Description

Technical Field

[0001] The utility model belongs to the technical field of foundation pits, and relates to a waist beam of a foundation pit, in particular to an installation structure of the waist beam of a foundation pit. Background Art

[0002] In the construction of foundation pit, in order to ensure the stability of the foundation pit structure and safe construction, a support system is usually set up in the foundation pit for support. The support system includes waist beams and steel supports. The waist beams are fixedly installed on the two side walls of the foundation pit, and several steel supports are fixedly installed at intervals between the corresponding waist beams. There are the following problems:

[0003] 1. Adjacent waist beams are connected by on-site welding. The connection quality of the waist beams has a great impact on the safety of the foundation pit. The on-site welding work is limited by the internal space of the foundation pit, which makes the construction inconvenient, the efficiency is low, and the welding quality is difficult to guarantee;

[0004] 2. The bending stress at different positions on the waist beam is different, and the force is uneven. The support spacing is fixed, which does not match the waist beam well. The waist beam has the smallest bending stress without reinforcement, which is prone to structural damage and poses a safety hazard.

[0005] Therefore, we propose an installation structure of foundation pit waist beam to solve the above problems. Utility Model Content

[0006] The utility model aims to overcome the deficiencies of the prior art and provide a foundation pit waist beam installation structure which has a firm installation and a simple structure.

[0007] To solve the above problems, the technical solution of the utility model is:

[0008] A foundation pit waist beam installation structure, a plurality of supports are fixedly installed on the waist beam at intervals, comprising:

[0009] A connecting plate assembly is fixedly mounted on the end of the waist beam and is suitable for connecting adjacent waist beams together;

[0010] There is a spacing distance between the support and the connecting plate assembly at the end of each waist beam section, which is suitable for reinforcing the waist beam;

[0011] The connecting plate assembly comprises a first connecting plate and a second connecting plate. The outer end surfaces of the first connecting plate and the second connecting plate are respectively fixedly mounted on the adjacent waist beam ends. The relative inner ends of the first connecting plate and the second connecting plate are fixedly buckled and mounted together.

[0012] In a further embodiment, at least one protruding hook is formed on the first connecting plate, and a corresponding hanging groove is formed on the second connecting plate.

[0013] In a further embodiment, the hook and the hanging groove are respectively extended to the top end of the first connecting plate and the second connecting plate, and are suitable for insertion.

[0014] In a further embodiment, a corresponding plurality of bolt holes are formed on at least two sides of the first connecting plate and the second connecting plate.

[0015] In a further embodiment, the spacing distance is the distance between the first connecting plate or the second connecting plate and the point where the bending stress at both ends of the waist beam is the smallest.

[0016] In a further embodiment, both ends of the waist beam are configured as first connecting plates, and both ends of adjacent waist beams are configured as second connecting plates.

[0017] In a further embodiment, one end of the waist beam is configured as a first connecting plate, and the other end of the waist beam is configured as a second connecting plate.

[0018] In a further embodiment, the first connecting plate and the second connecting plate are both made of steel.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] 1. Both ends of the waist beam of the installation structure are fixedly installed with connecting plate assemblies, and the connecting plate assemblies include a first connecting plate and a second connecting plate. The first connecting plate, the second connecting plate and the waist beam can be welded together in advance, eliminating the on-site welding steps and ensuring the welding quality; a plurality of bolt holes are arranged on the first connecting plate and the second connecting plate at intervals, and the first connecting plate and the second connecting plate are fixedly installed together by bolts, which is convenient and quick, and improves the construction efficiency.

[0021] 2. This installation structure has the smallest bending stress at both ends of the waist beam, which is usually 1m away from the ends. Fixing the installation support here for reinforcement can effectively improve the strength of the waist beam, avoid safety hazards, and make it firm and stable.

[0022] 3. The first connecting plate of the installation structure is provided with a protruding hook, and the second connecting plate is provided with a corresponding hanging groove, and the hook and the hanging groove extend to the top end of the first connecting plate and the second connecting plate respectively, so that the insertion can be completed when the hoisting falls, which is convenient and quick; the concave-convex structure formed by the hook and the hanging groove forms a double connection with the bolt, which improves the connection quality of the waist beam and ensures stability and reliability during use.
