Description

Technical Field

[0001] This utility model relates to the field of screw hole sealing technology, specifically a screw hole sealing device for construction. Background Technology

[0002] In the construction of high-rise and super high-rise buildings in cities, most of the concrete walls are built using aluminum formwork and all-steel attached lifting (commonly known as climbing formwork). However, the through-wall bolts used for aluminum formwork reinforcement and climbing formwork installation need to pass through the concrete wall. After the concrete wall is completed, the through-wall bolts need to be removed. Since the diameter of the through-wall hole caused by the through-wall bolts is relatively large, the bolt hole needs to be sealed later.

[0003] The current traditional sealing process involves filling both ends with waterproof mortar and injecting expanding foam in the middle. This process is complicated and not only results in an incomplete seal, but also leads to low wall strength, easy leakage, and poor thermal and sound insulation. Furthermore, the overall cost is high and the quality control of the project is difficult. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a screw hole sealing device for construction, which solves the problem that traditional sealing processes can lead to incomplete sealing of the wall and consequently low wall strength.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A screw hole sealing device for construction includes two sets of aluminum formwork and a concrete wall between the two sets of aluminum formwork. A climbing frame is installed on the aluminum formwork, and multiple sets of connecting holes are opened in the concrete wall. A sealing mechanism is installed between the two sets of aluminum formwork to prevent the connecting holes from being not sealed tightly.

[0007] The sealing mechanism includes a tapered sleeve clamped and connected by two sets of aluminum templates. The tapered sleeve has an insertion hole and a tapered protrusion ring installed on it.

[0008] Preferably, the sealing mechanism further includes a cement cone that is inserted and installed on the connection hole, and the cement cone is coated with cement slurry.

[0009] Preferably, the sealing mechanism further includes a horn groove formed in the concrete wall and communicating with the connecting hole, and a through-wall screw that is slidably connected to the tapered sleeve is installed between the two sets of aluminum templates.

[0010] Preferably, both ends of the through-wall screw are threaded with fastening bolts.

[0011] Preferably, a connecting frame is installed between the two sets of aluminum templates.

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

[0013] 1. This utility model, through the setting of the sealing mechanism, allows the tapered sleeve to be removed along with the through-wall bolt by gently tapping it from the small end to the large end with a small hammer. Then, the cement cone is coated with cement slurry and inserted into the connection hole. The polymer cement mortar fits tightly with the wall structure, improving the bonding between the sealing material and the wall structure, further enhancing the strength and thermal insulation of the wall, and avoiding the situation where the wall is not sealed tightly and thus has low wall strength, which is a problem with traditional sealing processes.

[0014] 2. This utility model improves the impermeability of the exterior wall by aligning the conical protrusion on the conical sleeve with the outside of the building during installation, and by providing an attachment point for the subsequent waterproof coating under the action of the horn groove, and by wrapping a water-swellable waterstop strip around the middle of the cement cone.

[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] The current traditional sealing process involves filling both ends with waterproof mortar and injecting expanding foam in the middle. This process is cumbersome and not only results in an incomplete seal but also leads to low wall strength, easy leakage, and poor thermal and sound insulation. (Refer to...) Figures 1-4 This embodiment proposes a screw hole sealing device for construction. The sealing mechanism 4 solves the problem of insufficient wall sealing and low wall strength caused by traditional sealing processes. The device includes two sets of aluminum formwork 1 and a concrete wall 3 between them. A climbing frame 2 is installed on the aluminum formwork 1. Fastening bolts 5 are threaded to both ends of the through-wall screw 47. A connecting frame 6 is installed between the two sets of aluminum formwork 1. Multiple connecting holes 31 are formed in the concrete wall 3. Before installing the aluminum formwork 1, the through-wall screw 47 is passed through a tapered... The two ends of the sleeve 41 and the through-wall screw 47 pass through the aluminum formwork 1 and the climbing frame 2 respectively, so that the tapered sleeve 41 is clamped between the two sets of aluminum formwork 1. The climbing frame 2 is connected to the aluminum formwork 1 by the fastening bolt 5 and the through-wall screw 47. When pouring concrete, the tapered sleeve 41 is removed from the concrete wall 3 to form the connecting hole 31. A sealing mechanism 4 is installed between the two sets of aluminum formwork 1 to prevent the connecting hole 31 from being not sealed tightly, which solves the problem that the traditional sealing process will cause the wall to be not sealed tightly, resulting in low wall strength.

[0023] The sealing mechanism 4 includes a tapered sleeve 41 clamped and connected by two sets of aluminum templates 1. The tapered sleeve 41 has an insertion hole 42 and a tapered protruding ring 43 installed on it. The sealing mechanism 4 also includes a cement cone 44 inserted into the connecting hole 31. The size of the cement cone 44 can be customized according to actual conditions, and the cement cone 44 is made of fine aggregate concrete. The strength of the cement cone 44 can be determined according to specific design requirements. It is formed with polymer mortar and coated with cement slurry 45. The sealing mechanism 4 also includes a flared groove 46 formed in the concrete wall 3 and communicating with the connecting hole 31. When the tapered sleeve 41 is removed, the tapered protruding ring 43 on the tapered sleeve 41 will form a flared groove 46 in the concrete wall 3. When the tapered sleeve 41 is installed, the direction of the tapered protruding ring 43 on the tapered sleeve 41 can be facing outwards from the building. The groove 46 provides an attachment point for subsequent waterproof coating, and a water-swellable waterstop strip can be wrapped around the middle of the cement cone 44, thereby effectively improving the impermeability of the exterior wall. A through-wall screw 47 that slides between the two sets of aluminum formwork 1 is installed and is connected to the tapered sleeve 41. After the concrete is formed, the climbing frame 2 and aluminum formwork 1 need to be removed. Then, the tapered sleeve 41 can be removed together with the through-wall screw 47 by gently tapping it from the small end to the large end with a small hammer. Then, the cement cone 44 is coated with cement slurry 45 and inserted into the connecting hole 31. The polymer cement mortar fits tightly with the wall structure, which improves the bonding between the sealing material and the wall structure, further improving the strength and thermal insulation of the wall. This avoids the situation where the wall is not sealed tightly and the wall strength is low due to the traditional sealing process.
