Description

Sand screening net for constructional engineering

Technical Field

The utility model belongs to the technical field of building engineering, especially, relate to a screening sand net that building engineering used.

Background

In the building engineering work progress, often can use the sand, and before using the sand, need use the screening sand device to sieve the sand operation, the screening sand machine kind that has now on the market is various, and is multiple functional, however, to the less construction team of some scales, the screening sand machine is with high costs, and carries inconveniently, still traditional screening sand net of often used.

Traditional screening sand net includes a frame, installs the screen cloth in the frame, is provided with two bracing pieces on the frame, supports screening sand net slope on the building site, and the workman is with the spade with sand to screening sand net shed and sieve sand.

The above-mentioned conventional sand screen has the following problems: because the sand screening net is obliquely arranged, workers need to throw sand to a high place by using large strength, so that the sand screening work is completed in the falling process, and the labor is wasted; the lower end of the sand screening net is closer to the ground, so that the lower part of the sand screening net is easily contacted with screened sand, the subsequent sand screening is not facilitated, and the sand at the lower end of the sand screening net is often required to be cleaned; because sand is great to the impact force of screen cloth, often can lead to the screen cloth middle part concave down, influence the life of screen cloth.

Disclosure of Invention

In order to solve the above problem, the utility model adopts the technical scheme that:

a sand screening net for constructional engineering comprises an outer frame and a baffle, wherein the outer frame is a rectangular outer frame formed by four frames, the inner sides of the four edges of the outer frame are fixedly connected with a screen, four corners of the outer frame are respectively connected with a retractable supporting leg, the upper surface of one edge of the outer frame is provided with a rectangular mounting hole, the baffle is of a convex structure, the width of the narrow end of the baffle is equal to the length of the mounting hole, and the narrow end of the baffle is detachably mounted in the mounting hole; the below of screen cloth is provided with the reinforcing bar of a plurality of crisscross settings, and reinforcing bar fixed mounting is on the frame of frame, and reinforcing bar and screen cloth laminating set up.

In a further improvement, the supporting legs are connected with the corners of the outer frame through hinges.

In a further improvement, a handle is respectively arranged in the middle of the lower surfaces of two edges of the outer frame adjacent to the edge provided with the mounting hole.

In a further improvement, the screen is made of stainless steel.

In a further improvement, the baffle is made of aluminum alloy.

In a further improvement, the length of the supporting leg is less than half of the length of the outer frame.

Since the technical scheme is used, the utility model discloses the beneficial effect who gains does:

the utility model is provided with four foldable and unfoldable supporting legs, the sand screening net can be horizontally supported on the bottom surface, and workers only need to throw sand onto the sand screening net, thereby reducing the sand throwing height and saving strength; the height of the whole screen from the bottom surface is consistent, so that the situation that sand behind the screen needs to be cleaned frequently is avoided, and when the tip of the sand pile is higher, the sand pile only needs to be flatly shoveled by a shovel; the reinforcing steel bars are arranged, so that the phenomenon that the screen mesh is sunken due to sand impacting the screen mesh can be prevented, and the service life of the screen mesh is prolonged; the baffle is arranged, so that sand can be prevented from being thrown out of the range of the screen due to excessive force when workers throw sand; still be provided with the handle, the convenient transport to screening sand net.
