Braced structures and method for supporting thereof for the basement reinforcing of hoist basis of the present invention, has easy construction, duration is short, the advantage that consumables cost is cheap, by adopting steel post to be arranged at respectively between the adjacent two layers floor below the hoist basis, and the central axis of each steel post respectively with the central axis of hoist leading truck on same axis, can play the effect on firm support hoist basis.In addition, steel post is subjected to the prestressing force effect, and is more firm than traditional method for supporting, not easily damaged.In addition and since the top and bottom of steel post respectively with corresponding floor between the gap in inlayed pad, the support instability that can effectively prevent temperature or vibration effect to form, dwindled greatly dangerous may.In addition, steel post assembling form is convenient to dismounting, can recycle, and saves resource.
Description of drawings
Fig. 1 is the structural representation of the braced structures that is used for the basement reinforcing of hoist basis of one embodiment of the invention;
Fig. 2 is the structural representation of the steel post of one embodiment of the invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
As shown in Figure 1, this braced structures for the basement reinforcing of hoist basis is used for supporting elevation machine basis 1, and described hoist basis 1 is fixedly set on the floor 6 of basement top, fixedly installs hoist leading truck 2 on the described hoist basis 1.
This braced structures for the basement reinforcing of hoist basis, comprise some steel posts 4, steel post is arranged at respectively between the following adjacent two layers floor 6 in hoist basis, and the central axis of each steel post 4 respectively with the central axis of hoist leading truck 2 on same axis.
Preferably, as shown in Figure 2, each described steel post 4 comprise above steel pipe 41 and below active 42, described steel pipe 41 and described active 42 between detachable fixedly connected.In the present embodiment, fixedly connected by securing member between described steel pipe 41 and described active 42, described securing member is a plurality of rough M24 * 75 bolts and M24 nut.So, can be so that the assembly and disassembly of steel pipe and active head can be beneficial to the recycling of steel pipe and active head simultaneously.
As depicted in figs. 1 and 2, the braced structures that is used for the basement reinforcing of hoist basis of present embodiment comprises that also some being respectively applied to applies prestressed jack 7 to the active head of correspondence, and described jack 7 is arranged at the position of installing corresponding active 42 on the corresponding floor 6 respectively.In the present embodiment, adopt two jack 7, by the application of force of 7 pairs active 42 on jack, make the top and bottom of steel post 4 head on corresponding floor 6 respectively.
Preferably, the contact position of described steel post 4 and corresponding floor 6 arranges some pads respectively, can tamp space between the corresponding floor 6 in steel post 4 top and bottom by pad, makes that whole braced structures is more firm.
As depicted in figs. 1 and 2, the method for supporting that is used for the basement reinforcing of hoist basis of present embodiment comprises the steps:
During construction, described hoist basis 1 is fixedly set on the floor 6 of basement top, fixedly installs hoist leading truck 2 on the described hoist basis 1.Determine the position that steel post 4 will set up then, and carry out tangible mark, to guarantee that steel post 4 and hoist leading truck 2 central axis are on same axis.Measure the length of good required steel post 4, the equipment of steel post 4 is installed in configuration, and steel post 4 hookup wires are checked at the scene, at last steel post 4 each assembly is installed, and is about to Φ 609 * 12 steel pipes 41 and is connected with the M24 nut with active more than 42 rough M24 * 75 bolts.
Then, required lifting position boring on floor 6, reeve in the hole, differential chain block is installed in lower end at two Pin channel-section steels 3, wherein, and described differential chain block (differential pulley), be also referred to as chain block, it is a kind of laborsaving lifting appliance that forms with wheel shaft and movable pulley combination.After steel post 4 to be assembled is transported to the scene, utilize on-the-spot big machine in reserved opening steel post 4 to be hung underground each aspect, with the sport car transportation by lighter it being transported to each aspect again need support place.Then, use differential chain block that steel post 4 is holded up, make steel post 4 top and bottom respectively facing to corresponding floor 6.Should be noted that, need during lifting to be placed on the lower end with active 42, guarantee follow-up work and remove safety).
Then, use the jack of two QF50 models to promote synchronously, steel post 4 is applied prestressing force, the prestressing force of controlling every steel post 4 is 20KN, make steel post 4 top and bottom be close to corresponding floor 6 respectively, squeeze into gad at active 42 places, with electric welding machine gad and active 42 are welded together.Inlay pad respectively and tamp in the gap between the top and bottom of steel post 4 and the corresponding floor, pad can be steel disc or other sheet metal.
Repeat said process, described steel post 4 all is set between the adjacent two layers floor 6 below the described hoist basis, that is to say, from top to bottom, steel post 4 needs to push up the base plate 8 of basement always, so can realize the firm support to the hoist basis.
In sum, braced structures and method for supporting thereof for the basement reinforcing of hoist basis of the present invention, has easy construction, duration is short, the advantage that consumables cost is cheap, by adopting steel post to be arranged at respectively between the adjacent two layers floor below the hoist basis, and the central axis of each steel post respectively with the central axis of hoist leading truck on same axis, can play the effect on firm support hoist basis.In addition, steel post is subjected to the prestressing force effect, and is more firm than traditional method for supporting, not easily damaged.In addition and since the top and bottom of steel post respectively with corresponding floor between the gap in inlayed pad, the support instability that can effectively prevent temperature or vibration effect to form, dwindled greatly dangerous may.In addition, steel post assembling form is convenient to dismounting, can recycle, and saves resource.
The above only is preferred embodiment of the present invention, and all equalizations of doing according to claim scope of the present invention change and modify, and all should belong to the covering scope of claim of the present invention.
