Description

Technical Field

[0001] The utility model relates to the technical field of high-rise building facade construction, in particular to a hanging basket adjustable height-increasing steel bracket. Background Art

[0002] As a classic aerial construction machinery, the function of the hanging basket is to carry workers up and down along the facade of the building to carry out curtain wall installation, exterior wall cleaning, insulation layer construction, exterior wall maintenance and other work processes. The hanging basket is installed on the steel bracket on the roof via a traction rope. Specifically, the steel bracket includes two left and right brackets, each bracket includes two front and rear square steel columns and a cantilever beam, and the tops of the front and rear square steel columns are welded to the cantilever beam; the cantilever beam of the left bracket is installed with a left traction rope via a left pulley block, and the cantilever beam of the right bracket is installed with a right traction rope via a right pulley block, and the left and right traction ropes are respectively fixed to the left and right ends of the hanging basket.

[0003] When the parapet on the top of the building is high, or there is an overhead structural layer area, etc., ordinary height steel brackets cannot be used to set up the hanging basket, and only heightened steel brackets that are higher than the standard height specified in the manufacturer's instructions can be selected. The standard height specified in the manufacturer's instructions generally does not exceed 170cm. This application involves heightened steel brackets. According to construction safety regulations, when the bracket height exceeds 170cm, in order to avoid instability, the same square steel columns of the left and right brackets must be connected and reinforced with scissor braces. That is, two intersecting diagonal braces are set between the front steel column of the left bracket and the front steel column of the right bracket, and two intersecting diagonal braces are also set between the rear steel column of the left bracket and the rear steel column of the right bracket.

[0004] In the prior art, the connection structure between each diagonal brace and the corresponding square steel column is that each square steel column is penetrated with a mounting hole in the front-to-back direction, each end of each diagonal brace is penetrated with a through hole, and each end of each diagonal brace is fixed to the corresponding square steel column via a shear bolt, and the shear bolt passes through the through hole at the end of the diagonal brace and the mounting hole of the corresponding square steel column at the same time. The mounting holes of each square steel column are divided into upper mounting holes and lower mounting holes, which are respectively used for screw connection with the upper end or the lower end of the diagonal brace; and in order to facilitate the fine adjustment of the inclination angle of the diagonal brace, each square steel column will be provided with two upper mounting holes and two lower mounting holes, and the above four mounting holes are arranged in a vertical row.

[0005] Under normal circumstances, the left and right brackets of the steel support are parallel to each other; but in actual construction, the edge of the top floor slab is often not a regular straight edge, and often has curved edges, beveled edges, corners, etc., so the left and right brackets are often forced to adjust and become non-parallel. Figure 1In the situation shown, when viewed from above, two perpendicular hanging baskets appear at the corner of the top floor. The right bracket 102 of the No. 1 hanging basket 101 is normally perpendicular to the lower edge 103 of the floor, but the left bracket 104 is 45 degrees to the lower edge. Similarly, the upper bracket 105 of the No. 2 hanging basket 108 is normally perpendicular to the left edge 106 of the floor, but the lower bracket 107 is 45 degrees to the left edge. Therefore, both hanging baskets have the left and right brackets as well as the upper and lower brackets that are not perpendicular.

[0006] Once the two brackets are not parallel to each other, a technical problem arises, that is, the two ends of the same diagonal brace will inevitably not be able to stick to the front side of the square steel column of the left bracket and the front side of the square steel column of the right bracket at the same time, nor can they stick to the rear side of the left and right square steel columns at the same time. In this way, after one end of the diagonal brace is first screwed with the square steel column on one side, the through hole at the other end of the diagonal brace will inevitably not be able to face the installation hole of the square steel column on the other side. The circumferential positions of the through hole and the installation hole are not uniform, resulting in the inability to screw. The conventional response idea in the industry is to punch a circle of multiple installation holes at different circumferential positions of the square steel column, but too many holes will greatly reduce the strength and shear resistance of the square steel column and thus reduce the overall firmness of the steel bracket, which is not worth the loss. Moreover, the angle between the rear fixed end of the diagonal brace and the front side of the corresponding square steel column is random and not fixed, and it is difficult to pre-punch the installation hole of the corresponding circumferential angle. Moreover, it is generally difficult to punch installation holes of other angles in the square steel section, so this idea cannot solve the above technical problems. Utility Model Content

[0007] The technical problem to be solved by the utility model is to provide a hanging basket adjustable height-increasing steel bracket which can firmly screw the two ends of the diagonal brace to the square steel columns of different brackets when the left and right brackets are not parallel.

[0008] The technical solution of the utility model is to provide an adjustable height-increasing steel bracket for a hanging basket, which includes two brackets on the left and right, each bracket includes a cantilever beam and a square steel column, the cantilever beam is installed with a traction rope for suspending the hanging basket through a pulley block, and two mutually intersecting diagonal braces are arranged between the same square steel columns of the left bracket and the right bracket; each square steel column is penetrated with two upper mounting holes and two lower mounting holes in the front-back direction, and each end of each diagonal brace is provided with a through hole;

[0009] A connecting piece is provided between each end of the diagonal brace and the corresponding square steel column. The connecting piece is composed of an upper sleeve, a central circular sleeve and a lower sleeve. The upper sleeve is provided with a transverse pin hole and is penetrated by a shear bolt. The lower sleeve is also provided with a transverse pin hole and is penetrated by a shear bolt. The connecting piece as a whole is penetrated by a vertical square hole. The square hole of the connecting piece covers the corresponding square steel column and the two shear bolts of the connecting piece are respectively screwed with the two upper mounting holes or the two lower mounting holes of the square steel column; the outer ring surface of the circular sleeve is provided with a radially concave annular groove, and a ring sleeve is rotatably fitted in the annular groove. A radially convex screw rod is welded to the ring sleeve, and the screw rod passes through the through hole at the corresponding end of the diagonal brace and is locked by a nut.

[0010] Compared with the prior art, the above-mentioned adjustable height-increasing steel bracket for hanging basket has the following advantages.

[0011] The bracket can make the assembly process of the diagonal brace and the corresponding square steel column convenient and quick. It only needs to insert the square hole of the connecting piece into the square steel column and screw the connecting piece and the square steel column with the shear bolt, then rotate the ring sleeve circumferentially to make the screw rod face the through hole at the end of the diagonal brace, and then pass the screw through the through hole and lock it with the nut; this solves the technical problems in the prior art that the through hole at the rear fixed end of the diagonal brace and the mounting hole of the square steel column are inconsistent in circumferential position, cannot be aligned, and cannot be screwed, ensuring that the two ends of the diagonal brace can be smoothly screwed with the square steel columns of the left and right steel frames regardless of any angle; moreover, since the upper and lower sleeves are firmly connected to the square steel column with the upper and lower shear bolts, in this way, the middle The ring sleeve is also firmly limited from the upper and lower directions, and the diagonal brace is also firmly connected to the ring sleeve through the screw rod. Therefore, the connection strength between the diagonal brace and the steel column of the steel bracket is firm and reliable, the shear resistance is excellent, and the overall strength and stability of the steel bracket are ideal; moreover, the present application does not add new holes on the square steel column, but uses the existing two groups of mounting holes to avoid frequent drilling to reduce or even destroy the strength of the square steel column; and the present structure makes good use of the characteristic that each group of mounting holes has two holes, and the upper hole of each group of mounting holes is screwed to the upper sleeve, and the lower hole is screwed to the lower sleeve, so that the ring sleeve is just stuck in the middle, and it is axially limited from the upper and lower directions to provide strong shear resistance.

[0012] In summary, the steel bracket of the present application is easy to install, has a firm connection after assembly, is reliable in shear resistance, does not add new installation holes, does not destroy the strength of the square steel column itself, and can install and fix the diagonal brace regardless of whether the left and right steel frames are parallel.
