Description

A kind of with bottom gas-permeable nets and the filling box of upper discharge hole

(1) technical field

The utility model relates to the packing material in a kind of reinforced concrete hollow floor structure, especially a kind of with bottom gas-permeable nets and the filling box of upper discharge hole, belongs to buildings in general structure field.

(2) background technology

At building field, along with large-span concrete structure is increasing, increasing floor adopts hollow floor structure technology.Replace part concrete substantially can not affect the stress performance of structure with lightweight filler, but greatly can alleviate the deadweight of structure.

In previous hollow building cover, make pipe of cement and cement box as packing material using Qiu Zeyou, Wang Benmiao scholar's proposition high-strength cement that is representative, but the goods of cement class are from great.Afterwards, polyphenyl foam class material is introduced in hollow building cover by I, I successively proposed the technology such as " a kind of light foam material filling member with reinforced hard " (ZL200420077923.9) and " a kind of foam material filling box with enhancement Layer and slurry leakage hole " (ZL201010554837.2), and these technology are used widely in engineering.

But for built-in packing material, no matter polyphenyl class or cement class material, all will produce larger buoyancy in construction.According to Archimedes' principle, as long as the unit weight of packing material is less than concrete density, in the process of concreting, certainly lead to buoyancy.In order to overcome buoyancy, to take several steps in construction and carrying out anti-floating, except expensive, take a lot of work, time-consuming except, also larger to the damage of plate soffit formwork, and once certain road technical measures packing material that causes not in place floats, bring very large potential safety hazard by structure.Although it is light that the defect also existed in addition is exactly material, shared volume causes greatly cost of transportation large.

The concept of reinforcing mat is introduced hollow building cover packing material by Mr. Guo Wuchang the earliest, and 2011, Guo Wuchang proposed " a kind of obturator of filling concrete in situ " (ZL201120161932.6); After, Mr. Guo proposes again " a kind of cast-in-place concrete cored " (ZL201420109836.0), in the art, Mr. Guo is clear and definite " being provided with core " further before upper and lower steel mesh reinforcement, and propose " displacement and the flotation issue " existing for structure solution Conventional filler material that utilize " steel mesh reinforcement ".But, first clearly proposition steel mesh solve buoyancy problem be Wang Benmiao, 2013, he proposed " cast-in-situ hollow building roof of the netted box component pore-forming of a kind of combined type " (CN203514592U).In the art, Mr. Wang utilizes the gas permeability of mesh greatly to reduce to eliminate even completely the buoyancy of packing material first, ensure that concrete can not flow in packing material by the maximum size controlling mesh, utilize moisture surface tension force that moisture can not be infiltrated in packing material.After, Mr. Wang proposes the technology such as " a kind of steel mesh and organic object combine the cast-in-situ hollow building roof of pore-forming " (CN104005501A), " cast-in-situ hollow building roof of a kind of steel mesh and gas tube combination box pore-forming " (CN103967181A) and " a kind of steel mesh and thin plate combine the hollow building cover of pore-forming " (CN104631679A) again successively.Above-mentioned correlation technique brings revolutionary change to whole hollow building cover industry, has formed the trend that whole industry whole updating is regenerated at present.

But, there is following defect respectively in the above-described techniques, mainly contain: 1, larger buoyancy can be produced in work progress; 2, the vertical and lateral stiffness of packing material product is smaller, and in the process of trampling with concreting personnel during construction, deformation of products is larger; 3, packing material volume is relatively little; 4, when packing material size comparatively large (as casing horizontal dimension close to 1mX1m time), bottom half concrete is not easy to build closely knit; 5, when pipeline longitudinal and transverse, oblique in floor is more and clash with packing material position, the smooth construction of pipeline cannot be ensured.

In this case, develop and a kind ofly both overcome the buoyancy of concreting process concrete to packing material, again rigidity comparatively large, effectively can ensure that the concreting of packing material bottom is closely knit and the box filling product facilitating pipeline construction, cost of transportation low, become urgent problem in present hollow superstructure.

(3) summary of the invention

In existing hollow building cover technology, there is packing material buoyancy and cause constructional difficulties more greatly, or the problems such as superstructure hollow rate is low, product rigidity is little, plate base concrete pouring quality cannot ensure, pipeline difficult arrangement, the purpose of this utility model is to provide a kind of filling box with bottom gas-permeable nets and upper discharge hole.
