Description
Technical Field
The invention relates to the field of section building construction methods, in particular to a method for reinforcing an inner template of an outer wall of a building.
Background
In the construction process of pouring a wall body in a building, an outer formwork and an inner formwork need to be fixed. In order to fix the distance between the inner formwork and the outer formwork, the formworks on both sides are usually fixed by using tie bolts to prevent the formworks from being outwardly spread by concrete during the casting process, which results in the displacement of the formworks.
After the pouring is finished, the split bolts need to be removed, and the original positions of the split bolts are provided with cavities perpendicular to the wall body, so that a cold bridge is formed, and the heat insulation of the wall body is influenced. And the left holes are filled after the split bolts are disassembled. The construction steps are increased, and the construction efficiency is influenced.

s03: tensioning the pull rope by using a pre-tightening piece to tightly press and fix the outer template and the inner template;
s04: and pouring the wall body.
The stay cord is used for replacing the split bolt, on the basis of realizing the fixation of the inner formworks, a cold bridge vertical to the wall body can be eliminated by adjusting the angle of the stay cord, and the stay cord can be directly left inside the wall body, so that the step of dismantling the split bolt is reduced.
Preferably, the pull rope obliquely penetrates through the outer template and the inner template. When the inclined pull rope passes through the wall body, even if a cold bridge appears, the distance of the cold bridge can be lengthened, and the influence on the heat insulation performance of the wall body is reduced.
Preferably, the end part of the pull rope is connected with a threading rod, and the threading rod pulls the pull rope to penetrate through the outer template and the inner template. The difficulty of the stay cord passing through the outer template and the inner template can be reduced through the threading rod, and the construction efficiency of the stay cord is improved.
Preferably, the pretensioning piece is an insertion rod, and the insertion rod is inserted between the outer side of the outer template and/or the inner template and the pull rope. The pretension piece realizes the tensioning of stay cord, makes the position of interior template more firmly difficult the appearance shift.
Preferably, the insertion rod pulls the pull rope in a rotating manner. The pull rope can be screwed up by rotating the inserted bar at the outer side bolt of the outer template or the inner template, so that the pull rope is tensioned, and the inner template is fixed.
Preferably, the inserted link is provided with a plurality of insertion parts with diameters decreasing in sequence along the axis direction, and the diameters of the insertion parts are increased in sequence to realize tensioning of the stay cord. The multi-section inserted rod can increase the diameter of the inserted part by continuous insertion, and tension of the pull rope is realized in a tensioning mode.
Preferably, one end of the inserted bar is provided with a limiting part extending outwards. The limiting part is used for preventing the pull rope from being separated from the inserted link.
Preferably, the limiting part is provided with a notch, and the outermost side of the notch is not more than the outermost side of the inserted bar body. The outer template or the inner template can be pressed close to in breach department, avoids spacing portion and outer template or inner template to interfere to influence the motion of inserted bar.
Preferably, the pull rope is a nylon rope or a glass fiber rope. The nylon rope or the glass fiber rope is light in texture, has enough strength and low cost, and can be used for one time. And the exposed part of the outer side of the wall body can be directly cut off after the pouring is finished, the cavity does not need to be dismantled and filled, and the construction efficiency is improved.
The invention has the following beneficial effects:
1. the stay cord is used for replacing the split bolt, the length of the stay cord passing through the wall body can be increased by changing the angle of the stay cord, the heat transfer speed is reduced, and the influence caused by a cold bridge is reduced;
2. after the pouring is finished, the exposed pull rope can be directly cut off, and the pull rope in the wall body is left in the wall body, so that the processes of removing and filling the cavity are reduced, and the construction efficiency is improved;
3. the stay cord can be tensioned by using the inserted bar, so that the inner template is fixed.
