as shown in fig. 1 and 2, a multistage combination formula stagnant water pull rod, including interior pole 4, the outer pole 5 that is located interior pole 4 both ends, fixed waterstop 8 on interior pole 4, interior pole 4 both ends can be dismantled and connect cone 6, the tip of cone 6 is close to interior pole 4, and the big end fixed connection nut 7 of cone 6, outer pole 5 pass nut 7 and can dismantle with cone 6 and be connected.

Example 2:

as shown in fig. 1 and 2, in the multi-section combined water stopping pull rod of embodiment 1, the inner rod 4 is in threaded connection with the conical head 6, and the outer rod 5 is in threaded connection with both the nut 7 and the conical head 6. Set up in the conical head 6 with nut 7 assorted screw thread through-hole, the tip of interior pole 4, outer pole 5 all be provided with screw thread through-hole assorted external screw thread. The conical head 6 is coaxial with the nut 7. The water stop sheet 8 is welded in the middle of the inner rod 4 in the axial direction. The conical head 6 and the screw cap 7 are welded or integrally formed. The nut 7 is a hexagon nut with an internal thread.

The installation process of this embodiment is as follows:

1. and pre-assembling the templates, snapping lines and drilling holes according to the arrangement intervals of the transverse and vertical water stop pull rods calculated by the special construction scheme of the templates, and installing a template on one side.

2. The integral main part inside the water-stopping pull rod which is processed in advance is placed in a wall body steel reinforcement framework, and one end of a conical head and one end of a hexagonal nut penetrate into a template hole.

3. The outer rod is screwed with the exposed screw cap and the conical head of the template surface from the outer side through threads.

4. And installing the other side template, enabling the conical head and the hexagonal nut at the other end to penetrate into the hole of the template, using the conical head as a wall thickness limiter, and installing an outer rod from the outer side.

5. The installation template is horizontal and vertical outer stupefied, passes through outer pole fixed formwork with butterfly card and bolt, can carry out the wall body and pour.

The demolition process of this embodiment is as follows:

1. and when the strength of the wall concrete meets the requirement of form removal, removing the transverse wood ribs, the vertical steel ribs, the bolts and the butterfly cards.

2. And (5) rotatably removing an outer rod which is connected with the conical head thread outside the template.

3. And (5) removing the wall formwork. And clamping the screw cap by using a spanner, and rotationally removing the conical head in the concrete.

4. The disassembled outer rod and the conical head with the screw cap are recovered, cleaned, deslagged, oiled and protected, and used in circulation. It should be noted that the formwork and the water-stop tie bar can be removed after the concrete reaches a certain strength.

5. After the conical head is removed, the conical preformed hole formed on the concrete surface is wetted by water and then is filled and compacted by adopting high-strength cement mortar.

The internal thread screw mouth of the conical head, the internal rod external thread screw mouth and the external thread screw mouth of the external rod are processed and connected according to the requirements of fastening standard parts for common bolt connection. And the water stop sheet on the inner rod needs to be fully welded by adopting carbon dioxide arc welding. The recovered outer rod and the conical head are dismantled, and oil separation measures are needed to prevent pollution during oil feeding protection.

The quality benefit analysis of the embodiment:

the water stop sheet of the waterproof inner rod is fully welded by carbon dioxide arc welding, the welding quality is better than that of a conventional water stop pull rod, and the waterproof effect of the wall body is ensured.

The template locator card on conventional stagnant water pull rod is because little with the pull rod contact surface, and the solder joint is few, causes the open welding phenomenon easily in the work progress, leads to the template to warp, can not guarantee wall body cross-sectional dimension, and this embodiment adopts the cone head as the template locator card, can not produce the aversion condition, has guaranteed wall body quality.

If the conventional water-stopping pull rod is adopted, the overall appearance of the structure is easily damaged when the pull rod on the surface of the structure is cut in the later stage, and the waterproof effect is influenced; in the embodiment, the cutting operation is omitted, so that the overall appearance and the waterproof effect of the structure are improved.

Adopt conventional stagnant water pull rod, the pull rod breakpoint after the pull rod excision is in the structure surface, if rust-resistant treatment is not good, easy corrosion influences the structure and pollutes the wall, and the pull rod breakpoint is located the structure in this embodiment, avoids the corrosion influence.

(II) the ergonomics analysis of this example:

in the installation of the template, the embodiment adopts the combination and installation of a plurality of sections of components, and the construction process is simpler and faster than the construction process of the conventional water stop pull rod;

when the template is disassembled, the outer rod in threaded connection is disassembled in advance in a rotating mode, so that the difficulty in disassembling the template is reduced, the efficiency of disassembling the template is improved, the damage rate of the template is reduced, and the turnover rate is improved;

through actual measurement and calculation of a project site, the water-stopping pull rod of the embodiment can improve about 30% of work efficiency in template installation and template removal, and directly saves the construction period.

(III) analysis of economic benefit in the present example

The water-stopping pull rod, the outer rod and the conical head can be repeatedly used in a turnover mode, and cost is directly reduced. Compared with the conventional water stop pull rod, the procedures of cutting off the exposed pull rod after the mold is removed, polishing the break point, performing waterproof treatment on the break point and the like are omitted, the cost is reduced, and the construction period is shortened. Through actual measurement and calculation of an engineering site, compared with a conventional water stop pull rod construction process, the high-strength multi-section combined water stop pull rod can save about 5 yuan.
