Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically to a formwork support structure for large-span sloping roofs. Background Technology

[0002] In the construction of large-span sloping roofs, traditional formwork support systems generally use full-span scaffolding on the ground as a foundation, constructing a vertical support network through uprights, horizontal bars, and diagonal braces. However, in practical applications, this technology encounters the problem of excessive ground space occupation, resulting in a reduced range of movement for construction workers and hindering construction. Therefore, a new formwork support structure for large-span sloping roofs was designed. Utility Model Content

The abutment assembly includes a first abutment rod rotatably connected to the lifting platform and a second abutment rod fixedly connected to the lifting platform. The first abutment rod and the second abutment rod are arranged in the same row. The first abutment rod is inclined and supported at the bottom of the formwork by the downward pressure of the second abutment rod.

[0005] As a further improvement of this utility model, the second abutment rod includes a fixing part and an adjusting part. One side of the adjusting part is threadedly connected to the fixing part, and the other side is a ball head. The first abutment rod is provided with a guide groove for the adjusting part to extend into, and the guide groove extends along the axial direction of the first abutment rod.

[0006] As a further improvement of this utility model, the base includes a first mounting part and a second mounting part. The end faces of the first mounting part and the second mounting part that abut against each other are provided with intersecting concave and convex surfaces. The concave and convex surfaces are in a concave-convex fit. The first mounting part and the second mounting part are provided with locking members for fixed connection.

[0007] As a further improvement of this utility model, the base is provided with side plates on both sides corresponding to the jack, and the side plates are provided with through grooves.

[0014] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0015] Reference Figure 1-3 As shown, a large-span sloping roof formwork support structure includes a cantilever beam 1 and a support assembly installed on the cantilever beam 1 to support the bottom of the sloping roof formwork. The support assembly includes a base, a lifting assembly, and an abutment assembly. The base is fixedly connected to the cantilever beam 1. The lifting assembly is installed on the base and can move towards the formwork. The lifting assembly includes a jack 7 fixedly connected to the base and a lifting platform 5 set on top of the jack 7. The abutment assembly includes a first abutment rod 8 rotatably connected to the lifting platform 5 and a second abutment rod 9 fixedly connected to the lifting platform 5. The first abutment rod 8 and the second abutment rod 9 are arranged in the same row. The first abutment rod 8 is inclined and supported at the bottom of the formwork by the second abutment rod 9.

[0016] In this embodiment, the support assembly is set on the cantilever beam 1, which reduces the space occupied on the ground compared to scaffolding, giving workers more room to move around and improving efficiency. To better adapt the base to the structure of the cantilever beam 1, the base is installed around the cantilever beam 1, which is more suitable for the cantilever beam 1 and makes better use of space. The lifting assembly can be used to adjust the height of the abutment assembly. By adjusting the jack 7, the lifting platform 5 is raised, and the abutment assembly is also raised with the lifting platform 5, thus abutting against the bottom plate of the template and supporting the bottom of the template. The jack 7 is easy to operate, making it convenient for workers to adjust the lifting platform 5 to the appropriate position to cooperate with the abutment assembly to support the bottom of the template. The first abutment rod 8 and the second abutment rod 9 are set in the same row. This arrangement allows the second abutment rod 9 to better limit the first abutment rod 8, so that the first abutment rod 8 can more stably support the bottom of the template.

[0017] Preferably, the second abutting rod 9 includes a fixing part and an adjusting part. One side of the adjusting part is threaded to the fixing part, and the other side is a ball head. The first abutting rod 8 is provided with a guide groove for the adjusting part to extend into. The guide groove extends along the axial direction of the first abutting rod 8.

[0018] In this embodiment, the threaded connection between the adjusting part and the fixing part allows for adjustment of the overall length of the second abutting rod 9, and the threaded connection also provides strong connection strength. The side of the adjusting part away from the fixing part is set as a ball head, which has the advantage of being more flexible and able to better cooperate with the first abutting rod 8. The ball head of the adjusting part is deeply inserted into the guide groove, and the shape of the guide groove is adapted to the ball head, which can increase the contact area and improve the friction. By adjusting the length of the second abutting rod 9, the first abutting rod 8 is pushed to abut against the bottom of the template, and the ball head is inserted into the groove of the first abutting rod 8, which can strengthen the support between the first abutting rod 8 and the bottom of the template.

[0019] Preferably, the base includes a first mounting part 2 and a second mounting part 3. The end faces of the first mounting part 2 and the second mounting part 3 that are used for abutting are provided with intersecting concave and convex surfaces, and the concave and convex surfaces are in a concave-convex fit. The first mounting part 2 and the second mounting part 3 are provided with locking members 11 for fixed connection.

[0020] In this embodiment, the first mounting part 2 and the second mounting part 3, when combined, can surround the suspension beam 1 and be fixedly connected to the suspension beam 1. The surfaces of the first mounting part 2 and the second mounting part 3 that abut against each other are provided with intersecting concave and convex surfaces. The dimensions of the concave and convex surfaces are matched to allow for a concave-convex fit. This arrangement increases the contact area between the first mounting part 2 and the second mounting part 3, thereby increasing the friction. The locking member 11 is a bolt that passes through the position where the concave and convex surfaces of the first mounting part 2 and the second mounting part 3 fit together, preventing the first mounting part 2 and the second mounting part 3 from falling off the suspension beam 1 and increasing stability.

[0021] Preferably, the base is provided with side plates 4 on both sides of the jack 7, and the side plates 4 are provided with through grooves. The lifting platform 5 is fixedly connected to both sides with sliders 6, and the sliders 6 are set in the through grooves.

[0022] In this embodiment, the lifting platform 5 moves on the side plate 4 via the slider 6. The slider 6 can make the lifting platform 5 slide smoothly and can also limit the lifting platform 5 so that it will not come off the side plate 4.

[0023] Preferably, the side plate 4 is provided with a through hole 10 for the screw to extend into on the side corresponding to the adjustment of the jack 7.

[0024] In this embodiment, the operator can adjust the jack 7 by inserting the through hole 10, which facilitates operation and improves work efficiency.

[0025] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
