Description

Technical Field

[0001] This invention belongs to the field of reaction equipment technology, and in particular relates to an impact-resistant aluminum formwork for buildings. Background Technology

[0002] The main types of formwork used in the construction industry include wooden formwork, steel formwork, plastic formwork, and aluminum formwork. Aluminum formwork has been widely used in the construction industry today due to its advantages such as convenient and quick installation and dismantling, strong load-bearing capacity, high safety and stability, high construction efficiency, high recycling value, and environmental friendliness.

[0003] The existing patent publication number CN113931437A discloses an impact-resistant building aluminum formwork, in which a frame composed of a horizontal frame, a first side frame, a second side frame, a first fixed frame, and a second fixed frame can strengthen the strength of the formwork and improve its impact resistance.

[0004] Although the aforementioned aluminum formwork can improve impact resistance when assembled and lock adjacent panels through a docking and locking mechanism, the assembly and locking method of this aluminum formwork results in a relatively fixed angle. It cannot be adjusted according to actual needs and is only suitable for pouring straight concrete, not for pouring curved concrete. This limits the application environment of the aluminum formwork, reduces the effectiveness of the assembled formwork, and fails to meet the usage requirements. Summary of the Invention

[0005] In view of the above-mentioned problems in the prior art, the present invention aims to provide an impact-resistant aluminum formwork for construction, which solves the problem that the angle of the aluminum formwork is fixed due to the assembly and locking method in the prior art, resulting in great limitations in its use.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0007] An impact-resistant aluminum formwork for construction is provided, comprising at least two aluminum formwork panels, wherein two hinge seats are spaced apart on one side wall of each aluminum formwork panel, and hinge blocks are provided on the other side wall.

[0008] The two hinge seats are respectively provided at the top and bottom of the aluminum film plate body, and the hinge block is provided between the two hinge seats. Each hinge seat is provided with a connecting pin, and each connecting pin passes through the hinge seat and connects to the hinge block.

[0009] An angle-assisted positioning device is provided between two adjacent aluminum film panels to fix the included angle between them.

[0010] Furthermore, each of the aluminum film panels has a reinforcing rib assembly on its back side.

[0011] Furthermore, each of the aluminum film panels has a support plate at the top and bottom of its back side.

[0012] Furthermore, the height of each of the hinge blocks is equal to the distance between the two hinge seats.

[0013] Furthermore, one side wall of each hinge block has an arc-shaped structure; an arc-shaped mounting groove is recessed on one side wall of the aluminum film plate body, and the arc-shaped side wall of each hinge block is located in the mounting groove.

[0014] Furthermore, a locking track component for cooperating with the angle auxiliary positioning device is horizontally provided in the middle of the back side of each aluminum film plate body;

[0015] The locking track component includes a fixing box with a closed rectangular cross-section. The bottom surface of the fixing box is fixedly connected to the back of the aluminum film plate body. The fixing box is arranged in a horizontal direction.

[0016] A long groove is provided in the middle of the top surface of the fixing box along its own length direction. A locking nut is provided inside the fixing box. The locking nut slides along its length direction inside the fixing box but cannot be rotated.

[0017] The angle-assisted positioning device includes a first locking arm and a second locking arm. The ends of the first locking arm and the second locking arm are rotatably locked together. The rotation direction of the first locking arm and the second locking arm is the same as the angle adjustment direction of the two adjacent aluminum film plates.

[0018] The free ends of the first and second locking arms are each provided with a locking screw. The two locking screws pass through the long slots in the fixing boxes on the two adjacent aluminum film plates and are threaded to the two locking nuts respectively.

[0019] Furthermore, both the first locking arm and the second locking arm are provided with connecting parts at their ends. Both connecting parts are semi-circular plate-shaped structures, and each connecting part has a connecting hole at its center. The two connecting parts are fixed opposite each other, and the two connecting holes of the two connecting parts overlap. Bolt locking elements are provided in the two overlapping connecting holes. The contact surfaces of the two connecting parts are provided with multiple locking serrations, and the multiple locking serrations are arranged in a ring along the center line of the connecting part.

[0020] Furthermore, friction plates are provided on the inner top surface of each of the fixing boxes and the upper end surface of the locking nut.

[0021] Furthermore, each of the locking nuts is a hexagonal nut, the thickness of the locking nut is less than the internal height of the fixing box, the width of the locking nut is less than the internal width of the fixing box, and the diagonal length of the locking nut is greater than the internal width of the fixing box.

[0022] The beneficial effects of this invention are as follows: The impact-resistant aluminum formwork of this invention, by setting hinge seats and hinge blocks on the main body of the aluminum formwork, realizes the connection of multiple main bodies of aluminum formwork while also realizing the adjustment of the included angle between two adjacent main bodies of aluminum formwork, meeting the actual use needs of building aluminum formwork that require changing the included angle; after the included angle between two adjacent main bodies of aluminum formwork is adjusted, the angle auxiliary positioning device will more firmly stabilize the included angle between the two adjacent main bodies of aluminum formwork, thereby improving the impact resistance of the building aluminum formwork.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0034] like Figures 1-6 As shown, this embodiment provides an impact-resistant building aluminum formwork, which includes at least two aluminum film plate bodies 1. Each aluminum film plate body 1 has two hinge seats 2 spaced apart on one side wall and hinge blocks 3 on the other side wall.

[0035] The two hinge seats 2 are respectively provided at the top and bottom of the aluminum film plate body 1. The hinge block 3 is provided between the two hinge seats 2. Each hinge seat 2 is provided with a connecting pin 4. Each connecting pin 4 passes through the hinge seat 2 and connects to the hinge block 3.

[0036] An angle auxiliary positioning device 5 is provided between two adjacent aluminum film panels 1 to fix the included angle between the two adjacent aluminum film panels 1.

[0037] Preferably, but not limited to, the height of each hinge block 3 is equal to the distance between the two hinge seats 2. This arrangement allows the hinge block 3 to fill the gap between the two hinge seats 2, resulting in better concrete pouring quality for the entire impact-resistant building aluminum formwork panel and reducing concrete pouring quality defects.

[0038] In this embodiment, during the construction of the impact-resistant aluminum formwork, the hinge block 3 on the current aluminum formwork body 1 and the hinge seat 2 on the next aluminum formwork body 1 are fixed with connecting pins 4. After the two adjacent aluminum formwork bodies 1 are fixed, the included angle between them can be adjusted by rotating the two adjacent aluminum formwork bodies 1 to meet the actual usage requirements of the building aluminum formwork to change the included angle. When the included angle between the two adjacent aluminum formwork bodies 1 is adjusted to the preset angle, it can be pre-fixed by tightening the connecting pins 4, and then the angle auxiliary positioning device 5 is set between the two adjacent aluminum formwork bodies 1, which can improve the impact resistance of the overall building aluminum formwork.

[0039] Specifically, such as Figure 1As shown, each of the aluminum film panel bodies 1 has a reinforcing rib assembly 6 on its back side. The reinforcing rib assembly 6 can be a fork-shaped structure composed of steel bars. It can be fixed to the back side of the aluminum film panel body 1 by welding. The reinforcing rib assembly 6 is used to strengthen the structural strength of the aluminum film panel body 1 and improve its impact resistance.

[0040] In this embodiment, each aluminum film sheet body 1 is provided with a support plate 7 at the top and bottom of its back side. The purpose of the support plate 7 is to facilitate the stacking of multiple aluminum film sheet bodies 1 and to facilitate the centralized collection and sorting of multiple aluminum film sheet bodies 1.

[0041] In this embodiment, as Figure 4 As shown, as a preferred arrangement of the hinge seat 2 and the hinge block 3, one side wall of each hinge block 3 has an arc-shaped structure; an arc-shaped mounting groove 8 is recessed on one side wall of the aluminum film plate body 1, and one side wall of each hinge block 3 with an arc-shaped structure is located in the mounting groove 8.

[0042] The above-mentioned arrangement can fill the gap in the length direction between the hinge block 3 and one side wall of the aluminum formwork body 1, further improving the concrete pouring quality of the entire impact-resistant building aluminum formwork and reducing concrete pouring quality defects.

[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, as a specific scheme for fixing the included angle between two adjacent aluminum film plate bodies 1 by the angle auxiliary positioning device 5, a locking track 9 is horizontally arranged in the middle of the back of each aluminum film plate body 1 for cooperating with the angle auxiliary positioning device 5.

[0044] The locking track component 9 includes a fixing box 10 with a closed rectangular cross-section. The bottom surface of the fixing box 10 is fixedly connected to the back of the aluminum film plate body 1, and the fixing box 10 is arranged in a horizontal direction.

[0045] A long groove 11 is provided in the middle of the top surface of the fixing box 10 along its own length direction. A locking nut 12 is provided inside the fixing box 10. The locking nut 12 slides along its length direction inside the fixing box 10 but cannot rotate.

[0046] Specifically, as a specific arrangement for the locking nut 12 to slide along its length direction but not rotate within the fixing box 10, each locking nut 12 is a hexagonal nut, the thickness of the locking nut 12 is less than the internal height of the fixing box 10, the width of the locking nut 12 is less than the internal width of the fixing box 10, and the diagonal length of the locking nut 12 is greater than the internal width of the fixing box 10.

[0047] The angle-assisted positioning device 5 includes a first locking arm 13 and a second locking arm 14. The ends of the first locking arm 13 and the second locking arm 14 are rotatably locked together. The rotation direction of the first locking arm 13 and the second locking arm 14 is the same as the angle adjustment direction of the two adjacent aluminum film plate bodies 1.

[0048] The free ends of the first locking arm 13 and the second locking arm 14 are each provided with a locking screw 15. The two locking screws 15 pass through the long slots 11 in the fixing boxes 10 on the two adjacent aluminum film plates 1 and are threaded to the two locking nuts 12 respectively.

[0049] The angle-assisted positioning device 5 fixes the included angle between two adjacent aluminum film plate bodies 1 as follows: First, the locking screws 15 on the free ends of the first locking arm 13 and the second locking arm 14 are respectively passed through the elongated grooves 11 on the two adjacent aluminum film plate bodies 1. Then, the locking screws 15 and the locking nuts 12 are pre-assembled. Next, the included angle between the two adjacent aluminum film plate bodies 1 is adjusted by rotating them. The included angle between the first locking arm 13 and the second locking arm 14 also changes accordingly. When the included angle between the two adjacent aluminum film plate bodies 1 is adjusted to the preset angle... Pre-fixing is achieved by tightening the connecting pin 4, then the ends of the first locking arm 13 and the second locking arm 14 are fixed, and the included angle between the first locking arm 13 and the second locking arm 14 is fixed. Finally, the locking screw 15 is tightened, and the locking screw 15 cooperates with the locking nut 12. The locking nut 12 moves upward in the fixing box 10 until the upper end face of the locking nut 12 abuts against the inner top surface of the fixing box 10, thus completing the fixing of the free ends of the first locking arm 13 and the second locking arm 14, and finally achieving the fixing of the included angle between the two adjacent aluminum film plate bodies 1.

[0050] Meanwhile, friction plates 20 are provided on the inner top surface of each fixing box 10 and the upper end surface of the locking nut 12. The upper end surface of the locking nut 12 is in close contact with the inner top surface of the fixing box 10, which can apply pressure to the friction plates 20 on both, increase the friction between the upper end surface of the locking nut 12 and the inner top surface of the fixing box 10, improve the fixing effect of the free ends of the first locking arm 13 and the second locking arm 14, and prevent the free ends of the first locking arm 13 and the second locking arm 14 from sliding.

[0051] Preferred, but not limited to, such as Figure 6As shown, in a specific embodiment of the ends of the first locking arm 13 and the second locking arm 14, both ends of the first locking arm 13 and the second locking arm 14 are provided with connecting portions 16. Both connecting portions 16 are semi-circular plate-shaped structures, and each connecting portion 16 has a connecting hole 17 at its center. The two connecting portions 16 are fixed opposite each other, and the two connecting holes 17 of the two connecting portions 16 overlap. Bolt locking elements 18 are provided in the two overlapping connecting holes 17. The contact surfaces of the two connecting portions 16 are provided with multiple locking serrations 19, and the multiple locking serrations 19 are arranged in a ring along the center line of the connecting portion 16.

[0052] When the included angle between two adjacent aluminum film panels 1 is adjusted, the included angle between the first locking arm 13 and the second locking arm 14 can be adjusted when the bolt locking part 18 is in the loose state, so as to match the included angle adjustment between the two adjacent aluminum film panels 1; when the bolt locking part 18 is in the locked state, the multiple locking serrations 19 on the contact surface of the two connecting parts 16 cooperate with each other to lock and fix the included angle between the first locking arm 13 and the second locking arm 14.

[0053] In summary, the impact-resistant aluminum formwork of this invention, by providing hinge seats 2 and hinge blocks 3 on the aluminum formwork body 1, enables the connection of multiple aluminum formwork bodies 1 while also allowing adjustment of the included angle between two adjacent aluminum formwork bodies 1, thus meeting the actual usage requirements of building aluminum formwork that need to change the included angle; after the included angle between two adjacent aluminum formwork bodies 1 is adjusted, the angle auxiliary positioning device 5 will more firmly stabilize the included angle between the two adjacent aluminum formwork bodies 1, thereby improving the impact resistance of the building aluminum formwork.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
