The invention supplies a environment protection energy saving heat preservation exterior wall coating material that contains polyvinyl alcohol 5-10%, acryloid cement 20-40%, cellulose liquor 10-20%, wollastonite in powder 10-30%, see-bubble powder 2-5%, asbestos fiber 1-4%, expanded perlite 5-12%, and water 10-30%. The raw material taking fully mixing to form thick slurry, it could be coated onto the wall. The invention has strong adhesion, high alkali resistance and high water resistance.

The invention relates to the technical field of building, in particular to a safe supporting structure for foundation pit supporting in civil engineering. Aiming at the defects of simple supporting structures, unstable supporting strength and incapability of draining underground water existing in the prior art, the invention proposes the following scheme: the safe supporting structure comprises supporting plates and a supporting foundation, wherein the supporting plates vertically cling to the sidewall of a foundation pit, two fixed rings are welded on each of the upper edge and the lower edgeof one side, far from the sidewall of the foundation pit, of each supporting plate, the two fixed rings on each of the upper edge and the lower edge are on a straight line, and are symmetrically arranged, two first mounting recesses are reserved under the two fixed rings of the upper edge of each supporting plate, and two second mounting recesses are reserved in each supporting plate under the corresponding two first mounting recesses. According to the safe supporting structure, the supporting effect of the supporting plates on the foundation pit is enhanced, consequently, the shape of the foundation pit is kept undeformed, foundation pit collapse is prevented, and the foundation pit is more stable; the underground water in the sidewall of the foundation pit can be drained out via drainage slots, and ultimately flows into an urban sewer via a drainage channel, and thereby convenience is provided for subsequent construction.

The invention relates to a concentric oval hole forming method of a multilayer overlapping different-curvature circular arc web plate. The method is characterized in that through lofting, the oval center point and the outline of a steel plate neutral layer are determined through mapping software; the oval center point and the outline after the mapping are converted to an outer skin of the steel plate, and patterns are artificially drawn; through programming software, a numerical control cutter is used for cutting; the goal of forming four-row nine-line gradually varied crossing angle concentric circle oval holes in the eight-layer different-curvature overlapping circular arc web plate can be achieved. Compared with the prior art, the concentric oval hole forming method has the beneficial effects that the hole forming positioning accuracy can be ensured; the appearance outline is accurate; the concentric degree of the multilayer hole is high; common production equipment is used; the production cost is reduced; the production resources are saved; the work efficiency is high, and is 5 to 7 times of that of the precise machining equipment; the operation is simple; convenience is realized; the implementation is easy; the requirements on environment are low. The direct precise positioning can be directly realized on the steel plate; the later-stage construction is convenient.

The invention relates to a vertical shaft cylinder structure for a stereo garage. The vertical shaft cylinder structure comprises a cylinder, 12 piles and more than one layer of support floor slab, wherein the cylinder is cast by concrete; the piles are evenly distributed on the cylinder wall of the cylinder; the support floor slab is vertically distributed along the axial direction of the cylinder; the inner cylinder wall of the cylinder is formed by 12 arch walls; a cylinder expansion part is formed at the connected part of two adjacent arch walls; the 12 piles are coated with the 12 cylinder expansion parts respectively; the support floor slab and the cylinder wall of the cylinder are integrally molded; and the support floor slab is in an annular form as a whole. The inner wall of the cylinder is arranged into an arch form, so that effective wrapping on the piles is ensured; meanwhile, the wall thickness at the top point of each arch wall is reduced; the used materials are reduced; the structure of each arch wall is relatively stable; the vertical shaft cylinder structure has relatively good bearing capacity on pressure and shearing force transmitted by earthwork at the outer side. The support floor slab is brought out when the cylinder is cast; construction of a late parking floor slab is greatly facilitated; and meanwhile, the vertical shaft cylinder structure is relative stable as a support base of the parking floor slab.
