Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, and particularly relates to an H-shaped steel facilitating the construction of diaphragm wall piles. Background Art

[0028] Example: Please refer to Figure 1 , Figure 3 and Figure 5 . As shown, there is an H-shaped steel facilitating the construction of diaphragm walls in an embodiment, including an H-shaped steel body 1. Among them, there is also a fitting 2 provided at one end in the length direction of the H-shaped steel body 1; a rib plate 5 connecting the fitting 2 and the H-shaped steel 1; a plug-in member 3 detachably installed with the fitting 2; two hanging members 31 symmetrically arranged at the top of the plug-in member 3 and used for suspending the H-shaped steel body 1; and a fastening assembly 4 for fixing the plug-in member 3 to the fitting 2.
[0029] In this embodiment, as shown in Figure 2 and Figure 3 , the fitting 2 has a cubic structure and is formed with a slot 21 downward from the top. Opposite two side walls of the fitting 2 are provided with first pin holes 22 at corresponding positions. The plug-in member 3 is provided with second pin holes 32 corresponding to the positions of the first pin holes 22.
[0030] In this embodiment, the fastening assembly 4 includes a U-shaped pin 41 and a pin 42. After the U-shaped pin 41 passes through the first pin hole 22 and the second pin hole 32, the pin 42 is inserted into the part of the U-shaped pin 41 exposed from the fitting 2 to fix the plug-in member 3 to the fitting 2.
[0031] In this embodiment, the number of the first pin holes 22 is four in two rows, with two first pin holes 22 in each row, one on the upper side and one on the lower side.
[0032] In this embodiment, the number of the second pin holes 32 is four in two rows, with two second pin holes 32 in each row, one on the upper side and one on the lower side.
[0033] In this embodiment, the number of the U-shaped pins 41 is two, and each U-shaped pin 41 passes through two first pin holes 22 and second pin holes 32, one on the upper side and one on the lower side, in one row.
[0034] In this embodiment, as shown in Figure 4 , the U-shaped pin 41 includes two parallel straight rods 411 and a vertical rod 412 connected to the same side of the two straight rods 411, and there is a fillet transition between the vertical rod 412 and the straight rods 411.
[0035] In this embodiment, an installation hole 413 for the pin 42 to pass through is formed at one end of each straight rod 411 away from the vertical rod 412, and internal threads are provided in any one of the installation holes 413.
[0036] In this embodiment, the pin 42 is provided with external threads 421, and the external threads 421 extend to the position connected to any one of the installation holes 413.
[0037] The characteristics and functions of the present utility model are further understood through the following description.
[0038] In this embodiment, a fitting 2 is installed at the upper end of the H-shaped steel body 1 by welding. A slot 21 is provided in the fitting 2, and a rib plate 5 is provided below the fitting 2. The rib plate 5 connects the fitting 2 and the H-shaped steel body 1, which can enhance the overall stress stability of the H-shaped steel. Two rows of first pin holes 22 are provided on the opposite side walls of the slot 21 for the fastening assembly 4 to pass through. In this embodiment, the plug 3 is preferably a rectangular hammer, which has a certain weight by itself and can be used as a counterweight to assist the H-shaped steel in pile sinking subsequently. Two lifting parts 31 are provided at the top of the plug 3, and the lifting parts 31 are arranged left and right. In this way, when lifting, the wire passes through the two lifting parts 31, and compared with lifting by a single wire, there is sufficient stability and there will be no initial slight left and right shaking. A hanging hole 311 for the wire to pass through is reserved in the lifting part 31, and the lifting part 31 can be inserted into the slot 21. The lower edge of the plug 3 is rounded to facilitate good guiding and insertion into the slot 21. The lifting part 31 can be directly installed on the lifting arm of the pile driver and inserted into the slot 21 during use. Of course, it can also be directly inserted into the slot 21 and then connected to the lifting arm of the pile driver during use, depending on the actual operation situation.
[0039] After the plug 3 is inserted into the slot 21, a U-shaped pin 41 can be inserted into the first pin hole 22 of the slot 21 and the second pin hole 32 of the plug 3, and a pin 42 is screwed into the other side of the U-shaped pin 41 to effectively prevent the accidental sliding out of the U-shaped pin 41. In this embodiment, the pin-type connection method is adopted, which makes the overall installation of the H-shaped steel convenient and at the same time facilitates the adjustment of the posture of the H-shaped steel during the pile insertion process.
[0040] During use, first insert the plug 3 into the slot 21, then fix the plug 3 and the slot 21 through the U-shaped pin 41 and the pin 42, and then pass the wire through the hanging hole 31 of the lifting part and connect it to an external device. Then, the H-shaped steel can be hoisted through the external device, such as a pile driver, and the H-shaped steel can be slowly inserted into the mixing wall. Since the two lifting parts 31 both pass through the wire and are connected to the lifting arm of the pile driver, the stability is effectively improved compared with hoisting by a single steel wire rope, and there will be no left and right shaking of the H-shaped steel. Moreover, when the posture needs to be adjusted, two steel wire ropes are more convenient to adjust than a single steel wire rope.
[0041] In summary, the H-shaped steel of the present utility model is provided with the cooperation of a fitting and a plug. The plug is provided with a lifting part for suspension by an external device, making the H-shaped steel more stable during hoisting and preventing deviation in position and posture in the horizontal direction during pile insertion, and the pile insertion quality is stable.
[0042] The above is only a preferred embodiment of the present utility model, and does not limit the implementation mode and protection scope of the present utility model. For those skilled in the art, it should be realized that all equivalent replacements and obvious changes made by using the description and illustrations of the present utility model should be included in the protection scope of the present utility model.
