Description

TECHNICAL FIELD

[0001] The utility model relates to related technical field of building construction especially relates to a gap cleaning device for waterproof construction of outer wall. BACKGROUND

[0002] In the waterproof construction of outer wall, if there are dust, chippings, dirt and other sundries in the gap, an isolation layer will be formed between the waterproof material and the gap wall, hindering the close contact of the waterproof material and the wall. This will result in that the waterproof material cannot fully play the bonding role, reducing the adhesion between the waterproof coating and the wall, and easily causing problems such as peeling and drumming, which seriously affects the waterproof effect.

[0003] The existing cleaning work usually uses a brush to clean the gap, but the length and structure of the conventional cleaning brush are limited, and it is difficult to penetrate into the deep or narrow gap of the outer wall, so that some dust and sand hidden in the deep place cannot be touched, which seriously affects the cleaning effect and further affects the waterproof quality after the construction is completed.

[0022] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0023] Embodiment 1, with reference to Figures 1 to 5 The utility model provides a kind of outer wall waterproof construction gap cleaning device, including first pipe body 1, first pipe body 1 one end and other end are equipped with through opening 2, first pipe body 1 is connected with second check valve 5, first pipe body 1 other end is connected with first check valve 3, first check valve 3 and first pipe body 1 are connected with rubber air bag 4, first check valve 3 one end is connected with second pipe body 6, first check valve 3 and second check valve 5 play the core airflow control effect in device.When pressing rubber air bag 4, the gas pressure in rubber air bag 4 rises, pressure acts on first check valve 3 and makes it open, at this time, gas can only unidirectionally flow to second pipe body 6, ensure the directionality and effectiveness of jet, accurately deliver airflow to outer wall crack, effectively blow dust and chippings and other sundries.Effective to avoid gas backflow when rubber air bag 4 restores original shape, internal gas pressure reduces, second check valve 5 opens, and external air can smoothly enter rubber air bag 4, reserves sufficient gas for next time jet.The design of this check valve effectively avoids gas backflow, ensures the sustained and stable operation of the device, improves cleaning efficiency, second pipe body 6 is equipped with brush body 7, through the collaborative operation of rubber air bag 4, first check valve 3, second check valve 5 and brush body 7, dust, chippings and other sundries in deep part of outer wall gap can be effectively cleaned.Pressing rubber air bag 4 makes airflow jet to crack through second pipe body 6, can blow hidden sundries, brush body 7 sweeps synchronously, compared with traditional brush cleaning, it is more thorough, greatly improves cleaning efficiency and quality, provides good base layer for subsequent waterproof construction, prevents sundries from affecting waterproof material bonding effect, avoids waterproof coating peeling, drumming and other problems, enhances the waterproof performance of outer wall.

[0024] In this embodiment, the first pipe body 1 is connected with the first ring body 9, the first ring body 9 is movably connected with the second ring body 10, and the second ring body 10 is connected with the rope body 11. When performing the gap cleaning work of the waterproof construction of the outer wall, especially in the high-altitude outer wall operation scene, the staff can firmly connect one end of the rope body 11 with the safety waistband or other reliable fixed points of the body. In this way, the device can always accompany the staff during movement, avoiding safety accidents or equipment damage caused by accidental falling. At the same time, during operation, the staff can conveniently clean the cracks at different positions by holding the rubber air bag 4 and adjusting the position of the brush body 7, without having to worry about the fixation of the device with both hands, greatly improving the convenience and efficiency of operation. The brush body 7 is threadedly connected with the second pipe body 6, and the second pipe body 6 movably penetrates the hollow area of the brush body 7. This connection mode provides great convenience for the user. The user can easily replace the brush body 7 of different materials, hardness or shapes according to different outer wall materials and crack conditions, such as using a hard brush body 7 for stubborn dirt and a soft brush body 7 for a relatively fragile wall surface, so as to achieve a more targeted cleaning effect. The second pipe body 6 is connected with the ring body 8, the ring body 8 is in contact with the brush body 7, and the setting of the ring body 8 further enhances the stability of the connection between the brush body 7 and the second pipe body 6, preventing the brush body 7 from shaking or moving during use, and ensuring the accuracy and efficiency of the cleaning operation. The end of the second pipe body 6 away from the rubber air bag 4 is designed as a circular table, which is convenient for deepening the outer wall cracks, so that the air jet and cleaning can more effectively act on the deep part of the cracks. The rubber air bag 4 is made of natural rubber, mainly because of its excellent elasticity and flexibility. During repeated pressing, natural rubber can quickly recover its shape, ensuring the rapid intake and discharge of gas and maintaining a stable air jet rhythm. At the same time, natural rubber has a certain wear resistance and can withstand frequent friction with the hands and other parts, prolonging the service life. Its good air tightness also helps to maintain the gas pressure and ensure the air jet effect. The first pipe body 1 and the second pipe body 6 are both made of hard plastic material to ensure the stability of the gas conveying process and the overall structural strength of the device.

[0025] The working principle of the embodiment is as follows: when in use, one end of the rope body 11 can be connected with some articles of the staff, such as a waistband, etc. After completion, the staff can conveniently carry when ascending or descending at the outer wall. When moving to the crack, holding the rubber air bag 4 and directing one end of the brush body 7 towards the crack, the brush body 7 can clean the crack, and the rubber air bag 4 can be pressed. By virtue of the property that the rubber air bag 4 can restore its original shape after deformation, the cooperation of the first one-way valve 3 and the second one-way valve 5 can jet the airflow at the second pipe body 6 into the crack for further cleaning work.

[0026] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
