Description
Technical Field
[0001] This utility model relates to the field of all-steel climbing scaffolding technology, specifically a simple, standardized passageway staircase device for all-steel climbing scaffolding. Background Technology
[0002] Currently, with the rapid development of the domestic construction industry, people have higher and higher requirements for safety and convenience in the construction process. The lifting scaffold has gradually transitioned from semi-steel scaffold to all-steel scaffold, but the technology still needs further improvement. For example, the connection between the upper and lower walkways of the all-steel climbing scaffold is generally not standardized. The connection channel between the upper and lower walkways of the climbing scaffold is crucial, mainly because in residential construction, in order to meet the construction schedule, the climbing scaffold process is used in conjunction with aluminum formwork process and prefabricated staircase process.
[0003] When workers are working on the working layer, the concrete pouring time at the bottom of the working layer usually does not meet the strength requirements for the installation of precast stairs. The staircase cannot be used as a connecting passage between the upper and lower floors. Workers can only enter the working layer through the all-steel climbing scaffold. There is no reliable connecting passage staircase. Workers can only climb to the working layer by hand. After the steel sections and steel plates come into contact with water and release agent, the surface becomes smooth, which poses a serious safety hazard. For example, a simple fixed-type passageway stair device for all-steel climbing scaffolding, disclosed in CN214576005U, can complete the erection of stairs by deforming the steel structure. However, when using this device, workers need to manually restrict the hinged parts with pins, which increases the workload for workers and makes it inconvenient for them to use.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-5As shown, a simple, standardized access staircase device for an all-steel climbing scaffold includes a support plate 1, two lower steel sections 3 and two upper steel sections 4, which are correspondingly arranged. Steel plate steps 6 are hinged to opposite sides of the two lower steel sections 3 and two upper steel sections 4. Several hinge rods 5 are fixed to the surface of the steel plate steps 6. The lower steel sections 3, upper steel sections 4, and steel plate steps 6 are hinged together by the hinge rods 5. Support hinge members 2 are hinged to both sides of the surface of the support plate 1, and the other end of the support hinge member 2 is hinged to the lower steel section 3. The device also includes: A binding assembly 7 is installed on the surface of the support plate 1 to bind the lower steel section 3 and the upper steel section 4 in the retracted state. A fixing mechanism 8 is installed in the inner cavity of the lower steel section 3 on one side and the upper steel section 4 on one side to limit the angle of the steel plate step 6. One end of the fixing mechanism 8 is provided with a reset component 10 for the auxiliary fixing mechanism 8.
[0016] The binding assembly 7 includes a mother magic bandage 71 fixed to one side of the surface of the support plate 1, and a daughter magic bandage 72 fixed to the other side of the surface of the support plate 1. The mother magic bandage 71 and the daughter magic bandage 72 work together to wrap around the surface of the lower steel 3, upper steel 4 and steel plate step 6 after they are retracted, thereby improving the stability after they are retracted.
[0017] The fixing mechanism 8 includes a pull plate 81 that slides within the cavities of a lower profile 3 and an upper profile 4 on one side, and a limiting hole 87 formed on the surface of a hinge rod 5. Several hinge plates 82 are hinged to the surface of the pull plate 81, and a limiting rod 83 is hinged to the other end of each hinge plate 82. A fixing plate 84 is fixed to the surface of the limiting rod 83. The fixing plate 84 is fixed to the corresponding cavity of the lower profile 3 or the upper profile 4. A first spring 85 is fixed to the surface of the fixing plate 84, and a fixing ring 86 is fixed to the other end of the first spring 85. The fixing ring 86 is fixed to the surface of the limiting rod 83. When the pull plate 81 is pulled, the hinge plates 82 hinged to the surface of the pull plate 81 can pull the limiting rod 83 under the restriction of the fixing plate 84, thereby causing the limiting rod 83 to disengage from the limiting hole 87. When the pull plate 81 is not under force, the fixing ring 86 can drive the limiting rod 83 to reset under the action of the first spring 85.
[0018] One end of the limiting rod 83 is fixed with a ball 9. The shape of the limiting hole 87 is complementary to the new shape formed by the limiting rod 83 and the ball 9. When the angle of the hinge rod 5 is a specified angle, the ball 9 facilitates the insertion of the limiting rod 83 into the limiting hole 87. Furthermore, the shape enhances the stability between the limiting hole 87 and the limiting rod 83.
[0019] A pull rod 11 is fixed to one end of the pull plate 81. The pull rod 11 is arched, providing a force point for the worker's hand and facilitating the pulling of the pull plate 81.
[0020] The reset assembly 10 includes a slide rod 102 that slides on both sides of one end of the pull plate 81. The other end of the slide rod 102 is fixed to the inner cavity of the lower steel section 3 or the upper steel section 4. A second spring 101 is sleeved on the surface of the slide rod 102. One end of the second spring 101 is fixed to the surface of the pull plate 81, and the other end of the second spring 101 is fixed to the inner cavity of the lower steel section 3 or the upper steel section 4. When the pull plate 81 slides, the slide rod 102 can restrict the sliding of the pull plate 81, and the second spring 101 can provide a limiting force for the reset of the pull plate 81.
[0021] Working principle: In use, the support plate 1 is placed on the ground, and then one end of the lower steel 3 is raised, so that the support hinge 2 is in an inclined state. When one end of the lower steel 3 is raised to the required height, the other end of the lower steel 3 contacts the ground. Then, under the action of the lower steel 3, the support hinge 2 and the ground, a stable triangular support structure is formed. It should be noted that the hinge method of the support hinge 2 is existing technology and will not be described in detail here. Thus, the purpose of supporting the lower steel 3 is achieved by using two support hinges 2.
[0022] After the lower steel section 3 is stabilized, the upper steel section 4 can be moved. The steel plate step 6 will then be selected around the hinge rod 5 as the axis. When the steel plate step 6 rotates to a horizontal angle, several limiting holes 87 and limiting rods 83 will be in corresponding positions. Then, under the action of the first spring 85 and the second spring 101, the limiting rods 83 and the ball 9 will be inserted into the limiting holes 87, so that the hinge rod 5 cannot rotate, thus achieving the purpose of fixing the steel plate step 6 and the upper steel section 4, thereby achieving the purpose of erecting the staircase.
[0023] When it is necessary to retract the lower steel section 3, the upper steel section 4, and the steel plate step 6, the worker can pull the pull rod 11 on the surface of the lower steel section 3 and the upper steel section 4, thereby causing the pull plate 81 to drive the hinge plate 82 to adjust its position. This allows the limiting rod 83 to disengage from the limiting hole 87 under the restriction of the fixed plate 84, and then the angle between the lower steel section 3, the upper steel section 4, and the steel plate step 6 can change, thus achieving the purpose of retraction.
[0024] After being folded up, the lower steel section 3, the upper steel section 4, and the steel plate steps 6 can be tied together using the pull rod 11.
