Description

Concrete floor hole to be provided device

One, technical field:

The utility model relates to a kind of building utensil, particularly a kind of concrete floor hole to be provided device.

Two, background technology:

At present, the floor slab construction of highrise building often adopts monobloc cast steel concrete technology, and pipeline passways such as the water up and down of floor, natural gas, power supply must be reserved, and conventional method is the processing template, make built-in fitting in advance, or directly be embedded in the concrete with one section pvc pipe.Time-consuming the taking a lot of work that these methods have, built-in fitting can't be reused, and causes a large amount of wastes; The location in building that has is inaccurate, brings inconvenience for the later stage installation, deals with improperly and will later stage floor construction, pipeline installation quality be caused a hidden trouble.Utility model patent CN2893057Y proposes a kind of building pipe hole to be provided sleeve pipe, and this utility model main body is a pillar, and pillar inwall inboard is provided with plurality of strengthening ribs, pillar osculum end is provided with bottom, big opening end is provided with gag, and the inboard of bottom is provided with the raised line of right-angled intersection, and raised line is provided with the nail hole.This utility model can realize industrialization, standardized production, need not field machining, can reuse after removing after each construction.But there is complex structure in this utility model, and production and processing cost height is installed problems such as inconvenient, the easy skew in location.

Three, utility model content:

Technical problem to be solved in the utility model is: overcome weak point of the prior art, provide a kind of simple in structure, with low cost, easy for installation, the concrete floor hole to be provided device of accurate positioning.

The technical solution of the utility model is:

A kind of concrete floor hole to be provided device, contain sleeve pipe and fixed mechanism, sleeve pipe is provided with base plate base plate center and establishes securing member, at least be provided with two screw holes on the base plate, tightening up bar one end cooperates fixing with the base plate central fastener, tighten up bar and pass cover central hole, and cooperate, tighten up the bar other end and be fixed with handle with fastener on the cover plate.

The cross sectional shape of sleeve pipe is circular.

Base plate and casing profile form fit, base plate are circular, square, rectangle, and cydariform, cross is chosen any one kind of them in the approximate equilateral triangle.

Cover plate is laid the sleeve pipe upper end, and cover plate is shaped as circle, and is square, rectangle, and cross is chosen any one kind of them in the approximate equilateral triangle.

Cover plate stretches out the outer part of sleeve pipe and is provided with downward flanging.

The beneficial effects of the utility model are:

1, simple in structure: the utility model is provided with sleeve pipe and fixed mechanism, and it is few to relate to parts, cooperates by movable between parts, and securing member is fixed, use, the maintenance cost of greatly reducing simple in structure.

2, with low cost: concrete floor hole to be provided device of the present utility model, processing method is simple, and selection standard spare cuts, welding, mantle fiber can be finished, and need not to redesign mould, and punch process is cheap for manufacturing cost.

3, easy for installation: the utility model in use, first fixed base plate overlaps tubing again, uses anchorage bar and cover plate fixed sleeving at last, installation steps are simple, general constructor all can carry out fitting operation.

4, accurate positioning: the utility model in use, at first fixed base plate is positioned on the template, overlaps tubing again, guarantee that like this sleeve pipe position location is accurate with screw, improve the accurate position of concrete pouring quality and hole to be provided, guaranteed later stage installation procedure efficient.

5, cover plate is provided with flanging, increases the integral rigidity and the safety in utilization of device.

Five, the specific embodiment:

Embodiment one: referring to Fig. 1, Fig. 2, and among the figure, the 1-sleeve pipe, the 2-base plate, the 3-cover plate, 4-tightens up bar, 5-handle, 6-base plate clamp nut, 7-cover plate clamp nut, 8-bottom plate screw hole.

Concrete floor hole to be provided device, sleeve pipe 1 is provided with base plate 2 base plate centers and establishes clamp nut 6, at least be provided with two screw holes 8 on the base plate 2, tightening up bar 4 one ends cooperates fixing with base plate center clamp nut 6, tighten up bar 4 pass cover plate 3 centre bores and with cover plate 3 on tighten up nut 7 and cooperate, tighten up bar 4 other ends and be fixed with handle 5.The cross sectional shape of sleeve pipe 1 is circular, and base plate 2 is circular and sleeve pipe 1 cross sectional shape coupling, and cover plate 3 is shaped as rectangle, stretches out the outer part of sleeve pipe and is provided with downward flanging.

During actual the use, at first be screwed into template with screw by the bottom plate screw hole and fix base plate in the hole to be provided position, casing pipe sleeve is contained on the base plate, tighten up bar and put on cover plate, be screwed to correct position, be screwed in the nut that is fixed on the base plate center and tighten up tightening up bar one end tightening up nut, mix up the position of cover plate on sleeve pipe then, tighten downwards and tighten up nut on the cover plate, make cover plate be fixed sleeve pipe, can carry out concreting at the bushing outer surface coating release agent after the installation of hole to be provided device.After the concrete setting, unclamp and tighten up nut and cover plate on the cover plate, with tightening up the taking-up that gets loose the nut of bar from base plate, pull out sleeve pipe, the screw on the base plate that comes loose takes out base plate, reuses after each parts is cleaned.
