Description

Composite prefabricated wallboard with reinforcing belt

Technical Field

The invention belongs to the field of constructional engineering, and particularly relates to a composite prefabricated wallboard with a reinforcing belt.

Background

The prefabricated building meets the requirements of building industrialization and environmental protection, particularly the industrial policy of green building and building industrialization in China, and the demand for the prefabricated building is more and more large. The prefabricated external wall panel is one of the main contents of prefabricated building, and the existing prefabricated wall panel, especially the external wall panel, is mainly made of reinforced concrete, and the prefabricated reinforced concrete external wall has the defects of great weight, no material saving, no energy saving and high manufacturing cost.

The autoclaved aerated concrete block is a main application material in the existing building wall, has the advantages of light weight, high strength, energy conservation, environmental protection and economy, is generally produced all over the country at present, and has high capacity and easily available materials. The prefabricated building is widely popularized in China, and after factory prefabrication of building walls is advocated, the demand for autoclaved aerated concrete blocks can be greatly reduced, so that the productivity in various regions is wasted.

Patent application No. 201710384465.5 discloses a composite prefabricated wall panel with reinforcing ribs, which is constructed by filling lightweight material between the reinforcing ribs, wherein the reinforcing ribs bear the entire load acting on the wall panel. The light building blocks (including autoclaved aerated concrete blocks) can be used for building the wall body, so that the prefabricated building block wall can meet the requirements of transportation, installation and use, and is a better prefabricated wall body solution. However, the groove (usually through) for arranging the reinforcing rib needs to be reserved on the block wall, the groove is difficult to reserve, continuous operation is difficult, the production efficiency is low, and a heat bridge is easily formed on the wall, so that the energy-saving and heat-preserving effects are not good.

Disclosure of Invention

The invention aims to provide a solution for a composite prefabricated wall panel which is manufactured by building blocks and is provided with a reinforcing belt, aiming at the defects of heavy weight, no material and energy saving, high manufacturing cost, complex manufacturing of the existing prefabricated block wall and low production efficiency of the existing prefabricated wall panel of reinforced concrete.

The invention is realized by the following technical scheme:

researches show that the building blocks and the building block glue joints which generally form the masonry have the capacity of bearing bending moment and shearing force, but the bearing capacity of the parts is lower, generally, the design value of the bending tensile strength of the masonry built by autoclaved aerated concrete and special mortar along the through joints is about 0.06MPa (other building block materials are about 0.05-0.11 MPa). The masonry without any reinforcement has a certain out-of-plane bending bearing capacity, but the span for the exterior wall of the building engineering is limited (usually not more than 2 m).

Meanwhile, like a reinforced concrete member, the flexural bearing capacity of the masonry member can be improved by arranging the reinforcement belt for bearing tensile force on the tension side of the masonry member so as to improve the service span. For example, a reinforced concrete reinforcing belt is arranged on the tension side (concrete is mainly used for improving the bond force of a reinforcing steel bar and improving the adhesive force between the reinforcing belt and a masonry, and other high-efficiency methods are also used for adhering high-strength tension materials such as carbon fibers and glass fibers on the tension surface of the masonry.

Therefore, the reinforcing belts are arranged on the wall of the prefabricated building block at certain intervals, the masonry between the reinforcing belts bears the bending load outside the wall and transmits the bending load to the reinforcing belts, and the reinforcing belts bear the whole load of the wall with larger span, so that the technical scheme is good. The present invention is realized based on this technical principle. The specific technical scheme is as follows:

a composite prefabricated wall panel with reinforcing strips comprises a main wall body of building blocks and a plurality of horizontal or vertical reinforcing strips arranged on the surfaces of two sides of the main wall body or close to the inner surfaces of the two sides, wherein the horizontal reinforcing strips and the vertical reinforcing strips are respectively arranged or simultaneously arranged, and the reinforcing strips do not completely penetrate through the wall thickness direction. The reinforcing belt is used for enhancing the bending bearing capacity of the external wall panel vertical to the surface of the wall body.

The composite prefabricated wall panel with the reinforcing belt comprises a hole or a notch which is arranged on an external wall panel, wherein the hole or the notch is a through hole, the notch is arranged on one side or one corner of the panel, and a door and a window on a building wall body can be installed through the hole or the notch.

The one-step solution of the composite prefabricated wall panel with the reinforcing belts comprises the vertical reinforcing belts arranged on the vertical side edges of the holes or the gaps. The vertical reinforcing belt of the hole is used for enhancing the bearing capacity of the wall body at the hole.

The one-step solution of the composite prefabricated wall panel with the reinforcing belt comprises a hole horizontal reinforcing belt arranged on the horizontal side edge of the hole or the notch. The horizontal reinforcing belt of the hole is used for enhancing the bearing capacity of the wall body at the hole.

As a one-step solution of the composite prefabricated wall panel with the reinforcing belts, the reinforcing belts appear in pairs on the two side surfaces of the wall body, and the reinforcing belts appearing in pairs are connected in a reinforcing mode through tie bars. The lacing wires can be made of steel bars or sheets, the lacing wires can enable the reinforcing belts positioned in the compression area not to be easily unstably stripped, and the shearing bearing capacity outside the plane of the masonry wall can also be improved.

As a one-step solution of the composite prefabricated wall panel with the reinforcing belt, the reinforcing belt is embedded into the surface of the wall body. The cross section of the reinforcing belt is sheet-shaped, rectangular, triangular or any other shape. When the reinforcing belt is embedded into the wall surface, the wall surface can be smooth.

A composite prefabricated wall panel with a reinforcing belt is characterized in that building blocks are autoclaved aerated concrete, sintered bricks, cement bricks, ceramsite concrete and other material building blocks.

The composite prefabricated wall panel with the reinforcing belts is characterized in that the reinforcing belts, the vertical reinforcing belts at the hole openings and the horizontal reinforcing belts at the hole openings are made of reinforced concrete, various fiber cloth, steel plates and section steel.

The horizontal reinforcing belts or the vertical reinforcing belts of the hole are generally arranged on the surfaces of two sides of the wall body, and can also be arranged in the middle of the wall body, or 2 sides or 3 sides wrap the side edges of the hole.

The invention has the beneficial effects that: the invention provides a connection scheme of the prefabricated wall panel which has good sealing and waterproof performance, large bearing capacity, convenient connection, compact structure, economy and beauty for the connection between the existing prefabricated external wall panel, particularly the aerated concrete large panel and the main structure.
