Description
Technical field
The utility model relates to a kind of railway T-beam test unit, especially railway T-beam static test truss.
Background technology
Static test refers to by directly loading beam body and measuring its strain and degree of disturbing, thus determines the test method of the change that beam body occurs under external force and beam body overall work state.Usual utilization is tested from gravity type static load measurement mechanism, and in process of the test, each load(ing) point will be installed respectively, wastes time and energy, and its structure is comparatively complicated, and rolled steel dosage is more, causes processing difficulties, uses inconvenience.
Utility model content
For solving above technical matters, the utility model provides a kind of structure simple, railway T-beam static test truss easy for installation.
Its technical scheme is as follows:
A kind of railway T-beam static test truss, by two structures, the identical and symmetrically arranged steelframe in front and back is formed by connecting, described steelframe comprises top boom and lower boom, column is distributed with between this top boom and lower boom, described column symmetria bilateralis is provided with strut, this strut is obliquely installed, and upper and lower two ends are fixed with top boom and lower boom respectively;
Be distributed with entablature between the top boom of two described steelframes, between the lower boom of two described steelframes, be distributed with sill, between two adjacent entablatures and two adjacent sills, be equipped with brace;
Be provided with oblique strut between two described steelframes, the top boom of this oblique strut upper end and wherein a steelframe is fixed, and the lower boom of lower end and another steelframe is fixed.
Adopt above structure, truss is linked into an integrated entity by two steelframes, multiple leg-of-mutton support system is jointly formed by strut, brace and oblique strut and upper and lower chord member, enhance load-bearing capacity, during test, directly hydraulic jack is placed on load(ing) point, without the need to installing further with truss, easy to use.
Further, described top boom is divided into top boom leading portion and top boom back segment along its length, adopts and be flexibly connected between this top boom leading portion with top boom back segment.When this structure can guarantee test, when beam body deformability is larger, top boom leading portion and top boom back segment can relative movements, with this deflection of decaying.
Further, described lower boom two ends are provided with base for supporting, are connected and fixed for during static test and bottom pedestal.
Further, for convenience of erection hydraulic jack during test, described lower boom bottom part is furnished with cushion block.
Further, described column lower end both sides are respectively equipped with leg-of-mutton wing plate, to guarantee that upright supports is firm.
Beneficial effect:
The railway T-beam static test truss of above technical scheme, adopt integrated design, rolled steel dosage is few, and structure is simple, easy for installation, improves the load-bearing capacity of test unit.
