Technical Field

[0001] The utility model relates to the field of detection devices, in particular to a detection device for the connection strength of a steel structure of a house. Background Art

[0002] The connection strength of the steel structure of a house refers to the firmness of the connection between the steel structure components, which directly affects the overall structural safety of the house. In construction projects, the detection of the connection strength of the steel structure is a very important task, which can help ensure the structural stability and safety of the house.

[0003] After searching, Chinese patent announcement number: CN218725236U discloses a housing steel structure connection strength detection device, including a box body, wherein a sliding assembly is arranged on the outer side of the lower end of the inner part of the box body. The utility model adopts the above structure, inserts the detection piece into the bracket, and fixes the detection piece in the bracket through the pressing assembly, then moves the support downward through the hydraulic cylinder to fit the detection piece, and then makes the pull plate sleeve on the outer wall of the detection piece through the adjustment assembly, and then the hydraulic cylinder can press the detection piece through the support, or drive the support upward to make the pull plate play the role of pulling the detection piece, and then the pressure value is measured by the pressure sensor to detect the strength of the steel structure, and when the detection piece is deformed, the base can be moved closer to the middle position through the sliding assembly, and the bracket can be rotated following the deformation direction of the detection piece through the rotating assembly, thereby avoiding affecting the detection result of the detection piece and improving the accuracy of the steel structure strength detection.

[0004] This device improves the accuracy of steel structure strength detection through sliding components and rotating components, but the sliding components are unstable and cannot ensure that the steel structure is fixed in the center of the box, which will lead to inaccurate detection results. Secondly, there is no protective plate in front of the box, which cannot protect the waste chips flying forward. Therefore, a house steel structure connection strength detection device is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a house steel structure connection strength detection device, which aims to improve the problem in the prior art that when fixing steel structures of different sizes, it is impossible to ensure that they are in the center position of the box, and the protection effect is poor and cannot block the waste chips flying in front.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a device for detecting the connection strength of a steel structure of a house, comprising an outer shell, a base being slidably connected to the bottom end of the outer shell, a clamping seat being slidably connected to the outer wall above the base, a clamping assembly being rotatably connected to the inner wall of the clamping seat, a threaded rod b being rotatably connected to the inner wall of the outer shell, a knob b being fixedly connected to the end of the threaded rod b, two sets of threaded sleeves being threadedly connected to the outer wall of the threaded rod b, and a bracket being hinged to the outer wall of the threaded sleeve.

[0008] A hydraulic cylinder is arranged at the top of the shell, a connecting block is fixedly connected to the lower outer wall of the hydraulic cylinder, and a protective plate is fixedly connected to the end of the connecting block.

[0009] As a further description of the above technical solution:

[0010] The clamping assembly comprises a threaded rod a, a knob a is arranged at the top of the threaded rod a, a clamping block is threadedly connected to the outer wall of the threaded rod a, and a guide rod is fixedly connected to the inner wall of the clamping seat.

[0011] As a further description of the above technical solution:

[0015] As a further description of the above technical solution:

[0016] The outer wall of the guide rod is slidably connected to the inner wall of the clamping block.

[0017] The utility model has the following beneficial effects:

[0018] 1. In the utility model, by setting the knob b, when it is necessary to fix steel structures of different sizes, the knob b is turned to rotate the threaded rod b, so that the two groups of threaded sleeves are moved closer to or separated from each other, which drives the angle of the bracket to change and pulls the two groups of bases to move closer to or separate from each other, so as to fix steel structures of different sizes and ensure that the steel structure is fixed at the center of the box to improve the accuracy of detection.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1-Figure 3 The utility model provides an embodiment: a device for detecting the connection strength of a steel structure of a house, comprising a shell 1, a base 2 is slidably connected to the bottom end of the shell 1, a clamping seat 3 is slidably connected to the outer wall above the base 2, the upper clamping seat 3 can only slide slightly, and slides with the bending of the steel when detecting the connection strength of the steel structure to prevent the clamping seat 3 from being damaged during the bending process, and the base 2 drives the clamping seat 3 to slide so that steel structures of different sizes can be fixed, the inner wall of the clamping seat 3 is rotatably connected to a clamping assembly, the clamping assembly comprises a threaded rod a4, a knob a11 is provided at the top of the threaded rod a4, rotating the knob a11 can drive the threaded rod a4 to rotate, the outer wall of the threaded rod a4 is threadedly connected to a clamping block 5, the inner wall of the clamping seat 3 is fixedly connected to a guide rod 6, the outer wall of the guide rod 6 is slidably connected to the inner wall of the clamping block 5, and the guide rod 6 ensures that the clamping block 5 moves in the vertical direction without offset. Therefore, when the threaded rod a4 rotates, the clamping block 5 can be moved in the vertical direction to clamp the steel structure. The inner wall of the shell 1 is rotatably connected to the threaded rod b7. The end of the threaded rod b7 is fixedly connected to the knob b10. Turning the knob b10 can drive the threaded rod b7 to rotate. The outer wall of the threaded rod b7 is threadedly connected to two groups of threaded sleeves 9. The inner walls of the two groups of threaded sleeves 9 are set as reverse threads. As the threaded rod b7 rotates, they move closer to or separate from each other. The outer wall of the threaded sleeve 9 is hinged with a bracket 8. The end of the bracket 8 is hinged to the inner outer wall of the base 2. The two groups of threaded sleeves 9 move closer to or separate from each other, which will cause the angle of the bracket 8 to shift, thereby pulling the base 2 to slide along the bottom slide groove of the shell 1, adjusting the distance between the two groups of clamping seats 3, and fixing steel structures of different sizes.

[0027] Reference Figure 1-Figure 3A hydraulic cylinder 12 is provided at the top of the shell 1. After the steel structure is fixed, the hydraulic cylinder 12 is lowered to test its strength. The hydraulic cylinder 12 is fixedly connected to a connecting block 14 on the lower outer wall. The lowering of the hydraulic cylinder 12 drives the connecting block 14 to descend together. A protective plate 13 is fixedly connected to the end of the connecting block 14. The side wall of the protective plate 13 is slidably connected to the inner wall of the shell 1. The connecting block 14 drives the protective plate 13 to slide along the inner wall groove of the shell 1 and descend to prevent the steel structure from breaking and waste chips from splashing, causing safety problems for the staff, and the protection is more stringent.

[0028] Working principle: adjust the distance between the two groups of clamping seats 3 according to the size of the steel structure, turn the knob b10 to rotate the threaded rod b7, so that the two groups of threaded sleeves 9 are moved closer to or separated from each other, causing the angle of the bracket 8 to be offset, and pull the two groups of bases 2 to slide along the bottom slide groove of the shell 1. After adjusting to the appropriate position, place the steel structure on the clamping seat 3, rotate the knob a11 to drive the threaded rod a4 to rotate, so that the clamping block 5 moves in the vertical direction along the guide rod 6 to fix the steel structure. After fixing, start the hydraulic cylinder 12. During the descent of the hydraulic cylinder 12, the protective plate 13 is driven to descend along the inner wall of the shell 1, completely wrapping the detection mechanism to prevent waste chips from splashing when the steel structure breaks, thereby ensuring the safety of the staff. During the bending of the steel structure, the clamping seat 3 will move toward the center along the slide groove above the base 2 as the steel structure bends, thereby improving the accuracy of the detection.
