(1) technical field

The utility model relates to the packing material in a kind of reinforced concrete hollow floor structure, especially a kind ofThe ventilative filling box of upper and lower pin-connected panel, belongs to buildings in general structure field.

(2) background technology

At building field, along with large-span concrete structure is increasing, increasing floor adopts hollowBuilding cover structure technology. Replace part concrete substantially can not affect the stressed property of structure with lightweight fillerCan, but the deadweight that can greatly alleviate structure.

In previous hollow building cover, the scholar taking Qiu Zeyou, Wang Benmiao as representative proposes to use high-strength cement systemMake pipe of cement and cement box as packing material, but the goods of cement class are from great. Afterwards, I will gatherBenzene foam class material is introduced in hollow building cover, and I successively proposed, and " a kind of lightweight with reinforced hard is sent outFoam material filling member " (ZL200420077923.9) with " a kind of expanded material with enhancement Layer and slurry leakage hole is filled outFill case " technology such as (ZL201010554837.2), these technology are used widely in engineering.

But, for built-in packing material, no matter polyphenyl class or cement class material, in construction allProduce larger buoyancy. According to Archimedes' principle, as long as the unit weight of packing material is less than concrete density,In the process of casting concrete, certainly lead to buoyancy. In order to overcome buoyancy, in construction, to take several stepsCarry out anti-floating, except expensive, take a lot of work, time-consuming, also larger to the damage of plate end template, once and certainThe technical measures packing material that causes not in place in road floats, and will bring very large potential safety hazard to structure.

Mr. Guo Wuchang introduces hollow building cover packing material,, Guo Wuchang in 2011 by the concept of reinforcing mat the earliest" a kind of obturator of filling concrete in situ " proposed (ZL201120161932.6); After, Mr. Guo carries again(ZL201420109836.0), in this technology, Mr. Guo is further bright to go out " a kind of cast-in-place concrete cored "Really " before upper and lower bar-mat reinforcement, be provided with core ", and propose to utilize the structure solution routine of " bar-mat reinforcement " to fill outFill material existing " displacement and floating problem ". But, clearly propose first to solve buoyancy problem with steel meshBe Wang Benmiao, 2013, he proposed " a kind of cast-in-place hollow building with combined type netted box component pore-formingLid " (CN203514592U). In this technology, Mr. Wang utilizes the gas permeability of mesh greatly to reduce very firstTo the buoyancy of eliminating packing material completely, ensure that by controlling the full-size of mesh concrete can not flow into and fill outFill in material, utilize moisture surface tension force that moisture can not infiltrated in packing material. After, Mr. Wang is land againContinuous propose " a kind of cast-in-situ hollow building roof that is combined into hole with steel mesh and organic object " (CN104005501A)," a kind of cast-in-situ hollow building roof with steel mesh and gas tube combination box pore-forming " is (CN103967181A) with " oneKind combine the hollow building cover of pore-forming with steel mesh and thin plate " technology such as (CN104631679A). Above-mentioned relevant skillArt brings revolutionary variation to whole hollow building cover industry, has formed at present whole industry whole updatingThe trend of regenerating.

There is respectively in the prior art following defect, mainly contain: 1, in work progress, can produce larger floatingPower; 2, the vertical and lateral stiffness of packing material product is smaller, when construction, tramples and build coagulation personnelIn the process of soil, deformation of products is larger; 3, packing material volume is relatively little; 4, when packing material size(while approaching 1mX1m as casing horizontal size) greatly, bottom half concrete is not easy to build closely knit; 5, whenLongitudinal and transverse, oblique pipeline is more and while clashing with packing material position in floor, cannot ensure pipelineSmooth construction.

In this case, develop a kind of buoyancy of concreting process concrete to packing material that both overcome,Again rigidity large, can effectively ensure that the concreting of packing material bottom is closely knit and facilitate pipeline construction, transportThe box filling product that cost is low, has become urgent problem in current hollow building cover.
