Description

Pipeline fixer

Technical Field

The invention belongs to the technical field of pipeline fixing in building construction, and particularly relates to a pipeline construction fixing device for a weak current household box.

Background

In the early stage of building electrical engineering, in the stage of embedding the electrical pipelines, the disordered arrangement state of the pipelines often appears; especially, when the electrical pipelines are bent and are perpendicular to the floor slab, the arrangement is very disordered at the beginning, the pipelines have certain strength, and a part of the pipelines are rebounded after bending, so that the distance and the extension direction of the pipelines are uneven, the pipelines are easy to deviate in the subsequent concrete pouring, great difficulty is caused for the connection of the subsequently installed weak current household boxes, and the pipelines are difficult to manufacture and survive once; even a mode of secondary pipe connection and box feeding is adopted, so that material and labor waste is caused, and the risk of pipe blockage is easily caused by adding a pipe joint in the shear wall.

In addition, some pipeline fixing devices need to drill holes on each casing pipe, and the positions of the pipeline fixing devices are fixed through screws, namely the cylindrical cambered surface of the PVC pipe and the conical shape of the screw, so that the operation is very inconvenient, and great inconvenience is brought to construction.

Furthermore, in the past, before concrete pouring, each pipeline is sleeved with a buckle cover, so that the blockage caused by scattering in the concrete pouring process is avoided, and time and labor are wasted.

Detailed Description

The most critical place for the positioner 1 of the present invention is to position the pipeline accurately. Before concrete is poured on the building floor, the pipelines are bent to be vertical to the floor after the pipelines on the floor are arranged, and the pipelines 9 need to be strictly arranged at intervals. The steel bar is used as a framework and is designed into an upper-layer frame structure 2 and a lower-layer frame structure 2, a plurality of sleeves 3 are welded on the frame structure 2 of each layer, and plugging caps 4 are arranged in the sleeves 3 of the upper layer; the distance between each casing 3 is consistent, and each casing 3 of the upper and lower layers corresponds to each other, so that the position of each pipeline is approximately consistent, as shown in fig. 1 and 2.

After the pipeline 9 is bent to a position vertical to the floor surface, the sleeve 3 on the positioner 1 passes through the pipeline, and the steel strands 5 at two ends are bound on the nearby floor steel bars for fixing. The weak current household boxes 8 can be arranged in a plurality of rows, generally arranged in two rows, the invention is arranged in two rows, pipelines in each row are not equal, and the invention is arranged in 4 rows. The former worker is simple in operation, only one welding point is electrically welded on the upper row of sleeves 3 and the lower row of sleeves 3, the welding point is arranged at the position where the reinforcing steel bars 2 are contacted with the sleeves 3, and the falling-off condition is always found in the practical process. From the mechanical point of view, each sleeve 3 is only welded at the edge and is not firm, so the auxiliary steel bars 10 are also welded between the two rows of sleeves 3, and thus, the two welding points balance the stress of the sleeves 3 and keep the strength.

Each sleeve 3 on the lower layer is 3-8 cm in length and mainly plays a role in limiting, and the line pipe 9 penetrates through the sleeves 3 and is approximately consistent in range within a certain distance. Each sleeve 3 on the upper layer is 5-12 cm in length and slightly longer than the sleeve 3 on the lower layer, because the sleeve 3 on the upper layer is internally provided with a plugging cap 4 with a certain length, generally 4-8 cm, and the plugging cap 4 is internally provided with a limiting groove 7, as shown in figure 4.

The previous fixator 1 is of a single-layer structure, holes need to be drilled in the sleeve 3 of the fixator 1, as shown in the attached drawing 3, after the sleeve is sleeved with the pipeline 9, accurate positioning is needed, because the pouring force easily deflects the pipeline when concrete is poured, and after the concrete is solidified, the subsequent installation of the weak current household box 8 is very laborious, and secondary treatment often occurs, so that the bolt 6 is tightened to the pipeline 9 to enable the pipeline to be located at the center position in the sleeve 3.

In the invention, the plugging cap 4 is arranged in the upper-layer sleeve 3, the limiting groove 7 is arranged in the plugging cap 4, and the pipeline 9 is inserted into the limiting groove 7 in the plugging cap 4, so that drilling on the sleeve 3 is saved, and the step of fixing the pipeline 9 by the screw 6 is also saved. Since the pipe line 9 is a cylindrical arc surface and the screw 6 is a cone, the fixation is difficult, so the invention is very easy in the process operation. Meanwhile, each pipeline needs to be plugged after the former pipeline 9 is fixed, so that residues are prevented from entering the pipeline 9 to plug the pipeline in the concrete pouring process.

The height of the double-layer frame structure 2 formed by welding and fixing the steel bars is the distance between the floor surface and the weak current household box. The double-layer frame structure 2 is made of excess materials and leftover materials of reinforcing steel bars, the double-layer frame structure 2 and the auxiliary reinforcing steel bars 10 are made of excess material stubs, and the total length of the fixer 1 is less than 40-60 cm, the height is 20-30 cm, and therefore the excess materials and the leftover materials are completely used. The JDG pipe with the diameter of 25 or 32mm is made of a corner waste material, the length of the JDG pipe is 3-12 cm, and the plugging cap 4 is made of a PVC material and is also made of a corner excess material plug of a wire pipe, so that the manufacturing cost is greatly reduced.

The holder 1 can be reused 7. After the pipelines 9 are bent and vertical to a floor slab, each pipeline 9 penetrates through the sleeve 3, the fixator 1 is tightly bound through the steel strand 5, each pipeline 9 is limited and fixed through the limiting groove 7 in the plugging cap 4 in the upper-layer sleeve 3, at the moment, concrete pouring is started, and after concrete is solidified and formed, the position of the weak current household box 8 is designed, as shown in the attached drawing 5. Before the weak current household separation box 8 is installed, the steel strand 5 can be untied from the nearby steel bars, the whole fixer 1 with the double-layer frame structure is detached, and the next recycling can be realized.

In conclusion, by adopting the technical scheme of the invention, although a small amount of cost is increased in the pre-burying stage, the primary survival rate of the line pipe is improved when the weak current branch box 8 is pre-buried and installed, if the lengths of the reserved line pipes are consistent, the primary survival can be realized, and the step of secondary pipe connection is omitted (which is easier to realize through practical practice). The joints of the embedded pipelines are reduced by avoiding secondary connection, so that the risk of pipe blockage can be avoided, and part of labor cost is saved. By adopting the measures, the survival effect is obviously improved, common quality problems such as deviation of the line pipes, different lengths of reserved line pipes, untight plugging of the line pipes and the like which are easy to occur at the positions of the household boxes are avoided, and the rework cost for maintaining the wall body grooving at the later stage is indirectly saved.
