In the case where the straightness of the steel frame is easily affected by the weight of the steel frame itself and deflection occurs, before the steel frame is manufactured, the flatness of the second supporting surface can also be changed to form a deflection on the second supporting surface, so that the upper chord or the lower chord on the second supporting surface is deflected. After the steel frame is manufactured, the deflection of the upper chord or the lower chord of the steel frame due to the adjustment of the auxiliary tooling can offset the deflection of the steel frame due to its own weight, and finally a steel frame with better straightness is obtained, and the straightness of the obtained steel frame is improved to ensure the stable use of the steel frame, which to a certain extent solves the technical problem that the reliability of the steel frame during use is not ideal.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0044] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0046] In the related art, the steel frame includes an upper chord, a lower chord and a plurality of intermediate components. Some steel frames need to ensure the straightness between the upper chord and the lower chord during the manufacturing process. However, due to the complex structure of the steel frame itself, it is difficult to control the straightness between the upper chord and the lower chord of the steel frame. Moreover, for a steel frame with a certain deadweight and length, the steel frame is prone to bend in the middle of its own length due to its own deadweight, causing the steel frame to have deflection as a whole. The straightness of the steel frame is not easy to ensure, and the straightness of the steel frame finally obtained is not ideal, which will affect the stable use of the steel frame, and there is a technical problem that the cost quality of the steel frame is not ideal. The embodiment of the present application provides an auxiliary tooling and a steel frame manufacturing method, which can at least solve the above technical problems to a certain extent.

[0047] The present application will be described below with reference to the accompanying drawings:

[0048] Figure 1 A schematic diagram showing the use status of an auxiliary tool in some embodiments or certain embodiments of the present application is shown. Figure 2 A side view of an auxiliary tooling in some embodiments or certain embodiments of the present application is shown, with reference to Figure 1 and Figure 2 , the embodiment of the present application provides an auxiliary tooling, including:

[0049] Support member 1.

[0050] The positioning frame 2 is connected to the supporting member 1 and is provided with a first supporting surface 21 facing away from the supporting member 1 .

[0051] The adjusting member 3 and at least two telescopic mechanisms 4 are connected to the supporting member 1 side by side. The adjusting member 3 is supported by at least two telescopic mechanisms 4. The adjusting member 3 is provided with a second supporting surface 31 away from the supporting member 1. The telescopic mechanisms 4 are used to telescopically adjust the flatness of the second supporting surface 31.

[0052] The support member 1 in the auxiliary tooling is supported on the ground or a fixed platform, and the support member 1 provides support and installation space for other structures. The positioning frame 2 is connected to the support member 1, and is provided with a first support surface 21 away from the support member 1, so that the upper chord 101 or the lower chord 103 of the steel frame 10 can be placed and supported on the first support surface 21, and the adjustment member 3 is supported to the support member 1 through at least two telescopic mechanisms 4, and at least two telescopic mechanisms 4 can be connected side by side between the adjustment member 3 and the support member 1, and the adjustment member 3 is provided with a second support surface 31 away from the support member 1, then the remaining lower chord 103 or upper chord 101 in the steel frame 10 can be placed and supported on the second support surface 31, completing the basic positioning of the upper chord 101 and the lower chord 103 of the steel frame 10, and the positioning frame 2 has a certain hole or space, and the intermediate member 102 connecting the upper chord 101 and the lower chord 103 in the steel frame 10 can pass through the positioning frame 2 to connect the upper chord 101 and the lower chord 103, and the overall manufacturing of the steel frame 10 can be completed. Furthermore, the telescopic mechanism 4 can be used to telescopically adjust the flatness of the second support surface 31, so that the length direction of the steel frame 10 can be placed and supported on the auxiliary tooling along the arrangement direction of the telescopic mechanism 4, and then according to the needs of the steel frame 10 in the manufacturing process, different telescopic mechanisms 4 are telescoped to make the distances between the adjustment member 3 and the support member 1 at different positions the same or different, so as to change the flatness of the second support surface 31. For example, the second support surface 31 can be adjusted to be close to parallel with the first support surface 21, so as to control the overall straightness of the steel frame 10 in the manufacturing process. When the straightness of the steel frame 10 is easily affected by the weight of the steel frame 10 itself, In the case of deflection due to the influence of the amount of weight, before the steel frame 10 is manufactured, the flatness of the second supporting surface 31 can also be changed to make the second supporting surface 31 deflect, so that the upper chord 101 or the lower chord 103 on the second supporting surface 31 is deflected. After the steel frame 10 is manufactured, the deflection of the upper chord 101 or the lower chord 103 of the steel frame 10 adjusted by the auxiliary tooling can offset the deflection of the steel frame 10 caused by its own weight, and finally a steel frame 10 with better straightness is obtained, and the straightness of the obtained steel frame 10 is improved to ensure the stable use of the steel frame 10, which to a certain extent solves the technical problem that the reliability of the steel frame 10 during use is not ideal.

[0053] Furthermore, the second supporting surface 31 is located on the adjusting member 3, and the adjusting member 3 is supported to the supporting member 1 by at least two telescopic mechanisms 4. The position of the adjusting member 3 relative to the supporting member 1 can also be adjusted and changed by the telescopic mechanism 4. The telescopic mechanism 4 can be extended and retracted to adjust the second supporting surface 31 to an appropriate position, so as to be suitable for manufacturing different types of steel frames 10 and have a certain degree of versatility.

[0054] It should be noted that when different telescopic mechanisms 4 are extended and retracted to form deflection on the second supporting surface 31 , the flatness of the second supporting surface 31 is also being adjusted. Figure 1 The steel frame 10 is shown in FIG. Figure 1 The steel frame 10 is in an inverted state. Figure 1 The structure of the positioning frame 2 is not shown.

[0055] In some or certain embodiments, the second supporting surface 31 is located between the first supporting surface 21 and the supporting member 1 .

[0056] The second support surface 31 is located between the first support surface 21 and the support member 1. The first support surface 21 and the second support surface 31 provide relatively stable support for most of the steel frame 10, which is conducive to the stable manufacturing of the steel frame 10. The assembly and straightness control of the steel frame 10 where the upper chord 101 and the lower chord 103 are opposite can be realized, and the assembly and straightness control of the steel frame 10 where the upper chord 101 and the lower chord 103 are somewhat staggered can also be realized.

[0057] In some or certain embodiments, there may be a certain positional stagger between the first supporting surface 21 and the second supporting surface 31 , which may also be applicable to manufacturing a steel frame 10 with a certain misalignment between the upper chord 101 and the lower chord 103 .

[0058] In some or certain embodiments, the second supporting surface 31 may have a length dimension, and at least two telescopic mechanisms 4 are spaced apart and distributed along the length direction of the second supporting surface 31 .

[0059] The second support surface 31 has a length dimension, and at least two telescopic mechanisms 4 are spaced apart along the length direction of the second support surface 31. The length direction of the upper chord 101 and the lower chord 103 can be placed and supported on the second support surface 31 along the length direction of the second support surface 31, and then different telescopic mechanisms 4 are telescoped to adjust the flatness of the second support surface 31. The maximum area required for the second support surface 31 can be reduced to reduce the maximum area required for the adjustment member 3, reduce the manufacturing cost, and facilitate the control of the straightness of the steel frame 10.

[0060] In some or certain embodiments, the first support surface 21 may also have a length dimension, and the length direction of the first support surface 21 extends along the length direction of the second support surface 31. This facilitates manufacturing of a steel frame 10 with an upper chord 101 and a lower chord 103 opposite to each other and having a certain length.

[0061] In some or certain embodiments, the shape and specific size of the first support surface 21 and the second support surface 31 can be set according to the steel frame 10 to be manufactured. The size of the first support surface 21 and the second support surface 31 can also be set to be larger. The larger first support surface 21 and the second support surface 31 can support the smaller upper chord 101 and the lower chord 103, and then assemble the steel frame 10.

[0062] Figure 3 FIG. 1 shows a schematic diagram of a telescopic mechanism in some embodiments or certain embodiments of the present application, with reference to FIG. Figure 3 In some or certain embodiments, the telescopic mechanism 4 includes:

[0063] A connecting rod 41, one end of which is connected to the supporting member 1;

[0064] One end of the rotating sleeve 42 is threadedly sleeved on the connecting rod 41 , and the other end is in contact with the adjusting member 3 .

[0065] The connecting rod 41 is threadedly matched with the rotating sleeve 42. The end of the rotating sleeve 42 away from the connecting rod 41 is in contact with the adjusting member 3. When one end of the connecting rod 41 is connected to the supporting member 1, the rotating sleeve 42 is rotated relative to the connecting rod 41, and the connecting rod 41 does not rotate. The rotating sleeve 42 will be subjected to the axial force from the connecting rod 41, and the rotating sleeve 42 can approach or move away from the supporting member 1 along the axial direction of the connecting rod 41. The end of the rotating sleeve 42 away from the supporting member 1 will correspondingly push the adjusting member 3 to approach or move away from the supporting member 1. This type of telescopic mechanism 4 has good stability, can stably support and adjust the position of the second supporting surface 31, and ensure the position accuracy of the second supporting surface 31 finally adjusted.

[0066] In some or certain embodiments, the axial direction of the connecting rod 41 and the axis of the rotating sleeve 42 may extend in the same direction, and an angle may exist between the axis of the connecting rod 41 and the second supporting surface 31. During the movement of the rotating sleeve 42 relative to the connecting rod 41, the efficiency of pushing and changing the position of the adjusting member 3 is high.

[0067] In some or certain embodiments, the side of the adjusting member 3 close to the supporting member 1 may also be provided with an annular groove, and the other end of the rotating sleeve 42 may be inserted into the annular groove for rotational cooperation. Alternatively, the side of the adjusting member 3 close to the supporting member 1 may also be provided with a convex block, which is inserted into the other end of the rotating sleeve 42 and rotates with the rotating sleeve 42. Both can realize the rotation relative to the connecting rod 41 and the pushing of the adjusting member 3.

[0068] In some or certain embodiments, the rotating sleeve 42 may include:

[0069] The rotary structure 421 has one end coaxially threadedly sleeved on the connecting rod 41 and the other end provided with a coaxial circular groove 4211 .

[0070] The abutting portion 422 is rotatably disposed in the circular groove 4211 around the axis of the rotating structure portion 421 , and the abutting portion 422 abuts against the adjusting member 3 .

[0071] When the rotating sleeve 42 adopts this structure, the rotating structure part 421 can rotate relative to the connecting rod 41, and the abutting part 422 can also rotate relative to the rotating structure part 421. When the steel frame 10 is heavy, it is easier to drive the rotating structure part 421 to rotate, which is convenient for pushing the adjusting member 3.

[0072] In some or certain embodiments, the rotary structure 421 may include a first section 4212 and a second section 4213 that are coaxially connected, the first section 4212 being cylindrical and threadedly sleeved on the connecting rod 41, the second section 4213 being columnar and having a coaxial circular groove 4211 disposed at one end away from the first section 4212, the circular groove 4211 being coaxial with the columnar rotary abutment 422 and the two being rotatably matched. The peripheral wall of the abutment 422 may be provided with an anti-slip block 4215, the anti-slip block 4215 being located in the circular groove 4211, the second section 4213 being further away from the first section 4212 at one end thereof being provided with an anti-slip plate 4214, the anti-slip plate 4214 abutting against the anti-slip block 4215 to prevent the abutment from slipping out.

[0073] In some or certain embodiments, the second section 4213 may also have an annular groove on its inner peripheral wall, and the abutting portion 422 may have an annular protrusion on its outer peripheral wall, and the annular protrusion may be located in the annular groove, so as to achieve position limiting and anti-dropping.

[0074] In some or certain embodiments, the telescopic mechanism 4 may further include a reinforcing rib 43, and the connecting rod 41 and the support member 1 are further connected and fixed by the reinforcing rib 43. When the outer diameter of the second section 4213 is greater than the outer diameter of the first section 4212, the reinforcing rib 43 may also be connected between the second section 4213 and the first section 4212 to improve the support strength of the telescopic mechanism 4.

[0075] In some or certain embodiments, the telescopic mechanism 4 can also be set as a telescopic cylinder according to needs, and the two ends of the telescopic cylinder can be rotatably connected to the adjusting member 3 and the supporting member 1 respectively, or the telescopic mechanism 4 can also be a jack, one end of the jack is fixedly connected to the supporting member 1, and the other end of the jack supports the adjusting member 3. Both can realize the adjustment of different positions of the adjusting member 3 to adjust the flatness of the second supporting surface 31. In the case where the telescopic cylinder is hinged to the adjusting member 3, the adjusting member 3 is also supported on at least two telescopic cylinders.

[0076] In some or certain embodiments, the adjusting member 3 comprises:

[0077] The main body 32 is provided with a second supporting surface 31 .

[0078] At least two positioning portions 33 are connected to the body 32 at intervals and both protrude from the second supporting surface 31 , and a positioning space 34 is formed between two adjacent positioning portions 33 .

[0079] A second supporting surface 31 is provided on the main body 32 of the adjusting member 3, and at least two spaced positioning portions 33 are provided on the main body 32, and the positioning portions 33 are all protruding from the second supporting surface 31, then the positioning space 34 formed between two adjacent positioning portions 33 can be used to place the upper chord 101 or the lower chord 103 of the steel frame 10, thereby improving the positioning accuracy of the upper chord 101 and the lower chord 103 of the steel frame 10, and can be suitable for the manufacture of the steel frame 10 with certain requirements.

[0080] In some or certain embodiments, the body 32 may be frame-shaped, the positioning portion 33 may be block-shaped or in other shapes, two rows of positioning portions 33 may be spaced apart on the body 32, a positioning space 34 may be formed between the two rows of positioning portions 33, and the length direction of the positioning space 34 may extend along the arrangement direction of the telescopic mechanism 4. This facilitates positioning and manufacturing of a steel frame 10 having a certain length and requiring straightness.

[0081] In some or certain embodiments, the adjusting member 3 may be a rectangular plate, a surface with the largest area of ​​the adjusting plate may be configured as the second supporting surface 31, a surface of the adjusting member 3 opposite to the second supporting surface 31 may be supported by a plurality of telescopic mechanisms 4, and the plurality of telescopic mechanisms 4 may be connected to the supporting member 1 in parallel along the length direction of the adjusting member 3, or may be distributed at intervals from one end of the adjusting member 3 to the other end of the adjusting member 3, so as to facilitate the setting.

[0082] In some or certain embodiments, if the adjusting member 3 has a certain length and a certain width, at least two rows of telescopic mechanisms 4 can be set along the width direction of the adjusting member 3, and each row of telescopic mechanisms 4 is arranged side by side along the length direction of the adjusting member 3.

[0083] In some or certain embodiments, the adjusting member 3 may also be a frame-shaped or elliptical structure, and may be provided with a second supporting surface 31. The steel frame 10 may also be supported.

[0084] In some or certain embodiments, the adjusting member 3 may be a frame structure, and the positioning frame 2 may be connected to the supporting member 1 through the adjusting member 3. The relative position between the adjusting member 3 and the positioning frame 2 is easier to determine, and the positioning frame 2 may also provide a limit and guide for the adjusting member 3, and the overall stability of the auxiliary tooling is also better, and the normal preparation of the steel frame 10 will not be affected.

[0085] In some or certain embodiments, the adjusting member 3 may also be supported by a plurality of telescopic mechanisms 4, and the adjusting member 3 may also be spaced apart from the positioning frame 2 and located between the positioning frame 2 and the supporting member 1. The upper chord 101 and the lower chord 103 may also be supported and subsequently manufactured.

[0086] In some or certain embodiments, the positioning frame 2 comprises:

[0087] The frame 22 is provided with a first supporting surface 21 .

[0088] The limiting portion 23 and the stopping portion 24 are both disposed on the frame 22 and protrude from the first supporting surface 21 . The limiting portion 23 , the stopping portion 24 and the first supporting surface 21 form a limiting groove 25 , which extends along the arrangement direction of the telescopic mechanism 4 .

[0089] The limiting portion 23, the stop portion 24 and the first supporting surface 21 form a limiting groove 25, which extends along the arrangement direction of the telescopic mechanism 4, so that the upper chord 101 or the lower chord 103 of the steel frame 10 can be set along the arrangement direction of the telescopic mechanism 4, which is convenient for controlling the straightness and also beneficial for controlling the position accuracy.

[0090] In some or certain embodiments, the limiting portion 23 may be block-shaped, the stopper portion 24 may be plate-shaped, the frame body 22 may include a main body portion 221 of the frame and a plate-shaped support portion 222 disposed on the main body portion 221, the first support surface 21 is disposed on the support portion 222, the support portion 222 may be located between the limiting portion 23 and the stopper portion 24, and contact the limiting portion 23. The support portion 222 may be used to place the upper chord 101 or the lower chord 103, and the support portion 222 cooperates with the limiting portion 23 to achieve relatively accurate positioning.

[0091] In some or certain embodiments, the support member 1 may be a support or a block-shaped or plate-shaped base, and the support member 1 may also be platform-shaped, and the positioning frame 2 and the telescopic mechanism 4 may both be arranged on the support member 1 .

[0093] S101: placing a plurality of upper components and a plurality of lower components on the first supporting surface and the second supporting surface respectively, and the plurality of upper components and the plurality of lower components are sequentially distributed along the arrangement direction of the telescopic mechanism.

[0094] S102: Connecting a plurality of middle components to a plurality of upper components and a plurality of lower components to form an integrated structure.

[0095] S103: Extending and retracting the telescopic mechanism to adjust the integrated structure to a preset deflection.

[0096] S104: Connecting every two adjacent upper components in the integrated structure to form an upper chord.

[0097] S105: Connecting every two adjacent lower members in the integrated structure to form a lower chord, thereby obtaining a steel frame.

[0098] The structure of the auxiliary tooling and its corresponding technical effects can be referred to above, and will not be repeated here. Before the upper chord and the lower chord of the steel frame are formed, multiple intermediate components are used to connect multiple upper components with multiple lower components to obtain an integrated structure. In the integrated structure, multiple upper components are not connected, and multiple lower components are not connected, but the integrated structure itself has a certain straightness. At this time, the telescopic mechanism is extended and retracted, and the deflection of the integrated structure is adjusted to be convex or concave to form a preset deflection. After the positions of the multiple upper components and the positions of the multiple lower components are determined, each adjacent two upper components in the integrated structure are finally connected to form an upper chord, and each adjacent two lower components in the integrated structure are connected to form a lower chord, so that a steel frame can be obtained. Before the preparation of the steel frame is completed, the integrated structure is provided with a preset deflection. After the steel frame is finally formed, the steel frame will be separated from the auxiliary tooling for use. The preset deflection set by the steel frame itself can offset the deflection of the steel frame due to its own center of gravity, so that the overall straightness of the steel frame can be better maintained during normal use, which is conducive to improving the reliability of the steel frame during use.

[0099] In some or certain embodiments, the weight of the upper member is greater than the weight of the lower member, and the second support surface is located between the first support surface and the support member. In step S101, placing a plurality of upper members and a plurality of lower members on the first support surface and the second support surface respectively may include:

[0100] A plurality of upper components are placed on the second supporting surface.

[0101] A plurality of lower components are placed on the first supporting surface.

[0102] When the support member is placed on the ground, the first support surface is higher than the second support surface, and the second support surface is higher than the support member. The lower component to which the weight is transferred is placed on the second support surface, and the upper component with smaller weight is placed on the first support surface. This can ensure the stability of the center of gravity of the auxiliary tooling, facilitate the manufacture of the steel frame, and reduce the possibility of tipping.

[0103] It should be noted that the multiple upper components on the second support surface are not shown in the figure. In some or certain embodiments of the present application, the multiple lower components may be multiple sections of C-shaped steel, and the multiple upper components may be multiple sections of H-shaped steel, all of which are placed in sequence along the arrangement direction of the telescopic mechanism.

[0104] Placing a plurality of upper components on the second supporting surface in step S101 may include:

[0105] Multiple upper components are placed on the second support surface in sequence along at least two telescopic mechanisms arranged side by side. The telescopic mechanisms can be adjusted to be telescopic, and the weight of the upper components or the lower components is added to naturally change the deflection of the second support surface. Multiple lower components are placed on the first support surface in the same manner, so it will not be described in detail.

[0106] It should be noted that, for example, the auxiliary tooling includes two telescopic mechanisms, and the steel frame is located between the two telescopic mechanisms. When the steel frame is placed between the two telescopic mechanisms, the adjusting member will be pressed down to form a concave deflection. The auxiliary tooling may also include multiple telescopic mechanisms arranged side by side. When the two ends and the middle of the steel frame correspond to a telescopic mechanism respectively, the telescopic mechanism corresponding to the middle part can make the steel frame convex or concave, and the deflection adjustment of the integrated structure is similar.

[0107] In some or certain embodiments, if the weight of the lower member of the steel frame is greater than that of the upper member of the steel frame, the lower member of the steel frame may be placed on the second support surface, and the upper member of the steel frame may be placed on the first support surface. This may be adjusted according to the structure of the steel frame.

[0108] In step S101 of some or certain embodiments, a plurality of upper components or lower components may be placed on the first supporting surface first.

[0109] In step S102 of some or certain embodiments, multiple intermediate members may be passed through the positioning frame to connect multiple upper members and lower members according to the structure of the steel frame. The intermediate members may be connecting pipes or connecting beams.

[0110] In step S103 of some or certain embodiments, “making the telescopic mechanism telescope to adjust the integrated structure to a preset deflection” includes:

[0111] The telescopic mechanism is telescoped to make the integrated structure concave toward the support member to a preset deflection.

[0112] The upper member with heavier weight is placed on the second supporting surface, and the lower member with lighter weight is placed on the first supporting surface. The state of the steel frame is upside down from the state when it is used. Therefore, when setting the deflection, the second supporting surface on the adjusting member can be sunken to the preset deflection, and the integrated structure supported on the second supporting surface will also be sunken toward the supporting member to the preset deflection. The integrated structure achieves the preset deflection in this way. After the steel frame is prepared, the steel frame itself will have a concave preset deflection. However, when the steel frame is separated from the auxiliary tooling and put into use, it needs to be flipped so that the steel frame is in a state where the upper chord is higher than the lower chord. If the part between the two ends of the steel frame moves downward due to gravity, the convex deflection of the upper chord can be offset, so that the straightness of the steel frame is guaranteed during normal use, which is beneficial to the reliability of the steel frame.

[0113] It should be noted that, since the steel frame usually has a large volume and weight, the upper chord and the lower chord of the steel frame usually also have a large weight. Therefore, when the upper chord of the steel frame is placed on the second supporting surface, the upper chord of the steel frame and the second supporting surface are in a close contact state, and the deflection change of the second supporting surface is equal to the deflection change of the integrated structure.

[0114] For ease of understanding, here is provided Figure 5 , Figure 5 A schematic diagram of adjusting the deflection of a second supporting surface in some embodiments or certain embodiments of the present application is shown. Figure 5 The second supporting surface and the horizontal plane are shown in FIG. , and the second supporting surface is concave.

[0115] In some or certain embodiments, placing a plurality of lower members on the first support surface may include:

[0116] Along the arrangement direction of the telescopic mechanism, a plurality of upper components are placed in sequence on the first supporting surface, and there is a millimeter-level spacing between two adjacent upper components.

[0117] In the inverted preparation of the steel frame, since the concave deflection will squeeze the positions between multiple upper components, before connecting the upper components and the lower components, a millimeter-level spacing is made between two adjacent upper components. After adjusting the deflection, the positions between the upper components are more accurate and easy to connect, so as to obtain a steel frame with better quality.

[0118] It should be noted that the millimeter-level spacing is a spacing of 0 to 10 mm. In some or certain embodiments, the spacing between two adjacent upper components may be about 5 mm.

[0119] In step S103 of some or certain embodiments, if the upper member of the steel frame is placed on the first support surface and the lower member is placed on the second support surface, the telescopic mechanism can also be telescoped so that the integrated structure protrudes away from the support member to a preset deflection. In this case, the steel frame does not need to be inverted when in use, so after the steel frame is separated, the preset deflection of the steel frame can offset the deflection of the steel frame caused by gravity.

[0120] It should be noted that the deflection value corresponding to the preset deflection in step S103 may be the deflection value corresponding to the deflection of the steel frame caused by gravity in a natural state. The integrated structure is provided with a preset deflection to offset the deflection of the steel frame caused by its own weight. The deflection data may be obtained by measuring the distance between the multi-point second support surface and, for example, a horizontal reference plane in the arrangement direction of the telescopic mechanism using a measuring instrument such as a measuring ruler.

[0121] In some or certain embodiments, in step S104 and step S105, every two adjacent upper members may be welded or connected, or every two adjacent lower members may be welded or connected to obtain an upper chord or a lower chord.

[0122] It should be noted that the order of step S104 and step S105 can also be replaced according to the preparation requirements of the steel frame, and the lower chord can be formed first and then the upper chord can be formed to obtain the steel frame.
