- 1 A PREFABRICATED PANEL AND ITS FIXED INSTALLATION STRUCTURE TECHNICAL FIELD [0001] This invention relates to a building material, specifically relates to a building prefabricated panel and its fixed installation structure. BACKGROUND ARTS [0002] The so-called structure refers to a plane or space system that is able to withstand the impact (load) connected by several members (the units composed of the structure, such as the beam, slab and pillar etc). Due to different building materials, the building structure can be divided into concrete structure, masonry structure, steel structure, light steel structure, timber structure and composite structure. However, depending only on the structure can not meet the basic requirements of the building such as wind and rain prevention, additional enclosing measures (such as wall and roof) are also needed on the basis of the structure. [0003] Steel structure building refers to the residential building that uses steel as load bearing beam and pillar, which owns below advantages: 1. Light weight and strong strength. 2. Safe and reliable with good seismic and wind resistant performance. 3. The steel structure members are manufactured in the factory, which means to reduce the on-site workload and shorten the construction period for meeting the requirements of industrialization. 4. The steel structure members are manufactured in the factory, which owns the advantages of reliable quality, accurate dimension, easy installation and easy matching up with relevant components. 5. Steel can be recycled, which means less environmental pollution for structure construction or dismantlement. [0004] Among the above advantages, "The steel structure members are manufactured in the factory, which means to reduce the on-site workload and shorten the construction period -2 for meeting the requirements of industrialization" is the current most advanced concept globally, which is the building product's industrialized production pursued globally. [0005] In order to respond positively to the requirement of building industrialization, the enclosure part, as an important part of steel structural house, is required to be compatible with the development of steel structural members, which can be manufactured in the factory and assembled on site with the ready-constructed steel structural members. SUMMARY OF INVENTION [0006] One purpose of this invention is to provide a prefabricated panel conveniently and rapidly applied to the wall, roof as well as floor for responding positively to the requirement of building industrialization and specifically aiming at the structural characteristics of steel structural members. This prefabricated panel is manufactured in the factory, it is only needed to assemble with the ready-constructed structural members (such as steel structure) to form an enclosing part on site. [0007] The technical solution for this invention employs is: a prefabricated panel comprises the light steel frame as well as front and rear plates, the recited light steel frame includes the left and right side frames as well as upper and lower side frames, which enclose to form a square frame. The U-shaped notches of the left and right side frames are set towards left and right respectively, which enables the prefabricated panel to insert with structural members that used to fix the prefabricated panel via the left and right U-shaped notches. The recited front and rear connecting arms of the left and right side frames are provided with mounting holes for screw penetration to fix the prefabricated panel onto the structural members. The recited front and rear plates are laid on the light steel frame as the front and rear panels of the light steel frame respectively, the top and bottom surfaces of the recited upper and lower side frames are exposed.

The left prefabricated panel located on the left of the square tube, matches up with the corresponding threaded holes on the square tube successively through the front panel on the left prefabricated panel as well as the mounting hole of the front connecting arm on the right side frame of the left prefabricated panel via the screw. The right prefabricated panel located on the right of the square tube, matches up with the corresponding threaded holes on the square tube successively through the front panel on the right prefabricated panel as well as the mounting hole of the front connecting arm on the left side frame of the right prefabricated panel via the screw. [0019] Outer side of the rear panel on the left and right prefabricated panels is provided with fireproof decorative panel. The fixed installation structure of the fireproof decorative panel on the square tube is as below: the fireproof decorative panel matches up with the corresponding threaded holes on the square tube successively through the decorative panel itself and the rear panel of left prefabricated plate as well as the mounting hole of the rear connecting arm on the right side frame of the left prefabricated panel via the screw, and fixed to the square tube with the left prefabricated plate together. The fireproof decorative panel matches up with the corresponding threaded holes on the square tube successively through the decorative panel itself and the rear panel of the right prefabricated plate as well as the mounting hole of the rear connecting arm on the left side frame of the right prefabricated panel via the screw, and fixed to the square tube with the right prefabricated plate together. [0020] The fixed installation structure of the fireproof decorative panel on other positions is as follows: the fireproof decorative panel is fixed to the rear plate of the left and right prefabricated panels by the effect between the screw and the rear plate of the left and right prefabricated plates.

-6 [0021] The beneficial effects of this invention is: In order to keep in line with the materials of the steel structure, the in-built light steel frame in the prefabricated panel of this invention, which takes advantage of the "skin effect" technical principles to lay the light panels (such as magnesium board, fiber cement board, OSB board etc) in outer side, has played a stronger performance than a single material and got the achievement of "1 plus 1 is more than 2". The light steel frame set in the prefabricated panel are exposed around the prefabricated panel, therefore, the prefabricated panel of the invention takes advantage of the current steel structure connecting technology (such as bolt connection, welding and anchorage etc) for effective and easy connection with the steel structure. Meanwhile, due to the use of light steel frame, the prefabricated panel of this invention is easy and rapid to connect with the steel structure, the plate bears the load with the structure by its own mechanical property, which can effectively replace the auxiliary members (such as diagonal bracing and tie rod etc) in the steel structure by reasonable setting. The prefabricated panel of this invention can be insulated from heat and sound by filling with insulation materials. [0022] In addition, the modular dimension of this prefabricated panel can be based on the usual width of ordinary panel in the market, which can reduce the cutting and waste of the panel. Production line can be achieved for the panel manufacturing and robotic welding can be used for the welding of light steel frame, which enables the product to reach good quality and have clear load bearing. All the fixing of lightweight panels is by screws and it facilitates the factory production. [0023] If the plate itself of the prefabricated panel which laid outside is water resistant and also includes the structural measures such as waterproof membrane, then the waterproof and moisture-proof performances can be achieved. Therefore, front and rear plates as well as fireproof decorative panel lay in the surface of the prefabricated panel enclose the light steel panel to reach the airtight performance such as fire and water resistance.
