DETAILED DESCRIPTION

[0019] The embodiments of the present application will be described in detail below with specific reference to specific examples. Those skilled in the art can easily understand other advantages and effects of the present application from the disclosure of the present specification. The present application can also be implemented or applied by different specific embodiments, and various modifications or changes can be made to the details in the specification without departing from the spirit of the present application.

[0020] The following will be described in detail below with reference to the accompanying drawings. Figures 1-2Further details of the present application are provided below.

[0021] The elevator shaft and small space supporting device and construction method provided by the embodiments of the present application are described below with reference to the drawings. Figure 1 and Figure 2 The elevator shaft and small space supporting device comprises a supporting template 1 and a supporting assembly 2. The supporting template 1 comprises horizontal templates 11 and longitudinal templates 12. The horizontal templates 11 and the longitudinal templates 12 are arranged in pairs and in a vertical direction on the side walls of the elevator shaft. The supporting assembly 2 comprises vertical supporting rods 21, horizontal supporting rods 22 and longitudinal supporting rods 23 arranged on the vertical supporting rods 21 in a horizontal direction. In this embodiment, the horizontal supporting rods 22 and the longitudinal supporting rods 23 are each provided with three groups.

[0022] The two ends of the horizontal supporting rods 22 are arranged on the two horizontal templates 11 to abut the horizontal templates 11 against the side walls of the elevator shaft. The two ends of the longitudinal supporting rods 23 are arranged on the two longitudinal templates 12, and the two sides of the two longitudinal templates 12 abut against the two horizontal templates 11 to abut the two horizontal templates 11 against the side walls of the elevator shaft. In use, the device is transported to the position where the formwork is needed by using an electric hoist at the top of the elevator shaft. The horizontal templates 11 and the longitudinal templates 12 are tightly abutted against the side walls of the elevator shaft by the horizontal supporting rods 22 and the longitudinal supporting rods 23 to play a supporting role. The height of the device can be adjusted by the electric hoist to move the device to the position where the support is needed, which is more flexible and convenient to use.

[0023] In order to conveniently adjust the positions of the horizontal templates 11 and the longitudinal templates 12, the horizontal supporting rods 22 and the longitudinal supporting rods 23 are all arranged in a retractable manner. The horizontal supporting rods 22 and the longitudinal supporting rods 23 are arranged in a staggered manner along the length direction of the vertical supporting rods 21 and are arranged perpendicularly to each other. A number of mounting pipes 211 equal to the number of the horizontal supporting rods 22 and the longitudinal supporting rods 23 are arranged horizontally along the length direction of the vertical supporting rods 21. The horizontal supporting rods 22 and the longitudinal supporting rods 23 at the same horizontal height are both symmetrically provided with two rods. One end of the horizontal supporting rods 22 and the longitudinal supporting rods 23 is threadedly mounted in the mounting pipes 211. The ends of the horizontal supporting rods 22 and the longitudinal supporting rods 23 away from the vertical supporting rods 21 are rotatably arranged on the horizontal templates 11 and the longitudinal templates 12, respectively. The length of the horizontal supporting rods 22 and the longitudinal supporting rods 23 can be adjusted by rotating the horizontal supporting rods 22 and the longitudinal supporting rods 23, and the distance between the horizontal templates 11 and the longitudinal templates 12 arranged in pairs can be controlled.

[0024] In the installation of the device, by rotating the horizontal support rod 22 and the longitudinal support rod 23 respectively, the horizontal template 11 and the longitudinal template 12 can be moved to the side wall of the elevator shaft, and the horizontal template 11 and the longitudinal template 12 are tightly contacted on the side wall of the elevator shaft, which plays a supporting role for the elevator shaft. After use, the horizontal template 11 and the longitudinal template 12 are moved away from the side wall of the elevator shaft by rotating the horizontal support rod 22 and the longitudinal support rod 23, which facilitates the movement of the device to other positions for supporting or storage.

[0025] The longitudinal template 12 is hingedly provided with longitudinal foot templates 121 on both sides along the length direction of the longitudinal template 12, the length of the longitudinal foot template 121 is the same as the length of the longitudinal template 12, and the longitudinal foot template 121 can be folded on the longitudinal template 12, and the two sides of the longitudinal foot template 121 are in contact with the horizontal template 11. The horizontal template 11 is hingedly provided with horizontal foot templates 111 on both sides along the length direction of the horizontal template 11, the horizontal foot template 111 can be folded on the horizontal foot template 111, and the longitudinal foot template 121 is in contact with the horizontal foot template 111 for making the horizontal foot template 111 in contact with the side wall of the elevator shaft. When the longitudinal support rod 23 pushes the longitudinal template 12 to move to the side wall of the elevator shaft, the longitudinal foot templates 121 on both sides of the longitudinal template 12 can push the horizontal foot templates 111 on both sides of the horizontal template 11 to rotate to the side wall of the elevator shaft. During the movement of the horizontal template 11 and the longitudinal template 12 to the side wall of the elevator shaft, the longitudinal foot templates 121 can move on the horizontal foot templates 111, and at the same time, the horizontal foot templates 111 are pushed to the side wall of the elevator shaft. When the horizontal template 11 and the longitudinal template 12 are completely in contact with the side wall of the elevator shaft, the longitudinal foot templates 121 make the horizontal foot templates 111 in contact with the side wall of the elevator shaft.

[0026] At the same time, when the longitudinal foot templates 121 move on the horizontal foot templates 111, a large friction force is generated between the longitudinal foot templates 121 and the horizontal foot templates 111, so that the longitudinal foot templates 121 are difficult to move on the horizontal foot templates 111, resulting in a large resistance during the unfolding of the horizontal foot templates 111. In order to make the longitudinal foot templates 121 move more smoothly on the horizontal foot templates 111, the end of the longitudinal foot templates 121 in contact with the horizontal foot templates 111 is rotatably provided with a sliding shaft 122, the sliding shaft 122 is in contact with and can roll on the horizontal foot templates 111, the longitudinal foot templates 121 are in contact with the horizontal foot templates 111 through the sliding shaft 122, and the sliding shaft 122 can roll on the horizontal foot templates 111 during the movement of the longitudinal foot templates 121, which can reduce the friction force between the longitudinal foot templates 121 and the horizontal foot templates 111, so that the longitudinal foot templates 121 move more smoothly on the horizontal foot templates 111.

[0027] In order to avoid the longitudinal foot mould 121 moving out of the horizontal foot mould 111 during the moving process, the horizontal foot mould 111 is provided with a limiting plate 112 along the length direction of the horizontal foot mould 111 at the end of the horizontal foot mould 111 away from the horizontal mould plate 11, which is used to prevent the longitudinal foot mould 121 from sliding out of the horizontal foot mould 111, and when the horizontal foot mould 111 is fully unfolded and abuts against the sidewall of the elevator shaft, the end of the longitudinal foot mould 121 abuts against the limiting plate 112; meanwhile, the limiting plate 112 is vertically arranged on the horizontal foot mould 111 and can abut against the sidewall of the elevator shaft, so that the limiting plate 112 and the horizontal foot mould 111 are in a right angle state, and the connection between the limiting plate 112 and the horizontal foot mould 111 can just fit the corner of the sidewall of the elevator shaft.

[0028] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application, and all of them should be covered in the scope of the claims of the present application.
