Problems solved by technology

This method is relatively easy to implement for materials such as steel bars and steel strands, but for sheet materials such as steel plates, fiber cloth or fiberboards, the anchorage is relatively difficult, and the fiber material is brittle and easy to break, so the traditional prestressing method has limitations. sex

Abstract

The invention relates to a prestress applying device and method for reinforcing a laminated wood beam. The applying device comprises a transverse pressurizing device and a longitudinal pressurizing device. The longitudinal pressurizing device is used in cooperation with the transverse pressurizing device, the longitudinal pressurizing device enables the wood beam to be capable of applying prestress outside the wood beam, the integrity of the section is not damaged, and the transverse pressurizing device enables a reinforcing material and the wood beam to be pressed so as to guarantee the pasting quality. The prestress applying device is small in size and convenient and fast to operate, the reinforcing material pasting process and the prestress applying process can be combined, the integrity of the section is not damaged, and therefore the height of the section of the laminated wood beam can be reduced, materials are saved, construction is convenient, and the application range of the laminated wood beam can be widened. The problems that the common working performance of the wood beam and the reinforcing material is poor, local glue failure and prestress applying are inaccurate are solved, and the manufacturing quality of the prestress reinforcing beam is guaranteed.

Description

technical field [0001] The invention relates to the technical field of wood structures in civil engineering, in particular to a prestressing device and method for reinforcing glued wood beams. Background technique [0002] Glulam is usually composed of wooden veneers, veneer strips or wood chips arranged along the length direction of the components, and laminated with structural adhesives. It is the main material of modern wood structures. The glued wood structure has been widely used in Europe and the United States because of its advantages such as renewable materials, green energy saving and environmental protection, reliable force, good seismic performance, high degree of industrialization, short construction period, moisture-proof and anti-corrosion, sound insulation and noise-proof, and good fire resistance. application. In recent years, in order to save energy, protect the environment and achieve sustainable development, my country has also vigorously promoted green b...
