[0041] The following will be combined with the Figures 1-3 The present application is further described in detail.

[0042] The embodiment of the present application discloses a curved structure outer side scaffold foot point connecting structure. Referring to Figure 1 , the curved structure outer side scaffold foot point connecting structure comprises a connecting body 1 and a longitudinal tie member 2 fixed on the connecting body 1. The connecting body 1 is used for connecting and fixing with the counter-bolt reserved in the fair-faced concrete outer wall 02 itself, and the longitudinal tie member 2 is used for realizing the pull connection between the adjacent two connecting bodies 1, and combining the adjacent two bodies into an integrated type.

[0043] Referring to Figure 1 and Figure 2The connecting body 1 comprises an inclined surface 11 which is in close contact with the curved surface of the exposed cast-in-place concrete wall 02, a lapping surface 12 which is fixed to the inclined surface 11 and is parallel to the horizontal plane, and a reinforcing edge rib 13 which is connected between the inclined surface 11 and the lapping surface 12. The reinforcing edge rib 13 is fixed to both sides of the inclined surface 11, and the reinforcing edge rib 13 is triangular to realize the connection between the side of the lapping surface 12 and the top corner of the inclined surface 11. Preferably, the connecting body 1 of the present application is made by one-piece forming. The inclined surface 11 is provided with a mounting hole 111 for connecting with the reserved anchor bolt. During installation, the anchor bolt reserved during pouring of the exposed cast-in-place concrete is passed through the mounting hole 111 of the inclined surface 11, and the inclined surface 11 is in close contact with the exposed cast-in-place concrete wall 02. Then, a nut 3 is screwed to the end of the anchor bolt to realize the fixation of the connecting body 1 on the exposed cast-in-place concrete wall 02. The exposed cast-in-place concrete wall 02 is fixed without additional embedded connecting parts, but only by using the reserved anchor bolt, so that the appearance of the exposed cast-in-place concrete wall 02 is not damaged. After the connecting body 1 is fixed, the lapping surface 12 which is parallel to the horizontal plane becomes a support landing point for fixing the column, and realizes the temporary fixation of the column on the horizontal plane. The force point of the column is directly transferred from the ground of the traditional scaffold to the exposed cast-in-place concrete wall 02, so that the fixation of the column is more stable, the column is less likely to be tilted, and the column is provided with multiple connection structures which are in close contact with the curvature of the wall surface, so that the scaffold is also set according to the shape of the exposed cast-in-place concrete wall 02. The distance between the scaffold and the exposed cast-in-place concrete wall 02 is constant, which is convenient for the construction of the construction personnel.

[0044] With reference to Figure 2 In order to limit the horizontal displacement of the column on the lapping surface 12, and facilitate the installation and fixation of the column, the upper surface of the lapping surface 12 is provided with a limiting sleeve 14 or a limiting groove for limiting the horizontal displacement of the column. When the limiting sleeve 14 is fixed on the lapping surface 12, the limiting sleeve 14 is processed to match the size of the column, so that the inner diameter of the limiting sleeve 14 is consistent with the outer diameter of the column. When the column is installed, the end of the column is directly inserted into the limiting sleeve 14. In order to ensure the firm installation of the column, the height of the limiting sleeve 14 is not less than 10 cm, and a clamping part or other fixing part can be selectively used to further fix the column. When the limiting groove is provided on the lapping surface 12, the column is directly inserted into the limiting groove and is welded and fixed.

[0045] With reference to Figure 1 The longitudinal tie 2 makes the adjacent two connection structures integrated, which can enhance the stress and improve the supporting performance of the connecting body 1, so that the construction of the scaffold is more stable. Even if the anchor bolt is broken, the tie force of the longitudinal tie 2 can also be used to delay the collapse time of the scaffold, so as to reserve a certain maintenance time for the construction personnel. The length of the longitudinal tie 2 is about 0.5-1.5 cm less than the distance between the adjacent two connecting bodies 1.

[0046] In principle, the longitudinal tie 2 can be tied with the upper connection body 1 or the lower connection body 1, but in order to facilitate the gradual tie of the longitudinal tie 2 with the installation of the connection body 1 from bottom to top, and ensure the smooth construction process, the longitudinal tie 2 is tied and fixed with the connection body 1 of the upper level (only the upper level in the height direction, and the actual construction is the level built later). Specifically, the longitudinal tie 2 is fixed on the inclined surface 11 and extends, and the distal end of the longitudinal tie 2 is used to be sleeved on the opposite pull bolt of the upper level. When the upper connection body 1 is installed, the end of the opposite pull bolt is first inserted into the installation hole 111, and then the longitudinal tie 2 of the upper connection structure is tied, and after the distal end of the longitudinal tie 2 is sleeved on the opposite pull bolt, the fixing nut 3 is screwed, and the installation of the upper connection body 1 is completed. The longitudinal tie 2 is sleeved on the opposite pull bolt of the upper level, which facilitates the tie of the longitudinal tie 2, and also reduces the probability of fracture of the opposite pull bolt and improves the support stability of the connection structure.

[0047] In order to deform the longitudinal tie 2 to fit the fair-faced concrete outer wall 02 according to the curvature of the fair-faced concrete outer wall 02, the longitudinal tie 2 is a flexible plate 21 made of flexible material, and the distal end of the flexible plate 21 is provided with a tie hole for the opposite pull bolt to pass through. The present application takes an iron sheet of 2-3 mm as an example. Since the iron sheet itself has a certain ductility, the tie force between the adjacent two levels of connection bodies 1 can be guaranteed during the tie. Further, in order to improve the deformation ability and ductility of the flexible plate 21, on the basis of calculation to guarantee the tie force of the flexible plate 21, a weight-reducing hole 211 extending along the length direction of the flexible plate 21 can also be provided on the flexible plate 21, and the rigidity of the flexible plate 21 is further reduced, which is more convenient for deformation and stretching.

[0048] In order to further reduce the probability of bumping and wearing of the fair-faced concrete outer wall 02 and guarantee the appearance performance of the fair-faced concrete outer wall 02, a combined / split gasket (not shown in the figure) is arranged between the inclined surface 11 and the fair-faced concrete outer wall 02, and the gasket is provided with an insertion hole penetrating the installation hole 111. The gasket is made of polyurethane plastic, resin, rubber and other materials with certain supporting and toughness, and can be a separate gasket (i.e. a split gasket) or a combined gasket directly fixed to the back side of the inclined surface 11.

[0049] The implementation principle of the foot point connecting structure of the curved structure outer side scaffold is as follows: when the scaffold is built, the connecting structure is built from bottom to top. Taking the building of the connecting structures of two adjacent levels as an example, the lower level connecting main body 1 is first fixed with the opposite pulling bolt by using the nut 3, then the upper level connecting main body 1 is installed, the opposite pulling bolt is first arranged in the installation hole 111, and is not fixed temporarily, then the longitudinal pulling member 2 of the lower level is longitudinally stretched and is pulled with the opposite pulling bolt of the upper level, so that the opposite pulling bolt passes through the pulling hole at the end of the longitudinal pulling member 2, the curvature of the longitudinal pulling member 2 is adjusted to be fitted with the exposed aggregate concrete outer wall 02. Finally, the nut 3 of the upper level opposite pulling bolt is fixed. Then the connecting structure is installed step by step upwards, after the completion of the connecting structure, the vertical column is fixed on the lap joint surface 12 in sequence, and the horizontal rod arranged horizontally with the vertical column is fixed in sequence by using the special connecting member, until the scaffold is built. After the completion of the scaffold, the scaffold is also fitted with the exposed aggregate concrete outer wall 02, that is, the distance between the scaffold and the exposed aggregate concrete outer wall 02 is constant, which is convenient for the construction of the construction personnel.

[0050] The application also discloses a foot point building method of the curved structure outer side scaffold. Figure 3 The foot point building method of the curved structure outer side scaffold comprises the following steps.

[0051] S1: installing the first level connecting main body 1: connecting the connecting main body 1 with the opposite pulling bolt, and fixing by using the nut 3, to create the vertical column foot point.

[0052] S2: installing the second level connecting main body 1: the end of the opposite pulling bolt passes through the installation hole 111 of the inclined surface 11.

[0053] S3: pulling of the connecting structures of two adjacent levels: the end of the longitudinal pulling member 2 is sleeved on the second level opposite pulling bolt. Specifically, when the longitudinal pulling member 2 is pulled, the longitudinal pulling member 2 is adjusted according to the curvature of the exposed aggregate concrete outer wall 02, so that the longitudinal pulling member 2 is pulled according to the set tension.

[0054] S4: fixing of the second level connecting main body 1: the nut 3 is screwed on the second level opposite pulling bolt, and the longitudinal pulling member 2 is fixed integrally with the second level connecting main body 1.

[0055] S5: repeating the above steps to install the connecting structure from bottom to top in sequence, and the vertical column foot point is created.

[0056] S6: building the scaffold in sequence: the vertical column is fixed with the limiting sleeve 14 or the limiting groove in sequence, and the scaffold horizontal rod is built according to the set construction procedure.

[0057] In order to further reduce the probability of scratch and wear on the surface of the fair-faced concrete outer wall 02, and to protect the appearance of the fair-faced concrete outer wall 02, before the installation of the connecting body 1, a gasket with an arc is selected according to the curvature of the fair-faced concrete outer wall 02, and is arranged between the inclined surface 11 and the fair-faced concrete outer wall 02.

[0058] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
