Description
Technical Field
The utility model relates to a steel construction quality control field, more specifically relates to a bottom of beam reinforcing bar protective layer thickness control device.
Background
In the building engineering, the construction quality of a reinforced concrete structure is of great importance, and how to control the thickness of a reinforced protective layer is always an important technology in the aspect of quality control in the building engineering. Common protective steel bar layer thickness control system has all kinds of cushion, the stirrup, the stay etc, receive structural reinforcement skeleton machining precision and protective layer thickness controlling means installation accuracy and installation quality's influence, cushion or controlling means uneven circumstances of atress often can appear, lead to the cushion by crushing or pressure deformation, finally lead to local protective layer thickness to obtain not effective control, especially to the reinforced concrete roof beam of high large cross-section, because the framework of steel reinforcement dead weight is great, in case the cushion atress is uneven appears, lead to the cushion individually because of concentrating the atress and being crushed or pressure deformation very easily, and hardly take remedial measure after the reinforcing bar installation is accomplished, lead to unable assurance beam bottom reinforcing bar protective layer thickness well. Therefore, how to effectively control the thickness of the steel bar protection layer at the bottom of the beam is a technical problem to be solved urgently in the prior art.
SUMMERY OF THE UTILITY MODEL
To the problem that exists among the above-mentioned prior art, the utility model provides a can guarantee beam bottom protective layer thickness's beam bottom protective layer thickness controlling means effectively.
In order to achieve the above purpose, the present invention is implemented by the following technical solutions.
The utility model provides a beam bottom reinforcing bar protective layer thickness control device, includes by the roof beam owner muscle with be used for the ligature the skeleton that the roof beam stirrup of roof beam owner muscle constitutes, the lower terminal surface of skeleton is provided with the packing ring, the packing ring the roof beam owner muscle with the crosspoint of roof beam stirrup is provided with the ligature silk the lower terminal surface of packing ring is followed the peripheral interval of packing ring is provided with the cushion.
The gasket and the cushion block are bound into a whole through binding wires.
The shape of the gasket is one of a rectangle, a triangle, a diamond, a hexagon or a circle.
The plane size of the gasket is adaptive to the width of the cross section of the beam, and the diameter of the gasket is adaptive to the thickness of the steel bar protection layer at the bottom of the beam and the thickness of the cushion block.
The positions and the number of the cushion blocks are adapted to the stress performance of the cushion blocks and the weight of the beam main reinforcement.
The spacer is made of one of finished mortar, plastic or concrete.
Compared with the prior art, the utility model beneficial effect be: according to the dead weight of the beam, the section size of the beam and the thickness requirement of the reinforcing steel bar protection layer at the bottom of the beam, the gaskets and the cushion blocks are mutually bound and matched for use, so that each cushion block is uniformly stressed, the thickness of the reinforcing steel bar protection layer is effectively controlled, the binding process of the cushion blocks and the gaskets can be completed before construction, and the construction efficiency can be improved.

Detailed Description
The present invention will be further explained with reference to the following examples.
The thickness control device for the beam bottom steel bar protection layer shown in fig. 1-2 comprises a framework consisting of a beam main bar 3 and a beam stirrup 4 used for binding the beam main bar 3, wherein a gasket 1 is arranged on the lower end face of the framework, binding wires are arranged at the intersection of the gasket 1, the beam main bar 3 and the beam stirrup 4, the gasket 1 is rectangular, the plane size of the gasket 1 is adaptive to the width of the beam section, the diameter of the gasket 1 is adaptive to the thickness of the beam bottom steel bar protection layer and the thickness of a cushion block, and in order to save materials and reduce waste, the gasket 1 is made of secondarily utilized steel bars. The lower end face of the gasket 1 is provided with cushion blocks 2 at intervals along the periphery of the gasket 1, the cushion blocks 2 are flatly placed below the gasket 1, the conventional embedded binding with a steel bar framework is different from the conventional embedded binding with the steel bar framework, the gasket 1 and the cushion blocks 2 are bound into a whole through binding wires, the positions and the number of the cushion blocks 2 on each gasket 1 are adapted to the stress performance of the cushion blocks 2 and the weight of a beam main rib 3, and the cushion blocks 2 are made of finished mortar.
In other embodiments of the present invention, the shape of the gasket 1 is triangular, rhombic, hexagonal or circular.
In other embodiments of the present invention, the spacer 2 is made of plastic or concrete, respectively.
Before construction, the shape, the plane size and the diameter of the gasket 1, the specification of the cushion block, the binding quantity and the binding position are selected according to the requirements of the self weight and the section size of the beam and the thickness of the reinforcing steel bar protection layer at the bottom of the beam. Use the ligature silk in advance to ligature cushion 2 to packing ring 1 in the material processing factory, then on the whole that will make up the packing ring 1 and cushion 2 is placed the roof beam die block 5 at the job site, in ligature roof beam owner muscle 3 and roof beam stirrup 4, with packing ring 1 ligature on the crosspoint of roof beam owner muscle 3 and roof beam stirrup 4, packing ring 1 can be certain angle slope and place, the side or the angle of packing ring 1 support the lateral wall of roof beam side template 6, thereby make packing ring 1 can be ligatured with the crosspoint of more roof beam owner muscle 3 and roof beam stirrup 4, thereby make the ligature more firm, help controlling the thickness of protective layer of reinforcing bar better.
The above description is only the preferred embodiment of the present invention, but the present invention is not limited to the above-mentioned specific embodiments, and for those skilled in the art, a plurality of modifications and improvements can be made without departing from the inventive concept of the present invention, and these modifications and improvements all belong to the protection scope of the present invention.
