Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a connecting structure for reinforced concrete precast components. Background Art

[0002] At present, the prestress of the ribbed prestressed reinforced concrete precast component slab band generates an eccentricity on the ribbed prestressed reinforced concrete precast component slab. Under the action of prestress, the precast component slab generates an upward camber, making the bottom of the slab uneven. A large eccentricity results in a large upward camber value; a small eccentricity results in a small upward camber value, and small holes cannot reduce the upward camber value, and it is also inconvenient to pass through steel bars currently.

[0003] The prior art CN1254589C discloses a ribbed prestressed reinforced concrete precast component slab, including a reinforced concrete bottom slab and reinforced concrete longitudinal ribs. Long strip-shaped or long arc-shaped holes are opened on both sides under the longitudinal ribs of the ribbed prestressed reinforced concrete precast component slab. The ratio of the bottom side length L to the hole height H of the long strip-shaped or long arc-shaped holes is L / H≥1.5. Since the eccentricity of the ribbed prestressed reinforced concrete precast component slab is the distance from the prestressed steel bar to the centroid of the cross-section of the precast component slab, the long strip-shaped or long arc-shaped holes separate the bottom slab from the longitudinal ribs at the holes for a long distance, reducing the eccentricity of the precast component slab at the long strip-shaped holes, making the upward camber value of the precast component slab decrease and the bottom of the slab flat, and it is also convenient to pass through steel bars currently.

[0004] However, adopting the above method, during the use process of the precast component, only two plate members can be simply spliced, resulting in insufficient stability of the plate members during use, and thus prone to safety hazards during the use process. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a connecting structure for reinforced concrete precast components, which can strengthen the stability between the plate members during the splicing process of two plate members during the use process of the precast component, and reduce the safety hazards during the use process.

[0006] To achieve the above purpose, the utility model provides a connecting structure for reinforced concrete precast components, including a reinforced concrete bottom slab, reinforced concrete longitudinal ribs and prestressed steel bars. The reinforced concrete longitudinal ribs are fixedly connected to the reinforced concrete bottom slab and are located on one side of the reinforced concrete bottom slab. The prestressed steel bars are fixedly connected to the reinforced concrete bottom slab and are located on one side of the reinforced concrete bottom slab. A splicing device is further included;

[0007] The splicing device includes a plugging rod, a plugging track, a reinforcement component, and a stabilizing component. The plugging rod is fixedly connected to the reinforced concrete floor slab and is located on one side of the reinforced concrete floor slab. The plugging track is fixedly connected to the reinforced concrete floor slab and is detachably connected to the plugging rod. The reinforcement component is arranged on the reinforced concrete floor slab, and the stabilizing component is arranged on the reinforced concrete floor slab.

[0008] Among them, the reinforcement component includes a first threaded groove, a second threaded groove, and a fixing member. The first threaded groove is arranged on the reinforced concrete floor slab; the second threaded groove is arranged on the reinforced concrete floor slab; the fixing member is arranged on the reinforced concrete floor slab.

[0009] Among them, the fixing member includes a reinforcement plate and a locking bolt. The reinforcement plate is detachably connected to the reinforced concrete floor slab; and is located on one side of the reinforcement plate; the locking bolt is threadedly connected to the reinforcement plate and is located on one side of the reinforcement plate.

[0010] Among them, the reinforcement plate has a through groove, and the through groove is adapted to the locking bolt.

[0011] Among them, the stabilizing component includes a positioning track and a positioning bolt. The positioning track is fixedly connected to the plugging rod and is located on one side of the plugging rod; the positioning bolt is threadedly connected to the reinforced concrete floor slab and is threadedly connected to the positioning track.

[0012] A connection structure of a reinforced concrete precast member of the present utility model includes a reinforced concrete floor slab, a reinforced concrete longitudinal rib, a prestressed steel bar, and a splicing device. The splicing device includes a plugging rod, a plugging track, a reinforcement component, and a stabilizing component. During the splicing process of two plate members, the plugging rod on the left side of one of the reinforced concretes is correspondingly inserted into the plugging track on the right side of the other reinforced concrete floor slab, so as to increase the resistance generated between the two reinforced concrete floor slabs. Then, the two reinforced concrete floor slabs are further reinforced by the reinforcement component, so that the stability between the plate members can be enhanced, and the potential safety hazards during use can be reduced.

The utility model provides a connection structure for a reinforced concrete precast component: including a reinforced concrete bottom plate 101, a reinforced concrete longitudinal rib 102, a prestressed steel bar 103 and a splicing device. The splicing device includes a plug rod 104, a plug track 105, a reinforcement component and a stability component. The reinforcement component includes a first thread groove 106, a second thread groove 107 and a fixed component. The fixed component includes a reinforcement plate 108 and a locking bolt 109. The reinforcement plate 108 has a through groove 110. Through the foregoing solution, it is solved that during the use of precast components, only two plate members can be simply spliced, resulting in insufficient stability of the plate members during use, so that potential safety hazards are likely to occur during use. It can be understood that the foregoing solution can be used to enable the precast components to strengthen the stability between the two plate members during the splicing process of the two plate members during use, reduce potential safety hazards during use, and can also be used to greatly improve the stability of the precast components during use and reduce potential safety hazards during use.

[0023] For this specific embodiment, the reinforced concrete longitudinal rib 102 is fixedly connected to the reinforced concrete bottom plate 101 and is located on one side of the reinforced concrete bottom plate 101. The prestressed steel bar 103 is fixedly connected to the reinforced concrete bottom plate 101 and is located on one side of the reinforced concrete bottom plate 101. The reinforced concrete longitudinal rib 102 is welded at the center of the upper surface of the reinforced concrete bottom plate 101.

Long strip-shaped or long arc-shaped holes are opened on both sides below the reinforced concrete longitudinal rib 102. The ratio of the bottom side length L to the hole height H of the long strip-shaped or long arc-shaped hole is L / H≥1.5. The prestressed steel bar 103 is arranged on the front side of the reinforced concrete bottom plate 101. Since the eccentricity of the ribbed prestressed steel bar 103 concrete precast component plate is the distance from the prestressed steel bar 103 to the centroid of the precast component plate cross-section, the long strip-shaped or long arc-shaped hole separates the bottom plate from the longitudinal rib at the hole by a long distance, reducing the eccentricity of the precast component plate at the long strip-shaped hole, reducing the camber value of the precast component plate and making the bottom plate flat, and it is also convenient to thread the steel bars now.

The stability component is arranged at the rear side of the reinforced concrete bottom plate 101. The arrangement of the stability component can strengthen the stability between the two plate members again, thereby reducing potential safety hazards. During the use of the precast component, during the splicing of the two plate members, the insertion rods 104 on the left side of one of the reinforced concretes are correspondingly inserted into the insertion tracks 105 on the right side of the other reinforced concrete bottom plate 101, thereby increasing the resistance generated between the two reinforced concrete bottom plates 101, and then the two reinforced concrete bottom plates 101 are further reinforced through the reinforcement component, so that the stability between the plate members can be strengthened, and the potential safety hazards during use are reduced.
