Description

Technical Field

[0001] The utility model relates to the technical field of internal hole support of foundation, in particular to an internal hole support structure of foundation. Background Art

[0002] At present, the well-known formwork support system is the scaffold support, and the following problems exist in the actual application process: (1) The members at the joints are eccentrically connected, and the load and internal force are transmitted by the anti-sliding force, thus reducing its bearing capacity; (2) The connection quality of the fastener joints is significantly affected by the quality of the fasteners themselves and the operation of the workers. Therefore, when the upper load is too large, the ordinary scaffold support system is difficult to meet the requirements of on-site construction. Content of the Utility Model

[0003] In order to solve the above technical problems, the utility model provides an internal hole support structure of foundation.

[0004] The technical solution of the utility model is realized as follows:

[0005] An internal hole support structure of foundation includes a lattice column support part, a main and secondary beam support part, and a jack part arranged between the top of the lattice column support part and the bottom of the main and secondary beam support part. The lattice column support part is formed by connecting a plurality of lattice columns, and one jack is arranged at the top of each lattice column.

[0006] Further, adjacent two lattice columns are connected by a first angle steel.

[0007] Further, the first angle steel forms multiple groups of connection units between adjacent two lattice columns. Each connection unit includes four angle steels. Among them, two angle steels are cross-distributed to form a cross structure, and the other two angle steels are arranged in parallel up and down at the upper and lower ends of the cross structure.

[0008] Further, the lattice column includes a main body, a column cap and a column foot. The column cap and the column foot are respectively fixedly arranged at the top end and the bottom end of the main body. The column cap and the column foot both include a plate body part and a gusset plate. The plate body part is fixedly connected to the end of the main body. One end of the gusset plate is fixedly connected to one side surface of the plate body part, and one side of the gusset plate is fixedly connected to the side surface of the main body.

[0009] Further, the length of the end of the gusset plate connected to the plate body part is greater than the length of its opposite end to the plate body part.

[0010] Further, the main body includes four second angle steels corresponding to each main body. The outer side surfaces of adjacent two second angle steels are fixedly connected by a lacing bar, and a plurality of lacing bars are arranged along the length direction of the second angle steel.

[0011] Furthermore, the primary and secondary beams within the primary and secondary beam support part are made of I-shaped steel structures.

[0012] The present utility model has the following beneficial effects:

[0013] By adopting I-shaped steel structures for the primary and secondary beams within the primary and secondary beam part, the primary and secondary beams can effectively distribute the force and provide higher flexural strength.

[0014] The lattice columns are connected to each other to form a stable whole, with stable vertical force and can fully support the upper load.

[0015] The internal hole support structure of the foundation of the present application is more stable and safer compared to the general scaffolding support system.

[0016] For the internal hole support structure of the foundation of the present application, each part can be prefabricated in advance, with simple construction, more operability, and time saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1 to 7 shown, a basic internal hole support structure includes a lattice column support part, a primary and secondary beam support part 1, and a jack part 2 arranged between the top of the lattice column support part and the bottom of the primary and secondary beam support part 1. The lattice column support part is composed of a plurality of lattice columns 3 connected together, and a jack part 2 is provided at the top of each lattice column 3.

[0027] By setting the lattice column 3 part to replace the scaffolding support method in the prior art, the stability is stronger and the safety is higher. Moreover, a jack part 2 is provided at the top of each lattice column 3, which can conveniently adjust the height, levelness and ensure the flat installation of the upper formwork.

[0028] Adjacent two lattice columns 3 are connected by a first angle steel 4. Specifically, the first angle steel 4 forms multiple groups of connection units between adjacent two lattice columns 3. Each connection unit includes four angle steels. Among them, two angle steels are cross-distributed to form a cross structure, and the other two angle steels are arranged in parallel up and down at the upper and lower ends of the cross structure. By setting like this, all the lattice columns 3 are connected to each other to form a stable whole, the vertical force is stable, and it can fully support the upper load, further improving the stability and safety.

[0029] Among them, the lattice column 3 includes a main body, a column cap and a column foot. The column cap and the column foot are respectively fixedly arranged at the top end and the bottom end of the main body. The column cap and the column foot both include a plate body part 3.1 and a gusset plate 3.2. The plate body part 3.1 is fixedly connected to the end of the main body, one end of the gusset plate 3.2 is fixedly connected to one side surface of the plate body part 3.1, and one side of the gusset plate 3.2 is fixedly connected to the side surface of the main body. The plate body part 3.1 and the gusset plate 3.2 are both steel plates. By setting like this, the overall rigidity of the lattice column 3 is relatively strong, and the stability between the column cap, the column foot and the main body is relatively strong, and the support effect is good.

[0030] The length of the end of the gusset plate 3.2 connected to the plate body part 3.1 is greater than the length of its opposite end to the plate body part 3.1. By setting like this, the gusset plate 3.2 can more effectively connect the plate body part to the main body, and has relatively strong stability and support effect.

[0031] The main body includes four second angle steels 3.3 corresponding to each main body. The outer side surfaces between adjacent two second angle steels 3.3 are fixedly connected by a lacing bar 3.4, and a plurality of lacing bars 3.4 are arranged along the length direction of the second angle steels 3.3. The lacing bar 3.4 uses a steel plate, and all welds are full welds.

[0032] The primary and secondary beams in the primary and secondary beam support part 1 are of I-shaped steel structure. By setting like this, the primary and secondary beams can effectively distribute the force and provide higher flexural strength.

[0033] Among them, U-shaped hanging rings are pre-buried at corresponding positions at the top of the holes. By using the U-shaped hanging rings, during the later demolition, a chain block is used in cooperation with a crane to demolish the support structure of the holes inside the foundation.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
