Description
(1) technical field
The utility model relates to a kind of rib of slab combined reinforced bar concrete cassette ceiling.
(2) background technology
The most of precast hollow slab that adopts of the building of brick mix structure and frame construction is as floor structure at present, it is fast that this floor structure has speed of application, advantages such as cost is low, but owing to firmly do not link between adjacent two precast hollow slabs, only use cement mortar blind, thereby not only globality is poor, is unfavorable for antidetonation, and slit cracking, infiltration often appear, put to no little inconvenience and psychological pressure to resident family.In order to address the above problem, a lot of building have adopted the method for Cast-in-place concrete floor (hollow, solid).Though the Cast-in-place concrete floor has solved antidetonation and problems of crack, when construction, to use a large amount of templates, like this, not only increased expense, and the speed of application that slowed down, prolonged the duration.The patent No. is ZL00203695.9's " combination concrete hidden rib floor structure " utility model patent, it is made up of prefabricated plate, formwork, dark rib, upper plate, each prefabricated plate is horizontal positioned at interval, is fixed with formwork on prefabricated plate, is provided with dark rib between contiguous prefabricated thin plate or the formwork, upper plate covers on the formwork, and connect as one with dark rib, this kind floor structure no longer needs to use template in a large number, has accelerated speed of application, shorten the duration, thereby reduced cost.But because formwork is fixed on the prefabricated plate, does not relate to concrete fixed form and fixture, thereby bring great inconvenience, influence normal construction to construction.Therefore, develop a kind of novel rib of slab combined reinforced bar concrete cassette ceiling for being badly in need of.
(3) utility model content
The purpose of this utility model is to provide a kind of rib of slab combined reinforced bar concrete cassette ceiling, have easy construction, easily, characteristics efficiently.
Solution of the present utility model is on the basis of existing technology, be useful on formwork at formwork and the two correspondence position of prefabricated plate and be fixed in fixed connecting piece on the prefabricated plate, fixed connecting piece can be fixed on formwork and the prefabricated plate by reserving mode pre-buried or prefabricated or that adhere to.Like this, formwork can be fixed on the prefabricated plate easily by fixedly connected thing, makes construction become easy and quick, accelerates speed of application, reduces cost, and enhances productivity.In addition, floor also has globality and characteristics such as shock resistance is good, do not seep water, need not a large amount of templates, speed of application is fast.
Feature of the present utility model is that also fixed connecting piece is pre-buried weldment, cutting ferrule, perforated bolt, screw, iron wire or glued cured layer.Like this, owing to there are various fixed connecting pieces selective, make to produce to become simple, it is easy, quick that construction becomes, and made things convenient for design, production, construction, reduced cost, improved benefit.
Feature of the present utility model also is to be useful on the location thing that formwork connects the location on the prefabricated plate, and the location thing is locating piece, positioning strip, posting, locating slot, locating ring, reference column, fastening screw hole or fixed connecting piece.Like this, owing to be useful on the location thing that formwork connects the location on prefabricated plate, therefore, make construction be more prone to, speed of application is faster.
Feature of the present utility model is that also formwork is the open shutting of inside or outward flanging.Like this, for open shutting, because inside or outward flanging are arranged, the position that can protect formwork to contact with prefabricated plate is preferably avoided destroying or falling the limit, simultaneously, also can play the location.
Feature of the present utility model is that also the external surface of formwork is waveform, zigzag, plucking shape, impression rough external surface.Like this,, further improve the intensity and the rigidity of floor because the external surface of formwork is a rough surface, thereby can increase the adhesion stress between formwork and the Cast-in-place concrete, and overall performance.
Feature of the present utility model is that also stiffener is arranged on the formwork, and stiffener is reinforcing rib, stiffening rib or support bar.Like this, the intensity and the rigidity of formwork are strengthened greatly, cracky not in carrying and work progress, and the formwork that various stiffener forms are provided simultaneously is for the selection of design and construction unit, to satisfy the needs of different engineerings.
Feature of the present utility model is that also reinforcing rib is arranged on the prefabricated plate.Can improve the intensity and the rigidity of prefabricated plate like this, but the thickness of attenuate prefabricated plate correspondingly, and convenient carrying, construction reduce cost.
Feature of the present utility model is that also reinforce is arranged in the prefabricated plate, and reinforce is reinforcing bar, steel wire, steel mesh reinforcement, gauze wire cloth, fiber or fleece, the muscle of revealing is perhaps arranged simultaneously or reveal net or dew muscle and dew net.Like this, the intensity and the rigidity of prefabricated plate further improve, and the thickness of prefabricated plate can further reduce, and cost can further reduce, and it is more convenient to carry, construct.If prefabricated plate reveals muscle simultaneously in addition or reveals net, and is then better with the bonding of Cast-in-place concrete, more difficult between prefabricated plate and cast in place reinforced bar concrete hidden rib or produce micro-crack between the prefabricated plate, globality, the shock resistance of floor are stronger.
Feature of the present utility model is that also the edge of prefabricated plate is step, hypotenuse shape, profile of tooth, waveform, broken line shape or shaped form.Like this, with the adhesion stress that further strengthens between prefabricated plate and concrete or the cement paste, perhaps the mutual inlay resultant force between the prefabricated plate with the possibility of further minimizing floor cracking, thereby improves floor globality, shock resistance.
Feature of the present utility model also is to reveal muscle or reveals net or reveal muscle and reveal one side from the upper surface of prefabricated plate along the edge of net, two limits, three limits or upwards or oblique stretching out all around.Like this, owing to reveal muscle or reveal net from the upper surface of prefabricated plate along the edge upwards or oblique stretching out, thereby prefabricated plate can the row of being close to split layout when arranging, and need not at dark flank position support shuttering, with further reduction expense, and the quickening speed of application.And the fine gap between the prefabricated plate will be filled up by cement paste under vibrating, thereby eliminates the slit between the prefabricated plate.
Feature of the present utility model is that also glued cured layer is single-point tack coat or multiple spot tack coat or large tracts of land tack coat.Like this, single-point, multiple spot or large tracts of land tack coat can be selected flexibly according to the size of the bond of glued cured layer by unit in charge of construction.
Feature of the present utility model also is in dark rib reinforcing bar is arranged, and reinforcing bar is prestressed reinforcement, prestress wire, cold-rolled forming section, channel-section steel or i shaped steel, and reinforcing bar is implied in the dark rib or with dark rib soffit and flushes.Like this, in dark rib,, can improve its supporting capacity effectively, prevent the generation in crack, and be specially adapted to the floor slab in space structure of large bay, large span because reinforcing bar is arranged.
