[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0035] An embodiment of the present application provides a height adjustment device for steel beam assembly, which can solve the problem in the related art that the method of using several steel plates of different thicknesses for padding to change the top elevation of a temporary support device on the top surface of a steel beam assembly bracket is cumbersome to operate, has high construction costs and is not very accurate.

[0036] See also Figures 1 to 4 As shown, the embodiment of the present application provides a height adjustment device for assembling steel beams, comprising:

[0037] Base 1;

[0038] The support base 2 comprises a slider 21 vertically slidably connected to the base 1, and one end of the slider 21 away from the base 1 is rotatably connected to a top plate 22;

[0039] There are multiple lifting members 3 circumferentially arranged between the base 1 and the top plate 22 . The multiple lifting members 3 drive the top plate 22 to move vertically to change the height and pitch angle of the top plate 22 .

[0040] The support base 2 of the elevation adjustment device for assembling steel beams of the embodiment of the present application includes a slider 21 vertically slidably connected to the base 1, and the end of the slider 21 away from the base 1 is rotatably connected to the top plate 22. A plurality of jacking members 3 are circumferentially arranged between the base 1 and the top plate 22. The plurality of jacking members 3 drive the top plate 22 to move vertically to change the height and pitch angle of the top plate 22.

[0041] During specific implementation, the base 1 is placed on the top surface of the steel beam assembly bracket. By controlling multiple jacking members 3 to push the top plate 22 upward and ensuring that the heights of the multiple jacking members 3 pushing the top plates 22 are the same, the height of the top plate 22 can be adjusted. The top plate 22 is used to support the steel beam and can be accurately adjusted according to the elevation adjustment requirements. It is easy to operate. At the same time, since the top plate 22 is rotatably connected to the slider 21, if the pushing heights of the top plate 22 by each jacking member 3 are different, the top plate 22 can be made to pitch and rotate around the slider 21, thereby realizing the switching of the top plate 22 between horizontal and inclined to meet different temporary support requirements, optimize the elevation adjustment process, and improve the construction efficiency and accuracy of the elevation adjustment of the steel beam assembly construction.

[0042] It should be noted that multiple lifting members 3 can independently push the top plate 22 upward, and the bottom surface of the top plate 22 is abutted against the lifting member 3 by its own weight. Since the slider 21 connected to the top plate 22 is limited by the base 1, when the top plate 22 moves upward, it drives the slider 21 to slide up along the base 1, and the slider 21 can prevent the top plate 22 from sliding off the lifting member 3.

[0043] In some alternative embodiments: See Figures 1 to 4 As shown, an embodiment of the present application provides a height adjustment device for assembling steel beams, wherein a first hinge seat 4 is fixed to the end of a slider 21 of the height adjustment device away from a base 1, and a second hinge seat 5 is fixed to the side of a top plate 22 close to the slider 21, and the first hinge seat 4 and the second hinge seat 5 are hingedly connected by a pin shaft.

[0044] In the embodiment of the present application, the top plate 22 and the slider 21 are rotatably connected by means of a pin hinge connection through the first hinge seat 4 and the second hinge seat 5 .

[0045] Exemplarily, the number of jacking members 3 is four and they are distributed at equal intervals in the circumferential direction, wherein two jacking members 3 are located in the rotation direction of the top plate 22. When the supporting heights of the two jacking members 3 are different, the top plate 22 will rotate accordingly to maintain contact with the two jacking members 3. Then, the inclination angle of the top plate 22 can be adjusted by controlling the jacking members 3 to meet the demand for supporting the inclined surface during the steel beam assembly construction.

[0046] In some alternative embodiments: See Figures 1 to 4 As shown, an embodiment of the present application provides a height adjustment device for assembling steel beams, wherein the outer peripheral surface of a slider 21 of the height adjustment device for assembling steel beams is a cylindrical surface, and a circular hole is provided on the base 1 for the slider 21 to be vertically inserted and adapted to the cylindrical surface.

[0047] The slider 21 of the embodiment of the present application is vertically slidably connected in the circular hole on the base 1. Since the outer peripheral surface of the slider 21 is a cylindrical surface, the slider 21 can also rotate radially relative to the base 1, so that the top plate 22 connected with the slider 21 in a spacing relationship can rotate horizontally, and the first hinge seat 4 and the second hinge seat 5 are cooperated to realize the structure of the rotational connection between the top plate 22 and the slider 21 in a pin-hinged manner, so that when the base 1 is fixed, by changing the pushing height of the top plate 22 by each lifting member 3, the top plate 22 can be pitched at any height or horizontal direction in the adjustment stroke.

[0048] It should be noted that, illustratively, the slider 21 can be made of a cylinder or a round tube, and can be hollowed out to reduce weight while ensuring strength.

[0050] The second hinge seat 5 of the embodiment of the present application includes a connecting section 51 and a fixed section 52, which are rotatably connected to allow the top plate 22 to have horizontal rotation freedom, and then cooperate with the first hinge seat 4 and the connecting section 51 to realize the pitch structure of the top plate 22 through hinge connection, so that when the base 1 is fixed, by changing the pushing height of the top plate 22 by each lifting member 3, the top plate 22 can be pitched at any height or horizontal direction in the adjustment stroke.

[0051] In some alternative embodiments: See Figures 1 to 4 As shown, an embodiment of the present application provides a height-adjusting device for assembling steel beams, wherein the connecting section 51 of the height-adjusting device for assembling steel beams has one end away from the pin shaft protruding outwardly to form an annular flange 511, and the fixed section 52 is provided with a groove 521 for accommodating the annular flange 511, and the fixed section 52 has one end away from the top plate 22 protruding inwardly to form a limiting flange 522 for limiting the annular flange 511 from escaping from the groove 521.

[0052] The annular flange 511 on the connecting section 51 of the embodiment of the present application can rotate in the groove 521 on the fixing section 52 . The inner walls of the annular flange 511 and the groove 521 are both smooth surfaces. The limiting flange 522 prevents the annular flange 511 from being separated from the groove 521 .

[0053] In some alternative embodiments: See Figures 1 to 4 As shown, an embodiment of the present application provides a height-adjusting device for assembling steel beams, wherein a base 1 of the height-adjusting device for assembling steel beams comprises an outer tube 11 and a ring plate 12 fixed on the outer tube 11, a reinforcing plate 13 is fixed between the ring plate 12 and the outer plate, a slider 21 is vertically slidably connected to the outer tube 11, and a lifting member 3 is arranged between the ring plate 12 and the top plate 22.

[0054] The ring plate 12 of the embodiment of the present application is used to install and arrange the lifting member 3, and the reinforcing plate 13 is used to improve the connection strength between the ring plate 12 and the outer plate;

[0055] Exemplarily, the number of reinforcing plates 13 and the number of lifting members 3 are the same and the reinforcing plates 13 and the lifting members 3 are alternately distributed in the circumferential direction to ensure that the connection between the annular plate 12 and the lifting members 3 can withstand a relatively large pressure.

[0057] The thread inclination angle of the lifting screw 31 of the embodiment of the present application meets the self-locking condition. When the lifting screw 31 is rotated, the top end of the lifting screw 31 pushes the top plate 22. When the lifting screw 31 is pressed, the height can be guaranteed to remain unchanged.

[0058] In some alternative embodiments: See Figures 1 to 4 As shown, an embodiment of the present application provides a height adjustment device for assembling steel beams, wherein a mounting hole 121 for a lifting screw 31 to pass through is provided on a ring plate 12, and a screw sleeve 32 connected to the mounting hole 121 and threadedly connected to the lifting screw 31 is fixed on the ring plate 12.

[0059] The lifting screw 31 of the embodiment of the present application passes through the mounting hole 121 on the ring plate 12 and is threadedly connected to the screw sleeve 32. When the thread on the screw sleeve 32 is worn, the screw sleeve 32 can be replaced.

[0060] For example, the screw sleeve 32 can be welded to the ring plate 12 , and when replacement is needed, a new screw sleeve 32 can be directly cut and welded; or a slot can be opened on the top of the ring plate 12 and the screw sleeve 32 can be fixed in the slot.

[0062] The ball head end of the ball head rod 6 of the embodiment of the present application can slide in the ball socket of the universal joint seat 7, so that the top block 34 can tilt with the top plate 22. At the same time, the top block 34 can prevent the end of the lifting screw 31 from directly contacting the top plate 22 and causing the force point to be too small.
