Abstract
The utility model provides a cavity superstructure component, including bottom plate and hollow box, the box is installed on the bottom plate, the bottom plate is reinforced concrete, has laid the fibre screen cloth in this reinforced concrete, the box includes the lateral wall and installs the upper cover on the lateral wall, the lateral wall is fixed on the bottom plate. The utility model discloses a reinforced concrete adopts hollow box as the upper portion member as the bottom plate, in effective control self weight, provides the efficiency of construction greatly, the reduction of erection time, be equipped with the fibre screen cloth at the concrete floor middle berth, use the fibre screen cloth can lighten the dead weight better and obtain better tensile strength to can fall reinforced concrete's thickness thinner.
Description
Technical field
The utility model relates to concrete hollow floor cast-in-site building unit, particularly relates to a kind of cavity building roof component.
Background technology
In order to alleviate the dead load of concrete building cover plate better, control the deflection deformation of floor, and save reinforcing bar, reduce comprehensive cost, to meet low-carbon (LC), energy-saving and environmental protection requirement, floor plan many employings cast-in-place concrete hollow floor slab technology, the one-tenth pole that it adopts, or claim internal mold, be divided into two classes, one class is hollow cylinder core casing, such as all kinds of thin-wall hollow pipe; One class is cylindrical shell, the block of light solid, such as, a kind of cast-in-situ concrete hollow building roof filling bar disclosed in Chinese patent ZL200720030993.2.
But, existing all kinds of hollow thin-wall pipe fitting is when floor slab construction, not only need the top concreting at thin-wall pipe, the bottom of thin-wall pipe also needs concreting, otherwise the floor formed cannot the object such as ceiling-mounted light, and because thin-wall pipe is thinner, material many uses fiber mesh cloth adds cement paste and is formed, be easy to smash up, resident family is easily allowed to think corrupt building practices, there is hidden danger of quality, to bottom thin-wall pipe during concreting, due to the stop of thin-wall pipe, very difficult vibrating head carries out tamping, easily there is concrete leakiness and produce qualitative problems of construction, during this external construction, need the anti-floating problem considering thin-wall pipe, light thin-wall pipe fitting easily floats when concreting.Such as, Chinese patent ZL201020176648.1 discloses a kind of inorganic flame retardant composite box for filling hollow floorslab, comprise light solid casing, and be coated on the hard shell of light solid box outer surface, described hard shell is at least to include one deck fiber mesh layer, and the inorganic composite bed adopting polymer water mud or polymer cement mortar to be formed, the side that light solid casing two is relative arranges anti-floating draw piece, utilizes anti-floating draw piece to be fixed on reinforcing bar by casing.
Summary of the invention
For solving prior art Problems existing, the utility model provides a kind of cavity building roof component, when floor construction, without the need to cast-in-situ concrete bottom obturator, and convenient construction, significantly reduction of erection time.
The cavity building roof component that the utility model provides, comprises base plate and hollow box body, and described casing is arranged on base plate; Described base plate is armored concrete slab, is equipped with fiber mesh cloth in this armored concrete slab; Described casing comprises sidewall and is arranged on the upper cover on sidewall, and described sidewall is fixed on base plate.During construction, tie up waffle beam reinforcing bar, installed concrete blinding, directly the utility model has been placed on bed die, then carried out the binding reinforcing bars on superstructure surface, then carry out concreting.Because the utility model base plate is armored concrete slab, can directly load-bearing, without the need to concreting below base plate.Arranging fiber mesh cloth can the intensity of reinforcing steel bar concrete slab, and especially adopt thinner armored concrete slab, fiber mesh cloth has good effect of prestressed.
Because casing is arranged on reinforced concrete floor, for cost-saving, described casing is without bottom surface casing.
For strengthening the intensity of casing, avoiding causing damage in transport and work progress, improving crush resistance strength, be provided with support member in described casing, this support member is arranged between two parallel sidewalls, and the quantity of support member is arranged according to the size of casing.
For making the utility model merge with cast-in-situ concrete better, the reinforcing bar of described base plate stretches out base plate, during construction from the sidewall of base plate, the reinforcing bar stretched out outside base plate is stretched in waffle beam reinforcing bar, and tie up by tied silk, after concreting, waffle beam and reinforced concrete floor are lumped together.
The connection of sidewall and base plate for convenience, described sidewall is connected with base plate by fixture, sidewall and fixture is fixed, then is fixedly mounted on base plate by fixture.
Casing both can adopt integral structure, also can adopt split type, that is, each sidewall of described casing and upper cover are connected by screw or fixture.
Described fiber mesh cloth can be selected has arbitrarily certain flexible fiber mesh cloth for building, but in order to alleviate deadweight better and obtain better tensile strength, and reduce cost of production, preferred glass fibers screen cloth or polypropylene fiber mesh cloth.
For alleviating the utility model deadweight, the sidewall of described casing and upper cover can use PLASTIC LAMINATED, and this fire shield surface has whitewashed cement paste.
The utility model adopts armored concrete slab as base plate, adopts hollow box body as upper component, while effectively controlling own wt, greatly provides efficiency of construction, the reduction of erection time; The utility model can directly be placed on bed die, and reinforced concrete floor can serve as floor and use, without the need to the cast-in-situ concrete again of the below at concrete floor.The utility model is equipped with fiber mesh cloth in concrete floor, uses fiber mesh cloth can alleviate deadweight better and obtain better tensile strength, thus can fall thinner by the thickness of armored concrete slab.

Detailed description of the invention
As Figure 1-3, the cavity building roof component that the utility model provides, comprises reinforced concrete floor 5, hollow box body, and hollow box body is arranged on base plate 5; Be equipped with glass fiber mesh or polypropylene fibre screen cloth in armored concrete slab, the reinforcing bar 6 of reinforced concrete floor stretches out base plate from the sidewall of base plate; The upper cover 4 that hollow box body comprises sidewall 1 and is arranged on sidewall 1, sidewall 1 is connected with fixture 3 firmware, and fixture 3 is connected with base plate 5, is fixed on base plate by sidewall 1 by fixture 3.Casing adopts without bottom surface casing, and adopts split-type structural, and four sidewalls and upper cover make respectively, then by screw or fixture connection.For improving the anti-ability of trampling of casing, be provided with support member 2 in casing, support member 2 is arranged between two parallel sidewalls.For alleviating box weight, the sidewall of casing and upper cover use PLASTIC LAMINATED to make, and cement paste has been whitewashed on the surface of PLASTIC LAMINATED; Also plastic plate etc. can be used.
During construction, first waffle beam reinforcing bar has been tied up, assemble concrete blinding, cavity building roof component 8 is placed in template, the concrete floor of cavity building roof component 8 directly and template contacts, by reinforcing bar that concrete floor stretches out together with waffle beam binding reinforcing bars, Vierendeel girder reinforcing bar is tied up again above cavity building roof component 8, then cast-in-situ concrete operation is carried out, concrete has all been built in surrounding and the top of cavity building roof component 8, in-situ frame beam is formed at the top of cavity building roof component 8, concrete floor forms the bottom surface of cavity building roof together with the bottom of cast-in-place waffle beam.
