Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of thermal insulation composite wallboard, especially relates to a double-wall sandwich thermal insulation board and forming system thereof. BACKGROUND

[0002] Sandwich thermal insulation board (referred to as "sandwich thermal insulation board") refers to the composite board formed by sandwiching thermal insulation material between two layers of concrete wallboard, which is generally widely used in external walls. It can enhance the thermal insulation and energy saving performance of external walls, reduce the fire hazard of external walls, prolong the service life of wallboard and reduce the maintenance cost of external walls.

[0003] However, the existing sandwich thermal insulation board has some drawbacks during installation and construction, such as: in JGJ-T269-2012 "Application Technical Specification for Light Steel Wire Mesh Polyphenyl Board Concrete Components", the thermal insulation board (polyphenyl board) is fixed on both sides of the steel wire mesh by inclined insertion of the wire, and workers need to perform insertion work on both sides during construction, resulting in waste of labor cost; in Chinese patent CN118881061A lightweight composite wall and its installation method, a scheme is recorded for positioning the lightweight wallboard sandwich by using Z-shaped vertical keel, which forms a reversible folded edge buckle on both side flanges of the Z-shaped steel, and the lightweight wallboard is clamped and fixed by turning the folded edge buckle to match the opposite flanges. Although it improves the structural stability and convenience, the installation of the structural net still needs to be fixed by wire tying or fixed by shooting nails and other anchoring devices, and the two concrete structure layers do not form a synergistic effect with the keel, but only act as separate single wall on both sides.

[0004] Therefore, how to provide a sandwich thermal insulation board with better structural strength and easier installation and forming is a problem to be solved by the utility model.

[0005] It should be noted that the information disclosed in the background section of the utility model is only intended to deepen the understanding of the general background of the utility model, and should not be considered as recognition or any form of implication that the information constitutes prior art known to those skilled in the art.

The light steel joist is punched to form the through hole 10 at the position facing the heat insulation board 2, and the punched area is bent to form the positioning member 11. In the factory, the light steel joist is pressed to form a three-edge groove by equipment, and the bottom is kept closed. When the heat insulation board 2 is installed, the pressed area is bent outward to form the positioning member 11, and the bent pressed area forms the through hole 10. Specifically, the multiple positioning members 11 on the light steel joist are arranged at intervals in the height direction, and the multiple positioning members 11 are sequentially bent to form the positioning members 11 on the two sides, so as to clamp the heat insulation boards 2 on the two sides of each light steel joist.

[0052] The through hole 10 and the positioning member 11 can be formed by stamping the structure of the support keel 1 itself, which is simple and convenient.

[0053] Embodiment 2:

[0054] Please refer to FIG Figure 7 , Figure 8 , and in combination Figures 1-6 , the embodiment provides a double-wall sandwich panel forming system, which comprises a double-wall sandwich panel and a coating device 5; the concrete cover layer 4 is formed by the coating device 5, and the coating device 5 comprises a push rod 51, a spraying pipe 52 and a troweling plate 53; the push rod 51 is supported on the troweling plate 53; the troweling plate 53 comprises a troweling plate body 531 and a slurry collecting plate body 532; the spraying pipe 52 is arranged on the slurry collecting plate body 532; the spraying pipe 52 sprays slurry in the slurry collecting space between the slurry collecting plate body 532 and the insulation panel 2 and is troweled by the troweling plate body 531, so as to form a coating area of the concrete cover layer 4.

[0055] The troweling plate body 531 and the slurry collecting plate body 532 in the troweling plate 53 are integrally formed, and form a general inclined angle; the embodiment does not particularly limit the angle, and aims to form a certain angle for receiving slurry. The spraying pipe 52 can be one or more, and is preferably multiple; the multiple spraying pipes 52 are uniformly arranged along the slurry collecting plate body 532.

[0056] The troweling plate 53 is troweled by manually holding the push rod 51. In order to adapt to different angle changes during troweling, a plurality of supporting legs 54 are arranged on the push rod 51, part of the supporting legs 54 are hinged to the troweling plate body 531, and part of the supporting legs 54 are supported on the slurry collecting plate body 532 by elastic members. Specifically, the supporting leg 54 is connected to the troweling plate body 531 by a hinge or a universal shaft. The elastic member is preferably a spring 541, which is connected between the slurry collecting plate body 532 and the supporting leg 54, so as to adapt to different angle changes in the troweling process from bottom to top.

[0057] In order to better spray coating, the embodiment is optimized to design the area between two adjacent support keels 1 as a coating area. Correspondingly, the width of the troweling plate body 531 and the mortar collecting plate body 532 is not less than the interval of the two adjacent support keels 1, so that the side mold effect formed by the two adjacent support keels 1 can be troweled once, and the mortar leakage is reduced.

[0058] The beneficial effects of the embodiment are as follows:

[0059] The double-wall sandwich heat insulation board is sprayed and troweled by the coating device 5, and compared with the traditional multi-layer troweling, the mortar is sprayed by the mortar spraying pipe 52 in the mortar collecting space between the mortar collecting plate body 532 and the heat insulation board 2 and is troweled by the troweling plate body 531, so that a coating area of the concrete covering layer 4 is formed, and then the whole concrete covering layer 4 is formed by repeating the operation, and the troweling efficiency is greatly improved.

[0060] The width of the troweling plate body 531 and the mortar collecting plate body 532 is set to be not less than the interval of the two adjacent support keels 1, so that the two support keels 1 become troweling side molds, and the heat insulation board 2 and the troweling plate body 531 are troweled once to be formed.

[0061] The traditional mortar spraying can only spray a half centimeter thick each time, and needs to be sprayed and formed in sequence; the traditional hand troweling is not easy to compact, and the labor cost is high. The present application can improve the troweling efficiency, compact the mortar with the troweling plate body 531, and improve the mortar strength.

[0062] Further, the above embodiment of the present application is described in detail in combination with the drawings, and those skilled in the art can make various changes to the present application according to the above description.
