They play a key role in steel structure buildings, ensuring the stability and load-bearing capacity of the structure. The design and construction of I-beam joints need to consider a variety of factors, including load-bearing capacity, stiffness, seismic performance, construction convenience, and cost.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figures 1 to 4 The utility model provides a technical solution: a rigidity-reinforced anti-circumvention I-beam joint, comprising a left wing plate 1, the left wing plate 1 is welded to the left side of a web 2, a right wing plate 3 is welded to the right side of the web 2, the right wing plate 3 and the left wing plate 1 are both provided with anti-circumvention iron sheets 4, a steel wire brush 5 is provided on the opposite inner side of the anti-circumvention iron sheet 4, the opposite side of the steel wire brush 5 is tightly fitted to the outer wall of a wall 6, and oblique tension bars 7 are welded between the right wing plate 3 and the opposite sides of the left wing plate 1 and the web 2.
[0022] In this embodiment, Figure 1 and Figure 2As shown, the right wing plate 3 and the left wing plate 1 form a reinforcement structure with the web 2 through the oblique tie bars 7; it should be noted that, in order to enhance the rigidity of the I-beam joint body, the utility model welds oblique tie bars 7 at the opposite side angles between the left wing plate 1 and the right wing plate 3 and the web 2, respectively. In actual use, the oblique tie bars 7 can provide additional lateral support, effectively enhancing the overall rigidity and stability of the I-beam, especially when subjected to lateral loads, and by welding the oblique tie bars 7 at the opposite side angles between the left wing plate 1, the right wing plate 3 and the web 2, the bending resistance of the I-beam joint can be significantly improved, so that it can withstand greater bending stress, and at the same time effectively prevent the wing plates and the web 2 from local buckling when subjected to force, which helps to maintain the integrity and bearing capacity of the structure, and the oblique tie bars 7 can guide and disperse the load, ensure that the load is evenly distributed on various parts of the I-beam, thereby avoiding local stress concentration, improving the stability of the overall structure, and enabling the I-beam joint to better resist the influence of fatigue and environmental factors during long-term use, thereby improving the durability of the structure.
[0023] In this embodiment, Figure 4 As shown, the cross-sectional thickness of the right wing plate 3, the left wing plate 1 and the web 2 near the bottom of the pit is increased; it should be noted that, in addition to the oblique tie bars 7 provided at the relative side angles of the left wing plate 1, the right wing plate 3 and the web 2, the utility model also increases the cross-sectional thickness of the left wing plate 1, the right wing plate 3 and the web 2 near the bottom of the pit, thereby increasing their overall height and effectively preventing them from deforming. In actual use, increasing the cross-sectional thickness of the right wing plate 3, the left wing plate 1 and the web 2 can significantly improve the stiffness and bearing capacity of the I-beam joint. When subjected to heavy loads or impact loads, the enhanced cross-section can provide stronger bending and shear resistance. At the same time, the enhanced cross-section helps to reduce stress concentration, thereby improving the fatigue resistance of the structure and extending the service life of the I-beam. In addition, increasing the cross-sectional thickness can enhance the local stability of the I-beam joint. In complex stress areas such as the bottom of the pit, it can effectively prevent buckling or deformation under high stress, and help prevent concrete from bypassing the joint during pouring, ensuring that the concrete can be evenly filled and reducing structural defects.
[0024] In this embodiment, Figure 2 and Figure 3As shown, the anti-bypass iron sheet 4 and the wire brush 5 together constitute an anti-bypass mechanism; it should be noted that during the pouring of the ground-connected wall, due to the influence of soil pressure, the anti-bypass iron sheet 4 will not be close to the groove wall, so that along with the pouring of concrete, concrete will cause bypass, so in the utility model, a wire brush 5 is provided on the inner side opposite to the anti-bypass iron sheet 4. In actual use, the anti-bypass iron sheet 4 is tightly attached to the surface of the groove width wall 6 through the wire brush 5, which can prevent the concrete from bypassing from the edge of the I-beam joint during the pouring process, ensuring that the concrete can evenly fill the entire joint area, avoiding the generation of voids or uneven concrete distribution, and avoiding structural safety hazards. In addition, through the provision of the wire brush 5, larger impurities and bubbles can be filtered out during the concrete pouring process, thereby improving the density and uniformity of the concrete, thereby improving the construction quality of the entire structure. At the same time, the combination of the wire brush 5 and the anti-bypass iron sheet 4 can ensure good bonding between the concrete and the I-beam joint, thereby enhancing the integrity and durability of the structure.
[0025] In this embodiment, Figure 2 and Figure 3 As shown, the surface of the wire brush 5 is coated with grease; it should be noted that in the utility model, a wire brush 5 is provided on the inner side opposite to the anti-bypass iron sheet 4, and grease is evenly coated on the surface of the wire brush 5. In actual use, the grease can reduce the friction between the wire brush 5 and the concrete, making it easier for the concrete to pass through, and avoiding the blockage of the concrete at the wire brush 5. At the same time, the grease can provide a protective film for the wire brush 5 to prevent it from rusting in a humid environment and prolong the service life of the wire brush 5. The lubricating effect of the grease helps the wire brush 5 to stay clean during the work process and reduce the concrete residue, so that the wire brush 5 can continue to work effectively. At the same time, by reducing the blockage and adhesion of the concrete, the grease can ensure the smooth operation of the wire brush 5 and improve the efficiency of concrete pouring. In addition, the grease can also help to prevent the concrete residue on the wire brush 5 from drying out, thereby preventing the concrete quality from being damaged and improving the structural integrity and integrity.
[0026] In this embodiment, Figure 2 and Figure 3As shown, the length of the wire brush 5 is longer than the length of the anti-bypass iron sheet 4; it should be noted that in the utility model, the length of the wire brush 5 is set to exceed the length of the anti-bypass iron sheet 4, so that during use, the wire brush 5 can cover and exceed the edge of the anti-bypass iron sheet 4, thereby providing a better sealing effect, helping to prevent concrete from circumventing the edge of the anti-bypass iron sheet 4 during pouring, ensuring that the concrete can be evenly and fully filled into the entire groove of the I-beam joint, and through the extension of the wire brush 5, the concrete flow can be more effectively intercepted and dispersed, reducing the possibility of concrete circumference, thereby ensuring the integrity of the structure and the uniformity of the concrete, helping to improve the stability of the entire structure, and reducing structural problems caused by uneven distribution of concrete. At the same time, the longer design of the wire brush 5 helps to avoid blockage of concrete at the edge of the anti-bypass iron sheet 4, ensuring that the concrete can pass smoothly, and avoiding the formation of voids or defects at the joint.
[0027] In this embodiment, Figure 2 and Figure 3 As shown, the arrangement direction of the steel wires of the wire brush 5 is opposite to the direction of the starting point of concrete flow; it should be noted that in the utility model, when the steel wire brush 5 is arranged on the relatively inner side of the anti-bypass iron sheet 4, it is necessary to pay attention to setting the arrangement direction of its steel wires to be opposite to the direction of the starting point of concrete pouring flow. In this way, in actual use, the steel wire brush 5 can effectively block the flow of concrete along the original direction, and at the same time guide the concrete to flow in the opposite direction, ensuring that the concrete can evenly fill the joint area, reducing the generation of voids and loose areas, and then by ensuring the uniform distribution and good density of concrete at the joint, it is helpful to enhance the overall safety and durability of the structure, reduce structural hazards caused by construction defects, and at the same time, through the blocking effect of the steel wire brush 5, it can prevent the concrete from bypassing at the I-beam joint, reduce concrete defects caused by bypassing, and the combing effect of the steel wire brush 5 also helps to remove bubbles in the concrete, improve the density of the concrete and the strength of the overall structure.
[0028] The use method and advantages of the utility model: When the rigidity-enhanced anti-bypass I-beam joint is used, the working process is as follows:
[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, firstly, in order to enhance the rigidity of the I-beam joint and strengthen its anti-circumvention effect, in the present invention, the left wing plate 1 and the right wing plate 3 are provided with oblique tie bars 7 in contact with the web 2, and at the same time, the cross-sections of the wing plates and the web 2 close to the pit are thickened, thereby enhancing the overall rigidity of the entire I-beam joint, wherein the oblique tie bars 7 can provide additional rigidity and stability in the structure, ensuring that the I-beam will not deform when bearing loads, and enhancing the cross-sectional thickness of the left wing plate 1 and the web 2 can significantly improve the rigidity and bearing capacity of the I-beam joint, providing it with Stronger bending and shearing resistance helps to reduce stress concentration, thereby improving the fatigue resistance of the structure and extending the service life of the I-beam. At the same time, the anti-bypass iron sheet 4 tightly attached to the trough auxiliary wall 6 can ensure that the concrete will not bypass the I-beam joint and guide the concrete to flow into the correct area. The wire brush 5 follows closely to further ensure the uniform distribution of the concrete. At the same time, the grease coated on its surface reduces adhesion and protects the wire brush 5. The wall 6 serves as the final physical barrier to ensure that the concrete is evenly filled at the joint, enhancing the overall performance of the structure.
