Description

Technical Field

[0001] This utility model relates to the field of precast wall technology, and more specifically, to a high-strength precast lightweight concrete wall. Background Technology

[0002] Reinforced concrete slab components, also known as wall panels or wall panels, are prefabricated in prefabrication plants or construction sites for use in building assembly. Constructing prefabricated large-panel buildings using precast concrete wall panels can improve the degree of factory and mechanized construction, reduce on-site wet work, save on-site labor, overcome seasonal influences, and shorten the construction cycle. Traditional precast wall panels are mostly assembled through interlocking structures. For example, patent CN221461587U discloses a high-strength precast concrete wall, including concrete support columns and concrete wall surfaces. The concrete support columns are cuboids with positive and negative shapes at both ends. Channels are provided on two adjacent surfaces of the concrete support columns. The top of the channels is open, and the bottom is a U-shaped base plate. Several protrusions are provided on the concrete support columns. A circular insertion hole is opened at the center of the protrusions. Several splicing grooves are provided at the edges of the protrusions. Several cuboid protrusions are provided on both sides of the concrete wall surface. A cylindrical plug is provided at the lower end of the protrusion. Several splicing joints are provided at the edges of the protrusions.

[0003] The aforementioned device facilitates installation and leaves space for pouring concrete at the connection between the wall and the supporting column, further increasing the bonding strength and rigidity between the wall and the supporting column. However, the wall and the supporting column mainly support the wall through the splice joint, which weakens the connection strength and thus affects the overall strength of the wall. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a high-strength precast concrete lightweight wall. The technical problem to be solved by this utility model is: how to improve the strength of the connection between the wall and the precast column.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength precast concrete lightweight wall, comprising a precast wall body and precast columns, wherein concave fixing grooves are provided on both sides of the precast wall body, and supporting steel bars are provided inside the precast wall body, wherein one end of the supporting steel bars is provided with a first externally exposed connecting steel bar inside the concave fixing groove;

[0006] The outer end face of the precast support column is provided with multiple connecting plates, and the interior of the connecting plates is provided with concave casting grooves. The connecting plates are provided with second externally exposed connecting steel bars inside the concave casting grooves.

[0007] In a preferred embodiment, the inner side of the supporting steel bar is provided with a bent tie bar.

[0008] In a preferred embodiment, both ends of the bent tie are provided with reinforcing bars.

[0009] In a preferred embodiment, the interior of the precast wall body is provided with a lightweight sound insulation layer.

[0010] In a preferred embodiment, the precast support is installed on the outside of the precast wall body.

[0011] In a preferred embodiment, the outer end face of the lightweight sound insulation layer is provided with a concrete outer layer.

[0012] In a preferred embodiment, the thickness of the precast wall body in the top view direction is coplanar with the outer end face of the precast support in the top view direction.

[0013] In a preferred embodiment, the inner end face of the concave fixing groove is in contact with the outer end face of the connecting insert plate;

[0014] In a preferred embodiment, the lightweight sound insulation layer is an autoclaved aerated concrete partition wall panel, which is a porous lightweight concrete made from silica sand, cement, and lime as the main raw materials and cured by high temperature and high pressure steam.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] In practical use, this invention, with the corresponding arrangement of the connecting plate, concave fixing groove, first exposed connecting steel bar, second exposed connecting steel bar, and concave casting groove, requires the connecting plate to be inserted into the concave fixing groove when connecting the precast wall body and the precast support column. This causes the first and second exposed connecting steel bars to be misaligned in the top view. Concrete can then be poured into the concave casting groove, resulting in better strength at the connection between the precast wall body and the precast support column. The poured concrete also stably connects the first and second exposed connecting steel bars together, further increasing the strength at the connection between the precast wall body and the precast support column.
