Abstract
The utility model discloses a type of nai time expansion joint device is used to bridge, including first boundary beam, second boundary beam, first dowel, second dowel and foamed plastic board, first dowel install on the left side limit of first boundary beam and extend to the bottom of first boundary beam, the second dowel install on the right side limit of second boundary beam and extend to the bottom of second boundary beam, first boundary beam and second boundary beam between be provided with certain clearance, the foamed plastic board install between the clearance of first boundary beam and second boundary beam. In this way, the utility model provides a type of nai time expansion joint device is used to bridge, the sound construction, long service life, safety when both guaranteeing the atress, it is even to reach the displacement again, very favourable to big displacement volume telescoping device, has practiced thrift steel.
Description
Technical field
The utility model relate to bridge member etc. field, particularly relate to a kind of bridge weather resistant expansion gap device.
Background technology
Along with the height of temperature changes, because the principle of expanding with heat and contract with cold, the length of bridge also can change thereupon, thus causes bridge end to produce displacement, smooth-going in order to ensure driving, must arrange bridge expansion joint installation.Bridge extension joint is position the weakest in bridge construction, directly bears the repeated action of vehicular load, is also easily subject to the impact of various nature or extraneous factor simultaneously, is easy to be damaged.
Current bridge extension joint is generally direct by embedded bar and shrinkage joint welding, play fixation, but in this structure, after welding, long-term existence tensile stress between reinforcing bar and stretching device, application life is short.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of bridge weather resistant expansion gap device, sound construction, long service life, safety when both ensureing stressed, can reach again displacement even, highly beneficial to Large Displacement Expansion Joints, has saved steel.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of bridge weather resistant expansion gap device, comprise the first side bar, second side bar, first dowel, second dowel and plastic foamboard, the first described dowel is arranged on the limit, left side of the first side bar and extends to the bottom of the first side bar, the second described dowel is arranged on the right edge of the second side bar and extends to the bottom of the second side bar, certain gap is provided with between the first described side bar and the second side bar, described plastic foamboard is arranged between the gap of the first side bar and the second side bar.
In the utility model preferred embodiment, described weather resistant expansion gap device also comprises the first rubber sealing block and the second rubber sealing block, and the first described rubber sealing block and the second rubber sealing block are separately positioned on the first side bar and the second side bar front port and fit tightly with plastic foamboard.
In the utility model preferred embodiment, the first described dowel and the material of the second dowel are steel.
The beneficial effects of the utility model are: bridge weather resistant expansion gap device of the present utility model, sound construction, long service life, safety when both ensureing stressed, can reach again displacement even, highly beneficial to Large Displacement Expansion Joints, have saved steel.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the side sectional view of a preferred embodiment of the utility model bridge weather resistant expansion gap device;
Reference numeral is as follows: 1, the first side bar, the 2, second side bar, the 3, first dowel, the 4, second dowel, and 5, plastic foamboard, the 6, first rubber sealing block, the 7, second rubber sealing block.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model embodiment comprises:
A kind of bridge weather resistant expansion gap device, comprise the first side bar 1, second side bar 2, first dowel 3, second dowel 4 and plastic foamboard 5, the first described dowel 3 is arranged on the limit, left side of the first side bar 1 and extends to the bottom of the first side bar 1, the second described dowel 3 is arranged on the right edge of the second side bar 2 and extends to the bottom of the second side bar 2, be provided with certain gap between the first described side bar 1 and the second side bar 2, described plastic foamboard 5 is arranged between the first side bar 1 and the gap of the second side bar 2.
In above-mentioned, described weather resistant expansion gap device also comprises the first rubber sealing block 6 and the second rubber sealing block 7, and the first described rubber sealing block 6 and the second rubber sealing block 7 are separately positioned on the first side bar 1 and the second side bar 2 front port and fit tightly with plastic foamboard 5.
Further, the first described dowel 3 and the material of the second dowel 4 are steel.
In sum, bridge weather resistant expansion gap device of the present utility model, sound construction, long service life, safety when both ensureing stressed, can reach again displacement even, highly beneficial to Large Displacement Expansion Joints, has saved steel.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
