Description

Technical Field

[0001] This utility model relates to the field of casting formwork technology, and more specifically, to a base plate chamfering reinforcement structure. Background Technology

[0002] When beveling the base slab, wooden formwork or precast formwork is usually made on-site for pouring.

[0003] While on-site fabrication of wooden formwork is convenient due to readily available materials, it also has significant drawbacks. The fabrication process is cumbersome and time-consuming, undoubtedly slowing down the overall construction progress. During formwork removal, issues such as the adhesion between the wooden formwork and concrete make operation extremely inconvenient, resulting in a low turnover rate. Furthermore, the forming quality is difficult to control, with frequent instances of formwork bulging, leading to uneven concrete structures and affecting project quality. In addition, the numerous pouring joints not only increase subsequent treatment procedures but also easily become potential sources of leakage.

[0004] While precast formwork can ensure the accuracy of pouring to a certain extent, its limitations are also significant. It is usually customized according to the chamfer dimensions of a specific project, and the chamfer specifications vary greatly between different projects. This means that a single set of precast formwork can often only be used for one project, resulting in poor versatility, low formwork utilization, resource waste, and increased construction costs.

[0005] The above shortcomings need to be improved. Summary of the Invention

[0006] To solve or alleviate the problem of inconvenience in using existing casting formwork, this utility model provides a base plate chamfering reinforcement structure.

[0007] The technical solution of this utility model is as follows:

One of the support plates is provided with a first connecting hole for connecting to the shaping connector, and the other support plate is provided with a second connecting hole for connecting to the shaping connector. The first connecting hole or the second connecting hole is an oblong hole.

The first movable rod and the second movable rod are rotatably connected to two adjacent support plates, and the two ends of the adjusting rod are threadedly connected to the first movable rod and the second movable rod, respectively. The thread direction of the first movable rod is opposite to that of the second movable rod.

[0011] Furthermore, the support plate is provided with multiple through holes, and the support plate is provided with a movable cover plate at the through holes. The first side of the movable cover plate is hinged to the support plate, and the second side of the movable cover plate is connected to the support plate through a movable pin.

[0012] Furthermore, the connecting surface of the support plate is provided with stiffening plates, which include transverse stiffening plates and longitudinal stiffening plates.

[0013] Furthermore, a third connecting hole is provided on the rib plate at the edge of the support plate, and a fastener is provided in the third connecting hole for connecting two adjacent chamfer templates.

[0014] Furthermore, tie rods are provided on the two support plates, and a protective tube is sleeved between the two support plates on the tie rods.

[0015] Furthermore, the support plate is provided with positioning holes, and a first positioning bar connected to the reinforcing cage is provided in the positioning holes.

Detailed Implementation

[0025] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] like Figures 1 to 4 As shown, a bottom plate chamfering reinforcement structure in one embodiment of the present invention includes a chamfering template 100. The chamfering template 100 includes a plurality of support plates 11 connected in sequence. The support surfaces of the plurality of support plates 11 are covered with flexible model plates 12. An angle shaping member 13 is provided on the connecting surface of adjacent support plates 11. The angle shaping member 13 is used to adjust the included angle of adjacent support plates 11.

[0028] First, according to the chamfer angle required by the design, the included angle between adjacent support plates 11 is precisely adjusted by operating the angle fixing component 13 set on the connecting surface of adjacent support plates 11 to make it perfectly match the required angle. For example, if the design is a 45° chamfer, the angle fixing component 13 is rotated until the adjacent support plates 11 form a 45° included angle. During the included angle adjustment process, since the flexible model plate 12 covers the supporting surface of the support plate 11 and the flexible model plate 12 can be bent and deformed, the flexible model plate 12 will bend and deform with the change of the included angle of the adjacent support plates 11. The flexible model plate 12 wraps around the joint of the adjacent support plates 11 to form a continuous and seamless casting model surface. At this time, concrete pouring can be carried out. After the concrete has solidified and reached the demolding strength, the chamfer template 100 is removed.

[0029] In terms of molding quality, the flexible formwork panel 12 ensures the integrity of the chamfered template 100 model surface, avoiding numerous casting joints like traditional wooden formwork, reducing leakage points, and resulting in a smooth and flat chamfered surface, significantly improving molding quality. Regarding construction efficiency, compared to on-site wooden formwork fabrication, it eliminates the need for extensive assembly time; components can be quickly assembled, greatly shortening pre-construction preparation time. Furthermore, convenient demolding increases formwork turnover rate. In terms of adaptability, the angle adjustment via the angle-fixing component 13 allows for application to projects with chamfers of different sizes. Compared to precast formwork that can only be used for specific projects, this improves formwork utilization and reduces construction costs.

[0030] In practical applications, the flexible model board 12 can be made of rubber, bamboo plywood, fiberglass board, resin board, etc. Adjacent support boards 11 are connected by hinges.

[0031] like Figure 2 and Figure 3 As shown, in a preferred embodiment, the angle shaping component 13 includes a shaping connector 131. The two ends of the shaping connector 131 are respectively connected to two adjacent support plates 11 by fasteners. One support plate 11 is provided with a first connecting hole 132 for connecting to the shaping connector 131, and the other support plate 11 is provided with a second connecting hole 133 for connecting to the shaping connector 131. The first connecting hole 132 or the second connecting hole 133 is an oblong hole.

[0032] When adjusting the included angle between adjacent support plates 11, firstly, one end of the shaping connector 131 is fixedly connected to the support plate 11 with the first connecting hole 132 using fasteners. Next, the other end of the shaping connector 131 is aligned with the second connecting hole 133 on the other support plate 11. Since one of the connecting holes is oblong, this facilitates adjustment. For example, to increase the included angle between adjacent support plates 11, simply move the shaping connector 131 along the length of the oblong hole to a suitable position, and then fasten it to the support plate 11 using fasteners. Thus, by flexibly moving and fixing the shaping connector 131 within the oblong hole, the included angle between adjacent support plates 11 can be changed to meet various chamfer angle design requirements, making the operation convenient and efficient.

[0033] In terms of adaptability, no matter how the chamfer angle required by the project changes, the position of the fixed connector 131 in the waist-shaped hole can be quickly adjusted, which makes the entire base plate chamfer reinforcement structure widely applicable to various complex and ever-changing construction scenarios.

[0034] In practical applications, flange bolts can be used as fasteners. Flange bolts can improve the stability of the connection and ensure the structural stability of the chamfered template 100, thereby ensuring the construction quality.

[0035] Or, such as Figure 4 As shown, in a preferred embodiment, the angle shaping component 13 includes a first movable rod 134, a second movable rod 135, and an adjusting rod 136. The first movable rod 134 and the second movable rod 135 are rotatably connected to two adjacent support plates 11, respectively. The two ends of the adjusting rod 136 are threadedly connected to the first movable rod 134 and the second movable rod 135, respectively. The thread direction of the first movable rod 134 is opposite to that of the second movable rod 135.

[0036] During the initial construction preparation phase, one end of the first movable rod 134 is rotatably connected to a support plate 11 using a pin, ensuring that the first movable rod 134 can rotate flexibly relative to the support plate 11. Similarly, one end of the second movable rod 135 is also rotatably connected to the adjacent support plate 11 using a pin. After preparation, the adjusting rod 136 is picked up, and its two ends are respectively fitted onto the pre-set threaded rods on the first movable rod 134 and the second movable rod 135, and manually screwed in to initially fix the adjusting rod 136 to the two rods, forming a connected whole. When it is necessary to adjust the included angle of adjacent support plates 11 according to design requirements, to increase the included angle, the construction personnel use a suitable tool, such as a wrench, to clamp the adjusting rod 136 and rotate it clockwise. Since the thread direction of the first movable rod 134 is opposite to that of the second movable rod 135, when the adjusting rod 136 rotates, it will drive the first movable rod 134 and the second movable rod 135 to make relative expansion movements, thereby pushing the two adjacent support plates 11 to rotate around the pin, thus increasing the included angle. Conversely, to decrease the included angle, the construction personnel rotate the adjusting rod 136 counterclockwise, causing the first movable rod 134 and the second movable rod 135 to make relative contraction movements, thus decreasing the included angle of the support plates 11. The construction personnel repeatedly rotate the adjusting rod 136 and use measuring tools to measure the included angle in real time until the included angle of the adjacent support plates 11 is adjusted to the angle that meets the design requirements.

[0037] In terms of ease of adjustment, the angle between adjacent support plates 11 can be changed simply by rotating the adjusting rod 136. No multiple people or complex tooling are required; a single person on site can easily complete the adjustment using ordinary hand tools. This simple operation improves efficiency and effectively saves manpower and time costs. Regarding adjustment precision, the inherent precision of the threaded connection provides a basis for fine control of angle adjustment. Operators can precisely control the rotation of the adjusting rod 136 according to the minute angle changes specified in the design drawings, keeping angle errors within a minimal range. This effectively ensures high precision after chamfering and reduces repairs and rework due to angle deviations.

[0038] like Figure 3 As shown, in a preferred embodiment, the support plate 11 is provided with a plurality of through holes 111, and the support plate 11 is provided with a movable cover plate 112 at the through holes 111. The first side of the movable cover plate 112 is hinged to the support plate 11, and the second side of the movable cover plate 112 is connected to the support plate 11 by a movable pin 113.

[0039] To perform grouting, the operator moves the movable pin 113, then opens the movable cover plate 112, exposing the through hole 111. Next, the grouting pipe is inserted into the through hole 111, and the grouting equipment is turned on, allowing concrete grout to be injected into the chamfered formwork 100 through the through hole 111, ensuring the concrete is densely packed. When vibration is required, the movable cover plate 112 is opened again, the vibrator is inserted through the through hole 111, and the vibration equipment is turned on to vibrate the injected concrete, improving the quality of the concrete pouring. After the operation is completed, the movable cover plate 112 is closed, and the movable pin 113 is inserted to lock the movable cover plate 112.

[0040] From the perspective of improving construction quality, direct grouting and vibration through the through-holes 111, compared to the traditional method of working only from the top of the formwork, allows the concrete to fill the corners of the chamfer more evenly and deeply, reducing the risk of voids and incomplete compaction in the concrete and improving the pouring quality of the chamfered concrete. In terms of construction efficiency, multiple through-holes 111 can be used for grouting or vibration simultaneously, eliminating the need to wait for the concrete to slowly flow to various parts, thus accelerating the construction process and saving time. Furthermore, the design of the movable cover plate 112 facilitates operation and allows the through-holes 111 to be closed when not in use, ensuring the integrity of the model surface and guaranteeing the quality of the finished product.

[0041] like Figure 2 As shown, in a preferred embodiment, the connecting surface of the support plate 11 is provided with stiffeners 114, which include transverse stiffeners 115 and longitudinal stiffeners 116.

[0042] A third connecting hole 117 is provided on the rib plate 114 at the edge of the support plate 11. A fastener is provided in the third connecting hole 117 for connecting two adjacent chamfer templates 100.

[0043] When fabricating the chamfered template 100, the transverse stiffeners 115 and longitudinal stiffeners 116 are welded to the connecting surface of the support plate 11 to enhance the structural strength of the support plate 11. When splicing adjacent chamfered templates 100, the third connecting hole 117 on the edge stiffener 114 of one template is aligned with the corresponding position of the other template, bolts and other fasteners are inserted and tightened to ensure a tight connection between adjacent chamfered templates 100, ensuring the stability of the entire chamfered template 100 system and laying a solid foundation for subsequent construction.

[0044] The stiffening rib 114 enhances the load-bearing capacity of the support plate 11, resists the pressure during concrete pouring, reduces the risk of deformation, and ensures the quality of chamfering. The design of the third connecting hole 117 and the fasteners makes it convenient and secure to splice adjacent chamfering templates 100, improves construction efficiency, and reduces the probability of quality problems caused by loose template splicing.

[0045] like Figure 1 and Figure 2As shown, in a preferred embodiment, tie rods 14 are provided on the two support plates 11, and a protective tube 141 is sleeved between the two support plates 11 on the tie rods 14.

[0046] The vertically arranged support plate 11 is provided with a diagonal brace 19 on its connecting surface. The first end of the diagonal brace 19 abuts against the support plate 11, and the second end of the diagonal brace 19 is connected to the steel cage 200.

[0047] After the initial installation of the support plates 11 is completed, the tie rods 14 are installed. First, the protective tube 141 is placed between the two support plates 11, in the middle of the tie rod 14. Then, the tie rod 14 is passed through the corresponding mounting holes on the two support plates 11. At this point, the protective tube 141 is fitted onto the tie rod 14. Nuts are then tightened on the outside of the support plates 11 to secure the tie rod 14. The tension of the tie rod 14 is achieved by adjusting the nuts. This prevents the tie rod 14 from directly contacting the concrete. For the vertical support plates 11, the first end of the diagonal brace 19 is tightly abutted against its connecting surface. A suitable angle is found, and the second end of the diagonal brace 19 is welded or fixed to the reinforcing cage 200 using connectors, ensuring the diagonal brace 19 provides stable support. In this way, the tie rods 14 and diagonal braces 19 work together to further improve the stability of the chamfered formwork 100 system.

[0048] The combination of tie rod 14 and protective tube 141 serves two purposes: firstly, the tension of tie rod 14 effectively resists the lateral thrust generated during concrete pouring, preventing displacement and deformation of the support plate 11 and ensuring accurate chamfer dimensions; secondly, the protective tube 141 prevents tie rod 14 from being encased in concrete, facilitating disassembly of tie rod 14 and preventing corrosion from concrete encapsulation, thus extending its service life. The diagonal brace 19 provides reliable lateral support for the vertical support plate 11, enhancing structural stability, reducing the risk of formwork collapse, and ensuring construction safety and quality.

[0049] like Figure 3 As shown, in a preferred embodiment, the support plate 11 is provided with a positioning hole 118, a first positioning bar 15 connected to the reinforcing cage 200 is provided in the positioning hole 118, a second positioning bar 16 connected to the reinforcing cage 200 is provided outside the support plate 11, and a positioning connecting bar 17 is provided between the first positioning bar 15 and the second positioning bar 16.

[0050] A wedge-shaped piece 18 is provided between the positioning connecting rib 17 and the support plate 11.

[0051] When preparing to fix the relative position of the support plate 11 and the reinforcing cage 200, first insert the first positioning rib 15 into the positioning hole 118 of the support plate 11, and weld one end of it to the reinforcing cage 200. Then, weld the second positioning rib 16 to the reinforcing cage 200 on the outside of the support plate 11. Then, connect the positioning connecting rib 17 to the first positioning rib 15 or the second positioning rib 16 by welding or special connectors. The first positioning rib 15 can connect to multiple second positioning ribs 16, and the second positioning rib 16 can also connect to multiple first positioning ribs 15, so as to form a stable positioning frame. At this time, insert the wedge 18 into the gap between the positioning connecting rib 17 and the support plate 11, and tap the wedge 18 to make it wedge tightly, further tightening the connection, and the support plate 11 is stably positioned in the preset position of the reinforcing cage 200.

[0052] In this embodiment, the positioning structure ensures the positional accuracy between the support plate 11 and the reinforcing cage 200, preventing the support plate 11 from shifting or shaking during concrete pouring, ensuring the accuracy of the chamfering template 100 installation, and thus improving the chamfering quality. The stable frame formed by the first positioning rib 15, the second positioning rib 16, and the positioning connecting rib 17, together with the fastening effect of the wedge-shaped member 18, enhances the anti-interference ability of the support plate 11 under complex construction conditions, reduces pouring defects caused by template displacement, improves construction efficiency, and reduces the risk of rework.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
