Description

Technical Field

[0001] This utility model relates to the field of engineering measurement technology, specifically an insertable floor slab thickness detector. Background Technology

[0002] In the field of building construction quality supervision, floor slab thickness is a core indicator of structural safety and durability, and its accurate detection directly affects building acceptance standards and subsequent performance. Traditional testing techniques mainly rely on two types of methods: one is destructive testing (such as core drilling), which requires drilling holes in the floor slab surface and measuring manually with calipers, resulting in problems such as damage to structural integrity, high repair costs, and limited data; the other is non-destructive testing (such as ultrasonic and radar methods), which avoids structural damage but is limited by expensive equipment, sensitivity to environmental interference (such as humidity and rebar density), and high operational expertise requirements. For example, ultrasonic instruments are prone to signal attenuation in multi-layered rebar mesh or composite floor slabs with cavities. In addition, existing equipment mostly focuses on single-point measurement and lacks the ability to analyze the uniformity of floor slab thickness from multiple dimensions. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an insertable floor slab thickness detector, which solves the problems of cumbersome and inconvenient measurement and low measurement accuracy of traditional measuring equipment by setting an all-round measuring component combined with a transmission measuring component.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an insertable floor slab thickness detector, including a mounting cylinder, a fixing foot plate fixedly provided at the lower end of the mounting cylinder, a first fixing sleeve fixedly sleeved on the outer wall of the mounting cylinder near the lower end, a second fixing sleeve fixedly sleeved on the outer wall of the mounting cylinder near the upper end, a vertical measuring rod fixedly connected between the first fixing sleeve and the second fixing sleeve, a dimension measuring device slidably sleeved on the measuring rod, a horizontal connecting support rod fixed at the bottom of the dimension measuring device, the connecting support rod being fixed externally to a mounting ring, an annular limiting groove being opened on the top surface of the mounting ring, an omnidirectional measuring component being slidably arranged in the limiting groove, a measuring column being sleeved through the mounting cylinder, and the measuring column being connected and fixed to the dimension measuring device through a transmission measuring component.

[0005] In a preferred embodiment, the omnidirectional measuring component includes a mounting block movably disposed in the upper limit groove of the mounting ring, a vertical multi-directional measuring rod slidably disposed on the mounting block, and a measuring foot fixed to the lower end of the multi-directional measuring rod.

[0006] In a preferred embodiment, a locking post is horizontally inserted through the side wall of the mounting block, and the locking post is threadedly engaged with the mounting block. One end of the locking post extends into the mounting block and presses against the multi-directional measuring rod that passes through the mounting block.

[0007] In a preferred embodiment, the transmission measuring assembly includes a third fixed sleeve fixedly sleeved on the measuring column, a measuring column fixedly inserted through the third fixed sleeve, and the lower end of the measuring column passing through the second fixed sleeve and fixedly connected to the dimension measuring instrument.

[0008] In a preferred embodiment, a pressing ball is fixedly connected to the top of the measuring column.

[0009] In a preferred embodiment, a positioning screw is threaded through the outer wall of the mounting cylinder, and the positioning screw passes through the mounting cylinder and presses against the measuring column passing through the mounting cylinder.

[0010] In a preferred embodiment, the mounting block and the limiting groove are in a sliding fit, the mounting block can rotate and slide 360° along the annular trajectory of the limiting groove, and the bottom of the mounting block is in close contact with the bottom surface of the limiting groove.

[0011] In a preferred embodiment, both the measuring rod and the multi-directional measuring rod are provided with scales.

[0012] The insertion-type floor slab thickness detector provided by this utility model, by adopting the above-described structure, has the following beneficial effects: (1) By integrating the all-round measurement component and the transmission measurement component, the multi-directional synchronous detection of floor slab thickness is realized, which solves the problem of limited measurement range of traditional equipment and significantly improves the comprehensiveness of data; (2) The sliding fit between the measuring rod and the size measuring instrument, combined with real-time feedback from the digital display screen, ensures measurement accuracy down to the millimeter level and reduces human error. The design of the pressing ball and locking column simplifies the operation process. The measuring column can quickly descend to the reserved hole and automatically trigger data recording through the transmission component, which greatly improves the detection efficiency.

[0016] like Figure 1-3 A type of insertable floor slab thickness detector includes an installation cylinder 1. A fixing foot plate 3 is fixedly provided at the lower end of the installation cylinder 1. A first fixing sleeve 2 is fixedly sleeved on the outer wall of the installation cylinder 1 near the lower end. A second fixing sleeve 7 is fixedly sleeved on the outer wall of the installation cylinder 1 near the upper end. A vertical measuring rod 14 is fixedly connected between the first fixing sleeve 2 and the second fixing sleeve 7. A dimension measuring device 8 is slidably sleeved on the measuring rod 14. A horizontal connecting support rod 15 is fixed at the bottom of the dimension measuring device 8. The connecting support rod 15 is externally fixed to an installation ring 4. An annular limiting groove 9 is opened on the top surface of the installation ring 4. An all-around measuring component 5 is slidably arranged in the limiting groove 9. A measuring column 13 is sleeved through the installation cylinder 1. The measuring column 13 and the dimension measuring device 8 are connected and fixed through a transmission measuring component 6.

[0017] In a preferred embodiment, the omnidirectional measuring component 5 includes a mounting block 51 movably disposed in the upper limit groove 9 of the mounting ring 4, a vertical multi-directional measuring rod 52 slidably disposed on the mounting block 51, and a measuring foot 54 fixed at the lower end of the multi-directional measuring rod 52.

[0018] In a preferred embodiment, a locking post 53 is horizontally inserted through the side wall of the mounting block 51. The locking post 53 is threadedly engaged with the mounting block 51. One end of the locking post 53 extends into the mounting block 51 and presses against the multi-directional measuring rod 52 that passes through the mounting block 51.

[0019] In a preferred embodiment, the transmission measuring assembly 6 includes a third fixed sleeve 61 fixedly sleeved on the measuring column 13, a measuring column 62 fixedly passing through the third fixed sleeve 61, and the lower end of the measuring column 62 passing through the second fixed sleeve 7 and fixedly connected to the size measuring instrument 8.

[0020] In a preferred embodiment, a pressing ball 10 is fixedly connected to the top of the measuring column 13.

[0021] In a preferred embodiment, a positioning screw 12 is threaded through the outer wall of the mounting cylinder 1, and the positioning screw 12 is inserted into the mounting cylinder 1 and presses against the measuring column 13 passing through the mounting cylinder 1.

[0022] In a preferred embodiment, the mounting block 51 and the limiting groove 9 are adapted to slide together, and the mounting block 51 can rotate and slide 360° along the annular trajectory of the limiting groove 9, and the bottom of the mounting block 51 is in close contact with the bottom surface of the limiting groove 9.

[0023] In a preferred embodiment, both the measuring rod 14 and the multi-directional measuring rod 52 are provided with scales.

[0024] In the implementation of this utility model, the operator places the device at the position where thickness measurement is required. Then, the third fixing sleeve 61 drives the measuring column 62 and the measuring column 13 to move down simultaneously. The measuring column 13 extends through the bottom wall of the fixing foot plate 3 into the reserved hole. During the downward movement, the measuring column 62 moves along the measuring rod 14 driven by the dimension measuring device 8. The dimension measuring device 8 starts counting. When the bottom of the measuring column 13 contacts the support plate at the bottom of the reserved hole, the measurement is completed. At this time, the operator can obtain the measured thickness data through the counting display screen 11 on the measuring column 13 or the dimension measuring device 8. This measurement method is convenient and efficient. At the same time, during the measurement process, the measuring foot 54 contacts the top surface of the measuring plate, and the mounting ring 4 can drive the mounting block 51 to move down. The mounting block 51 moves down relative to the multi-directional measuring rod 52 and can also count. The operator can rotate the mounting block 51 around the mounting ring 4. This method can measure the thickness of the plate around the reserved hole, thereby detecting whether the plate thickness is uniform and obtaining more convincing measurement results.
