Technical Field
[0001] The utility model relates to the technical field of mined jacking engineering, and more specifically, to a connecting piece for fixing a force transfer column. Background Art
[0002] Currently, in order to reduce the negative impacts on traffic, public opinion, etc. brought by in-city construction, the number of mined jacking projects is gradually increasing. Among them, a large number of force transfer columns are required for long-distance jacking operations. Due to the large jacking force, when the force transfer columns are too long, there are risks of bending and deviation, which pose a threat to the safe operation of construction workers. Currently, it is usually adopted to limit the transmission direction of the force transfer columns by pouring concrete on the ground or embedding steel structural parts, etc. This method has problems such as increased construction costs, extended construction periods, and the non-reusability of the limiting structure.
[0003] Therefore, how to solve the above technical problems becomes the topic faced by the utility model. Content of the Utility Model
[0004] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a connecting piece for fixing a force transfer column that is convenient to use and reusable.
[0005] The technical solution adopted by the utility model to solve its technical problems is: The utility model provides a connecting piece for fixing a force transfer column, which is characterized in that it includes two pairs of back beams symmetrically and vertically arranged on the left and right sides. Two horizontally arranged lock hoop plates are fixedly connected between the two back beams on the same side. The two lock hoop plates are respectively located on the inner walls of the upper and lower sides of the back beams. Two tie rods are symmetrically and horizontally fixedly connected between the upper and lower sides of each back beam and the upper and lower sides of the back beam on the opposite side.
[0006] Horizontal sleeves that are horizontally arranged and penetrate through both sides of the force transfer column are embedded at the upper and lower sides near the edges of the two ends of the force transfer column in the transverse direction. The two pairs of tie rods respectively pass through two pairs of the sleeves on the adjacent sides of two adjacent force transfer columns, and each tie rod is fixedly connected between the corresponding two back beams.
[0007] The back beam is made of angle steel with a specification of ∟50, and its length is the same as the height of the force transfer column, and it is welded to the outer wall of the lock hoop plate far from the force transfer column.
[0008] The lock hoop plate is made of angle steel with a specification of ∟80, and its length is 40 cm.
[0009] The tie rod is a bolt with a specification of M16. The length of the bolt is more than 10 cm longer than the width of the force transfer column, and the bolt is threadedly fitted with a fastening nut.
[0010] The sleeve is made of plastic pipe with a specification of Φ20 mm.
[0011] A rubber pad is provided on the inner side of the locking hoop plate, and the thickness of the rubber pad is greater than or equal to 5 mm and less than or equal to 10 mm.
[0012] When the utility model is actually used: when manufacturing the force transfer column, a sleeve is buried in advance, the connecting piece is processed off-site, the rubber pad is pasted on the inner side of the locking hoop plate, a back beam with a suitable length is cut according to the size of the force transfer column, and is fixed on the locking hoop plate by welding. Drill a hole in the back beam along the center of the sleeve, insert the pull rod, fix the fastening nut, and tightly fix the locking hoop plate and the force transfer column through the back beam to ensure the unity of the force axis. A rubber pad with a thickness of 5-10 mm is pasted on the inner side of the locking hoop plate, and its function is to increase the friction between the locking hoop plate and the force transfer column to ensure that the position of the force transfer column does not shift during the force application. The function of the back beam is to connect the locking hoop plates on each side of the force transfer column and bear and conduct the tension of the pull rod. The pull rod passes through the sleeve to connect and fasten the locking hoop plates on both sides, and its function is to prevent the force transfer column from being displaced during the force application. The function of the sleeve is to ensure that the pull rod can pass through the force transfer column and connect the locking hoop plates on both sides of the force transfer column. It can be quickly disassembled after the current construction is completed and used for the next construction.
