Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of guardrail construction auxiliary tool, specifically relates to a trestle edge column positioner. BACKGROUND

[0002] Trestle is very widely used in the engineering construction process, and is a temporary bridge facility built for transporting materials, equipment and personnel. The trestle is usually built by steel or prefabricated concrete components, and has strong bearing capacity and stability. Because steel has good strength, toughness and recyclability, the trestle deck is usually made of steel. In order to protect the safety of personnel and equipment, a series of protective columns are usually set at the edge of the steel trestle.

[0003] In the installation of the traditional trestle edge protective column, the construction personnel first need to determine the installation position of the column by relying on construction experience or through the method of pulling a line, then vertically erect the column on the bridge deck, and then weld the column and the bridge deck. On the one hand, during the process of determining the installation position of the column, even if the distance of the column from the edge of the trestle is determined by the method of pulling a line, errors are likely to occur due to manual reasons, resulting in distortion of the overall line shape of the edge protection and poor appearance of the bridge deck. On the other hand, during the welding period, other workers need to maintain the vertical state of the column, which is easily affected by manual or construction environment, resulting in poor verticality of the column installation, and phenomena such as non-uniform height of the edge protection top surface and height not meeting the requirements, and low efficiency.

[0004] In order to standardize the installation of the trestle edge column, a straight-buried guardrail column welding auxiliary positioning device is disclosed in patent 202223339383.4, which is provided with a horizontal base and a vertical positioning rod in the middle of the horizontal base. When in use, the guardrail column is only needed to be fitted with the positioning rod and fixed, so that the vertical state between the guardrail column and the concrete foundation can be maintained. However, the implementation of the technical scheme of the patent is premised on that the horizontal base is completely fitted with the concrete foundation. If the device is applied in the installation of the trestle edge column, the undulations of different areas of the trestle plane will make the positioning rod not vertical to the ground. During the long-distance installation of the guardrail, due to the lack of reference for the verticality, the verticality of the installed guardrail will have a large deviation. Moreover, if the device is applied in the installation of the trestle edge column, the distance between the column and the edge of the trestle cannot be directly determined, and the construction efficiency is low. UTILITY MODEL CONTENTS

[0005] The utility model is to overcome the defects in the prior art that it is difficult to determine the installation position of the column and whether the column is vertical at the same time through the existing device during the installation of the trestle edge column, the construction efficiency is low, and the construction effect is greatly affected by manual work, and provides a trestle edge column positioner to overcome the above defects.

[0006] To achieve the above object, the utility model discloses the following technical scheme realizes:

The verticality of the main body column can be ensured through the plumb line assembly, and the installed edge column is also vertical through the multiple clamping assemblies.

[0012] As a preferred, the base assembly is provided with a height adjusting assembly. When the body column is found not vertical by the plumb bob assembly, it is inconvenient to adjust the height of the base assembly by means of a gasket or the like, so the height adjusting assembly is arranged on the side of the base assembly in contact with the trestle, facilitating the adjustment of the positioner. In practice, the height adjusting assembly can be arranged only on the side away from the body column, so as to adjust the inclination of the whole device by adjusting the single height adjusting assembly.

[0013] As a further preferred, the height adjusting assembly comprises an adjusting screw bolted to the base assembly, and an adjusting seat fixedly connected to the adjusting screw bolt. In order to facilitate the installation of the device, the height of the base assembly is adjusted by means of the adjusting screw bolt, and the adjusting seat is arranged at the bottom of the adjusting screw bolt, so that the overall structure is more stable after the height is adjusted.

[0014] As a preferred, the clamping assembly comprises two or more extension rods fixed to the base assembly, and the extension rods are provided with hooks at the ends away from the base assembly, for clamping the edges of the trestle.
