Description

Technical Field

[0001] This application relates to the field of prefabricated building technology, and in particular to a prefabricated wall panel window sill capping water-stopping device. Background Technology

[0002] A window sill coping is a reinforced concrete covering layer on the top of an exposed wall in a building. It is generally located at the top of the window sill, the bottom of the window, or the top of the parapet wall on the exterior wall. Window sill coping can reduce or avoid wall cracks caused by prestress concentration, and increase the stability of the window and the integrity and stability of the wall below the window sill.

[0003] In general, during building construction, in order to prevent rainwater from entering the room from the windowsill, a waterstop is integrally formed on the top of the windowsill. The waterstop is located on the edge of the top of the windowsill near the outside of the window, and the window frame is installed on the top of the windowsill inside the waterstop. The waterstop will play a role in stopping water.

[0004] However, during the implementation of the relevant technical solutions, at least the following technical problems were found: the water-stopping method of the water-stopping strip is simple, so the water-stopping effect is also relatively average. In the event of heavy rain, water will overflow the water-stopping strip and invade the inner side of the water-stopping strip, which will cause the window sill water-stopping to fail.

[0007] Furthermore, multiple sets of short plates are provided on the side wall of the horizontal plate facing the inside of the window. The multiple sets of short plates are distributed sequentially along the length of the horizontal plate, and there is a gap between adjacent sets of short plates. Each set of short plates includes an upper short plate and a lower short plate, both integrally formed with the side wall of the horizontal plate. The upper and lower short plates are horizontally arranged, with the upper short plate located above the lower short plate. The rubber strip has several strip holes for the short plates to pass through. The pressing component includes: a seat plate, formed at the bottom of the window frame, for abutting against the top surface of the concrete waterstop; and an elastic plate, formed on the bottom surface of the seat plate, for pressing down on the rubber strip between the side wall of the horizontal plate near the inside of the window and the groove wall of the mounting groove. The bottom of the elastic plate has a side hook, which is located below the lower short plate.

[0008] Furthermore, the upper edge of the upper short plate away from the horizontal plate has an upwardly angled hook, which is inclined towards the horizontal plate; the lower edge of the lower short plate away from the horizontal plate has a downwardly angled hook, which is inclined towards the horizontal plate; a retaining strip is provided between the horizontal plate near the inner wall of the window and the groove wall of the mounting groove, and the retaining strip is connected to multiple sets of the short plate groups; the retaining strip includes: a T-shaped strip, horizontally arranged, the web of the T-shaped strip being inserted into...

Detailed Implementation

[0022] This application discloses a prefabricated wall panel window sill capping water-stopping device. Through the connection between the clip 6 and the horizontal plate 2, the upper hook 62 and the lower hook 63 on the clip 6 will squeeze the rubber strip 3 towards the side wall of the horizontal plate 2, making the rubber strip 3 more tightly adhere to the side wall of the horizontal plate 2. The side hook 421 at the bottom of the elastic plate 1 42 will hook the bottom seat plate 41 of the window frame with the clip 6, improving the sealing between the window frame and the concrete waterstop 1. The elastic plate 2 43 will squeeze the part of the rubber strip 3 that abuts against the side wall of the assembly groove 11 near the inside of the window, making the rubber strip 3 more tightly adhere to the side wall of the assembly groove 11 near the inside of the window. The inclined water-draining plate 5 can drain the water dripping on the inclined water-draining plate 5 to the outside of the window. This solves the technical problem that the water-stopping method of the waterstop on the window sill capping in the prior art is simple and the water-stopping effect is generally poor. It realizes the assembly with the window frame to form a water-stopping device, strengthens the sealing between the waterstop and the window frame, and improves the water-stopping effect of the window sill capping.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] Reference Figure 1 , Figure 2 as well as Figure 3 The prefabricated wall panel window sill capping water-stopping device includes a concrete waterstop 1, a horizontal plate 2, a rubber strip 3, a pressure member 4, an inclined water-draining plate 5, and a retaining strip 6. The concrete waterstop 1 is formed on the top surface of the window sill capping 100. When the construction formwork for pouring the window sill capping 100 is erected, the construction formwork for the concrete waterstop 1 is also erected together. Thus, the concrete waterstop 1 and the window sill capping 100 are formed together. The two ends of the concrete waterstop 1 abut against the two side walls of the window sill 200. The concrete waterstop 1 is located on the edge of the window sill capping 100 near the outside of the window. The window frame is installed on the window sill capping 100 inside the waterstop. The pressure member 4 is part of the window frame and is integrally formed with the bottom of the window frame. Therefore, the design of the window frame needs to take the concrete waterstop 1 at the top of the window sill capping 100 of this application as a reference standard.

[0025] Continue to refer to Figure 3As shown, the top surface of the concrete waterstop 1 is provided with an assembly groove 11. The assembly groove 11 is a groove with a rectangular cross-section. The assembly groove 11 passes through both ends of the concrete waterstop 1. The assembly groove 11 is reserved before the concrete waterstop 1 is poured. Thus, the assembly groove 11 is formed at the same time after the concrete waterstop 1 is poured and formed. The assembly groove 11 occupies most of the volume of the concrete waterstop 1 near the window. The horizontal plate 2 is a rectangular plate located in the assembly groove 11. The length direction of the horizontal plate 2 is consistent with the length direction of the assembly groove 11. The horizontal plate 2 is placed upright in the assembly groove 11. The end faces of the horizontal plate 2 abut against the sides of the windowsill 200. The horizontal plate 2 is inserted into the bottom concrete of the assembly groove 11 before the concrete waterstop 1 is formed. There is a gap between the two side walls of the horizontal plate 2 in the length direction and the two side walls of the assembly groove 11 in the length direction. The gap between the side wall of the assembly groove 11 closer to the inside of the window and the horizontal plate 2 is greater than the gap between the side wall of the assembly groove 11 closer to the outside of the groove and the horizontal plate 2.

[0026] Reference Figure 3 and Figure 4 As shown, multiple sets of short boards 21 are provided on the side wall of the horizontal board 2 facing the window. The multiple sets of short boards 21 are distributed sequentially along the length direction of the horizontal board 2. There is a gap between adjacent sets of short boards 21, and the gap between the short board set 21 and the top surface of the horizontal board 2 is smaller than the gap between the short board set 21 and the bottom surface of the horizontal board 2. The short plate group 21 includes an upper short plate 211 and a lower short plate 212. Both the upper short plate 211 and the lower short plate 212 are strip plates, and their length direction is consistent with the length direction of the horizontal plate 2. Both the upper short plate 211 and the lower short plate 212 are integrally formed with the horizontal plate 2. The upper short plate 211 is located above the lower short plate 212. The upper short plate 211 and the lower short plate 212 are parallel to each other and have a gap between them. The upper edge of the upper short plate 211 away from the horizontal plate 2 has an upper oblique hook 2111, which is inclined towards the horizontal plate 2. The lower edge of the lower short plate 212 away from the horizontal plate 2 has a lower oblique hook 2121, which is inclined towards the horizontal plate 2.

[0027] Reference Figure 3 , Figure 4 as well as Figure 5As shown, the rubber strip 3 is placed in the assembly groove 11, and the rubber strip 3 is laid sequentially on one side wall of the assembly groove 11, the bottom surface of the assembly groove 11, one side wall of the horizontal plate 2, the top surface of the horizontal plate 2, the other side wall of the horizontal plate 2, the bottom surface of the assembly groove 11, and the other side wall of the assembly groove 11. The rubber strip 3 has several strip-shaped holes 31, the length direction of which is consistent with the length direction of the horizontal plate 2, and the several strip-shaped holes 31 are distributed sequentially along the length direction of the horizontal plate 2. The spacing between two adjacent strip-shaped holes 31 is equal, and the spacing is equal to the spacing between two adjacent sets of short plate groups 21. The several strip-shaped holes 31 on the rubber strip 3 are used for each short plate group 21 to pass through. When the rubber strip 3 passes through the short plate group 21, the upper oblique hook 2111 on the upper short plate 211 and the lower oblique hook 2121 on the lower short plate 212 can prevent the rubber strip 3 from detaching from the horizontal plate 2, thereby ensuring that the rubber strip 3 can play a long-term sealing and water-stopping role.

[0028] Continue to refer to Figure 3 , Figure 4 as well as Figure 5 As shown, the retaining strip 6 is located on the side of the horizontal plate 2 near the window. The retaining strip 6 is strip-shaped, and its length direction is consistent with the length direction of the horizontal plate 2. The retaining strip 6 is connected to multiple sets of short plate groups 21. The retaining strip 6 includes an integrally formed T-shaped strip 61, an upper hook 62, and a lower hook 63. The T-shaped strip 61 includes an integrally formed web 611 and a wing 612. The T-shaped strip 61 is horizontally arranged, and the web 611 of the T-shaped strip 61 is inserted between the upper short plate 211 and the lower short plate 212. The web 611 is interference-fitted with the upper short plate 211 and the lower short plate 212, so that when the T-shaped strip 61 is inserted into the short plate group 21, the retaining strip 6 can be tightly secured. Inserted on the horizontal plate 2, the wing plate 612 of the T-shaped strip 61 abuts against the end face of the upper short plate 211 and the lower short plate 212 away from the horizontal plate 2; the upper hook 62 is formed on the upper edge of the wing plate 612 of the T-shaped strip 61, and the upper hook 62 is used to hook with the upper oblique hook 2111 of the upper short plate 211; the lower hook 63 is formed on the lower edge of the wing plate 612 of the T-shaped strip 61, and the lower hook 63 is used to hook with the lower oblique hook 2121 of the lower short plate 212.

[0029] First, the rubber band 3 is passed through each short plate group 21. Then, the clamping strip 6 is connected to each short plate group 21 on the horizontal plate 2. When the upper hook 62 on the clamping strip 6 is hooked to the upper oblique hook 2111 of the upper short plate 211, and the lower hook 63 on the clamping strip 6 is hooked to the lower oblique hook 2121 of the lower short plate 212, the upper hook 62 and the lower hook 63 on the clamping strip 6 will press the rubber band 3 against the side wall of the horizontal plate 2, so that the rubber band 3 can fit more tightly against the side wall of the horizontal plate 2, and also ensure that the rubber band 3 will not detach from the horizontal plate 2.

[0030] Reference Figure 4 , Figure 5 as well as Figure 6As shown, the pressing component 4 is formed on the bottom surface of the window frame and is used to press against the rubber strip 3 between the side wall of the horizontal plate 2 near the inner side of the window and the groove wall of the mounting groove 11. The pressing component 4 includes an integrally formed seat plate 41, an elastic plate 42, and an elastic plate 43; the seat plate 41 is formed at the bottom of the window frame and is used to abut against the top surface of the concrete waterstop 1. When the window frame is installed on the window sill cap 100, the seat plate 41 at the bottom of the window frame will be in contact with the top surface of the concrete waterstop 1; the elastic plate 42 and the elastic plate 43 are parallel to each other and are integrally formed on the bottom surface of the seat plate 41. When the seat plate 41 is in contact with the top surface of the concrete waterstop 1, the elastic plate 42 and the elastic plate 43 are located on the horizontal plate 2 near the inner side of the window. Within the mounting groove 11 between one side wall and the groove wall of the mounting groove 11, the second elastic plate 43 is closer to the inside of the window. The first elastic plate 42 presses down on the rubber strip 3 between the horizontal plate 2 and the groove wall of the mounting groove 11. The bottom of the first elastic plate 42 has a side hook 421. When the first elastic plate 42 enters the mounting groove 11, the side hook 421 at the bottom of the first elastic plate 42 abuts against the bottom surface of the hook 63 under the retaining strip 6, thereby hooking the first elastic plate 42 and the retaining strip 6 together. Ultimately, the bottom seat plate 41 of the window frame hooks with the retaining strip 6, improving the sealing between the window frame and the concrete waterstop 1. The second elastic plate 43 is closer to the inside of the window, and after entering the mounting groove 11, the second elastic plate 43 will squeeze the part of the rubber strip 3 that abuts against the side wall of the mounting groove 11 near the inside of the window, making the rubber strip 3 fit more tightly against the side wall of the mounting groove 11 near the inside of the window. In addition, the seat plate 41 of the pressure member 4 has a hook 411 formed on the side facing outwards from the window. The side of the inclined water-guiding plate 5 near the inside of the window is connected to the hook 411. The side of the inclined water-guiding plate 5 near the outside of the window abuts against the side wall of the waterstop facing outwards from the window. The side of the inclined water-guiding plate 5 near the seat plate 41 is higher than the side near the outside of the window. Therefore, water dripping on the inclined water-guiding plate 5 can be guided outwards from the window.

[0031] The functional principle of this application can be explained through the following methods:

[0032] When the construction formwork for the pouring of the window sill cap 100 is erected, the construction formwork for the concrete waterstop 1 is also erected at the same time, and the assembly groove 11 is reserved before the concrete waterstop 1 is poured.

[0033] Before installing the window frame, place the rubber strip 3 in the mounting groove 11 and use the strip holes 31 on the rubber strip 3 to allow the rubber strip 3 to pass through each short plate group 21. Then connect the retaining strip 6 to each short plate group 21 on the horizontal plate 2. When the upper hook 62 on the retaining strip 6 hooks with the upper oblique hook 2111 of the upper short plate 211, and the lower hook 63 on the retaining strip 6 hooks with the lower oblique hook 2121 of the lower short plate 212, the upper hook 62 and the lower hook 63 on the retaining strip 6 will both squeeze the rubber strip 3 towards the side wall of the horizontal plate 2, so that the rubber strip 3 can fit more tightly against the side wall of the horizontal plate 2, and also ensure that the rubber strip 3 will not detach from the horizontal plate 2. After that, install the window frame on the window sill cap 100. The bottom plate 41 of the window frame will fit against the top surface of the concrete waterstop 1, and the side hook 421 at the bottom of the elastic plate 1 42 will abut against the retaining strip 6. On the bottom surface of the next hook 63, the elastic plate 42 and the clip 6 will be hooked together, and the bottom plate 41 of the window frame will be hooked together with the clip 6, which improves the sealing between the window frame and the concrete waterstop 1. The elastic plate 43 will squeeze the part of the rubber strip 3 that abuts against the side wall of the mounting groove 11 near the inside of the window, making the rubber strip 3 fit more tightly against the side wall of the mounting groove 11 near the inside of the window, further improving the sealing of the rubber strip 3. Finally, the side of the inclined water-guiding plate 5 near the inside of the window is hooked together with the side hook 411, and the side of the inclined water-guiding plate 5 near the outside of the window abuts against the side wall of the waterstop facing the outside of the window. Thus, the waterstop device of the prefabricated wall panel window sill capping 100 is installed, and there is waterstop between different parts, which strengthens the sealing between the waterstop and the window frame and improves the waterstop effect of the window sill capping 100.
