Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a node structure for a group of pipes passing through an outer wall of a basement. Background Art

[0002] During the construction of a basement, it is often necessary to reserve through-wall pipes on the outer wall, including single or multiple through-wall pipes. In the traditional construction process where a group of pipes directly penetrates the outer wall of the basement, a large number of through-wall pipes need to be pre-buried in smaller outer wall openings. The space between the pipes is narrow, and when the outer wall openings are filled with concrete, it is easy to cause the concrete in the narrow space between the pipes to be vibrated loosely, resulting in structural defects such as honeycombs and holes in the outer wall of the basement, and there are quality risks such as leakage, which are difficult to repair later. Therefore, it is necessary to provide a node structure for a group of pipes to penetrate the outer wall of the basement, which can solve the problem of structural defects and quality risks of the outer wall caused by loose vibration of concrete at the node of the group of pipes in the prior art. Summary of the invention

[0003] The utility model aims to provide a node structure for a group of pipes to pass through the outer wall of a basement, which can solve the problem in the prior art that the concrete at the node where the group of pipes pass through the wall is not vibrated densely, resulting in structural defects and quality risks of the outer wall.

[0006] The sealing plate is formed with a plurality of pipe penetration holes, through which the pipe groups penetrate the sealing plate, and the pipe groups are fully welded and fixed to the sealing plate, so that the weld seals the gap between the pipe groups and the pipe penetration holes.

[0008] The embedded fixings include embedded corners and anchor bars; the embedded corners are circumferentially arranged along the edge of the outer wall opening, one end of the anchor bar is fixedly connected to the embedded corners, and the other end of the anchor bar is hook-shaped and anchored to the outer wall of the basement.

[0009] The embedded corner has an L-shaped structure, the horizontal section of the embedded corner is flush with the top / bottom surface of the exterior wall opening, and the vertical section of the embedded corner is flush with the inner / outer wall of the basement exterior wall; the sealing plate is overlapped with the vertical section of the embedded corner and fully welded and fixed, and the anchor bar is connected to the horizontal and vertical sections of the embedded corner at 45°.

[0017] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Please see attached Figure 1 and attached Figure 2A node structure for a group of pipes passing through the outer wall of a basement, comprising an embedded fixing 1, a sealing plate 2 and an asphalt glue 3; the embedded fixing 1 is embedded in the outer wall 4 of the basement, and a plurality of embedded fixings 1 are circumferentially arranged along the inner and outer edges of the outer wall opening, a pair of sealing plates 2 are respectively attached to the inner wall and the outer wall of the basement outer wall 4, and the pair of sealing plates 2 are respectively fixedly connected to the plurality of embedded fixings 1, so that the pair of sealing plates 2 cover and close the two ends of the outer wall opening; an asphalt pouring port 201 is formed at the lower part of the sealing plate 2, i.e., the bottom of the outer wall opening, so that the asphalt glue 3 is densely filled in the outer wall opening through the asphalt pouring port 201, and an observation port 202 is formed at the upper part of the sealing plate 2, i.e., the top of the outer wall opening.

[0019] In addition to having a good water-blocking effect and being able to meet the waterproofing requirements of the basement outer wall 4, the asphalt glue 3 also has good fluidity and can ensure the density of pouring in the narrow space between the pipe groups 5, thereby avoiding the formation of honeycombs and holes at the outer wall openings of the basement outer wall 4, thereby avoiding quality risks such as leakage of the basement outer wall 4.

[0020] At the same time, the sealing plate 2 is fixed to the basement outer wall 4 through the embedded fixing parts 1, and is firmly installed, which can effectively seal both ends of the outer wall opening, and together with the asphalt glue 3 form a sealing structure for the outer wall opening, ensuring the waterproof performance and integrity of the basement outer wall 4.

[0021] The asphalt pouring port 201 is set at the lower part of the sealing plate 2, that is, the bottom of the external wall opening, which can effectively ensure the pouring density of the asphalt glue 3 in the cavity sandwiched by a pair of sealing plates 2, that is, the external wall opening; the observation port 202 is set at the upper part of the sealing plate 2, that is, the top of the reserved opening, to facilitate observation of the pouring condition of the asphalt glue 3.

[0022] According to the requirements of pouring the asphalt glue 3, an asphalt pouring port 201 and an observation port 202 may be provided on one of the sealing plates 2, or both of the sealing plates 2 may be provided with an asphalt pouring port 201 and an observation port 202. Alternatively, an asphalt pouring port 201 may be provided on one of the sealing plates 2, and an observation port 202 may be provided on the other sealing plate 2.

[0023] Please see attached Figure 2 The sealing plate 2 is formed with a plurality of pipe penetration holes (not shown in the figure), and the group of pipes 5 penetrate the sealing plate 2 through the plurality of pipe penetration holes. The group of pipes 5 and the sealing plate 2 are fully welded and fixed, so that the weld 6 closes the gap between the group of pipes 5 and the pipe penetration holes.

[0024] Preferably, the sealing plate 2 is a steel plate, and the pipes of the group pipe 5 are steel pipes. The sealing plate 2 and the pipes are fixed by welding at the penetration nodes, and the weld 6 closes the gap between the group pipe 5 and the pipe penetration hole, thereby ensuring the firmness of the wall penetration of the group pipe 5 and the waterproof performance of the wall penetration node of the group pipe.

[0025] Please see attached Figure 1 The asphalt pouring port 201 and the observation port 202 are respectively located on two sides of the sealing plate 2.

[0026] The observation port 202 is far away from the asphalt pouring port 201, and is not easily blocked by the asphalt glue 3 in the initial stage of pouring. Therefore, the pouring condition of the asphalt glue 3 can be effectively observed through the observation port 202 during the entire pouring process of the asphalt glue 3. When the asphalt glue 3 overflows from the observation port 202, the asphalt glue in the outer wall opening is densely filled, which is beneficial to ensure the pouring quality of the asphalt glue 3.

[0027] Please see attached Figure 1 The embedded fixing part 1 includes an embedded corner portion 101 and an anchoring bar 102; the embedded corner portion 101 is circumferentially arranged along the edge of the outer wall opening, one end of the anchoring bar 102 is fixedly connected to the embedded corner portion 101, and the other end of the anchoring bar 102 is hook-shaped and anchored to the outer wall 4 of the basement.

[0028] Preferably, the embedded corner 101 can be made of angle steel, and the anchor bar 102 can be made of steel bar. One end of the angle steel is welded to the steel bar into an integrated structure, and the other end of the steel bar is bent into a hook shape to improve the anchoring strength in the basement outer wall 4.

[0029] Please see attached Figure 1 The embedded corner 101 is in an L-shaped structure, the horizontal section of the embedded corner 101 is flush with the top / bottom surface of the exterior wall opening, and the vertical section of the embedded corner 101 is flush with the inner / outer wall of the basement exterior wall 4; the sealing plate 2 is overlapped with the vertical section of the embedded corner 101 and fully welded and fixed, and the anchor bar 102 is connected to the horizontal and vertical sections of the embedded corner 101 at 45°.

[0030] Preferably, the angle steel specification and length of the embedded corner 101 can be selected according to actual use requirements. Usually, the external wall opening is a rectangular structure, and four angle steels can be embedded circumferentially along the edge of the external wall opening of the rectangular structure to facilitate the overlap of the sealing plate 2. The sealing plate 2 and the vertical section of the angle steel need to reserve a certain overlap length and be fixed by full welding, which can ensure that the weld 6 can effectively close the gap between the sealing plate 2 and the vertical section of the angle steel, thereby ensuring the sealing of the external wall opening.

[0031] The anchor bar 102 is connected to the horizontal section and the vertical section of the embedded corner 101 at 45 degrees, so that the overall force is uniform and stable, and the anchoring strength is further improved.

[0032] Please see attached Figure 1 To Attachment Figure 3 , the construction process of the utility model is:

[0033] During the construction of the basement exterior wall 4, an exterior wall opening of corresponding size is set as required, and the embedded corner 101 with anchor bars 102 is tied and fixed inside the basement exterior wall 4 along the edge of the exterior wall opening and the inner and outer walls of the basement exterior wall 4, and the basement exterior wall 4 is poured and maintained.

[0034] In the processing plant, according to the design requirements, a steel plate is used as a sealing plate 2, and the steel plate is trimmed and drilled to form an observation port 202 located on one side of the upper portion of the steel plate, an asphalt pouring port 201 located on the other side of the lower portion of the steel plate, and a plurality of pipe holes located in the middle of the steel plate.

[0035] During on-site construction, the group of pipes 5 are passed through the preset pipe holes of the sealing plate 2, and a pair of sealing plates 2 are respectively welded to the vertical sections of the embedded corners 101 and the group of pipes 5, so that the pair of sealing plates 2 are respectively sealed at both ends of the external wall opening.

[0036] Asphalt glue 3 is injected into the inner cavity between a pair of sealing plates 2, i.e., the outer wall opening, from the lower asphalt pouring port 201 by high pressure grouting. The pouring of asphalt glue 3 can be observed through the observation port 202. When asphalt glue 3 overflows from the observation port 202, the asphalt glue 3 in the outer wall opening is dense. The pipe group 5 and the sealing plate 2 are welded so that the weld 6 seals the gap of the pipe penetration hole, and the construction of the pipe group 5 passing through the basement outer wall 4 is completed.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
