Description

Technical Field

[0001] The utility model relates to the technical field of concrete construction, and particularly relates to a decorative chamfer strip for fair-faced concrete construction. Background Art

[0002] Fair-faced concrete is a kind of concrete that directly uses the natural texture after the concrete is formed as the finishing effect. Fair-faced concrete slabs are a common building material, widely used in fields such as building structures, basements and underground structures, pools and aquariums, transportation infrastructure, industrial facilities, and agricultural buildings. Its high strength and durability make it an ideal choice for load-bearing structures, and at the same time, its good waterproof performance also makes it widely used in basements, pools and other occasions. In terms of building decoration, fair-faced concrete endows the building with unique artistic charm with its natural and simple texture. Without additional decoration on its surface, it can display the texture and color of the concrete itself, making the building appearance more concise and grand. At the same time, fair-faced concrete can also imitate the texture of other materials, such as stone imitation, wood imitation, etc., increasing the diversity and flexibility of its design.

[0003] During the construction process of fair-faced concrete, in order to enhance the visual effect and layering of the building, chamfer strips are usually used for decoration at the right-angle parts of the structure. Through the design of the chamfer lines, the right-angle parts become more gentle, reducing the stiffness, and at the same time increasing the three-dimensional sense and dynamic sense of the building. The design of the chamfer lines can make this decoration method not only conform to the modern architectural design concept of simplicity and fashion, but also improve the overall aesthetics of the building. The existing chamfer strips are as Figure 1 shown. When this kind of chamfer strip is used, since a closed space cannot be formed between the template and the chamfer strip, there is a problem of easy mortar leakage at the joints during the actual construction process. Summary of the Utility Model

[0004] The technical problem solved by the utility model is that there is a problem of easy mortar leakage at the joints during the actual construction process of the existing chamfer strips.

[0005] The purpose of the utility model can be achieved by the following technical solutions:

[0006] A decorative chamfer strip for fair-faced concrete construction, comprising a chamfer strip main body. Two grooves are formed in the chamfer strip main body, and the sides of the two grooves are vertically arranged. The shape of the groove matches the shape of the template.

[0007] In one aspect of the utility model: The chamfer strip main body includes an outer main body and an inner main body. The outer main body and the inner main body are fixedly connected through a partition part. The groove is formed by enclosing the outer main body, the inner main body and the partition part.

[0008] In one embodiment of the present utility model: Two adjacent faces on the outside of the external main body are perpendicularly arranged.

[0009] In one embodiment of the present utility model: The side of the internal main body away from the external main body has a rounded corner transition.

[0010] In one embodiment of the present utility model: The cross-section of the groove is a rectangular structure.

[0011] In one embodiment of the present utility model: The end of one groove is flush with the outer side of the other groove.

[0012] In one embodiment of the present utility model: The cross-section of the groove is a right trapezoidal structure.

[0013] In one embodiment of the present utility model: The two grooves are symmetrically arranged on both sides of the partition part.

[0014] According to a decorative chamfering strip for fair-faced concrete construction of the present utility model, it has at least one of the following technical effects:

[0015] In this application, by opening two grooves matching the shape of the template at both ends of the corner strip main body, the template can be directly inserted into the grooves of the corner strip during use. The corner strip main body serves as a connecting piece to connect the four side templates into a whole, eliminating the need for additional components for corner reinforcement work. Since the connection between the corner strip main body and the template is a closed connection, it can effectively prevent slurry leakage and solve the problem of easy slurry leakage at the connection in the prior art. When constructing the chamfering strip in this application, the direct plug-in method is adopted, which not only improves the installation efficiency of the template but also avoids waste of the template. After the template is inserted into the groove, under the restriction of the corner strip main body, the ends of the two templates can form a certain mutual support, thereby enhancing the strength of the connection position and reducing the risk of chamfering strip deformation.

[0029] Existing chamfer strips such as Figure 1As shown in the figure, it includes an angle bar main body 10. When in use, one side surface of the angle bar main body 10 is attached to one formwork 20, and an open notch is provided on the other side surface to cooperate with another formwork 20. A wooden square 30 or other structures are used to fix it on the outside of the other formwork 20. When using this chamfering bar, since a closed space cannot be formed between the formwork 20 and the chamfering bar, there is a problem that slurry is likely to leak at the connection during the actual construction process. One formwork 20 extends beyond the other formwork 20 by a relatively long length, resulting in waste of the formwork 20. Moreover, the other formwork 20 lacks support, resulting in insufficient strength at the chamfering position and prone to deformation. And when using this kind of chamfering bar, additional structures need to be used for auxiliary fixing construction. To improve this kind of chamfering line, this application proposes a decorative chamfering bar for fair-faced concrete construction.

[0030] Please refer to Figures 2 - 5 , the utility model is a decorative chamfering bar for fair-faced concrete construction, including an angle bar main body 10. Two grooves 100 are opened at both ends of the angle bar main body 10. The angle bar main body 10 includes two intersecting parts. The two grooves 100 are respectively arranged at the outer ends of the two parts. The sides of the two grooves 100 are vertically arranged, that is, the plane where the side of one groove 100 is located is vertically arranged with the plane where the side of the other groove 100 is located, so that the two grooves 100 form a vertical layout. The shape of the groove 100 matches the shape of the formwork 20. When in use, the formwork 20 can be directly inserted into the groove 100, and the angle bar main body 10 is used as a connecting piece to connect the four side formworks 20 into a whole.

[0031] Please refer to Figures 2 - 5 , in one embodiment of the utility model, the angle bar main body 10 may include an outer main body 101 and an inner main body 102. The outer main body 101 and the inner main body 102 are fixedly connected through a partition 103. The outer main body 101, the inner main body 102 and the partition 103 may be an integral structure. The groove 100 is formed by enclosing the outer main body 101, the inner main body 102 and the partition 103. Two adjacent surfaces outside the outer main body 101 are vertically arranged. The side of the inner main body 102 away from the outer main body 101 is rounded.

[0032] Please refer to Figures 2 - 5 , in one embodiment of the utility model, the specific shape of the groove 100 can be designed according to the assembly method of the formwork 20; one embodiment is as Figure 2 , the groove 100 is a rectangular structure. The end of one groove 100 is flush with the outer side of the other groove 100. Another embodiment is as Figure 4, the groove 100 is a right trapezoidal structure. The two grooves 100 are symmetrically arranged on both sides of the partition portion 103. In the structure with these two groove arrangements, after the template 20 is inserted into the groove 100, under the restriction of the corner strip body 10, the ends of the two templates 20 can form a certain mutual support, thereby improving the strength of the connection position and reducing the risk of chamfer strip deformation.

[0033] The working principle of the present utility model:

[0034] In this application, two grooves 100 matching the shape of the template 20 are opened at both ends of the corner strip body 10. During use, the template 20 can be directly inserted into the corner strip groove 100. The corner strip body 10 serves as a connecting member to connect the four side templates 20 into a whole, without the need to use additional components for corner reinforcement work. Since the connection between the corner strip body 10 and the template 20 is a closed connection, it can effectively avoid mortar leakage and solve the problem of easy mortar leakage at the connection in the prior art. When constructing the chamfer strip in this application, the direct plug-in method is adopted, which can improve the installation efficiency of the template 20 and avoid the waste problem of the template 20. After the template 20 is inserted into the groove 100, under the restriction of the corner strip body 10, the ends of the two templates 20 can form a certain mutual support, thereby improving the strength of the connection position and reducing the risk of chamfer strip deformation.
