Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a construction engineering hollowing detection device. Background Art

[0002] In construction projects, it is necessary to lay tiles, stones, special-shaped blocks, etc. on the outside of the structural layer. Hollowing may occur between the wall of the house and the structural layer due to loose adhesion and bonding. During inspection, use a hollowing hammer or hard object to tap the plaster layer and leveling layer. If a thudding sound is heard, it is a hollowing sound. If there are many hollow areas on the wall that do not meet the standards, there is a certain safety hazard.

[0003] Current hollowing detection devices mostly use hollowing hammers for knocking. However, in large-scale projects, due to the large wall area and heavy workload, if manual knocking is used continuously, the workers will be overworked. In addition, the frequency of manual knocking cannot be maintained at a fast frequency, which may affect the efficiency of wall hollowing detection. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a construction engineering hollowing detection device that can overcome the above problems or at least partially solve the above problems.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The hollowing detection device for construction projects includes: a detection hammer, and also includes: a hand-held rod fixedly arranged at the lower end of the detection hammer; an electric telescopic rod arranged in the detection hammer; a limit ring symmetrically fixedly connected in the detection hammer, and the limit ring is used to limit the electric telescopic rod; a striking block fixedly arranged at the output end of the electric telescopic rod; a fixing sleeve fixedly arranged at one end of the detection hammer close to the striking block; a first hammer head threadedly connected in the fixing sleeve; and a controller fixedly arranged at one end of the electric telescopic rod away from the striking block.

[0007] Preferably, the lower end of the hand-held rod is detachably connected to an extension rod.

[0008] In order to reduce the contact area between the first hammer head and the wall surface, further, a plurality of contact balls are fixedly connected to the first hammer head.

[0009] Preferably, the end of the detection hammer away from the first hammer head is threadedly connected to the second hammer head, and the first hammer head matches the second hammer head.

[0010] In order to facilitate the control of the electric telescopic rod, a first button and a second button are further provided on the handheld rod. The first button is used to control the opening and closing of the electric telescopic rod, and the second button is used to control the frequency of the reciprocating movement of the output end of the electric telescopic rod.

[0011] In order to facilitate better sound extraction, the detection hammer is further provided with multiple groups of through holes.

[0012] Compared with the prior art, the present invention provides a hollowing detection device for construction projects, which has the following beneficial effects:

[0013] 1. The hollowing detection device for construction projects controls the opening of the electric telescopic rod through a first button, and controls the electric telescopic rod through a controller to drive the striking block to move back and forth and strike the fixed sleeve at a specified frequency. The staff puts the first hammer head in contact with the wall and keeps the first hammer head in contact with the wall at all times. By adjusting the contact position of the first hammer head with the wall, different positions of the wall are detected. The striking block directly strikes the fixed sleeve, and the fixed sleeve is connected to the first hammer head. Therefore, whether the wall is hollow can be directly judged by the sound emitted by the fixed sleeve, which is convenient for judgment and does not require multiple knocks, thereby effectively preventing the staff from being overworked and effectively improving the efficiency of hollowing detection.

[0014] 2. The hollowing detection device for construction projects contacts the wall surface through multiple contact balls, which can effectively reduce the friction between the first hammer head and the wall surface while detecting multiple points, making it easy to replace the position of the first hammer head.

[0015] 3. The hollowing detection device for construction projects has multiple through holes on the detection hammer to facilitate the transmission of the sound of the striking block hitting the fixed sleeve, effectively preventing the muffled sound of the detection hammer with a cavity from affecting the judgment of the hollowing state.

[0016] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model does not require multiple knocks, thereby effectively preventing the staff from being overworked, and at the same time can effectively improve the efficiency of hollow drum detection.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1: Reference Figure 1-Figure 3 The hollowing detection device for construction projects includes: a detection hammer 1, and also includes: a hand-held rod 2, which is fixedly arranged at the lower end of the detection hammer 1; an electric telescopic rod 101, which is arranged in the detection hammer 1; a limiting ring 106, which is symmetrically fixedly connected in the detection hammer 1, and the limiting ring 106 is used to limit the electric telescopic rod 101; a striking block 102, which is fixedly arranged at the output end of the electric telescopic rod 101; a fixing sleeve 103, which is fixedly arranged at one end of the detection hammer 1 close to the striking block 102; a first hammer head 104, which is threadedly connected in the fixing sleeve 103; and a controller 107, which is fixedly arranged at one end of the electric telescopic rod 101 away from the striking block 102.

[0023] The lower end of the handheld rod 2 is detachably connected to an extension rod 201 .

[0024] The handheld rod 2 is provided with a first button 202 and a second button 203 . The first button 202 is used to control the opening and closing of the electric telescopic rod 101 , and the second button 203 is used to control the frequency of the reciprocating movement of the output end of the electric telescopic rod 101 .

[0025] In construction projects, when detecting hollowing of a wall, it is determined whether to install an extension rod 201 based on the length. Without installing the extension rod 201, the handheld rod 2 is held in the hand, and the electric telescopic rod 101 is controlled to be turned on by the first button 202. The electric telescopic rod 101 is controlled by the controller 107 to drive the striking block 102 to move back and forth and strike the fixed sleeve 103 at a specified frequency. The staff brings the first hammer head 104 into contact with the wall and keeps the first hammer head 104 in contact with the wall at all times. By adjusting the contact position of the first hammer head 104 with the wall, different positions of the wall are detected. The striking block 102 directly strikes the fixed sleeve 103, and the fixed sleeve 103 is connected to the first hammer head 104. Therefore, whether the wall is hollow can be directly judged by the sound emitted by the fixed sleeve 103, which is convenient for judgment and does not require multiple knocks, thereby effectively preventing the staff from being overworked and effectively improving the efficiency of hollowing detection.

[0026] Example 2: Reference Figure 1-Figure 3 The hollowing detection device for construction engineering is basically the same as that of Example 1. Furthermore, a plurality of contact balls 105 are fixedly connected to the first hammer head 104.

[0027] When testing a rough artistic stone wall, multiple contact balls 105 contact the wall, which can effectively reduce the friction between the first hammer head 104 and the wall while testing multiple points, making it easier to replace the position of the first hammer head 104.

[0028] One end of the detection hammer 1 away from the first hammer head 104 is threadedly connected to the second hammer head 109 , and the first hammer head 104 matches the second hammer head 109 .

[0029] When the position cannot be accurately determined, the wall surface is manually struck vigorously to make the second hammer head 109 contact the wall surface, thereby effectively improving the accuracy of the detection.

[0030] The detection hammer 1 is provided with a plurality of through holes 108 .

[0031] By providing a plurality of through holes 108 on the detection hammer 1, the sound of the striking block 102 striking the fixing sleeve 103 can be easily transmitted, thereby effectively preventing the detection hammer 1 with a cavity from producing muffled sound that affects the judgment of the hollow state.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
