The section steel is connected by high-strength bolts, the end plates are welded at two ends of the section steel, and the rib plates are welded between two flange plates of the section steel. The device can be used for reinforcing and connecting the steel triangular piece and the steel purlin of the foundation pit angle brace support. Compared with the prior art, the utility model has the advantages of simple installation, convenient transportation, environmental protection, obvious reinforcing effect on the diagonal brace support and the steel purlin, shortened support net distance and the like.
Description
Technical Field
The utility model relates to a reinforcing triangular member, which is mainly applied to foundation pit assembled type steel supports in civil and industrial infrastructure construction.
Background
At present, various foundation pits begin to widely use steel supports as support forms, and in the foundation pit supported by fully-assembled type steel, a steel triangular component is commonly used in an area adopting an angle support to be connected with a steel purlin or a fender post so as to meet the requirements of the support integrity and the foundation pit stability. In the position with larger soil reaction force, in order to meet the requirements of integral stability and material rigidity, the conventional method is to shorten the supporting distance or adopt double-spliced or multi-spliced steel enclosing purlins, but the steel consumption is greatly increased, and the labor and construction cost are increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims to reduce the supporting net distance on the premise of ensuring the safety of a foundation pit, strengthen the connection between the steel triangular component and the steel purlin and reduce the steel consumption and the construction cost.
A device capable of reinforcing a triangular steel component of a foundation pit angle brace comprises section steel, rib plates, end plates and high-strength bolt assemblies. The section steel is connected by high-strength bolts, the end plates are welded at two ends of the section steel, and the rib plates are welded between two flange plates of the section steel.
The device capable of reinforcing the triangular steel component of the foundation pit angle brace is characterized in that bolt holes are formed in two flange plates of profile steel and correspond to bolt holes of the angle brace support and the steel surrounding purlin one by one.
The device capable of reinforcing the steel triangular component of the foundation pit angle brace is characterized in that the welding position of the rib plates between the profile steel flange plates corresponds to the positions of the steel triangular component and the reinforcing ribs of the steel surrounding purlin.
The device capable of reinforcing the triangular steel component of the foundation pit angle brace is characterized in that the device finally forms an A-shaped base component (1), a B-shaped base component (2), a C-shaped base component (3), a D-shaped base component (4) and an E-shaped base component (5) through section steel, rib plates and end plates and through assembly.
A device capable of reinforcing a steel triangular component of a foundation pit corner brace is characterized by comprising the following steps:
(1) setting out a real model according to the construction drawing;
(2) assembling, namely installing a purlin and an assembling device according to the requirements of a drawing;
(3) the device is in place, and the steel triangular member reinforcing device is moved to a position to be constructed;
(4) connecting the triangular member reinforcing device with the steel triangular member and the steel purlin by using high-strength bolts;
(5) and supporting and pressurizing, and secondarily fastening all the bolts.
Compared with the prior art, the method has the following characteristics:
1. increase the connecting area of the angle brace support and the steel purlin.
Through supplementary the enhancement of diagonal brace steel triangle component, can the support whole with enclose purlin area of being connected to reduce and support the net interval with adjacent, when can make full use of support strength, increase the steel and enclose purlin intensity utilization ratio.
2. The bending moment that original triangle component can bear is increased.
When the soil reaction force is larger, the deformation of the triangular member support can be reduced by reinforcing the triangular member support.

The device is used in the assembled profile steel angle brace of the foundation pit.
The method specifically comprises the following steps:
(1) setting out a real model according to the construction drawing;
(2) assembling, namely installing a purlin and an assembling device according to the requirements of a drawing;
(3) the device is in place, and the steel triangular member reinforcing device is moved to a position to be constructed;
(4) connecting the device with a steel triangular member and a steel purlin by using high-strength bolts;
(5) and applying prestress to the support, and secondarily fastening all the bolts.
Claims (5)
