Embodiment 1

[0058] Embodiment one: see figure 1 , figure 2 , Figure 2-1-Figure 2-3 , image 3 , Figure 3-1-Figure 3-3 , Figure 4 , Figure 4-1-Figure 4-3 , Figure 5 , Figure 5-1-Figure 5-3 , a steel dam space truss structure unit body, comprising a space truss structure approximately trapezoidal hexahedron. The front and rear end surfaces of the approximately trapezoidal hexahedron space truss structure are respectively "Tian"-shaped connection structures. figure 1 The middle and front faces are the planes where nodes A, B, C, D, E, F, G, H, and O are located, and the rear faces are A', B', C', D', E', F', G', H', O'; the left, right, upper and lower sides of the frame are "day"-shaped structures, in figure 1 The middle left view is the plane where nodes E, B, F, F', B', E' are located, the right side is the plane where nodes H, D, G, G', D', H' are located, and the upper side is E , A, H, H', A', E' are the planes where the nodes are located, and the lower side is the pla...

Embodiment 2

[0069] Embodiment two: see Figure 6 , the meaning of the numbering and numbering is the same as that of the first embodiment, and the content is basically the same as that of the first embodiment, and the similarities will not be repeated. The difference is that the support plate 11 can also be fixed between the two parallel connecting ears 9 . The supporting plate 11 is vertically fixed with the two connecting ears 9 respectively, and one end of the connecting ear 9 and the supporting plate 11 therebetween is fixed on the side of the connecting rod 8 (vertical column connecting rod) (that is, one end of the connecting ear 9 is connected to the connecting rod). Rod 8 is contacted and fixed, and one end of support plate 11 is contacted or fixed by connecting rod 8), the other end of connecting ear 9 and the support plate 11 therebetween is abutted (or butt fixed) with the end face of horizontal or oblique connecting rod 8, and A connecting piece 10 is fixed on the adjacent sid...

Embodiment 3

[0070] Embodiment 3: the accompanying drawings are not drawn, the meaning is basically the same as that of the embodiment, and the similarities will not be repeated. The difference is: the connecting rods are circular shaped steel connecting rods, and the two ends of the circular connecting rods are used as parallel planes. For example, the two ends of the circular connecting rod are made into a square steel shape.

Abstract

The invention relates to a steel dam space truss structure unit body and an arch-style steel dam. The unit body is a hexahedral space truss structural body with a front end surface and a rear end surface in key pattern structures and other lateral surfaces in a stud link chain structure, connecting rods are respectively arranged between a central node O of the front end surface and other nodes, supporting connecting rods are respectively arranged between four middle nodes A,B,C and D of the front end surface and four vertexes of the rear end surface, and supporting connecting rods are respectively arranged between a central node O' of the rear end surface and the four vertexes of the rear end surface. The steel dam, which is a space truss structure with a curve upstream surface, is formed by combining the space truss structure unit bodies, an eliminator is fixed on the curve upstream surface, the bam bottom of the steel dam is fixed with a reinforced concrete bearing platform, and both sides of the steel dam are respectively fixed with the stepped bearing platform formed by reinforced concrete structures at both banks. The steel dam is kept stable mainly by the counteraction of arc ends at both banks and has strong overload capacity, high degree of safety and engineering investment saving.

Description

1. Technical field: [0001] The invention relates to a dam structure improvement technology for water conservancy and hydropower projects, in particular to a steel dam space truss structure unit body and an arched steel dam. 2. Background technology: [0002] At present, the water retaining structures in water conservancy and hydropower projects mainly include gravity dams, earth-rock dams and arch dams. The water conservancy projects of these three types of dams all have the characteristics of large investment, long construction period, difficult construction and relatively large impact on the environment. For different building types, the following specific analysis of the existing deficiencies. [0003] The working characteristic of the gravity dam is to rely on the anti-sliding force generated by the dam body's own weight to meet the stability requirements of the dam body, and rely on the compressive stress generated by the dam body's own weight to offset the tensile str...
