Description

Technical Field

[0001] This invention belongs to the field of steel structure installation technology, and specifically relates to a steel structure construction positioning device. Background Technology

[0002] Large factory steel structures typically consist of steel columns, steel beams, and inter-column bracing. During the steel column hoisting process, after adjacent steel columns have been initially positioned, the column spacing between the two columns needs to be corrected. The steel columns must be kept in a stable position before the steel beams, inter-column bracing, and other components are formally connected to ensure that subsequent connection nodes can be smoothly aligned.

[0003] In current construction practices, adjacent steel columns are often connected and positioned using rigid support rods of fixed length. However, since adjacent steel columns may have slight tilts after initial installation, and the two installation positions may not perfectly correspond, directly connecting the rigid support rods to the two columns can easily lead to jamming or additional bending forces due to deviations in the connection angle. Furthermore, the fixed-length rigid support rods are difficult to adapt to different design column spacings and on-site installation deviations. Therefore, we propose a steel structure construction positioning device to solve these problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a steel structure construction positioning device that solves the issues of the rigid support rod's length being unadjustable and its inability to adapt to inclined steel columns.

[0005] This invention is achieved through the following solution: a steel structure construction positioning device, comprising: Two mounting components are detachably connected to two adjacent steel columns, respectively; An adjustable-length support rod is connected between two mounting components. The support rod includes a movable rod and a first screw. The movable rod is screwed onto the outside of the first screw. The two ends of the movable rod and the first screw, which are far apart from each other, are connected to the corresponding mounting components through universal joints. The first screw is rotatably connected to the corresponding universal joint. By rotating the first screw, the movable rod is driven to move, thereby adjusting the length of the support rod.

[0006] A further improvement of the steel structure construction positioning device of the present invention is that the first screw includes an exposed section and a driving section, the moving rod is screwed to the driving section, and the exposed section is connected to the corresponding universal joint; The movable rod is provided with a length ruler on its exterior, and an indicator sleeve is connected to the exposed section. The indicator sleeve is slidably fitted onto the movable rod to indicate the moving distance of the movable rod in conjunction with the length ruler.

[0007] A further improvement of the steel structure construction positioning device of the present invention is that the indicator sleeve is rotatably connected to the exposed section, and the cross-sections of the moving rod and the indicator sleeve are both non-circular and their shapes are set to match each other to prevent relative rotation between the two.

[0008] A further improvement of the steel structure construction positioning device of the present invention is that a retaining fastener is screwed onto the exposed section to abut against the indicating sleeve to prevent the first screw from rotating.

[0009] A further improvement of the steel structure construction positioning device of the present invention is that the mounting component includes a first clamping plate and a second clamping plate, which are respectively clamped to the opposite sides of the corresponding steel column; The mounting component also includes a drive assembly for driving the first clamping plate and the second clamping plate to move toward each other or away from each other.

[0010] A further improvement of the steel structure construction positioning device of the present invention is that the driving component includes a second screw, a screw hole, a limiting rod, and a limiting hole. The second screw is rotatably connected to the first clamping plate / second clamping plate. The screw hole is opened on the second clamping plate / first clamping plate and the second screw is screwed into the screw hole. The limiting rod is fixedly connected to the first clamping plate / second clamping plate. The limiting hole is opened on the second clamping plate / first clamping plate and is slidably sleeved on the limiting rod. By rotating the second screw, the first clamping plate and the second clamping plate can be driven to move towards each other or away from each other.

[0011] A further improvement of the steel structure construction positioning device of the present invention is that there are two limiting rods and two limiting holes, with the two limiting holes located on both sides of the screw hole and the two limiting rods located on both sides of the second screw.

[0012] A further improvement of the steel structure construction positioning device of the present invention is that the first clamping plate and the second clamping plate are both U-shaped, and the first clamping plate and the second clamping plate are fitted around the outside of the corresponding steel column through the U-shaped groove.

[0013] A further improvement of the steel structure construction positioning device of the present invention is that the number of driving components is two, and the two driving components are respectively arranged at opposite ends of the first clamping plate and the second clamping plate.

[0014] A further improvement of the steel structure construction positioning device of the present invention is that a rotating handle is fixedly sleeved at the end of the first screw away from the moving rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses two mounting components that are detachably installed on two adjacent steel columns. A support rod is connected between the two mounting components to establish a column spacing positioning benchmark. By adjusting the length of the support rod, the construction spacing between adjacent steel columns can be adjusted, and the relative positions of the two steel columns are maintained before the steel beam and column support are installed. Furthermore, by setting universal joints between the two ends of the support rod and the corresponding mounting components, the angular deviation between the two mounting components is compensated, and the support rod is prevented from getting stuck due to slight tilting of the steel column.

Detailed Implementation

[0022] To address the problems of fixed length rigid support rods and difficulty in adapting to inclined steel columns, this invention provides a steel structure construction positioning device. The following detailed description, in conjunction with the accompanying drawings, provides further insights into this steel structure construction positioning device.

[0023] See Figures 1-5 As shown, a steel structure construction positioning device includes: Two mounting pieces 2 are detachably connected to two adjacent steel columns 1, respectively; An adjustable support rod 4 is connected between two mounting parts 2. The support rod 4 includes a movable rod 401 and a first screw 402. The movable rod 401 is screwed onto the outside of the first screw 402. The two ends of the movable rod 401 and the first screw 402 that are far apart from each other are connected to the corresponding mounting parts 2 through universal joints 3. The first screw 402 is rotatably connected to the corresponding universal joint 3. By rotating the first screw 402, the movable rod 401 is driven to move, so as to adjust the length of the support rod 4. The movable rod 401 is fixedly connected to the universal joint 3.

[0024] Two mounting pieces 2 are detachably installed on two adjacent steel columns 1 respectively. A support rod 4 is connected between the two mounting pieces 2 to establish a column spacing positioning benchmark. By adjusting the length of the support rod 4, the construction spacing between adjacent steel columns 1 can be adjusted, and the relative position of the two steel columns 1 is maintained before the steel beam and column support are installed. Furthermore, by setting universal joints 3 between the two ends of the support rod 4 and the corresponding mounting pieces 2, the angular deviation between the two mounting pieces 2 is compensated, and the support rod 4 is prevented from getting stuck due to slight tilting of the steel column 1.

[0025] Furthermore, a drive cylinder 407 is fixedly connected inside the movable rod 401, and the drive cylinder 407 is used to screw it onto the first screw 402.

[0026] The first screw 402 includes an exposed section and a drive section. The moving rod 401 is screwed to the drive section and the exposed section is connected to the corresponding universal joint 3. The movable rod 401 is provided with a length ruler 404 on its exterior. An indicator sleeve 403 is connected to the exposed section and can be slidably sleeved on the movable rod 401 to indicate the moving distance of the movable rod 401 in conjunction with the length ruler 404.

[0027] By adopting the above design, when the first screw 402 drives the moving rod 401 to move, the length ruler 404 will move synchronously. The indicator sleeve 403 is fitted on the edge of the length ruler 404 to indicate the reading, which makes it convenient for the operator to adjust the overall length of the support rod 4.

[0028] The indicator sleeve 403 is rotatably connected to the exposed section. The cross-sections of the moving rod 401 and the indicator sleeve 403 are both non-circular and their shapes are designed to fit each other to prevent them from rotating relative to each other.

[0029] Further, see Figure 3As shown, both the moving rod 401 and the indicating sleeve 403 are quadrilateral in shape, and the four corners are rounded. The indicating sleeve 403 is fitted onto the moving rod 401. When the first screw 402 is rotated, the indicating sleeve 403 will not rotate. The moving rod 401 will move laterally under the drive of the screw. The non-rotating indicating sleeve 403 allows for a clearer observation of the dimensions on the length gauge 404, facilitating precise control of the overall length of the support rod 4.

[0030] The indicator sleeve 403 is rotatably connected to the exposed section via a bearing 406.

[0031] Among them, see Figure 2 As shown, a retainer 405 is screwed onto the exposed section to abut against the indicator sleeve 403 to prevent the first screw 402 from rotating.

[0032] By adopting the above design, after adjusting the length of the support rod 4, the indicator sleeve 403 can be tightened by rotating the abutment 405. There is no relative rotation between the moving rod 401 and the universal joint 3. When the abutment 405 is tightened against the indicator sleeve 403, the indicator sleeve 403 and the first screw 402 cannot rotate relative to each other. The indicator sleeve 403 and the moving rod 401 are constrained by the cross-section adaptation and have no relative rotation. Therefore, the reverse constraint prevents the first screw 402 from rotating relative to the universal joint 3 connected to it. In this way, if the first screw 402 is accidentally touched, if the first screw 402 rotates, it will drive the abutment 405 to rotate. However, the abutment 405 and the indicator sleeve 403 are already tightened and fixed, so the first screw 402 will be limited, thereby preventing the first screw 402 from easily rotating due to accidental contact.

[0033] The mounting component 2 includes a first clamping plate 201 and a second clamping plate 202, which are used to clamp onto the opposite sides of the corresponding steel column 1 respectively. Mounting component 2 also includes a drive assembly for driving the first clamping plate 201 and the second clamping plate 202 to move toward each other or away from each other.

[0034] By adopting the above design, the first clamping plate 201 and the second clamping plate 202 are driven to move towards each other using the driving component, so that the first clamping plate 201 and the second clamping plate 202 are respectively clamped to the opposite sides of the corresponding steel column 1, thereby achieving fixation with the steel column 1. The first clamping plate 201 and the second clamping plate 202 are driven to move away from each other using the driving component, so that the first clamping plate 201 and the second clamping plate 202 do not contact the steel column 1. Then, the first clamping plate 201 and the second clamping plate 202 can be removed from the steel column 1 to achieve disassembly, which is convenient and simple to operate.

[0035] Among them, see Figure 5As shown, the driving assembly includes a second screw 203, a screw hole, a limiting rod 204, and a limiting hole. The second screw 203 is rotatably connected to the first clamping plate 201. The screw hole is opened on the second clamping plate 202, and the second screw 203 is screwed into the screw hole. The limiting rod 204 is fixedly connected to the first clamping plate 201. The limiting hole is opened on the second clamping plate 202, and the limiting hole is slidably sleeved on the limiting rod 204. By rotating the second screw 203, the first clamping plate 201 and the second clamping plate 202 can be driven to move towards each other or away from each other.

[0036] Among them, see Figure 5 As shown, there are two limiting rods 204 and two limiting holes. The two limiting holes are located on both sides of the screw hole, and the two limiting rods 204 are located on both sides of the second screw 203.

[0037] By adopting the above design, the limiting hole and the limiting rod 204 are used to limit the movement of the second screw 203, which can drive the second clamping plate 202 to move closer to or further away from the first clamping plate 201, so as to achieve stable movement of the two towards each other or away from each other.

[0038] Furthermore, a rotating cap 206 is fixedly installed at the end of the second screw 203 away from the second clamping plate 202, so that the second screw 203 can be rotated and adjusted by turning the rotating cap 206.

[0039] The first clamping plate 201 and the second clamping plate 202 are both U-shaped, and the first clamping plate 201 and the second clamping plate 202 are fitted around the outside of the corresponding steel column 1 through the U-shaped groove.

[0040] By adopting the above design, the first clamping plate 201 and the second clamping plate 202 of the U shape are respectively clamped at both ends of the steel column 1, and the driving component is used to make the first clamping plate 201 and the second clamping plate 202 be enclosed and sleeved on the steel column 1 through the U-shaped groove, so as to improve the connection stability between the mounting part 2 and the steel column 1.

[0041] Further, see Figure 5 As shown, the steel column 1 is an I-beam. In this embodiment, corner adapter pads 205 are detachably connected to the inner walls of both ends of the second clamping plate 202 and the U-shaped groove of the second clamping plate 202. These pads have a mating surface that fits the corner of the steel column 1 and is used to fill the local gap between the clamping structure and the steel column 1. The corner adapter pads 205 can be prefabricated in various specifications and can be replaced with different thicknesses and mating surface shapes according to the flange thickness or corner shape of the steel column 1.

[0042] The number of driving components is two, and the two driving components are respectively set at opposite ends of the first clamping plate 201 and the second clamping plate 202.

[0043] By simultaneously rotating the second screws 203 on both sides to drive the first clamping plate 201 and the second clamping plate 202, the stability of their movement and adjustment can be ensured.

[0044] Among them, see Figure 2 As shown, a rotating handle 408 is fixedly sleeved on the end of the first screw 402 away from the moving rod 401.

[0045] By setting a rotating handle 408, it is convenient for the operator to manually rotate the first screw 402 for adjustment, avoiding the risk of hand injury from directly holding the first screw 402.
