Description

Technical Field

[0001] The present invention belongs to the technical field of door and window installation, relates to an installation technology for ensuring the sealing performance of doors and windows, and particularly relates to an inner glass strip installation tool and an installation method. Background Art

[0002] Doors and windows are indispensable home decoration items in people's lives. The quality of doors and windows is closely related to the comfortable experience of people's home life. And for door and window products, it is "three parts product, seven parts installation", and door and window installation has a great impact on the quality of doors and windows. Doors and windows can be roughly classified according to their materials into: wooden doors and windows, steel doors and windows, plastic-steel doors and windows, aluminum alloy doors and windows, glass fiber reinforced plastic doors and windows, stainless steel doors and windows. With the continuous improvement of people's living standards, the types of doors and windows and their derivative products are increasing continuously, and the grades are gradually rising. For example, heat-insulating broken bridge aluminum doors and windows, aluminum-wood composite doors and windows, solid wood doors and windows, sun rooms, glass curtain walls, etc. Doors and windows can be classified according to their performance into: sound-insulating doors and windows, heat-insulating doors and windows, fire-proof doors and windows, airtight doors and windows. When many homeowners select and purchase indoor door and window products, they often only focus on the appearance and quality of the doors and windows, but rarely pay attention to the importance of door and window installation. If the doors and windows are not installed well, it will seriously affect the performance of the doors and windows such as use, heat preservation, airtightness, water tightness, and sound insulation, and even affect the use safety of the doors and windows in certain situations.

[0003] For door and window installation, the installation of door and window glass is particularly important. The cooperation between the glass and the window frame or door frame, and the installation tools or methods are directly related to the sound insulation performance, heat preservation performance, airtight performance, water tight performance, etc. of the doors and windows. When actually installing doors and windows, waterproof treatment is usually done on the outer side of the glass. During installation, multiple drainage holes are reserved at the bottom of the outer side of the doors and windows. At this time, the sealing between the inner glass of the doors and windows and the sash frame is very important. The sealing of the doors and windows is achieved by the compression between the inner glass strip (the inner glass strip is a sealing strip used for installing the inner side of the doors and windows) and the glass and the profile respectively. The quality of the installation of the inner glass strip directly determines the sealing effect of the entire doors and windows, and the sealing effect of the doors and windows directly affects the sound insulation performance, heat preservation performance, airtight performance, and water tight performance of the doors and windows. Therefore, the installation of the inner glass strip is particularly important in door and window installation.

[0004] At present, most use inner glass strips to achieve the sealing between the inner side of the glass and the sash frame. By using relatively thin inner glass strips, the strips are prone to deformation, and the airtightness maintenance effect after use is relatively poor. In order to ensure the airtight timeliness of door and window installation, generally, inner glass strips with a larger thickness are used. However, there are some problems in the installation of thick inner glass strips:

[0005] 1. When installing, it is necessary to manually press the inner glass strip. The manual pressing force is poor in consistency, and it may occur that some positions are not pressed in place, and the overall installation quality of the strip is relatively poor;

[0006] 2. Point-by-point pressing has a large workload, low efficiency, requires a great deal of force, and in actual work, workers are prone to slack off. There is a lack of quality inspection standards, resulting in poor performance of the installed doors and windows.

[0007] 3. The treatment of the rubber strip joints lacks standardization, and no shrinkage allowance is reserved. Due to the influence of temperature changes, gaps may appear at the joints, resulting in the sealing failure of the doors and windows and affecting the core performances such as the thermal insulation performance, airtight performance, and watertight performance of the doors and windows.

[0055] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention

[0056] Please refer to Figures 1 - 8 as shown, the specific embodiments provided by the present invention are as follows

[0057] Embodiment 1

[0058] An installation method for an inner glass strip, characterized by comprising the following steps

[0059] S1: Smoothly cut the sealing strip to obtain a first joint, and determine the installation position of the first joint

[0060] S2: Insert the rubber spatula into the installation seam on the adjacent side of the installation position, roll the first joint into the installation seam of the installation position with the rubber wheel, and install the sealing strip in a clockwise or counterclockwise direction;

[0061] S3: Make a mark A on the sealing strip, make a notch at the mark A, roll the part with the notch into the installation seam at the corner with the rubber wheel and the rubber spatula, so that the length of the sealing strip between the mark A and the first joint is B more than the actual length of the fan frame to be sealed. Roll the sealing strip with both ends fixed into the installation seam with the rubber wheel;

[0062] S4: Transfer the rubber spatula to the installation seam on the adjacent side, make a mark B on the sealing strip, make a notch at the mark B, roll the part with the notch into the installation seam at the corner with the rubber wheel and the rubber spatula, so that the length of the sealing strip between the mark B and the sealing strip at the previous corner is B more than the actual length of the fan frame to be sealed. Roll the sealing strip with both ends fixed into the installation seam with the rubber wheel;

[0063] S5: Repeat S4 until the installation seam on the last side of the fan frame to be sealed. Make a cutting mark on the sealing strip, and cut it flat at the cutting mark to obtain the second joint, so that the length of the second joint and the sealing strip at the previous corner is F more than the actual length of the fan frame to be sealed. Bond the first joint and the second joint to form the interface of the sealing strip. Roll the interface of the sealing strip into the installation seam of the installation position with the rubber wheel, and roll the sealing strip with both ends fixed into the installation seam with the rubber wheel;

[0064] Among them, making the notch is to cut 5 - 7 notches, and the interval between each notch is 3mm - 5mm.

[0065] In order to achieve the effect of airtightness on the inner side of the glass, the sealing strip has a certain thickness. The manual pressing force is not consistent, and some positions may not be pressed in place, resulting in poor overall installation quality of the rubber strip. Moreover, the workload of pressing point by point is large, the efficiency is low, and the required pressing force is also large. In actual work, workers are prone to being lazy. No shrinkage allowance is left at the joint. Due to the influence of temperature change, gaps appear at the joint, resulting in the destruction of the sound bridge and heat bridge of the sound insulation and heat insulation doors and windows, affecting the core performance of the doors and windows. Even if the installation quality meets the requirements during the acceptance after installation, but after 1 - 2 years, the rubber strip inside the glass shrinks severely, resulting in the sealing failure at the corner or joint, a large number of cracks appear, and a large amount of dust accumulates in the cracks, greatly reducing the airtightness and sound insulation performance, seriously affecting the customer experience.

[0066] In this embodiment, as Figure 1As shown, a method for installing an inner-glass rubber strip is provided, which is characterized by the following steps: S1: Cut the sealing strip flatly to obtain a first joint, and determine the installation position of the first joint; S2: Insert a rubber spatula into the installation seam on the adjacent side of the installation position, and roll the first joint into the installation seam at the installation position with a rubber wheel, and install the sealing strip in a clockwise or counterclockwise direction; S3: Make a mark A on the sealing strip, make a notch at the mark A, and roll the part with the notch into the installation seam at the corner with a rubber wheel and a rubber spatula, so that the length of the sealing strip between the mark A and the first joint is B more than the actual length of the fan frame to be sealed. Roll the sealing strip with both ends fixed into the installation seam with a rubber wheel; S4: Transfer the rubber spatula to the installation seam on the adjacent side, make a mark B on the sealing strip, make a notch at the mark B, and roll the part with the notch into the installation seam at the corner with a rubber wheel and a rubber spatula, so that the length of the sealing strip between the mark B and the sealing strip at the previous corner is B more than the actual length of the fan frame to be sealed. Roll the sealing strip with both ends fixed into the installation seam with a rubber wheel; S5: Repeat S4 until the installation seam on the last side of the fan frame to be sealed. Make a cut-off mark on the sealing strip, and cut it flatly at the cut-off mark to obtain a second joint, so that the length of the second joint and the sealing strip at the previous corner is F more than the actual length of the fan frame to be sealed. The first joint and the second joint are bonded to form an interface of the sealing strip. Roll the interface of the sealing strip into the installation seam at the installation position with a rubber wheel, and roll the sealing strip with both ends fixed into the installation seam with a rubber wheel; wherein, making the notch is to cut 5-7 notches, and the interval between each notch is 3mm-5mm.

[0067] When the present invention makes an inner-glass seal for a fan glass, there is only 1 joint for the sealant. Reducing the number of joints can reduce the points of airtight failure. Moreover, the present invention uses a rubber wheel and a rubber spatula in cooperation to install the sealing strip. On the one hand, inserting the rubber spatula into the installation seam can increase the installation gap, so that the staff can press the sealing strip into the installation seam with less force. For the same workload requirement, it takes 2 hours to press and install the inner-glass rubber strip manually point by point, and the staff's fingers are sore and tired after pressing. The installation of the inner-glass rubber strip of the present invention only takes 0.5 hours. The installation method of the present invention is more labor-saving and greatly saves the installation time. On the other hand, the present invention reserves a margin on each installation side, which can largely overcome the problem of gaps at the corners or joints caused by the expansion and contraction due to temperature difference.

[0068] The present invention makes notches on the sealing strip at the corner of the installation joint. The notches are made by shearing 5 - 7 notches, with each notch spaced 3 mm - 5 mm apart. A rubber wheel and a rubber spatula are used to roll the part with notches into the installation joint at the corner. On the one hand, more allowance is reserved at the notch, which can overcome the expansion and contraction caused by temperature difference. When the temperature difference changes greatly, shearing 5 - 7 notches can ensure that there is always a notch at the corner. At this time, the sealing strip at the corner can continue to maintain a 90 - degree perpendicularity and is not easily pulled and deformed. On the other hand, the notch making has the function of positioning the installation of the sealing strip, ensuring the long - term effectiveness of the airtightness at the corner. On the third hand, it is possible to maintain the aesthetics of a 90 - degree angle at the corner without cutting the sealing strip.

[0069] Example 2:

[0070] The value range of B is 2% - 4%;

[0071] The value range of F is 5 mm - 10 mm.

[0072] In S1,

[0073] The installation position of the sealing strip is at the middle position of the top edge of the installation joint. After the glass is installed, the distance from the top edge of the installation joint to the ground is greater than the distance from the non - top edge of the installation joint to the ground.

[0074] The installation position of the sealing strip is at the middle position of the top edge of the installation joint. After the glass is installed, the distance from the top edge of the installation joint to the ground is greater than the distance from the non - top edge of the installation joint to the ground.

[0075] If the allowance reserved on each frame is too small, the temperature difference will easily cause the corner and the joint to be stretched and deformed, and cracks will appear. On the one hand, the airtightness and sound insulation performance become poor. On the other hand, the cracked gaps will accumulate dust, bacteria, etc. over a long time, which not only affects the aesthetics but also the user experience.

[0076] In this embodiment, the value range of B is 2% - 4%; the value range of F is 5 mm - 10 mm. After 1 - 3 years of installing the doors and windows, the airtight performance at the corner and the joint differs from the airtight performance at the time of installation by within 5%, which can effectively ensure the long - term performance of the doors and windows.

[0077] Due to severe shrinkage at the corner of the installation joint, the joint of the sealing strip cannot be installed at the corner. The installation position of the sealing strip is at the middle position of the top edge of the installation joint. After the glass is installed, the distance from the top edge of the installation joint to the ground is greater than the distance from the non - top edge of the installation joint to the ground. The present invention can not only avoid excessive expansion and contraction at the corner and the appearance of cracks, but also improve the aesthetics of the installation.

[0078] Example 3:

[0079] When cutting the notch, the airtight cavity of the sealing strip itself shall not be cut.

[0080] In this embodiment, as Figure 2 shown, one side of the glass 1 is in sealed contact with the outer glass strip 101, and the outer glass strip 101 is located on the outer side of the window. The other side of the glass 1 is in sealed contact with the sealing strip 102, and the sealing strip is located in the installation gap between the glass 1 and the pressing strip 103. Since the sealing strip 102 has a sealing cavity 1021, when the glass and the pressing strip squeeze the sealing strip, the sealing cavity will have a reaction force on the outside when being squeezed, so that the pressure between the sealing strip and the glass and the pressing strip is greater, achieving a tighter sealing effect. When cutting the shear notch, the airtight cavity of the sealing strip itself shall not be cut, which can increase the effective service life of the sealing strip.

[0081] Example 4:

[0082] When rolling the sealing strip fixed at both ends into the installation gap with a rubber wheel,

[0083] Roll the N-equal division points of the sealing strip into the N-equal division positions of the to-be-installed gap with a rubber wheel. Starting from the N-equal division positions respectively, roll in two directions away from the N-equal division positions until the whole sealing strip is rolled into the installation gap;

[0084] wherein, N is an integer greater than 2.

[0085] When rolling the sealing strip fixed at both ends into the installation gap with a rubber wheel,

[0086] Press the midpoint of the sealing strip into the midpoint position of the to-be-installed gap with a rubber wheel. Starting from the midpoint position as the first starting point, roll in two directions away from the first starting point until the whole sealing strip is pressed into the installation gap.

[0087] Since the sealing strip is made of flexible material and has stretchability, when the rubber wheel rolls the sealant, in addition to the force of pressing the sealant into the installation gap, due to the rubber wheel rolling on the sealing strip, the rubber wheel has a lateral acting force on the sealing strip, causing the sealing strip to be stretched. When rolling the sealing strip from the front end of the to-be-installed side to the rear end, there will be a relatively long sealing strip at the rear end that cannot be normally pressed into the installation gap, and the sealing strip at the front end is in a stretched state, and the temperature difference causes it to expand and contract, seriously affecting the airtight performance at the front end.

[0088] In this embodiment, when using a rubber wheel to roll a sealing strip with both ends fixed into the installation seam, the N-equal division points of the sealing strip are rolled into the N-equal division positions of the to-be-installed seam by the rubber wheel, and starting from the N-equal division positions respectively, roll in two directions away from the N-equal division positions until the entire sealing strip is rolled into the installation seam; initially position the sealing strip by pressing the N-equal division points into the N-equal division positions of the to-be-installed seam through a wire, and then use a roller to roll and press the sealing strip in two directions away from the N-equal division points. The present invention can ensure that the surplus of the sealing strip is evenly distributed in various places of the to-be-installed edge, avoiding the problems of the surplus of the sealing strip accumulating in one place and insufficient surplus in many places, effectively improving the airtight performance of the installation of the inner glass strip, and increasing the duration of maintaining the airtight effect.

[0089] Embodiment 5:

[0090] When using a rubber wheel to roll a sealing strip with both ends fixed into the installation seam,

[0091] Press the equal division points of the sealing strip into the equal division positions of the to-be-installed seam by the rubber wheel. The distance between adjacent equal division positions is 20 cm - 30 cm. Starting from the equal division positions respectively, roll in two directions away from the equal division positions until the entire sealing strip is pressed into the installation seam.

[0092] In this embodiment, due to the large expansion and contraction amount at the corner caused by the temperature difference, the present invention starts from the equal division positions respectively and rolls in two directions away from the equal division positions until the entire sealing strip is pressed into the installation seam. More surplus can be rolled to the corner, which can relieve the situation of cracks appearing due to expansion and contraction at the corner.

[0093] Embodiment 6:

[0094] When using a rubber wheel to roll a sealing strip with both ends fixed into the installation seam,

[0095] There is a primary rolling and a secondary rolling. First, perform a primary rolling on the sealing strip, and then perform a secondary rolling on the sealing strip;

[0096] Among them, for the primary rolling, roll the rubber wheel with a force of 30%F' - 50%F', and for the secondary rolling, roll the rubber wheel with a force of 60%F' - 80%F', where F' is the average force required to roll the entire sealing strip into the installation seam.

[0097] When pressing the sealing strip into the installation seam at one time, first, a relatively large force is required. Secondly, a part of the sealing strip is located in the card slot of the wire pressing, and the other part is outside the card slot. Since the sealing strip is larger than the installation seam, at this time, the part of the sealing strip stuck by the wire pressing is in a stretched state. When rolling the sealing strip to the back, a lot of surplus will accumulate in the sealing strip, resulting in a serious uneven distribution of the surplus on the to-be-installed edge.

[0098] In this embodiment, when the sealing strip fixed at both ends is rolled into the installation seam by a rubber wheel, there is a primary rolling and a secondary rolling. First, the sealing strip is subjected to primary rolling, and then the sealing strip is subjected to secondary rolling. Among them, the primary rolling is carried out with a force of 30%F'-50%F' on the rubber wheel, and the secondary rolling is carried out with a force of 60%F'-80%F' on the rubber wheel, where F' is the average force required to roll the entire sealing strip into the installation seam. Through the primary rolling, part of the sealing strip is pressed into the installation seam, and the surplus of the sealing strip is first evenly distributed into the installation seam, and then the secondary rolling is carried out. The secondary rolling can greatly reduce the stretching amount of the sealing strip at the junction, so that the surplus of the sealing strip on the edge to be installed is evenly distributed on the edge to be installed, achieving a more stable airtightness.

The employee holds the handle and applies force to the handle to push the roller to roll, avoiding the inconsistency of pressing caused by directly pressing the sealing strip with the hand, and also greatly saving the time of installing the sealing strip.

[0108] A schematic diagram of a rubber spatula is shown in FIG. Figure 3 As shown, the working part of the glue spatula is in an arc wave shape, which is more convenient for the staff to pinch and hold. The protrusion of the first extrusion surface is in a triangular hook shape. The side of the triangular hook that is inserted into the installation seam has a large inclination angle, which is more convenient for insertion. The side of the triangular hook that is pulled out of the installation seam has a vertical inclination angle, so that the glue spatula can be firmly engaged after being inserted into the installation seam.

[0109] In one embodiment, the roller of the rubber wheel is made of nylon material, which is not easy to deform the rubber strip.

[0110] Embodiment 8:

[0111] The first extrusion surface is provided with a scale, and the scale can display the distance value between the scale position and the first extrusion surface.

[0112] During the actual installation process, if the employees lack practical operating experience and use excessive force to press the working part of the spatula into the installation seam, it is very easy to damage the glass and the pressing line. The damaged glass can also easily endanger the personal safety of the construction workers.

[0113] In this embodiment, if Figure 4 As shown, the first extrusion surface has a scale 23, and the scale 23 can display the distance value between the scale position and the first extrusion surface. When inserting the spatula into the installation seam, the construction personnel can read the scale value of the first surface to judge the depth of the spatula, so as to ensure that the inserted spatula will not damage the glass, and at the same time, the force of rolling the sealing strip into the installation seam can be reduced as much as possible, so as to ensure the effectiveness and safety of the installation.

[0114] Embodiment 9:

[0115] The roller has a pressing part and a non-pressing part. The pressing part can contact the sealing strip and is used to press the sealing strip. The non-pressing part is used to connect the pressing part and the connecting shaft. The maximum distance between the pressing part and the connecting shaft is 15 mm - 30 mm, and the thickness of the roller is 8 mm - 12 mm;

[0116] The cross-sectional graph passing through the connecting shaft has an outer arc segment and a connecting segment. The outer arc segment is the contour line of the cross-section of the pressing part, and the connecting segment is the contour line of the cross-section of the non-pressing part.

[0117] The pressing part of the roller is convex. The outer arc segment is an asymmetric graph with smooth connection. The outer arc segment has a large convex segment and a small convex segment. The radius of curvature of the large convex segment is smaller than that of the small convex segment, and the total length of the large convex segment is greater than that of the small convex segment.

[0118] When installing the inner glass sealing strip, due to different installers and different installation positions of the inner glass sealing strip, for floor-to-ceiling windows, the lowest installation edge is close to the ground, and the highest edge is above the head. For example, when the installer rolls the sealing strip close to the ground, due to the relative position relationship between the sealing strip and the person, the included angle range between the direction of the installer holding the handle and the glass is 30° - 45 degrees. If the height of the sealing strip to be rolled is at the chest height of the staff, the included angle range between the direction of the installer holding the handle and the glass is 45° - 60 degrees. Since the staff applies force to the roller through the handle, the direction of holding the handle causes a change in the application direction. Different application directions result in different contact points between the roller and the sealing strip, and the magnitude and direction of the force on the sealing strip are also different. In different directions, the staff needs to use different forces to press the sealing strip into the installation seam. When installing the sealing strip above the shoulder, the muscles of the staff are in a highly tense state. When installing the sealing strip near the ground, most of the gravity of the hand is also applied to the handle, and the muscles are in a relatively comfortable state. The rapid alternation of the tense and relaxed states of the muscles throughout the day can easily cause soreness and muscle strain in the arm.

[0119] In this embodiment, as Figures 5 - 8 shown, the roller 32 has a pressing part 3201 and a non-pressing part 3202. The pressing part can contact the sealing strip and is used to press the sealing strip 102. The non-pressing part is used to connect the pressing part and the connecting shaft. The maximum distance between the pressing part and the connecting shaft is 15 mm - 30 mm, and the thickness of the roller is 8 mm - 12 mm; The cross-sectional graph passing through the connecting shaft has an outer arc segment and a connecting segment. The outer arc segment is the contour line of the cross-section of the pressing part, and the connecting segment is the contour line of the cross-section of the non-pressing part. The pressing part of the roller is convex. The outer arc segment is an asymmetric graph with smooth connection. The outer arc segment has a large convex segment 322 and a small convex segment 321. The radius of curvature of the large convex segment is smaller than that of the small convex segment, and the total length of the large convex segment is greater than that of the small convex segment.

[0120] When using the rubber wheel, the roller 32 where the small convex segment 321 is located faces the side of the glass 1, and the roller 32 where the large convex segment 322 is located faces away from the side of the glass 1. When the angle between the handle and the glass is 20° - 60°, the contact point of the roller with the sealing strip remains basically unchanged, the force application points of the sealing strip are basically the same, and the magnitudes of the forces applied to the sealing strip are also basically the same. Workers can roll the sealing strip into the installation seam with basically the same force, and the muscles of the workers are in a stable and tense state, effectively reducing the state of muscle soreness after work.

[0121] Embodiment 10:

[0122] The angle between the extrusion part and the non-extrusion part is 5° - 15°.

[0123] When rolling the sealing strip, 60% - 80% of the force is required to press the sealing strip into the installation seam, 20% - 30% of the force is also required to press it towards the glass side, and a rolling force parallel to the length direction of the sealing strip is also required. In actual installation, due to different installation habits of workers, the installation force is not evenly distributed, resulting in unnecessary physical effort. Moreover, when rolling the sealing strip, due to the obstruction of the glass, the working space of the arm is very limited.

[0124] In this embodiment, as Figure 7 shown, the angle between the extrusion part and the non-extrusion part is 5° - 15°. During installation, the arm does not need to be closely attached to the glass, and a pressing force can still be applied to the sealing strip, enabling a larger pressing space for the arm.
