Description

Technical Field

[0001] The utility model belongs to the technical field of construction sites, and particularly relates to a safety fence for construction sites. Background Art

[0002] A construction site, also known as a building site or construction site, or simply a site, is a location where a construction project or civil engineering work is underway. It's often enclosed by fences, wire mesh, or walls, restricting the entry and exit of personnel, materials, machinery, and vehicles. Before entering a construction site, construction workers must undergo training and assessment on construction safety and fire safety.

[0003] Before construction begins, a safety fence is needed to enclose the construction site. The purpose of the fence is to prevent outsiders from entering the construction site and causing unnecessary trouble. This can not only ensure the smooth progress of construction work, but also prevent outsiders who do not understand construction from having physical safety problems.

[0004] The existing safety fence cannot be adaptively adjusted in height as a whole, and the overall height is fixed in design, so it cannot meet the actual construction needs. In addition, the safety fence is directly placed on the ground at the construction site, lacking an effective safe and stable fixing mechanism, and has poor stability and is easy to be accidentally knocked over. For this reason, we propose a safety fence for construction sites. Utility Model Content

[0005] The purpose of the present utility model is to provide a safety fence for construction sites, so as to solve the problem proposed in the above-mentioned background technology that the existing safety fence as a whole cannot be adaptively adjusted in height and the overall height is fixed in design, so it cannot meet the actual construction needs, and the safety fences are directly placed on the ground at the construction site, lack an effective safe and stable fixing mechanism, have poor stability, and are easy to be accidentally knocked over.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a safety fence for a construction site, comprising a lower guardrail, a middle guardrail and an upper guardrail, wherein the lower guardrail, the middle guardrail and the upper guardrail are arranged in sequence from bottom to top, a plurality of lower guard plates are fixedly installed between the lower guardrail and the middle guardrail, a plurality of upper guard plates are fixedly installed between the middle guardrail and the upper guardrail, the upper guard plate is slidably installed on the middle guardrail, a sliding frame is fixedly installed on the bottom end of the upper guard plate, and the sliding frame is slidably installed on the outer surface of the lower guard plate at the same side position, A locking rod is slidably installed on the sliding frame, and an operating panel is fixedly installed on one end of the locking rod. Several locking slots are provided on the side of the lower guard plate, and the other end of the locking rod cooperates with the locking slot. Two stabilizing plates are rotatably installed on both ends of the lower guard plate, and several ground nails are inserted on the stabilizing plates. A sliding block is slidably installed on the side of the lower guard plate, and a positioning rod is fixedly installed on the side of the sliding block. A positioning slot for inserting the positioning rod is provided on the end of the stabilizing plate, and a water pipe is detachably installed on the upper surface of the upper guard plate, and several nozzles are installed on the water pipe.

[0007] The above scheme is adopted, by setting the lower guard plate, the middle guard plate and the upper guard plate in conjunction with the lower guard plate, the lower guard plate can slide up and down on the middle guard plate and be locked in position with the locking rod, so that the height can be selectively adjusted according to the actual construction needs. The operation and adjustment are convenient, and the universality of use is improved. By setting the stabilizing plate in conjunction with the ground nails, the stabilizing plate can be unfolded when needed and driven into the ground with the ground nails to ensure good stability in use and effectively prevent tipping. When not in use, the stabilizing plate can be folded up and locked with the positioning rod, and the detachable water pipe can be used to choose whether to spray water to reduce dust and temperature during construction, providing a variety of options.

[0008] As a preferred embodiment, a limiting ring is provided inside the sliding frame, the limiting ring is fixedly mounted on the outer surface of the locking rod, and a spring 1 is fixedly mounted between the limiting ring and the inner wall of the sliding frame.

[0009] By adopting the above scheme, the setting of the limit ring can play a limiting effect, preventing the lock rod from disengaging from the sliding frame when sliding. When the lock rod slides out of the lock slot, the spring will deform for a while, so the elasticity of the spring can be used to drive the lock rod to be quickly inserted into the lock slot, thereby improving the convenience of operation.

[0010] As a preferred embodiment, a rotating block is fixedly installed on the end of the stabilizing plate, a fixed block is rotatably installed on the rotating block, and the fixed block is fixedly installed on the end of the lower guardrail.

[0011] By adopting the above solution, the rotational expansion and closing of the stabilizing plate can be realized by cooperating with the rotating block and the fixed block. The structure is simple and the rotation operation is convenient.

[0012] As a preferred embodiment, a trapezoidal slider is fixedly installed on the side of the sliding block, a trapezoidal slide groove is opened on the side of the lower guardrail, a second spring is fixedly installed on the side of the trapezoidal slider, the trapezoidal slider is slidably installed on the inner wall of the trapezoidal slide groove, and the second spring is fixedly installed on the inner wall of the trapezoidal slide groove.

[0013] By adopting the above solution, a trapezoidal slider is used in a trapezoidal slide groove, which can ensure that the sliding block has good stability when sliding and will not detach from the lower guardrail. The elastic force of spring 2 can drive the sliding block to drive the positioning rod to quickly insert into the positioning groove, thereby realizing a convenient locking operation of the stabilizing plate.

[0014] As a preferred embodiment, assembly plates are fixedly installed at both ends of the upper railing, and the two assembly plates are staggered with each other, one above and one below. Assembly sockets are provided on the assembly plates, and an assembly pin is inserted into the assembly socket on one of the assembly plates.

[0015] By adopting the above solution and using the assembly plate in conjunction with the assembly pin, the locking of two adjacent upper guardrails can be strengthened during assembly, thereby improving the overall stability of use.

[0016] As a preferred embodiment, mounting seats are fixedly installed on the outer surfaces of both ends of the water pipe, mounting bolts are threadedly installed on the mounting seats, and mounting thread grooves for screwing the mounting bolts are opened on the upper surface of the upper baffle.

[0017] By adopting the above solution and using the mounting base and mounting bolts together, the water pipe can be conveniently installed, and then the user can choose whether to install the water pipe according to actual construction needs, thereby improving the diversity and selectivity of use.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The safety fence for construction sites is used by setting a lower guard plate, a middle guard plate, and an upper guard plate in conjunction with the lower guard plate and the upper guard plate. The lower guard plate can slide up and down on the middle guard plate and be locked in position by a locking rod, so that the height can be selectively adjusted according to actual construction needs. The operation and adjustment are convenient, and the universality of use is improved.

[0020] The safety fence for construction sites is equipped with stabilizing plates and used with ground nails. When needed, the stabilizing plates are unfolded and driven into the ground with the ground nails to ensure good stability in use and effectively prevent tipping. When not in use, the stabilizing plates can be folded up and locked with the positioning rods. The detachable water pipes can be used to choose whether to spray water to reduce dust and temperature during construction, providing a variety of options. BRIEF DESCRIPTION OF THE DRAWINGS

The sliding frame 6 is slidably installed on the outer surface of the lower guard plate 4 at the same side position. There is a locking rod 7, one end of which is fixedly installed with an operating panel 8, and a number of locking slots are provided on the side of the lower guard plate 4. The other end of the locking rod 7 cooperates with the locking slot. Two stabilizing plates 9 are rotatably installed at both ends of the lower guard plate 1, and a number of ground nails 10 are inserted on the stabilizing plates 9. A sliding block 11 is slidably installed on the side of the lower guard plate 1, and a positioning rod 12 is fixedly installed on the side of the sliding block 11. A positioning slot for inserting the positioning rod 12 is provided at the end of the stabilizing plate 9, and a water pipe 13 is detachably installed on the upper surface of the upper guard plate 3, and a number of nozzles 14 are installed on the water pipe 13.

[0027] By setting the lower guard plate 1, the middle guard plate 2, and the upper guard plate 3 for use in conjunction with the lower guard plate 4 and the upper guard plate 5, the lower guard plate 4 can slide up and down on the middle guard plate 2 and be locked in position using the locking rod 7, so that the height can be selectively adjusted according to the actual construction needs. The operation and adjustment are convenient, and the universality of use is improved. By setting the stabilizing plate 9 for use in conjunction with the ground nails 10, the stabilizing plate 9 can be unfolded when needed and driven into the ground with the ground nails 10 to ensure good stability in use and effectively prevent tipping. When not in use, the stabilizing plate 9 can be folded up and locked with the positioning rod 12, and the detachable water pipe 13 can be used to choose whether to spray water to reduce dust and temperature during construction, providing a variety of options.

[0028] A limit ring 15 is provided inside the sliding frame 6, and the limit ring 15 is fixedly installed on the outer surface of the locking rod 7. A spring 16 is fixedly installed between the limit ring 15 and the inner wall of the sliding frame 6. The setting of the limit ring 15 can play a limiting effect to prevent the locking rod 7 from separating from the sliding frame 6 when sliding. When the locking rod 7 slides out of the lock slot, the spring 16 will be deformed. Therefore, the elasticity of the spring 16 can be used to drive the locking rod 7 to be quickly inserted into the lock slot, thereby improving the convenience of operation.

[0029] A rotating block 18 is fixedly installed at the end of the stabilizing plate 9, and a fixed block 17 is rotatably installed on the rotating block 18.
