Description

Technical Field

[0001] This utility model relates to the field of building structures, and in particular to a lightweight concrete building insulation structure. Background Technology

[0002] Currently, thermal insulation measures for building envelopes are being strengthened, with exterior wall insulation developing the fastest and its insulation effect becoming increasingly better. Insulation boards are mainly used for the walls and roofs of residential, industrial, and public buildings, as well as swimming pools, cold storage facilities, boilers, and some insulation projects with special waterproofing requirements.

[0003] However, existing insulation boards are usually installed separately after the building is completed, which prolongs the construction period. In addition, the installation structure of the insulation boards makes them weak after installation and easy to fall off. Utility Model Content

[0004] To solve the above problems, this utility model provides the following solution:

[0005] A lightweight concrete building insulation structure includes an outer insulation layer, a middle insulation layer, and an inner pressure plate; the middle insulation layer is disposed between the outer insulation layer and the inner pressure plate, and includes horizontal channel steels arranged vertically and horizontally and steel columns disposed between the horizontal channel steels, with the upper and lower ends of the steel columns embedded and fixed in the corresponding horizontal channel steels; insulating concrete is poured inside the middle insulation layer; the outer insulation layer is composed of multiple spliced ​​pieces.

[0006] Furthermore, the outer insulation layer and the inner pressure plate are fixedly connected to the steel column by long bolts and to the building concrete beams and columns by expansion bolts.

[0007] Furthermore, the external insulation layer includes interconnected external insulation panels, and the edges of the external insulation panels are provided with mortise and tenon structures that cooperate with adjacent external insulation panels.

[0008] Furthermore, the steel column is a C-shaped steel column including side walls and front and rear walls. The front and rear walls of the steel column are provided with reserved holes for long bolts to pass through; the side walls of the steel column are provided with concrete overflow outlets.

[0009] Furthermore, the reserved hole is rectangular in shape, and the concrete overflow outlet is an oblong hole.

[0010] Furthermore, the transverse channel steel is fixed to the beams, columns, or ground using bolts.

[0011] Furthermore, the spacing between the steel columns is 600mm.

[0012] Furthermore, the insulating concrete is lightweight concrete with a density of less than 500 kg / m³. 3 .

[0013] Furthermore, there is a gap between the steel column and the outer insulation layer and the inner pressure plate.

[0014] Furthermore, the interval distance is 10-15mm.

[0015] The beneficial effects of this utility model are as follows: the insulation structure is formed by the combination of an outer insulation layer, a middle insulation layer and an inner pressure plate, which has a better insulation effect. The middle insulation layer is composed of steel columns as the framework combined with cast lightweight concrete, which is lighter, stronger and has a better insulation effect. The inner and outer layers are constructed together layer by layer, which simplifies the construction and allows the insulation structure to be constructed simultaneously with the building, eliminating the need to carry out the insulation structure construction after the building is completed, thus saving construction time.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] Example 1: As Figures 1 to 2 As shown,

[0021] A lightweight concrete building insulation structure includes an outer insulation layer 1, a middle insulation layer, and an inner pressure plate 3; the middle insulation layer is disposed between the outer insulation layer 1 and the inner pressure plate 3, and the middle insulation layer includes horizontal channel steels 8 arranged vertically and horizontally and steel columns 9 arranged between the horizontal channel steels 8, with the upper and lower ends of the steel columns 9 embedded and fixed in the corresponding horizontal channel steels 8; insulating concrete 2 is poured inside the middle insulation layer; the outer insulation layer 1 is composed of multiple spliced ​​pieces.

[0022] The external insulation layer 1 and the internal pressure plate 3 are fixedly connected to the steel column 9 by long bolts 7, and fixedly connected to the building concrete beams and columns 4 or the ground 5 by expansion bolts 6. The external insulation layer 1 includes external insulation panels 10 spliced ​​together, and the edges of the external insulation panels 10 are provided with mortise and tenon structures that cooperate with adjacent external insulation panels 10.

[0023] The steel column 9 is a C-shaped steel column including side walls and front and rear walls. The front and rear walls of the steel column 9 are provided with reserved holes 11 for long bolts 7 to pass through. The side walls of the steel column 9 are provided with concrete overflow outlets 12. The reserved holes 11 are rectangular in shape, and the concrete overflow outlets 12 are oblong holes.

[0024] The transverse channel steel 8 is fixed to the beam / column 4 or the ground 5 with bolts. The spacing between the steel columns 9 is 600mm. The thermal insulation concrete 2 is lightweight concrete with a density of less than 500kg / m³. 3 There is a gap between the steel column 9, the outer insulation layer 1, and the inner pressure plate 3. The gap distance is 10-15mm.

[0025] During construction, firstly, horizontal channel steel 8 and steel columns 9 are erected to form a steel frame structure. Then, the external insulation panels 10 are spliced ​​together and fixedly connected to the steel frame structure to form the external insulation layer 1. Next, the internal pressure plate 3 is poured. The internal pressure plate 3 is poured in multiple stages, with each pour reaching a certain height and then allowed to solidify. After the internal pressure plate 3 has solidified, lightweight concrete is poured into the steel frame structure until the lightweight concrete reaches the same height as the internal pressure plate 3, at which point it is stopped and allowed to solidify. After the lightweight concrete at this height has solidified, the pouring of the internal pressure plate 3 and lightweight concrete is repeated. When pouring the lightweight concrete, it is necessary to ensure that the lightweight concrete can overflow from the concrete overflow outlet 12 to the outside of the steel column 9, wrapping the steel column 9 and filling the space between the internal pressure plate 3 and the external insulation layer 1.

[0026] This utility model consists of an outer insulation layer 1, a middle insulation layer, and an inner pressure plate 3 to form an insulation structure, which has a better insulation effect. The middle insulation layer is composed of steel columns 9 as the framework combined with cast lightweight concrete, which is lighter, stronger, and has a better insulation effect. The inner and outer layers are constructed together layer by layer, which is simple to construct and can be completed simultaneously with the building. There is no need to carry out the insulation structure construction after the building is completed, which saves construction time.

[0027] Finally, it should be noted that the above examples are merely specific embodiments of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this utility model should be considered within the protection scope of this utility model.
