Description

Technical Field

[0001] This invention belongs to the field of reticulated roof construction, and specifically relates to a concealed drainage construction method for steel-aluminum composite roofs. Background Technology

[0002] Cantilevered roofs are a common structural design in steel structure buildings. The structure consists of a flat grid roof at the top and tree-shaped supports at the bottom of the grid. The perimeter of the grid roof extends beyond the tree-shaped supports to form a cantilevered shape.

[0003] As architectural aesthetics become increasingly demanding, roofs often feature undulating shapes, such as ribbons. While these structures are aesthetically pleasing, they are prone to drainage problems and can easily accumulate large amounts of water, leading to safety hazards in the roof structure.

[0004] To this end, CN110029783B discloses a siphon drainage installation process that sets the drainage inside a tree-shaped steel column to achieve concealed drainage.

[0005] The existing technology can be referred to in Figure 8 of the aforementioned patent. Currently, the drainage pipe and the tree-shaped steel column are separate structures. Therefore, when connecting them, the tree-shaped steel column is first suspended and placed on the drainage pipe. After welding the drainage pipe together, the tree-shaped steel column is then connected. The drainage pipe and the tree-shaped steel column need to be lifted separately, which is a complicated process. Furthermore, with a large number of lifting devices, interference and conflict between the devices can easily affect the construction. Therefore, the overall construction efficiency is slow, the cycle is long, and the cost is high. Summary of the Invention

[0006] This invention provides a prefabricated pipe section assembly device to solve the technical problem of completing the splicing, alignment and tensioning of prefabricated pipe sections in one step.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a concealed drainage construction method for a steel-aluminum composite roof, wherein the roof comprises a roof surface and tree-shaped steel columns, and includes a roof water collection structure and an indoor drainage structure. The roof water collection structure is located on the roof surface, and the indoor drainage structure is located on the supporting columns. The roof water collection structure is connected to the indoor drainage structure, and the indoor drainage structure is connected to an underground sump. The roof water collection structure is installed at intervals on the roof and includes rainwater gutters, downpipes and horizontal water collection pipes. The rainwater gutters are located inside the roof structure, and the downpipes extend from the bottom of the rainwater gutters and then converge on the horizontal water collection pipes. The tree-shaped steel column includes a bottom main support, a bifurcated adapter joint, and a top branch support; The indoor drainage structure includes a lower rainwater pipe, a bend joint, and an upper rainwater pipe. The lower rainwater pipe is fixed inside the bottom main support rod, the bend joint is fixed inside the bifurcated adapter joint, and the upper rainwater pipe is fixed inside the top branch rod. The bend joint includes a middle bend main pipe and telescopic support rods at both ends. The telescopic support rods are telescopically mounted on the bend main pipe. The lower rainwater pipe is connected to the underground sump, and the upper rainwater pipe is connected to the horizontal sump pipe. The construction steps include, S1. Component prefabrication: Before construction, the components of the roof water collection structure and indoor rainwater drainage structure are prefabricated and transported to the construction site. S2. Pre-installation of roof drainage structure: Install the roof drainage structure on the roof and hoist it together with the roof. S3. Provide temporary support for the roof; S4. Weld the downpipe, elbow joint, and uppipe to the bottom main support, the forked transition joint, and the top branch support respectively using steel bars. S5. Install the bottom main support rod, the forked adapter and the top branch rod in sequence. When connecting, pull the telescopic support rod out to a suitable distance and then connect it to the lower rainwater pipe and the upper rainwater pipe respectively by thread. Finally, connect the upper rainwater pipe and the horizontal water collection pipe through a three-way valve.

[0008] Preferably, the top end of the lower rainwater pipe and the bottom end of the upper rainwater pipe are provided with internal threads, and the telescopic support rod is provided with external threads.

[0013] Preferably, the bottom of the roof is provided with a hanger corresponding to the horizontal water collection pipe.

[0014] Preferably, a filter screen is provided at the bottom of the rainwater trough.

[0015] The beneficial effects of this invention are as follows: 1. A roof water collection structure is set up at the location on the roof where water is prone to accumulate to collect rainwater in a unified manner, and then the rainwater is discharged through an indoor rainwater discharge structure hidden on the support column, so as to drain the water on the roof in time, ensure the safety of the building structure, and avoid damage to the aesthetics of the building. 2.

The lower rainwater pipe 41 is connected to the underground sump, and the upper rainwater pipe 43 is connected to the horizontal sump 33. The construction steps include, S1. Component prefabrication: Before construction, the components of the roof water collection structure 3 and the indoor rainwater structure 4 are prefabricated and transported to the construction site. S2. The roof water collection structure 3 is pre-installed, and the roof water collection structure 3 is installed on the roof 1 and hoisted together with the roof 1. S3. Provide temporary support for roof 1; S4. The lower rainwater pipe 41, the elbow joint 42, and the upper rainwater pipe 43 are respectively welded to the bottom main support 21, the forked adapter joint 22, and the top branch rod 23 by steel bars. The elbow main pipe 421 of the elbow joint 42 is welded and fixed to the forked adapter joint 22. Both ends of the elbow joint 42 extend out of the forked adapter joint 22. There is a gap between the top of the lower rainwater pipe 41 and the top surface of the bottom main support 21, and there is a gap between the bottom of the upper rainwater pipe 43 and the ground of the top branch rod 23. This makes it convenient to connect the elbow joint 42 to the forked adapter joint 22 and to connect the elbow joint 42 to the lower rainwater pipe 41 and the upper rainwater pipe 43 respectively. S5. Install the bottom main support rod 21, the forked adapter 22 and the top branch rod 23 in sequence. When connecting, pull the telescopic support rod 422 out to a suitable distance and then thread it to the lower rainwater pipe 41 and the upper rainwater pipe 43 respectively. Finally, connect the upper rainwater pipe 43 and the horizontal water collection pipe 33 through a three-way valve.

[0021] Furthermore, the top end of the lower rainwater pipe 41 and the bottom end of the upper rainwater pipe 43 are provided with internal threads, and the telescopic support rod 422 is provided with external threads.

[0022] Furthermore, the main pipe 421 is curved in the middle and straight at both ends. The inner sides of both ends of the main pipe 421 have limiting rings 423.

[0026] Furthermore, the bottom of the roof 1 is provided with a hanger corresponding to the horizontal water collection pipe 33, which can ensure the structural stability of the roof water collection structure 3.

[0027] Furthermore, the rainwater trough 31 includes a permeable cover and a water collection trough, which is a sunken structure. It is installed in the roof structure 1 to collect rainwater from the roof 1 and discharge it through the downpipe 32. The permeable cover is located at the top of the water collection trough and is flush with the roof 1. The bottom of the water collection trough is preferably equipped with a filter screen to avoid clogging.

[0028] The present invention sets up a roof water collection structure 3 at the location on the roof 1 where water is prone to accumulate to collect rainwater in a unified manner, and then drains the rainwater through an indoor rainwater discharge structure 4 hidden on the support column. This timely drainage of water accumulated on the roof 1 ensures the safety of the building structure and avoids damage to the building's aesthetics. Furthermore, the ingenious design of the indoor drainage structure 4 and its combination with the tree-shaped steel column 2 allows the segmented indoor drainage structure 4 to be pre-fixed to the segmented tree-shaped steel column 2, eliminating the need for separate lifting. This reduces the construction of equipment and the potential hazards caused by cross-operations, saves construction steps, simplifies the construction process, improves construction efficiency, saves labor, increases the safety factor, reduces the construction cycle, and saves costs.
