Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a conversion component of a cantilever scaffold. Background Art

[0002] During the construction of building cantilever scaffolding, after the wire rope is set, the top of the lower scaffolding and the supporting steel of the lower scaffolding can be separated by vertical force, so that the scaffolding under the supporting steel of the lower scaffolding can be removed. Before the wire rope is set, the steel of the upper scaffolding needs to be temporarily supported and fixed on the rod of the lower scaffolding, and then the upper scaffolding is installed on the steel. The outer end of the cantilever steel is temporarily supported on the lower scaffolding to ensure the safety of the upper scaffolding before the wire rope is set. When the upper scaffolding meets the unloading requirements, the wire rope is set to withstand the vertical force, so that the upper scaffolding can be completely separated from the lower scaffolding, so that the effect of segmented cantilevering can be achieved.

[0003] Since it is difficult to stably set the cantilever steel on the top of the lower scaffolding pole, the cantilever end of the upper scaffolding cantilever steel is usually set on the lower scaffolding crossbar to bear the force. Before the upper scaffolding is set with the steel wire rope, the force is transmitted from the upper scaffolding pole to the lower scaffolding crossbar, and then to the lower scaffolding pole through the crossbar fasteners of the lower scaffolding. Since the fasteners have low anti-slip ability, they are easy to slip when subjected to force, which poses a safety hazard of instability and deformation of the steel. Summary of the invention

[0004] The utility model aims to provide a conversion component of a cantilever scaffolding which has a simple structure, is easy to construct, safe and reliable, and can simultaneously meet the requirements of centering force transmission of upper and lower sections of the cantilever scaffolding uprights and stabilizing the cantilever steel and the lower suspension point setting of the wire rope.

[0005] The conversion component of the cantilever scaffolding of the utility model is realized as follows:

[0006] It includes a steel sleeve sleeved on the cantilever steel, a short column arranged on the steel sleeve for connecting the upper scaffolding uprights, a screw rod arranged below the steel sleeve for connecting the lower scaffolding uprights, a nut screwed on the screw rod, and a steel lifting ring arranged on the steel sleeve or the screw rod.

[0007] The outer diameter of the short column is basically matched with the inner diameter of the upper scaffolding upright pole, but is slightly smaller, and the height of the short column meets the requirements of inserting stability.

[0008] The nut can be freely adjusted up and down on the screw rod.

[0009] The screw rod and the short column core are in the same straight line, meeting the force transmission requirements of the upper and lower sections of the vertical rods.

[0010] The outer diameter of the screw rod matches the inner diameter of the scaffolding upright and is slightly smaller.

[0011] The steel sleeve is a rectangular steel sleeve, the inner dimensions of the steel sleeve match the outer dimensions of the cantilevered steel, and the rectangular steel sleeve meets the performance of transmitting force without deformation.

[0012] During construction, after the lower section scaffolding poles reach the predetermined erection height (preferably 200mm to 400mm below the cantilever steel), the conversion component of the cantilever scaffolding is placed on the lower section scaffolding poles, the screw rod is inserted into the pole, and the nut on the screw rod is rotated to adjust the elevation of the conversion component so that the bottom of the rectangular steel sleeve is slightly lower than the bottom of the cantilever steel, in preparation for the installation of the cantilever steel.

[0013] When installing cantilever steel, insert the cantilever steel one by one into the rectangular steel sleeve, rotate the nut on the screw rod to adjust the predetermined elevation of the cantilever steel, fix the other components of the cantilever steel, lower the nut on the screw rod so that the nut and the top of the lower section scaffolding upright are pressed and stressed to hold the cantilever steel tightly, then install the upper section scaffolding uprights on the short columns and add the upper section scaffolding, and transmit the force to the lower section scaffolding uprights through the conversion components.

[0014] When the upper section of the scaffolding meets the conditions for setting up wire ropes, the wire ropes are set up one by one. The upper ends of the wire ropes are connected to the structural steel rings on the building, and the lower ends are connected to the steel lifting rings on the rectangular steel sleeves and tightened.

[0015] After the wire rope is set, the nut on the screw rod is adjusted upwards to separate the vertical force of the cantilever steel and the lower scaffolding poles but not separate them, and the cantilever steel and the wire rope are combined to bear the force. At this time, the screw rod is still inserted in the lower scaffolding poles, in a virtual connection state, maintaining horizontal constraints, and completing the scaffolding heightening construction conversion.

[0016] During the construction process, if the scaffolding at the bottom of the cantilever steel is to be dismantled in advance due to special needs, since the cantilever steel and the lower scaffolding uprights are separated in vertical force, and the nut on the screw rod is far away from the upper end of the lower scaffolding upright, the scaffolding at the bottom of the cantilever steel can be directly dismantled. At this time, the outer wall of the building at the bottom of the cantilever steel is unfolded, that is, the conversion component of the cantilever scaffolding of the patent application can meet the demand that the scaffolding at the bottom of the cantilever steel can be dismantled in advance.

[0017] When dismantling the scaffolding from top to bottom in the normal way, after the frame is dismantled to the predetermined height, the nut on the screw rod is readjusted so that the nut is pressed against the top of the lower scaffolding upright and the force is transmitted to the lower scaffolding upright through the conversion component. The wire rope and the upper frame components of the steel section can be removed to complete the dismantling construction conversion of the upper and lower scaffolding.

[0018] Compared with the prior art, the utility model has the advantages of simple structure, convenient construction, safety and reliability, and can simultaneously meet the requirements of centering force transmission of upper and lower sections of cantilever scaffolding and stabilizing the cantilever steel and wire rope lower suspension point settings.

[0024] As shown in the figure, the conversion component of the door cantilever scaffolding of the utility model is realized as follows:

[0025] Embodiment 1: It comprises a rectangular steel sleeve 1 sleeved on the cantilever steel A, a short column 3 fixed on the steel sleeve 1 for connecting the upper scaffolding upright 2, a screw rod 5 fixed under the steel sleeve 1 for connecting the lower scaffolding upright 4, a nut 6 screwed on the screw rod 5, and a pair of steel lifting rings 7 fixed on the left and right sides of the steel sleeve 1.

[0026] The outer diameter of the short column 3 is substantially matched with the inner diameter of the upper scaffolding upright 2, but is slightly smaller, and the height of the short column 3 meets the requirements of stability when inserted.

[0027] The nut 6 can be freely adjusted up and down on the screw rod 5.

[0028] The screw rod 5 and the center of the short column 3 are in the same straight line, which meets the force transmission requirement of the upper scaffolding upright pole 2 and the lower scaffolding upright pole 4.

[0029] The outer diameter of the screw rod 5 matches the inner diameter of the lower scaffolding upright 4 and is slightly smaller.

[0030] A rectangular steel sleeve is used so that the inner dimensions of the steel sleeve match the outer dimensions of the cantilevered I-shaped cantilever steel A.

[0031] Example 2: Figure 3 As shown, this embodiment is based on the embodiment 1, and a pair of steel lifting rings 7 are fixed on the screw rod 5 on the left and right.

[0032] During construction, after the lower scaffolding upright 4 reaches the predetermined height (preferably 200mm to 400mm below the cantilever steel A), the conversion component of the cantilever scaffolding is placed on the lower scaffolding upright 4, the screw 5 is inserted into the lower scaffolding upright 4, and the nut 6 on the screw 5 is rotated to adjust the elevation of the conversion component so that the bottom of the rectangular steel sleeve 1 is slightly lower than the bottom of the cantilever steel A, in preparation for the installation of the cantilever steel A.

[0033] When installing the cantilever steel A, insert the cantilever steel A into the rectangular steel sleeve 1 one by one, rotate the nut 6 on the screw rod 5 to adjust the predetermined elevation of the cantilever steel A, fix the other components of the cantilever steel A, lower the nut 6 on the screw rod 5, so that the nut 6 and the top of the lower section scaffolding upright 4 are pressed and stressed to hold the cantilever steel A tightly, then install the upper section scaffolding upright 2 on the short column 3 and add the upper section scaffolding B, and transmit the force to the lower section scaffolding upright 4 through the conversion component.

[0034] When the upper scaffolding B meets the conditions for setting the steel ropes 8, the steel ropes 8 are set one by one, the upper ends of the steel ropes 8 are connected to the structural steel rings 9 on the building C, and the lower ends are connected to the steel lifting rings 7 on the rectangular steel sleeve 1 and tightened.

[0035] After the steel wire rope 8 is set, the nut 6 on the screw rod 5 is adjusted upward, so that the cantilever steel A and the lower scaffolding pole 4 are vertically separated but not separated, and the cantilever steel A and the steel wire rope 8 are combined to bear the force. At this time, the screw rod 5 is still inserted in the lower scaffolding pole 4, in a virtual connection state, maintaining horizontal constraint, and completing the scaffold B heightening construction conversion.

[0036] During the construction process, if the scaffolding B at the bottom of the cantilever steel A needs to be dismantled in advance due to special needs, since the cantilever steel A is separated from the lower scaffolding upright 4 by vertical force, and the nut 6 on the screw rod 5 is far away from the upper end of the lower scaffolding upright 4, the scaffolding B at the bottom of the cantilever steel A can be directly dismantled. At this time, the outer wall of the building at the bottom of the cantilever steel A is unfolded, that is, the conversion component of the cantilever scaffolding of the present patent application can meet the demand that the scaffolding B at the bottom of the cantilever steel A can be dismantled in advance.

[0037] When dismantling the scaffolding B from top to bottom in the normal way, after the frame is dismantled to a predetermined height, the nut 6 on the screw rod 5 is readjusted so that the nut 6 is pressed against the top of the lower scaffolding upright 4 and the force is transmitted to the lower scaffolding upright 4 through the conversion member, and the steel wire rope 8 and the upper frame member 10 of the cantilevered steel A can be dismantled to complete the dismantling construction conversion of the upper and lower scaffoldings B.
