Embodiment 1

[0058] Example 1: 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 space truss structure unit body of a steel structure dam, comprising a space truss structure body that approximates a trapezoidal hexahedron. The front and rear faces of the approximately trapezoidal hexahedron space truss structure are respectively a "field"-shaped connection structure. figure 1 The middle and front faces are the planes where the nodes of A, B, C, D, E, F, G, H, and O are located, and the back faces are A', B', C', D', E', F', G', H', O'; the left, right, upper and lower sides of the frame are in the shape of "Sun". figure 1 The middle and left view is the plane where each node of E, B, F, F', B', E' is located, the right side is the plane where each node H, D, G, G', D', H' is located, and the upper side is E , A, H, H', A', E' are the planes where each node is located,...

Embodiment 2

[0069] Example 2: see Image 6 , the numbers and the meanings of the numbers are the same as those of the first embodiment, the content is basically the same as that of the first embodiment, and the similarities will not be repeated. The support plates 11 are respectively fixed vertically with the two connecting ears 9, and one end of the connecting ears 9 and the support 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 8). The rod 8 is in contact and fixed, and one end of the support plate 11 is in contact or fixed with the connecting rod 8), the other end of the connecting ear 9 and the supporting plate 11 in between is in contact with the end of the horizontal or oblique connecting rod 8 (or butt-fixed), and A connecting piece 10 is fixed on the adjacent side between the connecting lug 9 and the horizontal or oblique link. When the structure of th...

Embodiment 3

[0070] Embodiment 3: The accompanying drawing is not drawn, the meaning is basically the same as the embodiment, the similarities are not repeated, the difference is: the connecting rods are circular shaped steel connecting rods, and the two ends of the circular connecting rods are parallel planes. For example, the two ends of the circular connecting rod are made into 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 formedby 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...
