Description

Technical Field

[0001] This utility model relates to the field of rebar tying technology, and in particular to a rebar installation device for a steel truss floor slab. Background Technology

[0002] In modern construction engineering, with the acceleration of urbanization and the continuous development of building technology, various buildings have placed higher demands on structural stability, space utilization, and construction efficiency. To avoid problems such as reduced interior ceiling height, uneven floor surfaces, corrosion protection, and fire resistance, the use of reinforced steel truss floor decks is becoming increasingly widespread. Reinforced steel truss floor decks are formed by processing the reinforcing bars in the floor slab into steel trusses in a factory and welding them to galvanized profiled steel sheets, thus improving the quality of floor slab construction.

[0003] However, since the position and spacing of the steel truss are fixed, the binding of the top of the steel truss requires passing through the top chord of the truss, which makes it difficult for workers to move and reduces construction efficiency. How to increase the construction efficiency of binding the top steel bars of the steel truss floor slab is a major problem that plagues on-site construction.

[0004] Therefore, there is an urgent need to design a device for binding and installing steel reinforcement in steel truss floor slabs to solve the problems existing in the current technology. Utility Model Content

[0029] Example 1

[0030] like Figure 1-5 As shown, a steel reinforcement installation device for a steel truss floor slab includes an irregular annular one-way spring lock. The one-way spring lock has an opening / closing section 4 and a rotating section 2 on each side, connected by a mating section 3. The opening / closing section 4 can only open inwards. The bottom end of the opening / closing section 4 is rotatably connected to the mating section 3 via a rotating shaft. A return spring is sleeved on the outside of the rotating shaft, with both ends of the return spring inserted into the mating section 3. When pressure is applied to the opening / closing section 4, the return spring compresses and rotates, opening the opening / closing section 4 inwards. After the external force disappears, the opening / closing section 4 returns to its original position and closes under the action of the return spring. The return spring structure is omitted in the figure. A U-shaped groove 401 is provided at the top of the opening / closing section 4, and a limiting block 301 is provided on the outer side of the upper mating section 3. A hook 302 is provided at the bottom of the limiting block 301 near the opening / closing section 4. The hook 302 can engage with the U-shaped groove 401, ensuring a secure engagement between the opening / closing section 4 and the hook 302 after the opening / closing section 4 returns to its original position, preventing the opening / closing section 4 from slipping outwards.

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

[0032] The rotating section 2 includes a rotating gear rotatably connected to the lower mating section 3. The rotating gear includes several sector-shaped teeth 201, each tooth 201 including two opposing tooth plates 202. Each tooth plate 202 has a curved locking block 203 on one opposite side of its end. The lower mating section 3 has an I-beam slide rail 303 at its bottom. The locking block 203 engages with the slide rail 303 and can slide along the slide rail 303. The distance between the I-beam slide rail 303 and the center of the rotating section 2 is greater than the diameter of the reinforcing bar 6 to be tied. The distance between the ends of adjacent teeth 201 is also greater than the diameter of the reinforcing bar 6 to be tied, facilitating the passage of the reinforcing bar 6 between the teeth 201. The distance between the ends of adjacent teeth 201 is less than the length of the slide rail 303, preventing the rotating section 2 from slipping off the mating section 3. The reinforcing bar 6 to be tied can pass through the rotating section 2, which remains connected to the mating section 3 during rotation. The lower mating section 3 also has an I-beam slide rail 303, ensuring stable and smooth rotation of the rotating section 2.

[0033] The one-way spring lock has a handle 1 at its top and a rebar fixing part 5 at its bottom. The rebar 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 rebar 6 to be tied, facilitating the passage of the rebar 6 through the limiting groove 501 and adapting to different rebar types. An adjustment component is provided on the bottom side wall of the limiting groove 501. The adjustment component includes an abutment block 502 located within the limiting groove 501. One end of a screw rod 503 is connected to the bottom of the abutment block 502, and the other end of the screw rod 503 passes downward through the side wall of the limiting groove 501 and connects to a nut 504. The abutment block 502 abuts against the bottom of the rebar 6 to be tied. By rotating the nut 504, the length of the screw rod 503 between the bottom of the rebar 6 and the side wall of the limiting groove 501 can be adjusted, facilitating the locking of the rebar 6 and preventing displacement during the tying process. The handle 1 is parallel to the axis of the limiting groove 501, making operation more convenient. The preferred length of the handle 1 is 25-35cm.

[0034] Working principle:

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

[0036] The worker holds the handle 1 and aligns the steel bar 6 to be tied with the upper chord bar 7 of the steel truss floor slab perpendicularly, between the two web members 8, and below the upper chord bar 7. The device is pushed forward, and the upper chord bar 7 opens the closing section 4 and enters the one-way spring lock. After the opening and closing section 4 loses external force, it resets under the action of the return spring and engages with the hook 302 to lock. The upper chord bar 7 approaches the rotating section 2 and enters the gap between the adjacent gear teeth 201. The locking block 203 slides along the slide rail 303 to complete the rotation, thereby driving the upper chord bar 7 to leave the one-way spring lock and completing the installation of this row of steel bars.

[0037] The operators are skilled in using it, and the entire installation process can be completed while walking without stopping.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
