Technical field
The utility model relates to construction auxiliary device technical fields, disclose a kind of beam reinforced steel bar protective layer control dress
It sets.
Background technique
In architectural engineering, important evidence of the thickness of protection tier as acceptance of engineering quality, quality requirement is high, therefore
In the construction of architectural engineering cast-in-situ floor, to ensure the construction quality, main body examination is passed through, when construction must effectively control reinforcing bar
The position of frame guarantees to form certain thickness concrete cover around reinforcing bar, so that reliably gluing between reinforcing bar and concrete
It ties, prevent steel bar corrosion.But the control of thickness of protection tier belongs to the common quality defect of concrete structure, control is difficult.
Currently, in engineering for guarantee thickness of protection tier, generally use mortar pad, plastic cushion, steel bar horse-shaped bench and
The measures such as Steel bar rack.But after mortar pad is vibrated, it is easy displacement；Plastic cushion intensity is insufficient, thermal expansion coefficient with
Concrete difference is big, Nian Jie poor between plastics and rear casting concrete, easily causes and causes corrosive medium intrusion, leads to plastics ring
Interior reinforcing bar corrodes.Though steel bar horse-shaped bench and Steel bar rack control effect are preferable, steel using amount is big, and bending machining at the scene
Difficulty, while being easy to corrode at soffit supporting point, influence later period decoration construction.Especially beam reinforced steel bar is protected
Layer, due to working face, operating personnel is more, and the various tired elements of influence are more, if according to traditional cover to reinforcement control measure, it is difficult
To meet higher and higher construction reference, cause great trouble for engineering construction quality and main body examination.
Utility model content
In order to overcome many shortcomings and deficiencies present in above-mentioned background technique, the utility model provides a kind of beam reinforced steel bar
Protective layer control device, can be effectively controlled the thickness of cover to reinforcement, reduce common quality defect, improve construction quality, high reliablity,
It can be mass simultaneously, cost is relatively low, and it is easy for installation, it is time saving and energy saving.
The technical scheme adopted by the utility model is a kind of beam reinforced steel bar protective layer control device, including ontology (1),
Ontology (1) is supported by pedestal (2), and the ontology (1) is groove structure, and several put for load is arranged on ontology (1) and arranges on beam slab
The U-type groove (3) of muscle (4), pedestal (2) setting are adjustable structure at ontology (1) both ends.
Further, ontology (1) both ends open up threaded hole, and pedestal (2) is connect by threaded hole with ontology (1).
Further, the pedestal (2) is placed on template (5), and pedestal (2) includes bottom cushion block (21) and screw rod
(22), bottom cushion block (21) and screw rod (22) are welded to connect.
Further, the bottom cushion block (21) is rectangular or round.
Further, the width of the U-type groove (3) is slightly larger than the diameter of upper row's muscle (4).
Further, it is cover to reinforcement design value that U-type groove (3) bottom, which is higher by the distance of template (5),.
Further, the screw thread pole length of the pedestal (2)≤ontology (1) height.
The utility model can be fabricated to different sizes according to the diameter of reinforcing bar.Work progress are as follows: when reinforcing bar is bound in beam
After the completion of arrangement, using template (5) as supporting point, upward by the ontology (1) of the present apparatus, pedestal (2) downward, the row's of being placed on muscle
(4) lower part is placed in reinforcing bar in U-type groove (3), and then according to cover to reinforcement design value, the threaded rod of adjustment base (2) is high
The distance of ontology (1) bottom out, to achieve the purpose that adjust thickness of protection tier.In this way, reinforcing bar in beam can be maked somebody a mere figurehead.This
When, distance of the bottom reinforcement bars apart from beam bottom portion is the defined thickness of protection tier that beam bottom portion reserves.It can carry out later
Concrete pours.
Compared with prior art, beneficial caused by a kind of beam reinforced steel bar protective layer control device disclosed by the utility model
Effect is:
1) the utility model is structurally reasonable simple, manufactures and is easy, easy to use and flexible, when operation, device is direct
It is placed in template, meanwhile, after beam pours, the present apparatus is completely covered, and any influence will not be generated to construction, and energy is interfered in anti-construction
Power is strong.
2) U-type groove being arranged, can be steadily fixed by upper row's muscle, and bar spacing can be effectively controlled.
3) the utility model effectively controls concrete cover to reinforcement thickness by adjustment base, according to different deck-moldings
With the protective layer thickness adjustment base of needs.

Specific embodiment
The utility model is described in further detail below by drawings and examples, but the protection model of the utility model
It encloses and is not limited to the content.
As shown in Figure 1 to Figure 3, in certain engineering construction project, it is desirable that thickness of protection tier is not less than 50mm, adopts
A kind of beam reinforced steel bar protective layer control device, ontology 1 are the groove structure being welded using square steel, square steel wall thickness 2mm,
Using being welded with a thickness of the plinth cushion block 21 of 5mm with screw rod 22, pedestal 2 and ontology 1 are connected pedestal 2 by threaded hole
It connects, the both ends of ontology 1 is set.According to number of steel bars, the U-type groove 3 of respective numbers is opened up on ontology 1, the width of U-type groove 3 omits
Greater than the diameter of upper row's muscle 4.
Due to requiring thickness of protection tier not less than 50mm, it is therefore desirable to 3 bottom of U-type groove be higher by the distance of template 5 >=
50mm.In the present embodiment, the square steel wall thickness of ontology 1 is 2mm, the high 30mm of bottom plate of the distance from bottom ontology 1 of U-type groove 3, and pedestal
2 bottom cushion block 21 is with a thickness of 5mm, at this time, it is only necessary to and adjustment screw 22 guarantees effective support distances >=13cm of screw rod 22,
Thickness of protection tier requirement can be met.
In order to guarantee to pour the surface that rear screw rod 22 does not leak out table beam, it is desirable that screw thread pole length≤ontology 1 height of pedestal 2
Degree.
After the completion of reinforcing bar binding arrangement in beam, using template 5 as supporting point, the ontology 1 of the present apparatus in upper, pedestal 2
Under, it is placed on the lower part of upper row's muscle 4 of beam, according to design value, effective support distances of adjustment screw 22, thus by steel in beam
Ledges is empty, reserves defined thickness of protection tier in beam bottom portion with this.Then pouring for concrete is carried out.After the completion of pouring
Effect picture it is as shown in Figure 4.
