DETAILED DESCRIPTION

[0035] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application are described in detail below with reference to the accompanying drawings. In the following description, a lot of specific details are set forth in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0036] In the description of the present application, it should be understood that, if there are terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0037] In addition, if there are terms such as "first", "second", these terms are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In the present application, unless otherwise explicitly specified and limited, if the terms "mounting", "connecting", "connecting", "fixing" and the like appear, these terms should be interpreted broadly. For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0039] In the present application, unless otherwise explicitly specified and limited, if there are similar descriptions such as "first feature on" or "below" the second feature, the meaning can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature "above", "above" and "above" the second feature can be that the first feature is directly above or obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature can be that the first feature is directly below or obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0040] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0041] At corners, internal corners are created, such as the internal corner between adjacent wall formwork sections, or the internal corner between adjacent wall formwork and floor formwork. In related technologies, internal corners are connected using connectors similar to C-grooves and standard formwork, such as... Figure 1 As shown, two or three adjacent templates located at the inside corner are assembled so that concrete can be poured at the inside corner to form a concrete inside corner structure. However, assembling the templates at the inside corner using this method results in a large number of template pieces, leading to low installation efficiency, especially since demolding is difficult, resulting in low overall construction efficiency. In particular, the C-slot connector itself has the following drawbacks: during processing, the C-slot connector is small in size, making welding inconvenient and production complex; the C-slot connector has limited space, making installation inconvenient and resulting in low demolding efficiency for workers; in certain structures, the C-slot connector may not align with the opposite template, requiring auxiliary bolts or back braces for reinforcement.

[0042] See Figures 2-9 , Figures 2-5 A schematic diagram of the structure of the aluminum profile 100 in one embodiment of this application is shown. Figures 6-9 A schematic diagram of the structure of the aluminum formwork 10 in one embodiment of this application is shown. The aluminum formwork 10 provided in this embodiment is applicable to the internal corner structures in various construction scenarios, including but not limited to the internal corners at wall-to-wall connections, wall-to-floor connections, wall-to-wall-to-floor connections, wall-to-beam connections, window openings, and keel-to-floor connections. The corresponding aluminum formwork 10 constitutes a wall-to-wall internal corner connection template 1, a wall-to-floor internal corner connection template 2, a wall-to-wall-to-floor internal corner connection template 32, a wall-to-beam internal corner connection template 4, a window opening internal corner connection template 5, and a keel-to-floor internal corner connection template 6. For example, at the corner between wall formwork 7, i.e., at the internal corner, a wall-to-floor internal corner connection template 2 can be used for connection; at the connection corner between wall formwork 7 and between wall formwork 7 and floor formwork 8, a wall-to-floor internal corner connection template 32 can be used for connection.

[0043] The aluminum profile 100 provided by an embodiment of the present application comprises a main plate 110, a short side plate 120, and an L-shaped side plate 130. The main plate 110 comprises a first edge 111 and a second edge 112 arranged oppositely. The short side plate 120 is vertically arranged at the first edge 111. The L-shaped side plate 130 is vertically arranged at the second edge 112 and comprises a vertical edge 132 and a horizontal edge 131 arranged at an angle, wherein the horizontal edge 131 is parallel to the main plate 110, and the vertical edge 132 is vertically arranged between the horizontal edge 131 and the main plate 110. The main plate 110, the short side plate 120, and the L-shaped side plate 130 are integrally formed, and the height of the short side plate 120 is less than the height of the vertical edge 132.

[0044] The aluminum profile 100 is composed of multiple structures arranged integrally to form an aluminum formwork 10. The aluminum formwork 10 is used to replace the traditional C-slot and its mounting parts. The aluminum formwork 10 is directly arranged at a reentrant corner, thereby reducing the process of combining the C-slot, reducing the required number of formworks, saving time and labor for workers when assembling two adjacent building formworks at the reentrant corner, reducing the installation labor intensity, reducing the installation cost of the construction site while ensuring the construction quality, thereby improving the construction efficiency. Further, the height of the short side plate 120 is less than the height of the vertical edge 132, so that the side where the L-shaped side plate 130 is arranged is arranged at the reentrant corner and used to butt joint with the adjacent formwork, thereby facilitating installation and connection. Meanwhile, the aluminum profile 100 composed of the main plate 110, the short side plate 120, and the L-shaped side plate 130 strengthens the structural design strength of itself, can avoid the application of back lath, and significantly reduces the comprehensive cost.

[0045] In one embodiment, the width L of the main plate 110 is 300-600 mm. Specifically, the main plate 110 is a flat rectangular structure, and the length of the main plate 110 is generally greater than the width of the main plate 110. Preferably, the width L of the main plate 110 can be 300 mm, 350 mm, 400 mm, 450 mm, 500 mm, 550 mm, or 600 mm, and is designed as a standard size. The width L of the main plate 110 can also be designed as a non-standard size according to actual conditions.

[0046] The two edges of the main plate 110 parallel to the length direction thereof are the first edge 111 and the second edge 112, i.e., the two long edges of the main plate 110. The first edge 111 and the second edge 112 are parallel to each other.

[0047] In one embodiment, the short side plate 120 is vertically erected on the first edge 111, and the L-shaped side plate 130 is vertically erected on the second edge 112. The vertical edges 132 of the short side plate 120 and the L-shaped side plate 130 are parallel to each other, and the vertical edges 132 of the short side plate 120 and the L-shaped side plate 130 are perpendicular to the main plate 110. The vertical direction of the short side plate 120 or the vertical edge 132 is also defined as the thickness direction of the main plate 110.

[0048] In other embodiments, the short side plate 120 can be inclinedly erected on the first edge 111, and the L-shaped side plate 130 can be inclinedly erected on the second edge 112. The inclination angle is selected according to actual needs.

[0049] In one embodiment, the thickness C of the main plate 110 is 3.5-5mm. Preferably, the thickness C of the main plate 110 can be 3.5mm, 3.8mm, 4mm, 4.1mm, 4.5mm, 4.7mm, 5mm. The main plate 110 can adopt an aluminum (alloy) plate of this thickness, or can be directly extruded to this thickness, thereby realizing an integrated structure.

[0050] In one embodiment, the difference between the height L2 of the vertical edge 132 and the height L1 of the short side plate 120 is 10-200mm. The difference between the height L2 of the vertical edge 132 and the height L1 of the short side plate 120 is determined according to the size of the internal corner, and the difference within the above range can better configure the corresponding connecting template under the condition of realizing the internal corner connection. Preferably, the difference between the height L2 of the vertical edge 132 and the height L1 of the short side plate 120 is 50mm, 65mm, 80mm, 100mm.

[0051] In one embodiment, the height L2 of the vertical edge 132 is 50-200mm. Further, the height L2 of the vertical edge 132 is 50-200mm, and preferably the height L2 of the vertical edge 132 can be 50mm, 80mm, 100mm, 120mm, 150mm, 180mm, 200mm. Further, the height L1 of the short side plate 120 is 20-150mm, and preferably the height L1 of the short side plate 120 can be 20mm, 35mm, 50mm, 80mm, 100mm, 120mm, 150mm.

[0052] In one embodiment, at least one auxiliary rib 140 is arranged on the main plate 110 along the longitudinal direction of the main plate 110, and the difference between the height L2 of the vertical edge 132 and the height a of the auxiliary rib 140 is greater than 20mm.

[0053] Specifically, the auxiliary ribs 140 are distributed along the longitudinal direction of the main plate 110 and are of the same length as the main plate 110. The auxiliary ribs 140 are used to strengthen the main plate 110. The height of the auxiliary ribs 140 is set relatively low to leave room for the installation of the transverse reinforcing ribs 200. Preferably, the difference between the height of the vertical side 132 and the height 'a' of the auxiliary ribs 140 is 20mm, 30mm, or 40mm.

[0054] In one embodiment, the height a of the auxiliary rib 140 is 10-30 mm, and / or the width b of the auxiliary rib 140 is 4-15 mm. Preferably, the height a of the auxiliary rib 140 is 18 mm, 20 mm, 22 mm, or 25 mm. Preferably, the (maximum) width b of the auxiliary rib 140 is 4 mm, 6 mm, 10 mm, or 12 mm.

[0055] Specifically, the interface of the auxiliary rib 140 is hourglass-shaped, and the width of both the end of the auxiliary rib 140 connected to the main body plate 110 and the end away from the main body plate 110 is greater than the width of the middle part of the auxiliary rib 140. The auxiliary rib 140 is integrally formed with the main body plate 110, the short side plate 120 and the L-shaped side plate 130.

[0056] In one embodiment, when the number of auxiliary ribs 140 is greater than or equal to three, the distance between the auxiliary rib 140 closest to the first edge 111 and the first edge 111 is less than the distance between adjacent auxiliary ribs 140, and / or, the distance between the auxiliary rib 140 closest to the second edge 112 and the second edge 112 is less than the distance between adjacent auxiliary ribs 140.

[0057] The auxiliary ribs 140 near the edges are more densely packed, thereby strengthening the structural strength on both sides of the aluminum formwork 10 for a more stable connection to the external formwork. For example, in Figure 2 , 4 In the embodiment shown, there are three auxiliary ribs 140. The distance between the left auxiliary rib 140 and the first edge 111 is L3, the distance between the right auxiliary rib 140 and the second edge 112 is L4, the distance between the middle auxiliary rib 140 and the left auxiliary rib 140 is L6, and the distance between the middle auxiliary rib 140 and the right auxiliary rib 140 is L5. The value of L3 is 85-105mm, the value of L4 is 95-115mm, and the values ​​of L5 and L6 are 115-150mm.

[0058] In one embodiment, the vertical side 132 and the horizontal side 131 are arranged perpendicularly to form an L-shaped structure, with the horizontal side 131 parallel to the main body plate 110. The horizontal side 131 is used to connect with adjacent standard templates, and the length of the horizontal side 131 is equal to the thickness of the adjacent template. The length of the horizontal side 131 is 20-100mm, preferably 20mm, 35mm, 50mm, 80mm, or 100mm.

[0059] In one embodiment, the horizontal edge 131 and the short side plate 120 are provided with pin holes 150. The pin holes 150 can be arranged at equal intervals, which not only reduces the weight of the horizontal edge 131 and the short side plate 120, but also enables quick installation of the formwork through the cooperation of the pins. Specifically, when the construction of the internal corner is performed, the L-shaped side plate 130 on the aluminum formwork 10 can be first placed against the internal corner, and then the L-shaped side plate 130 on the aluminum formwork 10 and the adjacent building formwork (wall formwork 7 or floor formwork 8) can be spliced and fixed through the cooperation of the pins or other installation members and the pin holes 150, and the short side plate 120 and another adjacent building formwork (wall formwork 7 or floor formwork 8) can be spliced and fixed, as shown in Figure 9 , so as to realize quick construction at the internal corner.

[0060] In one embodiment, at least one reinforcing rib 200 is arranged on the auxiliary rib 140, and the reinforcing rib 200 is a hollow structure. Specifically, the reinforcing rib 200 is arranged along the width direction of the main plate 110, and the reinforcing rib 200 is perpendicular to the short side plate 120 and the vertical edge 132. One side of the reinforcing rib 200 abuts against one end of the auxiliary rib 140 away from the main plate 110, one end of the two ends of the reinforcing rib 200 abuts against the short side plate 120, and the other end of the two ends of the reinforcing rib 200 abuts against the vertical edge 132. The reinforcing rib 200 and the auxiliary rib 140 are connected by welding, and the connection mode includes one or more of spot welding, bubble welding, and vertical welding. Only the reinforcing rib 200 and the auxiliary rib 140 need to be welded, the length of the welding is reduced, and the work efficiency is improved.

[0061] In one embodiment, the reinforcing rib 200 is a rectangular hollow structure, the width M1 of the reinforcing rib 200 is 28-35 mm, the height M2 of the reinforcing rib 200 is 40-45 mm, the reinforcing rib 200 is arranged on the auxiliary rib 140 along the width direction, and the height direction of the reinforcing rib 200 is perpendicular to the main plate 110.

[0062] In one embodiment, the thickness f of the hollow reinforcing rib 200 is 2.2-2.8 mm. The hollow structure is extruded from a pipe material, or directly extruded, or welded or cast.

[0063] In one embodiment, the rectangular reinforcing rib 200 has a rounded design, the outer surface of the reinforcing rib 200 has a rounded radius RX of 3-3.5 mm, and the inner surface of the reinforcing rib 200 has a rounded radius RY of 2-3 mm.

[0064] In one of the embodiments, the reinforcing ribs 200 are provided with at least three, and are divided into a near-ground group, a middle group and a near-floor group. The spacing of the reinforcing ribs 200 in the near-ground group is less than or equal to 350 mm, the spacing of the reinforcing ribs 200 in the middle group is 300-400 mm, and the spacing of the reinforcing ribs 200 in the near-floor group is 400-500 mm. Specifically, the spacing refers to the spacing of the reinforcing ribs 200 from the edge of the main plate 110 or the spacing of the reinforcing ribs 200 from the adjacent reinforcing ribs 200. The reinforcing ribs 200 cooperate with the auxiliary ribs 140 to reinforce the aluminum formwork 10, which can realize the application of eliminating back lath, and the comprehensive cost is significantly reduced.

[0065] The reinforcing ribs 200 near the ground are more densely arranged, and the reinforcing ribs 200 near the floor are more sparsely arranged, so as to strengthen the structural strength of the aluminum formwork 10 to stably support the floor. For example, in the embodiment shown in Figure 6 When the length K of the main plate 110 is less than or equal to 2800 mm, the reinforcing ribs 200 are provided with seven, the distance between the first reinforcing rib 200 and the right edge of the main plate 110 is K1, the spacing of the middle reinforcing ribs 200 from the near-ground end to the near-floor end is K2, K3, K4, K5, K6 and K7 in turn, the distance between the seventh reinforcing rib 200 and the left edge of the main plate 110 is K8, and K1≤300 mm, 300 mm≤K2, K3 and K4≤350 mm, 350 mm≤K5, K6 and K7≤400 mm, and K8≤500 mm.

[0066] The aluminum formwork 10 includes the aluminum profile 100 and the end plate 300 arranged at the end of the aluminum profile 100. In one of the embodiments, the end plate 300 can be flat or L-shaped. When the end plate 300 is flat, as shown in Figure 7 The side of the flat end plate 300 abuts against the main plate 110, and the opposite side is flush with the upper end of the short side plate 120. One end of the flat end plate 300 abuts against the short side plate 120, and the other end of the flat end plate 300 abuts against the vertical edge 132. In this way, the side of the end plate 300 flush with the upper end of the short side plate 120 is arranged in a spaced manner between the horizontal edge 131, forming a gap 301. The aluminum formwork 10 with the structure is convenient to assemble and weld, and has a certain strength. When the end plate 300 is L-shaped, as shown in Figure 8As shown, the L-shaped end plate 300 has a flat side and a high-low distributed side, the flat side abuts against the main plate 110, the low part of the opposite side is flush with the upper end of the short side plate 120, the high part of the opposite side abuts against the lower surface of the horizontal edge 131, one end of the two ends of the L-shaped end plate 300 abuts against the short side plate 120, and the other end of the two ends of the L-shaped end plate 300 abuts against the vertical edge 132. In this way, the L-shaped end plate 300 completely encloses the L-shaped two ends of the aluminum profile 100. The aluminum formwork 10 of this structure has higher support strength and is not easy to be compressed and deformed.
