the wall bodies on two sides of the corner post are respectively provided with a plurality of strip-shaped holes which are arranged up and down, two side surfaces on the outer side of the corner post are respectively provided with an outer template, the outer templates on the two sides are arranged in an L shape, and the inner side edges of the outer templates respectively extend inwards to the positions corresponding to the strip-shaped holes arranged on the wall body;

the bar is downthehole to wear to have put the single screw rod subassembly that draws of T type, and the single screw rod subassembly that draws of T type includes the screw rod, connects the dead lever in screw rod one end, sets up butterfly card and the nut at the screw rod other end, and the size of dead lever slightly is less than the size in bar hole, and the dead lever is vertical state card and puts on the wall body at the bar hole back, and the screw rod outwards stretches out the outer wall body and passes the exterior sheathing that corresponds the side and go up the wall body, the nut compresses tightly the exterior sheathing on the wall body through the butterfly card.

Further, the width of the square notch is 60 mm.

Furthermore, one square notch is arranged on every other block.

Furthermore, double faced adhesive tapes are respectively stuck on the adjacent end faces of the wall bodies on the two sides of the corner post.

Further, a release agent is coated on the contact surface of the outer template and the corner post.

The utility model has the advantages that:

the utility model discloses steel reinforcement cage both sides wall body handing-over department's inboard corner border direction of height all laminates each other, has avoided inboard formwork, and it is narrow and small to have solved the interior space of closed pipe shaft, and the potential safety hazard is big, and personnel are not convenient for get into the difficult technical problem who carries out the interior form and prop up and establish.

Meanwhile, in order to meet the connecting strength between the corner post and the wall bodies on two sides, the outer side corner position of the end, located at the corner post, of the multi-skin building blocks of the wall bodies on two sides of the corner post is provided with a square notch, and the adjacent upper skin building blocks and the lower skin building blocks, which are not provided with the square notches, of the wall bodies on two sides of the steel reinforcement cage form a horse tooth rubbing which protrudes outwards towards one end of the steel reinforcement cage, so that the connecting strength between the wall bodies and the corner post is ensured.

The utility model discloses the instrument is simple, and convenient operation has greatly simplified the construction flow, has spreading value.

Detailed Description

As shown in figures 1-4, the utility model discloses a formwork structure of a corner column of a closed type pipe shaft, which comprises four walls 1, a reinforcement cage 2 of the corner column is bound between the walls 1 which are vertical to each other at two sides of the corner position, the walls 1 are built by building blocks in layers along the height direction of the corner column, the inner side wall corners at the joints of the wall bodies 1 at the two sides of the reinforcement cage 2 are mutually jointed along the height direction, square notches 4 with the widths of a and a =60mm are arranged at the outer side corner positions of the wall bodies 1 at the two sides of the corner column, which are positioned at one end of the corner column, every two square notches 4 are arranged on every two building blocks, thereby make 2 both sides wall bodies 1 of steel reinforcement cage 2 not set up adjacent epithelium building block and the hypodermis building block of square breach 4 and form outside convex horse tooth and rub 5 towards the one end of steel reinforcement cage 2, horse tooth raft 5 between 2 both sides wall bodies of steel reinforcement cage between 1 advances and moves back unanimously.

And double-faced adhesive tapes 7 are respectively stuck on the end faces between the wall bodies 1 on the two sides of the reinforcement cage 2, and further, the double-faced adhesive tapes 7 are stuck on the two inner side faces of the square notch 4 of the building block.

A plurality of strip holes 6 which are arranged from top to bottom are formed in the wall bodies 1 on two sides of the reinforcement cage 2 respectively, outer formworks 8 are configured on the two side faces of the outer side of the corner column respectively, the outer formworks 8 on the two sides are arranged in an L shape, and the inner side edges of the outer formworks 8 respectively extend to the positions of the strip holes 6 formed in the corresponding side wall bodies 1.

T type singly draws screw assembly 9 has worn to put in bar hole 6, T type singly draws screw assembly 9 includes screw rod 9.1, connect dead lever 9.2 in screw rod 9.1 one end, butterfly card 9.3 and nut 9.4 of setting at the screw rod 9.1 other end, form T type structure between screw rod 9.1 and the dead lever 9.2, the size of dead lever 9.2 slightly is lighter than the size of bar hole 6, make the dead lever 9.2 that has T type singly draws screw assembly 9 can pass bar hole 6, and be vertical state card and put on the wall body 1 at the bar hole 6 back, the one end that dead lever 9.2 was kept away from to screw rod 9.4 outwards stretches out outer wall body 1 and passes the exterior sheathing of wall body 1 on the corresponding side, nut 9.4 compresses tightly exterior sheathing 8 on wall body 1 through butterfly card 9.3.
