DETAILED DESCRIPTION

[0026] Hereinafter, embodiments of a steel beam bearing capacity strength testing device of the present invention will be described with reference to the accompanying drawings.

[0027] The embodiments described herein are specific embodiments of the present invention, which are used to illustrate the concept of the present invention, are illustrative and exemplary, and should not be construed as limiting the embodiments of the present invention and the scope of the present invention. In addition to the embodiments described herein, those skilled in the art can also adopt other obvious technical solutions based on the claims and the contents disclosed in the specification of this application, including technical solutions that adopt any obvious replacement and modification of the embodiments described herein.

[0028] The drawings of this specification are schematic diagrams, which assist in explaining the concept of the present invention and schematically show the shapes of various parts and their mutual relationships. Please note that in order to clearly show the structures of various components of the embodiments of the present invention, the drawings are not drawn according to the same scale. The same reference numerals are used to represent the same parts.

[0029] The following combination Figure 1-7 A steel beam bearing capacity strength testing device according to an embodiment of the present invention is described, which includes:

[0030] The base 10 is used to support other components connected thereto; the structure of the base can be roughly a rectangular parallelepiped structure, for example Figure 2 The form shown in the figure, of course, the base can also be designed as other suitable structural forms according to needs. The material of the base is preferably welded by stainless steel pipes, stainless steel columns, stainless steel plates, etc., so that it has good corrosion resistance.

[0031] The positioning seat plate 20 is fixed to the upper part of the base 10; the positioning seat plate 20 is roughly a rectangular structure, and at least one horizontal slide groove 22 is provided on the upper part of the positioning seat plate 20, and a positioning hole 21 penetrating to the horizontal slide groove 22 is provided on the side of the positioning seat plate 20, and a positioning rod 23 is installed in the positioning hole 21; Figure 2 In the embodiment shown in , the positioning seat plate is a rectangular structure, including a long side and a short side, and a limit block expansion slot parallel to the long side is provided in the middle of the positioning seat plate. The limit block expansion slot is a through structure that penetrates the upper surface and the lower surface of the positioning seat plate, so that the limit block can be moved from the lower surface of the positioning seat plate to the upper surface of the positioning seat plate. A horizontal slide is provided on both sides of the limit block expansion slot, and the horizontal slide can be a through structure that penetrates the upper surface and the lower surface of the positioning seat plate, or a non-through structure, as long as the depth of the horizontal slide is suitable for accommodating the bearing plate slider at the bottom of the bearing plate. The horizontal slide is preferably a T-shaped structure, and the corresponding bearing plate slider is also a T-shaped structure, which can prevent the bearing plate slider from detaching from the slide. The positioning hole is provided on the side of the positioning seat plate, which can facilitate the operation of the positioning rod. The positioning rod can be a screw with an external thread structure, and the positioning hole is provided with an internal thread. The end of the positioning rod can be a disc structure (provided with a straight groove), and the liquid can be set to a hexagonal structure that is convenient for rotation using a wrench.

[0032] The upper part of the load-bearing plate 30 is used to bear the steel beam to be tested, and the bottom of the load-bearing plate 30 is provided with a load-bearing plate slider corresponding to the horizontal slide groove 22 of the positioning seat plate 20, and the load-bearing plate slider can move in the horizontal slide groove 22 and be locked in position by the positioning rod 23;

[0033] A positioning frame 40, the positioning frame 40 is connected to the bearing plate 30, and the positioning frame 40 is used to limit the horizontal position of the steel beam to be measured; a pressurizing device 50, and the pressurizing device 50 is used to pressurize the steel beam to be measured.

[0034] The steel beam bearing capacity strength testing equipment of the above-mentioned embodiment of the present invention can loosen the positioning rod as needed when conducting the steel beam bearing capacity strength test, so that the bearing plate can be moved to different positions along the horizontal slide groove on the positioning seat plate (and thus the steel beam fixed on the bearing plate can be moved to different testing positions for testing). In the bearing capacity strength test of different parts of the same steel beam, there is no need for the testing equipment to remove the steel beam to move the position of the steel beam, which can greatly improve the testing efficiency.

[0035] In a specific embodiment of a steel beam bearing capacity strength test device, Figure 3 As shown, the supporting plate 30 is a roughly rectangular structure, and a guide slot 31 is provided on the side of the supporting plate 30; the positioning frame 40 is provided with a guide slider 41 adapted to the guide slot 31, and the number of the positioning frames 40 is at least two groups, and each group includes two positioning frames 40 arranged in opposite positions. Figure 3The bearing plate shown in the figure is a rectangular structure, including a longer side and a shorter side, and the guide slot is arranged on the longer side. The guide slot can be arranged continuously along the side or in a Figure 3 The form is only set at the position where the positioning frame needs to be moved to. Figure 3 Two spaced guide slots are provided on each longer side. Figure 3 The load-bearing plate of the embodiment shown is provided with four guide slots in total, and four positioning frames can be installed. The cross-sectional structure of the guide slot is preferably T-shaped, and the corresponding guide slider is also T-shaped, which can prevent the guide slider from detaching from the guide slot. The steel beam bearing capacity strength test equipment of the above embodiment of the present invention can achieve clamping and fixing of different positions of the steel beam by adjusting the position of the positioning frame, and is particularly suitable for clamping and fixing special-shaped steel beams, avoiding the problem that the fixed positioning frame cannot clamp the special-shaped position of the special-shaped steel beam, and can move the positioning frame to a position suitable for clamping the special-shaped steel beam by adjusting the position of the positioning frame.

[0036] In a specific embodiment of a steel beam bearing capacity strength test device, Figure 6 As shown, the positioning frame 40 also includes a fixed rod 42, a first extension rod 43, a second extension rod 44, a mounting block 45, a connecting rod 46, a fixed plate 47, a first locking bolt 48 and a second locking bolt 49. A guide slider 41 is installed at the bottom of one side of the fixed rod 42. The upper part of the fixed rod 42 is connected to the telescopic rod, and the top of the telescopic rod is connected to the mounting block 45. One side of the mounting block 45 is hinged to the upper end of the connecting rod 46, and the lower end of the connecting rod 46 is hinged to the fixed plate 47. The bottom of the fixed plate 47 is connected to a fixed plate guide. The upper part of the bearing plate 30 is provided with a T-shaped slide 32 adapted to the fixed plate guide. The function of the positioning frame is to fix the steel beam placed on the bearing plate, that is, to limit the displacement of the steel beam in the horizontal direction. Since the bearing strength test of the steel beam is mainly the bottom and upper part of the steel beam as the force points (the test pressure is in the vertical direction), it is only necessary to limit the horizontal position movement of the steel beam, and the requirements for the degree of fixation can be reduced. However, due to the existence of steel beams of different sizes or special shapes, the positioning frame needs to have a quick adjustment function so as to be suitable for different steel beams to be tested. Since there is an adjustable structure between the fixed rod and the telescopic rod, the height of the mounting block can be adjusted through the above structure. At the same time, since the fixed plate guide is installed in the T-shaped slide groove, when adjusting the height of the mounting block, it is necessary to move the position of the fixed plate guide in the T-shaped slide groove at the same time. Specifically, when the height of the mounting block becomes higher, it is necessary to move the fixed plate guide further away from the fixed rod accordingly; when the length of the telescopic rod is locked, the position of the fixed plate guide is locked accordingly, that is, the position of the fixed plate is locked, and it can be used to fix and limit the horizontal position of the steel beam.

[0037] When adjusting the position of the positioning frame by adjusting the position of the guide slider 41 in the guide slot 31, it is necessary to move the fixed plate guide out of the T-slot 32 at the current position and install it in the T-slot corresponding to the position of the positioning frame after adjustment (the position of the fixed plate guide). Since the above-mentioned positioning frame parts are connected as a whole, the above-mentioned disassembly process can be achieved by disassembling the hinge between the connecting rod 46 and the mounting block 45 or the joint between the connecting rod 46 and the fixed plate 47, but the disassembly and installation process is relatively cumbersome, resulting in a reduction in test efficiency. In a preferred embodiment, combined with Figure 4 As shown, the T-shaped slide groove 32 includes a slide groove body 322 and a slide groove opening end 321, and the fixed plate guide can be moved out at the slide groove opening end 321, that is, the size of the slide groove opening end is larger than the size of the fixed plate guide.

[0038] In such Figure 6 In a preferred embodiment shown, the telescopic rod includes a first extension rod 43 and a second extension rod 44 slidably disposed inside the first extension rod 43, a mounting block 45 is connected to the end of the second extension rod 44, a first locking bolt 48 for fixing the position of the second extension rod 44 is connected to one side of the first extension rod 43, the first extension rod 43 is slidably disposed inside the fixed rod 42, and a second locking bolt 49 for fixing the position of the first extension rod 43 is connected to one side of the fixed rod 42. By providing a multi-stage length adjustment structure, a longer height adjustment range can be achieved in a smaller height space.

[0039] The strength test of some steel beams requires testing the local strength of the steel beams (with a fixed load area). For test equipment where the lower support force is provided by the load-bearing plate and the pressure device is applied to the upper part of the steel beam, it is impossible to test the local strength of the steel beam. Figure 3 , Figure 4 and Figure 5 A further improved steel beam bearing capacity strength test equipment embodiment is described, the upper part of the bearing plate 30 is provided with a limit block expansion slot 24 (combined with Figure 3 and Figure 4 ), Figure 3 The number of the expansion slots 24 of the middle limit block is four, and the specific number of the expansion slots 24 of the limit block needs to be determined according to the number of local strength test points of the steel beam. Figure 2 and Figure 5As shown); the steel beam bearing capacity strength test equipment also includes a bottom support device 60, which includes a limit block 61, a support block 62, a pressure plate 63, a hydraulic telescopic rod 64, a movable seat 65, a slide rod 66, a translation screw 67 and a screw driver. The limit block 61 is connected to the support block 62, and the limit block and the support rod constitute an assembly, which is installed in the limit block telescopic slot. Specifically, in order to prevent the assembly from falling from the limit block telescopic slot, it is necessary to make the size of the support rod smaller than the limit block telescopic slot, and the size of the limit block larger than the limit block telescopic slot. When the limit block telescopic slot is a square structure, the side length of the square structure of the limit block is smaller than the side length of the limit block telescopic slot. The pressure plate 63, hydraulic telescopic rod 64 and moving seat 65 are connected in sequence from top to bottom. The moving seat is provided with two through holes spaced apart from each other, at least one of which is provided with a threaded structure (i.e., the moving seat 65 is provided with a threaded structure corresponding to the translation screw 67). The slide rod 66 and the translation screw 67 are arranged parallel to each other, and the moving seat 65 is arranged on the slide rod 66 and the translation screw 67; the screw drive and the translation screw are connected, and the screw drive can be a driving motor, and the output shaft of the driving motor is coaxially connected with the translation screw. Figure 5 In the illustrated embodiment, a motor protection box 68 is also illustrated. The motor protection box 68 is disposed outside the drive motor to protect the drive motor.

[0040] The function of the pressure device is to pressurize the upper part of the steel beam to achieve the bearing strength test. Figure 7In a preferred embodiment shown, the pressurizing device 50 includes a frame 51, a lifting mechanism, a connecting rod 54 and a cross bar 53 connected to both ends of the connecting rod 54. The frame is roughly a rectangular frame structure. The frame can be designed separately from the base. In this case, the frame needs to be fixed to the ground or other positions to apply vertical pressure to the steel beam. Or the frame is fixedly connected to the base, such as by setting screw holes at corresponding positions of the frame and the base, and fixing the two with bolts. The use of an integrated connection method can avoid looking for a frame fixing point in the test site, but the use of a split method can test large-sized steel beams or special-shaped steel beams (the test will not be limited to the height of the space formed between the load-bearing plate and the frame for accommodating the steel beam). The crossbar 53 is installed on the frame 51 through a lifting mechanism, and the crossbar 53 moves vertically through the driving of the lifting mechanism. The number of crossbars is preferably two, and the two are arranged parallel to each other at intervals; the connecting rod 54 is connected to four groups of limit plates 55 (arranged in a rectangular shape), and limit slide bars 56 are slidably arranged on the limit plates 55. The bottom ends of the four groups of limit slide bars 56 are connected to the top of the ballast plate 57. The limit slide bars 56 extend out of the top of the limit plate 55 and connect to the limit circular plate. A spring 58 sleeved on the limit slide bar 56 is provided between the limit circular plate and the limit plate 55. The ballast plate squeezes the steel beam, and the limit slide bar slides on the limit plate to squeeze the spring, and the elastic force of the spring reduces the rigid impact between the ballast plate and the steel beam. In another preferred embodiment, the lifting mechanism includes a lifting screw rod 52, a lifting groove for installing the lifting screw rod 52 is provided at the vertical rod of the frame 51, a motor for driving the lifting screw rod 52 to rotate is provided at the bottom of the vertical rod, a screw hole is provided at the end of the cross rod 53 for threading with the lifting screw rod 52, and the end of the cross rod 53 is slidably arranged in the lifting groove. When the steel beam bearing capacity strength test is performed, the pressure strength tester is arranged between the connecting rod (54) and the ballast plate (57).

[0041] The technical features disclosed above are not limited to the disclosed combinations with other features. Those skilled in the art may also make other combinations between the technical features according to the purpose of the invention to achieve the purpose of the invention.
