Abstract
The utility model relates to a reinforced negative reinforcement cover controller which comprises a rack body; a nut, a screw rod, a pull rod and a movable pull rod are installed on the rack body, a control board and the movable pull rod are respectively connected at the lower end of the screw rod, and a mesh reinforcement is arranged below the control board; and the reinforced negative reinforcement cover controller adopts the method for controlling the thickness of a reinforced concrete slab, i.e., binding the reinforced steel bars, mounting the controller, adjusting the screw rod on the controller to the design slab thickness, fixing the negative reinforcement, pouring concrete, dismantling a suspension bracket, taking out the controller before the initial setting of concrete, and leveling the concrete slab. The problem that the negative reinforcement is trampled is well solved, and the common quality problem that the thickness of the concrete slab and the reinforcement cover are not easily controlled is also well solved; the qualification rate of thickness of the concrete slab as well as the qualification rate of the negative reinforcement cover is up to 95 percent; compared with the traditional construction method, the construction difficulty is reduced, and the product quality is improved; and the blower station for the1580 Wuhan iron and steel plant, the electrical room, the carbon steel cold-rolling electrical room for Jisco and the main 120tRH furnace building floor all adopt the reinforced negative reinforcement cover controller for construction, the product quality is good, and the economic benefit is obvious.
Description
Technical field
The utility model relates to a kind of controller of controlling the thick and negative tendon protective layer of cast-in-situ reinforced concrete slab.
Background technology
In the construction work practice; the entity detection of concrete slab thickness and negative tendon protective layer thickness; the qualification rate of finding concrete slab thickness and negative tendon protective layer thickness only is about 45%; these common faults are in a large amount of existence; it is unsturdy to engineering quality control work to expose enterprise in charge of construction; the quality certification system imperfection, weakening of quality controlling consciousness.In order effectively to administer the concrete quality common fault, prevent that the negative muscle of cast in place concrete plate is excessive to bottom offset, cause concrete slab structure hidden danger; by practice, worker's method of suspension method control thickness of protection tier has not only reached the purpose of controlling effect stability; and the cost of material is low, and manually-operated is easy.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aims to provide a kind of reinforcing bar negative tendon protective layer controller that a kind of cost is low, simple to operate, efficiency of construction is high, safe and reliable.
The implementation of the utility model purpose is; reinforcing bar negative tendon protective layer controller; have upper and lower framework and between the perpendicular support body that is configured to of connection; the upper frame upper end is welded with nut; screw rod passes nut; the screw rod lower end is connected with control panel, active pull rod, and the two ends of active pull rod are connected with perpendicular frame by connector, and the control panel below is connected with steel mesh reinforcement.
The utility model is compared with the existing fixed frame, and advantage is repeatedly to use.The utility model is suitable for the thickness range of 50mm～300mm., can increase the hard packing piece and handle, and needn't make reinforcing bar negative tendon protective layer controller in 30mm the time as thickness of slab.
The utility model has solved negative muscle well and has been stepped across, the uppity common quality defect of concrete thickness of slab and reinforcement cover.Conventional construction method has reduced cost and operation easier relatively, has improved efficiency of construction and workmanship, and is safe and reliable.Adopt the utility model, concrete thickness of slab and negative tendon protective layer qualification rate reach more than 95%.The utility model construction is all adopted at Wuhan Iron and Steel Plant 1580 blast fan stations, electric panel room, the cold rolling electric panel room of wine steel carbon steel, 120tRH stove main building floor, good product quality, and economic benefit is obvious.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the state diagram with the utility model control steel concrete thickness of slab.
The specific embodiment
The utility model is described in detail in detail with reference to the accompanying drawings.
With reference to Fig. 1,2, controller of the present utility model have upper and lower framework and between the support body that constitutes of the perpendicular frame 4 of connection, upper frame 1 upper end is welded with nut 3, screw rod 2 passes nut, the screw rod lower end is connected with control panel 7, active pull rod 5, the two ends of active pull rod 5 are connected with perpendicular frame 4 by connector 6, and control panel 7 belows are connected with steel mesh reinforcement 8.
The high 350mm of support body, screw rod 2 is not less than 150mm in the length of upper frame more than 1, to guarantee the stability of controller.
The crossbearer of upper frame 1 is the square tube of two 50mm * 50mm * 2mm, two tube pitch are about 800mm, two ends connects with the square tube of 50mm * 50mm * 2mm, pull bar 9 is arranged in the middle of the crossbearer of upper frame 1, clearance between tiebars 800mm, pull bar 9 adopts the square tube of 40mm * 40mm * 2mm or the reinforcing bar of diameter＞12mm.
It is the steel pipe of 40mm, thick 2mm that active pull rod 5 adopts 40mm * 40mm * 2mm square tube or diameter, and the below of active pull rod is welded with spike 10.It is the round steel of 14～16mm that spike adopts band iron or the diameter of 15mm, with control topping height.
The utility model is taking into full account satisfied repeatedly use, under the requirement that different thicknesss of slab constructions can both be used, considers simultaneously to satisfy the monolithic stability sexual demand, and has enough rigidity, reduces difficulty of construction, minimizing labour intensity.
Job step with the utility model control steel concrete thickness of slab is as follows:
1) install template, the cast-in-place plate face of colligation reinforcing bar,
2) reinforcing bar negative tendon protective layer controller is installed, adjusting screw(rod) makes the steel mesh reinforcement bottom surface to steel concrete thickness of slab place,
3) hang negative muscle to the controller end opening, will bear the muscle colligation on the control panel of active pull rod lower end with 22# colligation silk,
4) fluid concrete, the colligation silk that comes loose before concrete initial set takes out controller,
5) hole that stays of floating spike 10,
[0021] 6) removes concrete in the control, and local deformation place is revised, so that use next time.
