Description

[Technical Field]

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a device for adjusting the height difference of composite floor slabs. [Background Technology]

[0002] In current building construction, composite slabs are widely used in structural floors. These slabs are typically 60mm thick and weigh approximately 150kg / m². During installation and hoisting, the non-prestressed weight of the composite slabs generates bending moments, causing warping and unevenness at the bottom. Simultaneously, the support frame also exhibits flatness deviations. All of these factors directly affect the installation quality. After installation, the flatness deviation of the bottom surface exceeds the ±5mm specification requirement. Due to the slabs' heavy weight, manual adjustment is laborious and time-consuming, and may even damage the edges, affecting structural quality, leading to defects, and causing homeowner dissatisfaction and complaints.

[0037] Composite floor slabs are installed on support frames. During installation and hoisting, the composite slabs experience bending moments due to their non-prestressed self-weight, and the slabs themselves may warp, resulting in unevenness at the bottom. Simultaneously, the support frame erection may also have flatness deviations. All of these factors directly affect the installation quality of the composite slabs. If the flatness deviation of the bottom surface elevation of the composite slab exceeds the ±5mm specification requirement after installation, adjustments are necessary.

[0038] To improve the construction methods of composite slabs in existing technologies and enhance project quality, this embodiment provides a height adjustment device for composite floor slabs using an electro-hydraulic system, such as... Figures 1 to 5As shown, the composite floor slab height-lowering electro-hydraulic adjustment device is located at the position where the flatness deviation of the bottom surface of the composite floor slab exceeds the limit, and includes:

[0039] The movable base 1 includes a rectangular base plate 11 and casters 12 with brake devices 13 installed at the four corners of the base plate.

[0040] An electric hydraulic press 2 is mounted on the base plate of a movable base and is used to drive the lifting rod 4 to rise and fall.

[0041] The lifting rod 4 is connected at its bottom to the electric hydraulic press 2, and the top of the lifting rod is provided with a top support structure that supports the position where the flatness deviation of the bottom surface of the composite floor slab 5 exceeds the limit.

[0042] A stabilizing tripod 3 is provided, the apex of which is connected to a lifting rod. The stabilizing tripod is provided with a diagonal brace 31, the bottom of which is supported on the base plate of the movable base.

[0043] This utility model discloses an electro-hydraulic height adjustment device for composite floor slabs. This device is installed at locations where the flatness deviation of the bottom surface of the composite floor slab exceeds the limit, commonly due to downward warping, requiring jacking and correction. Utilizing the principle of hydraulic lifting, an electro-hydraulic press drives a lifting rod to rise and fall. During the ascent, the lifting rod, through a top support structure, lifts the composite floor slab, eliminating the flatness deviation of the bottom surface. Practical operation has shown that this device can save significant labor, further control quality standards, improve construction efficiency, and enhance the overall project quality.

[0044] Because the mobile base is equipped with casters with brakes at the four corners of the base plate, it is easy to move on the floor. After moving to the set position, the brakes lock the casters to prevent the mobile base from moving during the operation of the electric hydraulic height adjustment device for the composite floor slab.

[0045] The apex of the stabilizing tripod is connected to the lifting rod, and the bottom of its diagonal brace is supported on the base plate of the movable base to ensure the stability of the lifting rod during the lifting process.

[0046] Furthermore, the upper center of the base plate is provided with a positioning post 14 for mounting the electric hydraulic press, and the bottom of the electric hydraulic press is provided with a positioning hole that mates with the positioning post. This facilitates the installation of the electric hydraulic press.

[0047] Specifically, the base plate 11 is a rectangular steel plate, and the caster wheel 12 with a brake device is bolted to the base plate. The rectangular steel plate is made of 300mm × 300mm × 50mm thick steel plate, with the center welded. A 100mm long round steel bar is used as a positioning post.

[0048] Referring to existing electric hydraulic presses, the electric hydraulic press 2 includes a hydraulic cylinder 21, a hydraulic pump 22 for driving the hydraulic cylinder, an electric motor 23, a battery pack 25 for powering the electric motor 23, and an oil tank 26 for supplying fluid to the hydraulic pump. The battery pack can be a 36V storage battery, and the electric motor 23 is connected to a directional valve 24.

[0049] Furthermore, the stabilizing tripod 3 also includes upper and lower support plates 32. The upper support plate is movably fitted with the lifting rod 4, and the lower support plate is movably fitted with the electric hydraulic press 2. The upper support plate is connected to the top of the diagonal brace, and a horizontal support rod 34 connects the lower support plate to the diagonal brace. The upper support plate stabilizes the lifting rod, whose bottom is inserted into the hydraulic rod. The lower support plate stabilizes the electric hydraulic press. Additionally, because the bottom of the electric hydraulic press has positioning holes that mate with positioning columns, combined with the stabilizing effect of the lower support plate, fasteners can be omitted from fixing the electric hydraulic press. This facilitates the combined use of the electric hydraulic press with the movable base and the lifting rod, making installation and disassembly convenient.

[0050] For easy assembly and disassembly, the support plate has a notch. The notch of the upper support plate fits into the lifting rod, and the upper support plate is bolted to a locking plate that closes the notch. The notch of the lower support plate fits into the electric hydraulic press, and the lower support plate is connected to a locking hook 33. The locking hook is connected to one of the diagonal braces, and the corresponding diagonal brace may not be connected to the horizontal brace.

[0051] Specifically, the stable tripod 3 is provided with four diagonal braces 31. The diagonal braces 31 and the horizontal braces 34 are both made of round steel. The support plate 32 is made of steel plate. The top of the diagonal braces is welded and fixed to the upper support plate. The horizontal braces are welded and fixed to the lower support rod and the diagonal braces.

[0052] Specifically, the lifting rod 4 includes at least two rod sections 41, and adjacent rod sections are connected by a fixing sleeve 42. For example, the first rod section is a 1.5m long DN48 galvanized pipe, the fixing sleeve is a 300m long DN50 galvanized sleeve, and the second rod section is a DN48 galvanized pipe customized according to the building's floor height and inserted into the fixing sleeve.

[0053] In some embodiments, the top support structure includes a support base 43 and a rubber gasket 44 fixed to the support base 43. Specifically, the support base is a channel steel, and its bottom surface 431 is welded to the upper end of the second rod section. The rubber gasket is bonded and fixed inside the channel steel using AB glue 432.

[0054] This implementation method utilizes the principle of hydraulic lifting and employs an electric hydraulic adjustment device for the height of composite floor slabs. Actual operation has shown that it can save significant amounts of labor, further control quality standards, improve construction efficiency, and enhance the overall project quality.

[0055] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the utility model will be included within the scope of the claims.
