Abstract
The in-situ cast reinforced concrete floor slab includes reinforced concrete and hollow core molds coated inside reinforced concrete. The hollow core molds are arranged alternately, connected by in-situ cast reinforced concrete ribs in between, upper in-situ cast reinforced concrete board and lower in-situ cast reinforced concrete board, and include pipe wall with foldable longitudinal hinge and movable support member. The hollow core molds have high strength and high rigidity, and may be folded for easy transportation. The present invention is suitable for in-situ cast or pre-stressed reinforced concrete hollow floor slab, roof, wall, foundation slab and hollow bridge, especially hollow flat floor slab.
Description
(1) technical field
The present invention relates to a kind of cast-in-place concrete cored.
(2) background technology
At present, in the prior art, it is permanent core that cast-in-situ reinforcing steel bar concrete hollow slab becomes pole, as paper tube, plastic pipe, metal bellows, core light material etc.These tubular core molds or member are mainly considered the concrete of finding time, and alleviate hollowcore slab weight.The patent No. as applicant's application is that ZL99249775.8, name are called the utility model patent of " cast-in-place reinforced concrete filling fiber reinforcement type thin wall cylinder ", it is made up of horniness thin-walled tube and two ends plug, two plugs form an enclosed cavity with the horniness thin-walled tube closed at both ends, this hard thin-wall tube wall is composited by carcass and cementitious materials, carcass can be glass fiber or carbon fiber or organic fiber or nonwoven or fibrous braid, and cementitious materials can be cement or organic resin or is the mixture of cement, filler, Admixture, fiber.This kind pipe has advantages such as intensity height, resistance to deformation, anti-vibration performance are good, convenient construction and transport.But this thin wall cylinder light-wall pipe as a whole, it is big to take up room in transportation, and the quantity of each transportation is few, and the freight height has increased the construction cost of cast-in-situ reinforcing steel bar concrete hollow slab undoubtedly.For this reason, the applicant on December 22nd, 2002 applied for that application number is 02158266.1, name is called the application for a patent for invention of " a kind of cast-in-situ reinforced concrete member ", this kind member is that two half of parts are fastened to form, half of parts can be improved plastics structural shape, in the end of member the baffle plate shutoff is arranged, on at least one half of parts, the joining parts are arranged, be fixed into integral body, can form hollow thin-wall component by the joining parts.Like this, half of parts can disposablely make at in-mold molding, it produces simple, convenient, and cost is low, simultaneously, this member can be assembled by half of position etc. at the construction field (site), thereby each parts occupation space in transportation is less relatively, and each freight volume is bigger, greatly facilitates carrying, reduced freight, the corresponding construction cost that reduces cast-in-situ reinforcing steel bar concrete hollow slab.But the half of parts of this hollow thin-wall component can not be folded into en plaque, therefore, occupation space is still bigger in transportation, and each freight volume is still less, thereby has increased substantially cast-in-place concrete cored cost, therefore, develop a kind of novel cast-in-place concrete cored for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of cast-in-place concrete coredly, have characteristics such as easy construction, cost is low, supporting capacity is big.
Solution of the present invention is on the basis of existing technology, comprise steel bar concrete, hollow-core mould, hollow-core mould is wrapped up in and is contained in the steel bar concrete, hollow-core mould is the cast-in-situ reinforced concrete rib alternately each other, is the cast-in-situ reinforced concrete upper plate on it, it is the cast-in-situ reinforced concrete lower plate down, hollow-core mould comprises tube wall, it is characterized in that having on the described tube wall vertical hinge of collapsible tube wall, and the hinge position has supports the also active supporting piece of fixed hinge.Like this, vertical hinge that collapsible tube wall is arranged on tube wall, when there is the active supporting piece of support and fixed hinge at the hinge position, hollow-core mould wall body intensity height, rigidity is big, resistance to compression, the shock resistance damage capability is strong, simultaneously, hollow-core mould can be folded into plate state and transport, loss and cost of transportation have been reduced, and, when described hollow-core mould is applied in the In-situ cast concrete board, admittedly but the member fixed hinge cut with scissors, thereby make hollow-core mould not yielding, guarantee the pouring quality of In-situ cast concrete board, be applicable to the hollowcore slab of various cast-in-situ reinforced concretes or prestressed reinforced concrete, hollow building cover, roof system, sole plate, body of wall and hollow bridges are used, and are specially adapted to hollow arch without beam and use.
Another solution of the present invention is on the basis of existing technology, comprise steel bar concrete, hollow-core mould, hollow-core mould is wrapped up in and is contained in the steel bar concrete, hollow-core mould is the cast-in-situ reinforced concrete rib alternately each other, is the cast-in-situ reinforced concrete upper plate on it, it is the cast-in-situ reinforced concrete lower plate down, hollow-core mould comprises tube wall, it is characterized in that having on the described tube wall vertical hinge of collapsible tube wall, and hollow unit has the support member that supports and make the body setting for the hinge position.Like this, vertical hinge that collapsible tube wall is arranged on tube wall, when hollow unit has support and makes the support member of body setting for the hinge position, support member has played the effect of good supporting drawknot to hollow unit, make hollow unit be difficult for deformed damaged, simultaneously, also improved the anti-pressure ability of hollow unit, the hollowcore slab, hollow building cover, roof system, sole plate, body of wall and the hollow bridges that are applicable to various cast-in-situ reinforced concretes or prestressed reinforced concrete are used, and are specially adapted to hollow arch without beam and use.
Another solution of the present invention is on the basis of existing technology, comprise steel bar concrete, hollow-core mould, hollow-core mould is wrapped up in and is contained in the steel bar concrete, hollow-core mould is the cast-in-situ reinforced concrete rib alternately each other, is the cast-in-situ reinforced concrete upper plate on it, it is the cast-in-situ reinforced concrete lower plate down, hollow-core mould comprises outer wall, and outer wall surrounds the enclosed cavity body, it is characterized in that the described fastener that turning joint and outer wall are arranged on the outer wall that has.Like this, when the fastener of turning joint and outer wall is arranged on the outer wall, the outer wall assembling combination becomes hollow unit convenient and swift, and assembling combination technology is simple, and, outer wall intensity height, rigidity is big, and is survivable, guaranteed the quality of hollow unit, the hollowcore slab, hollow building cover, roof system, sole plate, body of wall and the hollow bridges that are applicable to various cast-in-situ reinforced concretes or prestressed reinforced concrete are used, and are specially adapted to hollow arch without beam and use.
Feature of the present invention also is to have on the described hollow-core mould at least a in inner corner trim, chamfering, arc angle or the groove.Like this, when inner corner trim, chamfering, arc angle or groove are arranged on the hollow-core mould, Cast-in-place concrete has formed the Cast-in-place concrete reinforcing rib structure in above-mentioned inner corner trim, chamfering, arc angle and groove location, has further strengthened the load-carrying construction in the In-situ cast concrete board, has improved the weight bearing power of In-situ cast concrete board.
