Concrete leak-proof device and leak-proof aluminum formwork assembly

Abstract

A concrete leak-proof device comprises: a plurality of leak-proof plates, a pressing pad, and a plurality of holders. The leak-proof plates are arranged each other to touch an aluminum formwork and the ground at the same time, so that the leak-proof plates can cover an interval between the aluminum formwork and the ground. In addition, the pressing pad is arranged on several leak-proof plates, so that a boundary between every two leak-proof plates is covered by the pressing pad. The holders push the pressing pad to generate a holding force for affecting the leak-proof plates and the pressing pad, so that a friction between the ground and the leak-proof plates will increase for resisting the grouting pressure. Therefore, the leak-proof plates cannot move relative to the aluminum formwork in grouting operation, meanwhile the pressing pad can block the boundary without leaking grout.

Description

Technical Field

[0001] This invention relates to a concrete leak-proof device for building construction and a leak-proof aluminum formwork assembly thereof, particularly a concrete leak-proof device and a leak-proof aluminum formwork assembly that can prevent concrete from flowing out from the gap between the aluminum formwork and the floor. Prior Technology

[0002] In the foundation engineering of concrete buildings, construction workers first need to tie multiple steel bars into a steel structure. Then, the construction workers place multiple interconnected aluminum formworks along the outline of the steel structure, so that the multiple aluminum formworks together form a grouting space to accommodate the steel structure. Next, concrete is poured into the grouting space and waited for the concrete to solidify and take shape inside the grouting space, so that the concrete and the steel structure together form the walls or beams and columns of the building.

[0003] However, during the process of grouting concrete into the grouting space, the gap between the bottom surface of the aluminum formwork and the floor often causes concrete leakage, resulting in incomplete filling of the grouting space with concrete. Consequently, after the concrete solidifies, uneven joints will form on the surface of the walls or beams, affecting the aesthetics and even reducing the structural strength of the walls or beams. Summary of the Invention

[0004] The main objective of this invention is to improve the efficiency of grouting operations and the integrity of wall or beam-column structures. During grouting, concrete will not overflow from the gap between the bottom surface of the aluminum formwork and the floor, thereby preventing the formation of joints on the surface of the walls or beams and columns that could affect their structural strength. This reduces the risk of insufficient structural strength in the walls or beams and columns, thus improving the engineering quality and safety of the building.

[0005] The secondary objective of this invention is to improve the structural form of the concrete leak-proof device so that the boundary line between every two leak-proof connectors can be blocked, thereby effectively reducing the probability of concrete overflowing from the boundary line between every two leak-proof connectors during grouting operations.

[0006] To achieve the aforementioned objective, the present invention relates to a concrete leak-proof device, wherein the concrete leak-proof device is disposed between an aluminum formwork and a floor. The aluminum formwork has a grouting panel, a frame, and a baffle. The grouting panel and the baffle are respectively connected to adjacent sides of the frame. The frame is spaced apart from the floor to form a receiving space. The baffle is located inside the receiving space and spaced apart from the floor to form a gap. The concrete leak-proof device comprises: a plurality of leak-proof connectors, a pressure-bearing element, and a plurality of pushing mechanisms.

[0007] A plurality of the aforementioned leak-proof connectors are arranged adjacent to each other, such that a boundary line is formed between each pair of the aforementioned leak-proof connectors. Each of the aforementioned leak-proof connectors has a template contact portion located outside the aforementioned receiving space and a floor contact portion located inside the aforementioned receiving space. The template contact portion contacts the aforementioned baffle, and the floor contact portions are spaced apart and arranged directly below the aforementioned frame to contact the aforementioned floor, such that the plurality of the aforementioned leak-proof connectors together cover the aforementioned gap.

[0008] The aforementioned pressure-bearing element is disposed between the aforementioned floor contact portion and the frame, and can press downward against the plurality of aforementioned floor contact portions, so that the aforementioned pressure-bearing element can span across the aforementioned boundary line disposed at the aforementioned floor contact portion. The plurality of aforementioned pushing mechanisms are disposed at the aforementioned frame, and the aforementioned pushing mechanisms can push against the aforementioned pressure-bearing element to generate an anti-displacement force. The aforementioned anti-displacement force acts on the aforementioned floor contact portion and the pressure-bearing element to increase the friction between the aforementioned floor contact portion and the floor, so that the aforementioned template contact portion can avoid displacement relative to the aforementioned aluminum template through the aforementioned anti-displacement force.

[0009] In addition, the present invention relates to a leak-proof aluminum formwork assembly, comprising: an aluminum formwork and a concrete leak-proof device, wherein the aluminum formwork has a grouting panel, a frame and a baffle, the grouting panel and the baffle are respectively connected to adjacent sides of the frame, the frame is spaced apart from a floor to form a receiving space, and the baffle is located inside the receiving space and spaced apart from the floor to form a gap.

[0010] The aforementioned concrete leak-proof device comprises: a plurality of leak-proof connectors, a pressure-bearing element, and a plurality of pushing mechanisms, wherein the plurality of leak-proof connectors are arranged adjacent to each other such that a boundary line is formed between every two leak-proof connectors, and each leak-proof connector has a template contact portion located outside the aforementioned receiving space and a floor contact portion located inside the aforementioned receiving space, the template contact portion contacting the aforementioned baffle, and the floor contact portions being spaced apart and arranged directly below the aforementioned frame to contact the aforementioned floor, such that the plurality of leak-proof connectors together cover the aforementioned gap.

[0011] The aforementioned pressure-bearing element is disposed between the aforementioned floor contact portion and the frame, and can press downward against the plurality of aforementioned floor contact portions, so that the aforementioned pressure-bearing element can span across the aforementioned boundary line disposed at the aforementioned floor contact portion. The plurality of aforementioned pushing mechanisms are disposed at the aforementioned frame, and the aforementioned pushing mechanisms can push against the aforementioned pressure-bearing element to generate an anti-displacement force. The aforementioned anti-displacement force acts on the aforementioned floor contact portion and the pressure-bearing element to increase the friction between the aforementioned floor contact portion and the floor, so that the aforementioned template contact portion can avoid displacement relative to the aforementioned aluminum template through the aforementioned anti-displacement force.

[0012] In this embodiment, the pushing mechanism is provided with a fixed part disposed on the frame and a movable part that can move relative to the fixed part. The movable part can move relative to the fixed part to contact the pressure element.

[0013] In one embodiment, the fixed part is provided as two push nuts, and the movable part is provided as a push screw. The two push nuts are respectively located on opposite sides of the frame, and the push screw is screwed into the two push nuts and passes through the frame, so that the push screw can rotate relative to the frame and selectively approach or move away from the pressure element, thereby the push screw can contact the pressure element to form the anti-displacement force.

[0014] In another embodiment, the fixed part is provided with a C-shaped clamp and a template bolt, while the movable part is provided with a push bolt. The two ends of the C-shaped clamp are respectively provided with a clamping surface that can contact the frame and a template screw hole that can be screwed into by the template bolt. In the central section, there is a push screw hole that can be screwed into by the push bolt. The template bolt can rotate relative to the C-shaped clamp and approach the frame, so that when the template bolt contacts the frame, it can be clamped together with the C-shaped clamp to the frame. The push bolt can rotate relative to the C-shaped clamp and approach the pressure element, so that the push bolt can contact the pressure element and form the anti-displacement force.

[0015] In the two embodiments described above, the concrete leak-proof device further includes a leak-proof adhesive, which is applied to the boundary line between each pair of leak-proof connectors. The pressure-bearing element penetrates into the interior of the gap, so that the pressure-bearing element can press against the template contact portion, and the pressure-bearing element can cross the boundary line provided at the template contact portion.

[0016] The invention is characterized by a plurality of leak-proof connectors arranged adjacent to each other, with each leak-proof connector's template contact portion contacting the grouting panel of the aluminum template, such that the frame of the aluminum template and the template contact portion are located on opposite sides of the grouting panel. Simultaneously, the floor contact portion of each leak-proof connector contacts the floor, so that the plurality of leak-proof connectors cover the gap between the aluminum template and the floor. A plurality of pressure-bearing elements are disposed between the floor contact portion and the frame. The pushing mechanism, in contact with the pressure-bearing elements, generates an anti-displacement force acting on the floor contact portion and the pressure-bearing elements, thereby increasing the friction between the floor contact portion and the floor. During grouting, the template contact portion of the leak-proof connector continuously contacts the grouting panel through the concrete. Thus, the leak-proof connector, through the anti-displacement force, contacts the grouting panel with the template contact portion, preventing displacement relative to the aluminum template. This allows the leak-proof connector to prevent concrete from overflowing from the gap, thereby preventing the formation of joints on the surface of the wall or beam / column, which could affect the structural strength of the wall or beam / column. This relatively reduces the risk of insufficient structural strength of the wall or beam / column, thus improving the engineering quality and safety of the building.

[0017] Furthermore, when each leak-proof connector is in contact with both the floor and the aluminum formwork, the pressure-bearing element can simultaneously press against the floor contact portion and the formwork contact portion of the leak-proof connector. This allows the pressure-bearing element to span across the boundary line between the floor contact portion and the formwork contact portion. In this way, during grouting operations, the pressure-bearing element can prevent concrete from overflowing from the boundary line between each pair of leak-proof connectors.

Implementation

[0019] To facilitate a deeper and more detailed understanding of the structure, use, and features of the present invention, preferred embodiments are described below in conjunction with the accompanying drawings:

[0020] Please refer to Figures 1 and 2. In the first preferred embodiment, the leak-proof aluminum formwork assembly 1 of the present invention mainly consists of an aluminum formwork 10 and a concrete leak-proof device 20. The aluminum formwork 10 has a rectangular grouting panel 11, a ring-shaped frame 12, and an L-shaped baffle 13. The opposite sides of the grouting panel 11 are respectively provided as a forming surface 111 and a connecting surface 112. The forming surface 111 is used to contact a concrete 30, while the frame 12 is formed on the connecting surface 112. Furthermore, the frame 12 is spaced between a floor 40, such that a gap is formed between the frame 12 and the floor 40. The receiving space 50 is located directly below the frame 12. The baffle 13 is located inside the receiving space 50. The baffle 13 has a horizontal baffle 131 and a vertical baffle 132 arranged vertically on the horizontal baffle 131. The horizontal baffle 131 is connected to the frame 12, so that the grouting panel 11 and the baffle 13 are respectively connected to the adjacent sides of the frame 12. The surface of the vertical baffle 132 is flush with the forming surface 111. The lowest point of the vertical baffle 132 is spaced from the floor 40, so that a gap 60 close to the grouting panel 11 is formed between the lowest point of the vertical baffle 132 and the floor 40.

[0021] Please refer to Figures 1, 2 and 3. The concrete leak-proof device 20 has a plurality of leak-proof connectors 21, a plurality of pressure-bearing elements 22, a plurality of pushing mechanisms 23 and a plurality of fixing elements 24. The plurality of leak-proof connectors 21 are arranged adjacent to each other, such that a boundary line 211 is formed between each pair of leak-proof connectors 21. Each leak-proof connector 21 has a template contact portion 212 arranged longitudinally and a floor contact portion 213 arranged transversely. The template contact portion 212 is located outside the receiving space 50 and contacts the longitudinal stop portion 132 of the baffle 13. The floor contact portion 213 is located inside the receiving space 50, such that the floor contact portions 213 are spaced apart and arranged directly below the frame 12 to contact the floor 40. Thus, the plurality of leak-proof connectors 21 together cover the gap 60.

[0022] Furthermore, each pressure-bearing element 22 simultaneously contacts the floor contact portion 213 of a portion of the leak-proof connector 21, allowing the pressure-bearing element 22 to press downward against a plurality of floor contact portions 213. Consequently, a plurality of pressure-bearing elements 22 are disposed between the frame 12 of the aluminum template 10 and the floor contact portions 213. The pressure-bearing element 22 penetrates into the interior of the gap 60, allowing the pressure-bearing element 22 to press against the template contact portion 212 of the leak-proof connector 21. Consequently, the pressure-bearing element 22 can simultaneously span across the boundary line 211 of the template contact portion 212 and the boundary line 211 of the floor contact portion 213. In this embodiment, a portion of the pressure-bearing element 22 is located inside the receiving space 50 and is configured as a concealed portion 221, while the remaining portion of the pressure-bearing element 22 is located outside the receiving space 50 and is configured as an exposed portion 222.

[0023] A plurality of pushing mechanisms 23 are disposed on the frame 12 of the aluminum template 10. Each pushing mechanism 23 has a fixed portion 231 disposed on the frame 12 and a movable portion 232 movable relative to the fixed portion 231. The movable portion 232 can move relative to the fixed portion 231 to contact the pressure-bearing element 22, allowing the movable portion 232 to selectively contact or separate from the pressure-bearing element 22. In this embodiment, the fixed portion 231 is provided as two pushing nuts 231a, and the movable portion 232 is provided as a pushing screw 232a. The two pushing nuts 231a are respectively located on opposite upper and lower sides of the frame 12. On the side, the push screw 232a is screwed into the two push nuts 231a, and the push screw 232a passes through the frame 12, so that the push screw 232a can rotate relative to the frame 12 to selectively approach or move away from the inner part 221 of the pressure element 22. Each fixing element 24 passes through the floor contact part 213 of one of the leak-proof connectors 21, so that each fixing element 24 can be embedded in the floor 40, thereby preventing the leak-proof connector 21 from moving away from the aluminum template 10 by embedding it in the floor 40 through the fixing elements 24.

[0024] Please refer to Figure 4, which illustrates the specific application of the concrete leak-proof device 20 covering the gap 60 in the first preferred embodiment. First, a plurality of leak-proof connectors 21 are arranged adjacent to each other so that the template contact portion 212 and the floor contact portion 213 of the leak-proof connector 21 simultaneously contact the forming surface 111 of the aluminum template 10 and the floor 40, respectively, so that the plurality of leak-proof connectors 21 together cover the gap 60. Next, each pressure-bearing element 22 is placed between the frame 12 of the aluminum template 10 and the floor contact portion 213, so that the bottom surface of each pressure-bearing element 22 simultaneously presses against a portion of the floor contact portion 213 of the leak-proof connector 21, and each pressure-bearing element 22 penetrates into the gap 60, so that the side surface of each pressure-bearing element 22 simultaneously contacts a portion of the template contact portion 212 of the leak-proof connector 21. Thus, the pressure-bearing element 22 can span across the boundary line 211 of the template contact portion 212 and the boundary line 211 of the floor contact portion 213.

[0025] Finally, the pushing screw 232a of the pushing mechanism 23 rotates relative to the frame 12 of the aluminum template 10, so that the pushing screw 232a can approach the inner part 221 of the pressure-bearing element 22 until the pushing screw 232a contacts the pressure-bearing element 22. When the pushing screw 232a contacts the inner part 221, the pushing screw 232a generates a longitudinal anti-displacement force F. The anti-displacement force F can act on the floor contact part 213 and the pressure-bearing element 22 to increase the friction between the floor contact part 213 and the floor 40. This allows the template contact part 212 to avoid displacement relative to the aluminum template 10 through the anti-displacement force F. Thus, during the grouting operation, the template contact part 212 of the leak-proof connector 21 will continuously contact the grouting panel 11 through the concrete 30, causing the leak-proof connector 21 to contact the template contact part 212 with the grouting through the anti-displacement force F. Panel 11 prevents displacement relative to aluminum template 10, allowing leak-proof connector 21 to block concrete 30 from overflowing from gap 60. Simultaneously, pressure-bearing element 22 prevents concrete 30 from overflowing from the junction line 211 between every two leak-proof connectors 21, thereby preventing the formation of joints on the surface of walls or beams and columns, which would affect the structural strength of walls or beams and columns. This relatively reduces the risk of insufficient structural strength of walls or beams and columns, thus improving the engineering quality and safety of the building. In a preferred embodiment, to more reliably prevent concrete 30 from overflowing from the junction line 211 between every two leak-proof connectors 21, a leak-proof adhesive 70 is applied to the junction line 211 between every two leak-proof connectors 21 (as shown in Figure 2). Thus, when pressure-bearing element 22 simultaneously presses against template contact portion 212 and floor contact portion 213, the leak-proof adhesive 70 is located between leak-proof connector 21 and pressure-bearing element 22.

[0026] Please refer to Figures 5 and 6. In the second preferred embodiment, the difference from the first preferred embodiment lies in the pushing mechanism 23 of the concrete leak-proof device 20. As for the structure of the aluminum formwork 10, the leak-proof connector 21 of the concrete leak-proof device 20, and the pressure-bearing element 22 of the concrete leak-proof device 20, the structure is the same as that of the first preferred embodiment. Therefore, in this embodiment, the structure of the aluminum formwork 10, the leak-proof connector 21, and the pressure-bearing element 22 will not be described again.

[0027] Please refer to Figures 6 and 7. The fixed part 231 of the pushing mechanism 23 is provided with a C-shaped clamp 231b and a template bolt 231c, while the movable part 232 of the pushing mechanism 23 is provided with a pushing bolt 232b. The C-shaped clamp 231b has an upper clamping arm 231b1, a lower clamping arm 231b2, and a connecting arm 231b3. The end of the upper clamping arm 231b1 is formed with a template screw hole 231b4. The lower clamping arms 231b2 are spaced below the upper clamping arms 231b1, and the end of the lower clamping arm 231b2 is provided with a clamping surface 231b5 to contact the lower side of the frame 12 of the aluminum template 10. The connecting arm 231b3 is located between the upper and lower clamping arms 231b1 and 231b2, and is positioned above the exposed part 222 of the pressure-bearing element 22. b3 forms a push screw hole 231b6. In this embodiment, the C-shaped clamp 231b is disposed on the frame 12 of the aluminum template 10, such that the upper clamping arm 231b1 is located above the frame 12, and the lower clamping arm 231b2 is located below the frame 12. The template bolt 231c is screwed into the template screw hole 231b4, and the template bolt 231c can rotate relative to the C-shaped clamp 231b to approach the frame 12. When the template bolt 231c contacts the frame 12, the C-shaped clamp 231b and the template bolt 231c are clamped together on the frame 12. The push bolt 232b is screwed into the push screw hole 231b6, so that the push bolt 232b can rotate and move relative to the C-shaped clamp 231b. Thus, the push screw 232a can approach or move away from the exposed part 222 of the pressure element 22.

[0028] Please refer to Figure 8, which shows the specific application of the concrete leak-proof device 20 generated by the pushing mechanism 23 in the second preferred embodiment, which blocks the gap 60. When the template bolt 231c of the pushing mechanism 23 and the clamping surface 231b5 of the C-shaped clamp 231b simultaneously contact the upper and lower sides of the frame 12, the C-shaped clamp 231b and the template bolt 231c are clamped together in the frame 12. Next, the pushing bolt 232b of the pushing mechanism 23 rotates relative to the C-shaped clamp 231b and can approach the exposed part 222 of the pressure-bearing element 22. When the pushing bolt 232b can contact the exposed part 222 of the pressure-bearing element 22, the pushing bolt 232b can form an anti-displacement force F.
