Description
Technical field
The present invention relates to cushion block of concrete bar protective layer technical field, more particularly to a kind of cushion block of concrete bar protective layer fixed structure and
Method.
Background technology
Cushion block of concrete bar protective layer is in brick mix structure, is placed under beam, is to solve partial pressing to expand bearing area
Shi Changyong method.Concrete cover to reinforcement thickness relationship is to performances such as the bearing capacity of structure, durability, fire prevention.
At present, publication number：CN102912980B patent, disclose a kind of cushion block of concrete bar protective layer fixing means, its side
Method mainly first designs a cushion block of concrete bar protective layer for carrying rectangular through holes, and rectangular through holes are referred to as steel tank, steel band concatenation
Upper multiple cushion blocks, steel tank pass through by flat steel band, and it is using general to be limited for cushion block in the free degree of steel band length direction
Steel band bending carries out spacing, and steel band is advantageous to limit rotation of the cushion block on steel band, realizes the fixation to cushion block, and by cushion block
String is fixed on framework of steel reinforcement by improving bud grafting.
Said structure solve technical problem be：How to solve the problems, such as that cushion block rotates around reinforcing bar, specifically, constructing
Cushion block on the bottom plate of the scattered fixation in scene, easily turns on one's side, the cushion block of fixed side easily rotates around reinforcing bar.
Technical scheme in above-mentioned patent document can solve above-mentioned technical problem, but be not to solve above-mentioned technology to ask
The preferred scheme of topic.Using above-mentioned technical proposal, found in implementation process：An above-mentioned steel tank is designed on cushion block, cushion block
Structure in the case of no steel band its structural strength it is relatively low, steel tank breakage in transportation be present；Using steel band,
Then cost is excessive on steel tank materials, and needs to be bent steel band to limit cushion block movement, it is necessary to which other instruments are grasped
Make to cause steel band to bend, it is inefficient.
The content of the invention
In view of the deficienciess of the prior art, it is an object of the invention to provide a kind of cushion block of concrete bar protective layer fixing means,
Advantage with simple, the effective control cost of constructing operation.
The present invention above-mentioned technical purpose technical scheme is that：A kind of cushion block of concrete bar protective layer is consolidated
Determine method, comprise the following steps：
Step 1, if preparing stem structure identical cushion block monomer, each cushion block monomer includes upper wall surface, lower wall surface and four side walls
Face, four side walls are respectively side wall one, side wall two, side wall three and side wall four, the side wall of the cushion block monomer
Through there is first through hole between face one and side wall three, running through between the side wall two and four of the cushion block monomer has second to lead to
Hole, the first through hole and the second through hole are mutually perpendicular to and are staggeredly located；
Step 2, some cushion block monomers formation cushion block bars are covered by first through hole on steel bar；
Some cushion block bars are made in step 3, repeat step two；
Step 3, some identical cushion block bars are placed in parallel, and another steel bar is passed through by the second through hole and is in steel bar same position
On cushion block, some steel bars in grid be distributed and cushion block be in grid intervening portion；
Cushion block face is formed by step 3.
By above-mentioned setting, first through hole and the second through hole are set on cushion block, are easy to the installation of steel bar, and by above-mentioned
Step, cushion block face is formed, cushion block monomer is spacing firmly by the steel bar of the steel bar of transverse direction and longitudinal direction, and cushion block can not move on three dimensions
Dynamic, steel bar interlocks in grid, and cushion block position is in intervening portion, and cushion block is positioned by steel bar, and mounting means is simple, fixation,
Materials are saved, and cushion block is wide, and structural support intensity is higher.
Can be preferably as concrete scheme of the invention：First determine the cushion block number m and width of cushion block face length direction
