Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a reinforced concrete precast capping beam device. Background Art

[0002] The capping beam is a continuous beam arranged at the top of the retaining structure around the foundation pit. One of its functions is to connect bored cast-in-place piles, rotary bored piles and other pile foundations together to enhance the stability of the retaining structure. Existing capping beams mostly adopt the precast method instead of in-situ casting to improve the construction efficiency.

[0003] The Chinese utility model with the publication number CN214832718U proposes a precast concrete capping beam and a bolt-connected capping beam structure: including a capping beam unit, and a reserved in-situ casting hole is arranged inside the capping beam unit. When the capping beam body is pressed on the pile body, the reserved in-situ casting hole at the capping beam connection and the reserved in-situ casting hole inside the capping beam are above the end face of the pile body, and the pile body and the capping beam can be fixedly connected through the reserved in-situ casting hole at the capping beam connection and the reserved in-situ casting hole inside the capping beam. The capping beams are fixedly connected by inserting screw rods into the reserved small holes between them.

[0004] However, the existing technology still has deficiencies:

[0005] The upper surface of the capping beam body is flat and poured without presetting space for the growth of green plants, which is not conducive to the setting of urban ecological landscapes; at the same time, the capping beam is fixedly installed on the pile body directly through the reserved in-situ casting holes of the capping beam body and the pile body, which is likely to cause instability of the installation structure. Summary of the Utility Model

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a reinforced concrete precast capping beam device, which solves the above problems.

[0007] To achieve the above object, the utility model provides a reinforced concrete precast capping beam device, including a rear plate and a front plate. A connecting plate is fixedly installed between the rear plate and the front plate. The connecting plate includes a middle connecting plate and end connecting plates. The middle connecting plate is fixedly installed in the middle of the rear plate and the front plate. There are a pair of middle connecting plates and end connecting plates. The end connecting plates are symmetrically and fixedly installed at both ends of the rear plate and the front plate. Reserved steel bar holes are arranged on the middle connecting plate and the end connecting plates. A vegetation groove is formed among the rear plate, the front plate and the connecting plate. Installation alignment holes are symmetrically and fixedly installed at the ends of the rear plate and the front plate. Structural steel bars are arranged inside the connecting plate.

[0008] As a further scheme of the utility model: the connecting plate is arranged at the lower ends of the rear plate and the front plate.

[0009] As a further solution of the utility model: embedded steel plates are fixedly arranged at the middle positions of the inner walls of the rear plate and the front plate.

[0010] As a further solution of the utility model: the structural steel bars are inserted through the reserved steel bar holes in the connecting plate for connecting the crown beam body and the pile body at the construction site.

[0011] As a further solution of the utility model: a plurality of groups of drain holes are formed in the rear plate, and the drain holes penetrate through the rear plate and are arranged in the middle of the rear plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. By providing installation alignment holes, when splicing multiple groups of precast crown beams, a steel bar is inserted into the installation alignment holes, and then this steel bar is inserted into the corresponding installation alignment holes, which is convenient for the installation and positioning during the splicing of multiple groups of precast crown beams.

[0014] 2. By providing a vegetation groove and drain holes, and arranging the drain holes on the rear plate and imitating stone decorative patterns on the front plate, it is convenient to plant landscape plants in the vegetation groove; when there is too much water accumulation in the vegetation groove, it can be discharged in time from the drain holes, and at the same time, it does not affect the overall ornamental property of the crown beam.

[0015] 3. By providing reserved steel bar holes on both the middle connecting plate and the end connecting plate, and inserting structural steel bars through the reserved steel bar holes in the connecting plate, the lower part of the structural steel bars is fixedly connected to the structural steel bars of the pile body, and the upper part extends into the lower part of the vegetation groove and lapped with the longitudinal main steel bars of the post-cast strip to form a steel reinforcement cage, and then the steel reinforcement cage is welded to the embedded steel plate to form a stable structural relationship, and finally, concrete is poured to form the post-cast strip, connecting the crown beam body and the lower pile body into a firm whole, which is convenient to fixedly connect the assembled precast crown beam body and the bottom pile body. Compared with directly connecting the pile body through pre-cast holes, the addition of structural steel bars can effectively enhance the tensile and shear bearing capacities between the crown beam and the pile body and improve the stability of the overall structure.

The width of the end connecting plate 10 is half of that of the middle connecting plate 9. When the crown beam bodies are spliced, the end connecting plates 10 at the ends of a pair of crown beam bodies can be spliced and combined to form the middle connecting plate 9. Reserved steel bar holes are provided on both the middle connecting plate 9 and the end connecting plate 10 to facilitate the fixed connection of the assembled prefabricated crown beam body and the bottom pile body. Trapezoidal grooves are opened above both the middle connecting plate 9 and the end connecting plate 10 to facilitate the later casting of concrete; A vegetation groove 12 is formed between the rear plate 1, the front plate 2 and the connecting plate 3. Embedded steel plates 11 are fixedly installed at the middle positions of the inner walls of the rear plate 1 and the front plate 2.
