Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of support for pipes exiting buildings, and in particular to a waterproof and anti-sinking support structure for pipes exiting buildings from basement exterior walls that does not require penetration of the exterior wall. Background Technology
[0002] During building construction, the pipes exiting the basement exterior walls are laid on backfill soil, mostly located below the outdoor ground level. They often bend and break due to the settlement of the backfill soil above and below the pipes, which requires the construction unit to rework and repair them, increasing construction costs.
[0003] Currently, the traditional practice is to use expansion bolts to fix the brackets on the exterior wall to support the pipes. This installation method will damage the concrete structure and the waterproofing of the exterior wall, thus causing leakage problems. Utility Model Content

[0016] like Figures 1-2 As shown, this utility model discloses a waterproof and anti-sinking support structure for a basement exterior wall pipe that does not penetrate the exterior wall. It includes a structure 1 and a pipe 2 that penetrates the structure 1 and is horizontally arranged. In this embodiment, the structure 1 is the basement exterior wall, and the pipe 2 extends to the outside through the exterior wall. A groove 3 is provided on the outer surface of the structure 1 below the pipe 2. The groove 3 is reserved when the structure 1 is poured with concrete. A support frame 4 is provided at the groove 3 to support the pipe 2.
[0017] The support frame 4 is made of high-strength plastic material and has a right-angled triangular structure 1, which includes an upper right-angled side 4.1, a side right-angled side 4.2, and a lower inclined side 4.3. The side right-angled side 4.2 is embedded in the groove 3. The size and depth of the groove 3 are adapted to the size and thickness of the side right-angled side 4.2 to ensure that the groove 3 can tightly hold the main support frame 4 in the future. The upper right-angled side 4.1 is supported on the bottom surface of the pipe 2, and the lower inclined side 4.3 is located below the pipe 2 and connects the upper right-angled side 4.1 and the side right-angled side 4.2. The mathematical stability of the triangle is used to achieve stable support for the pipe 2. At the same time, a non-expansion bolt fixing method is used to protect the concrete structure 1 and the waterproofing of the external wall.
[0018] Pipe 2 is fixed to the upper right-angle side 4.1 by galvanized iron wire 5. Multiple galvanized iron wires 5 are set at intervals along the length of pipe 2, so that pipe 2 and support frame 4 are connected as a whole. Pipe 2 restricts the position of support frame 4, and support frame 4 supports pipe 2. This bidirectional action ensures the stability of support frame 4 and pipe 2.
[0019] Alternating grooves 6 and inserts 7 are provided on both sides of the upper right-angled side 4.1 along its length. Galvanized iron wire 5 is wound around the insert 7 and fixed. The insert 7 is generally elliptical in shape 1. There is a winding gap 8 between the insert 7 and the upper right-angled side 4.1. The galvanized iron wire 5 passes around the pipe 2 and is fixed on the insert 7 by winding around the winding gap 8. At the same time, the winding gap 8 also has a fixing effect on the galvanized iron wire 5, so that the galvanized iron wire 5 will not affect the pipe 2 when it is tightened.
[0020] Furthermore, a patch block 9 is provided between the groove 3 and the lower inclined edge 4.3. The patch block 9 is integrally formed with the lower inclined edge 4.3, so that the groove 3 is completely filled, ensuring the embedding effect of the right angle edge 4.2 on the opposite side of the groove 3.
[0021] The specific operating steps are as follows: In the preliminary preparation, based on the pipe diameter and material of the outlet pipe 2 and the wall structure 1, select a high-strength plastic support frame 4 of appropriate specifications. The size of the support frame 4 is flexibly determined according to the length of the pipe 2, generally 30*60cm. Also prepare galvanized iron wire 5. Before the concrete exterior wall pouring construction, according to the design requirements, accurately mark the position of the reserved groove 3 on the template and install the mold for forming the groove 3. The groove is 30*4cm. The size of the mold is adapted to the size of the right angle side 4.2 of the support frame 4 to ensure that the groove 3 can tightly lock the support frame 4 later.
[0022] During the concrete pouring process, the concrete construction specifications must be strictly followed to ensure that the mold position for the reserved groove 3 does not change and that the shape and size of the groove 3 meet the design requirements. After the concrete reaches a certain strength, the mold should be carefully removed and the debris inside the groove 3 should be cleaned.
[0023] For the support frame 4 installation, the right-angled side 4.2 of the triangular support frame 4 is slowly inserted into the pre-reserved wall groove 3. The size of the groove 3 is just enough to ensure that the support frame 4 is in a horizontal state, thus ensuring the stability of the installation.
[0024] Pipe 2 is fixed to support frame 4. One end of a galvanized iron wire 5 is wrapped around the initial position of the insert 7 and inserted into the winding gap 8 for fixation. Then, after the galvanized iron wire 5 is wrapped around pipe 2, the other end is wrapped and fixed to the insert 7 on the other side in the same way. The subsequent installation and fixation of galvanized iron wire 5 are carried out in sequence to bind and fix pipe 2 to the upper right angle side 4.1.
[0025] After installation, conduct a thorough inspection of the installation position and fixation of the support frame 4, as well as the overall condition of the pipe 2. If it is not stable or the position is off, make timely adjustments.
[0026] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
