DETAILED DESCRIPTION

[0041] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0042] Refer to the instruction manual Figures 1 to 9 A fast-type combined steel structure support for cap beam construction includes a pier 1, a hoop component 2 and a support beam component 3. The hoop component 2 includes two hoop body bodies 21, and the two hoop body bodies 21 are both installed on the pier 1. The circumference of the two hoop body bodies 21 after being assembled together is smaller than the circumference of the pier 1; the support beam component 3 includes a beam piece combination component 1 31 and a beam piece combination component 2 32, and the beam piece combination component 1 31 and the beam piece combination component 2 32 are symmetrically arranged on the hoop body body 21, and guardrail mechanisms 33 are arranged on the beam piece combination component 1 31 and the beam piece combination component 2 32.

[0043] The specific implementation scenario is: the hoop body 21 is set on the pier 1, the circumference of the two hoop body bodies 21 installed on the pier 1 is smaller than the circumference of the pier 1, and the hoop body body 21 can be stably fixed on the pier 1 during installation, and then the beam assembly component 1 31 and the beam assembly component 2 32 are respectively hoisted to the hoop body 21, and the beam assembly component 1 31 and the beam assembly component 2 32 are supported by the hoop body 21. Compared with the existing method of using a crane to hoist the components one by one to a high altitude and then assembling them, the construction efficiency is improved and the workload of the staff is reduced.

[0044] Refer to the instruction manual Figures 1 to 3 The hoop component 2 includes a reinforcing rib 22, a wing plate is arranged on the hoop body 21, the reinforcing rib 22 is fixedly arranged on the wing plate, an ear plate 23 is fixedly arranged on the hoop body 21, a platform plate 24 is fixedly arranged on the ear plate 23, and the two hoop body bodies 21 are fixedly arranged by bolts.

[0045] It should be noted that bolt holes are provided on the wing plates, and bolts are installed in the bolt holes, and the two hoop bodies 21 are fixed together by the bolt group 25 .

[0046] Refer to the instruction manual Figures 1 to 3 In order to improve the friction between the pier column 1 and the hoop body 21, specifically, a rubber pad is fixedly provided on the hoop body 21. After the hoop body 21 is installed on the pier column 1, the rubber pad fits the pier column 1, and the thickness of the rubber pad is 1 cm.

[0047] It should be noted that rubber has a certain surface roughness, which helps to increase the friction between the contact surface. When two surfaces are in contact, the actual contact area is much smaller than the apparent contact area, and the micro-roughness of rubber can increase the number of actual contact points, thereby increasing friction.

[0048] Refer to the instruction manual Figures 1 to 9 The beam assembly component 1 31 and the beam assembly component 2 32 both include a longitudinal beam 1 311, which is fixedly arranged on the platform plate 24, a transverse beam 313 is fixedly arranged on the longitudinal beam 1 311, a longitudinal beam 2 312 is fixedly arranged on the transverse beam 313, and a corresponding connecting plate 314 is fixedly arranged on the two longitudinal beams 2 312. The support beam component 3 also includes a guardrail mechanism 33, which includes a guardrail 331, a fixed plate 332 is fixedly arranged on the transverse beam 313, and the guardrail 331 is arranged on the fixed plate 332.

[0049] It should be noted that after the beam assembly component 1 31 and the beam assembly component 2 32 are respectively hoisted onto the hoop body 21, the beam assembly component 1 31 and the beam assembly component 2 32 are connected by the connecting plate 314, so that the beam assembly component 1 31 and the beam assembly component 2 32 can be quickly assembled to reduce the workload of the staff.

[0050] It should also be noted that the provision of the fixing plate 332 facilitates the installation of the guardrail 331 .

[0051] Refer to the instruction manual Figures 1 to 9 In order to ensure the safety of the workers during construction, specifically, a railing base 333 is fixedly provided on the fixing plate 332, a through hole is opened on the railing base 333, a hinge 2 335 is movably provided in the through hole, the guardrail 331 is rotatably provided on the hinge 2 335, and positioning holes are opened on the railing base 333 and the guardrail 331, a hinge 1 334 is movably installed in the positioning hole.

[0052] It should be noted that after the beam assembly component 1 31 and the beam assembly component 2 32 are hoisted, the default state of the guardrail mechanism 33 is the laid-down state, which is convenient for the staff to be located on the beam assembly component 1 31 and the beam assembly component 2 32, and then the guardrail 331 is limited by the hinge 1 334 so that the guardrail 331 is in a vertical state, and the staff on the beam assembly component 1 31 and the beam assembly component 2 32 are protected by the guardrail 331.

[0053] Refer to the instruction manual Fig.14 The construction method of the cap beam construction rapid combined steel structure support comprises the following steps:

[0054] Step 1: Install two hoop bodies 21 at a specified height position of the pier 1;

[0055] Step 2: Assemble the beam assembly component 1 31 and the beam assembly component 2 32 respectively, weld the longitudinal beam 1 311, the longitudinal beam 2 312 and the cross beam 313, and weld the fixing plate 332 to the railing base 333;

[0056] Step 3: Weld the fixing plate 332 to the crossbeam 313, keep the guardrail mechanism 33 in a laid-down state, and use a crane to hoist the beam assembly component 1 31 and the beam assembly component 2 32 to the hoop body 21 and fix them;

[0057] Step 4: The longitudinal beam 1 311 falls on the wing plate for installation, and the connecting plate 314 falls on the platform plate 24 for installation, and then the beam-piece assembly component 1 31 and the beam-piece assembly component 2 32 are fixed by the connecting plate 314;

[0058] Step 5: Stand up the guardrail mechanism 33, insert the hinge 1 334 into the positioning hole, and position the guardrail mechanism 33 through the hinge 1 334.

[0059] The hoop body 21 is a semicircular structure. When in use, the two hoop body bodies 21 are installed on the pier 1. The connecting plate 314 is supported by the platform plate 24 on the hoop body 21. Therefore, the connection between the platform plate 24 and the hoop body 21 needs to be very firm, that is, the ear plate 23 needs to be welded to the hoop body 21, the platform plate 24 is welded to the ear plate 23, and the ear plate 23 is welded to the hoop body 21. During the welding process, the hoop body 21 is first positioned, and then the ear plate 23 is placed at the specified position of the hoop body 21, and then the contact position between the hoop body 21 and the ear plate 23 is welded. However, when the hoop body 21 and the ear plate 23 are welded, the metal in the weld area and its vicinity is heated to a very high temperature, which will cause thermal expansion of this part of the metal, and the metal in the welding area will produce internal stresses. These stresses are caused by the expansion of the metal when heated and the inability to shrink freely when cooled. When these stresses exceed the yield strength of the material, plastic deformation will occur, that is, after the ear plate 23 is welded to the hoop body 21, the hoop body 21 will be deformed, making it impossible to be installed on the pier 1. In order to avoid the above situation, the hoop body 21 needs to be adjusted when welding the ear plate 23 on the hoop body 21. Refer to the attached manual. Figures 10 to 13Specifically, a kind of rapid combined steel structure support processing equipment for cap beam construction, the processing equipment is used for rapid combined steel structure support for cap beam construction, including a box body 4, a support platform is arranged in the box body 4, a workpiece 1 is placed on the support platform, a positioning component 6 is arranged on the support platform, the positioning component 6 includes a support seat 63, an electric heating wire is fixedly arranged on the support seat 63, the support seat 63 is used to support the workpiece 1, a positioner 7 is arranged in the box body 4, the positioner 7 clamps the workpiece 2, a welding mechanism 5 is arranged in the box body 4, the welding mechanism 5 includes a welding gun 51, and the welding gun 51 is used to weld the contact position between the workpiece 1 and the workpiece 2.

[0060] It should be noted that workpiece 1 is the hoop body 21, workpiece 2 is the ear plate 23, a linear drive is fixedly provided on the support platform, a positioning seat is fixedly provided on the output shaft of the linear drive, the linear drive is configured as a cylinder, after workpiece 1 is placed on the support platform, the output shaft of the cylinder moves toward workpiece 1 to position workpiece 1, the positioner 7 is configured as a robotic arm, a negative pressure suction nozzle is fixedly provided on the end effector of the robotic arm, an air pump is fixedly connected to the negative pressure suction nozzle, and negative pressure suction is generated on the negative pressure suction nozzle after the air pump is started. The negative pressure suction nozzle, the air pump and the robotic arm are mature existing technologies and are not described in detail here. A lifter is also provided in the pier 1, the lifter is vertically provided in the pier 1, the placement platform is fixedly provided on the output shaft of the lifter, the lifter is used to adjust the height of the support platform in the pier 1, and the lifter is configured as a linear motor.

[0061] It should also be explained that workpiece 1 is placed on the support table, and the support seat 63 supports the curved surface of workpiece 1. Then, workpiece 1 is positioned by a linear drive so that workpiece 1 fits tightly with the support seat 63. Then, the electric heating wire is turned on to preheat workpiece 1 and increase the temperature of workpiece 1. By adjusting the height of the support table, the end effector of the positioner 7 positions workpiece 2, and workpiece 1 and workpiece 2 are fit together. Then, the fitting area is welded by the welding gun 51. Since the temperature of workpiece 1 is increased before welding, workpiece 1 will not generate local high temperature during welding. The overall slow drop in temperature of workpiece 1 can avoid deformation caused by stress changes. In addition, workpiece 1 is fixed to the support seat 63, and the support seat 63 can support workpiece 1 to further prevent deformation of workpiece 1.

[0062] Refer to the instruction manual Figures 10 to 13Since the specifications of the pier 1 are different, that is, the circumference of the pier 1 is different, the circumference of the workpiece 1 that matches the pier 1 is also different. In order to adapt to the circumference of different workpieces, the support seat 63 can stably support and limit the workpiece 1 to prevent the welding deformation of the workpiece 1. Specifically, the positioning component 6 includes a support frame 61, the support frame 61 is fixedly arranged on the support platform, a sliding seat 62 is slidably arranged on the support frame 61, the support seat 63 is fixedly arranged on the sliding seat 62, a gear 1 64 is rotatably arranged on the support frame 61, a guide hole 641 is opened on the gear 1 64, a connecting shaft 65 is fixedly arranged on the sliding seat 62, and the connecting shaft 65 is slidably arranged on the guide hole 641. A gear 2 66 is rotatably arranged on the support frame 61, and the gear 2 66 is meshed with the gear 1 64.

[0063] It should be noted that a motor is fixedly mounted on the support frame 61 , and the second gear 66 is fixedly mounted on the output shaft of the motor.

[0064] It should also be noted that, when the motor is started, the rotation of the motor output shaft drives gear 2 66 to rotate, and gear 2 66 meshes with gear 1 64 to drive gear 1 64 to rotate. The rotation of gear 1 64 drives the connecting shaft 65 to slide, and the sliding seat 62 is driven to slide under the traction of the connecting shaft 65. The sliding of the sliding seat 62 then drives the support seat 63 to move, thereby achieving the effect of adjusting the position distance of the support seat 63, and the support area of ​​the support seat 63 can be adjusted according to the specifications of the workpiece 1.

[0065] Refer to the instruction manual Figures 10 to 13 In order to facilitate driving the welding gun 51 to move, specifically, the welding mechanism 5 includes a fixed seat 52, which is fixedly arranged on the top inner wall of the box body 4, an adjusting seat 54 is slidably arranged in the fixed seat 52, a fixed seat 55 is fixedly arranged on the adjusting seat 54, an adjusting seat 2 56 is slidably arranged on the fixed seat 2 55, and the welding gun 51 is fixedly arranged on the adjusting seat 2 56.

A threaded rod is fixedly arranged on the output shaft of the rotating driver 53, and the adjusting seat 54 is threadedly connected to the threaded rod. A motor is also fixedly arranged on the fixed seat 55, and a screw rod is fixedly arranged on the output shaft of the motor, and the adjusting seat 56 is threadedly connected to the screw rod. The rotating driver 53 and the motor on the fixed seat 55 are used to drive the welding gun 51 to move horizontally left and right and horizontally forward and backward.

[0067] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
