Abstract

The utility model relates to a stripped steel bar split heads which comprises a transversal split heads barrier bar made by a steel bar. A plurality of split heads support legs are fixedly connected on the transverse split heads barrier bar; each split heads support leg is fixedly connected with a split heads support foot; the split heads support feet are in the arrangement vertical to the split heads support legs, the upper layer of steel bars and the lower layer of steel bars of a cast-in-place concrete plate can be ensured to be supported stably, the accurate position can be ensured, the sufficient stability and carrying force can be ensured, the steel bar twisting and depressing of the upper part of the cast-in-place concrete plate can be avoided, the protective layer thickness of theupper layer of steel bars can be ensured, and the casing quality of the cast-in-place concrete plate is improved.

Description

Bar shaped reinforcing bar split heads

Technical field

The utility model relates to a kind of building unit; relate in particular to the upper and lower two-layer reinforcing bar of a kind of energy cast-in-place plate of stable support, guarantee upper strata negative bending moment rib protective layer thickness; improve cast-in-place plate pouring quality, and handled easily build the working bar shaped reinforcing bar of cast-in-place plate split heads.

Background technology

The quality control of cast-in-place slab tendon protective layer thickness is an important step of guaranteeing the major project construction quality; bar shaped reinforcing bar split heads is absolutely necessary as the measure reinforcing bar of cast-in-place plate; from technology and economic angle, also hold the balance; be used in the middle of the upper and lower two-layer reinforcing bar of cast-in-place plate, rise support, fixing top plate action of steel bars.Current, more and more stricter to the protective layer thickness requirement of structural solid, how especially cast-in-place plate negative bending moment rib protective layer thickness accomplishes that better controlled is a difficult point in the practical operation always.In the cast-in-place board member construction such as raft foundation, cast-in-situ floor; because reinforcing bar stirrup of the prior art is irregular, stability and bearing capacity are not enough; it is commonplace that the operator tramples the phenomenon of reinforcing bar; very easily cause plate upper reinforcement distortion and sagging; the stirrup of some bearing bar even trampled on; some stirrup itself is made just lack of standardization; can not guarantee plate top reinforcement protective layer thickness; be directly connected to situations such as the bearing capacity of reinforcing bar in the concrete work structure, durability, acid and alkali-resistance, influence workmanship.

The utility model content

Problem to be solved in the utility model is at deficiency of the prior art, provides that a kind of stability is high, bearing capacity is strong, can effectively improve the bar shaped reinforcing bar split heads of cast-in-place plate pouring quality.

For overcoming the above problems, the technical solution adopted in the utility model is: bar shaped reinforcing bar split heads, it is characterized in that: described bar shaped reinforcing bar split heads comprises a split heads crosspiece muscle with reinforcement fabrication, be fixedly connected with several split heads support legs on the described split heads crosspiece muscle, be fixedly connected with the split heads spike on described each split heads support leg, described split heads spike supports with split heads that leg is vertical to be provided with.

The further optimization of technique scheme, described split heads crosspiece muscle split heads crosspiece muscle vertically is provided with.

A kind of concrete prioritization scheme, the quantity of described split heads support leg is 3.

The utility model is taked above technical scheme; have the following advantages: the upper and lower two-layer reinforcing bar that can guarantee the cast-in-place plate of stable support; the assurance position is accurate; have enough stability and bearing capacity; avoid plate upper reinforcement distortion and sagging; guarantee plate top reinforcement protective layer thickness, improve cast-in-place plate pouring quality.

Below in conjunction with the specific embodiment to the technical solution of the utility model further instruction

The specific embodiment

Embodiment; below in conjunction with view the utility model is described in detail; as shown in the figure; bar shaped reinforcing bar split heads comprises a split heads crosspiece muscle 1 with reinforcement fabrication; vertical welding is connected to 3 split heads support legs 2 on split heads crosspiece muscle 1; welding split heads spike 3 on the split heads support leg 2; split heads spike 3 supports leg 2 with split heads respectively; split heads crosspiece muscle 1 is vertical; split heads spike 3; the reinforcement fabrication of split heads support leg 2 and split heads crosspiece muscle 1 usefulness Φ 16 above same sizes; at the weld brushing rustproof paint of bar shaped reinforcing bar split heads, the height of bar shaped reinforcing bar split heads is cast-in-place plate thickness-plate protective layer thickness-top reinforcement diameter.

During use, after cast-in-place plate lays template, colligation lower floor of elder generation steel mesh reinforcement, again this bar shaped reinforcing bar split heads is placed on the template of cast-in-place plate, top mat is shelved on the split heads crosspiece muscle 1 of bar shaped reinforcing bar split heads, and the stirrup crosspiece muscle 1 usefulness colligation silk colligation of top mat and bar shaped reinforcing bar split heads is firm.
