Abstract
The utility model discloses a kind of cushion block of concrete bar protective layer, comprise two supporting legs and middle supporting section, supporting section two ends are connected with the middle and upper part of two supporting legs respectively, the top of supporting section is provided with the groove for supporting top reinforcement, forms the arch be erected at above lower floor's reinforcing bar between the bottom of supporting section and two supporting legs; The top of one of them supporting leg is provided with extension upwards, and the upper transverse plane of extension is identical with needing the thickness of the cast-in-place double layer reinforced concrete floor of building to the distance of supporting leg lower end plane; Advantage is on the basis of existing topping cushion block; one of them supporting leg is arranged extension upwards; and make the upper transverse plane of extension identical with the thickness of cast-in-place double layer reinforced concrete floor needing to build to the distance of supporting leg lower end plane, thus constructor is known judge whether concreting thickness reaches the thickness calibration of floor requirement.
Description
Technical field
The utility model relates to a kind of building supplementary structure, especially relates to a kind of cushion block of concrete bar protective layer.
Background technology
That cast-in-place double layer reinforced concrete slab thickness controls is difficult, top reinforcement protective layer thickness is excessive is common quality defect common in building operations, how to guarantee protective layer of floor slab and slab thickness disposable up to standard be the technical barrier of puzzlement construction enterprises always.And be ensure double steel bar Stability Analysis of Structures; multiple topping cushion block S1 is as shown in Figure 1 placed in general meeting stage by stage below reinforcing bar; be made up of symmetrically arranged two supporting legs and middle supporting section; supporting section two ends are connected with the middle and upper part of two supporting legs respectively; the top of supporting section is provided with the groove for supporting top reinforcement, forms the arch be erected at above lower floor's reinforcing bar between the bottom of supporting section and two supporting legs.Therefore, how to transform this topping cushion block, what reach that protective layer of floor slab and slab thickness build is disposable up to standard, guarantees that cast-in-place double layer reinforced concrete floor high-quality is the recent goal in research of industry technician.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of thickness that can promote cast-in-place double layer reinforced concrete floor and topping thereof and builds disposable cushion block of concrete bar protective layer up to standard.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of cushion block of concrete bar protective layer, comprise two supporting legs and middle supporting section, supporting section two ends are connected with the middle and upper part of two supporting legs respectively, the top of supporting section is provided with the groove for supporting top reinforcement, forms the arch be erected at above lower floor's reinforcing bar between the bottom of supporting section and two supporting legs; The top of one of them supporting leg is provided with extension upwards, and the upper transverse plane of extension is identical with needing the thickness of the cast-in-place double layer reinforced concrete floor of building to the distance of supporting leg lower end plane.
Compared with prior art; the utility model has the advantage of on the basis of existing topping cushion block; one of them supporting leg is arranged extension upwards; and make the upper transverse plane of extension identical with needing the thickness of the cast-in-place double layer reinforced concrete floor of building to the distance of supporting leg lower end plane; thus constructor is known judge whether concreting thickness reaches the thickness calibration of floor requirement, guarantee that the thickness of floor and topping thereof is disposable up to standard.
As preferably, the supporting section below groove being provided with the first through hole that the iron wire for fixing top reinforcement for colligation passes, the supporting section above arch being provided with the second through hole that the iron wire for fixing lower floor's reinforcing bar for colligation passes.Make double steel bar structure more stable, guarantee the protective layer thickness of upper and lower layer reinforcing bar, improve the quality of cast-in-place double layer reinforced concrete floor.
Accompanying drawing explanation
Fig. 1 is the elevation of existing topping cushion block.
Fig. 2 is elevation of the present utility model.
Fig. 3 is top view of the present utility model.
Shown in figure: S1, existing topping cushion block, 11, supporting leg, 12, supporting section, the 121, first through hole, the 122, second through hole, 13, extension, 14, groove, 15, arch, 2, top reinforcement, 3, lower floor's reinforcing bar.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
This preferred embodiment is a kind of cushion block of concrete bar protective layer as shown in Figures 2 and 3, comprise two supporting legs 11 and middle supporting section 12, supporting section 12 two ends are connected with the middle and upper part of two supporting legs 11 respectively, the top of supporting section 12 is provided with the groove 14 for supporting top reinforcement 2, forms the arch 15 be erected at above lower floor's reinforcing bar 3 between the bottom of supporting section 12 and two supporting legs 11; The top of one of them supporting leg 11 is provided with extension 13 upwards, and the upper transverse plane of extension 13 is identical with needing the thickness of the cast-in-place double layer reinforced concrete floor of building to the distance H of supporting leg 11 lower end plane.
Preferably, the supporting section 12 below groove 14 being provided with the first through hole 121 that the tied silk for fixing top reinforcement 2 for colligation is passed, the supporting section 12 above arch 15 being provided with the second through hole 122 that the tied silk for fixing lower floor's reinforcing bar 3 for colligation is passed.
This cushion block of concrete bar protective layer preferably has C40 pea gravel concreten and waters ramming.
