Description

A kind of combined metal filling box with plasma resistance sheet

(1) technical field

The utility model relates to the packing material in a kind of reinforced concrete hollow floor structure, especially a kind of combined metal filling box with plasma resistance sheet, 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; Afterwards, in view of the goods of cement class are from afterwards great, the people such as Xu Yan proposed again the packing material of polyphenyl foam one class; Above-mentioned technology is all 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 metal reinforcing mat was just introduced hollow building cover in 2011 by me, and I proposes " a kind of obturator of filling concrete in situ " (ZL201120161932.6); I proposes again " a kind of cast-in-place concrete cored " (ZL201420109836.0) and " a kind of concrete hollow board fills core " (ZL201520061689.9) later.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 hollow building cover pore-forming steel mesh and thin plate combine obturator " (CN104631681A) 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, more its globality that causes of parts forming packing material product is bad; 3, Product transport cost is high; 4, 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; 5, can not solve well and not only reduce buoyancy but also avoided concrete mortar to flow into this contradiction of packing material box house.

In this case, develop and a kind ofly both overcome the buoyancy of concreting process concrete to packing material, again good integrity, rigidity comparatively large, can effectively ensure packing material surrounding concrete pouring quality and the box filling product of convenient transportation, 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 packing material globality is poor, rigidity is less, effectively can not ensure that the problems such as high crossed by packing material surrounding concrete pouring quality or cost of transportation, and the purpose of this utility model is to provide a kind of combined metal filling box with plasma resistance sheet.

On the basis of existing technology, for achieving the above object, the technical solution adopted in the utility model is: this filling box comprises assembly, lower assembly, support, the strip metal thin plate being less than 1mm at thickness forms intensive mesh by the mode of punching molding, short size >=the 4mm of single mesh and≤12mm, the length of single mesh is to size >=5mm and≤15mm, from mesh, punched sheet metal out forms the plasma resistance sheet outwards tilted, one end of plasma resistance sheet is still connected with metal sheet roof covering mother metal, 2 road folding lines are had at every sheet metal sheet roof covering, by the two ends of metal sheet roof covering along folding line towards equidirectional 90-degree bent respectively, formed and there is the upper assembly of the U-shaped structure in three faces and lower assembly, at least 3 road supports are embedded in upper assembly and lower assembly, upper assembly and lower assembly are buckled togather, by the mode of welding or peg anchoring or iron wire colligation, two U-shaped butt joint edges between upper assembly and lower assembly are joined together to form filling box.In the prior aries such as CN104631681A, the critical component reticular lamina eliminating buoyancy effect is " making shaping the die-cut of special purpose machinery and expansion by same thin steel plate "; Steel sheet punches out the finedraw that many bar width can be ignored, be arranged according to certain rules, steel plate is stretched to both sides, make finedraw expand into regular net structure; This sizing grid can not be too large, stops concrete inflow filling box internal main will lean on the surface tension of moisture in concrete.And in this programme, the intensive mesh having obvious size is formed by the strip metal thin plate that is less than 1mm at thickness, punched sheet metal out forms plasma resistance sheet, can breathe freely and eliminate the buoyancy produced in concreting process in gap between mesh and plasma resistance sheet, the surface tension of moisture and the mechanical resistance of plasma resistance sheet stop concrete mortar to flow into filling box jointly.Verify through test of many times: mesh size can reach fundamental technics effect within aforementioned range, especially with the average of numerical value and upper lower limit value close to time best results.Be covered with mesh to press with on the strip metal thin plate of plasma resistance sheet together with folding line, along folding line, metal sheet roof covering is curved the upper assembly of U-shaped structure or lower assembly, in making, assembly and lower assembly and follow-up assembled process can be carried out in factory, more can carry out at the construction field (site).If upper for making assembly, lower assembly and follow-up assembled procedural arrangements are carried out at the construction field (site), because of transport of strip metal thin plate slices pile being got up, can greatly reduce the volume that equal number packing material is shared in transportation, conevying efficiency at least improves 5 times.In the prior aries such as CN104631681A, normally " steel mesh forms the monolithic molding tetrahedron of the top panel of hexahedron Cavity structural member, bottom panel and two sidewalls ", tetrahedral globality is obviously better, but 2 faces remaining in 6 faces form by with the free parts that aforementioned 4 faces are not directly connected, first the parts forming these 2 faces are large in installation process positioning difficulty, and secondly the globality of installation rear box is also poor.And in the technical program, for any one face in filling box, each face has at least a limit to be that mother metal is directly connected with mother metal by folding line and other face, the face of dissociating completely with other face is there is not in filling box, therefore, in assembled process, the effect do not checked and balance between coplanar must cause location each other convenient and assembled rear good integrity; Be foursquare casing for end face modal in engineering in addition, the size of the upper assembly of U-shaped structure and lower assembly in this programme, size and dimension are just the same, which reduce the quantity of manufacturing process Plays part, can greatly enhance productivity.In upper assembly and lower assembly, embed at least 3 road supports, except raising filling box vertical rigidity, the horizontal rigidity of filling box can also be strengthened, prevent filling box in work progress from producing distortion.

Of the present utility modelly be characterised in that plasma resistance sheet tilts to the lateral direction of filling box.Found through experiments: under the prerequisite ensureing exhaust, the tilting direction of plasma resistance sheet and concrete pouring quality have much relations.If plasma resistance sheet tilts to the direction, inner side of filling box, under concrete pressure effect, Zhang Yue great is got in gap between mesh and plasma resistance sheet, once concrete pressure is greater than the value of making a concerted effort of wawter tension and plasma resistance sheet mechanical resistance, plasma resistance sheet will continue to tilt to filling box inside, make concrete flow into filling box inner.If plasma resistance sheet tilts to the lateral direction of filling box, under concrete pressure effect, plasma resistance sheet has towards the closed trend of mesh, but die-cut mesh out can not be closed into plasma resistance sheet the degree that air all cannot penetrate again, therefore, reaching the technique effect greatly reducing buoyancy while, prevent again concrete from flowing into filling box inner.
