Description

Energy-saving and environment-friendly multi-row hole self-insulation fully recycled concrete block

technical field

The utility model belongs to the technical field of building material manufacturing, in particular to an energy-saving and environment-friendly self-insulation fully recycled concrete block with multiple rows of holes.

Background technique

In recent years, with the rapid development of my country's construction industry, the problem of energy consumption has become more and more prominent. With the in-depth implementation of the national energy conservation and emission reduction strategy, the requirements for building energy conservation and emission reduction are getting higher and higher.

Contents of the invention

The purpose of the utility model is to provide an energy-saving and environment-friendly multi-row hole self-insulation fully recycled concrete block, which is not only simple in structure, but also beneficial to building wall insulation and energy saving.

The technical solution of the utility model lies in: an energy-saving and environment-friendly multi-row hole self-insulation fully recycled concrete block, including a rectangular block, and the block is arranged with several rows of rectangular hole grooves at intervals along the width direction, located in a row in the middle The width of the rectangular slots is smaller than the width of the rectangular slots located on both sides, and several rectangular slots are respectively arranged at both ends of the block along the width direction.

Further, the distance between two adjacent rows of rectangular holes is 20 mm, and the distance between two adjacent rectangular holes in the same row is 20 mm.

Further, the length and width of the rectangular hole are 80-100mm×10-15mm, and the length and width of the rectangular notch are 25mm×10mm or 65mm×15mm.

Compared with the prior art, the utility model has the following advantages: the hollow rate of the block is 30.1%, the thermal resistance exceeds 0.77m ² ·K/W, and the compressive strength is not less than 5MPa. Realize waste concrete recycling and tailings resource utilization through multiple channels. Through reasonable mix ratio and block pass design, it can achieve energy saving requirements of more than 50%, and it is energy-saving and environmentally friendly, with low cost, light weight, and easy masonry construction. , the effect is good; the design of the pass pattern of the block extends the heat conduction line of the recycled concrete material, and makes full use of the characteristics of the small thermal conductivity of the air, which is conducive to the improvement of the energy-saving effect of the block; at the same time, the layout of the modified pass pattern can be flexibly adopted according to the energy-saving needs Add 1 to 5 rows of polystyrene board, foam cement, expanded perlite and other materials with low thermal conductivity in the air interlayer, and make the block achieve an energy-saving effect of more than 65% or 80% through composite self-insulation.

detailed description

In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific examples are given together with the accompanying drawings and described in detail as follows, but the present invention is not limited thereto.

Refer to Figure 1

An energy-saving and environment-friendly multi-row hole self-insulation fully recycled concrete block, including a rectangular block formed by die-casting from water, cement, recycled fine aggregate, activated tailings micropowder, fly ash and recycled coarse aggregate 1 , the block is arranged with a, b, c, d, e five rows of rectangular holes 11 at intervals from top to bottom along the width direction, and the length and width of the rectangular holes are 80~100mm×10~15mm; wherein, a The length and width of rows b, d, and e are 100mm×15mm, and the width of row c of rectangular holes in the middle is smaller than the width of the rectangular holes on both sides. The length and width of row c of rectangular holes are 80mm×10mm or 100mm×10mm; the two ends of the block are also provided with three rectangular notches 12 along the width direction, and the length and width of the rectangular notches are 25mm×10mm or 65mm×15mm, so that butt joint between two adjacent blocks. The arrangement of this type of hole can make full use of the characteristics of the small thermal conductivity of the air, and effectively improve the energy-saving effect of the block.

In this embodiment, the distance 13 between two adjacent rows of rectangular holes is 20 mm, and the distance 14 between two adjacent rows of rectangular holes in the same row is 20 mm.

At the same time, rows a, b, d and e on both sides are arranged symmetrically with respect to row c located in the middle, and rows a and e are respectively provided with three rectangular holes.

In this embodiment, the three rectangular slots are respectively aligned with rows b, c, and d of rectangular slots and located at the ends of the block in the width direction. The length and width dimensions of the three rectangular slots are 65mm×15mm, 25mm× 10mm and 65mm×15mm.

The above descriptions are only preferred embodiments of the present utility model, and all equal changes and modifications made according to the patent scope of the present utility model shall fall within the scope of the present utility model.
