Description

Technical Field

[0001] The utility model belongs to the technical field of building engineering construction, and in particular relates to a support device with adjustable horizontal height. Background Art

[0002] During the construction process of a building project, when the bottom formwork of a concrete structure is laid, it is necessary to adjust the height according to the elevation of the design drawing to meet the requirements of the drawing. This is especially common in the construction of structures such as pier cap beams and tie beams. During the construction process, the height adjustment device must also have sufficient strength and rigidity to withstand the load of the upper formwork and concrete, and must not be easily damaged or slipped, affecting the safety of the construction process and the quality of the structural construction.

[0003] At present, most construction sites use jacks as devices to adjust the elevation. However, under continuous load pressure, they are prone to oil pressure leakage and mechanical fatigue, resulting in changes in the elevation of the bottom formwork and affecting the construction quality of the physical structure. At the same time, the jack as a whole is also very easy to tip over under the action of vibration, which is also very detrimental to the safety of the operation process. Some provinces, cities and autonomous regions have successively banned the use of jacks to adjust the elevation of the formwork to reduce the safety risks brought by the structure itself. Utility Model Content

[0004] The utility model aims to solve the problem of adjusting the elevation of the existing bottom formwork of a construction project upward and downward, and uses a conventional and simple structural device to effectively solve the problem of deformation and overturning that is easy to occur during the use of the adjustment device, and proposes a reliable and simple device.

[0005] The technical solution adopted by the utility model to solve the above-mentioned problems is: a support device with adjustable horizontal height, characterized in that it includes an upper adjustment seat, a side frame, a base, and an adjusting screw; the upper adjustment seat includes a seat plate and a convex body connected to the bottom of the seat plate, the cross-section of the convex body is an isosceles trapezoid, and is connected to the base through a vertical screw; the side frames are located on the left and right sides of the vertical screw, one each, with a right-angled trapezoidal cross-section, arranged in a mirror image, and connected through a horizontal screw, and both sides of the side frames are connected with limit grooves parallel to the horizontal screw, which are used to limit the side frames to move only in the lateral direction of the device; the oblique angle of the right-angled trapezoid and the bottom angle of the convex body add up to 90°, and a Y-shaped side clamp is formed between the inner edge of the right-angled trapezoid and the vertical screw and the convex body.

[0006] Both ends of the vertical screw rod are connected to the convex body through vertical screw rod nuts, the upper end is a movable double nut, and the lower end is a fixed nut.

[0007] Both ends of the horizontal screw are connected with movable horizontal screw nuts.

[0008] The screw rod and nut are precision-rolled threaded steel and matching nuts.

[0009] The bottom of the side frame is movably connected to the base.

[0010] The limiting grooves are made of various types of steel, with two at the top and two at the bottom, and are respectively connected to the upper adjusting seat and the base.

[0011] The utility model utilizes the principle of clamping and jacking. Through continuous clamping of the two side frames, the upper adjusting seat arranged in the middle is forced to squeeze upwards, offsetting the pressure load transmitted from the upper part; the designed locking of the screw and nut ingeniously offsets the vertical load with a horizontal force; the overall device is designed as a rectangular body, not easy to overturn and damage, with sufficient strength and stiffness, and is simple to operate and highly reliable.

[0012] The materials required for processing the device of the utility model are relatively common on-site, convenient to obtain materials, with a simple structure and can be processed and manufactured on-site by oneself; the device effectively realizes the adjustment of the horizontal height and has sufficient strength and stiffness; the device has a simple structure, can be reused, and both installation and disassembly are relatively simple.
