Abstract
The utility model relates to an apparatus for testing the bearing capacity of a steel bar inclined pulling point of a section steel hanging scaffold. The apparatus comprises a section steel triangular support fixed in the bottom of a test press machine; an angle steel inclined strut having two ends fixedly connected on the section steel triangular support; a hanging section steel beam and a steel bar inclined pulling rod which are fixedly mounted on the triangular support; and a piece of loading vertical section steel fixedly mounted on the hanging section steel beam. A welding mode is adopted for fixed installation. With the adoption of the structure, the apparatus for testing a section steel hanging scaffold system of a steel bar inclined pulling type makes up the defect of the system that complex construction points cannot be calculated by calculation based on theories; the weak points and real bearing capacity of the system can be determined truthfully; the system can be guaranteed to be safely and reasonably applied to engineering practices; and favorable economic benefits can be obtained.
Description
Technical field
The utility model relates to a kind of construction equipment, especially a kind of device that tiltedly draws the ultimate bearing capacity of joints test for shaped steel builder's jack reinforcing bar.
Background technology
For the shaped steel builder's jack system of reinforcing bar cable-stayed type, adopt theoretical simplification to calculate usually and try to achieve its ultimate bearing capacity.The shaped steel builder's jack system of reinforcing bar cable-stayed type is in actual application, tiltedly draw the joint structure complexity, different engineering reinforcing bars tiltedly draw the angle difference, the stressing conditions difference, joint structure is also had any different, theoretical calculating needs to simplify computation model, is difficult to conform to actual conditions, can't determine its weak part and bearing capacity situation.
The utility model content
To be solved in the utility model is that the shaped steel builder's jack system of reinforcing bar cable-stayed type is in actual application, can't calculate the problem of determining weak part and ultimate bearing capacity by utility theory, a kind of stressing conditions that tiltedly draws node in can construction simulation is provided, tries to achieve the experimental provision that tiltedly draws node stress deformation situation and bearing capacity situation.
For solving the problems of the technologies described above, shaped steel builder's jack reinforcing bar of the present utility model tiltedly draws the ultimate bearing capacity of joints experimental provision, comprise the shaped steel A-frame that is fixed on the experimental pressure motor spindle, two ends are fixedly connected on the angle steel diagonal brace on the shaped steel A-frame, be fixedly mounted on encorbelment section steel beam and reinforcing bar brace on the A-frame, and be fixedly mounted on the vertical shaped steel of loading on the section steel beam of encorbelmenting.
Described fixed installation is welding manner.
After adopting such structure, the experimental facilities of the shaped steel builder's jack system of this reinforcing bar cable-stayed type, remedy this system and calculated the deficiency that is difficult to the calculation of complex structure node according to theory, can determine its this system's thin spot and true bearing capacity really, guarantee that this system can safe and rationally be applied to engineering practice, obtains good economic benefit.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the front view that shaped steel builder's jack reinforcing bar of the present utility model tiltedly draws the ultimate bearing capacity of joints experimental provision.
