Counter-force plate loading hole construction method and device

Abstract

The invention provides a counter-force plate loading hole construction method and device. According to the construction method, the mode that loading hole assembling units are assembled on the site is used, the loading hole assembling units are lifted to a specified position and then are connected, through measuring and positioning in advance and deformation detection in the construction process, the design of a loading hole mounting system and a counter-force plate form board erecting system is combined, and the construction precision is maximally guaranteed. The loading hole mounting system also ensures that loading hole single bodies are quickly and precisely spliced and assembled, so that high-precision mounting construction of counter-force plate loading holes is achieved successfully, the labor intensity is lowered, and materials, labor, working period and cost are saved. The scale of a counter-force plate can achieve the purposes that the area is about 4000 square meters, the thickness is 800 millimeters, and 8692 loading hole single bodies are included in the counter-force plate. The counter-force plate is combined with a counter-force wall for use, the earthquake damage load test of an eight-floor building can be achieved, however an existing construction process can not achieve the height, and higher economic benefits can be achieved. The counter-force plate loading hole construction method and device are widely applied to construction of counter-force plate loading holes.

Description

technical field [0001] The invention relates to a construction method and device for a counter force plate in civil construction engineering. Background technique [0002] Our country is in a multi-seismic zone, and earthquakes cause great vibrations to buildings, which often cause serious losses of life and property. Therefore, it is necessary to pay attention to promoting the research and application of earthquake engineering in terms of the actual situation in our country. To ensure the seismic performance of some large-scale architectural models of large tonnage or full-scale components, it is necessary to have large-scale, high-rigidity reaction devices and corresponding large-scale multi-functional testing machines as supports.

Problems solved by technology

[0003] In the structural components of the reaction force device, the precision control of the loading hole is crucial to the accuracy of the test data of the test component. As a reinforced concrete component constructed by hand, it consumes a lot of manpower and material resources, the construction process is complicated, and the construction efficiency is low. The construction quality is often difficult to guarantee. At present, the construction technology and process for the precision control of large-area and large-number loading holes are not perfect and mature. The key points and difficulties of the construction of the reaction plate are: 1) The location is special and connected to the surrounding structures , the cross-construction organization is difficult; 2) The precision of the loading hole is high, and it is difficult to control the precision of each stage of processing and installation; 3) The concrete surface survives at one time, and it is difficult to control the accuracy of the flatness of the pouring surface
