Description

Technical Field

[0001] This application relates to the field of angle steel reinforcement technology, for example to a reinforcement structure for the main material of an angle steel tower. Background Technology

[0002] The descriptions in this section are provided only as background information relating to this disclosure and do not constitute prior art.

[0003] With the continuous upgrading of power infrastructure, angle steel towers need to support a large number of new equipment, and the loads of some equipment have exceeded the original design capacity of the towers. Furthermore, long-term exposure to harsh natural environments (such as wind and rain erosion and extreme weather) has caused surface damage or material performance degradation in the main materials of the angle steel towers, reducing their actual load-bearing capacity and wind resistance, posing structural safety hazards. To ensure the reliability of the power transmission system, it is urgent to repair and reinforce the angle steel towers.

[0004] In current angle steel tower reinforcement technology, a common approach is to attach a reinforcing plate to the surface of the main angle steel member and fasten it with bolts. However, this approach has significant drawbacks: the reinforcing plate and the main angle steel member are only locally fixed through discrete bolt nodes, failing to form a continuous and uniform force transmission interface; the load is concentrated at the bolt connection, easily causing stress concentration around the hole, leading to deformation or even cracking of the bolt hole; physical gaps exist between the reinforcing plate and the main angle steel member in non-connected areas, preventing them from working together as a whole structure to share the load, significantly weakening the reinforcement effect; and the separate connection is insufficient to effectively suppress local buckling or deformation of the main angle steel member. Utility Model Content

[0005] This application provides a reinforcement structure for the main member of an angle steel tower. By setting an adhesive injection groove and an adhesive injection hole on the bonding surface of the reinforcement plate, a continuous and uniform adhesive layer is formed after the adhesive is injected. This enables the full-interface bonding force transfer between the reinforcement plate and the main member of the angle steel, avoiding the local stress concentration problem caused by traditional bolt connections and effectively reducing the risk of deformation or cracking around the holes. The adhesive layer fills the physical gap between the reinforcement plate and the main member of the angle steel, making them a composite integral structure that shares the load, inhibits local buckling or deformation of the main member of the angle steel, and improves wind pressure resistance and bending resistance. Combining adhesive injection bonding with bolt connection (through connection holes) forms a composite reinforcement mechanism of "adhesive bonding + mechanical fastening," which not only ensures long-term bonding stability but also provides redundant load-bearing paths, enhancing structural reliability.

[0006] A reinforcement structure for the main member of an angle steel tower, comprising: a reinforcement plate fitted to the main member of the angle steel, characterized in that the reinforcement plate comprises:

[0007] The bonding surface is bonded to the inner or outer side of the main angle steel material;

[0008] An adhesive injection groove is provided on the bonding surface along the length of the reinforcing plate;

[0009] Multiple glue-filling holes are spaced apart on the reinforcing plate and are connected to the glue-filling tank and the outside.

[0010] Multiple connection holes are spaced apart on the reinforcing plate, located on one side of the glue-filling groove.

[0011] By setting glue-filling grooves and holes on the bonding surface of the reinforcing plate, a continuous and uniform adhesive layer is formed after the adhesive is injected. This allows for full-interface bonding force transfer between the reinforcing plate and the main angle steel member, avoiding the local stress concentration problem caused by traditional bolt connections and effectively reducing the risk of deformation or cracking around the holes. The adhesive layer fills the physical gap between the reinforcing plate and the main angle steel member, forming a composite integral structure that shares the load, inhibits local buckling or deformation of the main angle steel member, and improves wind pressure and bending resistance. Combining glue-filling bonding with bolt connections (through connection holes) forms a composite reinforcement mechanism of "adhesive bonding + mechanical fastening," which ensures long-term bonding stability and provides redundant load-bearing paths, enhancing structural reliability.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0035] Combination Figure 1-5 As shown in the figure, this disclosure provides a reinforcement structure for the main member of an angle steel tower, including: a reinforcement plate 11 that is attached to the main member of the angle steel 16, characterized in that the reinforcement plate 11 includes:

[0036] The bonding surface 111 is bonded to the inner or outer side of the angle steel main material 16;

[0037] An adhesive injection groove 112 is provided on the bonding surface 111 along the length of the reinforcing plate 11;

[0038] Multiple glue-filling holes 113 are spaced apart on the reinforcing plate 11 and communicate with the glue-filling tank 112 and the outside; the glue can be structural glue and is applied with a glue gun.

[0039] Multiple connecting holes 114 are spaced apart on the reinforcing plate 11, located on one side of the glue-filling groove 112. The connecting holes 114 are connected to the angle steel main member 16 by bolts, and the connecting holes 114 can be elongated holes.

[0040] The reinforcing plate 11 is a long strip plate, and the material is not limited. It can be cut according to actual needs. Its width and thickness are determined by the main angle steel material 16. For larger and thicker angle steel, a stronger reinforcing plate 11 can be selected.

[0041] The glue-filling groove 112 can be a concave groove formed by bending the reinforcing plate 11. When filling the glue, the ends of the glue-filling groove 112 can be sealed with plugs of corresponding size, or materials such as wood, stone, paper scraps, and plastic film on site can be used for sealing according to the site conditions.

[0042] The glue-filling hole 113 is a through hole opened in the concave groove area. Multiple glue-filling holes 113 are provided to facilitate cutting into multiple sections for use. Each section has a hole. If the glue-filling groove 112 of a certain section is blocked, other glue-filling holes 113 on that section can be used.

[0043] By setting an adhesive injection groove 112 and an adhesive injection hole 113 on the bonding surface 111 of the reinforcing plate 11, a continuous and uniform adhesive layer is formed after the adhesive is injected. This enables the reinforcing plate 11 and the main angle steel member 16 to achieve full-interface bonding force transfer, avoiding the local stress concentration problem caused by traditional bolt connections and effectively reducing the risk of deformation or cracking around the hole. The adhesive layer fills the physical gap between the reinforcing plate 11 and the main angle steel member 16, making them form a composite integral structure that jointly bears the load, inhibits local buckling or deformation of the main angle steel member 16, and improves wind pressure resistance and bending resistance. Combining adhesive injection bonding with bolt connection (through connection hole 114) forms a composite reinforcement mechanism of "adhesive bonding + mechanical fastening", which not only ensures long-term bonding stability but also provides redundant load-bearing paths, enhancing structural reliability.

[0044] In some embodiments, the angle steel tower main material reinforcement structure further includes:

[0045] A sealing plug 12 is provided on the glue-filling hole 113.

[0046] In some embodiments, the connecting hole 114 is provided on the center line of the reinforcing plate 11, and the glue-filling groove 112 is provided in two places and is respectively provided on both sides of the connecting hole 114.

[0047] In some embodiments, one side of the reinforcing plate 11 is connected to the positioning plate 13, the positioning plate 13 is perpendicular to the reinforcing plate 11, and the reinforcing plate 11 is positioned in contact with the edge of the angle steel main member 16. The positioning plate 13 assists in positioning to ensure that the reinforcing plate 11 moves to the required position.

[0048] In some embodiments, one side of the positioning plate 13 is connected to the buckle plate 14, and the inner side of the buckle plate 14 cooperates with the mating surface 111 to clamp the angle steel main member 16. The buckle plate 14 assists in fixing the reinforcing plate 11 to the angle steel main member 16, which facilitates the installation of the reinforcing plate 11. Of course, this fixing is not firm and requires the connection hole 114 and bolts to lock it in place.

[0049] In some embodiments, two reinforcing plates 11 are provided and are respectively connected to two surfaces at the inside corner of the angle steel main member 16, and the two reinforcing plates 11 are connected by corner brackets 15. Corner brackets 15 are commonly used connectors for connecting aluminum profiles, and the corner brackets 15 in this application are similar. Corner brackets 15 significantly improve the torsional resistance of the angle steel main member 16.

[0050] In some embodiments, the corner bracket 15 is connected to the reinforcing plate 11 and the angle steel main member 16.

[0051] In some embodiments, the reinforcing plate 11, the positioning plate 13, and the buckle plate 14 are integrally bent and formed.
