A leveling and spacing device may include an elongated device body. A level may be provided on the device body. At least two spaced-apart member notches may be provided in the device body. Accordingly, a first structure member of the building structure may initially be deployed in place in the structure. The device body of the leveling and spacing device may be deployed in place on the first structure member by inserting the first structure member into a first member notch in the device body. A second structure member may then be positioned adjacent to the first structure member and in alignment with a second member notch in the device body. The device body may then be lowered in place onto the second structure member as a second member notch receives the second structure member. The second structure member may then be attached to the first structure member, and the process repeated.

The utility model discloses a fixed ruler capable of adjusting spacing. The fixed ruler comprises two fixed parts and two horizontal scales which are respectively connected with the two fixed parts, one side of each fixing part comprises a magnetic strip, the two fixing parts are oppositely arranged, and the two magnetic strips are located on the outer sides of the two opposite fixing parts respectively; scales are arranged on the two horizontal scales, and the free ends of the two horizontal scales are connected through a telescopic joint; a passing cavity allowing the two horizontal rulers to jointly penetrate through is formed in the telescopic connector, and a positioning device is arranged on the rear portion of the telescopic connector. According to the utility model, the magnetic strip is adsorbed on the steel skeleton, the horizontal scale is vertical to the adsorbed steel skeleton, the length of the horizontal scale can be adjusted, and after the horizontal scale is adjusted to a required length, the horizontal scale is fixed by the positioning device to ensure that the distance between the two fixing parts is fixed, so that one of the fixing parts is adsorbed on the steel skeleton during use; therefore, the position where the next steel skeleton needs to be placed can be obtained, the construction efficiency is high, and the quality is guaranteed.

A template for determining a stretching ratio of a film sample of a film spanning a round bale includes a template body which has a supporting side and an oppositely arranged working side. The template body includes an outline edge defining a perimeter of a film sample. Two slots are formed in the template body for applying markings to the film, the two slots being arranged parallel to each other at a first distance. A contact marking is arranged on the working side of the template body. A scale for displaying the stretching ratio of the film sample is arranged on the working side at a predetermined distance from the contact marking.

The utility model relates to the technical field of measuring tools, and provides a multifunctional measuring tool for building detection, which comprises an upper connecting piece and a lower connecting piece, a square mounting groove is formed in the lower connecting piece, a first through hole is formed in the inner upper side wall of the square mounting groove, a circular mounting groove is formed in the upper connecting piece, and a second through hole is formed in the lower side wall of the circular mounting groove. A second through opening is formed in the inner lower side wall of the circular mounting groove, a sliding hole is formed in the inner upper side wall of the circular mounting groove, a sliding rod is slidably connected into the sliding hole, a positioning gear is connected to the bottom end of the sliding rod, a connecting rod is connected to the bottom end of the positioning gear, and a square block slidably connected with the square mounting groove is connected to the bottom end of the connecting rod; and a reset spring is arranged between the square block and the inner lower side wall of the square mounting groove, and an inner gear ring meshed with the positioning gear is arranged on the inner side wall of the circular mounting groove, so that when the adjusting angle is too large, the reset spring is prevented from being twisted and deformed, and the purpose of prolonging the service life of equipment is achieved.

The utility model relates to a tool for measuring the position of a bridge prestressed anchor bearing plate, and relates to the technical field of bridge construction. A tool for measuring the position of a bridge prestressed anchor bearing plate comprises a rod ruler, a cone and a horizontal ruler. The cone is installed on the leveling instrument, the leveling instrument with the cone can accurately position the circle center of the circular hole of the anchor backing plate, the upper edge of the leveling instrument is flush with the circle center of the anchor backing plate, and the vertical height value of the circle center of the anchor backing plate can be visually read after the leveling instrument is adjusted to be horizontal, so that the safety of a bridge is guaranteed. The device is convenient to operate, convenient to disassemble and assemble, capable of guaranteeing the precision and convenient to transport, and measurement work can be independently completed through one operation.
