Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a steel structure support frame for reinforcing existing buildings. Background Technique

[0002] Steel structure: A steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and rust removal and anti-rust processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. Welds, bolts or rivets are usually used to connect between the components or parts. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields.

[0003] Existing steel structure frames are usually assembled and installed by combining multiple steel frames, and the number of steel frames is increased or decreased according to the dimensions required on site. When the number of steel frames needs to be increased or decreased during the construction process, the existing combined steel frames need to be disassembled and assembled, which is rather troublesome.

[0004] Therefore, we propose a steel structure support frame for reinforcing existing buildings to facilitate solving the problems raised above. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the accompanying drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1-2 As shown, the present utility model provides a steel structure support frame for the reinforcement of existing buildings, which includes a horizontal frame and vertical frames detachably installed on both sides of the horizontal frame. A connecting angle frame 4 is obliquely arranged between the horizontal frame and the vertical frames. The cross-sections of the horizontal frame, the vertical frames and the connecting angle frame 4 are all C-shaped structures;

[0026] The horizontal frame includes a first horizontal frame 11 and a second horizontal frame 12 slidably installed outside the first horizontal frame 11; the vertical frames include a first vertical frame 21 and a second vertical frame 22 slidably installed outside the first vertical frame 21. The first horizontal frame 11 and the second horizontal frame 12 have the same length; the connecting angle frame 4 includes a first angle frame 41 and a second angle frame 42 slidably installed outside the first angle frame 41;

[0027] A plurality of positioning jacks 5 are provided on the side walls of the first horizontal frame 11, the second horizontal frame 12, the first vertical frame 21, the second vertical frame 22, the first angle frame 41 and the second angle frame 42 along their lengths, and positioning pins 6 are inserted into the positioning jacks 5.

[0028] During use, the size of the support frame can be adjusted by inserting the positioning pin 6 into the corresponding positioning jack 5 according to the size required for the reinforcement of the building. Compared with the traditional method of increasing or decreasing the number of steel frames, the adjustment range is wider and it is more convenient to use.

[0029] As a preferred technical solution of the present utility model: a base 3 is provided at the bottom of the first vertical frame 21. The bottom of the first vertical frame 21 and the base 3 are hinged by a pin rod 7. Positioning jacks 5 are provided on the side wall of the base 3. The positioning jacks 5 on the base 3 are located directly above the pin rod 7, and anti-slip tooth patterns 9 are provided at the bottom of the base 3. The setting of the base 3 and the telescopically adjustable connecting angle frame enable the angle between the vertical frame and the horizontal frame to be adjusted. That is, the two first vertical frames 21 can be moved towards the middle of the horizontal frame while ensuring the support range remains unchanged to form a trapezoidal structure to enhance the support stability; at the same time, the positioning jacks 5 directly above the pin rod 7 can ensure that the angle does not change by inserting positioning pins 6 when the vertical rod is vertical. The setting of the anti-slip tooth patterns 9 can enhance the grip and further improve the stability.

[0030] As a preferred technical solution of the present utility model: both the top end of the first vertical frame 21 and the bottom end of the second vertical frame 22 are arc-shaped structures to ensure that they will not be obstructed by edges and corners during angle transformation.

[0031] As a preferred technical solution of the present utility model: a pull ring 8 is provided at one end of the positioning pin 6 to facilitate the staff to insert and remove the positioning pin 6.

[0032] For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances; for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
