DETAILED DESCRIPTION

[0021] In order to make the objects, technical solutions and advantages of the present application clearer, the following will describe the present application through specific embodiments shown in the drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present application.

[0023] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] Example: Figures 1 to 5 As shown, a load-bearing frame structure of a high-altitude large-span atrium structure is mainly composed of a load-bearing platform 1, a diagonal brace 2, a diagonal brace beam 3, a tension support 4 and a diagonal brace support 5. It can be installed on the floor structure below the top of the atrium, that is, on the main structure 7. Then, an operating platform frame 11 is erected on the above-mentioned load-bearing platform 1 to construct the atrium structure. Compared with the prior art of erecting a higher scaffolding at the bottom of the atrium, the erection height of the load-bearing scaffolding is greatly reduced. At the same time, the material consumption of the scaffolding is reduced, which can effectively shorten the scaffolding erection period and improve the construction efficiency of the high-altitude large-span atrium structure. Specifically, the above-mentioned tension support 4 and the above-mentioned diagonal brace support 5 are both used to be pre-buried in the main structure 7. The above-mentioned tension support 4 is located above the above-mentioned load-bearing platform 1 and is connected and fixed to the above-mentioned load-bearing platform 1 through the above-mentioned diagonal brace beam 3. The above-mentioned diagonal brace support 5 is located below the above-mentioned load-bearing platform 1 and is connected and fixed to the above-mentioned load-bearing platform 1 through the above-mentioned diagonal brace beam 3. The main function of the tension support 4 is to transfer the tension from the load-bearing platform 1 to the main structure 7, and by being pre-buried in the main structure 7, the tension support 4 can enhance the overall stability of the structure, especially when it is subjected to a large tension. The diagonal brace support 5 can effectively enhance the lateral stiffness of the structure by providing oblique support, and prevent the overall load-bearing frame structure from being excessively deformed under the action of lateral force. The tension support 4 and the diagonal brace support 5 are pre-buried so that the tension support 4, the diagonal brace support 5 and the main structure 7 form a whole, so as to enhance the integrity and continuity of the structure, thereby ensuring the overall stability of the load-bearing frame structure and ensuring safety during construction. The pre-buried method can also reduce the complexity of the subsequent installation process, improve construction efficiency, and reduce construction risks.

[0025] The load-bearing platform 1 in this embodiment is mainly assembled by the platform main beam 1-1 and the platform secondary beam 1-2. The two ends of the platform main beam 1-1 are arranged on the main structure 7, and the platform secondary beam 1-2 is installed above the platform main beam 1-1. A plurality of platform secondary beams 1-2 are arranged at intervals along the length direction of the platform main beam 1-1. The platform main beam 1-1 is the main load-bearing component of the load-bearing platform 1, which is used to bear large loads and transfer the loads to the main structure 7. The two ends of the platform main beam 1-1 are arranged on the main structure 7, which plays a supporting and load transferring role, and reduces the installation difficulty and improves the installation efficiency. The platform secondary beam 1-2 is the secondary load-bearing component of the load-bearing platform 1, which is installed above the platform main beam 1-1. The role of the platform secondary beam 1-2 is to distribute the load on the platform to the platform main beam 1-1, thereby realizing effective load transfer. A plurality of platform secondary beams 1-2 are arranged at intervals along the length direction of the platform main beam 1-1, which can ensure uniform load distribution and improve the overall stability of the platform. The platform main beam 1-1 and the platform secondary beam 1-2 can be connected by detachable connection bolts, so that they can be disassembled for subsequent reuse.

[0026] In order to further ensure the stability of the load-bearing platform 1, in the embodiment, an anti-sliding shaft seat 8 is installed above the platform girder 1-1, the tension support 4 includes a tension embedded part 4-1 and a tension connecting seat 4-2, the tension embedded part 4-1 is used for pre-embedding in the main structure 7, the tension connecting seat 4-2 is an integral structure with the tension embedded part 4-1 and is exposed outside the main structure 7, the inclined pull rod 2 is connected between the anti-sliding shaft seat 8 and the tension connecting seat 4-2, and the load on the load-bearing platform 1 can be dispersed into the main structure 7 through the inclined pull rod 2. The anti-sliding shaft seat 8 and the tension connecting seat 4-2 provide a connection point for the inclined pull rod 2. The anti-sliding shaft seat 8 is installed above the platform girder 1-1, which can also prevent the platform girder 1-1 from sliding under the action of load. The inclined pull rod 2 provides additional tension by connecting the anti-sliding shaft seat 8 and the tension connecting seat 4-2, further enhancing the stability of the platform girder 1-1. The tension support 4 transmits the tension of the inclined pull rod 2 to the main structure 7 through the tension embedded part 4-1, ensuring that the load can be effectively transmitted to the main structure and avoiding local overload. The platform girder 1-1 transmits the load on the platform to the main structure 7, ensuring the overall stability of the structure. The tension connecting seat 4-2 and the tension embedded part 4-1 are an integral structure, which can improve the integrity and reliability of the structure and reduce the probability of separation at the connection between the two. The structure can effectively prevent the platform girder 1-1 from sliding or deforming under the action of load through the combined action of the anti-sliding shaft seat 8 and the inclined pull rod 2, and the tension of the inclined pull rod 2 is transmitted to the main structure 7 through the tension connecting seat 4-2, ensuring that the load can be effectively transmitted and avoiding local overload; through the integrated design and the use of embedded parts, the overall integrity and construction efficiency of the structure are effectively improved.

[0027] Since the installation height of the load-bearing platform 1 may need to be adjusted according to the site, in order to be able to install the load-bearing platform 1 at different heights to meet the needs of different atrium structures, the inclined pull rod 2 in the embodiment is designed as a length-adjustable structure. Specifically, the inclined pull rod 2 can be composed of an adjusting rod one 2-1 and an adjusting rod two 2-2. The adjusting rod one 2-1 is a full-thread rod or has a threaded segment 2-1-1. The adjusting rod two 2-2 has a threaded hole matched with the threaded segment 2-1-1. The length of the adjusting rod one 2-1 located in the adjusting rod two 2-2 can be adjusted by screwing, that is, the length of the whole inclined pull rod 2 is adjusted by rotating the adjusting rod one 2-1 and the adjusting rod two 2-2 to connect with the anti-slip shaft seat 8 on the load-bearing platform 1. The adjusting rod one 2-1 is pivoted with the anti-slip shaft seat 8, and the adjusting rod two 2-2 is pivoted with the tension connection seat 4-2. The pivoting is achieved by a rotating shaft, so that the adjusting rod can rotate within a certain range to adjust the angle, so that the structure can better adapt to different geometric conditions and stress states during installation and use. The pivoting mode provides higher flexibility, so that the adjusting rod can be adjusted in angle according to actual needs, so as to better adapt to complex engineering environment and meet the construction needs of the atrium. The pivoting design also makes the connection between the adjusting rod and the anti-slip shaft seat 8 or the tension connection seat 4-2 more convenient, without the need for complex fixing devices to achieve quick installation, and can effectively transfer the load to the main structure 7 while dispersing the load to avoid local overload. This connection mode can optimize the stress path of the structure, improve the overall stability and reliability of the structure.

[0028] The platform main beam 1-1 in the embodiment is installed below a support seat 9. The upper end of the inclined strut beam 3 is connected with the support seat 9, and the lower end of the inclined strut beam 3 is connected with the inclined strut support 5, so as to ensure the stability of the bottom of the platform main beam 1-1 and avoid the phenomenon of downward movement of the platform main beam 1-1 under heavy load. The inclined strut beam 3 can also be designed as a length-adjustable type, which is similar to the structure of the inclined pull rod 2. Specifically, in order to improve the construction efficiency, the inclined strut support 5 includes a supporting beam 5-1 and a fixed support 5-2. The fixed support 5-2 is used to be fixed in the main structure 7. The supporting beam 5-1 is connected between two fixed supports 5-2 and is arranged towards the inclined strut beam 3 to support the inclined strut beam 3. The contact part between the inclined strut beam 3 and the supporting beam 5-1 is provided with an anti-slip protection piece 10, which is a semi-enclosed structure and is sleeved on one end of the inclined strut beam 3.

[0029] An operation and protection platform 6 is erected below the load-bearing platform 1. The operation and protection platform 6 is composed of steel pipe scaffolding, step board and safety net. The operation and protection platform 6 is a two-layer structure and is erected on the inside frame of the atrium below the load-bearing frame to ensure construction safety.

[0030] The high-altitude large-span atrium structure load-bearing frame structure of the embodiment is simple and ingenious, compared with a traditional floor-type scaffold (the floor-type scaffold is high in height and high in requirement for bearing capacity of a frame body foundation structure), the load-bearing platform 1, the inclined pull rod 2, the inclined support beam 3, the tension support 4 and the inclined support support 5 are arranged, the operation platform frame body is arranged on the load-bearing platform 1 to construct the atrium structure, that is, a non-floor-type scaffold structure is adopted, the erection time and erection materials of the scaffold are greatly reduced, the construction efficiency of the atrium structure is improved, the construction period of the main structure is shortened, the construction safety hazard is reduced, the construction cost investment is reduced, the construction method of assembly makes the components reusable, the material loss is reduced, the green construction development concept is met, and the high-altitude large-span atrium structure is conducive to popularization and application in the field of building construction technology.

[0031] A construction method of a high-altitude large-span atrium structure load-bearing frame structure mainly includes the following steps. S1, both ends of the platform main beam 1-1 are lapped on the main structure 7 at the atrium position, and the platform secondary beam 1-2 is subsequently installed above the platform main beam 1-1 to assemble the load-bearing platform 1; S2, the inclined pull rod 2 is connected with the tension support 4 and the load-bearing platform 1 pre-buried in the second layer below the atrium structure in sequence, wherein the second layer below refers to a position of the second layer from the top layer of the building downwards; S3, the inclined support beam 3 is connected with the load-bearing platform 1 and the bearing beam 5-1 in the inclined support support 5 in sequence, and the inclined support beam 3 is connected at 1 / 4 of the platform main beam 1-1; S4, the bearing beam 5-1 in the inclined support support 5 is connected with the fixed support 5-2 in the frame column of the main structure 7 pre-buried in the fourth layer below the atrium structure; S5, the steel pipe scaffold, the step plate and the safety net are used to erect the operation and protection platform 6 at the first and second layers below the load-bearing platform 1, and the operation and protection platform 6 is divided into upper and lower layers; S6, the operation platform frame body 11 is erected on the load-bearing platform 1 to construct the atrium structure; S7, after the atrium structure construction is completed and the concrete strength of the atrium structure reaches the design requirement, the operation platform frame body 11, the inclined support beam 3, the inclined support support 5, the inclined pull rod 2, the tension support 4, the load-bearing platform 1 and the operation and protection platform 6 are sequentially removed.

[0032] The construction method of the load-bearing frame structure of the high-altitude large-span atrium structure in the embodiment greatly reduces the erection height of the load-bearing scaffold, reduces the material consumption of the scaffold, effectively shortens the scaffold erection period, and improves the construction efficiency of the high-altitude large-span atrium structure.
