[0002] In building construction, a diaphragm wall is a commonly used foundation pit support structure, which has multiple functions such as water stop, soil retaining and load bearing. The diaphragm wall steel reinforcement cage is an important part in diaphragm wall construction, and it consists of main bars, stirrups and I-beam joints, etc. Among them, the I-beam joint is a key component in the diaphragm wall steel reinforcement cage, and its function is to connect the steel reinforcement cage with the diaphragm wall to ensure the stability and integrity of the steel reinforcement cage.

[0003] The I-beam joint of the diaphragm wall steel reinforcement cage is assembled and welded into an I-beam shape by using two flange plates and one web plate. In actual construction, there are some problems in the assembly and welding of the I-beam joint of the diaphragm wall steel reinforcement cage; for example, the traditional method for assembling the I-beam joint of the diaphragm wall steel reinforcement cage is manual positioning and assembly, and this method has problems such as low assembly efficiency, poor accuracy and high construction difficulty. In addition, due to the large weight of the I-beam joint, a lifting device is required to lift and position it during manual assembly, which increases the construction cost and safety risk.

[0004] Therefore, in order to solve the problems existing in the assembly and processing of the I-beam joint of the diaphragm wall steel reinforcement cage, it is necessary to design an assembling jig for the I-beam joint. Summary of the Invention

The vertical support 3 and the inclined support 4 are respectively located at both sides of the top surface of the base 1 and the web support 2 at a certain distance, that is, a certain distance needs to be reserved on both sides of the web support 2 for welding and fixing the vertical support 3 and the inclined support 4, and the reserved space is used for placing the flange plate. The connection methods of the web support 2, the vertical support 3 and the inclined support 4 with the base 1 are fillet welding and full welding. A regulating device 5 for adjusting and pressing the second flange plate 8 of the I-beam against the I-beam web 7 is fixedly connected to the inclined support 4. During assembly, the base 1 is placed on a flat ground.

[0026] The base 1, the web support 2, the vertical support 3 and the inclined support 4 are all made of steel plates. The web support 2 is composed of multiple steel plates welded at intervals on the top surface of the base 1. The size of the steel plate of the base is determined according to the size of the I-beam joint. The width of the web support is smaller than the I-beam web, and the specific width can be considered from the aspects of material saving and the space required for flange plate assembly. The height of the vertical support is determined according to the height of the I-beam. The length and angle of the inclined support are determined according to actual production needs.

[0027] The inclined support 4 is composed of multiple steel plates welded at intervals and obliquely on the top surface of the base 1, and the multiple steel plates are in the same plane.

[0028] The vertical support 3 is composed of multiple steel plates welded at intervals and perpendicularly on the top surface of the base 1, and the multiple steel plates are arranged side by side.

[0029] The regulating device 5 includes a nut 52 and a screw 51 for pressing the second flange plate 8 of the I-beam. The nut 52 is welded and fixed on the inclined support 4, and the screw 51 is threadedly connected with the nut 52. The nut 52 is welded and fixed to the inclined support 4 in the form of fillet welding. When the nut 52 is installed, it is at a certain height from the base 1, and this height is as close as possible to the middle of the flange plate for convenient adjustment and fixation. The screw 51 is a screw with a certain length of external thread, and the screw 51 cooperates with the nut 52, and the size is determined according to the I-beam flange plate.

[0030] An operation handle for facilitating twisting operation is arranged at the end of the screw 51 away from the second flange plate 8 of the I-beam.

[0031] The design and application process of the assembling jig for the I-beam joint of the local wall-connected steel reinforcement cage are as follows: Install the web brace: Place the web brace 2 on the base 1 and perpendicular to the base 1; Use welding to fixedly connect the web brace 2 and the base 1. Install the vertical support: Place the vertical support 3 on one side of the base 1 and perpendicular to the base 1, and weld and fix the vertical support 3 and the base 1. Install the diagonal brace: Weld the bottom end of the diagonal brace 4 to the base 1 to ensure that the diagonal brace 4 is connected to the base 1 at an obtuse angle for easy placement and adjustment of the flange plate. Install the adjusting device: Weld the adjusting device 5 to the side of the diagonal brace 4, screw the screw 51 into the nut 52 to a certain depth, and reserve a certain space to prepare for the subsequent installation and fixation of the flange plate.

[0032] Assemble the I-beam: First step, insert the first flange plate 6 of the I-beam between the web brace and the vertical support, lean against the vertical support to make it vertical.

[0033] Second step, horizontally place the I-beam web 7 on the web brace 2, make the I-beam web 7 close to the first flange plate 6 of the I-beam, and then weld the two.

[0034] Third step, install the second flange plate 8 of the I-beam and make it temporarily lean against the diagonal brace 4.

[0035] Fourth step, adjust the angle and position of the second flange plate 8 of the I-beam to align the second flange plate 8 of the I-beam with the I-beam web 7. Rotate the screw 51 to make the screw 51 and the nut 52 move relative to each other, and the screw 51 presses against the second flange plate 8 of the I-beam. At this time, the base 1, the adjustable device 5, and the vertical support 3 form a stable assembling frame for the I-beam. Finally, weld the second flange plate 8 of the I-beam and the I-beam web 7 to complete the assembling of the I-beam joint. After loosening the screw 51, the I-beam joint can be lifted as a whole away from the assembling jig.

[0036] Repeat the above assembling steps to complete the assembling of multiple I-beam joints.
