Description

Technical Field

[0001] This utility model relates to the field of steel truss technology, and in particular to a steel truss thin-walled plate that eliminates the need to measure the bottom formwork height. Background Technology

[0002] Reinforced truss thin-walled panels are a type of unsupported profiled composite thin-walled panels. A truss is formed by connecting steel bars as top chords, bottom chords, and web bars through resistance spot welding. The lower end of the steel truss and the steel mesh are then poured with concrete to form the reinforced truss thin-walled panel.

[0003] During the concrete pouring process, in order to ensure the quality of the pouring, the height of the concrete is measured multiple times. If the concrete height is insufficient, multiple pours are required to ensure that the pouring height is within the set range, which wastes time and reduces the efficiency of the pouring operation. Utility Model Content

[0004] This application provides a steel truss thin-walled slab with a bottom formwork height that eliminates the need for measurement. This solves the problem in the prior art where, in order to ensure the quality of the pouring, the height of the concrete is measured multiple times. If the concrete height is insufficient, multiple pours are required to ensure that the pouring height is within the set range, which wastes time and results in insufficient pouring efficiency.

[0005] This application provides a steel truss thin-walled slab with no need to measure the bottom formwork height, including a steel truss body, a bottom formwork, and transverse steel bars. The steel truss body includes multiple web bars and multiple bottom chord bars. Two web bars form a group, and the two web bars in the same group are arranged in a mirror image. The web bars and bottom chord bars are welded together. The bottom end of the web bars is welded to the transverse steel bars, and multiple longitudinal steel bars are welded to the upper surface of the transverse steel bars.

[0006] The top two sides of the two outermost longitudinal steel bars are welded with positioning triangle plates, and the bottom two sides of the two outermost lower chord bars are provided with positioning triangle grooves that match the positioning triangle plates. The positioning triangle plates are movably disposed in the positioning triangle grooves.

[0007] The multiple lower chords are parallel, and several standard plates are welded to the bottom ends of the multiple lower chords. The top surface of the bottom template is flush with the bottom surface of the standard plates.

[0008] Preferably, the steel truss body further includes an upper chord bar, and the upper inner ends of the two web bars in each group are welded and fixed to the upper chord bar.

[0009] Preferably, the number of the web reinforcement and the lower chord reinforcement are in one-to-one correspondence.

[0010] Preferably, the standard plate has an L-shaped cross-section.

[0011] Preferably, the transverse and longitudinal reinforcing bars are welded together to form a reinforcing mesh.

[0012] Preferably, each of the web reinforcement bars includes several upper and lower segments, with two adjacent upper segments and the same lower segment integrally formed, the lower segments welded to the transverse reinforcement bars, and the upper segments welded to the lower chord reinforcement bars.

[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0014] By employing a design that incorporates bottom chord reinforcement, longitudinal reinforcement, positioning triangle plates, positioning triangle grooves, and a standard plate, multiple bottom chord reinforcements can be welded to the web reinforcement at a set height through the cooperation of the positioning triangle plates and positioning triangle grooves. The standard plate at the bottom of the bottom chord reinforcement serves as a height gauge for the bottom formwork, facilitating visual observation during concrete pouring and eliminating the need for multiple measurements, thus reducing labor and improving pouring efficiency.

[0028] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] like Figures 1 to 11 As shown, this application provides a steel truss thin-walled slab with no need to measure the bottom formwork height, including a steel truss body 100, a bottom formwork 200 and transverse steel bars 141. The steel truss body 100 is disposed inside the bottom formwork 200. The steel truss body 100 includes multiple web bars 130 and multiple bottom chord bars 120. Two web bars 130 form a group, and the two web bars 130 in the same group are arranged in a mirror image. The web bars 130 and the bottom chord bars 120 are welded. The bottom end of the web bars 130 is welded to the transverse steel bars 141. Multiple longitudinal steel bars 140 are welded to the upper surface of the transverse steel bars 141.

[0031] The top sides of the two outermost longitudinal steel bars 140 are welded with positioning triangle plates 150, and the bottom sides of the two outermost lower chord steel bars 120 are provided with positioning triangle grooves 151 that match the positioning triangle plates 150. The positioning triangle plates 150 are movably disposed in the positioning triangle grooves 151.

[0032] Further explanation: The design of the positioning triangle plate 150 and the positioning triangle groove 151 is to determine the specific location of the lower chord reinforcement 120 on the outer wall of the web reinforcement 130 by cooperating with the positioning triangle plate 150 and the positioning triangle groove 151 during the welding process of the steel truss body 100, after determining the location of the longitudinal reinforcement 140 mesh.

[0033] The multiple lower chord ribs 120 are parallel, and several standard plates 160 are welded to the bottom ends of the multiple lower chord ribs 120. The top surface of the bottom template 200 is flush with the bottom surface of the standard plate 160.

[0034] Further explanation: The design of the standard slab 160 provides a height benchmark for the pouring of the bottom formwork 200. When the concrete pouring height reaches the bottom surface of the standard slab 160, it indicates that the concrete pouring height is the set height and meets the pouring height requirements.

[0035] Specifically, the steel truss body 100 also includes an upper chord bar 110, and the upper inner ends of the two web bars 130 in each group are welded and fixed to the upper chord bar 110.

[0036] Specifically, the number of the web reinforcement 130 and the lower chord reinforcement 120 are in one-to-one correspondence.

[0037] Specifically, the cross-section of the standard plate 160 is L-shaped.

[0038] Specifically, the transverse steel bars 141 and the longitudinal steel bars 140 are welded together to form a steel mesh.

[0039] Further details: The transverse steel bars 141 and the longitudinal steel bars 140 are arranged horizontally in the transverse direction and horizontally in the longitudinal direction, respectively, and the transverse steel bars 141 and the longitudinal steel bars 140 are welded perpendicularly to each other.

[0040] Specifically, each of the web reinforcement bars 130 includes several upper and lower segments. Two adjacent upper segments and the same lower segment are integrally formed. The lower segments are welded to the transverse reinforcement bars 141, and the upper segments are welded to the lower chord reinforcement bars 120.

[0041] Further details: To facilitate hoisting, transverse reinforcing bars are welded through the inner side of the upper wave of the web reinforcement 130 in the longitudinal direction, and the thin-walled plate is hoisted through the transverse reinforcing bars.

[0042] In the actual use of the steel truss thin-walled slab with no need to measure the bottom formwork height according to the embodiment of this application, the steel truss body 100 and the steel mesh are welded together according to the above structure. Then, concrete is poured at the lower end of the steel mesh and the steel truss body 100 to form the bottom formwork 200. The pouring height of the concrete is based on the bottom end face of the standard slab 160. When the concrete is poured to the bottom end face of the standard slab 160, the concrete pouring stops. During this period, it is not necessary to measure the concrete height multiple times, thus achieving the purpose of eliminating the need to measure the concrete height.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, various modifications and variations are possible with this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
