Description

Technical Field

[0001] The present invention relates to the field of construction, and particularly to a corrugated web steel-concrete flexural member with crimped flanges and a production method thereof. Background Art

[0002] Steel-concrete flexural members (also known as PEC members) are often used in construction together with steel-concrete columns (PEC columns). The existing PEC flexural members mainly include I-beams and concrete cast on both sides of the web of the I-beam. Since the I-beam itself is a section steel with a non-closed cross-section, the binding force of the I-beam on the internal concrete is limited. When the flexural member undergoes large deformation, problems such as the separation of the section steel from the concrete and the cracking and spalling of the concrete are likely to occur. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the existing steel-concrete flexural members use section steels with non-closed cross-sections, and when the flexural members are deformed greatly, it is easy to cause the separation of the section steel from the concrete and thus lead to the failure of the cross-section.

[0004] To solve the above technical problem, the technical solution adopted by the present invention is: a corrugated web steel-concrete flexural member with crimped flanges, including a steel beam, transverse stirrups and longitudinal stirrups;

[0005] The steel beam includes an upper flange, a lower flange and a web welded between the upper flange and the lower flange, and the web is wavy;

[0006] The number of the transverse stirrups is multiple. The two ends of the transverse stirrups are respectively welded to the upper flange and the lower flange, and the transverse stirrups are aligned with the concave sections of the wavy web, that is, each concave section of the wavy web corresponds to a transverse stirrup; the longitudinal stirrups are parallel to the steel beam and welded to all the transverse stirrups;

[0007] Concrete is cast on both sides of the web.

[0008] The wavy web adopted by the steel-concrete flexural member of the present invention can form longitudinal restraint on the concrete in the steel beam, improve the bonding force between the concrete and the steel beam, reduce the possibility of the concrete coming off and spalling when the member is bent, and improve the strength of the member. On the other hand, the steel-concrete flexural member of the present invention optimizes the position of the transverse stirrups, so that all the transverse stirrups are aligned with the concave sections of the wavy web, making up for the defect that the restraint of the wavy web on the concrete is relatively weak at the concave sections, and generating a technical effect of the coordinated work between the wavy web and the transverse stirrups to improve the strength of the member. At the same time, it can also improve the stability of the upper flange and the lower flange at the concave sections of the wavy web.

[0009] In order to facilitate the connection between the flexural member and the steel-concrete beam, flat sections are provided at both ends of the wavy web.

[0010] To further restrain the concrete, the edges of the upper flange and the lower flange are both provided with flanges.

[0011] To enhance the connection strength between the flexural member and the reinforced concrete column, stiffening plates are provided at both ends of the steel beam. The upper and lower ends of the stiffening plates are respectively welded to the flanges of the upper flange and the lower flange. When connecting to the reinforced concrete column, the stiffening plates are also welded to the reinforced concrete column.

[0012] The present invention also provides a production method for a flexural member of a steel-concrete composite structure with flanged edges and corrugated webs, comprising the following steps:

[0013] Step 1: Bend the web into a wavy shape and weld it to the upper flange and the lower flange to form a steel beam;

[0014] Step 2: Weld transverse tension bars between the upper flange and the lower flange. Each concave section of the wavy web is aligned with a transverse tension bar;

[0015] Step 3: Weld longitudinal tension bars to all the transverse tension bars, weld flanges at the edges of the upper flange and the lower flange, and weld stiffening plates at both ends of the steel beam;

[0016] Step 4: Pour concrete on both sides of the web.

[0017] In the above steps, Step 2 takes the most time, because: 1. The number of transverse tension bars is large; 2. Each transverse tension bar needs to be positioned, aligning with the concave section of the wavy web and ensuring that all transverse tension bars are in a flush position; 3. The transverse tension bars are in a suspended state during welding. Without jigs, generally, workers need to hold a transverse tension bar with one hand and weld with the other hand, which is inconvenient for operation.

[0018] To improve the operation efficiency of Step 2, the present invention uses a distributor to weld the transverse tension bars in Step 2;

[0019] The distributor comprises a base plate, a guide tube, a material taking assembly and a limiting plate. An inclined material rack is arranged on the base plate, and a plurality of transverse tension bars to be welded are in a C shape and placed on the material rack. The guide tube is in a vertical posture and fixed to the bottom surface of the base plate through a connecting frame;

[0020] The material taking assembly comprises a jacking rod, a bearing plate and a material taking plate. The jacking rod passes through the vertical guide tube, the bearing plate is fixed to the top of the jacking rod, the material taking plate is in an L shape and comprises a slope section and a vertical section. The vertical section is fixed to one side of the bearing plate, the limiting plate is vertically fixed on the base plate and located on the other side of the bearing plate. The bearing plate and the material taking plates and the limiting plate on its left and right sides form a groove capable of accommodating the transverse tension bars. A flap is hinged to the bottom of the limiting plate. The material taking plate is located below the material rack and the slope section is aligned with the foremost transverse tension bar on the material rack;

[0021] Step 2 specifically includes the following sub-steps:

[0022] Sub-step 2-1: Place the base plate of the distributor on the upper and lower flanges of the steel beam, and place a row of C-shaped transverse tension bars on the inclined rack; the bottom end of the ejector rod lands on the corrugated web;

[0023] Sub-step 2-2: Push the distributor along the length direction of the steel beam. The ejector rod climbs vertically upward under the action of the corrugated web, and the bearing plate and the material-taking plate rise together. The ramp section of the material-taking plate lifts the frontmost transverse tension bar on the rack, and then this transverse tension bar slides down along the ramp section onto the bearing plate;

[0024] Sub-step 2-3: Continue to push the distributor along the length direction of the steel beam. During the process of the distributor translating to the concave section of the corrugated web, the ejector rod, the material-taking plate, the bearing plate, and the transverse tension bar on the bearing plate continuously descend; when the ejector rod reaches the middle position of the concave section of the web, the transverse tension bar on the bearing plate is exactly aligned with the middle position of the concave section of the web; at this time, spot-weld the transverse tension bar to the upper and lower flanges;

[0025] Sub-step 2-4: Continue to push the distributor along the length direction of the steel beam, and the ejector rod starts to climb upward along the corrugated web, entering the next material-taking cycle; repeat this process until all the transverse tension bars are spot-welded;

[0026] Sub-step 2-5: After all the transverse tension bars are spot-welded, fully weld and reinforce all the transverse tension bars.

[0027] The distributor of the present invention can achieve three functions: material taking, positioning, and temporary fixing. The user only needs to push the distributor to continuously and automatically arrange the transverse tension bars at the positions aligned with the concave sections of the corrugated web, greatly improving the welding efficiency of the transverse tension bars. Moreover, the distributor of the present invention can not only improve the manual welding efficiency but also cooperate with various automatic welding equipment. The distributor automatically presents the transverse tension bars in sequence at the appropriate positions, and then the automatic welding equipment performs automated welding.

[0028] In sub-step 2-4, after the transverse tension bar is spot-welded and at the initial stage of continuing to push the distributor, the ejector rod will have a very small climb. At this time, the spot-welded transverse tension bar is still on the bearing plate, which may cause the bearing plate to not rise with the ejector rod, resulting in the distributor getting stuck. To avoid this situation, a compression section is provided in the ejector rod. The compression section is made of rubber material, and the compression section enables the ejector rod to have a compression amount of about 5 millimeters under the action of an external force, ensuring that the entire distributor can move forward smoothly; as long as the distributor can move forward about 5 millimeters in the initial stage, it can cause the spot-welded transverse tension bar to be misaligned with the bearing plate, and then the ejector rod and the bearing plate can climb freely.

[0029] To reduce the friction between the ejector rod and the corrugated web, the bottom of the ejector rod is spherical or provided with rolling elements, which can be ball bearings or rollers.

[0030] Further, a guide plate is provided on the bottom surface of the base plate. The guide plate is parallel to the steel beam. During the use of the distributor, the guide plate is attached to the upper flange or the lower flange, restricting the base plate to only translate along the length direction of the steel beam.

[0031] In the present invention, the length of the transverse tie bars is equal to the distance between the upper flange and the lower flange. Due to machining errors, some transverse tie bars may need to be subjected to a certain pressure to enter between the upper flange and the lower flange. To ensure that all transverse tie bars can smoothly descend with the bearing plate and the ejector rod, a spring is provided on the connecting frame in the present invention. The top end of the spring is connected to the material taking plate. A magnet is provided on the bottom surface of the bearing plate. The magnet can adsorb the transverse tie bars on the bearing plate, and the spring applies a downward pulling force to the material taking plate. This downward pulling force is finally transmitted to the transverse tie bars through the bearing plate and the magnet, promoting the transverse tie bars to enter between the upper flange and the lower flange.

[0032] Advantages: (1) The corrugated web used in the steel-concrete flexural member of the present invention can form longitudinal restraint on the concrete in the steel beam, improving the bonding force between the concrete and the steel beam, reducing the possibility of concrete exfoliation and spalling during bending of the member, and enhancing the strength of the member. (2) The steel-concrete flexural member of the present invention optimizes the position of the transverse tie bars, aligning all the transverse tie bars with the concave sections of the corrugated web, compensating for the relatively weak restraint of the corrugated web on the concrete at the concave sections, resulting in a technical effect of coordinated work between the corrugated web and the transverse tie bars to improve the strength of the member, and at the same time, enhancing the stability of the upper flange and the lower flange at the concave sections of the corrugated web. (3) The steel-concrete flexural member of the present invention is equipped with a distributor, realizing the triple functions of material taking, positioning, and temporary fixing. The user only needs to push the distributor to continuously and automatically arrange the transverse tie bars at the positions aligned with the concave sections of the corrugated web, greatly improving the welding efficiency of the transverse tie bars. (4) The distributor in the present invention is equipped with a spring and a magnet, applying a downward pulling force to the transverse tie bars to ensure that the transverse tie bars smoothly enter between the upper flange and the lower flange.

Detailed implementation manners

[0050] The present invention will be further described in detail below in conjunction with specific embodiments.

[0051] Embodiment 1

[0052] As Figure 1 shown, the corrugated web steel-concrete flexural member with crimped flanges in this embodiment includes a steel beam 100, transverse tension bars 200, and longitudinal tension bars 300; the steel beam 100 includes an upper flange 110, a lower flange 120, and a web 130 welded between the upper flange 110 and the lower flange 120, and the web 130 is wavy.

[0053] The number of the transverse tension bars 200 is multiple, and both ends of the transverse tension bars 200 are welded to the upper flange 110 and the lower flange 120 respectively. The transverse tension bars 200 are aligned with the concave sections of the wavy web 130, that is, each concave section of the wavy web 130 corresponds to one transverse tension bar 200; the longitudinal tension bars 300 are parallel to the steel beam 100 and welded to all the transverse tension bars 200.

[0054] Concrete is poured on both sides of the web 130. For the convenience of observation, Figure 1 the concrete is hidden in the figure.

[0055] The wavy web 130 adopted by the steel-concrete flexural member in this embodiment can form longitudinal restraint on the concrete in the steel beam 100, improve the bonding force between the concrete and the steel beam 100, reduce the possibility of concrete exfoliation and spalling when the member is subjected to bending, and improve the strength of the member. On the other hand, the steel-concrete flexural member of the present invention optimizes the position of the transverse tension bars 200, so that all the transverse tension bars 200 are aligned with the concave sections of the wavy web 130, making up for the defect that the restraint of the wavy web 130 on the concrete is relatively weak at the concave sections, and generating a technical effect of coordinated work between the wavy web 130 and the transverse tension bars 200 to improve the strength of the member. At the same time, it can also improve the stability of the upper flange 110 and the lower flange 120 at the concave sections of the wavy web 130.

[0056] In order to facilitate the connection between the flexural member and the steel-concrete beam, flat sections 131 are provided at both ends of the wavy web 130; in order to further restrain the concrete, crimps 500 are provided at the edges of the upper flange 110 and the lower flange 120; in order to enhance the connection strength between the flexural member and the steel-concrete column 600, stiffening plates 400 are provided at both ends of the steel beam 100, and the upper and lower ends of the stiffening plates 400 are welded to the crimps 500 of the upper flange 110 and the crimps 500 of the lower flange 120 respectively; when connecting with the steel-concrete column 600, the stiffening plates 400 are also welded to the steel-concrete column 600.

[0057] The production method of the corrugated web steel-concrete flexural member with crimped flanges in this embodiment includes the following steps:

[0058] Step 1: Bend the web 130 into a wavy shape and weld it to the upper flange 110 and the lower flange 120 to form the steel beam 100;

[0059] Step 2: Weld the transverse tension bars 200 between the upper flange 110 and the lower flange 120, and align each concave section of the wavy web 130 with a transverse tension bar 200;

[0060] Step 3: Weld the longitudinal tension bars 300 to all the transverse tension bars 200, weld the flanges 500 to the edges of the upper flange 110 and the lower flange 120, and weld the reinforcement plates 400 to both ends of the steel beam 100;

[0061] Step 4: Pour concrete on both sides of the web 130.

[0062] Figures 2 to 6 Shown is the distributor 700 used for welding the transverse tension bars 200 in Step 2. The distributor 700 includes a base plate 710, a guide tube 720, a material taking component 730, and a limiting plate 740; as Figure 2 and Figure 3 shown, an inclined material rack 711 is arranged on the base plate 710, and multiple transverse tension bars 200 to be welded are in a C shape and placed on the material rack 711; the guide tube 720 is in a vertical posture and is fixed to the bottom surface of the base plate 710 through a connecting frame 750; a guide plate 712 is arranged on the bottom surface of the base plate 710, the guide plate 712 is parallel to the steel beam 100, and during the use of the distributor 700, the guide plate 712 fits with the upper flange 110 or the lower flange 120, limiting the base plate 710 to only translate along the length direction of the steel beam 100.

[0063] As Figure 4 shown, the material taking component 730 includes a top rod 731, a bearing plate 732, and a material taking plate 733. The top rod 731 passes through the vertical guide tube 720, the bottom of the top rod 731 is spherical, the bearing plate 732 is fixed to the top of the top rod 731, the material taking plate 733 is in an L shape, the material taking plate 733 includes a slope section 733-1 and a vertical section 733-2, the vertical section 733-2 is fixed to one side of the bearing plate 732, the limiting plate 740 is vertically fixed on the base plate 710 and is located on the other side of the bearing plate 732. As Figure 6 shown, the bearing plate 732 and the material taking plates 733 and the limiting plate 740 on its left and right sides form a groove capable of accommodating the transverse tension bar 200; a flap 741 is hinged to the bottom of the limiting plate 740; the material taking plate 733 is located below the material rack 711 and the slope section 733-1 is aligned with the foremost transverse tension bar 200 on the material rack 711;

[0064] Step 2 specifically includes the following sub-steps:

[0065] Sub-step 2-1: AsFigure 7 As shown, the base plate 710 of the distributor 700 is placed on the upper flange 110 and the lower flange 120 of the steel beam 100, and a row of C-shaped transverse tie bars 200 are placed on the inclined rack 711; as Figure 8 shown, the bottom end of the ejector rod 731 lands on the corrugated web 130;

[0066] Step 2-2: As Figure 9 shown, the distributor 700 is pushed along the length direction of the steel beam 100. The ejector rod 731 climbs vertically upward under the action of the corrugated web 130, and the bearing plate 732 and the material taking plate 733 rise together. As Figure 13 shown, the ramp section 733-1 of the material taking plate 733 jacks up the foremost transverse tie bar 200 on the rack 711. After that, as Figure 10 and Figure 14 shown, this transverse tie bar 200 slides down along the ramp section 733-1 onto the bearing plate 732;

[0067] Step 2-3: As Figure 11 shown, continue to push the distributor 700 along the length direction of the steel beam 100. During the process of the distributor 700 translating to the concave section of the corrugated web 130, the ejector rod 731, the material taking plate 733, the bearing plate 732 and the transverse tie bar 200 falling on the bearing plate 732, as Figure 15 shown, continuously descend; when the ejector rod 731 reaches the middle position of the concave section of the web 130, the transverse tie bar 200 on the bearing plate 732 is exactly aligned with the middle position of the concave section of the web 130; at this time, the transverse tie bar 200 is spot welded to the upper flange 110 and the lower flange 120;

[0068] Step 2-4: As Figure 12 shown, after the spot welding is completed, continue to push the distributor 700 along the length direction of the steel beam 100. During this process, the spot welded transverse tie bar 200 will cause the flap 741 at the bottom of the limit plate 740 to turn over, ensuring that the bearing plate 732 can be separated from the transverse tie bar 200; after that, the ejector rod 731 starts to climb upward along the corrugated web 130 and enters the next material taking cycle; repeat this way until all the transverse tie bars 200 are spot welded;

[0069] Step 2-5: After all the transverse tie bars 200 are spot welded, full welding reinforcement is carried out on all the transverse tie bars 200.

[0070] From Figure 12It can be seen that after the horizontal tie bars 200 are spot-welded, during the initial stage of continuously pushing the distributor 700, the ejector rod 731 will have a very small upward movement. At this time, the horizontally spot-welded tie bars 200 are still on the bearing plate 732, which may cause the bearing plate 732 to fail to rise with the ejector rod 731, resulting in the jamming of the distributor 700. However, this situation does not necessarily occur. If there is a short smooth stroke at the bottom of the concave section of the corrugated web 130, this phenomenon can be avoided. In order to ensure that the distributor 700 will never jam in this embodiment, a compression section is provided in the ejector rod 731. The compression section is made of rubber material, and the compression section enables the ejector rod 731 to have a compression amount of about 5 mm under the action of external force, ensuring that the entire distributor 700 can move forward smoothly. As long as the distributor 700 can move forward about 5 mm in the initial stage, the horizontally spot-welded tie bars 200 can be misaligned with the bearing plate 732, and then the ejector rod 731 and the bearing plate 732 can climb freely.

[0071] The distributor 700 of this embodiment can realize the triple functions of material taking, positioning, and temporary fixing. The user only needs to push the distributor 700 to continuously and automatically arrange the horizontal tie bars 200 at the positions aligned with the concave sections of the corrugated webs 130. The workers only need to focus on welding and do not need to consider the problem of placing the horizontal tie bars 200 at the current welding position at all, which greatly improves the welding efficiency of the horizontal tie bars 200. Moreover, the distributor 700 of this embodiment can not only improve the manual welding efficiency but also cooperate with various automatic welding devices. The horizontal tie bars 200 are automatically presented at the appropriate positions in sequence through the distributor 700, and then automated welding is performed by the automatic welding devices.

[0072] Embodiment 2

[0073] In Embodiment 1, the length of the horizontal tie bars 200 is equal to the distance between the upper wing plate 110 and the lower wing plate 120. Due to the existence of processing errors, some horizontal tie bars 200 may need to be applied with a certain pressure to enter between the upper wing plate 110 and the lower wing plate 120. To ensure that all horizontal tie bars 200 can smoothly descend with the bearing plate 732 and the ejector rod 731, as Figure 16 shown, in this embodiment, a spring 760 is provided on the connecting frame 750, and the top end of the spring 760 is connected to the material taking plate 733; a magnet 770 is provided on the bottom surface of the bearing plate 732; the magnet 770 can adsorb the horizontal tie bars 200 on the bearing plate 732, and the spring 760 applies a downward pulling force to the material taking plate 733. This downward pulling force is finally transmitted to the horizontal tie bars 200 through the bearing plate 732 and the magnet 770 to promote the horizontal tie bars 200 to enter between the upper wing plate 110 and the lower wing plate 120.

[0074] Although the embodiments of the present invention are described in the specification, these embodiments are only for reference and should not limit the protection scope of the present invention. All kinds of omissions, substitutions and changes within the scope not departing from the gist of the present invention should be included in the protection scope of the present invention.
