Problems solved by technology

After pasting with the traditional pasting method, the strain gauges are easily damaged during the tamping process, and due to the great damage caused by manual tamping, the corresponding damage degree of the strain gauges is also relatively large
As a result, the accuracy of strain gauges for measuring the strain of civil structures is low, resulting in low reference value of the measured strain parameters

Embodiment Construction

[0032] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0033] A rammed earth-wood beam-column specimen, such as Figure 1-3 As shown, it includes wooden beam column 1 and rammed earth part 2. The wooden beam column 1 includes a free section 11 and a rammed earth section 12 . The soil body is rammed on the rammed earth section 12 to form the rammed earth part 2 . In common rammed earth-wooden beam-column specimens, the wooden beam-column 1 is cylindrical, and the rammed-earth part 2 is square column-shaped. The wooden beam column 1 can be provided with a plurality of rammed earth sections 12 arranged at intervals. Preferably, the end of the wooden beam column 1 is a rammed earth segment 12 . The rammed earth sections 12 of the plurality of sections correspond to rammed earth bodies respectively. In order to measure the strain parameters of the rammed structure,...

Abstract

The invention discloses a method for installing a derived type built-in strain gauge for a building test piece. The method herein fixes a strain gauge inside a wooden beam column through steps of grooving, grinding, sterilizing, adhering, glue filling, wire traction and the like. The method also forms a protection layer on the surface of the strain gauge, can effectively protect the strain gauge which is rammed into the soil body from being damaged and prevents the strain gauge from being short circuit due to damp, so that the rammed soil-wooden beam column test piece which completes ramming can smoothly undergo the measurement of structural strain, and accurate measurement data can be obtained. Further, the method, by transmitting data through a wire, can conduct effective strain analysis on the rammed soil-wooden beam column test piece based on the measurement data.

Description

technical field [0001] The invention belongs to the technical field of civil engineering structure tests, and in particular relates to a method for installing a built-in strain gauge for a building test piece. Background technique [0002] Strain has always been an indispensable analytical parameter in structural testing in the field of civil engineering. Fujian Tulou is a load-bearing structure with raw earth board walls and wooden beams and columns. It is of great practical significance to study the mechanical properties between earth building rammed earth and wooden beams and columns. [0003] The current measurement of beam strain is usually by means of strain gauges. When measuring, it is necessary to embed and paste the strain gauges in the wooden beam column, and the pasting of the strain gauges needs to be completed before the soil is rammed. After being pasted by the traditional pasting method, the strain gauges are easily damaged during the tamping process, and d...
