Abstract
The utility model discloses a pile foundation reinforcing apparatus for a current building, comprising an original framework column, an original framework column lower part, and an original framework column lower bearing platform. The pile foundation reinforcing apparatus is characterized in that the periphery of the original framework column is evenly supported by a plurality of newly-added framework column lower parts; the original bearing platform is supported by a newly-added framework column lower bearing platform.
Description
Technical field
The utility model relates to a kind of pile foundation reinforcement field of existing building, and especially existing building is reinforced the part of (seismic hardening).
Background technology
The underpin of existing building is the reinforcing of a great problem of field of reinforcement, especially building pile foundation always, does not also have ripe Scheme of Strengthening at present at home.The reinforcing of building pile foundation mainly is not have reliable construction technology and otherwise effective technique measure to ensure.Not only cause waste, prolongation engineering time, the increase construction cost of manpower, also bring construction safety hidden danger easily.This patent has solved the difficult problem on technology and the construction technology effectively.
The utility model content
The utility model technical problem to be solved is mainly to solve the existing pile foundation hypodynamic problem of carrying of (comprising stake and cushion cap).
The utility model adopts following technical scheme:
Pile foundation reinforcement device under a kind of existing building; Comprise under original frame column, the original frame column and cushion cap under original frame column; It is characterized in that: be supported with under several newly-increased frame columns being uniformly distributed with all around of original frame column, and be supported with cushion cap under the newly-increased frame column under original cushion cap.
The beneficial effect of the utility model is:
The utility model has adopted technique scheme to the problems referred to above, has both satisfied the instructions for use of engineering, and it is also very simple to construct, and most importantly degree of safety has had guarantee.
Description of drawings
Fig. 1 is the plan view of the utility model;
Fig. 2 is the sectional drawing of the line 1-1 among Fig. 1.
Wherein:
The original frame column of 1-, under the original frame column of 2-, cushion cap under the original frame column of 3-, under the newly-increased frame column of 4-, cushion cap under the newly-increased frame column of 5-.
The specific embodiment
According to embodiment the utility model is done further explain below.
Shown in Fig. 1-2, in this building, arranged 1500 * 1500mm, four pile caps under a certain post, 250 * 250 preformed piles, bearing capacity of single pile are 100KN, altogether 400KN.But after changing the top function of use, this cushion cap need bear the load of 1200KN, and obvious original cushion cap and stake all can't be born far away.For this reason, around original, being uniformly distributed with increases by 12 root piles, and diameter is 300mm, and the bearing capacity of every root pile is 100KN, and 1200KN sets up a new cushion cap simultaneously under original cushion cap altogether.
Construction technology: around original cushion cap, reach the bottom and dig 1000mm with under the manual method; Squeeze into the root pile that mend the back with machinery earlier, former cushion cap bottom surface is cleaned out the brushing interface treating agent with artificial then; Pour into a mould new cushion cap; The venthole of 2 Φ 20 of water brill on original cushion cap makes new cushion cap concrete and former cushion cap concrete combine closely co-operation simultaneously.
Before cushion cap excavation, should carry out the interim reinforcement measure of original pillar earlier, when the concrete strength of waiting to increase newly cushion cap reaches design strength, can remove interim reinforcement measure.
Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the embodiment of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation and changes.Here can't give exhaustive to all embodiments.Conspicuous variation that every technical scheme that belongs to the utility model is amplified out or change still are in the row of the protection domain of the utility model.
