Description

Pin-connected panel staple bolt platform of bent cap construction usefulness

Technical Field

The utility model relates to a support of construction usefulness especially relates to a pin-connected panel staple bolt platform of bent cap construction usefulness.

Background

The capping beam is a beam fixed to the top of the pier and used for supporting the upper structure of the bridge. In the construction process of highway bridges, the bridges are usually constructed in the design form of pier columns and cover beams.

At present, before a bent cap of a bridge is constructed, a bracket needs to be built around a pier stud so as to facilitate workers to cast the bent cap in situ, but if a construction object is a higher pier stud, the problems of long bracket building time, low efficiency and high safety risk exist; if the construction foundation is on the river or soft foundation geological conditions, the construction difficulty is increased, and the construction period is prolonged.

In order to reduce the construction cost, save the construction period and improve the working efficiency, people try to adopt the mode of hoop bracket to replace the construction scaffold, and then solve this problem. Chinese patent publication No. CN 208183546U discloses a "hoop bracket for capping construction" (as shown in fig. 1), which is composed of a hoop clasped to a pier column and a steel bracket erected by the hoop. But the product has the defects that the size of the erected bracket is too small and is only close to the plane size of the bent cap, so that the bracket cannot contain the construction operation range of the bent cap, only can be positioned right below the bent cap, and is limited by the guardrail, so that the steel bar binding of the bent cap and the installation of the vertical face template are inconvenient, and the real function of a platform is not achieved. The reason for this is that the use of the bracket as a construction platform is affected due to the unreasonable structural design of the bracket.
