Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a roof rounding corner forming device and a method for constructing roof rounding corners. Background Technology

[0002] In building roofing projects, in order to reduce or avoid cracking of the roof leveling layer and ensure that the roll material or coating is not damaged when bent, the corners of the roof leveling layer need to be processed into rounded arcs so that the waterproof layer will not be pulled apart at the corners.

[0003] In existing construction techniques, forming devices are often used to process roof corners. For example, Chinese patent document CN219909962U discloses an integrated forming device for roof corner rounding, which includes a left support device, a right support device, and a roller pressing device. The left and right support devices are respectively provided with arc-shaped guide grooves that match the curvature of the roof corners on their opposite surfaces. The roller pressing device includes a forming roller and guide shafts coaxially installed at both ends of the forming roller. The two ends of the forming roller are installed in the arc-shaped guide grooves of the left and right support devices through the guide shafts, so that the forming roller can move along the arc-shaped guide grooves. When the guide shaft of the forming roller is placed at the top of the arc-shaped guide groove, the outer wall of the forming roller is tangent to the wall surface. When the guide shaft of the forming roller is placed at the bottom of the arc-shaped guide groove, the outer wall of the forming roller is tangent to the roof surface.

[0004] Although the technical solution disclosed in the aforementioned patent can achieve rapid forming of roof rounded corners, the forming range of the roof rounded corners corresponds to the length of the roller pressing device used, and the length of the roller pressing device is fixed. Therefore, it can only carry out the construction of roof rounded corners of a single length dimension. In the actual construction and pouring process, it is difficult to deal with the pouring of longer sections of roof rounded corners. Although it can be constructed by repositioning multiple times and using a segmented forming method, it will undoubtedly lead to an extension of the construction cycle and a reduction in construction efficiency. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a roof rounding device that can meet the requirements of roof rounding construction work of any length.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this invention is: a roof corner rounding forming device, including a frame and a forming wheel, the forming wheel being detachably mounted on the frame; the forming wheel has a forming surface, which is an arc surface adapted to the shape of the roof corner rounding; the frame is equipped with rollers. This invention, by setting up a frame and a forming wheel with an arc-shaped forming surface, utilizes the movement of the frame driven by the rollers to drive the forming wheel, which is attached to the roof corner, to move repeatedly along the length extension direction of the roof corner. During the movement, the forming wheel repeatedly crushes the concrete poured at the roof corner, ultimately forming the desired roof corner rounding through the forming action of the forming surface; the forming processing direction of this invention is the length direction of the roof corner rounding, and it can be moved as a whole to adapt to the length of the roof corner rounding, thereby achieving one-time forming of the roof corner rounding, exhibiting good adaptability, effectively improving the construction efficiency of roof corner rounding and reducing the construction cycle.

[0007] As an improvement to the above solution: the forming wheel is a hemispherical structure with an arc surface and a flat surface at its two ends. The forming wheel is vertically mounted on the frame with the flat end surface as the vertical plane. The movement path of the frame driven by the rollers is parallel to the flat end surface of the forming wheel. The outer diameter of the flat end surface of the forming wheel is larger than the maximum outer diameter of the arc surface end surface. This invention uses a hemispherical forming wheel, which reduces its space occupation and cost compared to spherical or other structural forming wheels. At the same time, widening the outer diameter of the flat end surface of the forming wheel allows this end edge to form a limiting edge. During the movement of the device, the limiting edge can be inserted into the partition joint of the wall to form a limiting fit, constraining the movement path of the device to ensure that its movement does not deviate. At the same time, the limiting edge can also prevent concrete slurry from overflowing, thereby improving the forming quality.

[0008] As an improvement to the above solution: the frame is detachably connected to a first component and a second component; the first and second components are respectively spaced apart on both sides of the forming disc and connected to each other to form a surrounding structure adapted to the outer contour shape of the forming disc; each of the first and second components is provided with a roller. The frame in this invention adopts a detachable surrounding structure composed of a first component and a second component, which facilitates the assembly and disassembly of the forming disc, while not affecting the contact between the forming disc and the roof angle, thus providing sufficient construction space for the forming of the roof rounded corners.

[0009] As an improvement to the above solution: both the first and second components are hollow tubular structures, and the connection between the first and second components is formed by a plug-in joint with the hollow tubular body to create a detachable connection. This plug-in joint effectively reduces the assembly difficulty of the skeleton and improves its assembly efficiency.

[0010] As an improvement to the above solution, a central shaft is also included. The central portion of the forming wheel has a through hole that fits with the central shaft with a clearance fit. The central shaft passes through the through hole and rotatably engages with the frame. This invention, by adding a central shaft, utilizes the clearance fit between the central shaft and the central through hole on the forming wheel to achieve rotation of the forming wheel. Compared to a fixed-position structure for the forming wheel, the angle between the forming wheel and the roof is transformed into rolling friction, resulting in a smoother forming process and better shaping effect for roof corners.

[0011] As an improvement to the above solution: the end of the plug-in part and the first or second component that cooperates with the plug-in part are provided with a connecting hole coaxially arranged with the central shaft, and the central shaft passes through the plug-in part and the connecting hole of the first or second component at the same time.

[0012] As an improvement to the above solution, it also includes a telescopic support rod fixed to the frame. The telescopic support rod consists of multiple rods perpendicular to the frame and connected in a telescopic manner. The bottom rod is threaded to the frame, and an auxiliary wheel is provided on the top rod. This invention supports the frame by adding a telescopic support rod, allowing the molding device to be hung on the top of the wall. The overall length of the telescopic support rod can be adjusted by telescopic movement to adapt to the wall height. The auxiliary wheel at the top of the telescopic support rod can support itself on the top of the wall and slide along the top of the wall during the molding process, thereby improving the stability of the molding device's movement.

[0013] The present invention also discloses a construction method for rounded corners of a roof, using the roof rounded corner forming device described above; during construction, the roof rounded corner forming device is placed at the corner of the roof to be constructed, so that the forming surface of the forming wheel fits into the corner of the roof. After pouring concrete to the corner of the roof, the frame is repeatedly pushed to drive the forming wheel to roll repeatedly along the extension direction of the corner of the roof until the roof rounded corner is formed.

[0014] The beneficial effects of this invention are as follows: By setting up a frame and a forming wheel with an arc-shaped forming surface, the frame, driven by rollers, moves repeatedly along the length of the roof corner, causing the forming wheel to repeatedly roll and compact the concrete poured at the roof corner during the movement. The forming surface then shapes the desired roof rounded corner. The forming direction of this invention is the length of the roof rounded corner, and the entire assembly can be moved to adapt to the length of the roof rounded corner, thus achieving one-time forming of the roof rounded corner. This invention has good adaptability, effectively improving the construction efficiency of roof rounded corners and reducing the construction cycle. Attached Figure Description

Detailed Implementation

[0019] To facilitate understanding of the present invention, the invention will be further described below with reference to the accompanying drawings.

[0020] In the description of this invention, it should be noted that the terms "front", "rear", "left", "right", "up", "down", "inner", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0021] like Figure 1 and Figure 2 As shown, the roof rounding corner forming device disclosed in this invention includes a frame 100 and a forming wheel 200. The frame 100 is used to mount the forming wheel 200, which is used to process the roof corners to form rounded roof corners. The forming wheel 200 has a forming surface, which is an arc surface. The curvature and other dimensions of the arc surface are set according to the parameters of the required roof rounded corner, so that the forming surface can match the shape of the formed roof rounded corner. The forming wheel 200 and the frame 100 are assembled in a detachable connection manner, facilitating the selection and replacement of the appropriate size forming wheel 200 according to the parameter differences of the construction object. Rollers 300 are installed on the frame 100, which can drive the frame 100 to move. The forming wheel 200 moves together with the frame 100, continuously compacting and shaping the poured concrete as it moves with the frame 100, forming a rounded roof corner at the corner of the wall 600.

[0022] Furthermore, the forming wheel 200 used in this invention is a hemispherical structure, but other structures with curved surfaces can also be used, such as spherical, elliptical, or olive-shaped structures. Since the curved surface of the forming wheel 200 plays a decisive role in forming the rounded corners of the roof, other non-critical parts can be omitted. Therefore, this invention always prefers a hemispherical structure with curved and flat ends, respectively, which can reduce the overall size of the forming wheel 200 and reduce production costs. When the forming wheel 200 is vertically set on the frame 100, the flat end face of the forming wheel 200 is vertical, so that the movement path of the frame 100 driven by the roller 300 is parallel to the flat end face of the forming wheel 200. This also facilitates the design and assembly of the frame 100. Compared with other irregular or non-planar end faces, the corresponding parts of the frame 100 can be set as regular structures, and the distance between the flat end face and the frame 100 is equal, making the processing of the frame 100 more convenient.

[0023] Because the concrete slurry compacted by the forming wheel 200 during the roof corner rounding process is not completely solidified, the concrete slurry will overflow beyond the processing range due to the pressure from the forming wheel 200, causing not only waste of raw materials but also potentially resulting in incomplete forming surfaces. To prevent this overflow, the present invention further optimizes the structure of the forming wheel 200 by adding a limiting protrusion to its edge. This limiting protrusion is formed by machining the outer diameter of the flat end face of the forming wheel 200 to be larger than the maximum outer diameter of the curved end face. The addition of the limiting protrusion can block the concrete slurry to prevent overflow and reduce waste. Simultaneously, the limiting protrusion can also be inserted into the wall's partition joint to form a limiting fit, thereby limiting the overall movement path of the roof corner rounding device and preventing it from tilting during movement.

[0024] like Figure 1 and Figure 2As shown, the frame 100 used in this invention is a detachable structure composed of a first component 110 and a second component 120. The specific shapes of the first component 110 and the second component 120 are not limited, as long as they can be assembled to form the structure for mounting the forming disc 200. The first component 110 and the second component 120 in this application adopt a symmetrical tubular structure. By separately arranging the first component 110 and the second component 120 on both sides of the forming disc 200 and connecting them to form a surrounding structure adapted to the outer contour shape of the forming disc 200, and by providing a roller 300 below each of the first component 110 and the second component 120 to achieve balanced movement, the mounting positions of the first component 110 and the second component 120 correspond to the middle of the forming disc 200. The mounting structure of the roller 300 supports the frame 100, suspending it in the air to avoid contact with the concrete during movement and thus affecting the forming of the roof's rounded corners.

[0025] Furthermore, in this invention, the detachable connection between the first component 110 and the second component 120 is achieved by a plug-in structure. The plug-in structure is a plug-in part 130 fixed at the connection between the first component 110 and the second component 120. In conjunction with the hollow tube structure of the first component 110 and the second component 120, the connection between the first component 110 and the second component 120 can be conveniently achieved by inserting the plug-in part 130 into the port at the connection between the first component 110 and the second component 120.

[0026] Furthermore, in order to facilitate the insertion of the plug-in part 130, the end of the plug-in part 130 can be set as an arc-shaped end, and the arc surface of the end of the plug-in part 130 can guide the insertion action.

[0027] In this invention, the molding wheel 200 can be installed on the frame 100 using either a fixed connection or a rotatable connection, with the rotatable connection being the preferred option. When using a fixed connection, the molding wheel 200 does not rotate as it moves with the frame 100, and its molding of concrete relies solely on pushing the concrete. However, when using a rotatable connection, the molding wheel 200 rotates as it moves with the frame 100, and the molding wheel 200 creates a rotating and compacting effect while pushing the concrete, resulting in a better molding effect and higher quality of the roof rounded corners.

[0028] Specifically, when the forming disc 200 is rotatably mounted on the frame 100, this is achieved by adding a central shaft 400. For example... Figure 1 and Figure 2As shown, a through hole 210 radially penetrating the center of the forming wheel 200 is provided, and a central shaft 400 with an outer diameter slightly smaller than the diameter of the through hole 210 is used. The central shaft 400 passes through the through hole 210 of the forming wheel 200 to form a clearance fit, so that the central shaft 400 and the forming wheel 200 can rotate relative to each other. The central shaft 400 is then installed on the frame 100 by a fixed connection or a rotatable connection. The insertion part 130 and the end of the first component 110 or the second component 120 that cooperates with the insertion part 130 are provided with connecting holes coaxially arranged with the central shaft 400. The central shaft 400 passes through the insertion part 130 and the connecting holes of the first component 110 or the second component 120.

[0029] To further improve the stability of the roof rounding forming device during the moving forming process, the present invention also provides a telescopic support rod 500 on the frame 100, which is used to hang the frame 100 on the wall 600. Figures 1 to 3 As shown, the telescopic support rod 500 is fixed to the frame 100 using a threaded connection. A threaded joint can be installed on the frame 100, and an internal threaded hole is provided at the bottom of the telescopic support rod 500. An auxiliary wheel 510 is provided at the top of the telescopic support rod 500. When the frame 100 is moved by the roller 300, the auxiliary wheel 510 at the top of the telescopic support rod 500 rolls synchronously on the top of the wall 600, ensuring that the roof corner rounding device is close to the wall 600. The overall length of the telescopic support rod 500 can be adjusted to accommodate walls 600 of different heights. The telescopic support rod 500 consists of multiple rods perpendicular to the frame 100 and connected in a telescopic manner. Each rod can be locked together using locking screws. The bottom rod is threadedly connected to the frame 100, and the auxiliary wheel 510 is provided on the top rod.

[0030] This invention also discloses a construction method for rounding roof corners using the aforementioned roof corner forming device. During construction, a forming wheel 200 of the corresponding specification is selected according to the required arc and other dimensions of the roof corner to be rounded. The length of the telescopic support rod 500 is adjusted according to the height of the wall 600, and then the roof corner forming device is assembled. The assembled roof corner forming device is placed at the required roof corner, so that the forming wheel 200 is in contact with the wall. Concrete is poured at the roof corner, and an auxiliary plate 620 is laid on a horizontal surface, leaving a gap 630 between the auxiliary plate 620 and the concrete. The limiting protrusion of the forming wheel 200 is inserted into the gap 630 and in contact with the edge of the auxiliary plate 620. The roof corner forming device is repeatedly pushed along the extension direction of the roof corner until the roof corner 610 is formed. Finally, the surface is manually finished to complete the construction of the roof corner.
