Embodiment Construction
[0018] According to Figure 1 and Figure 2, wire ropes are inserted into the inner holes of the pipe fittings, the pipe fittings are connected with steel plates, and a guide piece is installed at one end of the pipe fittings. The steel wire ropes in the pipe fittings are pre-tensioned and pre-tensioned to the pre-designed tensile force. So far, after pre-tensioning to the required tension, the two ends of the rope are sealed with plugging heads, and the ultra-light structural unit is made. The ultra-light structural unit is connected with steel plates to make various beam module frames. The space of the frame is filled with structural blocks composed of lightweight fillers or pressurized plastic bottles, polyurethane and heat shrinkable film, and decorative surfaces are installed on the surface of the various beam module frames filled with fillers.

A manufacturing method and its components for inner-tension pre-stress extra-light structure wall surface comprises the following steps: a steel wire rope is threaded in inner holes of pipe fittings, a steel plate is used to connect pipe fittings, guidance pieces are arranged at one ends of pipe fittings, and the steel wire rope in pipe fittings is pre-tensioned to required design tension. After required tension is pre-tensioned, both ends of the rope are sealed with plugs and the extra-light structure is formed. A beam frame is arranged between the extra-light structure unit with connection of steel plate, light fillings or structural blocks made of inflated plastic bottle, polyurethane and thermal shrinkage film are filled in the frame space. A steel plate punched joggle piece is arranged at the surrounding of the frame. A plastic intrusion plate with thermal and sound insulation performance is arranged on the external surface of the frame which is filled with the fillings or the structural blocks, and an external decoration layer is used on both sides of the frame. The present invention has the advantages that varieties of beam and bridge, suspended bridge and floating bridge are manufactured with less materials, low prices, and high rigidity and strength, and are applicable for mass production and module construction. The applications range from single room on single floor, a plurality of rooms on single floor, two floors, three floors and high building, large building, to bridge or waterborne building. On saving energy and reducing cost, the utilization of the waste shows excellent performance.
Description
Technical field [0001] The invention relates to the technical field of new materials, in particular to a manufacturing method and components of various beam modules with an internally tensioned prestressed ultra-light structure. Background technique [0002] Nowadays girders, bridges, and pontoon suspension bridges are generally made of reinforced concrete or welded with steel structure. This requires a lot of cement and steel. The beams made are very heavy, and the weight of the building can only be increased. On-site construction, increasing the transportation volume and the place for stacking materials, brings great inconvenience to the construction. Summary of the invention [0003] The purpose of the present invention is to develop a manufacturing method and components for various girder modules with internally tensioned prestressed ultra-light structures that are convenient for construction, do not require a large construction site, and can be industrially produced. [000...
