Description

Technical Field

[0001] This utility model relates to waffle boards, and in particular to a combined internal support device for trapezoidal waffle boards. Background Technology

[0002] Waffle slabs are a type of formwork used in reinforced concrete cast-in-place grid beam floor slabs. In some electronic chip factories, cleanrooms are a crucial component. Due to process requirements, tens of thousands of pipelines need to run through the second and third floors. Maintaining positive air pressure within the cleanroom requires forcing clean air into it, resulting in numerous holes in the floor slab between the second and third floors. Waffle slabs are used to create these holes. There are two main types of waffle slabs: trapezoidal and cylindrical. The trapezoidal waffle slab has a large trapezoidal cylinder at the bottom. To ensure the structural strength and reliability of the internal structure of the trapezoidal cylinder when concrete is poured on the outside of the waffle slab, a supporting structure is installed inside the trapezoidal cylinder. This supporting structure supports the inner wall of the trapezoidal cylinder, preventing the concrete from deforming it. Existing support structures typically use wooden boards spliced ​​together to form a cross or grid-like support frame. The use of wooden boards is heavy, cumbersome to process, inconvenient to install, and increases construction costs. Furthermore, after construction, disassembling the boards is difficult, and the boards can easily damage the inner wall of the trapezoidal cylinder, affecting the smoothness of the waffle board's inner wall and thus its performance. Therefore, the applicant previously applied for Chinese Utility Model Patent 202322726847.5, entitled "Internal Support Device for Trapezoidal Waffle Board." The disadvantages of this structure are: the inner support frame is manufactured as a single piece of plastic material, resulting in a large volume. Since a large number of waffle boards and the inner support frame are needed during construction, disassembling these inner support frames after construction takes up a lot of space, which is inconvenient for storage and transportation. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a modular internal support device for trapezoidal waffle boards that is assembleable, detachable, stackable after disassembly, small in size, occupies little space, and is beneficial for packaging, warehousing and transportation.

[0004] The technical solution of the combined internal support device for a trapezoidal waffle board of this utility model is as follows: it includes a horizontal support plate and a vertical support plate made of plastic material. The lower part of the horizontal support plate has a downward-facing lower slot, and the upper part of the vertical support plate has an upward-facing upper slot. The horizontal support plate is inserted and matched with the upper slot of the vertical support plate through the lower slot.

[0005] Furthermore, there are two horizontal support plates and two vertical support plates, with two lower slots on the lower part of the horizontal support plate and two upper slots on the upper part of the vertical support plate.

[0006] Furthermore, the transverse support plate and the longitudinal support plate are respectively provided with support base plates made of plastic material at both ends.

[0007] Furthermore, a protruding U-shaped sliding plate is provided on one side of the supporting base plate. The upper part of the sliding plate has a sliding entrance, and a sliding groove is formed in the sliding plate. A baffle is provided on the front side of the sliding plate. Sliding pieces are provided at both ends of the transverse support plate and the longitudinal support plate. The sliding pieces are inserted into the sliding groove through the sliding entrance. The two sides of the sliding pieces cooperate with the sliding plate, and the inner wall of the sliding pieces cooperates with the baffle.

[0008] Furthermore, a positioning step is provided at the bottom of the slide plate, and the positioning step is positioned and engaged with the bottom of the U-shaped slide plate.

[0009] Furthermore, reinforcing ribs are provided on the transverse support plate, longitudinal support plate, and support base plate respectively.

[0010] The advantages of this utility model's combined internal support device for trapezoidal waffle slabs are as follows: 1. The support device is divided into three components: a transverse support plate, a longitudinal support plate, and a support base plate. These components are connected by interlocking, making installation and disassembly convenient. After disassembly, it is plate-shaped and can be stacked, reducing its volume and facilitating packaging, storage, and transportation. 2. The three components—the transverse support plate, the longitudinal support plate, and the support base plate—are made of plastic, making manufacturing easy and reducing costs. 3. When concrete is poured onto the exterior of the trapezoidal waffle slab, the support device, composed of the transverse support plate, the longitudinal support plate, and the support base plate, provides excellent support for the interior of the trapezoidal cylinder, preventing deformation at that location due to excessive pouring pressure and effectively ensuring the structural strength and support reliability of the trapezoidal waffle slab.
