Technical Field
The utility model relates to a temporary fixing structure of a prefabricated pier column and a bearing platform, and belongs to the technical field of bridge and culvert engineering.
Background
The prefabricated bridge pier consists of a capping beam and a pier column, and is connected by adopting a prestress steel beam. The assembly process comprises the following steps: and pre-burying the pre-stressed steel beam anchoring end in the bearing platform, enabling the tensioning end to pass through pre-stressed pore channels in the pier column and the capping beam, and tensioning pre-stress at the top of the capping beam after pre-assembling the pier column and the capping beam is completed, so that the installation of the prefabricated pier is completed. Epoxy sealant is smeared between the capping beam, the pier stud and the bearing platform.
The connection of pier column and cushion cap top is the key point of assembling, specifically does: (1) the surface flatness accuracy of the joint surface is required to be extremely high. (2) After the initial installation of the pier column is finished, the verticality of the pier column needs to be finely adjusted, and the pier column is ensured to be vertical. (3) The pier stud is temporarily fixed, so that engineering accidents caused by the overturning of the pier stud are prevented, and constructors are injured.
Disclosure of Invention
The utility model aims to provide a temporary fixing structure for a prefabricated pier stud and a bearing platform, which can prevent the junction of the prefabricated pier stud and the top surface of the bearing platform from overturning and ensure construction safety.
The technical scheme adopted by the utility model for achieving the purpose is as follows: the temporary fixing structure comprises a prefabricated pier, a bearing platform, anchor bolt sleeve reinforcing steel bars, bearing platform inner anchor bolt sleeves, pier inner anchor bolt sleeves, bolts, bracket and bearing platform contact surface steel plates, bracket and pier contact surface steel plates and bracket main steel plates, wherein the anchor bolt sleeve reinforcing steel bars are respectively arranged in a groined shape and are connected with pier steel bars of the prefabricated pier and steel bars in the bearing platform, the bearing platform inner anchor bolt sleeves are vertically embedded in the bearing platform, and the pier inner anchor bolt sleeves are horizontally embedded in the pier of the prefabricated pier; the steel bracket is manufactured by welding the steel plate at the contact surface of the bracket and the bearing platform, the steel plate at the contact surface of the bracket and the pier column and the main steel plate of the bracket vertically; the bolts penetrate through the steel plate of the contact surface of the bracket and the bearing platform to be connected with the anchor bolt sleeve in the bearing platform, and the bolts penetrate through the steel plate of the contact surface of the bracket and the pier column to be connected with the anchor bolt sleeve in the pier column; the structure is divided into four groups which are uniformly distributed around the prefabricated bridge pier to temporarily fix the prefabricated bridge pier and the bearing platform together.
According to the utility model, the anchor bolt sleeve reinforcing steel bars are arranged to locally reinforce the concrete at the reserved bolt sleeve sides of the pier column and the bearing platform. Through setting up the bolt sleeve of inner wall tapping, be favorable to bolt and bolt sleeve to connect as wholly, transmit the anchoring force to the steel corbel. Through setting up the steel bracket, carry out effective anchor to prefabricated assembly formula pier stud. Through setting up the bolt, correct the straightness that hangs down of prefabricated assembly pier through adjusting bolt.
