Description
Technical field
The utility model relates to road and bridge construction field, specifically refers to a kind of Hanging Basket rhombus frame pre-pressing system.
Background technology
Because the elastic deformation of Hanging Basket, nonelastic deformation and rod member connect the reason such as gap, tightness, under the effect of load, Hanging Basket easily produces moderate finite deformation, and absolute altitude changes, and does not meet design requirement.Therefore needed to carry out precompressed test to Hanging Basket before building case beam concrete, determine whether Hanging Basket meets load requirement and deformation rule, determine elastic deformation amount and nonelastic deformation amount, for alignment control provides actual foundation.
Utility model content
The purpose of this utility model is to provide a kind of Hanging Basket rhombus frame pre-pressing system, this system can detect the supporting capacity of Hanging Basket in equivalent load situation, resistance to overturning, elastic deformation and plastic strain, can verify important technological parameters and the functional performance of Hanging Basket in test simultaneously.
The utility model is achieved through the following technical solutions:
A kind of Hanging Basket rhombus frame pre-pressing system, form primarily of rhombus frame, fixation steel plate and root node case, described rhombus frame is two panels and all lies on platform, front suspension centre one end of rhombus frame is fixed on front end node case, the front suspension centre other end stretch-draw of rhombus frame, rhombus frame root end is welded on fixation steel plate, and the rhombus frame root other end is fixed on root node case.Described root node case is upper and lower two, is fixed by fining twisted steel and bolt.Steel strand are connected with in the middle of two described front end node casees.Superposed front end node case and steel strand top are fixed with jack.The front end node case and the steel strand that are positioned at bottom are fixed by ground tackle.
Operating principle: carry out hanging the assembled of indigo plant on the 0# block of having constructed, after the blue system assembles of whole extension completes, carries out precompressed with the sandbag being equivalent to working load to extension indigo plant.Precompressed weight is 120% of the heaviest beam section.Precompressed adopts the mode of classification precompressed, is divided into 4 grades, and first time loads 30% of gross weight, and second time loads 70%, and third time loads 100%, finally loads 120%.The absolute altitude situation of change of observation point is all recorded after each loading.
Exert pressure by 30%, 70%, 100%, 120% level Four load during the precompressed of prismatic frame, simulation box beam waters the main truss displacement deformation that fluence measures Hanging Basket stage by stage.Every grade of loading completes and voltage stabilizing half an hour, and afterbody is 1 hour, and the situation of each rod member of rear inspection has free from flaw, record the relation of power and displacement simultaneously, and according to testing the result measured, drawing the relation curve of power and displacement, obtaining Hanging Basket elasticity and nonelastic deformation.For ensureing the reliability of cradle structure, removing nonelastic deformation, measuring elastic deformation amount, guaranteeing safety and the quality of box girder construction.Unload overload step, by the reverse off-load step by step of loading procedure.Meanwhile, reverse cyclic loadings, unloading three circulations, until nonelastic deformation has all been eliminated, result of the test should arrange out loading test report, and the measurement result of elastic deformation value and nonelastic deformation value is used to guide construction.Load shedding, and measure distortion, record data.
Compared with prior art, the beneficial effect had is the utility model:
(1) system can be checked the bearing capacity of Hanging Basket in equivalent load situation and resistance to overturning and measure the elastic deformation of Hanging Basket when equivalent load and plastic strain;
(2) important technological parameters and the functional performance of Hanging Basket can be verified by system precompressed test.

Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment 1:
As shown in Figure 1, a kind of Hanging Basket rhombus frame pre-pressing system, form primarily of rhombus frame 1, fixation steel plate 2 and root node case 3, described rhombus frame is two panels and all lies on platform, front suspension centre one end of rhombus frame 1 is fixed on front end node case 4, the front suspension centre other end stretch-draw of rhombus frame 1, rhombus frame 1 root end is welded on fixation steel plate 2, and the rhombus frame 1 root other end is fixed on root node case 3.Described root node case 3 is upper and lower two, is fixed by fining twisted steel 8 and bolt 9.Steel strand 6 are connected with in the middle of described two front end node casees 4.Superposed front end node case 4 is fixed with jack 5 with steel strand 6 top.The front end node case 4 being positioned at bottom is fixed by ground tackle with steel strand 6.
Operating principle: it is blue assembled to carry out extension on the 0# block of having constructed, and after the blue system assembles of whole extension completes, carries out precompressed with the sandbag being equivalent to working load to extension indigo plant.Precompressed weight is 120% of the heaviest beam section.Precompressed adopts the mode of classification precompressed, is divided into 4 grades, and first time loads 30% of gross weight, and second time loads 70%, and third time loads 100%, finally loads 120%.The absolute altitude situation of change of observation point is all recorded after each loading.
