DETAILED DESCRIPTION
[0034] The following is combined with Figure 1 This application is described in further detail.
[0035] The embodiment of the present application discloses an assembled building frame structure.
[0036] refer to Figure 1The assembled building frame structure includes a top frame 1, a bottom frame 2, columns 3 and a roof frame 4. The top frame 1 and the bottom frame 2 are both assembled by four square steels. The columns 3 are arranged vertically and installed at the four corners of the lower surface of the top frame 1. The bottom end is installed at the four corners of the upper surface of the bottom frame 2. The columns 3 are also located in the middle of the frame of the top frame 1 and the bottom frame 2 for support. The columns 3 are also square steel. The roof frame 4 is installed on the top frame 1 and is a load-bearing support structure for the roof. The two longer square steel side walls of the top frame 1 and the bottom frame 2 are installed with a first horizontal plate 11, and the first horizontal plates 11 have the same spacing. A second horizontal plate 31 is installed in the middle and upper position between the columns 3, and the distance between the second horizontal plate 31 and the bottom frame 2 is not less than 2m. A third horizontal plate 12 is installed between the first horizontal plates 11 and between the first horizontal plate 11 and the top frame 1 and the bottom frame 2. The third horizontal plate 12 is located in the middle of the second horizontal plate 31. A door post 35 is fixed on the lower surface of the second transverse plate 31, and a door hole 36 for installing a door is formed between the door post 35 and the upright column 3. A fourth transverse plate 32 is installed below the second transverse plate 31, and a window post 33 is installed between the fourth transverse plate 32 and the second transverse plate 31, and a window hole 34 is formed between the window post 33, the second transverse plate 31 and the fourth transverse plate 32. The first transverse plate 11, the second transverse plate 31, the third transverse plate 12, the fourth transverse plate 32, the door post 35 and the bed post are all square steel.
[0037] In the assembled building frame of this embodiment (except the four corners of the door opening 36, the window opening 34 and the roof frame 4), the right-angled ribs 5 are installed at the ends of the square steel and the right-angled connections formed by the other square steels. That is, the four corners of the door opening 36 and the window opening 34 do not contain the right-angled ribs 5, and the roof frame 4 does not contain the right-angled ribs 5. The right-angled ribs 5 are "L"-shaped, and a triangular reinforcing rib 51 is fixed in the middle. Both ends of the right-angled ribs 5 are penetrated by bolts and penetrate the corresponding square steel and are threadedly connected with nuts. If there is no right-angled rib 5 at the corresponding position on the other side of the square steel after the bolt passes through the square steel, a pad 6 is placed, and the bolt passes through the pad 6 and is threadedly connected with the nut. If there is a right-angled rib 5 at the corresponding position on the other side of the square steel, it passes through the right-angled rib 5 and is threadedly connected with the nut. The pad 6 is also located at both ends of the third horizontal plate 12 and at both ends of the second horizontal plate 31. The hardness of the pad 6 material is lower than that of the right-angled rib 5, and this embodiment is an inorganic non-metallic material.
[0038] The main structure formed by the top frame 1 and the bottom frame 2 is connected by the column 3, and is connected and reinforced by the first horizontal plate 11, the second horizontal plate 31 and the third horizontal plate 12, thereby forming the main frame structure of the assembled building. The overall weight is reduced by using square steel materials. The square steel is combined and connected and installed by connecting the right-angle rib plate 5, and at the same time, at least the right-angle rib plate 5 or the pad 6 is combined and installed on the other side of the square steel installed by the right-angle rib plate 5, which effectively improves the strength of the connection. The position setting of the pad 6 effectively improves the seismic resistance of the overall frame structure and reduces the sound transmission of the metal frame structure. The connection of the frame structure adopts a non-welding installation, which further improves the seismic resistance of the frame structure. The height setting of the second horizontal plate 31 provides space for the installation of the door opening 36 and the window opening 34, and at the same time, the structural strength of the door opening 36 and the window opening 34 is improved by the frame structure, thereby improving the firmness of the doors and windows after installation.
[0039] refer to Figure 1 The roof frame 4 includes a top column 41, a top beam 42 and an inclined plate 43. The top column 41 is installed on the upper surface of the second horizontal plate 31 and the upper surface of the two shorter square steels of the top frame 1. The top beam 42 is installed at the top of the top column 41. The inclined beam is installed on both sides of the top beam 42 and is tilted downward, and the lower surface of the inclined beam abuts against the top beam 42. The position of the inclined beam is opposite to the top column 41. The top beam 42, the top column 41 and the inclined plate 43 are all square steels. The right-angle rib plate 5 is installed at the right angle formed by the top column 41 and the third horizontal plate 12, and is also installed at the right angle connection formed by the top column 41 and the top beam 42. A "V"-shaped angle rib plate 7 is installed at the angle formed by the top column 41 and the inclined plate 43, and the angle rib plate 7 is threadedly connected to the nut after passing the corresponding square steel by bolts. The angle rib plate 7 is also installed between the lower surface of the inclined plate 43 and the circumferential outer wall of the top frame 1.
[0040] The position setting of the top column 41 can effectively stably intercept the third horizontal plate 12 and the top beam 42 through the right-angle rib plate 5, and at the same time, it also makes room for the installation of the angle rib plate 7, and improves the installation strength of the inclined plate 43 through the installation of the angle rib plate 7. Not only does it improve the strength and earthquake resistance of the roof frame 4, but it also effectively improves the connection strength and stability of the roof frame 4 and the top frame 1.
[0041] The implementation principle of an assembled building frame structure in the embodiment of the present application is as follows: the top frame 1 and the bottom frame 2 are connected by columns 3, and the formed frame structure is reinforced by the first horizontal plate 11, the second horizontal plate 31 and the third horizontal plate 12. The overall frame is made of square steel material to ensure strength while reducing weight. The overall structural connection method uses right-angle ribs 5 and angle ribs 7 for non-welding connection. While improving the connection strength, the pad 6 effectively improves the seismic resistance of the overall frame structure, and effectively reduces the sound transmission of the metal frame structure, thereby improving the connection strength, safety and seismic resistance of the frame structure under the premise of the integrity of the assembled building frame. The square steel structure and the connection structure are standardized, which is more convenient for engineering prefabrication production and rapid on-site installation.
[0042] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
