[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains; the terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention; the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0043] like Figures 1 to 9As shown, the present application proposes a steel truss thin-walled plate with adjustable steel mesh size, including a support assembly 100, the support assembly 100 includes a lower chord steel bar 101, a web bar 103, an upper chord steel bar 104 and a bottom form 105, the upper chord steel bar 104 and the lower chord steel bar 101 are welded to the web bar 103, and the bottom form 105 is a rectangular plate made of concrete; it also includes a steel mesh 102 and an adjustment assembly 200; the steel mesh 102 is located at the bottom of the support assembly 100, and the steel mesh 102 and the support assembly 100 are fixed together by welding. The steel mesh 102 is composed of mutually perpendicular steel bars. The size of the steel mesh 102 is adjusted by adjusting the distance between the steel bars constituting the steel mesh 102. For thin-walled panels of different sizes, the sizes of the steel mesh 102 cast therein are also different. The larger the size of the thin-walled panel, the greater the pressure it needs to withstand. Therefore, the distance between the steel bars constituting the steel mesh 102 is smaller. The thin-walled panel is cast first and then cut into different sizes. Therefore, it is necessary to adjust the steel mesh 102 to the appropriate position before casting the bottom form 105. The adjustment assembly 200 includes a sliding sleeve 201, a support rod 202, a movable plate 203, a spring pin 204 and a fixed rod 206; the sliding sleeve 201 is a rectangular rod with a through hole, and the steel mesh 102 passes through the sliding sleeve 201. The sliding sleeve 201 can slide on the steel bars constituting the steel mesh 102, and the size of the steel mesh 102 can be adjusted by adjusting the position of the sliding sleeve 201; the support rod 202 is fixed to the upper side of the sliding sleeve 201, and the support rod 202 is a hollow cylindrical rod; the movable plate 203 is an arc plate, which constitutes the steel mesh The steel bars of the mesh 102 can pass through and slide between the movable plate 203 and the sliding sleeve 201, thereby adjusting the size of the steel mesh 102. The fixed rod 206 is fixedly connected to the bottom of the movable plate 203, and the fixed rod 206 is slidably connected to the support rod 202; the spring pin 204 is fixed on the side wall of the fixed rod 206, and the spring pin 204 can be clamped in the support rod 202 to fix the movable plate 203 on the sliding sleeve 201. At this time, the steel mesh 102 is fixed at the specified position, thereby determining the size of the steel mesh 102.

[0044] Preferably, an annular baffle 205 is fixedly connected to the top of the support rod 202, and the diameter of the central circular hole of the baffle 205 is smaller than the diameter of the internal circular hole of the support rod 202; the baffle 205 can limit the movement range of the fixed rod 206 within the support rod 202, and the bottom of the fixed rod 206 has the same diameter as the internal circular hole of the support rod 202; a groove is provided near the bottom position of the internal circular hole of the support rod 202, and the spring pin 204 can extend into the groove. When the size of the steel mesh 102 needs to be adjusted again, the movable plate 203 is pulled outward to make the spring pin 204 slide out of the groove inside the support rod 202, so that the movable plate 203 and the steel mesh 102 in the compressed state are separated, so that the steel bars constituting the steel mesh 102 can slide on the sliding sleeve 201, thereby facilitating multiple adjustments to the size of the steel mesh 102.

[0045] Preferably, a rubber pad 207 is adhered to the upper side of the sliding sleeve 201, and a rubber pad 207 is also adhered to the side wall of the movable plate 203 close to the sliding sleeve 201; the rubber pad 207 is in contact with the steel mesh 102, and the rubber pad 207 can increase the friction between the steel mesh 102 and the sliding sleeve 201. After the size of the steel mesh 102 is fixed, it may be accidentally touched by the construction workers at the assembly site, causing the steel bars to shift. The rubber pad 207 can prevent the steel bars of the steel mesh 102 from moving after being fixed, and can prevent the steel mesh 102 and the sliding sleeve 201 from sliding, which may cause the size of the steel mesh 102 to deviate.

[0046] Preferably, the web reinforcement 103 is formed by bending a whole steel bar, and the bottom of the web reinforcement 103 is welded to the steel mesh 102; the web reinforcement 103 is grouped into two, and each group of web reinforcements 103 has a gap at the top position, and the upper chord steel bar 104 is welded and fixed in the gap between the two web reinforcements 103.

[0047] Preferably, a rectangular mold is placed at the bottom of the bottom mold 105 during casting, so that a rectangular groove is opened at the bottom of the cast bottom mold 105, and the filling plate 106 is fixed in the groove at the bottom of the bottom mold 105.

[0048] Preferably, the diameter of the upper chord steel bar 104 is larger than the diameter of the web bar 103; the lower chord steel bar 101 and the upper chord steel bar 104 have the same diameter, the lower chord steel bar 101 is welded to the middle position of the web bar 103, and the lower chord steel bar 101 and the upper chord steel bar 104 are parallel to each other.

[0049] Preferably, a gap is left between the lower chord reinforcement 101 and the bottom form 105, so that the portion above the lower chord reinforcement is exposed outside the bottom form 105 after the bottom form 105 is cast and formed; the lower chord reinforcement 101 is welded to the outside of the web reinforcement 103, and there are multiple lower chord reinforcements 101, and the lower chord reinforcements 101 are all located at the same height.

[0050] Preferably, there are multiple adjustment components 200, and the adjustment components 200 are all located at the connection of the steel mesh 102; after the steel bars constituting the steel mesh 102 are fixed by the movable plate 203 and the sliding sleeve 201, when the bottom mold 105 is poured, the concrete will impact the adjustment components 200, and the impact may cause some spring pins 204 on the adjustment components 200 to disengage from the grooves on the support rod 202, causing the movable plate 203 to loosen, causing the steel bars of the steel mesh 102 to be moved when the bottom mold 105 is poured. The offset causes the size of the steel mesh 102 to change, which will affect the bearing capacity of the thin-walled plate after pouring. The sliding sleeve 201 and the movable plate 203 are both made of metal. After the size of the steel mesh 102 is adjusted to a suitable position and it is determined that no further adjustment is required, the sliding sleeve 201 and the movable plate 203 are welded to the steel mesh 102 by welding, so that the steel mesh 102 will not be offset due to the loosening of the adjustment component 200 during concrete pouring, thereby ensuring that the bearing capacity of the thin-walled plate is not affected.

[0051] In actual use, the steel truss thin-walled plate with adjustable steel mesh size according to the embodiment of the present application:

[0052] After the size of the steel mesh 102 is determined, the movable plate 203 is pressed downward so that the spring pin 204 on the fixing rod 206 is stuck in the groove inside the support rod 202 to fix the movable plate 203. After determining that the size of the steel mesh 102 does not need to be adjusted, the sliding sleeve 201 and the movable plate 203 are welded to the steel mesh 102, and then the web 103 is welded to the steel mesh 102 and the bottom mold 105 is cast so that the steel mesh 102 is completely buried in the bottom mold 105. Finally, the upper chord steel bar 104 and the lower chord steel bar 101 are welded to the web 103.

A person skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
