Description

Technical Field

[0001] The invention relates to building construction, in particular to a construction method for secondary structure distribution box lintel pipelines without grooving. Background Art

[0002] In the construction of secondary structure distribution box pipelines, in order to ensure the stability of the masonry wall, the common practice is to set a prefabricated concrete lintel under the masonry wall, and then groove and chisel the lintel. The grooving of the prefabricated lintel affects the integrity of the prefabricated lintel, causes certain damage to the strength of the lintel, reduces the safety of the structure to a certain extent, increases the difficulty coefficient of edge closing, and the plastering at the groove is prone to hollowing and cracking, resulting in quality problems. This type of construction method not only affects the structural safety and visual quality, but also generates a large amount of construction waste in the later stage, adding additional costs to the construction. Summary of the invention

[0003] The present invention aims to solve the above technical problems, thereby providing a construction method for secondary structure distribution box lintel pipelines without grooving, reducing the amount of grooving, improving structural safety, and improving construction quality.

[0004] The present invention solves the technical problem and adopts the following technical solution: A construction method for a secondary structure distribution box lintel pipeline without slotting, comprising the following steps: S1. Formwork to make prefabricated lintels The sides of the precast lintel are provided with grooves; S2. Build the wall, place the prefabricated lintel at the specified position, with the groove facing the reserved hole of the distribution box, and install the insulation board in the groove; S3, pipeline grooving Take out the insulation board and groove the pipeline; S4. After the slotting is completed, put the insulation board back; S5. Finishing the surface with plastering.

[0005] Compared with the prior art, the present invention using the above technical solution has the following beneficial effects: 1) Reduce the problem of excessive slotting of prefabricated lintels, improve structural safety and visual quality, and improve construction quality; 2) Reduce workload, improve construction efficiency and reduce construction costs; 3) It reduces the later repair work, reduces the generation of construction waste and saves resources.

[0006] Further, the optimization scheme of the present invention is: The thickness of the prefabricated lintel is smaller than the thickness of the wall.

[0007] The length of the groove is adapted to the width of the reserved hole of the distribution box.

[0008] The thermal insulation board is an extruded polystyrene board.

[0009] The outer side surface of the insulation board is flush with the outer wall surface of the wall. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] See also Figure 1 , Figure 2 This embodiment provides a construction method for a secondary structure distribution box lintel pipeline without grooving, which is carried out in the following steps: S1. Formwork to make prefabricated lintels The formwork is supported and the concrete precast lintel 1 is poured. The thickness of the precast lintel 1 is less than the thickness of the wall 2. A groove is provided on the side of the precast lintel 1. The length of the groove is adapted to the width of the reserved hole 4 of the distribution box.

[0015] S2. Build a wall 2 using blocks. Reserve a hole 4 for the distribution box on the wall 2. Place a prefabricated lintel 1 at a specified position. The groove faces the hole 4 for the distribution box. An insulation board is pasted in the groove. The insulation board uses an extruded polystyrene board 3. The outer side of the extruded polystyrene board 3 is flush with the outer wall surface of the wall 2.

[0016] S3, pipeline grooving Before the pipeline is grooved, the extruded polystyrene board 3 is first taken out from the groove of the prefabricated lintel 1, and then the pipeline is grooved.

[0017] S4. After the grooving is completed, put back the extruded polystyrene board 3 and place the extruded polystyrene board 3 in the groove of the prefabricated lintel 1.

[0018] S5. Finishing the surface with plastering.
