Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy formwork construction technology, specifically to an aluminum alloy formwork for external corners of walls. Background Technology

[0002] An external corner is a term used in the construction industry, referring to a protruding corner on a wall, such as the four protruding corners of a building's exterior or the angle between door / window openings and the wall. Aluminum alloy formwork offers advantages over wooden or steel formwork, including lighter weight, higher strength, shorter construction period, fewer construction workers required, and better concrete appearance.

[0003] Utility model CN219509165U discloses an aluminum alloy template for wall corners, comprising a corner template with a first mounting plate and a second mounting plate fixedly installed on it. A first locking block and a second locking block are slidably mounted on the first and second mounting plates, respectively. A spring is fixedly installed on the first locking block, and a fixing ring is fixedly installed on the other end of the spring. A bearing is embedded in the fixing ring, and a rotating rod is fixedly installed on the bearing. Fixing blocks are evenly and uniformly fixedly installed on the rotating rod. The second locking block has a second locking block and a locking groove. This utility model allows the two locking blocks to be tightly connected and engaged by accommodating the fixing blocks inside the locking groove. The engagement method is simple and easy to use, and installation and disassembly are quick and easy, eliminating the need for manually tightening multiple sets of screws, resulting in high efficiency. Furthermore, the integrated design prevents the loss of parts and avoids unnecessary economic losses.

[0004] However, the above-mentioned existing technology still has shortcomings in use: when two external corner templates forming a 90° angle are connected using the above-mentioned existing technology, gaps are prone to appear. Specifically, the slider inside the groove is in a free sliding state, that is, it does not have a locking function, which makes the two external corner templates not have a tight connection function, making gaps easy to appear, and thus easily causing material leakage after concrete is poured.

[0005] Therefore, this utility model provides an aluminum alloy template for external corners of walls. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an aluminum alloy template for the external corner of a wall to solve the problems mentioned in the background art. This utility model has the function of tightly locking the left and right external corner plates spliced ​​at 90 degrees, so that there will be no problem of material leakage during pouring. Moreover, the assembly and disassembly of the left and right external corner plates are more convenient and quick.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an aluminum alloy template for wall corners, comprising a left corner plate and a right corner plate, wherein the outer sides of the left and right corner plates are rotatably connected to two vertically distributed arms with the rotatable connection located in the middle of the arms, and both ends of the arms are provided with opposingly distributed limiting blocks and insertion holes, the limiting blocks and insertion holes being inserted into each other, and the outer sides of the left and right corner plates are each provided with a limiting block located between the two arms that slides left and right.

[0008] Furthermore, both the left and right external corner plates are provided with vertically distributed rotating connectors on their outer sides, and the rotating connectors are detachably connected to the arm.

[0009] Furthermore, the rotating connector includes a threaded sleeve and a T-shaped rod. The outer sides of the left and right external corner plates are fixedly connected to one end of the threaded sleeve. A limiting sleeve is fixedly and penetratedly connected to the arm. The limiting sleeve and the T-shaped rod are rotatably and detachably connected. One end of the T-shaped rod is fixedly connected to a screw that is screwed into the threaded sleeve.

[0010] Furthermore, the limiting sleeve and the T-shaped rod are fitted together.

[0011] Furthermore, two stop blocks, one near the two ends, are fixedly connected to both sides of the arm, and the upper and lower ends of the limiting block are provided with limiting grooves that magnetically engage with the stop blocks.

[0012] Furthermore, guide plates are fixedly connected to the outer sides of both the left and right external corner plates. A sliding groove is provided on the front side of the guide plate, and a slider that slides in cooperation with the sliding groove is fixedly connected to one side of the limiting block.

[0013] Furthermore, the limiting insert has a multi-faceted pyramidal structure with the small end facing outwards.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, an arm, a limiting block, a limiting insert block, and an insertion hole are provided. Two arms are rotatably connected to the outside of the left and right corner plates. The limiting block is slidably connected between the two arms. By rotating the arms on the left and right corner plates, the limiting insert block and the insertion hole are inserted. At this time, the left and right corner plates are in a 90-degree locked state. Compared with the prior art, this arrangement has the advantage of improving the tight connection strength between the left and right corner plates.

[0016] 2. In this utility model, a rotating connector is provided, and the left and right external corner plates are detachably connected to the arm through the rotating connector. This design facilitates the replacement of the arm, meaning that the arm can be quickly replaced when it is bent or deformed. This design improves the service life of this template.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: an aluminum alloy template for the external corner of a wall, including a left external corner plate 1 and a right external corner plate 2. Here, the left external corner plate 1 and the right external corner plate 2 refer to the left and right templates located at the external corner position during use. The outer sides of the left external corner plate 1 and the right external corner plate 2 are rotatably connected to two vertically distributed arms 3, and the rotatable connection is located in the middle of the arms 3. Specifically, the rotatable connection positions of the two arms 3 are vertically distributed, and the rotation axis of the arms 3 is perpendicular to the left external corner plate 1 and the right external corner plate 2 connected to them. In this embodiment, the arms 3 are parallel to the left external corner plate 1 and the right external corner plate 2 connected to them.

[0023] Specifically, both the left external corner plate 1 and the right external corner plate 2 are provided with rotating connecting parts 7 distributed vertically on their outer sides. The rotating connecting parts 7 and the arm 3 are detachably connected. This detachable connection structure makes the arm 3 easy to replace and maintain, greatly extending the service life of this template.

[0024] The arm 3 has two ends with opposing limiting blocks 4 and insertion holes 5. The limiting blocks 4 and insertion holes 5 are inserted into each other. In specific implementation, it is preferred that the limiting blocks 4 have a multi-faceted pyramidal structure with the small end facing outward. After the limiting blocks 4 are inserted into the insertion holes 5, the corresponding arm 3 cannot rotate when it is in a vertical state. The cone-shaped structure of the limiting blocks 4 ensures that the limiting blocks 4 can enter the insertion holes 5 in an arc trajectory when the arm 3 rotates.

[0025] Furthermore, both the left and right external corner plates 1 and 2 have slidable limiting blocks 6 located between the two arm rods 3 on their outer sides. The limiting blocks 6 restrict the rotation of the two adjacent arm rods 3 and have the function of applying rotational thrust to the two adjacent arm rods 3.

[0026] Specifically, the two sides of the arm 3 are fixedly connected to a stop block 33 and a stop block 34 near the two ends. It should be noted that the lengths of the stop block 33 and the stop block 34 are different. The upper and lower ends of the limiting block 6 are provided with limiting grooves 61 that magnetically engage with the stop blocks 33 and the stop blocks 34. The magnetic engagement is specifically achieved by embedding magnets in the limiting grooves 61. The stop blocks 33 and the stop blocks 34 are made of materials with specific magnetic properties, so as to facilitate mutual attraction and limitation with the limiting grooves 61. When the limiting block 6 moves, it will apply a squeezing and pushing force to the two adjacent arms 3 through the stop blocks 33 or the stop blocks 34.

[0027] Among them, the outer sides of the left corner plate 1 and the right corner plate 2 are fixedly connected to the guide plate 8. The front side of the guide plate 8 is provided with a sliding groove 81. The side of the limiting block 6 is fixedly connected to a slider 62 that slides with the sliding groove 81. The slider 62 can be a T-shaped structure that is adapted to the sliding groove 81.

[0028] In this embodiment, the rotating connector 7 includes a threaded sleeve 71 and a T-shaped rod 72. The T-shaped rod 72 can be a pin structure with an external hexagonal head at one end. The outer sides of the left and right external angle plates 1 and 2 are fixedly connected to one end of the threaded sleeve 71. A limiting sleeve 31 is fixedly and penetrates the arm 3. The limiting sleeve 31 and the T-shaped rod 72 are rotatably and detachably connected. In specific implementation, it is preferred that the limiting sleeve 31 and the T-shaped rod 72 have a transition fit. This setting makes the rotation of the arm 3 more precise and has a certain rotational resistance. Among them, one end of the T-shaped rod 72 is fixedly connected to a screw 721 that is screwed into the threaded sleeve 71. When the screw 721 is tightened, the limiting sleeve 31 is in a state of no axial movement.

[0029] Working principle: In use, install the left corner plate 1 and right corner plate 2 as described in the patent literature mentioned in the background art, forming a right angle structure. Then, manually push the limiting block 6 on the right corner plate 2, causing the limiting block 6 to pass through the second stop 34, making the two adjacent arms 3 parallel. Then, push the limiting block 6 on the left corner plate 1, causing the limiting block 6 to pass through the adjacent first stop 33, making the two adjacent arms 3 parallel and located outside the two arms 3 on the right corner plate 2. At the same time, the limiting insert 4 will insert into the corresponding insertion hole 5. At this time, the adjacent arms 3 are in a tight connection state, and the left corner plate 1 and right corner plate 2 are in a locked state. When disassembly is required, simply use a tool to tap one of the limiting blocks 6 in the opposite direction.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
