Abstract
The utility model discloses an internal mold for cast-in-situ reinforced concrete, which comprises a cylinder, end caps that seal two ends of the cylinder and a positioning device that fixes the cylinder in the reinforced concrete, wherein the cylinder wall consists of a skeleton layer composed of at least one layer of skeleton materials and at least one layer of composite layer, the skeleton layer and the composite layer spliced together, and that a waterproof layer is coated out of the skeleton layer and the composite layer; therefore, the internal mold has better performances and is no longer fragile due to water absorption; besides, the internal mold proves enhanced floatation resistance capacity during construction works, with accurate positioning.
Description
Technical field:
The utility model relates to technical field of buildings, refers to a kind of internal mold that is used for cast-in-situ reinforced concrete especially.
Background technology:
The making of steel bar reinforced hollow concrete roof cast-in-situs is by hollow or solid internal mold (or claim core) 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.
The thin-wall internal-mould that arrives commonly used is made up of pipe and two plugs on the engineering, and internal mold is formed by the cement pouring, thereby, easily produce the phenomenon of internal mold suction in the concrete pouring process, and cause internal mold not antivibration smash, frangible, the cylindrical shell location is inaccurate, easily displacement, and problem such as cylindrical shell anti-floating ability.
The utility model content:
Technical problem to be solved in the utility model is: at above-mentioned the deficiencies in the prior art, a kind of internal mold that is used for cast-in-situ reinforced concrete is provided, in a kind of easy for installation, accurate positioning, the construction anti-floating ability of internal mold by force, do not absorb water, 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 internal mold that is used for cast-in-situ reinforced concrete, it comprises cylindrical shell, the cylindrical shell two ends is connected firmly the plug of sealing and cylindrical shell is fixed in positioner in the steel bar concrete, be characterized in: described barrel wall comprises the casing play that is made of one deck skeleton material at least, and one deck composite bed at least, this composite bed is mutually bonding with casing play, and this casing play and composite bed are coated with waterproofing course outward.
Above-mentioned casing play is mixed, amounts to or surrounds and constituted by one deck skeleton material at least; Composite bed by the mixture of cement, silicon ash intensive, gypsum adjustable solidification agent, flyash and inorganic coagulation material, organic or inorganic mixed material and sand by centrifugal force puddle or compacting or extrude and constitute.And the skeleton material of above-mentioned casing play is gauze wire cloth, plastic wire, fibers material net, pierce tap plastic tape, chemical fibre silk, glass fiber or their mixture.
The deck of above-mentioned positioner 3 is provided with opening 31, as shown in Figures 2 and 3, the deck of this positioner can block reinforcing bar 4 by opening 31, thereby the cylindrical shell 1 that makes internal mold is mounted on the reinforcing bar 4 in the reinforced concrete member by one or several positioners 3, make internal mold easy for installation, accurate positioning; Simultaneously, also internal mold can be bundled on the reinforcing bar 4 with iron wire 5, internal mold can not only accurately be located in structure or member better, more can increase the anti-floating ability of internal mold in the construction, save construction cost.Above-mentioned positioner 3 is fixed on the cylindrical shell 1 or with plug 2 and is wholely set.Be wholely set for plug 2 and positioner 3 shown in the figure.
Above-mentioned cylindrical shell is prefabricated drip molding or the extrusion molding spare that cement prefab, press forming spare, an end have end cap.And the cylindrical shell profile of internal mold can be the cylinder bodily form, shown in Fig. 4 a, the cylindroid bodily form, shown in Fig. 4 b, square top and round bottom shape, shown in Fig. 4 c, cuboid, shown in Fig. 4 d, cone, shown in Fig. 4 e.
Above-mentioned cylindrical shell, plug, positioner are made by the mixture of macromolecular material, metal material, wood materials, Inorganic Non-metallic Materials (as cement, pottery), organic matter and inorganic matter.Can be set to the enclosing cover formula between the cylindrical shell 1 of above-mentioned internal mold and the plug 2, shown in Fig. 5 a or inside-plugging, shown in Fig. 5 b.
The mixture of all or part of filled and process of hollow position in the above-mentioned cylindrical shell, plastic foamed, macromolecular material, metal material, wood materials, Inorganic Non-metallic Materials (as cement, pottery) or organic matter and inorganic matter.
Between above-mentioned cylindrical shell and plug, cylindrical shell and positioner be connected to that cement paste connects, splicing, profile of tooth are connected, riveted joint, thermosol connect, cold cut connects, tongue and groove connects, snap close connects, banding connects.
Thereby, by the waterproofing course that this internal mold is set up outside composite bed and casing play, make the internal mold performance better, can prevent internal mold suction and frangible problem takes place, simultaneously because the band positioner, thereby can make that internal mold is easy for installation, the anti-floating ability of internal mold is strong in the accurate positioning, increase construction.
