[0022] Example

[0023] like Figures 1 to 5 As shown, this embodiment provides an assembled overhead chassis, which includes a first chassis unit and a second chassis unit. The two chassis units have the same structure and are connected at the joint by a docking connector to facilitate transportation and on-site assembly.

[0024] This embodiment uses the first chassis unit as a description reference, which includes two first P-type side bones arranged relatively parallel, a second P-type side bone connected to one end of the two first P-type side bones, and a "Z"-shaped main bone whose two ends are respectively connected to the two first P-type side bones and parallel to the second P-type side bones, wherein the cross-sections of the first P-type side bones and the second P-type side bones are the same, and the first P-type side bone is used as a description reference, and the cross-section of the first P-type side bone includes a straight plate portion and a Z-shaped portion vertically connected to the lower portion of the straight plate portion, and when the two are prefabricated and connected in the factory, the P-type side bone is cut 45° at the transition point for welding.

[0025] The other end portions of the two first P-type side frames are provided with mounting holes matching the docking connectors, and the end portions are the docking points. When the first chassis unit and the second chassis unit are connected, the docking points of the first chassis unit and the second chassis unit are butt-jointed and connected through the docking connectors. The cross-section of the docking connectors is in the shape of a "J", and through holes for installation and matching the docking connectors are provided on both sides and the upper end surface.

[0026] In this embodiment, the cross section of the "J"-shaped main bone is in the shape of "J", and a hole is arranged on its upper end surface. When the project is prefabricated and assembled, the two ends of the "J"-shaped main bone are detachably connected to the two first P-shaped side bones through T-shaped connectors, respectively. The T-shaped connector includes a horizontal side portion and a long side portion, and the cross section of the long side portion is in an inverted U shape. A hole with a wire matching the hole is arranged on its upper end surface. The "J"-shaped main bone and the T-shaped connector are aligned with the hole. The "J"-shaped main bone is temporarily connected to the first P-shaped side bones with screws and T-shaped connectors in the factory for easy transportation. When assembled at the construction site, the two ends of the "J"-shaped main bone are fixedly connected to the two first P-shaped side bones through rivets.

[0027] The on-site assembly process of the utility model is as follows:

[0028] ① Carry the two chassis units into the installation space (the unit-type chassis is lightweight and easy to carry);

[0029] ② The two chassis units are connected through the connecting pieces and the side frame feet are installed;

[0030] ③ Chassis positioning (positioned by the position of door openings and window openings) and fixing the footing;

[0031] ④ Remove the temporarily connected "J"-shaped main frame, determine the water and electricity points according to the chassis, and carry out water and electricity transformation;

[0032] ⑤ After the water and electricity are completed, the "J"-shaped main frame is anchored to the first P-shaped side frame with rivets, and the ground support plate is installed to fix the footing under the main frame;

[0033] ⑥ Complete the waterproofing and finishing layer paving of the entire chassis.

[0034] The above is the preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements without departing from the design principle and technical solution of the present invention, and these improvements should also be regarded as the protection scope of the present invention.
