Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction, and in particular to a protective device for a formwork material transfer port. Background Technology
[0002] Aluminum alloy formwork is mostly used in building construction. Aluminum alloy formwork has high strength and good stability. Because it is made of standard extruded profiles, the components often have high strength, stability and rigidity, and are very sturdy during use. Because it is easy to assemble and each piece weighs less than 30 kg, it can be manually transferred and spliced without the limitations of machinery, so efficiency can be significantly improved and it is widely used.
[0003] When using aluminum alloy formwork, 2-4 200*800mm material transfer ports are set on each floor's top slab for transferring material between the upper and lower layers of the aluminum alloy formwork. After construction is completed, the ports are sealed with concrete. However, in most cases at construction sites, bamboo plywood or iron plates are used as covers to cover the material transfer ports to prevent people from falling. In order to transfer the formwork, the covers are often opened, resulting in the covers being moved frequently, not being put back in time, or being lost, causing significant safety hazards on site. Utility Model Content
[0004] The purpose of this utility model is to provide a template material conveying port protection device that is simple in structure, easy to install, can block and protect the material conveying port, is not easy to lose, and can be repeatedly installed and used.
[0005] This utility model is achieved through the following measures:
[0006] A protective device for a template feed port, characterized in that it includes a mounting frame and a rotating cover plate disposed on the mounting frame;
[0007] The mounting frame includes a rectangular frame, which is disposed on a protrusion inside the feed inlet;
[0008] The rectangular frame has several rectangular slots on the inner side of both sides of the frame in the width direction, and a U-shaped limiting frame is installed in the rectangular slot;
[0009] One end of the U-shaped limiting frame is inserted into the rectangular slot, and the other end of the rectangular slot is located below the building floor slab.
[0010] A mounting crossbar is bolted to one side of the rectangular frame in the width direction, and the rotating cover plate is mounted on the mounting crossbar.
[0011] The specific features of this utility model also include:
[0012] The rotating cover plate is mounted on the mounting crossbar via a hinge, and the free end of the rotating cover plate rests against the building floor slab.
[0013] The U-shaped limiting frame is installed on the side plate below the building floor slab and has a through threaded hole. A limiting bolt is installed in the threaded hole, and the end of the limiting bolt passes through the threaded hole and abuts against the building floor slab.
[0014] The width of the rotating cover is greater than the width of the feed inlet.
[0015] During installation, the rectangular frame is placed on the protrusion inside the material inlet. Then, one end of the U-shaped limiting bracket is inserted into the rectangular slot. Next, the U-shaped limiting bracket is placed close to the material outlet, and the limiting bolts at the bottom of the U-shaped limiting bracket are tightened so that the limiting bolts abut against the building floor slab, thus completing the installation of the rectangular frame. Finally, the installation crossbar is assembled onto the rectangular frame to complete the installation.
[0016] When conveying the aluminum template, simply open the rotating cover plate.
[0017] The advantages of this utility model are: simple structure and convenient installation. On the one hand, it can block and protect the material conveying port and prevent it from being lost. On the other hand, it can be installed and used repeatedly. Attached Figure Description
