[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a reinforced welding-free purlin, including a fixed purlin 1 and a connecting purlin 3, a cross slide groove 5 is provided on the rear side of the inner wall of the fixed purlin 1, a cross fixing plate 6 is slidably installed inside the cross slide groove 5, the left and right sides of the cross fixing plate 6 are fixedly connected with a connecting plate 7, and the two connecting plates 7 are fixedly connected with a clamping plate 8 on the far side. The left and right ends of the rear side of the connecting purlin 3 are provided with a clamping groove 9, and the middle part of the rear side of the connecting purlin 3 is provided with a connecting groove 10, the front sides of the two clamping plates 8 are respectively clamped with the corresponding clamping plates 8, and the front side of the cross fixing plate 6 is clamped with the connecting groove 10. The front side of the connecting purlin 3 and the rear side of the fixed purlin 1 are both threaded with two anchor bolts 4, and the adjacent sides of the plurality of anchor bolts 4 are respectively threadedly connected to the front side of the corresponding fixed purlin 1 and the rear side of the connecting purlin 3, and a cleaning mechanism 2 is provided on the rear side of the inner wall of the connecting purlin 3;

[0038] Specifically, align the rear side of the connecting purlin 3 with the front sides of the two engaging plates 8, and then move the connecting purlin 3 backward to engage with the engaging plates 8. Next, slide the connecting purlin 3 so that it and the cross fixing plate 6 slide downward under the limit of the cross slide groove 5. In this way, the connecting purlin 3 and the fixed purlin 1 can complete the preliminary sliding engagement. On this basis, rotate and install multiple anchor bolts 4 to complete the fixed connection of the two purlins. This connection method avoids the complicated operation of welding, improves the fixing effect of the purlin, reduces the shaking and sliding of the two purlins when they are spliced, and avoids affecting the efficiency of rivet installation and tightening. At the same time, the new connection method also greatly reduces the labor cost of operators.

[0039] Reference Figure 1 The outer walls of the two clamping plates 8 are fixedly connected with rubber sleeves 11; the outer walls of the plurality of anchor bolts 4 are fixedly connected with a plurality of protrusions 13; the middle parts of the plurality of anchor bolts 4 are fixedly connected with rubber rings 14;

[0040] Specifically, the rubber sleeve 11 improves the engagement effect between the engagement plate 8 and the engagement groove 9 , the protrusion 13 reduces the anti-slip effect of the anchor bolt 4 , and the rubber ring 14 reduces the rotation damage to the connecting purlin 3 .

[0041] Reference Figure 1 and Figure 3 The cleaning mechanism 2 includes two threaded rods 201, and the adjacent ends of the two threaded rods 201 are rotatably connected to the rear side of the inner wall of the connecting purlin 3. The two threaded rods 201 are fixedly connected to the rubber roller 202 on the far side. The outer walls of the two threaded rods 201 are threadedly connected to the slide plate 203. The left and right ends of the rear side of the inner wall of the connecting purlin 3 are provided with limiting grooves 204. The rear sides of the two slide plates 203 are respectively slidably connected to the corresponding limiting grooves 204. The bottom walls of the two slide plates 203 are fixedly connected to the return springs 205, and the bottom ends of the two return springs 205 are fixedly connected to the adsorption sponges 206.

[0042] Specifically, the downward displacement of the connecting purlin 3 enables the two rubber rollers 202 to rotate together. By driving the threaded rod 201 to rotate, the slide plate 203 can be accurately controlled to slide under the rotation limit of the limit groove 204. The movement of the slide plate 203 drives the adsorption sponge 206 fixed by the return spring 205 to slide. This design allows the adsorption sponge 206 to be tightly attached to the inner bottom wall of the fixed purlin 1, effectively removing the dirt and water vapor between the two purlins. In this way, not only the corrosion between the two purlins is reduced, but also the service life of the purlins is greatly improved.

[0043] Reference Figure 1 , Figure 2 and Figure 3The middle of the fixed purlin 1 and the rear of the middle of the connecting purlin 3 are both fixedly connected with a rubber pad 12; the surfaces of the fixed purlin 1 and the connecting purlin 3 are both provided with a galvanized layer; the outer wall of the fixed purlin 1 and the outer wall of the connecting purlin 3 are both designed to be smooth;

[0044] Specifically, the rubber pad 12 reduces the wear between the two purlins, the galvanized layer improves the corrosion resistance of the purlins, and the smooth design increases the compression resistance of the purlins.

[0045] Working principle: When starting to install, align the rear side of the connecting purlin 3 with the front side of the two clamping plates 8, move the connecting purlin 3 backward to make it engage, so as to slide the connecting purlin 3 and make it slide downward together with the cross fixing plate 6 under the limit of the cross slide 5, so that the connecting purlin 3 and the fixed purlin 1 complete the initial sliding engagement, and then rotate and install multiple anchor bolts 4 to complete the fixed connection of the two purlins, avoiding the complicated operation of welding, improving the fixing effect of the purlin, reducing the shaking and sliding of the two purlins when they are spliced ​​together, and avoiding affecting the effect of the rivet installation and fastening. The rate is improved, which greatly reduces the labor cost of operators, and through the downward sliding action of the connecting purlin 3, the two rubber rollers 202 are rotated together, thereby driving the threaded rod 201 to rotate, so that the slide plate 203 drives the adsorption sponge 206 fixed by the return spring 205 to slide under the rotation restriction of the limit groove 204, so that the adsorption sponge 206 can be closely attached to the inner bottom wall of the fixed purlin 1, thereby avoiding the existence of dirt and water vapor between the fixed purlin 1 and the connecting purlin 3, reducing the corrosion between the two purlins, and improving the service life of the purlin.
