Description

Limiting structure at segment of modular structure

Technical Field

Background

In recent years, along with the popularization of design concepts such as assembly type, green and low carbon, modular assembly type design and construction are gradually applied to high-pile wharf engineering. The structural style of the pier is different from that of a traditional high-pile pier, except for a connecting node, all pier main body components adopt prefabricated structures, if a modular prefabricated beam is adopted by a beam, a longitudinal beam system and a superposed panel in a traditional upper structure are integrated into a single block or a plurality of modular components, the expression form is a modular pi-shaped plate and the like, a main body large component block is assembled, and finally, the structural integrity is fully ensured by utilizing a reinforced cast-in-place node.

The wharf structure mainly bears horizontal loads such as mooring force, impact force and the like, and displacement can be generated among the wharf segments due to non-uniformity of load effect among the segments and occurrence frequency difference. The traditional structure adopts the cast-in-place concrete of segmentation department, and the plane form is tooth bank type or unsmooth type. The dislocation of the segments is shown as obvious displacement difference between the segments, concrete damage caused by arching of concave-convex ridge-shaped expansion joints, serious concrete cracks and the like. And a wharf project adopts a double-side short-span simple support design, the displacement difference of adjacent sections is adjusted by the simple support, but after the wharf project is used, the simple support structure is generally damaged, concrete at the end part of a simple support beam cracks, and the like, so that potential safety hazards exist in the use of the wharf structure.

How to adopt a horizontal limiting measure suitable for the modular structure segmentation based on the existing theoretical analysis and use experience is a problem that designers should consider.

Furthermore, the limiting structure at the modular structure segment also comprises a shear bolt which is embedded at the side part of the modular pi-shaped plate in advance and extends out of the modular pi-shaped plate, and an anti-corrosion coating is arranged on the surface of the extending part of the shear bolt. The surface of the shear bolt is provided with an anti-corrosion coating which can play a role in preventing rusting. The shear bolt and the cast-in-place node are poured together, and the shear bolt plays a main role in shearing resistance at the subsection. The diameter and the number of the shear bolts are increased or decreased according to the design grade of a wharf and the conditions such as local seismic fortification requirements, so that the shear bolts can be matched with a rubber cushion layer, and the structural strength of a cast-in-place node is guaranteed while concrete is prevented from being pulled to crack and fall off.

Furthermore, a plastic foam board is placed between the modularized pi-shaped board and the cast-in-place node. The modularized pi-shaped plate and the cast-in-place node are rigid blocks. The plastic foam board is a flexible material. The flexible material can form a buffer zone between the rigid blocks, and the longitudinal displacement is prevented from generating friction damage.
