Description

Technical Field

[0001] The utility model relates to the field of assembled buildings, in particular to an assembled steel structure wall connection device. Background Art

[0002] The existing assembled wall installation method, such as the scheme with the authorization publication number CN220868500U, is used. First, the fixing rods 2 of the two wall panels correspond to the mounting blocks 3, and the fixing rods 2 are inserted into the mounting blocks 3, so that the fixing rods 2 are completely inserted into the mounting blocks 3, and the limiting blocks 4 and the limiting grooves 13 are completely corresponding. After the two wall panels are initially limited, the threaded rods 6 are rotated through the threaded holes 5 to be fixed to the fixing blocks 7. Although the connection and welding of the nuts are reduced to a certain extent, the workload is reduced, but the following problems still exist:

[0003] 1. It is necessary to lift one wall panel upwards before inserting the fixing rod 2 into the mounting block 3 of another wall panel. After the wall panel is lifted, the wall panel will shake, and it will be difficult to match the fixing rod 2 and the mounting block 3 during installation, which increases the difficulty of installation. When the upper space is limited, installation cannot be performed.

[0004] 2. First, the limit block 4 and the limit groove 13 are completely aligned, and then the threaded rod 6 is rotated through the threaded hole 5 to be fixed to the fixed block 7, which can play a preliminary limiting role. However, when the fixed rod 2 moves downward too much, the threaded hole will still be misaligned in the up and down directions, making it difficult to screw the threaded rod in. At the same time, each threaded rod still needs to be rotated multiple times before the threaded rod 6 can be completely screwed in, resulting in low efficiency. Summary of the invention

A vertically arranged paving groove 5 is provided at the bottom of the countersunk hole 4. The paving groove 5 is connected to the plurality of countersunk holes 4 on the wall panel 1. A baffle 6 is installed in the paving groove 5. The right end face of the rectangular block 2 is fixed on the left end face of the baffle 6. The left and right movement of the baffle 6 can drive the rectangular block 2 to move left and right.

[0027] A straight slot 7 penetrating into the give-way slot 5 is provided on the left side of the front end surface of the wall panel 1. The straight slots 7 are arranged left and right. A round rod 8 is fixed to the front end surface of the baffle 6. The round rod 8 is placed in the straight slot 7. The round rod 8 moves along the length direction of the straight slot 7 to drive the baffle 6 to move left and right. The middle part of the front end of the round rod 8 is concave inwards.

[0028] The depression on the round rod 8 facilitates the round rod 8 to be pushed.

[0029] A limiting hole 9 is provided on the rear end face of each groove 3, and a through hole 10 is provided on the front end face of each groove 3 and penetrates to the front end face of the wallboard 1. The through hole 10 consists of two parts. The front side of the through hole 10 is a threaded hole, and the rear side of the through hole 10 is a square hole, and the diameter of the threaded hole is larger than the diameter of the circumscribed circle of the square hole.

[0030] A bolt 11 is rotated in the threaded hole of the through hole 10, and a stopper 12 is inserted in the square hole of the through hole 10. The stopper 12 is rotatably connected with the bolt 11, and the bolt 11 can move the stopper 12 backward; the rear side of the stopper 12 is located through the groove 3 and placed in the limiting hole 9, and the right end face of the stopper 12 contacts the right end face of the square hole of the through hole 10, and the right end face of the stopper 12 contacts the right end face of the giving way hole;

[0031] The front end of the left end face of the stopper 12 is located on the left side of the rear end;

[0032] A rectangular hole 13 is formed on the front face of the rectangular block 2, and the front end of the left end of the rectangular hole 13 is located on the left side of the rear end; the left end face of the rectangular hole 13 is parallel to the left end face of the stopper 12;

[0033] When the rectangular block 2 on the wall panel 1 on the right side of two adjacent wall panels 1 is placed in the groove 3 on the wall panel 1 on the right side, the block 12 and the bolt 11 are moved backward through the through hole 10, and the rear end of the block 12 is passed through the rectangular hole 13 of the block 12 and placed in the clearance hole. At this time, the left end face of the block 12 is fitted with the left end face of the rectangular hole 13 on the rectangular block 2, and then the bolt 11 is rotated to move backward. The bolt 11 can push the rectangular block 2 to move leftward through the left end face of the block 12, so that the two adjacent wall panels 1 are tightly fixed together.

[0034] A coaxial circular hole is provided on the rear side of the bolt 11, and the diameter of the bottom of the circular hole is larger than the diameter of the opening; a cylindrical block is fixed on the front side of the stopper 12, and the front end diameter of the cylindrical block is larger than the rear side. The cylindrical block is placed in the circular hole and rotates relatively around the axis of the bolt 11, so that the cylindrical block and the bolt 11 are not separated.

[0035] The four left sides of each rectangular block 2 are rounded.

[0036] Before the utility model is used, the bolt 11 and the stopper 12 are separated from the through hole 10, and the rectangular block 2 is placed in the wallboard 1;

[0037] When the utility model is used, two adjacent wall panels 1 are placed close to each other and arranged left and right, so that the countersunk holes 4 on the wall panel 1 on the right side correspond to the grooves 3 on the wall panel 1 on the right side, and then the round rod 8 on the wall panel 1 on the right side is pushed to move to the left, and the round rod 8 moves the rectangular block 2 to the left through the baffle 6, and the left end of the rectangular block 2 moves out of the countersunk hole 4 and is placed in the groove 3 on the wall panel 1 on the left side, until the baffle 6 contacts the left end surface of the clearance groove 5, and stops pushing the round rod 8;

[0038] Then, insert the block 12 and the bolt 11 into the through hole 10 on the left wall panel 1 one by one, and the rear end of the block 12 passes through the rectangular hole 13 of the block 12 and is placed in the make way hole. At this time, the left end face of the block 12 is in contact with the left end face of the rectangular hole 13 on the rectangular block 2. Then, rotate the bolt 11 to move backward in sequence. The bolt 11 can push the rectangular block 2 to move leftward through the left end face of the block 12, and the two adjacent wall panels 1 are tightly fixed together under the obstruction of the baffle 6. At this point, the installation and fixation of the two adjacent wall panels 1 are completed.

[0039] 1. The utility model first moves the rectangular block 2 into the wall, and then moves two adjacent wall panels 1 closer together for installation, which solves the problem of difficult installation by hoisting and positioning, and can also solve the problem that when the space is limited, the two adjacent wall panels 1 can be moved closer together in the front and back directions, and the operation is simple and convenient;

[0040] Since the rectangular block 2 is moved inwards and then placed in the cavity, it will not be bumped during the movement, thus preventing the connection from being deformed due to bumps.

[0041] 2. The utility model realizes the relative rotation of the bolt 11 and the stopper 12, and the rear ends of the left end faces of the stopper 12 and the left end faces of the rectangular hole 13 are located on the left side of the front end. When the bolt 11 rotates backward, only a short rotation distance is required to enable the stopper 12 to push the rectangular block 2 to move leftward, so that the two adjacent wall panels 1 are tightly fixed, thereby preventing the problem that when the two adjacent wall panels 1 are simply fixed by the bolts 11, the threaded holes on the two wall panels 1 are misaligned, making it difficult to screw the bolts 11 in.
