Description

Large cantilever arm prefabricated bent cap transportation supporting device Technical Field The utility model relates to the technical field of prefabricated bent cap support, in particular to a large cantilever prefabricated bent cap transportation support device. Background The assembled bridge has a plurality of advantages which are incomparable with the traditional bridge construction method, accords with the concepts of saving resources and protecting environment in China, and is a great trend of sustainable development of bridge construction industry in China. The whole prefabricated bent cap is large in size and difficult to transport, the prefabricated bent cap is often prefabricated in two sections in consideration of construction convenience, a cast-in-place section with the width of 2m is reserved for post-pouring, a large height difference exists between the pier top of the 1/2 prefabricated large cantilever bent cap and the cantilever end, the gravity center is easy to be unstable in the transportation process, the overturning risk exists, and the huge potential safety hazard exists. Disclosure of utility model The utility model provides a large cantilever arm prefabricated bent cap transportation supporting device which can overcome certain or certain defects in the prior art. The utility model relates to a large cantilever arm prefabricated bent cap transportation supporting device which comprises a device main body, wherein the device main body comprises a base arranged at a carriage bottom plate of a transport vehicle, a supporting component corresponding to a supporting point position of a prefabricated bent cap is arranged at the base and used for supporting the supporting point position of the prefabricated bent cap, and the top of the supporting component is matched with the gradient of the bottom surface of the bent cap. The utility model discloses a big cantilever arm prefabricated bent cap transportation strutting arrangement forms the support through supporting component to prefabricated bent cap fulcrum position, can effectively disperse the weight of bent cap, avoids the focus skew that weight concentrated led to, reduces the bent cap because of the circumstances such as rocking, jolt and take place the possibility of overturning in the transportation, has eliminated huge potential safety hazard, has ensured personnel and equipment safety in the transportation. It can be understood that through the slope matching setting of supporting component top and bent cap bottom surface for supporting component and bent cap bottom surface have bigger contact surface, have both improved the stable of being connected between supporting component and the bent cap bottom surface, can not cause the outward appearance damage yet to prefabricated bent cap. Preferably, the support assembly comprises 2 groups of bottom plates arranged at the top wall of the base, the bottom plates are vertically provided with support pipes, and top plates matched with the gradient of the bottom surface of the bent cap are formed at the top wall of the support pipes. Through along vertical setting stay tube at the bottom plate, can provide stable vertical support for prefabricated bent cap, the roof that stay tube roof department formed cooperatees with bent cap bottom surface slope for supporting component can laminate with the bent cap bottom surface, not only can provide even holding power, avoids leading to the bent cap to damage because of local atress is uneven, can also adapt to the prefabricated bent cap mound top of big cantilever and the altitude difference that exists with the cantilever end better, further improves the stability and the reliability of support.
