Description
Technical Field
The utility model relates to a fishback telescoping device especially relates to a height-adjustable's fishback telescoping device.
Background
The expansion joint is a structural joint which is arranged for preventing the structure of a building component from cracking or being damaged due to the change of the weather temperature (thermal expansion and cold contraction), a comb plate expansion device needs to be installed at the structural joint for ensuring the safety of personnel and driving, and the position where the comb plate expansion device is installed is a reserved groove opening of a beam body. In the conventional installation process, after the beam body structure is installed, the reserved notch is filled with temporary fillers, and an asphalt layer with a certain thickness is paved on the surface of the whole beam body. After the asphalt layer is paved, the temporary filler at the reserved groove opening and the asphalt layer above the groove opening are broken, the installation of the expansion joint can be carried out only after the asphalt layer is paved, and the engineering is about to complete the formal vehicle communication after the asphalt layer is paved, so that the installation period of the expansion joint is short, the engineering can be completed only by driving or prolonging the period, and the progress plan of the whole engineering is influenced.
Disclosure of Invention
The utility model aims to solve the technical problem that a height-adjustable's fishback telescoping device that can install before pitch is mated formation is provided.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a height-adjustable's fishback telescoping device, includes two fishbacks that mutually support and use, still including being used for supporting a plurality of roots of fishback be parallel to each other's channel-section steel, the channel-section steel follow fishback length direction distribute, the upper surface outside welding of channel-section steel have an anticollision baffle, the bottom welding of channel-section steel have two threaded sleeves, the lateral wall and the beam-ends embedded steel bar of channel-section steel be connected, fishback's lower surface be provided with and transfer high level, the fishback with the channel-section steel between pass through bolted connection, the bolt from the top down pass in proper order the fishback transfer high level the channel-section steel with threaded sleeve.
The inner side of the anti-collision baffle plate is connected with the outer side of the comb plate through reinforcing ribs in a welded mode. In the vehicle impact process, the collision baffle is easy to have unstable conditions, so that a mode of welding reinforcing ribs is adopted, the strength is increased, and the impact is resisted.
The bottom inside portion welding of channel-section steel have C shaped steel, two the fishback between be provided with V type waterstop, the both ends of V type waterstop inlay respectively the C shaped steel in. Adopt the mode of C shaped steel formula chucking, the leakproofness is better, avoids conventional waterstop to adopt the tight mode of couple clamp, the easy problem of leaking of appearing.
Compared with the prior art, the utility model has the advantages of: the utility model relates to a fishback telescoping device, it welds the threaded sleeve in the channel-section steel bottom, forms the welding subassembly with the anticollision baffle welding at the channel-section steel upper surface, before pitch is mated formation, according to the design height of pitch, selects the anticollision baffle of suitable height and the height-adjusting layer of suitable height, makes the upper surface of fishback telescoping device and the highly uniform of the upper surface on design pitch layer, treats the telescoping device installation back that finishes, paves the pitch layer again. Certain error can exist in the asphalt layer paving process, so the bolt fastening mode downwards is adopted, the height of the fastening screw can be finely adjusted, and the height can also be finely adjusted by selecting a height-adjusting layer with proper height. The height adjusting layer is an assembly of rubber wrapped steel plates, the steel plates at the bottom enable the height adjusting layer to have certain pressure resistance, and the rubber enables the height adjusting layer to be in flexible contact with the comb plate and has a function of a certain horizontal corner.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
The utility model provides a height-adjustable's fishback telescoping device, as shown in fig. 1 and fig. 2, including two fishback 1 that mutually support and use, still including the channel-section steel 2 that a plurality of roots that are used for supporting fishback 1 are parallel to each other, channel-section steel 2 distributes along fishback 1 length direction, the outer lateral part welding of upper surface of channel-section steel 2 has anticollision baffle 3, the bottom welding of channel-section steel 2 has two threaded sleeve 4, the lateral wall and the girder end embedded steel bar 5 of channel-section steel 2 are connected, fishback 1's lower surface is provided with transfers high layer 6, be connected through bolt 7 between fishback 1 and the channel-section steel 2, bolt 7 from the top down passes fishback 1 in proper order, transfer high layer 6, channel-section steel 2 passes through threaded connection with.
In this embodiment, the inner side of the crash barrier 3 and the outer side of the comb plate 1 are welded and connected by the reinforcing rib 8. C shaped steel 9 is welded to the bottom inside portion of channel-section steel 2, is provided with V type waterstop 10 between two fishback 1, and the both ends of V type waterstop 10 inlay card respectively in C shaped steel 9.
The above embodiments are further illustrative of the present invention, but the scope of the present invention is subject to the claims.
