Description

Technical Field

[0001] The utility model relates to a steel structure construction technology, in particular to an I-beam construction technology, and specifically is a cantilever floor decking rapid supporting device. Background Art

[0002] With the continuous rise of steel structures in the construction industry, supporting steel structure floor decking has also been widely used. Compared with traditional formwork and steel bar binding, steel truss floor decking has reduced the number of processes and adopted mechanized production, which greatly improved the construction efficiency and ensured safe and civilized construction.

[0003] Cantilevered steel decking is a type of decking that is commonly encountered in floor decking. The following three support methods are often used to ensure the safety and reliability of the cantilevered decking: 1. Adding angle steel supports; 2. Adding edge-sealed steel beams to support the steel truss floor decking; 3. Adding supporting corbels on the inner steel beams. The first form allows for on-site welding of angle steel supports, which increases materials and labor. The second and third methods require the structure itself to meet the conditions for adding corresponding steel beams and corbels, and the cost increase is relatively large. The above three methods are more troublesome if they involve an impact on the appearance. The first method requires secondary cutting, grinding, and painting, and the second and third methods are basically impossible to remove, which will affect the appearance to a certain extent. Summary of the invention

[0004] The purpose of the utility model is to overcome the above-mentioned defects and to provide a fast, safe and efficient method for supporting cantilevered steel truss floor decks, which can be quickly adjusted and rearranged as needed to facilitate on-site construction.

[0005] In order to achieve the above object, the utility model is achieved as follows:

[0006] A cantilever floor deck quick support device comprises a vertical support (1), a tie rod (2), and an inclined support (3), wherein the vertical support (1) is vertically arranged between the upper and lower flanges of a steel beam, the bottom of the inclined support (3) is connected to the bottom of the vertical support (1), the top of the inclined support (3) extends in a direction away from the upper flange of the steel beam, and the top of the inclined support (3) is connected to the top of the vertical support (1) via the tie rod (2).

[0007] The cantilever floor decking quick support device has a vertical support (1) that is assembled and has an adjustable length. The vertical support (1) comprises a support screw (1.1), a support sleeve (1.2) and a first adjusting nut (1.3). The support screw (1.1) is inserted into the support sleeve (1.2) and the first adjusting nut (1.3) is used to form the vertical support (1). The fastening height can be adjusted and the vertical support (1) is tightly fixed to the upper and lower flanges of the steel beam.

[0008] The cantilever floor decking quick support device described above has a pull rod (2) that is assembled and has an adjustable length, and includes a first pull rod hoop (2.1), a pull rod flange (2.2), a second pull rod hoop (2.4) and a first hinge bolt (2.3); the first pull rod hoop (2.1) is rigidly connected to the pull rod flange (2.2), and the pull rod flange (2.2) and the second pull rod hoop (2.4) are hingedly connected via the first hinge bolt (2.3), and together they form a pull rod (2) for adjusting the support position laterally and fixing the relative relationship between the vertical support (1) and the diagonal support (3).

[0009] The cantilever floor decking rapid support device has an assembled diagonal brace (3) with adjustable length, comprising a supporting angle steel (3.1), a diagonal brace sleeve (3.2), a diagonal brace screw (3.3), a second adjustment nut (3.4), and a second hinge bolt (3.5); the supporting angle steel (3.1) and the diagonal brace sleeve (3.2) are rigidly connected, the diagonal brace screw (3.3) is inserted into the diagonal brace sleeve (3.2), and the matching second adjustment nut (3.4) is used to achieve a telescopic effect, and together they form a diagonal brace (3); the diagonal brace (3) is hingedly connected to the vertical support (1) through the second hinge bolt (3.5), constraining the diagonal brace (3) and ensuring that the diagonal brace (3) can adapt to different angle adjustments.

[0010] This device uses support screws and support sleeves to assemble a vertical support device with adjustable fastening length, making the cantilever truss support installation more flexible and fast, greatly improving the work efficiency. Compared with the existing technology, it has the following characteristics:

[0011] 1. Simple structure, easy to process and manufacture.

[0012] 2. Higher flexibility: It can be quickly adjusted and reconfigured as needed.

[0013] 3. It can be prepared in batches, with simple on-site installation and easy operation, which improves the efficiency of temporary support construction of floor decking. After the concrete of the floor decking is poured in the later stage, it can be dismantled for the support construction of the next floor decking, which improves turnover and reduces the cost of engineering construction, and is conducive to the construction of standardized and civilized construction sites.
