Problems solved by technology
[0003] 1. Affected by long-term traditional buildings, the precision error of concrete components is generally large, and it is difficult to maintain and repair later
2. The assembly time of general molds is long and the degree of automation is low. Technical workers who have not passed the construction inspection cannot complete accurate installation and disassembly
3. The installation and disassembly of the general mold requires a large crane to complete, and there are safety hazards in the operation
4. Now the cost of traditional prefabricated molds is too high for a set of molds, and it takes up a lot of work space

The invention discloses a horizontal side-turning adjustable precast stair mold. The mold comprises a bottom mold, a plurality of side molds and an end mold and further comprises a base. The end mold and the plurality of the side molds are mounted on the bottom mold to form a mold component. The base is in a groove structure, a hydraulic driving unit is arranged on the bottom of the inside of the base, and the end of one side wall of the base is movably connected with a turning mechanism through a turning shaft. An ejection rod of the hydraulic driving unit is movably connected with the bottom side of the turning mechanism, and pulley guide units for limiting sliding of the side molds in the horizontal direction are mounted above the turning mechanism. Adjusting units for adjusting the distances among the plurality of the side molds are arranged above the turning mechanism. Ports movably connected with drawing shafts of the adjusting units are formed in the lower ends of the side molds, and the side molds and the side mold top ends are fixed through screws. The mold has the advantages that the mold adjusting units can perform mold size adjustment, and the mold side turning unit can perform side turning after member pouring, accordingly, de-molding is facilitated.
Description
technical field [0001] The invention relates to a mold, in particular to a horizontal rollover adjustable prefabricated stair mold. Background technique [0002] Prefabricated buildings are a new type of construction method that has been widely advocated in China's construction industry in recent years. The government is now focusing on promoting and advocating this prefabricated construction method throughout the country. This new construction method is to split the house design into individual cement components, such as wall panels, stairs, balconies, etc. After fabrication in the factory, the individual components are transported to the building site for assembly. Among them, the concrete prefabricated stairs are also made by steel precision molds. The conventional steel precision stair mold is composed of several major elements: the bottom film, the side mold, the end mold, the middle adjustment device, the guide device and the powertrain. Disadvantages of the existin...
