Description

Technical Field

[0001] The present invention relates to the technical field of temporary construction structures, and particularly relates to a hydraulic leveling device and a leveling system for construction support. Background Art

[0002] As a key technology in modern building structure construction, the temporary support structure is mainly used in scenarios such as concrete pouring, steel structure hoisting, and large-span space construction, playing a core role in temporary load transfer, structural stability guarantee, and construction safety control. With the continuous development of the construction industry, the technology of temporary support structures is rapidly developing towards the direction of intelligence, greenness, and high efficiency. As a result, innovative structures put forward higher requirements for the mechanical properties and construction accuracy of the support system. The existing technology needs to be further optimized to adapt to complex working conditions. At the same time, accidents such as the collapse of high formwork still occur from time to time, and it is necessary to strengthen monitoring technology to improve the safety management level.

[0003] Currently, there are two categories of safety management measures for temporary support structures as follows: First, reasonable design and construction plans are made. According to the actual situation of the project, such as the structure type, load size, construction environment, etc., a reasonable design and construction plan for the temporary support structure is formulated. At the same time, the construction load is strictly controlled according to the design requirements to avoid overloading. When stacking building materials, formwork, construction machinery and tools and other materials on structures such as floors and roofs, they should be reasonably distributed to prevent local overloading from causing the support structure to become unstable. Second, sensors, data acquisition devices, and automated analysis software are used to monitor the deformation, stress, etc. of the temporary support structure in real time. By monitoring parameters such as the axial force, horizontal displacement, settlement of the vertical poles, and the inclination of the structure, potential safety hazards of the temporary support structure can be detected in a timely manner.

[0004] However, there are the following problems with the current temporary support safety management measures: First, the construction temporary support structure is usually fabricated on the construction site. Due to the large errors in on-site fabrication, there is a large deviation between the stress condition of the support structure and the theoretical calculation model. Seriously, it will cause a large change in the stress transmission path of some stresses, and the tensile and compressive relationships of the truss or lattice column members will be reversed, thus posing a certain risk to the safety and stability of the temporary support structure. Second, in the existing risk management measures for construction temporary support structures, the adjustment of the monitoring results of risk points has a certain lag. When abnormal stress conditions, large deformations of members, large settlement displacements of the overall support, etc. are monitored in the temporary support structure, the adjustment of the temporary support often requires unloading the upper load before it can be carried out, which increases the risk of collapse of the temporary support structure. Summary of the Invention

[0005] In view of the above problems, a construction support hydraulic leveling device and a leveling system are provided herein. The aim is to ensure stable connection at the support nodes of the upper structural members to be installed by directly installing the device on the top of the vertical members of the temporary support without adjusting the layout of the original support system and without setting additional connection nodes.

[0006] The specific technical solutions are as follows: The first aspect of the present invention is to provide a construction support hydraulic leveling device, which includes: a load distribution pressure plate I, a load distribution pressure plate II, a preloading shock pad, an anti-slip elastic support pad, and a plurality of hydraulic struts. The hydraulic struts are located between the load distribution pressure plate I and the load distribution pressure plate II. The load distribution pressure plate II is installed above the load distribution pressure plate I through the hydraulic struts. The preloading shock pad is installed between the load distribution pressure plate I and the load distribution pressure plate II. The load distribution pressure plate I is installed on the steel support column.

[0007] Furthermore, the leveling device further includes a pressure sensing component for detecting pressure, and the pressure sensing component is installed between the preloading shock pad and the load distribution pressure plate II.

[0008] Furthermore, a limit card slot is installed at the bottom of the load distribution pressure plate I, and the load distribution pressure plate I is clamped on the steel support column through the limit card slot.

[0009] Furthermore, the limit card slot is welded to the bottom of the load distribution pressure plate I.

[0010] Furthermore, the limit card slot is in the shape of a hollow cylinder, and the top of the limit card slot is welded to the bottom of the load distribution pressure plate I.

[0011] Furthermore, the base of the hydraulic strut is welded to the load distribution pressure plate I, and the top of the hydraulic strut is welded to the load distribution pressure plate II.

[0012] Furthermore, there are at least three hydraulic struts.

[0013] Furthermore, the pressure sensing component includes a pressure sensor and a pressure gauge. The pressure sensor is installed on the side of the load distribution pressure plate II facing away from the load distribution pressure plate I, and the pressure gauge is electrically connected to the pressure sensor.

[0014] Furthermore, the pressure sensor is installed on the side of the load distribution pressure plate II facing away from the load distribution pressure plate I through structural adhesive.

[0015] The second aspect of the present invention is to provide a construction support hydraulic leveling system, which includes a plurality of the above-mentioned construction support hydraulic leveling devices.

[0016] The beneficial effects of the above solutions are: 1) Compared with the traditional temporary construction support leveling components, the construction support hydraulic leveling device provided by the present invention can avoid the problems of indirect force transmission path and non-vertical leveling support caused by construction errors during the support processing by adjusting the hydraulic support rods in real time, thereby ensuring the stable connection at the support node of the upper structural component to be installed; 2) In order to solve the problem that the actual stress conditions of the traditional support system are unclear and inconsistent with the stress conditions of the structural calculation results, the present invention provides a construction support hydraulic leveling device that can be used simultaneously by multiple units, so as to adjust the pressure of the tops of multiple support columns in a linked manner, thereby realizing the adjustment of the force distribution at different supports, so that the support stress conditions correspond to the structural calculation results, thereby ensuring the reliability and safety of the support structure.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0022] like Figure 1 , Figure 2As shown in the figure, the construction support hydraulic leveling device provided in the embodiment of the present invention includes: a load distribution pressing plate 2, a load distribution pressing plate 1, a preloading shock-absorbing pad 4, an anti-slip elastic support pad 5, and four hydraulic struts 3. The hydraulic struts 3 are located between the load distribution pressing plate 2 and the load distribution pressing plate 1. The load distribution pressing plate 1 is installed above the load distribution pressing plate 2 through the hydraulic struts 3 (the base of the hydraulic strut 3 is welded to the load distribution pressing plate 2, and the top of the hydraulic strut 3 is welded to the load distribution pressing plate 1). The preloading shock-absorbing pad 4 is installed between the load distribution pressing plate 2 and the load distribution pressing plate 1, and the load distribution pressing plate 2 is installed on the steel support column 8.

[0023] In the present invention, by adjusting the hydraulic struts 3, the angles between the load distribution pressing plate 1 and the anti-slip elastic support pad 5 and the supported structural member 10 are controlled, so as to adjust the angle of the support, and ensure the tight connection between the elastic support pad 5 and the supported structural member 10.

[0024] Compared with the traditional construction temporary support leveling component, the construction support hydraulic leveling device provided by the present invention can avoid problems such as non-direct force transmission path and non-perpendicular leveling support caused by construction errors in the bracket processing process by adjusting the hydraulic struts 3 in real time, so as to ensure the stable connection at the support node of the upper structural member to be installed.

[0025] Further, as Figure 2 shown, a limit card slot 9 is installed at the bottom of the load distribution pressing plate 2 in the present invention, and the load distribution pressing plate 2 is clamped on the steel support column 8 through the limit card slot 9. Specifically, the above-mentioned limit card slot 9 can be a plurality of plate-shaped structures, which can be welded to the bottom of the load distribution pressing plate 2. After welding, the load distribution pressing plate 2 is clamped on the steel support column 8 by using the limit card slot 9; of course, the limit card slot 9 can also be in the shape of a hollow cylinder, the top of the limit card slot 9 is welded to the bottom of the load distribution pressing plate 2, and after welding, the load distribution pressing plate 2 is clamped on the steel support column 8 by using the limit card slot 9 and the load distribution pressing plate 2 itself.

[0026] Further, as Figure 2 shown, in order to obtain the stress condition of the bracket in real time, the leveling device in the present invention may further include a pressure sensing component for detecting pressure, which may include a pressure sensor 6 and a pressure gauge 7. The pressure sensor 6 is installed on the side of the load distribution pressing plate 2 facing away from the load distribution pressing plate 1 through structural adhesive. The pressure gauge 7 is electrically connected to the pressure sensor 6. Under the above structure, data is measured in real time through the pressure sensor 6, and the reading of the pressure gauge 7 is read. Then, by adjusting the hydraulic struts 3, the stress condition of the bracket is made to correspond to the structural calculation result, so as to ensure the reliability and safety of the support structure.

[0027] As Figure 3As shown, in the present invention, multiple construction support hydraulic leveling devices can be combined to form a leveling system. When in use, the system adjusts the pressure of the tops of multiple support columns by adjusting the hydraulic support rods 3, and adjusts the force distribution between each support by reading the reading of the pressure gauge 7, so that the force condition of the support corresponds to the structural calculation result, ensuring the reliability and safety of the support structure.

[0028] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention.
