Description

Technical Field

[0001] The utility model relates to the technical field of truss steel bar stacking devices, in particular to a truss steel bar stacking device. Background Technique

[0002] In the construction engineering industry, prefabricated buildings are developing at an unprecedented speed. Especially for laminated slabs, a large amount of formwork erection can be avoided on site by processing in the factory, and the appearance effect of the surface can also be improved. A large number of truss steel bars are required for processing laminated slabs in the factory.

[0003] At the present stage, the storage method of truss steel bars is to use wooden strips for padding or simply not use any materials for padding. This will cause wear and tear of truss steel bars during storage and transportation. Moreover, due to the increase in stacking height, the stacking stability of truss bars is poor, and it is easy to collapse due to inclination, resulting in low safety. Therefore, a truss steel bar stacking device is designed to solve the above problems. Content of the Utility Model

[0004] Aiming at the defects in the prior art, the utility model provides a truss steel bar stacking device, which can avoid the instability of truss steel bar stacking, prevent the phenomenon of inclination and collapse, and has high practicability.

[0005] In order to solve the above technical problems, the utility model proposes the following technical solutions:

[0006] A truss steel bar stacking device includes a bottom frame, columns, protective crossbars and pin shafts. Columns are fixedly arranged at four corners of the upper surface of the bottom frame. Embedding grooves are opened above the columns. Protective crossbars are rotatably arranged in the inner embedding grooves through pin shafts. Positioning bolts are threadedly connected to the tops of the outer columns.

[0007] Further, the length of the protective crossbar is greater than the width of the bottom frame, and when the protective crossbar is embedded in the outer embedding groove, the horizontal height of the upper surface is equal to the horizontal height of the upper surface of the positioning bolt.

[0008] Further, the length of the positioning bolt is equal to the thickness of the column.

[0009] Further, rubber pads are fixedly arranged on the surface of the column facing the inside of the bottom frame and the upper surface of the bottom frame through fixing glue.

[0010] Further, an opening groove is opened in the center of the inner surface of the bottom frame. A connecting block is fixedly arranged in the center of the outer surface of the bottom frame. An installation groove is opened on the outer side of the upper surface of the connecting block. Springs are fixedly arranged on both sides of the bottom of the installation groove. Embedding blocks are fixedly arranged on the upper surfaces of the springs.

[0011] Further, the connecting block matches the opening groove.

[0012] Further, the upper surface of the embedding block is in the shape of a right trapezoid with a higher horizontal height on the side close to the bottom frame and a lower horizontal height on the side away from the bottom frame.

[0013] Further, when the spring is in the natural elongation state, the side with the lower horizontal height of the embedding block is completely embedded in the installation groove.

[0014] Further, supporting blocks are fixedly arranged at the four corners of the bottom surface of the bottom frame.

[0015] From the above technical solutions, the beneficial effects of the present utility model are as follows:

[0016] 1. In the present utility model, the protective crossbar is rotated along the pin shaft towards the outside of the bottom frame, and then the truss steel bars are horizontally stacked on the bottom frame, and the truss steel bars are located between the inner and outer columns. After the truss steel bars are stacked full, the protective crossbar is rotated again so that the protective crossbar is embedded in the embedding groove on the outer column to complete the stacking. The truss steel bars are wrapped and fixed by the bottom frame, columns and protective crossbar, which can avoid the inclination and collapse of the truss steel bars during stacking, ensure the stable storage of the truss bars, and prevent the truss steel bars from jumping out from above the columns due to vibration during the transportation of the truss steel bars, ensuring the stability during the transportation of the truss steel bars. Moreover, rubber pads are provided on the upper surface of the bottom frame and the surface of the column facing the inside of the bottom frame, which can prevent the truss steel bars from colliding with the device and reduce wear.

[0017] 2. In the present utility model, by providing a connecting block, during the stacking process, the connecting block on one device is inserted into the opening groove on another device. The embedding block on the connecting block will be embedded in the embedding groove under the action of the insertion force. After the connecting block is completely inserted into the opening groove, the elastic force of the spring can pop the embedding block out of the embedding groove, ensuring the connection of two or more devices by the connecting block, so that in case the truss steel bars are too long, the device can stably stack the truss steel bars and is more stable during transportation.

[0029] Hereinafter, embodiments of the technical solution of this utility model will be described in detail with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solution of this utility model more clearly, so they are only examples and cannot be used to limit the protection scope of this utility model.

[0030] Refer to Figure 1-8 : A device for stacking truss steel bars, including a bottom frame 1, vertical columns 2, protective crossbars 3 and pin shafts 301. Vertical columns 2 are fixedly arranged at the four corners of the upper surface of the bottom frame 1. Embedding grooves 201 are provided above the vertical columns 2. Protective crossbars 3 are rotatably arranged in the inner embedding grooves 201 through pin shafts 301. Positioning bolts 202 are threadedly connected to the tops of the outer vertical columns 2.

[0031] During actual use, the protective crossbar 3 is rotated along the pin shaft 301 towards the outside of the bottom frame 1, and then the truss steel bars are horizontally stacked on the bottom frame 1, and the truss steel bars are located between the inner and outer columns 2. After the truss steel bars are fully stacked, the protective crossbar 3 is rotated again so that the protective crossbar 3 is embedded in the embedding groove 201 on the outer column 2, completing the stacking. The truss steel bars can be wrapped and fixed by the bottom frame 1, the columns 2 and the protective crossbar 3, which can avoid the phenomena of inclination and collapse of the truss steel bars during stacking, ensure the stable storage of the truss bars, and prevent the truss steel bars from jumping out from above the column 2 due to vibration during the transportation of the truss steel bars, ensuring the stability during the transportation of the truss steel bars. Moreover, rubber pads are provided on the upper surface of the bottom frame 1 and on the side surface of the column 2 facing the inside of the bottom frame 1, which can prevent the truss steel bars from colliding with the device and reduce wear.

[0032] In this embodiment, the length of the protective crossbar 3 is greater than the width of the bottom frame 1, and when the protective crossbar 3 is embedded in the outer embedding groove 201, the horizontal height of the upper surface is equal to the horizontal height of the upper surface of the positioning bolt 202, which is convenient for the positioning bolt 202 to block the protective crossbar 3 and achieve the effect of positioning the protective crossbar 3.

[0033] In this embodiment, the length of the positioning bolt 202 is equal to the thickness of the column 2, which is convenient for the positioning bolt 202 to extend into the embedding groove 201 to position the protective crossbar 3.

[0034] In this embodiment, rubber pads are fixedly arranged on the surface of the column 2 facing the inside of the bottom frame 1 and on the upper surface of the bottom frame 1 through fixing glue to prevent the truss steel bars from colliding with the device and reduce wear.

[0035] In this embodiment, an opening groove 4 is provided in the center of the inner surface of the bottom frame 1, a connecting block 5 is fixedly arranged in the center of the outer surface of the bottom frame 1, an installation groove 501 is provided on the outer side of the upper surface of the connecting block 5, and spring 502 is fixedly arranged on both sides of the bottom of the installation groove 501, and an embedding block 503 is fixedly arranged on the upper surface of the spring 502.

[0036] In this embodiment, the connecting block 5 matches the opening groove 4.

[0037] In this embodiment, the upper surface of the embedding block 503 is in the shape of a right trapezoid with the horizontal height on the side close to the bottom frame 1 being high and the horizontal height on the side far from the bottom frame 1 being low.

[0038] In this embodiment, when the spring 502 is in the natural elongation state, the side with the lower horizontal height of the embedding block 503 is completely embedded in the installation groove 501, which is convenient for the embedding block 503 to be installed in the installation groove 501 when the connecting block 5 is inserted into the opening groove 4.

[0039] By providing the connecting block 5, during the stacking process, the connecting block 5 on one device is inserted into the opening groove 4 on another device. Under the action of the insertion force, the embedding block 503 on the connecting block 5 will be embedded into the installation groove 501. After the connecting block 5 is completely inserted into the opening groove 4, the elastic force of the spring 502 can eject the embedding block 503 from the installation groove 501, ensuring that the connecting block 5 connects two or more devices. This is convenient for the truss reinforcement to be too long, enabling the device to stack the truss reinforcement stably and be more stable during transportation.

[0040] In this embodiment, supporting blocks 101 are fixedly provided at the four corners of the bottom surface of the bottom frame 1, so that there is a distance between the bottom frame 1 and the ground, facilitating the forklift to fork and transport the device.
