Description

[Technical Field]

[0001] The present invention relates to a waist wall decorative cover, and more particularly to a waist wall decorative cover that can be easily fixed by simply inserting it into the gap between a waist wall and a furring strip, thereby improving the finish of a steel frame structure. [Background technology]

[0002] Steel-frame structures (S-frame construction) that can secure large spaces with steel columns and beams are used in large structures such as logistics warehouses and factories. The exterior walls of steel-frame structures are constructed by (1) constructing a foundation by building a formwork on the site and pouring concrete, (2) backfilling the base of the foundation, (3) erecting the steel frame, (4) building a formwork on the foundation and pouring concrete to build a spandrel wall, (5) fixing furring strips to the steel frame, and (6) attaching exterior wall materials to the furring strips (Patent Document 1). Normally, there is a gap between the waist wall and the steel frame, but in designs where the waist wall and steel frame are close together, it is not possible to install formwork between them, so the formwork for the waist wall is sometimes extended to the side of the steel frame and a concrete retaining wall is installed between the waist wall and the steel frame. The top of the spandrel wall is covered by the lowest furring strip, but the buttress part is separated from the furring strip and the top is exposed. Also, there may be a gap between the spandrel wall and the furring strip to accommodate construction errors. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-303676 Summary of the Invention [Problem to be solved by the invention]

[0004] The conventional technology has the following problems. <1> The concrete surface of the upper part of the buttress is exposed to the outside, which results in an unattractive finish. In addition, if water accumulates on the top of the buttress, it can seep into the concrete, causing deterioration of the entire buttress. <2> The gaps between the waist wall and the furring strips also look unsightly, and dirt and dust accumulate in the gaps, making maintenance time-consuming and costly. While the gaps can be filled with mortar, this is a labor-intensive process and there is a risk that the mortar will stain the waist wall and furring strips.

[0005] SUMMARY OF THE INVENTION An object of the present invention is to provide a waist wall decorative cover that solves the above-mentioned problems of the prior art. [Means for solving the problem]

[0006] The waist wall decorative cover of the present invention comprises a covering plate having a rectangular top plate portion and two side plate portions extending from both widthwise sides of the top plate portion, and an elastic support plate having an extension portion extending horizontally from one longitudinal side of the top plate portion and a folded portion formed by folding the tip side of the extension portion diagonally downward from the extension portion, and is characterized in that when the elastic support plate is inserted between the waist wall and the furring strip, with the top plate portion covering the top surface of the buttress and the two side plate portions covering the upper sides of the buttress, the elastic support plate can be pressed against the waist wall and the furring strip to fix them in place by the shape elasticity of the folded portion against the extending portion.

[0007] The waist wall decorative cover of the present invention may be configured so that the two side panel portions can be bent downward from a state where they are flush with the top panel portion, and by bending the two side panel portions downward at approximately 90 degrees, the upper side of the buttress can be covered.

[0008] The waist wall decorative cover of the present invention comprises a covering plate, an elastic support plate, and a concealing plate that is a separate member, and the concealing plate comprises a rectangular covering portion extending vertically and an elastic support portion formed by folding the tip extending horizontally from the upper edge of the covering portion diagonally downward, and when the elastic support portion is inserted between the waist wall and the furring strip, the covering portion can cover the upper part of the waist wall along the longitudinal direction of the waist wall. [Effects of the Invention]

[0009] The waist wall decorative cover of the present invention has at least one of the following effects due to the above-mentioned structure. <1> By covering the upper part of the retaining part of the spandrel wall, the appearance of the finished product can be improved and deterioration of the concrete due to stagnation of moisture can be prevented. <2> It can be easily attached to the waist wall by simply inserting the elastic support plate into the gap. <3> When a privacy panel is installed, it can seal the gap between the waist wall and the furring strip, improving the appearance and preventing the intrusion of dirt and dust. [Brief explanation of the drawings]

[0010] [Figure 1] Illustration of the decorative covering for the lower wall [Figure 2] Diagram of a steel structure [Figure 3] How to use the waist wall decorative cover [Figure 4] Explanatory diagram of Example 2 DETAILED DESCRIPTION OF THE INVENTION

[0011] The following describes the details of the spandrel decorative cover of the present invention with reference to the drawings. In the present invention, the terms "up," "down," "front," "back," "side," "height," and "width" refer to the directions of the spandrel decorative cover when it is attached to the buttress of the spandrel wall and facing the exterior of the steel frame structure from the indoor side. [Example]

[0012] <1> Wainwall decorative cover (Figure 1) The spandrel decorative cover 1 of the present invention is a member for partially covering the buttress B1 of the steel structure A to improve the appearance of the finish and prevent deterioration of the spandrel wall B. The waist wall decorative cover 1 comprises at least a covering plate 10 that covers the buttress B1, and an elastic support plate 20 that is integral with the covering plate 10. One feature of the waist wall decorative cover 1 is that it covers the buttress B1 with a covering plate 10 and can be fixed in the gap G between the waist wall B and the furring strip C by the shape elasticity of the elastic support plate 20. In this example, a bent stainless steel plate is used as the waist wall decorative cover 1. However, the waist wall decorative cover 1 is not limited to this, and may be made of aluminum alloy, polyester resin, melamine resin, glass fiber resin, or the like.

[0013] <1.1> Steel structure (Fig. 2) The steel structure A comprises at least a steel frame D erected on a foundation, a waist wall B erected on the outdoor side of the steel frame D, and a long furring strip C arranged above the waist wall B. The spandrel wall B is connected to the exterior side of the steel frame D by the rear buttress B1. The furring strip C is fixed to the exterior side of the steel frame D. The furring strips C extend along the longitudinal direction of the waist wall B, and a gap G is formed between the waist wall B and the lowest furring strip C.

[0014] <2> Covering board The covering plate 10 is a component that covers the upper part of the buttress B1. The cover plate 10 includes at least a rectangular top plate portion 11 and two side plate portions 12 extending from both sides of the top plate portion 11 in the width direction. The width and depth of the top panel portion 11 correspond to the width and depth of the buttress B1. The cover plate 10 may be flat when stored, but when in use, the two side plate portions 12 are bent downward by 90 degrees to form a generally inverted U-shape when viewed from the front.

[0015] <3> Elastic bearing plate The elastic support plate 20 is a component that is fixed to the waist wall B. The elastic support plate 20 has a generally V-shape in side view and includes an extending portion 21 and a folded portion 22 formed by folding back the tip of the extending portion 21, and the folded portion 22 has shape elasticity relative to the extending portion 21. The extension 21 extends horizontally from the longitudinal direction of the top plate portion 11 of the cover plate 10 . The folded-back portion 22 folds back the tip side of the extending portion 21 downward from the extending portion 21 and extends obliquely downward toward the covering plate 10 side. By extending the folded portion 22 downward instead of upward from the extending portion 21, when the furring strip C is made of a channel material, the folded portion 22 can be prevented from penetrating into the interior of the furring strip C and hindering elastic deformation.

[0016] <4> How to use the waist wall decorative cover (Figure 3) The waist wall decorative cover 1 of the present invention is used, for example, as follows. The flat waist wall decorative cover 1 is placed from the inside of the room toward the vicinity of the buttress B1 of the waist wall B, and an elastic support plate 20 is inserted into the gap G between the waist wall B and the furring strip C (Fig. 3(a)). Once the entire length of the elastic support plate 20 is within the gap G, it is slid sideways along the spandrel wall B, and the covering plate 10 is moved onto the buttress B1. The top plate portion 11 of the covering plate 10 is aligned with the upper surface of the buttress B1, and the two side plate portions 12 are bent downward by 90 degrees to cover the upper side surface of the buttress B1 (FIG. 3(b)). By the above work, the top plate portion 11 and the two side plate portions 12 cover the top surface and upper side of the buttress B1, and the shape elasticity of the folded portion 22 relative to the extension portion 21 allows the covering plate 10 to be securely positioned in the gap G between the waist wall B and the furring strip C. [Example]

[0017] [Example with a blindfold] In this example, the waist wall decorative cover 1 further comprises a cover plate 10, an elastic support plate 20, and a blind plate 30 which is a separate member (FIG. 4). The privacy panel 30 is not a buttress B1 but is a long member that covers the main body of the waist wall B, and is equipped with at least a rectangular covering portion 31 that covers the upper part of the waist wall B and an elastic support portion 32 that is fixed to the waist wall B. The covering portion 31 has a rectangular shape that is long in the width direction. It is desirable that the height of the covering portion 31 coincide with the height of the side plate portion 12 of the covering board 10. This improves the sense of unity of the design from the spandrel wall B to the buttress B1. The elastic support portion 32 is formed by folding back the tip of the horizontally extending portion from the upper side of the covering portion 31 obliquely downward. The structure and function are the same as those of the elastic support plate 20. In this example, by closing the gap between the waist wall B and the furring strip C with the blind board 30, the appearance of the finished waist wall B can be improved and dirt and the like can be prevented from accumulating in the gap.
