Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar truss floor deck structure design, and in particular relates to a steel bar truss floor deck buckle assembly. Background Art

[0002] In modern construction projects, steel truss floor decking is a common form of floor structure and is widely used due to its excellent mechanical properties and construction convenience. The steel truss floor decking consists of two parts: the steel truss and the floor decking. The steel truss plays the main load-bearing role, while the floor decking serves as the formwork during the construction process and the permanent bottom formwork of the floor slab. In order to ensure a firm connection between the floor decking and the steel truss, special clip components are required for fixing.

[0003] According to the patent announcement number CN220908898U, a clip-on steel truss floor deck is disclosed, which includes a base plate, a plurality of slots are provided on the left and right sides of the upper surface of the base plate, a clip is provided inside the two corresponding slots, a positioning block is provided inside the clip on the upper surface of the base plate, a plurality of cavities are provided on the upper surface of the base plate, a locking device is provided inside the plurality of cavities, and the locking device includes a bidirectional threaded sleeve.

[0004] The above technical solution facilitates the installation and disassembly of steel trusses and, to a certain extent, meets the needs of fixing steel trusses. However, it has obvious limitations. Because there is only one socket inside the clamp, the distance between the clamp and the positioning block is relatively fixed. This means that the clamp can only fix lower chord steel bars of a specific size. If the clamp can only fix steel bars of a specific size, then in actual application, it is necessary to prepare multiple clip assemblies of different specifications, which not only increases construction costs but also may cause confusion on the construction site and reduce construction efficiency. To this end, we provide a steel truss floor deck clip assembly to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and provide a steel bar truss floor deck buckle assembly.

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] See also Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a steel truss floor deck clip assembly, specifically comprising a base plate 1 having a movable groove 2 defined therein. The movable groove 2 is capable of retaining an elastic member 504, preventing the elastic member 504 from twisting and disengaging, thereby affecting its elasticity. A chute 3 is defined therein, and a rod 503 is fixedly connected to the outer surface of a limiting plate 502. The outer surface of the rod 503 slides against the inner wall of the chute 3. A slot 2 8 is defined within the clip 6. The chute 3 guides the rod 503, ensuring that the rod 503 can be directly inserted into the interior of the slot 2 8 to retain the clip 6. A slot 1 4 is defined within the base plate 1. The lower chord steel bar to be secured is placed on the base plate 1. At the same time, the handle 501 is pulled to move the limiting plate 502 and the rod 503 away from the clip 6. The clip 6 is then inserted into the slot 1 4 to achieve a preliminary retaining effect on the clip 6. A limiting mechanism 5 is provided inside the movable groove 2. By providing the limiting mechanism 5, the position of the fastener 6 can be quickly fixed, and the lower chord steel bar inside the fastener 6 can be limited.

[0024] See also Figure 3 and Figure 4As shown, the limiting mechanism 5 specifically includes a handle 501. The outer surface of the handle 501 slides with the inner wall of the movable groove 2. A socket is provided inside the handle 501 to facilitate the operator to insert his fingers to pull the handle 501 to move, making the operation more labor-saving. The outer surface of the handle 501 is fixedly connected to the limiting plate 502. The outer surface of the limiting plate 502 slides with the inner wall of the movable groove 2. The insertion rod 503 is inserted into the interior of the slot 2 8. The outer surface of the limiting plate 502 is fixedly connected to an elastic member 504. The end of the elastic member 504 away from the limiting plate 502 is fixedly connected to the inner wall of the movable groove 2. The elastic member 504 is made of a spring and has elastic and retractable rebound properties, which can achieve a rapid reset and movement effect of an object.

[0025] Specifically in this embodiment, by pulling the handle 501, the limit plate 502 and the insertion rod 503 can be driven to move along, and at this time, the limit plate 502 will be driven to squeeze the elastic member 504. At the same time, the elastic member 504 will be elastically deformed under the force and store a certain potential energy. When the handle 501 is released, the deformed elastic member 504 will release the elastic potential energy, and then push the limit plate 502 to move in the opposite direction. Then the limit plate 502 will drive the handle 501 and the insertion rod 503 to move along, thereby achieving a rapid reset effect of the handle 501, the limit plate 502 and the insertion rod 503.

[0026] See also Figure 3 and Figure 5 As shown, a clip 6 is inserted into slot 1 4, and a limiting groove 7 is defined within the clip 6. A fixing block 902 is rotatably connected to the outer surface of the adjusting screw 901. The outer surface of the fixing block 902 slides against the inner wall of the limiting groove 7. The limiting groove 7 can limit the fixing block 902, thereby enabling the fixing block 902 to move horizontally and longitudinally to compress and secure the rebar. A compression structure 9 is provided within the clip 6. By providing the compression structure 9, the lower chord rebar placed inside the clip 6 can be compressed and secured, and can accommodate a variety of rebar sizes.

[0027] See also Figure 3 and Figure 5 As shown, the compression structure 9 includes an adjusting screw 901, which is threadedly connected to the snap member 6. One end of the adjusting screw 901 is fixedly connected to a push plate 903. The outer surface of the push plate 903 rotates with the inner wall of the fixed block 902. The other end of the adjusting screw 901 is fixedly connected to a knob 904. Turning the knob 904 drives the adjusting screw 901 and the push plate 903 to rotate accordingly, so that the adjusting screw 901 drives the push plate 903 to move downward, and then the push plate 903 drives the fixed block 902 to move downward. At this time, the fixed block 902 will press down and fix the lower chord steel bar below. It can adapt to a variety of steel bars of different sizes, which not only reduces construction costs but also helps to improve order and construction efficiency on the construction site.

[0028] The specific working principle of the present invention is as follows: when in use, the lower chord steel bar that needs to be fixed can be placed on the bottom plate 1, and the handle 501 needs to be pulled to drive the limit plate 502 and the insertion rod 503 to move away from the clip 6, and then the clip 6 is inserted into the slot 4. At this time, the lower chord steel bar is located on the inner side of the clip 6, and then the handle 501 is released. At this time, the deformed elastic member 504 will release its elastic potential energy, and then push the limit plate 502, the handle 501 and the insertion rod 503 to move close to the clip 6, so that the insertion rod 503 can be inserted into the slot 4. The rod 503 is inserted into the slide groove 3 and the slot 2 8, and then the fixed limit of the fastener 6 can be achieved. Then, the knob 904 is turned to drive the adjusting screw 901 and the push plate 903 to rotate accordingly, so that the adjusting screw 901 drives the push plate 903 to move downward, and then the push plate 903 will drive the fixing block 902 to move downward. At this time, the fixing block 902 will press the lower chord steel bar downward and fix it. It can adapt to a variety of steel bars of different sizes, which not only reduces construction costs, but also helps to improve the order and construction efficiency of the construction site.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
