Description

Technical Field

[0001] The present application relates to the technical field of building exterior walls, and in particular to a device for detecting the bonding strength of exterior wall facing tiles of a building. Background Art

[0002] Exterior wall facing tiles, as decorative building products, are often used to beautify buildings, and the exterior wall facing tiles are bonded to the surface of the building exterior wall by means of adhesion. If, during the construction process, due to unqualified construction materials or non-standard operation of construction workers, the bonding strength between the exterior wall facing tiles and the wall will gradually decrease over time. When the bonding force is insufficient, the facing tiles may be partially detached from the base layer, thus forming a hollow drum. If no reinforcement is carried out, the area of the hollow drum will gradually increase, and ultimately the facing tiles will completely detach from the base layer and cause safety accidents such as high-altitude falls.

[0003] At present, one of the detection methods for defects in the exterior wall facing of buildings is the knocking method. Often, personnel need to continuously knock on the building exterior wall with a knocking hammer and judge by listening to the sound. However, long-term knocking operations will result in a relatively high working intensity for the personnel. Utility Model Content

[0004] In order to reduce the working intensity of personnel, the present application provides a device for detecting the bonding strength of exterior wall facing tiles of a building.

Detailed Description of the Embodiment

[0018] The following further describes the present application in detail Figure 1-2 with reference to the attached

[0019] The embodiment of the present application discloses a device for detecting the bonding strength of exterior wall facing bricks of a building.

[0020] Refer to Figure 1, the bonding strength detection device for exterior wall facing tiles of a building includes a base 1, a bracket 2 fixedly connected to the base 1, and a knocking mechanism 3 arranged on the bracket 2. The bracket 2 is vertically arranged. The knocking mechanism 3 includes a number of rotating shafts 31 rotatably connected to the bracket 2 through bearings. The number of rotating shafts 31 is longitudinally distributed along the bracket 2, and the rotating shafts 31 are horizontally arranged and parallel to the exterior wall. An extension rod 32 is welded to the rotating shaft 31. The extension rod 32 is threadedly and detachably connected with a knocking hammer 33 for knocking the facing tiles. The applicable type of knocking hammer 33 can be replaced according to different exterior wall conditions. A sound sensor 34 is installed at a position of the extension rod 32 close to the knocking hammer 33. In this embodiment, the sound sensor 34 can adopt a pickup to receive and analyze the sound reflected from the wall surface, and judge the hollow position and area according to the acoustic characteristics. Since the pickup and related equipment used in cooperation are all prior arts, and this application does not focus on the pickup, it will not be elaborated here. The bracket 2 is provided with a driving component 4 for driving the rotating shaft 31 to rotate, and the driving component 4 is connected to the rotating shaft 31.

[0021] Refer to Figure 1 And Figure 2 , the driving component 4 includes a gear 41 coaxially and fixedly connected to the rotating shaft 31. A vertical rack 42 is slidably connected to the bracket 2 longitudinally. The rack 42 meshes with the gear 41. A vertical electric push cylinder 43 is installed at the bottom of the bracket 2. The output shaft of the electric push cylinder 43 is fixedly connected to the lower end of the rack 42. The sliding mode of the rack 42 is as follows: a T-shaped groove 44 is longitudinally opened on the side wall of the bracket 2, and a T-shaped block 45 is slidably connected in the T-shaped groove 44. The protruding end of the T-shaped block 45 is fixedly connected to the side wall of the rack 42. Thus, the electric push cylinder 43 drives the rack 42 to move up and down, driving the rotating shaft 31 to rotate, so that the extension rod 32 can drive the knocking hammer 33 to knock the exterior wall.

[0022] Refer to Figure 1 , a horizontal cross bar 5 is welded to the upper end of the bracket 2. Pulley 51 is rotatably connected to both the cross bar 5 and the end of the base 1 close to the exterior wall. The pulley 51 contacts the exterior wall, and the axis of the pulley 51 is vertical. Secondly, wheels (not shown in the figure) are installed on the lower surface of the base 1. Thus, the applicable type of knocking hammer 33 can be replaced according to different exterior wall conditions. For example, when replacing it with a knocking hammer 33 with a pointed head, the tip of the knocking hammer 33 can be made to contact the corner of the facing tile. Then, by pushing the base 1, the tip gently slides towards the middle of the facing tile, and the sound is collected by the pickup, that is, the sound emitted during the sliding process, to determine the area or degree of the hollow, thereby expanding the usage scenario.

[0023] Refer to Figure 1, the base 1 is provided with a lifting mechanism 6. The lifting mechanism 6 includes a screw rod 61 rotatably connected to the base 1 through a bearing. The screw rod 61 is vertically arranged and threadedly penetrates through the bracket 2. The base 1 is fixedly connected with a vertical limiting rod 62, and the limiting rod 62 slidably penetrates through the bracket 2. The base 1 is provided with a rotating assembly 7. The rotating assembly 7 includes a motor 71 installed on the base 1. A worm 72 is coaxially fixed to the output shaft of the motor 71. A worm gear 73 meshing with the worm 72 is fixedly connected to the bottom of the screw rod 61. Thus, the motor 71 can be driven to rotate the worm 72, driving the screw rod 61 to rotate, enabling the bracket 2 to be lifted and lowered, so as to knock on walls of different heights.

[0024] The above are all the preferred embodiments of this application. The protection scope of this application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
