Abstract
The utility model discloses a claw-type connecting piece which comprises a base plate, wherein the base plate is of a cross shape; the end surface on one side of the base plate is provided with nail teeth; and the nail teeth are uniformly distributed along the edge of the base plate. The claw-type connecting piece can be used for tightly connecting EPS (expandable polystyrene) block bodies together, plays a role of fixing the position relationships among the EPS block bodies on a panel and also among the upper and lower EPS block bodies, can reduce subgrade settlement quantity and further reduce the difference settlement between a bridge platform and an embankment on the back side of the platform so as to realize the stable transition of the settlement of the transition section between a road and a bridge, thus being very effective in preventing and treating the damage of bumping at bridge-head.
Description
Technical field
The utility model relates to a kind of pawl type connecting piece.
Background technology
Reaching the bridge site district along the line at road is typical soft foundation.Because abutment adopts pile foundation, its soft foundation under various load long terms, big relatively many of primary consolidation, secondary consolidation settlement amount; Distortion is obviously inharmonious between the two; After being open to traffic, will produce bumping at bridge-head phenomenon in various degree, badly influence road speed and safety, and cause having to repair continually; Cause local current the interruption, also increased maintenance cost behind the worker simultaneously significantly.In order to reduce relative settlement behind the abutment of the Xinhe River, river in Zhejiang Province, control bumping at bridge-head disease, the abutment platform back of the body adopts the EPS light road bank in two sides.
Summary of the invention
The purpose of the utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of structure simple, can be with close-fitting a kind of pawl type connecting piece between the EPS block.
The utility model is realized through following technical scheme:
A kind of pawl type connecting piece includes substrate, and said substrate is a cross shape, and the end face of substrate one side is provided with spike-tooth, and spike-tooth evenly distributes along the inboard of substrate edges.
The end face of said substrate opposite side is provided with spike-tooth, and spike-tooth evenly distributes along the inboard of substrate edges.
The utility model has the advantages that: the utility model can be with closely linking together between the EPS block; And can play and be fixed between the EPS block on the plane; Also can fix the relation of the position between the EPS block up and down, and can reduce the subgrade settlement amount, and then reduce the relative settlement of abutment and platform back of the body embankment; Realizing the smooth transition of road-bridge transition section sedimentation, is highly effective for control bumping at bridge-head disease.
