Description

Technical Field

[0001] The utility model relates to the technical field of concrete cast-in-place construction, in particular to a building template top supporting device. Background Art

[0002] Building formwork is a temporary supporting and protective structure that needs to be manufactured according to construction requirements and installed in the specified position using concrete structure. During the construction process, the building formwork needs to bear its own weight and the external loads acting on it. Using building formwork during the construction process can ensure the quality and construction safety of the concrete project and speed up the construction progress.

[0003] Chinese patent publication number CN220167599U proposes "a top supporting device for building formwork in construction projects". This technical solution addresses the problem that "existing devices generally support the bottom of the building formwork through a support frame to improve the supporting performance of the building formwork. However, when the existing devices support the building formwork, when facing building formworks of different specifications and shapes, the support contact area is not comprehensive enough, thereby reducing the support stability". The utility model provides the following technical solution: "By rotating and unfolding the support frame, the contact area between the top plate and the building formwork is increased, thereby improving the support stability of the building formwork. At the same time, by unfolding the support frame, it can adapt to building formworks of different shapes and specifications, thereby enhancing the support adaptability."

[0004] The above solution has the following defects: after the multiple support frames are unfolded, the multiple rotating frames need to be adjusted in sequence so that the multiple limit plates are located under the multiple support frames before the multiple support frames can be limited. Therefore, the above process is too cumbersome and time-consuming, so a building formwork top support device is proposed to solve the above problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a building formwork roof supporting device, which has the advantages of being simple and quick to operate.

[0006] In summary, the present invention provides the following technical solutions: a building template top supporting device, comprising an outer tube, an expansion support mechanism arranged at the top of the outer tube, and a lower end stabilizing mechanism arranged at the bottom of the outer tube.

[0007] The expansion support mechanism includes an externally threaded inner rod movably installed inside the outer cylinder, limit blocks fixedly installed on both sides of the externally threaded inner rod, a hollow slot plate fixedly installed on the top of the externally threaded inner rod, an upper top plate fixedly installed on the top of the hollow slot plate, two expansion plates slidably installed inside the upper top plate, a lower pull rod rotatably installed on the bottom of the two expansion plates and passing through the interior of the hollow slot plate, a moving block rotatably installed on the bottom of the two lower pull rods, a rubber pad fixedly installed on the top of the two expansion plates, and a rotation adjustment mechanism located inside the hollow slot plate.

[0008] The rotation adjustment mechanism includes a bidirectional screw rotatably installed inside the slotted plate and a knob fixedly installed on the right side of the bidirectional screw.

[0009] Furthermore, the lower end stabilizing mechanism includes a telescopic rod fixedly installed on the bottom of the outer tube, a first lower base plate fixedly installed on the bottom of the telescopic rod, three side support rods rotatably installed on the outside of the outer tube, and a second lower base plate rotatably installed on the bottom of the three side support rods.

[0010] The beneficial effect of adopting the above further solution is that the bottom of the building formwork top supporting device is supported by the provided lower end stabilizing mechanism.

[0011] Furthermore, an internal threaded sleeve is rotatably mounted on the top of the outer cylinder and is sleeved on the outside of the external threaded inner rod. The internal threaded sleeve is threadedly connected to the external threaded inner rod, and a rotating disk is fixedly mounted on the outside of the internal threaded sleeve.

[0012] The beneficial effect of adopting the above further solution is that by holding the rotating disk and controlling the forward and reverse rotation of the internal thread sleeve, the external thread inner rod can be raised and lowered inside the outer cylinder.

[0013] Furthermore, the two limit blocks both penetrate into the interior of the outer cylinder, and the externally threaded inner rod and the two limit blocks both slide up and down inside the outer cylinder.

[0014] The beneficial effect of adopting the above further solution is that the externally threaded inner rod is restricted to rise and fall inside the outer cylinder by the two limiting blocks.

[0015] Furthermore, the length of the hollow plate is the same as that of the upper plate, the outer portion of the upper plate is a "T"-shaped structure, and the two expansion plates both penetrate to the outer side of the upper plate.

[0016] The beneficial effect of adopting the above further solution is that the bottom of the building template is supported by the installed upper top plate, and the area of the upper top plate can be increased by installing two expansion plates, thereby making the bottom support of the building template more stable.

[0017] Furthermore, the two lower pull rods are movably connected to the upper top plate, the two movable blocks slide left and right inside the empty slot plate, the two rubber pads are located on the top of the upper top plate, and the inner sides of the two rubber pads are chamfered.

[0018] The beneficial effect of adopting the above-mentioned further scheme is that the bottoms of the two expansion plates are supported respectively by two lower pull rods, and when the two expansion plates move outward, the two rubber pads can be driven to move at the same time. When the two rubber pads move to the outside of the upper top plate, the gap between the expansion plates and the upper top plate can be filled. When the two expansion plates are retracted into the inside of the upper top plate, the chamfers on the inner sides of the rubber pads contact and squeeze the side edges of the upper top plate, allowing the rubber pads to slide to the top of the upper top plate.

[0019] Furthermore, the bidirectional screw penetrates to the right side of the empty slot plate, the bidirectional screw thread is installed inside the two moving blocks, and the bidirectional screw is located on the right side of the empty slot plate.

[0020] The beneficial effect of adopting the above-mentioned further scheme is that by holding the knob and controlling the forward and reverse rotation of the bidirectional screw, the two moving blocks can be forced to move closer to and away from each other. When the two moving blocks move away from each other, the two expansion plates can be pushed outward through the two lower pull rods. When the two moving blocks move closer to each other, the two lower pull rods can pull the two into the interior of the upper top plate.

[0021] Furthermore, the expanded end of the telescopic rod faces downward, and the exterior of the first lower base plate is a rectangular structure.

[0022] The beneficial effect of adopting the above further solution is that the bottom of the outer cylinder can be supported by pulling the telescopic rod downward so that the first lower base plate contacts the ground.

[0023] Furthermore, the three side support rods are all located on the outside of the first lower base plate, and the bottoms of the three second lower base plates are all fixedly mounted with anti-slip teeth.

[0024] The beneficial effect of adopting the above further solution is that the three side support rods and the second lower base plate are extended outward to support the outer side of the outer tube, thereby preventing the outer tube from tipping over laterally, and the installed anti-slip teeth contact the ground to play an anti-slip role.

[0025] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0026] The building formwork top supporting device controls the forward rotation of the bidirectional screw to force the two moving blocks to move away from each other. The two moving blocks move away from each other and push the two expansion plates and rubber pads to expand outward through the two lower pull rods, thereby increasing the top area of the upper top plate. Subsequently, the externally threaded inner rod is controlled to rise so that the upper top plate and the two rubber pads come into contact with the building formwork, thereby supporting its bottom, thereby achieving the effect of simple and quick operation.
