Technical Field
The utility model relates to a road construction's technical field, concretely relates to a connection structure for assisting link up road structure.
Background
With the rapid development of road construction in China, the construction for widening and reforming old roads is more and more, but because of the uneven new and old road foundations, longitudinal joints settled at the joints of the new and old roads are always technical problems which are difficult to thoroughly solve for a long time, and particularly for old cement concrete pavements, the joints of the new and old roads can not be well overlapped in a grading manner like asphalt concrete pavements.
In the existing road surface structure at the joint of the new road and the old road, in order to make the local repair base layer and the original road base layer be better connected into a whole, a mode of setting a bar-planting pull rod is adopted, for example, Chinese patent document (publication number is CN 203383123U) discloses a road new and old concrete plate connecting pull rod, which comprises a pull rod main body, wherein one end of the pull rod main body is an expansion head, an expansion pipe is sleeved on the pull rod main body at the end of the expansion head, a nut and a thread matched with the expansion pipe are arranged on the pull rod main body, and one end of the pull rod main body is an expansion bolt structure and is connected with the old cement concrete plate.
However, the above technical solutions still have the following technical problems: 1. although the tension rod can be stably connected with the old cement concrete plate by adopting the expansion bolt structure, the expansion bolt structure can generate stress concentration in the concrete, so that the damage probability is greatly increased, and the whole structure is unsafe; 2. when the repair base layer and the original road base layer are connected, the position of the pull rod cannot be controlled, so that the connection of the pull rod is unstable, the insufficient friction force between the pull rod and the original road base layer is also influenced, and the anti-pulling effect of the pull rod and the original road base layer is poor.
SUMMERY OF THE UTILITY MODEL
Not enough to the above that prior art exists, the utility model aims to provide a can guarantee overall structure and stabilize safety, can improve the connection structure who is used for supplementary linking up road structure of pull rod and former road basic unit's resistance to plucking effect again.
Solve the technical problem, the utility model discloses a following technical scheme:
the utility model provides a connection structure for assisting link up road structure, is including the pipe that is hollow structure, the one end of pipe is equipped with and supplies road basic unit pull rod part to stretch into the opening in the pipe, other end fixedly connected with handle, the handle with the junction of pipe is provided with vertical downwardly extending's montant, the montant inserts the interior fulcrum that forms of road basic unit, uses the opening to rotate along the horizontal plane as the centre of a circle drive pipe through the handle for the crooked circular arc that constitutes certain angle in opening position department of road basic unit pull rod that stretches into the pipe.
The beneficial effects of the utility model reside in that:
in the road renovation construction, in order to strengthen the friction force of the road base layer pull rod and the original road base layer, the pulling-resistant effect of the pull rod is better, the original road base layer is drilled, the road base layer pull rod is planted after the drilling, at the moment, the road base layer pull rod needs to be matched with the hole according to the design requirement, the utility model discloses the bending of the road base layer pull rod is changed, the circular pipe with the road base layer pull rod extending into the circular pipe is sleeved through the circular pipe with the road base layer pull rod with a hollow structure, and simultaneously, the circular pipe can reciprocate along the outer wall of the road base layer pull rod, so the design is convenient for the circular pipe to be taken out from;
the vertical rod has a supporting function for the circular tube and the handle, and simultaneously has a fulcrum function for the handle, and simultaneously, when the handle drives the circular tube to rotate along the horizontal plane, the vertical rod can also rotate along with the circular tube, so that the height direction of the circular tube is kept unchanged in the moving process, and the stability of the circular tube in the height direction is kept;
during operation, an operator only needs to hold the handle and drive the circular tube to rotate to a certain angle along a horizontal plane by taking the opening part as a circle center, at the moment, the road base layer pull rod extending into the circular tube is bent at the opening part and forms a certain-angle bend with the road base layer pull rod which does not extend into the circular tube, so that the road base layer pull rod is better fastened with a hole preset in the original road base layer process, the friction force between the road base layer pull rod and the original road base layer is increased, and the anti-pulling effect is improved.
Furthermore, a plurality of through holes are uniformly distributed in the round pipe along the length direction, and the position of the road base layer pull rod extending into the round pipe is observed through the through holes. Whether the bending size of the road base layer pull rod meets the process requirements can be judged.
