Building wall hole sealing device and sealing method

Abstract

The application provides a building wall hole sealing device and sealing method. The outer baffle of the sealing device seals the outside of the hole. The bottom plate is fixed on the wall below the hole. Two T-shaped fixing members are fixed on the walls on both sides of the hole, and four clamping openings are formed between the two T-shaped fixing members and the walls. During construction, the outer baffle, the bottom plate and the two T-shaped fixing members are first fixed on the corresponding positions of the walls. Then, the two clamping strips of the dustpan opening are inserted into the first clamping opening and the fourth clamping opening. Then, the concrete is poured into the dustpan opening, and the concrete flows into the hole. Then, the vertical plate of the L-shaped baffle is inserted into the second clamping opening and the third clamping opening. The dustpan opening is removed, and the excess device is removed after the initial setting of the concrete in the hole. The dustpan opening can be removed before the initial setting of the concrete, so that the concrete in the dustpan opening can be easily cleaned, and the excess concrete bump does not need to be chiseled. The dustpan opening can be quickly used for the next hole sealing construction.

Description

Technical Field

[0001] This invention relates to the field of secondary construction technology, and in particular to a sealing device and method for sealing through-wall openings in buildings. Background Technology

[0002] In construction engineering, external scaffolding is mainly used for construction operations and safety protection. It is an indispensable part of building construction, and most high-rise structures use cantilevered external scaffolding. Buildings using cantilevered scaffolding inevitably use a large number of I-beams to support the base of the scaffolding through walls. According to national standards, one I-beam should be installed every 1.5 meters along straight sections of the exterior wall, with additional I-beams required at corners. National standards also stipulate that the height of a single cantilever should not exceed 20 meters, so a cantilever is generally required every four floors. Buildings using cantilevered scaffolding will have many pre-reserved I-beam openings (hereinafter referred to as: channel steel openings), which are rectangular in shape. Although the construction unit will re-pour these channel steel openings after the scaffolding is dismantled, these openings actually pose significant quality risks and leakage hazards.

[0003] Currently, the construction unit mainly uses the following two methods to seal these channel steel openings:

[0004] Existing technology 1: Flat formwork is erected on both the inside and outside of the opening. An inlet is left at the top of the inner formwork, and concrete is poured in through the inlet. However, concrete is fluid, and pouring it in through the inlet cannot completely fill the opening, leaving some gaps. After the concrete hardens, the formwork is removed for secondary filling, which involves pouring concrete back into the opening to basically fill the gaps left by the first filling. Its advantages are: simple formwork erection. Its disadvantages are: the first filling is time-consuming and labor-intensive; the concrete cannot be vibrated to ensure compaction; the concrete strength cannot be guaranteed; the concrete will flow out when filling to the opening; the secondary filling after formwork removal is merely perfunctory construction, failing to completely fill the gaps; the overall quality has significant potential risks, and there is a high risk of leakage.

[0005] Existing technology two: Flat formwork is used on the outside of the opening, and a hopper-shaped formwork is used on the inside. Concrete is poured in through the hopper, rising above the top surface of the opening. After the concrete hardens, both the flat and hopper formworks are removed. Removing the hopper formwork leaves a hopper-shaped concrete protrusion, which needs to be chiseled away to ensure a smooth inner wall surface. Its advantages are: the concrete is poured through the hopper, and the surface height exceeds the top of the opening; due to the fluidity of concrete, the compaction after vibration is guaranteed, filling all gaps in the opening and resulting in high overall pouring quality. Its disadvantages are: after demolding, the inner concrete of the opening forms a hopper-shaped protrusion, which needs to be chiseled away until flush with the wall surface. This process is time-consuming, labor-intensive, and costly, and may damage the already poured inner concrete of the opening.

[0006] Application No. 201810631424.6, Publication No. CN 108678370 A, applicant Yunnan Construction Investment Holding Group Co., Ltd. discloses a sealing device and method for pre-reserved openings in walls. The sealing device includes a main body installed at the pre-reserved opening in the wall, and fixing components for fixing the main body. The fixing components are installed on the wall and include vertical fixing components extending along both sides of the main body and horizontal fixing components extending along the bottom of the main body. The main body is located between the two vertical fixing components, forming an adjustable pouring opening. During construction, the required amount of concrete to be poured is first calculated. Concrete is poured through the pouring opening, and the size of the pouring opening is adjusted until the concrete is poured. At this point, the pouring opening is adjusted to its minimum position, i.e., the pouring opening is closed, and the sealing device for the pre-reserved opening in the wall is fixed. After the concrete has cured, the sealing device can be removed, and plastering is applied to finish the sealing of the pre-reserved opening in the wall. The advantages of this technology are that it does not produce excess concrete and eliminates the need for removing excess concrete. However, the sealing device is overly complex to operate, requiring precise calculation of the concrete pouring volume. Furthermore, the concrete inside the device cannot be effectively vibrated, making quality difficult to guarantee. Additionally, adjusting the pouring port position until it is closed is impractical in real-world operation. Finally, the sealing device requires complete concrete hardening before removal, resulting in a long waiting time of 2-3 days before it can be used for the next opening sealing operation. This leads to low reusability and slow construction speed, making it unsuitable for practical construction. Summary of the Invention

[0007] The purpose of this invention is to provide a sealing device for wall openings in buildings, in order to solve the problems in the prior art that require chiseling out "basket"-shaped concrete protrusions and that the concrete inside the opening cannot be effectively vibrated.

[0008] Another object of the present invention is to provide a method for sealing the opening of the wall through-hole in the building using the aforementioned sealing device.

[0009] A sealing device for wall penetrations in buildings includes two "T"-shaped fasteners, a base plate, an "L"-shaped baffle, a scoop opening, and an outer baffle.

[0010] The outer baffle is fixed to the outside of the wall, and the outer baffle seals the outside of the opening;

[0011] The base plate is fixed to the inside of the wall, and the base plate is horizontally fixed to the wall below the opening, with the upper surface of the base plate flush with the lower surface of the opening;

[0012] Two T-shaped fasteners are fixed to the inside of the wall and located on the left and right sides of the opening, respectively; the two T-shaped fasteners are the first T-shaped fastener and the second T-shaped fastener; the first T-shaped fastener forms a first latch and a second latch with the wall; the second T-shaped fastener forms a third latch and a fourth latch with the wall; the bottom surfaces of the two T-shaped fasteners are attached to the upper surface of the base plate;

[0013] The winnowing basket opening includes two side plates and one inclined plate; the two side plates are respectively set on both sides of the inclined plate, and the two side plates and the inclined plate form a winnowing basket opening shape; one side of each side plate is fixedly connected to the inclined plate, and the other side of each side plate is fixedly connected to a retaining strip; the two retaining strips of the winnowing basket opening are respectively embedded in the first retaining slot and the fourth retaining slot; the bottom surface of the winnowing basket opening is attached to the upper surface of the bottom plate.

[0014] The “L”-shaped baffle consists of a vertical plate and a horizontal plate, with the horizontal plate fixed to the top of the vertical plate. The left and right ends of the vertical plate are embedded in the second and third latches, and the bottom surface of the vertical plate is flush with the top surface of the base plate.

[0015] The two side plates, one inclined plate, and two retaining strips of the aforementioned winnowing basket opening are an integral structure.

[0016] The vertical and horizontal plates of the aforementioned "L"-shaped baffle are an integral structure.

[0017] The thickness of the aforementioned base plate is 0.3cm to 2cm.

[0018] The method for sealing a through-wall opening using the aforementioned sealing device for building openings includes the following steps:

[0019] Step 1:

[0020] First, roughen the concrete around the opening, then clean up any debris around the opening.

[0021] Step Two:

[0022] On the outside of the wall, seal the opening with an outer baffle and fix the outer baffle to the wall;

[0023] Step 3:

[0024] On the inside of the wall, fix the base plate horizontally to the wall below the opening, and ensure that the upper surface of the base plate is flush with the lower surface of the opening;

[0025] Step Four:

[0026] On the inside of the wall, fix two "T" shaped fasteners to the walls on the left and right sides of the opening respectively; the first "T" shaped fastener forms a first and a second latch with the wall; the second "T" shaped fastener forms a third and a fourth latch with the wall; and ensure that the bottom surface of the two "T" shaped fasteners is in contact with the upper surface of the base plate;

[0027] Step 5:

[0028] Align the two clips at the opening of the winnowing basket with the first and fourth clips, press the winnowing basket opening downwards, insert the two clips at the opening of the winnowing basket from top to bottom into the first and fourth clips, and make the bottom surface of the winnowing basket opening fit against the upper surface of the base plate;

[0029] Step Six:

[0030] Pour concrete into the hopper opening, and the concrete flows into the opening; when the top surface of the concrete exceeds the top surface of the opening by 1cm, stop pouring concrete; then vibrate the concrete in the hopper opening, at which point the opening will be completely filled with concrete.

[0031] Step Seven:

[0032] Align the two sides of the vertical plate of the "L"-shaped baffle with the second and third latches, press the horizontal plate down, so that the vertical plate is inserted into the second and third latches from top to bottom, and the bottom surface of the vertical plate is in contact with the upper surface of the base plate; the vertical plate seals the concrete in the opening;

[0033] Step 8:

[0034] Next, pull the hopper opening upwards to disengage the two clips from the first and fourth clips; after removing the hopper opening, clean away any excess concrete flowing out of it.

[0035] Step Nine:

[0036] After the concrete inside the opening has initially set, remove the two "T" shaped fasteners, the base plate, the "L" shaped baffle and the outer baffle. The concrete inside the opening will be flush with the inner and outer surfaces of the wall. Finally, the concrete inside the opening will be cured.

[0037] The beneficial effects of this invention are as follows:

[0038] 1. Setting up a sieve opening allows for convenient use of construction tools to vibrate the concrete when pouring the concrete at the opening. After vibration, the concrete inside the opening is compact and has a good solidification effect.

[0039] 2. The "L"-shaped baffle is inserted between the first "T"-shaped fastener and the second "T"-shaped fastener, which can separate the concrete inside and outside the opening. The "L"-shaped baffle seals the concrete inside the opening, making it easy to remove the hopper opening.

[0040] 3. Remove the hopper opening before the concrete sets, so that the excess flowing concrete can be easily cleaned away; after the concrete in the opening has initially set, remove the "L"-shaped baffle, so that the set concrete in the opening is flush with the wall surface; this avoids the problem of needing to chisel away excess set concrete protrusions outside the opening in the existing technology.

[0041] 4. Since there are a large number of channel steel openings, the present invention can immediately remove the hopper opening after the "L"-shaped baffle seals the opening with concrete. In this way, the hopper opening can be quickly put into the next opening sealing construction, which greatly improves the reuse rate of the hopper opening and speeds up the overall opening sealing construction.

[0042] 5. The hopper-shaped opening has a simple structure, and other components can be sourced locally on-site, reducing construction costs;

[0043] 6. This method can be used for construction of structural defects, openings, or openings at the top of structural columns where it is inconvenient to pour concrete. Attached Figure Description

Figure 7 and Figure 8 As shown, the left and right ends of the vertical plate 16 are embedded in the second slot 10 and the third slot 11, and the bottom surface of the vertical plate 16 is attached to the upper surface of the base plate 8.

[0067] The method for sealing a through-wall opening using the sealing device for building openings of the present invention includes the following steps:

[0068] Step 1:

[0069] First, roughen the concrete around opening 7, and then clean up the debris around opening 7.

[0070] Step Two:

[0071] On the outside of the wall 6, the opening 7 is sealed with an outer baffle 5 and the outer baffle 5 is fixed to the wall 6;

[0072] Step 3:

[0073] like Figure 1 and Figure 2As shown, on the inside of the wall 6, the base plate 8 is horizontally fixed to the wall below the opening 7, and the upper surface of the base plate 8 is flush with the lower surface of the opening 7.

[0074] Step Four:

[0075] like Figure 3 and Figure 4 As shown, on the inner side of the wall 6, two "T"-shaped fasteners are fixed to the walls on the left and right sides of the opening 7 respectively; a first "T"-shaped fastener 1 and a second "T"-shaped fastener 1 form a first latch 9 and a second latch 10 between themselves and the wall 6; a third latch 11 and a fourth latch 12 are formed between themselves and the wall 6; and the bottom surfaces of the two "T"-shaped fasteners are made to fit against the upper surface of the base plate 8.

[0076] Step 5:

[0077] like Figure 5 and Figure 6 As shown, align the two locking strips 15 of the hopper opening 4 with the first locking slot 9 and the fourth locking slot 12, press the hopper opening 4 downwards, and insert the two locking strips 15 of the hopper opening 4 from top to bottom into the first locking slot 9 and the fourth locking slot 12, so that the bottom surface of the hopper opening 4 is in contact with the upper surface of the base plate 8.

[0078] Step Six:

[0079] Pour concrete into the hopper opening 4, and the concrete flows into the opening 7; when the top surface of the concrete exceeds the top surface of the opening 7 by 1cm, stop pouring concrete; then vibrate the concrete in the hopper opening 4, at which point the opening 7 will be completely filled with concrete.

[0084] Step Nine:

[0085] After another 2-3 days, once the concrete inside opening 7 has initially set, remove the two "T" shaped fasteners, base plate 8, "L" shaped baffle 3, and outer baffle 5. The concrete inside opening 7 will then be flush with the inner and outer surfaces of wall 6. Figure 11 As shown; finally, the concrete inside opening 7 is cured.

[0086] In addition, the thickness of the base plate 8 is designed to be relatively thin, ranging from 0.3cm to 2cm. This is because when the opening 7 is close to the ground, the thinner base plate 8 can be horizontally set between the bottom surface of the opening 7 and the ground.
