Description

Construction site safety guardrail group

The present invention relates to a safety protection device for elevated operations, in particular to a safety guardrail used for elevated operations.

In order to allow personnel to perform high-altitude operations more safely, equipment such as work frames and working platforms will be erected at the construction site to facilitate personnel movement, and various safety protection measures will be erected, such as guardrails, safety nets, safety cables, etc. To protect personnel from falling, in addition, personnel also need to wear safety protective equipment, such as helmets, safety belts, and anti-fall devices, to provide relevant safety protection to prevent accidental injuries in the event of an accidental fall.

Please refer to Figure 6. The existing construction site safety guardrail group 90 is mainly erected on the working platform to prevent people and objects from accidentally falling. The working platform mainly includes a plurality of spaced beams and walkway boards laid above the beams. The construction site The safety guardrail group 90 mainly includes a foot base 91, a column 92, and a plurality of cross bars 93. The foot base 91 is fixed on the walkway board, the column 92 is socketed and fixed on the foot base 91, and each cross bar 93 is connected to adjacent ones. The columns 92 of the construction site safety guardrail group 90 are usually provided with safety cables on the existing construction site safety guardrail group 90. Workers will wear safety belts during construction and hook them on the safety cables to prevent accidents. Fall.

The foot base 91 mainly includes a bottom plate 911 and a sleeve 913, and a plurality of bolts are used to lock the bottom plate 911 to the walkway plate. However, since the foot base 91 is only fixed to the walkway plate using bolts, the stability is insufficient. When the existing construction site safety guardrail 90 is pulled by a large external force, the base 91 may shake and become loose, thereby affecting the safety of the existing construction site safety guardrail 90 .

In view of the above shortcomings, the main purpose of the present invention is to provide a construction site safety guardrail set, the base of which can be firmly erected on the beam of the working platform, thereby improving the safety and stability of the construction site safety guardrail set.

In order to achieve the above purpose, this new type of construction site safety guardrail group includes: A foot base, the foot base includes a support part and a pipe, the support part includes a support plate, two side plates, two installation plates, and two installation slots, the two side plates are respectively from the opposite sides of the support plate. Extending downward, the two mounting plates extend toward each other from the two side panels, and a slot is formed between the two mounting plates. The two mounting slots are respectively formed between the two mounting plates and the supporting plate, and are connected with the supporting plate. The slots are connected, and the pipe extends upward from the supporting plate; A plurality of resisting members, the plurality of resisting members are screwed to the two mounting plates and penetrate into the two mounting grooves from below the two mounting plates; an upright column coupled to the nozzle of the foot base; and A plurality of cross bars are fixed on the upright column.

Utilizing the above technical features, the support part of the foot base can be connected to a cross beam of a working platform, the support plate is close to the outer surface of a wing plate of the cross beam, and the opposite sides of the wing plate extend into the support respectively. In the two installation grooves of the base, the plurality of resisting members are used to press against the inner surface of the wing plate, so that the supporting plate is tightly abutted against the outer surface of the wing plate, so that the support part of the foot base is stable The wings are groundly covered and fixed to the beam to enhance the stability and safety of the new construction site safety guardrail set.

Please refer to Figures 1 to 5, a preferred embodiment of the new construction site safety guardrail set is used to erect on a working platform 50. The working platform 50 includes a plurality of cross beams 51 arranged at intervals and is laid on the plurality of cross beams 51. There is a walkway plate 53 above the cross beam 51 to facilitate people to move on the walkway plate 53. Each cross beam 51 can be an H-shaped steel, which includes a base plate 513 and two wing plates 511 located on opposite sides of the base plate 513.

The construction site safety guardrail set includes a foot base 10 , a plurality of resisting members 15 , a column 20 , and a plurality of crossbars 30 .

Please refer to FIGS. 1 to 4 . The foot base 10 is used to be fixed on the crossbeam 51 . The foot base 10 includes a support part 11 and a pipe 13 . The support part 11 is used to erect a wing plate 511 fixed on the cross beam 51. The support part 11 includes a support plate 111, two side plates 113, two installation plates 115, and two installation slots 112. The support plate 111 is used for Close to the outer surface of the wing plate 511, the two side plates 113 extend downward from the opposite sides of the support plate 111 and are respectively located on the opposite sides of the wing plate 511. The two mounting plates 115 are respectively extended from the two opposite sides of the support plate 111. The bottom ends of the side plates 113 extend toward each other and are located inside the wing plate 511. A slot 114 is formed between the two mounting plates 115, so that the base plate 513 of the cross beam 51 passes through the slot 114. The two mounting slots 112 are respectively formed between the two mounting plates 115 and the supporting plate 111 and are connected with the slot 114 so that the opposite sides of the wing plate 511 extend into the two mounting grooves 112 of the support part 11 respectively.

The plurality of resisting members 15 are screwed to the two mounting plates 115, and penetrate into the two mounting grooves 112 from the bottom of the two mounting plates 115 to resist the inner side of the wing plate 511, so that the supporting plate 111 tightly abuts the outer surface of the wing plate 511 of the cross beam 51 , and the support portion 11 of the foot base 10 can be firmly fixed to the wing plate 511 .

The pipe 13 extends upward from the support plate 111, and the column 20 is connected to the pipe 13 of the foot base 10. The column 20 may include a support column 25 and an outer tube 21. One end of the support column 25 extends in and is fixed on The other end of the pipe 13 extends out of the pipe 13 , and the outer pipe 21 is sleeved and fixed on the outer periphery of the support column 25 .

Please refer to Figures 1 to 3. The plurality of cross bars 30 are fixed on the upright column 20. The plurality of cross bars 30 are connected and fixed on the upright column 20 with a connecting device 40. The connecting device 40 includes at least one fixed plate 41, a plurality of The at least one fixing plate 41 is fixed on the upright column 20 and is provided with a plurality of buckle grooves 412. The plurality of joint parts 43 are respectively fixed on the plurality of cross bars 30. At one end, each connector 43 may include a clamping block 431 and a slot 434. The clamping block 431 is clamped on the at least one fixed plate 41 and has a laterally extending clamping groove 432 into which the at least one fixed plate 41 extends. The clamping groove 432 and the slot 434 pass through the clamping block 431 up and down and are connected with the clamping slot 432. Each plug-in member 45 is inserted into the slot 434 of a corresponding connector 43 and is fixed by the at least one The buckle groove 412 of the disk 41 is used to fasten its corresponding connector 43 to the at least one fixed disk 41 . The connecting device 40 can also use other existing connecting devices, as long as the plurality of cross bars 30 can be connected and fixed to the upright column 20 .
