Abstract
The utility model discloses an underground continuous wall structure for reverse construction method, include: the underground continuous wall main part, enclose purlin and pilaster, the underground continuous wall main part with it connects with the bar planting mode through enclosing the purlin joint bar to enclose the purlin, the underground continuous wall main part with the pilaster is passed through the pilaster joint bar and is connected with the bar planting mode. The pilaster is passed through pilaster joint bar shoving pours the shaping. It has and inserts the reinforcing bar of locating in the contignation of intermediate level to enclose in the purlin anchor. The underground continuous wall main part enclose the purlin and the pilaster connects into a whole through whole the watering of concrete. Pilaster joint bar and to enclose the purlin joint bar be HBR400 level reinforcing bar. The floor determination of position then encloses purlin joint bar determination of position, effectively reduces because of burying the inaccurate later stage problem of bringing of doing over again in a position. See from construction flow, the utility model discloses a structure neither needs the earlier stage embedded bar and ware of plugging into in underground continuous wall, does not also need the later stage chisel to bury the piece except that ground even wall concrete finds, and construction flow has obtained the simplification.
Description
Technical field
The utility model is related to the realm of building construction, espespecially a kind of contrary sequence method continuous underground wall structure.
Background technology
In recent years, it is inverse to make with the extensive use of the increasing of super-sized foundation pit multi-storey basement and " contrary sequence method "
Method has obtained extensive concern and research on building circle.Urban district site coverage is very suitable for greatly using " contrary sequence method " construction, it is neighbouring
Building, subway, underground utilities and the surrounding environment situation sensitive to sedimentation and deformation.Engineering practice shows, main body underground structure
It is combined with foundation pit supporting construction, using reverse construction, can be constructed simultaneously up and down, engineering image, progress is good, shorten and apply
Work total lever factor；Structure level component substitutes that support stiffness is big, and fender body deformation is small, is conducive to surrounding environment and built construction thing
Protection；Fender body, support and column use agent structure, it is to avoid the wasting of resources, the remarkable in economical benefits of engineering；Using envelope
Close, adverse construction method, job site civilization, beneficial to urban construction and environmental protection；The design of main body underground structure more rationally, and has
There is stronger economy.
Although the extensive use that reverse construction is obtained, the treatment of some key nodes is not often reached in practice of construction
Promising result, for diaphram wall and pilaster, encloses the connected mode of purlin, and current Normal practice is horizontal structure when constructing,
Reserved joint bar is set by the length of code requirement to make stage reinforcing bar and plug into use for suitable, subsequently plug into cylinder or wall position
Plugging into the form for mechanically connecting, with adhesive waterproof tape to thread head bag in work progress between reinforcing bar and former reserved joint bar
Wrap up in.There is problems with this construction method：
1st, diaphram wall and pilaster, enclose built-in fitting at purlin connecting node position and absolute altitude it is usually not accurate enough, nothing
Method is smoothed out plugging into, and this is accomplished by the later stage and processes node embedded part again, is seriously delayed construction speed.
2nd, need to carry out ironware in advance and connector is pre-buried, work progress is relatively complicated.
3rd, for the engineering using the larger reinforcing bar of fragility, such as HRB400 grades of reinforcing bar is curved because the fragility of reinforcing bar is larger
Easily it is broken afterwards.In casting concrete, concrete pump vibrates can influence reserved joint bar position so that built-in fitting fails.
The content of the invention
The purpose of this utility model is to provide a kind of contrary sequence method continuous underground wall structure, realize diaphram wall main body with
Pilaster and enclose the connection of purlin.
The technical scheme that the utility model is provided is as follows：A kind of contrary sequence method continuous underground wall structure, including：Underground is continuous
Wall main body, purlin and pilaster are enclosed, the diaphram wall main body is enclosed purlin and be connected in bar planting mode by enclosing purlin joint bar with described, institute
Diaphram wall main body is stated to be connected in bar planting mode by pilaster joint bar with the pilaster.
Connector is connected by the way of bar planting and purlin and pilaster is enclosed, i.e., directly squeezed into agent structure reinforcing bar, this from
The construction method of embedded bar and connector is fundamentally changed, its benefit has four：
First, avoiding situation about need to be constructed again because embedded part position is inaccurate, it is only necessary to dug to floor mark in the earthwork
The height and position turns joint bar hole after eminence, and floor position determines then to enclose the determination of purlin joint bar position, effectively reduces because of embedded part position not
The accurate later rework problem brought.
Second, from construction process, structure of the present utility model both do not needed early stage in diaphragm wall embedded bar and
Connector, it is not required that the later stage, the substantial amounts of ground-connecting-wall concrete that cuts found embedded part, and construction process has obtained larger simplification, applied
The reduction of work difficulty, accelerates construction speed.
Third, the utility model uses joint bar form, it is to avoid embedded bar bends fracture in concreting, or
Being vibrated by concrete pump influences the situation of joint bar position.
Fourth, joint structure is simple, easy construction.
Preferably, the diaphram wall main body is enclosed purlin and is connected with intermediate layer contignation by described, described to enclose purlin
Anchoring has the reinforcing bar being inserted in the contignation of intermediate layer.
Structure of the present utility model is particularly suited for the construction of contrary sequence method intermediate floor connecting node, is connected by enclosing purlin
Connect diaphram wall main body and intermediate floor beam slab.
Preferably, the diaphram wall main body, described enclose purlin and the pilaster connects into one by whole the pouring of concrete
Individual entirety.
One entirety is connected into by pilaster and ground-connecting-wall, preferably realizes that internal force is transmitted, it is ensured that the safety of building.Tool
Body, the pilaster joint bar and purlin joint bar is enclosed for HBR400 grades of reinforcing bar.
The contrary sequence method continuous underground wall structure provided by the utility model, can bring following at least one beneficial effect
Really：
1st, floor position determines then to enclose the determination of purlin joint bar position, effectively reduces because the embedded part position inaccurate later stage for bringing is returned
Work problem.
2nd, from construction process, structure of the present utility model does not both need early stage pre-buried steel in diaphram wall main body
Muscle and connector, it is not required that the later stage, the substantial amounts of ground-connecting-wall concrete that cuts found embedded part, and construction process has obtained larger letter
Change, difficulty of construction reduction accelerates construction speed.
3rd, using joint bar form, it is to avoid embedded bar bends fracture in concreting, or is shaken by concrete pump
Smash the situation of influence joint bar position.
4th, diaphram wall connecting node simple structure, easy construction.
5th, an entirety is connected into by pilaster and ground-connecting-wall, preferably realizes that internal force is transmitted, it is ensured that the safety of building.
