[0002] A square waffle tube is a cylindrical frame structure consisting of thick-walled end caps and a cylindrical body, used to provide compressive strength. This structure is typically made of wood, steel, aluminum, iron, or other materials. Square waffle tubes are used as structural units in the field of building formwork, primarily for floor slab construction requiring high cleanliness and vibration damping.

[0003] A search revealed CN107700834B, which discloses an internal support structure for a square waffle tube. The structure includes a top baffle unit, four side wall baffle units, and a central support unit. The top baffle unit and the four side wall baffle units are respectively attached to the top and four side walls of the waffle tube's inner wall. The central support unit is located in the center of the waffle tube's inner cavity, supporting the top baffle unit and the four side wall baffle units. The central support unit includes two support plates with a notch along their symmetrical center line. The length of the notch is half the height of the support plate. The two support plates are interlocked in a cross shape. This invention provides an internal support structure for a square waffle tube that is economical, easy to construct, and lightweight, effectively solving problems such as bulging, deformation, and scratches in square waffle tubes.

[0004] However, when the above-mentioned device is in use, an intermediate support unit is installed inside the waffle tube. The intermediate support unit does not have any fixing structure on the outside. After long-term use, the internal intermediate support unit will become loose, and in severe cases, it may even fall off, resulting in poor stability. Utility Model Content

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0032] Please see Figure 1-5 As shown, this embodiment is an internal support structure for a square waffle tube, including:

[0033] Waffle cylinder 11;

[0034] The supporting component includes a supporting inner frame 21, a vertical plate 22, a pin plate 23, a limiting plate 24, an inner groove 25, a first supporting block 26, a second supporting block 27, and a groove 28. The supporting inner frame 21 is connected to the inner surface of the waffle cylinder 11 in a cross shape. The first supporting block 26 and the second supporting block 27 are connected to the four ends of the inner surface of the waffle cylinder 11. The pin plate 23 is connected through the interior of the first supporting block 26. The four ends of the top of the supporting inner frame 21 are provided with inner grooves 25, and the pin plate 23 is embedded in the interior of the inner grooves 25.

[0035] The inner support frame 21 is installed inside the waffle cylinder 11, and the upright plate 22 is clamped on both sides of the inner support frame 21 to limit the inner support frame 21. Then, the pin plate 23 is pushed so that the pin plate 23 is embedded in the inner groove 25, and one end of the pin plate 23 is engaged in the groove 28, thereby fixing the installed inner support frame 21.

[0036] The second support block 27 has a groove 28 inside. One end of the pin plate 23 is inserted into the groove 28 and connected to the inside of the groove 28. The other end of the pin plate 23 is connected to the limiting plate 24. The limiting plate 24 is attached to the outside of the first support block 26.

[0037] When the pin plate 23 is pushed into the interior of the groove 25, the limiting plate 24 will fit against the outside of the first support block 26 to prevent the pin plate 23 from slipping out, thus achieving the limiting effect.

[0038] The four ends of the inner surface of the waffle cylinder 11 are symmetrically connected with vertical plates 22, which are clamped and connected to both sides of the outer surface of the supporting inner frame 21.

[0039] After the inner support frame 21 is installed inside the waffle cylinder 11, the upright plate 22 is simultaneously clamped on both sides of the inner support frame 21, which serves as a limiting function.

[0040] It also includes a fixing component, which includes a first slot 31, a second slot 32 and a plug 33. The second slot 32 is provided on one side of the first support block 26, the first slot 31 is provided on one side of the second support block 27, and the plug 33 is connected to one side of the pin plate 23.

[0041] When the pin plate 23 is pulled out, the insert block 33 will be fixed inside the first pin. When the pin plate 23 is embedded inside the inner groove 25, the insert block 33 will be fixed inside the second slot 32 to position the pin plate 23.

[0042] The working principle is as follows: First, the inner support frame 21 is installed inside the waffle cylinder 11, and the upright plate 22 clamps on both sides of the inner support frame 21 to limit its position. Then, the pin plate 23 is pushed so that it is embedded in the inner groove 25. The insert block 33 is fixed inside the second slot 32, and one end of the pin plate 23 is engaged inside the groove 28, thereby fixing the installed inner support frame 21. After long-term use, this prevents the inner support frame 21 from loosening or even falling off in severe cases, thus improving the stability of the waffle cylinder 11 during use. When disassembling, the pin plate 23 is pulled out, so that one end of the pin plate 23 separates from the groove 28 and the inner groove 25. The insert block 33 is fixed inside the first slot 31, allowing the inner support frame 21 to be removed for replacement or maintenance.

[0043] Please see Figure 1 , Figure 2 , Figure 5 As shown, this embodiment is based on the above embodiment 1, and further includes a reinforcing component.

The top of the supporting inner frame 21 is connected to the pressure strip 42, and the pressure strip 42 is attached to the top of the supporting inner liner 41.

[0044] The inner support liner 41 is installed inside the waffle cylinder 11. After the inner support frame 21 is installed inside the waffle cylinder 11, the tower will fit against the top of the inner support liner 41, preventing the waffle cylinder 11 from deforming after long-term use.

[0045] It also includes reinforcing components, which include a supporting inner liner 41, a pressure strip 42, a positioning groove 43, and a positioning block 44. The supporting inner liner 41 is connected to the four corners of the inner surface of the waffle cylinder 11, and the top of the supporting inner frame 21 is connected to the pressure strip 42, which is attached to the top of the supporting inner liner 41.

[0046] After the pressure strip 42 is attached to the top of the supporting inner liner 41, the positioning block 44 will be inserted into the positioning groove 43 for fixation.

[0047] The working principle is as follows: First, the inner support liner 41 is installed inside the waffle cylinder 11. After the inner support frame 21 is installed inside the waffle cylinder 11, the tower will fit against the top of the inner support liner 41, while the positioning block 44 is fixed inside the positioning groove 43 to fix the inner support liner 41 after installation. The inner support liner 41 provides support for the corners of the waffle cylinder 11, preventing deformation of the waffle cylinder 11 after long-term use.
