Abstract
Description
Technical Field
[0001] This utility model relates to the field of geotechnical engineering support technology, specifically to a flexible connection structure between a building frame column and anti-slide piles. Background Technology
[0002] In recent years, with the continuous growth of my country's economic strength, the country has attached great importance to infrastructure construction. Steep slopes have appeared in large numbers in many fields such as highway engineering and construction engineering. However, landslide accidents caused by these slopes are frequent. Slope instability is particularly common in the western loess region. Its instability may block roads, disrupt traffic, and even threaten people's lives and property. It is a serious geological disaster. This not only affects the quality of engineering construction, but also further affects people's lives and property. Therefore, slope problems must be given sufficient attention in engineering construction.
[0003] For slopes with good stability, excellent geological conditions, and low risk of instability, only minor modifications are needed before they can be put into use. However, slopes with poor engineering properties, prone to damage, and posing safety hazards must be supported and reinforced. Slope support refers to the measures taken to support, reinforce, and protect slopes to ensure the safety of the slope and its environment. Commonly used support structures include series retaining walls, pile-slab walls, frame lattice structures, and combinations thereof with prestressed anchor cables, prestressed anchor rods, prestressed anchor plates, and prestressed anchoring plates.
[0004] However, in the process of developing and constructing mountain cities, the layout of slope protection structures and main building structures often conflicts due to limited site space, which exacerbates the problem of tight construction land. Utility Model Content
[0005] The present invention aims to provide a flexible connection structure between building frame columns and anti-slide piles to solve the problem of land shortage caused by the conflict between the existing slope protection structure and the layout of the main building structure.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a flexible connection structure between a building frame column and an anti-slide pile, comprising an anti-slide pile installed on a slope, a frame column connected to the top of the anti-slide pile, and a flexible connection structure between the frame column and the anti-slide pile. The flexible connection structure includes a first connecting plate fixed to the top of the anti-slide pile, a second connecting plate fixed to the bottom of the frame column, and a flexible connecting block connecting the first connecting plate and the second connecting plate.
[0007] The beneficial effects of this scheme are as follows: placing the building frame columns on top of the slope anti-slide piles and connecting the two through a flexible connection structure maximizes the use of the building's vertical load to enhance slope stability, releases valuable land space, and provides a new technical path for the intensive construction of mountain cities under complex terrain conditions.
[0008] To address the layout conflict between the slope protection structure and the main building structure, instead of the traditional avoidance method, the building frame columns were placed on top of the anti-slide piles. This allowed some of the building load to act directly on the anti-slide piles as vertical forces, avoiding excessive lateral earth pressure on the anti-slide piles from the building load. While ensuring that the shear strength of the pile body met the requirements, the bending strength of the anti-slide piles was increased, fully releasing the bending performance of the anti-slide piles and saving construction land.
[0009] This solution has good application value for projects with similar construction sites where there are differences in terrain elevation and layout conflicts between slope support structures and building structures. It provides an effective technical approach to solve key problems in the intensive construction of mountainous cities.
[0010] Preferably, as an improvement, a first fastener is provided between the first connecting plate and the anti-slide pile, and a second fastener is provided between the second connecting plate and the frame column.
[0011] The beneficial effects are: by setting fasteners, the stability of the connection structure can be enhanced, ensuring a firm connection between the anti-slip piles and the frame columns, thereby improving the overall load-bearing capacity and anti-slip ability of the structure.
[0012] Preferably, as an improvement, the number of first and second fasteners is several.
[0013] Preferably, as an improvement, the fastener is fixedly connected to the connecting plate.
[0014] Preferably, as an improvement, the size of the second connecting plate is larger than the cross-sectional size of the frame column.
[0015] The beneficial effects are: it can provide a larger connection area, thereby enhancing the rigidity and stability of the connection parts.
[0016] Preferably, as an improvement, the connecting plate is made of steel plate.
[0017] The beneficial effect is that the fasteners are made of steel bars.
[0018] Preferably, as an improvement, the flexible connecting block is made of rubber.
[0019] The beneficial effect is that since the lower anti-slide piles may produce horizontal displacement towards the open surface, rubber bearings are installed to prevent the frame column and the support pile from producing the same horizontal deformation.
[0020] The use of rubber material avoids the problem that rigid supports would cause the frame column to have the same horizontal displacement when the lower anti-slide piles have a large horizontal displacement, while sliding supports would also avoid the problem that the frame column and anti-slide piles would have a large relative horizontal displacement. Attached Figure Description
[0021] Figure 1 This is a schematic diagram of the overall structure of an embodiment of the present utility model. Detailed Implementation
[0022] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: anti-slide pile 1, first steel plate 11, first reinforcing bar 12, frame column 2, second steel plate 21, second reinforcing bar 22, and connecting block 3.
[0023] Example like Figure 1 The diagram shows a flexible connection structure between a building frame column 2 and an anti-slide pile 1, comprising several anti-slide piles 1 vertically fixed to the slope. The anti-slide piles 1 are made of cement casting. A first steel plate 11 is pre-embedded at the top of the anti-slide pile 1. The first steel plate 11 is a Q355 steel plate with a thickness of 20mm. Six first reinforcing bars 12 are vertically installed inside the anti-slide pile 1 during casting. The first steel plate 11 has connection holes for the first reinforcing bars 12 to pass through. The connection holes between the first reinforcing bars 12 and the first steel plate 11 are connected by through-hole plug welding. After the first reinforcing bars 12 and the first steel plate 11 are welded, the top of the first steel plate 11 is ground flat.
[0024] It also includes a frame column 2 located above the anti-slide pile 1. The frame column 2 is also cast with cement. A second steel plate 21 is pre-embedded at the bottom of the frame column 2. The second steel plate 21 is also a Q355 steel plate with a thickness of 20mm. The size of the second steel plate 21 is larger than the size of the bottom surface of the frame column 2. In addition, the size of the first steel plate 11 is the same as that of the second steel plate 21. Before the frame column 2 is poured, six second reinforcing bars 22 are vertically installed inside. The second steel plate 21 also has connecting holes for the second reinforcing bars 22 to pass through. The second steel plate 21 is also welded by through-hole plug welding. After welding, the bottom end of the second steel plate 21 is ground flat. When the frame column 2 is connected to the top of the anti-slide pile 1, a connecting block 3 is set between the first steel plate 11 and the second steel plate 21. The connecting block 3 is made of plate-type neoprene rubber material. In addition, steel edges are fixed on both the upper and lower sides of the connecting block 3. The upper and lower sides of the connecting block 3 are fixed to the second steel plate 21 and the first steel plate 11 respectively by welding. When the connecting block 3 is installed, phenolic resin to prevent rubber aging is applied around the connecting block 3 and foam plastic is bonded.
[0025] After the anti-slide pile 1 is completed, the pile top displacement should be monitored. The upper frame column 2 can only be constructed after the displacement stabilizes. The design should be notified for confirmation before construction. The displacement change is greatest within one year after pile construction, so the frequency of monitoring the pile top and column displacement should be increased. The slope may also experience excessive displacement due to extreme conditions such as rainstorms in the later stage. Therefore, the deformation of the support should be inspected after rainstorms, and regular monitoring and inspection should be carried out. After installation, an early warning should be issued if the pile top displacement exceeds 20mm. During the installation and use of the connecting block 3, contact with oily substances such as grease and other substances harmful to rubber should be avoided.
