Pier column limiting tool

Abstract

This utility model discloses a pier column limiting fixture, belonging to the field of pier column limiting construction technology. It includes a base plate, with two limiting plates fixedly installed on the top of the base plate. The two limiting plates are symmetrically arranged along the central axis of the base plate. Several support plates are fixedly connected between the limiting plates and the base plate, and the support plates are evenly spaced. This utility model solves the problem in the prior art where, when lifting and removing cap beam piers, the small area of ​​the bottom support point of the cap beam and the large weight of the head cap beam with uneven weight distribution make direct lifting and unloading prone to twisting, leading to difficulty in lowering the pier and causing great inconvenience. The new fixture is simple and convenient to operate, and highly practical.

Description

Technical Field

[0001] This utility model relates to the field of pier column limiting construction technology, specifically a pier column limiting tool. Background Technology

[0002] Road and bridge engineering, as a fundamental infrastructure project, is an important component of urban transportation networks. Highway bridges typically use bridge piers for support, specifically through cap beams that transfer the structural loads of the bridge deck and other structures to the bridge piers.

[0003] When lifting and removing the cap beam pier, because the bottom support area of ​​the cap beam pier is small and the head cap beam is heavy and the weight distribution is uneven, directly lifting and unloading the cap beam pier can easily cause it to twist, making it difficult to lower and very inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a pier column limiting fixture to solve the problem in the prior art that when lifting and removing cap beam piers, the cap beam pier is prone to twisting due to the small support area at the bottom of the cap beam pier and the large weight of the cap beam at the top with uneven weight distribution. This makes it difficult and inconvenient to lift and unload the cap beam pier directly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pier column limiting fixture, including a base plate, two limiting plates are fixedly installed on the top of the base plate, the two limiting plates are symmetrically arranged along the central axis of the base plate, and a plurality of support plates are fixedly connected between the limiting plates and the base plate, the plurality of support plates being evenly arranged at equal intervals.

[0006] As a preferred technical solution of this utility model: each of the limiting plates and the base plate is provided with four support plates.

[0007] As a preferred technical solution of this utility model: the limiting plate is welded to the base plate, and the two ends of the support plate are respectively welded to the limiting plate and the base plate.

[0008] The beneficial effects of this utility model by adopting the above technical solution are as follows: This utility model has a simple structure and ingenious design. When hoisting the cap beam pier, the limiting fixture is placed in advance. When the bottom of the cap beam pier is placed in the center of the two limiting plates, the winch lowers the wire rope and the bridge erecting machine moves forward synchronously. Due to the restriction and fixation of the limiting plates on both sides, the cap beam pier can land smoothly. Then the wire rope can be disassembled, which can achieve the smooth unloading of the cap beam pier in a simple and quick manner. Attached Figure Description

[0013] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model. In this utility model, unless otherwise expressly specified and limited, the terms "installed," "connected," "joined," "fixed," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection, an electrical connection, or a connection that can communicate with each other; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two elements or an interaction relationship between two elements. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0014] Please see Figure 1-3 One embodiment of this utility model is a pier column limiting fixture, which includes a base plate 1. Two limiting plates 2 are fixedly installed on the top of the base plate 1. The two limiting plates 2 are symmetrically arranged along the central axis of the base plate 1. A plurality of support plates 3 are fixedly connected between the limiting plates 2 and the base plate 1. The plurality of support plates 3 are evenly arranged at equal intervals.

[0015] Four support plates 3 are provided between each limiting plate 2 and the base plate 1, and the four support plates 3 are evenly spaced. The limiting plate 2 is welded to the base plate 1, and the two ends of the support plate 3 are welded to the limiting plate 2 and the base plate 1 respectively, so that the connection of the limiting plate 2 is more stable.

[0016] Specific implementation method: When hoisting the cap beam pier, the limiting fixture is placed in advance. When the bottom of the cap beam pier is placed in the center of the two limiting plates 2, the winch lowers the wire rope, and the bridge erecting machine moves forward synchronously. Due to the restriction and fixation of the limiting plates 2 on both sides, the cap beam pier can land smoothly. Then the wire rope can be removed. The cap beam pier can be unloaded smoothly in a simple and quick way, which is highly practical.

[0017] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
