Abstract
The utility model relates to a reinforcing bar protective layer cushion block for building, which belongs to building construction cushion blocks for a concrete reinforcing bar protective layer, and includes a cushion block body, wherein a groove for clamping a reinforcing bar is arranged on one surface of the cushion block, the downward concave depth of the groove and the internal diameter of the groove are greater than the width of the opening of the groove, and the width of the opening of the groove is smaller than the diameter of the clamped reinforcing bar. The reinforcing bar protective layer cushion block has a simple structure, and is easy to mount and firm to fix; the contact surface area of the reinforcing bar and the cushion block is enlarged after the reinforcing bar is clamped in the groove, which greatly facilitates mounting and fixing of the cushion block; especially, as the shape of the inner side of the groove is matched with the diameter of the reinforcing bar, and the opening of the groove is slightly smaller than the diameter of the inner side of the groove, the clamping effect of the cushion block groove clamped with the reinforcing bar is enhanced, and great convenience is brought to building workers for mounting the cushion blocks in the building industry. As long as the cushion block is pressed to the reinforcing bar, the mounting is accomplished without the trouble of binding, and as a result, the reinforcing bar protective layer cushion block for building is time-saving, labor-saving and cost-saving.
Description
Technical field
The utility model belongs to building field, and particularly a kind of construction steel tendon protective layer cushion block is the building operations cushion block that steel reinforced concrete protective layer uses.
Background technology
The reinforcement cover cushion block is that the modern architecture construction field uses modal constructional materials.Cushion block is usually with plastics (regenerated plastics), and mortar or other plurality of raw materials are the basis, make through various manufacturing process.Cushion block is mainly used in the support use of steel reinforced concrete protective layer in building operations.
Plastics, the mortar cushion block major part of producing all is cuboid and cylindrical structure now, six faces all are the planes, such structure can cause the inconvenience in many uses, for example during reinforcing bar binding, will be with cushion block by quincuncial arrangement, one one fast with burning the silk colligation at rebar surface, but careless slightlyly particularly can occur dropping when grouting, damage, fixing not firm, easy deformation, time-consuming.
Summary of the invention
The purpose of this utility model is to propose a kind of construction steel tendon protective layer cushion block technical scheme, the cushion block that this scheme provides a kind of surface to have draw-in groove, draw-in groove be arranged on the reinforcing bar contact surface on, this cushion block is simple in structure, use is convenient.
To achieve these goals; the technical solution of the utility model is: a kind of construction steel tendon protective layer cushion block; comprise a cushion block body; on a face of cushion block body, be provided with the groove that is used to snap in reinforcing bar; the recessed degree of depth of groove and groove internal diameter are greater than groove mouth A/F, and the width of rebate of described groove is less than the described bar diameter that snaps in.
Described groove internal diameter equals the described diameter that snaps in reinforcing bar, and described width of rebate is less than the groove internal diameter or snap in bar diameter 2mm to 3mm.
Described cushion block body is the type shape, and described groove is arranged on the protruding narrow side of type shape cushion block body.
Described cushion block body material is plastics.
The beneficial effects of the utility model are: simple in structure, be easy to install, fixed, groove is set on cushion block, the contact surface that has objectively increased reinforcing bar and cushion block after reinforcing bar snaps in groove is long-pending, make when cushion block is installed, because the increase of the contact area between reinforcing bar and the cushion block, be very beneficial for the installation of cushion block and fixing, especially inboard shape of described groove and bar diameter mate mutually, the groove mouth is slightly less than the groove inside diameter, formed the clamping effect of cushion block groove after snapping in reinforcing bar the time especially, brought great convenience when cushion block being installed for the construction worker of building trade.The workman gets final product installation as long as cushion block one is pressed on the reinforcing bar.Can guarantee the requirement of thickness of protection tier, cushion block is clamped on need not to carry out again colligation on the reinforcing bar, save time, laborsaving, province's expense.
Below in conjunction with drawings and Examples the utility model being done one describes in detail.
Description of drawings
Fig. 1 is a perspective view of the present utility model;
Fig. 2 is a user mode schematic perspective view of the present utility model.
The specific embodiment
A kind of construction steel tendon protective layer cushion block embodiment; referring to Fig. 1 and Fig. 2; described cushion block is that the unsettled pad of steel bars in concrete layer risen; steel bar layer remains in the concrete and does not misplace when guaranteeing fluid concrete; described for this reason cushion block comprises a cushion block entity 1; on a face of cushion block body, be provided with the groove 1-1 that is used to snap in reinforcing bar 2; the recessed degree of depth of groove and groove internal diameter are greater than groove mouth 1-1-1 A/F; for firmly not coming off from reinforcing bar after the cushion block installation, the width of rebate of described groove is less than the described bar diameter that snaps in.
For the reinforcing bar that guarantees to snap in is clamped by groove, in the application of present embodiment, described groove internal diameter equals the described diameter that snaps in reinforcing bar, and described width of rebate is less than the groove internal diameter or snap in bar diameter 2mm to 3mm.
Because the difference of steel bar layer reticular density, when snapping in reinforcing bar for groove at cushion block, the cushion block on groove next door can not exert an influence to other adjacent reinforcing bars, it is narrow to try one's best in the position of cushion block body band groove side, insert with convenient, therefore the described cushion block body is made is the type shape, and described groove is arranged on the narrow side of type shape cushion block body projection.
Because groove is young in the groove inside diameter, and the diameter of reinforcing bar just with groove in through identical, therefore require cushion block should have certain elasticity, reinforcing bar could snap in groove from the groove mouth like this, what therefore described cushion block body material used is plastics, can adopt die production during making.
Fig. 2 is the stereogram of the actual use of present embodiment cushion block, wherein cushion block is a rectangle body, cushion block body intermediate projections is the type shape, on raised surface, be provided with groove, the size of groove mouth is equal to or slightly less than the diameter of reinforcing bar, the internal diameter of groove equal reinforcing bar diameter, thereby groove internal diameter and bar diameter can be mated mutually.When assembling reinforcement, cushion block groove alignment reinforcing bar once by realizing the nested type coupling, is not only helped the control location of protective layer thickness, and helps by the engagement of groove card and reinforcing bar fixed like this.
The setting of cushion block groove as mentioned above, the effect of existing location has the effect that enlarges contact area again.Therefore, give building trade construction bring convenience, can enhance productivity greatly.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
