Description
Technical field
The present invention relates to building field, is a kind of floor bar topping dual control precast concrete cushion block and mounting method thereof.
Background technology
At engineering construction field; during floor slab structure construction; strict control floor plan thickness and thickness of protection tier are very important on the safety of structure, durability impact, and a kind of construction technology therefore must be had effectively to control protective layer thickness and the floor plan thickness of floor two placing of reinforcement.Traditional construction generally adopts knockdown method to control protective layer thickness and the slab thickness of reinforcing bar, there is quality control difficulty large, the common faults such as inconvenient operation.Such as, on floor, placing of reinforcement adopts the split heads of the shape such as " A ", " H ", " I " font to support gluten, lower placing of reinforcement adopts plastic cushion, cement blockages etc. are as topping cushion block, slab thickness then adopts " instrument controlling method ", methods such as " reinforcing bar insertions " controls, and these methods exist following shortcoming: 1. traditional split heads specification is many and assorted, irregularities during actual installation; 2. work consuming consuming time is processed in field fabrication; 3. stable material quality is poor, stressedly easily crackedly to cave in afterwards; 4. manual manufacture cushion block real size deviation is large; 5. construction cost is high, and green construction is not up to standard; 6. construction quality is difficult to control; 7. combination operation management difficulty is large.For this reason, need to be improved existing cushion block of concrete bar protective layer.
Summary of the invention
For overcoming above-mentioned deficiency; the object of the invention is to provide a kind of floor bar topping dual control precast concrete cushion block and mounting method thereof to this area, make it solve existing like product function singleness, comparatively loaded down with trivial details, that construction quality is difficult to guarantee technical problem is installed.Its objective is and to be achieved through the following technical solutions.
A kind of floor bar topping dual control precast concrete cushion block, this topping cushion block comprises the upper support notch for supporting placing of reinforcement on floor, and for supporting the lower support notch of underfloor placing of reinforcement.Its structural feature is that described topping cushion block comprises feet and a pair lower support pin on a pair, described upper support notch is provided with between upper feet, described lower support notch is provided with between lower support pin, wherein two upper feets are a short length, long upper feet top is slab thickness to the vertical height between lower support foot bottom, vertical height between long upper feet top to short upper feet top is upper placing of reinforcement protective layer thickness, vertical height in lower support foot bottom to described lower support notch between lower placing of reinforcement bottom side is lower placing of reinforcement protective layer thickness.This design compared with prior art; the restriction to slab thickness, upper placing of reinforcement protective layer thickness, lower placing of reinforcement protective layer thickness can be realized simultaneously; floor and floor bar topping without the need to can realize respective thickness by additional support are built; construction more for convenience; labour intensity and cost lower; efficiency of construction is high, and quality is comparatively reliable.
One shorter in two described upper feets upper feet end is plane, and on another, the end of feet is protruding cambered surface; The end of two described lower support pin is plane.By this design, improve the stability of strutting system of topping cushion block on the one hand, improve the firmness that topping cushion block is connected with cast-in-situ floor concrete on the other hand.
Waist between the upper feet of described topping cushion block, lower support pin is provided with the waterproof ring of concave or convex.Designed by this waterproof ring, effectively prevent floor by topping cushion block seepage.
Lower support notch inner bottom part between two described lower support pin is embedded with for supporting in lower support notch lower placing of reinforcement.By being coordinated with topping cushion block by lower cushion block, globality is better, uses more for convenience, supports comparatively stable.
The mounting method of this floor bar topping dual control precast concrete cushion block is: first determine slab thickness, and floor interior upper placing of reinforcement protective layer thickness, lower placing of reinforcement protective layer thickness, the described topping cushion block of correspondingly-sized is then chosen according to this slab thickness and protective layer thickness; During installation; first floor bar is carried out the fixing formation of colligation upper placing of reinforcement, lower placing of reinforcement; then by placing of reinforcement under lower cushion block supporting and location; again the lower support notch of described topping cushion block and lower placing of reinforcement contraposition are placed; upper placing of reinforcement is positioned in the upper support notch of described topping cushion block; complete the location of placing of reinforcement on floor, lower placing of reinforcement; finally carry out concreting according to the height of described topping cushion block; vibrated by machinery, modify leveling, plastic film covering maintenance, namely complete concrete floor slab placement construction.
Structure of the present invention is comparatively simple, and more for convenience, installation strength is low, and operating efficiency is high in construction, and the reinforcement cover pad being suitable for all kinds of concrete floor slab placement construction of building field uses soon, or the improvement of similar construction method.
