[0019] By referring to the exemplary embodiments, the purposes and functions of the present invention and the methods for achieving these purposes and functions will be explained. However, the present invention is not limited to the exemplary embodiments disclosed below; it can be implemented in different forms. The essence of the description is only to help technicians in the relevant field to comprehensively understand the specific details of the present invention.

[0020] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0021] Figure 1 The utility model schematically shows a multifunctional building guardrail, which includes columns 1, a fixed base 2 located between the columns 1, a fixed cross frame 3 located at the upper end of the columns 1, a lighting warning lamp 4 located above the upper end of the columns 1, and a plurality of telescopic rods 5 whose two ends are respectively vertically connected to the fixed base 2 and the fixed cross frame 3, wherein the fixed cross frame 3 is a concave structure with its opening upward.

[0022] A plurality of first through holes 31 are evenly spaced at the bottom center of the fixed cross frame 3. A circular top cover 54 having a diameter larger than that of the first through hole 31 is provided at the upper end of the first rod 51. After passing through the first through hole 31, the first rod 51 is downwardly connected to the second rod 52 through a locking mechanism 53.

[0023] like Figure 2 As shown in (a), the telescopic rod 5 is a two-stage telescopic rod, which includes a first-stage rod 51 located at the top, a second-stage rod 52 located at the bottom, and a locking mechanism 53 connecting the first-stage rod 51 and the second-stage rod 52. The telescopic rod 5 can be adjusted in length according to specific usage needs, and then locked by the locking mechanism 53, thereby expanding the application scenarios of the telescopic rod 5.

[0024] like Figure 2 As shown in (b), an elastic latch mechanism 55 is provided at the lower end of the second rod 52, and the elastic latch mechanism 55 comprises a housing 551 with openings at both ends, a spring 552 located inside the housing 551, and a cylindrical latch 553 connected to the spring 552 at one end and connected to the other end, and the latch 553 passes through the openings at both ends of the housing 551. Further, a plurality of symmetrical second through holes 21 are provided on both sides of the fixed base 2, and the latch 553 is inserted into the second through holes 21 to fix the lower end of the second rod 52. The elastic latch mechanism 55 has the advantages of simple structure, quick installation, stability and reliability, etc.

[0025] like Figure 3 As shown, the fixed base 2 and the fixed cross frame 3 are preferably made of channel steel to facilitate material acquisition and reduce costs. Further, a sensing optical fiber 6 and a water pipe 7 pressed on the sensing optical fiber 6 are laid at the center of the inner bottom of the fixed cross frame 3. Specifically, the sensing optical fiber 6 is laid on the circular top cover 54 and can be fixed on the circular top cover 54 by adhesive. The sensing optical fiber 6 between adjacent circular top covers 54 is in a suspended state, and the bottom of the water pipe 7 is pressed on the circular top cover 54 and the sensing optical fiber 6. The sensing optical fiber 6 is in close contact with the circular top cover 54 and the bottom of the water pipe 7 at the same time, thereby improving the sensitivity of the sensing optical fiber 6 and making it easier to sense subtle pressure changes and the location of pressure changes.

[0026] In addition, a plurality of atomizing nozzles 71 are evenly and evenly laid on the upper side of the water pipe 7. The atomizing nozzles 71 spray water mist into the air, which can effectively reduce dust in dusty environments such as construction sites and reduce the temperature to prevent construction workers from heatstroke.

[0027] Further, the two ends of the sensing optical fiber 6 are respectively connected to the light source transmitter and the modulator. The working principle of the optical fiber sensing pressure measurement is based on the change of light intensity caused by the micro-bending deformation of the optical fiber, thereby causing the change of the optical fiber transmission loss. This process can be achieved by the micro-bending deformation of the optical fiber. When pressure is applied in a direction perpendicular to the optical axis of the optical fiber, the optical fiber will change, resulting in a change in the optical waveguide mode, thereby increasing the transmission loss. The optical fiber has a high sensitivity and can measure the pressure by the change of light intensity. Therefore, when the pressure / stress of the fixed horizontal frame 3, the telescopic rod 5 and the water pipe 7 changes slightly, it can be sensed by the sensing optical fiber 6, and the position of the pressure / stress change can be further obtained, so as to timely alarm and maintain through the lighting warning light 4. When someone destroys the guardrail, climbs over the guardrail or the water pipe 7 breaks, the sensing optical fiber 6 can sense and issue an alarm reminder, effectively ensuring the personal and property safety of the construction site.

[0028] In summary, the utility model is a multifunctional building guardrail which adopts a combined design and optical fiber sensing technology, and has many advantages such as simple structure, quick assembly, comprehensive functions, sensitive sensing, safety and reliability.
