Embodiment Construction

[0015] The present invention will be further described below in conjunction with drawings and embodiments.

[0016] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, in the present invention, the long steel column 1 is vertically fixed on the bearing platform 3, and the measured structure model 8 and the short steel column are respectively fixed on the platform 4 on the bearing platform 3 on both sides of the long steel column 1 2. The long steel column 1 and the short steel column 2 are connected by a steel plate 7, and a hole corresponding to the height of the measured structure model 8 is opened on the long steel column 1, so that the long steel column 1 can be adjusted to the same height as the measured structure model 8 A steel shaft 10 is housed in the bearing 9 holes on both sides of the long steel column 1 opening position, and a sprocket 11 is arranged in the steel shaft 10. An encoder 19 is installed on one end of the steel shaft 10 and rotates togethe...

Abstract

The present invention discloses a load-applying and test synthetic experiment device. The long steel column, the measured structure model and the short steel column are vertically fixed on the bearing table, the long steel column is arranged with a hole with height corresponding with the measured structural model, the bearing hole at two sides of the hole is installed with a steel axis with sprocket wheel arranged wherein, one end of the steel axis is installed with an encoder connected with the data collecting case, the steel plate is fixed with an upright lifting cylinder and the upper end of the short steel column is arranged with a horizontal extension cylinder, the servo valve is connected with two cylinders and is electrically connected to the controller and the air pump, one end of the chain is connected with the measured structure model through the sprocket wheel and the other end is connected with the weight seat which is arranged with weights, the weight seat is arranged on the right upper side of the vertical lifting cylinder piston and the side surface is arranged at the front side surface of the horizontal extension cylinder piston. The device can be used for the side horizontal static load and the lateral impact dynamic load of the structure and executing the corresponding displacement test.

Description

technical field [0001] The invention relates to a loading and measuring device, in particular to a loading and testing comprehensive experimental device. Background technique [0002] Civil engineering is a highly practical subject. At present, many domestic colleges and universities aim to cultivate students' innovative thinking and hands-on ability, cultivate teamwork spirit, enhance students' engineering structure design and practical ability, and enrich the campus scientific research and academic atmosphere. Model designs of various structures were carried out. The content of the competition is generally given a certain material, and the contestants are required to design and produce a structure within a certain period of time. After passing the load-bearing capacity test, the one with the largest load-to-load ratio will win, and then comprehensively consider various factors to determine the award level. In terms of materials, white cardboard is generally used in the so...
