A retractable lifting construction platform

technical field

The invention relates to a lifting construction platform, in particular to a retractable lifting construction platform.

Background technique

In the field of building construction, various types of scaffolding boards are widely used. Generally, there are many problems such as the use of more materials, long erection time, the height of the operating platform is not convenient for construction operations, and many hidden dangers in safe construction, especially in high-rise and super high-rise projects. more prominent. At present, in the construction of high-rise buildings, lifting construction platforms are generally used to move and transport some materials to each floor under construction. The elevating construction platform is a large self-elevating aerial work platform. It only needs to build a platform, and it can be lifted along the guide rail attached to the building through the lifting device. The platform runs smoothly. The staff can move the construction platform along the Lift to the ideal height along the guide rail. However, due to the influence of the main structure of the building, in the construction of high-rise buildings, the width of the entire scaffolding board needs to be manually adjusted during the lifting process of the construction platform. In the prior art, after the construction platform is assembled, since the size of the overall construction scaffolding around the outer wall is determined, it cannot change with the change of the outer wall, which requires the construction personnel to adjust the size of the scaffolding, another On the one hand, under the condition of ensuring the same construction progress, a large number of labor resources have to be used, which increases the labor intensity of individual construction personnel. In addition, the adjustment of this frame is not only complicated but also difficult.

As shown in Fig. 3, Fig. 4, Fig. 5, and Fig. 6, each of the scaffold boards 100 is provided with a first slide for the first telescopic scaffold board 101 or the second telescopic scaffold board 102 to move toward or back. Groove (not shown in the figure, omitted), the interior of the scaffolding board 100 is hollow, and the first chute is arranged on both sides along the inner length direction of the scaffolding board 101, that is, the first chute is parallel to the protective net frame 200; The first telescopic scaffold board 101 and the second telescopic scaffold board 102 are built in the hollow scaffold board 100 and can slide on the scaffold board 100 along the first chute. Each of the protective net frames 200 is also provided with a second chute (not shown in the figure, omitted) for the first telescopic protective net frame 201 or the second telescopic protective net frame 202 to move toward or backward. The first telescopic protective net frame 201 and the second telescopic protective net frame 202 can slide along the protective net frame 200 in the second chute. As shown in Figure 10, if the first telescopic scaffold board 101 of the scaffold board 100 on the frame body 1 and the first telescopic protective net frame 201 on the protective net frame 200 are connected to the same pole 300 On the parallel movable poles, the first telescopic scaffold board 101 and the first telescopic protective net frame 201 can slide synchronously along the respective chute under the action of the movable poles.

As shown in Figure 4, the construction platform also includes diagonal stay rods 400 fixedly connected with the scaffolding board 100 and the vertical rod 300 respectively, so as to enhance the overall stability of the scaffolding. There are many ways for the rod 300 to be fixedly connected, for example, buckle, pin or bolt. Each of said scaffold boards 100 is equipped with a rotating flap 104 away from the side of the protective net frame 200. When said rotating flap 104 is unfolded, the gap between the frame body and the wall can be reduced, and it is placed on the scaffold board 100 when folded. On the other hand, space can be saved, and there are many ways to connect the rotating replica 104, such as hinge connections.

In addition, a limiting device 105 is provided on the first chute in each of the scaffolding boards 100, and the limiting device 105 in the scaffolding board 100 is used to limit the first telescopic scaffolding board 101 and the second telescopic foot The sliding stroke of the hand board 102 in the first chute, the limiting device 105 for limiting the first telescopic scaffold board 101 and the second telescopic scaffold board 102 can be one or two, etc. Because described scaffold board 101 is inner hollow, therefore can install welding nut on the bottom or side channel steel of scaffold board 100, bolt is screwed into described weld nut and passes through bottom or side channel steel, and tightens described first The telescopic scaffolding board 101 or the second telescopic scaffolding board 102 prevents the first telescopic scaffolding board 101 or the second telescopic scaffolding board 102 from being pulled out, and acts as a limiter. The second chute in the protective net frame 200 is also provided with a limiting device (not shown in the figure, omitted) to limit the first telescopic protective net frame 201 or the second telescopic protective net frame 202 in the second slideway. The sliding stroke in the groove, the limiting device for limiting the first telescopic protective screen frame 201 and the second telescopic protective screen frame 202 can be one or two, etc., because the protective screen frame 200 is an internal control, and the side is mesh can install welding nuts on the side channel steel of the second chute, screw the bolts into the welding nuts and pass through the side channel steel, and tighten the first telescopic protective net frame 201 and the second telescopic protective net frame 201. The screen frame 202 prevents the first telescopic protection screen frame 201 and the second telescopic protection screen frame 202 from being pulled out, and acts as a limiter.

Further, guide rails (not shown in the figure, omitted) are connected to the first frame body 100, and the guide rails are fixedly connected to the first frame body 100 through connectors, and the guide rails are installed on the attached wall fixed on the wall. On the guide seat (not shown in the figure, omitted), under the action of the lifting device (not shown in the figure, omitted), the lifting of the guide rail and the first frame body 100 is realized. The specific structure and assembly of the wall-attached guide seat, guide rail and lifting device are prior art, and will not be repeated here.

In actual use, a plurality of frames 1 are generally used in connection, that is, the scaffolding boards 100 on the same plane on two adjacent frames 1 are connected, and at the same time, two adjacent frames 1 are connected to each other.
