The invention discloses a prefabricated building combined adjustable supporting frame. The prefabricated building combined adjustable supporting frame comprises threaded rods, an upper supporting plate and a lower supporting plate, wherein the upper supporting plate is fixedly connected with the lower supporting plate through threaded sleeves, the outer surface walls of the junctions between the threaded sleeves and the upper supporting plates and junctions between the threaded sleeves and the lower supporting plates are sleeved with fastening rubber rings respectively, the centers of the threaded sleeves are in threaded connection with the threaded rods, the top ends of the threaded rods are sleeved with bearings, the bearings are embedded in the lower surface wall of a transition plate,the upper end of the transition plate is in threaded connection with a top plate through long bolts, the two long side edges of the lower supporting plate are fixedly provided with fixing columns, rotating shafts are inserted in the centers of the fixing columns, and the outer surface walls of the rotating shafts are sleeved with movable baffles. The prefabricated building combined adjustable supporting frame has the advantages that the purpose of adjusting the height of the supporting frame is achieved through the engagement of the threaded rods and circular gears, and the supporting frame isfastened by using fastening bolts when adjusted to the required height, so that the use safety of the supporting frame is improved, the operation is simple, time and labor are saved, and the prefabricated building combined adjustable supporting frame meets the construction requirements.

The invention discloses a sand screening device which comprises a tank body, a screen net and a power device; the tank body comprises a sand inlet cabin and a power chamber; the upper end and the lower end of the sand inlet cabin are of an opening structure; a cleaning hole is formed in one side of the sand inlet cabin and is provided with a cleaning cover; the cleaning cover is provided with a cover lock; the screen net is arranged in the sand inlet cabin and is of a semicircular cylinder structure; the two ends of the screen net are connected with the inner wall of the sand inlet cabin; thepower device is arranged in the power chamber; the inner wall, adjacent to the sand inlet cabin, of the power chamber is provided with a rotary table; one side of the rotary table is connected with the screen net; the other side of the rotary table is connected with the power device; and the power device is connected with the upper inner wall and the lower inner wall of the power chamber.

A concrete pouring hopper for building construction, the invention relates to the technical field of construction equipment; the four corners of the upper surface of the base are connected with uprights, and the tops of the uprights are connected and fixed with the four corners of the top plate; There are horizontal plates connected between them; a hopper is arranged between the horizontal plates on the left and right sides, and the hopper rotating shaft is fixed on the left and right side walls of the hopper, and the outer ends of the hopper rotating shafts on the left and right sides are respectively screwed to the left and right sides through bearings. Among the horizontal plates on both sides, the outer end of the hopper rotating shaft on the left passes through the left horizontal plate, and is connected and fixed with the rotating handle. A positioning pin is inserted on the rotating handle, and the inner end of the positioning pin is detachable. Inserted in the left cross plate. Its discharge can be adjusted, which greatly increases its scope of application and meets the needs of multi-structure buildings. At the same time, it can also facilitate cleaning, improve construction progress, and have stronger practicability.

The invention relates to a detachable prefabricated wall mold. The detachable prefabricated wall mold comprises a first module, a second module, a third module and a fourth module which are assembledtogether through positioning pins and bolts, and fixed on a workbench so as to form the detachable prefabricated wall mold, wherein a crack is left among the first, second, third and fourth modules after the assembly; a water-stop steel plate is mounted in the crack; through three positioning blocks welded onto the third module, the first, second, third and fourth modules are positioned and connected with the water-stop steel plate; each of the first, second, third and fourth modules is formed by welding an upper horizontal plate, a lower horizontal plate and rib plates arranged on two sides;and reinforcing rib plates are welded into the second and third modules along the vertical direction. By adoption of the detachable prefabricated wall mold provided by the invention, the constructionrequirements for various wall length specifications can be met; the problem that the length of a conventional mold can be modified only through cutting can be solved; a lot of steel and manpower can be saved; the construction period can be shortened; and greater economic benefits can be achieved.
