[0020] Hereinafter, embodiments of the Bailey beam construction safety net installation structure of the present invention will be described with reference to the accompanying drawings.

[0021] Embodiment 1:

[0022] Figure 1-4A Bailey beam construction safety net installation structure of an embodiment of the utility model is shown, and the structure is arranged between two bridge piers 1: multiple rows of columns 2 are arranged between the two bridge piers 1, and the columns 2 include a concrete base 21 cast on the ground, a steel column 22 is fixedly installed on the top of the concrete base 21, and a sand cylinder 23 is installed on the top of the steel column 22. The surface of each steel column 22 is sleeved with a connecting piece 24, and two adjacent connecting pieces 24 are welded. Through the arrangement of the connecting piece 24, multiple concrete bases 21 in the same row have integrity, and then the overall structure of the columns 2 is made more stable, so that the columns 2 support the Bailey beams 4 more stably, and the top of each row of columns 2 is welded with a distribution beam 3, and multiple Bailey beams 4 are installed on the top of multiple columns 2. Two distribution beams 3 are welded on the top of each row of columns 2. A mounting net 6 is arranged between the beams 3, and a plurality of mounting structures 7 are welded on both sides of the distribution beam 3. The mounting structures 7 include a plurality of short columns 71 welded on the top and bottom of both sides of the distribution beam 3, and a fixing sleeve 72 is welded on the opposite ends of the two short columns 71 opposite to each other on the left and right sides, respectively. The inner cavity of the fixing sleeve 72 is slidably connected with a limiting rod 73. After the mounting net 6 is placed in the inner cavity of the mounting structure 7, the two ends of the limiting rod 73 are respectively welded to the short column 71 and the fixing sleeve 72, and a receiving rod 8 is welded between the two distribution beams 3. The receiving rod 8 is arranged at the bottom of the mounting net 6. Through the arrangement of the receiving rod 8, the bottom of the mounting net 6 is supported, thereby preventing heavy objects from falling on the top of the mounting net 6 and gathering at the center of the top of the mounting net 6 to damage the mounting net 6.

[0023] Embodiment 2:

[0024] Figure 1-4 A Bailey beam construction safety net installation structure of an embodiment of the utility model is shown, which is arranged between two piers 1: a distribution beam 3 is welded on the top of each row of columns 2, the distribution beam 3 is composed of two I-beams, a plurality of Bailey beams 4 are installed on the top of the plurality of columns 2, a bottom plate 5 is laid on the top of the plurality of Bailey beams 4, a mounting net 6 is arranged between the two distribution beams 3, a plurality of mounting structural members 7 are welded on both sides of the distribution beams 3, the mounting structural member 7 includes a plurality of short columns 71 welded to the top and bottom of both sides of the distribution beams 3, two short columns 71 opposite to each other on the left and right are respectively welded to the opposite ends of fixed sleeves 72, the inner cavity of the fixed sleeve 72 is slidably connected to the limit rod 73, and the mounting net 6 is placed in the inner cavity of the mounting structural member 7, and the two ends of the limit rod 73 are respectively welded to the short column 71 and the fixing sleeve 72.

[0025] Working principle: When the utility model is used, the user builds the bridge width according to actual needs or welds multiple installation structures 7 at the top and bottom of both sides of the distribution beam 3 according to on-site construction needs, and then hangs the installation net 6 in the inner cavity of the multiple installation structures 7 on the opposite side between the two distribution beams 3, and then rotates the limit rod 73 upward in the inner cavity of the fixing sleeve 72, and then welds the end of the limit rod 73 that is exposed to the outside to the short column 71. If it is feared that the single-sided welding is not strong enough, it can be welded again at the connection position between the fixing sleeve 72 and the limit rod 73. At this time, the limited installation of the installation net 6 is completed, and then multiple receiving rods 8 are welded between the two distribution beams 3 according to actual needs, so that the support shape of the receiving rod 8 of the installation net 6 is as follows. Figure 2 As shown, the purpose of making the installation of the safety net convenient, firm and more applicable can be achieved.
