Description
Technical field
The utility model relates to concrete hollow floor cast-in-site building unit, relates in particular to a kind of compound casing of filling concrete of light solid.
The utility model also relates to the supporting installed part that is used for fixing above-mentioned filling concrete inorganic compounding casing.
Background technology
In order to alleviate the dead load of concrete building cover plate better, the deflection deformation of control floor, and saving reinforcing bar, reduce comprehensive cost, to meet low-carbon (LC), energy-saving and environmental protection requirement, the floor design cast-in-place concrete hollow floor slab technology that adopt more, the one-tenth pole that it adopted, or the title internal mold, being divided into two classes, a class is a thin-wall hollow pipe; One class is cylindrical shell, the block of light solid, for example the disclosed a kind of cast-in-situ concrete hollow floor filling rod of ZL200720030993.2.
As further improvement, the hollow building cover that CN101812884A provides a kind of surface to be difficult for breaking infiltration is filled and is used compound casing, it comprises the light solid casing, and the hard shell that is coated on the light solid box outer surface, described light solid casing has at least four seamed edges that are parallel to each other to fall into fillet or oblique angle, feasible one side can make things convenient for casing construction colligation, is difficult for because of colligation makes the breakage of casing seamed edge, and blanking is smooth and easy when making concrete pouring simultaneously.But, such casing finished product processed complex, cost of labor is bigger, and when the on-the-spot use of cast, the seamed edge of two chamferings on its top is easily trampled damaged because of the construction workman.
Simultaneously, when the compound casing of stating light solid in the use carried out the concrete hollow floor cast-in-site, normally the compound casing of filling concrete being embarked on journey was laid between the bilevel reinforcing bar of floor, tied up surfacing steel bar after, fluid concrete.In casting process, because the compound casing deadweight of the filling concrete that is adopted is light, can produce floating moving, influence the floor casting quality.Therefore, must when simplifying product processing, solve the problem that installs and fixes of the compound casing of lightweight.And existing fixed card frame is only applicable to the fixed installation of cylindrical shape noggin piece.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, compound casing of the easy filling concrete of processing.
The compound casing of filling concrete described in the utility model comprises the light solid casing, and the hard shell that is coated on the light solid box outer surface; Two seamed edges that are parallel to each other on described light solid casing top are the right angle, and two seamed edges that are parallel to each other of its underpart correspondence fall bevel or fillet.
Because the utility model only needs two seamed edges that are parallel to each other of lower box are fallen bevel or fillet, the product processing capacity reduces; Simultaneously,, increased casing top stress surface, can effectively avoid trampling damaged because of the construction workman in that cast is on-the-spot because of the seamed edge on casing top is the right angle.Secondly, when its underpart edge chamfering can keep watering material simultaneously blanking smooth and easy, guarantee that bottom half is concrete closely knit.
The utility model can offer the cast-in-place material guide hole of perforation on the light solid casing, attach fiber mesh layer or plastic sheet in cast-in-place material guide hole, to strengthen cast-in-place material guide hole place intensity, avoids product breakage.Certainly, also can increase the cement paste thickness of cast-in-place guide hole wall, to strengthen intensity.
Scheme as an alternative, for strengthening cast-in-place material guide hole place intensity, cast-in-place material guide hole upper port can be provided with local reinforcement, and this local reinforcement is the suitable straight tube of an external diameter and cast-in-place material guide hole aperture, and the upper port of straight tube has flange.
The utility model also provides a kind of installed part that is used for fixing the compound casing of above-mentioned filling concrete, comprises that can be fixed on the cast-in-site reinforced frame is draw piece, and some right angle with two mutual vertical card faces is protected card; The right angle portion that described right angle protects card is provided with groove; Described is that draw piece is fastened from the groove process.Scheme also can be respectively arranged with at least two fins on described two vertical card faces as an alternative; Described is that draw piece is fastened from process between the fin.
In installed part, use the right angle to protect card, can avoid top seamed edge breakage when being tied of compound casing; The right angle protects the right angle portion groove or the fin setting of card, and can avoid is that draw piece protects card and goes up slippage and open from the right angle, influences casing and fixes.
As supporting use, described installed part also comprises a bottom poppet; Described bottom poppet is hollow pad pipe or the pad stool that sets up or be fixed on the cast-in-site reinforced frame.
During actual the use, two or more bottom poppets are placed respectively according to compound casing bottom size.As use hollow pad pipe, then can directly the pad pipe be placed on the floor bar frame; As use the pad stool, can directly place or be fixed on the template.To be draw piece, and, pass the bottom poppet in advance and be fixed on the reinforced frame, then the compound casing of filling concrete will be positioned on the poppet of bottom as iron wire etc.; Establish at the top of compound casing seamed edge card and some the right angle to be protected card, being draw piece protects between the right angle portion groove of card or the fin through fastening from the right angle.
Installed part described in the utility model is simple in structure, makes simple and easyly, is applicable to the fixing of all kinds of cassette ceiling filling concrete casings, improves the on-the-spot cast work efficiency of filling of concrete.
