Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of engineering construction equipment, and particularly relates to a butt joint device for a lifting side beam of a steel skeleton. Background Technique
[0002] The precast floor slabs adopted in existing buildings are not absolutely easy to use. It is very difficult to align the positioning holes during the assembly of the wall body. If there are deviations, the positioning steel bars may be directly sawed off, resulting in poor firmness of the wall body splicing. Moreover, problems such as poor sealing and cracking may occur in the gaps between the wall bodies in the later stage. It can be carried out through a precast forming skeleton, which belongs to a semi-precast construction method, and can fully fix the forming skeletons and avoid the problem of poor sealing of the gaps between the wall bodies. Existing research and development uses an M-shaped steel forming skeleton as the main structural support, and then binds and fixes the steel bars to form a steel bar cage in the shape of a plate body, greatly reducing the assembly time of the forming skeleton and improving the efficiency.
[0003] As the main rigid support inside the wall body, the forming skeleton still needs to be transported and assembled after the precast steel bar cage. Since the steel bars are fixed by bundling or welding, directly lifting the forming skeleton will cause uneven local stress, and the forming skeleton will deform due to the unstable center of gravity position. When lifting the steel skeleton, a fixture is prepared, which consists of two square tubes and a cross beam between them. The two square tubes are parallel to each other, and a square frame structure is formed after installing the cross beam. The square tubes are located on the side of the steel skeleton, abut against the steel bar cage on the side of the steel skeleton and are fixed by support members. Therefore, the length of the square tube needs to be the same as or similar to the longitudinal length of the steel skeleton, and the difference cannot be too large. For walls with different specifications, the corresponding steel skeleton specifications are also different, so the length of the square tube needs to be adjusted to meet the requirements. The traditional flange butt joint is very difficult to align the positions of the screw holes, and the installation is rather troublesome. Content of the Utility Model
[0004] The purpose of the utility model is to provide a butt joint device for a lifting side beam of a steel skeleton, which avoids the problem that the screw holes are difficult to align caused by the flange butt joint installation method, realizes convenient and accurate positioning, quick installation and small error.
[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The length of the square tube is adjustable, and it has a main pipe and a sub-pipe. The main pipe and the sub-pipe are butt-jointed through a connecting pipe to form an integral body. The corresponding butt-joint ends of the main pipe and the sub-pipe are in a sealed state, and sleeves extending inward are arranged on both of them;
[0008] Both ends of the connecting pipe are in a sealed state and are provided with positioning rods for inserting the sleeve, and the positioning rods are fixed by locking members after being inserted into the sleeve.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0019] As Figures 1-4Shown: A butt joint device for a steel skeleton hoisting side beam. The side beam is a square tube, and there are two square tubes, which are respectively located on the left and right sides of the steel skeleton 4 and extend along the length direction of the steel skeleton 4. A cross beam 5 is connected between the two side square tubes to form a square frame structure;
[0020] The square tubes are steel tubes with a square cross-section and are parallel to each other. The cross beam is located on one side of the square tubes. The cross beam is a channel beam symmetrically arranged on both sides and is formed by two inner-button vertical bends of a steel plate. The middle line has an installation groove, and the end is fixed by welding a connecting plate. Bolts are installed at the cross positions corresponding to the square tubes and the cross beam for fixation. Multiple through holes are provided in the corresponding length direction of the square tubes to cooperate with the installation groove corresponding to the middle line of the cross beam. According to the specifications of the steel skeleton, the position of the cross beam is adjusted to achieve the best stability effect.
[0021] The length of the square tube is adjustable and has a main pipe 1 and a sub-pipe 2. The main pipe 1 and the sub-pipe 2 are butt-jointed into an integral body through a connecting pipe 3. The butt-jointed ends of the main pipe 1 and the sub-pipe 2 are both in a sealed state, and sleeves 11 extending inward are provided; the main pipe, the sub-pipe, and the connecting pipe are all pipe body structures with a square cross-section. A sealing plate is welded and fixed at the butt-jointed end. The sealing plate is square. The butt-jointed integral pipe body structure is used as a fixture, and the four corresponding sides of the pipe body are on the same horizontal plane.
[0022] Both ends of the connecting pipe 3 are in a sealed state and have positioning rods 31 for inserting the sleeves 11. After the positioning rods 31 are inserted into the sleeves, they are fixed by locking parts. The connecting pipe and the corresponding main pipes and sub-pipes on both sides are positioned by the positioning rods, then inserted, and finally the ends of the positioning rods are fixed by the locking parts, so that the main pipe, the sub-pipe, and the connecting pipe become an integral body, avoiding the problem of difficult alignment of screw holes caused by the flange butt-joint structure, and can quickly complete the butt joint to adapt to steel skeletons of different specifications.

The sleeve 11 is a sleeve with a square cross-section for inserting the square limit block 32. The other end of the positioning rod 31 is a threaded end. The square limit block is a cylindrical structure, coaxially arranged with the positioning rod, and is vertically fixed at the center of the end face of the connecting pipe. After the limit block is inserted into the sleeve, it plays a role in preventing torsion, and the length of the threaded end exceeds the length of the sleeve and has an extended part. The locking part is a nut 33 for cooperating with the threaded end of the positioning rod 31. A gasket 34 is also installed between the nut 33 and the sleeve 11. The gasket 34 is annular and sleeved on the threaded end of the positioning rod 31. The cooperation of the nut and the gasket is used to limit the positioning rod and lock the positioning rod to prevent it from falling off. Installation grooves 12 are provided at the corresponding sleeve ends of the main pipe 1 and the sub-pipe 2. The installation grooves 12 are opened on the side wall of the pipe body. The installation grooves are used to install the nut and rotate the nut.
