[0058] On-site installation

[0059] 1. The thickness of the concrete foundation shall not be less than 150mm, and the effective width of the installation surface shall not be less than 150mm. The foundation surface shall be flat.

[0060] 2. Tools: electric hammer, hammer, wrench, hexagonal wrench, pliers, galvanized iron wire, etc.

[0061] Stand, beam

[0062] Requirements:

[0063] 1. The height of the column shall not be less than 1.2m, made of 50*50*2.5mm square tube, with column head at the top, and red paint sprayed on the middle and upper parts. The bottom is welded with 120*120*6mm punched steel plate, with hole diameter not less than 10mm.

[0064] 2. The column connecting piece is made of L5*3 angle steel, with the inner corner facing the back of the guardrail, the inner opening upward, and the bottom surface punched in the middle with a diameter not less than 8mm. The upper and lower two 30*30*1.5mm square tube beams are provided with the same connecting holes.

[0065] 3. M6 standard nut is welded at the position directly below the punched hole of the angle steel, for easy on-site installation.

[0066] 4. For sites that serve as regional demarcation, road guiding separation and have no hardened foundation, temporary installation can be carried out using the placed guardrail.

[0067] Steel wire rope connector 4, as shown in Figure 2 :

[0068] Requirements:

[0069] 1. The steel wire rope connector 4 is made of 304 stainless steel material, and the standard parts of the matching steel wire rope are selected.

[0070] 2. The flexible steel wire rope should be adjusted according to the height of the guardrail. The screw rod in the steel wire rope connector is only used to tighten the steel wire rope and adjust the length of the steel wire rope in the component.

[0071] 3. Specifications: screw rod φ8mm, length 55mm; sleeve outer diameter 14mm, inner thread matched with screw rod, length 50mm, punched hole at the corresponding position of the cylinder body, hole diameter 12mm, 2 on one side, 1 on the other side; top wire φ12mm, length 6mm, end head is hexagonal, installed and removed with hexagonal wrench.

[0072] Installation requirements for crossbeam 2 and flexible steel wire rope 3

[0073] 1. The connection between the crossbeam and the wire rope can be completed in the factory. The wire rope, connector sleeve, nut, etc. between the upper and lower crossbeams should be on the same horizontal line.

[0074] 2. At each wire rope connection end, the set screw should be tightly pressed against the wire rope, and the set screw should be screwed into the sleeve, slightly below the outer surface of the sleeve.

[0075] 3. At each connection end, the cap nut and ordinary nut should be tightened to the square tube. The extension and tightening of the wire rope can be adjusted by the length of the screw extending into the sleeve (fine adjustment).

[0076] 4. Other types of guardrails, such as elevator shaft guardrails requiring a height of not less than 1.5m, can be manufactured using the design format described in this manual. Due to the diverse architectural structures and dimensions of elevator shaft openings, design and production should be tailored to specific circumstances. For easy wall fixing, connectors can be installed at both ends of the crossbeams; for openings without walls or with secondary structures built later, two posts can be installed at each opening.

[0077] 5. For example Figure 3 and Figure 4 As shown: Depending on actual needs, the connection can be either a two-end live connection or a two-end sleeve welded and manually tightened connection.

[0078] (1) The two-end live connection type requires manual connection, tightening, and adjustment using a wire rope connector. This method is relatively labor-intensive, but has lower requirements for the accuracy of the wire rope length. As shown in the figure:

[0079] (2) A connection method involving welding and manually tightening the sleeves at both ends. The wire rope connector 4 retains only the sleeve portion, which is then welded to the upper and lower crossbeams according to its corresponding position. This method increases welding work but reduces manual connection and adjustment labor; only manual connection and tightening of the wire rope are required. Simultaneously, precise control of the wire rope length is necessary to ensure processing and forming quality. (See figure).

[0080] The new type of tool-type flexible edge protection fence is installed as a whole, such as Figure 5 As shown:

[0081] 1. After the wire rope is connected to the crossbeam, it can be installed and used in conjunction with the standard column 1, kick plate 7, warning sign 6, etc. The installation of other components is extremely simple and will not be described in detail here.

[0082] 2. If the site conditions require the installation of guardrails of irregular sizes during the construction process, adjustments can be made and new guardrails can be fabricated accordingly.

[0083] 3. During use, the wire rope should always be kept taut. If it becomes loose or comes loose, it should be tightened again or replaced.

[0084] 4. In the obvious position of guardrail should be safety tips, strictly prohibit the site personnel from flexible "stand pole" between access or damage the installation acceptance after the working condition of guardrail.

[0085] 5. Guardrail as a demarcated area, guide separation and other ways to use, such as shown in Figure 6 : also can be connected, fastening, adjusting the flexible steel wire rope horizontally, the distance between the vertical column, the length of the steel wire rope can be adjusted according to the site conditions.

[0086] 6. When storing, the various independent installation of guardrail components are classified and stored, the upper and lower horizontal poles of the vertically arranged guardrail can be stored together with the steel wire rope, the vertical column of the horizontally arranged guardrail and the steel wire rope are stored together, reducing the installation and disassembly work and saving the site.

[0087] The technical principles of the present application are described above in combination with specific embodiments, and these descriptions are only for explaining the principles of the present application, and cannot be interpreted as limiting the protection scope of the present application in any way. Based on the above explanation, the skilled in the art can think of other specific embodiments of the present application without any creative labor, and these embodiments will all fall within the protection scope of the present application.​
