Description

Technical Field

[0001] This invention relates to the field of building construction, and in particular to an intelligent installation auxiliary system for bolted installation of eaves structures. Background Technology

[0002] The eaves refer to the horizontal, protruding section at the top of a building's facade, typically depicted as a central feature. The roof eaves specifically refer to the upper edge of the eaves at the outermost edge of a large roof, also known as the "upper edge." Their function is to facilitate the drainage of rainwater from the roof and protect the walls. They are also a key decorative element of a building, commonly taking the form of projecting eaves or cladding eaves.

[0003] In steel structure buildings, due to the deformation caused by the weight of the steel components, the actual installation effect of the eaves often deviates from the target design effect. Especially with longer lengths, the eaves ends will sag due to their own weight and overall length. In this case, the overall structure cannot be simply understood as a connection between straight lines and points, but rather as a connection between curves and spheres. Furthermore, since the structure extensively uses bolted connections, the effectiveness of threaded fastening is greatly affected by the precision of the thread fit, causing the installed ball joints and rods to easily become eccentric and deformed, deviating from the designed target structure. At the same time, the high-altitude nature of eaves work further increases the difficulty of structural adjustments.

[0004] To solve the above problems, an intelligent installation auxiliary system for bolted installation of eaves structures is needed. Summary of the Invention

[0005] This invention addresses the problem in existing steel structure buildings where the actual installation effect of the eaves often deviates from the target design due to the deformation caused by the weight of the steel components. This is especially true for longer structures where the eaves ends sag due to weight and overall length. In such cases, the eaves frame cannot be simply understood as a connection between straight lines and points, but rather as a connection between curves and spheres. Furthermore, the extensive use of bolted connections in the structure means that the threaded fastening effect is greatly affected by the thread fit accuracy, making it easy for the installed ball joints and rods to become eccentric and deformed, deviating from the designed target structure. Additionally, the high-altitude nature of eaves installation further increases the difficulty of structural adjustments. This invention provides an intelligent installation assistance system for bolted installation of large eaves structures, employing target position decomposition to solve the aforementioned problems.

[0006] This invention provides an intelligent installation auxiliary system for bolted installation of eaves structures, including several pole perimeter position sensors, several ball joint positioning sensors, a ball center positioning module, a pole axis fitting module, a steel structure cantilever support fitting module, and a vertical lifting frame.

[0007] At least three pole circumference position sensors are installed on both ends and the middle of the connecting poles of the space frame in the same radial direction. The pole circumference position sensors on the same connecting poles have the same pole information identification. Ball joint positioning sensors are installed on the outer surface of the connecting ball joints. At least four ball joint positioning sensors are installed on each connecting ball joint. The ball joint positioning sensors on the same connecting ball joints have the same ball joint information identification. The ball center positioning module is connected to the signal of each ball joint positioning sensor. The pole axis fitting module is connected to the signal of each pole circumference position sensor. The steel structure cantilever support fitting module is connected to the data of the ball center positioning module and the pole axis fitting module. The vertical lifting frame is used to vertically fix and lift the frame after initial assembly and the adjusted steel structure cantilever support.

[0008] The method of using the intelligent installation auxiliary system for bolted installation of a large eaves structure according to the present invention, as a preferred embodiment, includes the following steps:

[0009] S1. Install the position sensor on the steel structure cantilever support assembly and import the target model of the steel structure cantilever support into the steel structure cantilever support fitting module.

[0010] S2. Fit the actual ball center position tolerance range based on the ball center position of each connecting ball joint in the target model of the steel structure cantilever support, and determine the slope and position tolerance range of each connecting rod based on the position of each connecting rod in the target model of the steel structure cantilever support.

[0011] S3. Assemble the actual steel structure cantilever support according to the target model;

[0012] S4. The vertical lifting frame is lowered to its lowest position, and the steel structure cantilever support is installed at the vertical movable end. The vertical lifting frame then lifts the steel structure cantilever support to be completely off the ground.

[0013] S5. The ball center positioning module collects the ball joint positioning sensor signal and then fits the actual ball center position of each connecting ball joint. The rod axis fitting module collects the rod circumference position sensor signal and then fits the actual position and slope of each connecting rod.

[0014] S6. The ball center positioning module and the rod axis fitting module respectively transmit the ball center position information and the rod position information to the steel structure cantilever support fitting module to check whether each structure is within the position tolerance range. If yes, proceed to step S8; otherwise, proceed to step S7.

[0015] S7. Lower the vertical lifting frame, adjust the fastening relationship between the connecting rod and the connecting ball joint that are not within the tolerance range, and then proceed to step S4.

[0016] S8. Install and bolt the cantilever support of the hoisted steel structure.

[0017] The method of using the intelligent installation auxiliary system for bolted installation of a large eaves structure according to the present invention, as a preferred method, is as follows: the actual sphere center position tolerance range in step S2 is: in the target model, a spatial orthogonal coordinate system is created, the xyz axis positions of each sphere center in the orthogonal spatial coordinate system are selected, and the system is scaled proportionally to the tolerance range sphere. The point of the tolerance range sphere closest to the installation end of the steel structure cantilever support is the target model sphere center. The target model is scaled proportionally to fill the tolerance range sphere to the maximum extent. The tolerance range of the current sphere center is the part that coincides with the cube range orthogonally decomposed by the line connecting the current sphere center in the tolerance range sphere and the target model sphere center.

[0018] The slope tolerance and position range of the connecting rod in step S2 are as follows: the position tolerance range is determined by the center of the ball connected to the current connecting rod, and the slope tolerance range is the absolute value of the difference between the slope of the line connecting the center tolerance range and the slope of the ideal position.

[0019] The intelligent installation auxiliary system for bolted installation of eaves structure according to the present invention, as a preferred method, is as follows: the ball center positioning module in step S5 collects the ball joint positioning sensor signals and fits the actual ball center position of each connected ball joint as follows: select ball joint positioning sensor signals with the same ball joint information identifier, fit three position signals into a spatial plane, draw a perpendicular line from the center of the spatial plane, traverse all points in the space, and select the point with the shortest distance to each perpendicular line as the ball center;

[0020] The method for fitting the actual position and slope of each connecting rod after collecting the signals from the rod circumference position sensor in step S5 is as follows: Select rod circumference position sensors with the same rod information identifier, and obtain the axis positions of the two ends and the middle rod by determining the position of the center of the circle in space according to the relationship between at least three points and the center of the circle based on the three sets of rod circumference position sensors at both ends and the middle rod. Connect the three axis points in sequence to form a broken line at both ends, make a regression curve based on the shape of the broken line, and select the middle axis position as the tangent of the regression curve. Translate the tangent of the regression curve in the direction parallel to the line connecting the two ends of the axis until the midpoint of the regression curve coincides with the midpoint of the line connecting the two ends of the axis, which is taken as the spatial position and slope of the rod as a whole.

[0021] The present invention discloses an intelligent installation auxiliary system for bolted installation of a large eaves structure. In a preferred embodiment, the vertical lifting frame includes a fixed frame and a sliding frame. The fixed frame is fixed to the ground and is provided with a vertical slide rail. The sliding frame is movably mounted on the slide rail of the fixed frame and is provided with a vertical panel for connecting the fixed end of the steel structure cantilever support.

[0022] In the intelligent installation auxiliary system for bolted installation of the eaves structure described in this invention, as a preferred embodiment, at least one of the ball joint positioning sensors on each connecting ball joint has a different maximum diameter than the other ball joint positioning sensors.

[0023] The intelligent installation auxiliary system for bolted installation of the eaves structure described in this invention, as a preferred embodiment, involves the installation of the pole circumference position sensors on the connecting rod in the following manner: at least three pole circumference position sensors are grouped together and bound to the outer circumference of the connecting rod using flexible installation straps.

[0024] The beneficial effects of this invention are as follows:

[0025] This system decomposes the target location within a limited range, placing the structural nodes of the overall structure in a relatively ideal position. It fully considers the strength characteristics of the metal structure, making the final eaves installation structure closer to the ideal state. It avoids the structural changes caused by the weight of the metal itself, and makes reasonable fine-tuning of the overall structure, making the overall structure more stable and the overall eaves more controllable at high altitudes.
