Abstract

The utility model provides a steel bar bracket for a concrete floor. The steel bar bracket is made of metal through integral molding and can stand independently. The upper end of the steel bar bracket is provided with a recessed upper steel bar support zone, the lower end of the steel bar bracket is continuously bent into two support legs and a lower steel bar support zone is concavely formed in the bending part. The traditional lower steel bar pads and other aids are not needed for support. Upper steel bars and lower steel bars can be supported simultaneously in a concrete floor project. In addition to the advantage of simple construction, support effects of the support zones are superior to support effects of commonly used steel bar supports.

Description

The concrete floor steel bar support

Technical field

The utility model is about a kind of concrete floor steel bar support, and the espespecially a kind of one-body molded innovation reinforcing steel supporting machine that can independently stand is the appurtenance that can support simultaneously the upper and lower part reinforcing bar.

Background technology

Be embedded with the fire prevention Poly Foam ball (VOID) that the light weight material is made in the hollow floor plate of general concrete steel building, to form the light weight floor; As shown in Figure 5, this sets up the upper reinforcement 100 and lower rebar 200 that disposes in length and breadth such as checkerboard type above template, settle fire prevention Poly Foam ball (not shown) therebetween, and pinion with metal fixing iron member 101 between the crisscross upper reinforcement 100, also pinion with metal fixing iron member 201 between the crisscross lower rebar 200; For avoiding upper reinforcement 100 to subside, several eyelid retractors 300 are installed to support upper reinforcement 100 in upper reinforcement 100 belows, in conjunction with shown in Figure 6, this eyelid retractor 300(is commonly called as reinforcing bar horse chair, English-word is Spacer) be metal material, its top has the Support 301 of a depression, and the feet 302 of four bendings is arranged at the bottom, is nested with respectively a plastics cover on this feet 302; In conjunction with shown in Figure 5, four feets 302 of eyelid retractor 300 belows prop up the Support 301 of template, top and withstand crisscross upper reinforcement 100, the dealer need only one metal fixing iron member 400 by 301 places, Support and upper reinforcement 100 bindings just can, so easy construction and simple.Yet above-mentioned eyelid retractor 300 is to be welded by the metal frame that two shapes are similar to ㄇ shape, does not have the characteristic that single metal frame is stood separately.

Moreover, for supporting lower rebar 200, concrete pad or plastic cushion (not shown) are installed, yet the in addition production of concrete pad and plastic cushion must separate manufacturing with the eyelid retractor 300 of upper reinforcement 100 between template and lower rebar 200, not only construction trouble, and time-consuming, cause cost to increase, and nonideal appurtenance, in addition, plastic plastic cushion has not met the requirement of concrete steel building.

Therefore, there is the dealer to develop a kind of floor slab reinforced support as shown in Figure 4, this support is comprised of steel bar spacer 500 and Steel bar rack 600, this steel bar spacer 500 is plastic products, which is provided with two jacks 501, jack 501 sides are provided with at least one groove 502, and wherein two jacks 501 can insert for metal Steel bar rack 600 bottoms, utilize the Support 601 of Steel bar rack 600 tops depression to withstand upper reinforcement 100; But groove 502 positions then supplemental support lower rebar 200(in conjunction with Fig. 5).Yet above-mentioned steel bar spacer 500 is plastic material, and itself structure can't firmly support outside crisscross upper reinforcement 100 and the lower rebar 200 except not durable, and this plastic material does not meet the requirement of concrete steel building yet; And steel bar spacer 500 and Steel bar rack 600 be different materials, must separately produce and make, and not only expends man-hour, labor intensive, also do not have economic benefit, haves much room for improvement.

The utility model content

Main purpose of the present utility model is to provide a kind of concrete floor steel bar support, a kind of by the metal frame Steel bar rack that Dan Zhike independently stands that is made of one piece, it is a kind of normalized eyelid retractor of being convenient to manufacture, be used on the template of hollow floor plate, can support simultaneously upper reinforcement and lower rebar that whole layer bears a heavy burden, except the constructability saving of work and time, the bearing capacity of its support is better than again traditional bearing bar, thereby a large amount of manufacturings of worth dealer and use.

A kind of concrete floor steel bar support, the Steel bar rack upper end is bent into a ㄇ shape, the upper reinforcement Support of its central tool one depression, and the lower end is bent into two feets, be arranged with reinforced bar support district, a bottom in the bending place, these two feets that bend continuously can independently be stood.

Preferably, put respectively a plastic sheath on two feets.

Preferably, Steel bar rack is that metal-made is made of one piece.

The specific embodiment

As shown in Figure 1, Steel bar rack 10 of the present utility model is concrete floor reinforcing steel supporting machines that a kind of metal-made is made of one piece, these Steel bar rack 10 upper ends are bent into a ㄇ shape, the upper reinforcement Support 11 of its central tool one depression, the lower end is bent into two feets 12, be arranged with reinforced bar support district, a bottom 13 in the bending place, this Curved Continuous is converted into irregular feet 12 and must just can stand by his thing, do not need assisting by steel bar spacer yet, just can stand independently, the Steel bar rack 10 that this metal material is made of one piece, except manufacturing simple and fast, be used in and be easy to again construction and installation on the concrete floor engineering, the bearing capacity of its support is better than again the steel bar spacer commonly used and the combination of Steel bar rack two-piece type.

The oxidation and rusting in order to prevent metal-made Steel bar rack 10 contact concrete floors, in conjunction with shown in Figure 2, on the feet 12 of Steel bar rack 10, cover last layer plastic sheath 20 with protection Steel bar rack 10, prevents oxidation and rusting.

In conjunction with shown in Figure 3, on concrete floor, set up the upper and lower part reinforcing bar 100 of in length and breadth configuration, 200 schematic diagram, when using Steel bar rack 10 of the present utility model, upper reinforcement 100 can be supported in the upper reinforcement Support 11 of this Steel bar rack 10, and the lower rebar Support 13 of two feet 12 lower ends bendings can be supported lower rebar 200 jointly, its construction is very simple and easy, and does not need by traditional appurtenances such as lower rebar cushion block.

In sum, the utility model concrete floor steel bar support, it is the Steel bar rack that a kind of metal-made is made of one piece, this Steel bar rack can independently be stood, can the regularization a large amount of Steel bar racks of manufacturing, can install simultaneously and prop up the upper and lower part reinforcing bar, except constructability, its support effect is better with the two-piece type combination of Steel bar rack than traditional type steel bar spacer again.

The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
