Abstract
The utility model relates to a single-pile elevated bearing-platform tower-crane foundation structure, comprising a reinforced concrete cast-in-place pile, a reinforced concrete stand column, a reinforced concrete bearing platform, a tower-crane foundation section or embedded part. The single-pile elevated bearing-platform tower-crane foundation structure is characterized in that the reinforced concrete cast-in-place pile comprises an overground part and an underground part, the upper end of the reinforced concrete cast-in-place pile is fixedly connected with a reinforcement cage which is the reinforced concrete stand column on the same shaft, the upper end of the reinforced concrete stand column is fixedly connected with a reinforcement cage which is the reinforced concrete bearing platform on the same shaft, and the reinforced concrete bearing platform is internally embedded with the tower-crane foundation section or embedded part fixedly connected with a tower body and is fixedly connected with the tower body into a whole through the tower crane foundation section or embedded part. In the single-pile elevated bearing-platform tower-crane foundation structure provided by the utility model, the design of a single pile and the bearing platform is adopted, so that the construction cost is greatly reduced; due to the design of the bearing platform, the tower crane can be installed before earth excavation is carried out so as not to influence the backfill of earthwork in the range of the tower foundation, and thus, later-stage expense and potential safety hazards are avoided; and the single-pile elevated bearing-platform tower-crane foundation structure has the advantages of small construction plane and simple structure, occupies less field, and is suitable for constructions in narrow fields with different soil properties, and the technology is easy to master and implement.
Description
Technical field
The utility model belongs to the tower crane of constructional engineering machinery equipment, relates in particular to the high-order cushion cap tower crane of a kind of middle-size and small-size single pile structure.
Background technology
Tower crane is the visual plant in building trade lifting machine field, and the vertical transport of all kinds of constructional materialss all is mainly to rely on tower crane to finish.The high-order cushion cap of many steel columns basis that the tower crane form that is adopted in the construction work at present is mainly independent cushion cap basis, rood beam basis, pile cap basis and adopts in recent years.
1. independent cushion cap basis and rood beam basis generally place below the excavation of foundation pit face, the back construction of basic earthwork excavation, its shortcoming is that foundation ditch need be put sloping shoveling, bank protection, daily draining, security protection, secondary backfill soil, its basic cross section is big, earthwork construction is many, working face is big, and natural foundation bearing capacity is had requirement;
2. the pile cap basis is a kind of tower crane form that adopts under natural foundation bearing capacity or the not enough situation of the basic resisting moment of toppling for solving, the general 1-4 root castinplace pile that adopts, cushion cap places on the ground, its shortcoming is that foundation ditch need be put sloping shoveling, bank protection, daily draining, security protection, backfill, earthwork construction is many, working face is big, the cost height;
3. many high-order cushion cap of steel column bases are used for the construction work that tower crane is arranged in deep foundation ditch, passes through basement more, 4 castinplace piles of the general employing of this base form, being the four directions arranges, stake withstands on the hole at the end, monimostyly steel column or steel core concrete column in the stake, it is affixed that capital passes through steel platform or concrete bearing platform and body of the tower.This base form has been save the operation of soil excavation, bank protection, daily draining, security protection, backfill, but cost own is very high.
Though the tower crane form was applicable to the construction work of different characteristics in the past, all exists not to be that operation is exactly the high problem of cost more, and all site condition is had certain requirement.Construction plant, city condition is narrow and small day by day from now on, and each building enterprise of engineering cost efficiency payes attention to all the more, and current tower crane form is difficult to the requirement that condition of compatibility changes.
Summary of the invention
The purpose of this utility model provides the high-order cushion cap tower crane of a kind of single pile structure in order to overcome problem and the shortcoming that above-mentioned prior art exists, and the utility model adopts single pile, cap design of pile to greatly reduce construction costs; Realized that by cap design of pile but tower crane can install, not influence column foot scope earthwork backfill before soil excavation, avoided later stage expense and potential safety hazard; The utility model construction operation face is little, does not account for the place, is applicable to different soil properties, the construction of narrow and small site condition; It is simple in structure, and technology is easy to grasp and implement.
The technical solution of the utility model is:
The high-order cushion cap tower crane of single pile structure, comprise a deposited reinforced concrete pile, reinforced concrete upright column, the steel concrete cushion cap, tower crane joint or embedded part, it is characterized in that: deposited reinforced concrete pile is divided into above and below ground two parts, affixed reinforcing cage is the reinforced concrete upright column of same axle in the deposited reinforced concrete pile upper end, the affixed reinforcing cage in reinforced concrete upright column stake upper end is the steel concrete cushion cap of same axle, and the tower crane joint or the embedded part of pre-buried and body of the tower Joint in the steel concrete cushion cap are by tower crane joint or embedded part and body of the tower is affixed is integral.
With the body of the tower of exposed steel bar cast-in-place concrete pile and reinforced concrete upright column instead of part steel work, like this can the material saving; The steel concrete cushion cap is the connected node of body of the tower and minor diameter reinforced concrete upright column; The diameter of described deposited reinforced concrete pile or reinforced concrete upright column can be less than the body of the tower width.
The utility model adopts single pile, cap design of pile to greatly reduce construction costs; Realized that by cap design of pile tower crane can install, not influence the backfill of the column foot scope earthwork before soil excavation, avoided later maintenance expense and potential safety hazard; The utility model construction operation face is little, does not account for the place, is applicable to different soil properties, the construction of narrow and small site condition; It is simple in structure, and technology is easy to grasp and implement.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
As shown in Figure 1, the utility model comprises a deposited reinforced concrete pile, reinforced concrete upright column 3, steel concrete cushion cap 4, tower crane joint 5, deposited reinforced concrete pile is divided into above and below ground two parts, and under ground portion is 1, overground part is 2,2 affixed reinforcing cages are the reinforced concrete upright column 3 of same axle in the deposited reinforced concrete pile upper end, the affixed reinforcing cage in reinforced concrete upright column post 3 upper ends is the steel concrete cushion cap 4 of same axle, and pre-buried tower crane with body of the tower 6 Joints saves 5 in the steel concrete cushion cap 4, by tower crane joint 5 and body of the tower 6 affixed being integral.
With the body of the tower of exposed steel bar cast-in-place concrete pile and reinforced concrete upright column instead of part steel work, like this can the material saving; The steel concrete cushion cap is the connected node of body of the tower and minor diameter reinforced concrete upright column; The diameter of described deposited reinforced concrete pile or reinforced concrete upright column can be less than the body of the tower width.
The construction sequence of the high-order cushion cap tower crane of single pile of the present utility model structure is as follows:
