Horizontal self-balancing counter-force frame capable of applying hundred-ton pressure in complex direction

Abstract

The invention discloses a horizontal self-balancing counter-force frame capable of applying hundred-ton pressure in a complex direction. The horizontal self-balancing counter-force frame comprises a long cross beam, a short cross beam, a bearing table, a supporting column, a mounting frame, a fixing frame and assembling seats, wherein the main body of the long cross beam is a ''cuboid'' structure; the short cross beam is fixedly arranged on the inner side of the long cross beam, and a stabilizing structure is fixedly arranged on the outer side of the short cross beam; the bearing table is fixedly arranged on one side of the short cross beam; the supporting column is fixedly arranged on one side of the bearing table; the mounting frame is fixedly arranged on one side of the supporting column; the fixing frame is fixedly arranged on one side of the mounting frame, and a bearing structure is fixedly arranged on one side of the fixing frame; and the assembling seats are fixedly arranged on the two sides of the long cross beam. By arranging the long cross beam, the short cross beam and the stabilizing structure, the device is novel in overall installation mode, is horizontally placed, can be freely telescopically assembled, meets different test space sizes, and is not limited by indoor floor height and outdoor clearance.

Description

technical field [0001] The invention relates to the technical fields of civil engineering and bridge engineering, in particular to a horizontal self-balancing reaction force frame that can be used to apply hundreds of tons of pressure in complex directions. Background technique [0002] In the field of bridge engineering research, it is often necessary to conduct small-scale scale tests on key components of bridges, such as steel box girder flat roof, steel box girder curved web, concrete box girder flange plate, cable-stayed bridge cable girder anchorage structure, etc., and the test load is often The comprehensive loading method is adopted, that is, the loading force is in addition to the vertical force, horizontal force and oblique force. In order to achieve the purpose of the test, the general reaction force frame device bears the vertical force through a portal type reaction force frame, and then bears the horizontal force through a horizontal reaction force frame, and ...

Problems solved by technology

[0006] The purpose of the present invention is to provide a horizontal self-balancing reaction force frame that can be used to apply hundreds of tons of pressure in complex directions, so as to solve the problem that the existing door-type reaction force frame proposed in the above background technology needs to occupy a large clearance and a high installation space , at the same time, the door-type reaction frame can only provide loading in one direction, and cannot provide multi-directional loading conditions; and the installation structure of the door-type reaction force frame is single, and the shape cannot be changed, and the ordinary door-type reaction force frame cannot be horizontal, vertical, and oblique Large-tonnage loads are applied in multiple directions, and it is impossible for bridge engineering researchers to carry out strength, stiffness and stability tests for key steel structural components in box bridges under complex stress conditions. The problem of applying large tonnage loads, and the cable-beam anchorage structure in the existing cable-stayed bridge cannot be anchored and the problem of applying large tonnage loads
