Description

Technical Field

[0001] The present invention relates to the technical field of steel structure installation, and specifically relates to a high-precision positioning control device for steel structure beam-column joints. Background Art

[0002] Steel structures are widely used in the construction field due to their advantages such as high strength and fast construction. The positioning accuracy of the joints between columns and beams directly affects the structural safety, but traditional construction has significant drawbacks: Firstly, during high-altitude hoisting, the position of the beam needs to be repeatedly adjusted to align the bolt holes, and the operation depends on manual experience, which is time-consuming and vulnerable to wind load disturbance, resulting in high positioning errors; Secondly, the installation of auxiliary positioning components (such as temporary support frames) is cumbersome, the disassembly, installation, and transfer efficiency are low, and they lack self-adaptive capabilities and are difficult to compensate for dynamic deviations.

[0003] Although existing technologies have tried to improve (such as laser positioning or elastic buckles), there are still deficiencies: On the one hand, complex positioning devices require special tools for installation, occupying high-altitude operation space and increasing construction risks; On the other hand, most components cannot兼顾水平与垂直双向微调,横梁对接时需多次测量校正,尤其多根立柱间的水平对齐依赖人工观察,精度难以保障。

[0004] Therefore, there is an urgent need for a positioning device that combines rapid disassembly and assembly, self-adaptive adjustment, and high-precision control capabilities to simplify the operation process and improve the quality of joint installation.

[0005] In view of this, the present invention proposes a high-precision positioning control device for steel structure beam-column joints, which solves the above technical problems. Summary of the Invention

[0006] In order to solve the deficiencies of the existing technology, the present invention provides a positioning device that combines rapid disassembly and assembly, self-adaptive adjustment, and high-precision control capabilities to simplify the operation process and improve the quality of joint installation.

[0007] The technical solution adopted by the present invention to solve its technical problems is a high-precision positioning control device for steel structure beam-column joints, including a column and a beam. A connecting cylinder is fixedly sleeved outside the column, and the beam is fixedly connected to the connecting cylinder through a connecting plate. A number of hole grooves for fixation are provided on the connecting cylinder, column, beam, and connecting plate. In addition, a positioning component is also included.

[0008] On the other hand, the positioning component includes a "C"-shaped positioning frame. The positioning frame is sleeved on the side wall of the column below the connecting cylinder. A locking plate is movably installed at the open end of the positioning frame. A set of positioning rods are respectively installed on both sides of the positioning frame, and the movable ends of the positioning rods contact the bottom of the beam.

[0009] It should be noted that the part "多数组件无法兼顾水平与垂直双向微调,横梁对接时需多次测量校正,尤其多根立柱间的水平对齐依赖人工观察,精度难以保障。" in the original text seems to be incomplete in English expression. I have tried my best to translate according to the existing content. You can check and correct it if necessary.On the other hand, a "U"-shaped card slot for engaging the locking plate is provided at the opening end of the positioning frame. A locking screw is installed through the card slot in a threaded fit manner. A locking lever is fixedly installed at the end of the locking screw. Transverse slots and longitudinal slots for engaging with the locking screw are respectively provided at both ends of the locking plate.

[0010] On the other hand, an elastic pad for increasing the contact pressure is provided on one side of the locking plate facing the side wall of the column.

[0011] On the other hand, a marking light ring is installed at the central position of the locking plate, and a laser lamp is fixedly installed on the side of the positioning frame opposite to the locking plate.

[0012] On the other hand, the positioning rod has an "L" - shaped structure. The short rod end of the positioning rod is rotatably inserted into the side wall position of the positioning frame. A sleeve perpendicular to the axis direction is fixedly installed at the long rod end of the positioning rod. A lapping rod is coupled and installed in the sleeve, and the lapping rod contacts the bottom of the cross - beam.

[0013] On the other hand, a compression spring is connected between the lapping rod and the sleeve. A lapping lever is fixedly installed at one end of the lapping rod away from the cross - beam. Tooth grooves are provided at one end of the lapping rod facing the cross - beam, and the tooth grooves on the two lapping rods on both sides of the cross - beam are engaged with each other.

[0014] On the other hand, a side ring is rotatably installed at one end of the sleeve facing the cross - beam. The side ring contacts the bottom side wall of the cross - beam. The side ring is made of an elastic material, and rib strips for squeezing and contacting the inner wall of the side ring are provided at the side wall position of the lapping rod.

[0015] On the other hand, a support plate is fixedly installed in the middle of the positioning frame. The top of the support plate contacts the bottom surface of the connecting cylinder. A buckle rod is slidably installed in the middle of the positioning frame. The upper end of the buckle rod is clamped with the top of the connecting cylinder, and a tension spring is connected between the lower end of the buckle rod and the positioning frame.

[0016] On the other hand, a plurality of pin holes are axially provided on the positioning rod. A buckle claw is installed on the buckle rod in a rotational fit manner. A pin shaft for cooperating with the pin holes is provided at the end of the buckle claw.

[0017] The beneficial effects of the present invention:

[0018] Through the active centering system of the laser lamp and the marking light ring, the accurate calibration of the horizontal attitude of the cross - beam is realized; the interlocking of the tooth grooves of the positioning rod and the spring reset design automatically lock the height of the cross - beam, avoiding repeated manual adjustment and improving the vertical positioning efficiency.

[0019] The positioning frame adopts a "匚" - shaped clamping structure, which is配合锁止板的纵横双向卡槽及弹力垫压紧,可快速完成拆装;扣杆与连接筒的弹性互锁机制免除额外加固步骤,便于装置周转复用。 It should be noted that there is an unclear part in the original text for item which is "配合锁止板的纵横双向卡槽及弹力垫压紧" in Chinese. The translation is adjusted according to the context as best as possible. If there are specific requirements for this part, it may need to be further refined.

[0020] The overlapping rod integrates the side ring and rib elastic clamping mechanism to automatically compensate for the dimensional deviation of the bottom of the crossbeam; the compression spring inside the sleeve buffers the impact of hoisting, ensuring positioning stability in strong winds and reducing the risk of high-altitude operations.

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] An embodiment of the present invention provides a positioning device that combines quick disassembly and assembly, adaptive adjustment, and high-precision control capabilities to simplify the operation process and improve the installation quality of nodes.

[0034] As Figures 1 to 5 shown, a preferred embodiment of the present invention proposes a high-precision positioning control device for steel structure beam-column joints, including a column 1 and a cross beam 2. A connecting cylinder 3 is fixedly sleeved outside the column 1, and the cross beam 2 is fixedly connected to the connecting cylinder 3 through a connecting plate 4. A number of hole grooves for fixing are provided on the connecting cylinder 3, the column 1, the cross beam 2, and the connecting plate 4. In addition, a positioning component 5 is also included.

[0035] The positioning component 5 includes a "C"-shaped positioning frame 6. The positioning frame 6 is sleeved on the side wall of the column 1 below the connecting cylinder 3. A locking plate 7 is movably installed at the open end of the positioning frame 6. A set of positioning rods 8 are respectively installed on both sides of the positioning frame 6, and the movable ends of the positioning rods 8 contact the bottom of the cross beam 2.

[0036] When it is necessary to connect and fix the column 1 and the cross beam 2, first, the connecting cylinder 3 is sleeved at a predetermined height position on the side wall of the column 1. Subsequently, the hole grooves on the connecting cylinder 3 and the column 1 are made to correspond. Then, the connection and fixation between the connecting cylinder 3 and the column 1 are achieved by using bolts or welding. Then, the positioning component 5 is taken out, the positioning frame 6 is snapped onto the side wall of the column 1, and the position of the positioning frame 6 is fixed by the locking plate 7. By the extension of the positioning rods 8, guiding and positioning are provided for the installation process of the cross beam 2.

[0037] Further, as Figures 5 to 8 shown, a "U"-shaped card slot 61 for snapping the locking plate 7 is provided at the open end position of the positioning frame 6. A locking screw 62 is installed through the card slot 61 in a threaded fit manner. A locking lever 63 is fixedly installed at the end of the locking screw 62. Transverse grooves 71 and longitudinal grooves 72 that are engaged with the locking screw 62 are respectively provided at both ends of the locking plate 7.

[0038] During the locking process of the locking plate 7, first, its transverse groove 71 enters the card slot 61 at one end of the positioning frame 6 and is engaged with the locking screw 62. At this time, the locking plate 7 can rotate around the locking screw 62. During the rotation of the locking plate 7, the longitudinal groove 72 at the other end rotates into the card slot 61 at the other end of the positioning frame 6. Through the vertical and horizontal double-engagement setting and the directional blocking of the "U"-shaped card slot 61, multi-directional locking and positioning of the locking plate 7 are achieved, improving the connection stability between the positioning component 5 and the column 1. After the position of the locking plate 7 is fixed, the locking screw 62 is rotated by拨动 the locking lever 63, and secondary fixation of the locking plate 7 is achieved through the "U"-shaped card slot 61, further completing the locking of the height position of the positioning component 5.

[0039] Furthermore, such as Figure 5 and Figure 6 As shown, the locking plate 7 is provided with an elastic pad 73 on the side facing the side wall of the column 1 to increase the contact pressure and improve the fixing stability.

[0040] Furthermore, such as Figure 1 , Figure 5 and Figure 6 As shown, a light ring 74 is installed in the center of the locking plate 7, and a laser light 740 is fixedly installed on the side of the positioning frame 6 opposite to the locking plate 7.

[0041] During the assembly and connection of the crossbeams 2 between two adjacent columns 1, the light emitted by one set of laser lights 740 can illuminate the other set of marker rings 74. Construction workers can observe the number of rings marked by the light spot to ensure the horizontal stability of the crossbeams 2 after assembly, thereby improving the overall stability of the steel structure.

[0042] Furthermore, such as Figures 5 to 7 As shown, the positioning rod 8 has an "L" shaped structure. The short end of the positioning rod 8 is rotatably inserted into the side wall of the positioning frame 6. The long end of the positioning rod 8 is fixedly installed with a sleeve 81 perpendicular to the axis. An overlapping rod 82 is coupled and installed inside the sleeve 81. The overlapping rod 82 contacts the bottom of the crossbeam 2. A compression spring 83 is connected between the overlapping rod 82 and the sleeve 81. An overlapping lever 84 is fixedly installed at the end of the overlapping rod 82 away from the crossbeam 2. A toothed groove 85 is opened at the end of the overlapping rod 82 facing the crossbeam 2, and the toothed grooves 85 on the two overlapping rods 82 on both sides of the crossbeam 2 are engaged with each other.

[0043] The overlapping rod 82 can rotate and slide within the sleeve 81. When the crossbeam 2 approaches the connecting cylinder 3 during hoisting, the overlapping rod 82 is first pulled outward to facilitate the crossbeam 2 reaching the predetermined fixed position. Then, the pulling of the overlapping rod 82 is released. At this time, under the elastic reset action of the compression spring 83, the overlapping rod 82 extends and enters the bottom of the crossbeam 2. At this time, the two opposing overlapping rods 82 are engaged with each other under the action of the tooth groove 85 to form a complete shaft structure and provide stable support for the bottom of the crossbeam 2. At this time, the height position of the crossbeam 2 is determined under the bottom support, realizing the positioning function in the vertical direction.

[0044] Furthermore, such as Figure 7 As shown, a side ring 86 is rotatably installed on one end of the sleeve 81 facing the crossbeam 2. The side ring 86 is in contact with the bottom side wall of the crossbeam 2. The side ring 86 is made of elastic material, and a rib 821 is provided on the side wall of the overlapping rod 82 to press against the inner wall of the side ring 86.

[0045] The side ring 86 can centrally abut against the bottom two sides of the crossbeam 2. When the bottom of the crossbeam 2 contacts the overlapping rod 82, its side wall position is simultaneously abutted by the side ring 86, thereby achieving the horizontal positioning of the crossbeam 2.

[0046] Furthermore, such as Figure 5 , Figure 6 and Figure 8 As shown, a support plate 64 is fixedly installed in the middle of the positioning frame 6. The top of the support plate 64 is in contact with the bottom surface of the connecting cylinder 3. A latch rod 65 is slidably installed in the middle of the positioning frame 6. The upper end of the latch rod 65 is engaged with the top of the connecting cylinder 3. A tension spring 66 is connected between the lower end of the latch rod 65 and the positioning frame 6. Several pin holes are opened along its axial direction on the positioning rod 8. A latch claw 67 is installed on the latch rod 65 by rotational engagement. The end of the latch claw 67 is provided with a pin that engages with the pin hole.

[0047] During the locking process of the positioning frame 6, the top of the buckle 65 is fastened to the top surface of the connecting cylinder 3 under the elastic force of the tension spring 66, while the support plate 64 is fastened to the bottom surface of the connecting cylinder 3. This upper and lower clamping action achieves an interlocking mechanism for the connecting cylinder 3. Simultaneously, the bidirectional traction action ensures the horizontality of the positioning frame 6 during installation and positioning. The elastic clamping action also reduces the need for additional support from the operators. Furthermore, the buckle 65 is fastened downwards to the top of the connecting cylinder 3, and its downward movement space is limited. Firstly, the installation height of the latch 67 is also locked relative to the height of the connecting cylinder 3. By engaging the latch 67 with the pin holes at different positions, the inclination of the positioning rod 8 can be adjusted and locked, thereby achieving the adjustment of the height position of the overlapping rod 82. The gradient-shaped adjustment and locking mechanism is used to meet the height adjustment requirements of the crossbeam 2 during installation and positioning, and to provide stable support for it. After the overlapping rod 82 is locked at the predetermined height position, the overlapping rod 82 can be rotated by moving the overlapping lever 84, thereby realizing the transportation of the crossbeam 2. The crossbeam 2 is then precisely moved towards the connecting cylinder 3 at the predetermined height position in a direction perpendicular to the overlapping rod 82 until its end reaches the fixed working position. The positioning process can be adjusted according to the working habits of the construction personnel, which is simple, convenient and easy to observe. After the connecting cylinder 3, column 1, crossbeam 2 and connecting plate 4 are all fixed, the positioning component 5 can be quickly disassembled as a whole by removing the locking plate 7, which is convenient for transfer to the next installation position.
