Detailed Description

The present invention provides a suspended scaffold structure, which will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 2, the suspended scaffold structure provided in this embodiment includes a wall 1, two bolts having their screw thread portions extending out of the wall 1 from the outer side surface of the wall 1 are pre-embedded in the wall 1, and each bolt is a first bolt 21 and a second bolt 22, the first bolt 21 and the second bolt 22 are sequentially distributed from top to bottom along the longitudinal direction, the suspended scaffold structure further includes a support bar 3 horizontally arranged, a protection bar 4 longitudinally arranged, and a telescopic connecting rod 5, the screw thread portion of the second bolt 22 is inserted into one end of the support bar 3 and is in threaded connection with the support bar 3, the bottom end of the protection bar 4 is fixedly connected to one end of the support bar 3 away from the second bolt 22, the telescopic connecting rod 5 is mainly composed of a first screw 51, a first sleeve 52, a second sleeve 53, and a second screw 54 sequentially arranged along the axial direction thereof, the first sleeve 52 and the second sleeve 53 are coaxially connected, and the opening directions of the inner holes of the two sleeves are opposite, the inner bores of the first sleeve 52 and the second sleeve 53 are internally provided with internal threads with opposite thread directions, the first screw 51 is inserted into the first sleeve 52 and is in threaded connection with the first sleeve 52, and the second screw 54 is inserted into the second sleeve 53 and is in threaded connection with the second sleeve 53, the end of the first screw 51 far away from the first sleeve 52 is hinged with the threaded part of the first bolt 21, the end of the second screw rod 54 far away from the second sleeve 53 is hinged with the top end of the protective strip 4, the scaffold plate 6 is placed on the support bar 3, the second screw rod further comprises a screwing section 55 arranged between the first sleeve 52 and the second sleeve 53, the first sleeve 52 and the second sleeve 53 are connected through the screwing section 55, and the screwing section 55, the first sleeve 52 and the second sleeve 53 are coaxially arranged, and the cross section of the screwing section 55 is in a regular hexagon with the opposite side distance of 27mm or 30mm or 34mm or 36 mm.

When the scaffold structure is installed, an implementer inserts the second bolt 22 at the lower side into the support bar 3, enables the support bar 3 to be in threaded connection with the second bolt 22, then connects the protection bar 4 with a protection effect in a welding mode on one end, far away from the second bolt 22, of the support bar 3, enables the support bar 3 and the protection bar 4 to be in an L shape, and then sets up the telescopic connecting rod 5. When the first bolt 21 and the second bolt 22 are pre-embedded, a height difference between the two bolts may have a certain error from a preset value, which makes assembly difficult. For the convenience of connection, in the present embodiment, the first screw 51 and the first bolt 21, and the second screw 54 and the top end of the guard bar 4 are hinged, and the telescopic link 5 can adjust its axial length in a targeted manner to adapt to different height differences between the first bolt 21 and the second bolt 22. When adjusting the axial length of the telescopic link 5, an implementer only needs to screw the first sleeve 52 and the second sleeve 53 in the same rotation direction, and then the first screw 51 and the second screw 54 respectively extend out of the inner hole of the first sleeve 52 and the inner hole of the second sleeve 53, so that the whole telescopic link 5 is extended in the axial direction. After the axial length of the telescopic connecting rod 5 is adjusted adaptively and the two ends of the telescopic connecting rod are connected, the frame of a single scaffold structure is built, and then the scaffold plates 6 for constructors to walk are placed on the supporting bars 3, and the arrangement of the walkway is completed. Finally, as shown in fig. 2, other scaffold structures are repeatedly erected at the same height, and the scaffold boards 6 of the scaffold structures are connected, thereby completing the erection work of the whole building scaffold. The suspended scaffold structure saves the erection of a cantilever steel beam in the erection process, so that the construction rhythm is accelerated, and the project economic benefit is improved.

Meanwhile, as mentioned above, since the inner holes of the first sleeve 52 and the second sleeve 53 are provided with the inner threads with opposite thread turning directions, when adjusting the axial length of the telescopic link 5, an implementer only needs to screw the first sleeve 52 and the second sleeve 53 along the same rotating direction, and then the first screw 51 and the second screw 54 respectively extend out of the inner hole of the first sleeve 52 and the inner hole of the second sleeve 53, so as to extend the whole telescopic link 5 along the axial direction. In the present embodiment, in order to facilitate the operator to adjust the length of the telescopic link 5, the cross section of the screwing section 55 is a regular hexagon with an opposite edge distance of 27mm or 30mm or 34mm or 36mm, that is, the shape of the screwing section 55 is substantially consistent with that of a standard bolt head, so that the operator can rotate the screwing section 55 with a wrench during a specific screwing process to extend and retract the whole telescopic link 5. The wrench is used as auxiliary work to perform twisting operation, so that the adjusting speed is obviously improved, the adjusting speed of the axial length of the whole telescopic connecting rod 5 can be obviously accelerated, and the telescopic connecting rod has high practicability.

More specifically, in the present embodiment, the distance between opposite sides of the cross section of the screwing segment 55 is 30mm, that is, the screwing segment conforms to the shape of the head of the M20 bolt.

It should be noted that the wall 1 may be a cast-in-place member that has been cast, or a precast concrete member. In the present embodiment, the wall 1 is a precast concrete wall member. For the precast concrete wall body component, the scaffold can be assembled with the precast concrete wall body component on the ground in advance, and when the precast concrete wall body component is assembled, the scaffold can be assembled and molded together with the precast concrete wall body component, so that precious field construction time is saved, and the construction efficiency of the whole project is greatly improved.

Meanwhile, in order to reduce the force transmission link, the connection point of the first sleeve 52, the second sleeve 53 and the screwing section 55 is prevented from cracking during screwing, and as a preferred embodiment, in the present embodiment, the first sleeve 52, the second sleeve 53 and the screwing section 55 are integrally formed.

As a preferred embodiment, in order to improve the supporting reliability of the supporting bar 3, in this embodiment, as shown in fig. 1 and fig. 2, the supporting bar further includes a third bolt 23 embedded in the wall 1 and located below the second bolt 22, and a diagonal bar 7 obliquely arranged below the supporting bar 3 and capable of extending and retracting along its own axial direction, a threaded section of the third bolt 23 extends out of the wall 1, a bottom end of the diagonal bar 7 is welded to a threaded section of the third bolt 23, and a head end thereof is welded to the supporting bar 3. Wherein, wall body 1, support bar 3 and diagonal brace 7 constitute the triangle-shaped structure, can effectively improve the support effect of support bar 3 to scaffold board 6, effectively improve the security performance of whole structure.
