The utility model discloses realize having enough to meet the need the use, easy operation simultaneously, construction convenience.
Description
Technical Field
The invention belongs to the field of civil buildings and production, and particularly relates to a retention of a reserved hole of a civil building, production and living water supply and drainage pipeline.
Background
The construction of a reserved hole in the traditional construction is to process a handle at the upper part of a section of steel pipe and weld a cross-shaped steel bar at the lower part. When the hole reserving sleeve is used, a hole needs to be formed in the template, and the hole reserving sleeve is fixed on the template at the position needing to be reserved. And when the concrete is initially set, pulling out the sleeve pipe of the reserved hole, and reserving the hole opening.
The method has the following disadvantages:
1. the concrete surface layer around the reserved hole is easy to damage because the concrete is not solidified before the sleeve of the reserved hole is pulled out. But also causes uneven section at the reserved hole or insufficient thickness of concrete at the periphery of the hole opening.
2. The reserved hole sleeve pipe is pulled out too late, the concrete is completely solidified, the reserved hole sleeve pipe cannot be pulled out, secondary cutting is needed, materials are wasted, and labor cost is increased.
Disclosure of Invention
The invention provides a recyclable reserved hole prefabricating special tool which is easy to process materials, simple to operate and capable of ensuring construction quality.
The technical scheme of the invention is as follows: a reusable prefabricated special tool for reserved holes is characterized by comprising a cylinder, an upper template, a lower template, a mountain-shaped clamp and a threaded rod, wherein holes with the diameter of 18mm are formed in the axes of the upper template and the lower template, a through seam from top to bottom is formed in the side wall of the cylinder, and a hook is arranged at one end of the threaded rod; the other end of the threaded rod is provided with threads; the upper template is positioned above the cylinder, the lower template is positioned below the cylinder, the threaded rod penetrates through the upper template, the cylinder and the lower template, the hook end of the threaded rod is positioned below the lower template, and the threaded end of the threaded rod is positioned above the upper template and is fastened with the mountain-shaped clamp in a threaded connection mode.
The upper template is a square plate with the thickness of 150mm x 150 mm.
The lower template is a template (300X 300 mm)
The cylinder diameter is 100mm, and the length is 200 mm.
The threaded rod penetrating through the wall and the hook are welded into a 250mm combined body, a hole with the diameter of 18mm is drilled in the middle of an upper template with the diameter of 150mm x 150mm, and a UPVC drainage pipe with the diameter of 100mm is cut along a vertical axis. During construction, the UPVC pipe is vertically placed on a lower template with a laid line, a hole with the diameter of 18mm is punched in the center of a pipeline on the lower template, a 150 mm-150 mm template is covered on the pipeline, a processed combined body vertically penetrates through the two holes, a hook is hooked downwards, and a mountain-shaped clamp is used for fastening a wall penetrating threaded rod on the combined body.
The utility model discloses application method: before concrete pouring, the lower template is placed below the binding pouring steel bars, the cylinder is placed above the binding pouring steel bars, the upper template covers the cylinder, and the threaded end of the threaded rod sequentially penetrates through the lower template, the cylinder and the upper template to be connected and fastened with the mountain-shaped card; and pouring concrete, compacting the concrete by vibration, removing the mountain-shaped clamp and the upper template after final setting, and bending the sleeve pipe inwards along the through seam to take out.
Adopt the utility model discloses the advantage is in need not pulling out the reservation hole sleeve pipe before the concrete solidifies. Therefore, the flatness of the concrete surface layer around the reserved hole is effectively guaranteed. And because the surface of the UPVC pipe is smooth and the short pipe is axially split, the pipe diameter can be reduced, and the UPVC pipe can be easily taken out even if the concrete is solidified.
Meanwhile, people pay more attention to the environmental protection, and from the aspect of national sustainable development, the invention can use the waste materials and excess materials on the site to the maximum extent, so that each material can have higher utilization rate, the turnover use is realized to the maximum extent, and meanwhile, the operation is simple and the construction is convenient.
