The invention discloses an assembled tile wall surface and a construction method thereof, and relates to the technical field of assembled buildings. The assembled tile wall surface is characterized bycomprising a plurality of keel components fixedly connected to a wall body and assembled base plates fixedly connected to the keel components, wherein the keel components comprise supporting keels and reinforcing keels; the supporting keels are horizontally and fixedly connected to the wall body; the reinforcing keels are horizontally fixed on the wall body and located below the supporting keels;a plurality of supporting hooks with upward openings are evenly distributed on each supporting keel in the horizontal direction; a plurality of reinforcing hooks with downward openings are evenly distributed on each reinforcing keel in the horizontal direction; each assembled base plate comprises a connecting surface facing one side of the wall body and a decorative tile surface away from the side of the wall body; the upper side of the connecting surface is fixedly connected with supporting buckles that are hooked and matched with the supporting hooks; and the lower side of the connecting surface is provided with reinforcing buckles that are sleeved and matched with the reinforcing hooks. The assembled tile wall surface has the advantage of quick construction.

The invention provides a building keel. The building keel comprises an n-shaped galvanized steel sheets, square pillars and bolts, wherein the hollow portions of the n-shaped galvanized steel sheets are filled with the square pillars, and the bolts are used for fixing the n-shaped galvanized steel sheets and the square pillars. Flangings are arranged on the two sides of openings of the n-shaped galvanized steel sheets, bolt holes for mounting of the square pillars are further formed in the two side edges of the n-shaped galvanized steel sheets, and the n-shaped galvanized steel sheets and thesquare pillars are connected through the bolts. Water storing grooves are formed in the flangings of the n-shaped galvanized steel sheets. The adopted steel wood keel is large in section inertia, highin stress performance, moderate in price and capable of improving corrosion resistance and stability and can be widely applied; the steel-wood-integrally-combined n-shaped steel-wood keel can bring the material characteristic into play to the utmost extent and increase the strength-weight ratio; and nailing is facilitated in formwork erecting through the inlaid square pillars, meanwhile the inlaid square pillars are effectively protected through the peripheral bent n-shaped beam steel sheets, the loss of the square pillars is greatly reduced, the project cost is reduced, and environment protection is achieved.

The invention relates to and discloses a split type leveling screw rod and a using method, and relates to the technical field of architectural decoration. The split type leveling screw rod comprises a base, a first screw rod, a sliding block, a connecting device and a fixing device, wherein the base is fixed to an original wall surface, one end of the first screw rod is rotationally connected with the base, one end of the sliding block is rotationally connected to the other end of the first screw rod, the other end of the sliding block is fixedly connected with a keel, the connecting device is used for rotationally connecting the first screw rod to the base, the fixing device is used for fixing the base to the original wall surface, when the first screw rod rotates on the base, the sliding block rotationally connected to the first screw rod longitudinally moves on the first screw rod and is used for leveling the keel fixed to the sliding block, and a graduated scale is arranged on the first screw rod. According to the split type leveling screw rod, the sliding block longitudinally moves on the first screw rod to drive the height of the keel fixed to the sliding block to change, so that leveling of a wallboard installed on the keel is achieved, the graduated scale is arranged on the first screw rod, the height of the sliding block on the first screw rod can be accurately controlled, and leveling of the installed wallboard is rapidly achieved.

The invention discloses a multi-position drum water drilling, grinding and polishing integrated machine. The integrated machine consists of a base, a fixed lower seat A, a fixed upper seat A, a diamond wheel, a polishing wheel, a fixed lower seat B, a fixed upper seat B, an eccentric wheel rotating step motor, a transmission connecting shaft, an upper water stop shield, a grinding wheel motor, a grinding wheel motor seat, a polishing wheel motor, a polishing wheel motor seat, a rack, a swing motor, a swing motor seat, a swing eccentric piece, a cylinder, a connecting plate A, a connecting plate B, an eccentric wheel step motor seat, a position adjustor, an eccentric wheel, a limit plate, a protective cover chute plate, an organ-type protective cover, a keel pressing plate, an aluminum shuttle seat plate, a transverse linear guide rail, a cushion plate between guide rails, a longitudinal guide rail, a 33-oil tank, a movable baffle plate, a movable baffle seat plate, a lower water stop shield, an aluminum shuttle, a steering mechanism fixed seat, a steering step motor and a shuttle pressing plate accessory. The integrated machine has the advantages that: the step motor is adopted for feeding and steering so that the product has high precision, strong stability and simple adjustment and realizes single-person operation; and the yield of the integrated machine is greater than and even exceeds that of the conventional two-person or three-person machine, the work efficiency is greatly improved, meanwhile, the yield of the product is greatly improved and the waste of raw materials is reduced.

The invention provides a visible rack ceiling which comprises a panel, storage sapwood and a storage mechanism. The storage sapwood is mounted at a side edge of the panel, an overlapping part for overlapping is arranged on the outer side of the storage sapwood, and the storage sapwood is movably connected to the side edge of the panel through the storage mechanism, so that the storage sapwood canprotrude out of or can be stored at the side edge of the panel. The storage sapwood overlapped on a keel can switch a stretching state or a retracting state at the edge of the panel, so that the visible rack ceiling is convenient to mount.

The invention relates to bending equipment, in particular to bending equipment for green light steel keel partition wall building material production. The environment-friendly light steel keel partition wall building material production bending equipment which can bend light steel keel fractures without manual cooperation of people, saves labor and is high in efficiency needs to be designed. Green light steel keel partition wall building material production bending equipment comprises a supporting frame, a fixing block, a mounting column and the like, the fixing block is fixedly connected to the middle of the lower portion of the outer right side face of the supporting frame, and the mounting column is rotationally connected to the right end of the fixing block in a penetrating mode. The light steel keel is placed on the positioning mechanism to be positioned, then the positioning mechanism is pulled to drive the light steel keel to move rightwards to the bending position, the limiting mechanism presses and limits the light steel keel, then a telescopic rod of the hydraulic cylinder is started to extend to drive the pressing block to move upwards, the pressing block moves upwards to bend the light steel keel, and therefore the light steel keel is bent. The light steel keel is bent without manual cooperation, labor is saved, and efficiency is high.
