Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a top-return supporting device for a basement. Background Art

[0002] The basement roof is often used as a material transportation channel and temporary storage yard during the construction phase. However, the reinforced basement roof often cannot meet the required bearing capacity requirements, which may lead to structural safety problems and affect construction efficiency. In order to ensure that the basement roof can safely and effectively bear the tasks of material transportation and storage yard, it is necessary to reinforce it. By reinforcing the basement roof, the bearing capacity of the basement roof will be significantly improved, thereby meeting the requirements of material transportation and storage yard. This not only ensures the smooth progress of the construction process, but also ensures the safety and stability of the basement structure. Therefore, in the process of basement construction, reinforcing the roof is a vital task.

[0003] The traditional basement top support system widely uses a fastener-type full-floor scaffolding. The structure is composed of multiple steel pipes connected by fasteners in the longitudinal, transverse and vertical directions to ensure the stability and load-bearing performance of the structure. In order to achieve the top support effect, the construction workers need to manually rotate the top support until it is in close contact with the top of the floor slab, thereby applying preload force. However, in actual construction operations, the top support can often only be adjusted to a position roughly flush with the floor slab. At this time, the top support system cannot immediately play its due supporting role, and it is necessary to wait for the structural floor slab to undergo a certain degree of settlement deformation before it can gradually play its supporting effect. This delayed support effect not only affects the progress of the construction, but also may cause the structural floor slab to deform during the top support process. In severe cases, it may even cause quality problems such as cracking of the floor slab, posing a potential threat to the overall structural safety of the basement. Therefore, the improvement and optimization of the traditional basement top support system has important practical significance and application value.

[0004] To this end, we propose a roof support device for a basement. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides a top-return support device for a basement.

[0006] In order to achieve the above-mentioned invention object, the technical solution adopted by the utility model is:

[0007] A top-return support device for a basement comprises: a top rod, an upper top plate is arranged on the bottom circumference, and a buffer is arranged between the top end of the top rod and the building top plate; a bottom rod, a lower top plate is arranged on the top circumference, and a buffer is also arranged between the bottom end of the bottom rod and the building floor; a lifting mechanism is arranged between the upper top plate and the lower top plate, the lifting mechanism is used to lift the top rod, the lifting mechanism is fixed to the lower top plate by a limiting structure, and the limiting structure is used to prevent the lifting mechanism from sliding on the lower top plate and the upper top plate.

[0008] By providing a top rod and a bottom rod and arranging a lifting mechanism between the top rod and the bottom rod to realize the lifting of the top rod, prestress is directly applied to the basement top plate, and the supporting effect on the basement top plate can be achieved during installation without waiting for the basement top plate to settle, thereby reducing the time waiting for its supporting effect to take effect, shortening the construction period, and improving construction efficiency. In addition, fixing the lifting mechanism on the lower top plate through a limiting structure can prevent the lifting mechanism from deviating when lifting the top plate, causing the lifting mechanism to slip, thereby improving the safety of the device.

[0009] It is further defined that the lifting mechanism is a jack; using a jack as the lifting mechanism is convenient in material selection, has a large lifting weight, and has a low cost of use.

[0010] It is further defined that the upper top plate and the lower top plate are each provided with at least three lifting mechanisms, and the number of the lifting mechanisms matches the number of the lower top plates; providing at least three lifting mechanisms on the circumferential surface of the top rod and the bottom rod can ensure that the circumferential force on the top rod and the bottom rod is more uniform, and the structure is more stable than that of two lifting mechanisms arranged relatively to each other.

[0011] It is further defined that the top surface of the upper top plate is provided with an upper reinforcing plate connected to the top rod, and the bottom surface of each lower top plate is provided with a lower reinforcing plate connected to the bottom rod, and the upper reinforcing plate and the lower reinforcing plate are both in the shape of a right-angled triangle; the provision of the upper reinforcing plate and the lower reinforcing plate can further enhance the strength of the upper top plate and the lower top plate, and prevent the upper top plate and the lower top plate from bending and tilting due to excessive force during the lifting process.

[0012] It is further defined that the limiting structure includes a limiting seat and a piston cylinder, the limiting seat is in the shape of a box with an opening at the top, the inner diameter of the limiting seat matches the outer diameter of the base of the jack, the limiting seat is fixed on the lower top plate, the piston cylinder is fixed on the bottom surface of the upper top plate corresponding to the limiting seat, and the inner diameter of the piston cylinder matches the outer diameter of the piston head of the jack; by setting the limiting seat and the piston cylinder, the base of the jack is placed in the limiting seat, the limiting seat can effectively prevent the base of the jack from sliding on the lower top plate during lifting, and placing the piston head of the jack in the piston cylinder can also prevent the piston rod of the jack from deviating on the upper top plate during lifting, thereby improving the safety and stability of the lifting device.

[0013] It is further defined that the buffer is a wooden board; the buffer is made of wooden boards, which are easy to select and have very good effects, and the cost is also lower.

[0014] It is further defined that a plurality of guide cylinders are arranged on the circumference of the bottom rod, and guide rods matching the guide cylinders are arranged vertically on the circumference of the top rod. When the guide rods are fully inserted into the guide cylinders, the bottom end of the top rod contacts the top end of the bottom rod, and the guide cylinders and the lower top plate are staggered, and the guide rods and the upper top plate are staggered. Providing the guide cylinders and the guide rods is beneficial for positioning the top rod and the bottom rod during installation so that the upper top plate and the lower top plate are aligned, and can avoid the top rod from shifting and tipping over when the top rod does not generate prestress on the basement top plate, which is more conducive to installation.

[0015] The beneficial effects of the utility model are as follows: by arranging the top rod, the bottom rod and the lifting mechanism, the basement top plate can be effectively prestressed immediately, and a support effect can be provided before the basement top plate settles, the construction period is shortened, and the construction efficiency is improved.
