Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to a U-shaped bolt connection structure. Background Art

[0002] During the installation of U-bolts, such as the U-bolts at the fixing points of the I-beams of cantilever scaffolding, a turnover method is used, that is, a sleeve or protective sleeve is embedded in the floor slab before pouring concrete to form a hole, and then the U-bolt is inserted from the bottom of the floor slab upwards in the hole to fix the I-beam. For the installation process of inserting the bolts, construction workers are usually required to use tools such as mobile scaffolding to climb up and operate at the installation site, which is inconvenient and increases the safety risk of the operation. Utility Model Content

[0003] The utility model aims to overcome the defects of the prior art and provide a U-shaped bolt connection structure to solve the problems of high danger and low work efficiency when personnel need to climb up to wear bolts.

[0004] In order to solve the above technical problems, the utility model is achieved as follows:

[0005] A U-bolt connection structure, characterized in that it comprises a U-bolt, a bolt and a lifting ring, wherein the two ends of the U-bolt are respectively provided with internal threads, the external threads of the bolt match the internal threads of the U-bolt, the bolt is screwed into the U-bolt to achieve connection, and the lifting ring is installed on the top of the bolt.

[0006] The U-bolt connection structure is characterized in that the lifting ring is welded to the nut of the bolt.

[0007] The U-shaped bolt connection structure is characterized in that the length of the internal thread is greater than or equal to the length of the external thread.

[0008] The U-bolt connection structure is characterized in that it also includes a lifting rope, which is connected to the lifting ring. The U-bolt connection structure is lifted and installed by pulling the lifting rope at the installation operation layer.

[0009] The beneficial effects of the utility model are as follows: It can be seen from the above technical solution that the present application provides a U-bolt connection structure, and the U-bolts of the I-beam fixing points of the cantilever scaffolding adopt a turnover type, that is, a pre-buried sleeve or protective sleeve is formed before pouring concrete on the floor slab to form a hole, and then the bolt is inserted from the bottom of the floor slab upwards in the hole, and then the I-beam is fixed. For the installation process of inserting the bolt, the operation is convenient, and the personnel are prevented from having to climb to work when inserting the bolt, which ensures the safety of the operation and improves the installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0014] The technical solutions of the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection requested by the present application.

[0015] like Figure 2 , 3 As shown: a U-bolt connection structure, which includes a U-bolt, a bolt, and a lifting ring. The two ends of the U-bolt are respectively provided with internal threads, the external thread of the bolt matches the internal thread of the U-bolt, the bolt is screwed into the U-bolt to achieve connection, and the lifting ring is installed on the top of the bolt.

[0016] Furthermore, the lifting ring is welded to the nut of the bolt; and the length of the internal thread is greater than or equal to the length of the external thread.

[0017] Furthermore, it also includes a lifting rope, which is connected to the lifting ring. By pulling the lifting rope at the installation operation layer, the U-bolt connection structure is lifted and installed.

[0018] Steps:

[0019] like Figure 1 As shown: tap a section of internal thread 2 at both ends of the U-bolt 1 to form a hole. The length of this section of internal thread needs to be considered when processing the U-bolt, and additional consideration should be given to the design specification length and external thread length;

[0020] Process the mounting bolt 3, the diameter of the mounting bolt matches the internal thread diameter of the U-bolt end, and weld the mounting ring 4 on the upper part of the nut of the mounting bolt;

[0021] During installation, the hanging rope 5 is passed downward through the reserved hole 6 of the working layer at the installation location and extended to the lower floor or the ground;

[0022] Screw the mounting bolt into the end hole of the U-bolt;

[0023] Connect the lifting rope to the installation lifting ring, pull the lifting rope at the working level of the installation location, pass the U-bolt through the reserved hole and install it in place.

[0024] This application is easy to operate; avoids people working at heights; ensures work safety; and improves installation efficiency. Compared with traditional methods, this application improves installation efficiency and safety and has a higher application value.

[0025] The above are only embodiments provided for the present application and are not intended to limit the present application. Although the present application is described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
