Abstract
The invention provides a concrete floor slab thickness control device and a construction method thereof, and belongs to the technical field of building construction. The concrete floor slab thickness control device is mainly composed of the following structures that a phi 10mm reinforcing steel bar (2) is welded on a 100*50*3mm steel plate base (1), wherein the length of the reinforcing steel bar (2) is 6mm smaller than the thickness of a floor slab; a 50*50*3mm horizontal control steel plate (3) is welded at the other end of the reinforcing steel bar; and phi 3 iron nails (4) are arranged. The construction method comprises the step that after cast-in-situ floor slab reinforcing steel bars are bound, the phi 3 iron nails (4) are used for nailing and fixing the concrete floor slab thickness control device which is formed by welding the 100*50*3mm steel plate base (1), the phi 10mm reinforcing steel bar (2) and the 50*50*3mm horizontal control steel plate (3) with a formwork. When floor slab concrete is poured and tamped, the height of the horizontal control steel plate (3) is the thickness of the floor slab; the concrete higher than the horizontal control steel plate (3) is scraped through an aluminium alloy floating rule; and after a cast-in-situ floor slab bottom die is dismounted, the exposed steel plate base (1) is coated with neat cement grout. The concrete floor slab thickness control device has the characteristics of being simple in structure, convenient to operate and high in precision of control over the thickness of the floor slab.
Description
Technical field
The present invention relates to building industry technical field of construction, refer in particular to a kind of for concrete floorslab thickness control device and construction method.
Background technology
Along with the gradually stepping up of increasingly mature and whole people's quality mind of China building construction development, construction quality has become the focus of social concerns.In construction process, most large-scale developers have introduced third party and have surveyed actual quantities unit and be estimated work progress, assessment result has become the voucher that engineering price pays, wherein slab thickness controls is central priority control project, and slab thickness is undesirable will directly influence the safe handling requirement of structure.In order to improve slab thickness control accuracy in construction, create the product of higher quality, by constantly exploring accumulation, define a kind of for concrete floorslab thickness control device and construction method.
Summary of the invention
The technical problem to be solved in the present invention is: generally slab thickness controls is to carry out floor elevation control by the absolute altitude control point on vertical structure reinforcing bar, thus reach to control slab thickness, because the method controls thickness of slab easily causes bigger error, and there is no control point in the middle of big room, it is difficult to control accurate to Large Floor thickness.A kind of device higher to concrete floorslab thickness control accuracy and construction method is provided for this.
The technical solution adopted for the present invention to solve the technical problems is: a kind of concrete floorslab thickness control device and construction method, it is characterised in that: determine slab thickness kind according to construction drawing, and make the floorslab thickness control device of dimension.After cast-in-situ floor reinforcing bar binding completes, the floorslab thickness control device using Φ 3 iron nail (4) 100 × 50 × 3mm steel plate base (1), Φ 10mm reinforcing bar (2), 50 × 50 × 3mm level control steel plate (3) to be welded into is firmly fixed with Template nail.Watering when smashing floorslab concrete, level controls the height of steel plate (3) and is slab thickness, with aluminium alloy floating rule, the concrete controlling steel plate (3) higher than level is struck off, and exposed steel plate base (1) is brushed neat slurry after removing by cast-in-situ floor bed die.
Specifically comprising the following steps that of a kind of concrete floorslab thickness control device of the present invention and construction method
1, it is familiar with construction drawing and lists slab thickness kind, Φ 10mm reinforcing bar (2) of corresponding length is made according to slab thickness, the circular hole opening two diameter 4mm on 100 × 50 × 3mm steel plate base (1) passes for iron nail, then being welded on 100 × 50 × 3mm steel plate base (1) by Φ 10mm reinforcing bar (2) of corresponding length, reinforcing bar other end welding 50 × 50 × 3mm thickness level controls steel plate (3).
2, after cast-in-situ floor reinforcing bar binding completes, the number of cast-in-situ floor thickness control device, cubicle (12m are selected according to room area size22 cast-in-situ floor thickness control devices can be set below), position is set respectively local away from minor face midpoint, room 500mm；Middle big room (12m2More than and) 5 cast-in-situ floor thickness control devices are preferably set, position is set respectively away from four, room arm of angle 500mm tetra-and geometric center one.Then the floorslab thickness control device using Φ 3 iron nail (4) 100 × 50 × 3mm steel plate base (1), Φ 10mm reinforcing bar (2) 50 × 50 × 3mm level control steel plate (3) to be welded into is firmly fixed with Template nail.
3, water when smashing floorslab concrete, find the position of floorslab thickness control device, level controls the height of steel plate (3) and is slab thickness, observe this position concrete thickness, if concrete surface is less than level control board (3) absolute altitude, concrete need to be added to horizontal control surface plate (3), then with aluminium alloy floating rule, the concrete controlling steel facing (3) higher than level is struck off.
4, after floorslab concrete reaches design strength form removal, remove concrete chip and the iron nail head at floorslab thickness control device base steel plate (1) place, then carry out exposed base steel plate (1) brushing neat slurry.
Compared with prior art the present invention has simple structure, easy to operate, the advantage high to concrete floorslab thickness control accuracy.
