Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
According to a first embodiment of the invention, a frustum-shaped building scaffold construction method is provided, which specifically comprises the following steps:
s102: as shown in fig. 1 and 2, after the fourth layer of roof 40 is poured and solidified, the scaffold 60 is integrally lifted to a first preset height;
s104: as shown in fig. 3, a wall-attached steel beam 70 is installed on the solidified fourth-layer ceiling 40 and connected to the lifting rail of the scaffold 60;
s106: as shown in fig. 4, after the wall-attached steel beams 70 of the first-layer roof panel 10 are removed, the scaffold 60 is lifted to a second preset height so that the bottom end of the scaffold 60 is flush with the upper surface of the first-layer roof panel 10;
s108: as shown in fig. 6, the fastening of the wall-attached steel beam 70 of the second-layer top plate 20 and the fastening of the wall-attached steel beam 70 of the fourth-layer top plate 40 are removed;
s110: as shown in fig. 7, the upper end of the scaffold 60 is driven by the first driving mechanism to deflect a first preset distance towards the building wall by using the wall-attached steel beam 70 of the third-layer roof 30 as a fulcrum;
s112: as shown in fig. 8, the fasteners of the wall-attached steel beam 70 of the third deck 30 are removed after the fasteners are installed on the wall-attached steel beam 70 of the fourth deck 40 to fix the wall-attached steel beam 70 of the fourth deck 40 again;
s114: as shown in fig. 9, the lower end of the scaffold 60 is driven by the second driving mechanism to deflect a second preset distance towards the building wall by using the wall-attached steel beam 70 of the fourth-layer roof 40 as a fulcrum, and the scaffold 60 is restored to the vertical state so that the distance between the scaffold 60 and the fifth-layer roof 50 to be poured meets the construction requirement;
s116: as shown in fig. 10, the fasteners are remounted on the wall-attached steel beams 70 of the second-layer roof panel 20 and the wall-attached steel beams 70 of the third-layer roof panel 30 to fix the wall-attached steel beams 70 of the second-layer roof panel 20 and the wall-attached steel beams 70 of the third-layer roof panel 30 again; after the fifth layer top plate 50 is poured and solidified, the process is circularly executed according to the steps;
in the construction method of the embodiment, as shown in fig. 1, the building area of each layer of top plate of the frustum-shaped building decreases gradually from bottom to top, that is, the whole building is of a forward frustum structure; when the scaffold 60 is in an initial state, the wall-attached steel beams 70 are installed on the first-layer top plate 10, the second-layer top plate 20 and the third-layer top plate 30 and are connected with the lifting rails of the scaffold 60, and the bottom end of the scaffold 60 is flush with the bottom plate of the frustum-shaped building, so that the construction of the first layer of the building is started; as shown in fig. 7, in the process of deflecting the upper end of the scaffold 60 toward the building wall by the first preset distance, the lower end of the scaffold 60 moves outward in the direction away from the building wall, and thus, in the process of deflecting the lower end of the scaffold 60 toward the building wall by the second preset distance to restore the scaffold 60 to the vertical state, the second preset distance is greater than the first preset distance. After the scaffold 60 inclines, the scaffold 60 receives a large bending stress, and in order to ensure the safety of the scaffold 60, the first preset distance needs to be smaller than a certain value, so that the scaffold 60 is prevented from inclining too much. In this embodiment, the first predetermined distance should be less than 10 cm. If the distance between the scaffold 60 and the fifth roof 50 to be poured cannot meet the construction requirement by adjusting the maximum distance by 10cm at a time, the distance between the scaffold 60 and the fifth roof 50 to be poured can be adjusted by repeatedly performing the steps S106 to S116 a plurality of times after the scaffold 60 is restored to the vertical state and fixed.
In the concrete implementation, as shown in fig. 1, the electric hoist 80 is adopted when the scaffold 60 is lifted, and the electric hoist 80 is installed in place before the fourth-layer roof 40 is poured. As shown in fig. 11, when the scaffold 60 is lifted to a first predetermined height, the electric block 80 is installed between the bottom end of the scaffold 60 and the wall-attached steel beam 70 of the first-story ceiling 10. Specifically, the electric hoist 80 is hung at a position close to the bottom end of the scaffold 60, a chain of the electric hoist 80 extends upward after passing through a sprocket mounted at the lower end of the lifting track of the scaffold 60, a hook of the electric hoist 80 is hung on the wall-attached steel beam 70 of the first-layer top plate 10, and the chain extending upward passes through the sprocket on the hook and then extends downward to be connected with the lower end of the lifting track of the scaffold, so that the scaffold 60 is lifted by a first preset height; as shown in fig. 12 and 13, when the scaffold 60 is lifted to the second predetermined height, the electric block 80 is installed between the bottom end of the scaffold 60 and the wall-attached steel beam 70 of the second-story ceiling 20. Specifically, the hanging position of the electric hoist 80 is unchanged, the hook of the electric hoist 80 is hung on the wall-attached steel beam 70 of the second-layer top plate 20, and the connection mode of the chain of the electric hoist 80 is also unchanged, so that the scaffold 60 is lifted to the second preset height. In this embodiment, the distance between the upper surfaces of two adjacent layers of roofs is 4.2 meters, the first preset height is 2 meters, and the second preset height is slightly greater than 2.2 meters, so that the scaffold 60 is prevented from being hindered by the second layer of roof 20 during lateral movement.
Further, in step S106 and step S108, after the scaffold 60 is lifted to the state that the bottom end is flush with the upper surface of the first-layer roof 10, the fastener of the wall-attached steel beam 70 of the second-layer roof 20 and the fastener of the wall-attached steel beam 70 of the fourth-layer roof 40 need to be removed, the whole scaffold 60 is fixed by only one pivot of the wall-attached steel beam 70 of the third-layer roof 30, the scaffold 60 is in an unfixed state from the position of the wall-attached steel beam 70 of the third-layer roof 30 to the top end and has a high height, and in order to prevent the scaffold 60 from falling to the outside, as shown in fig. 5, step S107 is further included between step S106 and step S108, and step S107 is specifically implemented by connecting the top end of the scaffold 60 with the wall-attached steel beam 70 of the fourth-layer roof 40 by using the diagonal tie; after the scaffold 60 is lifted to the bottom end and the upper surface of the first layer of roof 10 is flush, the top end of the scaffold 60 is fixed by the inclined drawknot 90, the scaffold 60 can be effectively prevented from toppling outwards, then the fastener of the wall-attached steel beam 70 of the second layer of roof 20 and the fastener of the wall-attached steel beam 70 of the fourth layer of roof 40 are dismantled, and the safety of the construction process can be effectively guaranteed.
In step S110, when the first driving mechanism is adopted to drive the upper end of the scaffold 60 to deflect a first preset distance towards the building wall, specifically, the first driving mechanism comprises a chain block and a pushing device, the chain block is arranged on the fourth layer top plate 40, the chain block is fixedly arranged on the fourth layer top plate 40 through a connecting piece, and a hook of the chain block is hung on a lifting track of the scaffold 60; optionally, the pushing device may be a hydraulic jack or other hydraulic pushing mechanism, the pushing device is disposed on the second-layer roof 20, one end of the pushing device is fixedly connected to the second-layer roof 20, and the other end of the pushing device abuts against the lifting rail of the scaffold 60; during specific work, the chain block pulls the upper end of the scaffold 60 along the direction towards the building wall; the pushing device pushes the lower end of the scaffold 60 outwards along the direction far away from the building wall, so that the upper end of the scaffold 60 is driven to deflect towards the building wall through the mutual matching of the chain block and the pushing device.
Further, in step S114, when the second driving mechanism is adopted to drive the lower end of the scaffold 60 to deflect a second preset distance towards the building wall, the second driving mechanism includes a chain block, the chain block is arranged on the second-layer top plate 20, the chain block is fixedly mounted on the second-layer top plate 20 through a connecting piece, a hook of the chain block is hung on a lifting track of the scaffold 60, and the chain block pulls the upper end of the scaffold 60 along a direction towards the building wall, so that the scaffold 60 gradually returns to a vertical state.
