Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a spiral-reinforced concrete trough-shaped component. Background Technology

[0002] There are two existing methods for fabricating the side stirrups in ribbed slabs: closed stirrups and open stirrups. Both methods have certain drawbacks. (See also...) Figure 5 The closed stirrup design involves setting closed stirrups 8 at certain intervals inside the side plate. The stirrups have 135° hooks with a hook length of 10d (d is the stirrup diameter). This design requires manual labor for the integrity, fabrication, and binding of the stirrups, resulting in low efficiency, high steel consumption, poor economic performance, and is neither environmentally friendly nor energy-saving. (See also...) Figure 6 The open stirrup design involves setting open stirrups 9 at certain intervals inside the side plate. The stirrups are equipped with 135° hooks with a hook length of 10d (d is the stirrup diameter). This design requires manual completion, fabrication, and binding of the stirrups, resulting in low efficiency and reduced steel consumption compared to the first design. However, the upper end of the stirrups is not closed, leading to poor seismic performance.

[0003] In summary, there is an urgent need for a ribbed beam-slab structure with side plate stirrups that can guarantee seismic performance while reducing material and labor costs to solve the problems existing in the current technology. Utility Model Content

[0004] The purpose of this utility model is to provide a spirally reinforced concrete trough-shaped member to solve the technical problem that the side plate stirrups of the existing ribbed beam plate cannot simultaneously meet the requirements of seismic performance and low cost. The specific technical solution is as follows: This utility model provides a spirally reinforced concrete trough-shaped component, including an integrally formed plate and two side plates. The two side plates are fixed to both sides of the plate along the length direction of the plate. The side plates are provided with spiral stirrups, which are located inside the side plates or located inside the side plates and protrude from the upper surface of the plate. The plate is provided with bottom reinforcing steel bars.

[0005] A further improvement of the spiral-reinforced concrete trough-shaped component of this utility model is that the two ends of the spiral stirrup are bent to form planar stirrups.

[0006] A further improvement of the spiral-reinforced concrete trough-shaped component of this utility model is that the inclined bars of the spiral stirrups are uniformly inclined to form one inclined surface, two inclined surfaces, three inclined surfaces, or four inclined surfaces.

[0007] A further improvement of the spiral-reinforced concrete trough-shaped component of this utility model is that the side plate is provided with bottom beam reinforcement along the length direction, and the bottom beam reinforcement extends out of the side plate.

[0008] A further improvement of the spiral-reinforced concrete trough-shaped component of this utility model is that the bottom reinforcement of the beam is at least two bars, and the at least two bottom reinforcement bars are spaced apart.

[0009] A further improvement of the spiral-reinforced concrete trough-shaped component of this utility model is that the side plate is provided with beam top reinforcement along the length direction, and the beam top reinforcement is fixed to the bottom reinforcement of the plate.

[0010] A further improvement of the spiral-reinforced concrete trough-shaped member of this utility model is that the top reinforcement of the beam is at least two bars, and the at least two top reinforcement bars of the beam are spaced apart.

[0011] The application of the technical solution of this utility model has the following beneficial effects: This utility model relates to a spiral-reinforced concrete trough-shaped component. By using spiral stirrups as the stirrups for the side plates of the concrete trough-shaped component, the spiral stirrups are mass-produced through standardized processing technology. Their continuous spiral structure significantly reduces the number of connection nodes required by traditional stirrups. This processing method not only simplifies the construction process but also effectively reduces material waste and labor intensity, saves stirrup hook length, and reduces material and labor costs. Moreover, the spiral stirrups have good integrity, forming a three-dimensional spatial constraint system. The wrapping effect on the core concrete is better than that of discrete stirrup arrangements, which can more uniformly restrict the lateral deformation of the concrete. The structure of the spiral stirrups exhibits better ductility and damage tolerance under dynamic loads, and the constraint effect on the concrete is more reliable, improving the bearing capacity of the concrete side plates. This solves the technical problem in the prior art that the side plate stirrups of ribbed beams cannot simultaneously meet the requirements of seismic performance and low cost.

[0012] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0015] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] See Figures 1-4 As shown, a spirally reinforced concrete trough-shaped member includes an integrally formed slab 1 and two side plates 2. The two side plates 2 are fixed to both sides of the slab 1 along its length. Each side plate 2 is provided with spiral stirrups 3, which are located inside the side plate 2 or protrude from the upper surface of the slab 1. The slab 1 contains bottom reinforcing bars 7. This trough-shaped member is an integrally cast reinforced concrete structure. The portion of the spiral stirrups 3 protruding from the side beams is cast integrally with the cast-in-place surface layer on the slab 1.

[0017] Preferably, the two ends of the spiral stirrup 3 are bent to form planar stirrups 4. Specifically, the first stirrup at both ends of the side plate 2 is a planar stirrup 4 in the same plane. After the first stirrup is processed, the spiral stirrup 3 begins to be formed until the last stirrup forms a planar stirrup 4 in the same plane.

[0018] Preferred, such as Figure 3 and Figure 4 As shown, the inclined bars of the spiral stirrup 3 are uniformly inclined to form one, two, three, or four inclined surfaces. Specifically, since the cross-section of the side plate 2 is rectangular, the spiral stirrup 3 needs to be bent to adapt to the shape of the side plate 2 when spiraling, thus forming a spiral stirrup 3 with a rectangular cross-section. In this embodiment, each segment of the stirrup can be arbitrarily selected to be inclined, thereby forming one, two, three, or four inclined surfaces.

[0019] Preferred, such as Figure 2 As shown, the side plate 2 is provided with bottom beam reinforcement 5 along its length, which extends out of the side plate 2. There are at least two bottom beam reinforcement 5 bars, spaced apart. The bottom beam reinforcement 5 bars can further fix the spiral stirrups 3 as a whole, improving the integrity of the spiral stirrups 3 and the side plate 2.

[0020] Preferably, the side plate 2 is provided with a top beam reinforcement 6 along its length, which is fixed to the bottom reinforcing steel reinforcement 7. There are at least two top beam reinforcements 6, spaced apart. The top beam reinforcement 6 can further fix the spiral stirrups 3 and the bottom reinforcing steel reinforcement 7 as a whole, improving the integrity of the spiral stirrups 3 and the entire channel-shaped component.

[0021] This utility model relates to a spiral-reinforced concrete trough-shaped component. By using spiral stirrups 3 as stirrups for the side plate 2 of the concrete trough-shaped component, the spiral stirrups 3 are mass-produced through standardized processing technology. Their continuous spiral structure significantly reduces the number of connection nodes required by traditional stirrups. This processing method not only simplifies the construction process but also effectively reduces material waste and labor intensity, saves stirrup hook length, and reduces material and labor costs. Moreover, the spiral stirrups 3 have good integrity and form a three-dimensional spatial constraint system. The wrapping effect on the core concrete is better than that of discrete stirrup arrangement, which can more uniformly restrict the lateral deformation of the concrete. The structure of the spiral stirrups 3 exhibits better ductility and damage tolerance under dynamic loads, and the constraint effect on the concrete is more reliable, improving the bearing capacity of the concrete side plate 2. This solves the technical problem in the prior art that the stirrups of the side plate 2 of the ribbed beam plate cannot simultaneously meet the requirements of seismic performance and low cost.

[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
