Abstract
A cast-in-situs hollow floor slab with assembled shed board as formwork relates to a floor slab of novel structure. The prior floor slab has the drawback of large self weight, much material consumption, high cost and complex sequence. The utility model comprises a shed board (1), a shell (2) arranged on upside of the shed board (1) and a reinforced steel bar (3) arranged between neighbored shell (2), wherein, the shell (2) and the steel bar (3) are fixed with the shed board (1) by the casting concrete (4). The mould of the utility model is the shed board without turnover utilization. The shed board is used as the mould without large hang filling and transport device, thereby reducing working sequence, saving labor and financial fund and improving construction speed. The shell in the floor slab is a hollow construction. A 'T' shape bent member formed by the concrete and the steel bar has the large stress bearing intensity, light self weight, little material consumption, low cost, which is easy to satisfy all requirements of anti-shock, fire-proof and sound-proof and easy to construct, thereby improving working efficiency. The decorative effect of the building is beautiful and easy to popularize.
Description
Technical field: the utility model relates to a kind of floor with new structure.
Background technology: reinforced concrete floor is main and the most widely used floor slab structure in the Contemporary Architecture engineering, adopt the floor of economical rationality structure and easy manufacture method, to satisfying the function of use requirement of people to building, reduce engineering cost, quicken construction speed, guarantee fire prevention, antidetonation and the sound insulation value of building, important meaning is all arranged.In the existing reinforced concrete floor structure, various ways such as prefabricated assembling floor, ribbed slab floor, prestressing without bondn floor are arranged.Advantages such as wherein prefabricated assembled floor in civilian construction, mostly is the bar shaped precast hollow slab, and batch production degree height is arranged, and speed of application is fast, but the floor globality is bad, and shock resistance is poor, and the slab-joint cracking problem can not get effective solution as common quality defect throughout the year.The most widely used at present common solid floor, lower to the construction technology conditional request, but it exists consume material many, from great shortcoming.Floor stress performance with ribbing is more reasonable than solid flat board, can save material, alleviates deadweight, but because the form technology complexity, so be difficult to be widely adopted.The prestressing without bondn floor is to make on common cast-in-place solid floor basis, applying tension stress after solid floor intensity reaches setting forms, it can reduce the amount of deflection of floor, form very big span space, but this type of floor is except that having common solid floor from great shortcoming, and its consumptive material is more, and technology is more complicated, speed of application is slower, and fireproof performance is bad." cast-in-situ concrete (GBF high-strength thin-wall pipe) arch without beam " technology by Mr.'s Qiu Zeyou invention has overcome the shortcoming of above-mentioned existing floor preferably in recent years, its deadweight is lighter, consumptive material is less, ceiling does not have beam, no cap, comprehensive cost decreases in theory, but this technology difficulty of construction is bigger, and still need the big flat die plate of opening, and formwork in construction, the workload of form removal is still very big, ceiling need manually be done the processing of plastering after the form removal, because of the GBF high-strength thin-wall pipe that requires in the technology core as patented technology brings a high price, cause the cost of floor still high, again so be difficult to apply.
The utility model content: the purpose of this utility model is to provide a kind of intensity height, from the floor of heavy and light, it comprises refractory slab 1, above described refractory slab 1, be provided with the housing 2 of hollow cavity 2-1, be provided with reinforcing bar 3 on the refractory slab between the adjacent housings 21, described housing 2 and reinforcing bar 3 all carry out fixing with refractory slab 1 by fluid concrete 4.Template in the utility model is a kind of refractory slab that need not have enough to meet the need use, use as template with refractory slab, it need not large-scale lifting and haulage device, reduced operation, manpower and materials have been saved, can be directly with the pattern of making towards indoor refractory slab face with beautiful decorative pattern, ceiling need not be plastered, so improved the office operation condition widely, accelerated speed of application simultaneously, housing in the floor is hollow structure, and the T shape flexural member that forms between the housing of adjacent hollow structure is subjected to force intensity big, and it is from heavy and light, consumptive material is few, cost is low, can satisfy antidetonation, fire prevention, the index of every requirement such as sound insulation, it is easy to construction, has greatly improved efficiency of construction, is beneficial to and applies.
Description of drawings: Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the A-A sectional view of Fig. 1, and Fig. 3 is the structural representation of the specific embodiment two, and Fig. 4 is the A-A sectional view of Fig. 3.
The specific embodiment one: with reference to Fig. 1, Fig. 2, present embodiment comprises refractory slab 1, above refractory slab 1, be provided with the housing 2 of hollow cavity 2-1, housing 2 can be made with the waste and scrap that reclaims, as regenerated plastics, the upper bottom surface of described housing 2 is a waveform, corrugated upper bottom surface can improve the intensity of housing 2, and can place pipeline along groove, the longitudinal section of housing 2 is an inverted U-shaped, any one longitudinal section of present embodiment middle shell 2 is inverted U-shaped, is provided with reinforcing bar 3 on the refractory slab between the adjacent housings 21, and described reinforcing bar 3 is horizontal and vertical two-way simultaneous setting.Described housing 2 and reinforcing bar 3 all carry out fixing with refractory slab 1 by fluid concrete 4, and after concrete 4 cast, concrete and reinforcing bar can form two-way T shape flexural member, and there is the intensity height in it, from heavy and light, advantage that consumptive material is few.
The specific embodiment two: with reference to Fig. 3 and Fig. 4, present embodiment is provided with rib 5 on refractory slab 1, rib 5 is a plurality of, a plurality of ribs 5 are closely fixing with refractory slab 1, can in the processing refractory slab, just rib 5 be cast directly over refractory slab 1, rib 5 plays the effect that improves refractory slab intensity, housing 2 is three to wear the flute profile of plate, thereby the riser edge card of housing 2 is made housing 2 crosswise fixed at the edge of opening of rib 5, also be connected with on the described refractory slab 1 and hang muscle 6, the described muscle 6 that hangs is reinforcing bar, one termination of hanging muscle 6 is embedded near the rib 5 in the refractory slab 1, and another termination of hanging muscle 6 is arranged on outside the hollow cavity, and the workman easy for installation who hangs muscle guides and supports refractory slab and lays, simultaneously because hanging muscle and promptly can being embedded in the middle of the concrete of exposing after the fluid concrete makes that refractory slab is unlikely to come off.
