Description

Technical Field

[0001] This utility model belongs to the field of building structure reinforcement technology, specifically an ECC building structure reinforcement connector. Background Technology

[0002] ECC building structures are a new type of building structure system that uses engineering cement-based composite materials as key structural materials. They are typically used in the main frame structure of high-rise buildings, which can improve energy absorption capacity and reduce the need for repairs after earthquakes.

[0003] The ECC building structure system includes intersecting beams and columns, both of which are composed of ECC material, longitudinal reinforcement, and stirrups. This type of component is used in critical seismic locations, especially key joints. Compared to ordinary reinforced concrete components, it significantly improves the ductility and seismic performance of the structure. While meeting seismic requirements, it greatly reduces the use of stirrups at joints, solving construction difficulties caused by excessively dense stirrups in the joint area.

[0004] Through long-term use and observation, it was found that when two sets of beams were used together in an ECC building structure, the unstable connection of the beams led to a reduction in the overall stiffness of the structure, thus affecting the stability of the structure.

[0005] Therefore, this utility model provides an ECC building structure reinforcement connector. Utility Model Content

The first crossbeam has multiple first short screws threaded into its main body; a pair of second pipe clamps are snapped into the middle of the side wall of the second crossbeam; the second pipe clamps and the first pipe clamps are correspondingly set; multiple second short screws are threaded into the middle of the side wall of the second pipe clamp; a connecting plate is fixed between adjacent first and second pipe clamps; long screws are threaded into the connecting plate and both the first and second crossbeams; this step of setting the first pipe clamps, first short screws, second pipe clamps, second short screws, connecting plate, and long screws can firmly connect the two crossbeams together to form a whole. This connection method can improve the connection strength between the crossbeams, enabling the structure to work better together when bearing loads, reducing the risk of damage caused by excessive local stress, and strengthening the lap relationship of the crossbeams, which is equivalent to increasing the constraint conditions of the structure, making the structure more stable under stress, helping to reduce structural deformation, improve the overall stiffness of the structure, and thus enhance the load-bearing capacity of the structure.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 4 As shown, an embodiment of the present invention provides an ECC building structure reinforcement connector, including a first crossbeam 1; a second crossbeam 11 overlaps the middle of the side wall of the first crossbeam 1; a connecting component is provided at the middle of the side wall of both the first crossbeam 1 and the second crossbeam 11, which can reinforce the connection between the first crossbeam 1 and the second crossbeam 11; a limiting component is provided between the connecting component and the first crossbeam 1 and the second crossbeam 11, which can limit the range of motion of the connecting component on the first crossbeam 1 or the second crossbeam 11; a tensioning component is provided between adjacent connecting components, which can further limit the movement of the connecting components; adjacent connecting components... A support component is provided between the connecting components to support the connecting components. The construction workers overlap the first crossbeam 1 and the second crossbeam 11, and then, under the action of the limiting component, the connecting components are respectively snapped onto the side walls of the first crossbeam 1 and the second crossbeam 11. At this time, the connecting components will strengthen the connection relationship between the first crossbeam 1 and the second crossbeam 11. After the position of the connecting components is fixed, the tension component and the support component will simultaneously restrict the position of the connecting components, strengthen the stability of the connecting components on the first crossbeam 1 and the second crossbeam 11, and make the connecting components more firmly connect the first crossbeam 1 and the second crossbeam 11 together.

[0026] like Figures 1 to 4As shown, the connecting assembly includes a first pipe clamp 2; the first pipe clamp 2 is a pair and symmetrically arranged on the side wall of the first crossbeam 1; the pair of first pipe clamps 2 are snapped onto the side wall of the first crossbeam 1; a plurality of first short screws 21 are threadedly connected to the middle of the side wall of the first pipe clamp 2; a pair of second pipe clamps 22 are snapped onto the middle of the side wall of the second crossbeam 11; the second pipe clamps 22 and the first pipe clamps 2 are correspondingly arranged; a plurality of second short screws 23 are threadedly connected to the middle of the side wall of the second pipe clamp 22; a connecting plate 24 is fixed between adjacent first pipe clamps 2 and second pipe clamps 22; long screws 25 are threadedly connected between the connecting plate 24 and the first crossbeam 1 and the second crossbeam 11; after the first crossbeam 1 and the second crossbeam 11 are overlapped together, the construction personnel symmetrically snap the pair of first pipe clamps 2 onto the side wall of the first crossbeam 1, and use a plurality of first short screws 21 to lock the first pipe clamps 2, so that the first pipe clamps 2 are tightly snapped onto the side wall of the first crossbeam 1, and then symmetrically snap the pair of second pipe clamps 22 onto the second crossbeam 1. On the side wall of the first crossbeam 11, multiple second short screws 23 are used to lock the second pipe clamp 22, so that the second pipe clamp 22 is tightly fastened to the side wall of the second crossbeam 11. Then, multiple long screws 25 are used to fix the connecting plate 24 to the side wall of the first pipe clamp 2 and the second pipe clamp 22 respectively. At this time, the first crossbeam 1 and the second crossbeam 11 will be firmly connected together. This step of setting the first pipe clamp 2, the first short screw 21, the second pipe clamp 22, the second short screw 23, the connecting plate 24 and the long screws 25 can firmly connect the two crossbeams together to form a whole. This connection method can improve the connection strength between the crossbeams, so that the structure can work better together when bearing loads, reduce the risk of damage caused by excessive local stress, and strengthen the lap relationship of the crossbeams, which is equivalent to increasing the constraint conditions of the structure, making the structure more stable when under stress, helping to reduce the deformation of the structure, improve the overall stiffness of the structure, and thus enhance the load-bearing capacity of the structure.

[0027] like Figures 1 to 4As shown, the limiting assembly includes two sets of fixing rings 3; the fixing rings 3 are respectively welded to the side walls of the first crossbeam 1 and the second crossbeam 11; one set of fixing rings 3 is located between the first crossbeam 1 and the first pipe clamp 2; the other set of fixing rings 3 is located between the second crossbeam 11 and the second pipe clamp 22; multiple limiting grooves 31 are opened in the middle of the side wall of the fixing ring 3; multiple limiting blocks 32 are fixed in the middle of the inner side wall of the first pipe clamp 2 and the second pipe clamp 22; the limiting blocks 32 and the limiting grooves 31 are correspondingly arranged; before the first pipe clamp 2 and the second pipe clamp 22 are respectively fastened to the side walls of the first crossbeam 1 and the second crossbeam 11, multiple fixing rings 3 are first welded to the side walls of the first crossbeam 1 and the second crossbeam 11, at this time the fixing rings 3 are connected to the first crossbeam 1 or the first pipe clamp 22. The two crossbeams 11 form a whole. Then, the first pipe clamp 2 and the second pipe clamp 22 are respectively fastened to the side wall of the fixing ring 3. Since the limiting block 32 and the limiting groove 31 are set accordingly, when fastening the first pipe clamp 2 and the second pipe clamp 22, the multiple limiting blocks 32 on the side wall of the first pipe clamp 2 and the second pipe clamp 22 are first fastened to the corresponding inside the limiting groove 31, and then the first pipe clamp 2 or the second pipe clamp 22 is locked. This step can limit the position of the first pipe clamp 2 and the second pipe clamp 22 on the crossbeam by setting the fixing ring 3, the limiting groove 31 and the limiting block 32. Through physical constraints, the relative displacement or misalignment of the crossbeam and the first pipe clamp 2 and the second pipe clamp 22 caused by external forces is effectively prevented, and the overall stability of the structure is further improved.

[0028] like Figures 1 to 4 As shown, the tensioning assembly includes multiple fixing blocks 4; the fixing blocks 4 are fixed to the side wall of the fixing ring 3; multiple telescopic rods 41 are installed between adjacent fixing blocks 4; multiple first damping springs 42 are installed between adjacent fixing blocks 4; the first damping springs 42 are covered outside the telescopic rods 41; when the construction personnel pull the multiple telescopic rods 41 and the first damping springs 42 and fix them between adjacent fixing rings 3, the telescopic rods 41 and the first damping springs 42 will generate tension force on the adjacent fixing rings 3 and the first pipe clamps 2 or second pipe clamps 22 on their side walls. When the beam is subjected to periodic loads, this step, by setting the fixing blocks 4, telescopic rods 41 and first damping springs 42, can adjust the natural frequency of the system, reduce resonance caused by the overlap with the excitation frequency, extend the structural life, and this setting can evenly distribute the concentrated load borne by the beam to the connected first pipe clamps 2 or second pipe clamps 22, reduce fatigue failure caused by excessive local stress, reduce shear stress at the connection between the beam and the first pipe clamps 2 and second pipe clamps 22, and reduce the risk of bolt loosening or breakage.

[0029] like Figure 1As shown, the support assembly includes multiple support plates 5; the support plates 5 are fixed to the side wall of the connecting plate 24; multiple second damping springs 51 are fixed between the support plates 5 and the connecting plate 24; after the connecting plate 24 is fixed, the construction personnel fix the support plates 5 to the side wall of the connecting plate 24, and at the same time install multiple second damping springs 51 between the support plates 5 and the connecting plate 24. By setting the support plates 5 and the second damping springs 51, under sudden impact loads, the multiple second damping springs 51 can absorb some energy, reduce the transient impact on the connecting plate 24 and the crossbeam, and improve the impact resistance of the connecting plate 24 and the crossbeam.

[0030] like Figure 1 and Figure 2 As shown, an elastic band 6 is fixed between adjacent connecting plates 24; multiple elastic bands 6 are respectively set with the first crossbeam 1 and the second crossbeam 11; the elastic band 6 is made of elastic material; this step, by setting multiple elastic bands 6, can externally clamp the first crossbeam 1 and the second crossbeam 11. During vibration, the elastic band 6 consumes energy through friction and elastic deformation, reducing the vibration amplitude and frequency of the crossbeam, and further improving the impact resistance of the connecting plate 24 and the crossbeam.

[0031] like Figure 4 As shown, anti-slip pads 7 are fixed between the fixing ring 3 and the first pipe clamp 2 and the second pipe clamp 22. The anti-slip pads 7 are made of elastic material. This step can increase the static friction between the fixing ring 3 and the first pipe clamp 2 and the second pipe clamp 22 by using anti-slip pads 7 with a high coefficient of friction, preventing relative sliding caused by external forces, and strengthening the connection between the crossbeams. At the same time, the anti-slip pads 7 can fill the small gaps between the fixing ring 3 and the first pipe clamp 2 and the second pipe clamp 22, so that the load is evenly distributed and local stress concentration is reduced.

[0032] Working principle: Construction workers overlap the first crossbeam 1 and the second crossbeam 11. Then, under the action of the limiting component, the connecting component is respectively snapped onto the side walls of the first crossbeam 1 and the second crossbeam 11. At this time, the connecting component will strengthen the connection between the first crossbeam 1 and the second crossbeam 11. After the position of the connecting component is fixed, the tension component and the support component will simultaneously restrict the position of the connecting component, strengthen the stability of the connecting component on the first crossbeam 1 and the second crossbeam 11, and make the connecting component more firmly connect the first crossbeam 1 and the second crossbeam 11 together. After beams 11 are joined together, the construction workers symmetrically fasten a pair of first pipe clamps 2 onto the side wall of the first crossbeam 1, and use multiple first short screws 21 to lock the first pipe clamps 2, so that the first pipe clamps 2 are tightly fastened to the side wall of the first crossbeam 1. Then, a pair of second pipe clamps 22 are symmetrically fastened onto the side wall of the second crossbeam 11, and multiple second short screws 23 are used to lock the second pipe clamps 22, so that the second pipe clamps 22 are tightly fastened to the side wall of the second crossbeam 11. Subsequently, multiple long screws 25 are used to fix the connecting plate 24 to the side walls of the first pipe clamps 2 and the second pipe clamps 22 respectively. At this time, the first crossbeam 1 and the second crossbeam 1 are joined together. The two crossbeams 11 will be securely connected together. Before the first pipe clamp 2 and the second pipe clamp 22 are respectively fastened to the side walls of the first crossbeam 1 and the second crossbeam 11, multiple fixing rings 3 are first welded to the side walls of the first crossbeam 1 and the second crossbeam 11. At this time, the fixing rings 3 form a whole with the first crossbeam 1 or the second crossbeam 11. Then, the first pipe clamp 2 and the second pipe clamp 22 are respectively fastened to the side walls of the fixing rings 3. Because the limiting block 32 and the limiting groove 31 are correspondingly set, when fastening the first pipe clamp 2 and the second pipe clamp 22, the multiple limiting blocks on the side walls of the first pipe clamp 2 and the second pipe clamp 22 are first fastened. Block 32 is snapped into the limiting groove 31, and then the first pipe clamp 2 or the second pipe clamp 22 is locked. The construction workers pull multiple telescopic rods 41 and the first damping spring 42 and fix them between adjacent fixed rings 3. At this time, the telescopic rods 41 and the first damping spring 42 will generate a pulling force on the adjacent fixed rings 3 and the first pipe clamp 2 or the second pipe clamp 22 on their side walls. When the crossbeam is subjected to periodic load, after the connecting plate 24 is fixed, the construction workers fix the support plate 5 on the side wall of the connecting plate 24, and at the same time install multiple second damping springs 51 between the support plate 5 and the connecting plate 24.
