The other end of the structural main beam 21 is set on the floor 10 below the elevator entrance 2. The position where the structural main beam 21 connects to the support column 4 and the other end of the structural main beam 21 form a support extension section 8. By providing the first and second crossbeams, a three-dimensional construction platform frame can be easily formed.

[0031] Specifically, two first cross beams 12 and two second cross beams may be used.

[0032] Specifically, such as Figures 1 to 3 As shown, in this embodiment, there are two limit columns 5 and two support columns 4. Two limit columns and two support columns are used to facilitate the formation of a construction platform and the laying of scaffolding.

[0033] like Figures 1 to 3 As shown, a group of first beams 12 on the left side and a group of first beams 12 on the right side are arranged in a one-to-one correspondence, and the first beams 12 on the same horizontal plane form a beam laying layer, on which scaffolding boards 14 are laid.

[0035] like Figure 1 and Figure 2 As shown, the bottom beam laying layer is covered with scaffolding boards 14, and the remaining beam laying layers are laid with scaffolding boards 14 in the rear area. It is convenient for construction workers to step on the scaffolding boards to carry out construction operations.

[0036] like Figure 1 and Figure 2 As shown, the supporting columns 4 and the limiting columns 5 arranged in the front and rear correspondingly are connected and fixed by scissor braces 15. The scissor braces can stably connect and fix the supporting columns and the limiting columns.

[0037] like Figure 1 and Figure 2 As shown, in this embodiment, the lower end of the supporting column 4 and the lower end of the limiting column 5 are located in the same horizontal plane, the upper end of the supporting column 4 is higher than the upper end of the limiting column 5, and the upper end of the limiting column 5 exceeds the preset distance of the top first beam 12.

[0039] When in use, the wire rope on the hoist 9 can be passed through the hook 19 at the top of the elevator shaft 1 and connected to the elevator car 20 in the elevator shaft 1.

[0040] Specifically, during the construction phase of building decoration and renovation, the construction platform of this embodiment is placed on the top of the elevator shaft to complete the installation of the indoor elevator. The hoist of this embodiment has a lifting capacity of not less than 2t and can be purchased on the market. The hoist is fixed to the support extension section at the end of the construction platform and is mainly used for lifting during elevator installation. The main beam, cross beam and column of the construction platform are all made of 10# I-steel, and holes are punched on them for connecting the main beam, cross beam and column. Its performance is not lower than the relevant requirements in GB / T 706-2016. The scissors support is made of No. 5 channel steel, and holes are punched at both ends for connecting the cross beam. Its performance is not lower than the relevant requirements in GB / T According to the relevant requirements of 706-2016, the scaffolding board shall be a wooden scaffolding board with a width of 200mm and a thickness of 50mm. The top mechanism shall be a threaded structure with a base at one end and a turntable for self-adjustment of length at the other end. The mechanical properties shall not be lower than those specified in Q345 of GB / T1591. The main beam, cross beam, supporting columns, auxiliary columns, limit columns and scissors braces shall be connected with connecting bolts. The mechanical properties of the bolts shall not be lower than those specified in Q235 of GB / T 700. They shall be made of round steel with threaded thread. You can also purchase bolts that meet the requirements on the market. The bolt specification shall not be less than M16. When using this embodiment, there is no need for a scaffolding inside the elevator shaft. This embodiment can be assembled and installed to the position of the elevator door on the top floor of the elevator shaft according to the requirements of the drawings, and then the top-up mechanism is used to top up the elevator shaft wall (support wall) and the support column to make it stable and not loose. The limit column is stuck on the outer wall of the elevator shaft and forms a bidirectional force with the top-up mechanism to ensure the stability of the construction platform. When installing the elevator, the wire rope of the winch is passed through the reserved hook of the structure, and the wire rope is extended to the bottom of the elevator shaft to assist in the installation of the elevator. If the height of this device is insufficient, the main beam + cross beam + column method can be used to extend the required operating height of the construction platform (i.e., auxiliary extension bracket). During the installation period, the elevator extends to the top floor layer by layer as the wire rope shrinks. Scaffolding boards are laid on the cross beams of the construction platform for the installation personnel to work. They can be assembled by themselves to ensure safety during use. When the elevator is installed and lifted to the lower floor of the top floor, the device of this embodiment is removed and the elevator is used for installation instead. From then on, the elevator installation task is completed.

[0041] The scaffolding-free elevator installation and construction device of this embodiment can be flexibly arranged according to needs during the building decoration construction phase, and can solve and optimize the problem of indoor elevator installation without scaffolding. At the same time, it can also optimize the construction process, improve the construction technology level and the reliability and safety of the construction.
