Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction column construction, in particular to a connecting structure between a construction column and a floor beam. Background Art
[0002] During the construction of masonry projects in the construction field, in order to enhance the integrity and stability of buildings and walls, reinforced concrete construction columns are usually set and connected to ring beams on each floor to form a space frame capable of resisting bending and shear, which is an effective measure to prevent the collapse of houses. The setting positions of construction columns are usually at the four corners of the exterior wall, the intersection of the transverse wall and the exterior longitudinal wall at the staggered floor part, both sides of larger openings, the intersection of the inner and outer walls of large rooms, etc.
[0003] In some buildings, the top of the construction column often needs to be connected to the floor beam. Therefore, there are mainly two ways for the steel bar construction of the construction column. One way is post-inserted bars, that is, drilling holes at the bottom surface of the already cast floor beam, inserting steel bars, and then injecting high-strength post-inserted bar glue for reinforcement. Using the inserted steel bars as the connection foundation, the main steel bars of the construction column are tied to them. The construction quality of this post-inserted bar method is difficult to control.
[0004] The other way is pre-buried steel bars. At the construction site, not only is it difficult to control the size of the pre-buried steel bars, and the pre-buried position often deviates. During the concrete vibration process, the pre-buried steel bars are easily detached. Moreover, holes need to be opened on the formwork, resulting in difficult formwork removal. Content of the Utility Model
[0005] The purpose of the utility model is to overcome the defects and deficiencies existing in the prior art, and provide a connecting structure between a construction column and a floor beam to ensure the effective connection between the top of the construction column and the floor beam and ensure the construction quality.
[0006] To achieve the above purpose, the utility model provides the following technical solutions:
[0007] A connecting structure between a construction column and a floor beam includes a fixing plate, a bent anchor steel bar, a sleeve and a main construction column steel bar. It is characterized in that: the fixing plate is fixed on the bottom formwork of the floor beam for pouring; the sleeve is fixedly connected to the upper surface of the fixing plate; the lower end of the bent anchor steel bar and the upper end of the main construction column steel bar are respectively fixedly connected to the sleeve. After the floor beam is cast and formed, the bent anchor steel bar and the sleeve are both pre-buried in the floor beam, and the fixing plate is fixed on the bottom surface of the floor beam.
[0008] Further, corresponding screw holes are provided at both ends of the fixing plate and on the bottom formwork of the beam, and screws are screwed into the corresponding screw holes to fix the fixing plate on the bottom formwork of the beam.
[0009] Further, conical through holes with a smaller upper part and a larger lower part are provided at both ends of the fixing plate.
[0010] Further, the sleeve includes an inner sleeve and an outer sleeve. A conical sleeve with a smaller upper end and a larger lower end is fixedly connected to the lower end of the inner sleeve. After the inner sleeve passes through the corresponding through hole from bottom to top, it is threadedly connected to the outer sleeve. The conical sleeve is inserted into the corresponding through hole to fix the sleeve on the upper surface of the fixed plate.
[0011] Further, external threads are provided at the lower end of the bent anchor steel bar and the upper end of the main reinforcement of the structural column, and they are threadedly connected to the inner sleeve.
[0012] Further, there are four bent anchor steel bars, sleeves and main reinforcements of the structural column, and there are two fixed plates, which cross each other in a cross shape or an X shape.

[0022] See Figures 1-5 , a connecting structure between a construction column and a floor beam, which includes a fixing plate 1, a bent anchor steel bar 2, a sleeve 3, and a main reinforcement bar 4 of the construction column. The fixing plate 1 is fixed on the bottom formwork of the floor beam 5 (not shown in the figure) for pouring. The sleeve 3 is fixedly connected to the upper surface of the fixing plate 1. The lower end of the bent anchor steel bar 2 and the upper end of the main reinforcement bar 4 of the construction column are respectively fixedly connected to the sleeve 3. After the floor beam 5 is poured and formed, the bent anchor steel bar 2 and the sleeve 3 are both embedded in the floor beam 5, and the fixing plate 1 is fixed to the bottom surface of the floor beam 5.
[0023] In the present utility model, corresponding screw holes 6 are provided at both ends of the fixing plate 1 and on the bottom formwork of the beam, and screws 7 are screwed into the corresponding screw holes 6 to fix the fixing plate 1 to the bottom formwork of the beam.
[0024] In the present utility model, conical through holes 8 with a smaller upper part and a larger lower part are provided at both ends of the fixing plate 1.
[0025] In the present utility model, the sleeve 3 includes an inner sleeve 31 and an outer sleeve 32. The inner wall and the outer wall of the inner sleeve 31 are both provided with threads, and the inner wall of the outer sleeve 32 is provided with threads. The lower end of the inner sleeve 31 is fixedly connected with a conical sleeve 33 with a smaller upper part and a larger lower part. After the inner sleeve 31 passes through the corresponding through hole 8 from bottom to top, it is threadedly connected to the outer sleeve 31, and the conical sleeve 33 is inserted into the corresponding through hole 8 to fix the sleeve 3 to the upper surface of the fixing plate 1.
[0026] In the present utility model, the lower end of the bent anchor steel bar 2 and the upper end of the main reinforcement bar 4 of the construction column are both provided with external threads and are threadedly connected to the inner sleeve 31, so as to respectively fixedly connect the lower end of the bent anchor steel bar 2 and the upper end of the main reinforcement bar 4 of the construction column to the sleeve 3, thereby connecting the bent anchor steel bar 2 and the main reinforcement bar 4 of the construction column.

[0028] It should be noted that there can also be four fixing plates 1, which cross each other in a cross shape or an X shape.

On the basis of facilitating the control of the spacing of the six main bars 4 of the construction column, this can further ensure the effective connection between the top of the construction column and the floor beam 5.
[0029] The following further describes the present invention with reference to the accompanying drawings:
[0030] During construction, first set up the bottom formwork of the floor beam 5 for pouring. Then, screw the lower end of the bent anchor bar 2 into the inner sleeve 31 from top to bottom to connect the bent anchor bar 2 with the sleeve 3. Then, use adhesive tape to seal the upper port of the sleeve 3 to prevent concrete from pouring into it.
[0031] Next, install the fixing plate 1 on the bottom formwork of the floor beam 5 according to the designed position of the construction column, that is, screw the screw 7 into the corresponding screw hole 6 to fix the fixing plate 1 on the bottom formwork.
[0032] Then, after the inner sleeve 31 passes through the corresponding through hole 8 from bottom to top, screw it into the outer sleeve 31 so that the conical sleeve 33 is inserted into the corresponding through hole 8 to fix the sleeve 3 on the upper surface of the fixing plate 1.
[0033] Then, pour concrete. After the floor beam 5 is poured and formed, the bent anchor bar 2 and the sleeve 3 are both embedded in the floor beam 5, and the fixing plate 1 is fixed on the bottom surface of the floor beam 5.
[0034] After removing the bottom formwork of the beam, use a torque wrench to screw the upper end of the main bar 4 of the construction column into the inner sleeve 31 to connect the main bar 4 of the construction column with the sleeve 3.
[0035] Then, tie steel bars on the main bar 4 of the construction column, set up the formwork for pouring the construction column, and then the construction column can be poured.
