Description

Technical Field

[0001] This utility model relates to a device for collecting steel bar waste at construction sites, which is a device for collecting steel bar waste at construction sites. Background Technology

[0002] Construction processes typically generate a large amount of steel reinforcement waste. To facilitate centralized processing of this waste, steel reinforcement waste collection pools are usually set up at construction sites to collect it.

[0003] Traditional steel rebar waste pits are generally brick masonry structures. Construction requires setting out lines and laying bricks, using materials such as bricks, sand, and cement. The exterior of the walls also needs to be plastered and painted. The process is complicated, time-consuming, and labor-intensive. Moreover, the location of the steel rebar waste pit cannot be moved during construction. However, the location of the steel rebar shed will be adjusted from the foundation construction stage to the main construction stage, requiring the steel rebar waste pit to be rebuilt and the original steel rebar waste pit to be demolished. This is not only time-consuming and labor-intensive, but also incurs high costs for transporting the waste after demolition.

[0004] Currently, steel-shaped waste pits are also used to collect steel rebar waste. However, existing steel-shaped waste pits have drawbacks such as not being able to be quickly disassembled, occupying a large space, and being inconvenient to store and transport after use. Utility Model Content

[0005] To address the aforementioned shortcomings in the existing technology, this utility model provides a construction site steel reinforcement waste collection device that features high structural strength, quick assembly and disassembly, easy storage, and convenient transportation.

[0006] This utility model is achieved through the following technical solution: a construction site steel reinforcement waste collection device, characterized in that: it includes a rectangular base plate, a rectangular front baffle plate set at the front end of the base plate, a rectangular rear baffle plate set at the rear end of the base plate, and two side baffle plates set on the left and right sides of the base plate. The height of the front baffle plate is less than the height of the rear baffle plate. The bottom of the two side baffle plates are respectively hinged to the left and right sides of the base plate. The front end of the front baffle plate is connected to the front end of the two side baffle plates by a pin. The rear end of the rear baffle plate is connected to the rear end of the two side baffle plates by a pin. U-shaped lifting lugs are fixed on both side baffle plates. The base plate, front baffle plate, rear baffle plate, and side baffle plates all include a square tube frame welded from 40*80mm Q235 square tubes. A 5mm thick steel plate is fixed on the inner side of the square tube frame.

[0007] In this invention, the front and rear baffles are connected to the side baffles by pins, enabling quick installation and disassembly of the device. Installation and disassembly are simple, convenient, and fast, and the pins on the front and rear baffles are easy to open, facilitating the handling of steel scrap inside the device. The side baffles are hinged to the bottom plate, and the two side baffles can be folded. When the device is not in use, the front and rear baffles can be removed, and the two side baffles can be folded onto the bottom plate, reducing the device's footprint and facilitating storage and transportation. The device can be moved by lifting the U-shaped lugs on the side baffles. When the device needs to be repositioned during construction, lifting equipment can be used to lift the device by the U-shaped lugs and transfer it to the new steel processing area.

[0008] Furthermore, to ensure the reliability of hoisting, the U-shaped lifting lug is a long-arm lifting lug made of steel bars. The two long arms of the U-shaped lifting lug extend to the bottom of the side baffle and are welded together with the square tube of the side baffle.

[0009] Furthermore, each side panel is provided with two U-shaped lifting lugs at intervals.

[0010] Furthermore, to ensure reliable connection between the baffles, the upper and lower ends of the front and rear baffles are equipped with pins to connect with the upper and lower ends of the side baffles on both sides.

[0011] Furthermore, to facilitate folding and storage, the height of the side panels should not exceed 1 / 2 the length between the left and right sides of the base plate.

[0012] The beneficial effects of this utility model are as follows: This utility model has a simple structure. The front baffle, rear baffle, and side baffles on both sides are connected by pins, enabling quick installation and disassembly of the device. This flexible installation and disassembly improves the flexibility of the rebar waste collection device. Furthermore, the pins on the front and rear baffles are easy to open, facilitating the dumping of rebar waste inside the device and enabling rapid loading, unloading, and transportation of rebar waste, thus saving manpower. The side baffles on both sides are hinged to the bottom plate. When the device is not in use, the front and rear baffles can be removed, and the two side baffles can be folded onto the bottom plate, reducing the device's footprint and facilitating storage and transportation. The bottom plate, front baffle, rear baffle, and side baffles are all made of 40*80mm square tubing and steel plate, resulting in high structural strength, good load-bearing capacity, resistance to damage, and a long service life. This utility model is reusable and has a high turnover rate. Attached Figure Description

[0020] The present invention will be further described below through non-limiting embodiments and in conjunction with the accompanying drawings:

[0021] As shown in the attached diagram, a construction site rebar waste collection device includes a base plate 1, a front baffle 2 located at the front end of the base plate 1, two side baffles 3 located on the left and right sides of the base plate 1, and a rear baffle 4 located at the rear end of the base plate 1. The base plate 1, front baffle 2, and rear baffle 4 are all rectangular plate structures, each using a square tube frame lined with steel plates. The square tube frame is welded from 40*80mm Q235 square tubes, and the inner steel plate is 5mm thick. The bottoms of the two side baffles 3 are hinged to the left and right sides of the base plate 1, respectively. The front baffle 2 is connected to the front ends of the two side baffles 3 via pins 6, and the rear baffle 4 is connected to the rear ends of the two side baffles 3 via pins 6. U-shaped lifting lugs 5 are fixed to both side baffles 3.

[0022] In this embodiment, the base plate 1 has a size of 3m*2.1m. The base plate 1 includes a rectangular square tube frame 1.1 welded from 40*80mm Q235 square tubes. Multiple horizontal and vertical braces are welded inside the rectangular frame of the square tube frame 1.1 for reinforcement. Both horizontal and vertical braces are also made of 40*80mm Q235 square tubes. An inner steel plate 1.2 is welded and fixed to the inner side of the square tube frame 1.1. Two hinges 7 are connected to the left and right sides of the base plate 1. The front baffle 2 has a size of 3m*1m. The front baffle 2 includes a rectangular square tube frame 2.1 welded from 40*80mm Q235 square tubes. Multiple square tube vertical braces are welded inside the rectangular frame of the square tube frame 2.1 for reinforcement. An inner steel plate 2.2 is welded and fixed to the inner side of the square tube frame 2.1. A pin rod 6.1 is fixed at each of the four outer corners of the front baffle 2. The rear baffle 4 has dimensions of 3m x 1.5m. It includes a rectangular square tube frame 4.1 welded from 40*80mm Q235 square tubing. Multiple square tube vertical supports are welded inside the rectangular frame 4.1 for reinforcement. An inner steel plate 4.2 is welded and fixed to the inner side of the square tube frame 4.1. A pin rod 6.1 is also fixed at each of the four outer corners of the rear baffle 4. The left and right side baffles 3 have identical structures. Each side baffle 3 is a right-angled trapezoid with dimensions of 2.1m in length, 1m in front height, and 1.5m in rear height. It also includes a square tube frame 3.1 welded from 40*80mm Q235 square tubing. An inner steel plate 3.2 is welded and fixed to the inner side of the square tube frame 3.1.
