Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a hinge type end-sealing mold structure. Background Art

[0002] In current construction, especially in the pouring of mid-slab structures, wooden formwork is widely used as end-capping formwork due to its low cost, smooth surface, light weight, low temperature resistance and easy processing. However, despite these obvious advantages, wooden formwork has the following defects in actual use, especially in end-capping operations:

[0003] 1. The durability of wooden formwork is relatively poor. After repeated use, especially after being soaked in water and exposed to the sun, wooden formwork is prone to deformation, cracking, and even warping, making it impossible to use it again and can only be treated as waste. This not only increases construction costs, but also causes unnecessary waste to the environment.

[0004] 2. The lack of a steel bar positioning structure at the end of the wooden formwork during the end sealing operation is another important defect. When pouring concrete, the spacing and position of the end steel bars are crucial to the safety and stability of the structure. However, since the wooden formwork itself does not have a special steel bar positioning structure, construction workers can only rely on experience and skills to position the steel bars, which can easily lead to inaccurate spacing and positioning of the steel bars, thus affecting the quality and safety of the structure.

[0037] See also Figures 1 to 6The embodiment of the utility model provides a hinge-type end-capping mold structure, including an upper template 1 and a lower template 2. The top of the upper template 1 is provided with a row of upper steel bar positioning notches 11 for positioning the upper end steel bars along its length direction, and the bottom of the lower template 2 is provided with a row of lower steel bar positioning notches 21 for positioning the lower end steel bars along its length direction. The top of the lower template 2 is rotatably connected to the bottom of the upper template 1 so that the upper template 1 and the lower template 2 can switch between a folded state and an unfolded state. When the upper template 1 and the lower template 2 are in the unfolded state, the concrete contacting side of the upper template 1 and the concrete contacting side of the lower template 2 are on the same plane, forming a complete end-capping mold. When the upper template 1 and the lower template 2 are in the folded state, their volume is greatly reduced, thereby saving storage space, which is very beneficial for space management on the construction site.

[0038] When in use, first unfold the upper template 1 and the lower template 2 from the folded state to ensure that they form a complete end-capping template on a plane; then, place the unfolded end-capping template at the position where the end needs to be capped, ensuring that its concrete-contacting side is in close contact with the concrete surface to be poured; secondly, place the upper end steel bar into the upper steel bar positioning groove 11 of the upper template 1, and place the lower end steel bar into the lower steel bar positioning groove 21 of the lower template 2 to ensure that the steel bar is accurately positioned; after pouring the concrete and curing it to a certain strength, remove the unfolded end-capping template from the concrete structure, fold it and store it in an appropriate location for next use.

[0039] The hinge-type end-sealing mold structure provided in this embodiment can ensure the accurate positioning of the end steel bars during the end-sealing process and improve the construction quality by setting the upper steel bar positioning groove 11 and the lower steel bar positioning groove 21 at the top of the upper mold 1 and the bottom of the lower mold 2; through the rotating connection setting of the upper mold 1 and the lower mold 2, the user can easily switch the mold between the folded state and the unfolded state, realize rapid end-sealing, rapid overall dismantling, and facilitate transportation and storage.

[0040] In one embodiment, the upper template 1 and the lower template 2 are both made of steel plates. This design brings the following advantages:

[0041] 1) High durability: The steel plate material has extremely high strength and durability, and can withstand various impacts and vibrations during the construction process, ensuring that the hinge-type end-capping mold structure can be repeatedly used for a long time without being easily damaged.

[0042] 2) Strong anti-deformation ability: The steel plate material has excellent anti-deformation ability. Even in long-term use and multiple loading and unloading processes, it can maintain its original shape and size, ensuring the accuracy and stability of the hinge-type end-capping mold structure.

[0043] 3) Easy to clean and maintain: The surface of the steel plate is smooth and not easy to adhere to concrete residues, which makes it easy to clean and maintain. At the same time, the steel plate material also has strong corrosion resistance and can maintain its stable performance in harsh environments such as humidity and dust.

[0044] 4) Accurate positioning of the end steel bars: Since the steel plate material has high processing accuracy and stability, the steel bar positioning notches on the upper template 1 and the lower template 2 can be accurately processed to ensure that the end steel bars can be accurately positioned during the end sealing process, thereby improving the construction quality.

[0045] 5) Environmentally friendly and sustainable: Steel plate materials can be recycled and reused, which meets the requirements of environmental protection and sustainable development. Compared with traditional wooden formwork, the hinged end-capped formwork structure has a longer service life and lower waste generation rate.

[0046] See also Figures 2 to 6 In one embodiment, the hinged end-capping mold structure further includes a template positioning steel bar 3, a first positioning steel plate 4 is provided on the non-contacting concrete side of the upper template 1, a first positioning hole 41 matching the template positioning steel bar 3 is provided on the first positioning steel plate 4, and a second positioning steel plate 5 is provided on the non-contacting concrete side of the lower template 2 at a position corresponding to the first positioning steel plate 4, and a second positioning hole 51 matching the template positioning steel bar 3 is provided on the second positioning steel plate 5. When the upper template 1 and the lower template 2 are unfolded from the folded state to the unfolded state, the template positioning steel bar 3 is inserted into the first positioning hole 41 on the first positioning steel plate 4 and the second positioning hole 51 on the second positioning steel plate 5, so that the upper template 1 and the lower template 2 can be locked in the unfolded state, so as to prevent the upper template 1 and the lower template 2 from rotating during the pouring process, resulting in the upper template 1 and the lower template 2 contacting concrete side not being on the same plane, thereby avoiding pouring quality problems caused by template movement or deformation, such as concrete leakage, irregular shape, etc.

[0047] The locking mechanism formed by the template positioning steel bars 3, the first positioning steel plate 4 and the second positioning steel plate 5 makes the installation and removal process of the template simpler and faster, and the construction personnel do not need to worry about the displacement or deformation of the template during the pouring process, thereby reducing unnecessary inspection and adjustment work. In addition, this design also allows the template to be quickly removed from the concrete structure after pouring, saving time for subsequent construction steps.

[0048] See also Figure 2 , Figure 5 , Figure 6In one embodiment, a first positioning steel plate 4 is provided at intervals on the non-contact concrete side of the upper template 1, and a second positioning steel plate 5 is provided at intervals on the non-contact concrete side of the lower template 2, and the first positioning steel plates 4 and the second positioning steel plates 5 correspond one to one. By providing the first positioning steel plates 4 and the second positioning steel plates 5 at intervals on the non-contact concrete sides of the upper template 1 and the lower template 2, and making these positioning steel plates correspond one to one between the upper template 1 and the lower template 2, the overall stability of the hinge-type end-capping mold structure can be significantly increased, making the template more stable when bearing concrete pressure, and reducing the possibility of deformation or movement of the template.

[0049] In one embodiment, the first positioning steel plate 4 is welded to the non-contact concrete side of the upper formwork 1, and the second positioning steel plate 5 is welded to the non-contact concrete side of the lower formwork 2. The first positioning steel plate 4 and the second positioning steel plate 5 are fixed by welding, which ensures a firm connection between the first positioning steel plate 4 and the upper formwork 1, and between the second positioning steel plate 5 and the lower formwork 2, making the formwork more stable when bearing concrete pressure, reducing the possibility of deformation or movement of the formwork, thereby improving the quality and safety of construction.

[0050] In one embodiment, the upper steel bar positioning notch 11 and the lower steel bar positioning notch 21 are both rectangular. The rectangular notch setting helps to ensure the stability and accuracy of the end steel bar during the pouring process. Among them, the width of the upper steel bar positioning notch 11 and the lower steel bar positioning notch 21 is slightly larger than the diameter of the end steel bar, so as to ensure that the end steel bar can be easily placed in the upper steel bar positioning notch 11 and the lower steel bar positioning notch 21, and at the same time prevent the end steel bar from shaking in the upper steel bar positioning notch 11 and the lower steel bar positioning notch 21.

[0051] See also Figures 1 to 6 In one embodiment, the hinge-type end-capping mold structure further includes an intermediate shaft core 6, a first shaft sleeve 12 is provided at the bottom of the non-contact concrete side of the upper template 1, and a second shaft sleeve 22 is provided at the top of the non-contact concrete side of the lower template 2, the first shaft sleeve 12 and the second shaft sleeve 22 are arranged alternately along the same straight line, and the intermediate shaft core 6 penetrates the first shaft sleeve 12 and the second shaft sleeve 22. Through the intermediate shaft core 6, the first shaft sleeve 12 and the second shaft sleeve 22 arranged as above, the top of the lower template 2 and the bottom of the upper template 1 are rotatably connected, so that the upper template 1 and the lower template 2 can be switched between the folded state and the unfolded state at will. At the same time, since the first shaft sleeve 12 and the second shaft sleeve 22 are arranged on the non-contact concrete side of the upper template 1 and the lower template 2, it can be avoided that the first shaft sleeve 12 and the second shaft sleeve 22 are in contact with the concrete when the upper template 1 and the lower template 2 are unfolded to the unfolded state for use.

[0052] Preferably, a plurality of first sleeves 12 are arranged at intervals at the bottom of the non-contact concrete side of the upper template 1, and a plurality of second sleeves 22 are arranged at intervals at the top of the non-contact concrete side of the lower template 2. The plurality of first sleeves 12 and the plurality of second sleeves 22 are arranged alternately along the same straight line, and the middle shaft core 6 is inserted alternately into the plurality of first sleeves 12 and the plurality of second sleeves 22. The above arrangement makes the connection stability between the upper template 1 and the lower template 2 higher, effectively prevents the template from being deformed or twisted when subjected to force, and ensures the accuracy and stability of the concrete structure.

[0053] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0054] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
