Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings and actual test cases, rather than limiting the protection scope of the present invention.

[0044] Such as figure 1As shown, for the prefabricated anti-instability test loading device for T-shaped beams, the horizontal upper beam 1, the vertical vertical beam 2 and the horizontal lower beam 3 form a loading reaction frame, and the upper beam 1 and the vertical Beam 2 is connected by position-adjustable shear bolts 17, the bottom of vertical beam 2 is welded to first hole gusset plate 18, and first hole gusset plate 18 is connected to lower beam 3 by bolt group 21; said lower The beam 3 is anchored on the ground anchor system 4 through the ground anchor bolt 15; the center of the ground anchor bolt 15 corresponds to the center of the channel 16 of the ground anchor system 4;

[0045] It also includes a pair of anti-instability brackets. The anti-instability brackets incl...

Abstract

The invention discloses an assembly-type anti-instability test loading device for a T-shaped beam. The loading device comprises a loading reaction frame. The loading reaction frame is fixedly connected to a lower cross beam; and the lower cross beam is fixed to a ground anchor system. The loading device also comprises a pair of anti-instability supports. The each anti-instability support comprisesan inclined rod and a vertical rod. The vertical rods of the pair of anti-instability supports are arranged oppositely. The anti-instability supports are in assembly connection with long holes in thelower cross beam. The device also comprises a clamping mechanism. The clamping mechanism is mounted on the vertical rods. The clamping mechanism makes contact with a web of a T-shaped beam test piece. The device also comprises a pressure applying mechanism. The pressure applying mechanism is used for applying test pressure to the T-shaped beam test piece. The provided device can prevent overturning or local instability of the test piece without affecting the test result of the T-shaped beam test piece in the whole process, is high in assembly degree, convenient to install and reusable, can besuitable for different sizes and kinds of T-shaped beam test pieces and is wide in applicability.

Description

technical field [0001] The invention relates to the technical field of bridge engineering model tests, in particular to an assembled anti-instability test loading device for T-shaped beams and an experimental method thereof. Background technique [0002] In bridge engineering, the main girder, as a main force-bearing component, has served for a long time in a complex and changeable natural environment and directly bears the vehicle load transmitted by the pavement layer. Its reliability, durability and safety are the key points of bridge design. And the focus of attention in the operation stage. As a form of main beam, T-beam has the advantages of good economy, convenient manufacture and transportation, and fast construction. It is often used in small and medium-span bridge projects. It is often necessary to randomly check some T-beams in proportion to measure its position in the vehicle during bridge construction. Bearing capacity and deformation performance under load. At...
