Description

Technical Field

[0001] This utility model belongs to the technical field of building construction measurement, specifically a tool for measuring the thickness of plaster layers for cost estimation. Background Technology

[0002] In the construction and acceptance process of building projects, precise control of the plaster layer thickness is a crucial aspect of ensuring construction quality. An excessively thin plaster layer may lead to insufficient protection of the substrate, hollow areas, and cracking, while an excessively thick layer can result in material waste, increased structural load, and even compromised adhesion of the finishing layer. Therefore, accurate measurement of the plaster layer thickness is one of the key requirements for construction quality control.

[0003] A Chinese utility model patent with authorization announcement date of March 25, 2025 and authorization announcement number CN222670918U discloses a plaster layer thickness measuring device, comprising: a sleeve, a measuring rod extending through the sleeve along its central axis, one end of the measuring rod connected to a push handle, and the other end being a tip for inserting into the plaster layer, a connecting rod on the measuring rod, a scale fixed on the outer side of the sleeve, and a groove parallel to the scale on the outer side of the sleeve, the other end of the connecting rod passing through the groove and connected to a pointer for indicating the scale on the scale; and legs and a base, the number of legs being at least two, the upper end of the legs being rotatably mounted on the outer side of the end of the measuring rod protruding from the sleeve, the lower end of the legs being provided with a ball head, and the top of the base having a groove adapted to the ball head, the ball head being slidably connected to the groove and capable of omnidirectional rotation.

[0004] The existing technologies mentioned above are highly applicable and provide accurate readings. However, during the acceptance process of a house, it is necessary to test the thickness of the plaster layer on multiple walls. Typically, at least 5 points are tested for every 100 square meters of plaster area, and at least 3 points are tested for each independent space. For every additional 20 square meters, 1 to 2 additional testing points are required. The existing technologies mentioned above can only test the thickness of the plaster layer at one point at a time, resulting in low work efficiency.

[0005] Therefore, how to effectively solve the problem of low detection efficiency of plaster layer thickness measuring devices is an urgent technical issue that needs to be addressed. Utility Model Content

[0006] To address the shortcomings in the aforementioned background technology, this utility model proposes a plaster layer thickness detection tool for cost measurement, which solves the problem of low detection efficiency of plaster layer thickness measuring devices.

[0007] The technical solution of this application is as follows:

[0008] A tool for measuring plaster layer thickness in cost estimation includes measuring units that conform to the wall surface. The measuring units are symmetrically arranged about a handle, and each unit is hinged to the handle. A locking nut is provided at the hinge point between the measuring unit and the handle. When this invention is used to measure a normal wall surface, the two measuring units are parallel and side-by-side, allowing simultaneous measurement of the plaster layer thickness on both sides of the handle. When this invention is used to measure the external corner of a wall, the two measuring units are perpendicularly arranged, allowing simultaneous measurement of the plaster layer thickness on different wall surfaces on both sides of the external corner on both sides of the handle. When this invention is used to measure the internal corner of a wall, the two measuring units are perpendicularly arranged, allowing simultaneous measurement of the plaster layer thickness on different wall surfaces on both sides of the internal corner on both sides of the internal corner. This invention is simple and convenient to operate, can measure at least two points simultaneously, has high work efficiency, and provides accurate readings, minimizing errors caused by different viewing angles.

[0009] Furthermore, the handle is provided with a clearance slot for engaging the measuring unit, and a rotating shaft connected to the handle is provided in the clearance slot. The measuring unit rotates around the rotating shaft and is positioned by a locking nut.

[0010] Furthermore, two rotating shafts are arranged in parallel. Each rotating shaft is connected to a measuring unit, causing the measuring unit to rotate.

[0011] Furthermore, the measuring unit includes a rotating bracket with a through hole, through which a rotating shaft passes and is connected to a handle.

[0012] Furthermore, the upper and lower parts of the rotating bracket are provided with slide rails, the middle part of the rotating bracket is hollow, the slide rails are slidably fitted with a measuring frame, and the measuring frame is adjustablely connected to a measuring rod.

[0013] Furthermore, the hinge end of the rotating bracket is arc-shaped, which allows the two rotating brackets to rotate smoothly without obstruction.

[0014] Furthermore, the measuring rod is provided with an external thread, the measuring frame is provided with an internal threaded hole, the measuring rod is threadedly engaged with the internal threaded hole, and the insertion end of the measuring rod is provided with a tip for inserting the plaster layer.

[0015] Furthermore, the outer wall of the tip is provided with a scale. When the rotating bracket is attached to the wall, the measuring rod is rotated so that the tip of the measuring rod contacts the wall. At this time, the degree is the scale. Continue to rotate the measuring rod, and the tip of the measuring rod is inserted into the plaster layer until the tip can no longer be pushed in. Read the scale reading on the outer wall of the tip, which is the thickness of the plaster layer. The outer surface of the plaster layer can accurately point to the scale, reducing the error caused by different viewing angles of the operator.

[0016] Furthermore, the thickness of the handle flange is less than the thickness of the rotating bracket. That is, when used to measure a normal wall surface, the two rotating brackets are attached to the wall surface, and there is a gap between the side of the handle flange and the wall surface to prevent the rotating bracket from not being able to fully fit the wall surface due to the obstruction of the handle.

[0017] Furthermore, the rotating bracket has an anti-slip layer on its side, which allows the rotating bracket to better fit the wall surface and enhances stability.

[0018] The specific beneficial effects of this utility model include:

[0019] 1. This utility model is simple and convenient to operate, and can measure at least two measurement points at the same time, resulting in high work efficiency;

[0020] 2. The measurement readings are accurate and not easily affected by errors caused by different viewing angles of the operator. Attached Figure Description

The measuring units 2 are symmetrically arranged about the handle 1, and each measuring unit 2 is hinged to the handle 1. A locking nut 3 is provided at the hinge point between the measuring unit 2 and the handle 1. Figure 2 As shown, when this utility model is used to measure a normal wall surface, the two measuring units 2 are arranged parallel and side by side. After being attached to the wall surface, the locking nut 3 is tightened for positioning. The thickness of the plaster layer can be measured simultaneously on both sides of the handle 1. Figure 3 As shown, when this utility model is used to measure the external corner of a wall, the two measuring units 2 are vertically set and, after being attached to the wall, are positioned by tightening the locking nut 3. The handle 1 can simultaneously measure the thickness of the plaster layer on different wall surfaces on both sides of the external corner; for example... Figure 4 As shown, when this invention is used to measure the inside corner of a wall, the two measuring units 2 are vertically set and, after being attached to the wall, are positioned by tightening the locking nut 3. The thickness of the plaster layer on different walls on both sides of the inside corner can be measured simultaneously from both sides of the handle 1. This invention is simple and convenient to operate, can measure at least two measuring points simultaneously, has high work efficiency, and provides accurate measurement readings, which are not easily affected by errors caused by different viewing angles of the operator.

[0038] Based on the above embodiments, as a preferred embodiment, the handle 1 is provided with a clearance slot for engaging the measuring unit 2. A rotating shaft connected to the handle 1 is disposed in the clearance slot. The measuring unit 2 rotates around the rotating shaft and is positioned by a locking nut 3. The rotating shaft is fixed to the handle 1, and its end is threaded to engage with the locking nut 3. After determining the position of the measuring unit 2, the locking nut 3 is tightened to ensure that the measuring unit 2 can be vertically inserted into the plaster layer, reducing errors. After measurement, the locking nut 3 is loosened, and the unit moves to the next measurement point.

[0039] Specifically, the handle 1 is semi-circular for easy hand gripping. Each end of the semi-circular handle is connected to a flange, which are not connected to each other. A clearance slot is provided between the flanges for engaging with the measuring unit 2. The rotating shaft passes through the measuring unit 2, and both ends of the rotating shaft are inserted into the holes in the flanges.

[0040] Based on the above embodiments, as a preferred embodiment, two rotating shafts are arranged in parallel. Each rotating shaft is connected to a measuring unit 2, causing the measuring unit 2 to rotate.

[0041] Based on the above embodiments, as a preferred embodiment, the measuring unit 2 includes a rotating bracket 21 with a through hole, and the rotating shaft passes through the through hole and is connected to the handle 1.

[0042] Preferably, the rotating bracket 21 is rectangular, and a through hole is provided at the end of the rotating bracket 21. The rotating bracket 21 rotates about the rotating shaft.

[0043] Based on the above embodiments, as a preferred embodiment, the upper and lower parts of the rotating bracket 21 are provided with slide rails 22, the middle part of the rotating bracket 21 is hollow, the slide rails 22 are slidably fitted with a measuring frame 23, and the measuring frame 23 is tunably connected to a measuring rod 24.

[0044] Based on the above embodiments, as a preferred embodiment, the measuring rod 24 is provided with an external thread, the measuring frame 23 is provided with an internal thread hole, the measuring rod 24 is threadedly engaged with the internal thread hole, and the insertion end of the measuring rod 24 is provided with a tip 25 for inserting the plaster layer.

The outer surface of the locking block 233 is in contact with the inner surface of the slide rail 22, and the locking block 233 and the slide rail 22 are limited by a large frictional force.

[0046] Based on the above embodiments, as a preferred embodiment, such as... Figure 6 As shown, the outer wall of the tip 25 is provided with a scale.

[0047] Specifically, when the rotating bracket 21 is attached to the wall, the measuring rod 24 is rotated so that the tip of the measuring rod 24 contacts the wall. At this time, the degree is 0. The measuring rod 24 is rotated and the tip of the measuring rod 24 is inserted into the plaster layer until the tip 25 can no longer be pushed in. The reading on the outer wall of the tip 25 is the thickness of the plaster layer. The outer surface of the plaster layer can be accurately aligned with the scale, reducing the error caused by different viewing angles of the operator.
