Description

Technical Field

[0001] The utility model relates to the technical field of building construction detection, in particular to a cast-in-place slab thickness detection machine at a construction site. Background Art

[0002] Cast-in-place slabs, also known as cast-in-place floor slabs, refer to slabs formed by directly pouring concrete after installing steel bars on the formwork according to design requirements at the construction site. During the architectural design stage, the thickness of the slab will be determined based on factors such as the function and load of the building. Therefore, it is necessary to measure the thickness of the cast-in-place slab to ensure that the construction results are consistent with the design requirements and to ensure the overall quality and safety of the building.

[0003] However, the current thickness detection device has a relatively simple structure, and when in use, the detection device is usually unable to stably support on the cast-in-place slab, and requires the assistance of other personnel when taking readings, which is time-consuming and labor-intensive, and reduces the efficiency of the detection.

[0004] For example, the publication number "CN219956365U" provides a device for detecting the thickness of cast-in-place concrete slabs. When the device is in use, three support rods can provide stable support, eliminating the need for workers to find the vertical direction. After the worker pushes the conical head to contact the cast-in-place slab, the thickness of the cast-in-place slab can be read through the ruler. The entire detection process can be completed by only one worker. Compared with traditional cast-in-place slab thickness detectors, the utility model saves manpower and improves the practicability of the detector.

[0005] However, the above device still has the following problems during implementation:

[0006] The device is large in size, and it is troublesome to move and store it after use. When the device is in use, the top plate is pressed down to move the sliding block and the support rod downward and insert them into the cast-in-place slab for measurement. However, during the pressing process, the downward force acts on the bottom plate, causing the bottom plate to move downward at the same time, causing the bottom plate to sink into the cast-in-place slab, resulting in errors in the measurement results. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] For example, see Figure 1-5 A cast-in-place slab thickness detection machine at a construction site comprises a sliding component 1 and a measuring component 3 arranged on the sliding component 1. The sliding component 1 comprises a sliding rod 11, on which a scale line is arranged, a fixing plate 12 is installed on the top of the sliding rod 11, and handles 13 are also installed on both sides of the fixing plate 12. An adjusting component 2 is also arranged on one side of the sliding rod 11. A sliding sleeve 14 is slidably connected to the sliding component 1, and the measuring component 3 is connected to the sliding rod 11 through the sliding sleeve 14. Two auxiliary supporting components 4 that are fixed to the auxiliary sliding component 1 are also symmetrically arranged at the bottom of the sliding component 1;

[0029] When the device is needed, first place the bottom of the sliding component 1 and the auxiliary support component 4 on the top of the cast-in-place slab, adjust the position of the measuring component 3 by adjusting the component 2, so that the bottom of the measuring component 3 contacts the top of the cast-in-place slab, and the top of the measuring component 3 matches the initial position of the scale line on the sliding rod 11, adjust the adjusting component 2, and move the measuring component 3 downward to insert into the cast-in-place slab. When the bottom of the measuring component 3 contacts the bottom of the cast-in-place slab, stop adjusting the adjusting component 2, and read the thickness of the cast-in-place slab through the scale line on the sliding rod 11;

[0030] When in use, the handles 13 provided on both sides of the fixing plate 12 can be used to conveniently move the entire device for easy use.

[0031] For example 2, please refer to Figure 1 , Figure 2 and Figure 3The adjusting assembly 2 includes a rotating screw 21, which is arranged on one side of the sliding rod 11. The bottom of the rotating screw 21 is rotatably connected to a connecting plate 24. The connecting plate 24 is fixed to the sliding rod 11 on one side of the sliding rod 11. The top of the rotating screw 21 is rotatably connected to the fixing plate 12, and the top of the rotating screw 21 passes through and extends out of the top of the fixing plate 12. The extended end of the rotating screw 21 is fixedly connected to a knob 22. The rotating screw 21 is also threadedly connected to a moving ring 23. The moving ring 23 is close to the sliding rod. One end of the rod 11 is fixed to the sliding sleeve 14 on the sliding rod 11, and the measuring assembly 3 includes a measuring plug rod 31, a folding groove 34 is provided at the top of the measuring plug rod 31, a connecting rod 32 is hinged on the folding groove 34, a rotating groove 33 is provided at one end of the connecting rod 32 away from the measuring plug rod 31, and the rotating groove 33 is rotatably connected to the sliding sleeve 14, the opening length of the folding groove 34 is consistent with the length of the connecting rod 32, and a limiting plate 35 is installed on the top of the connecting rod 32, and both ends of the limiting plate 35 are in contact with the top of the measuring plug rod 31;

[0032] When the cam 31 is in the closed position, the lever 32 is in the closed position and the lever 32 is in the closed position.

[0033] After adjustment, turn the knob 22 so that the knob 22 drives the rotating screw 21 to rotate. When the rotating screw 21 rotates, the moving ring 23 on the rotating screw 21 starts to slide up and down along the rotating screw 21, and at the same time drives the sliding sleeve 14 to slide up and down on the sliding rod 11, so that the measuring plug rod 31 moves up and down, and the sliding sleeve 14 is moved to the initial position of the scale line on the sliding rod 11, so that the bottom of the measuring plug rod 31 is at the same level as the bottom of the sliding rod 11, and the sliding rod 11 is placed on the top of the cast-in-place slab, and the knob 22 is turned again, so that the knob 22 drives the moving ring 23 and the sliding sleeve 14 to move downward, so that the measuring plug rod 31 moves downward and is inserted into the cast-in-place slab until the bottom of the measuring plug rod 31 contacts the bottom of the cast-in-place slab. At this time, the position of the sliding sleeve 14 on the scale line of the sliding rod 11 can be observed to obtain the thickness of the cast-in-place slab.

[0034] When use is completed, lift the measuring rod 31 upwards, rotate the top of the measuring rod 31 along one end of the connecting rod 32, rotate the other end of the connecting rod 32 along the sliding sleeve 14, fold the connecting rod 32 in the folding groove 34, and then fold the measuring rod 31.

[0035] For example 3, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The auxiliary support assembly 4 includes a support plate 41, and a card slot 42 is provided at one end of the support plate 41 away from the sliding rod 11. Two buckles 15 are symmetrically installed on the sliding rod 11, and the two buckles 15 are respectively adapted to the card slots 42 on the two support plates 41. The other end of the support plate 41 is fixedly connected with a rotating shaft 43. Two connecting blocks 5 are symmetrically installed on the surface of the sliding assembly 1 near the bottom. The rotating shafts 43 on the two support plates 41 are respectively rotatably connected to the adjacent connecting blocks 5. Each connecting block 5 is provided with a sliding groove 51, and an abutting block 52 is slidably connected in the sliding groove 51. The bottom of the abutting block 52 abuts against the top of the rotating shaft 43. A return spring 53 is also provided in the sliding groove 51. One end of the return spring 53 is fixedly connected to the inner wall of the sliding groove 51, and the other end is fixedly connected to the abutting block 52. A pull plate 54 is also installed on the top of the abutting block 52, and the pull plate 54 slides on the sliding groove 51.

[0036] Before use, rotate the support plate 41 so that the rotating shaft 43 on the support plate 41 rotates along the connecting block 5, so that the card slot 42 is disengaged from the buckle 15, until the bottom of the support plate 41 is parallel to the bottom of the connecting block 5, so that the two support plates 41 are unfolded, and the contact area between the whole device and the top of the cast-in-place slab is increased, so that the whole device is more stable;

[0037] When the support plate 41 and the rotating shaft 43 rotate along the connecting block 5, the side wall of the rotating shaft 43 squeezes the abutting block 52, so that the abutting block 52 shrinks in the sliding groove 51. When the support plate 41, the rotating shaft 43 and the connecting block 5 are parallel, the abutting block 52 is no longer pushed by the rotating shaft 43, and pops outward under the action of the return spring 53, and abuts against the top of the rotating shaft 43, limiting the rotating shaft 43.

[0038] When the auxiliary support assembly 4 needs to be folded up after use, the pull plate 54 is pulled, so that the pull plate 54 drives the abutment block 52 to slide into the sliding groove 51, so that the rotating shaft 43 is no longer limited by the abutment block 52, and the support plate 41 is pulled to make the support plate 41 and the rotating shaft 43 rotate along the connecting block 5, so that the support plate 41 and the support plate 41 are parallel to the sliding rod 11. At this time, the side wall of the rotating shaft 43 contacts the abutment block 52, which limits the abutment block 52 and shrinks the abutment block 52 in the sliding groove 51. The support plate 41 continues to be rotated so that the slot 42 at the end of the support plate 41 is engaged with the buckle 15 to fix the support plate 41.

[0039] Working principle: When the device needs to be used, the support plate 41 is rotated to rotate the rotating shaft 43 on the support plate 41 along the connecting block 5, so that the card slot 42 is disengaged from the buckle 15, until the bottom of the support plate 41 is parallel to the bottom of the connecting block 5, so that the two support plates 41 are unfolded, and the measuring rod 31 is pulled downward to move the connecting rod 32 out of the folding groove 34 until the connecting rod 32 is perpendicular to the sliding sleeve 14. When the connecting rod 32 is perpendicular to the sliding sleeve 14, the top of the measuring rod 31 is rotated at the other side of the connecting rod 32 at the same time, and abuts against the limit plate 35 at the top of the connecting rod 32, so that the measuring rod 31 is perpendicular to the connecting rod 32, so that the measuring rod 31 is parallel to the sliding rod 11;

[0040] Turn the knob 22 to make the knob 22 drive the rotating screw 21 to rotate, so that the knob 22 drives the moving ring 23 and the sliding sleeve 14 to move, so that the measuring plug rod 31 moves up and down, and the sliding sleeve 14 is moved to the initial position of the scale line on the sliding rod 11, so that the bottom of the measuring plug rod 31 is at the same level as the bottom of the sliding rod 11, and the sliding rod 11 and the support plate 41 are placed on the top of the cast-in-place slab, and the knob 22 is turned again to make the knob 22 drive the moving ring 23 and the sliding sleeve 14 to move downward, so that the measuring plug rod 31 moves downward and is inserted into the cast-in-place slab until the bottom of the measuring plug rod 31 contacts the bottom of the cast-in-place slab. At this time, the position of the sliding sleeve 14 on the scale line of the sliding rod 11 is observed to obtain the thickness of the cast-in-place slab.

[0041] After use, lift the measuring rod 31 upwards, so that the top of the measuring rod 31 rotates along one end of the connecting rod 32, and the other end of the connecting rod 32 rotates along the sliding sleeve 14, so that the connecting rod 32 is folded in the folding groove 34, thereby folding the measuring rod 31;

[0042] When the auxiliary support assembly 4 is folded up after use, the pull plate 54 is pulled, so that the pull plate 54 drives the abutment block 52 to slide into the sliding groove 51, so that the rotating shaft 43 is no longer limited by the abutment block 52, and the support plate 41 is pulled to make the support plate 41 and the rotating shaft 43 rotate along the connecting block 5. At this time, the side wall of the rotating shaft 43 contacts the abutment block 52, which limits the abutment block 52 and shrinks it in the sliding groove 51. The support plate 41 is continued to be rotated so that the slot 42 at the end of the support plate 41 is engaged with the buckle 15 to fix the support plate 41.

[0043] It should be noted that the various devices in this application are common devices in the market, and can be selected according to specific needs during specific use. The circuit connection relationship of each device belongs to a simple series and parallel connection circuit. There is no innovation in the circuit connection part.
