Abstract
The utility model relates to the underground construction category, in particular to an underground continuous wall connector installation structure, a plane support structure is arranged at a connector location of a steel bar cage, a bar-shaped cover plate device is arranged along the line direction of the connector end; the utility model has the advantages of simple structure, saved construction material cost, easy operation and easy construction process, which can largely improve the connection quality of the underground wall connector and the main bar of the main structure, simultaneously, the construction cost is lowered, the location of the connector is accurate, the perfectness rate of a lower groove of the steel bar cage and the excavation exposure connector can be assured by 100 percent.
Description
Technical field
The utility model relates to the underground building class, relates to a kind of mounting structure 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 purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of mounting structure for underground continuous wall connector is provided, this structure 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 utility model purpose realizes being finished by following technical scheme:
A kind of mounting structure for underground continuous wall connector comprises diaphragm wall reinforcing cage, a plurality of connector, it is characterized in that being fixedly connected with positioner on the subterranean wall reinforcing cage positioner support fixation connector.
Contact surface with connector on the positioner is a plane contact.
The distance that described positioner protrudes from surface of reinforcing cage equates with the height that connector stretches out surface of reinforcing cage.
Described positioner can adopt angle steel, and connector rides against on the plane of angle steel.
Described a plurality of connector is positioned at same capping.
The utility model has the advantages that, 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 the utility model connector and capping mounting structure schematic diagram thereof;
Accompanying drawing 2 is that the transversary schematic diagram is installed in the utility model connector and capping thereof;
Accompanying drawing 4 is the A-A generalized section of accompanying drawing 1.
The specific embodiment
The utility model feature 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.
A kind of mounting structure for underground continuous wall connector that present embodiment relates to, comprise diaphragm wall reinforcing cage 1 and a plurality of connector 2 that is connected on the reinforcing cage 1, be welded with positioner on subterranean wall reinforcing cage 1, this positioner adopts L40 * 3 angle steel 4, angle steel 4 support fixation connectors 2.Connector 2 rides against on the plane of angle steel 4, and the contact surface with connector 2 on the angle steel 4 is a plane contact.
The distance that angle steel 4 protrudes from reinforcing cage 1 surface equates that with the height that connector 2 stretches out reinforcing cage 1 surface a plurality of connectors 2 are positioned at same capping 3.Capping 3 is elongated.
Before connector 2 welds on reinforcing cage 1 and fixes when concrete construction, just must connector 2 first positioning control are good, then welding is fixing.General earlier at reinforcing cage 1 control connector 2 absolute altitude places, level point leg steel 4, the height control of connector 2 is standard with the sideline of angle steel 4, and connector 2 rides against on the plane of angle steel 4, and the welding of back, location is fixing.To connector and the non-perpendicular connector location and installation of ground wall, adopt card hornwork positioning instant to finish.
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.
