Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of box-type columns, and in particular relates to a box-type column for a building structure. Background Art
[0002] The box column is named because of its shape like a large iron box. It is generally used as a beam or column in steel structures. It has high bearing capacity, good earthquake resistance, simple production, and factory production, which can greatly shorten the construction period. During the construction of steel structure buildings, the upper and lower box columns are usually moved to the top of the lower box columns by a crane, and the connection between the two box columns is fixed by bolts. However, in this process, due to the lack of fixation of the upper box column, it is easy to swing during the connection process, making the bolting work very difficult. Utility Model Content
[0003] In view of the above problems, the purpose of the utility model is to provide a box column for a building structure, which can be preliminarily fixed to the upper box column when the upper box column and the lower box column are connected, thereby facilitating the docking between the upper box column and the lower box column.
[0004] The lockhole that is formed on the upper and lower sides of the frame is formed on the upper and lower sides of the frame, and the lockhole that is formed on the lower and lower sides of the frame is formed on the frame.
[0005] The beneficial effects of the utility model are as follows: when the device is installed, the upper box-type column is hoisted above the lower box-type column, so that the screw plate at the bottom of the upper box-type column is aligned with the screw plate at the top of the lower box-type column, and the insertion block is inserted into the insertion groove. During the insertion process of the insertion block, the limit block is squeezed into the inside of the limit block installation groove. When the insertion block is inserted into place, under the action of the rebound force of the spring, the limit block is inserted into the limit groove on the side of the insertion block, which plays a preliminary fixing role on the upper box-type column and facilitates the docking between the upper box-type column and the lower box-type column.
[0006] Insert the screw plate at the connection between the clamping plate of the external supporting mechanism and the upper box-type column and the lower box-type column into place, align the screw holes on the clamping plate and the screw plate, and make the L-shaped supporting plate contact with the sides of the upper box-type column and the lower box-type column, use the second locking bolt to fix the clamping plate and the screw plate, and then tighten the first locking bolt to fix the upper box-type column and the fixing plate to complete the installation of the connection between the upper box-type column and the lower box-type column. Through the setting of the external supporting mechanism, the upper box-type column and the lower box-type column can be resisted from shear force. When the upper box-type column and the lower box-type column are subjected to shear force from the side, the oblique supporting plate can support the connection between the upper box-type column and the lower box-type column from all directions, and cooperate with the internal reinforcement plate inside the upper box-type column and the lower box-type column to improve the structural strength of the upper box-type column and the lower box-type column.
[0007] To fix the limit block:
[0008] As a further improvement of the above technical solution: a fixing plate is installed at the other end of the push rod.
[0009] The beneficial effect of this improvement is that the fixing plate is used to fix the upper box-type column, thereby playing a role in fixing the limit block.
[0010] In order to pull the limit block out of the limit groove when the upper box column needs to be removed:
[0011] As a further improvement of the above technical solution: the fixing plate is provided with a screw hole and is connected with a first locking bolt, and a pull ring is installed at one end of the first locking bolt.
[0012] The beneficial effects of this improvement are as follows: the first locking bolt is used to fix the fixing plate, and the pull ring is used to pull the limit block out of the limit groove when disassembling the upper box column.
[0013] To fix the limit block:
[0014] As a further improvement of the above technical solution: screw holes are also provided at positions where the sides of the upper box-type columns are aligned with the screw holes on the fixing plate.
[0015] The beneficial effect of this improvement is that through the provision of the screw holes, the fixing plate can be fixed to the upper box-type column by the first locking bolt, thereby fixing the limit block.
[0016] In order to improve the structural strength of the upper box column and the lower box column:
[0017] As a further improvement of the above technical solution: inner reinforcement plates are provided inside the upper box-type column and the lower box-type column.
[0018] The beneficial effect of this improvement is that the inner reinforcement plate is used to improve the structural strength of the upper box column and the lower box column.
[0019] To improve the convenience of docking:
[0020] As a further improvement of the above technical solution: the bottom of the insertion block is provided with a chamfer, and the bottom of the insertion groove fits the chamfer shape of the bottom of the insertion block.
[0021] The beneficial effect of this improvement is that by setting the chamfer, the insertion block can be more conveniently aligned with the insertion slot and inserted, thereby improving the convenience of docking.
[0022] To fix the insert block to the insert slot:
[0023] As a further improvement of the above technical solution: a limiting groove is provided on the side of the insertion block.
[0024] The beneficial effect of this improvement is that a limiting groove is provided on the side of the insertion block, which is used to cooperate with the limiting block for insertion and connection, and fix the insertion block and the insertion groove.
