Description

Pre-buried leakage prevention method for window frame

The invention relates to a leakage prevention method, in particular to a pre-buried leakage prevention method for a window frame.

The general window frame is made of aluminum extrusion, and it surrounds a groove on the outer circumference. When the window frame is coupled to the wall, the groove will face the wall to create a gap between the window frame and the wall. In the event of heavy rain or when the weather is too humid, moisture can easily enter through these voids, causing water leakage and damaging the structure. In order to prevent moisture from penetrating into the groove near the window frame, it is often necessary to perform additional leak prevention works. In general, leak-proof works usually drill holes in the outer wall of the adjacent window frame, and fill the filling agent to fill the groove to achieve the waterproof effect. However, since the drilling holes need to be connected with the grooves covered by the wall and the window frame, the drilling project is quite a test of the construction personnel's technology, and the impure construction workers may take a lot of time or even drill out. Many unusable holes break the strength of the wall structure, which is not only time-consuming and laborious, but also needs to be refilled afterwards, resulting in low construction efficiency.

Accordingly, it is an object of the present invention to provide a leak proof method that is pre-embedded without the problem of drilling.

Therefore, the pre-buried leakage prevention method of the window frame of the present invention is applicable to a window frame disposed on a wall, and the window frame surrounds a groove facing the wall. The pre-buried leakage prevention method comprises a pre-buried step, an opening step, a venting step, a sealing step, and a pouring step.

In the pre-embedding step, at least one grouting tube having a plurality of open surfaces and a plurality of openings is embedded in the recess. In the opening step, a plurality of vent holes that communicate with the groove are formed in the window frame. In the venting step, gas is input from either end of the at least one grouting tube to confirm whether the gas is outputted from the vent holes, and a plurality of vent pipes that communicate with the vent holes are provided after confirmation. In the sealing step, the joint between the window frame and the wall is sealed. In the infusion step, the infusion agent is input to the at least one grouting tube until the infusion agent flows into the gas permeable tubes.

The utility model has the advantages that the grouting pipe having a plurality of openings is embedded in the groove when the window frame is installed in advance, and the subsequent step of the leakproof construction is not required in the subsequent step. The filling hole is opened in the body, and only the at least one grouting pipe is required for infusion, so that various problems caused by improper drilling on the wall can be avoided.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to FIG. 1, FIG. 2, and FIG. 3, a first embodiment of the pre-buried leakage prevention method of the window frame 11 of the present invention is applicable to a window frame 11 disposed on a wall 12. The sash 11 surrounds a groove 111 facing the wall 12, and includes a lower frame 112, two side frames 113 spaced apart from each other at the left and right ends of the lower frame 112, and a side connecting the sides The upper frame 114 of the frame 113.

Referring to FIG. 1, FIG. 4, and FIG. 5, the pre-buried leakage prevention method includes a pre-buried step 21, an opening step 22, a ventilation step 23, a sealing step 24, and a filling step 25. In the pre-embedding step 21, the grouting tubes 3 having the plurality of openings 30 on the three surfaces are respectively embedded in the recesses 111 corresponding to the lower frame 112 and the side frames 113 as shown in FIG. . It should be specially noted that the pre-embedding step 21 is usually performed when the window frame 11 is to be mounted on the wall 12 to achieve pre-installation effect. Both ends of each grouting pipe 3 pass through the wall 12 or the sash 11 and are shielded or sealed by other objects (not shown).

Referring to FIGS. 1 and 7, in the opening step 22, a plurality of vent holes 41 are formed at the relatively highest positions of the lower frame 112 and the side frames 113. Referring to Figures 1, 8, and 9, in the venting step 23, gas is input to either end of each of the grouting tubes 3, and it is confirmed whether the gas will be vented by the venting holes 41, that is, the same is confirmed. Whether the slurry pipe 3, the groove 111 and the vent holes 41 are in communication. After the ventilating is confirmed, it is convenient to provide the venting pipes 42 which are in communication with each other on the vent holes 41. In the sealing step 24, the sealant is applied at the joint between the window frame 11 and the wall 12, and the side facing the outside needs a high moisture resistance, so that a silicone resin is applied. The side facing the room is low in moisture, so the AB glue can be applied.

In the infusion step 25, the grouting pipe 3 corresponding to the lower frame 112 is first poured, and the infusion agent is simultaneously injected from the opening of the opposite ends of the grouting pipe 3, and the infusion agent is injected into the concave by the grouting pipe 3. The grooves 111 are discharged from the venting tubes 42 on the lower frame 112 after being stacked to a sufficient height. When the constructor visually sees that the boring agent flows into the venting tube 42 as described above, the pouring operation can be stopped. Then, the remaining two grouting tubes 3 corresponding to the side frames 113 are alternately infused, and similarly, each grouting tube 3 is simultaneously filled with perfusion agent at both ends of the grouting tube 3 during perfusion. The agent will enter the groove 111 from the grouting tubes 3, and continue to fill the groove 111 by both sides. After filling the grooves 111 on both sides, the filling portion 111 is filled. After the filling agent fills all the grooves 111, it will overflow from the vent pipes 42 located at the highest point of the side frames 113. When the constructor visually sees the infusion agent flowing into the venting pipe 42 as described above, The perfusion can be stopped and the perfusion action is completed. The venting tubes 42 can be removed after construction is completed and the venting holes 41 can be filled. The openings of the venting tubes 42 are generally oriented downwardly so that a container can be placed beneath the venting tubes 42 to accommodate the effluent perfusion.

It should be specially noted that the infusion agent used in the first embodiment may be a PU900 two-liquid type infusion agent, which is obtained by mixing two types of infusion agents, and when the PU900 two-liquid type infusion agent is mixed, not only It will produce viscousness and also generate some heat energy. The sash 11 is easy to transfer temperature due to the aluminum extrusion, so the thermal energy of the infusion agent in the groove 111 is transmitted to the surface corresponding to the sash 11 Therefore, the constructor can touch the window frame 11 by hand and feel the temperature to reconfirm whether the potting agent has filled to the target position. In addition to the heat generated, the PU900 will harden after mixing and thicken the knocking sound, allowing the constructor to confirm whether the infusion is filled by tapping the window frame 11. In addition, the PU900 also has the characteristics that the newly injected new glue can be combined with the injected old glue, so there is no need to pay attention to whether the new and old glues can be bonded together, and the PU900 will not shrink after hardening, which can reduce the error. produce. In addition to PU900 two-liquid infusion, it can also be changed to epoxy resin, hydrophilic foaming agent, resin mortar, or non-shrinking pure resin infusion agent.

When the sash 11 is installed, the grouting pipes 3 are preliminarily embedded in the recesses 111, so that the constructor does not need to drill holes in the wall 12 when performing the leakage prevention process, but only The opening step 22 to the infusion step 25 of the first embodiment can not only prevent the constructor from drilling through the porous hole and the costly process, but also avoid the structure of the wall 12 due to excessive drilling. Damaged situation. In addition, the construction personnel can select different sizes of the grouting pipe 3 corresponding to the grooves 111 of different sizes, and the configuration is simple and modular.

Referring to FIG. 1 and FIG. 10, a second embodiment of the pre-buried leakage prevention method of the window frame 11 of the present invention is substantially the same as the first embodiment, except that each grouting pipe 3 includes a buried pipe. a filling section 31 in the groove 111 (see FIG. 9) and opening the opening 30, a first observation section 32 connecting one end of the filling section 31, and a connecting end of the other end of the filling section 31 Second observation section 33. The first observation section 32 and the second observation section 33 are made of a transparent material, and respectively define a first injection port 321 that communicates with the openings 30, and a communication opening of the openings 30 and the first The second injection port 331 of the inlet 321 is injected.

In the infusion step 25, the infusion agent is first input from the first injection port 321 of the first observation section 32 until the infusion agent flows into the corresponding ventilation tube 42 and the infusion agent is visually observed to flow into the second portion. The perfusion was stopped after the observation section 33. The infusion is then input to the second injection port 331 of the second observation section 33 until the perfusion agent flows into the venting tubes 42 again, and the perfusion is visually observed to stop the perfusion after flowing into the first observation section 32.

In summary, the present invention pre-embeds the grouting pipes 3 when the sash 11 is installed, so that the constructor does not need to drill holes in the wall 12, thereby avoiding the influence of human factors, so The object of the invention is achieved.
