Description

Scaffold joins externally safety net accessory

Technical Field

The invention relates to a scaffold, in particular to an external safety net accessory of a scaffold.

Background

The safety net is arranged at the periphery of the building construction scaffold, so that the falling injury of a person and an object can be effectively prevented, and the safety net is one of important facilities for building construction safety protection. Traditional safety net is flexible dense mesh, adopts the net of hanging to collude the cooperation and ties up the installation of rope, and the external safety net of scaffold of this kind of form has the trend that is replaced by rigid safety net gradually owing to have the turnover inefficiency, the bearing capacity is little, the installation with dismantle loaded down with trivial details and the facade scheduling problem that is pleasing to the eye inadequately. At present, a plurality of rigid safety nets are used, and each rigid safety net is composed of a metal net or a mesh plate arranged in a rectangular frame of a square pipe, has the characteristics of good safety performance, high turnover efficiency and smooth and attractive outer vertical surface of the safety net, and how to realize the efficient, high-quality and high-safety assembly of the rigid safety net and a steel pipe scaffold is a technical problem which needs to be solved urgently at present. In the prior art, the H-shaped slot pieces are arranged on the cross bars of the steel pipe scaffold, and the rectangular rigid safety net is inserted into the slots of the H-shaped slot pieces, so that the installation of the external safety net of the building steel pipe scaffold is realized. This kind of external safety net assembly structure of building steel pipe scaffold frame, each unit safety otter board transversely lacks fixedly, has reduced the security performance of each unit safety otter board of external safety net and the security performance of whole safety net protection system.

Disclosure of Invention

The invention aims to provide the external scaffold safety net accessory aiming at the defects in the prior art, the external scaffold safety net accessory can realize the high-efficiency, high-quality and high-safety assembly of the external rigid safety net of the building steel pipe scaffold, and has the characteristics of simple accessory structure and low product cost.

The technical scheme for realizing the purpose is as follows: the utility model provides a scaffold joins externally safety net accessory, is including installing the fastener on steel pipe scaffold frame horizontal pole, the fastener have through arc surface and scaffold frame horizontal pole complex detain seat and buckle closure, the lower extreme of detaining seat and buckle closure passes through lower end round pin axle hinge and connects, the upper end of detaining the seat is through upper end round pin axle hinge joint live bolt, the upper end of buckle closure be equipped with live bolt complex bolt caulking groove, the outside of detaining the seat is equipped with flat layer board, the higher authority of flat layer board is equipped with two transverse arrangement's the perpendicular cylinder of putting that is used for installing safe otter board below with respectively.

According to the scaffold external-hanging safety net accessory, the buckle seat is a groove-shaped part with a vertical plane on the outer side, the flat supporting plate is located in the middle of the vertical plane, and the longitudinal ribs on two sides of the groove-shaped part are provided with arc surfaces matched with the cross rods of the scaffold.

The invention has simple structure and low product cost, is convenient to assemble with the cross bar of the steel pipe scaffold and the rigid externally hung safety net, can realize the transverse and vertical fixation of the externally hung safety net plate, and can greatly improve the installation efficiency, the installation quality and the safety performance of the rigid externally hung safety net.

Fig. 2 is a schematic view of an assembly structure of the scaffold external-hanging safety net accessory, a scaffold cross bar and a safety net plate.

In the figure: 1. a buckle seat; 2. covering; 3. a lower end pin shaft; 4. an upper end pin shaft; 5. an eye bolt; 6. a flat supporting plate; 7. vertically arranging a cylinder; 8. a scaffold rail; 9. a safety mesh plate.

Detailed Description

The invention is further explained by combining the drawings and the embodiments.

As shown in fig. 1 and 2, the scaffold external safety net accessory comprises a fastener installed on a steel pipe scaffold cross rod 8, wherein the fastener is provided with a buckle seat 1 and a buckle cover 2 which are matched with the scaffold cross rod 8 through an arc surface, the lower ends of the buckle seat 1 and the buckle cover 2 are hinged through a lower end pin shaft 3, the upper end of the buckle seat 1 is hinged with a movable joint bolt 5 through an upper end pin shaft 4, the upper end of the buckle cover 2 is provided with a bolt caulking groove matched with the movable joint bolt 5, the outer side of the buckle seat 1 is provided with a flat supporting plate 6, and the upper surface and the lower surface of the flat supporting plate 6 are respectively provided with two vertically-arranged cylinders 7 which are transversely arranged and used for installing a safety net plate 9.

According to the scaffold external safety net accessory in the embodiment of the attached drawing, the buckle seat 1 is a groove-shaped part with a vertical plane on the outer side, the flat supporting plate 6 is located in the middle of the vertical plane, and the longitudinal ribs on two sides of the groove-shaped part are provided with arc surfaces matched with the cross rods 8 of the scaffold.

This detain seat 1 and buckle closure 2 of scaffold frame external safety net accessory is fit for adopting the steel casting, simultaneously, detains seat 1 and flat backup plate 6 can integrated into one piece, detains seat 1, flat backup plate 6 and erects and put also can integrated into one piece of cylinder 7. The lower ends of the buckle seat 1 and the buckle cover 2 can be respectively set into double-side lug plate structures which are matched with each other, and hinged connection is realized through a lower end pin shaft 3. In the embodiment of fig. 1, the lower end of the buckle cover 2 is arranged to be a cylindrical structure with a pin shaft through hole in the center to be matched with the double-side ear plates at the lower end of the buckle base 1, and is hinged through a lower end pin shaft 3. The upper end pin shaft 4 is assembled and hinged with the swing bolt 5 through a double-lug plate structure arranged at the upper end of the buckle seat 1. The top end of the vertical column 7 is chamfered to facilitate the installation of the safe screen plate 9.

Referring to fig. 2, when the scaffold safety net plate mounting device is used, the arc surfaces of the buckle seat 1 and the buckle cover 2 are matched with the cylindrical surface of the scaffold cross bar 8, the swing bolt 5 is rotated to enable the screw rod to be embedded into the bolt embedding groove at the upper end of the buckle cover 2, the nut of the swing bolt 5 is screwed to fix the fastener on the scaffold cross bar 8, and the safety net plate 9 is mounted and fixed by utilizing the insertion and matching of the inner hole of the square tube at the side frame of the safety net plate 9 and the vertically-arranged column 7.

The buckle cover 2 adopts the circular arc surface to be matched with the cylindrical surface of the scaffold cross rod 8, and the buckle seat 1 adopts the circular arc surfaces arranged on the longitudinal ribs at two sides to be matched with the cylindrical surface of the scaffold cross rod 8, so that the strength and the rigidity of the buckle are ensured, and the performance of fixing and matching the buckle cover with the scaffold cross rod 8 is improved. According to the invention, the buckle base 1 is arranged to be a channel-shaped part with an outer vertical plane, so that the strength and rigidity of the buckle base 1 are ensured, the weight of the buckle base 1 is favorably reduced, and the axial distance between the vertical column 7 and the scaffold cross bar 8 is shortened as much as possible, so that the stress condition of the scaffold external safety net accessory is improved.
