Abstract
The utility model discloses a support platform which comprises a supporting structure and used for supporting a fixed type tower crane. The support platform is characterized in that the supporting structure is formed in a way that four section steel columns are buried in the ground; the support platform is a steel platform; the top parts of the section steel columns are fixedly connected with the steel platform; at least one horizontal reinforcement steel beam is arranged between each two adjacent section steel columns. The support platform has the advantages that during the construction process, the bottoms of the section steel columns are inserted into ground and fixed, and the top parts of the section steel columns are fixedly connected with the steel platform, the base structure of the fixed type tower crane can be obtained, so that the construction process is simple, and the construction efficiency is effectively improved with low cost. Moreover, the section steel columns are removed and transported outside in a mechanical way, so that the dismounting process is very convenient and environment-friendly; and the dismounted device can be recyclable and used again, so that the resource is greatly saved.
Description
Technical field
The utility model relates to the foundation structure in a kind of building, especially a kind of foundation structure of fixed base tower crane.
Background technology
Crane is on-the-spot main lifting, plane haulage device of construction work, especially fixed base tower crane, it is little that its foundation structure takies construction plant, flexible arrangement, easy for installation, and tower body can without depending on, other supporters are independent carry out work at certain altitude, tower body adheres to the advantages such as scaffolding height is large after building, so application is quite extensive.
The general pile foundation structure that adopts in fixed base tower crane basis, need to be arranged in the building basement foundation ditch or outside foundation ditch according to construction.
In the time of in fixed base tower crane is arranged in basement foundation ditch, the general concrete drilling bored concrete pile that adopts is as foundation pile, structure commonly used is: the concrete drilling bored concrete pile top is equal with the bottom of basement bottom board, at the bottom of concrete bearing platform a little more than the basement roof face, the foundation bolt of crane derrick tower body is embedded on concrete bearing platform in advance, between the stake top of concrete bearing platform and concrete drilling bored concrete pile, by steel pile, be connected, the upper end of steel pile is stretched in concrete bearing platform, and lower end is inserted in concrete drilling bored concrete pile and carried out anchoring; Concrete bearing platform reaches after design strength the tower body of erection crane again; With the process of excavation of foundation pit, the steel support structure of vertical and horizontal direction is set to strengthen the integral rigidity of steel pile between steel pile.
In the time of outside fixed base tower crane is arranged in basement foundation ditch, general preformed pile or the cast-in-place concrete pile of adopting done basis, structure commonly used is: at the bottom of the stake top embeds concrete bearing platform, the absolute altitude of concrete bearing platform end face is suitable with natural ground, the foundation bolt of crane derrick tower body is embedded on concrete bearing platform in advance, and concrete bearing platform reaches after design strength the tower body of erection crane again.
Mainly there is following shortcoming in fixed base tower crane pile foundation structure practices well:
1, need construction and installation concrete drilling bored concrete pile or preformed pile, also need to carry out the structure such as concreting cushion cap and the step such as steel pile, working procedure more complicated are installed in concrete drilling bored concrete pile;
2, need to consume the resources such as a large amount of steel, concrete, engineering cost has high input, and the construction period is long;
3, the foundation structure of such fixed base tower crane is Bullet structure, once engineering finishes this basis, just goes out of use, and can't reuse, and causes the profligacy of resource.
Summary of the invention
Technical problem to be solved in the utility model is to provide that a kind of operation is simple, construction fast, engineering cost is lower and can reuse remove after the foundation structure of fixed base tower crane of surplus resources.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of foundation structure of fixed base tower crane, comprise braced structures and for supporting the support platform of placing fixed base tower crane, described braced structures is comprised of four steel columns of imbedding in the soil body, described support platform is the steel platform, the top of described steel column is fixedly connected with described steel platform, between adjacent two described steel columns, has been horizontally disposed with at least one horizontal reinforcing girder steel.
Described horizontal reinforcing girder steel is for vertically equally distributed more than two, be provided with the intersection reinforcing steel beam between adjacent two described horizontal reinforcing girder steels on vertical direction, described intersection reinforcing steel beam comprises two cant beams arranged in a crossed manner, and the end of described cant beam is fixedly connected with described steel column.Support between steel column is more firm.
Described steel platform comprises square steel framework and two supporting beams between four drift angles of described square steel framework arranged in a crossed manner, on described supporting beam, is provided with for fixedly laying the mounting base of described fixed base tower crane.Greatly saved the use amount of steel.
The top of described steel column is fixedly connected with the bottom of described square steel framework by bolt.Only need to twist and go bolt detachable, construct very convenient.
The described soil body is provided with for supporting the concrete cushion of basement bottom board, and described steel column, through described concrete cushion, is provided with the flexible isolating pad between described steel column and described concrete cushion.The flexible isolating pad has separated concrete cushion and has contacted with the direct of steel column, convenient and strength-saving while pulling out steel column.
Compared with prior art, the utility model has the advantage of: in work progress, need directly by the bottom of steel column, insert in the soil body and fix, the top of steel column is fixedly connected with the steel platform, can form the foundation structure of fixed base tower crane, therefore work progress is simple, and can effectively improve efficiency of construction, reduce construction cost simultaneously.Steel column only needs to pull out and transport outward by machinery, so unloading process is very convenient and environmental protection, and the device after dismounting is recyclable and utilization again, has greatly saved resource.
