Description

Technical Field

[0001] This invention relates to the field of concrete construction technology, and specifically to a pre-reserved hole formwork reinforcement device that is easy to dismantle. Background Technology

[0002] Reserving openings is a common construction task in all building processes, such as openings for pipe wells and maintenance openings. Traditionally, when supporting reserved openings, wooden formwork is used to create a frame the size of the opening, which is then fixed at the location of the reserved opening with nails and other means to ensure it is secure. After the concrete pouring is completed, the wooden frame is removed from the concrete reserved opening. However, because the reserved opening has fixed the wooden frame so firmly after pouring, it cannot be completely removed from the concrete reserved opening. Therefore, the wooden frame is usually forcibly broken and dismantled, and the removed wooden frame is basically all treated as construction waste, resulting in a significant waste.

[0036] The working principle of the above embodiments:

[0037] Currently, during support operations, wooden templates are used to create a frame the size of the opening, which is then fixed at the reserved opening location with nails and other reinforcements. After the concrete pouring is completed, the wooden frame is removed from the reserved concrete opening. However, because the reserved opening after pouring has fixed the wooden frame quite firmly, it cannot be completely removed from the reserved concrete opening. Therefore, the wooden frame is forcibly broken and dismantled, and the dismantled wooden frame is basically all treated as construction waste, resulting in a significant waste.

[0038] This embodiment provides a pre-reserved opening formwork reinforcement device that is easy to dismantle. It includes a front panel 1, a rear panel 3, a left panel 4, and a right panel 2, arranged in three sections. The middle panel 102 of the front panel 1, the middle panel 302 of the rear panel 3, the middle panel 402 of the left panel 4, and the middle panel 202 of the right panel 2 are all connected to a telescopic assembly. The middle panels 102 and 302 of the front and rear panels move towards or away from each other under the influence of the telescopic assembly, as do the middle panels 402 and 202 of the left and right panels. This device is used for supporting the pre-reserved opening. During construction, a fully unfolded, easily removable pre-reserved hole formwork reinforcement device is installed at the pre-reserved hole opening to await concrete pouring. After the concrete pouring is completed, the telescopic component drives the middle panel 102 of the front panel and the middle panel 302 of the rear panel to move in opposite directions, while simultaneously driving the middle panel 402 of the left panel and the middle panel 202 of the right panel to move in opposite directions. The easily removable pre-reserved hole formwork reinforcement device of this invention retracts, allowing the device to be completely removed from the pre-reserved hole opening. When the device needs to be used again, it can simply be fully unfolded again using the telescopic component. Compared with the prior art, the device provided in this embodiment can effectively improve construction operations, reduce construction waste, and increase construction efficiency.

[0039] Meanwhile, in this embodiment, the left and right sides of the middle assembly plate 102 of the front panel are both set as U-shaped structures with openings facing forward, the left and right sides of the middle assembly plate 302 of the rear panel are both set as U-shaped structures with openings facing backward, the front and rear sides of the middle assembly plate 402 of the left panel are both set as U-shaped structures with openings facing left, and the front and rear sides of the middle assembly plate 202 of the right panel are both set as U-shaped structures with openings facing right. This U-shaped structure can limit the right side of the left assembly plate 101 of the front panel, the left side of the right assembly plate 103 of the front panel, the right side of the left assembly plate 301 of the rear panel, the left side of the right assembly plate 303 of the rear panel, the rear side of the front assembly plate 401 of the left panel, the front side of the rear assembly plate 403 of the left panel, the rear side of the front assembly plate 201 of the right panel, and the front side of the rear assembly plate 203 of the right panel, so that there will be no relative displacement in the vertical direction between the various components of the device, thus ensuring the stability of the device.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Based on the technical essence of the present invention, any simple modifications, equivalent substitutions, and improvements made to the above embodiments within the spirit and principles of the present invention shall still fall within the protection scope of the present invention.
