Abstract
A board-rib combined steel reinforced concrete hollow floor comprises a prefabricated sheet (1), a mould shell (2), a hidden rib (3), and an upper plate (4). The prefabricated sheets (1) are horizontally arranged alternatively; the mould shell (2) is fixed on the prefabricated sheets (1); the hidden rib (3) is arranged between adjacent prefabricated sheets (1) or between mould shells (2); the upper plate (4) is covered on the mould shell (2) and is connected with the hidden rib (3) to be an integrated body. The utility model is characterized in that the upper surface of the mould shell (2) is provided with a groove (5); correspondingly, the lower part of the upper plate (4) forms a scene cast hidden secondary rib (6). Thus, the hidden rib (3) and the scene cast hidden secondary rib (6) on the lower part of the upper plate (4) form a mutually crossing primary and secondary hidden close rib structure, which greatly improves the strength and rigidness of floor, and in particularly improves the strength and rigidness of the upper plate; the utility model is characterized in that the floor has no crack or no damage with the influence of impact load or heavy materials. At the same time, the utility model also has the characteristics of good integrity and seismic resistance, no water seepage, no need for substantial templates, large construction speed and so on.
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 under the thin situation of upper plate thickness of slab, very easily under the effect of impact load or weight, produce excessive deformation, crackle, even destroy, influence the normal use of floor.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 flooring flawless, non-destructive characteristics under the effect of impact load or weight.
Solution of the present utility model is on the basis of existing technology, is provided with groove at the upper surface of formwork, correspondingly forms the Cast-in-place concrete hidden sub-rib in the bottom of upper plate.Like this, the Cast-in-place concrete hidden sub-rib of cast-in-place concrete hidden rib and upper plate bottom forms the dark close rib structure of staggered primary and secondary mutually, thereby improve the intensity and the rigidity of floor greatly, particularly improve the intensity and the rigidity of upper plate, have under impact load or weight effect, flooring flawless, non-destructive characteristics, thus reached the purpose of this utility model.Simultaneously, also have globality and shock resistance good, do not seep water, need not characteristics such as a large amount of templates, speed of application are fast.
Feature of the present utility model is that also the Cast-in-place concrete hidden sub-rib of upper plate has one, two, three or many, and that two above hidden sub-ribs are is parallel, quadrature or diagonal cross are arranged.Like this, can select, to satisfy the requirement of different engineerings according to design and construction.Wherein, be arranged in parallel with the Cast-in-place concrete hidden sub-rib or intersecting parallels is arranged better.
Feature of the present utility model also is in the Cast-in-place concrete hidden sub-rib of upper plate reinforce is arranged, and reinforce is reinforcing bar, steel wire, steel mesh reinforcement, gauze wire cloth, fleece or fibre.Like this, behind the adding reinforce, the intensity and the rigidity of upper plate are further strengthened in cast-in-place hidden sub-rib, and supporting capacity and shock resistance further improve.
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 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 prefabricated plate, reinforce is reinforcing bar, steel wire, steel mesh reinforcement, gauze wire cloth, fleece or 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 are further strengthened, thereby the thickness of prefabricated plate can further reduce, and cost further reduces, and carrying, construction are more convenient.If prefabricated plate reveals muscle simultaneously in addition or reveals net, and is then better with the bonding of Cast-in-place concrete, more difficultly between prefabricated plate and cast in place reinforced bar concrete hidden rib, produce micro-crack, 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 is also that the relevant position on formwork and prefabricated plate is reserved with or is embedded with and is used for formwork and is fixed in fixture on the prefabricated plate that fixture is pre-buried weldment, cutting ferrule, bolt, screw, iron wire.Like this, in work progress, can easily formwork be fixed on the prefabricated plate,, accelerate speed of application to guarantee construction quality.
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-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.
