Abstract
The utility model discloses a moving foundation of a hoisting machine. The moving foundation of the hoisting machine is used for a tower crane, a construction elevator and a material machine. The moving foundation of the hoisting machine comprises rectangular concrete blocks identical in size, fixing sleeves are arranged on the four corners of a body in a sleeved mode, and fastening draw cords are arranged between the adjacent fixing sleeves. Prefabricated concrete blocks are adopted by the foundation, prefabrication can be carried out, assembling can be carried out on site, time for on-site construction can be shortened greatly, the foundation can be demounted and used repeatedly, and the cost for demounting the foundation is reduced. In addition, in terms of the fact that the integrality among multiple layers of structures is poor, the fixing sleeves are added to four right-angle positions, the integral stability among multiple concrete block layers can be increased through the arrangement of the fixing sleeves, the adjacent fixing sleeves are connected through the draw cords to form a stressed integrity, the requirement of overall stress is met, and the foundation is made to be firmer and more stable.
Description
Technical field
The utility model belongs to the realm of building construction, is specifically related to the mobile basis for pillar crane, construction elevator, material machine.
Background technology
Lifting appliance is that in construction project, generally to use instrument, the design on lifting appliance basis be to ensure machine security wherein and the normal key link using.At present conventional lifting appliance basis is the fixed basis of cast in situs steel concrete, and principal mode has right-angled intersection beam type, right-angled intersection and square combined type, square plate formula, four jiaos of pier formulas etc.By the research to these bases, find that tradition basis exists following deficiency:
Long in time limit.Remove on basis after foundation dredging, basic making, concrete curing and even tower machine are finished using, all needs to take a long time.Foundation construction, from soil excavation or backfill, reinforcing bar binding, concreting to maintenance, at least needs 15-20 days, and lifting appliance can not be installed operation in time, and the duration is affected.
Expense is high.All need to spend more expense from foundation excavation, basic making, concrete curing, the basis dismounting of finishing using and the treating construction waste on waste and old basis.After lifting appliance transition, need to discarded basis be struck cutter, be processed, cause the significant wastage of manpower and materials.
Utility model content
It is a kind of pre-formed that the purpose of this utility model is to provide, and Assembling and the lifting appliance with good structural stability move basis.
For achieving the above object, the technical solution of the utility model is: lifting appliance moves basis, comprise Rectangular Concrete piece, polylith Rectangular Concrete piece forms the immobilizing foundation of one deck rectangle in same plane, on four angles of described one deck immobilizing foundation, be arranged with fixed cover, between described adjacent fixed cover, be provided with fastening stay cord.
Adopt when technique scheme, this basis adopts precast concrete block, can carry out prefabricatedly, assembles at the scene, can greatly shorten the time of site operation, and can repeat to remove and utilize, and has reduced and has removed basic cost.In addition, poor for the globality between single layer structure or layer structure, therefore increased fixed cover at four right angles place, by being set, fixed cover can increase the resistance to overturning between multiple concrete block layers, by stay cord, adjacent fixed cover is connected to form to a stressed entirety again, reach the stressed requirement of entirety, make more more stable and stronger of basis.
Further, the right angle type corner protector that has at least a fixed cover to be formed by two L-squares, the back side of described L-square is vertically provided with installing plate, and described installing plate is provided with installing hole.
Further, stay cord joint is installed on described fixed cover, one end of described stay cord joint is fixed in installing hole, and the other end is fixed fastening stay cord.Above-mentioned setting can regulate length by stay cord joint, and then tensioning stay cord, makes it produce enough prestretching tensile forces, keeps basic structural integrity.
Further, be provided with many group reinforcing ribs between described L-square and installing plate, every group of reinforcing rib comprises two triangle stiffeners, and two described triangle stiffeners divide the both sides that are located at installing hole.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation that the utility model lifting appliance moves basic embodiment.
Detailed description of the invention
As shown in Figure 1, the utility model lifting appliance moves basis, is made up of the identical Rectangular Concrete piece 1 of shape size, and Rectangular Concrete piece 1 can adopt prefabricated mode to make in advance, on-site consolidation basis of formation.This basis can be divided into the above assembled structure of monolithic, polylith or multilayer, and the every four Rectangular Concrete pieces of multilayer can surround " a returning " font in same plane, and multilayer " is returned " character form structure and stacked up and down basis of formation.The Rectangular Concrete piece 1 of the corresponding adjacent two layers in the position 90 degree phase angles of staggering along the center of " returning " character form structure each other, make the every Rectangular Concrete piece on upper strata, push down the Rectangular Concrete piece 1 of lower floor; On four angles on basis, be provided with right angle fixed cover, wherein have 3 subordinate fixed covers 2 and a main fixed cover 3.The right angle type corner protector that wherein main fixed cover 3 is made up of two L-squares 31, the back side of described L-square 31 is vertically provided with installing plate 32, and described installing plate is provided with installing hole.On main fixed cover 3, stay cord joint 4 is installed, one end of described stay cord joint 4 is fixed in installing hole, and the other end is fixed fastening stay cord 5.Above-mentioned setting can be led to stay cord joint 4 and regulated length, and then tensioning stay cord 5, makes it produce enough prestretching tensile forces, keeps basic structural integrity.
On installing plate 32, offer 3 installing holes, the centre position of position corresponding one deck concrete block layer of each installing hole.One end of stay cord 5 is fixed on stay cord joint 4, and the other end is walked around on the stay cord joint 4 that 3 subordinate fixed covers 2 are connected to the other end.
Above-described is only preferred embodiment of the present utility model, should be understood that, for a person skilled in the art, do not departing under the prerequisite of the utility model structure, can also make some distortion and improvement, for example: the concrete block of every one deck can, by multiple erection method, be organized combinations and also can have between layers more.These also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
