Description

A kind of permeability type combination filling box of metal sheet

(1) technical field

The utility model relates to the packing material in a kind of reinforced concrete hollow floor structure, and especially a kind of permeability type combination filling box of metal 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, I once proposed 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 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 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, the hollow rate of floor is not high; 3, more its globality that causes of parts forming packing material product is bad; 4, Product transport cost is high; 5, 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; 6, 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, stiffener, spillage cylinder, the strip metal thin plate being less than 1mm at thickness forms intensive mesh by the mode of punching molding, every sheet metal sheet roof covering has 2 road folding lines, between 2 road folding lines of metal sheet roof covering and the central part of metal sheet roof covering width range have the slurry leakage hole of a size >=50mm and≤150mm, by the two ends of metal sheet roof covering along folding line towards equidirectional 90-degree bent respectively, formed and there is the U-shaped structural component in three faces and lower assembly, spillage cylinder and road, each direction at least 2 stiffener are installed in upper assembly and lower assembly, spillage cylinder and slurry leakage hole position coincide mutually, upper assembly and lower assembly are buckled togather, by the mode that welding or peg anchoring or iron wire colligation or buckle connect, two U-shaped butt joint edges between upper assembly and lower assembly are joined together to form filling box.

The strip metal thin plate being less than 1mm at thickness forms intensive mesh by the mode of punching molding, can greatly be reduced in concreting process the buoyancy that filling box produces by the filling box of this band dense mesh manufacture.Strip metal thin plate presses one 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.Opening a slurry leakage hole at the central part of metal sheet roof covering is to install spillage cylinder, after spillage cylinder is set, when can make larger by the size of filling box (usual filling box short side dimension can >=700mm), while raising floor hollow rate, ensure that filling box lower concrete is built closely knit; In construction, spillage cylinder can strengthen the vertical rigidity of filling box, after the concrete setting in spillage cylinder, increases and connects quite and a kind of effect of pillar, can improve the ability of flooring bearing load between the upper and lower edge of a wing of floor.Because the rigidity of metal sheet roof covering is very little, easily deform under the effect of external force, in upper assembly and lower assembly, 2 road stiffeners are at least installed in each direction, are to strengthen metal sheet roof covering.First, stiffener and spillage cylinder together constitute the vertical applied force component of filling box, prevent the upper surface of filling box in work progress from larger distortion occurring; Secondly, stiffener becomes again the support of side-wall metallic thin plate, greatly can strengthen the horizontal rigidity of sidewall.

Of the present utility modelly be characterised in that mesh short size >=4mm on metal sheet roof covering and≤12mm, grow 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, when installing filling box, plasma resistance sheet tilts towards the lateral direction of 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, by forming the intensive mesh having obvious size on metal sheet roof covering, plasma resistance sheet is formed by sheet metal out die-cut in mesh, 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.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.

Of the present utility modelly be characterised in that metal sheet roof covering has the stiffening rib utilizing self mother metal extruded along its length, stiffening rib is vertical with folding line, height >=the 4mm of stiffening rib, adjacent stiffening rib is parallel to each other, adjacent stiffening rib spacing >=50mm and≤150mm, stiffening rib on filling box 4 sidewalls is all vertical with soffit with the upper surface of filling box, and stiffening rib is positioned at the outside of filling box sidewall, upper surface and soffit.Filling box upper surface and arranging of soffit stiffening rib can improve the ability that filling box bears vertical load.Stiffening rib is vertical with folding line, first be easy to realize from machining, add the upper assembly that limited in aforementioned schemes and lower assembly is U-shaped structure, naturally ensure that the stiffening rib on sidewall is all vertical with soffit with the upper surface of filling box, greatly can strengthen the vertical rigidity of filling box like this.In the tecnical regulations of any hollow building cover, all there is clear and definite requirement (being generally >=10mm) to the distance on steel bar stress and packing material surface, when stiffening rib be positioned at the outside of filling box sidewall, upper surface and soffit and height >=10mm time, stiffening rib is except rising except the booster action of filling box, also play a part isolation reinforcing bar and filling box simultaneously, can reduce construction material cost, economic benefit is obvious.

Of the present utility modelly be characterised in that the accessory that stiffener can play the supporting role of horizontal and vertical direction simultaneously, the material of stiffener is metal material or plastic materials or cement class material, with welding or iron wire colligation or buckle connects or stiffener and upper assembly or lower assembly are fixed together by the mode of insertion of slotting.

Of the present utility modelly be characterised in that spillage cylinder plays spillage and vertical support, the flat shape of spillage cylinder is circular or oval or rectangle or polygon, the material of spillage cylinder is metal material or plastic materials or cement class material, with bonding or welding or iron wire colligation or buckle connects or spillage cylinder and upper assembly or lower assembly are fixed together by the mode of insertion of slotting.

Of the present utility modelly be characterised in that the upper surface be made up of upper assembly in filling box or the soffit be made up of lower assembly are the curved surface to filling box outer projection, the section configuration of curved surface is arc line type or broken line type, the edges of metal sheet shape forming filling box sidewall in corresponding upper assembly and lower assembly matches with soffit and upper surface butt joint edge shape respectively, the top of stiffener and spillage cylinder and bottom shape and also upper and lower surface configuration matches with filling box respectively.The upper and lower surface of filling box is the curved surface to projection, compared with pure rectangular cross section, slightly loses some hollow rates, but can obtain following effect: the degree that 1, can alleviate concrete girt strip stress concentration between filling box, and concrete is not easy to crack; 2, the concrete punch resistant capability in filling box top is improved; 3, filling box lower concrete is easily built closely knit.
