The concrete single-layer reinforcing steel bar mesh which is provided by the utility model can be widely applied to concrete structures and prestress concrete structures, and provides a convenient, rapid and effective solution for manufacturing and installing of the reinforcing steel bars, can solve the problem that a concrete protective layer can not be guaranteed caused by the connection of the reinforcing steel bar mesh, and has a wide market prospect.
Description
Technical field
The utility model belongs to civil construction project technical field, is specifically related to a kind of concrete individual layer steel mesh reinforcement.
Background technology
At present, in building, traffic, gardens and hydraulic engineering construction, often relate to a large amount of steel concrete and prestressed reinforced concrete engineering, in this type of engineering, the making of reinforcing bar, processing, transportation etc. are very important operations.The reinforcement fabrication of steel concrete and prestressed concrete, mostly still adopts manually and rolls, and not only construction quality is difficult to control, and speed of application is slow, thereby makes making, the high phenomenon ubiquity of processing cost.In recent years; along with the steel mesh reinforcement of produce in factory processing is applied gradually; above-mentioned phenomenon obtains improvement to a certain extent; but; because the current steel mesh reinforcement product number of plies has stacked the forming of two-layer reinforcing bar intersection; when mutually overlapping between steel mesh reinforcement; the number of plies of reinforcing bar reaches 4 layers or more; make the protective layer thickness of reinforcing bar uncontrollable; even in the situation that not overlapping; if as anticracking reinforcing bar, thereby also can make the inconsistent effect of prestressed of all directions that makes of protective layer thickness of ectonexine reinforcing bar different.Therefore the range of application of steel mesh reinforcement in engineering is restricted.
How to solve the inherent shortcoming in steel mesh reinforcement use procedure, the scope of application of expansion steel mesh reinforcement, thereby make reinforcement fabrication, processing, transportation in concrete work and prestressed concrete engineering more quick, a quality more assurance, cost is saved more, remains the important content in reinforced bar engineering.According to CNKI result for retrieval, at present about the product needed of steel mesh reinforcement is further improved.
Through inquiry, at present about the main patent of steel mesh reinforcement has:
June 14 nineteen ninety-five, Japanese Kuni Bosai Gijuzuga Co., Ltd. Shen profit plants, woody strong I invented " concrete bar " (application number: 95108307), provide a kind of preparation method of concrete bar.I.e. parallel in the longitudinal direction placement several bars, and the square crossing point that the reinforcing bar of itself and width is formed is fixed, an end points place of the reinforcing bar of width is formed simultaneously bending, by bend with approach bending part and be fixed up with the outmost reinforcing bar of top edge of length direction.Other one end at the reinforcing bar of width are fixed with the outmost reinforcing bar of lower edge of length direction.The present invention can guarantee that constructor, when the top edge of contact steel mesh reinforcement, is not hung wound by it, but do not consider the connection problem between the steel mesh reinforcement in construction.
December 4 nineteen ninety-five, its good invention of Xinqiu Steel Mesh Co., Ltd., Shanghai's model " welding cold-drawn bar net " (application number: 95246574), the utility model patent relates to a kind of welding cold-drawn bar net, comprise warp-wise reinforcing bar, broadwise reinforcing bar, warp-wise reinforcing bar becomes net with broadwise reinforcing bar with high frequency spot welding cross weld, and warp-wise reinforcing bar, broadwise reinforcing bar are cold-drawn bars.It is novel, simple in structure, the steel mesh reinforcement that has replaced traditional craft to roll with welding cold-drawn bar net, have that intensity is high, quality is unified, constructing operation is convenient, can the reduction of erection time and guarantee the advantages such as safety, and can save 25～30% rolled steel dosage, reducing the construction costs.The present invention only limits to cold-drawn bar material, and has the problem that can not effectively be connected between steel mesh reinforcement.
On September 3rd, 2006, China Mining University is permitted emerging bright, Zhang Nong, Li Guichen and has been invented " a kind of foldable reinforcing steel bar net " (application number: 200620076312), the utility model patent is a kind of foldable reinforcing steel bar net, is best suited for the supporting of mine laneway catalase layer.It comprises basic steel mesh reinforcement, and multiple basic steel mesh reinforcements are linked together, and is provided with the chain type connecting elements being connected as a single entity between multiple basic steel mesh reinforcements, and the online bottom of basic reinforcing bar is set to edge of a wing barb.Compared with prior art, improve the overall performance of supporting and protection structure, met the wall rock conditions such as complicated fragmentation, the argillization supporting demand that goes down into a mine.This metal dictyosome rigidity is large, and intensity is high, and integrality is good, supporting effect is good, and chain type syndeton has foldability, is easy to moulding, can be close to scar, can increase and decrease flexibly according to actual needs steel mesh reinforcement length, overlap joint firmly, construction is simple, has avoided connecing stubble overlapping, can use continuously, save material, volume after folding is little, is easy to mine car transportation, has practicality widely.The present invention adopts chain type connecting elements that steel mesh reinforcement is connected, but lack and connect between each reinforcing bar of composition steel mesh reinforcement, and the joint of each reinforcing bar is positioned on same section, can not meet the percentile requirement of maximum about bar splice area in bar splice length sections in reinforced concrete works, its scope of application is very restricted.
On July 20th, 2007, " reinforcing mesh structure " (application number: 200720155097) that the Cai Wen of Taiwan .Yuann Fuu IndustrY Co., Ltd. hair tonic is bright, it is characterized in that comprising: most bar reinforcing bars and most bar thread like body, wherein, between this majority bar reinforcing bar for being arranged in parallel, this majority bar reinforcing bar and most bar thread like body, for being staggered, utilize this thread like body around each reinforcing bar and in last end, to be provided with an ending portion, and the most bar reinforcing bars that originally disperse are separately weaved into a reinforcing mesh structure.The utility model is weaved into a reinforcing mesh structure by the most bar reinforcing bars that originally disperse separately, is beneficial to use and the carrying of reinforcing bar; Make reinforcing bar more rapid, convenient, safety when using and carry.Also there is the connection problem between steel mesh reinforcement in the present invention.
On August 24th, 2007, " reinforcing mesh for concrete " (application number: 200720174691) has been invented by Shandong Zhu Soviet Union and Eastern Europe, the utility model patent discloses a kind of reinforcing mesh for concrete, and this steel mesh reinforcement is braiding structure, transverse reinforcement and longitudinal reinforcement weaving, consists of.The utlity model has the advantage that cost is low, speed of application is fast, result of use is good, but can not meet connection request between steel mesh reinforcement.
