Description

A kind of steel mesh and plastic plate combine the hollow building cover of pore-forming

Technical field

The application relates to the non-hollow building cover taking out heart pore-forming of a kind of Cavity structural member, is specifically related to the hollow building cover that a kind of steel mesh and plastic plate combine pore-forming.

Background technology

At present in cast-in-situ reinforced concrete hollow floor technical field, the Cavity structural member pore-forming moulding by casting hollow building cover of the all-sealed or light solid formula of usual employing, as the ZL200410082381.9 " a kind of hollow floor slab with small dense ribs " that inventor declares, adopt all-sealed thin-wall box body Cavity structural member to be embedded in floor slab with small dense ribs and form " T font " stressed cross-section hollow layer, solve the problem that " T font " stressed cross section little hollow-ribbed floor top board is smooth.But do not design steel bar stress bottom all-sealed thin-wall box body Cavity structural member and between hollow building cover template, one deck cracking resistance gauze wire cloth to be applied separately, again owing to adopting all-sealed thin-wall box body as Cavity structural member to realize little hollow-ribbed floor, hermetic thin-wall box body buoyancy is large; it is long that thin-wall box body makes the setting and hardening time; mould utilization factor is low; the large matter weight of thin-wall box body density, the defects such as production and transport inconvenience and thin-wall box body globality difference cracky.

Inventor has invented again the hollow building cover (ZL201320466241.6) of the netted box component pore-forming of a kind of combined type, make full use of concrete surface tension force, changing mesh shape does not allow concrete mortar permeate in netted combination Cavity structural member, utilize the netted box component of packing less combined type to substitute prior art hermetically sealed hollow cavity component or the solid Cavity structural member of polystyrene foam, overcome the defect that existing hollow building cover non-core-drawing pore-creating Cavity structural member exists; Reach that manufacturing speed is fast, production efficiency is high, with concrete plyability is good, cost is low, transport and easy construction, buoyancy are little, light weight, zero damaged, unshift, exempt and isolate cushion block and elongated fixing reinforcing bar etc.Achieve the breakthrough of hollow building cover new technology, become hollow building cover art innovative technology; But, the netted box component of combined type will bear the concrete pressure of working load and top flange, must to doing a large amount of supports and the shutoff of port in case, adopt steel pipe to make supporter and need inner a large amount of textural association, when adopting the shutoff of similar steel Web materials as port, binding site needs a large amount of welding, and combination difficulty is larger.

For solving the problem, inventor has invented again the cast-in-place hollow building < Application Number (patent) that a kind of steel mesh and polyphenyl block combine framework pore-forming: 201410181823.9 >, utilization development is a kind of has the superior one-tenth pole of hollow building cover overall performance, both concrete surface tension force had been made full use of, changing steel lattice shape does not allow concrete mortar infiltrate steel mesh, do not produce buoyancy, good with concrete relevance, strengthen structure stress, polyphenyl block is taked again to play a supporting role to steel mesh, steel mesh is made to bear the concrete normal pressure of working load and top flange, both combine, define steel mesh and polyphenyl block to combine framework and carry out the hermetically sealed hollow cavity component hole creating technology of alternative hollow building cover, but be used for specific function containing organic matter polyphenyl block Cavity structural member and build high fire prevention existence limitation, polyphenyl block delivery volume takies greatly the defect of carrying space.

Therefore, develop and a kind ofly have the superior one-tenth pole of hollow building cover overall performance, adopt steel mesh and plastic plate to be combined into the Cavity structural member of the pore-forming of cast-in-situ hollow building roof, its plastic plate also can adopt twice laid, saving energy; Both meet the advantage of inventor's prior art, overcome fire resistance rating when Cavity structural member that prior art steel mesh and polyphenyl block organic matter combine is built for specific function limited; When polyphenyl block supports empty in steel mesh, polyphenyl block density and capacity need be strengthened, improve compression capability, reduce the sex change amount of bearing working load; Polyphenyl block, when long-distance transportation, occupies loading space, strengthens cost; Polyphenyl block must make of the expandability plastic grain of standard, can not the defect of regenerated resource development and utilization; Optimize the hollow building cover prior art of steel mesh pore-forming, become the urgent need of hollow building cover art innovation.
