The specific embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is described in detail.
As can be seen from Figure 1, cast-in-situ hollow building roof of the present invention, comprise by fixed connecting piece 5 and be fixed in off-loading component between top reinforcement 4 and the lower floor's reinforcing bar 3, concrete is filled between interior off-loading component of whole superstructure and the reinforcing bar and the space between the off-loading component, and described off-loading component is that spherical off-loading monomer 1 and/or ball formula off-loading raft sheet are arranged at interval or closely.
Ball formula off-loading raft sheet of the present invention is for connecting tight or spaced spherical off-loading monomer or forming by the gel rubber material bonding connection by fixture.Fig. 2, Fig. 3 are two kinds of form of structure of fixture, the off-loading raft sheet that forms, be respectively tight arrangement and spaced off-loading raft sheet, shown fixture can be for plastic material, also can be woven into for reinforcing bar and iron wire, the diameter of the circle of this fixture less than or the diameter that is slightly less than the off-loading monomer be advisable.When boning by gel rubber material, this gel rubber material can be for cement etc., in order to reach spaced purpose, and can be by light foam material as intermediate connector.Before construction, can be off-loading raft sheet with the off-loading combination of monomers in advance, be convenient to construction, increase work efficiency.Slit and groove can be filled with cementitious material or light material between combination raft sheet, are more conducive to increase the filler volume, optimize the cross section.
Spherical off-loading monomer of the present invention overall alignment form in superstructure can be provided with as required flexibly, and is for example rectangular evenly distributed or radial evenly distributed, and Fig. 4 is a kind of form of radial arrangement.
Spherical off-loading monomer of the present invention can be spherical shape, oval spherical, oblate spheroid shape spheroid, and Fig. 5, Fig. 6 are structural representation.Spherical off-loading monomer is thin-walled hard hollow body or light foam body or gas cell, as the off-loading monomer of hollow body, can be the combining form of two hemisphere.Spherical off-loading monomer can also be isometrical spheroid or waney spheroid.
Off-loading raft sheet of the present invention, long and wide during when it all more than or equal to 600mm, on combination raft sheet, be provided with sprue gate or pouring basin 2, the form of this sprue gate or pouring basin 2 is formed by spherical off-loading combination of monomers, it is the gap after the spherical off-loading combination of monomers, perhaps be that a spherical off-loading monomer is taken away the gap that the back forms, according to varying in size of the spherical off-loading monomer that uses, can be in different ways.The diverse in function of this sprue gate or pouring basin can be peep hole, air-vent and steam vent, promptly satisfies the engineering construction requirement, is convenient to constructing operation again, and sprue gate or pouring basin 8 be available concrete or light material filling shutoff after cast.On same ball formula off-loading raft sheet, the distance between described sprue gate or the pouring basin satisfies the closely knit requirement of cast smaller or equal to 600mm.
Job practices of the present invention is divided into two big steps:
(1) formwork is laid step:
A side form bed die is set layer reinforcing bar or reinforced mesh on the bed die upper berth, colligation beam, girt strip reinforcing bar earlier; Settle the warm and draft tube liner of pre-buried water power; Lay cushion block then, lay and locate spherical off-loading monomer or ball formula off-loading raft sheet; With iron wire or wire gauze described off-loading component being fixed on lower floor has on the reinforcing bar or the braced structures under the template of reliable drawknot; Lay colligation top reinforcement or reinforced mesh;
The cast-in-situ floor bigger to span, its template should be by the designing requirement arch camber; Pre-buried horizontal pipeline should be arranged between dark Liang Chu or close girt strip according to the caliber size as far as possible; To lay frame plate at any time in the off-loading component installation course, reinforcing bar, off-loading component finished product are protected; Off-loading component lay and reservation work is laid gluten after all finishing, and carry out colligation with the rib steel muscle; Off-loading component is laid and is finished, and after the gluten colligation, directly contacts with off-loading component for preventing gluten, can also place pad in the crosspoint of gluten in length and breadth and be placed between crosspoint and the off-loading component; Measure of anti float is generally established the anti-floating point, and the distance of anti-floating point surely can be in length and breadth every 1500mm-2000mm; In the work progress, the set aside pre-embedded work of installing engineering must intersect parallel carrying out with operations such as laying of reinforcing bar binding, thin-wall box body;
(2) cast step:
Direction in order,, priority laminated pouring vibrated concrete, at first by beam, girt strip reinforcing bar space, sprue gate or pouring basin, the cast lower-layer concrete of vibrating, and observe confirm the lower-layer concrete cast full closely knit after, fill shutoff sprue gate or pouring basin with concrete or light material, then, layer concrete in the cast; Between concrete filling and off-loading member and the reinforcing bar and space between the off-loading component and vibration compacting, wipe off floating to design thickness; Maintenance to intensity reaches designing requirement length of time, form removal, obtains superstructure product of the present invention.
Concrete pouring should be adopted pumping, one-time cast-forming, the cast direction of propulsion along girt strip axis direction or sprue gate or pouring basin carry out by easy stages, pouring out concrete should be even, prevent to pile up too high and the damage off-loading component, utilize the sphere of action of vibration, make concrete get into the off-loading component bottom, guarantee the closely knit of infiltration of lower-layer concrete mortar and girt strip, can carry out shutoff or make concrete fill sprue gate or pouring basin with light material for sprue gate or pouring basin by pouring into a mould layer concrete, form strong braced structures, strengthen the superstructure stressing conditions.
The present invention can pass through existing techniques in realizing without the technical characterictic of describing; certainly; above-mentioned explanation is not to be limitation of the present invention; the present invention also is not limited in above-mentioned giving an example; variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present invention also should belong to protection scope of the present invention.
