Description

Technical Field

[0001] The utility model relates to the field of steel structure buildings, in particular to a movable railing for edge protection. Background Art

[0002] At present, steel structure buildings have been widely used in various industries. Due to their rapidity, convenient installation and construction, strong structure, environmental protection and energy saving, they are likely to replace traditional buildings in some fields.

[0003] When a steel structure building is erected on site, there are many high-altitude edges on the construction site. There are no formal railings or walls during construction, and protective measures need to be taken. In the existing technology, temporary railings are generally set up with scaffolding, which is time-consuming and laborious. Utility Model Content

[0004] The utility model aims to provide a movable railing for edge protection to solve the problems existing in the prior art.

[0005] The purpose of the utility model is achieved as follows: a movable railing for edge protection, including columns arranged at intervals, a plurality of steel ropes horizontally connected between the columns, a cone head is provided at the bottom of the column, a nut matching the upper end of the expansion bolt is fixed at the bottom of the cone head, a long hexagonal sleeve is jacketed on the middle section of the expansion bolt, the long hexagonal sleeve is connected to the expansion bolt by a pin, a longitudinal slide groove matching the inner end of the pin is provided on the outer wall of the expansion bolt, and the lower end of the expansion bolt is connected to the ground.

[0006] When installing the movable railing for edge protection of the utility model, first use an impact drill to drill a hole on the ground that matches the expansion bolt, preliminarily connect the upper end of the expansion bolt with the nut fixed in the cone head at the bottom of the column, then install the lower end of the expansion bolt into the hole, and then directly twist the elongated hexagonal sleeve to drive the expansion bolt to rotate synchronously through the pin, so that the tail of the expansion bolt bulges out and the upper end is locked with the nut, thereby realizing a reliable connection between the column and the ground. Then install the wire rope to form a movable fence to ensure the safety of high-altitude construction. After the construction is completed, remove the wire rope, and then rotate the elongated hexagonal sleeve in the opposite direction to release the connection between the expansion bolt and the column and the ground, so that the movable railing can be disassembled, and the disassembled parts take up little space, are easy to store, and are convenient for transportation and storage. In summary, the movable railing for edge protection of the utility model has the advantages of quick disassembly and assembly, time and labor saving, easy transportation and storage, and high reuse rate.

[0007] As a further improvement of the utility model, the upright posts are made of steel pipes with a diameter of 60 mm and a thickness of 2.5 mm to ensure the strength of the railing.

[0008] As a further improvement of the utility model, the diameter of the steel wire rope is 9mm, which ensures the safety of use. A through hole with a diameter of 16mm is provided on the column corresponding to the connection position of the steel wire rope, which is convenient for the steel wire rope to be passed through.

[0009] As a further improvement of the utility model, the through hole is offset relative to the central axis, so that during installation, the steel wire rope can be closer to the inner side of the movable railing, thereby improving the safety of use.

[0010] As a further improvement of the utility model, the distance between the columns is less than 2m, and the distance between the steel wire ropes is less than 25cm, so as to ensure the safety of use.

[0011] As a further improvement of the utility model, the expansion bolts use M16 expansion bolts to ensure connection reliability. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] like Figure 1-3 The shown movable railing for edge protection includes columns 1 arranged at intervals. The columns 1 are made of steel pipes with a diameter of 60 mm and a thickness of 2.5 mm to ensure strength. Four steel wire ropes 2 are horizontally connected between the columns 1. The diameter of the steel wire rope 2 is 9 mm, which ensures safety in use. A through hole 9 with a diameter of 16 mm is provided on the column 1 corresponding to the connection position of the steel wire rope 2, which is convenient for the steel wire rope 2 to pass through. The through hole 9 is offset relative to the central axis, so that during installation, the steel wire rope 2 can be closer to the inner side of the movable railing, thereby improving safety in use. The distance between the columns 1 is less than 2m, and the distance between the steel wire ropes 2 is less than 25cm, which ensures safety in use.

[0017] like Figure 2 As shown, a cone head 3 is welded and fixed at the bottom of the column 1, a nut 5 that matches the upper end of the expansion bolt 4 is fixed at the bottom of the cone head 3, a long hexagonal sleeve 6 is covered on the middle section of the expansion bolt 4, the long hexagonal sleeve 6 is connected to the expansion bolt 4 through a pin 7, a longitudinal slot 8 that matches the inner end of the pin 7 is provided on the outer wall of the expansion bolt 4, and the lower end of the expansion bolt 4 is connected to the ground. The expansion bolt 4 uses an M16 expansion bolt to ensure connection reliability.

[0018] When installing the movable railing for edge protection of the present embodiment, first use an impact drill to drill a hole on the ground that matches the expansion bolt 4, preliminarily connect the upper end of the expansion bolt 4 with the nut 5 fixed in the cone head 3 at the bottom of the column 1, then install the lower end of the expansion bolt 4 into the hole, then directly twist the elongated hexagonal sleeve 6, drive the expansion bolt 4 to rotate synchronously through the pin 7, so that the tail of the expansion bolt 4 bulges and the upper end is locked with the nut 5, thereby realizing a reliable connection between the column 1 and the ground. Then install the steel wire rope 2 to form a movable fence to ensure the safety of the high-altitude construction. After the construction is completed, remove the steel wire rope 2, and then rotate the elongated hexagonal sleeve 6 in the opposite direction to release the connection between the expansion bolt 4 and the column 1 and the ground, and the disassembly of the movable railing can be completed, and the disassembled parts occupy little space, are easy to store, and are convenient for transportation and storage. In summary, the movable railing for edge protection of the present embodiment has the advantages of quick disassembly and assembly, time and labor saving, easy transportation and storage, and high reuse rate.
