Problems solved by technology

Its shortcoming is that the use of thin-walled box-type filling parts can make the hollow floor the highest hollow rate and the lightest structure, but the fatal flaw is that it cannot ensure that the concrete under the thin-walled box is poured densely.
Its shortcoming is that the inflatable bag adopts a plane side wall structure, which does not conform to the concept of bionic mechanics of the eggshell, which greatly limits the mechanical performance and earthquake resistance of the floor

Embodiment 1

[0026] A hollow floor airbag, comprising an airbag body 1, the airbag body 1 is an eggshell-shaped ellipsoid structure, the airbag body 1 is provided with a fixing part 2, and the airbag body 1 is made of wear-resistant and corrosion-resistant canvas As a result, the fixing member 2 is a collar, and the collar is movably connected with the airbag body 1 .

[0027] Its construction method includes the following construction steps:

[0028] 1) According to the drawings and design requirements, mark the positioning, set up the formwork, lay the bottom steel bar 3, put the collar on the bottom steel bar and bind the bottom steel bar 3 so that the end of the binding wire faces downward;

[0029] 2) Reservation and pre-embedding of various pipelines according to design requirements;

[0030] 3) Bind the steel bars 4 of the densely ribbed beam so that the ends of the binding wires face down, install the airbag, fix the airbag body 1 with the collar, and fix the collar to the bottom ...

Embodiment 2

[0035] The difference between this embodiment and the first embodiment is that the fixing member 2 is a hoop.

[0036] Its construction method includes the following steps:

[0037] 1) According to the drawings and design requirements, mark the positioning, set up the formwork, lay the bottom steel bar 3 and bind it so that the end of the binding wire faces downward;

[0038] 2) Reservation and pre-embedding of various pipelines according to design requirements;

[0039] 3) Bind densely ribbed steel bars 4 so that the ends of the wires face down, install the airbag, and fix the airbag body 1 on the bottom steel bar 3 and the ribbed steel bar 4 through hoops;

[0040] 4) laying and binding the top layer of steel bars 5, and at the same time, the airbag body 1 is fixedly connected with the top layer of steel bars 5;

[0041] 5) Concrete is poured. Vibrate with a vibrator while pouring. Each airbag section is vibrated for 2-3 minutes to ensure that the concrete is dense and the...

Embodiment 3

[0044] The difference between this embodiment and Embodiment 1 is that the fixing part 2 is a U-shaped card. During construction, the airbag body 1 is fixed on the bottom steel bar 3, the rib beam steel bar 4 and the top layer steel bar 5 through the U-shaped card. .

[0045] Compared with the traditional hollow floor, the present invention has significantly improved engineering quality, cost, and construction period, and the compressive capacity is improved by more than 20% compared with the traditional hollow floor. The construction period can be effectively shortened by 30%, and the cost can be directly saved by more than 20%. It improves the quality of the project, shortens the construction period, and reduces the manpower, material and financial costs of project construction, bringing huge economic and social benefits.

Abstract

The invention discloses a hollow floor air bag and a construction method of cast-in-place hollow floors. The hollow floor air bag comprises air bag bodies in eggshell-shaped ellipsoid structures. Fixed parts are arranged on the air bag bodies, and a plurality of egg-shaped cavities are formed in the floor after concrete pouring, setting and hardening by aid of the bionic principle. The floor cavities have strong anti-pressure ability on the same pouring condition, and the loading capacity and the impact resistance of the hollow floors are greatly improved. The construction method is simple, convenient and easy to operate, the poured hollow floors have strong carrying capacity and good seismic resistance, the quality of the hollow floors is ensured, and the construction method is especially applied to the hollow floors of high-rise buildings in large-span structures.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a hollow floor air bag and a construction method for a cast-in-place hollow floor. technical background [0002] At present, the traditional method of cast-in-place reinforced concrete hollow floors is to set an inner mold in the concrete for pouring, and pull out the inner mold when the concrete hardens to a certain strength, thereby achieving the purpose of reducing the amount of concrete and the weight of the floor. The traditional inner mold The formwork is a thin-walled tube structure. During the construction process, it is necessary to set up connecting members or fixing materials to fix the inner formwork, which causes great inconvenience to the construction, low construction efficiency and high cost. [0003] The application number authorized on September 21, 2011 is 201010130223.1 Patent of Invention, which discloses a construction method for a ...
