Technical Field
[0001] This utility model belongs to the field of masonry structure technology, specifically relating to an externally mounted masonry wall reinforcement and shock absorption device with replaceable mass damping. Background Technology
[0002] In recent years, the frequency of earthquakes has increased significantly due to the movement of tectonic plates, severely impacting buildings in my country and causing enormous disruption to people's lives and livelihoods. To address the shortcomings of various masonry structures, such as poor stability and inadequate earthquake resistance, it is necessary to strengthen and improve them. Masonry structure strengthening involves reinforcing, partially replacing, or adjusting the internal forces of masonry structures, components, and related parts that lack sufficient reliability or where the owner requires increased reliability. This ensures they meet the safety, durability, and applicability requirements of current design codes and the owner's specifications. External surface layer reinforcement is commonly used in masonry structure strengthening to improve the load-bearing capacity and stiffness of the original components.
[0003] When reinforcing existing masonry structures using reinforced concrete surface layer reinforcement, to enhance the overall stability of the original masonry structure, it is necessary to install rebar and L-shaped anchoring rebars on the original masonry structure to ensure the connection and anchorage between the original masonry and the newly added slab wall structure. Simultaneously, during the construction of the new concrete slab wall, drilling, installation, and formwork fixing of tie rods are required for supporting and fixing the formwork before pouring concrete. However, when the original exterior wall needs protection, only single-sided formwork can be used. In this case, tie rods need to be installed in the original masonry structure, or single-sided formwork without tie rods can be used. This method usually requires steel formwork with high rigidity. However, this method has the following problems: high construction cost, poor concrete forming quality, and the risk of the original structure loosening and collapsing during concrete pouring. If conventional tie rods are used, the bolt holes need to be sealed after construction, increasing construction costs and time, and there is also a risk of leakage. Furthermore, simply reinforcing the structure with rigidity to resist earthquake damage cannot effectively dissipate external loads and often increases repair costs, which is inconsistent with the current green and environmentally friendly building concepts.
[0004] In some masonry structures, due to limitations in design theory, building materials, and construction conditions, the building materials used, construction quality, structural seismic bearing capacity, and construction methods do not meet the requirements of current specifications, which greatly affects the safety of the structure. The mortar strength of many walls is too low, and the walls must be reinforced before they can continue to be used. Utility Model Content

The two lower swing shafts 502 are fixedly connected to the outer walls of the two slide rail sleeves 10 respectively.
[0024] The replaceable mass damping external masonry wall reinforcement and shock absorption device provided by this utility model works as follows: When encountering a small earthquake, the building as a whole causes the masonry wall to vibrate slightly. The masonry wall 1 and the steel frame embedded in the wall are a whole, causing the structure to vibrate. At this time, the external load is transmitted from the wall to the upper steel frame 2 and the lower steel frame 3, and then to the disc-shaped weight 7 through the spring telescopic rod 6. The disc-shaped weight 7 sways up and down under the action of the external load. The spring in the spring telescopic rod 6 consumes the seismic energy, which plays the role of shock absorption and energy dissipation for the masonry wall 1. During a moderate earthquake, the disc-shaped weight 7 sways significantly under external load. At this time, the springs inside the spring-loaded telescopic rod 6, along with the lower energy-dissipating device, work together. The disc-shaped weight 7 presses against the slide rail support 15, which transmits the external force from the first steel plate 1301 and the second steel plate 1302 to the lower slide rail sleeve 10. Under the action of the external force, the slide rail sleeve 10 slides down to both sides of the lower slide rail 9, generating friction with the lower slide rail 9 while simultaneously compressing the spring 14 inside the L-shaped fixing sleeve 11. The overall structure, due to the change in the center of gravity caused by the vertical displacement of the disc-shaped weight 7 and the stretching of the spring 14, dissipates seismic energy, thus protecting the wall and reducing earthquake damage. Furthermore, the rubber layer covering the disc-shaped weight 7 also provides sound insulation against the impacts caused by the vertical displacement of the weight. During a severe earthquake, the disc-shaped weight 7 will not only displace vertically but also horizontally. At this time, the spring-loaded telescopic rod 6 drives the disc-shaped weight 7 to swing left and right on the arc-shaped slide rail 8. The arc-shaped groove of the slide rail 8 limits the swing direction of the disc-shaped weight 7, thereby reducing the damage to the overall wall structure caused by the swing. The rubber layer wrapped around the outside of the disc-shaped weight 7 also dissipates energy through friction on the track. When a large external load causes the masonry wall to tilt, the wall compresses the steel frame, and the reinforcing steel pipe 4 supports the wall and the overall device to delay brittle failure of the wall, buying time for evacuation and repair. After the earthquake, the soundproof panel 12 can be removed, and the energy-dissipating devices inside the steel frame can be removed and replaced.
