Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly relates to a pavilion building system with a superimposed layout and double-loop traffic. Background Art

[0002] With the rapid development of China's social economy in the new era, on the basis of the significantly rich material foundation, the people's demand for spirit and culture has become increasingly prominent, which has promoted the birth of a large number of landmark cultural and art centers with complete functions, beautiful shapes, and representing local cultures. Due to the unique functional requirements and symbolic meanings of such cultural and art infrastructure, multiple buildings are generally combined and built to form a special shape. The multiple buildings are interconnected through corridors, passages, etc. to realize the personnel flow between different building structures. Generally, vehicles are parked in the basement. When entering different buildings, the vehicles need to be parked at the corresponding basement elevators and cannot shuttle between several buildings on the ground, which is very inconvenient. The invention patent with the application number 2017100605224 discloses a group high-rise building system, which uses in-area traffic facilities, in-area pipelines, and tray space structures to realize the shuttle of vehicles within the building system and improve traffic efficiency. However, the structure of this system is complex, reducing the use of the building floor area, and the noise and exhaust gas generated by the vehicles pollute each floor. Further, in order to improve the connectivity and artistry between building groups, an opening and closing roof is usually set on the top of the building. However, in the existing opening and closing roof structures, the tracks set are usually exposed on the top of the building. On the one hand, it affects the overall aesthetics, and on the other hand, it is easily corroded by air and rainwater after being exposed for a long time, affecting the opening and closing effect of the roof.

[0007] Preferably, the third spiral ramp truss and the fourth spiral ramp truss have the same structure. The third spiral ramp truss includes a first upper chord member and a plurality of first web members arranged between the first upper chord member and the third spiral ramp truss or the fourth spiral ramp truss.

[0008] Preferably, the corridor includes an inner corridor arranged directly below the corridor and an outer corridor located outside the corridor. The outer corridor is connected to the outer loop road.

[0009] Preferably, an arched corridor opening is arranged at the outer end of the inner corridor.

The layout is simple, connecting the three buildings with each other and between the interior and the exterior, effectively solving the complex traffic problems of multiple buildings.

[0019] The circular atrium structure set increases the aesthetics of the building system, makes full use of the building space, and the first spiral ramp truss and the second spiral ramp truss adopted are symmetrically arranged in a double-spiral circular structure on the six support steel columns, making the overall structure symmetric, the mass of the overall structure is respectively close to the center, improving the overall stability of the structure, and the symmetric arrangement can reduce the construction cumulative error during the installation process of the structure, reducing the construction calibration and composite work during the construction process, and thus reducing the construction cost.

[0020] A fan-shaped roof is set above the circular atrium structure, which can shield the circular atrium structure and enhance the rainproof performance of this part. The fan-shaped roof is connected and installed in a sliding manner, increasing the openness above the circular atrium structure. When the fan-shaped roof is closed, only the fan-shaped roof is exposed. When the fan-shaped roof is opened, the fan-shaped roof and the track are both hidden in the accommodation space, improving the lighting effect, enhancing the overall aesthetics, reducing the phenomenon that the track is easily corroded by air and rain due to long-term exposure, and ensuring the opening and closing effect and service life of the fan-shaped roof.

The first spiral ramp truss 20 includes an inner ramp steel beam, an outer ramp steel beam, and multiple connecting beams fixedly provided between the inner ramp steel beam and the outer ramp steel beam. The connecting beams serve as the support framework for the subsequent walking stairs. The first spiral ramp truss 21 and the second spiral ramp truss 21 serve as the steel framework structure of the walking stairs. The first spiral ramp truss 21 and the second spiral ramp truss 22 have an overlapping part in space. The starting points of the first spiral ramp truss 21 and the second spiral ramp truss 22 are symmetrically arranged on two support steel columns 20 at the diagonal corners of the regular hexagon.

[0036] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , and Figure 6 shown, a construction method of a superposed layout and exhibition hall building system with double-loop traffic, the construction method includes the following steps:

[0037] Step 1, construction of the building main body 1. The three building main bodies 1 are constructed separately and simultaneously according to the drawings. During the construction process, the three building main bodies 1 do not interfere with each other, which can greatly shorten the construction period. During the construction of the first floor, the corridor 5 is constructed and erected, reserving the position of the corridor 5 and installing and erecting the shape of the arched corridor entrance 6. While the building main body 1 is being constructed, the annular atrium structure 2 is constructed. Specifically, first, six support steel columns 20 are constructed. According to the installation drawings, the six support steel columns 20 are respectively vertically arranged at the six vertex positions of a regular hexagon, and then the support frame 26 is fixedly installed at the designated position on the support steel column 20 by welding and the position and angle are corrected; then, the first spiral ramp truss 21 and the second spiral ramp truss 22 are constructed simultaneously. After the construction of the two is completed, then the third spiral ramp truss 23 and the fourth spiral ramp truss 24 are constructed simultaneously. Finally, two arc trusses 25 are installed to complete the construction of the steel structure of the annular atrium structure 2. Finally, concrete is poured and the decorative surface is made.

[0038] Step 2, construction of the connecting corridor 4. After the steel structures of the three building main bodies 1 are erected, the steel structure of the connecting corridor 4 is erected between the top floors (that is, the fifth floor in this embodiment) of two adjacent building main bodies 1. The three connecting corridors 4 can be erected simultaneously, shortening the construction period.

[0039] Step 3: Install the sector roof 8. Install the sector roof 9 at the reserved space at the top of the building main body 1 (i.e., the accommodation space 9 in this embodiment). Specifically, first, install three groups of tracks 10 in the specified directions and fix them in the three accommodation spaces 9 respectively. Then, slide and install the roof truss assembly 11 on the tracks 10. The installation sequence of the roof truss assembly 11 is to first install the driving trolley 111 on the track 10, then fix the main support member 110 on the driving trolley 111, then fix the transverse installation member 112 on the main support member 110, and finally install the sector roof 9 on the roof truss assembly 11 through fasteners and adjust the sector roof 9 to a proper position so that when the three sector roofs 9 are closed, they are closely fitted to each other.

[0040] The above embodiments are only several descriptions of the concept and implementation of the present invention, and do not limit it. Under the concept of the present invention, the technical solutions without substantial transformation are still within the protection scope.
