Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a temporary steel column for fixing a scaffold wall connecting piece. BACKGROUND

[0002] In the current construction field, the fixing method of the outer scaffold has obvious shortcomings. In the traditional process, the outer scaffold is fixed by throwing support, or the outer scaffold is connected with the formwork support together in violation of regulations. This method not only exposes significant hidden dangers in various safety inspections and is difficult to meet the specification requirements, but also has great risks in construction safety. In contrast, the new construction scheme provides a compliant fixing fulcrum for the outer scaffold wall connecting piece by pre-burying steel columns and steel diagonal braces in the structure construction stage, connecting each steel column with a steel beam, and welding a steel pipe on the steel beam. The steel used in this scheme can be recycled and reused, and the cost is controllable. Compared with the traditional throwing support method or the illegal connection method, not only the construction safety is greatly improved, but also the overall appearance of the construction site is optimized, which can better meet the specification requirements and quality standards of modern building construction.

[0003] Although the temporary steel column used in the construction site at present can meet the fixing operation requirements of the scaffold wall connecting piece, in the actual application process, such temporary steel columns made by welding have significant use limitations: since the connection structure depends on the welding process, it must be welded and fixed on site each time it is put into use, and the welding points need to be cut and removed after the operation is completed. This repeated welding and removal process not only consumes a large amount of labor cost, because the welder needs to repeatedly perform welding operations, and professional personnel need to use cutting equipment to process the welding interface during removal, which increases the labor input; moreover, it seriously occupies the key construction time, especially in projects with tight schedules, frequent welding waiting and removal operations will cause the process connection to have faults, which will disrupt the original construction rhythm. Over time, the turnover efficiency of the temporary steel column is greatly reduced, which cannot realize rapid installation and reuse, and is also difficult to adapt to the requirements of modern construction for efficient and flexible operation, which indirectly restricts the progress of the overall construction progress, and thus the use efficiency and turnover rate of the temporary steel column are low.

[0021] Please refer to Figure 1 - Figure 9 As shown in the figure, the outer surface of the sliding block 12 is slidably connected to the inner wall of the sliding groove 2, the middle of the sliding block 12 is threadedly connected to the outer surface of the threaded rod 13, the outer surface of the threaded rod 13 is rotatably connected to the inner wall of the rotating groove 3, the rotating groove 3 penetrates through both sides of the sliding groove 2, the middle of the limiting disc 15 is fixed to one end of the threaded rod 13, the outer surface of the limiting disc 15 is rotatably connected to the inner wall of the rotating groove 3, the vertical cross section of the sliding block 12 is in the shape of a Chinese character "zhong", the proximal end of each of the two stabilizing rods 11 is fixed to the two ends of the sliding block 12, the outer surface of each of the two stabilizing rods 11 is rotatably connected to the lower end of each of the two steel diagonal braces 10, the other end of each of the two steel diagonal braces 10 is rotatably connected to one side of each of the two support rods 9, the outer surface of the other side of each of the two support rods 9 is rotatably connected to one end of each of the two column bodies 7, the vertical cross section of each of the two support rods 9 is in the shape of H, the other end of each of the two column bodies 7 is rotatably connected to the outer surface of the connecting rod 6, both ends of the connecting rod 6 are fixed to one end of the pre-embedded seat 1, and the horizontal cross section of the pre-embedded seat 1 is in the shape of U.

[0022] The specific implementation process is as follows: the hand wheel 14 is rotated by manpower to perform rotating operation, so that the threaded rod 13 fixedly connected to the middle of the hand wheel 14 is synchronously rotated. Since the limiting disc 15 fixedly connected to the other end of the threaded rod 13 is limited in the rotating groove 3, stable rotating constraint is formed, so that the threaded rod 13 can maintain axial stable rotating state; under the rotating action of the threaded rod 13, the sliding block 12 threadedly connected to the outer surface of the threaded rod 13 is limited and guided by the sliding groove 2 to stably and linearly slide along the sliding groove 2. During the sliding process, the two stabilizing rods 11 fixedly connected to the middle of the two ends of the sliding block 12 are synchronously translated to drive the lower end of the steel diagonal brace 10 sleeved on the outer surface of the stabilizing rod 11 to move; When the lower end of the steel diagonal brace 10 is displaced, the upper end of the column body 7 will move through the support rod 9, and the column body 7 will rotate around the connecting rod 6 as the rotating shaft, and the two ends of the connecting rod 6 are fixed to one end of the embedded seat 1, so that the upper end of the column body 7 rotates around the connecting rod 6 as the center and its length as the radius, and flips in the direction away from the hand wheel 14. Through this series of linkage, the steel diagonal brace 10 drives the column body 7 to complete the flipping action through the support rod 9: it can fold the column body 7, the steel diagonal brace 10 and the embedded seat 1 into a compact planar state, which is convenient for storage and transportation; it can also be quickly unfolded into a stable support shape to meet the fixing needs of the scaffold wall connecting piece, realize the effect of efficient use, save the cumbersome process of repeated welding and removal of traditional steel columns, not only greatly shorten the installation and storage time, avoid the waste of time during operation, but also significantly improve the use efficiency and turnover rate of temporary steel columns through the efficient folding and unfolding function.

[0023] Embodiment two In the installation process of the temporary steel column, if the embedded plate is simply embedded in the installation foundation, due to the smooth surface of the embedded plate, the contact friction with the surrounding foundation material is insufficient, and it is easy to be displaced under subsequent stress or external disturbance. This displacement not only damages the installation accuracy of the temporary steel column, but also directly weakens the overall support stability, and even may cause safety hazards. Therefore, in order to avoid the above problems, it is necessary to increase the friction between the embedded plate and the foundation through targeted design, improve the friction resistance between them, so as to effectively limit the displacement of the embedded plate, ensure that the temporary steel column can maintain a stable installation posture when bearing stress, and guarantee the stability and safety of the overall structure from the basic level.

[0024] Please refer to Figure 1 - Figure 9 As shown in the figure, the function of stable support is added on the basis of embodiment one; Please refer to Figure 1 - Figure 9As shown, the middle of the lower end of the slider 12 is fixed with a fixed block 16, the other end of the fixed block 16 is rotatably connected with an upper connecting rod 17, the middle of the upper connecting rod 17 is fixed with a connecting frame 18, the other end of the connecting frame 18 is fixed with a lower connecting rod 19, the outer surface of the lower connecting rod 19 is slidably connected with a sliding plate 20, the middle of the sliding plate 20 is provided with a limiting groove 21, the middle of the limiting groove 21 is provided with a guide groove 22, the lower end of the sliding plate 20 is fixed with a plurality of connecting cones 23, the both sides of the sliding plate 20 are provided with a plurality of through grooves 24, the outer surface of the fixed block 16 is slidably connected in the inner wall of the through groove 4, the vertical cutting surface of the fixed block 16 is provided in a U shape, the upper end of the fixed block 16 is fixed in the middle of the lower side of the slider 12, the lower end of the fixed block 16 is rotatably connected on the both sides of the upper connecting rod 17, the middle of the upper connecting rod 17 is fixed on the upper end of the connecting frame 18, the lower end of the connecting frame 18 is fixed in the middle of the lower connecting rod 19, the outer surface of the connecting frame 18 is slidably connected in the inner wall of the limiting groove 21, the outer surface of the lower connecting rod 19 is slidably connected in the inner wall of the guide groove 22, the length of the guide groove 22 is less than the length of the through groove 4, the outer surface of the sliding plate 20 is slidably connected in the inner wall of the seat groove 5, the seat groove 5 penetrates in the lower side of the embedded seat 1.

[0025] The specific implementation process is as follows: the hand wheel 14 is rotated by manpower to perform rotating operation, so that the threaded rod 13 fixedly connected with the middle of the hand wheel 14 is synchronously rotated. Under the rotating action of the threaded rod 13, the slider 12 threadedly connected with the outer surface thereof is stably slid along the sliding groove 2 limited and guided by the sliding groove 2. The sliding slider 12 drives the fixed block 16 fixed in the middle of the lower end to move synchronously, and since the fixed block 16 is limited in the through groove 4, it can maintain a stable sliding state; the moving fixed block 16 drives the upper connecting rod 17 rotatably connected with the lower end to move, and the upper connecting rod 17 drives the lower connecting rod 19 fixedly connected with the other end to move through the connecting frame 18 fixedly connected with the middle. Under the cooperation and restraint of the limiting groove 21 and the guide groove 22, the lower connecting rod 19 drives the sliding plate 20 to slide along the seat groove 5; It is worth noting that the lengths of the both ends of the guide groove 22 are shorter than the length of the through groove 4, and this design provides key stroke control for subsequent actions: when the fixed block 16 moves away from the column body 7, the temporary steel column is in a gradually unfolded state; when the lower connecting rod 19 moves to the edge of the guide groove 22 away from the column body 7, the continuous sliding of the fixed block 16 will drive the sliding plate 20 to move downward in the seat groove 5 through the lower connecting rod 19, and the downward moving sliding plate 20 drives the plurality of connecting cones 23 fixedly connected with the lower end to extend downward, thereby increasing the friction between the embedded seat 1 and the foundation and improving the overall stability; conversely, when the fixed block 16 moves towards the column body 7, the temporary steel column is gradually folded; when the lower connecting rod 19 moves to the edge of the guide groove 22 close to the column body 7, the continuous sliding of the fixed block 16 will drive the sliding plate 20 to move upward in the seat groove 5 through the lower connecting rod 19, and the upward moving sliding plate 20 drives the connecting cones 23 to be automatically stored; The linkage design realizes the extension and folding of the column while automatically completing the extension and storage of the connecting cone 23 through the orderly cooperation of the mechanical structure, which not only guarantees the friction requirement in use, but also avoids additional operation steps, realizes the effect of stable support, effectively limits the displacement of the embedded plate, ensures that the temporary steel column can maintain a stable installation posture when bearing stress, and guarantees the stability and safety of the overall structure from the basic level.

[0026] Embodiment three Since the embedded plate is buried in the installation foundation for a long time, its surface is easy to attach impurities such as soil and sand, and manual cleaning is required before and after each use, which not only increases additional operation steps, but also is difficult to realize automatic operation. Therefore, a matching automatic cleaning structure needs to be designed to simultaneously complete the removal of surface impurities during the expansion or storage of the temporary steel column, thereby eliminating the manual cleaning link and significantly improving the use convenience of the temporary steel column.

[0027] Please refer to Figure 1 - Figure 9 As shown in the figure, the automatic cleaning function is added based on embodiment one; Please refer again to Figure 1 - Figure 9 As shown in the figure, the upper side of both ends of the sliding block 12 is fixed with an upper connecting block 25, the upper end of the two upper connecting blocks 25 is fixed with a cleaning frame 26, the lower side of both ends of the sliding block 12 is fixed with a lower connecting block 27, the lower end of the two lower connecting blocks 27 is fixed with a support block 28, the other end of the two support blocks 28 is fixed with a protruding block 29, the two sides of the sliding plate 20 are provided with a plurality of recesses 30, the two sides of the seat groove 5 are provided with a stabilizing groove 31, the lower end of the two upper connecting blocks 25 is fixed on the upper side of both ends of the sliding block 12, the upper end of the two upper connecting blocks 25 is fixed on both ends of the cleaning frame 26, the outer surface of the cleaning frame 26 is slidingly connected to the upper surface of the embedded seat 1, the upper end of the two lower connecting blocks 27 is fixed on the lower side of both ends of the sliding block 12, the lower end of the two lower connecting blocks 27 is fixed on the two ends of the two support blocks 28, the outer surface of the two support blocks 28 is slidingly connected to the inner wall of the two stabilizing grooves 31, the proximal end of the two support blocks 28 is fixed to the lower end of the two protruding blocks 29, and the outer surface of the two protruding blocks 29 is in contact with the inner wall of the plurality of recesses 30. The vertical cutting surface of each protruding block 29 is arranged in a semicircular shape.

[0028] The specific implementation process is as follows: manual rotation of the hand wheel 14 is performed for rotation operation, so that the threaded rod 13 fixedly connected to the middle part of the hand wheel 14 rotates synchronously. Under the rotating action of the threaded rod 13, the sliding block 12 threadedly connected to the outer surface of the threaded rod 13 is guided and positioned by the sliding groove 2, and stably slides along the sliding groove 2; the sliding sliding block 12 drives the two upper connecting blocks 25 fixed on the upper side of both ends to move synchronously, the two upper connecting blocks 25 drive the cleaning frame 26 fixed on the upper end to stably slide on the upper surface of the embedded seat 1, and in the sliding process, the cleaning frame 26 completely scrapes and cleans the impurities such as soil and sand attached to the upper surface of the embedded seat 1; Meanwhile, the two lower connecting blocks 27 fixed at the lower side of the slider 12 move synchronously with the slider 12, and the two supporting blocks 28 fixed at the lower end are moved stably under the limiting constraint of the two stabilizing grooves 31.

This up-and-down movement can shake off the dirt and sand attached to the slider 20 and the connecting cone 23 fixed at the middle of the slider 20, achieving the effect of automatic cleaning without manual cleaning by the staff, bringing convenience to the staff, and further improving the convenience of the temporary steel column.
