Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a device for preventing electric wire pipes from being damaged by drilling. Background Art

[0002] During the construction process, the installation of supports and hangers is a common construction step. However, when installing supports and hangers, drilling operations may damage the wire pipes, causing unnecessary trouble and safety hazards to the construction. When laying wire pipes on traditional reinforced concrete cast-in-place slab formwork, there are two common methods to avoid damaging the wire pipes when drilling holes for supports and hangers in the later stage: the first is to deepen the installation path of the wire pipes in the drawings, and strictly follow the detailed drawings during construction. In the later installation and decoration stage, when drilling holes on the top plate, the wire pipes can be avoided according to the detailed pipeline installation path diagram; the second is to use special paint to mark the positions of the wire boxes and wire pipes on the template in advance when installing on the template. After the demolding is completed, the installation path will be displayed on the bottom of the cast-in-place concrete slab, and the installation position will be clear at a glance. However, the above traditional methods to avoid damaging the wire pipes are difficult to implement when the floor is designed as a reinforced truss floor deck structure. Utility Model Content

[0003] The utility model aims to solve the deficiencies of the prior art and provide a device to prevent the electric wire tube from being damaged by drilling.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a device for avoiding damage to electric wire pipes by drilling, comprising a foam board pad, a metal sheet, and a T-shaped plug rod, the pre-buried water and electricity electric wire pipes are fixed on the foam board pad, and a bent metal sheet is arranged at the corner position of the pre-buried water and electricity electric wire pipe and near the pre-buried wire box, the metal sheet is placed above the pre-buried water and electricity electric wire pipe, both ends of the metal sheet are provided with a first circular hole, and a second circular hole is provided at a corresponding position of the galvanized iron sheet of the steel truss floor deck, two of the T-shaped plug rods pass through the first circular hole and the second circular hole, the bottom of the T-shaped plug rod passes through the galvanized iron sheet of the steel truss floor deck to expose a certain length of the steel bar head, and the pipeline installation boundary pops up between the corresponding steel bar heads of the two groups of devices.

[0005] Furthermore, the metal sheet is an aluminum sheet with a thickness of 0.2 mm.

[0006] Furthermore, the radius of the first circular hole and the second circular hole is 5 mm.

[0007] Furthermore, the T-shaped rod is welded from steel bars with a diameter of 4 mm.

[0008] The beneficial effect of the utility model is that when the floor is designed as a steel truss floor deck structure, the utility model can effectively determine the pipeline installation boundary according to the position of the steel bar head before drilling holes in the support and hanger. When drilling holes in the support and hanger, the range marked by the pipeline installation boundary is avoided, that is, while ensuring construction safety, damage to the electric wire pipe can be effectively avoided, thereby improving construction efficiency and quality.

[0014] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0015] like Figure 1-2 As shown, a device for preventing electric wire pipes from being damaged by drilling is characterized in that it comprises a foam board pad 1, a metal sheet 2, and a T-shaped plug rod 3. A pre-buried water and electricity electric wire pipe 4 is fixed on the foam board pad 1. A bent metal sheet 2 is arranged at the corner position of the pre-buried water and electricity electric wire pipe 4 and near the pre-buried wire box 5. The metal sheet 2 is placed above the pre-buried water and electricity electric wire pipe 4. First circular holes 6 are provided at both ends of the metal sheet 2. A second circular hole 8 is provided at a corresponding position of the galvanized iron sheet 7 of the steel truss floor deck. Two T-shaped plug rods 3 pass through the first circular hole 6 and the second circular hole 8. The bottom of the T-shaped plug rod 3 passes through the galvanized iron sheet 7 of the steel truss floor deck to expose a certain length of steel bar head 9. A pipeline installation boundary 10 is popped out between the corresponding steel bar heads 9 of the two sets of devices. The pipeline installation boundary 10 is determined according to the steel bar head 9, and the range of the pop-up line between the two pipeline installation boundaries 10 cannot be used for drilling operations.

[0016] The metal sheet 2 is an aluminum sheet with a thickness of 0.2 mm.

[0017] The radius of the first circular hole 6 and the second circular hole 8 is 5 mm.

[0018] The T-shaped rod 3 is welded from steel bars with a diameter of 4 mm.

[0019] The use process of the utility model is as follows: fix the embedded water and electricity wire pipe 4 on the foam board pad 1, use bending equipment to bend the metal sheet 2, and use hole punching equipment to punch holes at both ends, and punch holes on the galvanized iron sheet 7 of the steel truss floor deck according to the position of the pipeline corner and the position of the embedded wire box 5, make a T-shaped plug rod 3 with steel bars, and use the T-shaped plug rod 3 to fix the metal sheet 2, ensuring that the T-shaped plug rod 3 is exposed to a certain length of the galvanized iron sheet 7 of the steel truss floor deck. After the above steps are completed, during the installation and decoration stage, according to the position of the steel bar head 9, use the line springing equipment to pop out the pipeline installation boundary 10, and when drilling holes in the support bracket, avoid the line springing range, so as to avoid damaging the wire pipe and causing unnecessary trouble and safety hazards to the construction.
