Description

Technical Field

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

[0002] The thickness of floor slabs in modern buildings plays a very important role in the safety of engineering structures. The increase or decrease of the floor slab thickness will cause the change of the center deflection of the floor slab. The thickness of the floor slab will affect a series of problems such as sound insulation, heat insulation, vibration, and waterproofing of the house. Therefore, the floor slab thickness is one of the must-check items in engineering quality inspection.

[0003] For example, the floor thickness detection device disclosed in the authorization announcement number CN210374975U can quickly measure the thickness of building floors.

[0004] However, the problem that the device needs to be held manually when in use is not solved. Holding the device for a long time puts a heavy burden on the staff, and the staff may shake the transmitter probe when holding it, resulting in inaccurate data.

[0005] For this reason, we propose a floor slab thickness detection device for construction projects. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the utility model provides a floor thickness detection device for construction projects. The base is temporarily fixed to the bottom surface of the floor by the adhesive patch on the upper surface of the fixing base. At this time, there is no need to hold the base with hands and the positioning is completed. With both hands freed, screws can be taken out and screwed into the floor through the positioning bolt holes of the fixing base to ensure that the base is firmly located on the bottom surface of the floor and will not fall off. The transmitter probe does not need to be held by the staff, which avoids the shaking of the transmitter probe during measurement and improves the accuracy of the floor thickness measurement.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A floor thickness detection device for construction projects, comprising a transmitter probe and a corresponding receiver probe, wherein the transmitter probe is located below the floor slab and the receiver probe is located above the floor slab. The device also comprises a base, wherein a lifting hole is provided at the center of the upper surface of the base, and a floating block is provided in the lifting hole so as to slide up and down. The transmitter probe is embedded in the upper surface of the floating block, and the upper surface of the floating block is higher than the upper surface of the base.

[0009] The outer walls on both sides of the base are symmetrically connected with fixing seats, the upper surface of the fixing seats is higher than the upper surface of the base and lower than the upper surface of the floating block, the upper surface of the fixing seats is covered with an adhesive patch, and a positioning bolt hole is longitudinally opened through the center of the lower surface of the fixing seat.

[0010] Preferably, a handle is connected to the outer side surface of the floating block.

[0011] Preferably, a protective pad is provided on the upper surface of the floating block, the top surface of the protective pad is higher than the top surface of the transmitter probe, and the protective pad is distributed around the transmitter probe.

[0012] Preferably, the bottom surface of the base is located on both sides of the lifting hole and guide rods are provided in parallel. The bottom of the floating block penetrates the lifting hole and is located below the bottom surface of the base. The bottom of the floating block is detachably connected to a connecting frame. The outer walls on both sides of the connecting frame are connected with sliding sleeves. The sliding sleeves are sleeved on the outer surface of the guide rods and slide up and down with each other.

[0013] Preferably, the bottom end of the guide rod is connected to a limiting plate, a spring is wound around the outer surface of the lower end of the guide rod, the top end of the spring abuts against the bottom surface of the sleeve, and the bottom end of the spring abuts against the top surface of the limiting plate.

[0014] Preferably, the limiting plate and the guide rod are detachably connected, and the top surface of the limiting plate and the bottom surface of the guide rod are threadedly connected.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The base is temporarily fixed to the bottom surface of the floor slab with the adhesive patch on the upper surface of the fixing base. At this time, there is no need to hold the base and the positioning is completed. With both hands free, screws can be taken out and screwed into the floor slab through the positioning bolt holes of the fixing base to ensure that the base is firmly located on the bottom surface of the floor slab and will not fall off. The transmitter probe does not need to be held by the staff, which avoids the shaking of the transmitter probe during measurement and improves the accuracy of the floor slab thickness measurement;

[0017] The upper surface of the floating block is located at the highest surface, so it will contact the bottom surface of the floor before the fixed seat. At the same time, the floating block slides down along the lifting hole of the base, which ensures that the upper surface of the floating block is in contact with the bottom surface of the floor, that is, there is no gap between the transmitter probe embedded in the upper surface of the floating block and the bottom surface of the floor, which improves the accuracy of the floor thickness measurement without causing extrusion damage between the transmitter probe and the bottom surface of the floor.

The outer walls on both sides of the base 2 are symmetrically connected with a fixing seat 3, the upper surface of the fixing seat 3 is higher than the upper surface of the base 2 and lower than the upper surface of the floating block 1.
