Description

Technical Field

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

[0002] When installing existing channel-shaped components, especially when a frame column is placed between two channel-shaped components, the two components need to be spliced ​​together to form a frame beam to meet the load-bearing requirements. There are two existing methods to form this frame beam. One method is to add an additional frame beam between the two channel-shaped components, such as... Figure 7 As shown, this scheme requires the addition of 12 cast-in-place or composite frame beams between the columns, which is complex to construct and costly; Figure 8 As shown, Option 2 replaces the channel-shaped member with side plates on both sides with a channel-shaped member with side beams on both sides. When two adjacent channel-shaped members are spliced, the two side beams on the sides can be spliced ​​to form a frame beam. This option is more expensive and more difficult to construct than using side plates. Furthermore, in existing technologies, the side plates on both sides of the channel-shaped member also use beam reinforcement schemes, such as using open stirrups 13 or closed stirrups 14. Figure 9 and Figure 10 As shown, this not only increases the amount of steel reinforcement used, but also increases the self-weight of the channel-shaped component, making it unsuitable for hoisting.

[0003] In summary, there is an urgent need for a channel-shaped component that can simultaneously offer the advantages of side beams and side plates while requiring less steel reinforcement, in order to solve the problems existing in the current technology. Utility Model Content

The specific technical solution is as follows: This utility model provides a precast concrete trough-shaped component, including the following two structures: the first type includes an integrally formed panel and two side plates; the second type includes two side plates fixed to both sides of the panel along the length direction of the panel; the integrally formed panel, side beam, and side plates, wherein the side beam and the side plates are fixed to both sides of the panel along the length direction of the panel; the side beam is provided with closed stirrups, which protrude from the top of the side beam; the side plates are provided with irregularly shaped stirrups, which protrude from the top of the side plates.

[0005] A further improvement of this utility model of precast concrete trough-shaped component is that the side plate is provided with a bottom reinforcement bar, which is fixed to the lower part of the irregular stirrup.

[0006] A further improvement of this utility model of precast concrete trough-shaped component is that the side beam is provided with bottom reinforcement bars, which are fixed to the lower part of the closed stirrups.

[0007] A further improvement of this utility model of precast concrete trough-shaped component is that the two ends of the bottom reinforcement of the side plate extend out of the side plate, and the two ends of the bottom reinforcement of the beam extend out of the side beam.

[0008] A further improvement of this utility model of precast concrete trough-shaped component is that the side plate is provided with a top reinforcement bar, which is fixed to the upper part of the irregular stirrup.

[0009] A further improvement of this utility model of precast concrete trough-shaped component is that the side plate is provided with a central reinforcement bar, which is fixed to the middle of the irregular stirrup.

[0010] A further improvement of this utility model of precast concrete trough-shaped component is that the panel is provided with a bottom reinforcement bar, which is integrally formed with the irregular stirrup or the irregular stirrup is fixed.

[0011] A further improvement of this utility model of precast concrete trough-shaped component is that the irregular stirrups of the side plate are in the shape of a figure 9 and are integrated with the bottom reinforcement of the panel.

[0012] A further improvement of this utility model of precast concrete trough-shaped component is that the side beam is provided with a beam top reinforcement, which is fixed to the upper part of the closed stirrup.

[0014] A further improvement of this utility model of precast concrete trough-shaped component is that one side of the side beam is inclined or both sides are inclined.

[0015] The application of the technical solution of this utility model has the following beneficial effects: This utility model relates to precast concrete trough-shaped components. Through a structure with a side beam on one side and a side plate on the other, the side beams of two adjacent trough-shaped components can form a frame beam to meet load-bearing requirements. Only the side plate on the other side needs to meet the reinforcement requirements of the side plate, without needing to follow the reinforcement requirements of the side beam.

This utility model simplifies the component reinforcement system, making the steel reinforcement arrangement more consistent with actual stress characteristics; the weight of individual components is reduced, significantly reducing the load on hoisting equipment; on-site, only standardized connection of the side beam nodes is required, improving construction efficiency.

Detailed Implementation

[0019] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] See Figures 1-6 As shown, a precast concrete trough-shaped component includes the following two structures: The first type includes an integrally formed panel 1 and two side plates 3, with the two side plates 3 fixed to both sides of the panel 1 along its length. The second type includes an integrally formed panel 1, a side beam 2, and a side plate 3, with the side beam 2 and the side plate 3 fixed to both sides of the panel 1 along its length. The side beam 2 is provided with a closed stirrup 4 that protrudes from the top of the side beam 2, and the side plate 3 is provided with an irregularly shaped stirrup 5 that protrudes from the top of the side plate 3.

[0021] In this embodiment, the edge beam 2 can be installed on the frame column according to actual needs. The closed stirrup 4 is rectangular, thus adapting to the rectangular edge beam 2 and ensuring the stress requirements of the edge beam 2. This utility model adopts a half-beam and half-slab design, giving full play to the advantages of the edge beam 2 and the side plate 3, which can meet the requirements of the specifications for frame beams, and also has strong construction advantages and project cost advantages. In this utility model, the steel bars in the side plate 3 are bent upward to expose the bottom plate, forming a reinforced concrete composite channel plate with strong shear and tensile reinforcement. Compared with the beam-slab integrated channel member with open stirrups or closed reinforcement, this utility model has the advantages of simple steel plate binding, saving steel consumption, and convenient processing.

[0022] Preferably, the side plate 3 is provided with a bottom reinforcement 6, which is fixed to the lower part of the irregular stirrup 5. There are at least two bottom reinforcement 6. In this embodiment, there are two bottom reinforcement 6, which are respectively fixed at a corner and an end of the bottom bend of the irregular stirrup 5.

[0023] Preferably, the side beam 2 is provided with bottom reinforcing bars 9, which are fixed to the lower part of the closed stirrup 4. There are at least two bottom reinforcing bars 9. In this embodiment, there are two bottom reinforcing bars 9, which are fixed to the two bottom corners of the closed stirrup 4.

[0024] Preferably, the two ends of the bottom reinforcement 6 of the side plate extend out of the side plate 3, and the two ends of the bottom reinforcement 9 of the beam extend out of the side beam 2, thereby facilitating the connection and casting of other nodes of the building structure.

[0025] Preferably, the side plate 3 is provided with a top rib 7, which is fixed to the upper part of the irregular stirrup 5. There are at least two top ribs 7. In this embodiment, there are two top ribs 7, which are respectively fixed at the two lower corners of the top-bent rectangle of the irregular stirrup 5.

[0026] Preferably, the side plate 3 is provided with a central rib 8, which is fixed to the middle of the irregular stirrup 5. There is at least one central rib 8. The central rib 8 can improve the tensile strength at the middle position of the side plate 3.

[0027] Preferred, such as Figure 5 and Figure 6 As shown, the panel 1 is provided with a panel bottom rib 11, which is integrally formed with the irregular stirrup 5 or fixed by the irregular stirrup 5.

[0028] The irregularly shaped stirrup 5 is in the shape of a "9" and is integrated with the bottom reinforcement 11 of the panel. When the bottom reinforcement 11 of the panel and the irregularly shaped stirrup 5 are integrally formed, one end of a steel bar is bent into a "9" shape, while the other end is directly used as the bottom reinforcement 11 of the panel and anchored to the side beam 2 on the other side. Furthermore, when both sides of the panel 1 are side plates 3, both ends of a steel bar can be bent into a "9" shape as the stirrups of the side plates 3 on both sides.

[0029] When the bottom reinforcement 11 of the panel is fixed to the irregular stirrup 5, that is, when the bottom reinforcement 11 of the panel and the irregular stirrup 5 are separately manufactured, a steel bar bent into an unsealed "9" shape and tied to a straight bar is used as the stirrup of the side plate 3. This straight bar directly serves as the bottom reinforcement 11 of the panel. Furthermore, when both sides of the panel 1 are side plates 3, two steel bars with both ends bent into unsealed "9" shapes and tied to a straight bar can be used as the stirrup of the side plate 3. This straight bar directly serves as the bottom reinforcement 11 of the panel.

[0030] Preferably, the side beam 2 is provided with a top beam reinforcement 10, which is fixed to the upper part of the closed stirrup 4. The number of top beam reinforcement 10 is at least two. In this embodiment, there are two top beam reinforcement 10s, which are respectively fixed to the upper part of the closed stirrup 4 and tied to the bottom reinforcement 11 of the anchored panel.

[0031] Preferred, such as Figure 3 and Figure 4 As shown, one side of the side panel 3 is inclined or both sides are inclined, thereby meeting the requirements of irregular building structures.

[0032] Preferably, one side of the side beam 2 is inclined or both sides are inclined, thereby meeting the requirements of irregular building structures.

[0033] This utility model relates to precast concrete trough-shaped components. By using a side beam 2 on one side and a side plate 3 on the other, the side beams 2 of two adjacent trough-shaped components can form a frame beam to meet load-bearing requirements. Only the side plate 3 on the other side needs to meet its reinforcement requirements, without needing to follow the reinforcement requirements of the side beam 2. This saves on steel and concrete usage, simplifies construction, reduces hoisting weight, and solves the technical problems of complex construction and high cost when installing trough-shaped components on frame columns in existing technologies. This utility model simplifies the component reinforcement system, making the steel reinforcement arrangement more consistent with actual load characteristics; the weight of individual components is reduced, significantly reducing the load on hoisting equipment; and only standardized connections of the side beam 2 nodes are required on-site, improving construction efficiency. This utility model effectively overcomes the industry pain points of complex construction procedures and high overall cost in connecting traditional trough-shaped components to frame columns, providing a more economical and efficient solution for prefabricated buildings.

[0034] 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.
