Abstract
The utility model discloses a member connecting structure. The utility model is characterized in that one pipe sleeve is beforehand buried and at least one hole is beforehand retained on a concrete slab. In the utility model, because the one pipe sleeve is beforehand buried and at least the one hole is beforehand retained on a concrete slab, a shear pin is arranged in the beforehand buried sleeve for bearing vertical load, and a high strength bolt is arranged in the beforehand retained hole for fixing a steel bracket; certain pretightening force is exerted to the high strength bolt, can fix the steel bracket, can be favorable to the friction force of a steel plate and concrete, increases shear resistant safety reserve of the shear pin, and does not influence the bridge structure; the installation is convenient, the steel bracket can be replaced, formerly beforehand retained steels on the concrete slab is omitted, and simultaneously, a main structure has no corrosive channel and the corrosion problem can be effectively solved.
Description
Technical field:
The utility model relates to the technical field of steel and concrete syndeton, a kind of specifically syndeton of shelving that is used for platforms such as pipeline passway.
Background technology:
At present, as in the engineering designs over strait such as water delivery, cable, adopt the seabed comb at pipeline, but constructional difficulties, the expense height, these pipelines can depend on bridge and lay, and at bridge case beam sides the pipeline passway platform are set, this platform is fixed on case beam concrete slab, also claim on the web that its connected mode usually adopts pre-embedded steel slab on web, later stage weldable steel bracket or directly on web, do the concrete bracket and support the pipeline access platform.But in the Yu Haiyang environment of engineering department over strait, the requirement for anticorrosion height corrosion passage occurs for preventing the bridge main structure, erodes to reinforcing bar, influences bridge structure safe, and bridge does not allow pre-embedded steel slab on the case beam, as does the concrete bracket and then influenced the bridge slding form operation.
Summary of the invention:
The purpose of this utility model provides a kind of member syndeton, and it can overcome some shortcomings of the prior art, does not influence bridge construction, can prevent that the corrosion passage from appearring in the bridge main structure, solves etching problem.
To achieve these goals, the technical solution of the utility model is: a kind of member syndeton, it mainly comprises concrete slab, and the steel corbel with concrete slab links into an integrated entity is characterized in that: at the pre-buried pipe box of concrete slab with reserve a hole at least.
The utility model is because at the pre-buried pipe box of concrete slab with reserve a hole at least, shear pin is set in service sleeve bears vertical load, fixedly steel corbel of high-strength bolt is set in reserving hole, high-strength bolt is applied certain pretightning force, both fixing steel corbels, can be beneficial to its steel plate and concrete frictional force again, increase the shearing resistance safety stock of shear pin, and do not influence bridge construction, simple installation, steel corbel is replaceable, save original on concrete slab in the pre-buried steel, main structure does not have the corrosion passage, can solve etching problem effectively.
Description of drawings:
Fig. 1 is the structural representation of the utility model one embodiment
Fig. 2 is the A-A view of Fig. 1
Fig. 3 is for using pipeline passway platform schematic diagram of the present utility model
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is further described.
The utility model mainly comprises concrete slab 1, concrete slab is generally web or stomach wall, the steel corbel 2 that links into an integrated entity with concrete slab 1, it is characterized in that: at concrete slab 1 a pre-buried pipe box 3 with reserve a hole 4 at least, shear pin 5 is set in pipe box 3 in the enforcement, bolt 6 is set in reserving hole 4, bolt is for applying the high-strength bolt of pretightning force, present embodiment is provided with shear pin in pipe box, reserve two holes at concrete slab, in each hole, high-strength bolt is set, adopt a shear pin to bear vertical load, two high-strength bolts are steel corbel fixedly, and the gap between shear pin and the service sleeve can reach the 1-2 millimeter, gap between high-strength bolt and the preformed hole is generally 5 millimeters, high-strength bolt applies certain pretightning force, and both fixing steel corbels can utilize the steel plate and the concrete frictional force of steel corbel again, increase the shearing resistance safety stock of shear pin, the mark 7 in the accompanying drawing is the pipeline passway platform.
Claims (3)
1, a kind of member syndeton, it mainly comprises concrete slab, the steel corbel with concrete slab links into an integrated entity is characterized in that: at the pre-buried pipe box of concrete slab with reserve a hole at least.
