Abstract

The utility model discloses a steel bar positioning clip, and is characterized in that the clip consists of an upper part and a lower part; and the upper part is a clip (1) used to clamp a steel bar, and the lower part is a bracket (2). The clip has a star-shaped section, and the bracket is shaped like a bench. The clip is capable of accurately controlling the thickness of the protective layer of a sheet bar, as well as the height of the space between an upper sheet bar and a lower sheet bar. The utility model solves the difficulty in controlling the thickness of the protective layers of the steel bars of plates, columns, beams and walls in the cast-in-situ concrete project, brings to an end the coarse, preemptive and free operating status in the current construction, saves construction time, improves the working condition and enhances the production efficiency.

Description

A kind of bar spacers

The utility model relates to building cast-in-situ and precast member apparatus, specifically a kind of bar spacers.

The thickness of protection tier of control reinforced concrete structure has several ways at present, but all because of defective of self and the randomness poor effect when constructing.The one, a pad cement mortar prefabricated section: the easy fragmentation in work progress of this method becomes illusory; The 2nd, pad rubble or decorative board fragment: particle shape, size, variable thickness, jammed on or shaken easy landing, inaccessible design protection layer thickness, and decorative board fragment any surface finish bonds not good enough with cast-in-situ concrete; The 3rd, a short section of pad reinforcing bar waits and satisfies thickness of protection tier.Above-mentioned localization method was both inaccurate, unreliable, wasted resource again, also can stay hidden danger to engineering.The applicant is that 99231465.8 utility model patent has solved this problem preferably in the patent No. of first to file, but form is more single.

The purpose of this utility model provides a kind of bar spacers that can control the thickness of protection tier of beam, plate, post, wall, shell easily and accurately.

The utility model is achieved in that this bar spacers by two partly forming up and down, and top is the clamp that can block reinforcing bar, and the bottom is a bearing.Upper reinforcement clamp cross sectional shape is

Shape, Shape,

Shape,

Shape, and can play the different shape that blocks reinforcing bar.Lower seat is stool shape or other bearing that can play supporting role.Bar spacers of the present utility model mainly is used as reinforcing bar sheath card.

Locator card of the present utility model has following advantage:

1, the protective layer thickness of control panel muscle accurately.

2, solved the difficult problem of protective layer thickness control of plate, beam, post, wall reinforcing bar in the cast-in-situ concrete engineering; that the existing construction of being through with exists is extensive, original, the situation of random operation; impel above-mentioned link to realize standardization as early as possible, normalized construction and management.

3, save the engineering time, not colligation, quick and easy for installation, firm, defectives such as the cracked and distortion of no slippage are easy to inspection and manage, and have improved condition of work, have improved production efficiency;

4, save steel, lighter than reinforcing bar " short section ", every heavily about 5-6 gram.

Embodiment, the utility model bar spacers is by two partly forming up and down, and top is the clamp 1 that can block reinforcing bar, and the bottom is a bearing 2.

Shown in Fig. 1-12, the cross sectional shape of upper reinforcement clamp 1 can be a shape, shape, shape, shape, shape, the arbitrary shape in the shape; Lower seat is a stool shape, also can be that other can overspend the form of making usefulness.The connected mode of top and the bottom can be mash weld, also can be whole rolling.

During use, (1) is (or beam, post muscle tie the back) after the lower plywood muscle ties, according to the requirement of set-point, lower plywood muscle (or stirrup of beam, post) is aimed at this Ka Huxingkaikouchu, firmly one press, reinforcing bar promptly advances in the collar, and a seat leg 2 contact stencil planes are got final product.

Claims

1, a kind of bar spacers is characterized in that top is the clamp (1) that can block reinforcing bar by two partly forming up and down, and the bottom is bearing (2).

2, bar spacers according to claim 1 is characterized in that upper reinforcement clamp cross sectional shape is

Shape, Shape,

Shape,

Shape, Shape, Shape.

3, bar spacers according to claim 1 is characterized in that lower seat is a stool shape.
