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 the dark rib in the floor is in order to satisfy the requirement of rigidity, often size is bigger, and like this, own wt is bigger on the one hand for dark rib, and high material consumption causes construction cost to increase on the other hand.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, has in light weight, characteristics such as material consumption is little, cost is low, intensity and rigidity height.
Solution of the present utility model is on the basis of existing technology, the boss mould that at least more than one is arranged at least one side of formwork, the cast in place reinforced bar concrete hidden rib that constitutes between the adjacent formwork is the dark rib of lightweight, and the dark rib of lightweight is hollow dark rib or empty stomach dark rib of shape or the dark rib of light solid.Like this, because dark rib is the dark rib of lightweight, thereby weight is lighter, the corresponding minimizing of material consumption, construction cost reduces, and can satisfy the requirement of intensity and rigidity simultaneously, the deficiencies in the prior art have been overcome, reached the purpose of this utility model, characteristics such as in addition, floor also has globality and 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 the boss of formwork has prefabricated units between touching, and prefabricated units are post or bar or plate, and prefabricated post or bar or plate are to be placed vertically or tiltedly put.Like this, between formwork, particularly, adopt prefabricated post or bar etc., the concrete quality is guaranteed, thereby guarantees the intensity and the rigidity of the dark rib of lightweight, form the dark rib of prefabricated and cast-in-place truss-like in the vibrate place of moulding of the narrow inconvenience that the boss mould is arranged.
Feature of the present utility model also is on adjacent two sides of formwork the boss mould is arranged.Like this, when construction, can carry out the layout between the formwork convenient and reasonablely, raise the efficiency, the reduction of erection time, reduce cost.
Feature of the present utility model is that also reinforcing rib is arranged on 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 prefabricated plate, reinforce is reinforcing bar, steel wire, steel mesh reinforcement, gauze wire cloth, fleece or unidirectional, two-way or random in fibre, 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 be reinforcing bar, steel wire, steel mesh reinforcement or gauze wire cloth one side, two limits, three limits from the upper surface of prefabricated plate along the edge or all around upwards or oblique being extended with reveal muscle or reveal net or reveal muscle and reveal net.Like this, protrude upward along the edge from the upper surface of prefabricated plate, thereby prefabricated plate can the row of being close to split layout when arranging, and need not at dark flank position support shuttering owing to reveal muscle or reveal net, with further reduction expense, 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 the external surface of formwork is waveform, zigzag, plucking shape or impression rough 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 also is at formwork stiffener is arranged, 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 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 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.
