Abstract

The utility model provides an assembled connection structure of landing stage guardrail pole setting and worker steel bearing beam, the welding has a bed plate at the lower extreme of guardrail pole setting, and 4 screws have been seted up to the symmetry on the bed plate, sets up the screw that corresponds with the screw on the bed plate at the last flange plate tip of worker steel bearing beam, through relative bolted connection for the screw between the bed plate of guardrail pole setting lower extreme and the last flange plate of worker steel bearing beam. The utility model discloses need not weld when landing stage guardrail installation, the installation rate is fast, dismantles all parts repeatedly usable in back, can practice thrift construction material.

Description

Assembly type connecting structure of trestle guardrail vertical rod and I-steel bearing beam

Technical Field

The utility model relates to a landing stage guardrail's that aquatic bridge construction was set up structure, connection structure between pole setting and the worker's steel bearing beam of concretely relates to landing stage steel pipe guardrail.

Background

The trestle that the bridge construction of aquatic was set up can install the guardrail in trestle both sides usually to guarantee constructor safety of passing. The trestle is transversely usually provided with a steel bearing beam, and two ends of the steel bearing beam protrude out of two sides of the trestle for installing a guardrail. The guardrail comprises guardrail vertical rods and cross rods, and the vertical rods are made of small-diameter steel pipes generally. During the usual construction, the lower end of the vertical rod is directly welded with the engineering steel, a large amount of welding operation is needed on the spot, the construction in rainy and snowy weather is impossible, the method is adopted to influence the installation progress of the guardrail under the conditions of large installation work amount and tight construction period of the guardrail, and the guardrail needs to be cut for construction after the construction is finished and can be damaged to influence the reuse.

Disclosure of Invention

The utility model aims to improve present guardrail pole setting welded fastening mode, provide an assembled connection structure of worker's steel and steel pipe guardrail pole setting for the landing stage guardrail construction can accelerate the construction progress, and it is extravagant to reduce the material.

The technical scheme of the utility model as follows:

the utility model provides an assembled connection structure of landing stage guardrail pole setting and worker steel bearing beam which characterized in that: the lower extreme welding of guardrail pole setting has a bed plate, 4 screws have been seted up to the symmetry on the bed plate, seted up at the upper flange plate tip of worker's steel load-bearing beam with the screw that screw on the bed plate corresponds, through bolted connection for the relative screw between the bed plate of guardrail pole setting lower extreme and the upper flange plate of worker's steel load-bearing beam.

The utility model discloses the base of guardrail pole setting is processed in advance at mill to predetermine the screw at worker steel load-bearing beam both ends according to guardrail mounted position, during guardrail construction on the scene through the bolt with guardrail pole setting and worker steel be connected can, not receive weather change's influence, the construction progress is fast, can realize quick installation, guardrail pole setting can continue to use after the engineering can dismantle, the turnover rate is high, practices thrift the cost.

The utility model discloses can be used to the installation of landing stage guardrail, also can be used to adopt the guardrail installation of drilling platform isotructure of worker steel as the spandrel girder.

Detailed Description

As shown in fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, the utility model discloses there is a bed plate 2 in the welding of landing stage guardrail pole setting 1's lower extreme, 4 screws have been seted up to the symmetry on bed plate 2, describe the upper limb marginal plate tip of worker's steel load-bearing beam 3 seted up with the screw that screw on the bed plate corresponds, be connected through bolt 4 for relative screw between bed plate 2 of guardrail pole setting 1 lower extreme and the upper limb marginal plate of worker's steel load-bearing beam 3.

In order to ensure the strength of the guardrail vertical rod, 4 stiffening plates 5 can be welded between the top surface of the base plate 2 and the outer wall of the guardrail vertical rod 1 in an annular and equidistant manner.

The utility model is used for during the construction, weld the bed plate in advance at guardrail pole setting lower extreme to on the bed plate with the design guardrail mounted position on the worker's steel bearing beam flange board on the screw has been processed in advance, during the on-the-spot installation, directly through bolted connection can, the installation does not need the welding, can loosen the bolt after the construction and pull down the guardrail pole setting, the guardrail material can have enough to meet the need the use.

Claims

1. The utility model provides an assembled connection structure of landing stage guardrail pole setting and worker steel bearing beam which characterized in that: the lower extreme welding of guardrail pole setting has a bed plate, 4 screws have been seted up to the symmetry on the bed plate, seted up at the upper flange plate tip of worker's steel load-bearing beam with the screw that screw on the bed plate corresponds, through bolted connection for the relative screw between the bed plate of guardrail pole setting lower extreme and the upper flange plate of worker's steel load-bearing beam.

2. The fabricated connecting structure of the trestle guardrail upright stanchion and the I-steel bearing beam of claim 1, which is characterized in that: the welding of hoop equidistance between base plate top surface and the guardrail pole setting outer wall has 4 stiffening plates.
