Description
Technical field
This utility model belongs to Highway bridge technique field, particularly relates to a kind of shallow embedding formula bridge extension joint.
Background technology
The retractor device of highway bridge mainly uses two kinds of technology, and one is barrier type modulus retractor device, and another kind is
Single support beam type retractor device, in the prior art, the expansion joint of bridge may cause expansion joint notch the most shallow because of construction problem,
Causing maurer expansion seal to install, it is impossible to meet the telescopic displacement amount of Bridge Design, cause increasing workload, raising is constructed into
This.
Therefore, professional and technical personnel in the field's technical problem in the urgent need to address is exactly, the proposition how to innovate
A kind of device, when bridge construction, during if it occur that bridge expanssion joint notch is crossed shallow, can continue to install large displacement expansion joint
Problem.
Utility model content
For solving the problems referred to above, the utility model discloses a kind of shallow embedding formula bridge extension joint, including: " king " font
Steel, support beam, bridge main body, polylith fix lip block, polylith sliding support cushion block, and described " king " shaped steel embeds described
Inside support beam, the whole height of support beam and " king " shaped steel is not more than 18 centimetres, and the expansion joint notch of described bridge main body is big
In 23 centimetres, described support beam fixes lip block by described polylith, polylith sliding support cushion block is fixed on described bridge main
Inside the expansion joint of body, described polylith is fixed lip block and is positioned at the above two ends of support beam, described polylith sliding support cushion block
It is positioned at two ends below support beam.
Further, described " king " shaped steel is fixed by welding manner with support beam.
Further, described polylith fixes lip block, polylith sliding support cushion block is made up of rubber.
Further, described bridge main body is made up of steel fibre concrete.
Compared with prior art, this utility model has the advantage that
The mode that this utility model have employed in " king " shaped steel embeds support beam and is welded and fixed, reduces overall high
Degree, solves contingent bridge expanssion joint notch in engineering construction the most shallow, it is impossible to the problem installing large displacement expansion joint, with
Time make bridge have driving steadily, advantage that noise is little.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing used in description of the prior art does one and introduces simply.
Fig. 1 is the structural representation of a kind of shallow embedding formula bridge extension joint of the present utility model.
In figure: 1 " king " shaped steel, 2 support beams, 3 bridge main bodies, 4 polyliths fix lip block, 5 polylith sliding support pads
Block.
Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, new below in conjunction with this practicality
Accompanying drawing in type embodiment, is clearly and completely described the technical scheme in this utility model embodiment, it is clear that retouched
The embodiment stated is only a part of embodiment of this utility model rather than whole embodiments.Based in this utility model
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, all
Belong to the scope of this utility model protection.
As it is shown in figure 1, a kind of shallow embedding formula bridge extension joint.Including: " king " shaped steel 1, support beam 2, bridge main body 3,
Polylith fixes lip block 4, polylith sliding support cushion block 5, and it is internal that described " king " shaped steel 1 embeds described support beam 2, support beam
2 and the whole height of " king " shaped steel 1 be not more than 18 centimetres, the expansion joint notch of described bridge main body 3 is more than 23 centimetres, described
Support beam 2 fixes lip block 4 by described polylith, polylith slidably supports cushion block 5 and is fixed on the expansion joint of described bridge main body 3
Inside, described polylith fixes lip block 4 and is positioned at the above two ends of support beam 2, and described polylith sliding support cushion block 5 is positioned at support
Two ends below beam 2.
Described " king " shaped steel 1 is fixed by welding manner with support beam 2.
Described polylith fixes lip block 4, polylith sliding support cushion block 5 is made up of rubber.
Described bridge main body 3 is made up of steel fibre concrete.
In bridge construction process, due to technology and equipment reason, inevitably there is bridge expanssion joint notch mistake
Shallow problem, the most shallow Maurer expansion installation that directly results in of bridge expanssion joint notch cannot install, telescopic displacement during Bridge Design
Amount can not meet, and owing to the whole height of Maurer expansion installation is at 28 centimetres, it requires that bridge expanssion joint notch height is more than
33 centimetres, under prior art conditions, the height of the bridge expanssion joint notch situation less than 33 centimetres happens occasionally.Prior art
It is the mode above support beam 2 that " king " shaped steel 1 is arranged on, and shallow embedding formula bridge extension joint have employed " king " shaped steel 1
Embedding the frame mode of support beam, therefore, the whole height of shallow embedding formula bridge extension joint is not more than 18 centimetres, it is possible to meet bridge
The installation more than 23 centimetres of the beam expansion joint notch, therefore, it is possible to adapt to more complicated construction condition.
Above a kind of shallow embedding formula bridge extension joint provided by the utility model is described in detail, herein should
Being set forth principle of the present utility model and embodiment by specific case, the explanation of above example is only intended to side
Assistant solves method of the present utility model and core concept thereof；Simultaneously for one of ordinary skill in the art, new according to this practicality
The thought of type, the most all will change, and in sum, this specification content should not be managed
Solve as to restriction of the present utility model.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, it is not limited to this
Utility model, although being described in detail this utility model with reference to previous embodiment, for those skilled in the art
For, the technical scheme described in foregoing embodiments still can be modified by it, or to wherein portion of techniques feature
Carry out equivalent, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
Within protection domain of the present utility model should be included in.
