Detailed Description
The utility model is further described below with reference to the accompanying drawings and examples:
The embodiment is shown in combination with fig. 1, and the combined foundation comprises a rubble retaining wall 6 and a light enclosing wall, wherein the light enclosing wall comprises a metal upright post 2 and a metal column foot plate 3, the plane size of the metal column foot plate 3 is not less than 200mmx200mm, the thickness of the metal column foot plate 3 is not less than 5mm, and the metal column foot plate 3 and the metal upright post 2 are welded together;
The rubble retaining wall 6 is reserved with a plurality of foundation grooves 5 with rough inner surfaces, corresponding metal upright posts 2 and corresponding metal foot plates 3 extend into the corresponding foundation grooves 5, plain concrete with concrete strength of C20 is poured into the foundation grooves 5, plain concrete foundations 1 with the same plane size and depth as those of the foundation pit are formed after the plain concrete is air-dried, and the distance between every two adjacent plain concrete foundations 1 is not more than 3m;
The root position of the metal upright post 2 extending out of the plain concrete foundation 1 is poured with a concrete protection layer 4.
Further, the plain concrete foundation 1 has a plane size of 300mmx400mm, and the plain concrete foundation 1 has a depth of 500mm.
Further, the side length of the plain concrete foundation 1 is not less than h+2c, h is the plane dimension value of the metal skirting board 3, and c is the thickness of the concrete protection layer 4 on the side surface of the metal skirting board 3.
Further, the length of the metal upright post 2 extending into the foundation is not smaller than 300mm or a larger value of 2hc, and hc is the long side dimension of the metal upright post 2.
Further, the root of the metal upright post 2 is provided with the concrete protection layer 4 with the thickness of 50mm and the height of 150 mm.
The utility model can omit the steel bar and has small concrete consumption. The traditional foundation method adopts a foot placing mode, the vertical load and the overturning bending moment of the enclosing wall are met by increasing the plane size of the reinforced concrete belt (or pier) foundation, the consumption of the reinforced concrete and the concrete is large, and the cost is high. The foundation is plain concrete, the bottom and the side wall of the foundation are in direct contact with the rubble, the surface of the reserved foundation groove 5 of the rubble retaining wall is rough, the concrete is bonded with the rubble of the retaining wall and is meshed with the rough surface, and the foundation is good in integrity and beneficial to cooperative stress. The smaller base size provides higher bearing capacity. According to the utility model, the plain concrete foundation 1 is prismatic, the minimum width of the plain concrete foundation 1 can be 500mm or a larger value of the width +2c of the column foot steel plate, and c is the thickness of the protective layer at the end part of the metal column foot plate 3.
The utility model can cancel the template or the brick moulding bed. In the conventional practice, in order to ensure that concrete is poured according to the design size and shape, templates or brick moulding bed are required to be arranged on the periphery of a foundation. The reserved foundation groove 5 of the rubble retaining wall has the same size as the foundation, and no template or brick bed-jig is required to be additionally arranged.
The utility model has better concrete curing effect, high early strength, less cracks and good durability. The periphery of the foundation concrete is surrounded by the grouted rubble, the periphery of the grouted rubble is airtight, the concrete has good heat preservation and moisture preservation functions, the early strength of the concrete is facilitated to be promoted, and shrinkage cracks caused by water loss of the concrete are prevented.
The upper metal upright post 2 is well connected with the plain concrete foundation 1, the force transmission is more direct, in the conventional method, the upper metal upright post 2 is connected with the foundation through the embedded steel plate and the embedded bolt, and the upper load is transmitted to the concrete foundation through the bolt and the steel plate by the metal upright post 2. The connecting steel plate and the bolts need to be additionally paved with a concrete protection layer 4 at the upper part, the risks of falling, rust and loosening exist in the later use process, the durability is poor, and meanwhile, the positioning accuracy of the embedded part in the traditional method has great influence on the positioning of the whole enclosing wall. According to the utility model, the base of the metal upright post 2 is directly embedded into the foundation, and the positioning of the metal upright post 2 is completed. The metal upright post 2, the foundation and the retaining wall form a whole, the upper load can be directly conducted to the foundation, and the force transfer is more direct and effective.
In the traditional method, under horizontal load, eccentric bending moment appears on the substrate, and the overall stability of the enclosing wall is ensured by enlarging the size of the foundation foot-placing. In the utility model, the light metal upright post 2 is integrated with the rubble retaining wall through the foundation concrete, so that the anti-overturning capability is strong. Therefore, the requirement can be met without increasing the basic size, and the stress form is obviously better than that of the traditional method.
