Description

Technical Field

[0001] This utility model relates to the field of cumulative sliding construction technology, and more specifically, to a sliding column sliding positioning device. Background Technology

[0002] The incremental sliding scheme refers to the construction of bridges or large structures by setting up a high-altitude assembly platform on one side of the main structure, using concrete trough beams as side sliding tracks, and erecting a temporary support frame for the middle sliding track on the centerline of the main structure. Then, steel truss components are assembled on the ground and hoisted onto the high-altitude assembly platform to assemble the first sliding unit, which is then connected to a hydraulic synchronous multi-point jacking mechanism. After jacking the first sliding unit, the second sliding unit is assembled and connected to the first sliding unit for the second sliding. This process is repeated until the assembly and sliding of the entire structure are completed.

[0003] During the cumulative sliding process, the sliding column takes a long time and effort to position due to the influence of installation accuracy, synchronization control accuracy and measurement errors, which greatly increases the on-site construction time and construction cost, and the positioning accuracy cannot be guaranteed.

[0033] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0034] like Figures 1-5 As shown in the figure, the sliding column positioning device proposed in this embodiment can be used to assist in the positioning of sliding columns during sliding construction, and can also assist in the sliding positioning of other components.

[0035] Typically, a sliding track is installed on a concrete foundation, and the sliding column 3 slides along the sliding track to reach the desired position. The sliding column positioning device provided by this utility model can assist the sliding column 3 in accurately and conveniently positioning itself. This sliding column positioning device includes a positioning stop 1 and a top plate 2. The positioning stop 1 is installed on the concrete foundation below the sliding column 3, serving as a sliding limiting component for the sliding column 3. The top plate 2 is set on the sliding column 3. During the sliding process, the sliding column 3 hits the positioning stop 1, and due to the obstruction of the positioning stop 1, the sliding column 3 cannot move further forward.

[0036] To effectively block the sliding column 3, the top plate 2 may include a steel plate welded to the lower middle of the sidewalls on both sides of the sliding column 3 in the sliding direction, with the top plate 2 perpendicular to the sliding direction of the sliding column 3. The top plate 2 is positioned on the left and right sides of the lower end of the sliding column 3. Since the sliding column 3 moves on the slide rail 5, there is a gap between the sliding column 3 and the concrete foundation at the height of the slide rail 5. The top plate 2 precisely cooperates with the positioning stops 1 positioned on the concrete foundation below the left and right sides of the sliding column 3, stably completing the blocking. The thickness and strength of the steel plate should be sufficient to stably press against the positioning stops 1.

[0037] For accurate positioning, the positioning stop 1 includes a baffle 11 installed on the concrete foundation below the slide rail 5 of the sliding column 3. The baffle 11 is located on the side of the sliding column 3 at the position to be positioned, and the baffle 11 is perpendicular to the sliding direction of the sliding column 3. The baffle 11 is located on the left / right side outside the bottom area of ​​the sliding column 3. The lower part of the baffle 11 is fixed to the concrete foundation, and the baffle 11 extends upward from the gap between the sliding column 3 and the concrete foundation to the height of the top plate 2, so as to stably fit and block the top plate 2.

[0038] The position of the baffle 11 should be set strictly according to the construction situation and the actual position. When the top plate 2 is on the baffle 11, the sliding column 3 slides into place and the position is accurate.

[0039] In a specific embodiment of this utility model, in order to ensure the stable installation of the baffle 11, the positioning baffle 1 further includes a rectangular fixing plate 12, on which a fixing hole 13 is provided, and a pad 14 is vertically connected to the lower end of the baffle 11, on which a connecting hole 15 is provided. The pad 14 and the fixing plate 12 are connected by bolts passing through the connecting hole 15 and the fixing hole 13. The fixing plate 12 is installed on the concrete foundation along the sliding direction.

[0040] The pad 14 at the lower end of the baffle 11 is connected to the fixing plate 12 by bolts and nuts. The fixing plate 12 is installed on the concrete foundation. The fixing plate 12 and the pad 14 are located between the sliding column 3 and the concrete foundation. The baffle 11 is perpendicular to the sliding direction. The baffle 11 can be installed stably, firmly and conveniently. The thickness and strength of the baffle 11 should be able to stably withstand the jacking of the top plate 2.

[0041] In one specific embodiment of this utility model, to further secure the baffle 11, a stiffening plate 16 is connected between the baffle 11 and the pad 14 on the side of the baffle 11 facing away from the top plate 2. During long-term use, the baffle 11 will not deform or tilt, and the stiffening plate 16 can prevent the baffle 11 from deforming.

[0042] In one specific embodiment of this utility model, for the stability of the baffle 11, the fixing hole 13 includes two circular holes arranged along the width direction of the fixing plate 12, and the connecting hole 15 includes two through holes on the pad 14 corresponding to the two circular holes. The pad 14 and the fixing plate 12 are fixed by the two pairs of circular holes, which are stable and firm, ensuring that the position of the baffle 11 is stable and will not be misaligned when pushed.

[0043] In one specific embodiment of this utility model, in order to ensure the baffle 11 is securely and conveniently installed, the fixing plate 12 can be installed on the existing anchor bolts 4 at the position to be positioned on the concrete foundation. Through holes 17 are provided at the center of both ends of the fixing plate 12. The distance between the two through holes 17 is equal to the spacing between the two anchor bolts 4 at the position to be positioned on the concrete foundation. The two through holes 17 are respectively inserted into the two anchor bolts 4 and fixed with nuts.

[0044] Two through holes 17 are made according to the spacing between the two anchor bolts 4 to facilitate the installation of the fixing plate 12. Two round holes are made according to the positioning position to ensure that the baffle 11 is accurately positioned after the pad 14 is installed on the fixing plate 12. The fixing plate 12 can be located between the sliding column 3 and the concrete foundation. After the anchor bolts 4 are inserted into the through holes 17, nuts can be tightened on both sides of the through holes 17 to fix the fixing plate 12 to the anchor bolts 4. The baffle 11 blocks the sliding top plate 2 above the fixing plate 12, thereby blocking the sliding column 3.

[0045] In one specific embodiment of this utility model, for ease of installation, the through hole 17 is an elongated hole, which is set along the centerline of the fixing plate 12. The elongated holes at both ends of the fixing plate 12 facilitate flexible installation of the fixing plate 12 and also facilitate more precise adjustment of the position of the baffle 11, keeping the fixing plate 12 horizontal.

[0046] In one specific embodiment of this utility model, in order to stably block the top plate 2, the baffle 11 is rectangular, with a height greater than the height of the top plate 2 and a width greater than the width of the top plate 2. The area of ​​the baffle 11 is greater than the area of ​​the top plate 2, which can completely block the top plate 2, providing stable and effective blocking.

[0047] There are many types of sliding components, but they generally have a supporting column at the bottom. In a specific embodiment of this utility model, the sliding column 3 can be the column at the lower end of the sliding component, and the top plate 2 is set at the lower edge of the column at the lower end of the sliding component to block it at the bottom of the entire sliding component.

[0048] If the sliding column 3 does not have its own plates on the left and right sides, top plates 2 can be welded to the left and right sides of the sliding column 3. In a specific embodiment of this utility model, the left and right sides of the sliding column 3 have their own armhole plates, so the armhole plates can be used as top plates 2. The position of the baffle 11 is set according to the thickness of the armhole plates so that the sliding column 3 is accurately positioned.

[0049] In one specific embodiment of this utility model, the sliding column sliding positioning device is provided on both sides of the sliding column 3, which further ensures stable positioning. In another specific embodiment of this utility model, depending on the structure of the sliding component and the conditions of the construction site, sometimes the sliding column sliding positioning device can only be provided on one side of the sliding column 3, which can also ensure accurate positioning of the sliding component.

[0050] During the sliding process of the sliding column 3, as it approaches the positioning point, the sliding speed of the sliding column 3 is gradually reduced. By repeatedly measuring the distance between the baffle 11 and the top plate 2, until the distance is approximately 1mm-2mm and they are almost touching, the sliding column 3 is successfully positioned. The sliding column positioning device is then removed.

[0051] The sliding column sliding positioning device according to the present invention has been described above by way of example with reference to the accompanying drawings. However, those skilled in the art should understand that various modifications can be made to the sliding column sliding positioning device proposed in the present invention without departing from the scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the contents of the appended claims.
