Description

TECHNICAL FIELD

[0001] The present application relates to the field of modern building high-rise large-span corridor engineering, and particularly relates to an adjustable assembly type steel connecting fixing device for a main steel beam at the lower part of a large-span corridor. BACKGROUND

[0002] With the continuous development of modern building engineering, people's functional requirements for residential buildings are continuously improved. The main role of the modern residential corridor is to effectively evacuate personnel through the corridor in the case that the stairway or other escape routes cannot be evacuated in time. Due to the high height of the corridor and the lack of support structure at the lower part, the construction of the high-altitude corridor is difficult. At present, the main construction method is to set up a main steel beam and a secondary steel beam at the lower part of the corridor to build an operation platform. The main steel beam has the characteristics of fixed length and non-adjustment, and cannot be adjusted according to different corridor spans, but can only be welded and lengthened for use according to the fixed-span corridor. SUMMARY

[0003] In order to improve the efficiency of the operation platform and solve the problem that the main steel beam cannot be adjusted according to different corridor spans, but can only be welded and lengthened for use according to the fixed-span corridor,

[0004] The utility model provides a kind of adjustable assembly type steel connecting fixing device.

[0005] To achieve the above object, the present application provides the following technical scheme:

[0006] An adjustable assembly type steel connecting fixing device, characterized in that: it comprises an upper top plate, a left concave clamping plate, a right side plate, a lower bottom plate, a middle main steel beam and an end main steel beam. The left side edge of the upper top plate is vertically welded with the top edge of the left concave clamping plate. The right side edge of the upper top plate is vertically welded with the top edge of the right side plate. The bottom edge of the left concave clamping plate is vertically welded with the left edge of the lower bottom plate. The bottom edge of the right side plate is vertically welded with the right edge of the lower bottom plate. The upper top plate, the left concave clamping plate, the right side plate and the lower bottom plate form a tetrahedral frame. One end of the middle main steel beam is inserted into one end of the tetrahedral frame and fixed with the upper top plate by bolts. One end of the end main steel beam is inserted into the other end of the tetrahedral frame and fixed with the upper top plate by bolts.

[0007] The present application can flexibly adjust the length of the main steel beam according to different span corridors, achieving the characteristics of one-time investment and multiple utilization of the operation platform. The disassembly and assembly operation is simple, and the construction efficiency is high.

[0008] Further, a groove with a scale is provided in the middle of the left concave clamping plate, which can control the depth of insertion of the middle main steel beam and the end main steel beam.

[0009] Further, a circular level is arranged in the middle of the upper top plate for detecting the level of the integral reinforcing device, and when the bottom plate is kept horizontal, the bubble in the circular level is kept in the center of the circular level.

[0010] The construction method of the present application: when in use, the upper top plate, the left concave clamping plate, the right side plate and the lower bottom plate are welded to form a tetrahedron frame. Then, one end of the middle main steel beam is slowly inserted into the tetrahedron frame, and when inserted, the scale ruler in the middle of the left concave clamping plate is observed to determine the insertion depth of the middle main steel beam at any time. When the insertion depth reaches the predetermined position, the top bolt hole and the bottom bolt hole of the middle main steel beam should be consistent with the bolt hole positions of the upper top plate and the lower bottom plate of the integral reinforcing device, and then high-strength bolts are inserted into the aligned bolt holes to fix the integral reinforcing device and the middle main steel beam.

[0011] By the same method, one end of the end main steel beam is slowly inserted into the tetrahedron frame, and when inserted, the scale ruler in the middle of the left concave clamping plate is observed to determine the insertion depth of the end main steel beam at any time. When the insertion depth reaches the predetermined position, the top bolt hole and the bottom bolt hole of the end main steel beam should be consistent with the bolt hole positions of the upper top plate and the lower bottom plate, and then high-strength bolts are inserted into the aligned bolt holes to fix the end main steel beam. For different span corridors, different lengths of end main steel beams are used, which can conveniently and quickly adjust the length of the main steel beam to adapt to the construction needs of different span corridors.

[0012] After the connection of the middle main steel beam and the end main steel beam through the tetrahedron frame is completed, the main steel beam is hoisted to the floor structure installation position by the tower crane as a whole, and when installed, the horizontal position of the main steel beam is adjusted by observing the level bubble in the circular level of the upper top plate. When the level bubble is in the center of the circular level, the main steel beam is in a horizontal state. In addition, the level bubble in the circular level of the upper top plate can be observed at any time during the installation of the upper frame body and the construction of the corridor to determine whether the main steel beam is deformed, which plays a monitoring role in the deformation of the main steel beam to improve the safety of the corridor construction process.

[0013] The present application can quickly lengthen the main steel beam, and can flexibly adjust the length of the main steel beam according to different span corridors, so as to achieve the characteristics of one-time investment and multiple utilization of the operation platform.

[0022] In use, the middle main steel beam 5 and the end main steel beam 6 are inserted into the tetrahedron frame, and the middle main steel beam 5 and the end main steel beam 6 are fixed with the tetrahedron frame through the high-strength bolt 7.

[0023] Construction method of the present application:

[0024] In use, the upper top plate 1, the left concave clamping plate 2, the right side plate 3, and the lower bottom plate 4 are welded to form a tetrahedron frame. Then, one end of the middle main steel beam 5 is slowly inserted into the tetrahedron frame. When inserting, the scale ruler 9 in the middle of the left concave clamping plate 2 is observed to determine the insertion depth of the middle main steel beam 5 at any time. When the insertion depth reaches a predetermined position, the top bolt hole and the bottom bolt hole of the middle main steel beam 5 should be consistent with the positions of the bolt holes of the upper top plate 1 and the lower bottom plate 4 of the overall reinforcing device. Then, the high-strength bolt 7 is inserted into the aligned bolt holes 8 to fix the overall reinforcing device and the middle main steel beam 5.

[0025] In the same way, one end of the end main steel beam 6 is slowly inserted into the tetrahedron frame, and when the insertion is in progress, the scale 9 in the middle of the left concave clamping plate 2 is observed to determine the insertion depth of the end main steel beam 6 at any time. When the insertion depth reaches the predetermined position, the bolt holes at the top and bottom of the end main steel beam 6 should be aligned with the bolt hole positions of the upper top plate 1 and the lower bottom plate 4 of the integral reinforcing device, and then the high-strength bolt 7 is inserted into the aligned bolt hole 8 to fix the integral reinforcing device and the end main steel beam 6. For different span corridors, different lengths of end main steel beams are used, and the length of the main steel beam can be adjusted conveniently and quickly to adapt to the construction needs of different span corridors.

In addition, the level bubble in the circular level of the upper top plate of the integral reinforcing device can be observed at any time during the installation of the upper frame body and the construction of the corridor to determine whether the main steel beam is deformed, and the deformation of the main steel beam is monitored to improve the safety of the corridor construction process.

[0027] The present application can flexibly adjust the length of the main steel beam according to different span corridors, so that the operation platform can be used multiple times after being used once, and the disassembly and assembly operation is simple and the construction efficiency is high.
