Description

Technical Field

[0001] This utility model relates to the field of field testing technology, specifically a reference beam with movable slide rails for floor slab load testing. Background Technology

[0002] Currently, in floor slab load tests, a reference beam is required to measure floor slab displacement. Conventional reference beams are mostly made of ordinary rectangular steel tubes. For dial indicator installation, a magnetic base is used to attach it to the surface of the rectangular steel tube. When installing the dial indicator, the magnetic base needs to be adjusted to match the measuring point position. However, when installing the other side, touching the rectangular steel tube can cause the installed magnetic base to move and deviate. Therefore, installing the magnetic base requires two to three people working together.

[0003] In view of this, existing technologies may already provide solutions to the above problems, but this case aims to provide an alternative or replacement technical solution. Summary of the Invention

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a reference beam with movable slide rail for floor slab load testing, comprising a reference beam on which a movable slide rail assembly is movably mounted; The movable slide rail assembly includes: a top plate, locking holes, two side wall plates, four positioning grooves, eight ball bearings, and a fixing rod; The top plate is movably mounted on top of the reference beam. A locking hole is provided at the center of the top plate. The two side wall plates are fixedly installed on the lower sides of the top plate. Four positioning grooves are evenly provided on the inner side wall of the side wall plate. The eight balls are movably embedded in the four positioning grooves evenly provided on the inner side wall of the two side wall plates in groups of four. The fixing rod is movably installed in the locking hole.

[0005] Preferably, the inner wall of the locking hole is threaded.

[0006] Preferably, the lower end of the fixing rod is threaded.

[0007] Preferably, the two sidewall panels are symmetrically installed on both sides of the top plate.

[0008] Preferably, the two sidewall panels are made of steel plates. Beneficial effects

[0009] This invention provides a reference beam with a movable slide rail for floor slab load testing, offering the following advantages: Through its innovative movable slide rail assembly design, this invention effectively solves the inherent drawback of traditional magnetic dial indicator placement requiring multiple operators. The assembly, with its stable sliding frame formed by the top plate and side wall plates, and ball bearings embedded in the inner positioning groove, allows the dial indicator to move easily and smoothly along the reference beam to any measuring point and achieve precise positioning. This enables a single person to quickly complete the installation and adjustment of all measuring instruments, significantly improving installation efficiency and operational convenience. Furthermore, the threaded fixing rod and locking hole ensure the slide rail assembly is securely locked in any position, fundamentally preventing displacement due to accidental contact or vibration during the test, greatly guaranteeing the stability of the measurement process and the accuracy of the data. In addition, the device has a simple structure, primarily using conventional materials such as steel plates, resulting in low manufacturing and maintenance costs, strong versatility, and high practical value for widespread application.

[0015] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example: Please refer to Figure 1-4 A reference beam for floor slab load testing with movable slide rails includes a reference beam 1, on which a movable slide rail assembly is movably mounted; The movable slide rail assembly includes: a top plate 2, locking holes 3, two side wall plates 4, four positioning grooves 5, eight ball bearings 6, and a fixing rod 7; The top plate 2 is movably mounted above the reference beam 1. A locking hole 3 is provided at the center of the top plate 2. Two side wall plates 4 are fixedly installed on the lower sides of the top plate 2. Four positioning grooves 5 are evenly provided on the inner side wall of the side wall plate 4. Eight ball bearings 6 are movably embedded in the four positioning grooves 5 evenly provided on the inner side wall of the two side wall plates 4 in groups of four. The fixing rod 7 is movably installed in the locking hole 3.

[0017] In use, the operator first fixes the reference beam 1 to the floor slab or test platform, ensuring it is level and stable. The reference beam 1 is a long strip of metal with a smooth surface that facilitates sliding. At the start of the experiment, the operator assembles the moving slide rail assembly, vertically welding the two side wall plates 4 to the lower sides of the top plate 2 to form a "U" shape. The side wall plates 4 are ensured to be parallel and perpendicular to the top plate 2. Roller balls 6 are embedded in the four positioning grooves 5 of each side wall plate 4. The positioning grooves 5 are used to fix the position of the roller balls 6, ensuring that the roller balls 6 are evenly distributed and can roll freely within the grooves. To reduce friction with the reference beam 1, the ball bearing 6 acts as a rolling element, directly contacting the reference beam 1 and converting sliding friction into rolling friction. This allows the moving slide rail assembly to move easily and accurately along the reference beam 1. The moving slide rail assembly is then fitted onto the reference beam 1, and the dial indicator is mounted on the moving slide rail assembly using a magnetic base. The moving slide rail assembly can quickly match the measuring point position for easy testing. A locking hole 3 is machined at the center above the top plate 2 for inserting the fixing rod 7. When the dial indicator needs to be fixed, it is locked by the fixing assembly through the locking hole 3 to prevent accidental movement.

[0018] In practical implementation, the inner wall of the locking hole 3 is threaded, and the lower end of the fixing rod 7 is threaded. During use, the thread at the lower end of the fixing rod 7 engages with the internal thread of the locking hole 3, which can quickly fix the moving slide rail assembly on the reference beam 1 and prevent it from moving accidentally.

[0019] In practice, the two side wall panels 4 are symmetrically installed on both sides of the top plate 2. During use, the stacked symmetrical structure ensures that the load is evenly distributed, preventing jamming, accelerated wear, or even structural damage caused by uneven loading.

[0020] In the specific implementation process, the two side wall plates 4 are made of steel plates. The high hardness and wear resistance of steel ensure the long-term use of the positioning grooves 5, while also facilitating the magnetic base's adsorption.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
