Description

Technical Field

[0001] The present invention relates to the technical field of building steel structures, and more particularly to a supporting device for building steel structures. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. It is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. It is treated with silanization, pure manganese phosphating, water washing and drying, and galvanizing for rust removal and rust prevention. The various components or parts of the steel structure are usually connected by welds, bolts or rivets. Steel structure is light in weight and simple to construct. It is widely used in large factories, venues, super high-rise buildings, bridges and other fields.

[0003] As a new type of building, steel structure buildings can be made in factories and then installed on site, which effectively shortens the construction period. In addition, steel structures have high strength and good earthquake resistance. Steel can also be reused, effectively reducing construction waste and being more environmentally friendly. Steel structures are prone to rust. Generally, steel structures need to be derusted, galvanized or painted, and maintained regularly.

[0004] When constructing a steel structure building today, support equipment is needed to support and limit the steel structure so that the steel structure maintains a certain height and position to complete the construction work. When supporting the steel structure, the current support equipment can directly support a shorter steel structure. If a longer steel structure is supported, a single support equipment cannot guarantee the support effect, so additional support equipment is needed. However, increasing the support equipment will increase the cost, so the current support equipment cannot be freely adjusted according to the different lengths of steel structures.

[0005] When supporting, the supporting equipment cannot keep the ground in a horizontal state. If the ground is uneven, the supporting equipment cannot maintain a horizontal state and cannot provide effective support. However, the horizontal position adjustment process of today's supporting equipment is relatively complicated, which increases the adjustment time. Summary of the Invention

[0017] Technical effects and advantages of the present invention:

[0018] The present invention can support the steel structure through the upper platform, the right-angle plate and the support frame. A shorter steel structure can be supported by the right-angle plate alone or by the right-angle plate and the support frame on one side. A longer steel structure can also be supported by the right-angle plate and the support frames on both sides. The adjusting wheel can also be rotated to make the movable plate drive the adjusting mechanism and the support frame to move to both sides, thereby supporting a longer steel structure.

[0019] When the drawer is pulled outward relative to the movable outer frame, the limit ring and the limit rod are driven to move outward. When the limit rod moves outward, it moves away from the connecting plate. At this time, the adjustment mechanism as a whole can move relative to the movable mechanism. The connecting plate can be connected to three different limit rods in sequence, so that the position of the adjustment mechanism relative to the movable mechanism changes, thereby changing the travel of the two adjustment mechanisms, making the distance between the two adjustment mechanisms different, and thus adapting to steel structures of different lengths.

[0020] The present invention is placed as a whole on the supporting position, and when the manual wheel is rotated, the bidirectional screw is rotated, thereby causing the first locking plate and the second locking plate to move away from each other. At this time, the serrations of the first locking plate and the second locking plate are separated from the serrations on the side surfaces of the second locking plate, and the semicircular block moves downward under the action of the force and causes the two inclined panels to move to both sides. At this time, under the action of the force, the downward movement distances of the semicircular blocks in the four leveling mechanisms are different, so that the support column is in a vertical state. When the support column is in a vertical state, the manual wheel is rotated in the opposite direction. At this time, the first locking plate and the second locking plate move inward, and the serrations of the first locking plate and the second locking plate lock the inclined panel, keeping the support column in a vertical state, thereby causing the support frame and the right-angle plate to be in a horizontal state.

[0032] The technical solutions of the present invention will be described clearly and completely below in conjunction with the drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The supporting equipment for building steel structures involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] Reference Figure 1 and Figure 2 The present invention provides a supporting device for building steel structures, including an arc-shaped base 1, the top of the arc-shaped base 1 is fixedly connected to a supporting column 2, the bottom end of the side surface of the supporting column 2 is fixedly connected to a lower supporting rib 6, the bottom end of the lower supporting rib 6 is fixedly connected to a vertical rod 7, and the bottom end of the vertical rod 7 is movably connected to a leveling mechanism 8, the middle part of the side surface of the supporting column 2 is fixedly connected to an upper supporting plate 3, the top of the upper supporting plate 3 is fixedly connected to a moving mechanism 4, the top of the moving mechanism 4 is movably connected to an adjusting mechanism 5, and the top of the adjusting mechanism 5 is fixedly connected to a supporting frame 11, the four sides of the supporting column 2 are fixedly connected to the upper supporting plate 3 and the lower supporting rib 6, the top of the supporting column 2 is fixedly connected to an upper platform 9, and the four corners of the top of the upper platform 9 are fixedly connected to right-angle plates 10, and the inner distance between the two right-angle plates 10 close to each other is the same as the inner distance between the support frames 11 on the corresponding sides of the supporting column 2.

[0034] In the embodiment of the present application, the upper platform 9, right-angle plate 10 and support frame 11 of the present application can support the steel structure, and the four sides of the support column 2 are connected to the upper support plate 3 and the lower support rib 6, and the four corners above the upper platform 9 are provided with a right-angle plate 10. Therefore, the two support frames 11 and the right-angle plate 10 in the same direction can support the straight steel structure, and the four support frames 11 and all the right-angle plates 10 can support the cross-structured steel structure. Therefore, the present application can support more types of steel structures. The lower support rib 6 can support the support column 2, and the vertical rod 7 and the support column 2 are both in a vertical state to ensure stability during support. In addition, it should be noted that when the leveling mechanism 8 is supporting, the ground where the leveling mechanism 8 is located needs to be leveled, and the leveling mechanism 8 is kept in a horizontal state with the ground to improve stability during support. The support column 2 itself can be adjusted in height. This is a conventional technical means in this field. This application does not make detailed limitations on its structure. The support column 2 itself can be adjusted in height.

[0035] Reference Figure 2 and Figure 3 The moving mechanism 4 includes a fixed frame 401 fixedly connected to the upper support plate 3. A sliding groove is provided inside the fixed frame 401 for the moving plate 402 to move. The internal thread of the moving plate 402 is connected to a threaded rod 403. The side of the threaded rod 403 is fixedly connected to an adjusting wheel 404. The top of the moving plate 402 is fixedly connected to a linkage plate 405. The top of the linkage plate 405 is fixedly connected to the adjusting mechanism 5.

[0036] In an embodiment of the present application, when the steel structure is placed above the support frame 11 and the right-angle plate 10, rotating the adjustment wheel 404 will drive the threaded rod 403 to rotate. At this time, the movable plate 402 will drive the adjustment mechanism 5 to move through the linkage plate 405, thereby changing the position of the adjustment mechanism 5 and the support frame 11 above it, thereby adapting to steel structures of different lengths.

[0037] Reference Figure 3 、 Figure 4 as well as Figure 5The adjusting mechanism 5 includes a connecting plate 502 fixedly connected to the adjusting mechanism 5, and a movable outer frame 501 is movably connected to the side of the connecting plate 502. The bottom end of the movable outer frame 501 contacts the top end of the fixed frame 401 and the movable outer frame 501 can move relative to the fixed frame 401. A limiting hole is provided on the side of the connecting plate 502, and a limiting rod 503 is movably connected in the limiting hole of the connecting plate 502. The limiting rod 503 is fixedly connected to a pull-out member 504 on the side away from the connecting plate 502. The side of the connecting plate 502 is fixedly connected to a limiting ring 50 5. The side of the limiting ring 505 away from the connecting plate 502 is movably connected to the support spring 506, and the support spring 506 is movably sleeved on the side of the limiting rod 503. The interior of the movable outer frame 501 is provided with three avoidance holes for the limiting ring 505 and the limiting rod 503 to move, and the interior of the movable outer frame 501 is provided with three avoidance holes. The three avoidance holes are all provided with the limiting rod 503 connected to the connecting plate 502. The mechanical structures in the three avoidance holes are the same, and the three avoidance holes are distributed at both ends and the middle of the same side of the movable outer frame 501.

[0038] In the embodiment of the present application, after the drawer 504 is pulled outward, the limit rod 503 and the limit ring 505 are pulled outward, and the limit ring 505 compresses the support spring 506. After the limit rod 503 is removed from the limit hole of the connecting plate 502, the movable outer frame 501 and the connecting plate 502 can move relative to each other. When the movable outer frame 501 moves, two movable outer frames 501 are selected to move in the same direction according to the length of the steel structure. If the steel structure is short, two movable outer frames 501 are selected to move inward. Move, and make the two limit rods 503 farthest away from each other in the two movable outer frames 501 enter the limit holes of the connecting plate 502. At this time, the two movable outer frames 501 move inward synchronously, so that the movable outer frames 501 move within a closer distance. When the steel structure is longer, the two limit rods 503 closest to each other in the two movable outer frames 501 enter the limit holes of the connecting plate 502. The present application can adapt to a wider range of steel structure lengths, and moving the two movable outer frames 501 inward can save occupied space.

[0039] Reference Figures 6-10The leveling mechanism 8 includes a supporting box 801 that can be supported. The first locking plate 802 and the second locking plate 803 are movably connected inside the supporting box 801. The first locking plate 802 and the second locking plate 803 are movably connected inside with an inclined plate 809. There are two inclined plates 809. The two inclined plates 809 are symmetrically distributed at the center of the first locking plate 802 and the second locking plate 803. The inner sides of the two inclined plates 809 are movably connected with a semicircular block 810. The inclined plates 809 are close to each other. The side is provided with a slide groove adapted to the semicircular block 810, and the side of the two inclined panels 809 close to each other is provided with a ten-degree inclined surface. Both sides of the inclined panel 809 and the inner sides of the first locking plate 802 and the second locking plate 803 are provided with mutually adapted serrations. The interiors of the first locking plate 802 and the second locking plate 803 are both threadedly connected with a bidirectional screw 804. One side of the bidirectional screw 804 is fixedly connected to a manual wheel 805, and the other side of the bidirectional screw 804 is fixedly connected to a gear set 806. The side of the wheel group 806 away from the bidirectional screw 804 is fixedly connected to the driven screw 808, and the side of the driven screw 808 is threadedly connected to the inner side of the first locking plate 802 and the second locking plate 803. The sides of the inclined plates 809 away from each other are fixedly connected to the connecting rod 811, and the connecting rod 811 is movably connected to the side of the limiting cylinder 812 away from the inclined plate 809. The side of the connecting rod 811 and the limiting cylinder 812 is movably connected with a top pressure spring 813, and the top pressure spring 813 is away from the connecting rod 811. The side is fixedly connected to the interior of the support box 801, and a partition plate 807 is fixedly connected to the side of the support box 801 near the gear group 806. The first locking plate 802 and the second locking plate 803 are located on the side of the partition plate 807 away from the gear group 806. The first locking plate 802 and the second locking plate 803 are mirror-symmetrical about the inclined plate 809. The bidirectional screw 804 is provided with two thread grooves with opposite rotation directions, and the first locking plate 802 and the second locking plate 803 move toward and away from each other when moving.

[0040] In the embodiment of the present application, the first locking plate 802 and the second locking plate 803 can move in the support box 801, and the bidirectional screw 804 is provided with two thread grooves with opposite rotation directions, such as Figure 9As shown in the driven screw 808 of the parts inside, the first locking plate 802 and the second locking plate 803 move toward and oppositely when they move. Therefore, when the first locking plate 802 and the second locking plate 803 move toward each other and contact the inclined plate 809, the inclined plate 809 will be fixed, and the semicircular block 810 is located in the sliding groove of the inclined plate 809. At this time, the semicircular block 810 is supported, and the top end of the semicircular block 810 is fixedly connected to the bottom end of the vertical rod 7 with the vertical rod 7. The diameter of the bottom end of the vertical rod 7 is smaller than the diameter of the top end of the semicircular block 810, so the semicircular block 810 will not fall off the inclined surface. When the first locking plate 802 and the second locking plate 803 move apart, the first locking plate 802 and the second locking plate 803 will separate from the inclined plate 809. At this time, when the semicircular block 810 moves downward in the inclined plate 809, the two inclined plates 809 will move away from each other. When the two inclined plates 809 move away from each other, the top pressure spring 813 will be compressed. When the semicircular block 810 moves upward, the compressed top pressure spring 813 will reset the inclined plates 809, so that the inclined plates 809 move closer together. 09 moves, the semicircular block 810 moves up and down in the inclined plate 809, thereby making the entire device in a vertical state. When it is in the vertical state, the driven screw 808 is rotated in the opposite direction, the first locking plate 802 and the second locking plate 803 will approach each other, and the saw teeth will mesh with each other to fix the inclined plate 809 to complete the leveling work, avoiding the problem that when traditional leveling equipment is working, each support leg needs to be slowly adjusted, which makes the work efficiency relatively slow. The gear set 806 is a three-gear set, connecting the bidirectional screw 804 and the driven screw 808. The bidirectional screw 804 and the driven screw 808 are connected. The movable screw 808 rotates synchronously, driving the first locking plate 802 and the second locking plate 803 to move on both sides, thereby increasing stability during movement, and the partition plate 807 separates the second locking plate 803 from the gear set 806 to prevent the two from contacting each other and being damaged during movement. In addition, it should be noted that there is sufficient space in the support box 801 for the first locking plate 802 and the second locking plate 803 to separate from the inclined plate 809 when they move away from the inclined plate 809. When the semicircular block 810 moves to the bottom, the inclined plate 809 still does not contact the bidirectional screw 804 and the driven screw 808.

[0041] When the support column 2 is in the vertical position, the semicircular block 810 with a higher horizontal height is subjected to greater pressure from the lower support rib 6 and the vertical rod 7. At this time, the semicircular block 810 will move downward and cause the inclined plates 809 on both sides of the semicircular block 810 to move outward. When the inclined plates 809 move outward, the top pressure spring 813 will be compressed.

[0042] When the inclined plate 809 moves, the manual wheel 805 is rotated in the opposite direction. When the manual wheel 805 rotates in the opposite direction, the first locking plate 802 and the second locking plate 803 move inward synchronously. When the first locking plate 802 and the second locking plate 803 move inward, the serrations on the inner sides of the first locking plate 802 and the second locking plate 803 engage with the serrations on the inclined plate 809. At this time, the first locking plate 802 and the second locking plate 803 will lock the inclined plate 809, keeping the inclined plate 809 in place. When the position of the inclined plate 809 is locked, the position of the semicircular block 810 is fixed, thereby keeping the support column 2 in a vertical state, and the right-angle plate 10 and the support frame 11 in a horizontal state.

[0043] When the right-angle plate 10 and the support frame 11 are kept in a horizontal state, the adjustment mechanism 5 is adjusted according to the length of the steel structure, and the drawer 504 is pulled outward. When the drawer 504 is pulled outward, the limit rod 503 and the limit ring 505 are pulled outward. At this time, the limit rod 503 is removed from the limit hole of the connecting plate 502. At this time, the movable outer frame 501 can be moved. According to the length of the steel structure, the two movable outer frames 501 are selected to move in the same direction. If the steel structure is shorter, the two movable outer frames 501 are selected to move inward, and the two limit rods 503 farthest away from each other in the two movable outer frames 501 enter the limit holes of the connecting plate 502. When the steel structure is longer, the two limit rods 503 closest to each other in the two movable outer frames 501 enter the limit holes of the connecting plate 502 to adapt to steel structures of different lengths;

[0044] After the adjustment mechanism 5 is adjusted, the adjustment wheel 404 can be rotated. When the adjustment wheel 404 is rotated, the threaded rod 403 is rotated and drives the movable plate 402 to move. When the movable plate 402 moves, the adjustment mechanism 5 is driven to move as a whole through the linkage plate 405 to further adjust the position of the adjustment mechanism 5. The present application can adapt to more steel structures. At this time, the steel structure is placed in the support frame 11 above the adjustment mechanism 5 and in the right-angle plate 10 above the movable mechanism 4 to support the steel structure. In addition, it should be noted that the support column 2 itself can be adjusted in height, which is a conventional technical means in this field. This application does not provide a detailed description of its structure. Therefore, the support column 2 of this application can be adjusted in height and can be lowered and removed in time after support.

[0045] Finally: The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
