Description

Technical Field

[0001] This utility model relates to the field of caisson lowering plate technology, specifically to a support device. Background Technology

[0002] In bathrooms and other areas of building construction where drainage is required, a recessed slab system is typically used for floor construction. During formwork installation, the recessed slab on the inner side of the beam requires lateral support. This support often consists of a rod with one end resting on the beam side of the recessed slab, and the other end supported by a steel rebar on the bottom surface of the recessed slab. After the concrete hardens, the rebar ends are cut off from the bottom surface of the slab. However, in areas with water, such as bathrooms, the embedded rebar ends will gradually corrode over time, creating a leak point and causing water leakage. Furthermore, it is necessary to find additional steel pipes or rebar of suitable length for support, making construction cumbersome and wasteful of materials. Utility Model Content

[0003] In view of this, the present invention provides a support device to solve the problems of existing support methods being troublesome to construct, wasteful of materials, and prone to leakage.

[0004] In a first aspect, this utility model provides a support device, comprising:

[0006] The first connecting component has one end connected to the first connecting end and the other end connected to the pull screw of the lowering plate on one side of the support rod;

[0007] The second connecting component has one end connected to the second connecting end and the other end connected to the tie rod of the lowering plate on the other side of the support rod.

[0008] Beneficial Effects: The support rod of the support device is connected to the first connecting assembly via a first connecting end, and to the second connecting assembly via a second connecting end. The first and second connecting assemblies are then connected to the tie rods of the lowered plates on both sides of the support rod, thus providing support for the lowered plates on both sides. The first and second connecting assemblies, connected to the tie rods, together with the support rod, form an integrated support device. The tie rods and the beam-side formwork of the lowered plate can directly support the support device vertically, allowing the support device within the lowered plate to be suspended, eliminating the need for stirrup reinforcement or spacers below, and preventing leakage points in the lowered plate. It also avoids the need for additional materials to support the support device. When the first connecting end of the support rod connects to the second connecting end of another support rod, several support rods can be connected along their length to support a pair of lowered plates on both sides. Furthermore, when the first connecting end connects to the body of another vertically positioned support rod, it can simultaneously support a pair of lowered plates on both sides in the opposite direction, thus providing support for each lowered plate of the caisson in the lowered plate system.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] The following is combined Figures 1 to 2 This describes an embodiment of the support device of the present invention.

[0037] According to an embodiment of the present invention, a support device is provided, comprising a plurality of support rods 1, a first connecting assembly 2, and a second connecting assembly 3. Each support rod 1 includes a rod body 11, a first connecting end 12, and a second connecting end 13. One end of the rod body 11 is the first connecting end 12, and the other end is the second connecting end 13. The first connecting end 12 is adapted to connect to the second connecting end 13 of another support rod 1, or to connect to the rod body 11 of another support rod 1. One end of the first connecting assembly 2 is connected to the first connecting end 12, and the other end is connected to a tie rod 100 of a lowering plate on one side of the support rod 1. One end of the second connecting assembly 3 is connected to the second connecting end 13, and the other end is connected to a tie rod 100 of a lowering plate on the other side of the support rod 1.

[0038] The support rod 1 of the support device provided in this embodiment is connected to the first connecting component 2 via the first connecting end 12 and to the second connecting component 3 via the second connecting end 13. The first connecting component 2 and the second connecting component 3 are respectively connected to the tie rods 100 of the lowered plates on both sides of the support rod 1, thereby providing support for the lowered plates on both sides. The first connecting component 2 and the second connecting component 3 are connected to the tie rods 100, forming an integral support device with the support rod 1. The tie rods 100 and the beam-side formwork of the lowered plate can directly support the support device in the vertical direction, allowing the support device inside the lowered plate to be suspended in the air. No stirrup reinforcement or spacers are needed below, avoiding leakage points in the lowered plate. It also avoids the need for additional materials to support the support device. When the first connecting end 12 of support rod 1 is connected to the second connecting end 13 of another support rod 1, several support rods 1 can be connected along their own length direction, thereby supporting a pair of lowered plates on both sides. Furthermore, when the first connecting end 12 is connected to the rod body 11 of another vertically arranged support rod 1, it can simultaneously support a pair of lowered plates on both sides in the other direction, thus providing support for each lowered plate of the caisson in the lowered plate system. The support device has a simple construction method. This support device forms an integral unit with the existing tie rods 100 of the beam formwork. The tie rods 100 and the beam side formwork of the lowered plate can directly support the support device in the vertical direction, allowing the support device inside the lowered plate to be suspended in the air. No stirrups or pads are needed below, avoiding leakage points in the lowered plate. Moreover, the support rods 1 can be combined very flexibly and freely to support the formwork in all directions of the caisson lowered plate, providing good support effect.

[0039] It should be noted that when using the caisson lowering method for construction, the lowered slabs are usually only arranged in two ways: parallel or perpendicular. Therefore, several support rods 1 can be connected along the first direction to support the formwork on both sides of the first direction, or several support rods 1 can be connected along the second direction perpendicular to the first direction to support the formwork on both sides of the second direction, thus creating two completely independent support systems. Alternatively, the support rods 1 in the second direction can be connected with the support rods 1 in the first direction to create a combined support system. The specific connection method of the support rods 1 is not limited here and should be set according to the needs of on-site construction.
