Description

Technical Field

[0001] The utility model relates to the technical field of protective equipment, in particular to a protective fence used in a construction site. Background Art

[0002] Construction fence refers to a barrier set up around the construction site to protect the construction site from interference and safety. It is usually made of color steel plates, metal plates, plastic plates and other materials, and the height is generally above 1.8 meters. It can prevent people and vehicles from entering the construction site at will and ensure construction safety. Construction fences should be set up around the construction site and should be set up at the specified position and distance to ensure that the construction site can be effectively protected from interference and safety. The materials of the construction fence should be durable, strong, and beautiful, and be able to withstand the test of natural conditions such as wind and rain. At the same time, they must also meet safety requirements such as fire prevention and anti-theft. Obvious signs, warning signs and other signs should be set on the construction fence to remind people to pay attention to safety and civilized construction. The signs should be clear, concise and easy to identify. Most of the existing protective fences are fixed and fixed at the construction site by anchor bolts. Although they can provide better protection, they are cumbersome to dismantle during or after construction, and removing the anchor bolts for fixing will also waste a lot of manpower and financial resources. Utility Model Content

[0003] The purpose of the utility model is to provide a protective fence for a construction site, which only needs to be fixed with sand or other heavy objects when in use, and then the fence is plugged into the anchor seat to quickly form protection, and is easy to install and remove.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a protective fence for a construction site, comprising two or more anchor bases and fences installed on the anchor bases, the fence comprising connecting rods and a protective net that constitute a frame, the protective net being installed between the connecting rods, and the lower ends of the connecting rods on the left and right sides being plugged into the anchor bases, a group of sockets for plugging in the fences are also provided on the anchor bases, and a penetrating connecting hole is also provided in the sockets, two adjacent fences are fixedly connected by a connecting piece, and an identification plate is provided on the fence.

[0005] Furthermore, the anchor seat is an inner hollow structure, and a rectangular notch communicating with the inner hollow structure is also provided on the surface of the anchor seat.

[0006] Furthermore, the connecting piece is composed of two fasteners and bolts that are snap-connected. The middle part of the fastener is a plane, and a screw hole for passing the bolt is opened in the center. The two ends of the fastener are arc-shaped surfaces, which are tightly connected to the connecting piece through the arc-shaped surfaces.

[0007] Furthermore, the connecting hole is concentric with the inserting hole, and the diameter of the connecting hole is smaller than the diameter of the inserting hole.

[0008] Furthermore, the anchor seat is provided with a through rectangular hole, and the inner wall of the rectangular hole is provided with a vertical groove.

[0009] The beneficial effects of the utility model are: 1) the utility model supports the fence by the anchor base, and there is no need to fix the fence by bolts or other fasteners. The fence and the anchor base are plugged in, which is not only convenient and fast, but also can be combined into a protection range of any size and shape. Compared with traditional fences, it can save installation and dismantling time. The anchor base adopts a variety of fixing forms. It can be fixed by injecting sand or negative pressure heavy objects, or it can be fastened by driving ground nails into the connecting holes. It is suitable for fixing in different venues, and the structure is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0015] Embodiment: As shown in the figure, the protective fence for construction sites described in the utility model comprises two or more anchors 1 and fences 2 installed on the anchors 1, the fences 2 comprising connecting rods 3 and protective nets 4 constituting a frame, the protective nets 4 being installed between the connecting rods 3, and the lower ends of the connecting rods 3 on the left and right sides being plugged into the anchors 1, the anchors 1 being further provided with a group of plug holes 5 for plugging the fences 2, the plug holes 5 being further provided with penetrating connecting holes 6, the two adjacent fences 2 being fixedly connected by connecting members 7, and the fences 2 being provided with signboards 8. The signboards 8 can be used to warn passers-by or vehicles at night, when in use, one end of the fence 2 is plugged into the plug hole 5 on one side of the anchor 1, and the other fence 2 is plugged into the plug hole 5 on the other side of the anchor 1, and the two adjacent fences 2 are fastened by the connecting members 7, so that the fences 2 form a whole. And the plug holes 5 on the anchors 1 can make the fences 2 freely combined to form protection ranges of different angles and sizes.

[0016] The anchor base 1 is an inner hollow structure, and a rectangular notch 9 communicating with the inner hollow structure is also provided on the surface of the anchor base 1. Sand or other heavy objects can be poured into the inner hollow structure through the rectangular notch 9 to enhance the overall deadweight of the anchor base 1 and improve the supporting effect.

[0017] The connector 7 is composed of two buckled fasteners 10 and a bolt 11. The middle part of the fastener 10 is a plane, and a screw hole for passing the bolt 11 is opened at the center. The two ends of the fastener 10 are arc-shaped surfaces, which are tightly connected to the connector 7 through the arc-shaped surfaces. Two adjacent fences 2 can be connected together through the fastener 10, and fastened by the bolt 11, so that multiple fences 2 are connected into a whole, improving the structural strength and stability.

[0018] The connection hole 6 is concentric with the insertion hole 5, and the diameter of the connection hole 6 is smaller than that of the insertion hole 5. That is, when in use, the fence 2 can be inserted into the insertion hole 5, and the anchor bolt can be installed in the lower end of the connection hole 6 for fixing. There is a step between the connection hole 6 and the insertion hole 5, that is, the lower end of the insertion hole 5 can be limited by the connection hole 6 to ensure the uniform insertion depth of the fence 2.

[0019] The anchor base 1 is also provided with a through rectangular hole 12, and the inner wall of the rectangular hole 12 is provided with a vertical groove 13. When in use, the rectangular hole 12 is used to install a ground nail or other supporting member connected to the ground, and can also be used to plug in a square or special-shaped connecting rod 3 to warn passers-by. At the same time, the groove 13 in the hole can increase friction and improve the plug-in effect.

[0020] The utility model supports the fence by the anchor base, and there is no need to fix the fence by bolts or other fasteners. The fence and the anchor base are plugged in, which is not only convenient and quick, but also can be combined into a protection range of any size and shape. Compared with traditional fences, it can save installation and dismantling time. The anchor base adopts a variety of fixing forms, and can be fixed by injecting sand or negative pressure heavy objects, or by driving ground nails into the connecting holes for fastening. It is suitable for fixing in different venues, and has a simple structure and is easy to use.

[0021] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
