[0023] Please see Figure 1-6 One embodiment provided by this utility model:

[0024] A surface flatness testing device for building construction includes a base 1, an adjusting sleeve 2, and a testing platform 3. A support column 11 is fixedly connected to the surface of the base 1. A limit plate 12 is threadedly connected to the end of the support column 11 away from the base 1. The adjusting sleeve 2 is sleeved on the outer surface of the support column 11. A support frame 21 is fixedly connected to the outer surface of the adjusting sleeve 2. The testing platform 3 is fixedly connected to the support frame 21. Connecting sleeves 4 are fixedly connected to both ends of the adjusting sleeve 2. A control sleeve 5 is sleeved on the outer surface of the connecting sleeve 4. A connecting chamber 6 is fixedly connected to the surface of the testing platform 3. The inner side of the connecting chamber 6... A support spring 62 is fixedly connected, a movable frame 63 is fixedly connected to the surface of the support spring 62, a pressure plate 61 is movably connected to the surface of the movable frame 63, a mounting base 7 is fixedly connected to the surface of both the pressure plate 61 and the surface of the detection platform 3, a spirit level 71 is fitted onto the surface of the mounting base 7, a telescopic rod 8 is connected through the surface of the detection platform 3, and a telescopic spring 81 is sleeved on the outer surface of the telescopic rod 8. Through the connection of the base 1 and the support column 11, and under the connection of the support column 11 and the adjusting sleeve 2, the action of the connecting sleeve 4 and the control sleeve 5 achieves the effect of supporting and adjusting the position of the detection platform 3.

[0025] Furthermore, the adjusting sleeve 2 is fixedly connected to the detection platform 3 via the support frame 21, and the detection platform 3 is slidably connected to the support column 11 via the adjusting sleeve 2. The limiting plate 12 is in the shape of a disc and is connected to the end of the support column 11 away from the base 1. Through the connection between the adjusting sleeve 2 and the support frame 21, the adjusting sleeve 2 supports the detection platform 3 under the action of the support frame 21. Under the connection between the adjusting sleeve 2 and the support column 11, the position of the detection platform 3 can be adjusted.

[0026] Furthermore, the connecting sleeve 4 consists of two parts. One part of the connecting sleeve 4 is cylindrical, and the outer surface of the other part of the connecting sleeve 4 is inclined. The inner wall of the connecting sleeve 4 abuts against the support column 11. Through the connection of the connecting sleeve 4 and the adjusting sleeve 2, under the action of the connecting sleeve 4, and through the connection of the control sleeve 5 and the connecting sleeve 4, the abutting support operation of the connection between the connecting sleeve 4 and the support column 11 is realized, thereby achieving the support and control effect of the adjusting sleeve 2 on the support column 11.

[0027] Furthermore, the control sleeve 5 consists of two parts. One part of the control sleeve 5 is hexagonal and threadedly connected to the connecting sleeve 4. The other part of the control sleeve 5 is circular and abuts against the outer surface of the connecting sleeve 4. Through the abutting contact between the control sleeve 5 and the connecting sleeve 4, and the abutting contact between the connecting sleeve 4 and the support column 11, the support control effect on the position of the adjusting sleeve 2 on the support column 11 is achieved.

[0028] Furthermore, the two ends of the pressure plate 61 abut against the telescopic rod 8. The pressure plate 61 is rotatably connected to the detection platform 3 through the movable frame 63. The movable frame 63 is elastically slidably connected to the connecting chamber 6 through the support spring 62. Through the connection between the connecting chamber 6 and the support spring 62, and under the connection between the support spring 62 and the movable frame 63, the elastic sliding effect of the pressure plate 61's working position is realized, which facilitates the use of the pressure plate 61 to cooperate with the change of the working position of the telescopic rod 8 on the detection platform 3.

[0029] Furthermore, the surface of the mounting base 7 is provided with a placement groove 72, the inner wall of the placement groove 72 is fixedly connected with a backing plate 74, and the surface of the backing plate 74 is fixedly connected with a connecting spring 73.

[0030] Furthermore, the abutment plate 74 is elastically connected to the placement groove 72 via the connecting spring 73. The abutment plate 74 and the spirit level 71 are in contact at both ends. The telescopic rod 8 is elastically slidably connected to the detection platform 3 via the telescopic spring 81. With the connection between the connecting spring 73 and the abutment plate 74, the abutment plate 74 provides support for the spirit level 71 on the mounting base 7. By observing the spirit level 71, the consistency of the telescopic rod 8's working length on the detection platform 3 can be directly observed, thus achieving the detection effect of road surface smoothness.

[0031] Working principle: When testing the smoothness of the road surface, the placement base 1 is placed in the corresponding position. With the placement base 1 and the support column 11 connected, the position of the testing platform 3 is changed through the connection of the adjusting sleeve 2 and the support column 11. With the connection of the testing platform 3 and the telescopic rod 8, the telescopic rod 8 contacts the ground. At this time, the position of the telescopic rod 8 on the testing platform 3 changes. With the contact between the pressure plate 61 and the telescopic rod 8, the pressure plate 61 and the mounting base 7 are connected. Under the action of the mounting base 7 and the spirit level 71, by observing the spirit level 71, it is determined whether the working length of the telescopic rod 8 on the testing platform 3 is consistent, thus completing the test of the road surface smoothness.
