Description
Technical field
The present invention relates to be applicable in the geotechnical grid concrete construction Combined geotechnical grid stretch-drawing device especially used in the side slope construction of prevention work such as hydraulic engineering channel, dyke.
Background technology
Geotechnical grid is China's a kind of New Geosynthetics that introduction of foreign technology is produced in recent years, is to take polyolefin as base material, adds special additive, a kind of three-dimensional cellular structure be welded through high-tenacity.The lattice chamber is collapsible, and the visual requirement of engineering of its dimensions is adjusted.When having load year to be applied to above geotechnical grid, the three-dimensional mesh structure of geotechnical grid can limit flowing of packing material and make its reinforcement, produce the flexible structure that side direction is disperseed, most of vertical force is changed into to lateral force, thereby greatly reduce actual load, strengthen supporting capacity, reduced sedimentation; Its another important function is as Flexible formwork assembly, filler is divided into to the plate of mutual linking, utilizes the characteristics that its elongation rate is larger, can adapt to the larger vertical inhomogeneous deformation of plate.Geotechnical grid anti-freezing property excellence, can resist larger frost-heaving deformation.In construction of water conservancy works, the geotechnical grid concrete slab, as a kind of novel channel revetment structure, has more excellent frost heaving resistant deformability.Its basic structure is: the geotechnical grid of take after launching is framework, and cast-in-situ concrete in it forms geotechnical grid concrete slab structure.The effect of geotechnical grid is that concrete slab organically is divided into to piece, and mutual linking forms flexible structure, prevents from producing and heaving the phenomenons such as built, slippage in strong frost heave district.The application of geotechnical grid makes the easy vibration compacting of the indoor concrete of lattice, improves concrete density, thereby improves the concrete work performance.Be conducive to domatic construction, improve construction quality, relatively be applicable to the channel without the antiseepage requirement, not only can reduce the concrete thickness of slab and can also save reinforcing bar, reduce construction costs.But there is following problem in current geotechnical grid: because geotechnical grid is flexible material, in concreting process, as improper as PROCESS FOR TREATMENT, often cause the distortion of lattice chamber grid, both affected the appearance effect of lattice chamber pattern, also plaid matching chamber concrete structure has certain influence; The tensioning equipment framework integral rigidity that old-fashioned angle steel is welded is inadequate, and easily distortion, affect construction quality; The repeat usage of the framework be welded into by angle steel is not high, cleans more difficult; A set of tensioning equipment can only corresponding dimension lattice chamber grid, need many covering devices of making plurality of specifications could meet construction requirement, strengthened construction cost; The angle steel that is fixed dimension due to tensioning equipment is welded, and can't carry out freely expanding and shrinking for the different work face; Can only do the support of above-below direction and draw, left and right directions can't support and draw.
Summary of the invention
the technical problem to be solved in the present invention is to provide a kind ofcombined geotechnical grid stretch-drawing device, this device is not yielding, can guarantee that grid relaxation is even, guarantees construction quality.
the problem existed in order to solve prior art, the technical solution used in the present invention is:
combined geotechnical grid stretch-drawing device, includethree-dimensional linkage, combination square steel linkage section, fixedly bar slide and adjustable rod type slide block, described combination square steel linkage section and three-dimensional linkage are assembled into quadrilateral frame, be provided with fixedly bar slide on the lower frame of quadrilateral frame and left frame, fixedly the top of bar slide is welded with tension rod; Be provided with the adjustable rod type slide block on the left frame of quadrilateral frame and upper side frame, the top of adjustable rod type slide block is set side by side with fixed screw pole socket and mobile spiral shell piece, one end of lead screw through after mobile spiral shell piece with snap in the fixed screw pole socket, the other end of lead screw is connected with regulating handle, on mobile spiral shell piece, is welded with tension rod.
described three-dimensional linkagebe the T-shaped device be welded into by square steel, on three T-shaped ports, be respectively arranged with shape of the mouth as one speaks external socket, the external socket both sides are provided with two circular bayonet sockets.
described combination square steel linkage sectionone end is provided with interior socket, is provided with the connection buckle on interior socket,
combination square steel linkage sectionthe other end is provided with shape of the mouth as one speaks external socket, and the both sides of external socket are provided with circular bayonet socket.
advantage and effect that the present invention has are:
combined geotechnical grid stretch-drawing device of the present invention be bycombination square steel linkage section and four three-dimensional linkages are assembled into a quadrilateral frame, are provided with fixedly bar slide and adjustable rod type slide block on the frame of quadrilateral frame.Made because main body frame adopts square steel, can make like this framework no matter along channel side slopes direction or water (flow) direction, extend and all can guarantee the rigidity that it is enough, not yielding, improve repeat usage; In transportation, installation, work progress, unavoidably there will be the people for trampling, cal rolling, the damage such as shocks suddenly, the good service behaviour of square steel can guarantee that the distortion of framework is very little, the assurance construction quality; Be convenient to the concrete that cleaning is attached to the framework surface in work progress, be conducive to the maintenance of framework.Because the framework of whole device can Optional assembling and dismounting, therefore depositing, the link such as transportation can conserve space, attenuating expense expenditure.The spacing of the slide block arranged on the frame due to quadrilateral frame is adjustable, moving slider just can adapt to different grid supports by the spacing between adjusting slider and draw, be provided with tension rod, regulating handle, lead screw, mobile spiral shell piece on slide block, rotate regulating handle and can make the whole relaxation of geotechnical grid grid, guarantee that grid relaxation is even, carry out combination collocation for the different work face by different linkage sections and just can make framework freely expand on both direction and shrink, to meet the canal lining construction of different size, different wide cuts.Owing to having arranged the tension rod with regulating handle on the upper frame at tensioning equipment and correct frame simultaneously, therefore can do support upper and lower, the left and right both direction and draw.The present invention can make the whole relaxation of geotechnical grid grid, guarantee that grid relaxation is even, simple installation is easily gone, size is adjustable, not only can any combination, fractionation, can also regulate the size of geotechnical grid grid stretching force, for the geotechnical grid of different grid specifications, different wide cuts, the execution conditions of different length of slopes have good compliance.Can be repeatedly used engineering outward appearance better appearance.Tensioning equipment framework integral rigidity is good, not yielding, can guarantee construction quality, improves efficiency of construction.
