Description

Assembled self-insulating straw brick

technical field

The utility model relates to an assembled self-insulating light-weight wall suitable for multi- and high-rise concrete structures, steel structures, and bamboo/wood structure buildings.

Background technique

At present, the thermal insulation measures of various building walls in China are mainly to add mineral thermal insulation materials to the external walls, or to use various hollow blocks with built-in inorganic thermal insulation materials. The disadvantages of this thermal insulation measure are: (1) The thickness of the wall is large and the construction technology Complex, difficult to control quality, poor weather resistance; (2) Due to the use of non-insulation material skeleton, there are a large number of thermal bridges in the wall, and the insulation effect is poor; (3) Due to the use of sintering technology or autoclaved technology, the manufacture of such walls The body still consumes a large amount of energy and non-renewable mineral resources, the effect of energy saving and emission reduction is not significant, and the damage to the environment is still great; (4) The wall bricks made of mineral materials are self-heavy, resulting in heavy structures and unfavorable earthquake resistance.

It has been reported that low-density panels made of crop straws are used as wall lining insulation materials, but they cannot be made into brick masonry that meets the wall surface strength, building modulus requirements, and proper geometric configuration. See application reports. Due to the large thickness of the wall, low-density boards were used in the past straw walls. This board has better thermal insulation and sound insulation performance, but its strength is low, which cannot meet the strength requirements of building partition walls, let alone be used as exterior walls; , The wall also needs additional fasteners to be installed, the construction process is complicated, and the quality is difficult to control, so it is difficult to promote.

Contents of the invention

The utility model proposes an assembled self-insulating light wall body. Its purpose is to use crop straw as raw material to produce self-insulating lightweight wall bricks with high surface strength and relatively low internal strength, which can be assembled and installed, to replace traditional mineral wall bricks.

The technical solution of the utility model: it is characterized in that both sides of the low-density inner lining board are high-density outer panels; the upper end of the low-density inner lining board is a tenon; the lower end of the low-density inner lining board is a groove, and the high-density outer panel and The low-density lining boards are staggered to form tenons and grooves.

The utility model has the advantages of adopting a sandwich structure with a tenon and a groove, the wall assembly does not need any additional connectors, the construction is convenient, and the surface strength is high, which can be used as both the interior wall of the building and the exterior wall of the building . The surface strength of this kind of wall can be easily achieved by adjusting the density of the outer panel, and the thermal insulation and sound insulation performance can be adjusted through the thickness of the low-density inner lining board. It is easy to achieve the target thermal insulation, sound insulation and strength indicators. It is an excellent The self-insulating green wall has broad application prospects.

Description of drawings

Accompanying drawing 1 is the structure diagram of assembled self-insulation straw brick.

Accompanying drawing 2 is the side view of Fig. 1.

1 in the figure is a high-density (high-strength) outer panel; 2 is a low-density lining board; 3 is a tenon; 4 is a groove.

Detailed ways

With reference to the accompanying drawings, its structure is that both sides of the low-density lining board 2 are high-density (high-strength) outer panels 1; the upper end of the low-density lining board 2 is a tenon 3;

Straw bricks consist of two high-density (high-strength) straw boards and one low-density (lower strength) straw board to form a sandwich structure, in which the high-density board 1 is located on both sides of the straw bricks to provide higher surface strength for the brick block , the low-density board 2 is located in the middle layer of the brick block, and its main function is heat preservation and sound insulation. High-density (high-strength) outer panels 1 and low-density inner lining panels 2 are staggered to form tenons 3 and grooves 4 to facilitate assembly. The high-density (high-strength) outer panel 1 and the low-density inner liner 2 are integrated by hot pressing.

The thickness of the outer panel 1 is not less than 20mm, length × width = 300mm × 600mm; the thickness of the inner low-density board 2 is divided into 80mm, 160mm, 210mm, length × width = 300mm × 600mm; groove depth or protruding tenon The length is 40mm.

Claims (1)

1. assembling self-heat conserving stalk brick is characterized in that low-density interior lining panel both sides are high density outer panels; The upper end of low-density interior lining panel is a tenon; The lower end of low-density interior lining panel is a groove, and the placement of staggering of high density outer panels and low-density interior lining panel forms tenon and groove.
