DETAILED DESCRIPTION

[0018] The following embodiments are only descriptive, not limiting, and cannot limit the protection scope of the utility model.

[0019] The suspended platform system includes a pile foundation 9, a main beam 6, a secondary beam 5, timber 4, wooden planks 3, and bamboo plywood 2. Its key feature is the inclusion of a suspension bolt 1, made of large-diameter round steel, which is mounted on the top of the pile foundation. The suspension bolt includes a horizontal section, an inclined section, and a vertical section. The horizontal section has inclined sections that bend outwards at both ends. These inclined sections serve two purposes: firstly, to avoid obstructing the outer edge of the pile foundation, and secondly, to provide space for the installation of the main beam. Vertical sections are formed by bending downwards at the base of the two inclined sections. External threads are provided on the two vertical sections, and the main beam is fitted onto the two vertical sections. The lower end of the main beam is limited by washers 7 and nuts 8 installed on the vertical sections. Secondary beams are laid on the upper end of each main beam, perpendicular to the direction of the main beam. Wooden planks are laid on the upper end of the secondary beams via timber, and bamboo plywood is laid on top of the wooden planks. The timber slabs, measuring 100mm x 150mm, are tied to the secondary beams. The wooden planks, made of 30mm thick wood, are nailed to the timber slabs. The bamboo plywood, made of 10mm thick bamboo plywood, is laid on top of the wooden planks.

[0020] Since many upward-extending steel bars will be exposed at the top of the pile foundation, in order to facilitate the installation of the capping bolt on the pile foundation, this utility model designs the capping bolt into three parts. The first part consists of a first horizontal part 10, an inclined part 13, and a vertical part 14 formed by bending and forming one piece. The second part is a welded connection part 11. The third part consists of a second horizontal part 12, an inclined part, and a vertical part formed by bending and forming one piece. During construction, the first part and the third part are inserted from both sides of the pile foundation, and then the first part and the third part are welded together by welding using the welded connection part.

[0021] The main beam includes channel steel and connecting bolts. The slots of the two channel steels are arranged in opposite directions. The vertical part is clamped between the two channel steels. The two channel steels are connected by the cooperation of the spaced connecting bolts and nuts.

[0022] To further enhance the stability of the bolts installed on the pile foundation, this utility model also designs a reinforcing rib plate 15, which is sandwiched between the vertical part of the secondary beam and the pile foundation.

[0023] In use, first, according to the actual situation, the diameter of the sling bolt and the type of the main beam and the secondary beam are determined by calculation to ensure that the planned pouring of concrete weight and the self-weight of the bottom lifting platform system and other loads can be safely and stably borne. In operation, the sling bolt is directly hung on the pile top of the pile foundation, the two vertical parts of the sling bolt are vertically hung on both sides of the pile foundation, the distance between the first part and the third part of the sling bolt is adjusted, one end of the main beam is threaded on the vertical part, then the fixing of the welding connection part is carried out, the main beam is lifted by using the gasket and the nut to tighten the vertical part, the other end of the main beam is hung on the adjacent pile foundation in the same way, the height and flatness of the main beam are adjusted by loosening the nut below, a 10mm thick steel plate is welded between the vertical part of the sling bolt and the pile foundation as a reinforcing rib plate to prevent the deformation of the sling bolt.

[0024] After the suspension of the main beam is completed, the secondary beam is laid above the main beam in the direction perpendicular to the main beam (the general interval is 300-500mm), in order to ensure the stability of the secondary beam, the secondary beam and the main beam can be spot welded. The 100mm*150mm wooden square is bound on the secondary beam in the direction thereof by using the iron wire, and then the 30mm thick wooden plate is nailed on the wooden square by using the nails, and the wooden plate needs to be fully laid to prevent concrete leakage during pouring. Finally, in order to ensure the smoothness of the bottom of the cast-in-place concrete member, a layer of 10mm thick bamboo plywood is laid on the wooden square.

[0025] When the bottom is removed, the main beam can be lifted by using the hand-operated hoist, and after the nut is loosened, it is gradually lowered, and after the sling bolt is cut off, the bamboo plywood, the wooden plate, the wooden square, the secondary beam and the main beam are removed layer by layer.

[0026] Although the embodiments and drawings of the utility model are disclosed for the purpose of illustration, those skilled in the art can understand that various substitutions, changes and modifications are possible without departing from the spirit and scope of the utility model and the appended claims, therefore, the scope of the utility model is not limited to the disclosed contents of the embodiments and drawings.
