Abstract
The utility model discloses a hollow cushion, including the cushion body, be provided with channel, recess on the cushion body, the channel setting is in hollow cushion's top and bottom, and the channel includes first channel, second channel, and the recess setting is at the outside middle part of cushion body. The utility model discloses a hollow cushion is by precast concrete, and the preparation is convenient, strength grade height, simple structure, reasonable in design, need not branchs when using about, the cushion is settled in atress reinforcing bar intersect department, stability is good, can not take place to shift, the prevention of seepage recess can prevent that concrete slab from following the cushion seepage, hollow cushion plays concrete slab gauge control simultaneously and acts on.
Description
Technical field
The utility model belongs to wood engineering field, is specifically related to a kind of hollow cushion block.
Background technology
Accurate in order to ensure the steel bar stress position in cast-in-situ reinforced concrete slab, need to arrange cushion block below steel bar stress, at the bottom of the upper placing of reinforcement distance plate of plate, height is comparatively large, and in Practical Project construction, general employing installs steel bar horse-shaped bench, plastic cushion, " X-type " concrete pad.Steel bar horse-shaped bench cost is higher, needs colligation time fixing; Plastic cushion intensity is low, easily damages in work progress, has weakening to armored concrete slab intensity; Easily topple over during the construction of " X-type " cushion block.
Utility model content
In order to overcome the deficiency in background technology, a kind of hollow cushion block of the utility model research and design, its object is to: provide that a kind of strength grade is high, cost is low, good stability, effectively control the hollow cushion block of concrete slab thickness.
Technical solution of the present utility model:
A kind of hollow cushion block, comprise cushion block body, it is characterized in that: described cushion block body is provided with conduit, groove, described conduit is arranged on top and the bottom of hollow cushion block, conduit comprises the first conduit, the second conduit, and described groove is arranged on the outer middle side part of cushion block body.
Described cushion block body shape is hollow cylinder or rectangular cylinder.
The height of described cushion block body equals the thickness of concrete slab.
The diameter of described first conduit, the second conduit is all greater than the maximum gauge of steel bar stress in concrete slab.
The beneficial effects of the utility model: hollow cushion block of the present utility model is by concrete prefabricated, easy to make, strength grade is high, structure is simple, reasonable in design, without the need to dividing up and down during application, cushion block is placed in steel bar stress crosspoint place, and good stability can not be shifted, antiseepage groove can prevent concrete slab along cushion block seepage, and hollow cushion block plays concrete slab thickness control action simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: cushion block body 1, first conduit 2-1, the second conduit 2-2, groove 3.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
A kind of hollow cushion block, comprise cushion block body 1, cushion block body 1 is provided with conduit, groove 3, conduit is arranged on top and the bottom of hollow cushion block 1, conduit comprises the first conduit 2-1, the second conduit 2-2, and groove 3 is arranged on the outer middle side part of cushion block body 1, and cushion block body 1 shape is hollow cylinder or rectangular cylinder, the height of cushion block body 1 equals the thickness of concrete slab, and the diameter of the first conduit 2-1, the second conduit 2-2 is all greater than the maximum gauge of steel bar stress in concrete slab.
Concrete use procedure: when the utility model is applied in engineering, according to Bars In Poured Concrete Slab thickness, steel bar stress diameter and strength grade of concrete precast hollow cushion block, the diameter of the first conduit, the second conduit is D, and the first channel depth is 2D+H
1, the second channel depth is D+H
1, H
1for thickness of protection tier; hollow cushion block of the present utility model is placed in steel bar stress crosspoint place; the inner side steel bar stress of plate is made to be positioned at the first conduit of cushion block; outside steel bar stress is positioned at the second conduit of cushion block; the utility model structure is simple; easy to make; without the need to dividing up and down during application; hollow cushion block is placed in steel bar stress crosspoint place; good stability; can not be shifted, antiseepage groove can prevent concrete slab along cushion block seepage, and hollow cushion block plays concrete slab thickness control action simultaneously.
To sum up, the utility model produces a desired effect.
