Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an external wall structure in which the partition wall between foundation pits utilizes piles for load-bearing. Background Technology

[0002] In traditional construction projects, the intermediate partition wall between different foundation pits, which is often between different construction sections, is also called the outer wall of two different construction sections. The piles of the outer wall of the intermediate partition wall in this part are often not removed. The outer walls on both sides directly cover the retaining piles. The two construction sections (foundation pits) are often connected by a connecting passage.

[0003] A search revealed Chinese patent CN209227548U, which discloses a buttress-type sidewall combined inclined bracing reinforced pile support structure. The structure includes a foundation pit and a row of support piles positioned between the foundation pit and the soil. Weights are placed on the soil. A basement is constructed within the foundation pit, comprising a floor slab and basement sidewalls positioned near the support piles. Several buttress columns are vertically arranged on the side of the basement sidewalls near the support piles, abutting against the support piles. Several supporting beams are detachably installed in the middle of each buttress column. A support device for balancing the lateral loads on the basement sidewalls is provided on the side of the basement sidewalls facing away from the support piles. This utility model can reinforce pile structures exceeding their original design load, allowing the project to continue until successful completion.

[0004] Based on the above search and existing technology, the findings were as follows:

[0005] The aforementioned search patents state that the external walls and maintenance piles between different foundation pits (sections) are not connected. Therefore, the external walls need to be designed with larger cross-sections and reinforcement according to normal stress and load calculations, and buttress columns need to be installed. If the buttress columns are not constructed properly, they may cause uneven stress or connection failure, affecting the overall stability. Therefore, there are certain limitations. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes an external wall structure in which the partition wall between foundation pits is supported by piles, which can reduce the cross-section and reinforcement of the external wall and eliminate the buttress columns, and use the piles to jointly resist the buoyancy of the basement.

[0007] The technical solution to achieve the purpose of this utility model is: an external wall structure for the partition wall between foundation pits that utilizes piles for load-bearing, including multiple piles, and also including;

[0008] The floor slab is fixedly installed on top of the piles;

[0009] The concealed beams are provided in multiple forms and are fixedly installed on the piles.

[0010] Preferably, a central partition wall is fixedly installed between the piles, and the two ends of the hidden beam are located inside the central partition wall.

[0011] Preferably, multiple main reinforcing bars are fixedly installed on the outside of the concealed beam, and multiple stirrups are welded to the outside of the main reinforcing bars. Supporting steel is fixedly installed on both sides of the outside of the pile.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] Firstly, this utility model eliminates the need for buttress columns in the central partition wall by installing a hidden beam above and below each row of piles on each floor, thereby reducing the cross-section and reinforcement of the central partition wall. At the same time, the hidden beams connect the central partition wall and the piles into a stable anti-buoyancy structure, improving both safety and economy.

[0014] Secondly, this utility model adds supporting steel to improve the bearing capacity of the piles and the durability of the building. In addition, the hidden beam at the top of the piles needs to extend to the adjacent foundation pit support structure to form a continuous closed frame and enhance the overall resistance to lateral displacement.

[0015] This solves the problem that the existing external walls and maintenance piles between different foundation pits (sections) are not connected, so the external walls need to be designed with larger cross sections and reinforcement according to normal stress and load calculations, and buttress columns need to be set. If the buttress columns are not constructed properly, they can easily lead to uneven stress or connection failure, affecting the overall stability. Attached Figure Description

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved external wall structure for the partition wall between foundation pits, utilizing piles for load-bearing. The technical solution of this utility model is as follows:

[0024] like Figures 1-3 As shown, an external wall structure for the partition wall between foundation pits using piles for load-bearing includes multiple piles 1. The pile 1 support system forms a retaining structure with high overall rigidity through the dense arrangement of the piles, with outstanding bending resistance, which can effectively control the deformation of the foundation pit sidewall. It also includes:

[0025] Floor slab 2 is fixedly installed on top of pile 1 and anchored to pile 1 with steel bars to improve structural stability;

[0026] Hidden beam 3, multiple hidden beams 3 are provided and fixedly installed on pile 1. Hidden beam 3 improves the lateral stiffness of pile 1 and suppresses pile displacement through dense reinforcement.

[0027] Furthermore, a central partition wall 4 is fixedly installed between the piles 1, and the two ends of the hidden beam 3 are set inside the central partition wall 4 to form a continuous rigid system that effectively resists earthquake or eccentric loads.

[0028] Furthermore, multiple main reinforcement bars 7 are fixedly installed on the outside of the hidden beam 3, and multiple stirrups 6 are welded to the outside of the main reinforcement bars 7. Supporting steel bars 5 are fixedly installed on both sides of the outside of the pile 1 to enhance the stability of the connection between the various structures and improve the durability of the pile 1.

[0029] The specific working method is as follows: Construction can be carried out on the basement floor slab between different foundation pits (sections). First, the soil on the surface of the pile 1 is cleaned, and the junction of the pile 1 and the hidden beam 3 is roughened. The hidden beam 3 is constructed by installing rebars at a height of 500mm from the ground on both sides of the bottom of the pile 1. The main rebar 7 of the hidden beam 3 has a diameter of 25mm and is anchored 300mm into the pile 1. The stirrups 6 have a diameter of 10mm and a spacing of 100mm. The hidden beam 3 is anchored into the central partition wall 4, and the rebars of the hidden beam 3 and the central partition wall 4 are mutually anchored. The hidden beam 3 is constructed at the top of the pile 1 at the floor position. The hidden beam 3 is set up for each pile 1 of the floor according to the above method, and the rebars are mutually anchored. The rebars of the floor slab 2 are bent and anchored into the central partition wall 4 by 10d, and the rebars of the floor beams are bent and anchored into the central partition wall 4 by 35d. After all the rebars are tied, the concrete is poured.
