[0013] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.
[0014] Please refer to Figures 1-3 , wherein, Figure 1 A horizontal direction section view schematic diagram of the fair-faced concrete wall provided by an embodiment of the present application is shown in FIG. 2. Figure 2 A vertical direction section view schematic diagram of the fair-faced concrete wall provided by an embodiment of the present application is shown in FIG. 1. Figure 3 A Figure 2 enlarged schematic diagram of the A part in FIG. 1.
[0015] As Figure 1 shown, the fair-faced concrete wall described in the present embodiment comprises a steel frame and a detachable fair-faced concrete surface layer.
[0016] The steel frame at least comprises a first steel bar 111 and a second steel bar 112 extending along a horizontal direction (D1 direction shown in the figure). One end of the first steel bar 111 is connected with one end of a first beam bracket 191, and the other end of the first beam bracket 191 is arranged in a frame column 181. One end of the second steel bar 112 close to the first beam bracket 191 is bent towards the first steel bar 111, and is not connected with the first beam bracket 191. In other embodiments, the other end of the first beam bracket 191 can also be arranged in a vertical beam. The beam bracket is also known as a corbel, which is a support under the beam in the hybrid structure, and its function is to disperse the force of the beam support to the underlying load-bearing object, so as to avoid too much concentrated force on one side to crush the wall. According to the load direction: if the component is a horizontal load, it may be a cross beam; if it is a vertical load, it may be a vertical beam. Cross beam usually refers to a beam that crosses a room or a building structure, which plays a role in supporting the roof or floor. The main task of the vertical beam is to bear the vertical weight from the upper structure. In multi-storey or high-rise buildings, the vertical beam serves as the main load-bearing component between floors, bearing the weight of the upper floor and various live loads (such as people) on the floor.
[0017] The detachable fair-faced concrete layer is wrapped outside the steel reinforcement frame, the inner side of the fair-faced concrete layer forms a containing space 120 for containing fair-faced concrete, and the fair-faced concrete layer can be detached after construction.
[0018] It should be noted that the first steel reinforcement 111 can be a plurality of steel reinforcements extending in the horizontal direction and arranged in the vertical direction, and the second steel reinforcement 112 can be a plurality of steel reinforcements extending in the horizontal direction and arranged in the vertical direction. In the steel reinforcement frame arranged in the fair-faced concrete layer, the specifications and the number of the steel reinforcements extending in the horizontal direction can be determined according to the required strength of the fair-faced concrete wall.
[0019] Specifically, the first steel reinforcement 111 is connected with the first beam bracket 191 by welding. In other embodiments, the first steel reinforcement 111 can also be connected with the first beam bracket 191 by binding steel reinforcement connection or other connection modes.
[0020] The connection between the fair-faced concrete wall and the main structure (such as columns, beams, etc.) is one of the important nodes in the building structure. In the embodiment, one of the steel reinforcements extending in the horizontal direction in the steel reinforcement frame is normally connected with the beam bracket, and the other steel reinforcement is bent at one end and is not connected with the beam bracket, so that the fair-faced concrete architectural effect of the outer facade can be achieved without affecting the stress performance of the main structure, and sufficient deformation capacity can be provided due to the flexible connection with the main structure. Since one steel reinforcement is not connected with the beam bracket, the corresponding fair-faced concrete wall is a non-load-bearing wall, which is convenient to remove without affecting the stability of the overall building structure. From the perspective of architectural effect, the appearance of the fair-faced concrete wall is achieved without affecting the stress performance of the main structure. The fair-faced concrete architectural effect of the outer facade is ensured, and the crack resistance at the outer facade joint is ensured while the deformation capacity under a large horizontal load is ensured.
[0021] Specifically, the effect of the one end of the steel reinforcement being bent and not connected with the beam bracket mainly reflects in the following aspects: 1. absorbing deformation: due to the thermal expansion and shrinkage of the fair-faced concrete wall, and the deformation of the structure caused by various loads during use, the structure provided in the embodiment can absorb these deformations to prevent cracks caused by deformation differences. 2. relieving stress concentration: at the structure connection, stress concentration often occurs due to changes in geometry and stress state, and the structure provided in the embodiment can disperse and relieve these stress concentrations to reduce the damage to the materials at the connection. 3. facilitating construction and maintenance: the structure provided in the embodiment makes the corresponding fair-faced concrete wall a non-load-bearing wall, which is convenient for installation and adjustment during construction, and inspection and replacement during later maintenance. The fair-faced concrete wall provided in the embodiment can be used as various building structures such as building outer walls, inner walls, partition walls, and balconies.
[0022] like Figures 2-3 As shown, the steel reinforcement frame in this embodiment also includes a third steel bar 113 and a fourth steel bar 114 extending vertically (direction D2 in the diagram). Both ends of the third steel bar 113 are connected to one end of a second beam support 192, and the other end of the second beam support 192 is located within the floor slab 182 and the beam 183. The first end of the fourth steel bar 114 is connected to one end of the second beam support 192, and the second end of the fourth steel bar 114 is bent towards the third steel bar 113 and not connected to the second beam support 192. This embodiment, by further configuring one steel bar extending vertically in the steel reinforcement frame to be normally connected to the beam support, and the other steel bar to be bent at one end and not connected to the beam support, achieves the architectural effect of exposed concrete on the facade without affecting the load-bearing performance of the main structure. Furthermore, the flexible connection with the main structure provides sufficient deformation capacity. Since one steel bar is not connected to the beam support, the corresponding exposed concrete wall is non-load-bearing, making it easy to remove when needed without affecting the overall stability of the building structure.
[0023] It should be noted that the third reinforcing bar 113 can be multiple reinforcing bars extending vertically and arranged horizontally, and the fourth reinforcing bar 114 can be multiple reinforcing bars extending vertically and arranged horizontally. In the reinforcing frame set within the fair-faced concrete surface layer, the specifications and quantity of the vertically extending reinforcing bars can be determined according to the required strength of the fair-faced concrete wall.
[0024] Specifically, in this embodiment, the second end of the fourth reinforcing bar 114 is the end close to the floor slab 182 that serves as the floor, thereby providing sufficient deformation capacity without affecting the load-bearing performance of the main structure.
[0025] Specifically, the third reinforcing bar 113 is welded to the second beam support 192, and the first end of the fourth reinforcing bar 114 is welded to the corresponding second beam support 192. In other embodiments, the third reinforcing bar 113 and the second beam support 192 may also be connected by a method such as binding reinforcing bars; the first end of the fourth reinforcing bar 114 and the corresponding second beam support 192 may also be connected by a method such as binding reinforcing bars.
[0026] like Figures 1-3As shown, the fair-faced concrete surface layer described in this embodiment includes an outer wall formwork 121 and an inner wall formwork 122. The outer wall formwork 121 and the inner wall formwork 122 are arranged in pairs to form a accommodating space 120 for accommodating the fair-faced concrete. The fair-faced concrete surface layer can be removed after construction. Specifically, the main bodies of the outer wall formwork 121 and the inner wall formwork 122 are parallel to each other, have the same structural shape, and are of the same size.
[0027] like Figure 1 As shown, in this embodiment, the first reinforcing bar 111 is located near the outer wall formwork 121, and the second reinforcing bar 112 is located near the inner wall formwork 122. The end of the inner wall formwork 122 near the first beam support 191 is bent towards the outer wall formwork 121. Thus, near the first beam support 191, both the inner wall formwork 122 and the second reinforcing bar 112 have bent portions, and their shapes are compatible.
[0028] like Figures 2-3 As shown, in this embodiment, the third reinforcing bar 113 is located near the outer wall formwork 121, and the fourth reinforcing bar 114 is located near the inner wall formwork 122. The inner wall formwork 122 is bent towards the outer wall formwork 121 at one end near the second beam support 192. Thus, both the inner wall formwork 122 and the fourth reinforcing bar 114 have bent portions near the second beam support 192, and their shapes are compatible.
[0029] In some embodiments, the inner surfaces of the exterior wall formwork 121 and the interior wall formwork 122 that come into contact with the fair-faced concrete are smooth panels to facilitate the containment of the fair-faced concrete and to facilitate the removal of the fair-faced concrete surface layer after construction.
[0030] As can be seen from the above, the fair-faced concrete wall provided in this embodiment, by setting one of the horizontally extending steel bars in the steel frame to be normally connected to the beam support, and the other steel bar having one end bent and not connected to the beam support, can achieve the architectural effect of fair-faced concrete on the facade without affecting the load-bearing performance of the main structure. Furthermore, the flexible connection with the main structure provides sufficient deformation capacity. Further setting one of the vertically extending steel bars in the steel frame to be normally connected to the beam support, and the other steel bar having one end bent and not connected to the beam support, can further provide deformation capacity. Since one steel bar is not connected to the beam support, the corresponding fair-faced concrete wall is a non-load-bearing wall, which can be easily demolished when needed without affecting the overall stability of the building structure. From an architectural perspective, it possesses the appearance of fair-faced concrete without affecting the load-bearing performance of the main structure. While ensuring the architectural effect of fair-faced concrete on the facade, it can resist cracking at the facade joints while ensuring the deformation capacity to withstand large horizontal loads.
