Description

Sandwich insulation external wall panel

technical field

The utility model relates to the field of construction engineering, in particular to a sandwich heat-insulating and externally hung wallboard.

Background technique

The country vigorously promotes building energy-saving technology and building industrialization. As a sandwich insulation external wall panel with dual functions of building energy saving and assembly modularization, it is more in line with national policies and industrial structure adjustments than ordinary external walls. At present, due to the comprehensive consideration of structure and thermal performance, the structure of sandwich insulation and external wall panels is roughly as follows: the inner and outer sides are reinforced concrete thin slabs, and the middle is a sandwich insulation layer, in order to strengthen their joint effect. Integrity, in terms of structure, independent connectors or full-length steel trusses should be set to strengthen the joint effect. Its structure is shown in Figure 1.

However, in practical applications, there are the following problems in this structural form and construction connection form:

1) Use independent connectors or full-length steel trusses to strengthen the connection and integrity between the inner and outer blades, which will inevitably be interspersed and fixed in the insulation layer material, which will damage the sealing of the insulation layer and affect the insulation performance;

2) Due to the thinner inner and outer slabs, pre-embedded hoisting and supporting connectors are required at the hoisting and temporary support points of the second slab. There must be sufficient bonding and fixing requirements between the connectors and the concrete, but the concrete is bound to fail in the thickness direction of the thin slab. To meet this requirement, it is necessary to increase the range of concrete entities in the area of the lifting point or supporting point. Generally, a structure in which the inner and outer blades are connected into a partial whole will be formed, which will connect the cold and hot bridge channels of the concrete and affect the thermal insulation performance.

3) The installation of connectors or steel bar trusses and the installation of insulation materials are not only intertwined, but also can only be done manually, with low labor efficiency and complicated construction. Quality is also difficult to guarantee.

Utility model content

The technical problem to be solved by the utility model is to provide a sandwich thermal insulation external wall panel, which does not require independent connectors or steel trusses and can make the first blade, the second blade and the insulation layer The three are connected stably and have good thermal insulation properties.

The technical solution of the utility model is to provide a sandwich insulation wallboard with the following structure, including a first leaf plate, a second leaf plate and an insulating layer arranged between the first leaf plate and the second leaf plate , the side of the first leaf plate and the second leaf plate close to the thermal insulation layer and the thermal insulation layer are respectively provided with convex ribs and grooves matched with the convex ribs.

Preferably, the ribs include a first rib arranged on the first leaf plate and a second rib arranged on the second leaf plate, and the two sides of the thermal insulation layer are provided with the first rib and the second rib. A matching groove for the second rib.

Preferably, it also includes a hole passing through the first leaf plate, the second leaf plate and the insulation layer, and the side wall of the hole is provided with an inner support layer.

Preferably, the thermal insulation layer is spliced by several thermal insulation strips, and the groove is composed of side walls of several thermal insulation strips.

Preferably, the first protruding ribs and the second protruding ribs are evenly spaced on the side walls of the first vane and the second vane, respectively.

Preferably, the projected position of the first convex rib on the second leaf plate and the position of the second convex rib are alternately distributed.

Preferably, the first protruding rib and the second protruding rib are respectively provided with fixing pieces passing through the first leaf plate and the second leaf plate.

After adopting the above structure, compared with the prior art, the sandwich insulation wallboard of the present utility model has the following advantages: There are several convex ribs, which not only do not destroy the structural strength of the original first blade and the second blade, but also strengthen the structural strength of the first blade and the second blade, because the convex rib increases the strength of the first blade and the second blade The thickness of the local area of the second blade provides a sufficient fixing area for the subsequent setting of pre-embedded hanging parts, hoisting of the entire external wall panel and bonding and anchoring with concrete, reducing the need for fixing the first blade, the second blade and the insulation layer The independent connectors not only save materials but also simplify the construction process and increase work efficiency. Since there are no independent connectors passing through the insulation layer, it not only avoids the phenomenon of cold and heat bridges but also ensures the integrity and sealing of the insulation layer. That is, the thermal insulation performance is guaranteed.
