Description

Technical Field

[0001] The invention relates to the field of construction, and in particular to a corrugated plate steel-concrete beam suitable for heavy industrial buildings and a production method thereof. Background Art

[0002] In traditional buildings, most of the work needs to be completed on site. Problems such as long construction period, serious environmental pollution, large stockpiling site, and shortage of construction workers have become barriers to the progress of the construction industry. Although prefabricated buildings have advantages in terms of construction, there are still some problems that cannot be ignored, such as the reliability of the vertical nodes of the PC structure, cracking and water leakage of the steel and composite structure enclosure walls, etc. In addition, prefabricated buildings are usually expensive, resulting in poor satisfaction of owners and users with prefabricated buildings. Although steel structures have relatively reliable node structures and their construction quality is easy to guarantee, steel structures themselves have problems such as poor sound insulation and heat preservation, low rigidity, poor comfort, and the need for additional fire prevention and anti-corrosion treatment. The steel-concrete composite structure has the advantages of both structures. Most of its main body is covered with concrete, and it has the same connection nodes as the steel structure. The H-shaped steel beam in the steel-concrete composite beam (referred to as the steel-concrete beam) mainly bears bending moment. The best way to improve the bending bearing capacity is to increase the web height and reduce the web thickness, but the web is easy to buckle under the action of shear force, and its deformation is not easy to control during transportation and installation. In order to improve the shear bearing capacity and stiffness of the components, it is generally necessary to increase the thickness of the web or set stiffening ribs to improve the stability of the web. This not only increases the amount of steel used in the component, but also increases the construction workload. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a new type of corrugated plate steel-concrete beam to increase the stiffness of the steel-concrete beam and control the steel consumption and construction workload of the component, and at the same time provide a corresponding production method to improve the production efficiency of the new type of corrugated plate steel-concrete beam.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a corrugated plate steel-concrete beam suitable for heavy industrial buildings, comprising a wing plate, an intermediate web plate and a tie steel mesh;

[0005] The intermediate web comprises a corrugated web and straight webs welded to both ends of the corrugated web, and web holes for node connection are arranged on the straight webs;

[0006] The middle web connects two parallel wing plates to form an I-shaped steel beam, the tie steel mesh is fixed between the wing plates, a tie steel mesh is arranged on each side of the middle web, and concrete is poured on both sides of the middle web.

[0007] The wavy web enables the entire middle web to have out-of-plane buckling resistance, thereby improving the stiffness of the steel-concrete beam while keeping the amount of steel basically unchanged.

[0008] Since the middle web of the present invention mainly adopts a corrugated web, the waves of the corrugated web occupy part of the beam width, resulting in insufficient welding length between the traditional C-shaped tie bars and the wing plates. In order to overcome this problem, the tie steel mesh includes straight vertical tie bars, horizontal anti-cracking bars and horizontal connecting bars. All vertical tie bars are parallel to each other and welded to the horizontal anti-cracking bars. Two horizontal connecting bars are respectively welded to the two ends of the vertical tie bars. The tie steel mesh is welded to the wing plates through the horizontal connecting bars.

[0009] Furthermore, the corrugated web and the straight web are welded by full penetration welding. The thickness of the corrugated web is 2-6 mm. The wave height and wave pitch of the corrugated web can be determined according to the actual processing capacity. Generally, the recommended wave height is ±20 mm and the wave pitch is 155 mm. The length of the straight web is not less than one beam height.

[0010] The present invention also provides a method for producing a corrugated plate steel-concrete beam suitable for heavy industrial buildings, comprising the following steps:

[0011] Step 1: Weld straight webs at both ends of the wavy web to form an intermediate web, and weld the intermediate web to the wing plate to form an I-shaped steel beam;

[0012] Step 2: Processing a pouring auxiliary tool, the pouring auxiliary tool comprising a support assembly, a support column and an integrated template, the support assembly comprising a base plate and a support beam, the base plate is provided with a locking assembly and a fixing hole, the support column is installed in the locking assembly, and the support beam is installed on the base plate; the integrated template is semicircular, and the straight edge of the integrated template is provided with two wing plate grooves aligned with the wing plate and a plurality of steel bar grooves aligned with the horizontal anti-cracking reinforcement and the horizontal connecting reinforcement;

[0013] Step 3: Fix the support assembly to the web hole of the straight web through the fixing holes and bolts. Support assemblies are arranged on both sides of each straight web; insert the wing plate groove of the integrated template into the wing plate, and fix the integrated template to the base plate;

[0014] Step 4: Weld the vertical tie bars, horizontal anti-cracking bars and horizontal connecting bars to form a tie steel mesh;

[0015] Step 5: Transport the processed and assembled I-shaped steel beam and pouring auxiliary tools to the pouring site. The integrated formwork at the lower layer of the I-shaped steel beam supports the I-shaped steel beam at both ends, and the support column assists in supporting the I-shaped steel beam to ensure that the straight web of the I-shaped steel beam remains horizontal;

[0016] Step 6: Remove the integrated formwork on the upper layer of the I-shaped steel beam, place the tie steel mesh on the support beam of the support assembly, and then weld the horizontal connecting ribs of the tie steel mesh to the flange plate;

[0017] Step 7: Reinsert the removed integrated formwork, the integrated formwork and the wing plate form a casting cavity with the opening facing upward, and the tie steel mesh is located in the casting cavity;

[0018] Step 8: pouring concrete into the pouring cavity;

[0019] Step 9: After the poured concrete solidifies and reaches 70% of the design strength, remove the support column; then push the steel-concrete beam to roll so that the surface of the middle web that is not poured with concrete faces upward; then reinstall the support column for auxiliary support;

[0020] Step 10: Repeat steps 6-8 to pour concrete on the other side of the middle web;

[0021] Step 11: After the concrete solidifies, remove the pouring auxiliary tools.

[0022] In the traditional steel-concrete beam casting process, if the steel-concrete beam is cast on both sides, the steel-concrete beam must be turned over by a hoist after one side is cast, which requires the casting site to be equipped with a corresponding large hoist or a road for the crane to pass through, limiting the production efficiency of the steel-concrete beam. The production method of the present invention installs a semicircular integrated template at both ends of the I-shaped steel beam, so that the steel-concrete beam has the ability to roll over. The production unit can use manpower or a small winch to drive the steel-concrete beam to roll 180°, making the casting operation of the steel-concrete beam more convenient and flexible.

[0023] Specifically, the locking assembly includes a conical tube, a locking nut and a steel ball. The conical tube is fixed on a base plate. The outer surface of the conical tube is provided with a thread. The locking nut is threadedly connected to the conical tube. The support column passes through the conical tube and the locking nut. The steel ball is located in the gap between the support column and the conical tube. A circle of ball pressing ring is provided in the locking nut to press the steel ball. After loosening the locking nut, the bead pressing ring does not exert pressure on the steel ball, and the steel ball can move freely in the gap between the support column and the tapered tube. At this time, the steel ball has no binding force on the support column, and the support column can move freely in the tapered tube, which is convenient for workers to adjust the position of the support column so that the support column can provide reasonable support for the I-shaped steel beam and ensure that the middle web of the I-shaped steel beam is in a horizontal posture; when the support column is adjusted to a reasonable position, the worker tightens the locking nut, and the bead pressing ring presses the steel ball tightly into the wedge-shaped gap between the support column and the tapered tube and locks the support column. This wedge-shaped gap enables the steel ball and the support column to have self-locking ability. The greater the axial force applied to the support column, the stronger the locking effect of the steel ball on the support column.

[0024] Furthermore, a guide column is provided on the base plate, and a thread is provided on the surface of the guide column and a support nut is installed. A guide hole is provided on the support beam, and the guide column is inserted into the guide hole. The support beam falls on the support nut, and the height of the support beam can be adjusted by rotating the support nut; the position of the tie steel mesh in the I-beam can be adjusted by adjusting the height of the support beam; the support beam is used to temporarily support the tie steel mesh, which is convenient for workers to weld the tie steel mesh to the I-beam.

[0025] Furthermore, the base plate is provided with studs, the outer surface of the integrated template is provided with a tongue plate, the tongue plate is provided with connecting holes, and the integrated template is fixed to the base plate through the tongue plate and the studs.

[0026] Furthermore, in step 7, wooden strips are used to fill the steel bar grooves of the integrated formwork.

[0027] Beneficial effects: (1) The corrugated plate steel-concrete beam of the present invention adopts a corrugated web in the middle web, so that the entire middle web has the ability to resist out-of-plane buckling, thereby improving the stiffness of the steel-concrete beam while keeping the amount of steel basically unchanged, making the steel-concrete beam more suitable for heavy industrial buildings. (2) The corrugated plate steel-concrete beam of the present invention is equipped with horizontal connecting bars in the tie steel mesh, which can not only meet the welding requirements of the tie steel mesh but also adapt to the special shape of the corrugated web. (3) The production method of the corrugated plate steel-concrete beam of the present invention adopts a semicircular integrated template as the side template of the casting cavity, which can not only meet the casting requirements but also enable the steel-concrete beam to have the ability to roll, which is convenient for the production unit to perform double-sided casting and improve production efficiency. (4) The production method of the corrugated plate steel-concrete beam of the present invention adopts a conical tube, a locking nut and a steel ball to realize the translation and locking of the support column, ensuring that the steel-concrete beam can both roll and control its own posture, and ensuring that the middle web of the I-beam steel beam receives concrete pouring in a horizontal posture.

All the vertical tie bars 310 are parallel to each other and welded to the horizontal anti-cracking bars 320. The density of the vertical tie bars 310 is determined according to needs. Two horizontal connecting bars 330 are respectively welded to the two ends of the vertical tie bars 310. The tie steel mesh 300 is welded to the wing plate 100 through the horizontal connecting bars 330.
