一种无轨挂篮施工用后锚结构

Abstract

本实用新型公开了一种无轨挂篮施工用后锚结构，涉及桥梁挂篮施工技术领域，包括多个承重梁，多个所述承重梁平行设置于已完成浇筑施工桥体上，所述承重梁用于对桥体施工模板进行承重支撑；多个加强框；多个加强杆；多个锚固行走组件。本实用新型让所述锚固行走组件可跟随承重梁的工作状态进行调整。也即在需要让承重梁进行行走时，锚固行走组件将桥体与承重梁通过锚固部进行锚固解除，同时让行走部配合承重梁进行行走；在需要锚固时，锚固行走组件通过锚固部将承重梁与桥体进行锚固锁定。即有效的实现解决现有技术中存在传统挂篮行走容易与锚固结构出现干扰的缺点。

Claims

A post anchor structure for a trackless trolley construction, characterized by, include: Multiple load-bearing beams are arranged in parallel on the completed bridge body, and the load-bearing beams are used to support the bridge body construction formwork. Multiple reinforcing frames are disposed between pairs of adjacent load-bearing beams, and the reinforcing frames are used to connect the pairs of adjacent load-bearing beams together as a whole. Multiple reinforcing rods are symmetrically arranged in pairs on both sides of the load-bearing beam. The reinforcing rods are used to enhance the overall support strength of the load-bearing beam and the reinforcing frame. Multiple anchoring and traveling components, the anchoring and traveling components including: An anchorage is provided on the load-bearing beam and is located on the bridge body that has been poured. One end of the anchorage is sleeved on the load-bearing beam, and the other end of the anchorage passes through the bridge body that has been poured and is anchored to the bridge body that has been poured. The traveling section is installed on the bridge body that has been poured. One end of the traveling section is slidably connected to the load-bearing beam, and the other end of the traveling section passes through the bridge body that has been poured and is anchored to it.

2. The post-tensioned anchor structure for a trackless trolley construction of claim 1, wherein The number of anchoring and traveling components is determined by the number of load-bearing beams deployed.

3. The post-tensioned anchor structure for a trackless trolley construction of claim 2, wherein The anchoring part includes: Four first anchor plates are arranged symmetrically in pairs to form two anchor groups. The two anchor groups are arranged in parallel on the load-bearing beam, and the bottom of the anchor group abuts against the load-bearing beam. Four first anchor cables are arranged symmetrically in pairs to form two anchor cable groups. Two anchor lock groups pass through the two anchor groups respectively. One end of each anchor cable group is anchored to the anchor group, and the other end of each anchor lock group passes through the bridge body that has been poured and is anchored to the bridge body that has been poured.

4. The post-tensioned anchor structure for a trackless trolley construction of claim 3, wherein In each anchoring assembly, the two first anchoring plates are anchored by anchoring bolts. The anchoring part further includes: Multiple anchor sleeves are arranged in parallel pairs between two first anchor plates in each anchor group. The height of the anchor sleeves is higher than the anchoring height of the first anchor plate that abuts against the load-bearing beam.

5. The post-tensioned anchor structure for a trackless trolley construction of claim 4, wherein The walking unit includes: Multiple second anchor plates are arranged in parallel on the bridge body that has been poured. Several I-beam support plates are arranged perpendicularly on the multiple second anchor plates. The third anchor plate, a plurality of the third anchor plates are disposed on a plurality of I-beam support plates, the plurality of the third anchor plates are perpendicularly intersecting the plurality of I-beam support plates, and the second anchor plate is disposed parallel to the third anchor plate; A traveling support plate is provided on the third anchor plate and is located at the bottom and both sides of the load-bearing beam; Four second anchor cables are symmetrically arranged in pairs on both sides of the second anchor plate. One end of each second anchor cable passes through the traveling support plate and is anchored to the traveling support plate by anchor bolts. The other end of each second anchor cable is anchored to the bridge body that has been poured. A plurality of first pulleys are symmetrically arranged on the inner side of the walking support plate, and the first pulleys are respectively located on both sides of the load-bearing beam and are slidingly connected to the load-bearing beam. A second pulley is arranged at the bottom end of the load-bearing beam, and the second pulley is rotationally connected to the walking support plate.

6. The post-tensioned anchor structure for a trackless trolley construction of claim 4, wherein The anchoring sleeve is made of elastic material.
