Traditional bricks or blocks (including common shale sintered
solid bricks and hollow bricks widely used at present,
solid and hollow bricks of concrete blocks and
cinder bricks, other light aggregate block bricks and strip stone bricks, etc.) and the constructed walls And its construction technology has the following disadvantages: unreasonable structure leads to poor
earthquake resistance and disaster prevention ability, block-by-block workshop construction leads to low work efficiency, difficulty in strict management of construction leads to wall peeling,
water leakage and
water seepage, which is not conducive to line
pipe lines Concealed laying, not conducive to heat insulation and sound insulation of energy-saving buildings, a large number of support tubes need to be used for cast-in-place floor slabs, which wastes cost resources and construction period, and a large number of wall-column-beam building templates are required for cast-in-place walls / columns / beams. Cost resources and construction period, construction and decoration are seriously disconnected, and there is almost no integrated process that integrates decoration links into
building construction. When blocks are used to protect slopes, embankments and walls, they cannot meet the needs of ecological
environmental protection and humanization. Masonry masonry construction The method is single and lacks diversity. For example, when building masonry, it can only be constructed with staggered joints but not through joints, and the single and incomplete technical functions of the blocks lead to a narrow application range, lack of
thermal insulation function, lack of waterproof function, unable to meet ecological requirements, no formwork function or no Substantial formwork effect, too heavy and not light blocks lead to poor safety and low efficiency during construction, high labor intensity and too much reliance on machinery, so it is not applicable in many occasions
[0005] If the traditional
brick wall structure needs to lay wire pipes in the dark, it is necessary to preset grooves on the
brick wall or make additional grooves and dig holes after the masonry is completed, which further reduces the safety of the wall structure and is prone to leakage Water, shelling and foaming, peeling of the surface, and waste of materials and labor; traditional blocks and walls have no additional
insulation layer function, and are not energy-saving buildings. If the wall after masonry needs
thermal insulation and sound insulation, it must Laying the
insulation layer alone on the surface requires secondary construction, which not only wastes resource costs, has a low degree of
standardization, and has many auxiliary processes, but also because the
insulation layer is not integrated with the building wall and has an inherent service life, it needs to be regularly updated and maintained. Directly affect the use cost and life of the building; thirdly, because the insulation layer is attached to the outside of the wall separately, it is also flammable, and the
fire safety is poor
Traditional buildings are seriously out of touch with interior and exterior decoration, and decoration can rarely be integrated into the building in advance, resulting in repeated construction and waste of resources
For example, outdoor wall decoration and indoor wall tiling are all reconstructed after the
civil engineering and wall construction processes are completed. Repeated construction will generate more
construction waste, which is a waste of resource costs and is not conducive to
standardization.
[0006] When traditional blocks are used to build river embankment retaining walls and pit walls, the retaining walls formed are often smooth and tight without gaps. This type of application has the following disadvantages: First, if someone accidentally falls into the water or into the pit, Then it is impossible to rescue yourself and go ashore along the wall, which will easily lead to unnecessary
loss of life; second, the smooth sill also makes the river
bank retaining wall a permanent barren land, without a growth environment for flowers, grasses and
vegetation, and reduces the number of fish, shrimps, crabs, etc. The
habitat and
reproduction of natural ecological organisms is not conducive to the protection of the
ecological environment and ecological cycle; third, due to the traditional masonry model used in construction, there is no internal overall tie structure, which is prone to collapse and landslides, affecting safety and use. The maintenance cost is huge; fourth, the traditional embankment wall is "tightly fitted", so that there is no connection between the surface touching the water and the surface behind the water, so that the natural accumulated water on the
bank, such as rainwater, cannot pass through the wall but can only "go over the wall". It does not meet the ecological requirements. This type of wall has no function of "permeable soil retention". The ideal effect is to make the rainwater and accumulated water on the
bank of the embankment naturally infiltrate into the embankment and the soil will not infiltrate
[0010] For example, CN 1054901C discloses "building blocks, their manufacturing method and building structures using such blocks". Energy-saving and sound-proof walls; there is no
interlocking device on the left and right, and there is no
interlocking assembly connection function for the left and right adjacent blocks. It is inconvenient and quick to align and install during masonry, and the efficiency is not high; the upper convex rib of the block and the corresponding lower concave The mouth is not a continuous whole, and the middle is disconnected, which is not conducive to the overall waterproof and anti-leakage; the shape of the middle hole in the middle of the long side of the block and the shape of the pouring groove around it are strictly corresponding to semicircle and circle with the same
radius. It is not flexible enough to limit the size of the concrete core column. The
radius of the pouring hole is restricted by the thickness of the block, so the cross-sectional area of the pouring hole in the middle cannot be too large, which is not conducive to occasions with more load-bearing and
shear resistance requirements such as higher
layers or the construction of buildings in earthquake zones
[0011] CN 86106157A discloses "fabricated block and construction method using the block". Although the block is provided with a longitudinal through hole, even if it is filled with concrete to form a concrete or
reinforced concrete core column, the The
mortar between adjacent blocks cannot be formed automatically during pouring at the same time, and the
mortar still needs to be bonded between the blocks; the block has no horizontal pouring groove and its device, and cannot form a horizontal concrete core column or a
reinforced concrete core column. The wall cannot be formed into a whole with internal cast-in-place concrete ties; when laying line pipes, they cannot be laid horizontally at will, but can only be laid vertically. When laying horizontally, the line pipes must pass through the beams on the top of the wall. It is convenient for the laying of wires and pipes; the block has no heat insulation and sound insulation device, does not have the function of heat insulation and sound insulation, is not suitable for energy-saving wall construction, and has few functions
[0012] CN 2858834Y discloses a "multipurpose building block". This block has few functions and does not have any
interlocking assembly device and function, so it cannot realize prefabricated masonry. It is inconvenient to quickly align and install during masonry, and the efficiency is not high; Any heat insulation and sound insulation device does not have the function of heat insulation and sound insulation, and is not suitable for energy-saving wall construction and sound insulation wall construction; the length of the block claim is 1200mm, and the height is 300mm. The block is too heavy and has not been realized. The purpose of its light weight is not conducive to manual operations, especially vertical transportation and on-site construction. It relies heavily on
mechanical equipment, and the safety during construction is poor. It is not easy to popularize and promote, and it is not suitable for promotion in the vast rural areas of our country; The middle hole in the middle of the long side of the block and the shape of the pouring groove around it are strictly semicircular and circular with the same
radius. The shape of the hole is not flexible enough. The cross-sectional area should not be too large, which is not conducive to occasions with more load-bearing and shear-resistance requirements, such as buildings with higher storeys or on earthquake zones; Use of column and beam formwork that requires a larger cross-sectional area (such as taller buildings)
[0013] Existing blocks cannot systematically and fundamentally solve the various functional requirements of various building walls
