[0033] Please refer to Figs. 1 to 4 The super-thick raft steel support structure provided in the embodiments of the present application includes a plurality of rows of support units arranged opposite to each other, the support unit includes a plurality of column pipes 1 arranged in sequence and spaced apart in the same direction, a cross bar 2 is arranged between the top of two adjacent column pipes 1, and the two ends of the cross bar 2 and the two column pipes 1 are respectively connected through a socket structure to form a detachable connection, and a plurality of inclined rods 4 are further included, the inclined rods 4 are used to connect between the column pipes 1 of two adjacent rows of support units.
[0034] In the present application, a plurality of column pipes 1 are arranged in sequence at intervals in the same direction, a cross bar 2 is connected between the top portions of two adjacent column pipes 1 in a socket manner, thereby forming a support unit, a plurality of support units are arranged in rows, the column pipes 1 of two adjacent rows of support units are connected by inclined rods 4, thereby forming the entire steel reinforcement support. In use, the steel reinforcement support is erected on the lower steel mesh, and then the upper steel mesh can be constructed on the steel reinforcement support.
[0035] Since the steel reinforcement support is designed in a socket type assembly manner, the amount of welding on site is reduced, the steel reinforcement support can be quickly installed and fixed, the on-site construction operation time is greatly shortened, the operation is convenient and fast, the construction efficiency is improved, the socket type assembly operation reduces the on-site welding operation, the construction quality is easy to control, the safety risk is reduced, the cost is saved, the emission of welding fume on site is reduced, and the environmental protection requirements of the construction site are met.
[0036] According to some embodiments of the present application, the socket structure comprises a socket opening 11 formed in the side surface of the top end of the column pipe 1, the width of the socket opening 11 is adapted to the cross bar 2, and two end head plates 21 are arranged at the end portions of the cross bar 2, the size of the end head plate 21 is greater than the width of the socket opening 11. Specifically, the socket opening 11 in the side surface of the column pipe 1 is rectangular, and extends downward from the top end surface of the column pipe 1, that is, forms a flat-bottomed U-shaped notch. Since the column pipe 1 is connected to the cross bar 2 on both sides, the socket opening 11 is arranged on the opposite two side surfaces of the column pipe 1.
[0037] The cross bar 2 and the two end head plates 21 are welded as a whole in a prefabrication factory, when assembled on site, the end portions of the cross bar 2 are placed into the socket openings 11 in the side surfaces of the column pipes 1, and the end head plates 21 are located inside the column pipes 1, since the size of the end head plate 21 is greater than the width of the socket opening 11, that is, the entire cross bar 2 can only be clamped into the socket openings 11 of the adjacent two column pipes 1 from the top end of the column pipe 1 downward, and the end head plate 21 and the inner wall of the column pipe 1 can form a limit, thereby limiting the axial displacement of the cross bar 2.
[0038] According to some embodiments of the present application, the side surface of the column pipe 1 and the end head plate 21 are anchored and connected by a rivet 3. By using this connection method, not only can the cross bar 2 and the column pipe 1 be stably connected, but also the on-site assembly operation of the steel reinforcement support is facilitated, and the erection efficiency of the support is improved.
[0039] According to some embodiments of the present application, the side of the column pipe 1 is provided with a plurality of first riveting holes 12 along the depth direction of the socket 11, and the end plate 21 is correspondingly provided with a plurality of second riveting holes 22, and the rivet 3 is inserted into the first riveting hole 12 and the second riveting hole 22. Since the depth direction of the socket 11 is the height direction of the column pipe 1, the first riveting hole 12 and the second riveting hole 22 are arranged in multiple along this direction, so that the first riveting hole 12 and the second riveting hole 22 at different positions can be selected to cooperate to realize riveting, so as to adjust the fixed position according to the actual height requirement of the cross bar 2. Since the cross bar 2 is installed in a socket type and fixed by the rivet 3, not only the amount of welding on site is reduced, but also the height of the steel support can be easily adjusted, which is safe and accurate, firm and fixed, and the construction quality is good, effectively ensuring the stability and flatness of the steel support.
[0040] According to some embodiments of the present application, the side of the column pipe 1 is provided with a plurality of first riveting holes 12 along the depth direction of the socket 11, and the end plate 21 is correspondingly provided with a plurality of second riveting holes 22, and the rivet 3 is inserted into the first riveting hole 12 and the second riveting hole 22. Since the depth direction of the socket 11 is the height direction of the column pipe 1, the first riveting hole 12 and the second riveting hole 22 are arranged in multiple along this direction, so that the first riveting hole 12 and the second riveting hole 22 at different positions can be selected to cooperate to realize riveting, so as to adjust the fixed position according to the actual height requirement of the cross bar 2. Since the cross bar 2 is installed in a socket type and fixed by the rivet 3, not only the amount of welding on site is reduced, but also the height of the steel support can be easily adjusted, which is safe and accurate, firm and fixed, and the construction quality is good, effectively ensuring the stability and flatness of the steel support.
[0041] It should be noted that when the cross bar 2 is installed and fixed, due to the limiting effect of the socket 11 on the side of the cross bar 2, at least one rivet 3 is used to insert into the first riveting hole 12 and the second riveting hole 22 for fixation, so as to limit the displacement of the cross bar 2 in the height direction of the column pipe 1, and of course multiple rivets 3 can be used for fixation according to requirements.
[0042] According to some embodiments of the present application, the depth of the socket 11 is greater than the size of the cross bar 2 in this direction. Since the depth direction of the socket 11 is the height direction of the column pipe 1, the above design can make the cross bar 2 have a certain adjustment space in the height direction of the column pipe 1 in the socket 11, and the top of the cross bar 2 can not be higher than the top end of the column pipe 1.
[0043] According to some embodiments of the present application, the shapes of the first riveting hole 12 and the second riveting hole 22 are any one of circular, square, rectangular and triangular. Specifically, the rivet 3 can adopt a shape suitable for the riveting hole, or can adopt a wedge shape, and of course can directly adopt a round steel bar, as long as it can be inserted into the first riveting hole 12 and the second riveting hole 22 and limit the relative displacement of the two, which can meet the requirements.
[0044] According to some embodiments of the present application, two reinforcing plates 13 are arranged in the column pipe 1 opposite the socket 11, and the distance between the reinforcing plates 13 and the inner wall of the column pipe 1 is adapted to the thickness of the end plate 21. Specifically, the reinforcing plates 13 are welded to the two sides of the column pipe 1 where no socket 11 is arranged (the welding can be completed in the factory).
[0045] Since the socket 11 is arranged on the side of the top of the column pipe 1, the strength of the column pipe 1 is affected, and the two reinforcing plates 13 can compensate for the above-mentioned effect. Moreover, the distance between the reinforcing plates 13 and the inner wall of the column pipe 1 is adapted to the thickness of the end plate 21, so that when the cross bar 2 is inserted into the socket, the end plate 21 is inserted between the reinforcing plates 13 and the inner wall of the column pipe 1, thereby limiting the two sides of the end plate 21, which facilitates the subsequent installation of the rivet 3.
[0046] According to some embodiments of the present application, the reinforcing plates 13 extend downward from the top end of the column pipe 1 and have a size adapted to the depth of the socket 11. This arrangement can better compensate for the effect of the socket 11 on the top side of the column pipe 1.
[0047] According to some embodiments of the present application, the inclined bars 4 are arranged at intervals between the column pipes 1 of two adjacent rows of support units. Specifically, the column pipes 1 of the two rows of support units are opposite to each other, and the inclined bars 4 can be arranged in a one-in-one-out manner. In order to facilitate the standardized prefabrication and transportation of the column pipes 1 and the cross bars 2, the inclined bars 4 can be welded on site. The inclined bars 4 can be made of round pipes, and in order to facilitate the fixation of the inclined bars 4, overlapping plates (prefabricated by welding in the factory) can be arranged at the two ends of the inclined bars 4, which facilitates the welding and fixation of the two ends of the inclined bars 4 to the side of the column pipe 1.
[0048] Specifically, for a raft with a reinforcement thickness of more than 1.8m, the above-mentioned reinforcement support structure is used to support the double-layer reinforcement mesh. The column pipe 1 in the reinforcement support structure is a 150*150*20mm square pipe, a rectangular socket 11 is arranged at the top end of the side of the column pipe 1 for the cross bar 2 to be inserted, and a rectangular first rivet hole 12 is arranged on both sides of the socket 11. The cross bar 2 is a 65*100*10mm square pipe, and a 100*100*10mm end plate 21 is welded at the end of the cross bar 2 for quick insertion connection, and a rectangular second rivet hole 22 is arranged on the end plate 21. A 10*30*40mm wedge-shaped steel rivet 3 is used to fix the cross bar 2 and the column pipe 1 firmly, which reduces the amount of welding compared with the traditional welding connection and facilitates quick installation and height adjustment.
[0049] The above specific embodiments explain the purpose, technical scheme and beneficial effects of the present application in further detail. It should be understood that the above description is only a specific embodiment of the present application and is not intended to limit the scope of protection of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
