Description

Technical Field

[0001] This utility model belongs to the field of prefabricated building technology, specifically relating to a steel structural component and a prefabricated structure. Background Technology

[0002] Steel components, or steel structural components, are widely used in the construction industry due to their advantages such as light weight, high strength, quick installation, and good seismic performance. With the development of prefabricated structures, prefabricated walls, columns, and beams are also widely used in the construction field. When installing and using prefabricated structures, steel structural components are often used for connection and reinforcement to improve the connection strength between the prefabricated structure and other structural components.

[0003] In related prior art, such as Chinese Patent No. CN222375639U, a steel structural component and prefabricated structure are disclosed, including a male connector and a female connector. The male connector includes a first male connector plate and a second male connector plate, and the female connector includes a first female connector plate and a second female connector plate. The second male connector plate is flush with both ends of the second female connector plate and is fixedly attached to the surface of the second female connector plate. The first male connector plate is perpendicular to the second male connector plate, and the first female connector plate is perpendicular to the second female connector plate. The surfaces of the first male connector plate and the first female connector plate are fixedly attached to form a first contact surface, which is located at the center of the width of the second male connector plate. A number of reinforcing ribs are respectively and spaced apart on the second male connector plate and the second female connector plate. By embedding the male connector and the female connector in the frame column and the frame beam respectively, the connection between the frame column and the frame beam can be quickly realized without the need to connect each reinforcing bar individually, thus improving the connection efficiency.

[0004] However, in actual use, after the first connecting male plate and the first connecting female plate abut together, the connecting male plate does not have the function of limiting the position of the connecting female plate. That is, the first connecting male plate cannot limit the position of the first connecting female plate. As a result, workers still need to stabilize the position of the beam. Otherwise, the movement or shaking of the frame beam will cause the first connecting female plate to detach from the first connecting male plate. This makes it difficult for workers to connect the first connecting male plate and the first connecting female plate with bolts. The method of workers stabilizing the position of the frame beam while installing bolts is labor-intensive and not conducive to actual use. Utility Model Content

[0005] The present invention aims to provide a steel structural component and a prefabricated structure to solve the problem of the high manpower consumption during the installation and use of the existing structures mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel structural component, comprising...

[0007] The connecting component includes a side plate and a T-shaped steel strip. The T-shaped steel strip is fixed to the side wall of the side plate, and the vertical end of the T-shaped steel strip is located above the horizontal end of the T-shaped steel strip.

[0008] The connecting mother component includes two channel steel bars symmetrically distributed about the T-shaped steel bar. The slots of the two channel steel bars are arranged opposite each other. The channel steel bars abut against the side wall of the vertical end of the T-shaped steel bar and the top surface of the horizontal end of the T-shaped steel bar, respectively. A connecting plate is fixed inside the two channel steel bars on the side away from the side plate.

[0009] Connecting components are used to connect channel steel bars to T-shaped steel bars.

[0010] The present invention is further configured such that: the connecting assembly includes a connecting bolt and a connecting nut, the ends of the connecting bolt are slidably inserted into the T-shaped steel bar and the channel steel bar respectively, the connecting nut is threadedly fitted onto the connecting bolt, and the head of the connecting bolt and the connecting nut respectively abut against the two channel steel bars on both sides.

[0011] The present invention is further configured such that: a rib is fixed at the bottom of the side plate, and the rib abuts against the bottom surface of the horizontal end of the T-shaped steel strip.

[0012] This utility model also provides a prefabricated structure, including

[0013] An anchor plate is fixed to the side of the column away from the T-shaped steel bar, and the anchor plate is embedded in the column body;

[0014] The channel steel bars are embedded and fixed inside the beam body on the side away from the side plate;

[0015] The present invention is further configured such that the anchor plate has anchor holes.

[0016] The present invention is further configured such that: a partition is fixed inside the groove of the channel steel bar, and the partition is located inside the beam.

[0017] The present invention is further configured to include a connecting sleeve, wherein a first reinforcing rib is embedded and fixed in the column body, and a second reinforcing rib is embedded and fixed in the beam body, the end of the first reinforcing rib is connected to the end of the second reinforcing rib, and the connecting sleeve is respectively fitted onto the first reinforcing rib and the second reinforcing rib.

[0018] The present invention is further configured such that: a reserved hole is provided on the side plate, an installation seat is fixed on the outer wall of the channel steel strip, the first reinforcing rib is adapted to the reserved hole, the second reinforcing rib is slidably inserted into the installation seat, and the installation seat is located inside the beam.

[0019] The above-described solution of this utility model has at least the following beneficial effects:

[0020] In this application, by setting two channel steel bars and T-shaped steel bars, after the channel steel bars are fitted onto the T-shaped steel bars, the channel steel bars can be prevented from descending due to the abutment of the horizontal end of the T-shaped steel bars, and the vertical ends of the T-shaped steel bars restrict the relative movement of the two channel steel bars respectively. Thus, the channel steel bars can only move upward or away from the side plate. At the same time, under the action of their own weight, the channel steel bars cannot move upward. Channel steel bars are set on both sides of the beam. Under the premise that the channel steel bars on both sides are adapted to the T-shaped steel bars of the columns on both sides respectively, the channel steel bars cannot move away from the side plate. That is, the beam cannot move horizontally or vertically (it can only jump upward under the condition of large vibration). Therefore, during installation and use, after the workers have positioned the beam (that is, after the channel steel bars are fitted onto both sides of the T-shaped steel bars), no additional manpower is needed to stabilize the position of the beam before the connecting components can be used to connect the male and female connecting parts. The installation saves manpower and is simple and convenient to operate.

[0034] Example:

[0035] As attached Figure 1-4 As shown, this utility model discloses a steel structural component and a prefabricated structure, specifically including a steel structure and a prefabricated structure. The steel structural component includes a male connector, a female connector, and a connecting assembly. The prefabricated structure includes a column 410, a beam 510, a connecting sleeve 610, a first reinforcing rib 620, and a second reinforcing rib 630. The male connector includes a side plate 110 and a T-shaped steel bar 120. The T-shaped steel bar 120 is fixed to the side wall of the side plate 110, and the vertical end 121 of the T-shaped steel bar 120 is located above the horizontal end 122 of the T-shaped steel bar 120. Multiple anchor plates 420 are fixed on the side of the side plate 110 away from the T-shaped steel bar 120, and the anchor plates 420 have anchor holes 421. Anchor plate 420 is embedded and fixed inside column 410. The anchor plate 420 allows side plate 110 to be pre-installed during the casting of column 410, thus pre-setting side plate 110 onto column 410, avoiding subsequent welding and providing greater stability. Anchor holes 421 allow the anchor plate 420 to be connected to column 410 via reinforcing bars, and the reinforcing bars further restrict the connection between anchor plate 420 and column 410, making the connection more robust. Ribs 130 are fixed to the bottom of side plate 110, and ribs 130 abut against the bottom surface of the horizontal end 122 of T-shaped steel bar 120. Ribs 130 can enhance the bearing capacity of T-shaped steel bars 120. Pre-drilled holes 111 are provided on the side plate 110. The pre-drilled holes 111 allow the position of the first reinforcing rib 620 to be positioned through the side plate 110. Thus, when the column 410 is poured, one end of the first reinforcing rib 620 can be anchored and fixed, so that workers do not need to perform special positioning of the first reinforcing rib 620. This makes it more convenient and faster for the first reinforcing rib 620 and the column 410 to be precast and cast as a whole.

[0036] The connecting component includes two channel steel bars 210 symmetrically distributed about the T-shaped steel bar 120. The slots of the two channel steel bars 210 are arranged opposite to each other. The channel steel bars 210 abut against the side wall of the vertical end 121 and the top surface of the horizontal end 122 of the T-shaped steel bar 120, respectively. A connecting plate 220 is fixed inside the two channel steel bars 210 on the side away from the side plate 110. A partition plate 520 is fixed inside the slot of the channel steel bar 210, and an installation plate is fixed on the outer wall of the channel steel bar 210. The mounting base 530, via the connecting plate 220, welds and fixes the two channel steel bars 210, thus fixing their relative positions. This process is simple and convenient. The side of the channel steel bar 210 away from the side plate 110 is embedded and fixed inside the beam body 510. The partition plate 520 is located inside the beam body 510. The partition plate 520 increases the contact area between the channel steel bar 210 and the reinforced concrete structure of the beam body 510, thereby strengthening the connection strength between the channel steel bar 210 and the beam body 510. Furthermore, the mounting base 530 allows the second reinforcing rib 630 to be precast and cast along with the beam body 510 without requiring special positioning by workers, making the precasting of the second reinforcing rib 630 and the beam body 510 more convenient and faster. The mounting base 530 also increases the contact area between the channel steel bar 210 and the internal reinforced concrete structure of the beam body 510, thereby improving the connection strength between the channel steel bar 210 and the beam body 510.

[0037] The first reinforcing rib 620 and the second reinforcing rib 630 are positioned by the reserved hole 111 and the mounting base 530 respectively, so that when the beam 510 and the column 410 are installed, the end of the first reinforcing rib 620 can be aligned with the second reinforcing rib 630. During installation, the connecting sleeve 610 is first installed on the second reinforcing rib 630. After the ends of the first reinforcing rib 620 and the second reinforcing rib 630 are aligned, the first reinforcing rib 620 and the second reinforcing rib 630 are connected by welding. Then, the connecting sleeve 610 is slid onto the first reinforcing rib 620 and the second reinforcing rib 630, and then the connecting sleeve 610 is welded to connect and fix the first reinforcing rib 620 and the second reinforcing rib 630.

[0038] In this design, when the channel steel bar 210 is fitted onto the T-shaped steel bar 120, the upper first reinforcing rib 620 is bent (the first reinforcing rib 620 is bent during the prefabrication of the beam 510) to allow space for the channel steel bar 210. After the channel steel bar 210 is installed and positioned, the first reinforcing rib 620 is bent into a straight rod shape to align with the second reinforcing rib 630. In this design, one side wall of the column 410 has four first reinforcing ribs 620, and one side wall of the beam 510 has four second reinforcing ribs 630. Similarly, the second reinforcing bar 630 located below the channel steel bar 210 on the beam 510 may be bent before installation to allow space for installation, and after installation, the second reinforcing bar 630 is restored to connect with the first reinforcing bar 620.

[0039] Multiple connecting components are provided, including connecting bolts 310 and connecting nuts 320. The ends of the connecting bolts 310 are slidably inserted into the T-shaped steel strip 120 and the channel steel strip 210, respectively. The connecting nuts 320 are threaded onto the connecting bolts 310, and the heads of the connecting bolts 310 and the connecting nuts 320 abut against the two channel steel strips 210 on both sides. Half of the connecting components has its head located on one side of the T-shaped steel strip 120, while the other half has its head located on the other side.
