Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0026] As Figures 1 - 6 shown, a mortar strength detection device for a concrete wall includes a placement rack 1, and a fixing mechanism 2 is arranged on the placement rack 1;

[0027] The fixing mechanism 2 includes a moving frame 201. Two symmetrically arranged sliding grooves 202 are formed at the top of the moving frame 201. Two sliders 203 are slidably connected between the interiors of the two sliding grooves 202. A tee pipe 204 is installed on the inner wall of the bottom groove of the moving frame 201. Hollow blocks 205 are installed on both sides of the inner wall of the bottom groove of the moving frame 201. Cylindrical grooves 208 are formed on both sides of the inner wall of the bottom groove of the moving frame 201. Springs 206 are movably sleeved in the interiors of the two cylindrical grooves 208. Blocks 207 are movably sleeved in the interiors of the two cylindrical grooves 208. A double-headed traction rope 209 is installed between the opposite sides of the two blocks 207. A cylindrical block 210 is fixed at the converging end of the double-headed traction rope 209. The opposite ends of the two sliders 203 are adapted to each other. One end of the tee pipe 204 movably penetrates the inner wall of the bottom groove of the moving frame 201. The opposite ends of the two blocks 207 are respectively located inside the two springs 206. The opposite ends of the two springs 206 are respectively installed on the surfaces of the two blocks 207. The opposite ends of the two blocks 207 are respectively movably sleeved inside the two hollow blocks 205. The opposite ends of the two springs 206 are respectively installed on the opposite sides of the two hollow blocks 205. The opposite ends of the two blocks 207 respectively movably penetrate the inner walls of the two cylindrical grooves 208. The opposite ends of the two blocks 207 respectively movably penetrate the inner wall surfaces of each slider 203. The two diverging ends of the double-headed traction rope 209 are respectively movably sleeved inside the other two ends of the tee pipe 204. The converging end of the double-headed traction rope 209 is movably sleeved inside one end of the tee pipe 204. The surface of one end of the tee pipe 204 is in contact with the surface of the cylindrical block 210. The moving frame 201 is movably sleeved at the bottom end of the placing frame 1. Hand-tightening bolts 3 are threadedly penetrated through both sides of the moving frame 201. The threaded ends of each hand-tightening bolt 3 are abutted against the bottom surface of the placing frame 1. An intensity detector 4 is installed at the top of the placing frame 1. A standard block 5 is movably clamped at the moving end of the intensity detector 4. A mortar block 6 is adhesively connected to the bottom of the standard block 5. A test block 7 is adhesively connected to the bottom of the mortar block 6. The bottom of the test block 7 is in contact with the top of the moving frame 201. The test block 7 is located between the interiors of the two sliders 203, and the lower sides of the two sliders 203 are in contact with the top of the test block 7.

[0028] The achieved effect is that when it is necessary to detect the bonding strength of the mortar in the concrete wall, first, a mortar block 6 is made with the mortar to be detected at the middle position of the top of the test block 7. Then, the four hand-tightening bolts 3 are loosened, and then the moving frame 201 is lowered. After that, the cylindrical block 210 is used to pull the converging end of the double-headed traction rope 209. At this time, the moving converging end of the double-headed traction rope 209 will, with the cooperation of the three-way pipe 204, drive the two corresponding clamping blocks 207 to move towards each other between the inside of the corresponding hollow block 205 and the inside of the corresponding cylindrical groove 208. At the same time, the opposite ends of the two clamping blocks 207 will move out of the inside of the two sliders 203. At the same time, the two springs 206 will also be elastically deformed by compression. Then, the two sliders 203 are slid away from each other inside the two sliding grooves 202. After that, the bottom of the standard block 5 and the top of the mortar block 6 are fixed together using a high-strength adhesive such as epoxy resin. Finally, with the cooperation of the standard block 5, the mortar block 6 and the test block 7 are fixed together on the mobile end of the strength detector 4. When the standard block 5 completes the fixing operation on the mobile end of the strength detector 4, the moving frame 201 is moved until the bottom of the test block 7 contacts the top of the moving frame 201. Then, the four hand-tightening bolts 3 are tightened to fix the moving frame 201. Then, the two sliders 203 are both reset and moved back to their original positions. At this time, the lower sides of the two sliders 203 both contact the top of the test block 7. Then, the force applied to the cylindrical block 210 is released. At this time, the two clamping blocks 207 will respectively perform reset movement with the cooperation of the resilience of the corresponding springs 206, the cylindrical grooves 208, and the hollow blocks 205. When the two clamping blocks 207 are both reset to the initial positions, the two sliders 203 can be fixed, that is, the test block 7 can be fixed on the moving frame 201. Then, with the cooperation of the strength detector 4, the standard block 5, the test block 7, the fixing mechanism 2, and the placement rack 1, the bonding strength of the mortar block 6 can be detected.

[0029] Working principle: When it is necessary to detect the bonding strength of the mortar in the concrete wall, first make a mortar block 6 with the mortar to be detected at the middle position on the top of the test block 7. Then loosen the four hand-tightening bolts 3, and then lower the moving frame 201. After that, use the cylindrical block 210 to pull the converging end of the double-headed traction rope 209. At this time, the moving converging end of the double-headed traction rope 209 will drive the two corresponding clamping blocks 207 to move towards each other between the inside of the corresponding hollow block 205 and the inside of the corresponding cylindrical groove 208 under the cooperation of the three-way pipe 204. At the same time, the opposite ends of the two clamping blocks 207 will move away from the inside of the two sliders 203. At the same time, the two springs 206 will also be compressed elastically deformed. Then slide the two sliders 203 away from each other inside the two sliding grooves 202. Then use a high-strength adhesive such as epoxy resin to fix the bottom of the standard block 5 and the top of the mortar block 6 together. Finally, with the cooperation of the standard block 5, fix the mortar block 6 and the test block 7 together on the mobile end of the strength detector 4. When the standard block 5 completes the fixing operation on the mobile end of the strength detector 4, move the moving frame 201 until the bottom of the test block 7 touches the top of the moving frame 201. Then tighten the four hand-tightening bolts 3 to fix the moving frame 201. Then move the two sliders 203 back to their original positions. At this time, the lower sides of the two sliders 203 are in contact with the top of the test block 7. Then release the force applied to the cylindrical block 210. At this time, the two clamping blocks 207 will move back to their original positions respectively under the cooperation of the resilience of the corresponding springs 206, the cylindrical grooves 208 and the hollow blocks 205. When the two clamping blocks 207 are both reset to their initial positions, the two sliders 203 can be fixed, that is, the test block 7 can be fixed on the moving frame 201. Then, with the cooperation of the strength detector 4, the standard block 5, the test block 7, the fixing mechanism 2 and the placing rack 1, the bonding strength of the mortar block 6 can be detected.

[0030] The moving frame 201 is movably sleeved at the bottom end of the placing rack 1, that is, the four support legs of the placing rack 1 are respectively movably sleeved inside the four through holes at the top of the moving frame 201;

[0031] The connection between the bottom of the mortar block 6 and the top of the test block 7 is that the mortar (prepared dry-mixed cement wall mortar slurry) solidifies and bonds on the test block 7, and between the bottom of the standard block 5 and the top of the mortar block 6 is through a high-strength adhesive such as epoxy resin;

[0032] The centers of the two hollow blocks 205 and the centers of the other two end ports of the three-way pipe 204 are on the same horizontal line;

[0033] The strength detector 4 is a professional device for detecting the bonding strength of the mortar in the concrete wall, evaluating the bonding quality of the concrete mortar, and is usually composed of the following parts:

[0034] Electric drive system: Provides a power source to drive the operation of the detection components.
