Description
Technical field
The utility model relates to field of bridge construction, is specifically related to a kind of bridge expanssion joint end liner support nail and has its bridge.
Background technology
Generally all polyurethane elastomer can be cast with in current railroad bridge shrinkage joint.When using polyurethane elastomer to carry out casting and constructing, generally end liner can be set between two bridge plates, and then cast urethane elastomer.But, when constructing, due to the effect of self gravitation, easily there is end liner entirety and subsiding, causing initial failure, thus have influence on the quality of bridge.
Utility model content:
In view of this, the utility model aims to provide and a kind ofly can support the bridge expanssion joint end liner support nail that end liner makes it subside and the bridge with this bridge expanssion joint end liner support nail.
In order to realize the purpose of this utility model, the utility model provides a kind of bridge expanssion joint end liner support nail on the one hand, it comprises the female nail of support, locking nut and supports male nail, the tail end of the described tail end and the male nail of described support that support mother's nail is threaded connection, described locking nut is at described support mother nail and describedly supports between male nail, and follows closely be threaded with the described public affairs that support.
Preferably, the described tail end supporting public nail is provided with screw rod, and the tail end of described support mother nail is provided with screw, described screw rod and described screw threaded engagement.
Preferably, the axis of the described support head end center of male nail and the female head end center of following closely of described support and described screw rod is located along the same line.
Preferably, described support public affairs nail on and are provided with the first pulling part, and described support mother nails on and is provided with the second pulling part.
Due to the setting of bridge expanssion joint end liner support nail, can prevent end liner from subsiding, thus guarantee production friendship phase and quality.
The utility model provides a kind of bridge on the other hand, it comprises the first adjacent bridge plate and second axle plate, bridge expanssion joint is formed between described first bridge plate and second axle plate, it is characterized in that, shrinkage joint end liner and the bridge expanssion joint end liner support nail according to above-mentioned any embodiment is provided with between described bridge expanssion joint, the described mother's of support nail inserts the described first bridge plate side relative with described bridge expanssion joint, the described public affairs nail that supports inserts the described second axle plate side relative with described bridge expanssion joint, described shrinkage joint end liner is supported on described bridge expanssion joint end liner support nail.The bridge that the utility model embodiment provides obviously also has the beneficial effect that above-mentioned bridge expanssion joint end liner support nail brings, and repeats no more herein.
accompanying drawing illustrates:
Fig. 1 is the structural representation of the bridge expanssion joint end liner support nail that the utility model embodiment provides.
detailed description of the invention:
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Please refer to Fig. 1, the utility model embodiment provides a kind of bridge expanssion joint end liner support nail, and it comprises the female nail 1 of support, locking nut 3 and supports male nail 2.The tail end supporting female nail 1 and the tail end supporting male nail 2 are threaded connection, and the distance supported between female nail 1 and the head end supporting male nail 2 is regulated by helical rotation between the two.Locking nut 3 is at the female nail 1 of support and support and malely follow closely between 2, follow closely 2 and is threaded, and only support the tail end supporting female nail 1 with support is public, gets loose to prevent from supporting male 2 tail ends following closely 1 from support mother of following closely.
In a preferred embodiment, the tail end supporting public nail 2 is provided with screw rod 21, and the tail end supporting female nail 1 is provided with screw, screw rod 21 and screw threaded engagement, thus makes the male nail 2 of support and support female nail 1 to link together.
In the present embodiment, the head end supporting male nail 2 and the head end supporting female nail 1 are the tip of taper.In a preferred embodiment, the head end center supporting male nail 2 is located along the same line with support female nail head end center of 1 and the axis of screw rod 21, so arranges and can make the stressed more balanced of this bridge expanssion joint end liner support nail, is not easy to damage.
In a preferred embodiment, support on public nail 2 and be provided with the first pulling part 22, support on female nail 1 and be provided with the second pulling part 11, the first pulling part 22 or the second pulling part 11 can be pulled by spanner, make the male nail 2 of support and support mother follow closely 1 between relative motion.
During construction, first this bridge expanssion joint end liner support nail is put between bridge expanssion joint, then the first pulling part 22 or the second pulling part 11 is pulled with spanner, make the male nail 2 of support and support female follow closely 1 between relative motion, the head end of the male nail 2 of support and the female nail 1 of support is made to penetrate the side of the bridge plate of bridge expanssion joint both sides, then lock locking nut 3, prevent supporting public nail 2 and get loose.Then end liner is set above bridge expanssion joint end liner support nail, and builds.Due to the setting of bridge expanssion joint end liner support nail, can prevent end liner from subsiding, thus guarantee production friendship phase and quality.
The utility model embodiment also provides a kind of bridge on the other hand, it comprises the first adjacent bridge plate and second axle plate (not shown), be formed with bridge expanssion joint between first bridge plate and second axle plate, between bridge expanssion joint, be provided with shrinkage joint end liner and the bridge expanssion joint end liner support nail according to above-mentioned any embodiment.Support the side that female nail 1 first bridge plate is relative with bridge expanssion joint, support public nail 2 and insert the second axle plate side relative with bridge expanssion joint, shrinkage joint end liner is supported on bridge expanssion joint end liner support nail.The bridge that the utility model embodiment provides obviously also has the beneficial effect that above-mentioned bridge expanssion joint end liner support nail brings, and repeats no more herein.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
