Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a fixed structure for steel beams and concrete beams. Background Technology

[0002] In building structures, the fixing of steel beams and concrete beams is a key link to ensure the stability and safety of the overall structure. Good fixing can effectively transfer loads and enable the two different materials to work together. For example, in multi-story buildings or industrial plants, the connection nodes between steel beams and concrete beams need to withstand the gravity loads from the superstructure, horizontal wind loads, or shear forces and bending moments generated by earthquakes. If the fixing is not firm, it may lead to node failure, which in turn affects the safety of the entire building structure.

[0003] In building structures, after steel beams are connected to concrete beams, the steel beams undergo deformation due to long-term loads or temperature changes. This can lead to loosening and cracks at the connection. Furthermore, controlling the prestressed spacing to accommodate prestressed deformation requires repeated measurements of the four corners, a cumbersome process. Therefore, a fixed structure for steel beams and concrete beams is needed. This structure, with its rapid prestressed spacing control component, can adapt to the different requirements of various projects for prestressed deformation, reducing errors and adjustment time during construction, improving construction efficiency. Simultaneously, a reasonable prestressed spacing can effectively extend the service life of the building structure and reduce maintenance costs. Utility Model Content

Detailed Implementation

[0022] In the following description, embodiments of the steel beam and concrete beam fixing structure of this utility model will be described with reference to the accompanying drawings.

[0023] Figure 1-4This invention illustrates a steel beam and concrete beam fixing structure according to an embodiment of the present invention, including a steel plate 1 attached to a wall. A steel beam 2 is provided on the right side of the steel plate 1, and multiple pre-embedded screws 3 are provided through the left side of the steel plate 1. The pre-embedded screws 3 are embedded inside the wall, and the right end of the pre-embedded screws 3 extends through to the right side of the steel plate 1 and is threadedly connected to two first nuts 4. A connecting assembly 5 is provided on the right side of the steel plate 1. The connecting assembly 5 includes a steel web 51 welded to the front and rear ends of the right side of the steel plate 1. Multiple limiting protrusions 7 are welded to the front side of the front steel web 51, and the surfaces of the limiting protrusions 7 are flush with the wall surface. The surfaces of the high-strength bolts 52 are tightly fitted together. The left end of the steel beam 2 is inserted between two steel webs 51. Multiple high-strength bolts 52 are installed through the front side of the front steel web 51. Anti-loosening washers 55 are fitted on both the front and rear sides of the surface of the high-strength bolts 52. The anti-loosening washers 55 are tightly pressed against the surface of the steel web 51. The anti-loosening washers 55 enhance the friction coefficient between the steel web 51, the second nut 54, and the steel web 51, thereby preventing the high-strength bolts 52 from loosening on their own after installation due to external forces. This improves the adhesion between the steel plate 1 and the steel structure. To ensure the stability of the beam 2 after connection, the surface of the steel web 51 is provided with multiple adjustable screw holes 53 that are compatible with the high-strength bolts 52. The rear end of the high-strength bolts 52 penetrates the steel beam 2 and extends to the back surface of the rear steel web 51. Two second nuts 54 are connected to the rear thread of the high-strength bolts 52. A distance control assembly 6 is provided on the right side of the steel plate 1. The distance control assembly 6 includes a limiting guide rail 61 fixedly connected to the front and rear ends of the right side of the steel plate 1. A slide 62 is slidably connected to the inner cavity of the limiting guide rail 61. Two abutments 63 are fixedly connected to the top and bottom of the right side of the slide 62. The bottom of the slide 62 is rotatably connected to an adjusting bolt 64, and the bottom end of the adjusting bolt 64 is fixedly connected to a hexagonal sleeve 8. A third nut 65 is welded to the bottom right side of the steel plate 1. The adjusting bolt 64 is threaded into the inner cavity of the third nut 65. Through the setting of the distance control component 6, the adjusting bolt 64 and the third nut 65 work together to raise and lower the slide 62, so that the stop block 63 can block the space between the steel plate 1 and the steel structure beam 2 when controlling the distance. After installation, the reserved space is left open, thus reserving the range for possible prestressed deformation during subsequent use.

[0024] Working principle: In use, the user welds and fixes the steel plate 1 and the steel web 51, then places the steel plate 1 on the surface of the pre-embedded screw 3, tightens the first nut 4, and installs and fixes the steel plate 1. The user then inserts the left end of the pre-embedded screw 3 into the inner cavity of the two steel webs 51. The user then rotates the adjusting bolt 64, which pushes upwards during rotation, allowing the slide 62 to drive the stop block 63 to its highest position. The high-strength bolt 52 passes through the adjustable screw hole 53 and the steel structure beam 2, and the second nut 54 is threaded onto the surface of the high-strength bolt 52. The second nut 54 is initially tightened, allowing the steel web 51 to... The high-strength bolt 52 is temporarily fixed, and then the steel structure beam 2 is pushed forward so that the left side of the steel structure beam 2 is in close contact with the right side of the abutment block 63, thus determining the prestressed reserved space. Then, the user rotates the adjusting bolt 64 in the opposite direction. During the rotation of the inner cavity of the third nut 65, the adjusting bolt 64 is displaced downward, so that the adjusting bolt 64 can drive the slide 62 to slide downward. During the downward movement of the slide 62, the abutment block 63 is displaced downward, so that the abutment block 63 is disengaged from the left side of the steel structure beam 2. At this time, the reserved space between the steel plate 1 and the steel structure beam 2 is exposed. Finally, the user retightens the second nut 54 to install and fix the steel structure beam 2.

[0025] In summary: This steel structure beam and concrete beam fixing structure uses the pre-embedded screw 3 and the first nut 4 to install and fix the steel plate 1. Then, the steel plate 1 and the steel structure beam 2 are connected and fixed by the setting of the connecting component 5. At the same time, the space control component 6 is set to reserve prestressed deformation space between the steel plate 1 and the steel structure beam 2, so as to achieve the purpose of reliable and stable connection and quick control of the reserved space.
