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 mould shell (2) is provided with a reinforcing element (5). Thus, the strength and rigidness of the mould shell (2) is greatly improved and the mould shell (2) is not easy to be damaged in carrying and construction processes. The utility model overcomes inefficiency in prior art; correspondingly, the strength and rigidness of floor is improved. At the same time, the floor 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 because the formwork wall thickness in the floor is thinner, easily damaged in carrying and work progress, cause cost to increase, the duration is affected.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 formwork not damaged characteristics in carrying and work progress.
Solution of the present utility model is on the basis of existing technology, formwork is provided with stiffener, like this, the intensity and the rigidity of formwork are strengthened greatly, cracky not in carrying and work progress, thereby the deficiencies in the prior art have been overcome, reached the purpose of this utility model, simultaneously, the intensity of floor and rigidity are corresponding also to be improved, 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 the stiffener on the formwork is reinforcing rib, stiffening rib or support bar or their combination.Like this, formwork can be selected according to design and construction, and with the intensity and the rigidity requirement that satisfy different engineerings, simultaneously, formwork is simple in structure, is convenient to produce, construct.
Feature of the present utility model is that also the stiffening rib on the formwork is parallel, groined type, M shape or other cross shaped head and places vertically or tiltedly put in the formwork cavity.Like this, because stiffening rib has various multi-form and settings, can make things convenient for design and construction unit to select for use.
Feature of the present utility model is that also the support bar on the formwork has one, two, three or many in the formwork cavity, and is hollow stem or solid hopkinson bar.Equally, the quantity of support bar and form can be selected by design and construction unit.
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 the prefabricated plate, and reinforce is reinforcing bar, steel wire, steel mesh reinforcement or gauze wire cloth, 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 in the cavity of formwork heat-insulating and noise-insulating material is arranged, and heat-insulating and noise-insulating material is expanded perlite, expanded vermiculite, foam concrete or foamed plastics.Like this, the heat preservation and soundproof performance of floor is better, is applicable to the occasion of heat preservation and soundproof requirement.
Feature of the present utility model also is in the 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.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.
