Abstract

The utility model relates to a novel conveniently make up formula geogrid constitutes the grid structure of grid by many roots strip, and both ends rib width is charitable 2~3 times of inside rib about it, and the both ends rib has erection joint spare, and one end is groove structure, and the recess is the swallow -tail form structure, and on the recess and be equipped with two fore shafts, the fore shaft is the symmetric distribution in the recess. The other end has the connection discount of reciprocal distribution with it, and discount upper portion is toper platform form. The discount links closely in the fore shaft, is difficult for droing. The rib at both ends is after the connecting piece is connected, and the upper end is on same horizontal plane, and the atress is even. Construction convenience is swift, tight lock hard takes off after the straining, compressive strength is high, has convenient, the rapid characteristics of combination.

Description

A kind of New-type instant Combined earthwork grid

Technical field

This utility model belongs to one and facilitates Combined earthwork grid, belongs to civil engineering component technology field。

Background technology

GSZ is current domestic a kind of new civil engineering material, has been widely used in the middle of the structure of the protection of slope, danger, soft foundation process, reinforced earth bulkhead engineering and some high-bearing capacities。In the prior art, GSZ is adopted one-shot forming or Combination Welding to reticulate cell structure by ribbed belt (polyethylene wraps steel wire and makes or make for polypropylene etc.)。One-time formed GSZ existing problems are: can not be sufficiently tensile, and volume is long is affected by restriction with fabric width, and overlength transport is limited；During laying, overlapping the slot is more, work consuming consumptive material, adds construction cost。GSZ, connects the method being generally adopted rope colligation, and its attachment force, long-term behaviour, colligation efficiency, operation convenience etc. are all restricted。When GSZ overlap being carried out colligation along lapping direction, not only intensity does not reach more preferably effect, and creates stacking of grid material, have impact on soil and grid effective Stress Transfer each other to a certain extent。

Utility model content

For the deficiency that above-mentioned GSZ exists, the purpose of this utility model be in that to provide one can combination in any at the construction field (site) as required, not only combined and instant, rapidly, and tensile strength is higher, node firmly facilitates Combined earthwork grid。Overlapping the slot is few, easy to operate, and colligation efficiency is high, reduces construction cost。

The technical solution of the utility model is achieved in that and facilitates Combined earthwork grid, including the ribbed belt being vertically and horizontally arranged into grid, connector compresses and connects。

The purpose of this utility model is realized by following structure: this utility model is a kind of GSZ with connector, the network of grid it is made up of many rib, two ends rib width is more than the width of interior ribs, its two ends installation connecting element, one end is groove structure, groove has fore shaft, the other end is with discount, adjacent two connectors be combined with each other, on discount card fore shaft in a groove, after the rib at two ends is connected part connection, upper end is in same level, make its uniform force, be unlikely to deform。Two adjacent width GSZs can be linked together fully by this utility model by two end connections, makes it to form unified entirety, combined effect, is greatly improved mass action effect and the tensile strength of GSZ。The attachment structure of this utility model swallow-tail form, it is possible to bear bigger horizontal force, connects reliable, stable。

Preferably, fore shaft is symmetrical in a groove。

Preferably, two ends, left and right rib width is 2～3 times that interior ribs is generous。

Preferably, each horizontal rib connects a connector。

Preferably, after the rib at two ends is connected part connection, upper transverse plane is still in same level。

Two adjacent width GSZs can be linked together fully by this utility model by two end connections, makes it to form unified entirety, combined effect, is greatly improved mass action effect and the tensile strength of GSZ。The attachment structure of this utility model swallow-tail form, it is possible to bear bigger horizontal force, connects reliable, stable。

Detailed description of the invention

Embodiment 1: as it is shown in figure 1, Combined earthwork grid of the present utility model, be made up of rib 1 and rib 2, the width of rib 2 is 2～3 times of rib 1 width, and rib can be wrapped steel wire by prior art polyethylene and make or make for polypropylene。On rib 2 and with connector 3, two ends installation connecting element, one end is groove structure, and the other end is discount structure。In construction process, adjacent two grid ends are connected buckle overlay in a vertical plane, firmly the discount structure on connector is pressed into card and is filled to the fore shaft place that Connection Card is detained in part recess so that it is combine closely, namely complete the connection of two adjacent GSZs。Each horizontal rib connects a connector, and connector connects two adjacent GSZs, and two width GSZs link together fully, forms unified entirety。

Embodiment 2: be illustrated in figure 2 the structural representation of connecting elements, its two ends installation connecting element, one end is groove structure, and the other end is discount structure, and adjacent two connectors be combined with each other, and discount 5 is installed on the fore shaft 4 on groove。Adopt and there is certain elastic engineering plastics raw material as discount so that it is be closely coupled with fore shaft 4。In construction process, adjacent two grid ends are connected buckle overlay in a vertical plane, firmly the discount structure on connector is pressed into card and is filled to the fore shaft place that Connection Card is detained in part recess, after the rib at two ends is connected part connection, upper transverse plane is still in same level, make it combine closely, namely complete the connection of two adjacent GSZs。

Embodiment 3: groove structure schematic diagram as shown in Figure 3, groove is dovetail shaped, it is possible to bear bigger horizontal pull。Fore shaft is symmetrical in a groove, makes groove left and right uniform force, is unlikely to deform。

Embodiment 4: be illustrated in figure 4 the discount structural representation of connector, discount 5 adopts has certain elastic engineering plastics, and D1 is slightly less than D3, D2 less than D3。

Claims
