Problems solved by technology

As a crossbar for border protection, its load-bearing capacity requirements are not high. According to JGJ80-91 "Safety Technical Specifications for Building Construction at Heights", the length of the crossbar in border protection is 2 meters, and the load-bearing requirement is 1000N. , and the strength of the φ48X3.5 steel pipe used now far exceeds the requirements for use
The current building border guardrails have problems such as inconvenient transportation, cumbersome installation and disassembly, etc.

Embodiment 1

[0016] Such as figure 1 As shown, the present invention provides a kind of building edge protective railing, comprises the column 1 that is made by the commonly used steel pipe of φ48X3. The expansion bolts on the fixing seat fix the column 1 on the floor. The upright column 1 is connected with the top cross bar and the middle section cross bar 3 by hinges 4 . The column 1, the top cross bar 2 and the middle cross bar 3 form a parallelogram structure through the hinge 4, which can be folded and placed during transportation and storage, saving a lot of space.

Embodiment 2

[0018] Such as figure 2 As shown, the structure of embodiment 2 is basically the same as that of embodiment 1, wherein the hinge 4 is still used to connect the column 1 and the top cross bar 2. The difference is that in this embodiment, a steel pipe is welded in the middle section of the column 1 as a connecting cylinder 41. The connecting cylinder 41 has a diameter of 41 mm, and the middle crossbar 3 is inserted into the connecting cylinder 41 to form a guardrail. During transportation and storage, the column 1 and the top cross bar 2 are folded and stored, while the middle cross bar 3 is stored separately.

Embodiment 3

[0020] Such as image 3 , Figure 4 As shown, the structure of embodiment 3 is basically the same as that of embodiment 1, wherein the hinge 4 is still used to connect the column 1 and the top cross bar 2, and the difference is that a steel pipe is welded in the middle section of the column 1 as a connecting cylinder in this embodiment 42. The connecting cylinder 42 has a diameter of 41 mm, and the connecting cylinder 42 is provided with a reed 43. The end of the middle cross bar 3 is in an L row, and is naturally clamped by the reed 43 after being inserted into the connecting cylinder 42.

Abstract

The invention discloses a foldable protective barrier near one side of a building. The foldable protective barrier comprises a plurality of upright pillars, wherein the bottom of each upright pillar is fixedly connected with a building surface; the upright pillars are sequentially connected in a hinged way by transverse bars at the top; and the axes of rotating shafts connected in a hinged way are parallel to one another. The size and the specification of parts take the prior art as reference, large-scale change is not needed. In the whole connection system of the protective barrier, the connection type of traditional steel pipe fastener is abandoned, fastener connection is completely given up, the cost is saved greatly and the whole weight of the protective barrier is reduced. A hinge connection structure is adopted between the upright pillars and the transverse bars at the top, so that the protective barrier is can be folded during transport and storage processes, the transport space is saved, fastener connection is not needed, and the transported weight and the storage space are reduced. During the installation of the foldable protective barrier, only hinges are rotated to a proper angle and the upright pillars are fixed on the building surface; both installation and detachment are convenient and time and labor force are saved greatly.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a border protection railing applied to the construction stage of a main body of a building. Background technique [0002] In the process of building construction, in accordance with safety regulations and civilized construction requirements, a large number of four-mouth and five-side protections must be made, such as openings, stairs, and exterior walls. The general structure includes vertical rods and horizontal rods. Usually φ48X3.5mm steel pipe is used, and the vertical bar and the horizontal bar are connected by fasteners. The steel consumption is relatively large. The steel pipe is 3.85kg / m, and the fastener is 1.25kg / piece. As the crossbar for border protection, its load-bearing capacity requirements are not high. According to JGJ80-91 "Safety Technical Specifications for Building Construction at Heights", the length of the crossbar for border prot...
