Description

Fixing structure of gypsum keel Technical Field The utility model relates to the field of keels for buildings, in particular to a fixing structure of a gypsum keel. Background The light steel joist and the wooden joist are indispensable materials in the fitment, and the specification model of light steel joist is numerous, roughly falls into furred ceiling fossil fragments and for the partition wall two kinds, and the furred ceiling fossil fragments include main joist, auxiliary joist, limit fossil fragments, and the main joist is fixed with top stress surface earlier when furred ceiling, then fixes auxiliary joist and main joist, and the edge uses limit fossil fragments to be fixed with the wall, and limit fossil fragments are fixed with auxiliary joist, and the last screw is fixed with gypsum board and auxiliary joist completion furred ceiling. The partition wall fossil fragments include world fossil fragments, vertical fossil fragments, the heart fossil fragments, during the partition wall, fix U type world earthworm bone respectively upper and lower stress surface earlier, then place the vertical fossil fragments along upper and lower direction between the world earthworm bone, pass the heart fossil fragments again and play the reinforcement effect, it is fixed to use the screw to fix gypsum board and vertical fossil fragments at last, accomplish the furred ceiling, the timber fossil fragments can understand the square of rectangle, it is simpler to compare light steel joist construction, fix timber fossil fragments and stress surface earlier with the nail, then according to required molding construction, use the screw to fix gypsum board and timber fossil fragments at last, accomplish the construction. Meanwhile, in construction, the gypsum board is required to be fixed on the light steel joist by using screws, after the screws penetrate through the light steel joist, a galvanized layer on the surface of the light steel joist is damaged, so that the galvanized layer is gradually oxidized in the air, finally the light steel joist is rusted, the self strength is reduced, the risk of gypsum board falling is caused, meanwhile, the light steel joist is more in variety, multiple specifications are required to be combined for use, the structure is complex, the construction difficulty is increased, the light steel joist is formed by bending strip steel, the volume is greatly increased after a cavity is formed in the middle, the whole is heavier due to the fact that the volume is increased, the transportation cost is higher due to the fact that the self weight is higher, the edge is sharp after cutting in construction, constructors are scratched easily, the light steel joist is produced after rusting in order to prevent the light steel joist from being fixed in the air, the adhesive layer is required to be used in the construction, the adhesive layer is influenced, the adhesive layer is more, the joint of the adhesive layer is required to be used in the construction, the joint is poor in the sound insulation performance, and the sound insulation performance is easy to be controlled by the light steel joist. The wooden fossil fragments are wooden material, warp, mould, decay easily after the wet, lead to slightly decline, and long-term exposure is probably breeding the worm ant in humid environment, causes gypsum board fracture easily, and fire behavior is poor, and timber still, and acceleration fire in the conflagration is spread, has the potential safety hazard, and timber consumption is great, probably involves forest resource excessive development, and bearing capacity is limited, and although timber itself bearing capacity is better, but intensity is showing to decline after the wet, and long-term bearing atress can be deformed, need dampproofing, the protection against insects condition of periodic inspection, and the maintenance cost is higher. The production and use costs of the two keels are higher, the performance is unstable, the light steel keels need more complex connecting fittings, and the cooperation is more complex. The wood keels are unstable in connection due to the limited stress area of the connecting fittings and the gypsum keels. Disclosure of utility model The utility model aims to provide a gypsum keel fixing structure, which is characterized in that a cross screw fixing piece, a cross fixing piece, an L-shaped fixing piece, an end fixing piece and a butt joint fixing piece are matched with a gypsum keel structure relative to a traditional connecting piece, so that the integral weight of the gypsum keel is reduced by matching the gypsum keel on the premise of ensuring the installation contact area and the stress area. The utility model is realized by the following technical scheme: The utility model provides a gypsum fossil fragments fixed knot constructs, includes gypsum fossil fragments, alternately screw rod mounting and alternately mounting all include the door type framework, and t
