Description
Technical field
The utility model relate to a kind of can pass through basement without cushion cap lattice tower crane device, for effectively solving the technical problem that tower crane passes through basement bottom board, floor and top board, belong to technical field of building construction.
Background technology
Need to design and arrange job site layout plan the early stage of building operations, and the layout of big machinery is a most important content in the layout of job site, tower crane is as the conventional horizontal vertical Transport Machinery in job site, particularly crucial when layout, the factor that the reasonable Arrangement of tower crane need to be considered is a lot, such as: the shape of the coverage of tower crane, the environment of periphery, proposed building and structure types, tower crane from the distance of building and with the distance in material stockyard, factors such as the installation of tower crane and dismounting conditions.Therefore often can encounter the condition restricting in order to meet above-mentioned factor, and have to tower crane to be arranged within the scope of outdoor basement.
If in the time of tower crane need to being arranged within the scope of outdoor basement, tower crane has three kinds of ways conventionally, as follows respectively:
The first way is: tower crane concrete cushion cap is placed in below basement bottom board, box out on basement bottom board, floor and top board, wait tower crane to remove later after filling-up hole again.This way soil excavation degree of depth is larger, need to do and go along with sb. to guard him and precipitation temporarily, and the duration is also long, also wants secondary filling-up hole in the future, and base plate and top board easily produce seepage herein.
The second way is: the part using tower crane concrete cushion cap as basement bottom board, tower crane top mark is high equally flat with basement bottom board structural plane top mark height.On basement bottom board, do not need box out, only need box out on basement floor and top board, but base plate reinforcing bar herein should be reserved out before building tower crane bearing platform concrete, and can not replace with the reinforcing bar of tower crane cushion cap, and the reinforcing bar of base plate can not replace the reinforcing bar of tower crane cushion cap.The same soil excavation degree of depth of this way is larger, long in time limit, and top board needs secondary filling-up hole, easily produces seepage, and the reserved difficulty of baseplate reinforcing bar is large in addition, and reserved reinforcing bar also needs to take safeguard measure.Although can save a part of bottom board concrete, tower crane cushion cap surrounding must be done steel plate for sealing water, and easily produces seepage in the future.
The third way is: take Combined tower crane basis, Combined tower crane basis is comprised of bored pile, steel lattice column and concrete cushion cap, more than in general concrete cushion cap is arranged on basement roof.Although this way is without just can the construct concrete cushion cap of tower crane of earth excavation, compared with two kinds of ways above, shortened certain duration, but because the volume of cushion cap is larger, take up room also larger, brought inconvenience to follow-up construction, and this cushion cap also must be removed later, after dismounting, a large amount of building wastes will be produced.
In the time of in tower crane must be arranged in outdoor underground garage, all there is defect in various degree in the way of above three kinds of tower cranes, therefore be necessary to design a kind of novel tower crane to make up above-mentioned defect, solve the technical problem of passing through basement bottom board, floor and top board.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of can pass through basement without cushion cap lattice tower crane device, can effectively solve the technical problem that tower crane passes through basement bottom board, floor and top board, and the duration is short, cost is also lower, on basement bottom board, floor and top board without box out, take formed by integrally casting not stay future trouble, tower crane can not produce building waste while removing yet.
In order to solve the problems of the technologies described above, the technical solution of the utility model be to provide a kind of can pass through basement without cushion cap lattice tower crane device, it is characterized in that: comprise steel lattice column, the upper end of four steel lattice columns is connected with four corner posts of tower crane tower-body standard section respectively, and the lower end of four steel lattice columns is passed described basement and is anchored in four construction reinforced concrete filling piles of described basement bottom board below; Between adjacent steel lattice column, be provided with lacing, between two steel lattice columns of diagonal angle setting, be provided with horizontal cross brace.
Preferably, described steel lattice column is batten plate formula lattice column, and by four equal leg angles, the batten plate by four sides is welded every steel lattice column.
Preferably, the upper end of described steel lattice column is connected with the corner post of described tower crane tower-body standard section by lattice capital steel platform.
Preferably, described lattice capital steel platform comprises the horizontal steel plate of capital, and the horizontal steel plate of capital welds by put more energy into floor and described steel lattice column of triangle, and the horizontal steel plate of capital is connected with the corner post of described tower crane tower-body standard section by bolt.
Preferably, the effective anchorage length of described steel lattice column in described construction reinforced concrete filling pile is not less than 3m.
Preferably, the top mark of described steel lattice column exceeds the high 500～600mm of described basement roof top mark.
Preferably, described steel lattice column and basement have the flaggy intersection of waterproof requirement, the angle steel periphery full weld steel plate waterstop strip of described steel lattice column.
Preferably, described lacing, horizontal cross brace are channel-section steel or angle steel.
Preferably, described lacing is comprised of horizontal lacing and the oblique lacing be located between adjacent two described steel lattice columns.
The pile foundation as tower crane without four construction reinforced concrete filling piles of cushion cap lattice tower crane device employing that can pass through basement that the utility model provides, the non-standard joint that four steel lattice columns form a whole as tower crane by lacing and horizontal cross brace is directly connected with pile foundation, centre no longer arranges concrete cushion cap, the non-standard joint that the various loads of tower crane consist of these four steel lattice columns is directly delivered in pile foundation, by theory, calculate and practical application, all confirmed that this steel latticework pillar tower crane can meet the service load requirement of tower crane completely, safety factor can reach more than 3 times.Secondly, at the basement bottom board and the top board place that have waterproof requirement, the angle steel of every steel lattice column is full weld steel plate waterstop strip around, while building basement structure concrete, steel lattice column is imbedded in concrete, and tower crane cuts off steel lattice column after removing again in the future.Owing to reaching requirement without excavation tower crane and without the intensity of waiting for tower crane bearing platform concrete, therefore tower crane can be installed and come into operation in advance, be conducive to guarantee the construction period.
The device that the utility model provides has overcome the deficiencies in the prior art, takes formed by integrally casting not stay future trouble, not only safety, stable, reliable, and easy construction, versatility is good, has saved reinforcing bar and concrete material, the all right recycling of steel lattice column, also helps and guarantees the construction period simultaneously.
