Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a temporary auxiliary supporting device for a cantilever beam. Background Art

[0002] In contemporary architecture, cantilever scales are getting larger and larger, and there are more and more ways to apply them. Among them, the cantilever beam is the most common cantilever structure. A cantilever beam is a beam with one end buried or cast on a support and the other end extending out of the support. Most of them are made of reinforced concrete, and their cross-sectional height is generally 1 / 6 to 1 / 8 of the span. During the casting process, cantilever beams are mostly supported to ensure that they meet the requirements after casting.

[0003] A Chinese utility model patent with the announcement number CN218346953U discloses a temporary support structure for a cantilever beam, which includes a support body and a support top plate arranged between the support body and the cantilever beam for supporting the cantilever beam, the support body includes a plurality of support segments arranged in sequence along the height direction, a first sleeve and a second sleeve are fixedly arranged on the side wall of the support segment along the height direction, a connecting assembly for detachably connecting the second sleeve of the support segment and the first sleeve of the adjacent support segment is provided between the second sleeve of the support segment and the first sleeve of the adjacent support segment, and the support top plate is connected to the adjacent support segment. The disclosed support structure has the effect of being repeatedly used for temporary support of the cantilever beam.

[0004] However, in the above-mentioned patent, the cantilever beam is supported by splicing multiple support segments.

[0037] like Figures 1 to 4 As shown, a temporary auxiliary support device for a cantilever beam includes a support base plate 1, an adjustment base 2, a support pipe splicing unit 3 and a top support seat 4.

[0038] Adjusting screws 11 are movably mounted on the left and right ends of the upper surface of the supporting base plate 1 . An internally threaded adjusting cylinder 12 is threadedly sleeved on the adjusting screw 11 . An adjusting handle 13 is arranged on the top of the adjusting screw 11 .

[0039] The adjusting base 2 is located above the supporting base plate 1. The length of the adjusting base 2 is smaller than the length of the supporting base plate 1, and the width of the adjusting base 2 is larger than the width of the supporting base plate 1. Wheels 21 are installed on the left and right sides of the front and the left and right sides of the back of the adjusting base 2. Connecting components are provided in the middle position of the left side and the middle position of the right side of the adjusting base 2. The connecting components are hinged on the outer wall of the corresponding internally threaded adjusting cylinder 12. Fixed bottom tubes 24 are provided at the four corners of the upper surface of the adjusting base 2, and a first externally threaded section 25 is provided on the outer wall of the fixed bottom tube 24.

[0040] The connecting assembly includes two front and rear height adjustment bearings 22 installed at the center positions of the left and right sides of the adjustment base 2. The internal thread adjustment cylinder 12 is arranged between the front and rear height adjustment bearings 22 on each side. The outer wall of the internal thread adjustment cylinder 12 and the front and rear height adjustment bearings 22 are hingedly connected through a pin shaft 23.

[0041] The support tube splicing unit 3 is connected to the fixed bottom tube 24, and the support tube splicing unit 3 includes a plurality of support long tubes 31. A bent short tube 32 is provided between each adjacent support long tube 31. The adjacent support long tubes 31 are hinged to the bent short tubes 32. A second external thread section 35 is provided on the upper end of the outer surface of the support long tube 31, and a support sleeve 36 is slidably sleeved on the lower end of the outer surface. A second internal thread section 37 is provided on the lower end of the support sleeve 36.

[0042] The two ends of the supporting long tube 31 and the bending short tube 32 are sealed, and the two ends of the supporting long tube 31 are provided with a first hinge seat 33, and the two ends of the bending short tube 32 are provided with a second hinge seat 34.

[0047] In the embodiment of the utility model, by arranging the supporting long tube 31 and the bent short tube 32 at intervals, and then utilizing the movable hinge of the first hinge seat 33 and the second hinge seat 34, the supporting assembly composed of the supporting long tube 31 and the bent short tube 32 can be folded and unfolded. The unfolding thereof can support the cantilever beam, and the folding thereof can facilitate the transportation and storage of the device.

[0048] In the embodiment of the utility model, the support sleeve 36 is arranged so as to be sleeved between the two support long tubes 31 and wrap the bent short tube 32. At the same time, the first hinge seat 33 and the second hinge seat 34 are both located in the support sleeve 36. The two adjacent support long tubes 31 can pass through the limit of the support sleeve 36 and are fastened by the second external thread section 35 and the second internal thread section 37 to be assembled into a long tube. The assembly method is simple, fast and convenient, and the splicing efficiency can be improved.

[0049] In the embodiment of the utility model, a movable hinge is adopted between the first hinge seat 33 and the second hinge seat 34, so that the long support tube 31 and the short bending tube 32 can be rotated to facilitate their folding and unfolding. At the same time, the hinge mode can be set to be detachable, so that construction personnel can choose the appropriate number of long support tubes 31 and short bending tubes 32 according to the height of the cantilever beam, so that the device can meet the support of cantilever beams of different heights and improve the scope of use.

[0050] In the embodiment of the utility model, the fixed bottom tube 24 and the fixed top tube 41 can be connected to the support tube splicing unit 3, so that the device can be arranged as an integral whole, which is convenient for handling and transportation of the device on the one hand, and can reduce the space occupied by the device on the other hand, making it convenient for storage.

[0051] In the utility model, a first external thread section 25 is provided on the outer surface of the fixed bottom tube 24, and the first external thread section 25 is connected to the second internal thread section 37 on the lowest supporting long tube 31. A third hinge seat 26 is provided on the upper end of the fixed bottom tube 24, and the third hinge seat 26 is movably hinged to the first hinge seat 33 on the lowest supporting long tube 31; the fixed bottom tube 24 and the supporting long tube 31 can be folded and spliced ​​by using the supporting sleeve 36, and at the same time, the contact between the supporting sleeve 36 and the lower base 2 is utilized to ensure the stability of the fixation of the supporting long tube 31 after splicing.

[0052] In the utility model, the fourth hinge seat 42 at the lower end of the fixed top pipe 41 is movably hinged with the first hinge seat 33 on the uppermost supporting long tube 31, and a top fixing sleeve 43 is slidably sleeved on the fixed top pipe 41. The first internal thread section 44 of the top fixing sleeve 43 is threadedly connected with the second external thread section 35 of the uppermost supporting long tube 31; this can ensure that the fixed top pipe 41 can be quickly folded and spliced ​​with the supporting long tube 31, and the top fixing sleeve 43 is used to ensure the firmness after splicing.

[0053] When the utility model is used specifically, the device is moved to the supporting location, and then the adjusting handle 13 is rotated to drive the adjusting screw 11 to rotate, thereby adjusting the height of the supporting base plate 1, so that it gradually descends to contact the ground, and the wheels 21 are separated from the ground. Then, according to the height of the cantilever beam, the staff disassembles the connection between the first hinge seat 33 and the second hinge seat 34, and then uses the corresponding number of supporting long tubes 31 and bent short tubes 32 to form the supporting tube splicing unit 3;

[0054] Then the staff lifts the top support seat 4 so that the two uppermost support long tubes 31 begin to unfold. At the same time, the support sleeve 36 slides downward with the unfolding of the support long tube 31 and wraps the first hinge seat 33 and the second hinge seat 34. Then the staff rotates the support sleeve 36 to connect the second internal thread section 37 with the second external thread section 35, and then fixes the two support long tubes 31 with the support sleeve 36. Then the fixed support long tube 31 is lifted to unfold the subsequent two support long tubes 31 and fix them in the same way until the top support seat 4 moves to the bottom of the cantilever beam.

[0055] In this process, the connection between the fixed top pipe 41 and the uppermost supporting long pipe 31 is also adopted in the above manner, and the connection between the fixed bottom pipe 24 and the lowermost supporting long pipe 31 is also adopted in the above manner, so that the top support seat 4 is supported by the four groups of expanded support pipe splicing units 3;

[0056] At this time, the staff adjusts the height and angle of the adjustment base 2 by turning the adjustment handle 13 and using the adjustment screw 11 to drive the internal thread adjustment cylinder 12 to rotate, so that the top support seat 4 is in full contact with the lower surface of the cantilever beam, and the cantilever beam is supported.

[0057] All parts of the device can be made of aluminum alloy to reduce the weight of the device, thereby making it easier for workers to operate during the propping process of the top support seat 4.

[0058] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
