Description

Technical Field

[0001] The utility model relates to the field of building construction, and particularly relates to an installation tool for embedded pipelines. Background Art

[0002] In the traditional process, the pipe orifices of the embedded pipelines reserved on the beams and slabs are directly drilled at the corresponding positions on the bottom formwork of the constructed structure and the beam formwork, and then the pipe orifices of the return pipelines are inserted and fixed in the drilled holes. The traditional method of installing the return pipelines is efficient and convenient, but there are some problems as follows:

[0003] 1. On the formwork, drilling holes will cause irreversible damage, resulting in a multiple reduction in the utilization rate of the formwork; moreover, a large amount of sawdust and construction waste are generated during drilling. Not only is it difficult to clean, but the holes are not tightly sealed and leakage of slurry occurs, which will cause poor quality of the formed concrete.

[0004] 2. The existing embedded pipelines are not accurately embedded, and misalignment occurs during the construction process. When correcting the deviation of the pipeline in the later stage, it is necessary to chisel the concrete, which not only generates a large amount of construction waste, but also causes varying degrees of damage to the structure.

[0005] 3. The length of the embedded pipeline inserted into the hole is too long. When secondary pipe fitting is required, a section of the embedded pipeline needs to be cut off and then connected, resulting in waste of materials.

[0006] Therefore, it is necessary to provide an installation tool for embedded pipelines that does not require drilling holes in the formwork, accurately embeds the pipelines, and saves the pipelines. Summary of the Invention

[0007] In view of the above deficiencies of the prior art, the utility model provides an installation tool for embedded pipelines.

The left and right sides of the pipe fitting main body are respectively fixed with a left mounting plate and a right mounting plate. Mounting holes are provided on both the left mounting plate and the right mounting plate. A front buckle protrusion is provided on the front side of the bottom of the pipe fitting main body, and two rear buckle protrusions are provided on the rear side of the bottom of the pipe fitting main body. The two rear buckle protrusions form a bayonet that cooperates with the front buckle protrusion, and the front buckle protrusion is in snap-fit with the two rear buckle protrusions.

[0009] Further, front side protrusion extension parts are provided on both sides of the front buckle protrusion, and the height of the front side protrusion extension parts matches the height of the rear buckle protrusions.

[0010] Further, an arc part is provided on the front side of the front buckle protrusion, and the arc part fits the outer contour of the pipe fitting main body.

[0011] Furthermore, a number of reinforcing ribs are provided between the top of the left mounting plate and the pipe fitting body, and between the top of the right mounting plate and the pipe fitting body. The reinforcing ribs are triangular.

[0012] Furthermore, clamping inclined surfaces are provided on the opposite sides of the two rear snap protrusions, and both of the two clamping inclined surfaces are arranged facing inwards.

[0013] Furthermore, arc transition parts are provided between the pipe fitting body and the left mounting plate, and between the pipe fitting body and the right mounting plate.

[0014] Furthermore, the pipe fitting body, the left mounting plate and the right mounting plate are integrally cast and formed.

[0015] Furthermore, the pipe fitting body, the left mounting plate and the right mounting plate are all made of plastic materials.

[0016] The beneficial effects of the present utility model are as follows:

[0017] For the installation work of the present utility model, the installation tooling is installed inside the formwork, that is, on the side where the formwork is poured with cement, and then the embedded pipeline is connected to the pipe fitting body of the installation tooling, so that the installation tooling, the formwork and the embedded pipeline together form a closed space. After the concrete is poured and completed, the formwork is disassembled, and the embedded pipe orifice is naturally formed, completing the installation of the embedded pipeline. Finally, the installation tooling is removed.

[0018] For the installation method of the embedded pipeline of the present utility model, there is no need to open holes on the formwork, no sawdust is generated, and the integrity of the formwork will not be affected, effectively ensuring that the formwork can be reused later.

[0020] The embedded pipeline of the present utility model can be adjusted to be connected to the installation work, not too many embedded pipelines will be generated, and at the same time, there is no need to cut off the redundant embedded pipelines later, making the installation of the embedded pipelines more efficient.

[0021] The present utility model allows the pipeline embedding and the formwork installation work to be carried out simultaneously, avoiding a series of problems caused by secondary hole opening after the formwork is installed, thereby improving the convenience of the pipeline embedding construction, ensuring the concrete forming quality, and avoiding the waste of materials and labor.

[0022] The installation work of the present utility model can realize the construction of the embedded pipeline in one forming, improve the formwork life, reduce the generation of sawdust and construction waste, improve the reserved precision of the embedded pipe orifice, reduce the labor cost, save the construction period, and is environmentally friendly.

[0030] As Figure 1 、 2 and shown in 3, the installation tool for pre-buried pipelines includes a tubular pipe fitting main body 1. The left and right sides of the pipe fitting main body 1 are respectively fixed with a left mounting plate 2 and a right mounting plate 3. Mounting holes 4 are provided on both the left mounting plate 2 and the right mounting plate 3. A front buckle projection 5 is provided on the front side of the bottom of the pipe fitting main body 1, and two rear buckle projections 6 are provided on the rear side of the bottom of the pipe fitting main body 1. The two rear buckle projections 6 form a bayonet 61 that cooperates with the front buckle projection 5, and the front buckle projection 5 is in clamping cooperation with the two rear buckle projections 6. Adjacent installation tools can be connected side by side through the front buckle projection 5 and the bayonet 61, so that the installation tool can meet the installation of pre-buried pipelines distributed in rows.

[0031] In this embodiment, front side projection extensions 52 are provided on both sides of the front buckle projection 5, and the height of the front side projection extensions 52 matches the height of the rear buckle projection 6. There is a certain gap between the front side projection extensions 52 and the rear buckle projection 6, and in the form of line contact, it can better cooperate with the front buckle projection 5 and the bayonet 61 to achieve connection. At the same time, the buckle projection 5 and the bayonet 61 are convenient for disassembly and separation, as Figure 4 。

[0032] In this embodiment, an arc portion 51 is provided on the front side of the front snap projection 5, and the arc portion 51 is fitted to the outer contour of the pipe fitting body 1.

[0033] In this embodiment, a plurality of reinforcing ribs 7 are provided between the top of the left mounting plate 2 and the pipe fitting body 1, and between the top of the right mounting plate 3 and the pipe fitting body 1. The reinforcing ribs 7 are preferably triangular reinforcing rib plates. There are two reinforcing ribs 7 provided on both the left mounting plate 2 and the right mounting plate 3, which not only improves the strength of the left mounting plate 2 and the right mounting plate 3, but also makes the force on the left mounting plate 2 and the right mounting plate 3 more uniform.

[0034] In this embodiment, clamping inclined surfaces 62 are provided on the opposite sides of the two rear snap projections 6, and both of the two clamping inclined surfaces 62 face inward. The front snap projection 5 and the two rear snap projections 6 form a clamping fit. The two clamping inclined surfaces 62 in an inner V shape can better play a clamping role, so that adjacent installation tools are stably limited in the radial direction of the pipe fitting body 1.

[0035] In this embodiment, arc transition portions are provided between the pipe fitting body 1 and the left mounting plate 2, and between the pipe fitting body 1 and the right mounting plate 3. The arc transition portions can better avoid stress concentration at the joints between the pipe fitting body 1 and the left mounting plate 2 and the right mounting plate 3.

[0036] In this embodiment, the pipe fitting body 1, the left mounting plate 2 and the right mounting plate 3 are integrally cast, so that the connection strength between the pipe fitting body 1, the left mounting plate 2 and the right mounting plate 3 is better. The pipe fitting body 1, the left mounting plate 2 and the right mounting plate 3 are all made of plastic. The embedded pipeline only needs to be connected and positioned. The installation tool made of plastic is convenient for production and manufacturing, has low cost, and is light in weight and easy to carry.

[0037] Working process and principle: The specific construction process of the installation tool for the embedded pipeline is as follows:

[0038] S1. First, perform pipe orifice marking and positioning: According to the construction drawing, use a tape measure to measure the position of the pipe fitting to be embedded at the embedded position and make a "cross" mark with a marker pen;

[0039] S2. Select the appropriate number and specifications of installation tools: Select the corresponding specifications of special pipe fittings according to the different circuit layouts in the construction drawing;

[0040] S3. Assemble and join the installation tools: Place the front snap projection 5 of the installation tool to be combined opposite to the bayonet 61, hold one with one hand and keep it still, turn the bayonet 61 of the installation tool outward, align the front snap projection 5 of another installation tool with the bayonet 61 vertically from top to bottom and push it until the bottoms of the two installation tools are flush, that is, the special pipe fitting is assembled, as Figure 4 shown;

[0041] S4. Fixing of the installation tooling: Place the assembled installation tooling combination according to the positioning dimensions, and fix the assembled installation tooling in the corresponding position. Specifically, use formwork nails to nail in the installation holes 4 to fix the installation tooling on one side of the formwork where the cement is to be poured.

[0042] S5. Rechecking and inspection of the installation tooling: Use a tape measure to recheck whether the installation position of the pipe fittings is offset, and correct it in time if there is an offset.

[0043] S6. Connection of the embedded pipeline: When installing the formwork, directly connect the embedded pipeline to the pipe fitting body 1 of the installation tooling to form a closed space together with the formwork. After the concrete is poured and completed, remove the formwork, and the embedded pipe orifice will be naturally formed to complete the installation of the embedded pipeline. Finally, remove the installation tooling.
