Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction equipment, and more specifically to a safety enclosure for construction. Background Technology
[0002] Gas pipelines need to be excavated and inspected regularly. Currently, these pipelines are buried quite deep, so after excavation, safety barriers need to be erected to prevent soil and rocks from sliding down the sides of the inspection pit. This effectively ensures the safety of inspection personnel and prevents damage to the gas pipelines during the inspection process.
[0003] The existing safety barriers are constructed using steel pipes and composite panels. Several steel pipes are assembled into a frame to enclose the gas pipeline, and composite panels are placed between the frame and the mud pit to ensure the safety and stability of the inspection location. However, building a frame with steel pipes requires fixing the pipes together in pairs, resulting in low assembly and disassembly efficiency. Furthermore, the relatively smooth outer surface of the steel pipes makes the structure with clamps weak in terms of structural strength. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a construction safety fence to solve the above-mentioned technical problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a construction safety enclosure, comprising several uprights, horizontal bars, and baffles.

The first upper hanging ear and the first lower hanging ear are positioned correspondingly, and the second upper hanging ear and the second lower hanging ear are positioned correspondingly. The horizontal bars are provided with slots, and the horizontal bars are assembled with the uprights by wrapping the hanging ears with the slots.
[0006] As a further improvement of this utility model, the crossbar is provided with positioning rods, the positioning rods are spaced apart, the distance between adjacent positioning rods is equal to the width of the baffle, the lower end of the baffle is provided with an insertion notch, and the upper side is provided with a connecting hole, the insertion notch covers the positioning rod on the lower crossbar, and the connecting hole covers the positioning rod on the upper crossbar.
[0007] As a further improvement of this utility model, the positioning rod is provided with a positioning recess, the width of which is equal to the thickness of the baffle.
[0008] As a further improvement of this utility model, the heights of the first upper hanging ear and the second upper hanging ear are staggered vertically, and the heights of the first lower hanging ear and the second lower hanging ear are staggered vertically.
[0009] As a further improvement of this utility model, the lower end of the upright is provided with a sharp insertion part.
[0010] As a further improvement of this utility model, the crossbar includes a first rod and a second rod, the first rod is provided with a connecting groove, and the second rod is threadedly connected to the connecting groove.
[0011] As a further improvement of this utility model, the card slot is provided in several places, which are spaced apart.
[0012] The advantages of this utility model are that the horizontal bar and the vertical bar are assembled by interlocking with each other through the slot and the lug, resulting in high horizontal structural strength and stability. Furthermore, no tools are required for assembly, making the assembly process convenient and efficient. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.
[0016] Reference Figure 1 — Figure 5 As shown, a construction safety enclosure according to this embodiment includes several uprights 1, horizontal bars 2, and baffles 3. The uprights 1 are provided with hanging ears on their sides. The hanging ears include a first upper hanging ear 11, a second upper hanging ear 12, a first lower hanging ear 13, and a second lower hanging ear 14. The first upper hanging ear 11 and the first lower hanging ear 13 are positioned correspondingly, and the second upper hanging ear 12 and the second lower hanging ear 14 are positioned correspondingly. The horizontal bars 2 are provided with slots 21. The horizontal bars 2 are assembled with the uprights 1 by wrapping the hanging ears with the slots 21.
[0017] Using the above technical solution, before excavating the gas pipeline for maintenance, a safety enclosure is first erected in the pit. The specific erection process is as follows: four uprights 1 are placed at the four corners of the pit, and the angles of the uprights 1 are adjusted so that the first upper hanging ear 11, the second upper hanging ear 12, the first lower hanging ear 13, and the second lower hanging ear 14 are on the outside. Then, the horizontal bar 2 is moved so that the slot 21 on one side of the horizontal bar 2 is aligned with the first lower hanging ear 13 / second lower hanging ear 14. Then, the slot 21 on the other side of the horizontal bar 2 is aligned with the first lower hanging ear 13 / second lower hanging ear 14 on another upright, thus completing the assembly of one horizontal bar 2. The above operation is repeated to assemble the horizontal bars 2 from bottom to top. After the horizontal bars 2 are assembled, the baffle 3 is placed in the pit. The baffle 3 is located between the outside of the frame and the pit wall. At this time, the construction of the safety enclosure is completed. The horizontal bars 2 and the uprights 1 are connected by the slot 21 and the hanging ear to complete the assembly. The horizontal structure has high strength and stability, and no tools are required during assembly, making the assembly process convenient and efficient.
[0018] When dismantling the safety enclosure of this application, first remove the baffle 3 between the outer sides of the pit wall frame, then lift the horizontal bar 2 upwards to separate the slot 21 from the hanging ear and remove it. Finally, remove the upright 1 for backfilling. No tools are required for dismantling, and the dismantling process is convenient and efficient.
[0019] As an improved specific implementation, the crossbar 2 is provided with positioning rods 22, the positioning rods 22 are spaced apart, the distance between adjacent positioning rods 22 is equal to the width of the baffle 3, the lower end of the baffle 3 is provided with an insertion notch 31, and the upper side is provided with a connecting hole 32, the insertion notch 31 covers the positioning rods 22 on the lower crossbar 2, and the connecting hole 32 covers the positioning rods 22 on the upper crossbar 2.
[0020] Using the above technical solution, when inserting the baffle 3 between the frame and the pit wall, align the insertion notch 31 on the lower side of the baffle 3 with the positioning rod 22 on the lower crossbar 2, and then continue to lower the baffle 3 until the connecting hole 32 and the positioning rod 22 on the upper crossbar 2 are at the same horizontal height. At this point, push it towards the crossbar 2, and the positioning rod 22 will insert into the connecting hole 32, thus completing the assembly of one baffle 3. For disassembly, push the baffle 3 away from the frame to separate the positioning rod 22 from the connecting hole 32, and then pull it upwards.
[0021] The insertion notch 31 and the connecting hole 32 are set in the middle position of the baffle 3. The distance between adjacent positioning rods 22 is equal to the width of the baffle 3. After the baffle 3 is assembled, the position is stable and there is no gap between adjacent baffles 3, which can better protect the maintenance personnel and gas pipelines inside the enclosure.
[0022] With the above structure, after the baffle 3 is assembled, the positioning rod 22 applies downward pressure to the crossbar 2, thereby improving the stability of the enclosure after assembly.
[0023] As an improved specific implementation, the positioning rod 22 is provided with a positioning recess 221, the width of which is equal to the thickness of the baffle 3.
[0024] Through the above technical solution, a positioning recess 221 is provided on the upper side of the positioning rod 22. When the baffle 3 is connected to the positioning rod 22, part of the baffle 3 is embedded in the positioning recess 221 to prevent the baffle 3 from slipping, which can better protect the maintenance personnel and gas pipelines inside the enclosure.
[0025] As one specific implementation of the improvement, the first upper hanging ear 11 and the second upper hanging ear 12 are vertically misaligned, and the first lower hanging ear 13 and the second lower hanging ear 14 are vertically misaligned.
[0026] Through the above technical solution, the first upper hanging ear 11 and the second upper hanging ear 12 are vertically misaligned, and the first lower hanging ear 13 and the second lower hanging ear 14 are vertically misaligned, which facilitates the assembly of the crossbar 2 and avoids the ends of the crossbar 2 on adjacent sides from colliding.
[0027] It should be noted that when setting up the safety fence, the horizontal bar 2 should be assembled from bottom to top, and disassembled from top to bottom.
[0028] As one specific embodiment of the improvement, the lower end of the upright 1 is provided with a sharp insertion part.
[0029] With the above technical solution, the sharp insertion part makes it easy to insert the upright 1 into the pit for initial positioning, and assembly can be carried out by a single person without the need for assistance.
[0030] As an improved specific implementation, the crossbar 2 includes a first rod 41 and a second rod 42. The first rod 41 is provided with a connecting groove 411, and the second rod 42 is threadedly connected to the connecting groove 411.
[0031] With the above technical solution, the crossbar 2 located on the lower side of the gas pipeline can be disassembled into a first bar 41 and a second bar 42 during assembly, and then fixed into a single crossbar 2 by screwing on threads. This makes disassembly and assembly convenient, reduces the area of the excavated mud pit, and improves inspection efficiency.
[0032] As one specific implementation of the improvement, the card slot 21 is provided with several slots, which are spaced apart.
[0033] With the above technical solution, several card slots 21 are set at intervals, which are suitable for pits of different lengths and widths and have a wide range of applications.
[0034] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
