Description
Technical field
The utility model relates to a kind of building structure, particularly, relates to a kind of load-carrying members and then minimizing reinforcing bar use amount optimized, and impervious function is good simultaneously, is applicable to the Combined reinforced concrete outer wall of basement of one-sided basement and individual layer underground garage.
Background technology
Flourish along with China's construction work industry, the basement structure of underground garage and highrise building is more and more, a large amount of engineering experiences show, the proportion that underground structure part accounts for project total cost is larger, the construction costs that how to reduce underground structure part is very real problem, because underground structure is generally water-tight concrete structure, very strict to the requirement of waterproof, when structure design, to calculate crack width, make it not exceed the scope of regulation and stipulation, to ensure the impervious effect of structure, and structural reinforcement under Crack Control is often very large, very uneconomical, therefore invent a kind of reasonable stress, when effective solution structure is impervious, can effectively reduce the novel structural system of amount of reinforcement, there is very large realistic meaning.
Summary of the invention
The purpose of this utility model is to find a kind of new outer wall of basement Structural Tectonics, to overcome the higher shortcoming of current outer wall of basement structure reinforcing bars content, a kind of reasonable stress is provided, steel content is low, impervious effective Combined reinforced concrete outer wall of basement, existing outer wall of basement structure is single simple reinforced concrete wallboard, body of wall itself is being resisted soil pressure and the water pressure from basement outside, stressed larger, if crack width is controlled in the requirement according to water-tight concrete structure, reinforcing bar content will be very large, the utility model adopts assembled wall structure, the structure that mainly bears soil pressure and water pressure is born by outside retaining wall, and impervious function is mainly born by the outer wall of basement of inner side, outer like this lateral retaining wall is only considered stressed getting final product and need do not controlled according to seepage resistance demand, inner side outer wall of basement significantly reduces because of the pressure bearing, be easy to meet seepage resistance demand, thereby reach the object that reduces structure steel content.
For achieving the above object, the utility model is by the following technical solutions: a kind of Combined reinforced concrete outer wall of basement, comprise steel concrete outer wall of basement 7, it is characterized in that steel concrete outer wall of basement root arranged outside has outside retaining wall 5, the barricade reinforcing bar of described outside retaining wall 5 anchors in the mixed earth of the reinforcing bar basis of steel concrete outer wall of basement 7, between described outside retaining wall 5 and steel concrete outer wall of basement 7, leave space, in described space, be filled with topping I, described steel concrete outer wall of basement 7, outside retaining wall 5, 2 outsides, reinforcing bar mixed earth basis are provided with waterproofing course 8, described waterproofing course 8 arranged outside matcoveredns.
As preferably, the height of described outside retaining wall 5 is 1/4 ~ 1/3 of steel concrete outer wall of basement 7.
As preferably, the cross section of described outside retaining wall 5 is rectangle or trapezoid cross section.
As preferably, described outside retaining wall 5 for the mixed earth retaining wall of reinforcing bar or material be the gravity retaining wall of rubble or plain concrete.
As preferably, the topping I filling in space between described outside retaining wall 5 and steel concrete outer wall of basement 7 is polyphenyl plate 6.
As preferably, the topping of described steel concrete outer wall of basement 7 lateral surfaces is polystyrene board protecting layer 9, and its end face is top board cement mortar protective course 10; The topping of described outside retaining wall 5 lateral surfaces is cement mortar protective course 4; The topping of the mixed earth of described reinforcing bar basis 2 lateral surfaces is brick wall topping 3.
Compared with prior art, this is suitable for the novel following beneficial effect that has: the utility model has been broken through the concept of traditional structure form, change the mode of transfer force of traditional outer wall of basement, creationary impervious structural element is separated with force structure member is suitable, to reach the effect of giving full play to structural element performance, thereby reach the object that reduces structure reinforcing bars consumption.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
A kind of Combined reinforced concrete outer wall of basement of Fig. 1 sectional drawing.
In figure: 1 concrete cushion, 2 reinforced concrete foundations, 3 brick wall toppings, 4 cement mortar protective courses, 5 retaining walls, 6 polyphenyl plate, 7 steel concrete outer wall of basement, 8 waterproofing courses, 9 polystyrene board protecting layer, 10 top board cement mortar protective courses.
Detailed description of the invention
As shown in Figure 1, a kind of Combined reinforced concrete outer wall of basement, comprise steel concrete outer wall of basement 7, it is characterized in that steel concrete outer wall of basement root arranged outside has outside retaining wall 5, the barricade reinforcing bar of described outside retaining wall 5 anchors in the mixed earth of the reinforcing bar basis of steel concrete outer wall of basement 7, between described outside retaining wall 5 and steel concrete outer wall of basement 7, leave space, in described space, be filled with topping I, described steel concrete outer wall of basement 7, outside retaining wall 5, 2 outsides, reinforcing bar mixed earth basis are provided with waterproofing course, described waterproofing course arranged outside matcoveredn, the height of described outside retaining wall 5 is 1/4 ~ 1/3 of steel concrete outer wall of basement 7, the cross section of described outside retaining wall 5 is rectangle or trapezoid cross section, described outside retaining wall 5 for the mixed earth retaining wall of reinforcing bar or material be the gravity retaining wall of rubble or plain concrete, the topping I filling in space between described outside retaining wall 5 and steel concrete outer wall of basement 7 is polyphenyl plate 6, the topping of described steel concrete outer wall of basement 7 lateral surfaces is polystyrene board protecting layer 9, its end face is top board cement mortar protective course 10, the topping of described outside retaining wall 5 lateral surfaces is cement mortar protective course 4, the topping of the mixed earth of described reinforcing bar basis 2 lateral surfaces is brick wall topping 3.
In implementation process, the mixed earth of reinforcing bar basis 2 downsides arrange concrete cushion 1, and the gap length between outside retaining wall 5 and steel concrete outer wall of basement 7 should not be less than 70mm, in space, fill by polyphenyl plate, the retaining wall 5 in outside mainly bears soil pressure and the water pressure of bottom, its height and thickness all should carry out calculative determination according to force request, during internal layer steel concrete outer wall of basement 7 mainly bears, the soil pressure on top and water pressure, cross section and arrangement of reinforcement are by calculative determination, make its crack width meet the requirement of current national codes, to ensure the impervious effect of structure, thickness of section is not less than 250mm, described waterproofing course should wrap at steel concrete outer wall of basement 7, reinforced concrete retaining wall 5, the outside on the mixed earth of reinforcing bar basis 2, become as a whole, to ensure waterproof effect, inner side steel concrete outer wall 7 is impervious structure, constuction joint should be retained in the position that basic end face is not less than 300mm above, constuction joint position should arrange the high steel plate water stopper of 300mm, and outside reinforced concrete retaining wall does not need to consider impervious, and constuction joint can be retained in basic top side location.
