Description

Technical Field

[0001] The invention relates to the technical field of steel structure stress detection, in particular to a building steel structure stress detection device. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. Steel structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields. Steel structures are prone to rust. Generally, steel structures need to be rust-free, galvanized or painted, and maintained regularly.

[0003] Stress is widely present inside steel structures. During the production and use of steel structures, stress detection is required to detect the surface stress of the workpiece, so as to conduct qualitative and quantitative analysis of stress. In addition to judging its quality, stress detection can also improve the process according to the stress distribution.

[0004] Patent document with publication number CN115266379B discloses a stress detection device for building steel structure, which installs two ends of an I-beam on a first clamping assembly and a second clamping assembly respectively, and limits the position of the I-beam by a clamping block. Then, the operator adjusts the fixed frame to a vertical state or a horizontal state according to the detection requirements. When the fixed frame is adjusted to a vertical state, the vertical load of the I-beam can be simulated by controlling the first hydraulic telescopic rod, and the horizontal load of the I-beam can be simulated by controlling the second hydraulic rod, so as to detect the load state of the I-beam when used as a column; when the fixed frame is adjusted to a horizontal state, the vertical load of the I-beam can be simulated by controlling the second hydraulic telescopic rod, and the horizontal load of the I-beam can be simulated by controlling the first hydraulic rod, so as to detect the load state of the I-beam when used as a beam.

[0005] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems: When in use, the building steel structure stress detection equipment simulates the I-beam into the horizontal and vertical states during use, and simulates its actual use state by applying load, so as to obtain the actual stress conditions. However, in the actual application process, because the steel structure is often erected in an inclined state to support the construction of various main structures, it is difficult to fully simulate the use state of the steel structure and there are certain limitations.

[0020] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows: Embodiment 1: This embodiment introduces a specific structure of a building steel structure stress detection device, specifically referring to Figure 1-Figure 10 As shown, it includes a fixed support member 1 and an adjustable support member 5 arranged on one side of the fixed support member 1, a bottom plate 6 is commonly arranged between the bottoms of the fixed support member 1 and the adjustable support member 5, and a hydraulic push rod 4 is arranged on one side of the fixed support member 1; like Figure 1As shown, the fixed support member 1 includes a fixed column 101, one end of the fixed column 101 is assembled and connected with an angle seat 102, the inner side of the angle seat 102 is assembled and connected with a support seat 103, the inner side of the support seat 103 is rotatably connected with an adapting seat 104, one side of the adapting seat 104 is assembled and connected with a U-shaped seat 105 through a processed cut surface, and one side of the middle part of the fixed column 101 is assembled and connected with an angle plate 3; Among them, by sleeve-fitting the support shaft 107 inside the adapting seat 104 and externally interferingly fitting the bearings 106 at both ends of the support shaft 107, the support shaft 107 can support the adapting seat 104 to rotate inside the support seat 103; like Figure 1 As shown, the adjustment support member 5 includes a support column 502, and a sliding column 501 is slidably connected inside the support column 502 (the power of the movement can be provided by a hydraulic cylinder), and one end of the sliding column 501 is hingedly connected to a U-shaped seat 2 503, and two cushion columns 506 are processed on the front and back of the bottom of the support column 502, and a shaft rod 507 is processed on one end of the cushion column 506; The bottom plate 6 is processed with a movable groove 1 7 and a movable groove 2 8 inside, and the movable groove 1 7 and the movable groove 2 8 are vertically staggered and connected to each other in the middle; Among them, by making one end of the support column 502 movably connected to the inside of the movable strip groove 1 7, and the shaft rods 507 located on the front and back sides of the support column 502 movably connected to the inside of the movable strip groove 2 8, when the outer sides of the four shaft rods 507 are simultaneously interference-fitted with the bearing 2 508, and the same rolling sleeve 509 is sleeved on the outer sides of the two bearings 2 508, the rolling sleeve 509 can be rollingly connected to the bottom inner wall of the movable strip groove 2 8, thereby reducing the resistance of the support column 502 when it moves inside the movable strip groove 1 7; Secondly, by making the two ends of the hydraulic push rod 4 respectively assembled and connected between the angle plate 3 and the U-shaped seat 105, one end of the fixed column 101 is processed to the top of one end of the base plate 6. When one end of the steel structure to be inspected is erected on the top of the fixed support 1, and the other end is erected on the top of the adjustable support 5, the hydraulic push rod 4 can be used to control the rotation of the connection point between the steel structure to be inspected and the fixed support 1, so that one end of the adjustable support 5 moves with the steel structure to be inspected, rises to the top and rotates adaptively.

[0021] Embodiment 2: Based on Embodiment 1, this embodiment introduces the specific structure of the support base 103, such as Figures 1 to 7As shown, three top plates 114 are arranged on the inner side of the support seat 103, three guide slide seats 111 are processed on the outer wall of the support seat 103, the surfaces at both ends of the three top plates 114 are sleeve-connected with guide slide bars 110, the outer side of the guide slide bars 110 is sleeve-connected with spring 2 115, and a connecting plate 109 is processed between one end of two positioning slide sleeves 108 on one side of the same top plate 114; Among them, the three top plates 114 and the three guide slides 111 are arranged at equal intervals around the center of the adaptive seat 104, and the positioning sleeve 108 is slidably connected to the inside of the support seat 103 and the guide slide 111. When the steel member to be detected is at the top of the fixed support member 1 and the adjustment support member 5 and is subjected to pressure from the top to the bottom, the connecting plate 109 presses the spring 2 115 on the surface of the guide slide 111, so that the surface on one side of the connecting plate 109 fits with the surface on one side of the top plate 114, and the surface on one side of the top plate 114 is supported on the arc surface of the adaptive seat 104, which can reduce the stress on the detection bracket when the steel member to be detected is under pressure (in this state, the stress is mainly borne by the multiple springs 2 115, the hydraulic oil inside the hydraulic push rod 4, and the hydraulic cylinder set between the support column 502 and the sliding column 501); At the same time, a pressure sensor 112 is provided on one side of the connecting plate 109 (the transmission line on the pressure sensor 112 passes through the inside of the guide slide 111, and the pressure sensor 112 adopts the well-known technology in the art, and applies matching parts and using methods), and a spring 113 is provided on one end of the pressure sensor 112. By making one end of the pressure sensor 112 supported on the surface of one side of the connecting plate 109, the pressure sensor 112 is driven by the top plate 114 to press the guide slide 111 inside the guide slide 111 at one end, and the pressure sensor 112 itself is slidably connected to the inside of the guide slide 111, and the actual pressure and force direction of the steel member to be detected under the pressure state can be monitored with the help of the pressure sensor 112; Secondly, in order to ensure that the positioning sleeve 108 and the guide slide rod 110 can move inside the angle seat 102 when moving, and will not affect the connection and fixation between the support seat 103 and the angle seat 102, as shown in FIG. Figure 4 and Figure 7 As shown, a movable notch 2 12 is processed inside the corner of the corner seat 102, and a movable notch 1 11 is processed inside both ends of the corner seat 102. By making three guide slides 111 correspond to two movable notches 1 11 and one movable notch 2 12 respectively and accommodated therein, support can be provided for the connection between the support seat 103 and the corner seat 102; Furthermore, in order to allow the support shaft 107 and the bearing 106 to move when the adaptable seat 104 moves inside the support seat 103, Figure 4 and Figure 6As shown, the front and back sides of the support seat 103 are both processed with fan-shaped grooves 10 and 19. By making the two fan-shaped grooves 19 located on the inner sides of the two fan-shaped grooves 10, the two bearings 106 are movably connected inside the two fan-shaped grooves 10, and the two ends of the support shaft 107 are movably connected inside the two fan-shaped grooves 9 respectively. When the adaptation seat 104 moves inside the support seat 103, interference between the support shaft 107, the bearing 106 and the support seat 103 can be avoided.

[0022] Embodiment 3: Based on Embodiment 1 and Embodiment 2, this embodiment introduces the specific structure of the U-shaped seat 2 503, such as Figure 1 , Figure 2 and Figure 8 As shown, both sides of the U-shaped seat 503 are processed with a limited slide groove 2, and the limited slide groove 2 is slidably connected with a roller 504, and a screw 505 is provided on one side of the roller 504; By threading the screw 505 into the inside of the second U-shaped seat 503 and pushing the roller 504 to extend from the inside of the second U-shaped seat 503, the steel member to be inspected placed on the top of the fixed support 1 and the adjustable support 5 can be clamped and fixed; Secondly, by making the rolling directions of the two rollers 504 the same, when the screw 505 is used to push the roller 504 to clamp and fix the steel member, it does not affect the rolling of one side of the roller 504 in the long side direction of the steel member to be detected between the adjusting support 5 and the top of the fixed support 1, ensuring that the hydraulic push rod 4 controls the up and down movement of the U-shaped seat 105, so that the adaptive seat 104 rotates inside the support seat 103, and is not affected by the change in the distance between the U-shaped seat 2 503 and the U-shaped seat 105 when the steel member is converted from a horizontal state to an inclined state.

[0023] Specifically, when using the building steel structure stress detection equipment to detect steel components: First, insert one end of the steel structure into the interior of the U-shaped seat 105, and install the other end of the steel structure into the interior of the U-shaped seat 2 503, keep the steel structure in a horizontal state, adjust the threaded connection between the screw rod 505 and the U-shaped seat 2 503, push the roller 504 to slide inside the U-shaped seat 2 503, and extend it from the interior of the U-shaped seat 2 503 to clamp and fix the steel structure; In this state, the detection pressure is applied from the top to the bottom. The adaptable seat 104 is connected to the U-shaped seat 105 and the steel member, so the top plate 114 directly below the adaptable seat 104 is pressed toward the bottom. The top plate 114 is inside the two positioning sleeves 108 through the two guide slide bars 110, and uses the connecting plate 109 to squeeze the two springs 115, and uses the connecting plate 109 to press the pressure sensor 112, so that the spring 113 is compressed (the pressure sensor 112 can monitor the pressure state of the steel member in this state); At the same time, the support shaft 107 located inside the adapting seat 104 moves inside the fan-shaped groove 1 9, and the bearings 106 at both ends of the support shaft 107 move in the fan-shaped groove 2 10, which can satisfy the state that the adapting seat 104 moves inside the supporting seat 103 and applies pressure to the top plate 114; Then, the hydraulic push rod 4 is started, so that the hydraulic push rod 4 controls the U-shaped seat 105 to drive the adapting seat 104 to rotate inside the supporting seat 103 under the support of the angle plate 3, and the supporting column 502 can control the sliding column 501 to extend from the inside of the supporting column 502 by setting a hydraulic cylinder inside it, so as to support the steel member between the U-shaped seat 2 503 and the U-shaped seat 105 in most of the tilted states (and for the stress detection in the axial direction of the steel member, one end of the steel member is removed from the inside of the U-shaped seat 105 to keep the steel member When the steel member is connected and fixed to the U-shaped seat 2 503, the U-shaped seat 2 503 is rotated around the sliding column 501 and is in a vertical state. When one end of the steel member is in contact with the top of the bottom plate 6, pressure can be applied from the top to the bottom to make the steel member bear force) to simulate the actual use state. During this process, the sliding column 501 rises from the inside of the supporting column 502, and the U-shaped seat 2 503 rotates around the hinge point between the sliding column 501 and the steel member. As the steel member switches from a horizontal state to an inclined state, the roller 504 rolls on the surface of the steel member. In this state, detection pressure is applied from top to bottom, and pressure is applied to the three top plates 114 at the bottom and one side of the adaptation seat 104. The top plates 114 are inside the two positioning sleeves 108 through two guide slides 110, and the two springs 2 115 are squeezed by the connecting plate 109. The pressure sensor 112 is pressurized by the connecting plate 109, so that the spring 1 113 is compressed, so that the three pressure sensors 112 are used to monitor the pressure and force direction.

[0024] It is worth noting that: when the steel structure switches from a horizontal state to an inclined state, the roller 504 rolls on the surface of the steel structure, and can be replaced by a rolling sleeve 509 which is sleeved on the outside of the shaft 507 (a bearing 2 508 is first sleeved on the outside of the shaft 507, against one side of the cushion column 506, and after one end of the rolling sleeve 509 is sleeved on the outside of a bearing 2 508, another bearing 2 508 is sleeved between the rolling sleeve 509 and the shaft 507), and rolls on the bottom inner wall of the movable groove 2 8. Based on the fact that the connection points between the steel structure and the adaptive seat 104 and the U-shaped seat 2 503 remain unchanged, when the steel structure tilts (turns into the hypotenuse of a triangle, pulling the support column 502 closer to the fixed column 101), the support column 502 slides inside the movable groove 1 7, and the rolling sleeve 509 rolls on the bottom inner wall of the movable groove 2 8 to adapt to the change in the tilt state of the steel structure.

[0025] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
