Description

Technical Field

[0001] The present invention relates to the technical field of static load testing of steel structures, and more specifically, to a static load testing loading device for a steel structure frame. Background Art

[0002] The steel structure frame is a building structure system that uses steel as the main structural material. The steel structure frame is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts or rivets. It makes full use of the high strength and lightweight characteristics of steel to reduce the deadweight of the building. Through static load tests, it can be tested whether the bearing capacity of the engineering piles meets the design requirements. Through field test methods, the maximum load corresponding to the foundation before it reaches a state of destruction under the estimated (design) load or when deformation that is not suitable for continued bearing occurs can be tested, thereby ensuring the quality and safety of the project.

[0003] Among them, the patent with announcement number CN106092545B discloses a static load test loading device for a steel structure frame, including a force sensor located directly below the test steel structure frame and a loading mechanism installed on the test steel structure frame, the loading mechanism includes a loading beam, a distribution beam, a synchronous hydraulic jack, an active steel tie rod, a limit steel tie rod, a reaction base, a steel pad, and a steel sleeve. The loading beam and the distribution beam are fastened by bolts at the intersection node position, so that the upper part of the loading mechanism forms a whole. The loading beam is fixedly connected to the lower reaction base through four active steel tie rods located at the four corners of the loading beam and four limit steel tie rods located in the middle of the loading beam. A hydraulic jack is arranged at the upper end of each active steel tie rod at the loading beam, and a force sensor is arranged at the lower part of the four corner columns of the steel structure frame;

[0004] When this structure is in use, according to the actual size of the steel structure frame to be tested and the different positions to be loaded, steel sleeves are used to connect active steel tie rods and limit steel tie rods of different lengths to adjust the size of the steel tie rods. At the same time, the position of the distribution beam can be moved to achieve loading at different positions. However, when this structure is in use, it is not easy to simulate the stress conditions of the steel structure after installation, which results in poor results in static load test conditions. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a static load test loading device for a steel structure frame, aiming to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: A static load test loading device for a steel structure frame, comprising a base for support, wherein a static load pressurizing assembly is arranged on the base;

[0008] It can be seen that in the above technical solution, the steel structure is placed in the bracket, and the first driving motor on the top of the bracket drives the press frame to rotate. When the press frame rotates, the function of pressurizing the steel structure can be realized first, and the second driving motor drives the pull plate to rotate, so that the pull plate and the workpiece rub against each other, thereby realizing the diversity of pressurizing test.

[0010] It can be seen that in the above technical solution, when the slide frame is displaced, it drives the various structures on the slide frame to approach the limit frame, thereby realizing the function of applying lateral pressure to the workpiece, while the slide rail and the pulley can guide and limit the displacement stroke of the slide frame, thereby ensuring the stability of the slide frame during displacement;

[0011] Guide plates mounted on the first reinforcing support plate and used for guiding are provided on both sides of the surface of the frame opening, and a first hydraulic rod for driving is provided between the two guide plates, a traction block slidably connected to the guide plate is provided at the output end of the first hydraulic rod, limiting shafts mounted on the first reinforcing support plate are provided on both sides of the bottom of the guide plate, and a V-shaped rod is rotatably connected to each of the limiting shafts, long waist holes are penetrated on both sides of the V-shaped rod, the two V-shaped rods are stacked, and the bottoms of the traction blocks extend into the stacked long waist holes and are slidably connected to the long waist holes, one end of the two V-shaped rods is provided with a driven rod slidably connected to the long waist hole, one end of the driven rod is rotatably connected to a sliding plate extending into the guide plate and slidably connected to the guide plate, a telescopic rod is provided on one side of the sliding plate, and the guide rod is installed on the sliding plate;

[0012] It can be seen that in the above technical solution, the first hydraulic rod is used to start the displacement of the traction block, and the traction block rubs against the long waist hole when it is displaced, so that the V-shaped rod rotates along the axis point of the connection between the V-shaped rod and the limit shaft, and then the torque during the rotation of the V-shaped rod enables the driven rod to drive the sliding plate to slide in the guide plate, and then each extrusion block can gather toward the axis point of the center plate, and then the steel structure is subjected to a transverse pressurization test while the wrapped loading function is realized, and the function of static load pressurization of the steel structure is realized;

[0014] It can be seen that in the above technical solution, the first reinforcing support plate in the limit frame is driven by the second hydraulic rod to rotate along the axis point of the connection between the first reinforcing support plate and the limit frame, so as to realize the function of adjusting the angle of the first reinforcing support plate when the steel structure is laterally pressurized, thereby simulating the static load stress conditions of the steel structure in different directions and realizing diversity during the test.

[0015] Technical effects and advantages of the present invention:

[0016] 1. The present invention drives the press frame to rotate by the first driving motor on the top of the bracket.

[0018] 3. The present invention starts the displacement of the traction block by the first hydraulic rod. When the traction block is displaced, it rubs against the long waist hole, and then the V-shaped rod rotates along the axis point of the connection between the V-shaped rod and the limit shaft. Then, the torsion force during the rotation of the V-shaped rod enables the driven rod to drive the sliding plate to slide in the guide plate, and then each extrusion block can gather toward the axis point of the center plate, and then the steel structure is subjected to a transverse pressure test while the wrapped loading function is realized, and the static load pressurization function of the steel structure is realized;

[0019] 4.

Through the corresponding coordination of various structures, the pressure frame can first realize the function of pressure test on the steel structure when it rotates. The pulling plate rubs against the workpiece to realize the diversity of the pressure test. Through the various structures on the sliding frame approaching the limit frame, the function of lateral pressure on the workpiece is realized. Through the various extrusion blocks gathering towards the axis point of the center disk, the steel structure is then subjected to a lateral pressure test while the function of wrap-around loading is realized, and the function of static load pressure on the steel structure is realized. It is easy to simulate the static load stress conditions of the steel structure under different conditions. BRIEF DESCRIPTION OF THE DRAWINGS
