Description

Technical Field

[0001] The present invention relates to the technical field of building detection, in particular to an all-round detection device for a building main structure. Background Art

[0002] Buildings are man-made assets that fall under the category of fixed assets, including two major categories: houses and structures. Houses refer to engineering buildings for people to live, work, study, produce, operate, entertain, store items, and conduct other social activities. The main body of a building refers to the structural structure of the building entity, including roofs, floors, beams, columns, supports, walls, connection points, and foundations. When inspecting the main body of a building, a rebound tester is needed to test the quality of the concrete of the main body to ensure the quality and safety of the building.

[0003] However, the traditional rebound hammer used for testing is not convenient to keep it perpendicular to the wall during use. When it is skewed, it is easy to affect the detection effect. At the same time, the rebound hammer has a cylindrical structure, which is inconvenient to hold during operation and can easily slip and be damaged if not careful. In addition, the wall needs to be marked and positioned during testing. Currently, this operation is done manually with a water pen and a ruler, which is very inconvenient to use, time-consuming and labor-intensive, and reduces the efficiency of testing.

[0014] The beneficial effects of the present invention are:

[0015] (1) The present invention provides an all-round detection device for the main structure of a building. The installation of a positioning mechanism is conducive to keeping the rebound hammer perpendicular to the wall surface, which is convenient for accurate measurement. The action of the limiting mechanism is conducive to preventing the positioning mechanism from slipping, that is, the action of the connecting sleeve is conducive to the installation of the rebound hammer, and it is convenient for subsequent free disassembly. The four sliding rods can be connected by installing the four fixing rods and the connecting sleeve, and the sliding rods are connected to the connecting sleeve and the inside of the fixing rods by sliding under the action of the telescopic spring. The installation of the fixing sleeve makes the four The four sliding rods can be connected and fixed to achieve synchronous sliding of the four sliding rods.

The limit block is engaged with the inside of the limit groove under the action of the interference spring, which is conducive to limiting the sliding rod and preventing the sliding rod and the fixed rod from slipping and separating. At the same time, since the limit block and the limit groove are trapezoidal structures, when the sliding rod slides in the opposite direction, one side of the limit block is contacted and contracted by the side wall of the limit groove, thereby facilitating the sliding and contraction of the sliding rod.

[0016] (2) The all-round detection device for the main structure of a building described in the present invention is conducive to the positioning mechanism being able to be rotated and folded for storage through the cooperation of the storage mechanism and the positioning mechanism, so that it is convenient to carry, more convenient to operate, and saves space.

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] like Figures 1-8 As shown, the present invention provides an all-round detection device for a building main structure, comprising a rebound hammer 1, a positioning mechanism 2 being installed on the rebound hammer 1, a storage mechanism 3 being installed on the positioning mechanism 2, a limiting mechanism 4 being installed on the positioning mechanism 2, a holding mechanism 5 being installed on the rebound hammer 1, a locking mechanism 6 being installed on the positioning mechanism 2, and a marking mechanism 7 being installed on the rebound hammer 1.

[0031] Specifically, the positioning mechanism 2 includes a connecting sleeve 201, one end of the rebound instrument 1 is snap-connected with the connecting sleeve 201, the inner side of the connecting sleeve 201 is a hexagonal structure, one side of the connecting sleeve 201 is fixedly connected to four annularly distributed fixing rods 202, and the other side of the connecting sleeve 201 is vertically connected to four annularly distributed sliding rods 205, one end of the sliding rod 205 is slidably connected to the inside of the connecting sleeve 201, and one end of the sliding rod 205 is slidably connected to the inside of the fixing rod 202 through a telescopic spring 206.

The fixing sleeve 203 is used to install the four sliding rods 205, so that the four sliding rods 205 can slide synchronously. The four vertical support rods 204 are used to facilitate the fit with the wall, so that the rebound tester 1 can remain perpendicular to the wall, thereby pressing the rebound tester 1, and the sliding rod 205 slides with the fixing rod 202 to realize the detection of the interference between the rebound tester 1 and the wall.

[0032] Specifically, the limiting mechanism 4 includes a limiting block 401, and a symmetrical limiting block 401 is installed inside one end of the four sliding rods 205. The limiting block 401 is slidably connected to the inside of the sliding rod 205 through a conflicting spring 402. A symmetrical limiting groove 403 is provided on the inner side of one end of the four fixed rods 202. The limiting groove 403 and the limiting block 401 are both trapezoidal structures. One end of the limiting block 401 extends to the outside of the sliding rod 205 and conflicts with the inside of the limiting groove 403. Under the action of the resistance spring 402, the limit block 401 is engaged with the inside of the limit groove 403, which is beneficial to limiting the slide rod 205 and preventing the slide rod 205 from slipping and separating from the fixed rod 202. At the same time, since the limit block 401 and the limit groove 403 are trapezoidal structures, when the slide rod 205 slides in the opposite direction, one side of the limit block 401 is resisted and contracted by the side wall of the limit groove 403, thereby facilitating the sliding and contraction of the slide rod 205.

[0033] Specifically, the storage mechanism 3 includes a rotation groove 302, and the four slide bars 205 are respectively provided with a rotation groove 302, one end of the rotation groove 302 extends to the outside of the slide bar 205, and a fixed shaft 303 is provided inside one end of the rotation groove 302. Both ends of the fixed shaft 303 are fixedly connected to the inside of the slide bar 205, and a movable groove 306 is provided on the support rod 204. The support rod 204 is slidably connected to the fixed shaft 303 through the movable groove 306. A stopper 301 is installed on the side wall of one end of the slide bar 205, and the side wall of the support rod 204 conflicts with the stopper 301. The cooperation is conducive to connecting the support rod 204 and enabling the support rod 204 to rotate on the slide rod 205. The support rod 204 is rotated to be level with the slide rod 205 under the action of the rotating groove 302, and then the support rod 204 is conveniently inserted into the slide rod 205 under the action of the movable groove 306, so as to facilitate the storage of the support rod 204. After pulling out the support rod 204, the support rod 204 is rotated to be perpendicular to the slide rod 205, which is convenient for positioning work, and the support rod 204 is stabilized by the action of the stop block 301.

[0034] Specifically, a rubber block 304 is installed on the inner side of the bottom of one end of the four sliding rods 205, and one end of the rubber block 304 is slidably connected to the inside of the sliding rod 205 through a compression spring 305. The top of the rubber block 304 extends to the inside of the rotating groove 302. The top of the rubber block 304 is an arc-shaped structure. Under the action of the compression spring 305, the rubber block 304 has elasticity, which is conducive to the top of the rubber block 304 to contact one end of the support rod 204, making the support rod 204 stable and not easy to loosen. After the support rod 204 is stored in the sliding rod 205, the rubber block 304 contacts the support rod 204, so that the support rod 204 will not slide out easily, thereby playing a protective role.

[0035] Specifically, the holding mechanism 5 includes a connecting plate 501, and the connecting plate 501 is engaged with the bottom of the connecting sleeve 201. One end of the connecting plate 501 is in contact with the side wall of the rebound tester 1. A handle 502 is installed at the bottom of the connecting plate 501. The handle 502 is a "concave" shaped structure. The engagement of the connecting plate 501 with the inner side of the bottom of the connecting sleeve 201 is conducive to subsequent disassembly and assembly. The installation of the handle 502 makes it convenient to hold the connecting plate 501, thereby realizing the taking out of the rebound tester 1 when working, making the operation more convenient and smooth.

[0036] The cam 503 is screwed to the bottom of the cam 501 and the cam 503 is screwed to the bottom of the cam 501.

[0037] Specifically, the locking mechanism 6 includes a push rod 601, and a push rod 601 is installed on the inner side of the bottom of the connecting sleeve 201. The push rod 601 is longitudinally slidably connected to the inner side of the bottom of the connecting sleeve 201 by an extrusion spring 602. The top of the push rod 601 extends to the outside of the connecting sleeve 201 and is engaged with the inner side of the bottom of the rebound hammer 1. A protrusion 603 is installed on the bottom of the push rod 601, and the bottom of the protrusion 603 extends to the outer side of the bottom of the connecting sleeve 201 and contacts the connecting plate 501. The bottom of the protrusion 603 is a hemispherical structure. After being installed through the connecting plate 501, the connecting plate 501 contacts the bottom of the protrusion 603. The contact of the protrusion 603 drives the push rod 601 to slide, and the push rod 601 is freed from the action of the extrusion spring 602 and slides into the inner side of the rebound hammer 1, thereby limiting the rebound hammer 1 and making the connecting sleeve 201 and the rebound hammer 1 firmly and stably installed.

[0038] Specifically, the marking mechanism 7 includes a sleeve 701, a partition 702 is installed inside the sleeve 701, the sleeve 701 is fitted with the outer side of one end of the rebound test hammer 1, and a rubber plug 703 is threadedly connected to one end of the sleeve 701. The rubber plug 703 is a cylindrical "T"-shaped structure, and the diameter of one end of the rubber plug 703 is larger than the diameter of the sleeve 701. A fixed shell 704 is installed at the other end of the rubber plug 703, and a printing surface 705 is installed on the fixed shell 704. The action of the sleeve 701 is conducive to the installation with the rebound test hammer 1 and the connection of the rubber plug 703 is convenient. The threaded connection between the rubber plug 703 and the sleeve 701 is conducive to comfortable pushing of the rebound test hammer 1. The threaded connection facilitates the subsequent disassembly and maintenance of the rubber plug 703 and the addition of ink to the printing surface 705. At the same time, under the action of the fixed shell 704 and the printing surface 705, it is convenient to mark the wall, which facilitates subsequent accurate detection work.

[0039] When the present invention is used, first, the action of the ferrule 701 facilitates the installation of the rebound hammer 1 and facilitates the connection of the rubber plug 703. The threaded connection between the rubber plug 703 and the ferrule 701 facilitates the comfortable pushing of the rebound hammer 1. The threaded connection facilitates the subsequent disassembly and maintenance of the rubber plug 703 and the convenient addition of ink to the printing surface 705. At the same time, the action of the fixed shell 704 and the printing surface 705 facilitates the marking of the wall, facilitating the subsequent accurate detection work.The connecting sleeve 201 is conducive to the engagement and installation with the rebound tester 1, and is convenient for subsequent free disassembly. The four fixing rods 202 are installed with the connecting sleeve 201, so that the four sliding rods 205 can be connected, and the sliding rod 205 is slidably connected with the connecting sleeve 201 and the fixing rod 202 under the action of the telescopic spring 206. The four sliding rods 205 are connected and fixed by the installation of the fixing sleeve 203, so that the four sliding rods 205 can slide synchronously. The four vertical support rods 204 are conducive to fitting with the wall, so that the rebound tester 1 can be kept perpendicular to the wall, thereby pressing the rebound tester 1, and the sliding rod 205 slides with the fixing rod 202 to realize the collision detection between the rebound tester 1 and the wall. The limit rod 205 is connected and fixed by the contact spring 402. The block 401 is engaged with the inner part of the limit groove 403, which is conducive to limiting the position of the slide bar 205, so that the slide bar 205 and the fixed rod 202 will not slip and separate. At the same time, since the limit block 401 and the limit groove 403 are trapezoidal structures, when the slide bar 205 slides in the opposite direction, one side of the limit block 401 is abutted and contracted by the side wall of the limit groove 403, thereby facilitating the slide bar 205 to slide and contract. Through the cooperation of the movable groove 306 and the fixed shaft 303, it is conducive to connecting the support rod 204 and enabling the support rod 204 to rotate on the slide bar 205. Under the action of the rotating groove 302, the support rod 204 is rotated to be level with the slide bar 205, and then the support rod 204 is conveniently inserted into the slide bar 205 under the action of the movable groove 306, thereby facilitating the support rod 204. When the support rod 204 is stored in the slide bar 205, the rubber block 304 contacts the support rod 204, so that the support rod 204 will not slide out easily, which plays a protective role. The engagement of the connecting plate 501 with the inner side of the bottom of the connecting sleeve 201 is convenient for subsequent disassembly and assembly. The installation of the handle 502 makes it easy to hold the connecting plate 501, thereby achieving The removal of the rebound hammer 1 during operation makes the operation more convenient and smooth. After the connecting plate 501 is engaged with the connecting sleeve 201, the screw 504 is rotated. The screw 504 drives the latch 503 to slide inside the connecting plate 501 under the action of the thread, so that the latch 503 is engaged and separated from the latch groove 505, thereby facilitating the limited engagement between the connecting plate 501 and the connecting sleeve 201 and facilitating subsequent disassembly. The operation is more convenient. After the connecting plate 501 is installed, the connecting plate 501 contacts the bottom of the protrusion 603. The protrusion 603 is contacted and drives the push rod 601 to slide. The push rod 601 is freed from the action of the extrusion spring 602 and slides into the inner side of the rebound hammer 1, thereby limiting the engagement of the rebound hammer 1 and making the connection sleeve 201 and the rebound hammer 1 firmly and stably installed.
