A steel scaffold board and a skirting steel board may be installed in each layer.
The upright posts 1 are arranged in three rows from inside to outside from the decorative vertical surface of the curtain wall, one row close to the decorative vertical surface of the curtain wall is an inner-layer upright post, and the other two rows are outer-layer upright posts. Inlayer pole setting 1 constitutes the inlayer construction support body with horizontal pole 3 and vertical pole 2, outer pole setting 1 with horizontal pole 3 and vertical pole 2 constitute outer construction support body, and wherein every horizontal pole is formed by being connected of an inlayer horizontal pole and an outer horizontal pole. The outer uprights are all vertical uprights perpendicular to the ground and the inner uprights comprise a lower vertical upright and an upper diagonal upright 5 (as shown in figures 4a and 4 b).
As shown in fig. 6, the diagonal uprights 5 are at the level of the curtain wall trim panel to be installed and at an angle of inclination corresponding to the angle of inclination of said curtain wall trim panel to be installed. Along with the installation progress of the curtain wall decorative plate, the inclined upright post 5 positioned above can be detached, and the vertical upright post 1 positioned below can be adjusted into the inclined upright post 5, so that the height of the inclined upright post gradually moves downwards; and the inner layer cross bars corresponding to the inclined vertical rods can be transversely displaced correspondingly so as to be adjusted to be suitable for mounting the inner layer construction prosthesis of the curtain wall decorative plate.
In the inner layer upright rod 1, the installation nodes of the inclined upright rod and the vertical upright rod are positioned between the upper layer cross rod and the lower layer cross rod. As shown in fig. 4a and 4b, the upper end of the inner uprights 1 is positioned above the remaining cross-bar, but below the curtain wall to be installed, when adjusted for removal.
As can be seen from fig. 4a and 4b, the inner layer cross bar 3 and the outer layer cross bar 3 are two short cross bars, and the inner layer cross bar and the outer layer cross bar are not communicated, and the inner layer cross bar 3 is lapped on the outer layer cross bar. The outer layer cross rod is fixed after being installed, and the inner layer cross rod moves along with the change of the vertical rod of the inner layer according to the change of the inclined plane of the curtain wall and then is fixed. In one embodiment, the mounting height of the inner layer cross bar is 6-8 mm higher than the outer layer cross bar, but the invention is not limited thereto.
Set up adjustable string knot formula scaffold board in the inlayer support body, the spatial position that changes from curtain fossil fragments begins in the installation, provides spatial position after adjusting by the adjustable scaffold board of instrument formula of inlayer until the installation of curtain panel. The materials, tools and personnel traffic of the construction stage are basically provided by the outer layer scaffold.
As shown in FIG. 3 and FIG. 3a, the present invention is provided with a fire window frame W between the decorative vertical surfaces of the curtain wall, and a buttress body 11 is further provided at the outer side position. The buttress body also comprises a plurality of layers, and each layer comprises a vertical rod 1, a cross rod 3 and a longitudinal rod 2 which are shared by the inner-layer construction body and the outer-layer construction body. And an additional upright rod 1a and an additional cross rod 3a are arranged at the position of a structural wall body in the fire-fighting window frame in a clinging manner. The horizontal pole of sharing is logical long double cross pole 3, lead to long double cross pole 3 and extend and get into the fire control window frame, additional horizontal pole 3a links to each other with logical long double cross pole 3 and forms the buttress support body of drawknot, and every buttress support body adds the back at its facade, forms stable spatial structure (as shown in fig. 5), and its intensity and stability have fully satisfied the height that the curtain wall (through setting up the electronic or chain block 7 on buttress support body top) promoted and the whole loads of promotion.
The special-shaped multifunctional scaffold has the following characteristics:
(1) the double-deck special-shaped scaffold frame body of three pole settings, the location of its pole setting step, stride satisfies the installation of the fossil fragments of curtain installation and surface course aluminum plate space transform: this scaffold design three poles, form inside and outside double-deck construction support body: the inner scaffold can be used for the construction of curtain fossil fragments installation, and the overall stability when outer scaffold is used for the support body repacking when curtain installation and special-shaped change to the effect that provides the hoisting frame of curtain material.
Namely, on the premise of meeting the safety: 1) the frame body is designed to be a double-layer outer layer which is a passage for temporarily storing and installing personnel, and an inner layer which is special-shaped and can be changed to meet the requirement of multiple functions; 2) the double-layer scaffold must meet the requirement of installing keels of the curtain wall firstly; 3) in the installation stage of the curtain wall decoration panel, the design of the upright posts and the cross bars of the inner layer of the scaffold needs to meet the curtain wall construction with vertical face change, namely the inner layer of the scaffold corresponding to the installation height of the curtain wall, and the upright posts are adjusted to be inclined upright posts from vertical upright posts to form an inclined cross section scaffold body; the inner layer scaffold cross bar is provided with a cross bar again according to the inclined vertical bar and is provided with a novel combined and shaped construction scaffold steel net rack, namely a safety railing; 4) the vertical rods in the inner-layer scaffold of the scaffold are installed according to the designed height of the decorative vertical surface of the curtain wall, the vertical rods are partially dismantled from top to bottom according to the installation height of the curtain wall, and the installation cross rods, the inner-layer scaffold step plates and the safety rails are adjusted to enable the scaffold body with the inclined cross section to be parallel to the curtain wall; 5) the fire-fighting window frame is an interface between the decorative and variable vertical surfaces of the curtain wall, namely the installation changes of the inner vertical rod, the outer vertical rod, the cross rod and the safety measure of the scaffold are all bounded by the fire-fighting window of the vertical surface of the building; 6) this buttress support body that double-deck scaffold set up, for the logical long double cross pole of inside and outside double-deck scaffold of intercommunication, the fire window frame is deepened to the double cross pole, and the horizontal pole and the pole setting drawknot that hug closely with the structure wall body form the buttress support body of drawknot. The invention is suitable for the conditions that the variable cross-section inclined plane of the engineering decorative curtain wall is outwards selected and staggered in sections, and a hanging basket cannot be used, and the double-layer special-shaped multifunctional scaffold can provide the following requirements: the installation and construction of the curtain wall on the inclined plane exterior cantilever curtain wall between the section (block) with large top and small bottom and the section (block) with large top and small bottom on the building vertical surface are met.
