Description

Technical Field

[0001] The present invention relates to the technical field of building components, and in particular to an assembled basement prefabricated connection structure. Background Art

[0002] With the continuous development of the construction industry, prefabrication and assembly will become a major trend in the future development of building industrialization due to its advantages such as rapid installation and stable performance.

[0003] Traditional basement beams, slabs, walls and columns are all constructed using cast-in-place methods. This involves a large amount of wet work on site and the use of formwork, especially for floor slabs and basement exterior walls. Each construction sub-project requires a large amount of manpower for on-site operations, resulting in cumbersome construction and frequent cross-operations on site, leading to significant safety hazards and pollution.

[0004] When connecting plates / beams and columns / beams, the joints are generally connected using grouting sleeves. The strength of the joints is relatively weak and mainly relies on the shear resistance of the shear steel bars and concrete at the grouting locations. Summary of the Invention

[0005] The present invention aims to at least partially address one of the technical problems in the related art. To this end, one object of the present invention is to provide a prefabricated connection structure for an assembled basement, where the connection nodes are connected by connecting bent plates and reinforced steel bars, thereby significantly increasing the strength of the connection.

[0006] The technical solutions of the present invention are as follows:

[0007] An assembled basement prefabricated connection structure, comprising:

[0008] If the parts are to be treated, a casting cavity is formed on the end sides that cooperate with each other, and a reinforcement structure is pre-embedded in the casting cavity for cast-in-place reinforcement;

[0009] The reinforcing plate is arranged at the turning point of the casting cavity of the prefabricated part, and is arranged in a V-shape as a whole, with a V-shaped angle α not greater than 90°, and a triangular reinforcement structure is formed on both end sides of the reinforcing plate, and a limiting reinforcing rib that can pass through the triangular reinforcement structure is provided to increase the ability of the reinforcing plate to resist bending.

[0010] Furthermore, the V-shaped angle α is 45°-80°.

[0011] Furthermore, the reinforcing plate includes an abutment plate bent into a V-shaped angle, the end side of the abutment plate is bent to form a bent plate, and a number of connected penetration channels are provided on the bent plate and the abutment plate, and cross-arranged plug-in reinforcement ribs are provided corresponding to the penetration channels to form a triangular stable structure on the end side of the reinforcing plate after penetration.

[0012] Furthermore, the limiting reinforcement ribs on the end side of the reinforcing plate pass through the insertion channel perpendicular to the plug-in reinforcement ribs on the corresponding side, and a reinforcement rib channel is formed at the V-shaped angle end of the reinforcing plate for the limiting reinforcement ribs to pass through.

[0013] Furthermore, the limiting reinforcement rib is arranged in a right-angle shape and passes through the two abutment plates in sequence, and the end side of the limiting reinforcement rib abuts against the surface of the longitudinal rib.

[0014] Furthermore, transverse reinforcement and longitudinal reinforcement are embedded in the end side of the precast top plate, and the transverse reinforcement is arranged to penetrate the casting cavity. Truss reinforcement leaking out of the casting cavity is also embedded in the precast top plate; the casting cavity at the junction of the precast top plate and the precast beam forms the cast-in-place portion of the plate beam.

[0015] Furthermore, the reinforcing plate is arranged at the end side of the prefabricated top plate and inside the turning point of the corresponding casting cavity.

[0016] Furthermore, a cast-in-place section of a beam and column is formed between the precast beam and the precast column for cast-in-place concrete. The reinforcement structure of the precast beam extends into the cast-in-place section of the beam and column. The vertical main reinforcement pre-embedded in the cast-in-place section of the precast column corresponding to the beam and column extends upward into the cast-in-place section of the beam and column. A grouting sleeve is pre-embedded in the bottom of the precast column corresponding to the main reinforcement, which is connected to the plug-in connection reserved in the base plate.

[0017] Furthermore, the longitudinal bars, reinforcing longitudinal bars and reinforcing stirrups embedded in the grooves at the top of the precast beams also extend to the cast-in-place parts of the beams and columns.

[0018] Furthermore, the end side of the prefabricated top plate is erected against the top of the prefabricated wall, and a corresponding cavity is also formed at the top of the prefabricated wall corresponding to the end side of the prefabricated top plate, and together they form the cast-in-place part of the board wall. The prefabricated wall is pre-embedded with reinforcement in the vertical direction extending to the cast-in-place part of the board wall.

[0019] The beneficial effects of the present invention are as follows: by arranging reinforcing plates at the turning points of the casting cavities of prefabricated components, forming triangular reinforcement structures on the end sides of the reinforcing plates, and arranging limiting reinforcing ribs that can pass through the reinforcing plates, the overall bending resistance can be further increased.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.

[0029] Reference Figure 1 and Figure 2 , a prefabricated connection structure of an assembled basement, comprising: a prefabricated top plate 1, a prefabricated beam 2 cast in conjunction with the prefabricated top plate 1, a casting cavity formed on the end side of the prefabricated top plate 1 so that its end side is L-shaped, so as to reserve a cast-in-place area for subsequent construction. Similarly, a casting cavity is reserved on the top of the prefabricated beam 2 for subsequent casting, and a reinforcement structure is pre-embedded in the assembly ends of the prefabricated top plate 1 and the prefabricated beam 2 for cast-in-place reinforcement; a reinforcing plate 3 is prefabricated in the turning point of the prefabricated part corresponding to the casting cavity, and the reinforcing plate 3 is arranged in a V-shape as a whole, and its end sides are basically symmetrically arranged at the turning point of the casting cavity, and its V-shaped angle α is not greater than 90°, preferably 45°-80°, and a triangular reinforcement structure is formed on both end sides of the reinforcing plate 3, and a limiting reinforcing rib 32 that can pass through the triangular reinforcement structure is provided to increase the ability of the reinforcing plate 3 to resist bending.

[0030] like Figure 1, transverse reinforcement 11 and longitudinal reinforcement 12 are pre-embedded on the end side of the precast top plate 1, and the transverse reinforcement 11 is arranged to penetrate toward the casting cavity, and truss reinforcement 13 that partially leaks out of the casting cavity (i.e., the cast-in-place part 14 of the slab beam) is also pre-embedded in the precast top plate 1. The truss reinforcement 13 is arranged against and tied to the longitudinal reinforcement 12, and the leaked truss reinforcement 13 plays a role in strengthening the strength of the cast-in-place part; the casting cavity at the joint of the precast top plate 1 and the precast beam 2 forms the cast-in-place part 14 of the slab beam.

[0031] like Figure 2 and Figure 3 In this example, only the aforementioned reinforcement plate 3 is shown formed in the corresponding casting cavity at the end of the precast top plate 1. The reinforcement plate 3 includes an abutment plate 301 bent into a V-shaped angle. The end of the abutment plate 301 is bent to form a bent plate 302. The bent plate 302 and the abutment plate 301 are respectively provided with a number of interconnected through-channels 303 in the horizontal and vertical directions. Corresponding through-channels 303 are provided with cross-arranged plug-in reinforcement ribs 31 (considering the convenience of pre-embedded reinforcement, a reinforcement is provided against the bent plate 302). After the through-channels 303 are provided, a triangular stable structure is formed at the end of the reinforcement plate 3.

[0032] In this example, the limiting reinforcement rib 32 on the end side of the reinforcing plate 3 passes through the insertion channel 303 at right angles to the plug-in reinforcement rib 31 on the corresponding side, and a reinforcement rib channel 304 is formed at the V-shaped angle end of the reinforcing plate 3 for the insertion of the limiting reinforcement rib 32; considering that the V-shaped angle of the reinforcing plate 3 is an acute angle, the limiting reinforcement rib 32 is set to a right angle shape, passing through the two abutting plates 301 in turn, and the end side of the limiting reinforcement rib 32 abuts against the surface of the longitudinal rib 12. In this example, it abuts against the inner and outer sides of the longitudinal rib 12 respectively to increase the bending resistance and strength of the reinforcing plate 3, thereby increasing the strength of the turning point of the prefabricated part.

[0033] Reference Figure 1 and Figure 4 A beam-column cast-in-place part 25 is formed between the precast beam 2 and the precast column 4 for cast-in-place concrete. The vertical main reinforcement pre-embedded in the precast column 4 corresponding to the beam-column cast-in-place part 25 extends upward into the beam-column cast-in-place part 25. The beam longitudinal reinforcement 21 pre-embedded in the precast beam 2 extends to the beam-column cast-in-place part 25, and beam stirrups 22 are sleeved on the beam longitudinal reinforcement 21 (bundled). The beam stirrups 22 extend to the outside of the precast beam 2, and the beam longitudinal reinforcement 21 is bundled at the top. The beam longitudinal reinforcement 21 at the top also extends into the beam-column cast-in-place part 25, and together form the reinforcement structure of the cast-in-place part of the precast beam 2 and the precast column 4; a grouting sleeve is pre-embedded with the main reinforcement at the bottom of the precast column 4, which is connected to the plug-in connection reserved for the bottom plate (a corresponding grouting gap is reserved at the bottom of the precast part).

[0034] Reference Figure 1 and Figure 5The end side of the prefabricated top plate 1 is erected against the top of the prefabricated wall 5. A corresponding cavity is also formed at the top of the prefabricated wall 5 corresponding to the end side of the prefabricated top plate 1, and together they form a cast-in-place portion 15 of the board wall. The prefabricated wall 5 is pre-embedded with reinforcement extending to the cast-in-place portion 15 of the board wall in the vertical direction, and a water retaining strip is pre-embedded at the top of the prefabricated wall 5.
