Description

Technical Field

[0001] This utility model relates to the field of building roof construction, and in particular to a formwork support device for the eaves of a pitched roof. Background Technology

[0002] With the promotion of the Neo-Chinese architectural style, sloping concrete roofs are widely used in residential, cultural and tourism construction projects due to their aesthetic appeal and good drainage. The eaves of a sloping roof are a key connection between the roof and the walls. The precision of construction is crucial to the building's appearance and waterproofing performance. Formwork is required to support the concrete molding, and the eaves must be adapted to different overhang width requirements.

[0003] However, existing formwork technology has obvious defects: First, traditional brackets are of fixed length and have no telescopic adjustment function, which cannot be adapted to different eaves overhang widths. Various components need to be customized, which increases costs and is cumbersome to prepare. Second, in the existing formwork construction, the wooden squares need to be fixed to the brackets with nails, which is unreliable. Drilling holes will damage the bracket structure, making it impossible to reuse. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a formwork support device for the eaves of a pitched roof, which aims to improve the problem of poor length adaptability of traditional brackets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pitched roof eaves support device, used to be mounted under the main body of the roof to form an eaves forming foundation, including a base bracket, a tail bracket, a support assembly, and a movable connecting assembly. The support assembly includes full-span uprights and full-span crossbars. The movable connecting assembly includes an extension frame, a threaded hole, and a fastening bolt. The extension frame is fixed to the end of the base bracket. The tail bracket is a hollow structure. The extension frame passes through the hollow cavity of the tail bracket. The threaded hole is opened on the side of the tail bracket. The fastening bolt is threaded into the threaded hole and abuts against the extension frame. A bracket vertical stop is provided on the tail bracket. Both the base bracket and the tail bracket are erected on the support assembly.

[0006] Preferably, at least one wooden backrest is provided on the base bracket, the tail bracket, and the bracket vertical bar.

[0007] Preferably, the cross-sectional dimensions of the extension frame are adapted to and smaller than the cross-sectional dimensions of the internal cavity of the tail bracket.

[0008] Preferably, the bottom of both the base bracket and the tail bracket is provided with a limiting steel plate.

[0009] Preferably, the wooden beams are supported on the back of the wooden beams, and wooden templates for supporting the main body of the roof are laid on the wooden beams.

[0010] Preferably, the support assembly further includes an adjustable base, which is disposed below the crossbar of the full-span scaffold.

[0011] Preferably, both the base bracket and the tail bracket are mounted on the full-span uprights of the support assembly in conjunction with the limiting steel plate.

[0012] Preferably, the horizontal bar of the scaffolding is connected to the vertical bar of the scaffolding to provide horizontal fixation and auxiliary support for the vertical bar of the scaffolding.

[0013] Preferably, the adjustable base is located at the bottom of the scaffolding upright, and the height adjustment range of the adjustable base is 0-300mm, used to adjust the height of the scaffolding upright.

[0014] Preferably, the tail bracket and the bracket vertical guard are integrally formed structures and are both made of high-strength steel.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, a movable connecting assembly consisting of an extension frame, threaded holes, and fastening bolts is provided. Combined with the structural design of the foundation bracket and the tail bracket, this achieves the telescopic adjustment function of the formwork support device. The extension frame is fixed to the end of the foundation bracket and passes through the hollow cavity of the tail bracket. Its length can be flexibly adjusted according to the different overhang width requirements of the eaves of the pitched roof, effectively solving the problem that traditional formwork support devices are difficult to adapt to construction of eaves of different specifications. The threaded holes on the side of the tail bracket, when threaded with the fastening bolts, press against the extension frame, preventing relative displacement of the components after adjustment and ensuring the stability of the structure during the formwork support process.

[0017] 2. Timber can be directly and stably erected on the back of the formwork without the need for nails or other destructive fasteners to secure it to the bracket. This erection method not only makes the timber more reliably fixed, effectively avoiding the safety hazard of timber and formwork sliding down the slope during pitched roof construction, but also eliminates the need to drill holes in the bracket, preserving the structural integrity of the bracket. At the same time, the timber will not suffer irreversible damage due to nail fixing, allowing both the bracket and the timber to be reused, thus solving the defects of poor reliability and non-reusability of materials in traditional fixing methods.

[0018] 3. The uprights of the full-span scaffold serve as the main vertical support, bearing the main load; the horizontal members of the full-span scaffold serve as the horizontal connecting components, enhancing overall stability; and the adjustable base enables height adjustment. The three work together to comprehensively address the load transfer and stability requirements during construction, avoiding instability of the formwork structure due to imperfections in the support system, and providing a solid guarantee for the smooth progress of subsequent eaves formwork construction.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1, refer to Figures 1-4 A formwork support device for the eaves of a pitched roof is used to support the roof body 10 to form the eaves forming foundation. It includes a base bracket 1, a tail bracket 3, a support assembly, and a movable connecting assembly. The support assembly includes full-span uprights 11 and full-span crossbars 12. The movable connecting assembly includes an extension frame 6, threaded holes, and fastening bolts 7. The extension frame 6 is fixed to the end of the base bracket 1. The tail bracket 3 is a hollow structure. The extension frame 6 passes through the hollow cavity of the tail bracket 3 to achieve flexible length adjustment. The threaded holes are opened on the side of the tail bracket 3. The fastening bolts 7 are threaded into the threaded holes and abut against the extension frame 6 to ensure structural stability. The tail bracket 3 is provided with a bracket vertical stop 4 to provide lateral restraint. Both the base bracket 1 and the tail bracket 3 are erected on the support assembly. Through the telescopic cooperation of the extension frame 6 and the tail bracket 3, it can flexibly adapt to the outward width requirements of different pitched roof eaves without the need to customize various specifications of components. The locking method of the fastening bolts 7 and threaded holes can ensure the stability of the structure after adjustment and avoid relative displacement during construction. The bracket vertical block 4 provides lateral limit for subsequent formwork support, further enhancing the overall load-bearing capacity.

[0027] Example 2, refer to Figures 1-4Based on Embodiment 1, at least one wooden backrest 5 is provided on the base bracket 1, the tail bracket 3, and the bracket vertical support 4, providing evenly distributed and stable support points for the wooden beams. The wooden backrest 5 allows the wooden beams to fit tightly against the bracket structure, preventing displacement and slippage due to the slope during pitched roof construction, while also distributing load pressure. The cross-sectional dimensions of the extension frame 6 are adapted to and smaller than the cross-sectional dimensions of the internal cavity of the tail bracket 3, ensuring smooth insertion and extension without jamming, while controlling the gap between the two to prevent wobbling after adjustment. Limiting steel plates 2 are correspondingly provided at the bottom of both the base bracket 1 and the tail bracket 3, which fit tightly against the support components to form reliable limits. This effectively restricts the lateral displacement and longitudinal slippage of the brackets on the support structure, fundamentally solving the safety hazard of formwork devices slipping down the slope during pitched roof construction, while also increasing the contact area for more even load distribution. Timber beams 8 are erected on the timber backrest 5, serving as secondary joists to distribute the load. Wooden formwork 9, used to support the main roof structure 10, is laid on top of the timber beams 8. The three form a complete, overlapping support system that eliminates the need for complex fixing procedures, making installation convenient, reducing material damage, and ensuring the quality of concrete pouring.

[0028] The support assembly also includes an adjustable base 13, which, together with the scaffold uprights 11 and scaffold crossbars 12, forms a three-dimensional support foundation. The scaffold uprights 11 bear the main vertical load, the scaffold crossbars 12 enhance lateral stability, and the adjustable base 13 allows for precise height adjustment, providing a flat and stable installation benchmark for the formwork device. The foundation bracket 1 and the tail bracket 3 are both erected on the scaffold uprights 11 of the support assembly with the limiting steel plate 2. This mortise-and-tenon connection eliminates the need for destructive processing such as drilling or welding on the uprights. This preserves the structural integrity of the uprights 11, allowing for repeated use and reducing costs, while also enabling rapid assembly, improving construction efficiency, and ensuring direct and even load distribution. The scaffold crossbars 12 connect with the scaffold uprights 11 to provide horizontal fixation and auxiliary support, limiting horizontal displacement of the uprights through lateral bracing. The system effectively enhances the lateral displacement resistance of the uprights 11, preventing tilting and instability. It also connects adjacent uprights into a unified structure, ensuring even load distribution within the support system. An adjustable base 13 is located at the bottom of the uprights 11, with a height adjustment range of 0–300 mm, allowing for flexible height adjustment. This adaptable base accommodates varying site flatness and roof design heights, enabling quick correction of deviations through simple operation, ensuring the upright tops are level and providing a precise benchmark for formwork construction. The tail bracket 3 and bracket vertical support 4 are integrally molded structures, reducing connection points and both are made of high-strength steel to enhance mechanical strength. The integral design prevents loosening and detachment, while the high-strength steel enhances resistance to deformation, allowing them to withstand greater construction loads.

[0029] The construction process for the eaves of a pitched roof is as follows: First, draw the starting and ending points of the roof, clarify the position information of the full-span scaffold uprights 11 and full-span scaffold horizontal bars 12, and the required material quantities for the formwork support device, including the foundation bracket 1, tail bracket 3, extension bracket 6, fastening bolts 7, timber backrest 5, bracket vertical bars 4, and limiting steel plates 2, and prepare a material list for the formwork support device; then, prepare the materials according to the material list, process the required number of formwork support devices, and bring in the corresponding lengths of full-span scaffold uprights 11 and full-span scaffold horizontal bars 12; subsequently, proceed in the correct order. Erect the full-span scaffolding uprights 11, and use the adjustable base 13 to adjust the top full-span scaffolding crossbars 12 to the required height. Install the formwork support device and lock it in place with the fastening bolts 7. Then, lay the wooden beams 8 on the wooden backrest 5 of the formwork support device, nail the wooden templates 9, tie the reinforcing bars, and pour the concrete of the roof main body 10 for curing. After the concrete of the roof main body 10 reaches the design strength, loosen the top full-span scaffolding uprights 11, and store the formwork support device, including the foundation bracket 1 and the tail bracket 3, or reuse it for other roof construction.

[0030] Working principle: The adjustable base 13 in the support assembly is installed at the bottom of the full-span scaffold upright 11. Its height adjustment range is 0-300mm. By adjusting the adjustable base 13, the height of the full-span scaffold upright 11 can be precisely controlled, ensuring the levelness and stability of the subsequent support structure. The full-span scaffold crossbar 12 is connected to the full-span scaffold upright 11, which not only fixes the full-span scaffold upright 11 horizontally, but also provides auxiliary support, further improving the load-bearing capacity of the entire support system. The tail bracket 3 is erected on the full-span scaffold upright 11 of the support assembly. The end of the base bracket 1 is fixed with an extension bracket 6. Since the cross-sectional dimensions of the extension bracket 6 are adapted and smaller than the cross-sectional dimensions of the internal cavity of the tail bracket 3, the extension bracket 6 can be smoothly inserted into the hollow cavity of the tail bracket 3 and achieve telescopic adjustment, thereby adapting to the overhang width requirements of different pitched roof eaves. After the extension frame 6 is adjusted to the required length, the fastening bolt 7 is threaded into the threaded hole on the side of the tail bracket 3 and tightened continuously until the end of the fastening bolt 7 firmly abuts against the extension frame 6, thus completing the relative fixation of the base bracket 1 and the tail bracket 3. At the same time, the bottom of both the base bracket 1 and the tail bracket 3 is provided with limit steel plates 2, which can effectively limit the displacement of the bracket on the full-span scaffold uprights 11. The tail bracket 3 and the bracket vertical guard 4 are integrally formed structures made of high-strength steel, ensuring the rigidity and load-bearing stability of the overall bracket structure and preventing deformation during construction.

[0031] Subsequently, the formwork support structure is constructed. At least one wooden backrest 5 is installed on each of the base bracket 1, the tail bracket 3, and the bracket vertical support 4. The wooden backrest 5 provides a stable supporting surface for the wooden beams 8, allowing them to be smoothly placed on the backrests. Multiple wooden beams 8 provide a uniformly stressed foundation for the subsequent laying of the wooden formwork 9. Next, the wooden formwork 9 is laid flat on the wooden beams 8. As the forming surface that directly supports the main roof structure 10, the quality of its laying directly affects the concrete forming effect of the pitched roof eaves. Through the orderly assembly and coordination of the above components, a complete formwork support system is formed, from the support system to bracket adjustment and formwork laying. This ensures the reliability of the formwork structure and allows for flexible adaptation to the construction of pitched roof eaves of different specifications. Furthermore, during subsequent dismantling, the fastening bolts 7 can be loosened to retract the extension frame 6, facilitating the storage and reuse of the formwork device.
