Abstract
The invention belongs to the prestressed concrete box girder technical field of construction, be specifically related to a kind of bellows and end mould fixing method.A kind of bellows and end mould fixing method, it is characterized in that it comprises the steps: to choose the connecting tube (3) of external diameter less than inside diameter of bel, go up bellows quantity and each the bellows core coordinate position of pressing case beam section at the Side Template (1) of end mould and on Side Template, draw a hole circle (2) with chalk, each hole on Side Template (1) circle (2) is located spot welding and is connected connecting tube (3) then, makes the centre coordinate position of pore of connecting tube (3) corresponding with the centre coordinate position of Kong Quan (2); The end of bellows is enclosed within outside the connecting tube (3), outside, the end of bellows compresses with iron wire again.That method of the present invention has is easy to connect, reduce the characteristics of repairing and damaging.
Description
Technical field
The invention belongs to the prestressed concrete box girder technical field of construction, be specifically related to a kind of bellows and end mould fixing method.
Background technique
The end mould is formed by panel (Side Template), vertical rib and cross rib assembly welding, all adopts between end mould and bed die and the external mold to regulate the screw mandrel support and split bolt is connected.In the prestressed concrete box girder work progress, bellows is fixed with the end mould, traditional way is that (generally being large-scale Sheet Steel Form) cuts the hole on Side Template, then bellows is aimed at corresponding hole on the Side Template, bellows is with outside the traversing through end pattern hole, because in standard was striden, the position of the bellows of each section of every case beam was all inequality, hole site on the Side Template will occur and constantly cut the phenomenon in hole, Side Template can be destroyed maybe and need be repaired; This method of construction can cause the damage of Side Template bigger, and the workload of repairing is big, even can increase the tricks of end mould.
Summary of the invention
The object of the present invention is to provide a kind of easy to connect, bellows and end mould fixing method that reduce to repair and damage.
To achieve these goals, technological scheme of the present invention is: a kind of bellows and end mould fixing method, it is characterized in that it comprises the steps: to choose the connecting tube of external diameter less than inside diameter of bel, on the Side Template of end mould, press bellows quantity and each bellows core coordinate position of case beam section and on Side Template, draw a hole circle with chalk, the spot welding of on Side Template each hole circle place connects connecting tube then, and the centre coordinate position that centre coordinate position and the hole of the pore of connecting tube are enclosed is corresponding; The end of bellows is enclosed within outside the connecting tube, the outside, end of bellows compresses with iron wire again.
At connecting tube external application glue bond one circle soft rubber, soft rubber outside, enclose sponge around one again, sponge is fixed on the connecting tube with thin wire.
The invention has the beneficial effects as follows: adopt each circle place, the hole spot welding on the Side Template to connect connecting tube, operate so conveniently, because this method is not cut the hole on Side Template, so Side Template is close to not damage (also need not repair); Connecting tube adopts spot welding to be connected with Side Template simultaneously, during the demoulding, be easy to Side Template is separated with bellows, and Side Template is injury-free, and Side Template can be repeatedly used.Adopt the internal diameter of the external diameter of connecting tube less than bellows, because connecting tube is littler than bellows, this is convenient to butt joint (easy to connect); When bellows core coordinate and drawn hole circle centre coordinate depart from, because connecting tube is littler than bellows,, little error do not influence connection even taking place yet, significantly reduced the patch work of Sheet Steel Form, the while also alleviates the damaged condition of Sheet Steel Form.Adopt soft rubber, sponge to carry out encapsulation process, cement slurry infiltrates in the bellows in the time of can preventing concrete vibrating.
Description of drawings
Fig. 1 is a fixedly schematic representation of the present invention;
Fig. 2 is the left view (in order to clearly illustrate structure, the part bellows does not draw) of Fig. 1;
Among the figure: 1-Side Template, 2-hole circle, 3-connecting tube (black pipe), 4-soft rubber, 5-sponge, 6-bellows, 7-iron wire.
Embodiment
As shown in Figure 1 and Figure 2, a kind of bellows and end mould fixing method, it comprises the steps: to choose external diameter, and (as: diameter of bellows 6 is 100mm less than the connecting tube 3 of inside diameter of bel, the diameter of connecting tube 3 is 95mm, the length of connecting tube 3 is 50mm), described connecting tube 3 is a black pipe, because black pipe is littler than bellows, this is convenient to butt joint.On the Side Template 1 of end mould, press bellows quantity and each bellows core coordinate position of case beam section and on Side Template, draw a hole circle 2 with chalk, each hole on Side Template 1 is enclosed 2 places spot welding and is connected connecting tube 3 then, and it is corresponding to make centre coordinate position and the hole of the pore of connecting tube 3 enclose 2 centre coordinate position; Only need 3 of connecting tubes (black pipe) be burn-on by the centre coordinate difference of bellows to different sections, operate so conveniently, Side Template is close to not damage (also need not repair).Cement slurry infiltrates in the bellows when preventing concrete vibrating, at first at the thick soft rubber 4 of connecting tube 3 external application glue bonds, one circle 2mm, outside soft rubber 4, enclose thick 10mm sponge 5 again around one, sponge 5 usefulness thin wires are fixed on the connecting tube (black pipe) 3, the end of bellows is enclosed within outside the connecting tube, the outside, end of bellows compresses with 22# iron wire 7 again.
Claims (4)
1. bellows and end mould fixing method, it is characterized in that it comprises the steps: to choose the connecting tube (3) of external diameter less than inside diameter of bel, go up bellows quantity and each the bellows core coordinate position of pressing case beam section at the Side Template (1) of end mould and on Side Template, draw a hole circle (2) with chalk, each hole on Side Template (1) circle (2) is located spot welding and is connected connecting tube (3) then, makes the centre coordinate position of pore of connecting tube (3) corresponding with the centre coordinate position of Kong Quan (2); The end of bellows is enclosed within outside the connecting tube (3), outside, the end of bellows compresses with iron wire again.
2. a kind of bellows according to claim 1 and end mould fixing method, it is characterized in that: at connecting tube (3) external application glue bond one circle soft rubber (4), again outside soft rubber (4) around one the circle sponge (5), sponge (5) is fixed on the connecting tube (3) with thin wire.
3. a kind of bellows according to claim 1 and end mould fixing method is characterized in that: the diameter of described bellows is 100mm, and the diameter of connecting tube (3) is 95mm, and the length of connecting tube (3) is 50mm.
