Abstract
The utility model relates to a reinforced concrete isolation cushion block, which is used for a reinforced concrete structure floor slab or a bearing bar in the construction of a wall column, so as to cause a steel bar and a molding board to be isolated. The cushion block comprises a cylindrical body made of concrete, an upper end face of the body is provided with at least one groove to support the steel bar. The cushion block is made of concrete by pressing molding and cast technology, and is convenient to fabricate, low in cost, high in strength and can be integrated with a parent body and no medium step or crack can occur and the reinforced concrete has better durability, bearing capacity, acidproof and alkali-proof performance and fireproof performance, etc..
Description
Technical field
The utility model relates to a kind of steel concrete with isolating cushion block, is used for construction bearing bars such as the floor of reinforced concrete structure or wall column, makes reinforcing bar and concrete blinding isolated.
Background technology
In the building operations; carrying out reinforced concrete structure floor or wall column etc. when building; for making reinforced concrete protective layer reach certain thickness; guarantee the bearing capacity of reinforcing bar in engineering structures; must use the cushion block bearing bar; make cushion block between reinforcing bar and template, keep certain distance, prevent that reinforcing bar from directly contacting with template with template.At present, this cushion block adopts plastics to make more, because plastics and steel concrete are diverse media, the two intensity durability, caking property have a long way to go, especially concrete initial set thermalization reaction, the plastic expansion coefficient is big, make the concrete floor or the body of wall of building structure around plastic cushion, produce the slit easily, with the passage of time, air enters into inside configuration and then corrosion reinforcing bar by the gap, particularly plastic cushion is used for underground concrete structure and has endless trouble especially, and there are a lot of problems in existing in addition plastic cushion unreasonable structure in the use.
Summary of the invention
The purpose of this utility model provides a kind of intensity height, and the steel concrete of being convenient to construct is isolated cushion block, and it can be integral with the steel concrete strong bonded, makes concrete structure have more performances such as durability, bearing capacity, acid and alkali-resistance and fire prevention.
This cushion block comprises the cylindrical body of being made by concrete, and the upper surface of body is provided with at least one groove that is used for the support reinforcing bar.
Said groove comprises two grooves that cross one another.
Said two grooves that cross one another intersect at grade.
One in said two grooves that cross one another is deep trouth, and another is a shallow slot, and the two is staggered on Different Plane.
Said body can be the taper cylinder that has tapering, makes placement more firm.
Said cylindrical body is provided with radial direction through hole, and when cushion block was used for constructing on vertical plane, this radial direction through hole was used to penetrate steel wire, is convenient on upright reinforcing bar colligation and fixes.
The lower surface of cushion block can be plane or concavo-convex some contact surface.
This cushion block by the pea gravel concreten pressing mold, build moulding, easy to make, cost is low, it is identical with member parent medium, can be one with the parent strong bonded, medium terrace and crack can not occur, and cushion block and parent have same high intensity, even little to the thick cushion block of 15mm, be used under the fertile beam of slab, cushion block can be not broken yet; This cushion block also can be on facade by steel wire cross-under location, be used for the site operation of indoor and outdoor member such as wall column, make the wall column cushion block be adjacent to reinforcing bar and be convenient to tighten, changed the traditional handicraft of making at the construction field (site) in the past, simplified operation, make construction more convenient.

Among each figure, 1-cushion block body, 2,2 '-groove, the 3-through hole.
The specific embodiment
Further specify cushion block embodiment of the present utility model below with reference to the accompanying drawings.
In illustrated each example, cushion block body 1 is slightly tapered cylinder, be equipped with two grooves 2 and 2 of right-angled intersection ', each groove is used for bearing bar.
Among Fig. 1～Fig. 3 embodiment, groove 2 is deep trouths, 2 ' be shallow slot, reinforcing bar supported in two grooves is staggered on Different Plane.
Among Fig. 4～Fig. 6 embodiment, groove 2 and 2 ' all be shallow slot, two shallow slots intersect at grade.
Among Fig. 7～Fig. 9 embodiment, groove 2 and 2 ' all be shallow slot, two shallow slots intersect at grade; In the present embodiment, cushion block body 1 also is provided with a radial direction through hole 3, and this cushion block more is applicable to the making of facade reinforced concrete members such as wall column, and cushion block penetrates steel wire by hole 3, subsequently corresponding to the groove reinforcement placing of cushion block, and by steel wire cushion block is tightened on reinforcing bar.
Parameters such as the number of the post height of the utility model cushion block (being the thickness of cushion block), diameter, groove or the degree of depth of groove, width can be designed to different size according to the employed occasion of cushion block.The intensity of cushion block can be divided into various strength specification such as C30, C40, C50, C60.
The bottom surface of body 1 can be more smooth plane, also can be irregular some contact surface, and the concrete that latter's cushion block is more conducive to and builds is combined as a whole.
