Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and specifically relates to a waterproof structure and construction method for multi-row combined pre-embedded steel pipe through-wall panels. Background Technology

[0002] In existing engineering construction techniques, the construction of multi-row combined embedded steel pipes penetrating wall panels presents several challenges. Due to the small spacing and large number of embedded steel pipes, inadequate concrete vibration at the bottom of the pipes during concrete pouring can occur. Furthermore, the poor fluidity and self-compacting properties of commercial concrete typically affect the density of the wall panel's concrete structure, thus compromising the waterproofing function of the structural layer. During waterproofing on the water-facing side of the concrete wall panel, the lack of continuous sealing between the multi-row embedded steel pipes prevents the application of waterproof coatings and membranes, posing a risk of water leakage. Post-construction treatment of water leakage in the concrete wall panel is extremely costly and ineffective, potentially requiring multiple treatments. Summary of the Invention

[0003] The present invention provides a waterproof structure and construction method for multi-row combined pre-embedded steel pipe through-wall panels, which effectively solves the problem of water leakage risk in concrete walls during the construction of multi-row combined pre-embedded steel pipe through-wall panels.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] This invention discloses a multi-row combined pre-embedded steel pipe through-wall waterproof structure, comprising pre-embedded steel pipes, a water-facing water-stop support plate, and a water-retaining support plate on the back side. The water-facing and back side water-stop support plates are arranged opposite to each other. The water-facing water-stop support plate has a plurality of first mounting holes evenly spaced apart, and the back side water-stop support plate has a plurality of second mounting holes evenly spaced apart. The first and second mounting holes correspond one-to-one. One end of the pre-embedded steel pipe passes through the first mounting hole and is installed on the water-facing water-stop support plate. On the plate, the other end of the pre-embedded steel pipe passes through the corresponding second mounting hole and is installed on the back water-stop support plate. The distance between two adjacent pre-embedded steel pipes is equal and not less than twice the diameter of the pre-embedded steel pipe and not less than 100mm. The front water-stop support plate is provided with a front water-stop ring. The front water-stop ring is set away from the back water-stop support plate and is arranged around the perimeter of the front water-stop support plate. The first mounting hole is located inside the front water-stop ring.

[0006] Furthermore, support reinforcing rings are provided at the installation positions of the backwater-stopping support plate and the pre-embedded steel pipe, and at the installation positions of the frontwater-stopping support plate and the pre-embedded steel pipe, with the support reinforcing rings located at the bottom of the pre-embedded steel pipe.

[0007] Furthermore, the supporting reinforcing ring includes a U-shaped support ring and a mounting ring. The support ring is disposed at the bottom of the corresponding pre-embedded steel pipe, and the mounting ring is inserted into the corresponding first mounting hole and second mounting hole.

[0008] Furthermore, the wall thickness of the pre-embedded steel pipe is 3mm-4mm.

[0009] Furthermore, the diameter of the pre-embedded steel pipe is 20mm-500mm.

[0010] Furthermore, the thickness of the water-facing water-stop support plate and the water-retaining support plate on the back side is 3mm-5mm.

[0011] The waterproofing construction method based on the above-mentioned multi-row combined pre-embedded steel pipe through-wall waterproofing structure is characterized by the following steps:

[0012] S1. Select the required diameter and quantity of embedded steel pipes according to the thickness of the concrete wall panel and the purpose of the embedded steel pipes. Determine the installation position of the selected embedded steel pipes in the design drawings. Select the water-facing water-stop support plate and the back water-stop support plate according to the diameter, quantity, purpose and installation position of the selected embedded steel pipes. Mark the installation position of the embedded steel pipes on the selected water-facing water-stop support plate and the back water-stop support plate. Drill the first installation hole and the second installation hole at the marked installation positions on the water-facing water-stop support plate and the back water-stop support plate respectively. Weld the water-facing water-stop ring to the water-facing water-stop support plate. The first installation hole is located inside the water-facing water-stop ring.

[0013] S2. Each of the pre-embedded steel pipes passes through the corresponding first mounting hole of the water-facing side water-stop support plate and the corresponding second mounting hole of the water-retaining side water-stop support plate. The distance between the water-facing side water-stop support plate and the water-retaining side water-stop support plate is determined according to the thickness of the concrete wall panel. Support reinforcing rings are welded at the installation positions of the water-retaining side water-stop support plate and the pre-embedded steel pipe, respectively. The pre-embedded steel pipes are welded at the corresponding installation positions of the water-facing side water-stop support plate and the water-retaining side water-stop support plate. The waterproof structure assembly is completed.

[0014] S3. Rust removal and anti-corrosion treatment of the pre-embedded steel pipe, the water-facing water-stop support plate, the water-return water-stop support plate, the water-facing water-stop ring, and the welding positions;

[0015] S4. Place the waterproof structure, after anti-corrosion treatment, into the designated position on the concrete wall.

[0016] S5. Pour concrete and vibrate it to compact it.

[0017] The beneficial effects of this invention are:

[0018] This application discloses a multi-row combined pre-embedded steel pipe through-wall waterproofing structure, comprising a water-facing side water-stop support plate, a water-retaining side water-stop support plate, pre-embedded steel pipes, and a water-facing side water-stop ring. The structure is simple and low-cost, and is used for waterproofing pre-embedded steel pipes penetrating walls. The water-facing and water-retaining side water-stop support plates are arranged opposite each other. The water-facing side water-stop support plate has multiple first mounting holes drilled at even intervals, and the water-retaining side water-stop support plate has multiple second mounting holes drilled at even intervals, each corresponding to one of the first mounting holes. The left end of the pre-embedded steel pipe passes through the first mounting hole and is welded and fixed to the water-facing side water-stop support plate, while the right end passes through the second mounting hole and is welded and fixed to the water-retaining side water-stop support plate. This forms a multi-row combined pre-embedded steel pipe through-wall waterproofing structure. This structure, together with the poured concrete, forms a closed concrete wall, effectively preventing deformation of the multi-row combined pre-embedded steel pipe through-wall waterproofing structure under upper loads and ensuring the vertical bearing capacity of the concrete wall. The spacing between adjacent embedded steel pipes is equal and not less than twice the diameter of the embedded steel pipe and not less than 100mm. This ensures sufficient spacing between adjacent embedded steel pipes, facilitating concrete flow and vibration, promoting uniform and thorough concrete compaction, and ensuring the compaction of the concrete at the bottom of the embedded steel pipes during concrete pouring. This, in turn, guarantees the density of the concrete structure of the concrete wall panel and improves its waterproofness. A water-facing water-stop ring is welded to the water-facing support plate, with the water-facing water-stop ring facing away from the back water-stop support plate. The first installation hole is located inside the water-facing water-stop ring. The water-facing water-stop ring, combined with the waterproofing material outside the concrete wall panel, forms a completely sealed waterproof structure. This improves the waterproofing construction quality of multi-row combined embedded steel pipes penetrating the wall panel, effectively reduces the risk of leakage, avoids maintenance costs due to leakage caused by multi-row combined embedded steel pipes penetrating the wall panel, and reduces maintenance costs. This application presents a multi-row combined pre-embedded steel pipe through-wall waterproofing structure, which improves the load-bearing capacity and waterproofing reliability of concrete walls and can be used in waterproofing projects such as basements and tunnels. This application also provides a waterproofing construction method based on this multi-row combined pre-embedded steel pipe through-wall waterproofing structure, which is simple to construct, low in cost, and has good waterproofing effect, significantly reducing the risk of water leakage from concrete walls.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1 , Figure 2As shown, the present invention discloses a multi-row combined pre-embedded steel pipe through-wall waterproof structure, comprising a pre-embedded steel pipe 3, a water-facing water-stop support plate 1, and a water-retaining support plate 2. The water-facing water-stop support plate 1 and the water-retaining support plate 2 are arranged opposite to each other. The water-facing water-stop support plate 1 has a plurality of first mounting holes evenly spaced, and the water-retaining support plate 2 has a plurality of second mounting holes evenly spaced. The first mounting holes and the second mounting holes correspond one-to-one. One end of the pre-embedded steel pipe 3 passes through the first mounting hole and is installed on the water-facing water-stop support plate 1. The other end of the pre-embedded steel pipe 3 is installed on the back water-stop support plate 2 through the corresponding second mounting hole. The distance between two adjacent pre-embedded steel pipes 3 is equal and not less than twice the diameter of the pre-embedded steel pipe 3 and not less than 100mm. The front water-stop support plate 1 is provided with a front water-stop ring 5. The front water-stop ring 5 is set away from the back water-stop support plate 2. The front water-stop ring 5 is arranged around the perimeter of the front water-stop support plate 1. The first mounting hole is located inside the front water-stop ring 5. Specifically, the spacing between two adjacent horizontal or vertical pre-embedded steel pipes 3 is equal and not less than twice the diameter of the pre-embedded steel pipe 3 and not less than 100mm. When the diameter of two adjacent horizontal or vertical pre-embedded steel pipes 3 is less than 50mm, the spacing between the two adjacent pre-embedded steel pipes 3 is 100mm. When the diameter of two adjacent horizontal or vertical pre-embedded steel pipes 3 is greater than or equal to 50mm, the spacing between the two adjacent pre-embedded steel pipes 3 is not less than twice the diameter of the pre-embedded steel pipe 3.

[0027] A multi-row combined pre-embedded steel pipe through-wall waterproofing structure based on the above structure is composed of a water-facing water-stop support plate 1, a back water-stop support plate 2, a pre-embedded steel pipe 3, and a water-facing water-stop ring 5. It has a simple structure and low cost and is used for waterproofing pre-embedded steel pipe through-wall panels. Water-facing water-stop support plate 1 and water-retaining water-stop support plate 2 are arranged parallel to each other at intervals. Multiple first installation holes are drilled evenly at intervals on the water-facing water-stop support plate 1, and multiple second installation holes corresponding one-to-one with the first installation holes are drilled evenly at intervals on the water-retaining water-stop support plate 2. The left end of the pre-embedded steel pipe 3 passes through the first installation hole and is welded and fixed to the water-facing water-stop support plate 1, and the right end of the pre-embedded steel pipe 3 passes through the second installation hole and is welded and fixed to the water-retaining water-stop support plate 2, forming a multi-row combined pre-embedded steel pipe through-wall waterproof structure. The multi-row combined pre-embedded steel pipe through-wall waterproof structure and the poured concrete form a closed concrete wall panel, effectively preventing the multi-row combined pre-embedded steel pipe through-wall waterproof structure from deforming under the upper load and ensuring the vertical bearing capacity of the concrete wall panel. The spacing between two adjacent pre-embedded steel pipes 3 is equal and not less than twice the diameter of the pre-embedded steel pipe and not less than 100mm. This ensures sufficient spacing between adjacent pre-embedded steel pipes 3, facilitating concrete flow and vibration, promoting uniform and thorough concrete vibration, and ensuring the compaction of the concrete at the bottom of the pre-embedded steel pipes 3 during concrete pouring. This, in turn, ensures the compactness of the concrete structure of the concrete wall panel and improves its waterproofness. A water-facing water-stop ring 5 is welded to the water-facing water-stop support plate 1. The water-facing water-stop ring 5 extends out of the water-facing water-stop support plate 1, facing away from the back water-facing water-stop support plate. The first installation hole is located inside the water-facing water-stop ring 5. The water-facing water-stop ring 5, combined with the waterproofing material outside the concrete wall panel, forms a completely sealed waterproof structure. This improves the waterproofing construction quality of the multi-row combined pre-embedded steel pipe through-wall panel, effectively reduces the risk of leakage, avoids maintenance costs due to leakage caused by the multi-row combined pre-embedded steel pipe through-wall panel, and reduces maintenance costs. The multi-row combined pre-embedded steel pipe through-wall waterproof structure of this application improves the load-bearing capacity and waterproof reliability of concrete wall panels, and can be used in waterproofing projects such as basements and tunnels.

[0028] As one possible implementation method, such as Figure 1 , Figure 2 As shown, support reinforcing rings 4 are provided at the installation positions of the back water-stop support plate 2 and the pre-embedded steel pipe 3, and at the installation positions of the front water-stop support plate 1 and the pre-embedded steel pipe 3. The support reinforcing rings 4 are located at the bottom of the pre-embedded steel pipe 3.

[0029] For example, the supporting reinforcing ring 4 is welded to the opposite sides of the water-facing water-stop supporting plate 1 and the back water-stop supporting plate 2. The supporting reinforcing ring 4 is also welded to the edge of the first mounting hole of the water-facing water-stop supporting plate 1 and the edge of the second mounting hole of the back water-stop supporting plate 2. The supporting reinforcing ring 4 is welded to the bottom of the pre-embedded steel pipe 3 to provide support for the pre-embedded steel pipe 3 and enhance the stability of the multi-row combined pre-embedded steel pipe through-wall waterproof structure.

[0030] As one possible implementation method, such as Figure 1 , Figure 2 As shown, the support reinforcing ring 4 includes a U-shaped support ring and a mounting ring. The support ring is disposed at the bottom of the corresponding pre-embedded steel pipe 3, and the mounting ring is inserted into the corresponding first mounting hole and second mounting hole.

[0031] The inner wall of the U-shaped support ring fits snugly around the bottom of the embedded steel pipe 3, providing better support for the embedded steel pipe 3. The U-shaped mounting ring is integrally formed at one end of the U-shaped support ring. The inner walls of the U-shaped mounting ring and the U-shaped support ring are coplanar. The thickness of the U-shaped mounting ring is less than the thickness of the U-shaped support ring. The U-shaped mounting ring is installed in the corresponding first and second mounting holes. The outer wall of the U-shaped mounting ring fits snugly against the corresponding first and second mounting holes. The U-shaped support ring is welded to the connection position of the first mounting hole of the water-facing side water-stop support plate 1, and to the connection position of the second mounting hole of the water-retaining side water-stop support plate 2, thereby increasing the load-bearing strength of the support reinforcing ring 4 and providing more reliable support for the embedded steel pipe 3.

[0032] As one possible implementation method, such as Figure 1 , Figure 2 As shown, the wall thickness of the pre-embedded steel pipe 3 is 3mm-4mm.

[0033] The wall thickness of the embedded steel pipe 3 can be selected as 3mm-4mm according to the thickness of the concrete wall panel and the bearing capacity. For example, if the wall thickness of the embedded steel pipe 3 is 3mm, 3.5mm or 4mm, the thicker the concrete wall panel and the greater the bearing capacity, the thicker the wall thickness of the embedded steel pipe 3 should be, and vice versa.

[0034] As one possible implementation method, such as Figure 1 , Figure 2 As shown, the diameter of the pre-embedded steel pipe 3 is 20mm-500mm.

[0035] The diameter of the pre-embedded steel pipe 3 can be selected from 20mm to 500mm depending on the application, such as for home or office use, for example, 20mm or 30mm or 40mm or 50mm or 100mm or 200mm or 300mm or 400mm or 500mm.

[0036] As one possible implementation method, such as Figure 1 , Figure 2 As shown, the thickness of the water-facing water-stop support plate 1 and the water-retaining water-stop support plate 2 is 3mm-5mm.

[0037] The thickness of the water-facing support plate 1 and the water-retaining support plate 2 can be selected from 3mm to 5mm based on the thickness and load-bearing capacity of the concrete wall panel. For example, the thickness of the water-facing support plate 1, the water-retaining support plate 2, and the water-retaining support plate 2 can be 3mm, 4mm, or 5mm. The thicker the concrete wall panel, the greater the load-bearing capacity, and therefore the thicker the water-facing support plate 1 and the water-retaining support plate 2, and vice versa. Furthermore, the material of the water-facing support plate 1 and the water-retaining support plate 2 can be selected based on the corrosion conditions of the environment where the concrete wall panel is located. If the environmental corrosion is severe, corrosion-resistant stainless steel can be selected as the material for the water-facing support plate 1 and the water-retaining support plate 2.

[0038] The construction method for waterproofing multi-row combined pre-embedded steel pipe through-wall panels based on the above-mentioned waterproofing structure includes the following steps:

[0039] S1. Select the required diameter and quantity of embedded steel pipes 3 according to the thickness of the concrete wall panel and the purpose of the embedded steel pipes 3. Determine the installation position of the selected embedded steel pipes 3 in the design drawings. Select the water-facing water-stop support plate 1 and the back water-stop support plate 2 according to the diameter, quantity, purpose and installation position of the selected embedded steel pipes 3. Mark the installation position of the embedded steel pipes 3 on the selected water-facing water-stop support plate 1 and the back water-stop support plate 2. Drill the first installation hole and the second installation hole at the marked installation positions on the water-facing water-stop support plate 1 and the back water-stop support plate 2 respectively. Weld the water-facing water-stop ring 5 to the water-facing water-stop support plate 1. The first installation hole is located inside the water-facing water-stop ring 5.

[0040] S2. Each of the pre-embedded steel pipes 3 passes through the corresponding first mounting hole of the water-facing water-stop support plate 1 and the corresponding second mounting hole of the water-retaining support plate 2 on the back side. The distance between the water-facing water-stop support plate 1 and the water-retaining support plate 2 is determined according to the thickness of the concrete wall panel. Support reinforcing rings 4 are welded at the installation positions of the water-retaining support plate 2 and the pre-embedded steel pipes 3, and at the installation positions of the water-facing water-stop support plate 1 and the pre-embedded steel pipes 3. The pre-embedded steel pipes 3 are welded at the corresponding installation positions of the water-facing water-stop support plate 1 and the water-retaining support plate 2. The waterproof structure assembly is completed.

[0041] S3. Rust removal and anti-corrosion treatment of the pre-embedded steel pipe 3, the water-facing water-stop support plate 1, the water-return water-stop support plate 2, the water-facing water-stop ring 5, and the welding positions.

[0042] S4. Place the waterproof structure, after anti-corrosion treatment, into the designated position on the concrete wall.

[0043] S5. Pour concrete and vibrate it to compact it.

[0044] The above-mentioned multi-row combined pre-embedded steel pipe through-wall waterproofing construction method is simple to operate, low in cost, and has good waterproofing effect. It can improve the waterproofing construction quality of multi-row combined pre-embedded steel pipe through-wall panels and significantly reduce the risk of water leakage in concrete walls.

[0045] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
