Tooling and layout method of mechanical wave detection equipment for concrete filled steel tube columns

Abstract

The invention discloses a concrete filled steel tubular column mechanical wave testing equipment tool. The concrete filled steel tubular column mechanical wave testing equipment tool comprises a body, wherein the body comprises a head end and a tail end in the length direction, and a male connection part and a female connection part which are matched with each other are arranged at the head end and tail end respectively; when the body surrounds a concrete filled steel tubular column by a circle to enable the male connecting part to be attached to the female connecting part, the head end and the tail end are fixedly connected in a sealed mode; sealing parts are arranged at the two ends, in the width direction, of the body respectively; a plurality of clamping ports are formed in the outer surface of the body and evenly distributed in the outer surface of the body, a water injection port is formed in the body and penetrates through the body, the position where the water injection port is connected with the body is sealed, and a detachable sealing plug is arranged at the end of one side of the outer surface of the water injection port. By the adoption of the concrete filled steel tubular column mechanical wave testing equipment tool, preliminary installation efficiency can be improved. The invention further provides an arrangement method for the concrete filled steel tubular column mechanical wave testing equipment tool.

Description

technical field [0001] The invention relates to the field of detection equipment for concrete-filled steel tube columns, and more specifically, relates to a tooling and an arrangement method for mechanical wave detection equipment for concrete-filled steel tube concrete columns. Background technique [0002] In housing construction, a large number of steel pipe concrete columns are used as the support of the house. The strength of the steel pipe concrete columns also affects the stability of the entire house structure. Therefore, in the construction field, it is necessary to detect relevant data for each steel pipe concrete column. [0003] The "Summary of Common Defects and Detection Methods in Concrete-filled Steel Tubes" published by Lu Xuewei, Xu Rong and Wang Guiling of Tongji University discloses the commonly used methods for the quality inspection of steel-filled steel pipe concrete: including non-destructive testing and destructive testing. Here we focus on non-destr...

Problems solved by technology

[0006] 1. Apply putty powder on the surface of the steel tube concrete column, fix the geophone on the putty powder, and then apply the coupling agent. It takes a long time for the putty powder to solidify on the surface of the soil column, and the steel tube concrete column in the current building The number is hundreds of roots, it takes a lot of time to prepare, and the work efficiency is low

[0007] 2. Now, in many cases, the test reports for concrete-filled steel tube columns are generated as plan views. The reason for generating plan views is that there are relatively few test points. Correspondingly, a small number of points are placed on each surface of each steel tube concrete column However, the plan view cannot fully determine the overall situation of a steel pipe column or a column node. Now, with the advancement of technology, the generated report is required to be a three-dimensional map, so more points need to be taken on the surface of the steel pipe concrete column To install the geophone, this further highlights the problem in defect 1, that is, it takes a lot of time to prepare for the initial work, and the existing technology cannot meet the current actual engineering requirements
