SUMMERY OF THE UTILITY MODEL
Aiming at the problems, the utility model designs a splicing combined comb plate seam which is safe, stable and good in damping effect.
In order to solve the technical problems, the technical scheme adopted by the utility model is as follows:
the utility model provides a concatenation combination formula broach board seam, includes broach board base, fixed broach board, activity broach board, the broach board base is equipped with two, is located the lower part of fixed broach board, activity broach board respectively, all be equipped with spring base in the broach board base, be equipped with the spring on the spring base respectively, be equipped with first reinforcing bar between spring and the broach board base, one side that the broach was kept away from to fixed broach board, activity broach board all is equipped with the second reinforcing bar, be equipped with the pitch layer on fixed broach board, the activity broach board.
The technical scheme of the utility model is further improved as follows: and a water stop belt is arranged between the two adjacent comb plate bases.
The technical scheme of the utility model is further improved as follows: the waterstop is connected with the comb plate bases on the two sides through cross screws.
The technical scheme of the utility model is further improved as follows: the comb plate base is of a right-angle structure.
The technical scheme of the utility model is further improved as follows: the asphalt layer is level with the highest positions of the fixed comb plate and the movable comb plate.
Due to the adoption of the technical scheme, the utility model has the technical progress that:
the spliced combined comb plate seam is convenient to use and easy to maintain, and the spring base, the spring and the first steel bar which are arranged at the lower part of the comb plate base can slow down the vibration of the comb plate seam caused by the overweight of a vehicle-mounted load; the second reinforcing steel bars are used for limiting the fixed comb plate and the movable comb plate, so that the fixed comb plate and the movable comb plate are more stable; the waterstop that is equipped with between two adjacent fishback bases is convenient for carry out the separation to the rainwater, prevents that whole device from receiving the rainwater erosion, prolongs the life of fishback seam.

FIG. 2 is a schematic front structural view of a spliced combined comb plate seam according to the utility model.
The figure shows that the steel plate comprises 1-a comb plate base, 2-a spring base, 3-a spring, 4-first steel bars, 5-second steel bars, 6-a fixed comb plate, 7-a movable comb plate, 8-a cross screw, 9-a water stop and 10-a pitch layer.
Detailed Description
The present invention is further described in detail below with reference to examples so that those skilled in the art can practice the utility model with reference to the description.
The first embodiment:
as shown in fig. 1-2, a spliced combined comb plate seam comprises a comb plate base 1, two fixed comb plates 6 and two movable comb plates 7, wherein the two comb plate bases 1 are respectively located at the lower parts of the fixed comb plates 6 and the movable comb plates 7 and play roles of supporting the fixed comb plates 6 and the movable comb plates 7; spring bases 2 are arranged in the comb plate bases 1, springs 3 are arranged on the spring bases 2 respectively, and the spring bases 2 are used for fixing the springs 3; a first reinforcing steel bar 4 is arranged between the spring 3 and the comb plate base 1, the first reinforcing steel bar 4 plays a role in connecting the comb plate base 1 and the spring 3, and when a heavy vehicle passes through a comb plate seam, vibration caused by overload of the vehicle can be buffered; second reinforcing steel bars 5 are arranged on the sides, far away from the comb teeth, of the fixed comb plate 6 and the movable comb plate 7, and the second reinforcing steel bars 5 are embedded into concrete to reinforce the fixed comb plate 6 and the movable comb plate 7; be equipped with pitch layer 10 on fixed fishback 6, the activity fishback 7, pitch layer 10 covers in the lower one side of fixed fishback 6, activity fishback 7, further reinforces fixed fishback 6, activity fishback 7.
Second embodiment:
on the basis of the first embodiment, a water stop belt 9 is arranged between every two adjacent comb plate bases 1, so that dust and rainwater can be prevented from corroding the comb plate seams; the water stop belt 9 is connected with the comb plate bases 1 on the two sides through the cross screws 8, so that the assembly and disassembly are more convenient; the comb plate base 1 is of a right-angle structure, and a space is reserved for damping of a spring 3 at the bottom; the asphalt layer 10 is level with the highest positions of the fixed comb plate 6 and the movable comb plate 7, so that the smoothness of the road surface is ensured, and pedestrians and vehicles can run more safely.
When the water stop device is used, firstly, the spring base 2, the spring 3 and the first reinforcing steel bar 4 are embedded in advance, then the two comb plate bases 1 are erected on the upper portion of the first reinforcing steel bar 4 respectively, the water stop belt 9 is installed in the middle of the comb plate bases 1 through the cross screws 8, finally, the fixed comb plate 6 and the movable comb plate 7 connected with the second reinforcing steel bar 5 are paved between the two comb plate bases 1 respectively, the asphalt layer 10 is paved for use, and when the comb plate is sewn with damages, only the damaged parts can be replaced.
Compared with an integrated structure, the spliced combined comb plate seam is more flexible, convenient to maintain, safe and stable, has a good damping effect, prolongs the service life of the comb plate seam, ensures the life safety of people, and is more suitable for production and life.
