Technical Field
[0001] The present application relates to the technical field of steel tube concrete pouring, and specifically to a self-compacting concrete steel tube column connecting plate structure. Background Art
[0002] Steel tube concrete refers to a structural component formed by filling concrete in a steel tube, and the steel tube and its core concrete can jointly withstand external loads. According to different cross-sectional shapes, it can be divided into circular steel tube concrete, square and rectangular steel tube concrete, and polygonal steel tube concrete.
[0003] In the prior art, the steel pipe used for concrete pouring is a single pipe column, that is, one end is completely sealed and the other end is provided with a through hole for grouting. Concrete is poured into the steel pipe through the through hole. During the grouting process, the gas inside the steel pipe will be compressed, and only the through hole used for grouting is connected to the outside world. As a result, the internal gas cannot be discharged to the outside world normally, and will be continuously compressed inside the steel pipe. When the gas volume is compressed to a certain extent, its pressure is too high, which will cause the concrete to be unable to continue to be poured. After the pouring is stopped, the original air area is left inside the steel pipe. It is difficult to achieve internal density at one time, and secondary or multiple auxiliary pouring is required, which affects the actual work efficiency. In addition, the non-dense concrete will produce gaps with the inner wall of the steel pipe after solidification and shrinkage, affecting the integrity and actual strength of the structure. In this regard, the present application provides a self-compacting concrete steel pipe column connecting plate structure based on the layout of the structure to solve the above problems. Utility Model Content
[0004] In response to the shortcomings of the existing technology, the present application provides a self-compacting concrete steel pipe column connecting plate structure, which has the advantages of greatly reducing the situation where air bubbles are retained and leading to loose pouring, and can also easily observe the density of concrete pouring. It solves the problem that the concrete pouring in the existing steel pipe concrete column is easily loose due to the retention of gas.
[0005] To achieve the above objectives, the present application provides the following technical solutions: a self-compacting concrete steel pipe column connection plate structure, comprising a rectangular steel pipe column, a connecting assembly for connecting to the outside world is installed on the outside of the rectangular steel pipe column, a connecting bottom plate is fixed to the bottom of the rectangular steel pipe column, and a plurality of folded plates are fixed to the outside of the rectangular steel pipe column;
[0006] The connecting component includes a connecting top plate fixed on the top of the rectangular steel pipe column, a pouring hole opened on the top of the connecting top plate, a plurality of exhaust holes opened on the top of the connecting top plate and evenly distributed outside the pouring hole, and a plurality of overflow channels opened on the outside of the rectangular steel pipe column and connected to its interior.
[0007] By adopting the above technical solution, the situation where bubbles are retained and lead to loose pouring can be greatly reduced, and the density of concrete pouring can be easily observed.
[0008] Furthermore, a plurality of mounting holes are provided on the outer side of the folding plate, and the number of the folding plates is two and they are symmetrically distributed.
[0009] By adopting the above technical solution, it is convenient to pass the connecting piece through the installation hole, so that the folding plate can be installed and fixed.
[0010] Furthermore, the interior of the pouring hole is connected to the interior of the rectangular steel pipe column, and the number of the exhaust holes is four.
[0011] By adopting the above technical solution, the pouring work of concrete can be carried out through the pouring holes.
[0012] Furthermore, the interior of the exhaust hole is connected to the interior of the rectangular steel pipe column, the inner side of the exhaust hole is circular, and the inner diameter of the exhaust hole is not greater than three centimeters.
[0013] By adopting the above technical solution, the gas inside the rectangular steel pipe column can be discharged to the outside through the exhaust hole, so that the internal air pressure will not be too high and it can also play a certain limiting role on the concrete.
[0014] Furthermore, the number of the overflow channels is four and they are symmetrically distributed on the left and right, and the two overflow channels on the same side are respectively located at the top and bottom of the folding plate on the same side.
[0015] By adopting the above technical solution, the overflow channels at the top and bottom can both play a role in assisting exhaust.
[0016] Furthermore, the overflow channel consists of an inner groove, a connecting cavity and an outer groove; and the inner diameters of the inner groove, the connecting cavity and the outer groove are equal.
[0017] By adopting the above technical solution, gas and concrete can be stably discharged through the overflow channel.
[0018] Furthermore, the inner groove is opened on the inner side of the rectangular steel pipe column and is located at the bottom of the corresponding outer groove, and the outer groove is opened on the outer side of the rectangular steel pipe column.
[0019] By adopting the above technical solution, the internal concrete can enter the inner side of the inner groove.
[0020] Furthermore, the communication cavity is opened inside the rectangular steel pipe column and is used to connect the interiors of the corresponding inner groove and outer groove.
[0021] By adopting the above technical solution, the concrete inside the inner side can enter the inner part of the outer groove through the connecting cavity.
[0022] Compared with the existing technology, the technical solution of this application has the following beneficial effects:
[0023] The self-compacting concrete steel pipe column connecting plate structure, through the use of connecting components on the outside of the rectangular steel pipe column, can greatly reduce the situation where bubbles are retained and cause loose pouring, and can also easily observe the density of the concrete pouring. By utilizing the layout of the structure, the internal gas can be effectively discharged during the pouring process, so that the internal air will not be excessively compressed, thereby avoiding the occurrence of pouring problems. At the same time, by utilizing the fluidity and viscosity of concrete, after the internal gas is completely discharged, the pressure during continued pouring can press out the concrete, making it easier for external staff to judge whether the pouring is in place, which not only improves work efficiency, but also improves work quality, and is very practical.

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0029] See also Figures 1 to 3The present application provides a technical solution: a self-compacting concrete steel pipe column connecting plate structure, comprising a rectangular steel pipe column 1, a connecting component 200 for connecting to the outside world is installed on the outside of the rectangular steel pipe column 1, a connecting bottom plate 3 is fixed to the bottom of the rectangular steel pipe column 1, and a plurality of folding plates 4 are fixed to the outside of the rectangular steel pipe column 1; by using the connecting component 200 on the outside of the rectangular steel pipe column 1, the situation of loose pouring caused by air bubble retention can be greatly reduced, and the density of concrete pouring can be conveniently observed. By utilizing the layout of the structure, the internal gas can be effectively discharged during the pouring process, so that the internal air will not be excessively compressed, thereby avoiding the occurrence of the situation where pouring cannot be carried out. At the same time, by utilizing the fluidity and viscosity of the concrete, after the internal gas is completely discharged, the pressure during continued pouring can press out the concrete, so that it is convenient for the staff on the outside to judge whether the pouring is in place, which not only improves the work efficiency, but also improves the work quality, and is very practical.
[0030] It should be noted that a plurality of mounting holes are provided on the outer side of the folding plate 4. There are two folding plates 4 and they are symmetrically distributed. The folding plates 4 and the mounting holes on the outer side can facilitate the insertion and installation of the connectors.
[0031] In this embodiment, the connecting component 200 is a structure used to connect the interior of the rectangular steel pipe column 1 with the outside to a certain extent.
[0032] like Figure 1 、 Figure 2 and Figure 3 As shown, the connecting component 200 includes a connecting top plate 201 fixed on the top of the rectangular steel pipe column 1, a pouring hole 202 opened on the top of the connecting top plate 201, a plurality of exhaust holes 203 opened on the top of the connecting top plate 201 and evenly distributed on the outside of the pouring hole 202, and a plurality of overflow channels 204 opened on the outside of the rectangular steel pipe column 1 and connected to its interior.
[0033] It should be noted that the interior of the pouring hole 202 is connected to the interior of the rectangular steel pipe column 1, so that the concrete pouring work can be carried out through the pouring hole 202. There are four exhaust holes 203, and the interior of the exhaust holes 203 is connected to the interior of the rectangular steel pipe column 1, so that the gas inside the rectangular steel pipe column 1 can be discharged to the outside through the exhaust holes 203, so that the internal air pressure will not be too high.
[0034] In addition, the inner side of the exhaust hole 203 is circular, and the inner diameter of the exhaust hole 203 is no more than three centimeters. Specifically, the inner diameter of the exhaust hole 203 is 1.5 centimeters, so that the internal gas can be discharged normally while also having a certain restrictive effect on the concrete, so that the pressurized concrete can be discharged through the overflow channel 204, ensuring the internal density.
[0035] In addition, there are four overflow channels 204 and they are symmetrically distributed on the left and right, and the two overflow channels 204 on the same side are respectively located at the top and bottom of the folding plate 4 on the same side, so that the overflow channels 204 at the top and bottom can both play the role of auxiliary exhaust, so that the pouring work of the front section can be carried out efficiently, and after the liquid level of the concrete exceeds the bottom overflow channel 204, the pouring work of the rear section can be slowed down, so that the air inside the rectangular steel pipe column 1 close to the side connecting the top plate 201 can be discharged stably, avoiding the retention of bubbles.
[0036] At the same time, the overflow channel 204 is composed of an inner groove, a connecting cavity and an outer groove; and the inner diameters of the inner groove, the connecting cavity and the outer groove are equal. The inner groove is opened on the inner side of the rectangular steel pipe column 1 and is located at the bottom of the corresponding outer groove. The outer groove is opened on the outside of the rectangular steel pipe column 1. The connecting cavity is opened inside the rectangular steel pipe column 1 and is used to connect the interiors of the corresponding inner groove and outer groove, so that the overflow channel 204 can form a curved channel, and the concrete inside will need to enter the interior of the inner groove first, and then through the continuous action of the pouring pressure, the concrete inside the inner groove will be pushed upward to the interior of the connecting cavity, and finally discharged through the outer groove. The principle is to utilize the fluidity and viscosity of concrete and the limitation of the hole. When the pressure is not large, concrete with a certain viscosity cannot be pushed out of the hole. Therefore, when the concrete is discharged from the overflow channel 204, it can be concluded that the concrete pressure inside the rectangular steel pipe column 1 is already in an overflowing state, which can ensure the density of the internal pouring.
[0037] The working principle of the above embodiment is:
[0038] When pouring the concrete steel pipe column, the pipe of the pouring equipment is connected to the pouring hole 202 on the connecting top plate 201, and the pouring work can be carried out. During the concrete pouring process, the gas inside the rectangular steel pipe column 1 will be discharged to the outside through the exhaust hole 203 and the overflow channel 204. When the liquid level of the concrete exceeds the overflow channel 204, the gas is discharged through the exhaust hole 203. Due to the fluidity and viscosity of the concrete, the concrete inside the overflow channel 204 will not flow out directly. When the concrete is poured densely, the concrete will first be discharged through the exhaust hole 203. Due to the limitation of the aperture of the exhaust hole 203, the discharge of the internal concrete will be restricted. Therefore, under the continuous action of pressure, the concrete will be discharged to the outside through the overflow channel 204. At this time, it can be observed by the staff outside, and the pouring of the rectangular steel pipe column 1 can be completed.
[0039] Compared with the existing technology, the self-compacting concrete steel pipe column connecting plate structure, through the use of the connecting component 200 on the outside of the rectangular steel pipe column 1, can greatly reduce the situation where the air bubbles are retained and cause the pouring to be not dense, and can also conveniently observe the density of the concrete pouring. By utilizing the layout of the structure, the internal gas can be effectively discharged during the pouring process, so that the internal air will not be excessively compressed, thereby avoiding the occurrence of the pouring failure. At the same time, by utilizing the fluidity and viscosity of the concrete, after the internal gas is completely discharged, the pressure during the continued pouring can press out the concrete, making it easier for the outside staff to judge whether the pouring is in place. It not only improves the work efficiency, but also improves the work quality. It is very practical and solves the problem that the concrete pouring in the existing steel pipe concrete column is easily not dense due to the retention of gas.
