All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1 and fig. 2, the embodiment of the present application provides a movable work platform for removing a formwork inside a hollow pier, the movable work platform includes a bearing platform 1, a sling 3 and an adjusting mechanism 4, the bearing platform 1 slightly smaller than the inside size of the pier body 6 is made of a shaped steel material according to the inside size of the pier body 6, and two ends of the bearing platform 1 are respectively provided with a plurality of connecting portions 10; one end of the sling 3 is connected to the connecting part 10, the other end of the sling is detachably connected to the formwork 2, and the sling 3 is further provided with an adjusting mechanism 4 for adjusting the distance between the two ends of the sling 3.
This application is connected the both ends of hoist cable 3 respectively on connecting portion 10 and pier shaft 6 in the template 2 of the superiors, through adjustment mechanism 4, adjust the interval between the both ends point of hoist cable 3, so that load-bearing platform 1 is located the below of the template 2 of lower floor, collide with load-bearing platform 1 when avoiding hanging out template 2, constructor stands on load-bearing platform 1, demolish and hang away the template 2 of lower floor, reuse adjustment mechanism 4 and promote load-bearing platform 1, reach upper template 2 departments, continue tearing open, therefore, can accomplish the interior template 2 of pier shaft 6 and demolish work.
Therefore, the method and the device provide safe and reliable operation space for constructors, reduce construction risks and have high popularization value.
When the movable operation platform is used, the movable operation platform is not in contact with poured concrete and has no damage to a pier body.
The movable operation platform is suitable for construction of various hollow piers and has wide application range.
In order to achieve adjustment of the distance between the two ends of the sling 3, in some preferred embodiments, detailed means are provided, see fig. 2, wherein the adjusting mechanism 4 is a chain block; the sling 3 comprises two cable sections 30, the chain block is positioned between the two cable sections 30, one end of each cable section 30 is connected with the connecting part 10 and the template 2, and the other end of each cable section 30 is connected with two hooks of the chain block. The operating personnel can realize the promotion and the transfer of load-bearing platform 1 through chain block, and after load-bearing platform 1 reachd preset position, chain block can also lock temporarily to guarantee that load-bearing platform 1 can not reciprocate.
Because the pouring of the hollow pier is usually one-section-by-one-section pouring, that is, after the pouring of the next section is completed, the formwork is removed, and then the pouring of the previous section is performed, when only one sling 3 is connected to the connecting part 10, after the formwork is removed from the lower section of the poured pier body 6 (the uppermost formwork 2 is not removed), when the upper section of the pier body 6 is poured and needs to be removed, the slings 3 need to be removed one by one from the uppermost formwork 2 of the lower section of the pier body 6, and then the upper section of the pier body is connected to the uppermost formwork 2 of the upper section of the pier body 6, so that the method is not very dangerous.
Therefore, in order to improve the safety factor and the stripping efficiency, the connecting part 10 is connected with two slings 3.
When the next pier body 6 is demolished, one of the two slings 3 is connected to the uppermost formwork 2 in the next pier body 6, after other formworks 2 except the uppermost formwork 2 are demolished, the inner formwork demolishing work of the pier body 6 is completed, the construction of the pier body 6 is performed, after the construction is completed, the other sling 3 is connected to the uppermost formwork 2 of the pier body 6, the original connection between the sling 3 and the uppermost formwork 2 of the next pier body 6 is released, the formwork is continuously demolished, and the pier body 6 is demolished piece by piece and layer by layer.
For the connection of the suspension cable 3, the connecting portion 10 may have various forms, such as, for example, a lifting lug, and as another example, a through hole may be formed in the edge portion of the carrying platform 1, so that the edge portion forms the connecting portion 10, and the suspension cable 3 may pass through the through hole and be tied to the carrying platform 1.
Referring to fig. 1, in order to make the load-bearing platform 1 more stable, two connecting portions 10 are respectively disposed at two ends of the load-bearing platform 1, and preferably, four connecting portions 10 are respectively located at four corners of the platform 1.
In order to facilitate the lifting out of the formworks from the slings after the formworks are removed, the slings 3 are connected to the abutted seams between the two adjacent formworks 2.
In order to prevent the tool from sliding off, referring to fig. 2, skirting boards 5 are arranged around the carrying platform 1. The height of the skirting board 5 is determined according to actual needs, and can be selected to be 20 cm-50 cm, for example.
Referring to fig. 1, the bearing platform 1 includes a transverse section steel 11, a longitudinal section steel 12, and a backing plate 13, the transverse section steel 11 and the longitudinal section steel 12 are welded to form a frame body, the backing plate 13 is laid on the frame body, and the backing plate 13 is made of a wood board or a steel wire mesh. Bearing platform 1 is formed by shaped steel welding, and simple structure can repeatedly be used, practices thrift the cost.
