[0032] The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0033] In the description of the embodiments of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "setting" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a communication between the internal parts of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood based on specific circumstances.
[0034] Reference Attachment Figures 1-6 The present embodiment provides a safe quick-disassembly tool for a multi-ribbed beam formwork, which includes a base 1, a top support 2 and several groups of side pull members 3. The top support 2 is arranged on the top of the base 1, and the side pull members 3 are connected to the side ends of the base 1 through a distance adjustment component 4. The distance adjustment component 4 can drive two groups of side pull members 3 located on the opposite side ends of the base 1 to move closer to or away from each other.
[0035] When the dense ribbed beam formwork 8 is to be removed, the side pulling members 3 are first connected to the inner side walls of the dense ribbed beam formwork 8, and the top support 2 is abutted against the inner top wall of the dense ribbed beam formwork 8, then the distance adjusting assembly 4 is started to reduce the distance between the side pulling members 3, thereby pulling the inner side walls of the dense ribbed beam formwork 8 towards the center of the dense ribbed beam formwork 8, so as to separate the outer side walls of the dense ribbed beam formwork 8 from the concrete, and then the whole tool is moved downward, so as to separate the outer top wall of the dense ribbed beam formwork 8 from the concrete. In this process, the top support 2 is always located below the inner top wall of the dense ribbed beam formwork 8 and slowly moves downward, so as to provide a certain bottom support for the dense ribbed beam formwork 8, and the side pulling members 3 are always connected to the dense ribbed beam formwork 8, so as to prevent the dense ribbed beam formwork 8 from falling and injuring people.
[0036] The dense ribbed beam formwork 8 can be quickly and non-destructively removed by using the tool and the above-mentioned use method, and the tool does not directly contact the concrete, so as to not damage the surface of the concrete.
[0037] The distance adjusting assembly 4 can be configured to include a driving rod 41, a first driven rod 42 and a second driven rod 43. The driving rod 41 is movably penetrated through the base 1 along the axial direction of the base 1. The proximal ends of the first driven rod 42 and the second driven rod 43 are rotationally connected, and the distal ends thereof are respectively rotationally connected to the driving rod 41 and the base 1. The side pulling members 3 are arranged at the connection ends of the first driven rod 42 and the second driven rod 43. By pulling the driving rod 41 along the axial direction of the base 1, the distance between the distal ends of the first driven rod 42 and the second driven rod 43 can be changed, and the connection ends of the first driven rod 42 and the second driven rod 43 will be close to or away from the base 1, so as to change the distance between the side pulling members 3. When the side pulling members 3 are close to each other, a pulling force is generated on the inner side walls of the dense ribbed beam formwork 8, so as to separate the outer side walls of the dense ribbed beam formwork 8 from the concrete.
[0038] In some more preferable embodiments, the first driven rod 42 is connected to the driving rod 41 through an adapter 5, the adapter 5 is rotatable about the axis of the driving rod 41, the other end of the driving rod 41 is screwed into a threaded sleeve 44 in the base 1, and the threaded sleeve 44 is fixedly arranged in the base 1. When the dense ribbed beam formwork 8 needs to be removed, one hand holds the base 1, and the other hand rotates the bottom end of the driving rod 41, so as to change the length of the bottom end of the driving rod 41 extending out of the base 1, thereby changing the distance between the distal ends of the first driven rod 42 and the second driven rod 43. In the use environment of the tool, compared with directly pulling the sliding driving rod 41, the threaded transmission is more labor-saving.
[0039] In implementation, the top support 2 can be arranged at the top end of the adapter 5, a ball bearing 6 is arranged in the adapter 5, the outer ring of the ball bearing 6 is fixedly connected to the adapter 5, and one end of the driving rod 41 extends into the ball bearing 6 and is fixedly connected to the inner ring thereof.
[0040] To improve the disassembly efficiency, the first driven rod 42 is arranged in the same number as the side pullers 3, and the first driven rods 42 are uniformly dispersed around the circumference of the driving rod 41, and the second driven rod 43 is arranged in the same number as the side pullers 3, and the second driven rods 43 are uniformly dispersed around the circumference of the base 1, so that the driving rod 41 can control the lateral movement of the plurality of side pullers 3 at the same time.
[0041] To improve the operation comfort, the bottom end of the driving rod 41 penetrates the base 1 and is connected to the rotating handle 7. The diameter of the rotating handle 7 is larger than that of the driving rod 41, and the outer shape of the rotating handle 7 can be configured according to actual needs to facilitate hand holding and rotating.
[0042] Reference is made to the accompanying drawings Figure 4 The side puller 3 extends in the radial direction of the driving rod 41, and the end of the side puller 3 away from the driving rod 41 is provided with a connecting hook 31. In the implementation, the manufacturer can be required to provide a hanging ring 81 on the inner side wall of the dense rib beam formwork 8 when the dense rib beam formwork 8 is ordered, so as to effectively connect the tool with the dense rib beam formwork 8.
[0043] The use method of the safety quick disassembly tool for the dense rib beam formwork includes the following steps:
[0044] (1) connecting the side puller 3 with the inner side wall of the dense rib beam formwork 8;
[0045] (2) abutting the top support 2 plate against the inner top wall of the dense rib beam formwork 8;
[0046] (3) moving the driving rod 41 in the axial direction of the base 1, so that the opposite ends of the first driven rod 42 and the second driven rod 43 are away from each other, and the two groups of side pullers 3 on the opposite ends of the base 1 separate the outer side wall of the dense rib beam formwork 8 from the concrete;
[0047] (4) moving the base 1 in the axial direction of the base 1, so that the outer top wall of the dense rib beam formwork 8 is separated from the concrete.
[0048] Compared with the prior art, the beneficial effects of the present application at least include that the distance adjusting assembly 4 can change the distance between the side pullers 3 to inwardly pull the inner side wall of the dense rib beam formwork 8 and drive the outer side wall to separate from the concrete, avoiding the damage to the concrete surface and the dense rib beam formwork 8 in the traditional method; and in the process of moving the tool downward, the top support 2 and the side puller 3 can always provide protection for the dense rib beam formwork 8 to prevent it from falling and injuring people, thereby improving the safety of the formwork construction.
[0049] The above is the preferred embodiment of the present application, and it should be pointed out that those skilled in the art can make some improvements and refinements without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
