Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a one-time molding and crack-preventing construction method for roof panels and upper-mounted structural walls. Background Technology

[0002] Currently, the construction of new roofs typically involves the construction of the upper structural walls and roof panels, which are then integrated into a cohesive whole. The roof panels are located at the bottom of the roof, connecting the roof and the lower end walls of the roof structure and transmitting pressure. The space between the upper structural walls and the roof panels forms the machine room layer, which is used to house electrical equipment and other devices.

[0003] In the construction of new roof concrete structures, the top roof slab is usually constructed first, followed by the upper structural walls. In order to ensure that the two are effectively integrated and to ensure the quality of the construction, the traditional construction method usually uses machinery to roughen the contact surfaces of the two into an uneven, rough surface before pouring the concrete. This improves the interlocking force between the walls and strengthens the connection between them.

[0004] Regarding the aforementioned technologies, the roughening process of the machine relies heavily on the operator's skill level, which can easily lead to unstable wall bonding due to inadequate roughening, resulting in cracks and leaks at the wall joints. Therefore, there is an urgent need for a construction method that can reduce the probability of wall cracking. Utility Model Content

[0005] To improve the construction stability between the roof structure wall and the roof panel, this application provides a one-time molding construction method to prevent cracking of the roof panel and the roof structure wall.

[0006] This application provides a one-time molding and crack-resistant construction method for roof panels and upper-mounted structural walls, employing the following technical solution: A method for preventing cracking in a roof panel and upper-mounted structural wall through one-time molding includes a top slab located at the upper end of the roof. The top slab is equipped with construction templates, including template one, template two, template three, and template four. Template one and template two are vertically opposite each other, with the lower end of template two higher than the lower end of template four. Template three is located at the lower end of template two and is parallel and aligned with it. Template four is located at the upper end of template three and is perpendicular to it, extending away from template one. During concrete pouring, the concrete flows through the space between template one and template two, and through the gap between template two and template three to the top of template four. Reinforcing cages for fixing template one and template two are provided on the opposite sides of template one and template two. Several water-stop bolts are connected to the reinforcing cages, passing through the two reinforcing cages sequentially in a transverse direction. A shielding component is provided on the opposite side of template two, extending away from template one, for shielding and reinforcing the concrete.

[0007] By adopting the above technical solution, the top slab supports templates three and four, and template four supports template two. Template two supports template one through several water-stop bolts. The water-stop bolts fix and support templates one and two by clamping two steel cages. The steel cages help improve the structural rigidity of templates one and two. When pouring concrete, the space between templates one and two, the space between templates one and three, and the space at the upper end of template four are filled. The shielding component blocks and intercepts the concrete above template four, so that the roof panel and the roof wall are cast as a whole. The shielding component reinforces the formed concrete, reduces the probability of cracking between the roof panel and the upper structural wall, and helps improve the stability of the wall construction.

[0008] Optionally, the reinforcing cage includes several support columns and several support rods. The support columns are arranged parallel to the first template, and the support rods are located between the support columns and the first template and are connected to both the support rods and the first template. The reinforcing cage structure on the second template is the same as the reinforcing cage structure on the first template. The water-stop bolts pass through the two support columns in sequence and abut against the outer wall of the support columns.

[0009] By adopting the above technical solution, the support rod connects the support column and the first template, and the water-stop screw clamps the support column, so that the support column clamps the first template and the second template through the support rod. At the same time, the cooperation of several support columns and support rods improves the overall rigidity of the structure.

[0010] Optionally, the support columns have several vertically formed grooves on their adjacent sides, and the support rods are inserted into the grooves and fixedly connected to the inner wall of the grooves.

[0011] By adopting the above technical solution, the support column fixes and supports the support rod through the groove. By increasing the contact area between the support column and the support rod, the connection stability between the support column and the support rod is improved, thereby reducing the probability of cracking at the end face of the support column.

[0012] Optionally, a number of reinforcing rods are provided between template one and template two, with adjacent reinforcing rods arranged crosswise, and the two ends of two reinforcing rods along the length direction are respectively connected to template one and template two.

[0013] By adopting the above technical solution, the reinforcing rod connects template one and template two, further strengthening the connection stability between template one and template two, thereby increasing the clamping force of template one and template two on the concrete, further reinforcing the formed concrete, and helping to reduce the probability of concrete cracking.

[0014] Optionally, a rotating rod is provided between the two reinforcing rods. The rotating rod passes through the two reinforcing rods in sequence and is rotatably connected to both reinforcing rods in a vertical direction. The rotating rod is provided with a fixing component 1 for fixing the angle of the reinforcing rod. The two sides of the reinforcing rod along the length direction are respectively slidably connected to template 1 and template 2 in a vertical direction. The ends of the reinforcing rods are provided with fixing components 2.

[0015] By adopting the above technical solution, template one and template two support the reinforcing plate, and the rotating rod is limited when the two reinforcing plates rotate relative to each other. When the water-stop screw adjusts the distance between template one and template two, the reinforcing rod rotates to change the angle to adapt to the distance between template one and template two, thereby adapting to walls with different width requirements. Fixing component one fixes the angle between the two reinforcing rods, and fixing component two fixes the reinforcing rod to the wall, which helps to improve the applicability of the structure.

[0016] Optionally, the fixing component includes two fixing plates and two nuts. The fixing plates are provided with limiting grooves that are adapted to the reinforcing rod. The two nuts are threaded to both ends of the rotating rod that pass through the reinforcing rod. The nuts abut against the side of the fixing plate away from the reinforcing rod, which helps to improve the installation stability of the reinforcing rod.

[0017] By adopting the above technical solution, after the angle between the reinforcing rods is determined, the operator rotates the nuts so that both nuts abut against the adjacent fixing plates, and further fixes the angle between the reinforcing rods by the fixing plates. The fixing plates increase the contact area with the reinforcing rods through the limiting groove, thereby improving the support stability of the fixing plates for the reinforcing rods, thereby improving the connection stability between the reinforcing rods, and ultimately improving the structural support force on the concrete.

[0018] Optionally, the second fastener includes an abutment plate and a bolt. The abutment plate is located at the end of the reinforcing rod and is hinged to the end of the reinforcing rod. The bolt passes through the abutment plate and is inserted into template one or template two, and is threadedly connected to template one and template two. The bolt head abuts against template one or template two.

[0019] By adopting the above technical solution, bolts are used to connect and fix the abutment plate and template one or template two, so that the reinforcing rod and template one or template two are relatively fixed, which helps to improve the connection stability between the reinforcing rod and template one and template two, and thus improves the support stability of the reinforcing rod on the concrete.

[0020] Optionally, the upper end of the template is provided with several bent plates along the lateral direction.

[0021] By adopting the above technical solution, the fourth template further supports and reinforces the concrete with a bending plate. When cracks appear in the concrete and cause leakage, the bending plate reduces the probability of water penetrating the wall by extending the water penetration path.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The top slab supports templates three and four, and template two is supported by template four. Template two is supported by several water-stop bolts. The water-stop bolts fix and support templates one and two by clamping two steel cages. The steel cages help improve the structural rigidity of templates one and two. When the concrete is poured, the space between templates one and two, the space between templates one and three, and the space at the top of template four are filled. The shielding component shields and intercepts the concrete above template four, so that the roof panel and the roof wall are cast as a whole. The shielding component reinforces the formed concrete, reduces the probability of cracking between the roof panel and the upper structure wall, and helps to improve the stability of the wall construction. 2. The support rod connects the support column and the first template. The water-stop bolt clamps the support column, so that the support column clamps the first template and the second template through the support rod. At the same time, several support columns and support rods work together to improve the overall rigidity of the structure. 3. The support column fixes and supports the support rod through the groove. By increasing the contact area between the support column and the support rod, the connection stability between the support column and the support rod is improved, thereby reducing the probability of cracking at the end face of the support column.

[0029] The present application will be further described in detail below with reference to all the accompanying drawings.

[0030] This application discloses a method for preventing cracking by one-time molding of roof panels and upper-mounted structural walls. Example

[0031] Reference Figure 1 A method for preventing cracking in a roof panel and upper-mounted structural wall through one-time molding includes a roof panel 1, which is located at the upper end of the roof and covers the roof. A construction template 2 is installed on the upper end of the roof panel 1. The construction template 2 includes template 1 21, template 22, template 3 23 and template 4 24. Templates 1 21, 22 and 3 23 are all vertically set. Templates 1 21 and 22 are opposite to each other. Template 3 23 is installed on one side of the roof panel 1 along the width direction and is aligned with the lower end of template 2 22. Template 4 24 is horizontally set and installed on the upper end of template 3 23. Template 4 24 extends away from template 1. A steel pipe is installed between template 4 24 and the roof panel 1. The roof panel 1 supports and fixes template 4 24 through the steel pipe, and also supports template 3 23.

[0032] Both template 1 21 and template 2 22 are equipped with steel cages 3 on opposite sides. The steel cages 3 include multiple support rods 32 and multiple support columns 31. The support columns 31 are set vertically. The support rods 32 are located between the support columns 31 and template 1 21. The two ends of the support rods 32 along the length direction are fixedly connected to the support columns 31 and template 1 21 respectively. The lower end of the support column 31 near template 2 22 is fixedly connected to template 4 24. The two opposing support columns 31 are connected by the same water-stop screw 33. The water-stop screw 33 clamps and fixes the two support columns 31, thereby clamping and fixing template 1 21 and template 2 22 and extending the water penetration path. The top plate 1 is supported by the support columns 31 through template 4 24, thereby supporting the overall structure.

[0033] During concrete pouring, the concrete flows downwards along formwork 1 (21) and formwork 2 (22), filling the space between formwork 1 (21) and formwork 3 (23) and the upper part of formwork 4 (24) to form the roof panel structure. Finally, the concrete flows and fills the space between formwork 1 (21) and formwork 2 (22) to form the uplift structure wall structure, thus completing the integral pouring of the concrete. Formwork 1 (21) and formwork 2 (22) guide the concrete and fix the formed concrete, reducing the probability of concrete cracking and thus improving the construction stability between the uplift structure wall and the roof panel.

[0034] A shielding member 4 is provided on the lower end of template 22 away from template 1 21. The shielding member 4 extends away from template 1 21 and is parallel to template 4 24. In this embodiment, the shielding member 4 is made of galvanized steel wire mesh. The steel wire mesh can be cut into any shape to adapt to the working conditions. The steel wire mesh intercepts the poured concrete and fixes the formed concrete, reducing the probability of concrete cracking.

[0035] A reinforcing rod 5 is installed between template 1 21 and template 2 22. Two adjacent reinforcing rods 5 between template 1 21 and template 2 22 are arranged crosswise. The two reinforcing rods 5 are rotatably connected to the same rotating rod 51 at the intersection. The reinforcing rod 5 is slidably connected to template 1 21 and template 2 22 in the vertical direction. Template 1 21 and template 2 22 guide and limit the reinforcing rod 5 so that the reinforcing rod 5 can adapt to the spacing between template 1 21 and template 2 22, thereby improving the applicability of the structure. After the water-stop screw 33 is tightened, the angle between the reinforcing rods 5 is initially fixed. The end of the reinforcing rod 5 is equipped with a fixing part 2 7 for fixing the position of the reinforcing rod 5. The rotating rod 51 is equipped with a fixing part 1 6 for fixing the angle of the two reinforcing rods 5. The operator further fixes the reinforcing rod 5 by setting the fixing part 1 6 and the fixing part 2 7, which helps to improve the stability of the reinforcing rod 5 and thus reduce the probability of concrete cracking.

[0036] The fixing component 6 includes two fixing plates 61 and two nuts 62. The two fixing plates 61 are respectively sleeved on both ends of the rotating rod 51 along its length. The two nuts 62 are respectively threaded to one end of the rotating rod 51 that passes through the fixing plate 61. The fixing plate 61 has a limiting groove 611 that is adapted to the reinforcing rod 5. The fixing plate 61 limits the reinforcing rod 5 through the limiting groove 611. The operator tightens the nuts 62 so that the nuts 62 abut against the fixing plate 61. The two nuts 62 cooperate to clamp the fixing plate 61. The two fixing plates 61 cooperate to clamp the reinforcing rod 5 through the limiting groove 611, thereby fixing the angle between the reinforcing rods 5, thereby improving the installation stability of the reinforcing rod 5, and finally fixing the reinforcing rod 5 to the concrete, reducing the probability of concrete cracking.

[0037] The second fixing component 7 includes an abutment plate 71 and bolts 72. The abutment plate 71 is installed at the end of the reinforcing rod 5 and hinged to the end of the reinforcing rod 5. After the angle between the reinforcing rods 5 is fixed, the operator inserts the bolts 72 into the reinforcing plate and template 1 21 or template 2 22 in sequence, and connects them with the template 1 21 or template 2 22 by threads. The head of the bolt 72 abuts against the abutment plate 71. The bolts 72 fix the position of the reinforcing rod 5 on template 1 21 and template 2 22 through the abutment plate 71, which helps to improve the installation stability of the reinforcing rod 5, thereby supporting and reinforcing the concrete and reducing the probability of concrete cracking.

[0038] The support column 31 has several grooves 311 vertically formed along its upper edge to accommodate the support rod 32. The support rod 32 is inserted into the groove 311 and fixedly connected to the inner wall of the groove 311. This helps to improve the installation stability between the support rod 32 and the support column 31, and reduces the probability of the support rod 32 and the support column 31 breaking along the contact surface, thereby improving the overall stability of the device.

[0039] Several bent plates 8 are installed at the upper end of template 424. The bent plates 8 extend from bottom to top to support the concrete. When the concrete cracks after it is formed, water flows along the concrete cracks. The bent plates 8 block the water and extend the water penetration path, reducing the probability of water penetrating into the wall along the concrete.

[0040] The implementation principle of the one-time molding anti-cracking construction of roof panel and upper structure wall in this application embodiment is as follows: the top plate 1 supports the formwork 3 23 and formwork 4 24, and supports the support column 31 through formwork 4 24, thereby supporting formwork 2 22. Formwork 2 22 supports formwork 1 21 through water-stop bolts 33 and support column 31. Formwork 1 21 and formwork 2 22 guide the concrete during concrete pouring, so that the concrete is cast in one piece, and fixes and supports the concrete during the concrete forming process. The reinforcing cage 3 clamps and fixes formwork 1 21 and formwork 2 22 through support column 31 and support rod 32, reducing the probability of concrete cracking, thereby improving the construction stability between the upper structure wall and the roof panel.

[0041] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
