Description

Technical Field

[0001] The invention relates to the technical field of parapet wall construction, and in particular to a processing mould for a roof R-corner flashing prefabricated plate. Background Art

[0002] In construction projects, the waterproof treatment of the parapet wall at the junction with the roof is crucial. The traditional method of treating the flashing of the parapet wall is to open a groove on the side wall of the flashing surface of the parapet wall, extend the waterproof membrane into the groove and fill it with sealing material, and finally apply a mortar layer. However, with the complexity of construction projects and the improvement of waterproofing requirements, the traditional flashing treatment method has gradually exposed the following technical defects: Since the flashing of the parapet wall is in an arc shape, it depends on the workers' experience to adjust, which is prone to R angle deviation, resulting in reduced on-site construction quality, increased risk of joint leakage, and directly affecting the reliability of the roof waterproofing system.

[0003] Patent "201821086067.1" discloses a rapid processing mold for prefabricated panels with R-angled flashing on roofs. This solution forms a closed space with the same structure as the prefabricated panel through the coordination of multiple structures such as curved panels, baffles, upper edge sealing, lower edge sealing and cover panels, forming a mold for making prefabricated panels. However, this solution has the following defects. For example, this solution achieves single curvature shaping by fixing the curved panels and baffles, and cannot adapt to different R-angle size requirements. In actual projects, different projects or different areas of the same roof have different requirements for flashing curvatures, and special molds need to be customized repeatedly, resulting in large mold inventory, high repeated investment costs, and poor flexibility in prefabricated panel production, which seriously affects construction efficiency. In addition, the baffles and curved panels are rigidly fixed, which makes it inconvenient to disassemble the formed model when removing the mold; based on this, it is necessary to study a processing mold for prefabricated panels with R-angled flashing on roofs. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a processing mold for a roof R-corner flashing prefabricated panel, which effectively solves the existing problems of poor versatility, complex mold removal, and high dependence on manual labor.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a processing mold for a roof R-angle flashing prefabricated plate, comprising a base template, a side plate and an adjustment template, the front end of the base template is vertically upwardly provided with a stop platform, the adjustment template comprises an arc plate, a flexible pad and a fastening shaft, the adjacent sides of the multiple arc plates are hinged together in sequence to form a deformable template that can adapt to different R angle changes; the middle part of the arc plate is fixed with a fastening shaft, and the fastening shafts on the left and right sides extend outward from the outer arc plate to form a connecting section; the flexible pad is provided with a fixing plate, and the fixing plate ... The pad is tightly fixed on the inner wall of the deformable template, and its top extends outward and is fixed on the arc plate; a positioning hole is opened on the side plate, and the connecting sections on both sides of the central axis are respectively adapted to be fitted in the positioning holes, and the side plates are fitted and locked with the sides of the arc template by locking nuts; when the side plates are fixed and blocked on the left and right sides of the base, the lower end of the flexible pad is folded outward and fixed on the baffle, so that the deformable template, the base template and the two side plates together enclose the casting space of the prefabricated plate, and a grouting port is reserved at the top of the casting space.

[0006] Furthermore, a bending portion is provided at the end of the side panel, and a screw hole is opened on the bending portion. When the side panels are installed on the left and right sides of the basic template, the side panels are fixed on the basic template by tightening bolts.

[0007] Furthermore, a connecting plate is provided on the rear side of the basic template, and the screw holes on the bending portion correspond to the screw holes on the connecting plate.

[0008] Furthermore, diagonal braces are provided at intervals on the rear side wall of the base formwork connecting plate.

[0009] Furthermore, the connection section on the fastening shaft is threaded, and the locking nut screwed on the fastening shaft can tightly fit the side plate to the side of the deformable template, so that the deformation state of the deformable template corresponds to the positioning hole.

[0010] Furthermore, the arc-shaped plate at the top and the arc-shaped plate at the bottom constituting the deformable template are arranged in parallel in the horizontal direction, and the arc-shaped plate at the middle position is arranged at an angle.

[0011] Furthermore, a slot is opened in the middle of the arc-shaped plate at the top, and the slot is connected to the inside of the casting space to serve as a grouting port.

[0012] Furthermore, a transition platform is provided on the front side of the basic formwork, so that the rear side of the precast panel cast in the casting space presents an inclined structure.

[0013] Furthermore, adjacent arc-shaped plate side walls are hinged together through a hinge structure.

[0014] Furthermore, a handle is provided on the side panel.

[0015] The beneficial effect of the above technical solution is: the processing mold of the roof R-corner flashing prefabricated panel proposed by the present invention, wherein the adjustment template adopts a multi-section hinged arc plate structure, adjacent arc plates are connected by bottom hinges, and can rotate freely around the hinge axis to form a deformable template with continuously adjustable curvature, thereby realizing flexible adjustment of the curvature.

[0016] A flexible pad is laid on the inner side of the deformable formwork of the present invention. The material of the flexible pad has flexibility, wear resistance, corrosion resistance and low adhesion to concrete to ensure its stable performance and easy demolding during use, such as rubber skin and polyurethane skin, and the surface of the flexible pad on the side adjacent to the casting space needs to have a certain rigidity to cover the gap between adjacent arc plates to form a rigidly supported flat inner wall, and the top of the flexible pad is folded and fixed to the arc plate, and the bottom is folded and overlapped on the basic formwork baffle to form a continuous sealing surface, thereby eliminating the gap between the hinged arc plates, ensuring that the inner wall of the casting space is smooth, and avoiding leakage of concrete slurry or uneven molding surface.

[0017] The preset positioning holes on the side panels match the fastening shafts on the curved panels. By adjusting the position of the fastening shafts in the positioning holes, the curvature of the deformable template can be quickly locked to ensure the consistency of the R angle of the prefabricated panels, so that the mold can quickly adapt to the R angle curvature requirements of different projects and meet the diverse needs of complex roof flashing designs. When the R angle curvature of the precast panel needs to be adjusted, it is only necessary to re-open a positioning hole corresponding to the target curvature on the side panel, and pass the fastening shaft on the curved plate through and lock it on the new positioning hole. This design realizes the flexible adjustment of the curvature of the deformable template to meet the needs of different projects.

[0018] In the present invention, the side panels and the deformable template are combined into an integral module, which is quickly connected to the base template by fastening bolts, thereby simplifying the mold installation process and facilitating the mold removal operation, significantly shortening the construction period, significantly reducing construction costs, and improving the quality of prefabricated panels and engineering applicability.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Embodiment 1, this embodiment aims to provide a processing mold for a roof R-corner flashing prefabricated board, which is mainly used for the processing and production of the flashing prefabricated board at the R-corner of the roof, which is very important for the waterproofing project at the inner corner of the roof and the parapet. The traditional method of directly pouring the R-corner manually is prone to cause inconsistent arc angles in different areas, thereby affecting the construction quality. Although the prefabricated board processing mold disclosed in the prior art can solve the problem of inconsistent curvature, it is not convenient to remove the mold after the prefabricated board is cast, and most of them can only produce one R-corner curvature size. If it is necessary to change the R-corner size, a new mold needs to be remade, which is less practical and less flexible. Therefore, the present invention proposes a processing mold for a roof R-corner flashing prefabricated board, which is easy to use, has an adjustable R-corner curvature, and can flexibly adapt to the production of prefabricated boards under different curved surfaces.

[0022] like Figure 1-3 As shown, the processing mold for the roof R-angle inverted flashing prefabricated panel provided in this embodiment includes a base template 1, a side panel 3 and an adjustment template. In this embodiment, the cross-section of the base template 1 is a right-angle structure. In actual application, the front angle of the base template 1 can also be adaptively adjusted according to the actual situation at the construction site. A baffle 2 is vertically upwardly provided at the front end of the base template 1. The baffle 2 is integrally formed with the base template 1 and serves as a bottom closure of the casting space 15 to ensure the bottom sealing during the casting process and prevent leakage. A connecting plate 13 is fixed to the rear side of the base template 1. The left and right sides of the connecting plate 13 extend outward respectively for fixed connection with the side panel 3. Furthermore, diagonal braces 14 are also arranged at intervals on the rear side of the connecting plate 13 to maintain the stability of the base template 1.

[0023] like Figure 1 and 3As shown, the adjustment template is arranged above the base template 1. In this embodiment, the adjustment template includes an arc plate 6, a flexible pad 9 and a fastening shaft 12, wherein the front and rear adjacent sides of the multiple arc plates 6 are hinged together in sequence to form a deformable template 8 that can adapt to different R-angle changes. In the specific structure, the adjacent arc plates 6 are hinged together once through the hinge structure at the bottom, so that each arc plate 6 can rotate around the hinge axis in the hinge, so that when the multiple arc plates 6 are hinged together, a deformable template 8 that can undergo different morphological changes is formed. The construction personnel only need to move the arc plate 6 and adjust it to the required curvature to quickly adapt to the processing requirements of prefabricated panels with different R-angle sizes, which significantly improves the versatility and construction efficiency of the mold.

[0024] like Figure 4 As shown, a fastening shaft 12 is symmetrically fixed in the middle of the arc plate 6, and the fastening shafts 12 on the left and right sides of the arc plate 6 extend outward to form connecting sections, which are threaded and used to adapt and connect with the positioning holes 5 on the side plates 3, thereby achieving the shaping of the deformable template 8.

[0025] like Figure 2 and Figure 4 As shown, a flexible pad 9 is fixed on the inner side of the deformable template 8 so that the flexible pad 9 is tightly attached to the adjacent side of the deformable template 8, the width of the flexible pad 9 is adapted to the width of the deformable template 8, and the front and rear ends of the flexible pad 9 extend to the outside of the deformable template 8. Specifically, the topmost arc plate 6 and the bottommost arc plate 6 constituting the deformable template 8 are arranged in parallel in the horizontal direction, the arc plate 6 in the middle position is at a certain angle, and a slot is also opened in the middle of the arc plate 6 at the top, which is connected to the inside of the casting space 15 and is used as a grouting port 11 to grout into the precast plate casting space 15 surrounded by the deformable template 8, the base template 1 and the two side plates 3.

[0026] The top of the flexible pad 9 extends from the gap between the topmost arc plate 6 and the adjacent arc plate 6, and is folded toward the rear side, and the top of the flexible pad 9 is fixed to the arc plate 6 by the fixing bolts 10; when the deformable template 8 is installed above the base template 1, the bottom of the flexible pad 9 extends upward from the gap between the front end edge of the deformable template 8 and the baffle 2 of the base template 1, and is folded forward and overlapped on the top of the baffle 2, and is fixed to the baffle 2 by the fixing bolts 10.

[0027] The adjustable template of the present invention is set up like this. After the curvature deformation of the deformable template 8 is determined according to actual conditions, the deformable template 8 is supported by the flexible pad 9 on its inner side. At the same time, due to the hinge structure between adjacent curved plates 6, when the adjustable template and the side plate 3 are installed on the base template 1 to jointly form a casting space 15 with a hollow inner cavity, the surface of the formed precast board will be uneven. Therefore, by laying the flexible pad 9 in the deformable template 8, and the flexible pad 9 and the adjacent side surface of the casting space 15 are set in a rigid structure, the surface of the cast precast board can be made smoother, and the sealing of the casting space 15 can be further ensured.

[0028] like Figure 5 As shown, the side panels 3 are symmetrically arranged on the left and right sides of the base template 1, and are used to block the left and right sides of the base template 1. In this embodiment, the rear side of the side panel 3 is folded outward to form a bending portion 4, and screw holes are sequentially opened vertically on the bending portion 4, and the screw holes on the bending portion 4 correspond to the screw holes on the left and right sides of the connecting plate 13 on the base template 1. Therefore, after the deformable template 8 is installed on the side panel 3, the side panel 3 can be installed on the left and right sides of the base template 1 by tightening the bolts 7 to form a casting space 15 for the production of prefabricated panels. Figure 5 As shown, in this embodiment, a pull handle 16 is further provided on the side plate 3 to facilitate the removal of the side plate 3 and the adjustment template as a whole from the base template 1 when removing the template.

[0029] Furthermore, a positioning hole 5 is obliquely provided on the side panel 3, and the inner diameter of the positioning hole 5 is adapted to the inner diameter of the fastening shaft 12 on the arc plate 6 so that the fastening shaft 12 can pass through, and when the side panels 3 on both sides are installed on both sides of the deforming template 8, the side panels 3 can be tightly clamped on both sides of the deforming template 8 by screwing the locking nuts on the fastening shaft 12.

[0030] With such an arrangement, the positioning hole 5 provides a precise positioning reference for the fastening shaft 12. The fastening shaft 12 passes through the positioning hole 5 on the side plate 3, and the side plate 3 is clamped to the deformable template 8 by the locking nut, ensuring that the curvature of the deformable template 8 is consistent with the preset R angle. In addition, the locking nut screwed on the fastening shaft 12 can make the side plate 3 fit tightly with the side of the deformable template 8, so that the deformation state of the deformable template 8 corresponds to the positioning hole 5, thereby realizing rapid shaping of the deformable template 8; further, the axial pressure applied by the locking nut makes the side plate 3 fit tightly with the side of the deformable template 8, eliminating the gap, enhancing the sealing and structural stability of the casting space 15, and preventing the displacement or deformation of the deformable template 8 during the casting process.

[0031] Therefore, when faced with the adjustment of different R angle radians, it is only necessary to change the position of the positioning hole 5 on the side plate 3 to quickly adjust the radian of the deformable template 8, without the need to re-make the mold, which significantly reduces the mold inventory and repeated investment costs, thereby meeting the size requirements of different R angles, reducing the frequency of mold replacement, shortening the construction preparation time, and improving construction efficiency. In addition, through the modular design of the positioning hole 5 and the fastening shaft 12, the worker only needs to adjust the position of the fastening shaft 12 according to the preset radian and lock it to complete the mold adaptation. The operation is simple and efficient, reducing the dependence on the worker's experience and reducing the quality problems of the prefabricated panels caused by operational errors.

[0032] Moreover, the side panel 3 and the deformable template 8 are tightly connected through the fastening shaft 12 and the locking nut to form a stable overall structure, which can resist the lateral pressure during the pouring process, prevent the mold from deforming, further enhance the sealing of the pouring space 15, avoid leakage of concrete slurry, and ensure that the surface of the precast panel is smooth and flat.

[0033] Description of working principle: The processing mold of the roof R-angle inverted flashing prefabricated plate provided in this embodiment, when making the flashing prefabricated plate, according to the R-angle curvature required by the design, a positioning hole 5 corresponding to the target curvature is pre-opened on the side plate 3, and the inner diameter of the positioning hole 5 is adapted to the inner diameter of the fastening shaft 12 on the arc plate 6 to ensure the accuracy of subsequent connection and positioning. Then, the deformation template 8 composed of multiple hinged arc plates 6 is placed between the side plates 3, so that the fastening shaft 12 on the arc plate 6 passes through the positioning hole 5 on the side plate 3, and the side plate 3 is tightly clamped on both sides of the deformation template 8 by screwing the locking nut to ensure that the curvature of the deformation template 8 is consistent with the preset R angle. At this time, the side plate 3 and the deformation template 8 are combined into an integral module.

[0034] Afterwards, install the assembled side panel 3 and deformable template 8 module on the base template 1, so that the screw holes on the side panel bending part 4 correspond to the screw holes on the connecting plate 13 of the base template 1, and fix them together and lock them by fastening bolts 7 to form a stable casting space 15, check whether the top and bottom of the flexible pad 9 are folded and fixed on the arc plate 6 and the baffle 2 respectively, to ensure the sealing of the casting space 15.

[0035] After spraying the release agent into the casting space 15, pour concrete slurry into the casting space 15 through the grouting port 11 on the top of the deformable template 8. After the slurry fills the casting space 15, vibrate and compact it to ensure that there are no bubbles inside the precast panel and the surface is smooth. Figure 2 The left figure shows the structural schematic diagram of the pouring space. Concrete is poured into the pouring space. After it is formed and demoulded, the structure of the precast panel is as follows: Figure 2As shown in the right figure. In the present invention, a transition platform is provided on the front side of the foundation formwork, so that the rear side of the precast panel cast in the casting space is an inclined structure. During actual construction, wooden squares are inserted in the area between the inclined surface on the precast panel and the parapet as a temporary support and positioning structure, and mortar is filled between the rear side of the precast panel and the parapet, thereby achieving a close connection and firm installation between the precast panel and the main structure, significantly increasing the bonding between the precast panel and the main structure, solving the gaps that are easy to appear in traditional installations, and the problem of poor bonding during straight corner construction, and enhancing the stability, durability and waterproof effect of the overall structure.

[0036] In order to ensure the uniformity of concrete slurry vibration, a micro vibrator can be installed on the connecting plate 13 of the base formwork 1 in actual application (this is the prior art and will not be repeated here), so that vibration can be performed during the concrete pouring process to make the concrete more compact and improve the quality of the precast panel.

[0037] After the concrete is initially set, loosen the locking nut and the fastening bolt 7, and use the handle 16 on the side panel 3 to remove the side panel 3 and the deformable template 8 from the base template 1. Due to the flexible transition design of the flexible pad 9, the deformable template 8 can be easily separated from the precast panel. If you need to make a precast panel with a different R angle, you only need to readjust the position of the positioning hole 5 on the side panel 3 and repeat the above steps without changing other molds.

[0038] The processing mold for the roof R-angle flashing prefabricated panel provided by the present invention realizes rapid adjustment and high-precision shaping of the mold, significantly improves the versatility of the mold, construction efficiency and quality stability of the prefabricated panel, effectively reduces construction costs, and the R-angle curvature of the prefabricated panel is precisely controllable and has high dimensional consistency, which reduces the risk of joint misalignment and leakage during on-site assembly, improves the overall reliability of the waterproof layer, and improves the quality of the prefabricated panel and engineering applicability.

[0039] Embodiment 2: Based on Embodiment 1, this embodiment further illustrates the installation structure of the flexible pad.

[0040] The flexible pad 9 and the deformable template can be fixedly installed by directly sticking the flexible pad 9 together through an adhesive material, or the structural connection method provided in this embodiment can be used, such as Figure 6As shown, a flat hole 18 is opened in the middle of the arc plate, and a connecting bolt 17 is vertically fixed on the adjacent side walls of the flexible pad 9 and the arc plate. The connecting bolt 17 is passed through the flat hole 18 and extends to the outside of the arc plate, and is locked on the arc plate by a nut, thereby ensuring a fixed connection between the flexible pad 9 with a certain thickness and the deformation template, so that the inner side of the flexible pad 9 is tightly attached to the deformation template. At the same time, when the deformation template adapts to the R-angle deformation, due to the existence of the flat hole 18, it will not affect the connection and fixation of the flexible pad 9 and the arc plate, thereby ensuring that the flexible pad 9 is away from the wall on one side of the deformation template. Smooth.

[0041] With such arrangement in the present embodiment, the flat hole provides a certain moving space for the connecting bolt. When the deformable template adapts to different R-angle curvatures, the connecting bolt can slide in the flat hole to avoid loosening or breaking of the connection due to changes in curvature, so that the flexible pad can be naturally adjusted with the change in curvature of the deformable template, ensuring that the inner side of the flexible pad is always in close contact with the deformable template and the outer wall surface remains smooth to avoid wrinkles or gaps caused by changes in curvature. The connection structure is stable and reliable and can be disassembled and used multiple times, thereby reducing construction costs.

[0042] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. The basic concept of the present invention is to adjust the deformable template in real time as the curvature of the positioning hole on the side plate changes, so as to adapt to the shape and size of the R angle at different positions, without the need to re-formulate all molds, effectively reducing construction costs, and significantly improving construction quality and flexibility. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
