Description

Technical Field

[0001] This utility model relates to the field of roof construction, specifically a rapid construction device for the R-angle of a roof's internal corner. Background Technology

[0002] Roofing is a crucial component of building construction, significantly impacting the overall quality of the building. Roofing structures include parapet walls, equipment foundations, flues, and equipment rooms, resulting in numerous internal corners. To prevent leaks in these corners, rounded (R-corner) designs are often used. Traditionally, control lines are first laid out on the parapet wall and roof, then PVC strips are manually applied to control height and width. Finally, workers apply plaster to the inside of the PVC strips to create the R-corner. This process often results in poor R-corner quality and inconsistent thickness in the middle. Another method involves using a special mold to apply a full coat of plaster after the R-corner is applied for aesthetic purposes. This method requires highly skilled workers who need to control the quality and speed of the mold application, making it difficult to accurately control the quality and speed of the R-corner application. Utility Model Content

[0003] The purpose of this utility model is to provide a rapid construction device for the R-corner of the roof's internal corner. It can solve the technical problem that the construction quality and speed of the R-corner at the existing internal corner are not easy to accurately control, improve the flatness of the R-corner construction, and make the construction quality less affected by the worker's experience, thus greatly improving the quality and efficiency of the R-corner construction.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A rapid construction device for the R-angle of a roof's internal corner includes a construction frame installed at the internal corner. The horizontal portion of the internal corner is provided with a stop bar. The construction frame includes an upper horizontal bar and a lower horizontal bar. The upper horizontal bar contacts the vertical portion of the internal corner, and the lower horizontal bar contacts the horizontal portion of the internal corner. Multiple arc-shaped bars are provided between the upper and lower horizontal bars. Multiple limiting blocks are provided on the lower horizontal bar, and multiple limiting grooves are provided on the stop bar to cooperate with the limiting blocks.

[0006] Furthermore, reinforcing bars are provided between the plurality of the arc-shaped bars.

[0007] Furthermore, the limiting groove is disposed on the top of the stop bar, and the limiting block is movably inserted into the limiting groove.

[0008] Furthermore, the end of the limiting block is provided with a protrusion, the width of the protrusion is greater than that of the limiting block, and the limiting groove is provided with a groove that cooperates with the protrusion.

[0009] Furthermore, the protrusion is provided with a through hole, and the groove is provided with a limiting post, which passes through the through hole and is movably inserted into it.

[0010] Furthermore, the height of the limiting post is greater than the depth of the perforation.

[0011] Furthermore, a handle is provided between the upper crossbar and the lower crossbar.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The structure of this utility model sets up a construction frame at the inside corner of the roof. The construction frame includes an upper horizontal bar and a lower horizontal bar. The upper horizontal bar contacts the vertical part of the inside corner, and the lower horizontal bar contacts the horizontal part of the inside corner. Multiple arc-shaped bars are provided between the upper and lower horizontal bars. During construction, the construction frame is placed at the inside corner, and plaster is applied inside the construction frame. Then, a scraper is used to scrape off the excess plaster along the arc-shaped bars between the upper and lower horizontal bars, thereby forming a smooth arc-shaped R-corner surface. Afterward, the construction frame is removed and moved to an adjacent position. The above operation is repeated to complete the R-corner construction at the entire inside corner. Afterward, the concave positions of the arc-shaped bars are filled to ensure the integrity of the R-corner construction. The entire construction process uses arc-shaped bars to limit and define the arc-shaped surface of the R-corner, ensuring the flatness of the arc-shaped surface of the R-corner. The construction is not affected by the worker's experience, which greatly improves the quality and efficiency of R-corner construction.

[0014] 2. A stop bar is provided in the horizontal part of the inside corner, and multiple limiting blocks are provided on the lower horizontal bar. The stop bar is provided with multiple limiting grooves that cooperate with the limiting blocks during construction. With this structure, when the construction frame is placed in the inside corner, the limiting blocks enter the limiting grooves, thereby fixing the placement position of the construction frame. This allows the construction frame to accurately define the boundary of the R-corner construction. When the surface of the R-corner is scraped and shaped using a scraper, the construction frame will not move, ensuring the flatness of the R-corner arc surface and further ensuring the quality of the R-corner construction.

[0023] Reference Figure 1 and Figure 2This utility model describes a rapid construction device for the R-angle of a roof's internal corner. The main structure includes a construction frame positioned at the internal corner 1, located at the corner of the roof and parapet wall. During construction, the construction frame is placed at the corner. A stop strip 2 is provided on the horizontal portion of the internal corner 1, fixed to one side of the roof surface by adhesive or other means. The construction frame includes a parallel upper horizontal bar 3 and a lower horizontal bar 4, both extending along the length of the internal corner 1 and made of metal. The upper horizontal bar 3 contacts the vertical portion of the internal corner 1. The lower horizontal bar 4 contacts the transverse portion of the inside corner 1, making the construction frame more stable when placed at the inside corner 1. Multiple arc-shaped bars 5 are provided between the upper horizontal bar 3 and the lower horizontal bar 4. Preferably, these arc-shaped bars 5 are fixed at both ends and the middle by welding. The curvature of the arc-shaped bars 5 is customized according to the surface curvature of the R-angle. With this structure, during construction, the construction frame is placed at the inside corner 1, so that the upper horizontal bar 3 contacts the vertical parapet wall side of the inside corner 1, and the lower horizontal bar 4 contacts the transverse roof side of the inside corner 1. Then, plaster is poured into the interior of the construction frame and filled, and then a scraper is used... The excess plaster is scraped off along the direction of the arc-shaped rod 5, so that the plaster surface forms an arc-shaped surface consistent with the bending direction of the arc-shaped rod 5. Afterwards, the construction frame is removed and moved to an adjacent location, and the above construction is repeated until the entire inside corner 1 is completed. Then, the recessed areas of the arc-shaped rod 5 on the inside corner are filled to ensure the integrity of the inside corner surface. This structure makes the surface of the inside corner construction smoother, the construction speed faster, and the construction quality is not affected by the worker's experience, greatly improving the quality and efficiency of the inside corner 1 inside corner construction. The lower crossbar 4 is welded... The baffle 2 is fixed with multiple limiting blocks 6 in one piece or by a joint. The baffle 2 is provided with multiple limiting grooves 7 that cooperate with the limiting blocks 6. With this structure, the baffle 2 is pasted and fixed to the designated position on the roof in advance by laying out lines. When the construction frame is placed at the inside corner 1, the multiple limiting blocks 6 on the lower horizontal bar 4 enter the limiting grooves 7 of the baffle 2 at the same time, thereby accurately limiting the position of the construction frame. This ensures that the construction frame will not move when the scraper is used to scrape off the excess plaster along the direction of the arc rod 5, so that the surface of the formed R corner is flatter and further ensures the quality of the R corner construction.

[0024] Preferably, a reinforcing rod 8 is fixed between the multiple arc-shaped rods 5 by welding or integral molding. The reinforcing rod 8 connects and fixes the multiple arc-shaped rods 5, making it less likely for the middle part of the arc-shaped rods 5 to bend, thereby more accurately defining the curvature of the R-angle surface and further ensuring the quality of R-angle construction.

[0025] Preferably, the limiting groove 7 is located on the top of the baffle 2, and the limiting block 6 is movably inserted into the limiting groove 7. The limiting groove 7 is recessed downward from the top of the baffle 2, so that when the construction frame is placed at the inside corner 1, the limiting block 6 is movably inserted into the limiting groove 7 from above, making the cooperation between the limiting block 6 and the limiting groove 7 more convenient and further improving the convenience of the device construction.

[0026] Preferred, refer to Figure 4 and Figure 5 The end of the limiting block 6 is fixed with a protrusion 9 by welding or integral molding. The width of the protrusion 9 is greater than that of the limiting block 6. The limiting groove 7 is connected with a groove 10 that cooperates with the protrusion 9. This structure allows the protrusion 9 to be inserted into the groove 10 after the limiting block 6 is movably inserted into the limiting groove 7. Since there is a width difference between the protrusion 9 and the limiting block 6, a limiting step is formed at the connection position, which makes it less likely for the limiting block 6 to be misaligned relative to the limiting groove 7, and further improves the limiting and fixing effect on the construction frame.

[0027] Preferably, the protrusion 9 is provided with a through hole 11, and a limiting post 12 is fixed in the groove 10 by welding or integral molding. The limiting post 12 passes through the through hole 11 and is movably inserted into it. This structure makes the through hole 11 on the protrusion 9 fit around the outside of the limiting post 12 when the protrusion 9 and the groove 10 are movably inserted, thereby making the fit between the protrusion 9 and the groove 10 more secure and further improving the robustness of the limiting structure.

[0028] Preferred, refer to Figure 3 The height of the limiting post 12 is greater than the depth of the through hole 11. This structure allows the top of the limiting post 12 to be higher than the top of the protrusion 9 after the protrusion 9 is inserted into the groove 10, thereby further restricting the protrusion 9. Even if the limiting block 6 is lifted out of the limiting groove 7 due to external force, the limiting post 12 can still restrict the position of the limiting block 6 to prevent it from being misaligned, thus further ensuring the stability of the construction frame during construction.

[0029] Preferably, a handle 13 is fixed between the upper crossbar 3 and the lower crossbar 4 by welding or bolts. Preferably, the longitudinal section of the handle 13 is L-shaped, and the two ends of the L-shape are fixedly connected to the upper crossbar 3 and the lower crossbar 4 by welding or integral molding, which makes it convenient for construction personnel to hold the handle 13 to place and retrieve the construction frame, further improving the convenience of using the device.

[0030] Working Principle: This utility model's structure features a construction frame at the inside corner 1 of the roof. The construction frame includes an upper horizontal bar 3 and a lower horizontal bar 4. The upper horizontal bar 3 contacts the vertical portion of the inside corner 1, and the lower horizontal bar 4 contacts the horizontal portion of the inside corner 1. Multiple arc-shaped bars 5 are positioned between the upper horizontal bar 3 and the lower horizontal bar 4. During construction, the construction frame is placed at the inside corner 1, and plaster is applied inside the frame. Excess plaster is then scraped away using a scraper along the arc-shaped bars 5 between the upper horizontal bar 3 and the lower horizontal bar 4, creating a smooth, rounded corner surface. The construction frame is then removed and moved to an adjacent location, and the above operation is repeated to complete the rounded corner construction at the entire inside corner 1. Finally, any recesses in the arc-shaped bars 5 are filled to ensure the integrity of the rounded corner construction. The construction process utilizes an arc-shaped rod 5 to restrict and define the arc-shaped surface of the R-corner, ensuring the flatness of the arc-shaped surface of the R-corner. The construction is not affected by the worker's experience, greatly improving the quality and efficiency of R-corner construction. A stop strip 2 is provided in the horizontal part of the inside corner 1, and multiple limiting blocks 6 are provided on the lower horizontal bar 4. Multiple limiting grooves 7 are provided on the stop strip 2 to cooperate with the limiting blocks 6 in construction. With this structure, when the construction frame is placed at the inside corner 1, the limiting blocks 6 enter the limiting grooves 7, thereby fixing the placement position of the construction frame. This allows the construction frame to accurately define the boundary of the R-corner construction. When the surface of the R-corner is scraped and shaped using a scraper, the construction frame will not move, ensuring the flatness of the formed arc-shaped surface of the R-corner and further ensuring the quality of the R-corner construction.
