Building or structure bulk migration device
The utility model relates to a kind of bulk migration to building or structure, particularly is suitable for the building of multispan high-rise frame structure or the bulk migration device of structure.
Fixed buildings or structure (to call the migration thing in the following text) have bulky and quality heavily waits intrinsic propesties, and it is carried out bulk migration be difficult to realize with existing lifting or carrying mechanism, so, to the migration of moving thing specific method and device should be arranged.For this reason, China Construction Industry Press in April nineteen eighty-three publish " 22 chapters the 8th joint " migration of works " in the Foundation Design handbook has been done more detailed introduction, the technology that its adopts is to be provided with and to be used to hold up concrete or the shaped steel joist that whole building moves thing in the migration owner body zone that is connected with former basis, the joist bottom is provided with round roller bar system and the rail beam of walking track is provided for circle roller bar system, and the system of putting more energy into that is used for mobile building, generally this system of putting more energy into generally adopts hydraulic jack and hoist engine.
Above-mentioned moving apparatus can only be applicable to the migration thing of bottom frame or brick mix structure, and for high level, particularly the migration for the multispan high-rise frame structure then is difficult to realize bulk migration.At first, the load of every support column of multispan high-rise frame structure migration thing is the hundreds of ton at least, several at most kilotons, and heavy support column easily makes joist subside or ruptures as simply holding up with concrete or shaped steel joist, causes unthinkable consequence; And at present also be difficult to find the joist that can hold up heavy like this thing; Secondly,, but the migration thing can not be formed the whole machine balancing system, when push-and-pull migration thing, be difficult to each position of migration thing is all imposed uniform power, may cause the fracture of migration owner body with conventional device even joist can hold in the palm the over-expense dagger.Promptly use the migration thing of the high-rise brick mix structure of this kind device migration, also be prone to above-mentioned phenomenon of rupture.
Task of the present utility model provides a kind of to building or structure bulk migration device, it is by carrying out force analysis to building or structure load-bearing rod member, and definite device that disperses off-load, can overcome above-mentioned weak point, can easily the migration thing be moved to the precalculated position again.
The utility model comprises and is convenient to move the ground-engaging element system that thing moves and frictional force is less, with be arranged on ground-engaging element system bottom and lead to the rail beam on new basis, strange land, and the system of putting more energy into that is used for push-and-pull migration thing, and also comprise the grit system that is arranged on ground-engaging element system top, and the off-load post that can conveniently install or remove between each layer of migration thing support column is set in case of necessity.
Above-mentioned grit system is that each support column is watered the grit system that builds up for the migration thing of frame construction, and also is provided with linking beam between each grit.And move thing for brick mix structure is that load bearing wall is watered the grit system that builds up, and is provided with steel bar stress between the support column of the masonry of this grit and migration thing or load bearing wall.
Above-mentioned off-load post also is provided with plate for convenience detach in the top up and down.
Because the device to migration thing employing off-load post allows the migration thing increase auxiliary stressed member, forms the balance and stability of stressed member system after the off-load once more, make the migration thing form a stable whole, secondly, it can disperse the load of weight body, and making grit hold up heavy migration thing becomes possibility.In addition, the off-load post also can repeatedly use, and can reduce moving costs.
Below in conjunction with drawings and Examples the utility model is elaborated.
Accompanying drawing 1 is that the utility model installs moving apparatus rear section section schematic appearance.
Referring to Fig. 1, the part appearance structure of equipment therefor when it provides a frame construction migration thing migration, its below is the new rail beam of laying 3 that is used for ground-engaging element 2 system's run trace, it selects for use shaped steel and steel plate to make, and is perhaps built by steel concrete to form.Require straightly when rail beam 3 is laid, the new basis of its terminal and relocation site joins, and whole lotuses that this new basis fully can the load bearing migration thing cut, as the permanent basis of moving thing.What rail beam 3 tops were provided with is to be convenient to the ground-engaging element 2 that building moves, and this ground-engaging element can be by interior pouring concrete, and two adds stifled round roller bar construction, and the big I of circle roller rod is determined according to the whole loads that can bear the migration thing.What be installed in ground-engaging element 2 system tops is grit 1 system that is used to hold up whole building migration thing, and it is by cutting a hole hair to former support column 5, and operations such as tick slot are watered grit 1 system that builds up at former support column 5 peripheries, are provided with linking beam 11 between adjacent two grits 1.Be provided with connecting reinforcement in the masonry of grit 1 and between the support column of migration thing or load bearing wall.And be that the load bearing wall periphery is built grit to the migration thing of brick mix structure, its principle and frame construction migration thing are basic identical, no longer explain here.
For the high-rise migration of multispan thing, at first should calculate the load of every support column, auxiliary off-load post 4 is installed between adjacent two support columns 5 then.When off-load post 4 was installed, top or top installation and the corresponding plate 41 in its cross section thereon down were so that conveniently take off off-load post 4 after migration.Off-load post 4 should begin successively to install downwards from the upper strata, and the quantity of its installation should be determined by the load that support column 5 is born.
During migration, be placed on grit 1 top of moving thing, as arrow indication position among the figure, draw equably then or elapse and move thing, till making it move on on the newly-built permanent basis with hydraulic jack or hoist engine.
