Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a hydraulic unloading support. Background Technology

[0002] For example, Chinese utility model patent publication number CN 207862778 U discloses a wedge-shaped unloading steel support suitable for unloading various types of supports. This device includes two sets of symmetrical wedge-shaped blocks, one above the other and one to the left and right, anchored in the middle by tie rods. Two stiffening ribs are welded to the middle of the wedge-shaped blocks to prevent localized deformation. However, it is not convenient for flexibly controlling the movement of the left and right wedge-shaped blocks. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a hydraulically dismountable support, which can flexibly adjust the movement of the left and right supports through a hydraulic jack, and control the lower support to be grounded or retracted.

[0004] To solve the above problems, a hydraulically dismounted support is adopted, which includes:

[0005] The substrate is mounted on the bottom surface of the steel frame support.

[0006] The upper support is installed under the base plate;

[0007] The lower support is spaced below the upper support.

[0008] T-slots are formed on the wedge-shaped surfaces of the upper and lower supports;

[0009] The left and right supports are slidably assembled between the upper and lower supports and slidably mounted on the left and right wedge-shaped surfaces of the upper and lower supports.

[0010] The T-shaped slider is fixed to the bottom surfaces of the left and right supports and is slidably adapted to the T-shaped groove.

[0011] The reaction frames are installed in pairs on the bottom surface of the steel frame foundation, and are spaced apart from the left and right supports respectively.

[0012] Hydraulic jacks are installed in pairs on the reaction frame, with the opposite piston ends facing the left and right supports respectively;

[0013] The jacking block is installed on the piston end of the hydraulic jack;

[0014] The universal ball is installed on the front and back of the push block, and the universal ball installed on the front of the push block abuts against the left support and the right support.

[0015] The concave slide rail is installed on the back of the left and right supports and is inserted by the push block. The universal ball installed on the back of the push block abuts against the concave slide rail.

[0016] With this structure, the left and right supports can be moved along the wedge-shaped surfaces of the upper and lower supports by the telescopic movement of the hydraulic jacks, thereby lifting or removing the lower support so that it can move away from and contact the ground; together with the steel frame foundation, the central load of the steel frame foundation is transferred to the ground, and at the same time, it bears the role of resisting the central bending moment of the steel frame foundation.

[0017] As a further improvement of this utility model, a pad is installed on the bottom surface of the lower support.

[0018] With this structure, the pad helps to increase the area of ​​the ground that bears the force.

[0019] As a further improvement of this utility model, the concave slide rails are arranged side by side at intervals, and the piston end of the hydraulic jack extends into the space between the two concave slide rails. The push block extends into the space between the concave slide rail and the left support, and between the concave slide rail and the right support.

[0020] With this structure, the hydraulic jack can stably move the left and right supports;

[0021] As a further improvement of this utility model, a transverse J-shaped fixing bracket is installed on the back of the concave slide rail. One end of the J-shaped fixing bracket is fixed to the back of the left and right supports, and the other end is fixed to the back of the concave slide rail.

[0022] This structure strengthens the concave slide rail and prevents it from bending.

[0023] As a further improvement of this utility model, a tripod is fixed at the corner of the J-shaped fixing bracket.

[0024] With this structure, the tripod helps to stabilize the corner parts.

[0025] As a further improvement of this utility model, the push block is a stepped frustum shape.

[0026] With this structure, the stepped frustum shape facilitates the installation of both front and back universal joints, providing sufficient installation space for both sides.

[0027] This utility model is beneficial to the stable erection of the steel frame foundation. The four corners of the steel frame foundation are moved to designated positions by drive wheels, then positioned by a worm gear lift, and finally grounded by hydraulic unloading supports. This is to resist the bending moment in the middle of the steel frame foundation and transfer the load to the ground when the formwork is erected and concrete is poured on the truss platform supported above the steel frame foundation.

[0042] The reaction frame 9 is installed in pairs on the bottom surface of the steel frame support 2, and is spaced apart from the left support 6 and the right support 7 respectively;

[0043] Hydraulic jacks 10 are installed in pairs on the reaction frame 9, with their opposite piston ends facing the left support 6 and the right support 7 respectively.

[0044] The jacking block 11 is installed on the piston end of the hydraulic jack 10;

[0045] The universal ball 12 is installed on the front and back of the push block 11. The universal ball 12 installed on the front of the push block 11 abuts against the left support 6 and the right support 7.

[0046] The concave slide rail 13 is installed on the back of the left support 6 and the right support 7 and is extended into by the push block 11. The universal ball 12 installed on the back of the push block 11 abuts against the concave slide rail 13.

[0047] With this structure, the extension and retraction of the hydraulic jack 10 can drive the left support 6 and the right support 7 to move along the wedge-shaped surfaces of the upper support 3 and the lower support 4, thereby lifting or removing the lower support 4 so that the lower support 4 can move away from and contact the ground; in conjunction with the steel frame pier 2, the central load of the steel frame pier 2 is transferred to the ground, and at the same time, it bears the role of resisting the central bending moment of the steel frame pier 2.

[0048] In this embodiment, a pad 14 is installed on the bottom surface of the lower support 4.

[0049] With this structure, the pad 14 is beneficial to increasing the stress-bearing area of ​​the rigid ground.

[0050] In this embodiment, the concave slide rails 13 are arranged side by side at intervals, and the piston end of the hydraulic jack 10 extends into the space between the two concave slide rails 13. The push block 11 extends into the space between the concave slide rail 13 and the left support 6, and between the concave slide rail 13 and the right support 7.
