[0029] Example 1

[0030] like Figure 1-5 As shown, a steel bar installation device for steel bar truss floor decking plate includes an irregular annular one-way spring lock, and an opening and closing section 4 and a rotating section 2 are respectively arranged on both sides of the one-way spring lock, and the opening and closing section 4 and the rotating section 2 are connected by a matching section 3, and the opening and closing section 4 can only be opened inwardly, and the bottom end of the opening and closing section 4 is connected to the matching section 3 by a rotating shaft, and a reset spring is sleeved on the outer side of the rotating shaft, and both ends of the reset spring are inserted on the matching section 3, and pressure is applied to the opening and closing section 4, and the reset spring is compressed and rotated, and the opening and closing section 4 opens inwardly. After the external force disappears, the opening and closing section 4 is reset and closed under the action of the reset spring, and the reset spring structure is omitted in the figure. A U-shaped groove 401 is arranged at the top of the opening and closing section 4, and a limit block 301 is arranged on the outer side of the end of the upper matching section 3, and a hook 302 is arranged at the bottom of the limit block 301 near the opening and closing section 4. The hook 302 can be engaged with the U-shaped groove 401, so that the opening and closing section 4 is firmly engaged with the hook 302 after being reset, and the opening and closing section 4 is prevented from slipping when opening outward.

[0031] The inner width of the one-way spring lock decreases from the opening and closing section 4 to the rotating section 2. The inner wall of the one-way spring lock is streamlined, so that the upper chord rib 7 slides toward the rotating section 2 when passing through the one-way spring lock, making it easier to escape from the rotating section 2.

[0032] The rotating section 2 includes a rotating gear rotatably connected with the lower matching section 3. The rotating gear includes a plurality of sector-shaped gear teeth 201. Each gear tooth 201 includes two opposite tooth pieces 202. The ends of the tooth pieces 202 are provided with curved clamping blocks 203 on opposite sides. An I-shaped slide rail 303 is provided at the bottom of the upper matching section 3. The clamping block 203 engages with the slide rail 303, and the clamping block 203 can slide along the slide rail 303. The distance between the I-shaped slide rail 303 and the center of the rotating section 2 is greater than the diameter of the steel bar 6 to be tied. The distance between the ends of adjacent gear teeth 201 is greater than the diameter of the steel bar 6 to be tied, so that the steel bar 6 to be tied can pass through between the gear teeth 201. The distance between the ends of adjacent gear teeth 201 is less than the length of the slide rail 303, so as to prevent the rotating section 2 from slipping off the matching section 3. The steel bar 6 to be tied can pass through the rotating section 2, and the rotating section 2 is always connected to the matching section 3 when rotating. The lower matching section 3 is also provided with an I-shaped slide rail 303, so that the rotation of the rotating section 2 is stable and smooth.

[0033] A gripping handle 1 is provided at the top of the one-way spring lock, and a steel bar fixing part 5 is provided at the bottom of the one-way spring lock. The steel bar fixing part 5 includes a limiting groove 501 at the bottom of the one-way spring lock. The limiting groove 501 is larger than the diameter of the steel bar 6 to be tied, so that the steel bar 6 to be tied can pass through the limiting groove 501 to meet the needs of different types of steel bars. An adjustment component is provided on the bottom side wall of the limiting groove 501. The adjustment component includes an abutment block 502 located in the limiting groove 501. The bottom of the abutment block 502 is connected to one end of a screw rod 503, and the other end of the screw rod 503 passes downward through the side wall of the limiting groove 501 to connect a nut 504. The abutment block 502 abuts against the bottom of the steel bar 6 to be tied. By rotating the nut 504, the length of the screw rod 503 between the bottom of the steel bar 6 to be tied and the side wall of the limiting groove 501 can be adjusted, so as to lock the steel bar 6 to be tied and prevent it from displacement during the tying process. The gripping handle 1 is parallel to the axis of the limiting groove 501, which is more convenient to operate. Preferably, the length of the gripping handle 1 is 25-35 cm.

[0034] Working principle:

[0035] Pass one end of the steel bar 6 to be tied through the limiting groove 501, rotate the nut 504 to make the end of the screw 503 abut against the block 502 to press the steel bar 6 to be tied, and confirm that it is locked firmly;

[0036] The staff holds the gripping handle 1 to make the steel bar 6 to be tied perpendicular to the upper chord 7 of the steel truss floor decking, located between the two web members 8 and below the upper chord 7; push the device forward, the upper chord 7 pushes the opening and closing section 4, and enters the inside of the one-way spring lock. After the opening and closing section 4 loses external force, it is reset under the action of the reset spring and locked with the hook 302; the upper chord 7 approaches the rotating section 2 and enters the gap between adjacent gear teeth 201, and the block 203 slides along the slide rail 303 to complete the rotation, thereby driving the upper chord 7 to leave the one-way spring lock and completing the installation of the row of steel bars.

[0037] The operators are skilled in the application and can complete the entire installation process without stopping during walking.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
