Abstract

The utility model relates to a cast-in-place concrete steel wire net rack wall board. The cast-in-place concrete steel wire net rack wall board is composed of bilateral steel bar net pieces, fine steel wire nets attached on the inner side of a base, transverse short steel bars which are connected with the bilateral steel bar net pieces, a concrete sandwich layer poured in the middle of a made-up steel wire net rack, and cement mortar face layers smeared on the outer side of steel bar nets. Concrete poured in the middle of a steel bar net rack and cement mortar layers smeared on both sides of the steel bar net rack are firmly bond together with steel bar grids. The cast-in-place concrete steel wire net rack wall board can be conveniently and quickly installed at site without moulding boards. When the utility model is used, construction cost is saved, and quality is ensured, so the utility model has wide purposes.

Description

Cast-in-situ concrete steel wire net rack wallboard

The utility model relates to a kind of cast-in-situ concrete steel wire net rack wallboard, belongs to building material technology field.

Traditional materials for wall uses loam brick in a large number, and national wall changes policy for protecting farmland, and energy conservation has been forbidden loam brick, and materials for wall, particularly bearing wall material generally use cast-in-situ concrete, but have following weak point in construction at present.

(1) need wiretie at the construction field (site), and need to piece together the tower formation with a large amount of templates, the pouring concrete die cavity makes construction complicated again, and cost increases.

(2) die cavity of steel form formation, sidewall seals basically, and when fluid concrete, internal gas is difficult for overflowing, and causes the concrete leakiness, and construction need be vibrated, and when cast approached body of wall, the space was narrow, is not easy to the operation of vibrating.

(3), make the wall construction quality be difficult for seeing and look into, monitor because there is template support the body of wall both sides.In case occur could finding after the loose empty form removal, may cause the repairing even scrap of doing over again.

The purpose of this utility model is at above-mentioned weak point, design a kind of cast-in-situ concrete steel wire net rack wallboard, be mainly used in the interior body of wall of load-bearing of building, in factory, can produce steel wire net rack sheet material skeleton by batch, install at the scene, replace template, cast-in-place high flowability self-compacting concrete with steel wire mesh frame again, solidify the back and form the concrete bearing wallboard, this kind wallboard in construction saving of labor, material-saving, can reduce cost, ensure the quality of products.

The purpose of this utility model is that following proposal realizes: below in conjunction with Figure of description 1-2 scheme of the present utility model is described in detail:

The utility model cast-in-situ concrete steel wire net rack wallboard, form skeleton by the reinforced mesh (2,4) of both sides and the finer wire net (3,5) and the bar dowel (1) of reinforced mesh inboard, middle concrete sandwich layer (7) for sclerosis, the outside is cement screedn (6), be connected with spot welding between finer wire net (3,5) and the reinforced mesh (2,4), bar dowel (1) two ends are welded on the vertical reinforcement of reinforced mesh (2,4).

Reinforced mesh (2,4) is made by the reinforcing bar of diameter phi 2.5-φ 4mm.

Advantage of the present utility model:

(1) steel wire net rack can make earlier, in when construction, but cast on-site concrete sandwich layer (7) and smear cement sand bed (6), the scene is quick and easy for installation.Do not need a large amount of cast-in-place templates, reduced operating expenses.

(2) the cast-in-place steel wire net rack wallboard of the utility model mechanical property is good, and compressive strength can reach more than the 25MP, and whole anti-seismic performance is good.

(3) during casting concrete, air can be run out of from mesh, guaranteeing concrete compaction rate, and can observe directly the internal soundness of cast, is according to circumstances repaired, thereby has guaranteed the final mass of in-situ concrete wall.

(4) this kind wallboard can substitute for clay brick wall and other kind interior wall material, with its relatively, having can load-bearing, it is few to take building area, easy construction is ensured the quality of products, fully advantage such as fire prevention.

Description of drawings:

Fig. 1 is the drawing in side sectional elevation of the utility model cast-in-situ concrete steel wire net rack wallboard.

Fig. 2 is the rack perspective view of the utility model cast-in-situ concrete steel wire net rack wallboard.

Embodiment:

The used reinforced mesh of the utility model by diameter be φ 2.5-φ 4mm reinforcing bar anyhow vertically overlap joint be welded into the net sheet of rectangular mesh, size of mesh opening is 50-150mm * 50-150mm, the finer wire diameter of used finer wire net is φ 0.3-φ 0.5mm, mesh size is 3 * 3-8 * 8mm, horizontal bar dowel diameter phi 2.5-φ 4mm, length is 80-200mm, and concrete length is by the thickness of wall body decision of designing requirement.Every wallboard size can make wide 1.2m, and high 2.5-3.5m, thickness are the 80-200mm size.

In addition, according to the design needs, rack is middle also can be provided with reinforcing bar, this kind reinforcing bar is welded or ties up be fixed on the horizontal bar dowel (1), forms more firm space truss structure.The general configurable reinforcing bar that adds of highrise building, multistory building only need a small amount of configuration reinforcement, and low-rise building does not need configuration reinforcement.

Claims

1, a kind of cast-in-situ concrete steel wire net rack wallboard, it is characterized in that: form skeleton by the reinforced mesh (2,4) of both sides and the finer wire net (3,5) and the bar dowel (1) of reinforced mesh inboard, middle concrete sandwich layer (7) for sclerosis, the outside is cement screedn (6), be connected with spot welding between finer wire net (3,5) and the reinforced mesh (2,4), bar dowel (1) two ends are welded on the vertical reinforcement of reinforced mesh (2,4).

2, cast-in-situ concrete steel wire net rack wallboard according to claim 1 is characterized in that described reinforced mesh (2,4), is made by the reinforcing bar of diameter phi 2.5-φ 4mm.
