Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of prestressed wood arch construction, in particular to a supporting device and method for prestressed wood arch construction. BACKGROUND

[0002] Currently, there are three methods for installing and supporting wood arches in large-span hybrid wood-arch steel frame structures of large public buildings. The first method is the full-support method, which involves setting up a dense steel pipe scaffold as a temporary support platform under the wood arch, and then hoisting and assembling the wood arch components in segments or as a whole. The second method is the segmented hoisting and temporary support tower method, which involves dividing the wood arch into segments and installing temporary steel support towers at the segment interfaces, and then hoisting and assembling the segments one by one to form a whole. The third method is the whole lifting / jacking method, which involves assembling the wood arch into a whole on the ground, and then lifting it to the designed elevation using hydraulic lifting equipment or a jacking system, and connecting it with the steel frame and the cable.

[0003] The first method has high material consumption and foundation treatment costs, poor economic efficiency, long scaffold erection period, high risk of dismantling, and is easily affected by rain, snow, and strong winds. It also has technical limitations, is greatly affected by scaffold erection height and measurement errors, and is difficult to control. The second method is prone to internal stress redistribution during system transformation, causing the main structure to lose stability and be damaged. It is also difficult to control the installation precision when high-altitude docking and assembly are affected by temperature changes. In addition, when welding the operation platform, there is a risk of wood ignition by welding slag. The third method requires high-quality professional equipment and a ground assembly site, resulting in high construction costs. When multiple lifting points are installed simultaneously, wind-induced vibration is likely to occur, making control complex. When the lifting is not synchronized, stress concentration is likely to occur in the wood arch structure, and it is difficult to repair such deviations, which is a permanent damage.

The fastening toothed plate (521) slides within the mounting box (511) and has multiple inclined surfaces (522) that abut against the inclined surface one (514). The inclined surfaces (522) are inclined upward. One end of the fastening threaded rod (523) is rotatably connected to the fastening toothed plate (521), and the other end of the fastening threaded rod (523) passes through the mounting box (511). The fastening block (524) is rotatably mounted on the mounting box (511) and is threadedly connected to the fastening threaded rod (523).

9. The support device for prestressed timber arch construction according to claim 8, characterized in that, The detachment detection module (53) includes a detection rotating rod (531), one end of which is hinged to the upper side of the support block (513). A torsion spring is sleeved on the hinge shaft between the detection rotating rod (531) and the support block (513), and the two elastic legs of the torsion spring abut against the detection rotating rod (531) and the support block (513) respectively.

10. A support method, utilizing the support device for prestressed timber arch construction as described in claim 9, characterized in that, Includes the following steps: Step 1: After the steel structure (61) is completed, multiple sets of sliding platforms (71) are erected on the ground in a direction perpendicular to the steel structure (61), and conformal support frames (72) are erected on the sliding platforms (71); then the mounting plate (1) is welded together with the conformal support frame (72); Step 2: Divide the wooden arch (62) installed at the bottom of the steel structure (61) into five segments. Use a truck crane to lift the wooden arch (62) to be assembled into place. Move the void detection module (53) to one side so that the void detection module (53) is blocked by the bottom of the wooden arch (62). Then operate the adjustment structure (4) so ​​that the support module (51) contacts the wooden arch (62) and automatically adapts to the curvature of the bottom of the wooden arch (62). Step 3: Adjust the fastening module (52) to lock the support module (51); Step 4: After the wooden arch (62) is assembled and installed, during the prestressed grade tensioning and load holding process of the wooden arch (62), the support point will be detached due to the redistribution of internal stress. The detachment detection module (53) on the support module (51) will be reset. Construction workers can determine the support status of the corresponding position by detecting the status of the module (53); this allows construction workers to quickly adjust the adjustment structure (4) at the corresponding position so that the support module (51) on the adjustment structure (4) can support the wooden arch (62) again.
