Technical field:
The utility model relates to technical field of buildings, refers to a kind of cast-in-situ reinforced concrete internal mold with two-way positioner especially.
Background technology:
The making of steel bar reinforced hollow concrete roof cast-in-situs is by hollow or solid internal mold is set in concrete, and it mainly acts on by the internal mold concrete of finding time, and weight reduction economical with materials consumption improves the stress performance of floor slab structure simultaneously.
A kind of thin-wall internal-mould of using on the engineering, form by pipe and two plugs, in construction, to adopt connector that thin-wall internal-mould is connected with reinforcing bar, or internal mold is fixed with immobilization material, to guarantee that internal mold is not shifted in work progress, solve the anti-floating problem of concrete pouring process middle cylinder body simultaneously, but that it has a cylindrical shell location is inaccurate, easily displacement; The shortcoming of cylindrical shell anti-floating ability.
The utility model content:
Technical problem to be solved in the utility model is: at the deficiencies in the prior art, provide the anti-floating ability of internal mold in a kind of easy for installation, accurate positioning, the construction strong, performance is better with the cast-in-situ reinforced concrete internal mold of positioner.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of cast-in-situ reinforced concrete internal mold with two-way positioner, comprise cylindrical shell, the cylindrical shell two ends are connected firmly the end cap of sealing and cylindrical shell is fixed in positioner in the steel bar concrete, be characterized in that described positioner comprises locating support, the lower end bilateral symmetry of locating support is provided with bearing, and bearing has the outside arc folder mouth of opening.
Also be provided with the liner that is used to finalize the design in the cylindrical shell, the shape of liner is decided according to the shape of cylindrical shell, and the quantity of cylindrical shell liner decides according to the intensity of cylindrical shell, is generally 3-4, and can have according to the desirable strength of cylindrical shell increases or reduce.For reducing material cost, can establish the hole in the liner.Backstay can be added, with secure liner between liner.
Positioner can be one or several, can be installed on the arbitrary position of cylindrical shell, makes internal mold accurate location in structure or member.Positioner can be one-body molded with cylindrical shell, also can install respectively.Positioner both can also can use the top layer reinforcing bar as fixing reinforcing bar with bottom layer of the reinforcing steel as fixing reinforcing bar.The cylindrical shell two ends connect firmly sealing with end cap, and positioner and end cap can form an integral body, promptly produce the end cap of band positioner, also can be positioner to be connected firmly or split is connected on the end cap or on the cylindrical shell.
Cylindrical shell is that one or an above sheet material also surround between the limit by the limit and is formed by connecting, and ways of connecting has welding, splicing, profile of tooth connection, riveted joint, thermosol to connect, tongue and groove connects, snap close connects, banding connects.Cylindrical shell also can press forming spare or is blown out drip molding, or an end has the press forming spare or the extrusion molding spare of end cap.Cylindrical shell can also change the system of circumnutating with steel band or polymer strip and form.The cutting plane shape of cylindrical shell can be circle, triangle, quadrangle, polygon, square top and round bottom shape, ellipse.The shape of the bearing upper end of described positioner is decided according to the cutting plane shape of cylindrical shell.In the cylindrical shell hollow position can all or part of filled and process, the mixture of plastic foamed, macromolecular material, metal material, wood materials, Inorganic Non-metallic Materials such as cement, pottery etc. or organic matter and inorganic matter.
Cylindrical shell and end cap can be that splicing, welding, profile of tooth are connected, riveted joint, thermosol connect, cold cut connects, tongue and groove connects, snap close connects, banding connects.
Cylindrical shell, liner, end cap, positioning support, backstay can be made by macromolecular material, metal material, wood materials, Inorganic Non-metallic Materials (as cement, pottery) or the mixture of organic matter and inorganic matter.
Compared with prior art, the utility model has the advantages that: positioner is set; thin-wall internal-mould links to each other with reinforcing bar in the reinforced concrete member by one or several positioners; cylindrical shell is fixed in above the longitudinal reinforcement by the outside mounting and positioning device of opening; both prevented the motion of cylindrical shell transverse horizontal; can prevent the cylindrical shell come-up again, utilize the transverse reinforcement at cylindrical shell two ends, prevent that the cylindrical shell vertical equity from moving by thin-wall internal-mould end cap or other position at cast-in-situ reinforced concrete.Thereby make internal mold easy for installation, accurate positioning, the anti-floating ability of internal mold is strong in the construction, saves construction cost simultaneously.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a positioner embodiment front view of the present utility model.
Fig. 3 is that positioner shown in Figure 2 connects cylindrical shell and the building reinforcing bar is implemented schematic diagram.
The specific embodiment:
As shown in Figure 1, in the present embodiment, internal mold is made up of cylindrical shell 1, positioner 2, end cap 3 and liner 4.
As shown in Figure 2, positioner 2 comprises locating support 21, and the lower end bilateral symmetry of locating support 21 is provided with two bearings 22, and the cave inward opening of camber folder mouthful 23, two arcs folder mouthfuls 23 of bearing 22 is all outside.Locating support 21 is a hollow sting, and internal mold can be fastened in the support hollow position, and the shape of locating support upper end 24 can be according to the shape on the top, cross section of internal mold cylindrical shell 1 and decided.In the present embodiment, the cross section of cylindrical shell 1 is circular, and therefore, locating support upper end 24 is semicircle.Recessed in bottom 25 mediads of locating support, the lower end of cylindrical shell 1 is fastened in the bottom 25 inboard centre of locating support 21.
