Description

Technical Field

[0001] The present invention belongs to the technical field of building waterproof construction, and in particular relates to a method for laying asphalt coiled material for building houses, a laying device and a use method thereof. Background Art

[0002] Asphalt membranes are commonly used to effectively waterproof roofs, basements, and other key structures in a house that require waterproofing. However, traditional asphalt membrane laying technology does present a series of challenges and problems in its practical application:

[0003] First, the current installation of asphalt membranes relies heavily on the experience and technical skills of the construction workers, which directly leads to inconsistent construction quality. Due to the varying skills of different construction workers, even the same construction process can produce vastly different results depending on the individual. This discrepancy not only affects the aesthetics of the finished product but, more importantly, affects the actual performance and durability of the waterproofing layer, making it difficult to ensure that every detail meets the expected optimal waterproofing standards.

[0004] Secondly, the hot-melt method, a common method for laying asphalt membranes, offers strong adhesion and excellent waterproofing, but its safety and environmental compatibility are questionable. Using a flame spray gun to heat the membrane and secure it to the base layer, particularly in enclosed or semi-enclosed spaces, can produce harmful gases, posing a potential health threat to construction workers. Furthermore, the hot-melt method has specific temperature requirements. In cold weather, the material hardens, making heating more difficult. This not only prolongs construction time but also reduces efficiency and increases costs.

[0005] Finally, whether using a flame spray gun or an electric heating element to heat asphalt membranes, a common problem is uneven heating. This can cause some areas of the membrane to not fully melt, affecting the integrity and sealing of the entire waterproofing layer, and thus weakening the waterproofing effect. Excessive heating can damage the membrane's underlying structure, affecting its service life and waterproofing performance. Summary of the Invention

[0006] In view of this, the object of the present invention is to provide a method for paving asphalt roll materials for building houses, a paving device and a method of use, so as to solve the problems existing in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the technical solution of the present invention is a method for laying asphalt coiled material for building houses, which comprises the following steps:

[0008] S1. Preliminary preparation: processing of the construction area;

[0009] S2. Preheating treatment: Fix one end of the coil and preheat the coil evenly through the heating component to improve the flexibility of the coil;

[0010] S3. Heating treatment: The preheated coil is heated evenly on the back side by a heating component until the asphalt begins to melt and become soft.

[0011] S4. Laying process: Lay the heated and melted coiled material to the predetermined position and compact it with a pressing roller to ensure that the coiled material is in close contact with the base layer of the construction area;

[0012] S5. Overlap treatment: Appropriate overlap width should be maintained between adjacent rolls to ensure the sealing effect.

[0013] Preferably, in the laying process of step S4, a heated pressing roller component or a pressing roller component capable of self-heating is used to lay the heated and melted coiled material to a predetermined position.

[0014] Furthermore, in the preheating treatment of step S2 and the heating treatment of step S3, both the heat-generating component and the heating component use electric heating elements, and the area between the heat-generating component and the heating component is the heating space; the heating component is equipped with a first fan, which uses the first fan to evenly transfer the heat generated by the heating component to the coil.

[0015] Furthermore, the heating component is equipped with a second fan, which is used to extract the heat generated by the heating component from the heating space; the first fan and the second fan allow the coil to be gradually heated between the heating component and the heating component to ensure that the coil is heated evenly; at the same time, the second fan is used to locally exhaust the gas volatilized by the heated coil.

[0016] In order to solve the above technical problems, the second technical solution of the present invention is a device for laying asphalt roll materials for building houses, and the laying device is applied to steps S2 to S5 in the method for laying asphalt roll materials for building houses described in the first technical solution; the laying device is composed of a heating component, a heating component and a pressure roller component, the heating component is equipped with a second fan, and the heating component is equipped with a first fan; the heating component has a hollow cylinder, the axial direction of the hollow cylinder is parallel to the width of the roll material, the second fan is arranged on the two axial end faces of the hollow cylinder, and the hollow cylinder is provided with an air inlet facing the heating component; the air in the heating area of the roll material is circulated by the second fan, so as to achieve uniform heating of the roll material and local exhaust.

[0017] Preferably, the laying device has a heating space, the heating space has a feed port and a discharge port for the coils to enter and exit, the feed port and the discharge port are both provided with guide rollers above the coils, the heating component is provided at the feed port of the heating space and below the coils, the heating component is located in the heating space and below the coils; the heating space is provided with an air inlet on the side close to the heating component, and the first fan is provided at the air inlet; the air flow enters the heating space from the air inlet through the first fan, brings the heat generated by the heating component to the coils, and heats the coils evenly; then, under the action of the second fan, enters the heating component through the air inlet and preheats the coils along the way; the air flow is then discharged from the heating space by the second fan, thereby playing a role of local exhaust.

[0018] Furthermore, the pressure roller component is composed of a support frame, a mounting frame and a pressure roller. A vibration component is arranged between the support frame and the mounting frame. A heating tube is arranged inside the pressure roller, and the pressure roller is rotatably arranged on the mounting frame. Under the action of the vibration component, the pressure roller vibrates during the coil laying process, which plays a role in enhancing the compaction effect.

[0019] Furthermore, the vibration assembly includes a driving disk rotatably arranged on the support frame, a slider slidably arranged on the mounting frame, and a connecting rod for connecting the driving disk and the slider, the connecting rod and the driving disk and the connecting rod and the connecting rod are connected by movable spherical joints, and the connecting rod and the driving disk are eccentrically arranged; when the driving disk rotates, the mounting frame is driven by the connecting rod and the slider to move up and down on the support frame, thereby achieving a vibration effect; by changing the position of the slider on the mounting frame, the vibration effect of the mounting frame can be adjusted.

[0020] In order to solve the above technical problems, the third technical solution of the present invention is a method for using the asphalt coil paving device for building houses described in the second technical solution, and the method comprises the following steps:

[0021] 1) Preheating stage: Turn on the second fan on the heating component to generate air flow in the hollow cylinder of the heating component; preheat the coiled material that is about to enter the heating space to ensure that subsequent heating is more uniform and effective;

[0022] 2) Coil Heating: The asphalt coil is guided by guide rollers into the feed port of the heating chamber. The first fan is turned on to allow air to enter the heating chamber from the air inlet and carry the heat generated by the heating element to the coil, achieving uniform heating of the coil. During this process, the heating element continues to be heated by the second fan, allowing air to enter the heating element through the air inlet and further preheat the coil along the way.

[0023] 3) Compaction: After the coil is heated, it reaches the pressure roller. At this time, the vibration assembly is started. Through the cooperation between the drive plate, slider and connecting rod, the pressure roller produces a vibrating effect on the mounting frame, which enhances the compaction effect. The vibration effect can be adjusted by adjusting the position of the slider to ensure the best compaction quality.

[0024] The technical effects of the present invention are mainly reflected in the following aspects:

[0025] During the preheating phase, the second fan on the heating element generates air flow within the hollow cylinder, evenly distributing the heat and directing it into the heating space through the air inlet, thereby preheating the coils entering the heating space. During the coil heating phase, the first fan directs the heat generated by the heating element toward the coils, achieving further uniform heating. This dual heating mechanism not only improves the overall heating efficiency of the coils but also ensures uniformity from preheating to the final heating process, effectively avoiding localized overheating or insufficient heating, and providing optimal conditions for subsequent laying.

[0026] Before entering the heating chamber, the membrane passes through a heating element for preliminary preheating. This step effectively increases the membrane's flexibility, allowing it to more easily adapt to the shape of the substrate and adhere better. This process of increasing the membrane's flexibility is crucial for subsequent heating, as it reduces stress concentration in the membrane at high temperatures and helps ensure a more uniform and efficient heating process, thereby improving the waterproofing layer's sealing and durability.

[0027] By rationally positioning the primary and secondary fans and precisely controlling their operating conditions, the heat transfer path within the heating space can be effectively optimized. For example, the secondary fan evenly distributes heat generated by the heating components and allows it to enter the heating space through the air inlet, while the primary fan directly directs the heat generated by the heating components toward the coiled material. This design not only improves heat utilization and reduces energy waste, but also ensures that the coiled material receives sufficient heat throughout the heating process, promoting optimal melting of the coiled material and improving laying quality.

[0028] The vibration assembly within the pressure roller, through the coordination of a drive plate, slider, and connecting rod, vibrates the roller during laydown, enhancing the density and fit between the roll and the base layer. Furthermore, the built-in heating element provides additional heat during the compaction process, further promoting a good bond between the roll and the base layer and improving the sealing performance and service life of the waterproof layer.

DETAILED DESCRIPTION

[0036] The following is a further detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings, so that the technical solutions of the present invention are easier to understand and grasp. In the embodiments, it should be understood that the terms "middle", "upper", "lower", "top", "right", "left end", "above", "back", "middle" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, in this specific embodiment, if the connection or fixing method between the components is not particularly specified, the connection or fixing method can be fixed by bolts or pins commonly used in the prior art, or by pin connections, etc. Therefore, they will not be described in detail in this embodiment.

[0037] The method and device for laying asphalt roll materials for building houses provided by the present invention are mainly used for asphalt roll material laying construction in roofs, basements and other key structures of houses that require waterproofing, but are not limited to this and can also be used in other identical or similar production processes.

[0038] Example 1

[0039] See also Figure 1 In this embodiment, a method for laying asphalt coiled material for building a house is provided, and the method comprises the following steps:

[0040] S1. Preliminary preparation: Preparation of the area to be constructed, including cleaning, leveling and other preparatory work to ensure that the area to be constructed is suitable for laying asphalt membrane.

[0041] S2. Preheating treatment: Fix one end of the coil and preheat the coil evenly through the heating component 1 to improve the flexibility of the coil. During this process, the heating component 1 is also equipped with a second fan to extract the heat generated by the heating component 1 from the heating space to avoid local overheating. At the same time, it helps to remove the gas volatilized by the heated coil to ensure the safety of the working environment.

[0042] S3. Heating treatment: The preheated coil is passed through the heating element 2 to evenly heat the back of the coil until the asphalt begins to melt and become soft. The heating element 2 is equipped with a first fan, which is responsible for evenly transferring the heat generated by the heating element 2 to the coil, ensuring that the coil can obtain uniform heat distribution and gradually increase in temperature.

[0043] S4. Laying process: The heated and melted coiled material is laid to the predetermined position and compacted with the pressing roller 3 to ensure that the coiled material is in close contact with the base layer in the area to be constructed; this ensures a close contact between the coiled material and the base layer, thereby improving the overall sealing and durability of the waterproof layer.

[0044] S5. Overlap treatment: Appropriate overlap width should be maintained between adjacent rolls to ensure sealing effect and prevent moisture penetration.

[0045] In the laying process of step S4, the heated pressure roller component 3 or the pressure roller component 3 capable of self-heating is used to lay the heated and melted coiled material to the predetermined position. In the preheating process of step S2 and the heating process of step S3, both the heating component 1 and the heating component 2 use electric heating elements, and the area between the heating component 1 and the heating component 2 is the heating space; the heating component 2 is equipped with a first fan, which is used to evenly transfer the heat generated by the heating component 2 to the coiled material. The heating component 1 is equipped with a second fan, which is used to extract the heat generated by the heating component 1 from the heating space; the first fan and the second fan allow the coiled material to be gradually heated between the heating component 1 and the heating component 2 to ensure that the coiled material is heated evenly; at the same time, the gas volatilized by the heated coiled material is locally exhausted with the help of the second fan. Specifically, preheating the material using a specially designed heating element 1 (step S2) ensures that the roll reaches optimal flexibility before installation. This not only helps reduce quality variations caused by human factors but also improves the integrity and sealing of the final waterproof layer. Heating element 2 uniformly heats the back of the roll (step S3), overcoming the uneven heating problem associated with traditional hot-melt methods. This method ensures that every area of the roll is fully heated to the ideal state, thereby enhancing waterproofing performance. The coordinated use of the first and second fans ensures uniform heating of the roll from preheating to heating, effectively avoiding quality issues caused by uneven heating. Furthermore, the localized exhaust design protects the health of construction workers. The dual heating mechanism of heating element 1 and heating element 2, combined with the functions of the first and second fans, ensures uniform heating of the roll from preheating to heating. This design not only improves the roll's flexibility, laying a good foundation for subsequent installation, but also ensures that the roll reaches optimal working condition before installation, avoiding quality issues caused by localized overheating or insufficient heating.

[0046] Example 2

[0047] See also Figure 2 This embodiment discloses a device for laying asphalt coil for building construction. The device is applied to steps S2 to S5 of the asphalt coil laying method for building construction described in Example 1 to improve overall construction quality and efficiency. The device comprises a heating element 1, a heating element 2, and a pressure roller element 3. The heating element 1 is equipped with a second fan, and the heating element 2 is equipped with a first fan.

[0048] See also Figure 3The heating element 1 comprises a hollow cylinder 11, the axial direction of which is parallel to the width of the coil. The second fan is disposed on the two axial end faces of the hollow cylinder 11. The hollow cylinder 11 is provided with an air inlet 12 facing the heating element 2, facilitating airflow and improving preheating. The second fan directs air flow through the coil heating area, achieving uniform heating and localized exhaust. The laying device comprises a heating space having a feed port 21 and a discharge port 22 for the coil to enter and exit. The feed port 21 and the discharge port 22 are both provided with guide rollers 23 above the coil to ensure smooth entry and exit of the coil. The heating component 1 is arranged at the feed inlet 21 of the heating space and is located below the coil, and the heating component 2 is located in the heating space and is located below the coil; the heating space is provided with an air inlet 24 on the side close to the heating component 2, and the first fan is arranged at the air inlet 24 to evenly transfer the heat generated by the heating component 2 to the surface of the coil; the heating component 1 is arranged at the feed inlet 21, and the heating component 2 is located in the heating space, and they work together in the preheating and heating process of the coil.

[0049] See also Figure 1 The air flow enters the heating space from the air inlet 24 through the first fan, brings the heat generated by the heating component 2 to the coil, and heats the coil evenly; then, under the action of the second fan, enters the heating component 1 through the air inlet 12 and preheats the coil along the way; the air flow is then discharged from the heating space by the second fan, thereby playing a local exhaust role.

[0050] See also Figure 5 、 Figure 6The pressure roller assembly 3 consists of a support frame 31, a mounting frame 32, and a nip roller 33. The support frame 31 serves as the basic structure of the entire pressure roller assembly 3, providing stable support and serving as a bridge connecting other components (such as the mounting frame 32 and the drive disc 341). The mounting frame 32 directly supports the nip roller 33, allowing the nip roller 33 to rotate on it. It is also part of the vibration assembly 34, which achieves a vibration effect by moving up and down. A vibration assembly 34 is provided between the support frame 31 and the mounting frame 32. The nip roller 33 is equipped with a heating pipe to achieve self-heating during the paving process. This not only helps soften the asphalt so that it better adheres to the base layer, but also enhances the compaction effect. The nip roller 33 is rotatably mounted on the mounting frame 32, allowing the nip roller 33 to rotate freely on the mounting frame 32, ensuring that pressure is applied evenly throughout the paving process. Under the action of the vibration assembly 34, the nip roller 33 vibrates during the roll material laying process, which serves to enhance the compaction effect. In practical application, the coiled material to be laid can be placed on the pressure roller component 3 to increase the counterweight, thereby ensuring the overall stability of the equipment when the pressure roller 33 vibrates during operation.

[0051] See also Figure 5 、 Figure 6 The vibration assembly 34 includes a drive disk 341 rotatably mounted on the support frame 31, a slider 342 slidably mounted on the mounting frame 32, and a connecting rod 343 connecting the drive disk 341 and the slider 342. The connecting rod 343 and the drive disk 341, as well as the connecting rod 343 and the connecting rod 343, are connected using movable ball joints to ensure flexible movement. The connecting rod 343 and the drive disk 341 are eccentrically positioned; the drive disk 341 is equipped with a drive motor. When the drive disk 341 rotates, power is transmitted to the slider 342 via the connecting rod 343, thereby driving the mounting frame 32 to move up and down. The connecting rod 343 and the slider 342 drive the mounting frame 32 up and down on the support frame 31, thereby producing a vibration effect. By changing the position of the slider 342 on the mounting frame 32, the vibration amplitude and frequency can be adjusted, thereby achieving the desired vibration effect of the mounting frame 32.

[0052] Example 3

[0053] This embodiment discloses a method for using the asphalt coil paving device for building houses described in the second embodiment, and the method comprises the following steps:

[0054] 1) Preheating Phase: The second fan on heating element 1 is activated, creating air flow within the hollow cylinder 11 of heating element 1. This process helps evenly distribute the heat generated by heating element 1 and directs it into the heating chamber through air inlet 12. Before entering the heating chamber, the coil undergoes preliminary preheating by passing through heating element 1. This step improves the coil's flexibility, prepares it for subsequent heating, and ensures a more uniform and efficient heating process.

[0055] 2) Coil Heating: The asphalt coil is guided through guide rollers 23 into the feed port 21 of the heating chamber. The first fan is activated, allowing air to enter the heating chamber through air inlet 24 and carry the heat generated by the heating element 2 to the coil, achieving uniform heating of the coil. This step is crucial to ensure that the coil is fully melted and softened, directly affecting the final paving quality.

[0056] During this process, the heating component 1 continues to use the second fan to allow air to enter the heating component 1 through the air inlet 12 and further preheat the coil along the way; this dual heating mechanism not only improves the heating efficiency, but also ensures the uniformity of heating of the coil.

[0057] 3) Compaction: After the coil is heated, it reaches the pressure roller component 3. At this time, the vibration component 34 is started. Through the cooperation between the drive plate 341, the slider 342 and the connecting rod 343, the pressure roller 33 generates a vibration effect on the mounting frame 32, thereby enhancing the compaction effect. The vibration effect can be adjusted by adjusting the position of the slider 342 to ensure the best compaction quality.

[0058] In addition, as common knowledge in the industry, the first fan, the second fan and the related heating components mentioned above are common knowledge, so their principles and structures will not be described in detail.

[0059] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
