Nonlinear elastic counterforce centroid algorithm for sealing gasket of prefabricated component

Abstract

The invention discloses a nonlinear elastic counterforce centroid algorithm for a sealing gasket of a prefabricated component. The algorithm comprises the following steps: step 1, obtaining an image of the prefabricated component; step 2, correcting the obtained image; step 3, extracting key information of the image; step 4, correcting the key information of the component in the image; step 5, establishing a coordinate set of key image points of the component; step 6, calculating the centroid of the rubber sealing gasket; and step 7, calculating the counterforce centroid of the rubber sealinggasket. The overall elastic counterforce resultant centroid of the rubber sealing gasket made of a nonlinear characteristic material is calculated under the condition that the waterproof rubber sealing gasket arranged between the components is compressed to different states by a tension load so that the tensioning load of the tensioning jack at the next moment is determined to gradually approach the target position of tensioning of the assembly type component, the preset joint width is achieved and the joint width is ensured to be uniform.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a centroid algorithm of a non-linear elastic reaction force centroid of a prefabricated assembled component gasket installed on a prefabricated assembled component. Background technique [0002] Rubber gaskets are usually used for the waterproofing of prefabricated structure assembly joints. When the components are assembled, the rubber gaskets are squeezed and compressed by the concrete components to form a waterproof seal. According to the requirements of waterproof sealing function, the rubber gasket is distributed continuously and linearly on the contact surface of the component, and its type can be linear, curved or complex linear composed of straight lines and curves. When the component size is large, sometimes two (double seal) or more rubber gaskets are arranged to strengthen the waterproof performance. [0003] Such as Figure 1A and Figure 1B As an e...

Problems solved by technology

However, due to the irregular shape of the components and rubber gaskets during the assembly and tension construction of prefabricated components, it is impossible to accurately determine the tension of each tension point by using the current method of gradually approaching and continuously adjusting based on experience and observation. Tensile load, so it is difficult to ensure that all joint widths of assembled components are consistent, which affects the accuracy and quality of component assembly

At the same time, the inconsistency of the loads at each tension point will cause unexpected additional stress on the member
