Description

Technical Field

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

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. A steel structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and is treated with rust removal and rust prevention by silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts of a steel structure are usually connected by welds, bolts or rivets. A steel structure has a relatively light self-weight and simple construction, and is widely used in large factories, stadiums, super high-rise buildings, bridges and other fields; A steel structure building applying a steel structure is a new type of building. Building components can be fabricated in a factory and then installed on site, effectively shortening the construction period. Moreover, a steel structure has a relatively high strength and good seismic resistance, and steel can also be reused, effectively reducing construction waste and being more environmentally friendly. However, a steel structure is prone to corrosion. Generally, a steel structure needs to be derusted, galvanized or painted, and requires regular maintenance; When a current steel structure building is being constructed, a support device needs to be used to support and limit the steel structure so that the steel structure maintains a certain height and position, thereby completing the construction work. When the current support device supports a steel structure, it can directly support a steel structure with a relatively short length. If it supports a steel structure with a relatively long length, a single support device cannot ensure the support effect. Therefore, it is necessary to add support devices, which will increase the cost. Therefore, the current support device cannot be freely adjusted according to steel structures of different lengths; When a support device is performing support, it cannot keep the ground in a horizontal state. If the ground is uneven, the support device cannot maintain a horizontal state, and effective support cannot be performed at this time. Moreover, the horizontal position adjustment process of the current support device is relatively complex, increasing the adjustment time. Summary of the Invention

[0009] In a preferred embodiment, the leveling mechanism includes a support box that can provide support. Inside the support box, a first locking plate and a second locking plate are movably connected. An inclined panel is movably connected inside the first locking plate and the second locking plate.

The connecting plate can be connected to three different limit rods in sequence, so that the position of the adjustment mechanism relative to the moving mechanism changes, thereby changing the stroke of the movement of the two adjustment mechanisms, making the distance between the two adjustment mechanisms different, and then adapting to steel structures of different lengths; The present invention is placed entirely on the support position.

At this time, the saw teeth of the first locking plate and the second locking plate are separated from the saw teeth on the side of the second locking plate, and the semi-circular block moves downward under the action of force and makes the two inclined panels move to both sides. At this time, under the action of force, the distances that the semi-circular blocks in the four leveling mechanisms move downward are different, making the support columns in a vertical state. When the support columns are in a vertical state, the manual rotating wheel is rotated in the reverse direction. At this time, the first locking plate and the second locking plate move inward, and the saw teeth of the first locking plate and the second locking plate lock the inclined panel, keeping the support columns in a vertical state, and then making the support frame and the right-angle plate in a horizontal state.

Specific embodiments

[0025] The technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. In addition, the forms of each structure described in the following embodiments are only examples, and a support device for building steel structures involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] Referring to Figure 1 and Figure 2 , the present invention provides a support device for building steel structures, including an arc-shaped base 1. The top end of the arc-shaped base 1 is fixedly connected with a support column 2. The bottom end of the side of the support column 2 is fixedly connected with a lower support rib 6. The bottom end of the lower support rib 6 is fixedly connected with a vertical rod 7. The bottom end of the vertical rod 7 is movably connected with a leveling mechanism 8. The middle part of the side of the support column 2 is fixedly connected with an upper support plate 3. The top end of the upper support plate 3 is fixedly connected with a moving mechanism 4. The top end of the moving mechanism 4 is movably connected with an adjusting mechanism 5. The top end of the adjusting mechanism 5 is fixedly connected with a support frame 11. The four sides of the support column 2 are fixedly connected with upper support plates 3 and lower support ribs 6. The top end of the support column 2 is fixedly connected with an upper platform 9. Right-angle plates 10 are fixedly connected to the four corners of the top end of the upper platform 9. The inner distance between two adjacent right-angle plates 10 is the same as the inner distance of the support frame 11 on the corresponding side of the support column 2.

[0027] In the embodiment of the present application, the upper platform 9, the right-angle plate 10, and the support frame 11 of the present application can support the steel structure. Upper support plates 3 and lower support ribs 6 are connected to the four sides of the support column 2, and right-angle plates 10 are provided at the four corners above the upper platform 9. Therefore, two support frames 11 and right-angle plates 10 in the same direction can support the linear steel structure, and four support frames 11 and all right-angle plates 10 can support the steel structure of the cross structure. Therefore, the present application can support more types of steel structures. The lower support ribs 6 can support the support column 2, and the vertical rods 7 and the support column 2 are both in a vertical state to ensure the stability during support. In addition, it should be noted that when the leveling mechanism 8 is used for support, the ground where the leveling mechanism 8 is located needs to be leveled to keep the leveling mechanism 8 in a horizontal state with the ground to improve the stability during support. The support column 2 can adjust its own height, which is a conventional technical means in the art, and the present application does not make a detailed limitation on its structure, as long as the support column 2 can adjust its own height.

[0028] Refer to Figure 2 With Figure 3 , the moving mechanism 4 includes a fixed frame 401 fixedly connected to the upper support plate 3. A sliding groove for the movement of the moving plate 402 is provided inside the fixed frame 401. A threaded rod 403 is threadedly connected inside the moving plate 402. An adjusting wheel 404 is fixedly connected to the side of the threaded rod 403. A linkage plate 405 is fixedly connected to the top of the moving plate 402, and the top of the linkage plate 405 is fixedly connected to the adjusting mechanism 5.

[0029] In the embodiment of the present application, when the steel structure is placed above the support frame 11 and the right-angle plate 10, rotating the adjusting wheel 404 will drive the threaded rod 403 to rotate. At this time, the moving plate 402 will drive the adjusting mechanism 5 to move through the linkage plate 405, changing the position of the adjusting mechanism 5 and the support frame 11 above it, so as to adapt to steel structures of different lengths.

[0030] Refer to Figure 3 , Figure 4 And Figure 5, the adjusting mechanism 5 includes a connecting plate 502 fixedly connected to the adjusting mechanism 5. 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 formed in the side of the connecting plate 502, and a limiting rod 503 is movably connected in the limiting hole of the connecting plate 502. A pulling member 504 is fixedly connected to the side of the limiting rod 503 away from the connecting plate 502. A limiting ring 505 is fixedly connected to the side of the connecting plate 502. A support spring 506 is movably connected to the side of the limiting ring 505 away from the connecting plate 502. The support spring 506 is movably sleeved on the side of the limiting rod 503. Three avoiding holes for the limiting ring 505 and the limiting rod 503 to move are formed in the interior of the movable outer frame 501, and three avoiding holes are formed in the interior of the movable outer frame 501. The limiting rod 503 connected to the connecting plate 502 is arranged in each of the three avoiding holes. The mechanical structures of the three avoiding holes are the same, and the three avoiding holes are distributed at both ends and the middle of the same side of the movable outer frame 501.

[0031] In the embodiment of the present application, after the pulling member 504 is pulled outwards, at this time, the limiting rod 503 and the limiting ring 505 are pulled outwards, the limiting ring 505 will compress the support spring 506. After the limiting rod 503 is removed from the limiting hole of the connecting plate 502, the movable outer frame 501 and the connecting plate 502 can move relatively. When the movable outer frame 501 moves, two movable outer frames 501 in the same direction are selected to move according to the length of the steel structure. If the steel structure is short, the two movable outer frames 501 are selected to move inwards, and the two farthest limiting rods 503 in the two movable outer frames 501 enter the limiting holes of the connecting plate 502. At this time, the two movable outer frames 501 move inwards synchronously, so that the movable outer frame 501 moves within a relatively short distance. When the steel structure is long, the two closest limiting rods 503 in the two movable outer frames 501 enter the limiting holes of the connecting plate 502. The steel structure length range that the present application can adapt to is wider, and by moving the two movable outer frames 501 inwards, the occupied space can be saved.

[0032] Refer to Figures 6 - 10, the leveling mechanism 8 includes a support box 801 that can provide support. Inside the support box 801, a first locking plate 802 and a second locking plate 803 are movably connected. Inside the first locking plate 802 and the second locking plate 803, an inclined panel 809 is movably connected. The number of inclined panels 809 is two, and the two inclined panels 809 are symmetrically distributed at the central position of the first locking plate 802 and the second locking plate 803. Inside the two inclined panels 809, a semi-circular block 810 is movably connected. On the side of the inclined panel 809 close to each other, a chute adapted to the semi-circular block 810 is provided, and on the side of the two inclined panels 809 close to each other, a ten-degree inclined surface is provided. On both sides of the inclined panel 809 and on the inner sides of the first locking plate 802 and the second locking plate 803, mutually adapted sawteeth are provided. Inside the first locking plate 802 and the second locking plate 803, a bidirectional screw 804 is threadedly connected. On one side of the bidirectional screw 804, a manual rotating wheel 805 is fixedly connected. On the other side of the bidirectional screw 804, a gear set 806 is fixedly connected. On the side of the gear set 806 away from the bidirectional screw 804, a driven screw 808 is fixedly connected. The side of the driven screw 808 is threadedly connected to the inner sides of the first locking plate 802 and the second locking plate 803. On the sides of the inclined panels 809 away from each other, connecting rods 811 are fixedly connected. On the side of the connecting rod 811 away from the inclined panel 809, a limiting cylinder 812 is movably connected. A pressing spring 813 is movably sleeved on the sides of the connecting rod 811 and the limiting cylinder 812. The side of the pressing spring 813 away from the connecting rod 811 is fixedly connected to the inside of the support box 801. On the side of the support box 801 close to the gear set 806, a partition plate 807 is fixedly connected. 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 set 806. The first locking plate 802 and the second locking plate 803 are mirror-symmetrical with respect to the inclined panel 809. The bidirectional screw 804 is provided with two threaded grooves with opposite helix directions, and when the first locking plate 802 and the second locking plate 803 move, they move towards each other and away from each other.

[0033] In the embodiment of the present application, the first locking plate 802 and the second locking plate 803 can move inside the support box 801, and the bidirectional screw 804 is provided with two threaded grooves with opposite helix directions. For example, 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 slide groove of the inclined plate 809. At this time, the semicircular block 810 will be 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. The inclined plate 809 can support the semicircular block 810. 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 be separated 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 to each other. 09 moves, the semicircular block 810 moves up and down in the inclined plate 809, so that the whole device is in a vertical state. When it is in the vertical state, the driven screw 808 is rotated in the opposite direction, and the first locking plate 802 and the second locking plate 803 are close to each other. At this time, the saw teeth are engaged with each other to fix the inclined plate 809 to complete the leveling work, avoiding the problem that when the traditional leveling equipment is working, each support leg needs to be slowly adjusted, which makes the work efficiency 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 enough 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.

[0034] Working principle of the present invention: Before support is required, rotate the manual rotating wheel 805. When the manual rotating wheel 805 rotates, it drives the bidirectional screw rod 804 to rotate. When the bidirectional screw rod 804 rotates, it drives the first locking plate 802 and the second locking plate 803 to move away from each other. When the first locking plate 802 and the second locking plate 803 move, the sawteeth on their inner sides are separated from the sawteeth on both sides of the inclined panel 809. At this time, place the arc-shaped base 1 and the leveling mechanism 8 in contact with the ground, clean the ground where the leveling mechanism 8 is located, and keep the leveling mechanism 8 in a horizontal state. At this time, directly adjust the support column 2 to be in a vertical state. When the support column 2 is in a vertical state, the semi-circular block 810 with a higher horizontal height receives greater pressure from the lower support rib 6 and the vertical rod 7. At this time, the semi-circular block 810 will move downward and cause the inclined panels 809 on both sides of the semi-circular block 810 to move outward. When the inclined panels 809 move outward, they will compress the top pressure spring 813; When the inclined panel 809 moves, rotate the manual rotating wheel 805 in the reverse direction. When the manual rotating wheel 805 rotates in the reverse direction, it causes the first locking plate 802 and the second locking plate 803 to move inward synchronously. When the first locking plate 802 and the second locking plate 803 move inward, the sawteeth on the inner sides of the first locking plate 802 and the second locking plate 803 are engaged with the sawteeth of the inclined panel 809. At this time, the first locking plate 802 and the second locking plate 803 will lock the inclined panel 809 and keep the position of the inclined panel 809 unchanged. When the position of the inclined panel 809 is locked, the position of the semi-circular 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 are kept in a horizontal state; When the right-angle plate 10 and the support frame 11 are in a horizontal state, adjust the adjusting mechanism 5 according to the length of the steel structure. Pull the pulling member 504 outward. When the pulling member 504 is pulled outward, it drives the limiting rod 503 and the limiting ring 505 to be pulled outward. At this time, the limiting rod 503 moves out of the limiting hole of the connecting plate 502. At this time, the moving outer frame 501 can be moved. Select two moving outer frames 501 in the same direction to move according to the length of the steel structure. If the steel structure is short, then select two moving outer frames 501 to move inward, and make the two farthest limiting rods 503 in the two moving outer frames 501 enter the limiting holes of the connecting plate 502. When the steel structure is long, make the two closest limiting rods 503 in the two moving outer frames 501 enter the limiting holes of the connecting plate 502 to adapt to steel structures of different lengths; After the adjustment mechanism 5 is adjusted, the adjusting wheel 404 can be rotated at this time. When the adjusting wheel 404 rotates, the threaded rod 403 rotates and drives the moving plate 402 to move. When the moving plate 402 moves, it drives the entire adjustment mechanism 5 to move through the linkage plate 405, further adjusting the position of the adjustment mechanism 5. The present application can adapt to more steel structure lengths. At this time, the steel structure is placed in the support frame 11 above the adjustment mechanism 5 and the right-angle plate 10 above the moving mechanism 4 to support the steel structure. In addition, it should be noted that the support column 2 can be adjusted in height by itself, which is a conventional technical means in the art, and the present application does not elaborate on its structure. Therefore, the support column 2 of the present application can be adjusted in height and can be lowered in time after support and removed.

[0035] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
