Description
Technical field
The present invention relates to the underground building class, relate to a kind of mounting method for underground continuous wall connector concretely.
Background technology
Diaphragm wall and constructure body structure generally adopt the type of attachment of connector, and to form the overall structure of " unification of two walls ", therefore, the connection rate of connector, quality of connection have just become the key of " unification of two walls " whole force structure.The connector of prior art connects main two the aspect problems that exist: the positioning control deviation that is connector on the ground wall reinforcing cage on the one hand is bigger, does not still have the control of standard standard at present.On the other hand, behind the excavation of foundation pit, the quality of connection problem of connector and agent structure reinforcing bar, quality problems such as the corrosion of ubiquity connector, silk tooth destroy and azimuth angle deviation is big, cause the part connector to be connected, the overall structure of influence " unification of two walls " with the reinforcing bar of agent structure.The polygamy reinforcing bar is adopted in design at present usually, and the way that the increase connector is reserved quantity increases whole structural strength.But in practice of construction, often do not have the effect of expection, bring difficulty with being connected on the contrary the installation of practice of construction connector.With certain wide ground of 5M, station wall is example: arrange and put 82 of Φ 32 reinforcing bars in the end, and 60 of connectors (row 40, on arrange 20) down are calculated as follows by no gap layout: 40 * 50+82 * 32=4624mm.If add the rib of reinforcing bar: 82 * 4=328mm.The processing of reinforcing cage reality is arranged very difficult, arrange by designing requirement as main muscle, connector is not just accomplished the regulation that designs, otherwise connector arranges that pressing design code arranges, main muscle does not have position again, consequently bring waste of material, the local leakiness of cast occur hole, wall infiltration point increase, a series of problems such as connector connection.
Summary of the invention
The objective of the invention is according to above-mentioned the deficiencies in the prior art part, a kind of mounting method for underground continuous wall connector is provided, this method is provided with plane supporting structure at the connector place of reinforcing cage, and bar shaped capping panel assembly is set in connector termination direction along the line, to solve problems of the prior art.
The object of the invention realizes being finished by following technical scheme:
A kind of mounting method for underground continuous wall connector comprises diaphragm wall reinforcing cage, a plurality of connector, it is characterized in that this method adopts following steps: at first at reinforcing cage control connector absolute altitude place, horizontal fixed connects positioner; Connector is ridden against on the positioner surface afterwards; After finish the location, connector is fixedlyed connected with positioner.
In the described mounting method, after finishing connector and positioner is fixedlyed connected, more a plurality of connectors are closed in the same capping.
The surface that contacts with connector on the positioner is the plane.
The distance that positioner protrudes from surface of reinforcing cage equates with the height that connector stretches out surface of reinforcing cage.
What positioner adopted is angle steel, and connector rides against on the plane of angle steel.
Advantage of the present invention is, simple in structure, save the engineering material expense, and operating personnel's practical operation operation is simple, easy construction, in the quality of connection that has improved ground-wall connector and agent structure master muscle greatly, reduced engineering cost, the connector accurate positioning can guarantee that groove reaches 100% with the serviceability rate that the excavation cutter reveals connector under the reinforcing cage.
Description of drawings
Accompanying drawing 1 is connector of the present invention and capping mounting structure schematic diagram thereof;
Accompanying drawing 2 is connector of the present invention and capping installation transversary schematic diagram thereof;
Accompanying drawing 1 is connector mounting structure schematic diagram of the present invention;
Accompanying drawing 4 is the A-A generalized section of accompanying drawing 1.
The specific embodiment
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
Shown in Fig. 1-4, label 1-4 represents respectively: reinforcing cage master muscle 1, connector 2, capping 3, angle steel 4.
Present embodiment comprises diaphragm wall reinforcing cage 1 and a plurality of connector 2 that is connected on the reinforcing cage 1, before connector 2 welds on reinforcing cage 1 and fixes, just must connector 2 first positioning control are good, and then welding is fixing.General earlier at reinforcing cage 1 control connector 2 absolute altitude places, horizontal spot welding is as the angle steel 4 of positioner, the height control of connector 2 is standard with the sideline of angle steel 4, connector 2 rides against on the plane of angle steel 4, the welding of back, location is fixing, and the contact surface with connector 2 on the angle steel 4 is a plane contact.To connector and the non-perpendicular connector location and installation of ground wall, adopt card hornwork positioning instant to finish.What positioner adopted is L40 * 3 angle steel 4, and the distance that angle steel 4 protrudes from reinforcing cage 1 surface equates with the height that connector 2 stretches out reinforcing cage 1 surface.
Because above-mentioned operation has adopted positioner control; the height control deviation that is positioned at connector 2 on the reinforcing cage 1 is not more than 2mm; therefore after the independent capping of connector 2 is screwed to the position; bar shaped capping 3 is inserted along the line direction of connector 2; when cutter ground wall topping, the topping of connector section also can be strip of sheet and fall down like this.
It is alternative that bar shaped capping 3 is adopted the aluminium color steels to do to be in strip, and along connector 2 line direction cappings, thin wire is tightened.
Behind connector 2 location, increase the big capping 3 of bar shaped and prevent that connector is destroyed in lifting groove and cutter hair ground wall process.
Connector locating effect on the present embodiment reinforcing cage: basically identical before the height of connector on the reinforcing cage plane controlled situation and gone into groove, whole structure is flat, neat, straight, Deviation Control is desirable.
Connector capping effect along the line: cutter hair ground wall behind the excavation of foundation pit, in the line direction along connector, concrete cover is into strip of sheet basically and is chiseled out; Chisel the topping of ground wall, connector silk tooth do not occur and cut a hole situations such as bad and corrosion; The installation of the connector after chiseling, the face horizontal line is straight, and the work efficiency of cutter wall and stubborn reinforcing bar is faster and better, and connector is installed the raising that the quality that connects has had matter; Connector connecting reinforcement 100%, that promptly twists is fast, and Si Ya is screwed to the position again.
The ground-wall connector installation quality is controlled, and there is no need to increase the reservation quantity of connector during design.
