in the figure: the connecting piece 1, the bolt 2, the split screw 3, the fastening nut 4, the cotter 5, the through hole 101, the upper plate 102, the lower plate 103, the limiting part 201, the mounting hole 202, the limiting hole 203, the inserting part 501, the head part 502 and the clamping part 503.
Detailed Description
As shown in fig. 1-3, a fastening device for corner templates comprises connecting pieces 1 respectively arranged at the outer sides of two corner templates, a through hole 101 is formed in the end portion of each connecting piece 1, a bolt 2 is inserted into the through hole 101, a limiting portion 201 is arranged at the upper end of the bolt 2, the limiting portion 201 can be set to be a nut, a mounting hole 202 is formed in the bolt 2, and two ends of a tension screw rod 3 respectively penetrate through the mounting holes 202 of the two bolts 2 and then are fastened through fastening nuts 4.
During the specific use, connecting piece 1 links to each other with the I-beam of corner template, forms the horizontal pressure roof beam of template system, with bolt 2 cartridge in through-hole 101, according to template installation angle, adjusts the direction of mounting hole 202 on the bolt 2 to be applicable to different structure appearance angles, will pass mounting hole 202 to the blind screw 3, after the volume of awaiting measuring lofting location, install fastening nut 4 at the both ends of blind screw 3, screw up the reinforcement.
The fastening device is used for connecting and fastening the corner template, the installation process is simple and clear, the device is applicable to any shape angle of the structure, and the construction efficiency is improved.
Preferably, the connecting member 1 includes an upper plate 102 and a lower plate 103 provided on the corner mold plate, a through hole 101 penetrates the upper plate 102 and the lower plate 103, and a counter screw 3 is provided between the upper plate 102 and the lower plate 103.
The counter-pull screw 3 is arranged between the upper plate 102 and the lower plate 103, the upper plate 102 and the lower plate 103 can limit the counter-pull screw 3 up and down, and the situation that the tightening nut 4 is loosened and the tightening is affected due to the vibration of the counter-pull screw 3 in pouring or vibrating is prevented.
Furthermore, the lower end of the bolt 2 is provided with a limiting hole 203, and a cotter pin 5 is arranged in the limiting hole 203. Through setting up split pin 5, can further prevent that bolt 2 or fastening nut 4 pine from taking off, guarantee firm in connection.
Further, as shown in fig. 4, the cotter 5 includes an inserting portion 501, a head portion 502 and a clamping portion 503, the inserting portion 501, the head portion 502 and the clamping portion 503 are integrally formed, and the clamping portion 503 is an arc-shaped structure adapted to the outer side of the plug 2.
The split pin of this structure, because clamping part 503 is the arc structure with 2 outside adaptations of bolt, can guarantee the levelness that bolt 2 inserted spacing hole 203 to can guarantee that split pin 5 can hug closely hypoplastron 103 bottom, guarantee spacing degree of accuracy.
