Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a formwork structure for a group of pipe-through-wall openings and a construction method thereof. Background Art

[0002] During the construction process, when mechanical and electrical, fire protection, HVAC and other professional pipelines pass through cast-in-place walls, it is often necessary to leave through-wall pipes; when the through-wall pipes of cast-in-place walls in a certain area are relatively concentrated, the usual practices for the formwork support are: 1. Cut the wooden formwork according to the diameter and position of the group of pipes for support. This method is complicated to construct, and it is difficult to accurately open the holes in the wooden formwork, resulting in leakage and loss of the formwork; 2. Use formwork with holes around the group of pipes, and use small pieces of formwork or foam boards and other materials to block the pipes. This method can easily cause uneven surfaces of components, requiring secondary chiseling, and even lead to insufficient structural dimensions.

[0003] Therefore, how to provide a formwork structure and a construction method for a group of pipe-through-wall openings that are simple in formwork, good in pouring effect, and not prone to leakage is a technical problem that needs to be urgently solved by those skilled in the art.

[0034] In order to describe the technical solution of the above invention in more detail, specific embodiments are listed below to demonstrate the technical effects; it should be emphasized that these embodiments are used to illustrate the present invention but not to limit the scope of the present invention.

[0035] The formwork structure of the group pipe wall opening provided by the present invention is as follows: Figures 1a to 4b As shown, including:

[0036] The hole-opening template 10, each pipe 50 passes through the reserved hole 11 of the hole-opening template 10;

[0037] The backing 20 is laid in the reserved hole 11, and on the side where the casting surface is located, the backing 20 and the hole-opening template 10 are located in the same plane, that is, the entire casting surface is flush; the edge of the backing 20 extends into the reserved hole 11 and is pasted on the outer facade of the hole-opening template 10;

[0038] The inner support bar 30 is supported between the backing 20 and the pipe 50 and between the pipes 50 in the reserved hole 11 to provide sufficient support for the backing 20;

[0039] And the back ribs 40 are installed on the outer facade of the hole-opening template 10, and are inserted between the pipes 50 around the reserved hole 11 to reinforce the entire formwork structure.

[0040] The present invention adopts a method of supporting formwork by blocking from the outside, and there is no need to cut the formwork according to the shape of the group of pipes. The construction operation is simple and quick, and the concrete pouring quality is good. It is not easy to cause problems such as hollowing and leakage, and reduces the subsequent rework and repair problems.

[0041] In some embodiments, please refer to Figure 1a , 1b The reserved hole 11 is a regular shape, such as a rectangle, a circle, etc. The hole size should not be too large to facilitate the subsequent template construction; and the reserved hole 11 is located in the middle of the opening template 10 to ensure that the subsequent backing 20 can be firmly pasted and evenly stressed.

[0042] In some embodiments, the backing 20 may be made of reverse-adhesive waterproofing membrane to provide it with a certain strength to prevent the backing 20 from sinking and deforming inward during the concrete pouring process.

[0043] In some embodiments, please refer to Figure 2a , 2b The diameter of the hole on the backing 20 for passing the pipe 50 is smaller than the diameter of the pipe 50 to ensure that the backing 20 can fit tightly against the surface of the pipe 50.

[0044] In some embodiments, the inner support bar 30 and the back rib bar 40 can be made of the leftover material of the hole template 10, which can save materials on the one hand, and make the thickness of the inner support bar 30 the same as that of the hole template 10 on the other hand, so as to ensure that the casting surface of the backing 20 and the hole template 10 are flush. The materials used in the present invention are relatively common at the construction site, easy to obtain, and can use some of the construction leftovers, which is green and environmentally friendly.

[0045] In some embodiments, the back ribs 40 can be installed on the outer facade of the hole template 10 by nails, so that the back ribs 40 are firmly connected to the hole template 10.

[0046] Please continue to refer to Figures 1a to 4b The present invention also provides a construction method for the formwork structure of the group pipe through-wall opening as described above, comprising the following steps:

[0047] Step 1: When the template is set up, the opening template 10 is set according to the position of the pipeline 50, so that each pipeline 50 passes through the reserved hole 11 in the middle of the opening template 10, such as Figure 1a , 1b shown.

[0048] Step 2: If Figure 2a , 2bAs shown, according to the diameter and position of the pipe 50, holes of corresponding size and position are opened on the backing 20 to facilitate the subsequent pasting of the backing 20; when pasting the backing 20, the size of the backing 20 should be larger than the size of the reserved hole 11 to facilitate the subsequent installation of the inner support bar 30, while preventing leakage of slurry from the edge of the reserved hole 11 or damage to the backing 20.

[0049] Step 3: In the reserved hole 11, the inner support bar 30 is installed in the gap between the hole template 10 and the pipe 50 to support the casting surface of the backing 20 and the hole template 10 to be located in the same plane, such as Figure 3a , 3b The length and quantity of the inner support bar 30 can be freely adjusted according to the distance between the pipes 50, and the gap between the pipes 50 and the opening template 10 should be covered as much as possible to ensure the flatness of the concrete pouring surface.

[0050] Step 4: Lay the backing strips 40 around the pipe 50 on the outer surface of the opening template 10, such as Figure 4a , 4b The size of the backing strips 40 should be adjusted according to the intervals between the pipes 50 so that the area between the pipes 50 can be reinforced; the number of the backing strips 40 should be adjusted according to the size of the reserved opening 11 and the backing 20, and the entire area of ​​the backing 20 should be reinforced as much as possible to prevent the backing 20 from being damaged during the concrete pouring process.

[0051] Step 5: After the concrete strength reaches the demolding strength, the formwork is removed and the uneven concrete around the pipe 50 is cleaned to facilitate the construction of subsequent projects.

[0052] The above method is applicable to wall-penetrating pipes of different shapes and sizes, causes less damage to the template, and can be reused.

[0053] In summary, the present invention provides a formwork structure for a group of pipe-through-wall openings and a construction method thereof, wherein the formwork structure includes: a hole-opening template 10, wherein each pipe 50 passes through a reserved hole 11 of the hole-opening template 10; a backing 20, which is laid in the reserved hole 11, and on the side where the casting surface is located, the backing 20 and the hole-opening template 10 are located in the same plane; the edge of the backing 20 extends into the reserved hole 11 and is pasted on the outer facade of the hole-opening template 10; an inner support bar 30, which is supported in the reserved hole 11 between the backing 20 and the pipe 50 and between the pipes 50 to provide sufficient support for the backing 20; and a back rib 40, which is installed on the outer facade of the hole-opening template 10 and is interspersed between the pipes 50 around the reserved hole 11 to reinforce the entire formwork structure. The present invention adopts a method of supporting formwork by blocking from the outside, and there is no need to cut the formwork according to the shape of the group of pipes. The construction operation is simple and quick, and the concrete pouring quality is good.
