Abstract
The utility model relates to a concrete protective layer cushion block for reinforced steel bar, it is pegged graft the cooperation by cushion units of two semicircle pies and forms, the diameter center shaping of every cushion unit has a semicircular reinforcing bar holding hole, the both sides in reinforcing bar holding hole respectively the shaping have the boss and with boss corresponding match's concave station, every cushion unit is equipped with at least one ligature hole. The utility model discloses a grafting fits forms cake shape cushion, has following advantage: 1. Simple structure, convenient operation, simple, 2. Guarantee thickness of a concrete protection layer's uniformity, 3. The installation is firm, is difficult to come off after the grafting is good, prevents after reinforcing bar and the cushion ligature that the cushion from shifting.
Description
Technical field
The utility model relates to a kind of concrete cover cushion block.
Background technology
In building with bridge engineering, the main member of load-bearing is built with steel concrete, and steel concrete has given full play to the advantage that concrete crushing strength is higher and Steel Bar Tensile Strength is higher, effectively improves the supporting capacity of concrete structure.Steel bar spacer is the important component part ensureing that reinforcement placement validity is indispensable; both around reinforcing bar, certain thickness concrete cover was formed; effectively control again the position of cage of reinforcement, ensure that reliable bond between reinforcing bar and concrete and prevent reinforcing bar by corrosion.
In current engineering, the normal steel bar spacer used has mortar pad, plastic cushion, reinforcing bar stirrup etc., and the defect that above cushion block exists has: cushion block place concrete is easy to crack, damaged; Cushion block is easily shifted, fragmentation, causes reinforcing steel bars exposed; Easily there is corrosion etc. in the fulcrum position of reinforcing bar stirrup.Above defect is more and more difficult to meet more and more higher construction reference, causes very large puzzlement to engineering construction and examination.
Summary of the invention
The utility model for above deficiency, propose a kind of Stability Analysis of Structures, simple to operate, firmly concrete cover cushion block is installed.
The purpose of this utility model is achieved in that concrete cover cushion block, it is formed by the cushion block unit grafting cooperation of two and half round pies, the diameter center of each cushion block unit forms semicircular reinforcing bar containing hole, and the both sides of reinforcing bar containing hole form boss and the concave station with boss Corresponding matching respectively; Each cushion block unit is provided with at least one colligation hole.
Further, described boss has the free end that size increases, and free end is any one of oval, square, circular, triangle or other irregular figures, and the shape of concave station is all corresponding with the shape complementarity of boss.
Further, described cushion block unit is concrete mats module unit.
The utility model adopts grafting fit system to form patty cushion block, has the following advantages: 1. structure is simple, convenient and simple for operation; 2. ensure the uniformity of thickness of concrete cover; 3. install firmly, be not easy to come off after grafting is good, after reinforcing bar and cushion block colligation, prevent cushion block to be shifted.
Accompanying drawing illustrates: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is the structural representation of the first cushion block unit;
Fig. 2 is the structural representation that two cushion block unit grafting coordinate;
Fig. 3 is the structural representation of the second cushion block unit.
Legend: 1. cushion block unit, 2. colligation hole, 3. reinforcing bar containing hole, 4. boss, 41. boss free end, 5. concave stations.
Detailed description of the invention: the utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment 1: as shown in Figure 1-2, concrete cover cushion block, it is formed by the cushion block unit 1 grafting cooperation of two and half round pies, the diameter center of each cushion block unit 1 forms semicircular reinforcing bar containing hole 3, and the both sides of reinforcing bar containing hole 3 form boss 4 and the concave station 5 with boss 4 Corresponding matching respectively; Each cushion block unit 1 is provided with two colligation holes 2; Boss 4 has the free end 41 that size increases, and in the present embodiment, the shape of free end 41 is oval, and the shape of concave station 5 and the shape of boss 4 are all like mushroom.
During use; first according to the designing requirement of Minimum Concrete Protective Coating Thickness; select sizeable cushion block unit 1; first piece of cushion block unit 1 is first placed below reinforcing bar; reinforcing bar is placed in reinforcing bar containing hole 3; second piece of cushion block unit 1 carries out grafting with first piece of cushion block unit 1 above reinforcing bar, penetrates tie and be connected and fixed reinforcing bar and cushion block unit 1 in colligation hole 2, and the area of every square metre can be laid 4-6 group cushion block and can meet construction requirement.
The utility model is installed, colligation is not only simple but also firm, compared with other cushion blocks, installs and cage of reinforcement position regulation has saved the twice above time at cushion block.
More firm in order to make the utility model be combined with concrete, cushion block unit 1 all adopts concrete to make, because the material of cushion block unit 1 is identical with concrete, strong adhesion, the coefficient of expansion is consistent, even if stream curing does not also produce gap, completely to combine together with concrete, the corrosion of steel bar effectively preventing the infiltrations such as air, rainwater, seawater from causing or concrete come off, and have no the sorrow of mortar pad and plastic cushion, substantially increase durability and the safety of steel concrete.
Embodiment 2: as shown in Figure 3, each cushion block unit 1 is provided with a colligation hole 2, and the shape of boss free end 41 is square, and the shape of concave station 5 and the shape of boss 4 are all like T-shaped.All the other are all identical with embodiment 1.
Obviously, above-mentioned explanation of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.Every belong to the technical solution of the utility model the apparent change of amplifying out or variation be still in the row of protection domain of the present utility model.
