Abstract
The utility model relates to a large wire mesh floor used for building structure, comprising a longitudinal steel bar, a transverse steel bar, an anchoring steel bar and concrete. The longitudinal steel bar and the transverse steel bar are crossly arranged to form a network shape; the cross points are connected with spot welding; two anchoring steel bars in parallel arrangement are arranged at the periphery of an integral steel fabric sheet comprising the longitudinal and transversal steel bars; all the cross points between the anchoring steel bars and the longitudinal and transversal steel bars are connected with the spot welding. The utility model which has the advantages of high intensity, favorable structural property, saved material consumption and low cost is suitable for multi-story buildings and total-prefabricated tall buildings.
Description
The utility model is the big floor of a kind of building structural steel silk screen, and this floor can be adjusted size according to room-size, can adjust arrangement of reinforcement according to load level.The longitudinal reinforcement of steel fabric sheet all is connected with spot welding with place, the crosspoint of transverse reinforcement.
Building structure mainly contains and gives stress porous plate (batten), gives big floor of stress and the big floor of bi-steel in the prior art with floor.Fig. 1 is the production technology sketch that gives stress porous plate (batten).(4) be pedestal, (3) are electric winch, and hoist engine tension reinforcing steel bar (1) produces and gives stress.Go up concreting at reinforcing bar (1) then, make and give the stress floor, treat that maintenance expires then to cut off reinforcing bar between each piece floor.The defective of giving stress porous plate (batten) is: device therefor is many, complex process, and the production cycle is long, needs special production line and pedestal, reinforcing bar easily takes place in the reinforced bar stretching rupture suddenly, causes injury to personnel.Because of the spacing more than 10 centimetres is arranged, this part reinforcing bar is wasted between the every floor.Give the big floor of stress and to give the stress porous plate similar, also adopt the long-line pedestal production technology, except that the defective of stress porous plate is given in existence, also have following defective: plate is easily super thick, overweight, must use the high grade sacked cement.Fig. 2 is the big floor sketch of bi-steel.(5) (bi-steel is parallel by two, and spacing is 20～30 millimeters a vertical muscle and the spacing welding of some vertical with it bar dowels (horizontal bar) by 80～100 millimeters, the terraced lattice type skeleton of composition for horizontal bi-steel.) (6) be vertical bi-steel, its structure is with laterally bi-steel is identical.The defective of the big floor of bi-steel is: must special-purpose bi-steel welding machine (but bi-steel welding machine quality does not pass a test at present).Vertically, laterally the bi-steel of configuration works independently separately isolatedly respectively, compartment is brought into play thereby influence the reinforcing bar potentiality each other.In length and breadth to the anchor rib that is provided with being arranged respectively, thereby increased steel using amount promptly in length and breadth to bi-steel hyphen muscle separately.Every kind of reinforcing bar has only a kind of effect, promptly principal rod, anchor rib be provided with respectively, dual-purpose not mutually, thereby increased steel using amount.Carry out colligation to bi-steel for fixing its position in length and breadth, also improved cost.In addition because in length and breadth to bi-steel works in isolation separately, so that influenced the structural performance of big floor.
The purpose of this utility model provide a kind ofly have the intensity height, structural performance is good, material consumption is few, the big floor of building structural steel silk screen that cost is low.
The big floor of building structural steel silk screen described in the utility model is made up of longitudinal reinforcement, transverse reinforcement, anchor bar and concrete four parts, longitudinal reinforcement becomes latticed with the transverse reinforcement orthogonal arrangement, the crosspoint all connects with spot welding, at the whole steel fabric sheet periphery that is made of the vertical, horizontal reinforcing bar two anchor bars that are arranged in parallel are set, anchor bar all is connected with spot welding with the crosspoint of longitudinal reinforcement or transverse reinforcement.
Below in conjunction with drawings and Examples the utility model is elaborated:
Fig. 3,4 is respectively vertical view of the present utility model and elevation.(7) be longitudinal reinforcement, (8) are transverse reinforcement, and (9) are two parallel anchor bars, and (10) are body of wall.Reinforcing system cold-drawn low-carbon wire in the utility model, the cement high-mark cement that needn't non-ly be packed in bag can adopt cement in bulk.As shown in Figure 3, the utility model adopts gauze wire cloth chip structure, and the floor size can be adjusted with room-size.Longitudinal reinforcement (7) is orthogonal with transverse reinforcement (8), all connects with spot welding in all crosspoints; At the periphery of reinforced mesh, with each limit two anchor bars parallel to each other (9) are set abreast, anchor bar (9) all is connected with spot welding with longitudinal reinforcement (7) all crosspoints with transverse reinforcement (8).As shown in Figure 4, the position of anchor bar (9) after big floor is installed is within body of wall, and promptly anchor bar (9) is in big floor bearing length scope.In longitudinal reinforcement (7), all there is cold pier nose the termination of transverse reinforcement (8) and anchor bar (9), and the effect of cold pier nose is to replenish anchoring strength.After whole steel fabric sheet spot welding is finished, the net sheet is inserted in the template (using topotype) more, concreting treats that maintenance expires then, can lift by crane transportation.
The cost of floor depends on amount of reinforcement, and steel using amount of the present utility model is that the 1/5～1/3(steel using amount that gives the stress porous plate, gives the big floor of stress and the big floor steel using amount of bi-steel is domestic minimum). Therefore, economic benefit of the present utility model is extremely remarkable. Because the utility model intensity height (through ten big floor tests), strength assurance coefficient is at 1.83～2.41. Factor of safety against cracking is 1.20～1.5 (the utility model is the non-stress plate that gives, and this nothing cracking resistance requires), and cracking resistance is superior. Rigidity is big, and deflection span ratio is no more than 1/120 during destruction, and mark carries lower deflection span ratio 1/791～1/4895, only occurs splitting wide 1.5 millimeters destruction marking during test, is ductile fracture, and other destruction marking does not all occur. Therefore, because the utility model structural behaviour significantly is better than domestic existing floor, so not only can be used for tier building, and the skyscraper that can be used for complete assemblingization, to build the cycle that the assembled integral floor of continuing to use for a long time cast-in-situ floor causes long for solution, and progress is slow, high material consumption, the high cost problem provides a new way that gets twice the result with half the effort, and the utility model is except steel using amount little (whole nation is minimum), outside structural behaviour is superior, adopt simultaneously the utility model can simplify technology, reduce operation, minimizing equipment, do not need special production line, pedestal, do not need special means of transport, be easy to promote, be convenient to start. Give the brittle failure of stress plate, the hole of collapsing in producing has not existed in the utility model. Give stress porous plate (batten) and come off in a large number when earthquake, the problem that seriously causes casualties also is able to thorough solution. Thereby have significant economic benefit and a social benefit.
