Description
Technical field
The utility model relates to construction engineering technical field, and particularly floor member technical field, specifically refers to oneCavity body and cassette ceiling.
Background technology
In the field of concrete structure, cassette ceiling is current more advanced a kind of member now. But due to useIn the complexity of a great variety of the hollow body of cassette ceiling, and effect is different, and cassette ceiling is in building trade or with cast-in-place sideIt is many that case is carried out construction, does not also form a kind of industrialized production system and can be produced and cater in batches real estate industryThe growth requirement of changing. Hollow body is concrete lightweight substitute, is generally divided into obturator and cavity body. Cavity body is generally ballThe model of shape or rectangle. The arrangement and method for construction of cassette ceiling is mainly the cast-in-place pattern in domain:
1) set up slab form;
2) laid bottom steel rib or bar-mat reinforcement;
3) cast bottom concrete;
4) after solidifying, bottom concrete places hollow body and top rebars bar or bar-mat reinforcement;
5) complete cast concrete to flooring height.
The floor of this arrangement and method for construction needs twice cast, and has increased and place the operation of hollow body and while making site operationBetween and cost increase on foot, and therefore lowered the feasibility of cassette ceiling in Application in Building.
Particularly, the major defect of existing cassette ceiling technology has following listed several:
1) arrangement and method for construction of cassette ceiling need to carry out at scene, domain. Need scene to order template, need twice cast, needWant on-the-spot degree chi and place hollow body, wasting time and energy, cost is high, also causes claim for eot.
2) existing cavity body is designed with the problem of floating in not solidified concrete, and general solution is additionalSteel reinforcement cage fixes or is pressing cavity body to concrete setting with weight. Prior art at this to increase the solution of permanent steel consumptive materialCertainly not environmental protection of scheme is uneconomical, and another program need expend too much production time and space, has hindered cassette ceiling flowing water linemanThe development that industryization is produced.
3) another shortcoming of existing cavity body is cannot extract after the concrete floor after solidifying is combined. This is establishedMeter defect is that construction party has at the scene and need to change or adjust time, have brought great difficulty. Even because little change also needsTo destroy rear restructuring in type floor and cavity body. This type of reparation is difficult to guarantee reparation in difficult job siteQuality. Therefore often cause floor to have the problem of out-of-flatness and seepage.
4) existing cavity body also has the defect that causes cavity internal water accumulation because of steam vent in the design shortcoming at top. This lacksFall into the little floor seepage that causes, greatly cause the xoncrete structure that ice expansion (freeze-thawaction) causes to be determinedSplit and peel off, and causing human life and property loss.
5) the prefabricated scheme of existing cassette ceiling can only be half prefabricated. Top rebars and concrete also need be in domain with scenesMoulding by casting. Cast-in-site need to expend a large amount of manpowers and material resources, and certainly leads to a large amount of construction wastes, causes environmental pollution.
Therefore, need to provide a kind of cavity body, it can not float in not solidified concrete, with solidify after concreteBase plate in conjunction with can extract later, can not cause cavity internal water accumulation, and safety economy environmental protection adopts this cavity body can precast hollow buildingThe member that hardens, thus without cast-in-site cassette ceiling, improve prefabricated rate, time saving and energy saving, reduce costs the reduction of erection time.

The supporting structure 60 of described cassette ceiling 20 refers to described cassette ceiling 20 placement locations building aroundMember, such as body of wall, crossbeam, pillar etc.
Existing cassette ceiling is single load bearing type cassette ceiling, and cassette ceiling of the present utility model 20 is two-way being subject toPower type cassette ceiling, does not have concrete between surrounding side, concrete roof 50 and the concrete floor 30 of cassette ceiling 20, because ofThis, the surrounding side of cassette ceiling 20 all can be laid connectivity reinforcing bar 70. Shown in Figure 12, in one of the present utility modelIn constructing structure, between cassette ceiling 20 and cassette ceiling 20, on concrete floor 30, lay connectivity reinforcing bar 70, avoidThe constructional difficulties problem that protruding type reinforcing bar connects. Shown in Figure 13, in another kind of constructing structure of the present utility model, skyBetween heart floor 20 and supporting structure 60 (here specifically spandrel girder), lay connectivity reinforcing bar 70. It is shown in Figure 14,In another kind of constructing structure of the present utility model, cassette ceiling 20 and supporting structure 60 (load bearing wall or hold specifically hereHeavy post) between lay connectivity reinforcing bar 70.
In cassette ceiling 20, can place steel bar girder, make the cassette ceiling 20 of twice casting complete have compound action,And strengthen the anti-bending strength of cassette ceiling 20.
Cavity body 10 of the present utility model and concrete floor 30 can be in the in-built spellings of prefabricated factory, also can be at the construction field (site)Completing dress spells. The convenient transport of removable design and the construction of cavity body 10 are changed.
Adopt the utility model, can there is following outstanding technique effect:
1) cavity body 10 of the present utility model can be broken and be assembled, and brings up construction flexibly, without using disruptive methodExtract, reduce constructional difficulties, ensure architecture quality simultaneously.
2) cavity body 10 of the present utility model can directly replace pipeline binding site and the tapping point of prior art, solves existingThere is the infringement of technology to floor construction, promote the service life of floor.
3) complete prefabricated Dual-side hollow floor has improved prefabricated rate-saving construction cost greatly, and quick-mounting is spelled soon, reducesThe generation (relatively cast-in-place lid building can reduce more than 50% structure class waste material, for example concrete and reinforcing bar) of construction waste material, greatlyPromote floor quality, two-sided prefabricated except ceiling has also promoted the quality on floor, (the smooth fineness of platform and smallpox can improveTo 1 to 1000, smoothness can be promoted to 35 μ m)
In sum, cavity body of the present utility model, designs ingeniously, can in not solidified concrete, not float, with solidifyingGu after concrete floor in conjunction with can extract later, can not cause cavity internal water accumulation, simple for structure, be convenient to storage and transport,Safety economy environmental protection, relevant cassette ceiling can be prefabricated, thereby reduce on-the-spot reinforcing bar and the cast cassette ceiling laid, and improves prefabricatedRate, time saving and energy saving, reduce costs, the reduction of erection time, safety economy environmental protection, is suitable for large-scale promotion application.
One skilled in the art will understand that embodiment of the present utility model conduct shown in foregoing description and accompanying drawingDo not limit for example the utility model.
As can be seen here, the purpose of this utility model is complete and be effectively achieved. Function of the present utility model andStructural principle is shown in an embodiment and is illustrated, is not deviating under described principle, and embodiment can be done any amendment. InstituteWith, the utility model has comprised all distortion embodiments based on claim spirit and claim scope.
