Problems solved by technology

[0004] However, the guardrail needs to be dismantled after the construction is completed. Ordinary guardrails are mostly disassembled by modularization and reconnected when they are used next time. However, after the guardrails are modularized, each guardrail unit has a large number of holes, which makes a guardrail unit occupy a relatively large area. Large, inconvenient for transportation and storage. If all the guardrails are disassembled and the railing is the smallest unit, the process of disassembly and reassembly will be too complicated, which will seriously reduce the construction efficiency, and there is still room for improvement

Embodiment 2

[0070] The difference from Example 1 is that, referring to figure 2 , the horizontal heights of all connecting plates 84 are consistent, connecting rings 841 are fixed on the connecting plates 84, and the flexible net 8 also includes a horizontal stay rope 85 that runs through all connecting rings 841 and connects end to end. When the two auxiliary sliders 7 located at both ends of the length direction of the main railing 2 and with the largest spacing are located at both ends of the length direction of the auxiliary railing 3 , the horizontal stay rope 85 is in a tight state.

[0071]The mesh opening of the flexible net 8 is further reduced by the horizontal pull rope 85 to better prevent people from falling, and at the same time, the local force of the flexible net 8 is distributed to the entire flexible net 8 by the taut horizontal pull rope 85 to avoid local stress The flexible net 8 is damaged, and the stability of the flexible net 8 is improved.

Embodiment 3

[0073] The difference with embodiment 2 is that, referring to figure 2 The support column 11 is detachably connected with a connecting railing 13, and the support column 11 is fixed with a fixed block 12 between the main railing 2 and the auxiliary railing 3. The fixed block 12 is located on the side of the support column 11 facing the construction site. The fixed block 12 There is a fixed groove downwardly recessed along the vertical direction, and the two ends of the fixed groove are connected with the outside along the length direction of the main railing 2. The connecting railing 13 is clamped in the fixing groove, and passes through the fixing block 12 and the connecting railing 13 through threaded fasteners. And abut on the support column 11 so that the support column 11 is connected with the connecting railing 13, the connecting railing 13 is located on the side of the flexible net 8 away from the construction site, the height of the connecting railing 13 is located bet...

Embodiment 4

[0076] The difference with embodiment 3 is that, referring to figure 2 , the main locking rod 221 is a rectangular rod, and the main locking rod 221 is provided with a main friction layer 222 on one side facing the main slider 6. In this embodiment, the main friction layer 222 is made of rubber. In other embodiments, polyurethane, Plastic etc.

[0077] The auxiliary locking rod 321 is a rectangular rod, and the side of the auxiliary locking rod 321 facing the auxiliary sliding part 7 is provided with an auxiliary friction layer 322. In this embodiment, the auxiliary friction layer 322 is made of rubber. In other embodiments, polyurethane, plastic, etc. can be used. Wait.

[0078] The main friction layer 222 increases the coefficient of friction of the side of the main locking rod 221 facing the main sliding part 6, so that the frictional force increases when the main locking rod 221 is pressed against the top of the main sliding part 6, and the locking of the main sliding pa...

Abstract

The invention relates to a guardrail facility, and provides a prefabricated guardrail. The prefabricated guardrail solves the problems of inconvenient loading, inconvenient unloading, inconvenient storage and inconvenient transportation. According to the technical scheme, the prefabricated guardrail comprises a plurality of guardrail units, the guardrail units comprise supporting columns, the supporting columns are detachably connected with primary handrails and secondary handrails, the primary handrails are connected with a plurality of primary sliding pieces in a sliding mode, and the primary handrails are provided with primary locking pieces for limiting the sliding the primary sliding pieces. The secondary handrails are connected with secondary sliding pieces with the same number as the primary sliding pieces, the secondary handrails are provided with secondary locking pieces for limiting the sliding of the secondary sliding pieces. The guardrail units further comprise flexible nets connected with the primary sliding pieces and the secondary sliding pieces. When disassembling, the flexible nets can be folded and placed, the primary handrails and the secondary handrails and thesupporting columns can be disassembled, the guardrail units can be completely disassembled and placed tightly, disassembly is convenient, and transportation and storage are convenient; and the flexible nets can be opened by sliding the primary sliding pieces and the secondary sliding pieces, and installation operation is convenient.

Description

technical field [0001] The invention relates to a guardrail facility, more specifically, it relates to an assembled guardrail. Background technique [0002] In the process of building construction, in order to protect the safety of personnel working at heights, it is necessary to set up guardrails around the work at heights to prevent personnel from falling. [0003] The general guardrail is fixedly connected by welding, so that the guardrail has better strength to ensure the effect of protecting the safety of personnel. [0004] However, the guardrail needs to be dismantled after the construction is completed. Ordinary guardrails are mostly disassembled by modularization and reconnected when they are used next time. However, after the guardrails are modularized, each guardrail unit has a large number of holes, which makes a guardrail unit occupy a relatively large area. Large, inconvenient for transportation and storage. If all the guardrails are disassembled and the raili...
