Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

A construction platform for a steel beam facade is shown in figures 1 and 2 and comprises a vertical ladder 1 and a stress assembly 2 arranged at the upper end of the vertical ladder 1.

As shown in fig. 2, the vertical ladder 1 includes two vertical bars 11 vertically arranged, and a plurality of horizontal bars 12 horizontally arranged between the two vertical bars 11 (in this embodiment, the number of the horizontal bars 12 is four, and the horizontal bars are uniformly arranged along the height direction of the vertical bars 11). The stress assembly 2 comprises two extension rods 21 arranged in parallel and two stress rods 22 fixedly connected between the two extension rods 21, two ends of each stress rod 22 are vertically fixedly connected to the side wall of the corresponding extension rod 21, and the interval between the two stress rods 22 is equal to the interval between every two rows of stress nails 32. The ends of the two extension rods 21 are hinged on the side walls corresponding to the ends of the vertical rods 11, and the hinged shafts of the extension rods 21 and the vertical rods 11 are parallel to the central line of the cross rod 12. The limiting plate 23 of an L type is fixedly connected to the upper end of each vertical rod 11, the two sides of the limiting plate 23 are respectively welded to the side wall and the end face of each vertical rod 11, after the extension rod 21 is hinged to the vertical rod 11 to open and close, the upper surface of the vertical rod 11 abuts against the lower surface of the limiting plate 23, and therefore the maximum opening and closing angle of the stress assembly 2 is limited.

When fixing the construction platform, rotatable extension rod 21 makes atress subassembly 2 be 90 degrees with vertical ladder 1 under the restriction of limiting plate 23, then places two atress poles 22 on the upper surface of channel steel roof beam 31 from the gap between two rows of shear force nails, under vertical ladder 1 action of gravity, makes atress pole 22 tightly lean on one side at the shear force nail to the stability that vertical ladder 1 hung has been ensured. Because atress subassembly 2 and vertical ladder 1 are articulated each other for when transporting construction platform, can articulate atress subassembly 2 and lean on the lateral wall of vertical ladder 1, thereby be convenient for the transportation of vertical ladder 1 to accomodate.

As shown in fig. 2, one side that vertical ladder 1 deviates from atress subassembly 2 is provided with one and encloses guardrail 4, it is parallel to each other with vertical ladder 1 place plane to enclose guardrail 4, the both sides that enclose guardrail 4 respectively are provided with two connecting rods 41, the one end of connecting rod 41 is rotated with the lateral wall that encloses guardrail 4 and is connected, the other end and the vertical ladder 1 lateral wall of connecting rod 41 rotate to be connected, the axis of rotation at connecting rod 41 both ends all is parallel to each other with the axis of rotation of montant 11 and extension rod 21, two connecting rods 41 intervals set up, and four connecting rods 41 are parallel to each other, thereby played to enclosing the both sides of vertical ladder 1 and established the effect.

As shown in fig. 2, two sets of supporting components 5 supported by the surrounding guardrails 4 are respectively arranged on two sides of the vertical ladder 1. Prop up and establish subassembly 5 including first branch 51 and with first branch 51 one end articulated second branch 52, the other end of first branch 51 rotates with vertical ladder 1 lateral wall to be connected, second branch 52 deviates from the other end of first branch 51 and rotates with enclosing guardrail 4 lateral wall to be connected, first branch 51 all is parallel to each other with horizontal pole 12 with vertical ladder 1's articulated shaft and second branch 52 and enclosing guardrail 4's articulated shaft, and the fixed point of first branch 51 and vertical ladder 1 is higher than the fixed point of second branch 52 and vertical ladder 1, and the subassembly 5 position of propping up of both sides corresponds each other.

When the connecting rod 41 rotates to be perpendicular to the plane of the straight ladder 1, the first supporting rod 51 and the second supporting rod 52 are in the same straight line, so that the mutual rotation of the connecting rod 41 and the straight ladder 1 is limited, and the stability of the supporting of the guardrail 4 is guaranteed; and when a person steps on the vertical ladder 1, the arrangement of the fence also improves the working safety of the person.

As shown in fig. 1 and 2, two stabilizing struts 6 are respectively arranged on two sides of the enclosure fence 4, four stabilizing struts 6 are parallel to each other with the connecting rod 41, one end of each stabilizing strut 6 is rotatably connected with the side wall of the enclosure fence 4, the other end of each stabilizing strut 6 is abutted against the outer vertical surface of the channel steel beam 31, the region where the stabilizing strut 6 is attached to the straight ladder 1 is rotatably connected with the side wall of the straight ladder 1, and the rotating shafts of the stabilizing struts 6 and the enclosure fence 4 and the rotating shafts of the stabilizing struts 6 and the straight ladder 1 are parallel to the length direction of the cross rod 12. And the positions of the stabilizing support rods 6 on the left side and the right side correspond to each other, one pair of the stabilizing support rods 6 are positioned at the tail ends of the surrounding guardrail 4 and the vertical ladder 1, a plurality of support rods 62 which are parallel to each other are arranged between the stabilizing support rods 6 at the two bottoms, and the two ends of each support rod 62 are respectively and vertically fixedly connected with the side wall of the stabilizing support rod 6. When four stabilizing support rods 6 are erected on the outer vertical surface of the channel steel beam 31, the vertical ladder 1 is stably supported, the erecting stability of the vertical ladder 1 is improved, the support rod 62 is horizontally arranged at the bottom of the vertical ladder 1, so that a person can conveniently trample and walk on the support rod 62, the activity space of the person is increased, the hand is vacated to support the vertical ladder 1, and the flexibility of spraying work is improved.

As shown in fig. 2, a rubber block 61 is further fixed on the end face of each stabilizing support rod 6, which is attached to the channel steel beam 31, and the rubber block 61 contacts the outer vertical face of the channel steel beam 31, so that the edges and corners of the end portions of the stabilizing support rods 6 are not easy to slip off from the paint surface of the channel steel beam 31, and the supporting of the escalator 1 is buffered, thereby improving the stability of the construction platform during construction.

As shown in fig. 3, when the staff transports construction platform, can be with the atress subassembly 2 through extension rod 21 with montant 11 articulated, make atress subassembly 2 receive and release in one side of vertical ladder 1, rotation through connecting rod 41, the drive dimension guardrail is to the direction removal of vertical ladder 1, and make first branch 51 and second branch 52 rotate the stack, thereby construction platform's space occupation has been saved greatly, the convenience of transportation has been improved, and construction platform simple structure, be convenient for large-scale production, when spraying paint or weldment work, can erect a plurality of construction platform simultaneously, not only control conveniently, and improve the efficiency of spraying paint or weldment work greatly.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
