The present invention directly adopts the fabricated polystyrene foam board as the non-detachable formwork of the reinforced concrete ribbed floor that is poured on site. After the pouring is completed, it is not dismantled and can be used for one time. The floor structure is small in height and light in weight, and has the advantages of convenient construction It has the advantages of simplicity and fast construction speed, and at the same time has good energy-saving effects such as sound insulation and thermal insulation. It can be used for floor slabs of various industrial and civil building structures such as masonry, frame structure, and frame-shear wall structure.
Description
Technical field
The present invention relates to buildings in general structure field, especially relate to a kind of cast-in-place reinforced concrete embedded composite multi-ribbed energy-saving floor structure system, be applicable to construction work building energy conservation has higher requirements, floor height has strict restriction.
Background technology
Under the present level of economic development and Building technology condition, what generally use in the construction work is single, double to girt strip beam building roof structure system, the superstructure cost of this structural system is low, power transmission is clear and definite, easy to make, but the building cover structure height that comprises secondary beam is higher, building that furred ceiling finishing arranged particularly office building has often been wasted the space of secondary beam bottom at the bottom of the plate, has influenced effective utilization of architectural space to a great extent.In addition, traditional one-way slabs girt strip superstructure and two-way slab girt strip superstructure are because plate hight is less, and floor self thermal transmittance is bigger, be difficult to effectively stop the heat transmission between the different spaces,, greatly increased building energy consumption and use cost for creating suitable interior temperature and keeping temperature constant, cause unnecessary waste, simultaneously, less FFL also causes defening effect relatively poor, can not satisfy country to the building energy conservation environmental protection requirement.Therefore, how developing a kind of secondary beam that can reduce takes up room, increasing space availability ratio avoids waste, can effectively utilize superstructure to have its energy-saving effect of spatial development again, and do not increase the novel building cover structure system of construction investment cost and construction difficulty, become current builing industry problem demanding prompt solution.
Summary of the invention
The objective of the invention is at using the defective that floor system can not effectively satisfy energy-conservation requirement and make full use of architectural space in the present construction work always, a kind of building cover structure system that energy-conservation requirement, space effectively utilized and increased not significantly cost of construction that satisfies is provided, a kind of cast-in-place reinforced concrete embedded composite multi-ribbed energy-saving floor structure system promptly is provided, has made it to satisfy the each side requirement.
A kind of cast-in-place reinforced concrete embedded composite multi-ribbed energy-saving floor structure system, comprise the close rib building roof plate body, described close rib building roof plate body is provided with the girt strip that the well word is arranged, be provided with steel bar stress in the girt strip, also be provided with steel bar stress in the close rib building roof plate body, the square space between the girt strip embeds the lightweight thermal baffle core.
Described lightweight thermal baffle core is fire-retardant self-extinguishing type polystyrene foam plate.
Described steel bar stress is common hot-rolled reinforced bar, cold rolled reinforcing bar or hard drawn wire reinforcement.
The used cast-in-situ concrete material of close rib building roof plate body and girt strip is general concrete or light weight aggregate concrete
The building method of this reinforced concrete embedded composite multi-ribbed energy-saving floor structure system carries out at the construction field (site), may further comprise the steps: at first, prop up the exterior sheathing of good floor, in template, place the steel bar stress of girt strip, place the lightweight thermal baffle core according to set specification, at last, cast-in-site steel concrete and maintenance are shaped to reinforced concrete embedded composite multi-ribbed energy-saving floor structure system.
The reinforced concrete embedded composite multi-ribbed energy-saving floor structure system of the present invention has utilized the close rib building roof technology, has reduced the low problem of space availability ratio that causes because of time depth of beam in the architectural space.Simultaneously, make full use of the girt strip space of close rib building roof, embed fire-retardant self-extinguishing type polystyrene foam plate, neither take unnecessary space, can bring into play the low advantage of polystyrene foam plate thermal transmittance again, the effectively heat transmission between the control different spaces for the temperature that keeps separate space, reduces building energy consumption and use cost and plays a good role.

The specific embodiment
As shown in Figure 1, the cast-in-place reinforced concrete embedded composite multi-ribbed energy-saving floor structure system of the present invention, comprise close rib building roof plate body 1, this close rib building roof plate body 1 is provided with the girt strip 2 that the well word is arranged, be provided with steel bar stress 5 in close rib building roof plate body 1, the square space between girt strip 2 is embedded with lightweight thermal baffle core 4.The area of the steel bar stress 5 in the close rib building roof plate body 1 needs according to the span of suffered load size of floor and floor and strides several situations and determine by calculating.The girt strip 2 used cast-in-situ concrete materials that close rib building roof plate body 1 and well word are arranged are general concrete or light weight aggregate concrete, require to determine the thickness of this embedded compound close rib energy-saving floor under the prerequisite that satisfies stressed, distortion, crashproof, anti-fire.The lightweight thermal baffle core 4 of 2 embeddings of girt strip adopts fire-retardant self-extinguishing type polystyrene foam plate.The material of the reinforcing bar in girt strip 2 and the close rib building roof plate body 1, employing be common hot-rolled reinforced bar, cold rolled reinforcing bar or hard drawn wire reinforcement.
The building method of realizing the cast-in-place reinforced concrete embedded composite multi-ribbed energy-saving floor structure system of the present invention carries out at the construction field (site).Referring to Fig. 1, during building operations, this ribbed slab floor plate body 1 connects as one with post 3, and the joint of the top of post 3 and close rib building roof plate body 1 is typically provided with concrete capital reinforcing rib.During construction, in close rib building roof plate body 1, also to arrange the pipeline that each is professional, not shown.Therefore, this cast-in-place reinforced concrete embedded composite multi-ribbed energy-saving floor structure system building method is taken into account these factors simultaneously, may further comprise the steps: at first, prop up the exterior sheathing of good floor, in template, place the steel bar stress in the girt strip, place fire-retardant self-extinguishing type polystyrene foam plate as the lightweight thermal baffle core according to set specification, last, cast-in-site steel concrete and maintenance are shaped to reinforced concrete embedded composite multi-ribbed energy-saving floor structure system.Formed new structure system of this technology and construction technology have the construction simple and fast, characteristics such as cost is low, energy-saving effect is good.
Cast-in-place reinforced concrete embedded composite multi-ribbed energy-saving floor structure system of the present invention and building method, can solve floor system at present commonly used and can not effectively satisfy energy-conserving and environment-protective requirement and the higher defective that can not make full use of architectural space of dimension girder construction height, and increase the building cover structure system that cost of construction can be used for all types of industries such as masonry, frame construction, frame shear wall structure and civilian construction structure not significantly.
