Abstract

The utility model discloses a rebar cushion block, belongs to the field of construction products, and in particular relates to the rebar cushion block which is used for preventing rebar explosion in a concrete pouring process. The rebar cushion block comprises a rectangular cushion block main body (1) and is characterized in that grooves (2) are formed on the four edges of the cushion block main body (1) respectively, and the vertical distances from the bottoms to the opposite edges of all the grooves are different, so that the distances from the rebar to a cast-in-situ molding plate are regulated to generate four different heights by using different grooves (2) to support the rebar; the rebar cushion block is very strong in adaptability, and the construction cost is reduced; the grooves (2) are arc grooves, and the rebars at different specifications supported in the grooves (2) can not deviate. The rebar cushion block disclosed by the utility model is manufactured by using a concrete pressing die or is manufactured from a plastic steed material; the rebar cushion block can be manufactured from production waste, and has the advantages of strong adaptability, low cost and the like.

Description

Steel bar spacer

Technical field

Steel bar spacer, belong to building operations articles for use field, is specifically related to a kind of steel bar spacer that prevents reinforcing steel bars exposed when concreting.

Background technology

In construction work; the situation that needs concreting is often arranged; such as reinforced concrete protective layer; and the thickness relationship of reinforced concrete protective layer is to performances such as the bearing capacity of structure, durability, fire prevention; the too thin easy infiltration wet gas of topping and water, the blocked up crack that easily produces, these all may make corrosion of steel bar and expand; thereby concrete is wrecked, and impact is used and structural safety.Due to casting wire-tie and exterior sheathing between should maintain a certain distance, so often need to tie up betwixt a cushion block in reinforcing bar and outer template every a segment distance, reinforcing bar and outer template can be separated to certain distance.

Steel bar spacer commonly used often can only make reinforcing bar and outer template separate one, maximum two fixing distances at present, and existing building as required the distance between reinforcing bar and outer template a plurality of standards are arranged, current steel bar spacer bad adaptability, and it is higher to customize as required the cost of steel bar spacer.

Summary of the invention

The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of adaptable steel bar spacer is provided.

The technical scheme that its technical problem that solves the utility model adopts is: this steel bar spacer comprises and it is characterized in that the cushion block body of rectangle: on cushion block body four edges, offer respectively groove, each bottom portion of groove is not equidistant to relative edge's vertical distance.

Described this body section of cushion block is rectangle.

Described cushion block body is that the concrete pressing mold forms.

Described groove is deep-slotted chip breaker.

The width of described groove is less than the length on its limit, place.

The thickness of described cushion block body and the width ratio of groove are 0.5:1～3:1.

Wired hole is offered at described cushion block body middle part.

Described this body section of cushion block is square.

Described cushion block body is plastic-steel.

Each bottom portion of groove is respectively 3cm, 4cm, 5cm, 6cm to relative edge's vertical distance.

Compared with prior art, the beneficial effect that has of the utility model steel bar spacer is:

1, strong adaptability: by using different recess supports reinforcing bars, can adjust the four kind differing heights of reinforcing bar to template, extremely well-adapted, reduce building costs;

2, cost is low: by the concrete pressing mold, make, or adopt plastic-steel material to make, utilize production waste to make, cost is low.

The accompanying drawing explanation

Fig. 1 is the front elevation drawing schematic diagram of the utility model steel bar spacer.

Fig. 2 is the perspective view of the utility model steel bar spacer.

Fig. 3 is the structural representation with the steel bar spacer in line hole.

Fig. 4 is that the cushion block body is foursquare structural representation.

Wherein: 1, cushion block body 2, groove 3, line hole.

Fig. 1 ~ 2nd, the most preferred embodiment of the utility model steel bar spacer, be described further below in conjunction with 1 ~ 4 pair of the utility model of accompanying drawing.

The specific embodiment

With reference to accompanying drawing 1～2: this steel bar spacer, comprise that cross section is rectangular cushion block body 1, four angles of cushion block body 1 are fillet, on the four edges of cushion block body 1, offer respectively the groove 2 of arc, reinforcing bar is fallen the bottom of arc groove 2, can not produce skew, the groove 2 of arc can adapt to the reinforcing bar of different size, and compliance is stronger.

Each groove 2 bottoms are all not identical to relative edge's vertical distance, groove 2 bottoms in upper end are 6cm to the vertical distance on cushion block body 1 base, groove 2 bottoms in lower end are 5cm to the vertical distance of cushion block body 1 top margin, left end groove 2 bottoms are 4cm to the vertical distance of cushion block body 1 right edge, right-hand member groove 2 bottoms are 3cm to the vertical distance on cushion block body 1 limit, left side, when different like this grooves 2 is upwards placed bearing bar, reinforcing bar is 3cm respectively to the distance of template, 4cm, 5cm, 6cm, a kind of steel bar spacer can be adjusted four kinds of differing heights of reinforcing bar, extremely well-adapted, reduce building costs.

Cushion block body 1 forms for the concrete pressing mold, utilizes the production clout to make, and can reach the building requirements label, and easy to make, cost is low.The thickness of cushion block body 1 is different according to bar gauge from the width ratio of groove 2, can select 0.5:1～3:1, in the situation that firm bearing bar reduces and uses material as far as possible, reduces costs.

With reference to Fig. 3: can also at cushion block body 1 middle part, offer a line hole 3, line hole 3 is parallel with groove 2, be used to penetrating tie wire, reinforcing bar is carried out to colligation.

With reference to Fig. 4: cushion block body 1 can be square, by four grooves 2 are arranged to the different degree of depth, reaches the purpose of four kinds of differing heights adjusting reinforcing bar, and 1 four angles of cushion block body can be right angle.

Each groove 2 bottoms differ 1cm each other successively to relative edge's vertical distance, also can differ other length, to relative edge's vertical distance, are 2cm, 5.5cm, 4cm, 7.5cm as each groove 2 bottoms; Cushion block body 1 can be concrete material, can be also plastic-steel, and the utility model can be above any combination.

The above, it is only preferred embodiment of the present utility model, be not the utility model to be done to the restriction of other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away from, to any simple modification, equivalent variations and remodeling that above embodiment does, still belong to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
