Description

Technical Field

[0001] The present invention belongs to the technical field of thermal insulation board assembly, and more specifically, relates to an auxiliary coating device and construction method for an exterior wall thermal insulation board adhesive based on the dot and frame method. Background Art

[0002] With the enhancement of global awareness of energy conservation and emission reduction, building energy conservation has become an important development direction in the current construction industry. Among them, the exterior wall thermal insulation system, as an important part of building energy conservation measures, has been widely used. The implementation of exterior wall insulation can not only improve the thermal performance of buildings, reduce energy consumption, but also play a role in beautifying the building exterior. Especially in cold regions, a good exterior wall thermal insulation system can significantly improve the thermal effect of buildings and reduce heating energy consumption. The exterior wall thermal insulation system usually includes two parts: exterior wall thermal insulation boards and bonding mortar, and the installation of exterior wall thermal insulation boards is a key link in exterior wall thermal insulation construction. In exterior wall thermal insulation construction, exterior wall thermal insulation boards usually use thermal insulation materials such as rock wool boards and polystyrene boards, and these thermal insulation boards need to be firmly bonded to the exterior wall of the building through bonding mortar. However, in the construction process, the uniform coating of bonding mortar and the control of the bonding rate have always been difficult problems in construction. In particular, how to ensure the coating area and bonding strength of bonding mortar to meet the specification requirements has become the main challenge in the current technology.

[0003] Currently, the coating methods of bonding mortar in exterior wall thermal insulation board construction usually include the dot and frame method, the strip bonding method, and the full bonding method. However, due to the highest "cost performance" of the dot and frame method in terms of pasting, the dot and frame method is mainly used in building construction. Specifically, construction workers usually apply the bonding mortar on the thermal insulation board by dotting according to experience, and then bond the thermal insulation board to the exterior wall of the building. Although this method is relatively simple, in the practical process, it depends on the experience and manual operation of construction workers, and there is no unified standard for the bonding position, the thickness and distribution of bonding mortar, etc., which is easy to cause uneven thickness and even affect the bonding firmness and thermal insulation effect. To make up for the deficiencies of the dot bonding method, some technologies have proposed other methods, such as controlling the distribution and thickness of bonding mortar by means of mechanical equipment or adding partition strips to the mortar.

[0004] However, these existing technologies have not completely solved the problems of the uniformity and standardization of bonding mortar in practice. On the one hand, the cost of mechanical construction equipment is high, the operation is complex, it is not easy to move, and the skill requirements for construction workers are high; on the other hand, the existing auxiliary tools have an unsatisfactory control effect on the bonding area and mortar thickness, resulting in the construction effect still unable to meet the strict requirement that the coating area of bonding mortar in the building thermal insulation standard shall not be less than 70% of the total area of the thermal insulation board. Summary of the Invention

[0005] In view of the above deficiencies or improvement requirements of the prior art, the present invention provides an auxiliary coating device and construction method for exterior wall insulation board adhesives based on the dot and frame method. By means of the sliding component, the dot and frame method die is closely attached to the insulation board, optimizing the common problem of uneven bonding in traditional dot and frame method construction, effectively ensuring that the coating of the adhesive is more uniform and precise, and improving the construction quality. Secondly, the reserved slots in the die can help construction workers easily perform the dot and frame method coating operation, greatly reducing the construction difficulty, especially reducing the risk of relying on manual experience, thereby improving the construction efficiency. In addition, through the mobile support frame and the pushing handle, the auxiliary coating device can be conveniently pushed to the construction area, improving the mobility and adaptability of the device and meeting different construction environments and construction requirements.

[0015] Further, the sliding component further includes: a connecting plate; both ends of the connecting plate are respectively connected to the two sliders and its upper surface is in the same plane as the upper surface of the slider. A bolt hole for connecting with the connecting block on one side of the dot and frame method die is arranged in the middle thereof, and it is detachably connected to the dot and frame method die through the bolt hole and the connecting block.

[0016] Further, the heat preservation board is arranged on the upper end of the second fixing plate through a heat preservation board support frame. There are two heat preservation board support frames, which are symmetrically arranged outside the sliding assembly. The heat preservation board support frame includes a support plate and a support column. One end of the support column is connected to the second fixing plate, and the other end is connected to the bottom end of the support plate. One end of the support plate is connected to the first fixing plate, and its upper surface is on the same plane as the upper surface of the slider.

[0017] Further, a push-pull handle is arranged on one side of the connecting plate away from the first fixing plate.

[0018] Further, the first fixing plate is set in a horizontal state and the second fixing plate is set in a vertical state. The moving support frame is arranged at the bottom end of the first fixing plate. A limiting member for limiting the push-pull handle is arranged in the middle of the second fixing plate. The limiting member includes a connecting rod passing through the second fixing plate and slidably connected to the second fixing plate, and two cylindrical limiting blocks respectively arranged at both ends of the connecting rod and having a size larger than that of the connecting rod.

[0019] Further, the moving support frame includes a support frame, directional wheels and brake-equipped universal wheels. The support frame is an overall square frame and is internally provided with a plurality of support rods to enhance the structural stability. There are two directional wheels and two brake-equipped universal wheels, and they are symmetrically arranged at the bottom end of the support frame.

[0020] The overall height of the moving support frame is 1 - 1.2 m.

[0021] Further, two push handles are arranged on one side of the support frame, and the push handles are not located at the same end or opposite ends as the vertical first fixing plate or the vertical second fixing plate.

[0022] Further, the dot-frame method mold is mainly made of aluminum alloy. It is an overall square plate and its surface is evenly provided with a plurality of circular through holes.

[0023] On the other hand, the present invention provides a construction method of an auxiliary coating device for an exterior wall heat preservation board adhesive based on the dot-frame method, which is realized by applying the above-mentioned auxiliary coating device, and includes the following steps:

[0029] Generally speaking, compared with the prior art by the above technical solutions conceived by the present invention, the following beneficial effects can be achieved:

[0030] 1. For the auxiliary coating device of the present invention, the dot-frame method mold is closely attached to the insulation board through the sliding assembly, optimizing the common problem of uneven bonding in the traditional dot-frame method construction, effectively ensuring that the application of the adhesive is more uniform and precise, and improving the construction quality. Secondly, the reserved slots in the mold can help the construction workers easily perform the dot-frame method coating operation, greatly reducing the construction difficulty, especially reducing the risk of relying on manual experience, thereby improving the construction efficiency. In addition, the auxiliary coating device can be conveniently pushed to the construction area through the mobile support frame and the push handle, improving the mobility and adaptability of the device, and meeting different construction environments and construction requirements.

[0031] 2. For the auxiliary coating device of the present invention, the sliding grooves are arranged on both sides of the slide rail, and the pulley in the slider groove area is slidably connected to the slide rail, thus avoiding the problem that the working of the sliding assembly is affected due to the dropping of the adhesive.

[0032] 3. For the auxiliary coating device of the present invention, the upper surfaces of the slider, the connecting plate and the support plate are set in the same plane, so that a rectangular groove for applying the adhesive can be conveniently reserved between the dot-frame method mold and the insulation board through the connection block, effectively controlling the application range and thickness of the adhesive, thereby ensuring the construction accuracy. At the same time, combined with the through holes on the dot-frame method mold, the adhesive can be evenly distributed on the surface of the insulation board, ensuring the consistency and firmness of the bonding effect, thus helping to improve the efficiency of the coating operation, reducing the error of manual operation, reducing the labor intensity of the construction workers, and improving the operation quality.

[0033] 4.

At the same time, the horizontally placed insulation board is more stable during handling, reducing unnecessary tilting or sliding, lowering the risk during handling, and enhancing the construction safety. In addition, by pulling the limiting member and cooperating with the use of the push-pull handle, the point-frame method mold can be conveniently hovered and precisely attached to the insulation board, thus helping to improve the operation progress, reducing the manual labor intensity, and ensuring the consistency and quality of the coating work.

[0040] Embodiment 1

[0041] As Figure 1 and Figure 2As shown in the figure, Embodiment 1 of the present invention provides an auxiliary coating device for exterior wall insulation board adhesive based on the dot and frame method, including: a first fixing plate 1, a second fixing plate 2, a dot and frame method mold 3, a sliding assembly 4, a moving support frame 5, and a pushing handle 6; the first fixing plate 1 is arranged at one end edge of the second fixing plate 2; the dot and frame method mold 3 is slidably connected to the second fixing plate 2 through the sliding assembly 4; the moving support frame 5 is arranged at the bottom end of the first fixing plate 1 or the second fixing plate 2; the pushing handle 6 is arranged on one side of the moving support frame 5; during use, the dot and frame method mold 3 is closely attached to the insulation board 7 through the sliding assembly 4, optimizing the problem of uneven bonding commonly found in traditional dot and frame method construction, effectively ensuring that the adhesive is applied more evenly and precisely, and improving the construction quality; secondly, the reserved slot holes in the mold can help construction workers easily achieve dot and frame method coating operations, greatly reducing the construction difficulty, especially reducing the risk of relying on manual experience, thereby improving the construction efficiency; in addition, through the moving support frame 5 and the pushing handle 6, the auxiliary coating device can be conveniently pushed to the construction area, improving the mobility and adaptability of the device, and meeting different construction environments and construction requirements.

[0042] In an optional embodiment, the sliding assembly 4 includes: two groups of parallel sliding rails 41 and sliders 42; the sliding rails 41 are arranged at the upper end of the second fixing plate 2 and corresponding sliding grooves 411 are arranged on both sides thereof; the slider 42 is an overall concave block, which is arranged at the upper end of the sliding rail 41 and the groove width thereof is adapted to the width of the sliding rail 41.

[0043] One end of the sliding rail 41 contacts the first fixing plate 1, and a stop block 412 is arranged at one end to prevent the slider 42 from coming off.

[0044] Pulley 421 adapted to the sliding groove 411 is symmetrically arranged on the inner wall of the groove area of the slider 42.

[0045] It should be noted that through the above design, the sliding groove 411 is arranged on both sides of the sliding rail 41, and the pulley 421 in the groove area of the slider 42 is slidably connected to the sliding rail 41, thereby avoiding the problem that the sliding assembly 4 fails to work properly due to the dropping of the adhesive.

[0046] In an optional embodiment, the dot and frame method mold 3 is mainly made of aluminum alloy, and it is an overall square plate with a number of circular through holes evenly arranged on its surface.

[0047] The sliding assembly 4 further includes: a connecting plate 422; both ends of the connecting plate 422 are respectively connected to the two sliders 42, and its upper surface is on the same plane as the upper surface of the slider 42. A bolt hole (not shown) for connecting with a connecting block 31 on one side of the dot and frame method mold 3 is arranged in the middle thereof, and the dot and frame method mold 3 is detachably connected through the bolt hole and the connecting block 31.

[0048] The heat preservation board 7 is arranged at the upper end of the second fixed plate 2 through a heat preservation board support frame 71. There are two heat preservation board support frames 71, which are symmetrically arranged outside the sliding assembly 4. The heat preservation board support frame 71 includes a support plate 711 and a support column 712. One end of the support column 712 is connected to the second fixed plate 2, and the other end is connected to the bottom end of the support plate 711. One end of the support plate 711 is connected to the first fixed plate 1, and its upper surface is on the same plane as the upper surface of the slider 42.

[0049] One side of the slider 42 close to the heat preservation board 7 and one side of the point-frame method mold 3 close to the heat preservation board 7 are on the same plane.

[0050] It should be noted that through the above design, the upper surfaces of the slider 42, the connecting plate 422 and the support plate 711 are set to be on the same plane, so that it is convenient to reserve a rectangular groove for applying the adhesive between the point-frame method mold 3 and the heat preservation board 7 through the connecting block 31, effectively controlling the spreading range and thickness of the adhesive, thus ensuring the construction accuracy. At the same time, combined with the through holes on the point-frame method mold 3, the adhesive can be evenly distributed on the surface of the heat preservation board, ensuring the consistency and firmness of the bonding effect, which helps to improve the efficiency of the spreading operation, reduce the errors of manual operation, reduce the labor intensity of construction workers, and improve the operation quality.

[0051] In an alternative embodiment, a push-pull handle 423 is provided on one side of the connecting plate 422 away from the first fixed plate 1, which is used to enhance the moving flexibility of the point-frame method mold 3, thereby helping to enhance the overall construction efficiency.

[0052] In an alternative embodiment, the mobile support frame 5 includes: a support frame 51, a directional wheel 52 and a caster wheel 53 with a brake; the support frame 51 is a square frame as a whole, and several support rods are arranged inside to enhance the structural stability; there are two directional wheels 52 and two caster wheels 53 with a brake, and they are symmetrically arranged at the bottom end of the support frame 51.

[0053] The overall height of the mobile support frame 5 is 1 - 1.2 m, which fully considers the human activity law and has the characteristics of ergonomics, thus effectively improving the operation comfort and efficiency of the user.

[0054] Embodiment 2

[0055] Such as Figure 3As shown, on the basis of Embodiment 1, in Embodiment 2 of the present invention, the first fixing plate 1 is set horizontally and the second fixing plate 2 is set vertically; the moving support frame 5 is arranged at the bottom end of the first fixing plate 1; a limiting member 21 for limiting the push-pull handle 423 is arranged in the middle of the second fixing plate 2. The limiting member 21 includes: a connecting rod 211 passing through the second fixing plate 2 and slidably connected to the second fixing plate 2, and two cylindrical limiting blocks 212 respectively arranged at both ends of the connecting rod 211 and having a size larger than that of the connecting rod 211. It can be understood that by setting the first fixing plate 1 horizontally and the second fixing plate 2 vertically, the insulation board 7 and the point-frame method mold 3 can be set horizontally, enabling the operator to apply the adhesive more easily. At the same time, the horizontally placed insulation board 7 is more stable during handling, reducing unnecessary tilting or sliding, lowering the risk during handling, and enhancing the safety of construction; in addition, by pulling the limiting member 21 and cooperating with the use of the push-pull handle 423, the point-frame method mold 3 can be conveniently hovered and precisely attached to the insulation board 7, thereby helping to improve the operation progress, reducing the manual labor intensity, and ensuring the consistency and quality of the application work.

[0056] It can be understood that the connecting rod 211 is slidably connected to the second fixing plate 2 through a through hole adapted to the middle of the second fixing plate 2, and the large-sized limiting blocks 212 at both ends thereof prevent it from falling off. By cooperating with the limiting block 212 on one side of the push-pull handle 423, the connecting rod 211 enables the push-pull handle 423 to hover above the insulation board 7 for the convenience of switching the insulation board 7.

[0057] It can be understood that after the insulation board support frame 71 is erected vertically, it can still serve as a limiting member to limit the horizontal position of the insulation board 7 and cooperate with the sliding assembly 4 to map the slot holes for adhesive application on the insulation board 7 by the point-frame method mold 3.

[0058] In an optional embodiment, two push handles 6 are arranged on one side of the support frame 51, and the push handles 6 are not located at the same end or opposite ends as the vertical first fixing plate 1 or the vertical second fixing plate 2, so that when the auxiliary application device is conveniently pushed through the push handles 6 to be transferred to the construction area, the vision is not blocked by the first fixing plate 1 or the second fixing plate 2, thereby effectively enhancing the transfer safety.

[0059] Other technical features are the same as those in Embodiment 1 and can achieve the same technical effects, which will not be elaborated one by one here.

[0062] S1: Move the auxiliary coating device to the construction area by pushing the handle 6, and stably park the auxiliary coating device by using the brake-equipped universal wheels 53;

[0063] S2: Connect the dot-frame method mold 3 adapted to the insulation board 7 to be coated with adhesive to the connecting plate 422 through the connecting block 31;

[0064] S3: Press the insulation board 7 tightly against the support plate 711, and make the dot-frame method mold 3 fit tightly with the insulation board 7 by pushing and pulling the handle 423. Then, manually apply the adhesive on the surface of the insulation board 7 according to the dot-frame method mold 3;

[0065] S4: After completing Step S3, pull the push-pull handle 423 to make the dot-frame method mold 3 away from the insulation board 7, and supplement the adhesive in the area where the insulation board 7 is in contact with the connecting block 31. Then, take away the insulation board 7 that has completed the adhesive coating;

[0066] S5: Repeat Step S3 and Step S4 to complete the coating operation of all insulation boards 7. Then, clean the auxiliary coating device for the next construction operation.

[0067] Other technical features are the same as those in Embodiment 1 and can achieve the same technical effects, which will not be elaborated here one by one.
