Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, in particular to a support tool for an I-beam cantilevered steel bar truss floor deck. Background Art

[0002] At present, the floor construction support system in building construction mainly uses scaffolding tubes as a way to support the formwork. The advantages of scaffolding tubes as a support system are good support stability and high safety.

Furthermore, the tripod's length cannot meet the requirements of supporting slabs of varying sizes. Furthermore, the tripod is inconvenient to store and takes up considerable storage and transportation space. Utility Model Content

The size of the closed structure satisfies that: the disassembled diagonal telescopic mechanism can be accommodated in the closed structure.

[0033] Example 2

[0034] like Figure 2-4 As shown, the vertical telescopic mechanism includes a vertical slide 3 and a vertical slide 4. The vertical slide 3 is a U-shaped structure with an open end facing inward. The bottom of the U-shaped structure is slidably connected to the vertical slide 4. The lower part of the inner wall of the U-shaped structure is provided with a first guide groove 31 along the length direction.

The first locking block is flush with the top of the vertical slide 4, and the U-shaped structure above the vertical slide 4 constitutes a first storage space 33.

[0036] In this embodiment, when in use, the first telescopic mechanism is adjusted by loosening the first butterfly nut to disengage the first locking block from the first positioning slot. The vertical slide is then pulled up and down to adjust the length of the first telescopic mechanism. Once the preset length is reached, the first locking block is locked into the corresponding first positioning slot, and the first butterfly nut is tightened. The first guide slot, first slide, first guide block, and first strip slot are provided to provide greater structural stability for the first telescopic mechanism. The support plate contacts the upper surface of the lower flange of the steel beam, acting as a footrest.

[0037] Example 3

[0038] like Figure 5-7 As shown, the horizontal telescopic mechanism includes a horizontal slide 1 and a horizontal slide 2. The cross-section of the horizontal slide 1 is an H-shaped structure, including left and right opposite vertical plates 12, and a horizontal plate 13 connected between the middle parts of the two vertical plates 12. The horizontal slide 2 is slidably connected between the two vertical plates 12 above the horizontal plate 13, and the upper end surface of the horizontal slide 2 is coplanar with the top of the vertical plate 12. Figure 9 As shown, the purpose of such design is to facilitate the support of the upper pad 03; one end of the horizontal chute 1 is provided with a first hinge seat 11, the first hinge seat 11 is used in conjunction with the first hinge shaft 5, and the second storage space is formed between the two vertical plates 12 where the inner side of the horizontal plate 13 is located (such as Figure 6 shown, not marked in the figure).

The top end of the second threaded rod is fixedly connected to the bottom end of the second locking block 131, and the two ends of the second locking block are respectively clamped in the second positioning grooves 24 on both sides. The second threaded rod passes through the second through hole and is screwed with a second butterfly nut 132 at the end. The second butterfly nut 132 is used to lock the horizontal slide 1 and the horizontal slide 2.

[0041] like Figure 7As shown, the first hinge seat 11 is a structure protruding downwards at one end of the horizontal chute 1.

[0042] In this embodiment, the length of the horizontal telescopic mechanism can be adjusted by loosening the second butterfly nut, disengaging the second locking block from the second positioning slot, and pulling the horizontal slide. Because the horizontal slide is coplanar with the top of the horizontal slide slot, it provides stable support and reduces installation difficulty. When the preset length is reached, the second locking block is engaged in the corresponding second positioning slot, and the second butterfly nut is tightened.

[0043] Example 4

The first oblique slide 82 and the second oblique slide 83 are respectively slidably connected to the two ends of the oblique slide 8. A number of first positioning holes are opened at both ends of the oblique slide 8 (which is a commonly used structure, not drawn in the figure), and a number of second positioning holes are opened on the first oblique slide 82 and the second oblique slide 83 (which is a commonly used structure, not drawn in the figure). The oblique slide 8 is fixedly connected to the first oblique slide 82 or the second oblique slide 83 by a positioning bolt 81 that passes through the first positioning hole and is screwed to the second positioning hole.

[0045] like Figure 1 As shown, the outer ends of the first oblique slide 82 and the second oblique slide 83 are respectively provided with connecting seats for connecting with the second hinge shaft 6 and the third hinge shaft 7.

[0046] In this embodiment, the length of the oblique telescopic mechanism can be adjusted by loosening the two positioning bolts 81 and inserting and removing the first oblique slide 82 and the second oblique slide 83. After the required length is reached, the positioning bolts 81 are tightened.

[0047] Example 5

[0049] As described in the above embodiment, when storing, first remove the diagonal telescopic mechanism, completely store and lock the horizontal telescopic mechanism, the vertical telescopic mechanism, and the diagonal telescopic mechanism, fold the horizontal telescopic mechanism and the vertical telescopic mechanism, and at the same time, place the diagonal telescopic mechanism between the first and second storage spaces, and then lock the connecting plates on both sides by the bolt and nut assembly.

[0050] When this new type is used, Figure 9 As shown, the support plate is brought into contact with the upper end of the lower flange plate of the I-beam 02, and the length of the horizontal telescopic mechanism is adjusted to meet the support width requirement. Then, the length of the vertical telescopic mechanism is adjusted so that the top of the horizontal slide is against the lower end of the upper flange plate of the I-beam 02. The length of the oblique telescopic mechanism is adjusted so that its two ends are hinged to the ends of the horizontal slide and the vertical slide. A pad 03 is laid between the formwork 01 and the top of the horizontal telescopic mechanism. Then, the I-beam cantilevered steel truss floor deck is cast on the formwork.
