Description

Technical Field

[0001] This utility model relates to the field of steel structure construction technology, and in particular to a sliding rail type liftable irregular steel structure assembly frame. Background Technology

[0002] During steel structure construction, especially for stadiums, steel structures are complex and diverse in shape, often featuring irregular spatial forms and large component cross-sections. These components cannot be fabricated as whole pieces in the factory and transported to the site, necessitating on-site assembly. Currently, steel structure assembly jigs are mostly fabricated temporarily on-site using materials such as H-beams and steel pipes. On-site fabrication of these jigs is characterized by diverse forms, lack of standardized design, significant material waste during cutting, environmental unfriendliness, and substantial safety (load-bearing capacity) challenges due to on-site welding. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the existing technology and provide a sliding rail type liftable irregular steel structure assembly frame, which can be assembled and adjusted according to the weight and shape of the irregular steel structure, with high flexibility and improved construction efficiency.

[0004] To achieve the above technical effects, this utility model provides a sliding rail type liftable irregular steel structure assembly frame, comprising multiple unit frames that are detachably connected to each other, characterized in that each unit frame includes:

[0005] Two slide rails;

[0006] Two sets of columns, which are designed to support irregular steel structures and are height-adjustable, are slidably installed on two slide rails. Each set of columns includes multiple column bodies spaced apart along the length of the slide rail.

[0007] A telescopic assembly for adjusting the distance between two adjacent column bodies on each of the slide rails is telescopically connected between two adjacent column bodies along the length direction of the slide rail.

[0008] Preferably, each of the column bodies is equipped with a sliding trolley at its bottom for sliding along the slide rail.

[0009] Preferably, each column body includes a first square tube arranged vertically, a second square tube movably inserted into the first square tube, and a pin for inserting into the first square tube and the second square tube to fix them relative to each other.

[0010] Preferably, the two sets of columns are telescopically connected by a horizontal brace, and the horizontal brace is obliquely connected to the adjacent column body by a diagonal brace.

[0011] Preferably, the telescopic assembly includes two third-party tubes connected between two adjacent column bodies along the length direction of the slide rail, the two third-party tubes being arranged in a cross shape and a pin being inserted and connected at the intersection.

[0012] The technical effects achieved by this utility model due to the adoption of the above technical solution are as follows:

[0013] 1) By setting an expansion joint between two adjacent column bodies along the length of the slide rail, the length of the assembly jig can be adjusted, thus making it suitable for assembling steel trusses of different lengths.

[0014] 2) By setting up horizontal and diagonal braces, the rigidity and stability of each unit frame can be ensured.

[0015] 3) By setting a slide rail, the bottom of the column body is equipped with a sliding trolley that can move on the slide rail, which can adjust the distance between two adjacent column bodies. The column body is composed of nested first square tubes and second square tubes of different sizes, which can adjust the height of each column body to adapt to steel structures of different sizes.

[0016] 4) It can be processed and manufactured in the factory and then transported to the construction site for assembly according to the different sizes of irregular steel structures. It is highly flexible, practical, and fast in assembly, thus improving construction efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 As shown, this utility model embodiment provides a sliding rail type liftable irregular steel structure assembly frame, including multiple unit frames that are detachably connected to each other. Adjacent unit frames are connected by pins for easy disassembly. Each unit frame includes two sliding rails 6, two sets of columns, and a telescopic component 5. Two sets of columns, adjustable in height and designed to support the irregular steel structure 1, are slidably mounted on the two sliding rails 6. Each set of columns includes multiple column bodies 2 spaced apart along the length of the sliding rail 6. The telescopic component 5 is used to adjust the spacing between two adjacent column bodies 2 on each sliding rail 6, and is telescopically connected between adjacent column bodies 2 along the length of the sliding rail 6. It should be noted that in this embodiment, the sliding rails 6 are made of I-beams or angle steel, allowing the spacing between the two sliding rails 6 to be adjusted according to the dimensions of the irregular steel structure, thereby avoiding conflict with the columns and trusses of the irregular steel structure.

[0023] Furthermore, each column body 2 is equipped with a sliding trolley 7 at its bottom for sliding on the slide rail 6. The sliding trolley 7 adopts a conventional combination of sliding shoe and wheel, and is equipped with a self-locking component, allowing it to roll on the slide rail 6. Preferably, each column body 2 includes a first square tube 21 arranged vertically, a second square tube 22 movably inserted into the first square tube 21, and a pin for inserting into the first square tube 21 and the second square tube 22 to fix them relative to each other. By using first square tubes 21 and second square tubes 22 of different sizes nested together, the height of the column body 2 can be adjusted according to the height of the irregular steel structure truss, and fixed by the pin.

[0024] Furthermore, a horizontal brace 3 is telescopically connected between the two sets of columns, and a diagonal brace 4 is obliquely connected between the horizontal brace 3 and the adjacent column body 2. The horizontal brace 3 is composed of nested rectangular tubes of the same size as the column body 2 and is fixed by pins. It can be used to adjust the width of the unit frame, thus making it suitable for assembling trusses of different widths. It should be noted that an intermediate column can be set at the connection of the two rectangular tubes of the horizontal brace 3. A sliding trolley is set at the bottom of the intermediate column and a third slide rail is provided for the sliding trolley to slide on, thereby ensuring the rigidity and stability of each unit frame. Preferably, in this embodiment, the telescopic component 5 includes two third-party tubes 51 connected between two adjacent column bodies 2 along the length direction of the slide rail 6. The two third-party tubes 51 are arranged in a cross shape, and a pin is inserted at the intersection. The telescopic component 5 can be set as one or more according to the length of the assembly frame. When multiple telescopic components are set, adjacent telescopic components 5 are connected by pins, and a sliding trolley can also be set at the bottom of the connection for sliding on the slide rail 6.
