Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and specifically relates to a sleeve-free aluminum template reinforcement device. Background Art

[0002] During the concrete pouring process, the building formwork is a temporary support structure that allows the concrete structure and components to be formed into the specified position and geometric dimensions. Therefore, the building formwork needs to be reliably reinforced before the concrete is poured. Currently, the most commonly used building formwork is aluminum alloy formwork. In the existing technology, the reinforcement of aluminum alloy formwork is usually a screw system, using a high-strength screw + sleeve + high-strength nut*2 + gasket*2 for construction. During the formwork installation and construction process, it is necessary to first install the sleeve on the formwork, and then insert the high-strength screw into the sleeve. The sleeve is disposable or reusable. Different sizes are selected to wrap the screw according to the wall thickness. Then the formwork is sealed. After the mold is sealed, the reinforcement system is formed by nuts, gaskets, and back ribs.

[0003] However, the above-mentioned existing aluminum formwork reinforcement method that requires the installation of sleeves has the problems of many assembly and disassembly steps and high labor intensity. In addition, if the sleeve is damaged during the pouring process, the screw cannot be removed and needs to be cut. The construction is difficult, time-consuming and labor-intensive, and it also affects the recycling of the screw, wastes resources and is costly. Utility Model Content

[0004] In order to solve or partially solve the problems existing in the related art, the utility model provides a sleeve-free aluminum formwork reinforcement device. The sleeve-free aluminum formwork reinforcement device is intended to solve the problems of the existing aluminum formwork reinforcement method that requires the installation of sleeves, such as many assembly and disassembly steps and high labor intensity, and the problem that if the sleeve is damaged, the screw cannot be removed, resulting in difficult construction, time-consuming and labor-intensive, wasteful resources, and high cost.

[0005] The present application provides a sleeve-free aluminum formwork reinforcement device, comprising:

[0006] A limiting screw rod is horizontally passed through the first and second templates. The limiting screw rod includes a polished rod section and a threaded section with threads, and all of the threaded sections are located outside the casting area between the first and second templates. A pin hole extending in the radial direction of the polished rod section is configured at the end of the polished rod section. The pin hole is a square hole. The outer end of the threaded section is configured with at least one positioning hole extending in the radial direction of the threaded section.

[0007] The first transverse back rib and the second transverse back rib are horizontally hung on the position of the limiting screw located on the outer side wall of the first template and the second template respectively;

[0008] A latch piece is inserted into the pin hole to tighten the first transverse back rib against the first template;

[0009] A locking nut and a washer, wherein the locking nut is detachably mounted on the threaded section of the limiting screw through a thread, and the locking nut presses the second transverse back rib against the second template through the washer;

[0010] The limiting buckle is inserted into the positioning hole to limit the locking nut.

[0011] In an optional solution, the length L2 of the polished rod section between the pin hole and the threaded section is not less than the distance L1 between the inner end face of the latch piece and the inner side wall of the second template, and not greater than the distance L3 between the inner end face of the latch piece and the inner side wall of the second transverse back rib.

[0012] In an optional solution, the extending directions of the pin hole and the positioning hole are parallel, and when the aluminum template is installed, the pin hole and the positioning hole are both arranged in a state of extending in the vertical direction.

[0013] In an optional solution, a tapered section is further provided on the end of the polished rod section of the limiting screw adjacent to the threaded section, and the diameter of the tapered section adjacent to the threaded section is larger than the diameter of the end away from the threaded section.

[0014] In an optional solution, the length L4 of the tapered section is not less than the width L0 of the casting area between the first formwork and the second formwork, and is not greater than the distance L5 between the inner sidewall of the first transverse back rib and the inner sidewall of the second transverse back rib.

[0015] Beneficial effects of the utility model:

[0016] The utility model adopts a limiting screw with a polished rod section and a threaded section to replace the threaded screw in the traditional reinforcement system, and the polished rod section replaces the role of the sleeve by making the concrete only contact with the polished rod section, thereby eliminating the steps of installing and removing the sleeve, and the limiting screw can be quickly taken out when the formwork is removed, effectively simplifying the steps of disassembling and assembling the aluminum formwork and reducing the difficulty of disassembly. At the same time, it effectively avoids the problem that the screw cannot be taken out if the sleeve is damaged in the traditional reinforcement system, effectively reducing the construction labor intensity, saving time and effort, and effectively improving the construction efficiency. The limiting screw is reusable, which can effectively reduce resource waste and improve economic benefits.

[0017] By installing the latch piece, the first transverse back rib is pressed against the first formwork and tightened, and by using the locking nut and gasket, the second transverse back rib is pressed against the second formwork and tightened, and by installing the limit buckle, the locking nut is limited, so that the latch piece and the limit buckle can form effective lateral support and positioning for the first formwork and the second formwork, which can effectively ensure the installation stability and positioning accuracy of the aluminum formwork, thereby ensuring the stability of the aluminum formwork during the concrete pouring process and the concrete forming quality.

[0036] The existing aluminum formwork reinforcement method that requires the installation of sleeves has the problems of many assembly and disassembly steps and high labor intensity. If the sleeve is damaged, the screw cannot be removed and needs to be cut. The construction is difficult, time-consuming and labor-intensive. It also affects the recycling of the screw, wastes resources and has high costs.

[0037] In response to the above problems, the present application makes improvements and innovations and proposes the following embodiments.

[0038] In one embodiment, see Figure 1 、 Figure 2 、 Figure 3 , provides a sleeve-free aluminum formwork reinforcement device, including: a limiting screw 1, the limiting screw 1 is horizontally penetrated on the first formwork 100 and the second formwork 200, the limiting screw 1 includes a polished rod section 11 and a threaded section 12 with a thread, and the threaded section 12 is entirely located outside the pouring area between the first formwork 100 and the second formwork 200, the end of the polished rod section 11 is configured with a pin hole 111 extending in the radial direction of the polished rod section 11, the pin hole 111 is a square hole, and the outer end of the threaded section 12 is configured with at least one positioning hole 121 extending in the radial direction of the threaded section 12; the first transverse back rib 2, the second transverse back rib The front rib 3, the first transverse back rib 2 and the second transverse back rib 3 are horizontally hung on the position of the limiting screw 1 at the outer wall of the first template 100 and the second template 200 respectively; the pin piece 4, the pin piece 4 is inserted in the pin hole 111 to tighten the first transverse back rib 2 to the first template 100; the locking nut 5 and the gasket 6, the locking nut 5 is detachably mounted on the threaded section 12 of the limiting screw 1 through a thread, and the locking nut 5 tightens the second transverse back rib 3 to the second template 200 through the gasket 6; the limiting buckle 7, the limiting buckle 7 is inserted in the positioning hole 121 to limit the locking nut 5.

[0039] In this way, by arranging the polished rod section 11 and the threaded section 12 with threads on the limiting screw 1, and making the threaded section 12 all outside the pouring area between the first formwork 100 and the second formwork 200 during the installation of the aluminum formwork, the poured concrete only contacts the polished rod section 11 with a smooth outer surface, thereby replacing the role of the sleeve with the polished rod section 11, and eliminating the use of the sleeve in the traditional reinforcement system. Specifically, during the installation and construction of the aluminum formwork, after the first formwork 100 and the second formwork 200 are positioned, a release agent is first applied to the bare rod section 11 of the limiting screw 1, and then the limiting screw 1 is passed through the second transverse back rib 3, the second formwork 200, the first formwork 100, and the first transverse back rib 2 in sequence, and it is ensured that the threaded section 12 is all located outside the casting area between the first formwork 100 and the second formwork 200, and then the latch piece 4 is inserted into the pin hole 111, and then the locking nut 5 and the gasket 6 are installed on the threaded section 12 and tightened, thereby pulling the limiting screw 1 to press the first transverse back rib 2 toward the first formwork 100 through the latch piece 4 and tighten it, and through the gasket 6 Press the second transverse back rib 3 toward the second template 200 and tighten it, thereby reinforcing the first template 100 and the second template 200, and then insert the limiting buckle 7 into the positioning hole 121 to limit the locking nut 5 through the limiting buckle 7, thereby further limiting the position of the locking nut 5 on the limiting screw 1, which can effectively ensure the stable installation of the locking nut 5; in this way, the first template 100 and the second template 200 can be effectively supported and positioned by the latch piece 4 and the limiting buckle 7, which can effectively ensure the installation stability and positioning accuracy of the aluminum template, thereby ensuring the stability of the aluminum template during the concrete pouring process and the concrete forming quality.

[0040] In this embodiment, a limit screw 1 constructed with a smooth rod section 11 and a threaded section 12 is used to replace the threaded screw in the traditional reinforcement system, and the smooth rod section 11 is used to replace the sleeve in a way that the concrete only contacts the smooth rod section 11. This can ensure that the limit screw 1 and other fasteners can effectively lock the aluminum formwork. At the same time, during the installation and construction of the aluminum formwork, the steps of installing and removing the sleeve can be omitted, and the limit screw 1 can be quickly removed when the formwork is removed, thereby effectively simplifying the steps of disassembling and assembling the aluminum formwork and reducing the difficulty of disassembly. At the same time, it effectively avoids the problem in the traditional reinforcement system that the screw cannot be removed if the sleeve is damaged, which can effectively reduce the construction labor intensity, save time and effort, and effectively improve construction efficiency. The limit screw 1 is reusable, which can effectively reduce resource waste and improve economic benefits.

[0041] In some embodiments, see Figure 1 、 Figure 2 、 Figure 3The length L2 of the polished rod section 11 between the pin hole 111 and the threaded section 12 is no less than the distance L1 between the inner end face of the latch plate 4 and the inner side wall of the second formwork 200, and no greater than the distance L3 between the inner end face of the latch plate 4 and the inner side wall of the second transverse back rib 3. This ensures, on the one hand, that after the aluminum formwork is installed, the entire threaded section 12 is located outside the pouring area between the first formwork 100 and the second formwork 200, ensuring that the poured concrete only contacts the polished rod section 11 with a smooth outer surface, thereby ensuring that the limiting screw 1 can be quickly removed during formwork removal. On the other hand, this ensures that the locking nut 5 and washer 6 have sufficient threaded installation area, ensuring that the locking nut 5 and washer 6 can accurately and reliably lock the limiting screw 1 and the aluminum formwork.

[0042] In some embodiments, see Figure 1 、 Figure 2 、 Figure 3 The extension directions of the pin hole 111 and the positioning hole 121 are parallel, and when the aluminum formwork is installed, the pin hole 111 and the positioning hole 121 are both arranged to extend in the vertical direction. In this way, during the installation and construction of the aluminum formwork, by arranging the limiting screw 1 with the pin hole 111 and the positioning hole 121 both extending in the vertical direction, the latch piece 4 and the limiting buckle 7 can be installed on the limiting screw 1 in a vertical downward position, thereby effectively improving the stability of the latch piece 4 and the limiting buckle 7 during the concrete pouring process, thereby ensuring the stability of the aluminum formwork during the concrete pouring process and the quality of the concrete forming.

[0043] In some embodiments, see Figure 1 、 Figure 2 、 Figure 4 The end of the polished rod section 11 of the limiting screw 1 adjacent to the threaded section 12 is further provided with a tapered section 13, and the diameter of the tapered section 13 adjacent to the threaded section 12 is larger than the diameter of the end facing away from the threaded section 12. Thus, by configuring the portion of the polished rod section 11 that contacts the concrete to be a frustum-shaped structure, the outer surface of the polished rod section 11 can be quickly separated from the concrete by striking the end of the polished rod section 11 of the limiting screw 1 during formwork removal. This ensures that the limiting screw 1 and other fasteners accurately and reliably lock the aluminum formwork, while further reducing the resistance of the concrete to the limiting screw 1 during formwork removal, thereby facilitating quicker removal of the limiting screw 1 and further improving formwork removal efficiency.

[0044] In some embodiments, see Figure 1 、 Figure 2 、 Figure 4The length L4 of the tapered section 13 is no less than the width L0 of the casting area between the first and second formworks 100, 200, and no greater than the distance L5 between the inner sidewalls of the first and second transverse back ribs 2, 3. This ensures that, after the aluminum formwork is installed, the portion of the polished rod section 11 of the limit screw 1 located within the casting area between the first and second formworks 100, 200 is entirely tapered section 13, ensuring that the portion of the polished rod section 11 in contact with concrete is entirely within the tapered section 13. Furthermore, the tapered section 13 is located between the inner sidewalls of the first and second transverse back ribs 2, 3, preventing the frustum-shaped structure of the tapered section 13 from interfering with the installation of the first and second transverse back ribs 2, 3.

[0045] Finally, it should be noted that although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can make changes, modifications, replacements and variations to the above embodiments within the scope of the present invention, which should all be included in the scope of protection of this application.
