Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a steel truss processing equipment and processing method. Background Technology

[0002] A steel truss is a truss structure composed of steel bars, widely used in construction engineering. It is used in roof systems for large-span buildings such as industrial plants and warehouses, bearing roof loads and transferring them to the supporting structure. It can also serve as a new type of floor slab component, forming the floor slab structure together with concrete and other materials. During construction, it bears wet concrete and construction loads, and during service, it acts as the reinforcing steel in the floor slab. A steel truss typically consists of one top chord, two bottom chords, and two web bars. The web bars are wavy and used to connect the top and bottom chords. Traditionally, steel trusses are constructed by manually welding and fixing the web bars, top chord, and bottom chords. However, this method makes it difficult to position the web bars, top chord, and bottom chords, leading to errors and poor welding stability. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects of the prior art and provide steel truss processing equipment and processing methods, which can position the upper chord, lower chord and web reinforcement according to design requirements, thereby improving the stability and accuracy of subsequent welding.

[0047] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0048] The steel truss processing equipment and processing method of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0049] Please see Figures 1-5 As shown, the steel truss processing equipment includes:

[0050] Strip base 1;

[0051] The first arc plate 2 provides longitudinal support for the upper chord reinforcement 20 of the steel truss. The first arc plate 2 is height-adjustably connected to the top of the strip base 1. The arc of the first arc plate 2 is less than 180 degrees.

[0052] Two second arc plates 3 are provided for longitudinal support of the two lower chord bars 21 of the steel truss. The two second arc plates 3 are respectively connected to the two ends of the strip base 1 in an adjustable manner along the lateral direction. The arc of the second arc plate 3 is less than 180 degrees.

[0053] Two hooks 18 are provided for the top ends of the two web bars 22 of the steel truss to be hung, and the two hooks 18 are respectively connected to opposite sides on the transverse side of the first arc plate 2;

[0054] Two pushing devices are used to push the two ribs 22 to swing around the longitudinal axis with the hook 18 as the fulcrum. The fixed part of the two pushing devices is connected to the top of the strip base 1, and the telescopic part is arranged opposite each other in the transverse direction. When the rib 22 is swinging and the upper chord 20 is placed longitudinally in the first arc plate 2, the top of the rib 22 is always attached to the upper chord 20.

[0055] By limiting the curvature of both the first arc plate 2 and the second arc plate 3 to less than 180 degrees, the contact between the web rib 22 and the upper chord rib 20 and the lower chord rib 21 is not blocked by the first arc plate 2 and the second arc plate 3, which facilitates subsequent abutment welding.

[0056] Specifically, when using the processing equipment to process the steel truss, two processing equipment are provided, and the first arc plate 2 and the second arc plate 3 on the two processing equipment are adjusted synchronously. Then, the upper chord 20 is placed on the two first arc plates 2 of the two processing equipment, the lower chord 21 is placed on the two corresponding second arc plates 3 of the two processing equipment, and the web reinforcement 22 is hung on the two corresponding hooks 18 of the two processing equipment. Then, the pushing device on the two processing equipment is activated synchronously to push the web reinforcement 22 to the designed position.

[0057] Because the upper chord 20, the lower chord 21, and the web rib 22 have a large span, two processing devices are installed to prevent the upper chord 20 and the lower chord 21 from bending due to their large span when they are in a resting state, which would affect the welding quality.

[0058] Specifically, an alignment assembly is connected between the two processing devices, the alignment assembly comprising:

[0059] Two limiting ear plates 16 are respectively connected to the same position on the top of the two strip bases 1 of the processing equipment;

[0060] An alignment rod 19 is inserted between the two limiting ear plates 16, and each of the two limiting ear plates 16 has a through hole for the alignment rod 19 to pass through.

[0061] By setting up this alignment component, the two processing devices are ensured to be flush at both ends during use, thus improving the subsequent welding accuracy.

[0069] A first motor 12 is used to drive the first lead screw 10 to rotate, and the first motor 12 is connected to the sleeve 8.

[0070] The first motor 12 drives the first lead screw 10 to rotate, which in turn drives the first drive block 11 to move vertically, and in turn drives the core rod 9 to move vertically.

[0071] Specifically, the body of the first motor 12 is connected to the top of the sleeve 8 on the side relatively close to the first lead screw 10. The motor shaft of the first motor 12 is set downward and coaxially connected to the first lead screw 10. A first fixing plate is connected to the bottom of the sleeve 8 on the side relatively close to the first lead screw 10. The first lead screw 10 is rotatably connected to the first fixing plate.

[0072] By setting the first fixed plate, the rotational stability of the first lead screw 10 is ensured.

[0073] Preferably, a sliding device is connected between the two second arc plates 3 and the strip base 1, the sliding device comprising:

[0074] Two movable seats 4, and two second arc plates 3 are respectively connected to the two movable seats 4;

[0076] A second driving member is used to drive the two slide rods 17 to slide along the corresponding slide groove. The second driving member is connected to the opposite outer side of the strip base 1.

[0077] Specifically, a hydraulic rod is also connected between the second arc plate 3 and the corresponding movable seat 4.

[0078] By connecting the hydraulic rod between the second arc plate 3 and the corresponding movable seat 4, the height of the second arc plate 3 can be adjusted to meet various layout requirements of the lower chord rib 21, thus improving practicality.

[0079] Preferably, the second drive component includes:

[0080] A bidirectional lead screw 13 is arranged laterally on the opposite outer side of the strip base 1;

[0081] Two second drive blocks 14 are respectively screwed onto the two threaded sections of the bidirectional lead screw 13, and one side is respectively connected to the two slide rods 17. The strip base 1 has a second sliding groove on the side closer to the bidirectional lead screw 13 for the two second drive blocks 14 to slide through.

[0082] A second motor 15 is used to drive the bidirectional lead screw 13 to rotate, and the second motor 15 is connected to the strip base 1.

[0083] Specifically, the body of the second motor 15 is connected to one end of the strip base 1 that is relatively close to the bidirectional lead screw 13. The motor shaft of the second motor 15 is set towards the other end and is coaxially connected to the bidirectional lead screw 13. The other end of the strip base 1 that is relatively close to the bidirectional lead screw 13 is connected to a second fixing plate. The bidirectional lead screw 13 is rotatably connected to the second fixing plate.

[0084] By setting the second fixing plate, the rotational stability of the bidirectional lead screw 13 is improved.

[0085] Preferably, the bottom of both movable seats 4 is connected to a set of casters 5.

[0086] By setting the universal wheel set 5, the slide rod 17 can drive the movable seat 4 to move.

[0087] Preferably, the pushing device includes:
