SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a magnetic force of making an uproar fishback telescoping device falls that machining efficiency is high, simple to operate, factor of safety are high, the construction is simple, the time limit for a project shortens.
In order to solve the above problem, the utility model discloses the technical scheme that magnetic force falls the comb plate telescoping device of making an uproar adopts does: including fishback, stagnant water structure and pre-buried door style of calligraphy reinforcing bar the fishback below is provided with the fixed anchor board together with this fishback be provided with horizontal locating hole on the anchor board, the up end of locating hole with the lower terminal surface of pre-buried door style of calligraphy reinforcing bar upper ledge is on a water flat line the locating hole with penetrate horizontal reinforcing bar in the pre-buried door style of calligraphy reinforcing bar, horizontal reinforcing bar and anchor board and pre-buried door style of calligraphy reinforcing bar pass through welded fastening and are in the same place.
The additional technical characteristics are as follows:
the positioning holes are two or more circular positioning holes which are mutually independent in the horizontal direction;
the positioning hole is a rectangular positioning hole;
an embedded metal block is arranged below the comb plate, and a magnetic block is fixed on the lower surface of the comb plate at a position corresponding to the embedded metal block.
The utility model provides a magnetic force is fallen comb plate telescoping device of making an uproar compares with prior art, has following advantage: firstly, because the comb plate comprises the comb plate, the water stop structure and the pre-buried door-shaped steel bars, the anchoring plate fixed with the comb plate is arranged below the comb plate, the anchoring plate is provided with the transverse positioning hole, the upper end surface of the positioning hole and the lower end surface of the upper frame of the pre-buried door-shaped steel bars are on the same horizontal line, the transverse steel bars penetrate into the positioning hole and the pre-buried door-shaped steel bars, the transverse steel bars, the anchoring plate and the pre-buried door-shaped steel bars are fixed together by welding, before concrete construction, the pre-buried door-shaped steel bars are firstly pre-buried in concrete, the comb plate with the anchoring plate is placed above the pre-buried door-shaped steel bars, so that the anchoring plate is attached to the side surface of the pre-buried door-shaped steel bars, the transverse steel bars penetrate through the positioning hole and the pre-buried door-shaped steel bars, and then the transverse steel bars, the anchoring plate and the pre-buried, the material has strong impact resistance, is simpler to process and install, is easy to construct, and greatly shortens the construction period; secondly, the positioning holes are two or more circular positioning holes which are mutually independent in the horizontal direction, a transverse steel bar is inserted into each positioning hole, and two or more transverse steel bars are arranged in one embedded portal steel bar, so that the structure is firmer; thirdly, as the positioning hole is a rectangular positioning hole, the transverse reinforcing steel bars are arranged in the rectangular positioning hole side by side, and the transverse reinforcing steel bars, the anchoring plate and the embedded door-shaped reinforcing steel bars are welded together, the structure is firmer, the impact resistance is stronger, and the stability is better; and fourthly, because the fishback below is provided with embedded metal piece the fishback with the lower fixed surface that embedded metal piece corresponds the position has the magnetic force piece, can transmit the vibrations energy when the vehicle passes through well, noise greatly reduced.
