Description
Technical field
The present invention relates to a kind of bench frame apparatus, the adjustable self-reaction force bench frame apparatus of especially a kind of kiloton modularized combination type.
Background technology
At present in the scientific research and engineering application process of Structural Engineering, the recurrence of theoretical need dependence full size of the analytical calculation of many labyrinths or vast scale specimen test data is verified and disclosed, and is bigger for this type of larger-size structure test specimen surrender and failing load; And problems such as subterranean tunnel excavation, slope project stability also need to carry out indoor layer during similar model test and study in the Geotechnical Engineering, particularly for the bigger big proportional model test of buried depth, need apply the large-tonnage load.In the process that structure or model are loaded, a reaction frame for loading that is enough to bear its load must be arranged.
Large-scale reaction frame is to load the counter-force bench frame apparatus that counter-force is provided for structural test and geomechanical model test.Especially for loading the big or bigger experiment of load-carrying area of load, top generally adopts many crossbeams that counter-force is provided.Linking between the crossbeam of large-scale reaction frame device and the column is extremely important and crucial, and especially for non-gate-type independent frame structure, the syndeton of middle crossbeam and homonymy front and back column should be easy for installation, strength and stiffness are high.
Reaction frame is of long duration as a kind of early stage facility that applies horizontal loading, and various countries improved it afterwards, is representative with the formula reaction frame of grinding of building of Japan, and it is simple and practical, is particularly suitable for the anti-seismic performance of research framework post, masonry wall etc.The later stage eighties in last century at home colleges and universities such as Harbin Institute of Technology the similar steel reaction frame of building the formula of grinding has appearred.The domestic in recent years reaction frame that many types occur, the well shape reaction frame, the umbrella shape reaction frame that have pile foundation to detect also have HeFei University of Technology to be used for the gate-type reaction frame of structural test.
Chinese patent ZL200720116990.0 discloses a kind of self-equilibrating multifunction structure static test charger, can finish the load test of reinforced beam and post.Its shortcoming can not be adjusted for loading the space, can't carry out large scale structure or model test and load.
Chinese patent ZL200920096460.3 relates to a kind of reaction frame for self-balanced loading.Reaction frame for self-balanced loading is made up of crossbeam, column and octagonal node.Crossbeam and column constitute by H shaped steel, and both interconnect by welding.Octagonal node is made up of a pipe, two block plates and eight ribbed stiffeners.Its shortcoming is to be connected to welding, can't carry out large scale structure or model test and load.
The general reaction frame that Chinese patent ZL200920110127.3 provides can be connected the loading cylinder that needs to install on the web joint in advance owing to have the twin spans girder construction, and web joint and loading cylinder integral lifting are connected on the twin spans beam.The general reaction frame of the twin spans girder construction that utility model has, it is distinct also to have a structure power transmission, with material economic dispatch advantage.Its shortcoming is that reaction frame is not the self-reaction force device, and depth of beam is non-adjustable.
Chinese patent ZL200920037848.6) discloses building structure self-equilibrating static test device, belonged to the testing apparatus of building structural element.Its shortcoming is to load the space can not adjust, and can't carry out large scale structure or model test and load.
Chinese patent 200810138978.9 has been introduced a kind of high-ground stress quasi-3 D visible model testing bench frame apparatus, and the gate-type reaction frame of this device is made up of integral solder base plate, H type cross section column and crossbeam.This device is the self-reaction force device, can carry out the bench model test and load, but base plate is the integral solder base plate that the crossbeam height is non-adjustable, and the loading tonnage is less.
Above-mentioned counter-force bench frame apparatus respectively has characteristics, and comprehensive existing reaction frame for loading mainly contains following shortcoming:
1) many reaction frame for loading need be fixed each afterburning frame, can not realize self-equilibrating;
When 2) loading force is big, need basis preferably, there is certain limitation in the place of testing, can not arbitrarily move, the rigidity of structure and intensity also are difficult to guarantee;
3) function singleness generally is the test at reinforced beam or special ground scale model, can not satisfy the test demand of different structure member, causes the waste of experimentation cost to a certain extent;
4) the loading space is little, and highly fixing, can not adjust up and down, and structure that incompatibility is different or model load;
5) the most of employing with the method for tail trimmer being installed between the heel post, connecting crossbeam at the tail trimmer middle part again of syndeton both domestic and external realizes that processing technology and mounting process require high;
6) counter-force stand tonnage is less, is not suitable for large-tonnage (1000 tons) and loads;
7) the counter-force bench frame apparatus can not assembly unit, incompatible modern testing requirements.
