Abstract
The utility model discloses an inclined bracing steel enclosing purlin shear pedal reinforcement system comprising fender posts and a steel enclosing purlin. The system is characterized by further comprising shear pedals in a triangular shape. The two shear pedals are arranged at a corresponding position of each inclined bracing behind the steel enclosing purlin and fixed between the fender posts and the steel enclosing purlin. Partial gaps among the steel enclosing purlin, the shear pedals and the fender posts are filled with sprayed concrete. Each shear pedal is a triangular formed by welding of three steel plates. A steel plate A is attached to and fixed to the fender posts, a steel plate B is welded to the steel plate A, the bottom of the steel plate B and the bottom of the steel plate A are welded to one face of a steel plate C, and the other face of the steel plate C is welded to the steel enclosing purlin. The system can transfer stress of a steel enclosing purlin bracing system to the fender posts, and the fender posts can prevent relative sliding of the steel enclosing purlin bracing system to guarantee structural safety and stability.
Description
Technical field
The utility model relates to the realm of building construction; Relating in particular to a kind of bearing diagonal steel encloses the purlin shearing resistance and pedals hardened system.
Background technology
At open-cut station air channel and agent structure intersection, station and wind booth structure built by opencut method place, the steel support system has a denominator, and all take bearing diagonal as main, these support with the hat beam angle of cut all less than 90 degree.The intersection point place can produce tangential and normal direction both direction active force when pre-applied force applied, and balanced each other in tangential direction and hat beam support counter-force; Normal orientation power and Guan Liang and enclose frictional force balance between purlin.Supporting the pre-applied force minimum is 10t, and steel encloses purlin surface smoother, and the frictional force between fender post is less, causes when applying pre-applied force, and steel encloses purlin and can occur moving to normal orientation, can't continue to apply pre-applied force; After taking the fixation pre-applied force to finish, after the later stage space enclosing structure is stressed, encloses purlin and can move to normal orientation, thereby cause space enclosing structure unstability, distortion, serious meeting causes foundation pit collapse.
The utility model content
Technical problem to be solved in the utility model provides a kind of bearing diagonal steel and encloses the purlin shearing resistance and pedal hardened system, can will enclose the stressed fender post that passes to of purlin support system, and fender post can stop the relative sliding that encloses the purlin system to guarantee that structural safety is stable.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A kind of bearing diagonal steel encloses the purlin shearing resistance pedals hardened system, comprise that fender post and steel enclose purlin, is characterized in that: comprise that also shearing resistance pedals, described shearing resistance is pedaled and is triangle, enclose the behind of purlin at steel, the position that the per pass bearing diagonal is corresponding arranges two shearing resistances and pedals and be fixed on fender post and steel encloses between the purlin.
Described steel encloses purlin, shearing resistance is pedaled tamps with sprayed mortar with the fender post gap.
Described shearing resistance is pedaled and is adopted three block plates to be welded into triangle; Steel plate A and fender post are adjacent to fixing, steel plate B and steel plate A welding, steel plate B and the one side welding of steel plate A bottom with steel plate C, the another side of steel plate C with enclose purlin and weld.
The another side of described steel plate C with enclose purlin and adopt four sides weld all around welding.
Described fender post and shearing resistance are pedaled the position that contacts and are provided with and tamp pad.
Described purlin and bottom, the fender post junction template of holding sprayed mortar of enclosing.
The beneficial effects of the utility model:
The utility model encloses the behind of purlin at steel, the per pass steel supports corresponding position and two leg-of-mutton shearing resistances are set pedal and withstand on fender post, the stressed conduction of normal direction that steel can be enclosed purlin causes on the fender post, the fender post bearing capacity is larger, the pressure that can pedal the shearing resistance of enclosing purlin produces corresponding counter-force, thereby makes total reach stable state.After the increase shearing resistance was pedaled, bearing diagonal enclosed the purlin quality and is greatly improved, and overall structure is stressed rear reliable and stable, and is with a wide range of applications.
Description of drawings
Fig. 1 the utility model bearing diagonal steel encloses the purlin shearing resistance pedals hardened system way schematic diagram
Among the figure, the 1-steel encloses purlin, the 2-fender post, and the 3-shearing resistance is pedaled, the 4-sprayed mortar
The specific embodiment
Shown in Figure 1, a kind of bearing diagonal steel encloses the purlin shearing resistance pedals hardened system, comprise that fender post 2 and steel enclose purlin 1, it is characterized in that: comprise that also shearing resistance pedals 3, described shearing resistance is pedaled 3 and is triangle, enclose the behind of purlin 1 at steel, the position that the per pass bearing diagonal is corresponding arranges two shearing resistances and pedals 3 and be fixed on fender post 2 and steel encloses between the purlin 1.The stressed conduction of normal direction that steel can be enclosed purlin 1 causes on the fender post 2, and fender post 2 bearing capacities are larger, can pedal 3 pressure to the shearing resistance that steel encloses purlin 1 and produce corresponding counter-force, thereby make total reach stable state.
Described steel encloses purlin 1, shearing resistance to be pedaled 3 and tamps with sprayed mortar 4 with fender post 2 gaps; Described steel encloses purlin 1 and bottom, the fender post 2 junctions template of holding sprayed mortar 4.It is the plane that 3 steel plates are pedaled in shearing resistance, and fender post 2 surfaces are circular, fully closely connected for guaranteeing the joint, adopts the C20 sprayed mortar to tamp.Before sprayed mortar, steel encloses purlin 1 and paves, holds out against, holds sprayed mortar 4 with bottom, fender post 2 junctions with template.
Described bearing diagonal steel encloses the purlin shearing resistance pedals hardened system, it is characterized in that: described shearing resistance is pedaled 3 employings, three block plates and is welded into triangle; Steel plate A and fender post 2 are adjacent to fixing; Steel plate B and steel plate A welding are played a supporting role; Weld with the one side of steel plate C steel plate B and steel plate A bottom, and the another side of steel plate C and steel enclose purlin 1 and adopt four sides weld all around welding.Described fender post 2 and shearing resistance are pedaled 3 positions that contact and are provided with and tamp pad.
Shearing resistance pedals 3 can adopt three 20mm steel plate welding, and steel plate A is of a size of 200 * 400mm, is adjacent to fender post 2; Steel plate B is of a size of 200 * 250mm, with steel plate A welding, plays a supporting role; Steel plate C is of a size of 300 * 650mm, this steel plate one side and 2 block plate bottom weldings, and another side adopts the four sides weld all around, encloses purlin 1 welding with steel.
