Description
Technical field
The present invention relates to a kind of gage controller, particularly, relate to a kind of controller that can accurately control steel bar concrete cast-in-place plate negative reinforcement protective layer thickness and cast-in-place plate thickness.
Background technology
At present, enterprise in charge of construction is an insoluble a great problem in the construction to the control of reinforced concrete cast-in-situ plate top reinforcement (negative reinforcement) topping and the control of cast-in-place plate thickness always.Following substantially several according to working measure now:
One, the control of top mat sheet
1, between at the bottom of reinforced concrete cast-in-situ plate top reinforcement and the cast-in-place plate, the reinforcing bar split heads is set then.
2, require site preparation that several fonts, vertical bar shaped reinforcing bar split heads are set according to reinforced concrete cast-in-situ plate thickness and top reinforcement protective layer thickness.
3, use to replace the reinforcing bar split heads for the relatively thinner reinforced concrete cast-in-situ plate site preparation concrete pier of thickness.
4, use the typing Steel bar rack and the split heads of manufacturer production on the market.
Two, the control of reinforced concrete cast-in-situ plate thickness
1, on the wall of cast-in-place edges of boards, the post master muscle or other exceed on the object of cast-in-place plate plate face absolute altitude and copied cast-in-place plate plate face control absolute altitude.
2, the constructor receives at ordinary times according to the absolute altitude backguy construction levelling control thickness of slab of copying.
The reinforced concrete works quality of above way after to its moulding still do not reach ideal designs and job specfication requirement.Be mainly reflected in two aspect problems: one, floor top reinforcement protective layer thickness are uneven less than normal or bigger than normal.Two, the reinforced concrete cast-in-situ plate thickness is thick partially.Entangle its reason and be each work post cross-operation on its work plane in the construction, the constructor walks frequently, stops over nowhere, and cast-in-place plate top reinforcement is trampled unavoidably in a large number; Particularly water in the process of smashing at concrete cast-in-place slab; the position is all very correct during reinforcing bar binding often; but once situation changes when smashing to watering; when especially on relatively thinner reinforced concrete cast-in-situ plate, constructing; be not that the people steps on be exactly above Work tool is pressed in; the result who causes thus is the reinforcing bar split heads or the riding of bearing bar or topples over, the negative reinforcement flexural deformation of concrete upper strata, and the thickness of topping also just can not get guaranteeing.Present most engineering adopts pumping of concrete; pump line end conduit is wayward during construction; during operation; conduit is owing to the influence of inertia such as being subjected to that concrete impact and pump line move; direction is difficult to hold; cause constructor's astasia and trample the upper strata negative reinforcement making its displacement, it is bigger than normal to cause thickness of protection tier to differ.Secondly its plate face absolute altitude control is inaccurate during concrete construction, is to guarantee the acceptance on examination code requirement, can only cause the reinforced concrete cast-in-situ plate thickness generally super thick thus by guaranteeing to allow the overgauge construction, causes that thickness of protection tier is bigger than normal also to cause the wasting of resources.Between the levels reinforcing bar that double-layer double-directions such as the Reinforced Concrete sole plate in highrise building or some large equipment bases and high thick reinforced concrete cast-in-situ plate are provided with.Steel bar rack adopts the Steel bar rack of reinforcing bar welding production more and uses shape steel bracket mainly to adopt angle steel and channel-section steel to be welded to form.Support the weight of top reinforcement, with the absolute altitude of control reinforcing bar and whole working load of top operating platform.Consequently: a, whichever way are disposable input and cause the wasting of resources; B, building load increase; The anti-permeability performance of c, reduction steel concrete.How onboard the cast-in-place plate local cracks of invar reinforced concrete portion; prolong negative reinforcement topping longitudinal cracking; water is penetrated on negative reinforcement and the reinforcing bar split heads supporting leg along this crack; prolong reinforcing bar split heads supporting leg and be penetrated at the bottom of the plate, the reinforcing bar split heads supporting leg of this moment just played the reinforced concrete cast-in-situ plate up and down between the effect of water conservancy diversion bridge and cause plate at the bottom of rust spot.
