Detailed description of the invention
Technical scheme of the present invention is further illustrated below in conjunction with drawings and Examples.
Refer to shown in Fig. 1 ~ Fig. 2, jacking support system of the present invention mainly comprise one group of jacking steel support 1, one group of stabilized steel support 2 and be connected to jacking steel support 1 between, jacking steel support 1 and stabilized steel support 2 between and shape all-in-one-piece steel latticework 3.Wherein, described jacking steel supports the piston lower portion that 1 is respectively installed in jack 4a, 4b, and each jacking steel supports 1 and includes several longitudinal direction steel cylinder 5a stacked successively, and is equipped with flanged plate 6a between two longitudinally adjacent steel cylinder 5a and is bolted fixing; Stabilized steel supports the side that 2 are located at jack 4 respectively, and each stabilized steel supports 2 and also includes several longitudinal direction steel cylinder 5b stacked successively, and is equipped with flanged plate 6b between two longitudinally adjacent steel cylinder 5b and is bolted fixing.
Described jacking steel support 1 and stabilized steel support 2 steel cylinder 5a contour, it is highly 1m.
Described steel latticework 3 comprise all jacking steels are supported 1 level and socket to through the first shaped steel bar assembly 3a, jacking steel supported 1 and supports 2 levels to the Second-Type steel pole assembly 3b socketed with jacking steel is supported 1 and support with corresponding stabilized steel the 3rd shaped steel bar assembly 3c that 2 oblique longitudinal directions socket with corresponding stabilized steel, the concrete structure of three is as follows:
The first described shaped steel bar assembly 3a is made up of shaped steel rod member several, and often pair of shaped steel rod member level sockets to through the both sides supporting 1 corresponding steel cylinder 5a in jacking steel, and is bolted on corresponding flanged plate 6a.That is, jacking steel supports between several steel cylinder 5a of 1 same layer, sockets to through by a pair shaped steel rod member level being located at its both sides, and shaped steel rod member is bolted on the flanged plate 6a of same layer steel cylinder 5a.
Described Second-Type steel pole assembly 3b is made up of several shaped steel rod member, and each shaped steel rod member level supports 1 steel cylinder 5a to drawknot in jacking steel supports between the steel cylinder 5b of 2 with corresponding stabilized steel, and is secured by bolts on corresponding flanged plate 6a, 6b.It should be noted that, jacking steel support 1 and stabilized steel support the corresponding relation between 2, can be one to one, also can be two to one or other corresponding relations, shown in Fig. 1 is that efficiency ratio is preferably three to one, that is every three jacking steels support a 1 corresponding stabilized steel and support 2, and therefore, three steel cylinder 5a that the steel cylinder 5b that each stabilized steel supports 2 supports 1 with it with the jacking steel that layer is corresponding respectively by three shaped steel rod members carry out level to drawknot.
The 3rd described shaped steel bar assembly 3c is also made up of several shaped steel rod member, the upper steel cylinder 5a that the oblique longitudinal drawknot of each shaped steel rod member supports 1 in jacking steel supports between next steel cylinder 5b of 2 with corresponding stabilized steel, and is secured by bolts on corresponding flanged plate 6a, 6b.
Adopt the method for supporting concrete steps of this jacking support system as follows:
A. needing, bottom the building 7 of jacking, one group of jack 4 is installed, and the piston of jack 4 is arranged down, at piston base stacked contour steel cylinder 5a respectively, and arrange flanged plate 6a at the stacked place of steel cylinder 5a connected by bolt, 1 is supported to form one group of jacking steel, in Fig. 28 is distribution beam, and 9 is jacking counter-force basis;
B. at the stacked contour steel cylinder 5b of the downside of each jack 4 difference, and arrange flanged plate 6b at the stacked place of steel cylinder 5b connected by bolt, supports 2 to form one group of stabilized steel;
C. adopt shaped steel rod member that the steel cylinder 5a that jacking steel supports 1 is socketed reinforcing together by level to through;
D. adopt shaped steel rod member jacking steel is supported 1 and stabilized steel support steel cylinder 5a, 5b corresponding to 2 by level to socketing together with reinforcing;
E. adopting shaped steel rod member jacking steel to be supported 1 passes through together with oblique longitudinal drawknot reinforces with stabilized steel steel cylinder up and down 5a, 5b supported corresponding to 2, make jacking steel support 1 and stabilized steel support 2 between shape all-in-one-piece steel latticework 3 form.
In steps A and B, the height of described steel cylinder 5a is 1m.
In step C, between same layer each steel cylinder 5a that described jacking steel supports 1 all by a pair shaped steel rod member level to the through both sides socketed in steel cylinder 5a, and be secured by bolts on corresponding flanged plate 6a, namely every stacked one deck jacking steel supports the steel cylinder 5a of 1, namely carries out level and sockets to through.
In step D, described jacking steel support 1 each steel cylinder 5a and stabilized steel support 2 with layer corresponding steel cylinder 5b between all by shaped steel rod member level to socketing and being secured by bolts on corresponding flanged plate 6a, 6b, namely every stacked one deck stabilized steel supports the steel cylinder 5b of 2, and the corresponding steel cylinder 5a just supporting 1 with the jacking steel of same layer carries out level to drawknot.
In step e, described jacking steel support 1 each steel cylinder 5a and stabilized steel support 2 times one decks corresponding steel cylinder 5b between be all secured by bolts on corresponding flanged plate 6a, 6b by the oblique longitudinal drawknot of shaped steel rod member, namely every stacked one deck stabilized steel supports the steel cylinder 5b of 2, also needs the corresponding steel cylinder 5a supporting 1 with the jacking steel of last layer to carry out rake to drawknot.
By step C ~ E, form steel latticework 3 form, make jacking steel support 1 and stabilized steel supports 2 between formed integrally, thus become the higher jacking support system of a resistance to overturning.
In sum, adopt jacking support system of the present invention and method for supporting, there is following advantage:
1, to build in peace engineering the normal steel cylinder, shaped steel, flanged plate etc. used for stock, socket mutually fixing to two groups of stacked steel cylinders, formed a kind of completely newly and effective jacking support system, structure is simple, easy construction, excellent.
2, by setting that stabilized steel supports, effectively can control jacking process cross the horizontal component of middle appearance and cause top heavy loading object run-off the straight, effectively ensure that the safety of top heavy loading object, thus also effectively ensure the structural safety in jacking, and enable the building of jacking realize rising, becoming slope, decline, correction by the program that people envision, do not reduce the effect of building using function after reaching jacking.
3, alternately jacking is not only applicable to; be equally applicable to conventional raising method (by group jack 4b of in Fig. 2 as temporary support); can also be used as in reinforcing or repair the provisional operator guards in work progress to building, be kill two birds with one stone.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the present invention is described, and be not used as limitation of the invention, as long as in spirit of the present invention, all will drop in Claims scope of the present invention the change of the above embodiment, modification.
