[0031] In order to conveniently adjust the positions of the horizontal formwork 11 and the longitudinal formwork 12, the horizontal support rod 22 and the longitudinal support rod 23 are all arranged in a retractable manner, the horizontal support rod 22 and the longitudinal support rod 23 are arranged in a staggered manner along the length direction of the vertical support rod 21 and perpendicularly to each other, a plurality of mounting pipes 211 are horizontally arranged on the vertical support rod 21 along the length direction of the vertical support rod 21, the number of the mounting pipes 211 is the same as that of the horizontal support rod 22 and the longitudinal support rod 23, the horizontal support rod 22 and the longitudinal support rod 23 at the same horizontal height are both symmetrically arranged in two, one end of the horizontal support rod 22 and the longitudinal support rod 23 is slidably mounted in the mounting pipe 211, the mounting pipe 211 is provided with a locking member 212 for fixing the horizontal support rod 22 and the longitudinal support rod 23, and in the embodiment, the locking member 212 is a bolt. The bolt penetrates through the side wall of the mounting pipe 211 and abuts against the horizontal support rod 22 and the longitudinal support rod 23 to fix the horizontal support rod 22 and the longitudinal support rod 23 on the mounting pipe 211, in use, the length of the horizontal support rod 22 and the longitudinal support rod 23 can be adjusted by loosening the horizontal support rod 22 and the longitudinal support rod 23 in the mounting pipe 211 through screwing the bolt, the distance between the two horizontal formworks 11 and the two longitudinal formworks 12 can be controlled, and the horizontal formwork 11 and the longitudinal formwork 12 can be tightly abutted against the side wall of the elevator shaft.

[0032] 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 side edges of the longitudinal foot template 121 abut on 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 abuts on the horizontal foot template 111 to make the horizontal foot template 111 abut on the elevator shaft side wall; when the longitudinal support rod 23 pushes the longitudinal template 12 to move towards the elevator shaft side wall, 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 towards the elevator shaft side wall, and when the horizontal template 11 and the longitudinal template 12 move towards the elevator shaft side wall, 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 towards the elevator shaft side wall, and when the horizontal template 11 and the longitudinal template 12 completely abut on the elevator shaft side wall, the longitudinal foot templates 121 make the horizontal foot templates 111 abut on the elevator shaft side wall.

[0033] 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 in the process of unfolding 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 abutting on the horizontal foot templates 111 is rotatably provided with a sliding shaft 122, the sliding shaft 122 abuts on and can roll on the horizontal foot templates 111, the longitudinal foot templates 121 contact the horizontal foot templates 111 through the sliding shaft 122, and the sliding shaft 122 can roll on the horizontal foot templates 111 in the moving process of the longitudinal foot templates 121, so as to reduce the friction force between the longitudinal foot templates 121 and the horizontal foot templates 111, and make the longitudinal foot templates 121 move more smoothly on the horizontal foot templates 111.

[0034] When installing, the support template 1 is only hung in the elevator shaft by the electric hoist, and the support template 1 is prone to sliding during installation, which causes great trouble to installation. In order to avoid the support template 1 from shaking during installation, a plurality of fixing rods 4 are arranged at the bottom end of the support template 1 in the horizontal direction. In the embodiment, two fixing rods 4 are arranged and parallel to each other. The two fixing rods 4 enter the elevator shaft opening, one end is fixed on the side wall of the elevator shaft, and the other end extends to the floor and is fixed on the floor. When hoisting the support template 1, the height of the support template 1 is higher than the floor of the elevator shaft opening. After the fixing rods 4 are installed, the support template 1 is placed on the fixing rods 4. The fixing rods 4 can support the support template 1, avoid the support template 1 from shaking during installation, and make installation more convenient.
