DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present utility model will be further described below in conjunction with specific embodiments, but the protection scope of the present utility model is not limited thereto.

[0024] As Figures 1-8 shown, the large-span wall system with hidden keels of the present utility model includes a ribbed composite board 1. Adjustment members 2 are provided on both sides of the ribbed composite board 1. A water guide plate 3 is provided on the adjustment member 2. A plug 4 is provided on the side of the ribbed composite board 1. The plug 4 is a foam plug. The plug 4, the water guide plate 3 and the adjustment member 2 are all fixed to the steel column flange by structural nails 5.

[0025] The adjustment member 2 in the present utility model is in a shape of "Ji", and is used as a conversion part for connecting the composite wall panel and the steel column. If the composite wall panel is directly fixed to the steel column flange with nails, it will be difficult for the nails to penetrate due to the thickness of the flange. Moreover, if the outer surface of the steel column flange is uneven, the flatness can be finely adjusted through the intermediate adjustment member 2 to ensure the overall flatness of the wall.

[0026] A window 6 is provided in the middle of the ribbed composite board 1. The periphery of the window 6 is a keel composite board. The periphery of the keel 7 is trimmed by a trimming member. The keel composite board and the trimming member are fixed by rivets 8. The trimming member and the window 6 are sealed by a sealant 9.

[0027] The trimming member includes a horizontal trimming member and a vertical trimming member. The horizontal trimming member includes a first horizontal trimming member 10, a second horizontal trimming member 11 and a third horizontal trimming member 12. The vertical trimming member includes a first vertical trimming member 13 and a second vertical trimming member 14.

[0028] A construction method for the large-span wall system with hidden keels of the present utility model includes the following steps:

[0029] (1) Determine the wall panel thickness. According to the natural conditions of the project location, check the bearing capacity of the wall panel. If the specification requirements cannot be met, add wind-resistant columns. The construction method of the wind-resistant columns is the same as the conventional one.

[0030] (2) According to the column spacing, window height and wind load, determine the cross-sectional thickness of the keel 7. At the same time, according to the window opening size, design the placement position of the keel in the wall panel to ensure sufficient space for window installation;

[0031] (3) After determining the column spacing, select the specification size and laying direction of the ribbed composite board 1. The rib spacing of the ribbed composite board 1 is 250 mm - 400 mm, and the total thickness of the board is 100 mm - 200 mm.

[0032] (4) Deeply layout the ribbed composite board 1 in advance to determine the number of the ribbed composite board 1, the number of the keel composite boards and the installation positions.

[0033] (5)During on-site construction, the adjustment member 2 is arranged in the axial direction of the steel column. First, the adjustment member 2 is connected and fixed to the steel column, and then the water guide plate 3 and the ribbed composite plate 1 are sequentially laid on the upper surface of the adjustment member 2. After determining the position, on each rib, the ribbed composite plate 1 and the adjustment member 2 are connected together with the structural nails 5 and fixed to the steel column flange to form a combined stress system to ensure the overall stability.

[0034] (6)The foam plugs 4 are pre-bonded to the ribbed composite plate 1 in the factory.

[0035] (7)The window openings are cut on the keel composite plate prefabricated in the factory.

[0036] (8)After cutting, the transverse edge trimmer and the vertical edge trimmer are used to protect the cut of the keel 7. The installation method of the plate is the same as that of the ribbed composite plate 1.

[0037] In the present utility model, considering the structural stress and economy, the keel 7 can be made of rectangular tubes, C-shaped purlins, etc., and the materials can be selected from carbon steel, aluminum alloy. The ribbed composite plate 1 is composed of a galvanized metal bottom plate, thermal insulation cotton, a galvanized metal panel, etc. The total thickness of the rib height and the plate surface is controlled within 100 mm - 200 mm, such as 100 mm, 200 mm, 150 mm, etc. The shape of the ribs of the ribbed composite plate 1 is not restricted, and it can be of equal width or unequal width, but the rib width matches the height of the keel, and the center distance between the ribs is controlled within 250 mm - 400 mm, such as 250 mm, 400 mm, 325 mm, etc. The length of the structural nail 5 is not less than "the total thickness of the composite plate + the height of the adjustment member + 10 mm". Along the height direction of the steel column, one structural nail 5 is arranged on each rib and at the opening.

[0038] The present utility model can save the procurement cycle and processing cycle, realize the unitized installation of window walls, simplify the construction process, shorten the construction cycle, reduce the cost, and ensure the indoor beauty and coordination.

[0039] The above embodiments are only used to explain the inventive concept of the present utility model, rather than limiting the protection scope of the rights of the present utility model. Any non-substantive modification made to the present utility model using this concept shall fall within the protection scope of the present utility model.
