Abstract
The utility model discloses an underground continuous wall joint of a double-web I-beam structure. The underground continuous wall joint comprises two parallel flanges and two V-shaped webs arranged between the two flanges, the two web plates are symmetrical, and a V-opening of each web faces inwards. The drawback of high construction difficulty due to the fact that a fastener tube or a joint box is adopted in existing underground continuous wall construction is overcome, the underground continuous wall joint is convenient for construction, reasonable in structure and high in adaptability and has higher shear bearing capacity than the prior art, and structural integrity of slotted section connection and anti-permeability stability of an underground continuous wall are improved by the aid of the joint.
Description
Technical field
The utility model relates to diaphragm wall Construction Technology.
Background technology
Diaphragm wall is the underground structure being coupled together by joint by a plurality of unit body of wall.Due to construction apparatus and technological reason, in work progress, first carry out first phase unit wall construction, then carry out the second stage of wall element construction, one, the second stage of unit wall section connects by joint.In existing technology, between diaphragm wall segmentation body of wall, be connected with multiple heteroid type of attachment.According to different requirements, can use hinged or rigidly connect, as the hinged locking notch pipe that has, what rigidly connect has punched steel plate joint, H shaped steel joint and a cross slab inserted sleeve.Due in traditional underground continuous wall connector, generally do not need to bear larger shearing, adopt locking notch pipe or cross slab joint to get final product engineering demands.But in some large scale structure processes, the joint of diaphragm wall need to bear great shearing, existing conventional construction engineering method and joint cannot meet its shearing resistance requirement.
Utility model content
technical problem:the utility model provides a kind of concrete impermeabilisation ability and stronger shear resistance preferably, is easy to the underground continuous wall connector of making and installing simultaneously.
technical scheme:underground continuous wall connector of the present utility model, is two web i iron configurations, comprises two blocks of wing plates be arrangeding in parallel, is arranged on two blocks of webs between two blocks of wing plates, and web is V font plate, and two blocks of webs are symmetrical arranged, and the V word opening of web is inside.
In the utility model, web is connected and composed by two flat boards, and two dull and stereotyped junctions are the broken line of V font plate, and the broken line of web is parallel with wing plate.
In a kind of preferred version of the present utility model, two writing board shapes, measure-alike of web, broken line is positioned at the midline of web.
In a kind of preferred version of the present utility model, the knuckle of the V word opening of web is 120 °.
beneficial effect:the utility model compared with prior art, has the following advantages:
(1) joint has higher side direction bending resistance and shear stiffness;
(2) joint is connected more firm with reinforcing cage;
(3) there is better anti-permeability performance.
Underground continuous wall connector is to connect the successively important component of two diaphragm walls of construction, and underground continuous wall connector not only requires to be connected firmly, and also requires to have good anti-permeability performance.Original underground continuous wall connector is limited because of I-shaped steel joint frange plate width, can not reach the effect that is all rigidly connected, and especially in deep-foundation pit engineering, is easy to occur that underground continuous wall connector place occurs crack and causes the reduction of shear behavior and anti-permeability performance.Be compared with the prior art, the utility model has knuckle because of web, the shape of binding reinforcement cage joint, make the utility model I-shaped steel joint reinforcing cage of the click joint left and right sides better in the situation that of i iron wing plate limited length, improve integral rigidity, make diaphragm wall one, the second phase connects more solid and reliablely, greatly improve impermeabilisation ability and the shear resistance of diaphragm wall, and be easy to manufacture and install.
Accompanying drawing explanation
Fig. 1 is schematic cross-section of the present utility model.
Fig. 2 is volume rendering schematic diagram of the present utility model.
Fig. 3 is front elevational view of the present utility model.
Fig. 4 is top perspective view of the present utility model.
In figure, have: first phase reinforcing cage 1, wing plate 2, the second stage of reinforcing cage 3, web 4.
The specific embodiment
With reference to figure 1 ~ Fig. 4, underground continuous wall connector of the present utility model, is two web i iron configurations, comprise two blocks of wing plates 2 be arrangeding in parallel, be arranged on two blocks of webs 4 between two blocks of wing plates 2, described web 4 is V font plate, and two blocks of webs 4 are symmetrical arranged, and the V word opening of web 4 is inside.
Web 4 is connected and composed by two flat boards, and two dull and stereotyped junctions are the broken line of V font plate, and the broken line of web 4 is parallel with wing plate 2.Two writing board shapes, measure-alike of web 4, broken line is positioned at the midline of web 4.The knuckle of the V word opening of web 4 is 120 °.
Implementation method of the present utility model is as follows:
1. prefabricated first phase reinforcing cage 1: the both sides reinforcing bar of one end that first phase reinforcing cage 1 joins with two web i iron configuration joints in manufacturing process must bend up, and crooked angle is advisable with 60 °.Design parameter is determined according to design drawing and site operation situation.The type fabrication of reinforcing cage quantity is 2.
2. prefabricated novel pair of web i iron configuration joint: first determine wing plate 2 width and web 4 height of Novel joint according to design drawing, then Site Welding moulding.When welding web, the knuckle that control web is 120 °.This novel pair of web i iron configuration joint production quantity is that reinforcing cage sum subtracts 1.
3. after the 1st step and the 2nd step complete, first phase reinforcing cage 1 is welded on to web 2 one end, during welding, will guarantees both firmly to link together as requiring.
4. prefabricated the second stage of reinforcing cage 3: the second stage of reinforcing cage 3 left and right two end bars in manufacturing process must bend up, and crooked angle is advisable with 60 °.Design parameter is determined according to design drawing and site operation situation.The type fabrication of reinforcing cage quantity reinforcing cage sum subtracts 2.
5. after the 4th step completes, the second stage of reinforcing cage 3 is welded on to new Novel joint web 2 one end, during welding, will guarantees both firmly to link together as requiring.
6. first phase groove section is installed: the integrally welded member of the first phase reinforcing cage 1 of after the moulding of first phase box cut section, the 3rd step being made and Novel joint is put into groove, then concreting.
7. medial launder section is installed: after this carry out the second stage of groove section excavation, after the second stage of groove section has been excavated, the integrally welded member of the second stage of reinforcing cage 3 that the 4th step is made and Novel joint is put into groove, the process of putting into should be noted that following item: the member that the 4th step is made inserts other one end of the Novel joint of the 6th step without one end of Novel joint.Medial launder section just install according to this step one by one according to.
8. pit section is installed: the reinforcing cage 1 that the 1st step is made directly inserts the other one end of Novel joint, then concreting moulding.
The utility model can make the connection between diaphragm wall more solid and reliable, greatly improves impermeabilisation ability and the shear resistance of diaphragm wall, and is easy to manufacture and install.
