Description
Technical field
This utility model is related to the realm of building construction and in particular to beam bottom cover to reinforcement is constructed.
Background technology
In architectural engineering, cover to reinforcement size Control to reinforced concrete member safety, durability important not
Say and explain.Protective layer is too small or unprotect layer, and concrete starts shedding off in time, the easy corrosion of reinforcing bar, and intensity decreases, with coagulation
Soil is peeled off, and member stress system is destroyed.Protective layer is excessive, cannot be played maximum effect by tensile region reinforcing bar and use, concrete component
Cracking, destruction, same harm is big.
In construction, how effective control reinforcing bar protective layer becomes emphasis and the difficult point of work, especially for beam section
The Vierendeel girder that size is larger, bar diameter is thicker.Beam bottom protective layer controls how to control using in beam bottom laying cushion block at this stage
Thickness of protection tier, but in practical operation, easily problems with construction traditional method：
1. cushion block is difficult to select：Traditional mortar pad low intensity, is easily broken, comes off when big weight indulges muscle compressing,
Lose protected effect；If changing Gypsum Fibrosum cushion block into, after form removal, Gypsum Fibrosum light faces outwardly, and affects perception, to the bottom decorations of later stage beam not
Profit.
2. operation easier is big, and quality is difficult to ensure card.Beam bottom muscle, after falling in mould, puts into cushion block material in beam, using people
Work steel pipe levers up beam muscle, and other people stir cushion block to beam stirrup bottom at cooperation.This mode reinforcing bar is subject to disturbance larger after colligation, right
Tie with reinforcing bar, Forming Quality affect greatly.Waste a large amount of manpowers simultaneously and delay the engineering time.
Content of the invention
For problem above, the utility model proposes a kind of device for controlling beam bottom cover to reinforcement effect, make
With the welding of waste material reinforcing bar simple combination, form beam and indulge muscle stirrup support system, by the side erecting beam upper longitudinal bar, positioning
Formula, controls beam bottom to indulge muscle, the position of stirrup, thus facilitating beam bottom cover to reinforcement to control construction, and then guarantees to facilitate beam bottom steel
Tendon protective layer meets specification and drawing requirement.
For achieving the above object, the technical solution adopted in the utility model is：Proposing one kind can effective control beam bottom reinforcing bar
The device of protective layer effect, indulges muscle and girder stirrup including girder, and girder is indulged muscle and included back muscle and beam bottom muscle, back muscle and beam
Bottom muscle is fixed by girder stirrup, is provided with the stirrup support meanss across girder, stirrup support meanss are by horizontal stroke below back muscle
To spacer bar and supported rod erecting composition, two supported rod erectings are individually fixed in the two ends of cross-brace reinforcing bar, supported rod erecting position
On the slab form of girder both sides, the bottom of supported rod erecting carries stablizes bottom rod, stablizes setting between bottom rod and slab form
There is spacer bar protection cushion block, between the girder stirrup below the muscle of beam bottom and beam bottom mother plate, be provided with beam bottom tendon protective layer cushion block.
The reinforcing bar that muscle is same size indulged by described cross-brace reinforcing bar and girder.
Described two supported rod erectings are symmetrically distributed in the both sides of girder, and every supported rod erecting and the beam sideline with its homonymy
The distance between be 15-20cm.
The drawbacks of this utility model can be effectively improved traditional beam bottom protective layer construction method, has the advantages that：（1）
Protective layer controls proper：Back ledges is risen by stirrup support meanss, unjointed beam muscles and bones frame fix in position, and beam bottom only need to locally be aided with
Cushion block, cushion block pressure-bearing is little, it is to avoid coming off or pulverize thus affecting to protect because of cushion block generation under pressure in traditional method
The drawbacks of layer effect, beam bottom tendon protective layer can get effective control；（2）Improve construction quality：By arranging below back muscle
The upper longitudinal bar of girder is erected and is positioned by stirrup support meanss, controls the position that muscle and stirrup are indulged in beam bottom, thus conveniently entering
The protective layer of cross girders bottom reinforcing bar controls construction, has abandoned to need in traditional construction manually to prize beam bottom muscle and could place applying of cushion block
Work method, it is to avoid the protective layer of traditional beam bottom reinforcing bar controls the impact to framework of steel reinforcement and Forming Quality for the construction；（3）Processing is fast
Prompt：It is existing that stirrup support meanss adopt waste material reinforcing bar to pass through simple welding combination；（4）Laying is convenient：Stirrup support meanss are being tied up
After pricking beam muscle, place before the reinforcing bar of whereabouts, one to two workmans get final product easy manipulation；（5）It is easy to check：Management personnel and applying
Workman person all clearly can check difficulty action accomplishment, is easy to check；（6）Green construction：Reduce traditional cement mortar bedding block, using existing
Field useless steel bar end processing, frugally material, waste wood utilizes, and meets green construction requirement.
This utility model is conducive to saving manpower, improves efficiency of construction and construction quality, is worth promoting in engineering practice
Application.
