Description

Technical Field

[0001] This utility model belongs to the field of building mortar strength testing technology, and in particular relates to a penetration-type building mortar strength tester. Background Technology

[0002] Penetration testing of mortar strength is based on the principle of penetration resistance. It calculates the compressive strength of mortar by measuring the depth to which a specific probe penetrates the mortar. During testing, a penetration tester is used to press the probe into the mortar surface, and the penetration depth is recorded. The compressive strength is then calculated based on a pre-established curve showing the relationship between penetration depth and mortar strength. This method is suitable for testing masonry mortar strength in the range of 1.0 MPa to 20.0 MPa, and is particularly suitable for quality acceptance of masonry structures and the evaluation of existing buildings. Compared to traditional sampling testing, penetration testing has advantages such as non-destructive testing, convenient operation, and intuitive results. During testing, attention should be paid to the influence of factors such as mortar surface flatness and probe perpendicularity on the results. Multiple measurements at different locations may be necessary to improve accuracy. The test results can be used to determine whether the mortar strength meets design requirements or to assess the aging and deterioration of mortar in existing buildings.

[0003] Comparing with Chinese Patent CN219957250U, a penetration-type mortar strength tester for building inspection is disclosed. The tester includes a housing, a fixing sleeve fixedly connected to the bottom outer wall of the housing, and a circular opening on the top inner wall of the fixing sleeve. A connecting rod is slidably connected to the inner wall of the circular opening, and a mounting base is fixedly connected to the bottom outer wall of the connecting rod. A circular groove is formed on the bottom outer wall of the mounting base, and a mounting sleeve is fixedly connected to the top inner wall of the groove. The outer wall of the mounting sleeve has four openings, and connecting blocks are slidably connected to the inner walls of each of the four openings. This invention overcomes the shortcomings of existing technologies by incorporating two adjustable arc-shaped plates within the mounting base. These plates quickly clamp the test pins, facilitating rapid replacement of the test pins. The arc-shaped plate clamping effectively prevents mortar from affecting the installation of the test pins.

[0004] However, the bottom of the aforementioned patent is a ring, which can only be positioned close to a flat surface. It is difficult to position the mortar in the wall cracks to ensure the accuracy of the strength test. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide a penetration-type building mortar strength tester to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A penetration-type building mortar strength tester includes a main unit for penetration force testing, and a planar positioning device for circumferential contact testing surface positioning inserted at the bottom of the main unit. The planar positioning device is provided with a narrow slit positioning device for sliding outward insertion into a wall slit for positioning. The planar positioning device includes a positioning sleeve with a limiting platform in the middle and an clearance hole in the middle. The positioning sleeve has storage structures on both sides for connecting the narrow slit positioning device. The narrow slit positioning device includes a limiting slip ring with two symmetrically arranged outward protrusions for insertion into the narrow slit for positioning. A limiting pin is installed on one side of the limiting slip ring.

[0008] Furthermore: the main unit includes a main body, two handles are symmetrically arranged on the top of the main body, a trigger handle is provided on one side of the main body, and a connector is provided at the bottom of the main body.

[0009] Furthermore, a detection pin is installed in the middle of the bottom surface of the connector, and the connector clamps the detection pin by a locking sleeve.

[0010] Furthermore, the storage structure includes two storage slots symmetrically arranged at the bottom end of the positioning sleeve and a limiting slot arranged on the side of the positioning sleeve.

[0011] Furthermore: an anti-slip rubber pad is attached to the inner wall of the top of the positioning sleeve, and the limiting platform and the positioning sleeve are integrally formed.

[0012] Furthermore, the limiting groove is L-shaped.

[0013] Furthermore: the protruding structure includes a positioning block, a connecting column is provided on the top of the positioning block, and a support platform is provided at the opposite ends of the two positioning blocks.

[0014] Furthermore, the positioning block is a rectangular prism with a height greater than 1 cm and a length greater than 2 cm.

[0015] Compared with existing technologies, the beneficial effects are:

[0016] 1. By modularly switching between a planar positioning device (the positioning sleeve is tightly attached to the detection plane) and a narrow gap positioning device (the slidable protruding positioning block is inserted into the wall gap), accurate detection of planar mortar and wall gap mortar can be achieved. This solves the problem that traditional equipment is difficult to locate in narrow gaps. It is especially suitable for areas that are difficult to locate with traditional testing instruments, such as wall joints and pipe edges, thus expanding the application range of the penetration method.

[0017] 2. The narrow slit positioning device achieves one-button adjustment through the sliding structure of L-shaped limiting groove and limiting pin. Simply loosening / tightening the limiting pin is enough to switch between the flat mode and the narrow slit mode without disassembling any parts, thus improving efficiency.

[0018] 3. The limiting platform and the one-piece molded positioning sleeve ensure consistent insertion depth and prevent equipment shaking during insertion. When inspecting narrow gaps, the support platform holds the bottom of the positioning sleeve, and the rigid support of the protruding positioning block ensures that the inspection nail is perpendicular to the wall gap. The positioning block adopts a rectangular column design to enhance the contact area and stability after insertion into the wall gap and avoid measurement errors caused by tilting.

[0030] In this embodiment: the narrow slit positioning device includes a limiting slip ring 301, which has two symmetrically arranged protruding structures for insertion into the narrow slit for positioning. A limiting pin 302 is installed on one side of the limiting slip ring 301.
