Abstract
The utility model discloses an adjustable double-layer jack which comprises a support screw rod, a support plate and an adjustable nut; and two support plates are both arranged on the support screw rod and above the adjustable nut to form an upper support plate and a lower support plate. During construction, the upper support plate and the lower support plate are respectively used for supporting floor slabs and main square-columns of a girder, so that one jack can be used for fixing two positions, thereby reducing the utilization of steel pipes and the jacks, greatly reducing the work load of construction and dismantling, improving the working efficiency, effectively reducing the cost, and is obvious in economical benefits.
Description
Technical field
The utility model relates to technical field of buildings, relates in particular to a kind of support jacking that reinforced concrete girder slab is built that is used for.
Background technology
The jacking of prior art all is single pole list top usually, and promptly the top of support screw bar has only a supporting plate, and the support screw bar is provided with the nut that can regulate height.The support screw bar is inserted in the vertical steel pipe 11 during use, and through the height of the set positions supporting plate of nut on the support screw bar, supporting plate then supports main a tree, used in making timber for boats 8 (see figure 1)s of withstanding beam 6 or floor 7.No matter prior art is fastener type, bowl fastening type, dish button, banana button, chrysanthemum mouth formula, or gate-type frame steel pipe, all is that a steel pipe can only be put a jacking, can only be fixed on during use on the position.And in building structure since beam at the bottom of with floor at the bottom of absolute altitude different; Therefore as shown in Figure 1; Need the bottom of respectively corresponding beam 6 and floor 7 to arrange jacking; Not only increased the use of steel pipe and jacking greatly, and the workload that has greatly increased construction and removed, use cost height and operating efficiency are low.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, provide a kind of can be simultaneously when building at the bottom of the beam with floor at the bottom of the adjustable double-deck jacking that supports of main a tree, used in making timber for boats, with the use of a large amount of saving steel pipes and jacking, and effectively increase work efficiency.
The purpose of the utility model is achieved through following technical scheme:
A kind of adjustable double-deck jacking that the utility model provides comprises support screw bar, supporting plate and adjusting nut; Said supporting plate is two, all is arranged on the support screw bar, regulates the top of nut and constitute mounting plate and bottom plate.During construction, the utility model mounting plate and bottom plate are respectively applied for the main a tree, used in making timber for boats of supporting floor and beam, thereby realize that a jacking fixes two positions.
Further, the said bottom plate of the utility model is movably arranged on the support screw bar, as is socketed on the support screw bar, makes bottom plate to move up and down and rotary oscillation and regulate conversion support position, is provided with the supporting nut below the said bottom plate.
In the such scheme, the two ends of mounting plate can be longer than in the two ends of the said bottom plate of the utility model.
In addition, the said mounting plate of the utility model can be fixed on the top of support screw bar, through the rotational support lead screw can the conversion mounting plate placing direction.
The utlity model has following beneficial effect: use a jacking just can be simultaneously at the bottom of the beam with floor at the bottom of main a tree, used in making timber for boats support; Practiced thrift the use of steel pipe and jacking in a large number; The workload that has greatly reduced construction and removed; Improved operating efficiency, effectively reduced use cost, remarkable in economical benefits.
Description of drawings
To combine embodiment and accompanying drawing that the utility model is done further to describe in detail below:
Fig. 1 is the application sketch map of prior art jacking;
Fig. 2 is one of structural representation of the utility model embodiment;
Fig. 3 is the left view of Fig. 2;
Fig. 4 be the utility model embodiment structural representation two;
Fig. 5 is one of application sketch map of the utility model embodiment;
Fig. 6 be the utility model embodiment the application sketch map two.
Among the figure: support screw bar 1, mounting plate 2, bottom plate 3, supporting nut 4 is regulated nut 5, beam 6, floor 7, main a tree, used in making timber for boats 8, inferior a tree, used in making timber for boats 9, template 10, steel pipe 11
The specific embodiment
Fig. 2～shown in Figure 5 is the embodiment of a kind of adjustable double-deck jacking of the utility model, as shown in Figures 2 and 3, comprises support screw bar 1 and according to last and be arranged on mounting plate 2, bottom plate 3, the supporting nut 4 on the support screw bar 1 down and regulate nut 5.Wherein, mounting plate 2 is fixed on the top of support screw bar 1; Bottom plate 3 is actively socketed on the support screw bar 1, can move up and down and rotary oscillation and regulate conversion support position; The supporting nut 4 be positioned at bottom plate 3 below.
In addition, the two ends (see figure 4) of mounting plate 2 also can be longer than in the two ends of bottom plate 3..
Like Fig. 5 and shown in Figure 6, beam 6, floor 7 are built through main a tree, used in making timber for boats 8, inferior a tree, used in making timber for boats 9, template 10 typings.During use; Support screw bar 1 is inserted in the vertical steel pipe 11; Mounting plate 2 withstands on respectively on the main a tree, used in making timber for boats 8 of beam 6, floor 7 with bottom plate 3, according to the placing direction of the main a tree, used in making timber for boats 8 of beam 6 and floor 7, through rotational support lead screw 1 or bottom plate 3; And the putting position of conversion mounting plate 2 and bottom plate 3, the placing direction of mounting plate 2 and bottom plate 3 can be parallel to each other (see figure 5), also can each other vertical (see figure 6).
