DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] The present invention will be further described below in conjunction with the drawings and embodiments.

[0037] Embodiment 1

[0038] In a typical embodiment of the present invention, an anchoring component for a horizontal thermal insulation decorative panel of a convex shape is proposed, as shown in Figure 1 and Figure 2As shown in the figure, it includes a first anchor 1 and a second anchor 2; the first anchor 1 includes a first horizontal plate 101 and a first vertical plate 102, and the first horizontal plate 101 and the first vertical plate 102 are vertically arranged to form an L-shaped structure; the second anchor 2 includes a second horizontal plate 201, a third horizontal plate 202 and a second vertical plate 203, the second horizontal plate 201 and the third horizontal plate 202 are parallelly arranged, and the second vertical plate 203 is vertically arranged with the second horizontal plate 201 and the third horizontal plate 202; an anchoring hole is arranged on the first vertical plate 102, and an anchoring groove 204 is arranged on the second vertical plate 203, and a bolt 4 passes through the anchoring hole and the anchoring groove 204 to connect the first anchor 1 and the second anchor 2; the left and right sides of the first anchor 1 and the second anchor 2 are inserted into a first horizontal thermal insulation decorative board and a second horizontal thermal insulation decorative board to fixedly connect them.

[0039] As Figure 2 shown in the figure, the first horizontal plate 101 of the first anchor 1 is fixed on the convex-shaped steel frame keel 5, and the convex-shaped steel frame keel 5 is fixed on the steel structure main body 6.

[0040] Furthermore, the length of the second horizontal plate 201 is greater than the length of the third horizontal plate 202, so that the connected second horizontal plate 201, third horizontal plate 202 and second vertical plate 203 form a cross-shaped structure. Considering that the second horizontal plate supports the thermal insulation layer of the thermal insulation decorative board, such as rock wool, etc., due to its large thickness, the length of the second horizontal plate is increased, and the support for rock wool is strengthened through this connecting piece, indirectly reducing the support force of the decorative layer; since the third horizontal plate supports the decorative layer of the thermal insulation decorative board, and since the decorative layer is generally thin, such as a silicate cover plate, etc., to avoid the decorative layer being slotted too long and affecting the stress of the decorative layer, the length of the second horizontal plate is set to be greater than the length of the third horizontal plate after comprehensive consideration. By arranging two layers of horizontal plates, namely the second horizontal plate and the third horizontal plate, a double insurance effect is achieved. By respectively supporting the thermal insulation layer and the decorative layer, even if there is a falling situation, under the condition of separate support, the overall detachment will not occur, and the loss and harm are minimized as much as possible.

[0041] The thermal insulation decorative board 3 generally consists of a substrate layer, a thermal insulation layer, and a decorative layer. The substrate layer generally uses a silicate cover board as the carrier of the thermal insulation layer and the decorative layer. The thermal insulation layer, as the core of the thermal insulation decorative board, generally uses rock wool, extruded board, etc. The decorative layer generally uses stone or metal plate to play a decorative role for the internal thermal insulation layer. In order to achieve the anchoring effect on the thermal insulation decorative board, a set distance is provided between the second cross plate 201 and the third cross plate 202. The second cross plate 201 and the third cross plate 202 are used to clamp the decorative layer of the thermal insulation decorative board. A step surface is provided at the position where the decorative layer of the thermal insulation decorative board is clamped with the second cross plate 201 and the third cross plate 202. The third cross plate 202 plays a supporting role for the thermal insulation decorative board; the connection position of the first anchor 1 and the second anchor 2 is located at the thermal insulation layer of the thermal insulation decorative board.

[0042] In this embodiment, a plurality of anchoring holes on the first vertical plate 102 are arranged in the vertical direction. The shape of the anchoring groove 204 on the second vertical plate 203 is a rounded rectangle. By installing bolts through the cooperation of the anchoring holes and the rounded rectangle, thermal insulation decorative boards with different thicknesses can be applied.

[0043] In this embodiment, the substrate layers at the tops of the first horizontal thermal insulation decorative board 301 and the second horizontal thermal insulation decorative board 302 are fixed on the outward convex-shaped steel frame keel 5 by bonding.

[0044] The anchoring assembly provided in this embodiment clamps two adjacent horizontal thermal insulation decorative boards through the second anchor in a cross shape, and at the same time is fixed on the outward convex-shaped steel frame keel through the first anchor to achieve the support for the horizontal thermal insulation board. In addition, the substrate layer at the top of the horizontal thermal insulation decorative board is fixed on the outward convex-shaped steel frame keel by bonding, and the anchoring effect is realized by the dual fixing methods of bottom support and top bonding for the horizontal thermal insulation board.

[0045] Embodiment 2

[0046] In a typical implementation manner of the present invention, a construction method for an outward convex shape is provided. As Figure 6 shown, using the anchoring assembly described in Embodiment 1, it includes the following steps:

[0047] Typeset the thermal insulation decorative board according to the shape of the outward convex shape and design and process the steel frame keel;

[0048] Weld the first anchor on the steel frame keel and fixedly install the steel frame keel on the steel structure main body;

[0049] Determine the position of the anchoring groove used for the second anchor according to the thickness of the thermal insulation decorative board, and install bolts to fix the first anchor and the second anchor;

[0050] Insert the first horizontal thermal insulation decorative board into the second anchor for preliminary fixation;

[0051] Use a horizontal measuring instrument to assist in positioning, and precisely adjust the flatness of the horizontal thermal insulation decorative board up and down;

[0052] After the flatness adjustment is completed, bond the substrate layer of the thermal insulation decorative board to the steel frame keel with structural adhesive;

[0053] Check the horizontality and verticality of the thermal insulation decorative board, and complete the anchoring and bonding of a single board;

[0054] Install the remaining thermal insulation decorative boards in sequence to complete the installation of the thermal insulation decorative boards.

[0055] Furthermore, the spacing of the steel frame keels is determined according to the layout of the thermal insulation decorative boards to ensure that there are steel frames at the joints of the thermal insulation decorative boards and they are centered.

[0056] Furthermore, the number of bonding points between each thermal insulation decorative board and the steel frame keel is not less than four.

[0057] Furthermore, after the installation of the thermal insulation decorative boards is completed, fill with caulking materials and apply sealant to form an Figure 3 outward convex shape as shown.

[0058] During the construction of the above-mentioned outward convex shape construction method, weld and assemble the steel frame keels of the outward convex shape on the ground, and install the whole on the outside of the main structure steel beam of the main body through angle steel; the spacing of the steel frames is determined according to the layout of the thermal insulation decorative boards to ensure that there are steel frames at the joints of the thermal insulation decorative boards and they are centered, and weld the first anchor on the steel frame in advance on the ground, saving high-altitude construction steps, reducing construction risks, and saving construction time.

[0059] The construction method of the outward convex shape provided in this embodiment uses steel frame keels to be fixed on the main structure of the steel building. Compared with the existing concrete cantilever slab, there is no need for pouring, and no external scaffolding is required, saving a large amount of measure fees; by using steel frame keels to be fixed on the main structure, as Figure 4 and Figure 5 shown, compared with the existing concrete cantilever slab, by replacing the surface connection (the contact area between the concrete cantilever slab and the steel structure main body) of the concrete cantilever slab 7 with point connection (the contact area between the angle steel and the steel structure main body), the area of the heat bridge connection position 8 is reduced, and no heat bridge can be achieved by fully covering the thermal insulation decorative board, which is the best heat bridge-free practice for matching nearly zero-energy consumption steel structure buildings; in addition, the main structure of the steel building and the steel frame keels of the outward convex shape use the same material, and by utilizing the characteristics of the light weight and consistent deformation of the steel frame, the deformation of the shaped steel frame and the main body is made consistent, better playing the characteristics of the steel structure building in the construction of the shaping method of the prefabricated steel structure building, improving the construction speed and strengthening the construction quality.

[0060] Although the specific implementation manners of the present invention are described above in conjunction with the accompanying drawings, it is not a limitation on the protection scope of the present invention. Those skilled in the art should understand that various modifications or deformations that can be made without creative efforts on the basis of the technical solutions of the present invention are still within the protection scope of the present invention.
