Description
Technical Field
[0001] This utility model belongs to the technical field of prefabricated buildings, specifically relating to a seismic reinforcement device for prefabricated masonry structures. Background Technology
[0002] In the field of seismic resistance of buildings, prefabricated masonry structures are widely used due to their convenient construction and economical cost. However, due to limitations in material properties and connection methods, their seismic performance has always been a key challenge in engineering practice. Under seismic loads, the corners and connections of traditional prefabricated masonry structures are prone to becoming weak points. On the one hand, existing reinforcement devices mostly use dispersed metal connecting strips, and the independent stress on each connecting strip leads to significant stress concentration. During an earthquake, the failure of a single connecting strip can easily cause the entire reinforcement system to fail. On the other hand, the anchoring methods between the connecting strips and the wall mostly rely on surface bonding or single-point anchoring. The anchoring depth is insufficient and the force transmission path is singular, making it difficult to effectively transfer seismic loads to the building body, resulting in poor collaborative working ability between the reinforcement layer and the original structure.
[0003] Especially in earthquake-prone areas, corner joints of prefabricated masonry structures often exhibit a disaster pattern of "local damage leading to overall collapse" due to the lack of reliable overall reinforcement measures. For example, in traditional reinforcement, metal connecting strips are only connected to the corner reinforcement angle steel by welding, failing to form a continuous planar support system. During an earthquake, the horizontal force cannot be evenly distributed, easily leading to cracking of the connecting strip welds. At the same time, the anchoring of the connecting strips to the wall often uses surface fixing methods such as expansion bolts, and the anchoring force is greatly affected by the strength of the wall substrate, making it prone to loosening and falling off under repeated seismic loads. Utility Model Content

The failure of a single strip may cause the collapse of the entire reinforcement system. In addition, the anchoring of the connecting strip to the wall often relies on surface bonding or single-point anchoring, which results in insufficient anchoring depth, single force transmission path, and difficulty in the reinforcement layer and the original structure working together.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] This utility model provides, for example Figure 1-5 The prefabricated masonry structure seismic reinforcement device shown includes a building assembly corner reinforcement angle steel 6 and a wall reinforcement metal strip B5 disposed on the left side of the building assembly corner reinforcement angle steel 6. A wall reinforcement metal strip A10 is disposed on the rear right end of the building assembly corner reinforcement angle steel 6. The building assembly corner reinforcement angle steel 6 is sleeved on the outside of the corner of the two building walls assembled at a right angle. Multiple metal reinforcement connecting strips B9 are equidistantly connected to the front outer wall of the building assembly corner reinforcement angle steel 6 and the wall reinforcement metal strip B5. The two ends of the multiple metal reinforcement connecting strips B9 are connected to the building assembly corner reinforcement angle steel 6 and the wall reinforcement metal strip B5. All five are fixedly connected by welding. Multiple metal reinforcing connecting strips A11 are equidistantly connected to the right outer wall of the corner reinforcement angle steel 6 and the wall reinforcement metal strip A10. Both ends of the multiple metal reinforcing connecting strips A11 are fixedly connected to the corner reinforcement angle steel 6 and the wall reinforcement metal strip A10 by welding. Multiple anchor bar installation holes 7 are equidistantly provided at the front end and right end of the corner reinforcement angle steel 6, inside the wall reinforcement metal strip B5, and inside the wall reinforcement metal strip A10. The multiple anchor bar installation holes 7 inside the front end and right end of the corner reinforcement angle steel 6 are staggered. Anchor bars are inserted into multiple anchor installation holes 7, and the corner reinforcement angle steel 6, wall reinforcement metal strip B5, and wall reinforcement metal strip A10 are all fixedly connected to the prefabricated building wall through multiple anchor bars. This device is designed for seismic reinforcement of prefabricated masonry structures. Utilizing the principle of multiple mechanical connections and synergistic force distribution, the corner reinforcement angle steel 6 is sleeved onto the wall corner, and the wall reinforcement metal strips A10 and B5 are attached to the wall surface to form an enclosed support frame. The metal reinforcement connecting strips A11 and B9 are welded to the corner reinforcement angle steel and the wall reinforcement on both sides. The metal strips are connected to form a triangular stable force transmission system of "corner-wall-connecting strip". The stress generated by the seismic load is distributed and transmitted to the reinforcement device along the wall surface and corner nodes, avoiding local stress concentration in the masonry. The anchor bars are inserted into the anchor bar installation holes 7 of each component and fixed to the wall. The mechanical interlocking force of the anchor bars strengthens the anchoring connection between the reinforcement device and the masonry structure, allowing the reinforcement system to work in synergy with the original structure and improving the overall resistance to lateral displacement and overturning. Angle steels A1 and B and triangular reinforcement plates 2 are installed on the ground to increase the connection strength between the device and the ground foundation, limit the displacement of the bottom of the structure, and further enhance the seismic stability.
[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the corner reinforcement angle steel 6 of the building assembly is connected to the outer wall of the bottom front end of the wall reinforcement metal strip B5 by a ground-mounted angle steel B3. The ground-mounted angle steel B3 is fixedly connected to the corner reinforcement angle steel 6 and the wall reinforcement metal strip B5 by welding. The corner reinforcement angle steel 6 of the building assembly is connected to the outer wall of the bottom right end of the wall reinforcement metal strip A10 by a ground-mounted angle steel A1. The ground-mounted angle steel A1 is fixedly connected to the corner reinforcement angle steel 6 and the wall reinforcement metal strip A10 by welding. For fixed connections, the bottom outer walls of ground-mounted angle steel A1 and ground-mounted angle steel B3 are flush. Triangular reinforcing plates 2 are welded to the inner corners of both ends of ground-mounted angle steel A1 and the inner corners of both ends of ground-mounted angle steel B3. Multiple angle steel mounting holes 4 are provided inside the bottom ends of both ground-mounted angle steel A1 and ground-mounted angle steel B3. When installing seismic reinforcement devices on prefabricated masonry structures, holes are first drilled in the corresponding positions of the building walls using a drilling rig to prepare metal rod insertion holes (if overall reinforcement of connecting strips is involved). This step is required for device 8. The basic steps of this device include preparing the holes needed for anchor bar installation, cleaning debris from the wall surface and corners to ensure the surfaces of the reinforcing components are clean, and then fitting the corner reinforcing angle steel 6 onto the wall corner, ensuring that the wall reinforcing metal strips A10 and B5 are respectively attached to their corresponding wall surfaces. Through welding, the ends of the metal reinforcing connecting strips A11 and B9 are fixed to the corner reinforcing angle steel and the wall reinforcing metal strips, respectively, forming a preliminary frame. Insert the anchor bars into the anchor bar installation holes 7 of the corner reinforcement angle steel 6, wall reinforcement metal strip A10, and wall reinforcement metal strip B5. Fix the anchor bars using an adapter method to ensure a reliable connection between the reinforcement device and the wall. Finally, weld the ground installation angle steel A1 and ground installation angle steel B3 to the bottom of the corresponding reinforcement components. Connect the ground installation angle steel to the ground foundation at the bottom angle steel installation hole 4 using bolts or other methods. Weld the triangular reinforcement plate 2 to the inner corner of the ground installation angle steel to complete the overall reinforcement.
[0024] like Figure 1 , Figure 4 and Figure 5As shown, multiple metal reinforcing connecting strips B9 are connected to their rear ends and multiple metal reinforcing connecting strips A11 to their left ends by an integral reinforcing device 8. The integral reinforcing device 8 at the rear end of the metal reinforcing connecting strips B9 includes an integral reinforcing metal strip 12, a building insertion metal rod 13, and symmetrical clamping metal blocks 14. The integral reinforcing metal strip 12 is vertically arranged at the rear end of the multiple metal reinforcing connecting strips B9 and is attached to the front outer wall of the building wall. Multiple building insertion metal rods 13 are welded at equal intervals to the rear end of the integral reinforcing metal strip 12. Multiple sets of symmetrical clamping metal blocks 14 are welded at equal intervals to the front outer wall of the integral reinforcing metal strip 12. Each set of symmetrical clamping metal blocks 14 consists of two separate clamping metal blocks, and each set of symmetrical clamping metal blocks 14 clamps the metal reinforcing connecting strip B9 corresponding to its position, i.e., two separate clamping metal blocks. Metal blocks are clamped at the upper and lower ends of the center of the metal reinforcing connecting strip B9. Multiple metal rod insertion holes are equidistantly arranged inside the front end of the building wall by drilling. Multiple building insertion metal rods 13 are inserted into the metal rod insertion holes corresponding to their positions, and there is an interference fit between the building insertion metal rods 13 and the metal rod insertion holes. The mechanical interlocking force and frictional resistance between the metal rods and the hole walls are used to transfer the load of the reinforcement device to the wall substrate. This design creates a vertical force transmission path, so that the reinforcement device not only adheres to the wall surface, but also forms a mechanical community with the original structure through anchoring. When an earthquake occurs, the horizontal seismic force is transferred to the metal reinforcing connecting strip B9 through the corner reinforcing angle steel and the wall reinforcing metal strip. After being integrated by the overall reinforcing metal strip 12, it is dispersed to the interior of the wall by the building insertion metal rods 13, so as to avoid stress concentration at the interface between the reinforcement layer and the wall.
[0025] like Figure 1 , Figure 4 and Figure 5As shown, the overall reinforcing device 8 for the connecting strip also includes connecting strip connecting holes 15 and connecting strip metal connecting plugs 16. Each of the multiple sets of symmetrically clamping metal blocks 14 has a connecting strip metal connecting plug 16 inside, and the connecting strip metal connecting plug 16 is located between the centers of the two clamping metal blocks constituting the symmetrically clamping metal blocks 14. The connecting strip metal connecting plug 16 is fixedly connected to the overall reinforcing metal strip 12 by welding. Each of the multiple metal reinforcing connecting strips B9 has a connecting strip connecting hole 15 inside its center, and the connecting strip metal connecting plug 16 is inserted into the connecting strip connecting hole 15. The device uses the overall reinforcing metal strip 12 as the core load-bearing component. It is vertically attached to the surface of the building wall and horizontally connected with multiple dispersed metal reinforcing connecting strips B9 to form a continuous planar support system. The metal blocks 14 are symmetrically clamped with a "double clamping block + center plug" structure to hold the metal reinforcing connecting strips B9 tightly from the top and bottom. At the same time, the metal connecting plugs 16 of the connecting strips are precisely inserted into the pre-set connecting holes 15 of the metal reinforcing connecting strips B9 and fixed by welding to form a rigid node. This composite connection method of "clamping + plugging" transforms the independent metal reinforcing connecting strips B9 into a co-force-bearing overall frame, making the stress distribution between the connecting strips more uniform under seismic action and avoiding the failure of a single strip due to stress concentration.
[0026] like Figure 1 , Figure 4 and Figure 5 As shown, both the metal connector 16 and the building insertion metal rod 13 are solid metal rods. After the metal connector 16 is fully inserted into the connecting hole 15, it is flush with the outer wall of the front end of the metal reinforcing connector B9. The overall reinforcing device 8 uses symmetrical clamping metal blocks 14 to mechanically clamp the metal reinforcing connector B9. Combined with the insertion of the metal connector 16 into the connecting hole 15, this connects the dispersed metal reinforcing connectors B9 laterally into a continuous whole, strengthening... The device integrates the force transmission between the connecting strips. At the same time, with the interference fit between the building plug-in metal rod 13 and the pre-set metal rod insertion hole in the building wall, the metal reinforcing connecting strip B9 is anchored to the building wall in the longitudinal direction, constructing a three-dimensional force transmission path of "connecting strip-reinforcing strip-wall". During an earthquake, the device can integrate the force of each metal reinforcing connecting strip, avoid stress concentration failure of a single connecting strip, and can also transmit the seismic load borne by the reinforcement device to the building body more evenly through anchoring with the wall, thus synergistically improving the seismic redundancy and overall stability of the prefabricated masonry structure.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
