Description

Technical Field

[0001] This utility model relates to the field of building materials technology, specifically to a tensile testing device for building materials. Background Technology

[0002] Building materials are the various materials used in construction projects. There are many types of building materials, which can be roughly divided into: inorganic materials, including metallic materials (including ferrous and non-ferrous metals) and non-metallic materials (such as natural stone, calcined clay products, cement, concrete and silicate products, etc.); organic materials, including plant-based materials, synthetic polymer materials (including plastics, coatings and adhesives) and asphalt materials; and composite materials, including asphalt concrete, polymer concrete, etc., which are generally composed of inorganic non-metallic materials and organic materials.

[0003] In response, Chinese patent application number CN218067373U discloses a tensile testing device for testing building materials, including a housing. A testing component is located on the left side of the housing's inner cavity, and a pulling component is located on the right side. This invention addresses the problems of poor protective performance in existing tensile testing devices. These devices fail to protect workers during tensile testing of building materials, and when excessive tensile force causes the building material to break, it poses a safety hazard to surrounding workers. Furthermore, the force generated by the breaking of the building material significantly reduces the lifespan of the testing equipment. The invention also incorporates a fixed plate, a shielding plate, a connecting seat, a tensile sensor, a fixed seat, a suspension hook, a vertical plate, a sliding rod, a connecting disc, a damping rod, a mounting base, a combination hook, an auxiliary seat, an auxiliary sliding disc, an electric telescopic rod, a connecting rope, a shielding soft plate, a pull rope, a buckle, and a locking ring.

[0004] However, existing tensile testing equipment for building materials has limitations because it requires adjustment of the testing device according to the size of the building materials, and the existing equipment can only perform tensile testing on building materials within a specific range.

[0005] Therefore, in order to solve the above problems, a tensile testing device for building materials is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a tensile testing device for building materials, in order to solve the problem mentioned in the background art of the existing tensile testing devices for building materials. Because the tensile testing of building materials requires adjustment of the testing device according to the size of the building materials, and the existing devices can only perform tensile testing on building materials within a specific range, the limitations of the device are increased.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tensile testing device for building materials, comprising: a support assembly and a worktable; the support assembly has a worktable at its upper end; the worktable has an adjustment mechanism; the adjustment mechanism has a sliding plate with pre-drilled holes; a first slider is provided on one side of the sliding plate; a first limiting bolt is provided on the first slider; a first side plate is provided on the first slider; a second slider is provided on the other side of the sliding plate; a second limiting bolt is provided on the second slider; a second side plate is provided on the second slider; a support plate is provided on one side of the worktable; a servo motor is provided on the support plate; a bidirectional screw is rotatably mounted on the output end of the servo motor via a coupling; a first threaded sleeve is provided on one side of the bidirectional screw; a second threaded sleeve is provided on the other side of the bidirectional screw; and a testing mechanism is provided on the worktable; a fixing block is provided inside the testing mechanism; a support rod is provided on the fixing block; and a scale is provided on the support rod.

[0010] Preferably, a first hook is fixedly installed on the first fixed plate, and the bottom end of the first sliding sleeve is fixedly connected to the first fixed plate through a connecting rod. A second hydraulic rod is provided on one side of the first hydraulic rod, and the bottom end of the second hydraulic rod is fixedly installed on the second side plate. A second fixed plate is fixedly installed at the telescopic end of the second hydraulic rod, a second hook is fixedly installed on the second fixed plate, and the second sliding sleeve is fixedly connected to the second fixed plate through a connecting rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. An adjustment mechanism is provided to adjust the spacing between the detection devices. A servo motor within the mechanism drives a bidirectional screw to rotate, which in turn moves the first and second threaded sleeves. This allows the first and second side plates to slide on the slide plate. During this process, the first and second sliders support and limit the movement of the first and second side plates. The first and second limit bolts further support and limit the movement of the first and second side plates, thus improving the practicality of the device.

[0016] 2. The device is equipped with a testing mechanism that allows for tensile testing of building materials. By fixing the two ends of the building material with the first and second hooks, respectively, the first and second hydraulic rods can be activated to move the first and second fixed plates in opposite directions. This causes the first and second hooks to stretch the building material. During this process, the first fixed plate can move the second sliding sleeve on a scale, and the second fixed plate can move the first sliding sleeve on the scale to record the data on the scale, thus improving the device's working efficiency.
