[0002] Roof tube trusses are generally made of steel materials and are one of the main types of building structures. The tube truss structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates, and uses silanization, pure manganese phosphating, water washing and drying, galvanizing and other rust removal and rust prevention processes. Welds, bolts or rivets are usually used to connect the components or parts. Because the tube truss structure is light in weight and simple to construct, it is widely used in large factories, venues, super high-rise buildings and other fields.

[0003] At present, the traditional construction method of roof tube trusses usually uses hoisting equipment to hoist the tube trusses. However, the traditional construction method often cannot effectively reduce the vibration of the tube truss structure during the hoisting process, which not only affects the construction quality, but also may cause potential damage to the structure, thereby affecting the stability of the overall structure of the tube truss. Therefore, how to effectively reduce the vibration during the hoisting process and improve the construction quality and structural stability has become a problem that needs to be solved urgently.

[0022] The present application embodiment discloses a large-scale multi-layer roof tube truss construction method. Figure 1 , including the following steps: Step 1: According to the actual situation of the construction site, the construction area is reasonably divided into multiple construction units to facilitate construction in different areas and stages; Step 2: Install a special construction frame 1 at each construction unit location. The construction frame 1 is provided with a liftable installation platform 3. The design of the construction frame 1 needs to take into account stability and load-bearing capacity to ensure safety during the construction process; Step 3: First, complete the installation of the bottom roof pipe truss at the divided construction unit. When installing the pipe truss, first complete the assembly of the overall structure of the pipe truss at the construction site, then hoist the assembled pipe truss to the installation position and fix it to the main structure of the building; after completing the installation of the bottom roof pipe truss, adjust the position of the construction frame 1, and firmly fix the installed bottom roof pipe truss on the construction frame 1 to prevent damage to the connection nodes of the pipe truss due to construction vibration during the subsequent construction process; Step 4: After the pipe trusses of the upper roof are assembled at the construction site, they are hoisted onto the installation platform 3. By driving the installation platform 3 up and down, the pipe trusses of the upper roof are accurately moved to the predetermined installation position, and the installation and fixing work is completed; When the corresponding roof tube truss structure layer is completed, the installation platform 3 is first separated from the tube truss structure layer, and the quality of each connection node of the tube truss is inspected. If there are deviations or unqualified parts, they are adjusted and repaired in time to ensure construction quality and safety.

[0023] Step 5: After installing the upper layer of roof tube trusses, first cancel the support and fixation of the construction frame 1 on the lower layer of roof tube trusses, and readjust the position of the construction frame 1. Then, fix the installed uppermost layer of roof tube trusses to the construction frame 1. Then, assemble the upper layer of roof tube trusses and hoist them onto the installation platform 3 to install the upper layer of roof tube trusses.

[0024] Step 6: Repeat the above step 5 until the construction and installation of the roof pipe trusses of each layer are completed; during the construction process, the position and stability of the construction frame 1 need to be continuously checked and adjusted to ensure the construction quality and safety.

[0025] The special construction frame 1 and the lifting installation platform 3 are used to support and fix the lower layer of pipe trusses. When the pipe trusses are hoisted, the pipe trusses are hoisted on the installation platform 3. The construction frame 1 bears the impact force of the pipe trusses during hoisting, thereby reducing the vibration impact on the installed pipe trusses at the lower layer, ensuring the construction quality and structural stability. And by reasonably dividing the construction area and constructing in stages, the construction process is made more orderly and efficient, realizing the efficient and stable construction of large multi-story roof pipe trusses.

[0030] By slidingly setting a plurality of support rods 2 on the construction frame 1, and driving each support rod 2 to slide, the support block 23 on each support rod 2 is pressed against the bottom wall of the installed pipe truss, so that the pipe truss can be supported and fixed; and by slidingly setting a support sleeve 21 on the support rod 2, adjusting the position of the support sleeve 21 on the support rod 2 by rotating the limit screw 24, and rotatably setting the support block 23 on the support sleeve 21, the position of the support block 23 on the support rod 2 can be flexibly adjusted within a certain range, so that the support block 23 can be accurately moved to the bottom of the pipe truss to be supported and support it, thereby improving the convenience of use.

When the pipe truss is hoisted onto the mounting platform 3, the shock absorbing springs 32 can absorb and buffer the vibration energy, thereby protecting the pipe truss structure from damage.

[0033] Reference Figure 5 The mounting platform 3 is provided with a top support mechanism for preventing the shock-absorbing platform 31 from sliding. The top support mechanism includes a top support frame 33 slidably arranged on the mounting platform 3 in a vertical direction, and a driving component for driving the top support frame 33 to slide.
