[0022] In the following, an embodiment of a recyclable edge protection fixing device for stairwells of the present utility model will be described with reference to the drawings.
[0023] The embodiments described herein are specific specific implementation manners of the present utility model for explaining the concept of the present utility model, and are all illustrative and exemplary, and should not be construed as limiting the implementation manners of the present utility model and the scope of the present utility model. Except for the embodiments described herein, those skilled in the art can also adopt other obvious technical solutions based on the content disclosed in the claims and the specification of the present application, and these technical solutions include technical solutions that make any obvious substitutions and modifications to the embodiments described herein.
[0024] The drawings in this specification are schematic diagrams for assisting in explaining the concept of the present utility model, schematically showing the shapes of various parts and their mutual relationships. Please note that in order to clearly show the structures of the components in the embodiments of the present utility model, the drawings are not drawn in the same proportion. The same reference numerals are used to represent the same parts.
[0025] Please refer to Figure 1 - Figure 4As shown in the figure, a recyclable edge protection fixing device for stairwells, including a steel pipe fixing part 1 and a structure fixing part 2. One end of the steel pipe fixing part 1 is provided with a steel pipe collar 11, and the other end of the steel pipe fixing part 1 is provided with a through screw member 12. The steel pipe collar 11 is fixedly connected to the through screw member 12. The structure fixing part 2 includes a steel sheet 21, and a through screw nut 22 is fixedly connected to the top end of the steel sheet 21. Nail holes 23 are provided on both sides of the steel sheet 21. Threads are provided on the outer side of the through screw member 12, and the through screw member 12 is threadedly connected to the through screw nut 22. A hoop mechanism 3 is provided at the top end of the steel sheet 21, and two sets of hoop mechanisms 3 are provided.
[0026] During operation, in the process of using this device, the edge protection steel pipe is preferably sleeved into the steel pipe collar 11 first, and then the through screw member 12 is threadedly connected to the through screw nut 22, so that the steel pipe fixing part 1 and the structure fixing part 2 can be connected. And the distance can be controlled by the number of turns of the thread, which can adapt to the distance between the current stairs and can be installed for multiple sets of stairs with different sizes. When the position of the through screw member 12 is determined, the hoop mechanism 3 can be used to fix the through screw member 12, so that it will not rotate again after installation and fixation, thus preventing the device from being damaged.
[0027] Furthermore, the steel pipe collar 11 and the through screw member 12 are perpendicular to each other. The material model of the steel pipe collar 11 is Q235b steel, and the diameter of the steel pipe collar 11 is 50 mm.
[0028] During operation, the through screw is perpendicular to the steel pipe collar 11 and welded by carbon dioxide gas shielded welding with a full weld bead to form the steel pipe fixing part 1. The steel pipe collar 11 and the through screw member 12 are perpendicular to each other. In this way, when the steel pipe is installed into the steel pipe kit, the steel pipe is also perpendicular to the through screw member 12. Thus, the positions of the mutual components can be accurately determined when installing the device. The steel pipe collar 113 is formed by bending and welding a Q235b conventional steel plate, making it very firm when fixing the steel pipe and preventing the steel pipe from loosening.
[0029] Furthermore, the material model of the steel sheet 21 is Q235b steel. Nail holes 23 are provided on both sides at the top end of the steel sheet 21, and stud nails 24 are provided inside the nail holes 23.
[0030] During operation, the steel sheet 21 is cut from a 3 mm thick Q235b steel plate with an indefinite size. At the same time, the steel sheet 21 is a key component for the overall structure fixing part 2 to be fixed to the corresponding mechanism. By placing the steel sheet 21 on a smooth fixing part and driving two sets of stud nails 24 into the fixing part through the nail holes 23 on both sides of the steel sheet 21, the structure fixing part 2 is fixed to the corresponding fixing part, thus fixing the overall protection device, which is also a key step to ensure the safety of the device.
[0031] Furthermore, the nail holes 23 are symmetric about both sides of the through screw nut 22, and the size of the nail holes 23 is adapted to the size of the stud nails 24.
[0032] During operation, the nail holes 23 are symmetric on both sides of the through-thread nut 22, making the structural fixture 2 aesthetically pleasing and stable after installation. Moreover, the size of the nail holes 23 is adapted to the size of the nail gun nails 24. In this way, when the nail gun nails 24 are driven into the nail holes 23, the steel sheet 21 will not shake and the structural fixture 2 will be stable. At the same time, the nail gun nails 24 will not damage the steel sheet 21, ensuring the integrity of the steel sheet 21 during subsequent recycling.
[0033] Furthermore, the through-thread nut 22 and the through-thread rod member 12 are mutually adapted, and the diameter of the through-thread rod member 12 is the same as the diameter of the inner hole of the through-thread nut 22.
[0034] During operation, the same diameter of the through-thread rod member 12 and the inner hole of the through-thread nut 22 can ensure stable threaded connection between the through-thread rod member 12 and the through-thread nut 22, thereby adjusting the distance between the steel pipe and the structural fixture 2. The mutual adaptation of the through-thread nut 22 and the through-thread rod member 12 prevents the problem of thread slipping between the through-thread rod member 12 and the through-thread nut 22.
[0035] Furthermore, the hoop mechanism 3 includes a first hoop 31. The outer side of the first hoop 31 is sleeved on the bottom end of the through-thread rod member 12. The bottom end of the first hoop 31 is fixedly connected to the steel plate. A second hoop 32 is provided at the top end of the first hoop 31. The second hoop 32 is sleeved on the top end of the through-thread rod member 12, and the first hoop 31 and the second hoop 32 are mutually adapted.
[0036] During operation, after the through-thread rod member 12 and the through-thread nut 22 are threadedly connected and the position is determined, if there is no fixation by the hoop mechanism 3 at this time, the through-thread rod member 12 can rotate freely on the through-thread nut 22, which will cause the overall device to be very unstable. In order to prevent the through-thread rod member 12 from rotating due to external personnel's operation errors or collisions and other operations, resulting in safety problems after the device is installed, the first hoop 31 and the second hoop 32 in the two sets of hoop mechanisms 3 need to be tightly connected. In this way, through the static friction force formed by the first hoop 31 and the second hoop 32 pressing tightly on the through-thread rod member 12, the through-thread rod member 12 can be prevented from rotating freely.
[0037] Furthermore, first holes 311 are formed on both sides of the first hoop 31, and second holes 321 are formed on both sides of the second hoop 32. The diameters of the first holes 311 and the second holes 321 are the same, and the first holes 311 and the second holes 321 are aligned vertically.
[0038] During operation, since the first hoop 31 is fixedly connected to the steel plate, after the threaded rod member 12 and the threaded nut 22 are threadedly connected, the top end of the first hoop 31 is already in close contact with the bottom end of the threaded rod member 12. And the second hoop 32 is one of the detachable parts. At this time, only need to place the second hoop 32 on the first hoop 31 so that the first holes 311 on both sides of the first hoop 31 are aligned with the second holes 321 on both sides of the second hoop 32. This means that the second hoop 32 is installed in the correct position. At the same time, the size of the first holes 311 is the same as that of the second holes 321, which is very convenient for the installation of the screw 33 next. After installation, the second hoop 32 will not shake or become unstable.
[0039] Furthermore, screws 33 are provided inside the first holes 311 and the second holes 321. The size of the screws 33 is adapted to the first holes 311 and the second holes 321. The bottom end of the screw 33 penetrates through the first holes 311 and the second holes 321, and a bolt is threadedly connected to the outside of the threaded bottom end.
[0040] During operation, when the first hoop 31 and the second hoop 32 are placed in alignment, the screw 33 can be passed through the first holes 311 and the second holes 321 from the top end of the second hoop 32. Thread the bolt onto the bottom end of the screw 33 below the first holes 311 and tightly rotate it until it cannot be rotated. At this time, the first hoop 31 and the second hoop 32 are connected, and the first hoop 31 and the second hoop 32 tightly press the threaded rod member 12. Without disassembling the second hoop 32, the threaded rod member 12 cannot be rotated, which ensures the safety of the device.
[0041] Working principle: During the use of this device, the edge protection steel pipe is preferably sleeved into the steel pipe collar 11, and then the through-threaded rod member 12 is threadedly connected with the through-threaded nut 22, so that the steel pipe fixing member 1 and the structure fixing member 2 can be connected. The distance is controlled by the number of turns of the upper thread, and the installation position of the through-threaded rod member 12 is determined by determining the distance between the stairs. When the position of the through-threaded rod member 12 is determined, the hoop mechanism 3 can be used to fix the through-threaded rod member 12. Since the first hoop 31 is fixedly connected to the steel plate, after the through-threaded rod member 12 is threadedly connected with the through-threaded nut 22, the top end of the first hoop 31 is already in close contact with the bottom end of the through-threaded rod member 12, and the second hoop 32 is one of the detachable parts. At this time, only need to place the second hoop 32 on the first hoop 31 so that the first holes 311 on both sides of the first hoop 31 are aligned with the second holes 321 on both sides of the second hoop 32, which means that the installation position of the second hoop 32 is correct. When the first hoop 31 and the second hoop 32 are aligned and placed, the screw 33 can be passed through the first hole 311 and the second hole 321 from the top end of the second hoop 32, and the bolt is threadedly connected to the bottom end of the screw 33 below the first hole 311 and tightly rotated until it cannot be rotated. At this time, the first hoop 31 and the second hoop 32 are connected, and the first hoop 31 and the second hoop 32 tightly press the through-threaded rod member 12. Without disassembling the second hoop 32, the through-threaded rod member 12 cannot be rotated, which ensures the safety of the device. Finally, by placing the steel sheet 21 on the smooth fixing member and driving two groups of nail guns 24 into the fixing member from the nail holes 23 on both sides of the steel sheet 21, the structure fixing member 2 is fixed to the corresponding fixing member, which makes the overall protection device fixed and is also a key step to ensure the safety of the device. After the stairs are built, the above-mentioned nail guns 24, the second hoop 32 and the steel pipe can be removed, and then the through-threaded rod member 12 and the through-threaded nut 22 can be disassembled to disassemble the overall device. Repeat the above work when proceeding to the next project to complete the installation of the device.
[0042] The disclosed technical features are not limited to the combinations with other disclosed features. Those skilled in the art can also make other combinations among the technical features according to the purpose of the utility model, subject to achieving the purpose of the utility model.
