Description

Technical Field

[0001] The invention relates to a paving device, and more particularly to a paving device for indoor waterproof coiled materials of a house. Background Art

[0002] When decorating a house, waterproof membrane is usually laid on the ground under the floor. The construction environment inside the house is quite different from that outside, and the materials of the selected waterproof membrane are also different. Since the maintenance of the waterproof membrane inside the house is more troublesome, synthetic polymer waterproof membrane is usually selected. Due to the characteristics of the material, the surface of the synthetic polymer waterproof membrane is relatively smooth and easy to repel water, but the adhesion performance is poor. In order to ensure the tightness of the paste, the pasting method is adopted. In the prior art, glue is arranged in advance in the area where the waterproof membrane is laid to facilitate rapid laying construction. However, in actual use, it is found that due to the relatively closed indoor environment, the dust accumulates quickly, and the exposed surface of the glue is easily contaminated with dust and impurities, which makes it difficult for the glue to bond with the waterproof membrane. Therefore, a device for laying indoor waterproof membrane in a house is needed, which can lay glue and waterproof membrane at the same time.

[0003] In view of the above reasons, how to lay glue and waterproof membrane at the same time is exactly the problem considered in this application. Summary of the invention

[0004] Aiming at the deficiencies in the prior art, a device for laying indoor waterproofing coiled material in a house is provided, wherein the device can lay glue and waterproofing coiled material at the same time.

[0005] To achieve the above purpose, the following technical scheme is provided: a device for laying indoor waterproof coiled materials in a house, comprising a frame, a handle assembly, a power assembly, a leveling assembly, a storage assembly, a glue brushing assembly and a laying assembly, wherein the power assembly, the leveling assembly, the storage assembly, the glue brushing assembly and the laying assembly are all installed on the frame, the handle assembly is slidably connected to the frame, the leveling assembly is connected to the power assembly, and the glue brushing assembly and the laying assembly are both connected to the handle assembly;

[0006] When the power assembly is started, the leveling assembly is started;

[0007] When the handle assembly moves downward and the power assembly is started, the handle assembly is connected to the power assembly, and the storage assembly, the glue application assembly and the paving assembly are all started;

[0008] When the handle assembly moves upward, the handle assembly is separated from the power assembly, and the storage assembly, the glue application assembly and the paving assembly are all stopped.

[0009] In summary, the above technical solution has the following beneficial effects: indoor waterproofing membrane paving is a construction link with diversified options. Compared with the common outdoor waterproofing membrane paving, the indoor environment of the house is less affected by the environment, and the focus is usually on whether the environment itself meets the regulations. Therefore, the treatment of the base floor can be simplified, and the finished glue can be directly covered on the concrete base. There is no need to mix glue for the environmental base floor treatment, so a glue brushing component can be directly set for glue brushing;

[0010] Synthetic polymer waterproofing membrane is suitable for indoor waterproofing decoration, usually EPDM rubber membrane can be used. The waterproofing membrane may be wrinkled or warped due to extrusion or collision during transportation, which will greatly affect the waterproofing effect after paving. Therefore, a leveling component is set to pre-level the waterproofing membrane;

[0011] The surface of synthetic polymer waterproofing membrane is relatively smooth. In order to prevent the surface from being damaged, a cushion layer is usually set. This cushion layer is used to isolate the full-strength on both sides. However, it needs to be torn apart during the actual paving process, which increases the workload in disguise. Therefore, a storage component is set to roll up the cushion layer and drive the release of the waterproofing membrane;

[0012] In actual construction, waterproofing membranes are usually laid before pipes, while outdoor construction is usually done in completed areas, that is, waterproofing membranes are laid in advance in indoor construction and in the final stage of outdoor construction. Considering that there are often various debris in outdoor spaces that hinder large-area waterproofing, they need to be cut and spliced ​​to fit tightly, so it is not suitable to use an integrated paving device. On the contrary, indoor construction can use an integrated paving device to speed up construction efficiency, so the glue brushing components and paving components are concentrated on the rack;

[0013] The glue coating itself also has a certain waterproof function. The combination of waterproof membrane and glue coating can strengthen the sealing at corners, pipe roots, wall roots and other places. The waterproof membrane is repeatedly wrapped to cover a large area, taking into account continuity and crack resistance. In this case, the waterproof membrane only needs to be leveled before use, so the leveling component is connected to the power component, and the power component can directly drive the leveling component to start, while the glue brushing component and the paving component are both connected to the handle component. Only when the handle component is moved down can the power component drive the glue brushing component and the paving component to start, so that only the leveled waterproof membrane can be pulled out for use to prevent waste of glue;

[0014] In addition, in order to prevent the waterproofing membrane from overlapping due to negligence of the staff, the handle assembly is connected to the power assembly when and only when the handle assembly moves down and the power assembly is started, the glue brushing assembly and the paving assembly can be started. The release of the waterproofing membrane mainly depends on the storage assembly, and the leveling assembly does not have the function of driving the release of the waterproofing membrane. In this way, even if the staff let go due to negligence, the storage assembly will automatically stop running, thereby preventing the waterproofing membrane from overlapping due to negligence of the staff;

[0015] The present invention concentrates the glue applying component and the laying component on the frame, so that glue and waterproof coiled materials can be laid at the same time, and a storage component is provided to drive the release of the waterproof coiled materials, a leveling component is provided to pre-treat the waterproof ring, and a movable handle component is provided as a safety to improve the entire device.

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0029] Reference Figure 1-5 As shown, the indoor waterproof coiled material paving device for a house comprises a frame 1, a handle assembly 2, a power assembly 3, a leveling assembly 4, a storage assembly 5, a glue brushing assembly 6 and a paving assembly 7, wherein the power assembly 3, the leveling assembly 4, the storage assembly 5, the glue brushing assembly 6 and the paving assembly 7 are all installed on the frame 1, the handle assembly 2 is slidably connected to the frame 1, the leveling assembly 4 is connected to the power assembly 3, and the glue brushing assembly 6 and the paving assembly 7 are both connected to the handle assembly 2;

[0030] When the power assembly 3 is started, the leveling assembly 4 is started;

[0031] When the handle assembly 2 moves downward and the power assembly 3 is started, the handle assembly 2 is connected to the power assembly 3, and the storage assembly 5, the glue application assembly 6 and the paving assembly 7 are all started;

[0032] When the handle assembly 2 moves upward, the handle assembly 2 is separated from the power assembly 3, and the storage assembly 5, the glue application assembly 6 and the paving assembly 7 are all stopped.

[0033] The laying of indoor waterproofing membranes in residential buildings is a construction link with diversified options. Compared with the laying of common outdoor waterproofing membranes, the indoor environment of residential buildings is less affected by the environment, and the focus is usually on whether the environment itself meets the regulations. Therefore, the treatment of the base floor can be simplified, and the finished glue can be directly covered on the concrete base. There is no need to mix glue for the environmental base floor treatment, so the glue brushing component 6 can be directly set for brushing glue;

[0034] Synthetic polymer waterproofing membrane is suitable for indoor waterproofing decoration, and EPDM rubber membrane can usually be used. The waterproofing membrane may be wrinkled or warped due to extrusion or collision during transportation, which will greatly affect the waterproofing effect after paving. Therefore, a leveling component 4 is provided to pre-level the waterproofing membrane;

[0035] The surface of the synthetic polymer waterproofing membrane is relatively smooth. In order to prevent the surface from being damaged, a cushion layer is usually provided. This cushion layer is used to isolate the full talents on both sides. However, it needs to be torn apart during the actual paving process, which increases the workload in disguise. Therefore, a storage component 5 is provided to roll up the cushion layer and drive the release of the waterproofing membrane;

[0036] In actual construction, waterproofing coiled materials are usually laid before pipes, while outdoor construction is usually carried out in the area where construction is completed, that is, the laying of waterproofing coiled materials is pre-constructed in indoor construction and is the finishing construction in outdoor construction. Considering that there are often various debris in outdoor space that hinder large-area subsidies, it is necessary to cut and splice them tightly, so it is not suitable to use an integrated laying device. On the contrary, indoor construction can use an integrated laying device to speed up construction efficiency, so the glue brushing component 6 and the laying component 7 are concentrated on the frame 1;

[0037] The glue coating itself also has a certain waterproof function. The combination of waterproof coiled material and glue coating can strengthen the sealing at corners, pipe roots, wall roots and other places. The waterproof coiled material is repeatedly wrapped to cover a large area, taking into account continuity and crack resistance. In this case, the waterproof coiled material only needs to be leveled before use, so the leveling component 4 is connected to the power component 3, and the power component 3 can directly drive the leveling component 4 to start, and the glue brushing component 6 and the paving component 7 are both connected to the handle component 2. Only when the handle component 2 moves down can the power component 3 drive the glue brushing component 6 and the paving component 7 to start. In this way, only the leveled waterproof coiled material can be pulled out for use to prevent waste of glue;

[0038] In addition, in order to prevent the waterproofing roll from overlapping due to negligence of the staff, when and only when the handle assembly 2 moves down and the power assembly 3 is started, the handle assembly 2 is connected with the power assembly 3, and the glue brushing assembly 6 and the paving assembly 7 can be started, wherein the release of the waterproofing roll mainly depends on the storage assembly 5, and the leveling assembly 4 does not have the function of driving the release of the waterproofing roll. In this way, even if the staff is careless and lets go, the storage assembly 5 will automatically stop running, thereby preventing the waterproofing roll from overlapping due to negligence of the staff;

[0039] The present invention concentrates the glue-brushing assembly 6 and the laying assembly 7 on the frame 1, so as to lay glue and waterproof membrane at the same time, and provides a storage assembly 5 for driving the release of the waterproof membrane, a leveling assembly 4 for pre-processing the waterproof ring, and a movable handle 21 assembly as insurance to improve the entire device.

[0040] Further, the power assembly 3 includes a motor 31, a first transmission belt 32 and a first transmission wheel 33, the grip assembly 2 includes a handle 21, a first connecting rod 22, a second transmission wheel 23, a tensioning device 24 and a second transmission belt 25, the first transmission belt 32 is connected to the motor 31, and is used to drive the leveling assembly 4 to start, the first transmission wheel 33 is connected to the motor 31, the handle 21 is fixedly connected to the first connecting rod 22, the second transmission wheel 23 is rotatably connected to the first connecting rod 22, the second transmission belt 25 is connected to the second transmission wheel 23, and is used to drive the storage assembly 5, the glue brushing assembly 6 and the paving assembly 7 to start, the fixed end of the tensioning device 24 is fixedly connected to the frame 1, and the movable end of the tensioning device 24 is connected to the second transmission belt 25;

[0041] When the handle 21 moves downward, the first connecting rod 22 drives the second transmission wheel 23 to move downward, the second transmission wheel 23 engages with the first transmission wheel 33, and the storage assembly 5, the glue application assembly 6 and the paving assembly 7 are all started.

[0042] As the most basic power source, the motor 31 can be connected to multiple transmission mechanisms at the same time and can drive multiple transmission mechanisms to work synchronously. Therefore, the present invention provides relatively independent first transmission belts 32 and second transmission belts 25. When the motor 31 is started, the first transmission belt 32 and the second transmission belt 25 can be driven to work simultaneously. A first transmission wheel 33 and a second transmission wheel 23 are provided. The control effect is achieved by the engagement and separation of the first transmission wheel 33 and the second transmission wheel 23. During this period, the second transmission belt 25 will become loose due to the change in relative distance. Therefore, a tensioning device 24 is provided to maintain the taut state of the second transmission belt 25 to prevent the second transmission belt 25 from falling off.

[0043] Furthermore, the grip assembly 2 also includes a second connecting rod 26 and a first spring 27 . The second connecting rod 26 is fixedly connected to the handle 21 , and two ends of the first spring 27 are fixedly connected to the second connecting rod 26 and the frame 1 , respectively.

[0044] The first spring 27 is mainly used to drive the handle 21 to be at the highest point at all times, that is, the second transmission wheel 23 is always separated from the first transmission wheel 33, and in order to facilitate the installation of the entire device, the space in the frame 1 can be divided into multiple layers by partitions. For example, the first spring 27 and the second connecting rod 26 are arranged in the connecting layer, the components of the storage component 5, the glue brushing component 6 and the paving component 7 that play a paving-related role are arranged in the working layer, and the first transmission belt 32 and the second transmission belt 25 are arranged in the transmission layer.

[0045] Furthermore, the leveling assembly 4 includes a placing piece 41, a positioning shell 42 and a leveling roller 43. The placing piece 41 and the positioning shell 42 are both fixedly connected to the frame 1. The placing piece 41 is used to place the waterproof roll material. The leveling roller 43 is rotatably connected to the positioning shell 42. The leveling roller 43 is connected to the first transmission belt 32. The placing piece 41 is fixedly connected to one end of the frame 1 away from the handle assembly 2, and the positioning shell 42 is fixedly connected to the frame 1.

[0046] Furthermore, the leveling assembly 4 also includes a telescopic device 44, a first connector 45, a second connector 46 and a grinding roller 47. The first connector 45 is fixedly connected to the positioning shell 42, the second connector 46 is detachably connected to the grinding roller 47, the first connector 45 is detachably connected to the second connector 46, the telescopic end of the telescopic device 44 abuts against the second connector 46, and the grinding roller 47 is arranged above the leveling roller 43.

[0047] The placement member 41 is used to place the waterproofing coiled material. For safety reasons and to facilitate the placement of the waterproofing coiled material, the placement member 41 is fixedly connected to the end of the frame 1 away from the handle assembly 2 to avoid accidental start-up when placing the waterproofing coiled material.

[0048] The leveling function is mainly accomplished by the leveling roller 43. The leveling roller 43 can press the wrinkles and warps on the waterproofing membrane to flatten the uneven surface. Although there is a cushion layer as a buffer, the leveling roller 43 itself is set to rotate during operation to further reduce the friction loss on the waterproofing membrane in order to prevent any accidents.

[0049] In addition, in order to increase the degree of adhesion of the glue, a frosting roller 47 is provided. The side of the waterproof membrane that is not protected by the cushion layer is usually a glue bonding layer. When passing through the frosting roller 47, cuts of varying depths will be produced, thereby increasing the actual contact area with the glue. This requires increasing the friction between the frosting roller 47 and the waterproof membrane, so the frosting roller 47 cannot rotate. At the same time, the frosting roller 47 is also a consumable. Therefore, a first connector 45 and a second connector 46 are provided for installing the frosting roller 47. The frosting roller 47 is disposed above the leveling roller 43, and the telescopic end of the telescopic device 44 is used to contact the frosting roller 47, thereby adjusting the pressure of the frosting roller 47 on the waterproof membrane to achieve the purpose of changing the friction force.

[0050] Further, the grip assembly 2 also includes a third connecting rod 28, and the glue brushing assembly 6 includes a hose 61, a guide tube 62, a glue roller 63, a first roller seat 64 and an extrusion rod 65. The third connecting rod 28 is fixedly connected to the handle 21, the glue roller 63 is rotatably connected to the first roller seat 64, the glue roller 63 is connected to the second transmission belt 25, the third connecting rod 28 and the first roller seat 64 are both fixedly connected to the guide tube 62, the guide tube 62 is used to guide the hose 61 to extend above the glue roller, the extrusion rod 65 is slidably connected to the guide tube 62, the extrusion rod 65 extends into the guide tube 62 and abuts against the hose 61, and the first roller seat 64 is fixedly connected to the frame 1;

[0051] When the handle 21 does not move, the squeezing rod 65 squeezes the hose 61 and restricts the glue from flowing in the hose 61;

[0052] When the handle 21 moves downward, the squeezing rod 65 is separated from the hose 61, and the glue-applying roller 63 rotates.

[0053] The hose 61, the guide tube 62, the glue roller 63, the first roller seat 64 and the squeezing rod 65 are usually arranged in the working layer of the frame 1, and the side of the glue roller 63 can penetrate the partition and extend to the transmission layer, which can facilitate subsequent installation. Since the glue is a fluid, if it drips on an unwanted place, it will not only be difficult to handle, but also cause trouble to the subsequent construction. Therefore, in the present invention, the squeezing rod 65 is pressed against a certain part of the squeeze hose 61 to make the hose 61 collide with the inner wall at that place, thereby achieving a sealing effect, so that the glue will not drip freely. When the operation is needed, the handle 21 will move down, and the squeezing rod 65 will separate from the hose 61 at this time, and the glue can flow and drip to the glue roller 63, and the glue layer is arranged by the glue roller 63. The first roller seat 64 is used to support the glue roller 63.

[0054] Furthermore, the glue brushing assembly 6 also includes a mounting frame 66 , a mounting opening 67 is provided in the mounting frame 66 , and the hose 61 is connected to the mounting opening 67 .

[0055] Since there are volatile substances in the glue, a mounting frame 66 is provided for placing the glue bucket, and the bucket mouth of the glue bucket is directly mounted on the mounting opening 67 .

[0056] Further, the paving assembly 7 includes a support frame 71, a support member 72, a first support wheel 73, a second support wheel 74, an air pump 75 and an air pressure sensor 76. The support frame 71 is fixedly connected to the support member 72, the support member 72 is fixedly connected to the second connecting rod 26, the first support wheel 73 and the second support wheel 74 are rotatably connected to both sides of the support frame 71, the air pump 75 is connected to the support frame 71, and the air pressure sensor 76 is installed in the support frame 71;

[0057] When the handle 21 moves downward, the support frame 71 and the waterproof coiled material form a closed space, and the air pump 75 starts.

[0058] The support member 72 is installed in the connection layer, and the other components are installed in the working layer. Since the waterproof coiled material needs to contact with the glue, it needs to be pressed. However, the ground is not smooth and there may be sharp debris. When the waterproof coiled material is directly squeezed by rollers, the waterproof coiled material does not have enough deformation space, which may cause the waterproof coiled material to be punctured. Therefore, the present invention adopts an air pump 75 to supply air to increase the air pressure. Since the support frame 71 and the waterproof coiled material form a closed space, the waterproof coiled material can be brought into contact with the glue by applying air pressure. In this way, the force has a certain buffering property, giving the waterproof coiled material enough deformation space. The waterproof coiled material will be deformed immediately when it encounters sharp debris, thereby avoiding being scratched. In addition to laying the waterproof coiled material by increasing the air pressure by the air pump 75, the air pressure can also be reduced by the air pump 75, and the air pressure sensor 76 can be used to monitor whether the air pressure is within a predetermined range to monitor whether the waterproof coiled material itself is damaged. In addition, when the handle 21 is moved downward, the support frame 71 will not fit the ground, but the glue roller 63 will fit the ground;

[0059] In addition, since the waterproof coiled material will rub against the support frame 71 when moving, the first support wheel 73 and the second support wheel 74 are provided to reduce the friction of the waterproof coiled material.

[0060] Furthermore, the paving assembly 7 also includes a second spring 77 , and two ends of the second spring 77 are fixedly connected to the frame 1 and the support member 72 respectively.

[0061] The second spring 77 is also disposed in the connection layer. Since the support frame 71 is far away from the handle 21 , in order to prevent the reset from failing, the second spring 77 is disposed to assist the reset.

[0062] Furthermore, the storage assembly 5 includes a storage roller 51 and a second roller seat 52 , the second roller seat 52 is fixedly connected to the frame 1 , the storage roller 51 is connected to the second transmission belt 25 , and the storage roller 51 is rotatably connected to the second roller seat 52 .

[0063] The storage roller 51 and the second roller seat 52 are usually arranged in the working layer of the frame 1, and the side of the storage roller 51 can penetrate the partition and extend to the transmission layer, which can facilitate subsequent installation. Since the waterproof membrane will be protected by a cushion layer, the cushion layer is stored by the storage roller 51, and the cushion layer can also be pulled by rotating to drive the release of the entire waterproof membrane. The second roller seat 52 is used to support the storage roller 51.

[0064] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
