[0002] When erecting a scaffolding in the current construction industry, according to the common tie methods mentioned in the current specification Q / PJAY JSGF051-2021, there are three forms: embedded steel bar tie members, embedded flat iron tie members, and embedded steel pipe tie members. Currently, the above-mentioned tie methods all require prior positioning with the inner vertical poles of the erected scaffolding, and there should be no excessive angular deviation from the inner vertical poles of the scaffolding. Otherwise, it is easy to occur that the tie rod cannot be tied to the scaffolding due to positioning deviation, and the positioning step is usually time-consuming and laborious. Summary of the Utility Model

[0003] The main purpose of the utility model is to propose a scaffolding tie connection device, which is convenient for tying to the scaffolding.

[0004] The utility model provides a scaffolding tie connection device, including:

[0005] An installation column, one end of which is used for being embedded in a structural floor;

[0006] A tie rod, one end of which has an opening, and the other end of which is used for connecting to the inner vertical pole of the scaffolding. The tie rod passes through the installation column through the opening and can rotate with the installation column as a rotation axis;

[0007] A first fixing member, which is used for fixing the tie rod on the installation column; and

[0008] A second fixing member, which is used for fixedly connecting the tie rod and the inner vertical pole of the scaffolding.

[0009] In one embodiment, one end of the tie rod is detachably connected to the installation column, and the other end is detachably connected to the inner vertical pole of the scaffolding.

[0010] In one embodiment, the installation column is a bolt, the first fixing member includes a gasket and a nut. The gasket is sleeved on the installation column and is located on the side of the tie rod away from the structural floor, and the nut is screwed onto the bolt and presses on the side of the gasket away from the structural floor.

[0011] In one embodiment, the first fixing member presses the tie rod passing through the installation column onto the structural floor.

[0012] In one embodiment, a bearing plate is sleeved on the installation column, the bearing plate is arranged at an interval from the structural floor slab, and the first fixing member presses the tie rod passing through the installation column onto the bearing plate.

[0013] In one embodiment, the second fixing member includes a fastener; and / or

[0014] The tie rod is a steel pipe.

[0015] In one embodiment, the overlapping length of the tie rod and the structural floor slab is 300 mm - 700 mm, and the length of the tie rod extending to the outside of the structural floor slab is 700 mm - 1200 mm.

[0016] In one embodiment, there is one installation column, and the distance between the installation column and the outside of the structural floor slab is 200 mm - 400 mm.

[0017] In one embodiment, there are multiple installation columns, and the multiple installation columns are arranged at intervals along the length direction of the tie rod. The number of the openings is the same as the number of the installation columns and they are arranged in one-to-one correspondence.

[0018] The present utility model further provides a scaffolding system, including:

[0019] A scaffolding; and

[0020] The above-mentioned scaffolding tie connection device, wherein the first fixing member fixes the tie rod on the installation column, and the second fixing member fixedly connects the tie rod and the inner vertical pole of the scaffolding.

[0021] When using the above-mentioned scaffolding tie connection device, the installation column can be pre-embedded in the structural floor slab first, then the tie rod is passed through the installation column through the opening, and then the inner vertical pole of the scaffolding is erected on the outside of the structural floor slab. When there is a large angular deviation between the tie rod and the inner vertical pole, resulting in the inability of the tie rod and the inner vertical pole to overlap and thus unable to be connected, the angular deviation between the tie rod and the inner vertical pole can be adjusted by controlling the rotation of the tie rod around the installation column, so that the tie rod and the inner vertical pole can overlap and thus the tie rod and the inner vertical pole can be connected. After adjusting the position of the tie rod, the tie rod can be fixed on the installation column by the first fixing member. Then the tie rod and the inner vertical pole of the scaffolding can be fixedly connected by the second fixing member, completing the step of connecting the structural floor slab and the inner vertical pole of the scaffolding through the scaffolding tie connection device. Finally, other components of the scaffolding can be installed on the inner vertical pole.

[0022] In the above-mentioned scaffolding tie connection device, since the tie rod is passed through the installation column through an opening and can rotate with the installation column as the rotation axis, the tie rod can rotate at multiple angles, and thus it is very convenient to adjust the angular deviation between the tie rod and the inner vertical rod. When using the above-mentioned scaffolding tie connection device to connect the structural floor slab and the inner vertical rod of the scaffolding, only a rough positioning step for the scaffolding tie connection device and the inner vertical rod of the scaffolding needs to be carried out in advance, and a more accurate positioning step for the scaffolding tie connection device and the inner vertical rod of the scaffolding does not need to be carried out in advance, and the scaffolding tie connection device can connect the structural floor slab and the inner vertical rod of the scaffolding. Therefore, the above-mentioned scaffolding tie connection device is very convenient for tying with the scaffolding, which can not only effectively shorten the construction time, but also avoid the situation of material waste caused by large positioning deviation.

The scaffolding tie connection device 300 connects the structural floor slab 400 and the inner vertical rod 210 of the scaffolding 200.

[0028] In this embodiment, the scaffolding 200 further includes an outer vertical rod 220 corresponding to the inner vertical rod 210 and a horizontal tie rod 230 connecting the inner vertical rod 210 and the outer vertical rod 220.

[0029] In this embodiment, there are multiple inner vertical poles 210, and the multiple inner vertical poles 210 are arranged at intervals. The number of the scaffolding tie connection devices 300 is the same as that of the inner vertical poles 210 and they are arranged in a one-to-one manner. The number of the outer vertical poles 220 is the same as that of the inner vertical poles 210 and they are arranged in a one-to-one manner. In this embodiment, the above-mentioned scaffolding system 10 further includes a rigid isolation 500. The rigid isolation 500 is arranged on the multiple scaffolding tie connection devices 300 to prevent the staff from stepping into the air through the gap between two adjacent scaffolding tie connection devices 300.

[0030] In this embodiment, the scaffolding 200 further includes an inner guardrail 240 and an outer guardrail 250. The inner guardrail 240 is connected to the multiple inner vertical poles 210. The outer guardrail 250 is connected to the multiple outer vertical poles 220.

[0031] In this embodiment, the scaffolding 200 further includes a scaffold board 260 which is arranged on the horizontal tie rod 230 and connects the inner vertical pole 210 and the outer vertical pole 220. Specifically, in this embodiment, both the inner vertical pole 210 and the outer vertical pole 220 are socketed type disk-locked steel pipes. The horizontal tie rod 230 and the scaffold board 260 are both made of steel.

[0032] In this embodiment, the scaffolding 200 further includes a toe board 270 which is arranged on the outer vertical pole 220 and is used in cooperation with the scaffold board 260.

[0033] In this embodiment, as Figure 2 and Figure 3 shown, the scaffolding tie connection device 300 includes an installation column 310, a tie rod 320, a first fixing member 330 and a second fixing member. One end of the installation column 310 is used for being embedded in the structural floor slab 400. One end of the tie rod 320 has an opening 322, and the other end is used for connecting with the inner vertical pole 210 of the scaffolding 200. The tie rod 320 passes through the installation column 310 through the opening 322 and can rotate with the installation column 310 as the rotation axis. The first fixing member 330 is used for fixing the tie rod 320 on the installation column 310. The second fixing member is used for fixedly connecting the tie rod 320 and the inner vertical pole 210 of the scaffolding 200.

[0034] When using the above-mentioned scaffolding tie connection device 300, the installation column 310 can be pre-embedded in the structural floor slab 400 first, and then the tie rod 320 is passed through the opening 322 and set on the installation column 310. Then, the inner vertical rod 210 of the scaffolding 200 is erected on the outside of the structural floor slab 400. When there is a large angular deviation between the tie rod 320 and the inner vertical rod 210, resulting in the inability of the tie rod 320 and the inner vertical rod 210 to overlap and thus unable to be connected, the angular deviation between the tie rod 320 and the inner vertical rod 210 can be adjusted by controlling the rotation of the tie rod 320 around the installation column 310, so that the tie rod 320 and the inner vertical rod 210 can overlap and thus the tie rod 320 and the inner vertical rod 210 can be connected. After adjusting the position of the tie rod 320, the tie rod 320 can be fixed to the installation column 310 through the first fixing member 330. Then, the tie rod 320 and the inner vertical rod 210 of the scaffolding 200 can be fixedly connected through the second fixing member, completing the step of connecting the structural floor slab 400 and the inner vertical rod 210 of the scaffolding 200 through the scaffolding tie connection device 300. Finally, other components of the scaffolding 200 can be installed on the inner vertical rod 210.

[0035] In the above-mentioned scaffolding tie connection device 300, since the tie rod 320 is passed through the opening 322 and set on the installation column 310 and can rotate with the installation column 310 as the axis of rotation, the tie rod 320 can rotate at multiple angles, which is very convenient for adjusting the angular deviation between the tie rod 320 and the inner vertical rod 210. When using the above-mentioned scaffolding tie connection device 300 to connect the structural floor slab 400 and the inner vertical rod 210 of the scaffolding 200, only a rough positioning step for the scaffolding tie connection device 300 and the inner vertical rod 210 of the scaffolding 200 needs to be carried out in advance, and a more precise positioning step for the scaffolding tie connection device 300 and the inner vertical rod 210 of the scaffolding 200 does not need to be carried out in advance, and the scaffolding tie connection device 300 can connect the structural floor slab 400 and the inner vertical rod 210 of the scaffolding 200. Therefore, the above-mentioned scaffolding tie connection device 300 is very convenient for tying with the scaffolding 200, which can not only effectively shorten the construction time, but also avoid the situation of material waste caused by large positioning deviation.

[0036] In this embodiment, one end of the tie rod 320 is detachably connected to the installation column 310, and the other end is detachably connected to the inner vertical rod 210 of the scaffolding 200. In this way, the tie rod 320 can be reused, which is beneficial to cost saving.

[0037] In this embodiment, the mounting post 310 is a bolt. The first fixing member 330 includes a gasket 332 and a nut 334. The gasket 332 is sleeved on the mounting post 310 and is located on the side of the tie rod 320 away from the structural floor slab 400. The nut 334 is screwed onto the bolt and presses on the side of the gasket 332 away from the structural floor slab 400. In this way, it is very convenient to detachably connect one end of the tie rod 320 to the mounting post 310. It can be understood that in other embodiments, the first fixing member 330 can also be a welding material connecting the tie rod 320 and the mounting post 310.

[0038] In this embodiment, the second fixing member includes a fastener. In this way, it is very convenient to detachably connect the other end of the tie rod 320 to the inner vertical pole 210 of the scaffold 200.

[0039] In this embodiment, the tie rod 320 is a steel pipe. In this way, it is very convenient to form an opening 322 in the tie rod 320.

[0040] In this embodiment, the overlapping length of the tie rod 320 and the structural floor slab 400 is 300 mm - 700 mm. The length of the tie rod 320 extending to the outside of the structural floor slab 400 is 700 mm - 1200 mm. In this way, it is very convenient for the tie rod 320 to stably connect to the scaffold 200. Specifically, in this embodiment, the length of the tie rod 320 is 1500 mm, the overlapping length of the tie rod 320 and the structural floor slab 400 is 400 mm, and the length of the tie rod 320 extending to the outside of the structural floor slab 400 is 1100 mm.

[0041] In this embodiment, there is one mounting post 310. The distance between the mounting post 310 and the outside of the structural floor slab 400 is 200 mm - 400 mm. In this way, it is very convenient for the mounting post 310 to stably connect to the tie rod 320. Specifically, in this embodiment, the distance between the mounting post 310 and the outside of the structural floor slab 400 is 300 mm. In other embodiments, there can also be multiple mounting posts 310. The multiple mounting posts 310 are arranged at intervals along the length direction of the tie rod 320. The number of the openings 322 is the same as the number of the mounting posts 310 and they are arranged in a one-to-one manner.

[0042] In this embodiment, a bearing plate 340 is sleeved on the installation column 310. The bearing plate 340 is arranged at an interval from the structural floor slab 400. The first fixing member 330 presses the tie rod 320 passing through the installation column 310 onto the bearing plate 340. In this way, not only can the stable installation of the tie rod 320 be achieved, but also tools such as a saw can be used to disconnect the installation column 310 at the interval between the bearing plate 340 and the structural floor slab 400, so that the tie rod 320, the first fixing member 330 and the bearing plate 340 are separated from the structural floor slab 400, and further the removal of the scaffolding tie connection device 300 is realized, which is very convenient for removing the scaffolding tie connection device 300. It can be understood that in other embodiments, the bearing plate 340 can also be omitted. At this time, the first fixing member 330 presses the tie rod 320 passing through the installation column 310 onto the structural floor slab 400, and the stable installation of the tie rod 320 can also be achieved.
