Description

Technical Field

[0001] The invention relates to an assembled frame system for installing floors. Background Art

[0002] In the prior art, outdoor scenic spots, leisure places, amusement parks and other places often use floor systems supported by keel structures, because the ground installed outdoors is often not flat. Unlike the ground leveling in indoor buildings, the ground conditions outdoors are basically impossible to be flat, and the outdoor floor system is mainly to provide pedestrians with a leisure and sightseeing route. Therefore, the installation of the floor must not damage the original ground environment. At present, the installation of outdoor floor systems adopts a method of using preset piles, installing keels on the top of multiple piles, and then laying the floor. However, the keel is currently installed on the pile by welding, and the metal pipes that make up the keel are welded to each other. However, this welding structure is difficult to ensure the flatness of the keel system. Since the volume of the pile cannot be too large to affect the appearance, and the number cannot be installed too much, for the horizontal plane formed by the keel system, each pile is equivalent to a fulcrum, and the entire keel system must be supported on multiple fulcrums. It is very difficult to perform welding operations and finally find comprehensive flatness. This is why the current outdoor floors have the problem of local undulations and are not smooth enough. Moreover, because the entire floor system is exposed to wind, rain and pedestrian trampling outdoors all year round, the bottom supporting structure is only a pile body, and the supporting stability is far less than that of the floor in indoor buildings. Therefore, after long-term use, the welding points of the keel system are prone to breakage, which requires maintenance. Such problems are likely to cause deformation of the skeleton structure. The re-welding method has the following defects: first, the operation is cumbersome and the maintenance cost is high. Second, after welding, the maintenance position and the flatness of the entire skeleton system will be broken again, causing the flatness of the entire floor system to be reduced again, affecting subsequent use. In short, the current keel structure installation, the connection between the floor and the keel structure, and the connection between the keel structure and the pile body all have many defects, and the installation and maintenance manpower and material costs are high, affecting the effect expression of the entire floor system. Summary of the invention

[0003] The present invention provides an assembled skeleton system for installing floors, which has a reasonable structural design. The skeleton structure is composed of improved pipe fittings. Adjacent pipe fittings are quickly assembled and connected by special connectors without welding. Bolts are directly used to position and connect the connectors to two adjacent pipe fittings respectively, thereby forming the entire skeleton structure. Moreover, through the assembly between the pipe fittings and the connectors, the flatness of the skeleton structure can be achieved, so that a plurality of pipe fittings can be on the same horizontal plane. In addition, special pile body connectors and floor connectors are designed and manufactured, so that the skeleton structure and the pile body can be quickly assembled, and the skeleton structure and the floor can be quickly assembled, thereby forming the entire skeleton system. The assembly and connection process does not require any welding, so that the assembled structure of the entire system is achieved, labor costs are saved, installation efficiency is improved, and subsequent maintenance is convenient. When problems occur, the structural parts and connectors can be replaced at will, and they can be replaced and supplemented, and the flatness and integrity of the original system will not be damaged. The entire skeleton system can significantly improve the flatness of the floor after installation, providing a more popular and feasible solution for the installation of outdoor floors, and solving the problems existing in the prior art.
