DETAILED DESCRIPTION

[0023] In order to make the technical means, creation features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0024] In addition, the terms below are defined based on the functions in the utility model and can be different according to the intentions or habits of users or operators. Therefore, the terms are defined based on the entire content of the specification.

[0025] Referring to Figures 1-5 The assembly box concrete ribbed floor roof and side wall butt joint device comprises a placing plate 1, the placing plate 1 is a component of metal material, the placing plate 1 is horizontally placed on the top of the concrete bottom plate, a metal cylinder 2 is fixedly installed on the upper end face of the placing plate 1, a butt joint pipe 3 is inserted into the inner side of the metal cylinder 2, the cross section of the butt joint pipe 3 is in the shape of a Chinese character You, and the outer side face of the butt joint pipe 3 is a smooth plane;

[0026] The lower end face of the placing plate 1 is embedded with a silica gel pad, when the placing plate 1 is placed on the upper end face of the concrete bottom plate, the silica gel pad directly contacts the upper end face of the concrete bottom plate, the bottom of the silica gel pad is provided with anti-skid lines, the friction between the silica gel pad and the concrete bottom plate is increased, and the placing is more stable;

[0027] The butt joint pipe 3 can be vertically stretched along the metal cylinder 2, the stretching length is determined according to the height of the box wall in the actual construction process, that is, the overall height of the metal cylinder 2 and the butt joint pipe 3 is greater than the height of the box wall;

[0028] A limiting hole 31 is provided at the lower position inside the connecting pipe 3. Guide rods 32 are symmetrically installed on the inner side wall of the connecting pipe 3 near the limiting hole 31. A sliding plate 33 is sleeved on the outer wall of the guide rod 32. Baffles 321 are fixedly installed on the outer wall and end face of the guide rod 32, with the two baffles 321 located on both sides of the sliding plate 33. A return spring 34 is sleeved on the outer wall of the guide rod 32 between the sliding plate 33 and the baffles 321. Locking pins 35 are welded at the center of the end face of the sliding plate 33 facing the limiting hole 31 and are inserted into the limiting hole 31. Locking holes 21 are provided inside the metal cylinder 2, and multiple locking holes 21 are evenly distributed along the longitudinal direction of the metal cylinder 2. The diameters of the locking holes 21 and the limiting holes 31 are... Under normal conditions, the locking pin 35 is positioned within the limiting hole 31 and the locking hole 21 under the action of the return spring 34, locking the positions of the metal cylinder 2 and the connecting tube 3. When it is necessary to adjust the overall height of the metal cylinder 2 and the connecting tube 3, simply press the locking pin 35 through the locking hole 21, causing the sliding plate 33 on one side of the locking pin 35 to slide along the guide rod 32 and squeeze the return spring 34 to generate a rebound force. When the end face of the locking pin 35 is within the limiting hole 31, the connecting tube 3 can be lifted up. When the locking pin 35 moves to the previous position within the locking hole 21, the rebound force generated by the return spring 34 can drive the locking pin 35 back to the locking hole 21 for positioning. Repeating the operation can continue to adjust the support height of the connecting tube 3.

[0029] During the connection operation of the concrete top slab, four of these utility models are placed around the perimeter of the concrete bottom slab (all heights have been adjusted as described above). Construction workers position the metal cylinder 2 by stepping on the placement plate 1. When the concrete top slab is hoisted above the box wall, the hoisting direction is as follows: Figure 1 As shown in direction N, the construction workers control the position of the concrete top slab, ensuring that its four sidewalls enter and align with the sidewall of the connecting pipe 3. This state can be referenced. Figure 1 As shown, the concrete top slab is then lowered. In this method, the concrete top slab falls directly onto the top of the box wall after it is lowered, completing the docking operation between the two. The docking accuracy is high and the operation is convenient.

[0030] Meanwhile, a placement frame 22 is welded to the outer wall of the metal cylinder 2, and a pressing rod 23 is inserted into the placement frame 22. The diameter of the pressing rod 23 is smaller than the diameter of the locking hole 21. When pressing the locking pin 35, the construction personnel can remove the pressing rod 23 and move the locking pin 35 by directly pressing the locking rod 23. This method of operation is safer.

[0031] In another embodiment, see Figures 1-5As shown, the outer end face of the butt joint pipe 3 is provided with a rectangular groove 41, a supporting plate 42 is inserted into the rectangular groove 41, the two side walls of the supporting plate 42 are in contact with the inner side walls of the rectangular groove 41 but are not connected, the blind end face of the supporting plate 42 is welded with a sleeve pipe 43 at the central position, the sleeve pipe 43 is inserted with an inner liner pipe 44, one end of the inner liner pipe 44 is inserted into the outer wall of a supporting rod 45 in the longitudinal direction, the supporting rod 45 is arranged inside the butt joint pipe 3, and the bottom of the supporting rod 45 is fixedly installed with a horizontal plate 46, the bottom of the horizontal plate 46 is connected with the upper end face of the placing plate 1 through a straight rod 461, the outer wall of the supporting rod 45 and between the inner liner pipe 44 and the horizontal plate 46 is sleeved with a supporting spring 47, in the initial state, one end of the supporting plate 42 is exposed outside the rectangular groove 41, and the maximum exposed length is constant, that is, when the supporting plate 42 is located at the top of the rectangular groove 41;

[0033] After the butt joint work of the concrete top plate is completed, the metal cylinder 2 is removed, and the supporting spring 47 drives the components such as the supporting plate 42, the sleeve pipe 43 and the inner liner pipe 44 to reset;

[0034] It should be noted that the horizontal distance between the two ends of the middle segment area (i.e. the inclined area) of the guide rail plate 432, such as Figure 5 the M distance value should not be less than the maximum exposed length of the supporting plate 42 relative to the rectangular groove 41, so that when the supporting rod 431 slides from the top to the bottom of the middle segment area of the guide rail plate 432, the supporting plate 42 can be shrunk into the inner side of the butt joint pipe 3.

[0035] Further, referring to Figures 1-5The end face of the reinforcing plate 423 is embedded with a steel ball, which is in close contact with the inner wall of the butt joint pipe 3, the side wall of the supporting plate 42 is externally supported by the reinforcing plate 423, the supporting plate 42 is not prone to dislocation during movement, and the steel ball can reduce the abrasion between the reinforcing plate 423 and the inner wall of the butt joint pipe 3.
