In the step of pouring, pouring agent is input into the pouring holes, and the air holes are communicated with the grooves, so that when the pouring agent overflows from the vent pipes connected with the air holes, the fact that the pouring agent really flows into the grooves can be determined, and the amount and the distribution uniformity of the pouring agent are controlled.

Description

Leakage repairing method for window frame

Technical Field

The present invention relates to a leak repairing method, and more particularly, to a leak repairing method capable of standardizing a filling operation.

Background

A window frame is generally formed by extruding aluminum and has a groove around its outer periphery, and when the window frame is coupled to a wall, the groove faces the wall to form a gap between the window frame and the wall. In order to prevent water from penetrating into the groove from the vicinity of the window frame, a hole is usually drilled in the peripheral wall adjacent to the window frame, and a potting agent is filled into the hole to fill the groove, thereby achieving the waterproof effect.

Because the pouring agent cannot be directly seen after being poured into the wall, whether the pouring agent really flows to the vicinity of the window frame and whether the pouring agent is uniformly distributed is difficult to know, the control is carried out by the pouring amount of the pouring agent, if the pouring agent is poured too much, the excessive pouring agent extrudes the window frame after being expanded due to the expansion characteristic of the pouring agent, and if the pouring agent is poured too little, the effect of filling gaps and leakage repairing cannot be achieved. At present, no quantitative standard process can be referred to during the pouring operation, so that the constructors mostly judge whether the amount of the pouring agent is enough by experience and feeling, the construction result is greatly influenced by human factors, and the stability of the quality cannot be maintained.

Detailed Description

The invention is described in detail below with reference to the following figures and examples:

referring to fig. 1, 2, and 3, an embodiment of the method for repairing a leak of a window frame 1 according to the present invention is applied to a window frame 1 installed on a wall 2. The window frame 1 surrounds a groove 11 facing the wall 2, and includes a lower frame edge 12 disposed on the wall 2, two side frame edges 13 disposed at left and right ends of the lower frame edge 12 at an interval, and an upper frame edge 14 connected above the side frame edges 13. The groove 11 is defined by the lower frame 12, the side frame 13, and the upper frame 14, and the wall 2 is not completely attached to the window frame 1.

Referring to fig. 1, 4 and 5, the leakage repairing method includes an opening step 31, a venting step 32, a sealing step 33, and a filling step 34. In the step 31 of forming the hole, a plurality of pouring holes 41 are drilled in the wall 2 near the outer sides of the lower rim 12 and the side rim 13, and then a plurality of ventilation holes 42 communicating with the groove 11 are drilled in the lower rim 12 and the upper rim 14, which is to be noted that the ventilation holes 42 formed in the lower rim 12 and the upper rim 14 are located at the top of the groove 11, that is, at the relatively highest positions of the lower rim 12 and the upper rim 14.

In the ventilating step 32, gas is input through the filling hole 41, and it is confirmed whether the gas will be discharged through the ventilation hole 42, that is, whether the filling hole 41, the groove 11, and the ventilation hole 42 are communicated with each other. It should be noted that, although the pouring hole 41 is formed in the wall 2, there are gaps inside the wall 2, so that air can flow into the empty groove 11 through the gaps and further out through the air holes 42. Referring to fig. 1, 6 and 7, after it is confirmed that the gas is output from the ventilation holes 42, the plurality of ventilation pipes 43 are respectively inserted into the ventilation holes 42.

In the sealing step 33, a sealant is applied to the joint between the window frame 1 and the wall 2, and the side facing the outside needs to have high moisture resistance, so that silicone (silicone) is applied, while the side facing the inside needs to have low moisture resistance, so that AB (AB) is applied.

Referring to fig. 1, 6 and 8, in the pouring step 34, a pouring hole 41 of the wall 2 adjacent to the lower rim 12 is first poured, and a pouring agent enters the groove 11 through a gap of the wall 2, and flows out of the ventilation tube 43 after being stacked to a sufficient height to fill the groove 11. Then, the pouring holes 41 on the wall 2 adjacent to the side frame 13 are alternately poured, that is, the pouring holes 41 on the wall 2 adjacent to the two side frames 13 are alternately poured left and right, the pouring agent flows into the grooves 11 on the sides and accumulates upward, when the grooves 11 on the sides are filled, the continuously poured pouring agent starts to fill the grooves 11 on the top (i.e., the grooves 11 on the upper frame 14), and at this time, the pouring agent accumulates downward to fill the grooves 11 and gradually approaches the air holes 42 on the upper frame 14, and when the pouring agent overflows from the air permeable pipes 43, it indicates that all parts of the grooves 11 are filled with the pouring agent, so that a constructor can confirm whether to stop pouring the pouring agent by visually observing the air permeable pipes 43. After the construction is completed, the air permeable tube 43 is removed as shown in fig. 8, and the filling hole 41 and the air permeable hole 42 are filled. Since the opening of the gas permeable tube 43 is generally directed downward, a container may be provided below the gas permeable tube 43 to contain the pouring agent flowing out. In addition, since the wall 2 near the upper rim 14 is located above the upper rim 14 and the corresponding air holes 42, which is not favorable for pouring, when the pouring holes 41 need to be opened near the upper rim 14, it is considered that the pouring holes 41 are opened at the bottom end of the upper rim 14 as shown in fig. 6, so as to be favorable for pouring and meet different construction requirements.

It should be noted that, the perfusion agent used in this embodiment is a PU900 two-fluid perfusion agent, which is formed by mixing two types of perfusion agents, when the PU900 two-fluid perfusion agent is mixed, not only viscosity is generated, but also a little heat energy is generated, and in addition, the window frame 1 is an aluminum extrusion piece and is easy to transfer temperature, so that the heat energy of the perfusion agent in the groove 11 is transferred to the surface of the corresponding position of the window frame 1, and a constructor can touch the window frame 1 with a hand and feel the temperature thereof to confirm whether the perfusion agent is filled to the target position again. In addition to emitting heat, PU900 hardens after mixing, making the tapping sound thicker, allowing the operator to confirm whether the potting agent is filled by tapping the window frame 1. In addition, the PU900 has the characteristic that the new glue just injected can be combined with the old glue injected into a whole, so that the PU900 does not need to pay attention to whether the new glue and the old glue can be adhered or not, and the PU900 cannot shrink after being hardened, thereby reducing the generation of errors.

Through the opening positions of the pouring holes 41 and the air holes 42, the pouring agent can be ensured to flow out of the air holes 42 after the grooves 11 are filled with the pouring agent, so that a constructor can confirm whether the amount of the pouring agent is enough or not in a visual mode, the pouring operation has a set of quantifiable standard flow, and the pouring agent is injected to achieve the effects of preventing leakage and strengthening the structure. In addition, besides a visual mode, a constructor can also check whether the perfusion agent is injected into the target position through touch and hearing, and the perfusion accuracy is effectively improved.

In summary, the pouring holes 41 penetrating through the wall 2 and the air holes 42 communicating with the grooves 11 are formed, so that the effect of determining whether the pouring agent is enough can be achieved, interference of human factors can be reduced, standardization of a construction process is facilitated, and the purpose of the invention can be achieved.
