Description

Technical Field

[0001] This invention relates to auxiliary fixtures for building construction, specifically to a corner construction template and a corner construction method. 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. Summary of the Invention

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

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A corner construction template includes an angle adjusting rod, two sets of rotating connecting plates, and two sets of steel templates. The angle adjusting rod includes a sleeve with internal threads, a smooth cylindrical first connecting rod, a second connecting rod, and a limiting ring. The second connecting rod is a threaded rod, and the limiting ring is sleeved and fixed on the first connecting rod. One end of the first connecting rod is inserted into the sleeve, and the limiting ring is located outside the sleeve. The second connecting rod is threadedly connected to the sleeve. The rotating connecting plate includes a first connecting plate, a second connecting plate, and a pin with threads on its outer wall. The pin is vertically fixed to the first connecting plate, and a fixing hole is opened at one end of the second connecting plate. The fixing hole of the second connecting plate is sleeved on the pin, and a nut is installed to fix the first connecting plate and the second connecting plate. A set of rotating connecting plates is respectively provided at both ends of the angle adjusting rod. The other end of the first connecting rod is fixedly connected to the first connecting plate of the rotating connecting plate on the same side, and the other end of the second connecting rod is fixedly connected to the first connecting plate of the rotating connecting plate on the same side.

[0007] Each set of steel formwork includes one L-shaped steel plate, two support plates, and two fixing plates. The open ends of the L-shaped steel plates in both sets of steel formwork face the same side, and the edges of one flange of each of the two L-shaped steel plates are hinged together by a rotating shaft. The two flanges of the two L-shaped steel plates in the two sets of steel formwork are connected by a folding plate. Each set of steel formwork has a support plate and a fixing plate on the edge of each flange of the L-shaped steel plate. The support plate and the fixing plate are respectively clamped and fixed 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, L-shaped steel plate, and fixing plate are fixedly connected to form a slot. The second connecting plate of the rotating connecting plate is fixed on the flange of the L-shaped steel plate. The surface of the second connecting rod is engraved with a scale for judging the included angle between the flanges of the hinged ends of the two L-shaped steel plates.

[0008] 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.

[0009] Furthermore, the fixing plate is welded to the inner wall of the flange of the L-shaped steel plate, and the support plate is fixed to the outer wall of the flange of the L-shaped steel plate by bolts.

[0010] Furthermore, the first connecting plate is a rectangular connecting plate, and the end of the second connecting plate connected to the first connecting plate is an arc-shaped structure.

[0011] Furthermore, the folding plate is formed by connecting multiple metal sheets in sequence by hinge, and when fully unfolded, the folding plate presents a parallelogram structure.

[0012] This invention also discloses a method for constructing inside corners using the aforementioned inside corner construction template, comprising the following steps:

[0013] Step 1): Assemble the internal corner construction template;

[0014] Step 2): According to the design angle of the inside corner on the drawing, loosen the nuts between the first and second connecting plates on the two sets of rotating connecting plates so that the first and second connecting plates can rotate relative to each other. Then rotate the sleeve on the angle adjustment rod to adjust the depth of the second connecting rod inserted into the sleeve and observe the scale on the second connecting rod until the inside corner angle on the drawing is reached. Then stop rotating the sleeve and tighten the nut.

[0015] Step 3): Lay the inside corner construction template flat, insert the bottom mold into the slots on the corresponding sides of the two sets of steel templates, and fix the bottom mold;

[0016] Step 4): Apply release agent to each panel wall on the open side of the two sets of steel formwork, and then pour concrete into the open end of each set of steel formwork.

[0017] Step 5): After the concrete has cured, remove the construction formwork for the inside corner.

[0018] This invention uses steel to design and manufacture special templates for inside corner construction, eliminating the need for on-site wood processing and thus avoiding wood waste. The entire set of inside corner construction templates is simple, durable, easy to assemble, and can be reused multiple times. On-site, the angle between the two sets of steel templates can be flexibly adjusted according to the design dimensions and angle requirements of the inside corner on the drawings. This reduces errors in the angle dimensions of the inside corner, minimizes the occurrence of loose joints, grout leakage, and misalignment during inside corner construction, and helps simplify the inside corner construction process, improve construction progress, and enhance construction quality.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] This embodiment discloses a reusable corner construction template, such as... Figures 1 to 3As 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.

[0029] 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.

[0030] 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.

[0031] 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 3 As 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.

[0032] 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.

[0033] 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.

[0034] This embodiment also discloses a method for constructing inside corners using the aforementioned inside corner construction template, including the following steps:

[0035] Step 1): Assemble the internal corner construction template according to the structure given above.

[0036] Step 2): According to the design angle of the inside corner on the drawing, adjust the included angle formed by the corresponding L-shaped steel plate flanges between the two sets of steel templates 3 so that the included angle is the same as required by the drawing. The adjustment process is as follows: First, loosen the nuts between the first connecting plate 21 and the second connecting plate 22 on the two sets of rotating connecting plates 2 so that the first connecting plate 21 and the second connecting plate 22 can rotate relative to each other; then rotate the sleeve 13 on the angle adjusting rod 1 to adjust the depth of the second connecting rod 14 inserted into the sleeve 13, and observe the scale on the second connecting rod 14 until the inside corner angle on the drawing is reached, then stop rotating the sleeve 13 and tighten the nut to fix the relative position of the first connecting plate 21 and the second connecting plate 22.

[0037] Step 3): After completing Step 2), lay the inside corner construction template flat, insert the bottom mold into the slots on the corresponding sides of the two sets of steel templates 3, and fix the bottom mold.

[0038] Step 4): After completing Step 3), apply release agent to each panel wall on the open side of the two sets of steel formwork 3, and then pour concrete into the open end of each set of steel formwork 3.

[0039] Step 5): After the concrete has cured, remove the construction formwork for the inside corner.
