Description
Technical field
The present invention relates to a kind of geotechnical grid of enclosed insert, belong to technical field of civil engineering.
Background technology
Geotechnical grid is used widely due to its superior reinforcement performance in civil engineering.But the geotechnical grid that existing plug-in unit connects, be all use the U-shaped plug-in unit of double end, because its structure is simple, double end U-shaped plug-in unit free end is unfixed in transport and use procedure, the U-shaped plug-in unit of double end is easily separated with rib tape and comes off, thus causes lattice room to lose the effect of self; When the free end installation fixing piece of the U-shaped plug-in unit of double end is fixed, because stator is very thin and little installation difficulty is large and consuming time, and stator is all be placed in the inserted link draw-in groove of the U-shaped plug-in unit of double end, gap between them is very large, stator is not connected with the U-shaped plug-in unit of double end, stator and the U-shaped plug-in unit of double end are not an entirety, during transport in lattice room and engineering use, the position of the stator of the U-shaped plug-in unit of double end is easily moved even to cause and comes off, cause the node of lattice room to be easily moved even node failure, thus affect the result of use of geotechnical grid.
The U-shaped double-end plug-in unit of current use, the inserted link of plug-in unit is not parallel to each other and perpendicular to fixing end face, in engineering uses, the rib tape of Nodes and the inserted link contact wire of plug-in unit are both not parallel not vertical with reinforcement length direction yet, cause the rib tape discontinuity in the direction of the width on node, the overall stretching resistance of rib tape is declined, affects the life-span of geotechnical grid.
Summary of the invention
For above-mentioned defect, the object of the present invention is to provide a kind of bonding strength high, uniform force on Nodes rib tape width, rib tape both sides connect the geotechnical grid of a kind of enclosed insert of slip-off preventing near plug-in unit both ends of the surface.
The technical solution adopted in the present invention is: comprise rib tape, ∏ type double-end plug-in unit and stator, each node of geotechnical grid is formed by the socket connection of ∏ type double-end plug-in unit, two rib tape same positions of Nodes all have the equal finedraw of length, inserted link two of ∏ type double-end plug-in unit is staggered through the finedraw in two rib tape successively respectively, two rib tape socket connections together, installation fixing piece on the inserted link of ∏ type double-end plug-in unit is also fixing, and rib tape both sides are near plug-in unit both ends of the surface.
The inserted link of above-mentioned ∏ type double-end plug-in unit, it is characterized in that: the inserted link of plug-in unit is parallel to each other and perpendicular to fixing end face, the geometry contacting inserted link any point cross section with rib tape is identical, the inserted link of ∏ type double-end plug-in unit arranges the fixed point of different profile, for fixing of the different fixed form of applicable stator.
The stator of above-mentioned use is characterized in that: material and the ∏ type double-end plug-in unit of stator are identical or different.
The above-mentioned inserted link of ∏ type double-end plug-in unit and the fixed form of stator: weld, latch is connected, bayonet lock connects or tie up.
The material of above-mentioned ∏ type double-end plug-in unit is steel nail or macromolecular material.
Above-mentioned rib tape is the composite material of macromolecular material or other material and high polymer.
Advantage of the present invention is: bonding strength is high, can prevent rib tape and plug-in unit from coming off, and effectively stops distortion and the movement of lattice room node, ensures that the node structure of geotechnical grid is stablized and rib tape uniform stressed, extends the application life of geotechnical grid.
