Description

Technical Field

[0001] The utility model relates to the technical field of steel structure supporting devices, in particular to a steel structure unloading sand box. Background Art

[0002] Temporary support for steel structures is an indispensable part of building construction and maintenance. Temporary support is used to support heavy objects such as concrete and steel beams at the construction site to ensure safety and stability during construction. Sand boxes, as a commonly used temporary support tool, are widely used in the fields of construction and engineering.

[0003] However, there are some problems with traditional sand boxes during use. First, due to material and structural limitations, the load-bearing capacity of traditional sand boxes is limited and cannot meet the temporary support requirements in some special occasions. Secondly, when unloading, traditional sand boxes discharge sand through a sand discharge valve. The sand discharge valve is generally set slightly tilted to help discharge sand. The tilted surface only exists inside the sand discharge valve and has a limited range, resulting in a slow sand discharge speed and reduced work efficiency. Utility Model Content

[0026] A removable sand box for temporary support of a steel structure, comprising a sleeve and a piston. The specific structural features of the sand box are as follows:

[0027] Sleeve: The upper end of the sleeve is open. A partition is installed inside the sleeve to divide the interior of the sand box into an upper cavity and a lower cavity; a reinforcing ring plate is fixed on the outer wall of the sleeve, and reinforcing ribs are added to enhance the bearing capacity of the sleeve.

[0028] Piston: The piston is mounted inside the sleeve, directly above the partition. There are scale markings on the outer wall of the piston to read the amount of piston settlement.

[0029] Partition: A funnel-shaped through hole is provided in the center of the partition, which connects the upper cavity and the lower cavity. The upper cavity and the lower cavity are filled with fine sand. The main function of the partition is to separate the upper cavity and the lower cavity. The funnel-shaped through hole is provided, and the slope is increased, which is conducive to the rapid sliding of the fine sand, so that the fine sand can quickly pass through the funnel-shaped through hole into the lower cavity.

[0030] Lower cavity: The bottom of the lower cavity is provided with an inverted funnel-shaped protrusion, and the side wall is provided with multiple sand discharge valves. The inverted funnel-shaped protrusion increases the slope, which can make the fine sand flow quickly from the center to the two sides, and finally be discharged quickly from the sand discharge valve.

[0031] When using this unloadable sand box, first transport the sand box to the required construction site and position it at the required location through temporary support. After the permanent support is completed, the sand box is unloaded and taken out. When unloading, open the sand discharge valve to remove the fine sand in the sand box, and then the piston descends. After it descends below the permanent support, the sand box can be disassembled and transported back, waiting for the next use.

[0032] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
