Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and particularly relates to a ribbed sandwich all-lightweight concrete grid board. Background Art

[0002] With the development of modern industrial technology, prefabricated buildings have gradually replaced the ordinary building systems in the prior art due to advantages such as fast construction speed, little restriction by climatic conditions, and labor saving. Generally, the wall panel is a solid concrete slab, which has high production cost, large self-weight, and poor heat preservation effect. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems of large self-weight and poor heat preservation effect of the wall panel in the prior art, and to propose a ribbed sandwich all-lightweight concrete grid board.

[0004] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0005] A ribbed sandwich all-lightweight concrete grid board includes a lower panel, an upper panel, and two lightweight layers located between the lower panel and the upper panel. The lightweight layers include an upper lightweight layer and a lower lightweight layer, which can greatly reduce the self-weight of the bridge board.

[0006] Specifically, the lower lightweight layer includes lower lightweight filling blocks, and the upper lightweight layer includes upper lightweight filling blocks. The upper lightweight filling blocks are located above the lower lightweight filling blocks and are in contact with the lower lightweight filling blocks. The four side surfaces of the upper lightweight filling blocks are provided with protruding contact edges, and the contact edges between the upper lightweight filling blocks are in contact with each other. The lower lightweight filling blocks and the upper lightweight filling blocks are located in a cavity formed by the lower panel, the upper panel, longitudinal rib beams, and transverse rib beams.

[0007] Further, the longitudinal rib beams include lower longitudinal rib beams and upper longitudinal rib beams, and the transverse rib beams include lower transverse rib beams and upper transverse rib beams. The lower longitudinal rib beams and the lower transverse rib beams are located between the contact edges and the lower panel, and the upper longitudinal rib beams and the upper transverse rib beams are located between the upper panel and the contact edges. Columns are provided between the contact edges, and the columns are used to connect the upper and lower rib beams to maintain the integrity of the plate body.

[0008] ] Preferably, wire meshes are respectively arranged inside the lower panel and the upper panel to improve the toughness and support strength of the plate body.

[0009] Preferably, the materials of the lower panel, the upper panel, the longitudinal rib beams, and the transverse rib beams are lightweight aggregate structural concrete with a bulk density less than 1200 kg / m³, a thermal conductivity less than 0.5 W / (m•k), and a strength greater than 10 Mpa. It is lightweight, and at the same time reduces the thermal bridge effect at the edges and cross-columns of the plate body, improving the heat preservation effect of the plate body.

[0010] Preferably, the lower lightweight filling block and the upper lightweight filling block are made of lightweight materials with a thermal conductivity less than 0.05 W / (m•k) and a bulk density less than 50 kg / m³. They are lightweight and have a heat preservation effect, such as polystyrene foam boards. The cooperation of the two lightweight filling blocks can greatly improve the heat preservation performance of the plate body, and the contact edge of the upper lightweight filling block is used to improve the heat preservation performance at the longitudinal rib beams and transverse rib beams.

[0011] The present invention also provides a manufacturing method of the above-mentioned ribbed sandwich all-lightweight concrete grid plate, which includes the following steps:

[0012] Step S1: Lay a lower panel containing a steel wire mesh in the mold;

[0013] Step S2: Lay the lower lightweight filling block on the lower panel;

[0014] Step S3: Pour lower longitudinal rib beams and lower transverse rib beams between the lower lightweight filling blocks;

[0015] Step S4: Lay the upper lightweight filling block above the lower lightweight filling block;

[0016] Step S5: Pour columns, upper longitudinal rib beams and upper transverse rib beams between the upper lightweight filling blocks. The columns are located between the contact edges, and the upper longitudinal rib beams and upper transverse rib beams are located in the upper space of the contact edges between the upper lightweight filling blocks;

[0017] Step S6: Lay an upper panel containing a steel wire mesh above the upper lightweight layer.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. Two lightweight layers are arranged inside the ribbed sandwich all-lightweight concrete grid plate, and the lightweight filling blocks inside the lightweight layers are all foam boards, which can greatly reduce the self-weight of the plate body. The contact edge of the upper lightweight filling block can improve the heat preservation performance at the longitudinal rib beams and transverse rib beams, and enhance the heat preservation effect of the plate body;

[0020] 2. Steel wire meshes are arranged inside the lower panel and the upper panel of the ribbed sandwich all-lightweight concrete grid plate. The lower panel, the upper panel, the longitudinal rib beams, the transverse rib beams and the columns adopt lightweight aggregate structural concrete. The lightweight filling blocks are lightweight and have a heat preservation effect. Therefore, the plate body has a light self-weight, good heat preservation performance and high structural strength.
