Abstract
The utility model relates to a gasket for welded fastening waterproof board, plastic spacer include the gasket body the center of gasket body is provided with the blind hole, and the bottom of blind hole sets up the jack, and the terminal surface that wherein sets up the blind hole is inclined plane or cambered surface, and the cross -section that makes the gasket body forms the structure of round platform form roughly, the utility model provides a present gasket is difficult forms effective face of weld, defect that the gasket was extracted easily, the utility model discloses welding rear cushion piece is difficult for breaking away from with the waterproof board, and the coiled material is difficult when torn by external force is destroyed.
Description
Technical field
This utility model relate to a kind of for tunnel, the Combined concrete liner structure such as tunnel, subway, underground pipe gallery for laying the solderable plastic spacer of splash guard/waterproof roll, belong to waterproof material auxiliary material field.
Background technology
The composite lining structures such as tunnel, tunnel, subway, underground pipe gallery generally use thermoplasticity welding gasket implement non-woven fabrics cushion to fix and the provisional paving extension of waterproof roll.Waterproof roll commonly used material has EVA, HDPE, LLDPE, ECB etc., and the many employings of conventional spacers make with the material of material, and moulding mostly is thin-wall circular dish-type.In welding process, easily cause coiled material by burn-through, the problem of not prison welding；After welding, pad easily distorts and comes off with coiled material or be together pulled out together with nailing；During finally pouring two lining concrete extrusion, waterproof roll is torn and ruptures the leak source forming unrepairable by welding gasket fixing point.
Simultaneously rough because of underground engineering basal planes such as tunnel, tunnel, underground pipe galleries, the thermoplasticity pad of disc type is difficult to be formed with splash guard effectively weld；And welding process Intermediate gasket material is difficult to melt, easily cause splash guard burn-through；The Material Strength of welding gasket, higher than after splash guard, can cause splash guard tear failure in by external force extrusion process used for forming.
Utility model content
Technical problem to be solved in the utility model is to provide for a kind of pad overcoming drawbacks described above, it is achieved the technical scheme of above-mentioned purpose is as follows:
A kind of pad for being welded and fixed splash guard, including shim body, it is characterised in that: described shim body be provided centrally with blind hole, the bottom of blind hole arranges jack, the end face being provided with blind hole is inclined-plane or cambered surface, makes the cross section of shim body generally form round table-like structure.
Preferably, the annular groove end face of jack having with jack as the center of circle is set, the ribs of radially structure is set in described groove.
Preferably, the described plastic spacer gross thickness for underground project waterproof plate paving extension is between 2.00-6.00mm.
This utility model solves existing pad and is difficult to form effective solder side, and pad is easily pulled out, hot melt speed is slow when welding, and after welding, pad cannot depart from splash guard, the defect such as destruction coiled material when being torn by external force.Using gasket construction of the present utility model, pad is easier to welding.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in detail.
In figure, the pad in this utility model is the pad for being welded and fixed splash guard, and it includes shim body 1, shim body 1 be provided centrally with blind hole 2, can be used in blind hole place other pad, such as metallic gasket.The bottom of blind hole 2 arranges jack 3, may be inserted into the fixtures such as nailing in jack, and the end face being provided with blind hole 2 is inclined-plane 4 or cambered surface, and inclined-plane or the cambered surface near shim body 1 edge is low spot, makes the cross section of shim body 1 generally form round table-like structure.Wherein inclined-plane and waterproof material, such as splash guard welds together, owing to using the structure on inclined-plane, there is between inclined-plane and splash guard gap, form angle, the existence of angle is equivalent to groove during welding, therefore the angle between inclined-plane and splash guard is the most much, will substantially can guarantee that having more than 1/3rd areas contacts with splash guard, when welding when, wlding is filled out between inclined-plane and splash guard, easily welding, do not result in the burn-through of splash guard, and use inclined-plane, contact area between shim body and splash guard is big, the area of welding is the biggest, therefore the adhesion between shim body and splash guard is the strongest.
The design of pad end face cambered surface, it is easier to form effective welding region in irregular construction surface with splash guard, stress point is concentrated on the welding position of pad and splash guard simultaneously.
The annular groove 5 having on the end face of jack 3 with jack 3 as the center of circle is set, the ribs 6 of radially structure is set in described groove 5.The equally distributed ribs of pad can make pad self have the highest support strength, is not susceptible to big deformation.
This utility model Intermediate gasket gross thickness is between 2.00-6.00mm.The change of size can certainly be carried out according to actual needs, the size of not limited by dimensions in this utility model.Preferably spacer thickness is more than splash guard thickness, can concentrate on pad by more heats, it is to avoid by coiled material burn-through in welding process.
The mixture that this utility model uses LDPE and thermoplastic olefin material to be formed is that current material makes pad, and pad toughness is big, and bigger deformation can occur；Pad material is compared with splash guard, and intensity is lower, pad autoclasia when by excessive external force, does not results in the damage of splash guard.
The when of use, cushion 8 is laid in preliminary bracing 7, the pad in this utility model is placed on cushion 8, afterwards metallic gasket 10 is arranged in blind hole 2, then nailing 11 is through pad and jack, hammer in preliminary bracing 7, splash guard 9 spread cushion 8 and splash guard 9, shim body 1 is between cushion 8 and splash guard 9, it should be noted that, the when of placing shim body 1, its inclined-plane 4 needs to be placed in outside, the cambered surface or the inclined-plane that make pad are relative with splash guard 9, i.e. inclined-plane 4 is to combine closely with splash guard 9, splash guard 9 is welded together by the mode finally using welding with inclined-plane 4.
These are only the preferred embodiment of this utility model embodiment; not in order to limit this utility model embodiment; within all spirit in this utility model embodiment and principle, any modification, equivalent substitution and improvement etc. made, should be included in the protection domain of this utility model embodiment.
