Description

Technical Field

[0001] The present invention relates to the technical field of double X-pillars, and in particular to a temporary support device for installing double X-pillars. Background Art

[0002] In recent years, double X steel tube concrete column structures have been widely used in the design of domestic thermal power buildings. This type of structure forms a spatial grid system by welding double X-shaped steel pipes, and the interior is filled with concrete to enhance the bearing capacity. This design has the advantages of excellent mechanical properties, strong seismic resistance, and high durability. However, with the expansion of the scale of construction, the technical complexity of double X steel tube concrete columns has increased significantly. In current typical domestic projects, the height of a single double X column generally exceeds 30 meters, and the pipe wall thickness is more than 18 mm with a diameter of more than 1.3 meters. The weight of the overall double X after welding a unit reaches more than 50 tons. The hoisting and temporary fixation of such giant components have become key difficulties in construction.

[0003] In the prior art, multi-point independent steel frame support or cable wind rope auxiliary fixation is mostly used, but there are the following defects: insufficient lateral support force, resulting in wind load or lifting disturbance easily causing unit offset, and repeated adjustment of positioning is required. After the construction is completed, due to the large height of the double X-columns, it is inconvenient to disassemble the support columns and construction is inconvenient. Summary of the invention

[0004] In order to remedy the above deficiencies, the present invention provides a temporary support device for double X-column installation that overcomes the above technical problems or at least partially solves the above problems.

[0005] The present invention is achieved in that: The present invention provides a temporary support device for installing double X-columns, comprising an annular foundation, double X-columns and a support mechanism, wherein a pier is cast on the surface of the annular foundation, the double X-columns are installed on the surface of the pier, an integral steel ring beam is connected to the surface of the double X-columns, and the support mechanism is installed on the right part of the annular foundation for temporarily supporting the double X-columns, and the support mechanism comprises: A temporary supporting foundation, which is cast on the right part of the annular foundation, wherein a connecting piece is pre-buried in the inner cavity of the temporary supporting foundation, and a first connecting plate is fixedly mounted on the surface of the connecting piece; A short support column, wherein the short support column is symmetrically installed on two of the temporary support base surfaces, and one end of the short support column is hinged to the double X column; A long support column is installed on one of the temporary support base surfaces, and one end of the long support column is hinged to the double X column.

[0006] In a preferred solution, the double X-column surfaces intersect to form a first intersection and a second intersection, a second connecting plate is fixedly installed at the bottom of the short support column, a bolt is connected between the second connecting plate and the first connecting plate, a first connecting ear is fixedly installed on the surface of the short support column, a first connecting block is fixedly installed on the side wall of the first intersection, and a pin is rotatably installed between the first connecting ear and the first connecting block.

[0007] In a preferred solution, a third connecting plate is fixedly installed at the bottom of the long support column, and bolts are connected between the third connecting plate and the first connecting plate.

[0008] In a preferred solution, a connecting seat is fixedly mounted on the surface of the long support column, a second connecting ear is fixedly mounted on the surface of the connecting seat, a second connecting block is fixedly mounted on the side wall of the second intersection, and the second connecting block is hinged to the second connecting ear.

[0009] By setting up a support mechanism, two groups of supports are adopted, a long support column plus a group of short support columns, which is relatively safe and simple. The long support column serves as the main load-bearing structure and bears more than 70% of the vertical load; the double-support short support column shares the remaining vertical load through the first intersection and absorbs horizontal forces such as wind load and lifting swing force, forming a "main-auxiliary coordinated" force mechanism to avoid the risk of overloading of a single support, and the two fulcrums of the short support column diffuse the local stress to the adjacent pipe sections, reducing the stress concentration factor and increasing the stability of the device.

[0010] In a preferred solution, a transverse pulling mechanism is installed on the surface of the temporary support base for providing transverse supporting force, and the transverse pulling mechanism includes a reinforcing column, a fourth connecting plate and a transverse tie rod. The reinforcing column is welded to the side of the connecting piece, and the fourth connecting plate is fixedly installed on one end of the reinforcing column. A third connecting block is fixedly installed on the surface of the fourth connecting plate, and a transverse tie rod is installed between two adjacent fourth connecting plates. Third connecting ears are fixedly installed on both ends of the transverse tie rod, and a pin shaft is installed between the third connecting ear and the third connecting block.

[0011] In a preferred embodiment, a bidirectional screw is rotatably installed in the inner cavity of the transverse tie rod, a first threaded block is symmetrically fixedly installed in the inner cavity of the transverse tie rod, the bidirectional screw is threadedly connected to the first threaded block, and a first adjusting bolt is fixedly installed on the surface of the bidirectional screw for driving the bidirectional screw to rotate.

[0012] By setting up a transverse pulling mechanism and driving the bidirectional screw rod to rotate through the first adjusting bolt, the length of the transverse tie rod can be adjusted to ensure the tight connection of adjacent fourth connecting plates. The adjacent fourth connecting plates are connected by the transverse tie rod, and a rigid triangular connection is constructed between adjacent support columns. The independent support columns are connected in series to form a spatial truss system. The axial tensile and compressive stresses are transmitted to adjacent support points through the transverse tie rod, thereby avoiding the local bending moment accumulation caused by traditional shear force transmission and significantly improving the lateral support performance.

[0013] In a preferred embodiment, a connecting mechanism is installed on the surface of the long support column for controlling the connection between the second connecting ear and the second connecting block. The connecting mechanism includes a driving block, a mounting block and a limiting rod. The driving block is symmetrically slidably installed in the inner cavity of the connecting seat. The bottom of the driving block is wedge-shaped. A mounting block is fixedly installed on the surface of the driving block. A limiting rod is fixedly installed on the side wall of the mounting block. One end of the limiting rod is inserted into the second connecting block for hingedly connecting the second connecting ear and the second connecting block.

[0014] In a preferred solution, a slider is symmetrically fixedly installed on the side wall of the driving block, a sliding groove is symmetrically opened in the inner cavity of the connecting seat, the slider is slidably installed in the inner cavity of the sliding groove, a spring is fixedly installed on the side wall of the driving block, and the other end of the spring is fixedly connected to the connecting seat for driving the limit rod to move toward the direction of the second connecting ear.

[0015] In a preferred solution, an adjusting screw is installed in the inner cavity of the mounting block, a second threaded block is fixedly installed in the inner cavity of the mounting block, the adjusting screw is threadedly connected to the second threaded block and is used to drive the driving block to move, and a second adjusting bolt is fixedly installed at one end of the adjusting screw and is used to drive the adjusting screw to rotate.

[0016] In a preferred solution, a driving ring is slidably sleeved on the surface of the long support column, and the surface of the driving ring is wedge-shaped. The wedge surface of the driving ring is matched with the wedge surface of the driving block, and is used to drive the driving block to move. A lifting block is also sleeved on the surface of the long support column, and a connecting rod is connected between the lifting block and the driving ring. A jack is symmetrically installed on the surface of one of the temporary support bases, and the telescopic end of the jack is in contact with the bottom of the lifting block, and is used to drive the lifting block to lift and lower.

[0017] By setting up a connecting mechanism, when the construction is completed and the supporting device needs to be removed, the two short supporting columns are first removed using the lifting equipment, and then the lifting block is driven up by the jack, which drives the driving ring to rise synchronously, and squeezes the driving block, thereby driving the limit rod to disengage from the second connecting block. The connection between the long supporting column and the double X-column can be released without manual climbing operation, which facilitates construction.

[0018] The present invention provides a temporary support device for double X-column installation, which has the following beneficial effects: By setting up a support mechanism, two groups of supports are adopted, a long support column plus a group of short support columns, which is relatively safe and simple. The long support column serves as the main load-bearing structure and bears more than 70% of the vertical load; the double-support short support column shares the remaining vertical load through the first intersection and absorbs horizontal forces such as wind load and lifting swing force, forming a "main-auxiliary coordinated" force mechanism to avoid the risk of overloading of a single support, and the two fulcrums of the short support column diffuse the local stress to the adjacent pipe sections, reducing the stress concentration factor and increasing the stability of the device.

[0019] 2. By setting up a transverse pulling mechanism, the bidirectional screw is driven to rotate by the first adjusting bolt, so as to adjust the length of the transverse tie rod, ensure the close connection of adjacent fourth connecting plates, connect the adjacent fourth connecting plates by the transverse tie rod, construct a rigid triangular connection between adjacent support columns, connect the independent support columns in series into a spatial truss system, and transmit the axial tensile and compressive stress to the adjacent support points by the transverse tie rod, so as to avoid the local bending moment accumulation caused by traditional shear force transmission and significantly improve the lateral support performance.

[0020] 3. By setting up the connection mechanism, when the construction is completed and the supporting device needs to be removed, first use the lifting equipment to remove the two short supporting columns, and then use the jack to drive the lifting block to rise, drive the driving ring to rise synchronously, squeeze the driving block, and drive the limit rod to disengage from the second connecting block, so as to release the connection between the long supporting column and the double X column, without manual climbing operation, which is convenient for construction.
