Technical Field

[0001] The utility model relates to the field of building construction, in particular to an embedded water-stopping temporary fixing device. Background Art

[0002] With the continuous development of the country's social economy, people have higher and higher requirements for building quality, and the waterproof requirements for walls, especially exterior walls, are also getting higher and higher. Various reserved holes in the construction process are often the main cause of water leakage. These reserved holes include the force connection points of the external scaffolding, the attachment points of tower cranes, elevators and other equipment, etc. These places are usually connected to the main exterior wall with through-wall (column) bolts. The bolt holes penetrate the main structure, and if they are not tightly blocked, they will become a hidden danger of water leakage.

[0003] The prior art adopts the method of setting a waterstop on the outside of the wall, such as patents CN105297925A, CN107989637A, CN101886435A, etc. However, as the waterstop or waterstop strip ages, there is still a risk of water leakage, and the setting of the waterstop increases the construction steps and prolongs the construction period. In terms of economic benefits, it does not conform to the purpose of the construction proposal of energy conservation and emission reduction. Utility Model Content

[0004] In view of the above problems, the utility model provides an embedded water-stopping temporary fixing device, which can prevent the formation of a water seepage channel running through the main structure while ensuring the effective connection between the temporary structure and the main body, thereby effectively solving the problem of water seepage through the temporary reserved holes of the main body.

[0005] An embedded water-stopping temporary fixing device comprises an embedded pad, the embedded pad is provided with a through hole for connecting fastening bolts, the inner side of the embedded pad is provided with a limit block for clamping the fastening bolts, the limit block is externally covered with a water-stopping cap, and the outer side of the embedded pad is provided with a sleeve for connecting a hole-making device.

[0006] Preferably, the limiting block is clamped with a fastening bolt.

[0007] Preferably, the vertical width of the through hole is greater than the lateral width, and the limit blocks are symmetrical structures arranged on both sides of the vertical axis of the through hole.

[0008] Preferably, the limit block comprises an upper limit plate and a lower limit plate, and a groove is arranged between the two limit plates.

[0009] Preferably, the inner side surface of the sleeve is provided with a connecting thread.

[0010] Preferably, a clamping block is provided on the inner side surface of the sleeve.

[0011] Preferably, the axis of the sleeve and the embedded pad are arranged perpendicular to each other.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. This device has a pre-embedded pad in the wall. The wall inside the pad is not transparent. The fastening bolts are connected through the pre-embedded pad, and the external connected components are connected through the fastening bolts. After the construction is completed, the fastening bolts are removed, and then the blind holes in the wall are sealed with sealing materials. Compared with the traditional through-wall bolt connection, no through-hole channel is formed, and no through-seepage channel is formed, which avoids water seepage in the exterior wall during use and affects the use function of the building.

[0014] 2. The embedded pad is an embedded structure, and there will be no phenomena such as patching holes and rusting inside the building that affect the visual quality.

[0015] 3. When this device is reserved, no plastic pipes and other materials are used, and there is no need to chisel again, which reduces the generation of garbage and is beneficial to environmental protection.

[0016] 4. The system has a simple structure and workers can operate it skillfully after simple training. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0031] like Figure 1-11 As shown, the utility model discloses an embedded temporary water-stopping fixing device, comprising an embedded pad 1, a water-stopping cap 6, a hole-forming device 8, and a fastening bolt 5, which is made of a steel plate, and its outer dimensions and thickness are determined by the strength of the concrete structure. A rectangular through hole 2 is arranged at the center of the embedded pad, and the vertical width of the through hole is greater than the horizontal width. The limit blocks 3 are symmetrically arranged on the inner side of the embedded pad and on both sides of the vertical axis of the through hole. The limit blocks include an upper limit plate and a lower limit plate, and a groove is arranged between the two limit plates. The water-stopping cap 6 is connected to the inner side of the embedded pad outside the limit block, and the sleeve 4 is connected to the outer side of the embedded pad. The inner side of the sleeve is provided with a connecting thread, and the front end of the hole-forming device 8 is processed with an external thread to cooperate with the internal thread. After the wall is poured and the hole-forming device 8 is removed, the fastening bolt 5 is passed through the through hole 2 and then rotated 90 degrees to engage with the limit block 3. The inner side of the sleeve is provided with a clamping block.

[0032] The embedded pad can be made into a porous combination form according to the requirements of the temporary structure to be connected to the outside of the building.

[0033] The water stop cap is welded to the embedded pad to form a whole. The weld should be tight to block the water seepage channel.

[0034] The hole former is a cylinder with a variable outer diameter. The outer thread at one end is adapted to the inner thread of the connecting sleeve. A rubber sealing ring is set at the threaded end of the hole former to prevent cement slurry from entering the thread and making the hole former unable to be pulled out. The socket can be inserted with steel bars or steel pipes to increase the torque and facilitate the removal of the hole former after the template is removed.

[0035] The diameter and length of the fastening bolt are determined according to the force calculation and the required exposed length outside. A welded stopper is formed at one end to form a T-shaped head, which can be stuck in the limit block of the embedded pad to limit the rotation of the bolt rod.

[0036] The operation process of the device is as follows:

[0037] 1. After the reinforcement of the concrete structure is tied, place the combination of the embedded pad 1 and the water stop cap 6 at the required position. It should be firmly fixed and accurately positioned during installation, and the water stop cap should have a protective layer.

[0038] 2. Put the rubber sealing ring on the hole former 8 and screw it into the connecting sleeve 4 of the embedded pad 1. When screwing it in, the rubber sealing ring should be squeezed to increase the sealing effect. The outside of the hole former should be brushed with an isolation agent.

[0039] 3. Set up the template 7. The template should leave a hole at the position of the hole former so that the hole former is exposed outside the template.

[0040] 4. After acceptance, pour concrete. When the required strength is reached, remove the formwork, insert the steel bar or short steel pipe into the socket at the tail of the hole puncher, and rotate the hole puncher to make it exit the reserved hole.

[0041] 5. Pass the fastening bolt 5 through the middle hole of the embedded pad, rotate it 90 degrees and insert it into the limit block.

[0042] 6. The exposed end of the fastening bolt can be connected to the structural member 10 to be temporarily fixed through the nut 11

[0043] 7. After the temporary fixed structure is removed after use, knock the fastening bolt into the hole to make the stopper come out of the limit block, and then rotate the fastening bolt and pull it out of the hole.

[0044] 8. Finally, the hole is sealed with a sealing material 9, which is a micro-expanding material.

[0045] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
