Description

A kind of grid ground-connecting-wall joint design
Technical field
The utility model relates to ground-connecting-wall joint design, particularly relates to grid-like ground-connecting-wall joint design.
Background technology
Diaphragm wall to be interconnected by joint by unit groove section one by one and to form, and the quality of joint is directly connected to total quality and the result of use of body of wall, is more related to the economic benefit of engineering.
Conventional joint form mainly contains snap close union, steel plate for sealing water joint and reinforced concrete prefabricated joint etc.It is simple that snap close union has construction technology, short construction period, and cost is low, do not need to take the advantages such as larger place, but its shortcoming to transmit moment of flexure, axle power and shearing, from great, need merogenesis to make, need take effective sealing concrete side pressure measure, stagnant water effect is poor; It is fast that steel plate for sealing water joint has speed of application, structural strength and good rigidity, moment of flexure and shearing can well be transmitted, stagnant water effect is relatively better, do not need the advantages such as the side pressure of consideration filling concrete, its shortcoming is that steel plate consumption is large, and cost is relatively high, require also higher to the construction precision of Plate Welding, joint easily produces concrete and streams phenomenon; It is large that reinforced concrete prefabricated joint has rigidity, overall performance is good, and can transmit moment of flexure, axle power and shearing, construction technology is simple, stagnant water effect is good, substantially without streaming phenomenon, the construction costs advantage such as comparatively plate joint is low, its shortcoming be conduct oneself with dignity larger, during making, occupied ground is larger, fabrication cycle is longer, and during pile extension, required precision is higher, need take effectively to prevent concrete side pressure measure.
Given this, need invention at present badly a kind of easy to make, speed of application is fast, anti-stream effective, the ground-connecting-wall joint system that lateral rigidity is large.
Utility model content
The purpose of this utility model overcomes deficiency of the prior art, provides a kind of easy construction, good seepage-proof property, and lateral rigidity is large, the grid ground-connecting-wall joint design that resistance to overturning is strong.
This grid ground-connecting-wall joint design, comprises i shaped steel, welding T steel, iron sheet, steel plate press strip, junction steel plate, screw bolt and nut; Be symmetrically welded at i shaped steel web midpoint both sides respectively bottom the web that two root beads connect T steel, form king's Zee bar steel Z; On king's Zee bar steel Z side, bottom flange is welded on the outside of first phase wall section distribution reinforcement respectively; Upper bottom flange both sides outsourcing iron sheet, by steel press strip and bolt seal.
As preferably: T steel web and i shaped steel web are both sides fillet weld seam.
As preferably: upper bottom flange and the first phase wall section distribution reinforcement of king's Zee bar steel Z are two-sided welding, junction tight.
As preferably: outsourcing iron sheet, by being tightly connected, makes whole first phase ground-connecting-wall side form a closed system.
The beneficial effects of the utility model are:
(1) can prevent concrete from streaming the second stage of wall intersegmental part during first phase wall section concreting and form residue, good seepage-proof property, efficiency of construction improves obviously.
(2) i shaped steel both wings edge is deep into adjacent wall section respectively, and crotch-shaped is arranged to by the second stage of wall section distribution reinforcement, and enable adjacent wall section form good drawknot, integrally-built stability strengthens greatly.
(3) each component of whole joint design is to be welded as master, fixes with bolt, and simple to operate, cost is lower.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.Although the utility model will be described in conjunction with preferred embodiment, should know, not represent the utility model restriction in the described embodiment.On the contrary, the utility model will contain can be included in attached claims limit scope of the present utility model in alternative, modified and equivalent.
Just be not repeated in the present embodiment such as the processing of present embodiment steel beam column welding procedure technique, reinforcing bar shape and concrete pouring construction technique, emphasis sets forth the embodiment that the utility model relates to.
Fig. 1 is the utility model grid ground-connecting-wall joint design schematic diagram, with reference to shown in Fig. 1, the utility model grid ground-connecting-wall joint design mainly comprises: comprise i shaped steel 4, welding T steel 3, iron sheet 9, steel plate press strip 10, junction steel plate 11, bolt 12 and nut 13.
Before grid ground-connecting-wall first phase ground-connecting-wall section 5 reinforcing cage is transferred, be symmetrically welded at i shaped steel 4 web midpoint both sides respectively bottom the web that first two root beads connect T steel 3, two leg fillet welds height are 6 ~ 9mm, and length is full weld; Form king's Zee bar steel Z; On king's Zee bar steel Z side, bottom flange is welded on the outside of first phase wall section distribution reinforcement 1 respectively, foot welding height 6 ~ 8mm, weld length 450 ~ 500mm; Upper bottom flange both sides outsourcing iron sheet 9, thickness of scale 2 ~ 4mm, seal with steel press strip 10 and bolt 12, steel press strip selects 20mm wide, thick 201 types of 8mm.
During second phase ground-connecting-wall section 8 fabrication of reinforcing cage, crotch processing is carried out to the second stage of wall section distribution reinforcement 6, after first phase ground-connecting-wall section 5 reinforcing cage is transferred, carries out first phase ground-connecting-wall section 5 filling concrete by diaphragm wall Grouting Pipe 15.
After first phase ground-connecting-wall section 5 concrete strength reaches more than 70% of design strength, carry out the second stage of ground-connecting-wall section 8 reinforcing cage and transfer and filling concrete.
