Abstract
The utility model relates to a staple bolt formula mounting structure of steel-pipe pile support safety cat ladder, staple bolt of every certain interval installation on the steel-pipe pile in the steel-pipe pile support outside, two terraced roof beams of cat ladder are respectively through connecting plate and every staple bolt welded connection. The hoop type assembling connection is adopted between the crawling ladder and the support steel pipe pile, no high-altitude welding operation is adopted in the installation process, and the construction risk can be reduced; the steel pipe pile can be protected from being damaged, when the support is dismantled, the hoop is dismounted from the steel pipe pile, and the steel pipe pile can be repeatedly used.
Description
Technical Field
The utility model relates to a steel-pipe pile support that adopts among the building engineering, concretely relates to mounting structure of safe cat ladder on steel-pipe pile support.
Background
The steel-pipe pile support is the interim bearing structure commonly used in the bridge construction, needs constructor to operate on the support sometimes in the work progress, for example when steel structure bridge installation, needs carry out the welding of girder steel segment section, and constructor will follow ground and climb to the support top and carry out welding operation. In order to ensure the safety of constructors, a safe crawling ladder needs to be arranged on the support. The common ladder mounting method is that after a support is erected, a cage type ladder is integrally hoisted to one side of the support by using hoisting equipment and is welded on the outer wall of a steel pipe pile of the support, and a constructor is required to weld the ladder at high altitude, so that great risk is caused; in addition, when the support is dismantled, the crawling ladder needs to be cut off, so that the pipe wall of the steel pipe pile is seriously damaged, and the reutilization is influenced.
Disclosure of Invention
The utility model aims at providing a staple bolt formula mounting structure of safe cat ladder on steel-pipe pile support to the problem that cat ladder welding formula installation method exists on the steel-pipe pile support, avoid the high altitude welding operation in the cat ladder installation, reduce the construction risk to avoid causing the damage to the steel-pipe pile.
The technical scheme of the utility model as follows:
the utility model provides a staple bolt formula mounting structure of steel-pipe pile support safety cat ladder, the cat ladder is the cage structure, including the ladder beam of two vertical settings, the welding has many cat ladder foot bars between two ladder beams, still welds the arc cage hoop that multichannel level set up on two ladder beams, welds the cage pole setting that protects of many vertical settings between each cage hoop, its characterized in that: and the hoops are arranged on the steel pipe piles outside the steel pipe pile supports at regular intervals, and the two ladder beams of the ladder stand are respectively connected with each hoop in a welding manner through connecting plates.
The utility model changes the welding connection structure between the crawling ladder and the steel pipe pile into the hoop type assembly connection, and the installation process has no high-altitude welding operation, thus reducing the construction risk; the steel pipe pile can be protected from being damaged, when the support is dismantled, the hoop is dismounted from the steel pipe pile, and the steel pipe pile can be repeatedly used.

fig. 2 is a schematic top view of the present invention;
fig. 3 is a front view structure diagram of the present invention.
Detailed Description
As shown in fig. 1, 2 and 3, a safety ladder is attached to the steel pipe pile 1 outside the steel pipe pile support. The ladder stand is of a cage type structure and comprises two vertically arranged ladder beams 2, a plurality of ladder stand foot bars 3 are welded between the two ladder beams 2, a plurality of horizontally arranged arc-shaped cage hoops 4 are further welded on the two ladder beams 2, and a plurality of vertically arranged cage protection vertical rods 5 are welded between the cage hoops 4; the anchor ear 6 is arranged on the steel pipe pile 1 at the outer side of the steel pipe pile support at regular intervals, and the two ladder beams 2 of the ladder are respectively connected with each anchor ear 6 in a welding mode through the connecting plates 7.
Before the support is erected, the hoop can be fastened on the steel pipe pile of the support in advance on the ground, and then the two ladder beams of the cage type ladder stand are welded with each hoop through the connecting plate; when the support is installed, the steel pipe pile provided with the hoop and the crawling ladder is integrally hoisted in place by utilizing hoisting equipment, the safety crawling ladder is installed together with the steel pipe pile, high-altitude welding operation is avoided, and construction risks can be reduced; when the support is dismantled, pull down the staple bolt from the steel-pipe pile, the steel-pipe pile can not receive the damage, consequently can reuse many times.
