Description

Light steel-plastics floor and construction method thereof

The present invention is a kind of light steel-plastics floor and construction method thereof, belongs to building construction method and technology field, particularly the building technology of the big parts of building construction.

Human purpose of building building is to obtain safe and reliable from level to level vertical space, to satisfy the need of life activity.And the construction of flooring or roofing is topmost purpose and the content in the whole builing industry.Over more than 100 year, the construction method of building flooring mainly adopts steel concrete, and not only weight is big for it, work progress is miscellaneous, and execution conditions are poor, and community is polluted in the domain, and easily produce brittle fracture, and following poor stability, human safety in serious threat in contingency.

Purpose of the present invention is exactly in order to overcome and solve the construction employing steel concrete of flooring in the building construction, not only from weight is big, construction is miscellaneous, execution conditions are poor, community is polluted in the domain, and easily produce brittle fracture, the shortcoming and the problem of following poor stability etc., a kind of labor and material saving of research and design, simple and convenient from heavy and light, construction, can the intense industrialization civilized construction, the efficiency of construction height, applied widely, decorate good light steel-plastics floor and the construction method thereof of flexible, following safety.

The present invention realizes by subordinate's structure and method and technology scheme: the partial structurtes schematic diagram of light steel-plastics floor as depicted in figs. 1 and 2: C shape in the light steel-plastics floor and square frame shape steel local shape structural representation are as shown in Figure 3 and Figure 4.Light steel-plastics floor mainly by: floor plate 1, steel frame 2, foamed plastic core 3, bottom of the building plate 4 common combinations connect and compose, its mutual alignment and annexation are: steel frame 2 can use thin-walled C shape steel or the mutual quadrature up and down of square frame shape steel fastening to form by a kind of material that has the steel bayonet socket that is called, seal as floor plate 1 with the middle-high density particle board above the steel frame 2, seal as bottom of the building plate 4 with aluminium alloy plate or fire-proof board below, the light steel-plastics floor inner chamber fills full high-pressure foam plastics, and whole secure bond forms light steel-plastics floor.

The construction method of light steel-plastics floor is: preset the edge sealing angle steel on the side bar around the flooring, steel is upwards put by the spacing bayonet socket of bayonet socket, again another steel bayonet socket is placed on the bayonet socket of the steel that has set by vertical direction downwards, bayonet socket is up and down compressed mutually buckle and flatten up and down the close rib steel skeleton 2 that constitutes an orthogonal crossing perforation; At an amount of high-strength building viscose of the top airfoil pressure injection of steel frame 2, close assembly floor plate 1, and with Stainless Steel Self Tapping Screws the top airfoil of steel frame and go to the bottom (or adding corner fittings in addition) of floor plate are reinforced from bottom to top; The end aerofoil of the steel frame 2 also an amount of high-strength building viscose glue of pressure injection is pasted tight bottom of the building plate 4 and is cemented with it, uses the cavity body of the fastening formation light steel-plastics floor of screw again; High compression swelling fast with the liquid plastic raw material and the blowing agent injection flooring inner chamber of some, took place and forms foamed plastic in the short time in last appropriate location pinking on floor plate 1 rapidly, and full whole flooring inner chamber becomes foamed plastic core 3; With powerful adhesive-hardenings such as floor plate 1, bottom of the building plate 4 and steel frames 2 together, construction becomes light steel-plastics floor.Because plastics are after flooring inner chamber mesohigh foaming solidifies, all material that is about in the omnipotent flooring inner chamber cements tightly, and no matter any part is subjected to the external force effect can make the associating of each several part fellowship stressed by buffering transmission.

The present invention compared with prior art has following advantage and beneficial effect: (1) light steel-plastics floor does not have brittle fracture, can guarantee the eternal safety of user.Connect and compose the interior three-dimensional spatial skeleton because the light steel-plastics floor each several part is mutually tight, self just possessed fabulous rigidity and safety, do not had the hidden danger that flooring collapses suddenly and bursts apart extremely; (2) construction materials easy clean has been avoided steel concrete to build and must a large amount of mixing have been used the assorted material that looses, and causes the severe contamination that causes domain and community in the work progress; (3) eliminated destruction to earth environment.Owing to do not need the timber moulding, timber has lost maximum construction market, and people just can not go to cut down mountain forest yet; Without cement, the chimney flue dust of cement plant can reduce naturally to aerial discharge value; Without stone, people no longer go to cut into a mountain in a large number and get stone, also clear the way with regard to no longer worrying to be leveled off hilltops and destroyed natural greening or natural scenic spots in the far and near green hill in countryside, city; (4) design is simple and easy.Steel band has bayonet socket, can press the orthogonal fastening of orthogonal direction easily because by strict dimensioned manufacturing, clamping is very tight up and down, weld and the high strength viscose is bonding wait processing after, can guarantee to become mutually the stressed integral body of three-dimensional.In the actual drawing of floor structure, there are not the nitty-gritty details of the end muscle, gluten of various different sizes, negative muscle or the like to overtax one's nerves again; (5) safe ready.For common engineering user,,, do not have big unexpected safety problem yet and take place even oneself construct assembling as long as select material and operation according to technical requirements; (6) thickness reduces.Because the concrete and the topping of reinforced concrete floor bottom have no resistance to tension, can produce the crack once deforming, so the requirement of the cross section of floor is thicker, and design thickness adopts greater than 1/40 of short span.And in the light steel-plastics floor, usually the bottom of the building plate adopts thick aluminium sheet or other to bear the fabulous material formation of pulling force characteristic, sorrow that can not have the crack of appearance extremely, guaranteeing to use under the prerequisite of rigidity, the integral thickness of light steel-plastics floor just can attenuate, its design thickness can adopt and be about 1/60～1/70 of short span, is aided with and strengthens the construction measure that periphery connects, and just can guarantee being perfectly safe of structure use; (7) intense industrialization civilized construction.No longer occur standing in and the heavy physical labour operation such as make in the concrete firm by ramming, all carry out in working environment easily; (8) efficiency of construction height.Make a width of cloth reinforced concrete floor, criticize tens of procedures such as ash from upright fore-set, shut die plate, curved steel rolling muscle, placing of concrete, form removal maintenance, above the plate and bottom surface, at least take the cycle of 5～7 day time, and make the light steel-plastics floor of an identical size, only needed all to finish approximately in 1～2 hour; (9) decorate flexibly.The forming surface of concrete floor is quite coarse and crude, the indoor big cost finishing of must doing in addition could use, and in the light steel-plastics floor, because floor plate adopts and curvedly to press fabulous middle-high density fibrous nits plate of performance or PVC wood to mould material such as plate to make, but the plate face is level and smooth attractive in appearance and precompose shades of colour or the processing of material pattern, install just and can directly use, also can directly paste various senior earth materials, very flexible; (10) adapt to modernization life trend.In the concrete construction, how modern smart machine pipeline hangs in addition below floor, makees one false ceiling again and covers decoration, must spend a large amount of money, but also will waste the following part height space of flooring.And in light steel-plastics floor, then all pipelines can be laid within the omnipotent steel frame 2 before sealing bottom of the building plate 4 in advance, the bottom of the building plate 4 of light steel-plastics floor is smoothly meticulous, flower wide variety of materials and money can be decorated very high-grade ceiling in addition, even need to change pipeline in the future, penetrate in length and breadth again as long as remove old line.Even at short notice bottom of the building plate 4 is unloaded, remove the foamed plastics of inside, to lay pipeline again, and then sealed bottom of the building plate 4, injection moulding again also can not influence its upper strata owner's use and safety.As must at the bottom of smallpox, increasing modeling effect, also only need to connect the relevant interface of drawing at the bottom of the light steel-plastics floor, install equipment needed thereby after, can realize under whole moulding sunk panel etc. is connected in floor plate; (11) simplify the building trade management.As carry out in an all-round way and use after the light steel-plastics floor, the bulk cargos such as all sandstone cement in the concrete construction have been exempted, on-the-spot loaded down with trivial details sand, stone, the cement material is stacked, the size of reinforcing bar, lap length, the colligation position, template erection, concrete mix, water/binder ratio, cobble-stone diameter, the sand quality, fineness, sand content, the uniformity artificial or machine stirs, make compactness firm by ramming, the position that negative power reinforcing bar is controlled, maintenance after the cast or the like problem does not all exist, technical requirements is greatly simplified, the series supervision that silicate detects appraisal organization cooperates cancellation, and the severe and loaded down with trivial details management layer by layer of old industry just can progressively be withered away; (12) light steel-plastics floor is compared with reinforced concrete floor and is also had many premium properties: 1. weight saving.The unit weight of reinforced concrete floor is about 2800kg/m ³, the foamed plastic heart of light steel-plastics floor is about 280～500kg/m altogether together with omnipotent steel frame, floor plate, bottom of the building plate etc. ³, 6～10 times of weight savings; 2. save material.Prop up the top without formwork erection during construction and installation, not only can reduce mounting cost, saved material more greatly; 3. the material kind reduces.Because simple structure, material model are few, weight saving, material are formed and is greatly reduced; 4. freight volume reduces.Because material therefor is simple material such as the omnipotent steel of finished product, typing sheet material entirely, weight has only about 1/10 of steel concrete.In major works, 5. freight volume can reduce more than 10 times at least builds conveniently.Do not need to go to move back and forth the little reinforcing bar of a rule, the omnipotent steel that only needs to process is fastened mutually on side bar, forms omnipotent steel frame, installs floor plate and bottom of the building plate again, and injection moulding is filled and can be completed immediately.The whole erection process need only be used small machines such as electronic or pneumatic cutting machine, brill, screwdriver, viscose rifle, injection machine.Not only construction is very easy and convenient, can also exempt in traditional domain discarded a large amount of construction rubbish and cleanings, the cleaning place is tired; 6. safer reliable.Reinforced concrete floor is made up of various fragile materials fully, only just is maintained not avalanche by having placed a small amount of reinforcing bar pulling.But along with the of the remote past or factor affecting such as vibrations, impact that meet accident, cause the flooring distortion to surpass certain limit, soffit produces the crack, and can increase distortion at leisure, is having no brittle fracture to take place and avalanche suddenly among the caution.Such serious accident, all take place much every year on the earth now, particularly works as surprise attack incident or large-scale earthquake and come temporarily, can't bear disastrously especially to say.And light steel-plastics floor, main cohering by omnipotent steel frame, floor plate, bottom of the building plate and interior foamed plastic sealing thereof constitutes common stressed integral body, the material that does not have brittle fracture fully, and stress performance is very excellent, special in more important structure, its bottom of the building plate adopts the above sealings such as high-strength thick aluminium alloy plate of 2mm to weld, and gives full play to the high and non-damageable premium properties of metal material tensile strength, total is strongly fortified, certainly can reliable more and safety.

Below Figure of description is further specified as follows: the light steel-plastics floor partial structurtes schematic diagram that Fig. 1 manufactures for C shape steel frame, the light steel-plastics floor partial structurtes schematic diagram that Fig. 2 makes for square frame shape steel frame, Fig. 3 is a C beam steel shape structure partial schematic diagram, and Fig. 4 is a square frame shape steel shape and structure partial schematic diagram.Among each figure: 1 is that floor plate, 2 is that steel frame, 3 is that foamed plastic core, 4 is the bottom of the building plate.

Embodiments of the present invention can be as follows: as long as press Fig. 1～design shown in Figure 4, make the parts of floor plate 1, steel frame 2, bottom of the building plate 4 etc., build by composition, mutual alignment and annexation and the light steel-plastics floor construction method of the described light steel-plastics floor of top manual again, just can implement the present invention preferably.Building installation steps more specifically can be as follows: (1) fixes and welds the L steel on Zhou Bianliang; (2) steel suitable for reading and end opening steel have been cut out respectively by the both direction length of Zhou Bianliang; (3) stride direction at weak point earlier by the bayonet socket spacing and discharge steel suitable for reading; (4) the end opening steel is buckled in the bayonet socket of steel, buckles that to be compacted to top and bottom smooth; (5) for large span or large scale structure, also can as required the buckle junction be welded with metal with an amount of high strength viscose of electronic viscose rifle squeeze note at each face of bayonet socket junction up and down; (6) weld with the peripheral bearing of L steel-support and around shrouding, make steel frame and periphery be connected to become integral body; (7) an amount of high strength viscose of squeeze note on the steel frame face of forming is placed on it floor plate, and seam is not stayed in close assembly, but piece precoating viscose or fill out the jail with plastics weldering etc.; (8) the flexible cord pipe is penetrated in the steel frame, and draw interface,, then must when the discharging steel, just it be penetrated in the preformed hole in the steel web as adopting hard sleeve; (9) annotate an amount of high-strength viscose at the steel frame base pressure; (10) the bottom of the building plate of thick aluminium alloy plate or other material is sticked in steel frame and go to the bottom, and reinforce with the countersunk head Stainless Steel Self Tapping Screws, edge joint position in addition plastic welding or aluminium weldering polishes; (11) cotton plate appropriate location is bored plug hole and is observed aperture in the building, fast the pouring foaming plastics; (12) fill up plug hole and peep hole, paste flooring or terrace decoration or waterproof, anti-aging protection plane materiel, important position in addition plastics weldering etc. is carried out tight joint filling and is handled.

The scope of application of light steel-plastics floor:, also can be used for large span, pedestrian overcrossing and high speed road and bridge of load greatly applicable to theater, the lecture Room, conference centre, the stadiums of dwelling house, hotel, office building and the large span of general span.Light steel-plastics floor can be by plane, pyramid face or the large-scale poor grand shell face of design-build different shape.Light steel-plastics floor both can be done flooring usefulness, also can do body of wall and use.

The characteristics of large span light steel-plastics floor: its construction method and common span light steel-plastics floor are identical, just select for use the steel of the big ting model of corresponding difference to constitute by design.Longspan structure steel frame height is corresponding bigger, the also corresponding increase of formed injection moulding thickness space.In general, the unit area unit weight of large span light steel-plastics floor also wants light compared with the light steel-plastics floor of common span.Say that in principle span is big more, economic efficacy is more favourable than more; The large span light steel-plastics floor is compared with the large span space rack: 1. the structural thickness of space net rack is about 1/15 of span, and the structural thickness of light steel-plastics floor only is 1/60～1/70 of a span, structural thickness than space net rack reduces about 4～5 times, can save architectural space greatly; 2. the space net rack of large span only is suitable for building the roofing that large span covers, and is not suitable for constituting the structure space of multilayer.And light steel-plastics floor also is applicable to long-span roofing simultaneously, can build the multilayer space of large span; 3. all stressed member long term exposure of space truss structure are among air, even through antirust processing, the time is remote still can corrosion serious, and the maintenance expense is high, and trouble very.And light steel-plastics floor because steel frame tightly is wrapped among the foamed plastics, has been subjected to tight protection, forever can corrosion, must not do antirust processing in addition, and use by all means after building up, must not pay any maintenance cost spending again; 4. the roofing layer of rack is covered by a piece panel and constitutes, and a large amount of interfaces are overlapping to link to each other, and the processing trouble also must periodic inspection.And light steel-plastics floor hardens and becomes the seamless block that full wafer does not absorb water owing to all filling the foamed plastic high-pressure molding in the cavity, has anything but to ooze the phenomenon generation of splitting leakage, thereby does not need generally speaking to overhaul; 5. in the application life of space net rack, as adopting common iron, the life-span is decades only.And the life-span of light steel-plastics floor (roofing) adopts the middle-high density particle board to add waterproof anti-aging face, base plate high-strength aluminium alloy plate, heart material formations such as foaming polyamine fat by floor plate, because the Polyurethane material by floor plate and the sealing of bottom of the building plate can not wear out generally speaking, so the agent structure of light steel-plastics floor (roofing) just will can not damaged yet, as long as in time change the layer of protective material of external surface, the life-span of its agent structure also just almost can be Forever.
