Description

Technical Field

[0001] This invention relates to the field of construction technology for irregularly shaped multi-angle roof purlins, and in particular to a sliding rail type spatial purlin corner position linkage control device and construction method. Background Technology

[0002] With the continuous development of construction technology in my country, many large-scale public building projects have adopted various large-area irregular curved metal roofs in pursuit of structural aesthetics. In the construction of metal roofs, the installation of purlins for the decorative base layer is undoubtedly of paramount importance; even slight deviations can affect the final appearance of the roof. Therefore, the installation of roof purlins presents a challenge for construction workers.

[0003] For example, a Chinese patent (application number: CN201811653976.3) discloses a method and construction process for installing large-size purlins on a large-span irregular roof. A hoisting device is set up on a roof beam. During the installation and positioning of the roof purlins, the supporting members are first fixed to the main steel structure. Then, an angle steel is added to the supporting members, allowing the large-size purlins to be hoisted and placed between the angle steel members and the roof beam. This method and construction process for installing large-size purlins on a large-span irregular roof, while ensuring safety, allows for millimeter-level accuracy in keel installation and significantly increases installation speed, resulting in good economic benefits and practical value.

[0004] Current construction methods typically involve using cranes to lift the purlins to their approximate position, with at least three workers involved: two to assist in moving the purlins, and one to measure and confirm their accurate location before welding. However, positional deviations are unavoidable during the process, requiring the welded purlins to be cut and re-welded, resulting in significant losses of manpower and resources. Furthermore, for purlins made of special materials, welding is not feasible due to material requirements, further hindering construction progress.

[0005] Therefore, it is necessary to propose a sliding rail type space purlin corner position linkage control device and construction method to address the above problems. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this invention is to provide a sliding rail type space purlin angle position linkage control device and construction method to solve the above problems.

[0007] A sliding rail type space purlin corner position linkage control device includes a main purlin, a secondary purlin, and a control component, wherein the main purlin and the secondary purlin are connected by the control component.

[0008] Preferably, the main purlin is a hollow, slender cuboid shape, and two main slide rails are provided on opposite sides of the main purlin.

[0009] Preferably, the secondary purlin is a hollow, slender cuboid shape with both ends sealed, and two secondary slide rails are provided on opposite sides of the secondary purlin.

[0010] Preferably, both the main purlin and the secondary purlin are made of aluminum alloy.

[0011] Preferably, both the main slide rail and the secondary slide rail are U-shaped.

[0012] Preferably, the regulating component includes a fixing plate, a connecting shaft, and an adjusting nut assembly. The two fixing plates are connected by the connecting shaft. One fixing plate is connected to the main purlin and fixed by the adjusting nut assembly, and the other fixing plate is connected to the secondary purlin and fixed by the adjusting nut assembly.

[0013] Preferably, the fixing plate has four holes symmetrically arranged on it.

[0014] Preferably, the adjusting nut assembly includes a long screw, two hexagonal nuts, and two washers. The long screw passes through the hole and extends into the main slide rail and the secondary slide rail. The two ends of the long screw 331 are respectively fitted with hexagonal nuts and washers.

[0015] A construction method for a sliding rail type space purlin angle position linkage control device, the method steps are as follows: S1: Connect one end of the secondary purlin to a main purlin. Fit washers and hexagonal nuts onto one end of two long screws, and place the long screw ends in one secondary slide rail. Fit washers and hexagonal nuts onto one end of two other long screws, and place the long screw ends in another secondary slide rail to seal one end of the secondary purlin. S2: Pass the four long screws mentioned in S1 through the four holes on a fixing plate, and put the washer and hexagonal nut on the other end of the four long screws. S3: Fit washers and hexagonal nuts onto one end of two long screws, and place the long screw end in one main slide rail. Fit washers and hexagonal nuts onto one end of two other long screws, and place the long screw end in another main slide rail. S4: Pass the four long screws mentioned in S3 through the four holes on another fixing plate, and put the washer and hexagonal nut on the other end of the four long screws; S5: Repeat steps S1 to S4 to connect the other end of the secondary purlin to another main purlin.

[0016] S6: Tighten the washer and hexagonal nut at the end of the fixing plate to push the main purlin and secondary purlin and adjust the connection position and angle between them.

[0017] Compared with existing technologies, the present invention offers the following advantages: The main purlin adopts a hollow, slender cuboid shape, which reduces weight and saves materials while ensuring structural strength. Its two main slide rails provide a stable connection and sliding track for the control component, ensuring smooth and precise control. The secondary purlin is designed as a hollow, slender cuboid with both ends sealed, reducing weight and saving materials while preventing the control component from slipping, thus enhancing overall stability. Its two secondary slide rails cooperate with the main slide rails to provide reliable sliding support for the control component, ensuring smooth corner adjustment. The control component connects two fixed plates via a connecting shaft, allowing them to rotate around the shaft. Combined with the adjusting nut assembly, this achieves the connection between the main and secondary purlins, flexible corner adjustment, and secure fixation. The operation is simple and the connection is reliable. The three components work together to achieve coordinated control of the corner positions of the main and secondary purlins, breaking the fixed connection mode and allowing flexible adjustment according to space requirements, significantly improving the adaptability and practicality of the device in different scenarios.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0024] like Figure 1 and combined Figures 2 to 9 As shown, a sliding rail type space purlin corner position linkage control device includes a main purlin 1, a secondary purlin 2 and a control component 3, wherein the main purlin 1 and the secondary purlin 2 are connected by the control component 3.

[0025] Furthermore, the main purlin 1 is a hollow, slender cuboid shape, and two main slide rails 11 are provided on opposite sides of the main purlin 1.

[0026] The benefits of adopting further technical solutions are as follows: the main purlin 1 adopts a hollow and slender cuboid shape, which reduces its own weight while ensuring structural strength and saving material costs; while the two main slide rails 11 provided on opposite sides provide a stable track for the connection and relative sliding of the control component 3 and the main purlin 1, ensuring the smoothness and accuracy of the control process.

[0027] Furthermore, the secondary purlin 2 is a hollow, slender cuboid shape with both ends sealed, and the secondary purlin 2 is provided with two secondary slide rails 21 on opposite sides.

[0028] The following benefits are derived from the adoption of a further technical solution: The secondary purlin 2 is designed as a hollow, slender cuboid with both ends sealed, which reduces weight and saves materials, prevents the control component 3 from slipping off, and enhances the overall structural stability of the secondary purlin 2 by sealing both ends; The two secondary slide rails 21 on opposite sides cooperate with the main slide rail 11 to provide a reliable track for the connection and sliding of the control component 3 and the secondary purlin 2, ensuring the smooth operation of the corner position control.

[0029] Furthermore, both the main purlin 1 and the secondary purlin 2 are made of aluminum alloy.

[0030] The benefits of adopting further technical solutions are as follows: Aluminum alloys have advantages such as light weight, high strength, corrosion resistance, and oxidation resistance, which not only make the main purlin 1 and secondary purlin 2 have a long service life and can adapt to a variety of complex environments, but also facilitate transportation and installation, thereby reducing the overall maintenance cost of the device.

[0031] Furthermore, both the main slide rail 11 and the secondary slide rail 21 are U-shaped.

[0032] The benefits of adopting a further technical solution are as follows: the concave structure can play a good role in limiting and guiding the connecting parts of the control component 3, preventing the connecting parts from leaving the track during the sliding process, ensuring the stability of the cooperation between the control component 3 and the main slide rail 11 and the secondary slide rail 21, and thus ensuring the accuracy of the angular position control.

[0033] Furthermore, the regulating component 3 includes a fixing plate 31, a connecting shaft 32, and an adjusting nut assembly 33. The two fixing plates 31 are connected by the connecting shaft 32. One fixing plate 31 is connected to the main purlin 1 and fixed by the adjusting nut assembly 33, while the other fixing plate 31 is connected to the secondary purlin 2 and fixed by the adjusting nut assembly 33.

[0034] The following are the benefits of adopting a further technical solution: The two fixing plates 31 of the adjusting component 3 are connected by a connecting shaft 32, so that the two fixing plates 31 can rotate around the connecting shaft 32, providing a basis for angular adjustment; one fixing plate 31 is connected to the main purlin 1 and fixed by the adjusting nut group 33, and the other is connected to and fixed to the secondary purlin 2. This structural design realizes the flexible adjustment and fixation of the angular position between the main purlin 1 and the secondary purlin 2, which is simple and convenient to operate and has a firm and reliable connection.

[0035] Furthermore, four holes 34 are symmetrically arranged on the fixing piece 31.

[0036] The benefits of adopting further technical solutions are as follows: the symmetrical layout of the holes 34 makes the connection between the fixing plate 31 and the main purlin 1 and the secondary purlin 2 more balanced and stable, avoiding loosening or damage to the connection due to uneven force. At the same time, the multiple holes 34 provide more options for the installation position of the adjusting nut assembly 33, enhancing the flexibility of adjustment.

[0037] Furthermore, the adjusting nut assembly 33 includes a long screw 331, two hexagonal nuts 332 and two washers 333. The long screw 331 passes through the hole 34 and extends into the main slide rail 11 and the secondary slide rail 21. The two ends of the long screw 331 are respectively fitted with hexagonal nuts 332 and washers 333.

[0038] The following benefits are derived from the adoption of a further technical solution: The long screw 331 of the adjusting nut assembly 33 passes through the hole 34 and extends into the main slide rail 11 and the secondary slide rail 21. The hexagonal nuts 332 and washers 333 at both ends can firmly fix the fixing plate 31 to the main purlin 1 and the secondary purlin 2. The position of the fixing plate 31 can be easily adjusted by tightening or loosening the hexagonal nuts 332, thereby achieving angular control. The washers 333 increase the force-bearing area, preventing damage to the fixing plate 31 when the nuts are tightened, and ensuring the stability and service life of the connection.

[0039] A construction method for a sliding rail type space purlin angle position linkage control device, the method steps are as follows: S1: Connect one end of the secondary purlin 2 to a main purlin 1. Fit one end of two long screws 331 with washers 333 and hexagonal nuts 332, and place this end of the long screws 331 in a secondary slide rail 21. Fit one end of the other two long screws 331 with washers 333 and hexagonal nuts 332, and place this end of the long screws 331 in another secondary slide rail 21 to block one end of the secondary purlin 2. S2: Pass the four long screws 331 mentioned in S1 through the four holes 34 on a fixing plate 31, and put the washer 333 and the hexagonal nut 332 on the other end of the four long screws 331. S3: Fit one end of the two long screws 331 with a washer 333 and a hexagonal nut 332, and place the long screw 331 end in one main slide rail 11. Fit one end of the other two long screws 331 with a washer 333 and a hexagonal nut 332, and place the long screw 331 end in another main slide rail 11. S4: Pass the four long screws 331 mentioned in S3 through the four holes 34 on another fixing plate 31, and put the washer 333 and the hexagonal nut 332 on the other end of the four long screws 331. S5: Repeat steps S1 to S4 to connect the other end of the secondary purlin 2 to another main purlin 1.

[0040] S6: The washer 333 and hexagonal nut 332 at the end of the tensioning and fixing plate 31 can push the main purlin 1 and the secondary purlin 2 and adjust the connection position and angle between them.

[0041] Compared with the prior art, the present invention has the following advantages: The main purlin 1 adopts a hollow and slender cuboid shape, which reduces weight and saves materials while ensuring structural strength. The main slide rails 11 on both sides provide a stable connection and sliding track for the control component 3, ensuring smooth and precise control. The secondary purlin 2 is designed as a hollow and slender cuboid with both ends sealed, which reduces weight, saves materials, and prevents the control component 3 from slipping, enhancing overall stability. The secondary slide rails 21 on both sides cooperate with the main slide rails 11 to provide reliable sliding support for the control component 3, ensuring smooth corner adjustment. The control component 3 is connected to two fixed plates 31 through a connecting shaft 32, allowing them to rotate around the shaft. Combined with the adjusting nut group 33, the connection, flexible corner adjustment, and firm fixation of the main purlin 1 and the secondary purlin 2 are realized. The operation is simple and the connection is reliable. The three components work together to realize the linkage control of the corner positions of the main purlin 1 and the secondary purlin 2, breaking the fixed connection mode and allowing flexible adjustment according to space requirements, greatly improving the adaptability and practicality of the device in different scenarios.

[0042] Working principle: The main purlin 1 and the secondary purlin 2 are connected and their angle positions are linked through the adjusting component 3. The main slide rail 11 of the main purlin 1 and the secondary slide rail 21 of the secondary purlin 2 provide the track foundation for adjustment. The two fixed plates 31 of the adjusting component 3 can rotate relative to each other through the connecting shaft 32, providing a movable joint for angle adjustment. The fixed plates 31 are fixed through holes 34, through which the long screws 331 of the adjusting nut group 33 pass and extend into the main slide rail 11 and the secondary slide rail 21. The hexagonal nuts 332 and washers 333 at both ends are used to fix and adjust the tightness, thereby driving the main purlin 1 and the secondary purlin 2 to slide along the slide rail and adjust their relative angle positions, ultimately achieving flexible angle position linkage control.

[0043] Example 1: Installation Project of Hyperbolic Curved Metal Roof Purlins for a Large Gymnasium The sports center gymnasium in a provincial capital city has a large-span hyperbolic curved metal roof (maximum span 48m, arc height 6.5m), requiring the installation of aluminum alloy purlins as the base layer for the roof decoration. Traditional construction methods employ "lifting machinery hoisting + manual pushing and positioning + welding fixation." Because the hyperbolic curve requires continuous fine-tuning of the angle, deviations of ±5mm or more often occur after welding, necessitating cutting and re-welding. This results in a material loss rate exceeding 15%, and the aluminum alloy material is prone to deformation during welding, hindering construction progress.

[0044] Based on engineering load and arc-shaped requirements, the parameters of the core components of the device are designed as follows: Main purlins are made of aluminum alloy (6061-T6), with a hollow rectangular structure, measuring 400mm×200mm×8mm (length×width×wall thickness), and a single purlin is 6m long. Secondary purlins are made of aluminum alloy (6061-T6), with a hollow rectangular structure (both ends sealed), measuring 300mm×150mm×6mm, and a single length of 4m. Main / secondary slide rails, U-shaped structure, opening width 20mm, depth 15mm, integrally formed with purlins (factory prefabricated). Adjustment components, fixing plate: stainless steel (304), size 180mm×120mm×5mm, 4 symmetrical holes (hole diameter 12mm); connecting shaft: stainless steel shaft with diameter 16mm and length 130mm; Adjusting nut assembly: M12 long screw (100mm in length) + hexagonal nut (M12) + washer (20mm in diameter, 3mm in thickness).

[0045] Angle adjustment: Due to the changes in the hyperbolic curved surface, the angle between the main purlin and the secondary purlin needs to be continuously adjustable within the range of 85°~115° to ensure that the purlin fits the roof's curved design as a whole. Position adjustment: The lateral sliding accuracy of the secondary purlin along the main purlin slide rail needs to reach ±2mm to avoid misalignment at the arc joint; Fixed requirement: After adjustment, it must withstand the load of the roof finishing layer (metal panel + insulation layer) (approximately 0.8 kN / m). 2 It is also resistant to outdoor wind and rain corrosion over a long period of time.

[0046] Implementation steps: Pre-installation of main purlins: According to the roof arc design drawings, the main purlins are laid on the main steel structure at 3m intervals and fixed with temporary supports (without welding). The arc trajectory of the main purlins is calibrated by a total station, and the error is controlled within ±3mm.

[0047] Secondary purlin connection (corresponding to S1-S4): Place one end of two M12 long screws with a washer and a hexagonal nut, and insert them into the concave slide rail on one side of the secondary purlin (opening inward). Similarly, place the other two long screws into the slide rail on the other side to seal the end of the secondary purlin. Pass four long screws through the four holes of a fixing plate, and place a washer and nut on the other end (do not tighten yet). Then, in the same way, connect the other fixing plate to the main purlin slide rail through long screws (the long screws extend into the main purlin slide rail).

[0048] Fine-tuning of angle and position: Loosen the hexagonal nuts at both ends of the fixing plate, push the secondary purlin to slide laterally along the main purlin slide rail (adjust the arc connection position), and at the same time rotate the secondary purlin around the connecting shaft of the control component (adjust the included angle between the main and secondary purlins). Use a laser line projector to monitor the arc trajectory of the secondary purlin in real time until the deviation is ≤2mm.

[0049] Fix the other end of the secondary purlin (corresponding to S5): Repeat steps 2-3 to connect the other end of the secondary purlin to the adjacent main purlin, ensuring that the secondary purlin fits snugly against the roof's curve.

[0050] Final fixing (corresponding to S6): Tighten all adjusting nut groups with a torque wrench (torque value 35 N・m) to ensure that the fixing plate and purlin are in close contact and that the long screws inside the slide rail are not loose.

[0051] Implementation results: The purlin installation accuracy reached ±2mm, meeting the design requirements of the hyperbolic curved roof, with no need for cutting and re-welding due to deviation; compared with traditional construction, it reduced the number of auxiliary workers by 2 per group, and shortened the construction cycle of a single-span roof by 30%; aluminum alloy purlins do not require welding, avoiding material deformation, and are resistant to outdoor corrosion, thus extending their service life.

[0052] Example 2: Installation Project of Multi-Angle Folded Roof Purlins for a Modern Art Exhibition Hall The roof of a modern art exhibition hall features a three-fold irregular structure (the three folds correspond to the east, south, and north exhibition areas respectively), with designed angles between the folds of 120° (east-south fold), 135° (south-north fold), and 150° (north-east fold). The roof purlins need to be fixed at multiple angles, and the client requires a "welding-free" process (to avoid welding marks affecting the building's aesthetics). Traditional construction methods cannot meet the requirements for precise fixing at multiple angles.

[0053] Considering the characteristics of folded roofs—"multi-angle fixing" and "relatively small load"—the device parameters are designed as follows: Main purlins are made of aluminum alloy (6063-T5), with a hollow rectangular structure, dimensions of 350mm×180mm×7mm, and a single length of 5m. Secondary purlins, made of aluminum alloy (6063-T5), hollow rectangular structure (sealed at both ends), dimensions 280mm×140mm×5mm, single length 3.5m. Main / secondary slide rails, U-shaped structure, opening width 18mm, depth 12mm, integrally formed with purlins. Adjustment components, fixing plate: stainless steel (304), size 150mm×100mm×4mm, 4 symmetrical holes (hole diameter 10mm); connecting shaft: stainless steel shaft with diameter 14mm and length 110mm; Adjusting nut assembly: M10 long screw (80mm in length) + hexagonal nut (M10) + washer (18mm in diameter, 2.5mm in thickness).

[0054] Angle adjustment: Three specific angles (120°, 135°, 150°) need to be precisely fixed, with an angle error ≤0.5°; Position adjustment: The secondary purlins need to be aligned with the intersection line of the folded surfaces along the slide rail of the main purlins, with a lateral positioning accuracy of ±1.5mm; Aesthetic requirements: The control mechanism must be hidden inside the purlin to avoid affecting the roof decoration effect.

[0055] Implementation steps: Folding angle pre-fabrication: In the ground processing area, according to the design angle (120°, 135°, 150°), the two fixed plates of the adjustment mechanism are pre-adjusted to the target angle through the connecting shaft. After calibration with an angle gauge, the nut is temporarily tightened to fix the angle (to avoid displacement during transportation).

[0056] Main purlin fixing: Fix the main purlins to the main steel structure according to the folded sections (the main purlins of the east, south and north exhibition areas are parallel to the exhibition area walls respectively), and use a level to calibrate the levelness of the main purlins, with an error ≤1mm / m.

[0057] Secondary purlins are connected to main purlins (corresponding to S1-S5): In the pre-adjustment angle control mechanism, one fixing plate is connected to the main purlin slide rail via the adjusting nut group (the long screw extends into the concave slide rail of the main purlin, with the opening facing inward and hidden); the other fixing plate is connected to the secondary purlin slide rail. Loosen the temporary nut and push the secondary purlin to slide along the slide rail so that the edge of the secondary purlin is aligned with the fold line (calibrated with an ink line).

[0058] Angle verification and fixing (corresponding to S6): Use a digital angle gauge to verify the included angle between the main and secondary purlins (ensure the error of 120° / 135° / 150° is ≤0.5°), and at the same time use a vernier caliper to check the positioning deviation of the secondary purlins (≤1.5mm). After confirming that there are no errors, use a torque wrench (torque value 25N・m) to tighten all adjusting nut groups to complete the fixing.

[0059] Concealed design: The fixing plate and connecting shaft of the control mechanism are located inside the purlin (with the slide rail opening facing inward), and are completely covered when the roof metal panels are laid later, with no exposed parts.

[0060] Implementation results: The fixed error of the included angle of the three sets of folded surfaces is ≤0.3°, the folded surfaces are connected smoothly, and the requirements of architectural aesthetics are met; there is no welding operation throughout the process, avoiding welding marks, and the aluminum alloy purlin structure is intact and without deformation; if the folded surface angle needs to be adjusted later (such as roof renovation), it can be readjusted simply by loosening the adjusting nut set, without replacing parts, saving 60% of maintenance costs.
