Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example 1: as shown in fig. 1 and 2, the roof joist comprises a pair of mounting plates 1 and a cross beam 2 arranged between the pair of mounting plates 1. The lower end face of the beam 2 is provided with a weight reduction groove 3, and a plurality of reinforcing ribs 31 are uniformly arranged in the weight reduction groove 3 at intervals.
When the joist is installed, the installation plates 1 are fixed on a pair of adjacent main beams through bolts, then the cross beam 2 is lifted, one end of the cross beam 2 with the weight reduction groove 3 faces downwards, and then the cross beam 2 is fixed between the installation plates 1, so that the installation and the use of the whole joist can be completed.
As shown in fig. 3, both ends of the cross beam 2 are provided with mounting rods 21, and the ends of the mounting rods 21 are provided with positioning blocks 22. The lateral wall of mounting panel 1 is provided with mount pad 4, is provided with mounting groove 41 and the constant head tank 42 of mutual intercommunication on the mount pad 4, and mounting groove 41 supplies installation pole 21 embedding, and constant head tank 42 supplies locating piece 22 embedding.
When mounting the mounting plate 1, the end of the mounting seat 4 with the mounting groove 41 and the positioning groove 42 is upward, and then the beam 2 is lifted up, so that the mounting rods 21 and the positioning blocks 22 at the two ends of the beam 2 are located above the mounting groove 41 and the positioning groove 42. The position of the positioning block 22 is then adjusted so that the positioning block 22 and the mounting rod 21 are aligned with the mounting groove 41 and the positioning groove 42. And then the beam 2 is driven to slowly move downwards, so that the positioning block 22 and the mounting rod 21 are embedded into the positioning groove 42 and the mounting groove 41, and the mounting of the whole joist can be realized.
As shown in fig. 3, a locking hole 43 communicating with the positioning groove 42 is formed through a side wall of the mounting seat 4, and a locking plate 5 for pressing an upper end surface of the positioning block 22 is inserted into the locking hole 43. The lock plate 5 is provided with a shutter 51 at one end and a pair of hold-down plates 52 at the other end.
As shown in fig. 3, the outer wall of one side of the mounting seat 4 is provided with a groove 44 for the baffle 51 to be embedded in, and the outer wall of the other side is provided with a clamping groove 45 for the compression plate 52 to be embedded in.
After the positioning block 22 is completely inserted into the positioning slot 42, the locking plate 5 and the pressing plate 52 are inserted into the locking hole 43, and then the baffle 51 is pushed to slide the locking plate 5 and the pressing plate 52 along the inner wall of the locking hole 43. Until the baffle 51 is embedded into the groove 44, one of the pressing plates 52 is knocked to be bent upwards, so that the pressing plate is embedded into the clamping groove 45 and presses the side wall of the mounting seat 4. Another pressing plate 52 is knocked to bend downwards, so that the pressing plate is embedded into the clamping groove 45 and presses the side wall of the mounting seat 4. The positioning block 22 is pressed and fixed, and the locking plate 5 is fixed at the same time.
The working principle is as follows: when the joist is installed, the installation plates 1 and the installation seats 4 are fixed on an adjacent pair of main beams, and then the cross beam 2 is lifted, so that the installation rods 21 and the positioning blocks 22 at the two ends of the cross beam 2 are positioned above the installation grooves 41 and the positioning grooves 42. And finally, the beam 2 is driven to move downwards, so that the installation of the whole joist can be realized after the installation rod 21 and the positioning block 22 are embedded into the installation groove 41 and the positioning groove 42.
Example 2: as shown in fig. 3 and 4, the difference from embodiment 1 is that a pair of mounting brackets 6 are disposed on the upper end surface of the mounting seat 4, and the mounting brackets 6 are distributed at two ends of the positioning groove 42. The lower end surface of the mounting rack 6 is provided with a plurality of positioning rods 61, and the upper end surface of the mounting seat 4 is provided with positioning holes 46 for the positioning rods 61 to be inserted.
As shown in fig. 4, a support bar 62 is horizontally arranged on the mounting frame 6 along the length direction thereof, a collar 63 is rotatably connected to the outer wall of the support bar 62, and a guide plate 7 is arranged on the collar 63. The inside wall of deflector 7 is provided with a pair of limiting plate 8, and the distance between the limiting plate 8 is the flaring setting from bottom to top.
In this embodiment, when a pair of deflector 7 is in vertical state, the inside wall of deflector 7 is the both ends inner wall parallel and level of constant head tank 42 to the lower extreme inner wall of limiting plate 8 is the both sides inner wall parallel and level of constant head tank 42.
Therefore, when the cross beam 2 is installed, the installation frame 6 is firstly placed on the upper end surface of the installation seat 4, and the installation frame 6 is installed on the installation seat 4 after the positioning rod 61 at the lower end of the installation frame 6 is inserted into the positioning hole 46 on the upper end surface of the installation seat 4. Then, the guide plates 7 are driven to drive the limiting plates 8 to turn over, so that the pair of guide plates 7 are in a horizontal state, and the limiting plates 8 face upwards.
When the beam 2 and the positioning block 22 move downwards, the positioning block 22 abuts against the inner wall of the guide plate 7 and is located between the pair of limiting plates 8. At this time, the positioning block 22 presses the pair of guide plates 7 to turn over, and continuously slides downward along the inner walls of the guide plates 7 and the stopper plate 8.
When the positioning block 22 moves downwards, the pair of guide plates 7 automatically straightens the two ends of the positioning block 22, and the pair of limiting plates 8 automatically straightens the two sides of the positioning block 22. When the pair of guide plates 7 is in a vertical state, the guide plates 7 clamp both ends of the positioning block 22, and the limit plates 8 clamp both sides of the positioning block 22.
At this time, the positioning block 22 is completely aligned with the positioning groove 42, and then the positioning block 22 is driven to slide into the positioning groove 42 along the inner walls of the guiding plate 7 and the limiting plate 8. Thereby accomplish the installation of crossbeam 2, and then make the installation of whole crossbeam 2 convenient and fast more, reached the effect of easy to assemble use.
Example 3: a prefabrication process for installing joists, which is used for installing the joists, comprises the following steps: s1: the mounting plates 1 are abutted to the main beams, the levelness of the upper end faces of the mounting plates 1 is measured, then the peripheries of the mounting plates 1 are fixed on the main beams respectively by using bolts, and the upper end faces of the mounting plates 1 are in a state of equal height.
S2: the mounting bracket 6 is mounted on the upper end surface of the mounting base 4.
S3: the end of the beam 2 with the weight-reducing slots 3 is directed towards the ground, and then the beam 2 is lifted so that the mounting rods 21 and the positioning blocks 22 at the two ends of the beam 2 are located directly above the mounting frame 6.
S4: the driving beam 2 moves downward, the guide plate 7 and the limit plate 8 guide the positioning block 22 to move downward, and the positioning block 22 and the mounting rod 21 are inserted into the positioning groove 42 and the mounting groove 41.
S5: the mounting frame 6 is removed.
S6: the locking plate 5 is inserted into the locking hole 43 to fix the positioning block 22.
S7: the shutter 51 is abutted against the mounting seat 4, and then the pressing plate 52 is bent.
S8: and (4) spray painting treatment, namely spraying antirust paint on the surface of the whole joist.
