Problems solved by technology

[0004] However, the drawing device and the drawing method in the invention patent have two biggest problems of single function and low detection efficiency.
That is: the bending test of the connector cannot be done, and only one connector can be pulled and tested at a time

Embodiment Construction

[0037] The following descriptions are only preferred embodiments of the present invention, and do not limit the scope of the present invention.

[0038] as attached Figure 1-7 As shown in the figure, the test method for the drawing and bending performance of the steel-concrete composite beam connection key includes the following steps in sequence:

[0039] S1, install two groups of connecting keys a on both sides of the vertical plate 202 on the bottom plate 201;

[0040] S2, pour the bridge deck 1 below the bottom plate 201, and pour and fix the connection key a in the bridge deck 1;

[0041] S3. A vertical stiffening plate 301 is arranged between one side surface of the vertical plate 202 and the upper surface of the bottom plate 201, a loading beam 401 is arranged on the vertical stiffening plate 301, and the loading beam 401 is far from the One end of the vertical stiffening plate 203 is provided with a jack 501 for pressing down;

[0042] S4. When the vertical stiffen...

Abstract

The invention belongs to the technical field of bridge engineering, and particularly relates to a steel-concrete composite beam connecting key drawing and bending performance test method and test equipment thereof. The method mainly comprises the following steps: mounting and pouring the connecting key, selectively mounting the vertical stiffening plate, and finally pressing the loading cross beam by the jack, so as to achieve the purpose of simultaneously detecting the drawing and bending performances of the connecting key. The equipment structurally comprises a bridge deck slab, a mounting frame unit, a stiffening plate unit, a connecting frame unit, a loading frame unit and a pressing jack unit, and it is guaranteed that drawing and bending tests of connecting keys are stable and efficient.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a method for testing the drawing and bending performance of a steel-concrete composite beam connecting key, and a testing device thereof. Background technique [0002] Connection keys in the field of road and bridge construction, including studs, steel bars, steel rods, and angle steel, etc., can be used in a variety of different road and bridge construction schemes, such as steel-concrete composite beams, steel-concrete support columns, and steel-concrete bridge decks. [0003] For the connection key, a common test method to test its performance is the pull-out and bending test. However, the existing connection key drawing and bending test methods, such as the Chinese invention patent with the patent publication number CN113670721A and the publication date of 2021.11.19. It discloses a novel drawing monitoring device and a construction method thereof. The...
