic materials.

[0038] Thus, the blocking template device 10 of this embodiment holds the drain pipe 20 tightly by the tightening ring 1, and then fixes the drain pipe 20 to the bottom surface of the floor 50 by the suction cup 3, and at the same time uses the blocking plate 2 to block the hole gap 301, which can ensure the density and blocking effect of the cement 40 in the hole gap of the reserved hole 30 of the drainage pipe when the cement 40 is poured subsequently; and the blocking template device 10 is a two-half split structure. When in use, it is only necessary to select the predetermined position of the drain pipe 20 and directly lock it to achieve the installation operation. It is convenient and efficient to use, which can improve construction efficiency, and can be disassembled and reused after use.

[0039] In this embodiment, the blocking disk 2 can be annular, and the blocking plate 21 can be semi-annular. Thus, the left and right halves of the blocking template device 10 can have completely the same structure, which is convenient for production and free combination.

[0040] In this embodiment, four suction cups 3 are evenly spaced circumferentially on the top surface of the blocking plate 2, so each blocking plate 21 has two suction cups 3. The suction cups 3 have a strong vacuum adsorption capacity, ensuring that the drain pipe 20 is firmly adsorbed on the floor 50.

[0041] In this embodiment, an annular support platform 5 may be provided between the sealing ring 4 and the sealing disk 2. The annular support platform 5 includes two semi-annular support portions 51. The two support portions 51 are respectively fixed to the upper sides of the two sealing plates 21. The two elastic members 41 are respectively fixed to the upper sides of the two support portions 51 and indirectly fixed to the two sealing plates 21. The provision of the annular support platform 5 can reduce the thickness of the sealing ring 4 to save costs and ensure a good sealing effect of the sealing ring 4.

[0042] In this embodiment, the outer diameter of the blocking disk 2 is larger than that of the clamping ring 1; a reinforcing angle seat 6 is provided between the upper portion of the semi-ring body 11 and the bottom surface of the blocking plate 21 to increase the supporting force of the blocking disk 2 and make the device stronger and more secure.

[0043] In this embodiment, the two semi - ring bodies 11 are detachably locked and fixed through a locking mechanism 7.

[0044] Specifically, the locking mechanism 7 may include two locking components 71, which are respectively arranged at the two abutting ends 13 of the two semi - ring bodies 11; each locking component 71 includes two locking seats 711 and a bolt 712. The two locking seats 711 are respectively arranged on the outer walls of the semi - ring bodies 11 on the left and right sides of the abutting end 13. Corresponding lock holes 713 are provided on the two locking seats 711, and the bolt 712 passes through the two lock holes 713 in sequence to lock and fix the corresponding abutting end 13.

[0045] Thus, through the locking operation of the two bolts 712 on the four locking seats 711, the locking connection of the two semi - ring bodies 11 can be realized. Moreover, the bolt 712 can be a quick - release screw, so as to achieve manual locking and removal, and tool - free operation can be avoided.

[0046] Refer to Figure 7 , the construction method of the present utility model can be as follows:

[0047] 1. First, calculate the length of the drain pipe 20 protruding above the floor slab 50 on the upper layer. Combining with the thickness of the floor slab 50, draw the positioning line of the plugging template device 10 on the drain pipe 20.

[0048] 2. After unscrewing the bolts 712 of the plugging template device 10, sleeve it on the drain pipe 20 according to the positioning line, and then screw the bolts 712 back on to fix the plugging template device 10 on the drain pipe 20.

[0049] 3. Gently push and squeeze the plugging disc 2 with both hands. After the air in the suction cup 3 above the plugging disc 2 is exhausted, let go. During this process, the suction cup 3 and the elastic plugging ring 4 deform synergistically, always keeping close to the bottom of the floor slab 50 and blocking the gap 30 of the reserved hole 30.

[0050] 4. Workers pour cement 40 into the drain pipe 20 and the hole gap 30 on the upper layer of the floor slab 50. After curing for 24 hours, unscrew the bolts 712, use cardboard to lift the edge of the suction cup 3 to fill the suction cup 3 with air, and then remove the plugging template device 10 for repeated use.

[0051] The present utility model may also have at least the following advantages:

[0052] 1. It can effectively prevent the cement 40 from falling, ensure the compactness and plugging effect of the cement 40 in the hole gap 30, and ensure the integrity of the appearance of the drain pipe 20. In addition, the plugging template device 10 has a simple structure, is easy to process and manufacture, is convenient to use, can be removed and reused after the final setting of the cement 40, and effectively improves the construction efficiency of water supply and drainage facilities.

[0053] 2. Skillfully use the vacuum sucker 3 to adsorb on the bottom of the floor slab 50, and use the adsorption force of the sucker 3 to bear the weight of the drain pipe 20, abandoning the traditional method of fixing with iron wire perforation or the practice of drilling expansion bolts 712. The construction is convenient and efficient. After the plugging template device 10 is buckled at the corresponding height position of the drain pipe 20, it can be pressed against the bottom of the floor slab 50.

[0054] Embodiment 2

[0055] As Figure 8 shown, the structure of this embodiment is basically the same as that of the above-mentioned Embodiment 1. The main difference is that the locking mechanism 7 in this embodiment is an annular clamp 72, and the annular clamp 72 is arranged around the outer wall of the tightening ring 1. The annular clamp 72 can adopt the existing structure, and can also realize the locking and fixing between the two semi-ring bodies 11 to ensure that the tightening ring 1 holds the drain pipe 20 tightly.
