[specific embodiment]
Fig. 1 is a kind of waterproof pull bar through walls, comprise pull bar 1, positioning cap 2 and bolt 3, welding seal plate in the middle of the pull bar 1, there is screw thread 102 at the two ends of pull bar, in Fig. 2 and Fig. 3, positioning cap 2 is a truncated cone-shaped, is provided with small end face blind hole 203 at the small end face center of round platform, be provided with large end face blind hole 202 at the center of large end face, the hole wall of small end face blind hole and large end face blind hole is provided with internal thread; In Fig. 4, there is screw thread at the two ends of bolt 3; The two ends screw thread 102 of pull bar is threaded with 2 positioning caps, 2 small end face blind holes 203 respectively, and the connecting thread 302 of an end of bolt 3 is threaded with the large end face blind hole 202 of positioning cap 2.
In Fig. 1, for guaranteeing that preventing to drive pull bar 1 when twisting positioning cap 2 rotates, and is provided with the U-shaped curved arc in pull bar central authorities.Also seal plate 101 can be made rectangular slab, can prevent that equally pull bar 1 from rotating.
When making, present embodiment must note following 5 points:
(1) positioning cap 2 adopts steel ingots to make, and dashes at the rear portion of large end face and to mill the dark blind hole 201 of 3 10mm that diameter is not less than 5mm, so that clip the sunken orifice plate positioning of rotating cap of customization and with its dismounting (Fig. 2,3) with spanner.
(2) small end face of positioning cap 2 dashes the silk mouthful length that extract at the two ends mill the screw degree of depth and pull bar 1, should strict control, guarantee to meet the structural section design size after template is installed.
(3) bolt hole at the large and small end face of positioning cap center should be according to both forward and reverse directions towards thread milling, in case install or when removing bolt 3 positioning cap 2 follow and turn.
(4) the pull bar 1 usefulness diameter round steel that is not less than 12mm is made, and the lateral pressure that its diameter should produce according to pull bar arrangement pitch, concreting etc. is determined, especially needs to check the shear behavior technical data of two terminal filament mouths.Seal plate 101 usefulness diameters are not less than 80mm, and thickness is not less than the steel plate of 3mm and makes.Must full weld between seal plate 101 and the pull bar 1.
(5), dash at the connecting thread that exposes an end 301 places of bolt 3 and to mill out the long oval groove of 20mm for ease of screwing up with a wrench or unscrewing being connected of screw rod 3 and positioning cap 2.
The installation and removal of pull bar through walls:
(1) pull bar through walls is installed
As shown in Figure 5, when mounted, the connecting thread 301 of bolt 3 one ends is passed template 4 and the perpendicular rib 401 of flitch is equipped with at the template back side, again from and the perpendicular rib 401 staggered 2 steel pipe cross ribs 402 of flitch between pass, be connected with nut 6 by the centre bore on the billet 5, the other end of pull bar through walls equally with side template is connected by preceding method, with waterproof pull bar through walls the template of body of wall both sides is fixed like this.
The thickness of billet 5 is not less than 3mm among Fig. 6, and length and width all is not less than 80mm.
(2) pull bar installation procedure through walls
After each unit construction moulding of a upright side template → with pull bar through walls, penetrate opposite side template → adjustment side form verticality → again from upright template opposite insertions → pull bar through walls and tighten → reinforcing of two side forms with the thick steel plate cushion block of 5mm on the bolt sleeve of common wrench after with the opposite side template.
(3) the dismounting operation of the bolt 3 of pull bar through walls and positioning cap 2
Tightening nuts 6 → dismounting bolt 3 → dismounting side form reinforcement system → dismounting side form → side form → positioning cap 2 → positioning cap 2 place the grooves of back-outing removed of moving away are handled.
(4) pull bar through walls is installed and is removed points for attention:
Should be on the silk mouth when being connected between positioning cap 2 and pull bar 1, the bolt 3 coating butter, and with butter shutoff positioning cap aperture, both guaranteed to turn easily between positioning cap 2 and pull bar 1, the bolt 3, and can prevent that again concrete from will infiltrate in the positioning cap aperture, influence the dismounting of positioning cap 2.
Positioning cap 2 external surfaces should the brushing release agent, is that the positioning cap of back-outing is created convenience.
The working procedure that positioning cap 2 grooves are filled up: remove the pea gravel concreten of positioning cap 2 → inwardly fill up 10mm waterproofing unction → be with micro-expanding agent at groove inner face brushing concrete interface agent → tamp with the major part writing brush and screeding and compaction → with the together maintenance of wall concrete.
