[0002] At present, with the large-scale promotion of prefabricated buildings, especially steel structure buildings, steel truss floor decking (hereinafter referred to as "floor decking") is widely used in the field of public buildings. Compared with cast-in-place floor slabs and composite slabs, floor decking has better integrity and easier construction.
[0003] During the construction of the main structure, there are often reserved holes for temporary construction facilities such as water and fire protection pipe holes and temporary power cable holes. There are secondary hanging hole construction tasks in each structural layer. The traditional hanging hole method uses iron wire to fix the wooden formwork through the steel bars placed horizontally at the hole, which has the following problems:
[0004] 1. The quality of the entire construction is determined by the workers' proficiency level, and the quality is difficult to control;
[0005] 2. The wire hanging hole cannot be removed after completion, forming a leakage point and easy to rust;
[0006] 3. The combination of the hanging hole template and the original structure is not tight, which is easy to leak slurry, resulting in the loose combination of the hanging hole structure and the original main structure, and the poor quality of the edge appearance;
[0007] The above problems become more prominent due to the high degree of customization of the floor decking, the composite truss steel bars and the M-shaped galvanized steel skin at the bottom, which makes it more difficult to combine with the wooden formwork. Utility Model Content

[0036] like Figure 1-Figure 2 The steel bar truss floor deck hanging hole device shown in the figure comprises a mounting rod 1, a horizontal adjustment member 2, a connecting sleeve 3 and a blocking plate 5. The mounting rod 1 is arranged along the horizontal adjustment member 2, a connecting sleeve 3 and a blocking plate 5. Figure 1The directions shown are distributed on the top of the blocking plate 5 on the left and right sides. The mounting rod 1 is provided with scale markings in the length direction. Two groups of mounting rods 1 are provided and are respectively located on the front two sides of the blocking plate 5. A horizontal adjustment piece 2 is provided on each group of mounting rods 1. The horizontal adjustment piece 2 is sleeved on the outside of the mounting rod 1 and can slide along the length direction of the mounting rod 1. A limiting device is provided between the horizontal adjustment piece 2 and the mounting rod 1 for fixing the position of the horizontal adjustment piece 2 in the length direction of the mounting rod 1. The connecting sleeve 3 is fixedly connected to the bottom of the horizontal adjustment piece 2. A height adjustment device is provided between the connecting sleeve 3 and the blocking plate 5 for adjusting the height spacing between the blocking plate 5 and the connecting sleeve 3.
[0037] Specifically, Figure 3 and Figure 4 As shown, the limiting device includes a limiting tooth 6 and a connecting tooth 7 that are engaged with each other. The limiting tooth 6 is arranged at the upper end of the outer wall of the mounting rod 1 and is distributed along the length direction of the mounting rod 1. The lower end surface of the mounting rod 1 is a smooth surface. The horizontal adjustment member 2 is a cylindrical shell with openings at both ends. The connecting tooth 7 is arranged at the upper end of the inner wall of the horizontal adjustment member 2. The lower end of the inner wall of the horizontal adjustment member 2 is a smooth surface. When the mounting rod 1 and the horizontal adjustment member 2 are engaged with the limiting tooth 6 and the connecting tooth 7, as shown in FIG. Figure 4 As shown, a gap is provided between the lower end surface of the inner wall of the mounting rod 1 and the lower end surface of the inner wall of the horizontal adjustment member 2, and the gap is larger than the tooth height of the limiting tooth 6. By setting the gap, the horizontal adjustment member 2 can be lifted upward, thereby separating the limiting tooth 6 and the connecting tooth 7, so as to realize the adjustment of the position of the horizontal adjustment member 2 in the length direction of the mounting rod 1.
[0038] like Figure 3 As shown, the height adjustment device includes an adjustment screw 4 and a sliding sleeve 13. The connecting sleeve 3 is hollow inside, open at the lower end, and the inner wall is provided with internal threads distributed along the height direction. The sliding sleeve 13 is slidably connected to the lower side of the connecting sleeve 3, as shown in FIG. Figure 5 As shown, two groups of installation positions with different positions are provided on the blocking plate 5, and each group includes four installation holes 8 with installation positions distributed in a rectangular shape. By setting two groups of installation positions, it can be used to connect blocking plates 5 of different sizes, so as to adapt to the blocking of reserved holes 14 of different sizes. The end of the screw rod away from the head of the adjusting bolt 4 passes through the blocking plate 5 from bottom to top and is threadedly connected with the connecting sleeve 3, and the blocking plate 5 is provided with a mounting hole 8, and the diameter of the mounting hole 8 is larger than the outer diameter of the screw rod of the adjusting bolt 4 and smaller than the outer diameter of the head of the adjusting bolt 4; by adjusting the threaded connection between the screw 4 and the connecting sleeve 3, the distance between the blocking plate 5 and the mounting rod 1 in the height direction can be adjusted, as shown in FIG. Figure 6 and Figure 7As shown, the sliding sleeve 13 is slidably connected up and down at the position below the connecting sleeve 3. Through the setting of the sliding sleeve 13, the distance between the bottom mold steel plate 12 and the upper chord steel bar 9 of different heights can be adaptively adjusted, thereby ensuring that the lower end of the sliding sleeve 13 is in close contact with the bottom mold steel plate 12, thereby protecting the lower end opening of the connecting sleeve 3 and the adjusting bolt 4 and its mounting hole, avoiding the problem of concrete entering the connecting sleeve 3 or causing the adjusting bolt 4 to be unable to connect with the connecting sleeve 3 during floor pouring. In addition, the sliding sleeve 13 is made of transparent material, which can facilitate observation of whether concrete or other impurities have entered the interior.
[0039] Before pouring the floor slab concrete, after determining the location and size of the reserved opening 14, prepare two installation rods 1, and each installation rod 1 is provided with a set of horizontal adjustment parts 2 at both ends. The installation rod 1 is horizontally arranged and tied above the upper chord steel bar 9 of the floor slab truss steel bar, and the lower end of the sliding sleeve 13 contacts the upper end surface of the bottom mold steel plate 12, and then the concrete is poured; before the secondary hanging hole, first find the position of the sliding sleeve 13 and the connecting sleeve 3, clean the concrete around the reserved opening 14 and roughen the reserved opening 14, and adjust the bolt 4 from bottom to top through the sealing plate 5, the bottom mold steel plate 12, and the sliding sleeve 13, and then screw it into the connecting sleeve 3, so that the sealing steel plate 5 is tightly fitted with the lower end of the reserved opening 14, and the original concrete around the reserved opening 14 is moistened before pouring. After the pouring is completed, the entire set of equipment does not need to be dismantled.
[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principle of the present invention, and these improvements should also be regarded as the protection scope of the present invention.
