Technical Field
[0001] This utility model relates to the field of steel structure reinforcement devices, specifically a steel structure beam-column joint reinforcement device with adjustable stress distribution. Background Technology
[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are mainly composed of components such as beams, steel columns, and steel trusses made of steel sections and plates. Beam-column joints are the most important joints in steel structures, as they directly affect the construction speed and the degree of prefabrication. Steel structure connections commonly use welded connections, bolted connections, or other methods.
[0003] For the reinforcement of welded steel structure joints, the most common method is to increase the cross-section of the steel structure through welding. However, this method involves a large amount of welding work, and the residual stress is difficult to estimate. Another method is to reinforce the joints by encasing them in concrete. This method can also improve the corrosion and fire resistance of the steel structure. However, directly encasing the joints in concrete requires the construction of a cast-in-place frame, which is inconvenient to install and disassemble, and makes it difficult to target areas prone to stress deformation, leading to resource waste. Therefore, those skilled in the art have provided a steel structure beam-column joint reinforcement device with adjustable stress distribution to solve the problems mentioned in the background art. Utility Model Content

The reinforcement components are used in pairs, each a two-piece L-shaped angle iron structure composed of two steel plates. The two steel plates have symmetrically arranged multi-row connecting through holes in two columns. A column and a horizontal beam are connected to the two steel plates respectively via bolts and nuts. The column and horizontal beam are welded together. Triangular reinforcing ribs are welded to the corners of the reinforcement components. The width of the two steel plates constituting the reinforcement component is greater than that of the column. The flange width of the crossbeam, and each of the connecting through holes is provided with a connecting threaded hole on the outer side. The connecting threaded hole on the installed reinforcing member is located on the outer side of the crossbeam. A casting plate is slidably connected between the two reinforcing members. The casting plate is provided with multiple installation grooves. Two casting limit plates are slidably connected in the installation grooves. The casting limit plates are set according to the positions where stress deformation is likely to occur. A connecting long bolt is provided in the connecting threaded hole between the two casting limit plates on the lower reinforcing member.
[0006] As a further embodiment of this utility model: a connecting pipe is provided on the crossbeam between the bolt tails of the two casting limiting plates for connecting the upper and lower reinforcing components, and the top and bottom of the connecting pipe are fitted with nuts for fixing.

[0008] As a further improvement of this utility model: the installation groove located between the two casting limiting plates is provided with sealing blocks, and the sealing blocks are slidably connected to the installation groove.
[0009] As a further improvement of this utility model: a handle is welded to the center of the back of the pouring horizontal plate; when using the pouring horizontal plate and the pouring limiting plate for concrete pouring reinforcement, a thin film is applied to the inner side of the pouring horizontal plate and the inner side of the pouring limiting plate.
[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by setting a casting horizontal plate between two reinforcing components, the position of the casting limiting plate can be flexibly selected for the position on the beam at the node that needs to resist stress reinforcement, thus preventing resource waste.

The connecting threaded hole above the connecting long bolt serves as a casting hole and a vent hole, which is convenient to use.
[0011] 2. In this utility model, by installing a connecting pipe on the bolt for which concrete is to be poured, the connecting pipe can strengthen the concrete structure during the concrete pouring process. In addition, the connecting pipe protects the bolt tail located inside the concrete, preventing the concrete from completely fixing the bolt, and making it easy to disassemble during the dismantling operation.

A column 1 and a horizontal beam 2 are connected to the two steel plates of the reinforcement component 3 respectively by bolts and nuts. The column 1 and the horizontal beam 2 are welded together. Triangular reinforcing ribs 4 are welded to the corners of the reinforcement component 3. The width of the two steel plates constituting the reinforcement component 3 is greater than the flange width of the column 1 and the horizontal beam 2. A connecting threaded hole 10 is provided on the outer side of each connecting through hole 9. After installation... The threaded holes 10 on the reinforcing member 3 are located on the outer side of the crossbeam 2. A casting cross plate 5 is slidably connected between the two reinforcing members 3. The casting cross plate 5 is provided with multiple installation grooves 11. Two casting limiting plates 6 are slidably connected in the installation grooves 11. The casting limiting plates 6 are set according to the positions where stress deformation is likely to occur. A connecting long bolt 8 is provided in the threaded holes 10 between the two casting limiting plates 6 on the reinforcing member 3 below. The connecting long bolt 8 can increase the strength of the concrete and strengthen the position against stress as needed. The installation grooves 11 can be used to flexibly change the installation position of the casting limiting plates 6, and concrete pouring can be carried out in a targeted manner to improve the structural strength of the crossbeam 2. It is convenient to use and saves resources.
[0016] Among them, a connecting pipe 7 is provided on the crossbeam 2 between the two casting limit plates 6 and between the bolt tails of the upper and lower reinforcing components 3. The top and bottom of the connecting pipe 7 are fitted with the fixing nut. The connecting pipe 7 acts as a steel bar in the concrete to improve the concrete strength and also protects the bolt from being completely fixed by the concrete, making it easy to disassemble. The top of the casting limiting plate 6 is provided with an installation slider 14, which is slidably connected to the installation groove 11. The casting limiting plate 6 is slidably connected to the upper and lower reinforcing components 3.

Among them, the installation groove 11 located between the two pouring limit plates 6 is equipped with sealing blocks 12. The sealing blocks 12 are slidably connected to the installation groove 11 to protect the installation groove 11 from concrete entering during the pouring process and to facilitate cleaning. The back center of the casting horizontal plate 5 is welded with a handle 13. When using the casting horizontal plate 5 and the casting limiting plate 6 for concrete pouring reinforcement, a film is placed on the inner side of the casting horizontal plate 5 and the inner side of the casting limiting plate 6 to facilitate demolding of the casting horizontal plate 5 and make it convenient to use.

A sealing protrusion 15 is installed in the installation groove 11 between the two pouring limiting plates 6. The inner side of the crossbeam 5 is poured on the inner side of the pouring limiting plate 6. A thin film is pasted on to facilitate demolding. The casting limiting plate 6 is slidably connected to the upper and lower reinforcing components 3, so that the top of the sealing protrusion 15 on the top of the casting limiting plate 6 is in contact with the web plate on the crossbeam 2.

Concrete is poured through the connecting threaded hole 10 on the top of the connecting bolt 8. The concrete is poured in a targeted manner at the location where stress deformation occurs. While ensuring the reinforcement capacity, it can save resources and is easy to use. After the concrete has completely solidified, the handle 13 on the casting cross plate 5 is pulled to demold the casting cross plate 5 and the casting limiting plate 6. It can be reused.
