Description

Positioning device for pre-buried wire box in prefabricated concrete component

Technical Field

The utility model relates to a prefabricated technical field of assembled, concretely relates to positioner of pre-buried line box among assembled concrete prefabricated component.

Background

The prefabricated concrete structure is a structural form which accords with an industrial production mode, has the obvious advantages of short construction period, low labor intensity, low material consumption, small environmental pollution and the like, and is beneficial to improving the building quality and protecting the environment. The construction quality of the fabricated concrete structure depends on the quality of the prefabricated parts, the quality of the connection nodes, construction installation deviation, etc., which are prerequisites. At the present stage, the production of the domestic prefabricated parts is in an accelerated development stage, the technical level of manufacturers is uneven, the control of the appearance quality and the size deviation of the prefabricated parts is very insufficient, and particularly the deviation requirements of the horizontal +/-10 mm and the vertical-5-0 mm in the technical standard for the prefabricated concrete construction GB/T51231-. In this respect, the "fail" in the form test or the approach test of the component is made; on the other hand, this will cause trouble in the later installation of the water and electricity of the house and eventually affect the use function of the house. Therefore, the embedded wire box must be accurately positioned and fixed.

The method adopted at present is to fix the template by iron nails or bind and fix the template by iron wires and steel bars, and in addition, in order to prevent concrete from entering the embedded wire box, the interior of the embedded wire box needs to be blocked. However, in the actual situation, the binding of the wire box is loosened probably in the concrete vibration process, so that the embedded wire box deviates from the horizontal direction and floats upwards in the vertical direction, and the position deviation of the embedded wire box after final forming cannot meet the standard requirement.

Chinese patent document CN208601709U proposes "positioning device for embedded lamp box in assembled composite slab" to realize accurate positioning and effective fixation of embedded lamp box, but there are some defects: 1. the device needs to open a hole in the middle of the box top so that a screw rod can extend into the box top, but the box top is not provided with holes or 4 holes which are uniformly distributed and are easy to form, so that the hole is opened in the middle of the box top very difficultly, and in addition, the concrete is easy to pollute when vibrated; 2. the device adopts the bolt and the nut to limit the lamp box in the vertical direction, so that the screw and the nut are easily stained with concrete slurry to cause that the lamp box cannot be disassembled; 3. the device hangs from the steel mould platform at prefabricated component after, adsorbs to the magnetic base adsorption affinity of steel mould platform is strong, dismantles and wastes time and energy.
