Description
Technical field
The utility model belongs to civil engineering plant technical field, and in particular to a kind of high-strength profiled sheet-fiber reinforcement
Regeneration concrete compoboard.
Background technique
Regeneration concrete is to pass through the mass concrete block for having removed building to smash to pieces, the series of processes such as classification, production
At regenerated coarse aggregate, the natural aggregates such as sandstone are partly or entirely replaced, the new concrete that cement, water etc. are formulated is added
Material.Since the source of recycled aggregate is the concrete for having used and having discarded, itself contain certain cement mortar,
Cement mortar has lesser intensity and biggish porosity than rock, so the intensity of coarse aggregate will receive influence, regeneration is mixed
The intensity for coagulating soil decreases compared to normal concrete, but the prior art can reinforce the intensity of regeneration concrete, by this
Not only performance significantly improves regenerated coarse aggregate after reinforcement process, but also the regeneration of different intensity grades discarded concrete preparation
Coarse aggregate performance difference is not very greatly, the intensity of regeneration concrete to be made to be more easier to control；Simultaneously as regenerated coarse aggregate surface
Remain the mortar hardened, rock is compared in rough surface and gap a larger increase, to make the mobility of regeneration concrete
Reduce, coarse surface also increases regeneration concrete in mix and frictional resistance when pouring, and the bonding of regeneration concrete is strong
Degree and water retention property are higher than normal concrete.Since recycled aggregate density is less than natural rock density, regeneration concrete is compared
Reduce in the self weight of normal concrete, has very great help for mitigating building self weight.Research based on domestic and international lot of documents
The result shows that fundamental characteristics of recycled concrete can be applied to engineering structure close to normal concrete, compared to common coagulation
The brittleness of soil, regeneration concrete reduces, and toughness increases, and can significantly improve the thermal and insulating performance of building.In protection ring
In terms of border, regeneration concrete preferably solves dependence of the current building for natural coarse aggregate, greatly reduces natural thick
The demand of aggregate, and a better processing mode is had found for more and more construction waste concrete, make discarded mixed
Solidifying soil is reused, economic consumption and environmental pressure caused by reducing because of processing discarded concrete.
Existing armoured concrete slab site construction technology is complicated, and formwork is needed before casting concrete, reinforcing bar is arranged, under
Layer also not can be carried out construction for upper layer when reaching bearing capacity, lead to long construction period；Normal concrete has that tensile strength is low, the limit
The disadvantages of elongation percentage is small, property is crisp, anti-crack ability is poor, often the extension in crack has very big shadow to the bearing capacity of armoured concrete slab
It rings.
Utility model content
The utility model aim is to provide a kind of high-strength profiled sheet-fiber reinforcement regeneration concrete compoboard, solve
Currently common plate bearing capacity is lower, to meet requirement for bearing capacity and the excessive problem of sectional dimension.
The technical solution adopted in the utility model is a kind of high-strength profiled sheet-fiber reinforcement regeneration concrete compoboard,
Including fiber reinforcement regeneration concrete plate, fiber reinforcement regeneration concrete board bottom face offers multiple run through and parallel first is recessed
Slot, the high-strength profiled sheet of fiber reinforcement regeneration concrete board bottom face mating connection, high-strength profiled sheet one end extends to fiber increasing
Outside strong regeneration concrete plate, high-strength profiled sheet bottom surface parallel groove direction is welded with multiple rows of H profile steel beam.
The utility model is also characterized by:
Fiber reinforcement regeneration concrete plate is connect with high-strength profiled sheet by multiple rows of shear connector.
High-strength profiled sheet is steel plate with fiber reinforcement regeneration concrete board bottom face same shape, on high-strength profiled sheet
There are multiple second grooves, shear connector is welded in the second groove, shear connector can resist high-strength profiled sheet and fibre
Shearing between dimension enhancing regeneration concrete plate.
High-strength profiled sheet intensity is not less than Q460.
Shear connector is one of T-type rivet, square steel rivet, shape of a hoof rivet.
The beneficial effects of the utility model are:
(1) high-strength profiled sheet intensity is high, light, regular shape, is readily transported, stacks, and is easily portable and sets up, to applying
Work site requirements is smaller, can effectively reduce on-the-site labor, is arranged in below concrete slab and replaces in normal strength concrete slab
Reinforcing bar reduces workload at the construction field (site), gives full play to the advantage of high-strength steel, effectively promotes high-strength profiled sheet-fiber
The bearing capacity for enhancing regeneration concrete compoboard, achievees the purpose that the big bearing capacity of small size；
(2) permanent template of the high-strength profiled sheet as fiber reinforcement regeneration concrete plate is saved formwork in construction and is torn open
Die process can accelerate construction progress, and high-strength profiled sheet is flat because of the work for being alternatively arranged as subsequent construction with certain bearing capacity
Platform；
(3) fiber reinforcement regeneration concrete is under the support of high-strength profiled sheet, manufactured fiber reinforcement regeneration concrete
Plate is not required to thicker size, can reach the bearing capacity of requirement, while regeneration concrete has quality compared to normal concrete
Light feature effectively reduces the quality of building element；It effectively solves discarded concrete recycling simultaneously and aggregate does not have
There is the problems such as more preferable source, provides effective way for the recycling of discarded concrete, reduce the needs to natural sand stone, i.e.,
Environment is protected, and reduces construction cost；After fiber is added in regeneration concrete, since the tensile strength of fiber is big, prolongs
It stretches that rate is big, is improved tension, bending resistance, impact strength and the elongation percentage of fiber reinforcement regeneration concrete and toughness, makes it
It has a distinct increment compared to the cracking resistance with normal concrete, fiber, which is added, can control the further hair of original concrete crackle
Exhibition, to improve crack resistance, enhances the bearing capacity of the compoboard.
