Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of foundation reinforcement, in particular to a foundation reinforcement structure used for adding elevators to old buildings. Background Art
[0002] Due to their age, the foundation structures of older buildings often fail to accommodate future elevator installations, necessitating specialized reinforcement to meet new load requirements. While traditional foundation reinforcement methods, such as foundation expansion and pile reinforcement, can improve the bearing capacity of the foundation to a certain extent, they are complex, costly, and time-consuming to construct, and they significantly impact the surrounding environment. Therefore, developing a foundation reinforcement structure that is both cost-effective and efficient, easy to construct, and has minimal environmental impact is crucial. Utility Model Content

The frame is quickly formed by square tubes, anchor rods and positioning bases, and is poured as a whole using concrete. The construction speed is fast, the structure is stable, and the pit settlement capacity is strong.
[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:
[0005] The utility model is a foundation reinforcement structure for adding elevators to old buildings, comprising a plurality of square tubes and anchor rods arranged in a rectangular array and inserted into a soil layer; a positioning base is plugged and installed on the upper end of each anchor rod; the square tubes are placed on the plurality of positioning bases arranged in the rectangular array in horizontal and vertical layers; and the plurality of positioning bases and the square tubes are connected as a whole through concrete.
[0006] As a preferred technical solution of the present invention, the square tube is connected to the positioning base by bolts and nuts; the side surface of the square tube is provided with a plurality of groups of through holes along its length for passing the bolts and nuts.
[0007] As an optimal technical solution of the present invention, the positioning base includes a cylinder inserted into the inner cavity of the upper end of the anchor rod; a rectangular plate is fixed to the outer wall of the upper end of the cylinder; four pairs of vertically arranged rectangular tubes are fixed on the upper surface of the rectangular plate in a cross arrangement; a row of vertically arranged long circular holes are opened on the outer wall of the rectangular tube.

[0009] The utility model has the following beneficial effects:
[0010] 1. This utility model significantly enhances the bearing capacity of the foundation by anchoring the rods deep into the soil, utilizing the friction and end resistance of the soil to provide additional support. The concrete connection ensures a strong bond between the square tubes, the positioning base, and the anchor rods, giving the entire reinforced structure excellent durability and aging resistance, ensuring long-term and stable operation. The combination of the square tubes, positioning base, and anchor rods forms a stable framework that effectively disperses and transfers the load of the superstructure to the soil, improving the stability of the entire structure.

[0023] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention. Specific embodiment one:
[0025] See also Figure 1-5 As shown, the utility model is a foundation reinforcement structure for adding elevators to old buildings, comprising a plurality of square tubes 1 and anchor rods 2 arranged in a rectangular array and inserted into the soil layer. The anchor rods 2 penetrate into the soil layer and provide additional support by using the friction and end resistance of the soil, which significantly enhances the bearing capacity of the foundation. A positioning base 3 is installed on the upper end of each anchor rod 2. Square tubes 1 are placed horizontally and vertically on the plurality of positioning bases 3 arranged in a rectangular array. The plurality of positioning bases 3 are connected to the square tubes 1 as a whole through concrete 4. In this embodiment, the anchor rods 2 are evenly spaced and arranged in a grid-like manner and inserted into the soil layer below where the elevator needs to be installed. A stable frame structure is formed by combining the square tubes 1, the positioning bases 3 and the anchor rods 2, and they are connected as a whole using concrete 4, which effectively disperses and transfers the load of the upper structure to the soil layer, thereby improving the stability of the overall structure. The concrete 4 connection ensures a firm connection between the square tubes 1 and the positioning bases 3, so that the entire reinforcement structure has good durability and anti-aging properties, and can function stably for a long time.
[0026] Among them, the square tube 1 and the positioning base 3 are connected by bolts and nuts 5. Several groups of round through holes 11 for passing the bolts and nuts 5 are opened on the side of the square tube 1 along its length direction. Among them, the positioning base 3 includes a cylinder 31 that is inserted into the inner cavity of the upper end of the anchor rod 2. A rectangular plate 32 is fixed to the outer wall of the upper end of the cylinder 31. Four pairs of vertically arranged rectangular tubes 33 are fixed on the upper surface of the rectangular plate 32 in a cross arrangement. A row of vertically arranged long circular holes 34 are opened on the outer wall of the rectangular tube 33. The design of the long circular holes 34 facilitates the installation of the square tube 1 on the positioning base 3 using bolts and nuts 5. The combined structure of the positioning base 3 and the anchor rod 2 is relatively simple, and the subsequent installation process of the square tube 1 is relatively convenient, which can shorten the construction period and reduce the impact on residents' lives.
[0027] In order to facilitate the adjustment of the positioning base 3 to the same height for the subsequent installation of the square tube 1, at least four threaded through holes 35 are opened on the upper surface of the rectangular plate 32. Bolts pass through the threaded through holes 35 and press against the upper end of the anchor rod 2 to support the positioning base 3.
[0028] When installing anchor rods 2, their length and number are adjusted according to actual geological conditions to accommodate varying soil types and load-bearing requirements, resulting in a highly adaptable solution. Compared to traditional large-scale foundation reinforcement methods, this solution offers lower costs, faster construction, and higher economic benefits. The overall construction process also generates minimal noise and vibration, minimizing disruption to the surrounding environment and aligning with the principles of green building.
