Description

Technical Field

[0001] The utility model belongs to the technical field of assembled buildings, and in particular relates to a steel bar truss floor deck connecting piece. Background Art

[0002] The steel truss floor deck is a building product in which the load-bearing steel bars in the floor slab are welded into steel trusses in the factory, and the steel trusses are fixedly connected to the bottom formwork to form an integrated bottom formwork and the load-bearing steel bars. During construction, the steel truss floor deck is fixed between two load-bearing beams and concrete is directly poured. The bottom formwork bears the gravity of the concrete, and the steel trusses provide unsupported stiffness for the bottom formwork. Compared with traditional floor decks that support concrete through the bottom formwork, the steel truss floor deck speeds up the construction progress and enhances the supporting effect.

[0003] According to the patent disclosed in announcement number CN213683190U, a steel truss floor deck bottom formwork connector is disclosed. A steel truss floor deck bottom formwork connector is disclosed. The base plate is bent downward to form a first folded plate, the first folded plate is bent in the opposite direction of the base plate to form a second folded plate, the second folded plate is bent downward to form a third folded plate, the first folded plate, the second folded plate and the first steel truss floor deck bottom formwork form a cavity, the second connector includes a fixed plate and an extension plate, the fixed plate is fixedly installed below the edge of the second steel truss floor deck bottom formwork, the extension plate is located outside the edge of the second steel truss floor deck bottom formwork, and the extension plate is clamped in the cavity.

[0004] While the above technical solution offers a simple structure and low processing costs, it also makes the connection between the steel truss floor decking bottom formwork tighter and facilitates disassembly. However, this solution has certain shortcomings in actual use. After the first and second connectors are spliced ​​together, there is no restraining structure to keep them tightly together. This results in the bayonet joints of the two adjacent steel truss floor decking bottom formworks not fitting tightly together, resulting in an excessively large gap between the two steel truss floor decks. This still presents the risk of concrete leaking through the gap during use. To address this issue, we provide a steel truss floor decking connector to address the above issues.

The first fixing bolt 6 is screwed into the first connector 3 and the first base form 1 by using a tool, and the first base form 1 and the first connector 3 can be fixedly installed at this time. A second base form 2 is provided on the right side of the first base form 1, and the internal thread of the second connector 4 is connected to a second fixing bolt 7, and the second fixing bolt 7 is screwed to the second base form 2. The second fixing bolt 7 is screwed into the second connector 4 and the second base form 2 by using a tool, and the second base form 2 and the second connector 4 can be fixedly installed at this time.

[0026] See also Figure 2 and Figure 3 As shown, a first connecting member 3 is provided on the top of the first bottom mold 1. The first connecting member 3 includes a first fixing plate 301. A first threaded groove 302 is defined within the first fixing plate 301, and the first threaded groove 302 is threadedly engaged with the first fixing bolt 6. A retaining groove 303 is defined within the first fixing plate 301, and a second threaded groove 304 is defined within the first fixing plate 301. A second fixing plate 401 is inserted into the retaining groove 303, which can limit the position of the second fixing plate 401, thereby improving the connection between the first connecting member 3 and the second connecting member 4.

[0027] See also Figure 4 As shown, the top of the second base mold 2 is provided with a second connecting member 4, which includes a second fixing plate 401. A third threaded groove 402 is defined within the second fixing plate 401, and the third threaded groove 402 is threadedly engaged with the second fixing bolt 7. A slot 403 is defined within the second fixing plate 401, and a rod 506 is fixedly connected to the outer surface of a limit block 504, which is inserted into the slot 403. Both the slot 403 and the rod 506 are designed in pairs. When the rod 506 is inserted into the slot 403, it can achieve a fixed and limiting effect between the first connecting member 3 and the second connecting member 4.

[0028] See also Figure 4 、 Figure 5 and Figure 6 As shown, the outer surface of the adjusting screw 501 is rotatably connected to the limit block 504, and the inner portion of the second fixing plate 401 defines a limit slot 404. Both the limit slot 404 and the limit block 504 are designed to be elliptical. The limit slot 404 is slightly larger than the limit block 504, allowing the limit block 504 to smoothly pass through the limit slot 404 to the right side.

[0029] See also Figure 5 and Figure 6As shown, a fastening mechanism 5 is provided inside the first connecting member 3. The fastening mechanism 5 includes an adjusting screw 501, which is threadedly connected to the second thread groove 304. A knob 502 is fixedly connected to one end of the adjusting screw 501, and a circular plate 503 is fixedly connected to the other end of the adjusting screw 501. A movable groove 505 is provided inside the limit block 504, and the inner wall of the movable groove 505 rotates with the outer surface of the circular plate 503. By rotating the knob 502, the adjusting screw 501 can be driven to rotate, and then the adjusting screw 501 drives the circular plate 503 to rotate accordingly. At the same time, the adjusting screw 501 drives the circular plate 503 to move laterally, which in turn drives the limit block 504 and the movable groove 505 to move laterally, thereby achieving the effect of adjusting the lateral position of the limit block 504 and the movable groove 505.

[0030] The working principle and usage method of the utility model are as follows: when the utility model is in use, the first fixing bolt 6 is screwed into the first connecting member 3 and the first bottom mold 1 by using a tool, and the first bottom mold 1 and the first connecting member 3 can be fixedly installed. Then the second connecting member 4 is inserted into the slot 303, and the limit block 504 passes through the limit slot 404 and to its right side. Then the second fixing bolt 7 is screwed into the second connecting member 4 and the second bottom mold 2 by using the same tool. At this time, the second bottom mold 2 and the second connecting member 4 can be fixedly installed. Then the limit block 504 is rotated ninety degrees. At this time, the limit block 504 is vertical to the limit slot 404, and the two are limited to each other. At this time, it is necessary to use a tool or one hand to keep the rotated limit block 504 in a stationary state, and then by turning the knob 502, the adjusting screw 501 can be driven to rotate. , then the adjusting screw 501 will drive the circular plate 503 to rotate, and at the same time, the adjusting screw 501 will drive the circular plate 503 to move to the left, and then the circular plate 503 will drive the limit block 504 and the movable slot 505 to move to the left. At this time, the insertion rod 506 will be driven to insert into the slot 403, thereby limiting and fixing the second fixed plate 401 and the first fixed plate 301. When the limit block 504 continues to move to the left, it will drive the second fixed plate 401 to move close to the first fixed plate 301, thereby reducing the distance between the first connecting member 3 and the second connecting member 4, so that the first connecting member 3 and the second connecting member 4 can fit closely together, thereby making the first bottom mold 1 and the second bottom mold 2 fit closely together, thereby reducing the gap between the first bottom mold 1 and the second bottom mold 2, thereby effectively preventing concrete from leaking from the gap between the first bottom mold 1 and the second bottom mold 2.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
