Description

Technical Field

[0001] This invention belongs to the field of civil engineering technology, specifically relating to an arc-shaped template support device and method based on arc geometric parameterization. Background Technology

[0002] In modern architectural engineering, curved structures, due to their combined aesthetic value and spatial functional advantages, are widely used in building facades, domes, bridge load-bearing systems, and balcony beams in civil buildings. Traditional curved formwork erection techniques, such as loose-fitting wooden formwork and standardized formwork, have insurmountable technical shortcomings: the former requires on-site cutting and splicing of numerous wooden components, resulting in cumbersome manual operations, low construction efficiency, and the inherent elastic deformation characteristics of wood easily leading to deviations in beam cross-sectional dimensions and surface flatness defects; the latter, while improving some construction accuracy through prefabricated steel formwork, has fixed formwork curvature parameters, requiring custom-made molds for different curvatures. When the radius of curvature of the target curved structure exceeds the set value, a straight-line substitution method can be used to erect the curved formwork, but the construction error must be strictly controlled within the acceptable tolerance range for architectural engineering. Therefore, a curved formwork erection device and method based on arc geometry parameterization should be provided. Summary of the Invention

Detailed Implementation

[0024] like Figure 1 , Figure 2 and Figure 3As shown, the arc-shaped template support device of the present invention includes an arc-shaped template, a support mechanism and an auxiliary support mechanism connected to the arc-shaped template for supporting and adjusting the radius of curvature of the arc-shaped template, and an intelligent control device for controlling and calibrating the radius of curvature of the arc-shaped template. The arc-shaped template includes multiple standardized templates 1 connected sequentially by a hinge connection mechanism. The support mechanism includes a template support frame 2, multiple electric linear push rods 3 installed on the template support frame 2, and connecting frames installed at the ends of the electric linear push rods 3. The multiple electric linear push rods 3, the multiple connecting frames, and the multiple standardized templates 1 correspond one-to-one. The connecting frame includes a support plate 4-1, a first connecting rod 4-2 connected to the outer side of the support plate 4-1, and at least two second connecting rods 4-3 connected to the inner side of the support plate 4-1. The extended end of the electric linear push rod 3 is connected to the first connecting rod 4-2 by a ball joint 5. At least two of the second connecting rods 4-3 are connected to the outer side of the standardized template 1. The intelligent control device includes a controller, multiple electronic angle measuring instruments 9 and multiple laser rangefinders 10 connected to the input end of the controller, and the first drive motors of the multiple electric linear push rods 3 are all controlled by the controller.

[0025] In this embodiment, by connecting a support mechanism and an auxiliary support mechanism to the arc-shaped template, and setting an intelligent control device for controlling and calibrating the curvature radius of the arc-shaped template, the arc-shaped template includes multiple standardized templates 1 connected sequentially by a hinge connection mechanism. The support mechanism includes a support frame 2, multiple electric linear push rods 3, and a connecting frame. The multiple electric linear push rods 3, the multiple connecting frames, and the multiple standardized templates 1 correspond one-to-one. In actual use, under the support of the support mechanism, the arc-shaped template can be stably and vertically erected on the bottom template without tilting. Under the control of the intelligent control device, by adjusting the extension and retraction length of the multiple electric linear push rods 3, the splicing angle between any two adjacent standardized templates 1 can be adjusted, thereby achieving the purpose of adjusting the curvature radius of the arc-shaped template.

[0026] In this embodiment, the connecting frame includes a support plate 4-1, a first connecting rod 4-2, and at least two second connecting rods 4-3. In actual use, the connecting frame can bear and transmit the pushing force of the electric linear push rod 3, and can keep the shaped template 1 stable under the pushing force of the electric linear push rod 3. Since the extended end of the electric linear push rod 3 is connected to the first connecting rod 4-2 through a ball joint universal joint 5, under the hinge action of the ball joint universal joint 5, the connecting frame and the shaped template 1 can simultaneously deflect around the hinge connection mechanism while the electric linear push rod 3 is always perpendicular to the formwork frame 2. The connection is stable and reliable, and the rotation is flexible, resulting in good performance.

[0027] In this embodiment, the intelligent control device includes a controller, multiple electronic angle measuring instruments 9 and multiple laser rangefinders 10. In actual use, the electronic angle measuring instruments 9 can measure the splicing angle between two adjacent standardized templates 1 in real time and transmit the measurement data to the controller in real time. The laser rangefinders 10 can measure the length of the electric linear actuators 3 in real time and transmit the measurement data to the controller in real time. After comparison and calculation by the controller, the multiple electric linear actuators 3 of the support mechanism and the auxiliary support mechanism are precisely controlled.

[0028] In this embodiment, when using a straight-line substitution method for curved-line template erection, the construction error is... The precise definition can be achieved by using the sag between the standardized template 1 and the target circular arc curve, according to the formula. ,in, Let be the theoretical radius of the target circular arc. This is the theoretical vertical distance between the inner side of the formwork support 2 and the center surface of the arc-shaped template, wherein the center surface of the arc-shaped template is parallel to the inner side of the formwork support 2. The width of template 1 is used for standardization; when the theoretical radius of the target circular arc curve is... Much larger than the width of the standardized template 1 To simplify construction calculations and improve practical efficiency, the above error calculation formula can be optimized as follows: .

[0029] In this embodiment, if the width of the standardized template 1 is... The radius is 400mm. Considering the industry standard of 2mm for straight-line formwork in construction engineering, the theoretical radius of the target circular arc is calculated by reverse derivation using the optimized formula. =10m, that is, when the theoretical radius of the target circular arc curve is... For lengths >10m, curved formwork can be erected using a straight-line substitution method, which reduces construction error. It can be strictly controlled within the acceptable tolerance range for construction projects. If the width of the standardized template 1... If the theoretical radius of the target circular arc is 300mm, then... For heights greater than 5.7m, curved formwork can be erected using a straight-line substitution method, which reduces construction error. It can be strictly controlled within the acceptable tolerance range for construction projects.

[0030] like Figure 4As shown, in this embodiment, the hinge connection mechanism includes a hinge sleeve 1-1 disposed on one end face of the shaped template 1 and a hinge shaft disposed on the other end face of the shaped template 1. The hinge shaft includes a large-diameter shaft section 1-2-1 and a small-diameter shaft section 1-2-2 arranged coaxially. The diameter of the large-diameter shaft section 1-2-1 is equal to the outer diameter of the hinge sleeve 1-1, and the diameter of the small-diameter shaft section 1-2-2 is equal to the inner diameter of the hinge sleeve 1-1.

[0031] In actual assembly, it is only necessary to fit the hinge sleeves 1-1 of the two adjacent preforms 1 onto the small diameter shaft section 1-2-2 of the hinge shaft. Under the driving action of the support mechanism and the auxiliary support mechanism, the two adjacent preforms 1 can rotate around the hinge sleeves 1-1 and the hinge shaft.

[0032] like Figure 2 and Figure 3 As shown, in this embodiment, the auxiliary support mechanism includes a housing 8 installed at the top of the small diameter shaft section 1-2-2 and two cantilever support arms 6-1 mounted on the top of the small diameter shaft section 1-2-2. The housing 8 is provided with two sets of auxiliary drive mechanisms for driving the two support arms 6-1 to deflect. The grating of the electronic angle measuring instrument 9 is set on the contact surface of the connection end of the two support arms 6-1. A vertical connecting rod 6-2 is installed at the cantilever end of the support arm 6-1. An auxiliary push plate 6-3 is installed at the bottom end of the vertical connecting rod 6-2. Rectangular clearance grooves 8-1 are opened on the two sides of the housing 8.

[0033] In this embodiment, the auxiliary drive mechanism includes a second drive motor 7-1 fixed on the inner wall of the housing 8 and a bushing 7-2 fitted on the top of the small diameter shaft section 1-2-2 and fixedly connected to the connecting end of the support arm 6-1. The output shaft of the second drive motor 7-1 and the bushing 7-2 are connected by a gear assembly.

[0034] In actual use, the rectangular clearance groove 8-1 can provide sufficient clearance space for the deflection of the support arm 6-1, avoiding interference and collision between the support arm 6-1 and the housing 8.

[0035] In actual use, when using the auxiliary support mechanism to fine-tune the splicing angle between two adjacent standardized templates 1, the specific operation process is as follows: When it is necessary to reduce the splicing angle between two adjacent standardized templates 1, it is only necessary to use two auxiliary drive mechanisms to drive the two support arms 6-1 respectively, so that both support arms 6-1 deflect around the small diameter shaft segment 1-2-2 towards the inner side of the arc-shaped template. Under the joint push of the support arms 6-1, the vertical connecting rod 6-2, and the auxiliary push plate 6-3, the purpose of reducing the splicing angle between two adjacent standardized templates 1 can be achieved. At this time, the electronic angle... The measuring instrument 9 can measure the included angle between the two support arms 6-1 in real time, and the included angle between the two support arms 6-1 is the splicing angle between the two adjacent standardized templates 1. When it is necessary to increase the splicing angle between the two adjacent standardized templates 1, the first drive motor of the electric linear push rod 3 and the second drive motor 7-1 of the auxiliary support mechanism need to cooperate with each other so that the two support arms 6-1 deflect around the small diameter shaft segment 1-2-2 to the outer side of the arc template. Under the pulling action of the electric linear push rod 3, the purpose of increasing the splicing angle between the two adjacent standardized templates 1 is achieved.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the number of laser rangefinders 10 is equal to the number of electric linear actuators 3, and they correspond one-to-one. The laser rangefinders 10 are mounted on the base plate of the electric linear actuators 3.

[0037] like Figure 4 , Figure 5 , Figure 6 and Figure 7 The method shown is a method for supporting an arc template based on arc geometry parameterization. The method includes the following steps: Step 1: Theoretical calculation of arc-shaped formwork support parameters based on arc geometry parameters: The support parameters for the arc-shaped template include the theoretical length of the electric linear actuator 3 corresponding to each of the standardized templates 1. The angle between the axis of the electric linear actuator 3 and the normal direction of the plane of the standardized template 1 The splicing angle between the two adjacent standardized templates 1 ; Among them, the angle between the axis of the electric linear actuator 3 and the normal direction of the plane of the standardized template 1 The equation of the arc curve is determined using the following method: The slope of the tangent at the support point is . The slope of the line corresponding to the plane normal of the standardized template 1 is , According to the formula: Calculate each included angle ; Since the arc-shaped template has both concave and convex structural forms, therefore, When the arc-shaped template is a concave structure, according to the formula ,in, Let be the theoretical radius of the target circular arc. This is the theoretical vertical distance between the inner side of the formwork support 2 and the center surface of the arc-shaped template, wherein the center surface of the arc-shaped template is parallel to the inner side of the formwork support 2. To determine the width of the standardized template 1, calculate the theoretical length of any electric linear actuator 3. ; When the arc-shaped template has a convex structure, according to the formula Calculate the theoretical length of any electric linear actuator 3. ; Wherein, according to the formula Determine the splicing angle between two adjacent standardized templates 1. ; Step 2: Assemble and erect the arc-shaped template, with adjacent preformed templates 1 connected by a hinge mechanism; Step 3: Set up the support mechanism and auxiliary support mechanism; Step 301: Determine the number of formwork support frames 2 and erect the formwork support frames 2; Step 302: Install a connecting frame on the outer side of each of the standardized templates 1, install an electric linear push rod 3 on each connecting frame, and install the fixed end of the electric linear push rod 3 on the corresponding support frame 2, so that the axis of the electric linear push rod 3 is perpendicular to the support frame 2. Step 303: Install the auxiliary support mechanism at the top of the hinge axis of each hinge connection mechanism; Step 4: Deploy multiple electronic angle measuring instruments 9 and multiple laser rangefinders 10; Step 5: Use an intelligent control device to control and calibrate the radius of curvature of the arc-shaped template. The specific process includes: Step 501: Determine a reference template among the multiple standardized templates 1. First, adjust the actual length of the electric linear actuator 3 connected to the reference template so that the actual length of the electric linear actuator 3 on the reference template is... Equal to the theoretical length of the electric linear actuator 3 on the reference template Then, the reference template is fixed onto the bottom template. Step 502: Using the reference template as a reference, simultaneously adjust the actual length of the electric linear actuator 3 connected to the other prefabricated templates 1 and the actual splicing angle between any two adjacent prefabricated templates 1: The laser rangefinder 10 transmits the real-time measured data of the actual length of the electric linear push rod 3 to the controller. The electronic angle measuring instrument 9 transmits the real-time measured data of the actual splicing angle between any two adjacent standardized templates 1 to the controller. The controller calculates and compares the actual data with the theoretical data. By controlling the first drive motor to extend and retract the electric linear push rod 3, and the second drive motor 7-1 to drive the two support arms 6-1 to deflect, the support arms 6-1 drive the vertical connecting rod 6-2 and the auxiliary push plate 6-3 to push the two adjacent standardized templates 1, thereby adjusting the actual splicing angle between the two adjacent standardized templates 1.

[0038] like Figure 7 As shown, in actual use, when constructing a circular column formwork, the outer surface of the circular column is divided into four equal parts, that is, the number of formwork support 2 and the number of arc-shaped formwork are both four. The circular column formwork can be erected by using four arc-shaped formwork support devices in a straight-to-curved manner. It has a wide range of applications and is easy to promote and apply.

To determine the width of the standardized template (1), calculate the theoretical length of any electric linear actuator (3). ; When the arc-shaped template has a convex structure, according to the formula Calculate the theoretical length of any electric linear actuator (3). ; Wherein, according to the formula Determine the splicing angle between two adjacent standardized templates (1). ; Step 2: Assemble and erect the arc-shaped template, and connect two adjacent standardized templates (1) through a hinge connection mechanism; Step 3: Set up the support mechanism and auxiliary support mechanism; Step 301: Determine the number of formwork support frames (2) and erect the formwork support frames (2); Step 302: Install a connecting frame on the outer side of each of the standardized templates (1), install an electric linear push rod (3) on each connecting frame, and install the fixed end of the electric linear push rod (3) on the corresponding support frame (2) so that the axis of the electric linear push rod (3) is perpendicular to the support frame (2); Step 303: Install the auxiliary support mechanism at the top of the hinge axis of each hinge connection mechanism; Step 4: Deploy multiple electronic angle measuring instruments (9) and multiple laser rangefinders (10); Step 5: Use an intelligent control device to control and calibrate the radius of curvature of the arc-shaped template. The specific process includes: Step 501: Determine a reference template among the multiple standardized templates (1), and first adjust the actual length of the electric linear actuator (3) connected to the reference template so that the actual length of the electric linear actuator (3) on the reference template is... Equal to the theoretical length of the electric linear actuator (3) on the reference template Then, the reference template is fixed onto the bottom template. Step 502: Using the reference template as a reference, simultaneously adjust the actual length of the electric linear actuator (3) connected to the remaining standardized templates (1) and the actual splicing angle between any two adjacent standardized templates (1): The laser rangefinder (10) transmits the actual length of the electric linear push rod (3) measured in real time to the controller. The electronic angle measuring instrument (9) transmits the actual splicing angle between any two adjacent standardized templates (1) measured in real time to the controller. The controller calculates and compares the actual data with the theoretical data. By controlling the first drive motor to drive the electric linear push rod (3) to extend and retract, and the second drive motor (7-1) to drive the two support arms (6-1) to deflect, the support arms (6-1) drive the vertical connecting rod (6-2) and the auxiliary push plate (6-3) to push the two adjacent standardized templates (1), thereby realizing the adjustment of the actual splicing angle between the two adjacent standardized templates (1).
