Description

A kind of novel anti-crack Lightweight core mould

Technical field

Technical field of building construction is the utility model is related to, more particularly to a kind of novel anti-crack Lightweight core mould.

Background technology

Lightweight core mould hollow floor system, Lightweight core mould is put by being buried in plate, carried out according to design requirement with certain direction Simultaneously pouring molding is arranged, original solid superstructure is become hollow floor system, to save concrete amount, reduces construction costs, simultaneously And can enough increases building clear height, and improvement uses function, has the advantages that insulation, heat-insulated, sound insulation, and larger empty stomach rate causes Cast-in-place span of slab increase, weight reduction, reliability of structure, shock resistance performance are also improved.

Lightweight core mould can not often meet the requirement of cracking resistance in work progress due to the limitation of own material.In material In transportation of dispatching from the factory, handling and loading is improper easily to there is material breakage phenomenon；In material in situ installation course, operator Trample and easily cause material surface depression；In concreting process of vibrating, vibrating spear contact material surface is easily caused Material surface is damaged.The Crack Resistance that traditional lightweight core is taken is to smear pressure anticracking grout in material surface, then only in material Material and the extraneous upper surface composite glass fiber grid cloth being in the most contact.Although this local strengthening measure can bear concrete Evenly load, but for artificially trampling, the resistance effect for the load such as vibrating spear vibrates it is unsatisfactory, and due to glass The scope of glass fibrous mesh cloth envelope is limited only in a plane, therefore globality is poor, is especially easily being destroyed Corner location, edge damage arrisdefect phenomenon is of common occurrence.

Utility model content

For defect present in prior art or deficiency, it is light that the utility model innovatively proposes a kind of novel anti-crack Matter core, its solve well Lightweight core mould smear pressure anticracking grout composite glass fiber grid cloth after, can still go out in upper surface Now there is the problems such as edge damage arrisdefect in cracking and corner location, it is ensured that construction quality, improve economic benefit.

What the technical solution of the utility model was realized in：

A kind of novel anti-crack Lightweight core mould, the Lightweight core mould include pellet in the lightweight that inner core is foamed material, institute The surface for stating pellet in lightweight is provided with the first fiberglass gridding cloth, is set up on the surface of first fiberglass gridding cloth Separation layer, the second fiberglass gridding cloth of one layer of cladding upper surface and side is set up on the outside of the separation layer, described Waterproof layer is provided between separation layer and the second fiberglass gridding cloth newly established；In the lightweight inside of pellet from upper and Under be distributed with two layers of reinforcement, and two layers of reinforcement intersects setting；The center of pellet is provided with the lightweight Pouring hole, the top aperture of the pouring hole are less than bottom aperture；Pellet bottom is provided with for increasing lightweight in the lightweight Core bulk strength prevents the overcoat being broken in casting process.

Preferably, the cross section of the Lightweight core mould is square.

Preferably, the separation layer is bar-mat reinforcement, steel wire, organic fiber cloth, inorfil cloth and vegetable fibre net.

Preferably, the overcoat is cracking resistance grid cloth.

Compared with prior art, the beneficial effects of the utility model are：

The utility model discloses a kind of novel anti-crack Lightweight core mould, in order to overcome in existing work progress, Lightweight core mould The requirement that pressure anticracking grout composite glass fiber grid cloth can not meet to resist load and globality is smeared, still can be in upper surface There is the problems such as edge damage arrisdefect in cracking and corner location, and the utility model employs a kind of novel anti-crack Lightweight core mould, its Solve well Lightweight core mould smear pressure anticracking grout composite glass fiber grid cloth after, still can and side cracking in upper surface There is the problems such as edge damage arrisdefect in Angle Position, it is ensured that construction quality, improves economic benefit.

In the case of keeping the compound fiberglass gridding cloth size constancy of original Lightweight core mould upper surface anticracking grout, The fiberglass gridding cloth of one layer of envelope upper surface and side is set up on the outside of original fiberglass gridding cloth, increases glass fiber mesh newly Lattice cloth size is with Lightweight core mould upper surface size plus side height.In Lightweight core mould material and the extraneous upper surface being in the most contact Double glazing fibrous mesh cloth is set, can both bear the evenly load of concrete, and can limitation is artificially trampled, vibrating spear vibrates Etc. the influence of load, and outside increases fiberglass gridding cloth envelope upper surface and side simultaneously newly, to corner location Booster action is served, while also disclosure satisfy that the requirement of globality in transport of materials cargo handling process.The utility model construction party Just, can lifting construction speed, improve form removal after Surface Quality of Concrete, for response country call, promote novel building section Energy material, there is obvious society and economic benefit.
