Abstract

The utility model is related to a kind of anchor jacked pile reaction frame support steel bracket structure.It is in isolated footing（Or cushion cap）Planar dimension is smaller, do not possess piling hole punch in the case of, the support steel corbel corresponding to reaction frame is set in side of the base plate, steel corbel quantity can be at two, can also use cooperatively at only one and with the basic straining beam of opposite side.The utility model to set up anchor jacked pile construction under small size basic condition.Steel corbel is not only used to fix reaction frame in the construction stage, and the auxiliary of permanent service stage after piling completes envelope stake function.Compared with routinely increase concrete foundation or cutting piling hole implement two kinds of reinforcement means of anchor jacked pile, the utility model to key dimension strong adaptability, requirement of the reduction to construction machinery, facilitate site operation, shorten duration, reduction cost, reduce to construction environment noise and dust pollution, transformation requirement when more convenient completion is to original base Lack of support.

Description

A kind of anchor jacked pile reaction frame support steel bracket structure

Technical field

The utility model is related to anchor rod static pressure pile driving construction steel corbel, particularly a kind of anchor jacked pile reaction frame support Steel bracket structure.

Background technology

In order to solve the not enough problem of foundation bearing capacity occurred during renovation of building, original base（Or original cushion cap） Transformation is generally required, supplement anchor jacked pile is a kind of method than relatively straightforward raising bearing capacity, and this method requires original basis Planar dimension is sufficiently large to open progress pressing pile construction in piling hole thereon.Current conditions are：Part isolated footing size is smaller, Outer Bottom Plating of the part basis in stake position or post position does not have enough to open piling hole site.

In the case of substrate soil is weaker, foundation bearing capacity need to be such as improved, increase area of base effect is relatively slow and constructs numerous Trivial difficulty, increases new stake for improving bearing capacity more directly effectively.

Even if original basis size meets new piling hole of opening and requires that cutting construction is also more difficult, especially in height of foundation In the case of larger, and cause dust and noise pollution.

The content of the invention

The purpose of this utility model is to provide a kind of anchor jacked pile reaction frame support steel bracket structure, mainly solved The problems of above-mentioned prior art.The utility model causes small size basis to have use anchor jacked pile possibility, big chi The very little basis selection of another more convenient form of construction work more, while improving efficiency of construction, shortening the duration.The utility model Pressing pile construction mode is simplified, the adaptability to original base is good, the scene of reducing cuts the noise and dust of original concrete Pollute, reduce the requirement for pouring novel concrete to plant equipment, preferably solve construction of the pressing pile construction reaction frame to basis It is required that.

To achieve these goals, the present invention is realized in.

A kind of anchor jacked pile reaction frame support steel bracket structure, it is characterised in that：It is passed through in the side on basis Crab-bolt fixes support steel corbel, and sets reaction frame to fix on the basic straining beam of support steel corbel top surface and opposite position Anchor hole, sets anchor jacked pile to be located between support steel corbel and basic straining beam.

Described anchor jacked pile reaction frame support steel bracket structure, it is characterised in that：Corner side on basis is consolidated Surely steel corbel is supported.

Described anchor jacked pile reaction frame support steel bracket structure, it is characterised in that：The support steel corbel, which is set, to be added Strength rib.

Described anchor jacked pile reaction frame support steel bracket structure, it is characterised in that：Crab-bolt is set in basic two sides Put multiple, reaction frame fixes anchor hole and has 4, respectively set on the basic straining beam of support steel corbel top surface and opposite position Put 2.

It should be noted when the utility model is used：

1st, reinforcement location in original basis is measured using reinforcing bar scanning scenograph, it is determined that installing crab-bolt position and drilling.

2nd, steel corbel is made in factory and is molded, and empty position drilling, in-site installation are bored on the basis of correspondence.

3rd, steel corbel is fixed using installation bolt in basic corner, and in the position of the corresponding pressure pile reaction frame of steel corbel top surface 2 fixing bolt hole drillings of completion are put, and other 2 fixing bolt hole drillings are completed in the basic back of offside.

4th, steel corbel and apron piece install pressure pile reaction frame, piling as bearing.

5th, after the completion of pressing pile construction, reaction frame is removed, angle steel is installed using fixed bolt hole in steel corbel top surface and pushes down stake Top, steel corbel and angle steel turn into a part for permanent envelope stake construction.

6th, steel corbel can set ribbed stiffener to ensure upper limb using the transformation of the side wing edge steel of T-steel cut portion half Listrium as reaction frame bearing stabilization.

7th, because positioned at basic corner, its installation bolt can set multiple fixing bolts in the orthogonal two sides in basis.

8th, requirement for anticorrosion, steel member considers galvanizing, and brushing anti-corrosion material in the finished.

The beneficial effects of the utility model are：

1st, the utility model integrated structure mechanics, the mechanics of materials, construction technology, simplify processing anchor jacked pile constructing structure.

2nd, difficulty of construction is reduced, the requirement to plant equipment is reduced.

3rd, shorten the transformation time to a certain degree, reduce cost.

4th, different size original base conditions are adapted to extensively.

5th, implement to add a kind of selection mode of reaction frame support to set up anchor jacked pile.

6th, noise, dust pollution of the reduction construction to surrounding environment.
