Description
Technical field
The utility model relates to the construction foundation working field, particularly a kind of contrary sequence method pile foundation construction steel post positioning and plumbing device.
Background technology
The conventional order of architecture construction is first excavation pit, then from the basis, and successively upwards construction, the supporting that excavation of foundation pit is required belongs to the measure of construction, and each is irrelevant with the underground structure of building.Contrary sequence method is for the conventional order of architecture construction, basement top-down method construction is that the building cover structure, beam, plate, post and the external wall structure that utilize basement is as the braced structures of foundation pit enclosure structure and foundation construction, the hole in horizontal struts system with go along with sb. to guard him the construction that system is from top to bottom carried out basement structure, meanwhile can carry out the construction of superstructure.In the reverse construction stage, when the basis end and vertical structure not yet formed, all structural loads of top were born by steel post in the stake and diaphragm wall, so the positioning and plumbing of steel post is of crucial importance.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of contrary sequence method pile foundation construction steel post positioning and plumbing device is provided, and can position and vertical adjustment contrary sequence method pile foundation construction steel post effectively accurately.
For solving above technical problem, the technical solution of the utility model is: a kind of contrary sequence method pile foundation construction steel post positioning and plumbing device, its difference is: it comprises that integral body is the vertical adjustment frame of cuboid frame construction, the top of described vertical adjustment frame is provided with for the upper vertical adjustment bolt group that steel post is positioned vertical adjustment, the bottom of described vertical adjustment frame is provided with for the lower vertical adjustment bolt group that steel post is positioned vertical adjustment, described upper vertical adjustment bolt group, the bolt quantity of lower vertical adjustment bolt group is four, described upper vertical adjustment bolt group, bolt in the lower vertical adjustment bolt group all circumferentially is crossing distribution around steel post, the length and width height of described vertical adjustment frame is 3.0m * 3.0m * 4.0m, described upper vertical adjustment bolt group is positioned at apart from 0.4-0.6m place, vertical adjustment frame top, and described lower vertical adjustment bolt group is positioned at the 0.4-0.6m place, bottom apart from the vertical adjustment frame.
The contrast prior art, beneficial features of the present utility model is: this contrary sequence method pile foundation construction steel post positioning and plumbing device can position and vertical adjustment contrary sequence method pile foundation construction steel post effectively accurately.
Description of drawings
Fig. 1 is the utility model embodiment structural representation under the use state in the construction of pile foundation steel post;
Fig. 2 is the plan structure schematic diagram of the utility model embodiment;
Wherein: vertical adjustment bolt group, 3-vertical adjustment frame, 4-steel post, 5-stake hole under the upper vertical adjustment bolt of 1-group, the 2-.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail below by the specific embodiment.
Please refer to Fig. 1 and Fig. 2, the utility model embodiment contrary sequence method pile foundation construction steel post positioning and plumbing device, it comprises that integral body is the vertical adjustment frame 3 of cuboid frame construction, the top of described vertical adjustment frame 3 is provided with for the upper vertical adjustment bolt group 1 that steel post 4 is positioned vertical adjustment, and the bottom of described vertical adjustment frame 3 is provided with for the lower vertical adjustment bolt group 2 that steel post 4 is positioned vertical adjustment.
Preferably, the bolt quantity of upper vertical adjustment bolt group 1, lower vertical adjustment bolt group 2 is four, and upper vertical adjustment bolt group 1, lower vertical adjustment bolt group 2 all circumferentially are crossing distribution around steel post 4.
The using method of the utility model contrary sequence method pile foundation construction steel post positioning and plumbing device is: after the complete and reinforcing cage of pile hole construction is transferred and put in place, with crane vertical adjustment frame 3 is lifted into 5 tops, a hole, and fix, again with upper vertical adjustment bolt group 1 and lower vertical adjustment bolt group 2 middle hang to stake hole 5 of steel post 4 from vertical adjustment frame 3, then screw up and down total eight bolts from four direction, fix steel post 4.Utilize two transits that the steel post 4 in the vertical adjustment frame 3 is carried out the measurement of position and verticality, after finding deviation, by screwing or unscrew the up-down adjustment bolt, steel post 4 is positioned adjusting, make its verticality and steel post 4 centre coordinates reach design and code requirement.
Upper vertical adjustment bolt group 1 and lower vertical adjustment bolt group 2 have formed the up and down structure of two-layer bolt group, and four bolts of every group are in the same level face and around steel post 4 and circumferentially are crossing distribution; Vertical adjustment frame 3 uses jointly with upper vertical adjustment bolt group 1, lower vertical adjustment bolt group 2 during use.Vertical adjustment frame 3 is according to the dimensions of steel post 4, and length and width are generally 3.0m * 3.0m, high 4.0m; Upper vertical adjustment bolt group 1 is positioned at the position apart from about the vertical adjustment frame 3 top 0.5m, and lower vertical adjustment bolt group 2 is positioned at the position apart from about the bottom 0.5m of vertical adjustment frame 3.
Above content is in conjunction with concrete embodiment further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
