Therefore, good stability is shown after welding.

Description

Technical Field

[0001] The utility model relates to the technical field of steel bar truss floor decking, in particular to a steel bar truss self-supporting floor decking. Background Art

[0002] Rebar truss floor decking, also known as truss floor decking, is a prefabricated building formwork, mainly used to support floors and bear loads. Rebar truss floor decking is a composite structural system formed by processing the main load-bearing steel bars in the floor slab into steel trusses using special equipment in the factory, and then welding the steel trusses with galvanized steel plates into one. This floor decking uses steel bars as the upper chord, lower chord and web members, which are connected by resistance spot welding to form a truss, and then connected to the bottom plate (such as galvanized steel plate) by resistance spot welding to form an integral combined load-bearing plate.

[0003] The existing steel truss floor deck is generally welded with upper chord steel bars and web steel bars and lower chord steel bars at the upper end of the bottom form to ensure its strength. However, the upper chord steel bars and web steel bars and lower chord steel bars welded at the upper end of the bottom form are not convenient to fully strengthen the ends, center, bottom and sides to enhance its service strength. For this reason, we propose a steel truss self-supporting floor deck. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] To this end, the technical solution adopted in this utility model is:

[0007] Preferably, a middle clip is provided at the center of the upper portion of the side support seat and the upper portion of the middle support seat, and the middle clip matches the upper chord steel bar.

[0008] Preferably, side clips are provided on both sides of the upper portion of the side support seat and the upper portion of the middle support seat, and the side clips match the web reinforcement bars.

[0024] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0025] The following describes the self-supporting floor decking of steel trusses provided by some embodiments of the present invention in conjunction with the accompanying drawings.

[0026] Example 1:

[0027] Combine Figure 1-5 As shown, the steel truss self-supporting floor deck provided by the present invention includes: a steel truss body 100, a reinforcement assembly 200; the steel truss body 100 includes a bottom form 101 at its bottom, an upper chord steel bar 102 at the upper end of the bottom form 101, web steel bars 103 on both sides of the upper chord steel bar 102, and a lower chord steel bar 104 outside the web steel bar 103; the reinforcement assembly 200 includes side support seats 201 welded and fixedly installed on both sides of the bottom form 101, a bottom reinforcement plate 202 welded and fixedly installed between the side support seats 201, a middle support seat 203 welded and fixedly installed at the upper end of the bottom reinforcement plate 202, and positioning holes opened on both sides of the side support seats 201. The socket 204 and the reinforcement rod 205 movably installed in the positioning socket 204, the upper part of the side support seat 201 and the center of the upper part of the middle support seat 203 are both provided with a middle clip 206, and the middle clip 206 matches the upper chord steel bar 102, the upper part of the side support seat 201 and the upper part of the middle support seat 203 are both provided with side clips 207, and the side clips 207 match the web steel bar 103, and the lower part of the side support seat 201 is also provided with lower clips 208 on both sides, and the lower clips 208 match the lower chord steel bar 104, and the lower end of the side support seat 201 is also provided with weld feet 209. The reinforcement rod 205 is a U-shaped structure.

[0028] Specifically, the steel truss floor deck is an assembled building formwork, mainly used for supporting floors and bearing loads; the side support seats 201 and the middle support seat 203 installed at both ends and the center of the upper chord steel bars 102, the web steel bars 103, and the lower chord steel bars 104 at the upper end of the bottom form 101 in this steel truss body 100 can significantly enhance the supporting strength and impact resistance of the steel truss at the upper end of the bottom form 101 after welding, thereby ensuring its overall strength and avoiding deformation during pouring or construction when pouring cement at the upper end of the steel truss body 100. At the same time, the middle clip 206, the side clip 207 and the lower clip 208 opened at the upper ends of the side support seat 201 and the middle support seat 203 can also ensure the matching and engagement between the upper chord steel bars 102, the web steel bars 103, and the lower chord steel bars 104 at the upper end of the bottom form 101. Thus, it shows good stability after welding, and the reinforcing rods 205 that are welded and fixed to the web reinforcement bars 103 on both sides after installation at both ends of the side support seats 201 can also clamp and position the web reinforcement bars 103 on both sides and ensure their supporting strength after installation, thereby reducing their deformation and misalignment problems, to ensure that the web reinforcement bars 103 on both sides are evenly stressed, and to strengthen the overall strength of the steel truss body 100. The bottom reinforcement plate 202 connected between the side support seats 201 at both ends and the middle support seat 203 mainly connects the side support seat 201 and multiple groups of middle support seats 203 into a whole, thereby forming a more stable structure. The welding feet 209 at both ends of the side support seat 201 are mainly used for welding and fixing the two ends of the side support seat 201 to the upper end of the bottom mold 101 to ensure the stability of the side support seat 201.

[0029] The working principle and use process of this utility model:

[0030] During the casting and construction of the upper end of the steel truss body 100, the lower parts of the upper chord steel bars 102, the web steel bars 103 and the lower chord steel bars 104 are located at the side support seats 201 and the middle support seats 203 arranged at both ends and the center, and are connected to form an integral structure by the bottom reinforcement plate 202 to provide stable and uniform support for the ends and the middle of the upper chord steel bars 102, the web steel bars 103 and the lower chord steel bars 104, so as to ensure the strength and anti-deformation of the steel frame composed of the upper chord steel bars 102, the web steel bars 103 and the lower chord steel bars 104. At the same time, the reinforcing rods 205 inserted at both ends of the side support seat 201 can also be clamped on the outer ends of the web reinforcement bars 103 on both sides, so as to position the web reinforcement bars 103 in an inclined position to avoid deformation of the web reinforcement bars 103 during construction and ensure that the force is evenly distributed. In this way, the upper chord reinforcement bars 102, the web reinforcement bars 103 and the lower chord reinforcement bars 104 are evenly and reasonably supported and restrained at both ends, the middle, the bottom and the sides of the steel frame, so as to significantly enhance the overall strength of the steel truss body 100.
