Description

Technical Field

[0001] This utility model relates to auxiliary fixtures for building construction, specifically a reusable corner construction template. Background Technology

[0002] Inside and outside corners are part of architectural design. Inside corners refer to recessed corners, such as the angle between the ceiling and the surrounding walls; outside corners refer to protruding corners, such as the angle formed by two walls at a corner in a hallway. Significant errors in the placement of inside and outside corners can affect the aesthetics of home decoration and lead to awkward installation and placement of cabinets, furniture, etc., resulting in wasted space.

[0003] In existing technologies, the construction of internal corners typically involves processing the formwork according to the dimensions and angles of the internal corners on the drawings. However, during the on-site installation process, discrepancies in the position and angle of the processed formwork can occur, easily leading to issues such as loose joints, misalignment, and uneven angles at the internal corners. This traditional on-site processing method for internal corner formwork also results in formwork waste, increases carpentry work time, and consequently affects construction progress and quality. Utility Model Content

[0004] This invention designs a reusable internal corner construction template. The entire template is made of steel, has a simple structure, is easy to assemble, and can be reused multiple times, which helps to improve the quality of internal corner construction and speed up the construction progress.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A reusable corner construction template includes an angle adjustment rod, a rotating connecting plate, and a steel template. The length of the angle adjustment rod is adjustable, and both ends of the angle adjustment rod are fixedly connected to the rotating connecting plate. Each rotating connecting plate has a set of steel templates on one side, and the rotating connecting plate is fixedly connected to the steel templates. The included angle between the two sets of steel templates is adjustable. The steel template includes an L-shaped steel plate, a support plate, and a fixing plate. The edge of one flange of each L-shaped steel plate in the two sets of steel templates is hinged by a rotating shaft. The open ends of the L-shaped steel plates in the two sets of steel templates face the same side. Each set of steel templates has a support plate and a fixing plate on the edges of the two flanges of the L-shaped steel plate. The support plate and the fixing plate are respectively clamped on both sides of the flange of the L-shaped steel plate. The support plate and the fixing plate extend beyond the flange edge of the L-shaped steel plate. The support plate, the L-shaped steel plate, and the fixing plate are fixedly connected to form a slot.

[0007] Furthermore, the width of the support plate is greater than the width of the fixing plate, the support plate is located on the outer side of the flange of the L-shaped steel plate, and the fixing plate is located on the inner side of the flange.

[0008] Furthermore, the fixing plate is welded to the flange of the L-shaped steel plate, and the support plate is fixedly connected to the L-shaped steel plate and the fixing plate by bolts.

[0009] Furthermore, the angle adjusting rod includes a sleeve, a first connecting rod, a second connecting rod, and a limiting ring. The sleeve is hollow and has threads on its inner wall. The first connecting rod is a smooth cylindrical rod, and the second connecting rod is a threaded rod. The limiting ring is sleeved and fixed on the first connecting rod. One end of the first connecting rod is connected to the rotating connecting plate, and the other end of the first connecting rod is inserted into the sleeve. The outer diameter of the limiting ring is larger than the outer diameter of the sleeve. The other end of the sleeve is threaded to one end of the second connecting rod, and the other end of the second connecting rod is connected to the rotating connecting plate.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] This embodiment discloses a reusable corner construction template, such as... Figures 1 to 3 As shown, it mainly consists of an angle adjusting rod 1, a rotating connecting plate 2, and a steel template 3. Each end of the angle adjusting rod 1 is connected to a set of rotating connecting plates 2, and the length of the angle adjusting rod 1 is adjustable and can be locked after adjustment. Two sets of steel templates 3 are provided, one set on each side of the rotating connecting plate 2. The steel template 3 has a right-angled L-shaped structure. The rotating connecting plate 2 is fixedly connected to the steel template 3, and the angle adjusting rod 1 is connected to the rotating connecting plate 2. The two sets of steel templates 3 are connected by a hinge. By adjusting the length of the angle adjusting rod 1, the angle formed between the two sets of steel templates 3 can be adjusted. The specific structure of each part will be explained in detail below with reference to the attached drawings.

[0026] In this embodiment, the angle adjusting rod 1 is composed of a hollow cylindrical sleeve 13, a cylindrical first connecting rod 11, a cylindrical second connecting rod 14, and a limiting ring 12. The inner wall of the sleeve 13 is threaded. The first connecting rod 11 is a smooth cylindrical rod, and the second connecting rod 14 is a threaded rod. The outer diameter of the limiting ring 12 is larger than the outer diameter of the sleeve 13. The limiting ring 12 is fitted onto and fixed to the first connecting rod 11. One end of the first connecting rod 11 can be inserted into the sleeve 13 and slide along the inner wall of the sleeve 13. The limiting ring 12 limits the insertion depth of the first connecting rod 11. The other end of the first connecting rod 11 is used to connect to the rotating connecting plate 2. The other end of the sleeve 13 is threadedly connected to the second connecting rod 14. Rotating the sleeve 13 can adjust the insertion depth of the second connecting rod 14 into the sleeve 13. The other end of the second connecting rod 14 is connected to the rotating connecting plate 2 on the other side.

[0027] In this embodiment, the rotating connecting plate 2 consists of a first connecting plate 21, a second connecting plate 22, and a pin 23. The first connecting plate 21 is rectangular, and the second connecting plate 22 has a straight end and an arc-shaped end. A pin 23 is welded to one side of the first connecting plate 21 in a direction perpendicular to the first connecting plate 21. The outer wall of the pin 23 is threaded. A fixing hole is made at one end of the arc-shaped structure of the second connecting plate 22. The straight end of the second connecting plate 22 is welded to the adjacent steel template 3. The fixing hole of the second connecting plate 22 is fitted onto the pin 23. After the angle between the two sets of steel templates 3 is adjusted, a nut is fitted onto the pin 23 to fix and lock the first connecting plate 21 and the second connecting plate 22. The first connecting plate 21 of the rotating connecting plate 2 adjacent to the first connecting rod 11 is welded and fixed to the first connecting rod 11, and the first connecting plate 21 of the rotating connecting plate 2 adjacent to the second connecting rod 14 is welded and fixed to the second connecting rod 14. In this embodiment, the connection end between the second connecting plate 22 and the first connecting plate 21 is designed as an arc-shaped structure, which can better bear the force and thus ensure the durability of the component.

[0028] In this embodiment, the steel formwork 3 is mainly composed of L-shaped steel plates, support plates, and fixing plates, such as... Figures 1 to 3As shown, the steel formwork 3 located on the upper right side mainly consists of a first L-shaped steel plate 31, two first support plates 33, and two first fixing plates 35; the steel formwork 3 located on the lower left side mainly consists of a second L-shaped steel plate 32, two second support plates 34, and two second fixing plates 36. The structures of the two sets of steel formwork 3 are the same. For simplicity, the structure of the steel formwork 3 on the upper right side will be used as an example below. The two flanges of the first L-shaped steel plate 31 form a right angle. The straight section of the second connecting plate 22 in the rotating connecting plate 2 is welded to the outer wall of one of the flanges of the first L-shaped steel plate 31. The first support plate 33, the flange of the first L-shaped steel plate 31, and the first fixing plate 35 have the same length, but the lateral width of the first support plate 33 is greater than the lateral width of the first fixing plate 35. The two first fixing plates 35 are welded to the inner walls of the two flanges of the first L-shaped steel plate 31 near the edge, so that the first fixing plates 35 extend beyond the flanges of the first L-shaped steel plate 31. Holes are drilled at the upper and lower ends of the two flanges of the first L-shaped steel plate 31. A first support plate 33 is fixed to the outer wall of the two flanges near the edge using bolts 39, so that the first support plate 33 extends beyond the flange of the first L-shaped steel plate 31. After this connection, the first support plate 33, the flange side ends, and the first fixing plate 35 form an open slot structure. Both sets of steel templates 3 are assembled according to the structure described above. When the two sets of steel templates 3 are connected to their respective rotating connecting plates 2, their open sides face the same side. A rotating shaft 37 is installed at the edge of one flange of the L-shaped steel plate of one set of steel templates 3, allowing the first L-shaped steel plate 31 and the second L-shaped steel plate 32 of the two sets of steel templates 3 to be hinged via the rotating shaft 37.

[0029] To prevent grout leakage at the connection between the two sets of steel formwork 3 during concrete pouring using the aforementioned construction templates in the construction of the internal corner, this embodiment also includes a folding plate 38 between the unhinged flanges of the first L-shaped steel plate 31 and the second L-shaped steel plate 32. The folding plate 38 connects the flanges of the two L-shaped steel plates. The structure of the folding plate 38 is as follows: Figure 4 As shown, it is mainly composed of multiple metal sheets (8 metal sheets are used as an example in this embodiment) that are hinged together in sequence. Its overall shape is similar to origami. The folding angle between adjacent metal sheets can be changed according to the angle between the two L-shaped steel plates. When the folding plate 38 is fully unfolded, it has a parallelogram structure.

[0030] To facilitate more convenient and accurate adjustment of the included angle between the L-shaped steel plates in the two sets of steel templates 3, this embodiment also includes a scale on the upper surface of the second connecting rod 14 that reflects the angle. This angle scale can be used to determine the included angle between the two L-shaped steel plates. For example, an isosceles triangle can be drawn on a drawing in CAD at the position corresponding to the included angle. The lengths of the two equal sides of the isosceles triangle are the distances from the second connecting plate 22 to the intersection of the two L-shaped steel plates. By drawing the triangle, the length of the third side of the isosceles triangle can be determined, and this length is the length shown by the scale on the second connecting rod 14.

[0031] When using the construction template designed above to complete the construction of the inside corner, first loosen the nut on the pin 23 so that the second connecting plate 22 and the first connecting plate 21 can rotate relative to each other. Then, according to the dimensions and angles of the inside corner design on the drawing, adjust the depth of the second connecting rod 14 inserted into the sleeve 13 by rotating the sleeve 13. At the same time, observe the scale indication on the second connecting rod 14. When the required angle scale is reached, stop rotating the sleeve 13, indicating that the inside corner angle formed between the first L-shaped steel plate 31 and the second L-shaped steel plate 32 has been adjusted to the correct position. At this time, tighten the nut to lock the first connecting plate 21 and the second connecting plate 22 to prevent relative rotation. Then, place the adjusted construction template flat and insert the bottom mold into the slots on both sides of the L-shaped steel plate of the two sets of steel templates 3. Next, brush the release agent on each plate wall on the open side of the L-shaped steel plate. Finally, pour concrete at the open ends of the two sets of steel templates 3. After the concrete has cured, the construction template can be removed.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
