DETAILED DESCRIPTION

[0051] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0052] Reference Figure 1-29 A building steel structure support device comprises a column 1, and a longitudinal beam 2 and a transverse beam 3 horizontally arranged at the top of the column 1; wherein the column 1, the longitudinal beam 2 and the transverse beam 3 are I-beams, and the lengths thereof are reasonably selected and arranged according to the actual building area; at the same time, four beams are arranged at the top of the column 1 at the middle position, and two or three beams are arranged at the top of the column 1 at the edge position; Figure 1 As shown, the longitudinal beam 2, the transverse beam 3 and the column 1 form an overall building steel structure support.

[0053] In some embodiments, a top connector is provided at the top of the column 1, and the ends of the longitudinal beam 2 and the cross beam 3 are positioned and fixed after contacting the top connector; by setting the top connector, the connection accuracy can be controlled and a larger contact and connection area can be obtained.

[0054] The top connecting member comprises a top seat 7 and a positioning cylinder 8 assembled and connected with the top seat 7 .

[0055] Among them, the top seat 7 is fixedly connected to the top of the column 1 to provide a precise plane support foundation; the positioning cylinder 8 is a quadrilateral cylinder or an octagonal cylinder, corresponding to the ends of the longitudinal beam 2 and the cross beam 3, limiting their movement and achieving precise positioning.

[0056] It should be noted that the corresponding surface area between the positioning tube 8 and the beam end should not be less than the area of ​​the beam end surface, so as to form sufficient top contact and welding positions to ensure the reliability and stability of the support system.

[0057] In the removable configuration of the top connector: A downwardly recessed sinking plate 81 is provided inside the positioning tube 8, a center hole 82 is opened on the sinking plate 81 and a high-strength bolt 83 is passed through it; correspondingly, an internally threaded sleeve 71 is fixedly provided at the center position of the top surface of the top seat 7; after the high-strength bolt 83 penetrates the center hole 82, it is threadedly connected with the internally threaded sleeve 71 to fix the positioning tube 8 and the top seat 7 as a whole.

[0058] It should be noted that the downward recessed depth of the sinking plate 81 is used to accommodate the head of the high-strength bolt 83 so that it does not protrude upward; at the same time, the required height of the high-strength bolt 83 and the internal threaded sleeve 71 can be shortened.

[0059] Furthermore, a short sleeve is provided at the lower end of the center hole 82 and is sleeved on the outside of the internal threaded sleeve 71, so as to quickly locate and install the positioning tube 8, and increase the stability and strength of the connection state; at the same time, it is also convenient to rotate and adjust the positioning tube 8.

[0060] Furthermore, a reinforcing triangular plate is disposed around the outer side of the internal threaded sleeve 71 .

[0061] It is understandable that the height of the reinforcing triangle plate should be smaller than the overall height of the internal threaded sleeve 71 so as not to affect the installation of the short sleeve below the sinking plate 81 .

[0062] Preferably, the diameter of the center hole 82 is larger than the outer diameter of the screw of the high-strength bolt 83 to avoid rigid contact and damage between the two.

[0063] Furthermore, a boss 84 cooperating with the center hole 82 is provided below the bolt head of the high-strength bolt 83 ; the height of the boss 84 is smaller than the thickness of the center hole 82 , further avoiding contact between the center hole 82 and the threaded portion of the high-strength bolt 83 .

[0064] In some embodiments, an extended pressing plate 85 is provided on the outer side of the positioning cylinder 8 corresponding to the upper position of the longitudinal beam 2 and the transverse beam 3 .

[0065] like Figure 7 As shown, four extension plates 85 are provided corresponding to the four beams; and in the installed state, the extension plates 85 press on the upper end of the beam body, exerting downward pressure thereon, thereby further strengthening the fixation.

[0066] It is understandable that the positioning tube 8 at the edge position can reduce the number of extended pressure plates 85 according to actual needs; it only needs to correspond to the beam body.

[0067] In some embodiments, two strip-shaped slots 86 are provided on the extended pressure plate 85 along its length direction; at the same time, beam end positioning holes 87 are respectively provided at the ends of the longitudinal beam 2 and the transverse beam 3 corresponding to the two end positions and the middle position of the strip-shaped slots 86; in addition, a top seat through hole 88 is provided on the top seat 7 corresponding to the beam end positioning holes 87.

[0068] It should be noted that the positions of the strip notches 86 , the beam end positioning holes 87 , and the top seat through holes 88 should avoid the waist plates of the longitudinal beams 2 and the transverse beams 3 .

[0069] It should be noted that the two beam end positioning holes 87 at both ends are set close to the end of the strip slot 86 and do not need to overlap with the end of the strip slot 86 to obtain a larger adjustment range; that is, the distance between the two beam end positioning holes 87 at both ends of a strip slot 86 is smaller than the length of the strip slot 86.

[0070] in: During installation, after the longitudinal beam 2 and the transverse beam 3 are placed, bolts are first inserted through the beam end positioning holes 87 corresponding to the middle positions and penetrate the strip notches 86 and the beam end positioning holes 87 for initial positioning; at this time, the longitudinal beam 2 and the transverse beam 3 can also be moved and adjusted in a small range within the range of the strip notches 86.

[0071] After the final precise positioning, three sets of bolts are inserted through the strip notch 86, the beam end positioning hole 87, and the top seat through hole 88 to lock it; then, welding is performed (welding is optional and not necessary).

[0072] In some embodiments, the top seat 7 includes a quadrilateral or octagonal top plate 72, and a first positioning plate 73 and a second positioning plate 74 extending downward and respectively fitting the wing plate and waist plate of the column 1; the first positioning plate 73 and the second positioning plate 74 are clamped at the top of the column 1 to achieve a high-reliability connection.

[0073] Furthermore, triangular plates 75 are provided at both ends of the outer sides of the first positioning plate 73 and the second positioning plate 74 to further improve the bearing performance and reliability.

[0074] It is understandable that, during installation, the first positioning plate 73 and the second positioning plate 74 are attached to the column 1 and the top seat 7 is adjusted, and then they are welded and fixed.

[0075] Furthermore, the inner vertical edges of the first positioning plate 73 and the second positioning plate 74 are configured as rounded corners; thereby, a larger contact surface can be obtained during welding, forming a more reliable connection state.

[0076] Preferably, a vertical slot is formed on the second positioning plate 74, and a through bolt hole is formed on the waist plate of the column 1 correspondingly within the slot to form an adjustable temporary fixation during installation.

[0077] in: When installing the top seat 7, firstly penetrate the bolts through the slots and the bolt holes for temporary fixation; after the top seat 7 is accurately leveled, tighten the bolts, and weld the inner sides of the first positioning plate 73 and the second positioning plate 74 to the column 1 for fixation.

[0078] In some embodiments, a middle connecting seat 4 is provided in the middle upper part of the column 1 , and the middle connecting seat 4 is connected to the diagonal rod 5 by bolt assembly, and the top end of the diagonal rod 5 is connected to the lower end of the longitudinal beam 2 and the cross beam 3 .

[0079] Thus, by cooperating with the installed middle connecting seat 4 and the diagonal rod 5, a reinforced support system is formed to constitute a relatively complete steel structure support (structures such as trusses may be optionally provided).

[0080] The cross beam 3 is located in the opening direction of the I-beam of the column 1; correspondingly, the longitudinal beam 2 and the cross beam 3 are arranged vertically on the horizontal plane.

[0081] Correspondingly, two groups of ear plates 31 are symmetrically arranged at the lower end of the cross beam 3 , which are used to pass bolts and connect with the top end of the diagonal rod 5 .

[0082] It can be understood that the two groups of ear plates 31 correspond to the two inclined rods 5 respectively; the lower ends of the two inclined rods 5 are respectively connected to the middle connecting seats 4 of the two lower columns 1.

[0083] Specifically, Figures 23 to 25 As shown; the connecting seat 4 is a flat C-shaped structure with its opening facing outward, clamping the lower end of the connecting diagonal rod 5, and having holes through which bolts are passed to connect with the diagonal rod 5.

[0084] At the same time, a strip slide groove 11 is vertically opened on the wing plate of the column 1; correspondingly, slide plates 41 are respectively extended forward and backward at the front and rear ends of the central connecting seat 4, and the slide plate 41 penetrates to the outside of the strip slide groove 11 to realize vertical up and down adjustment of the central connecting seat 4.

[0085] It is understandable that the slide plate 41 is welded to the middle connecting seat 4 or produced by integral casting; the height of the slide plate 41 should be smaller than the length of the strip slide groove 11; the length of the strip slide groove 11 is formed according to the adjustment range required by the actual environment.

[0086] Therefore, when in use, the two ends of the oblique rod 5 are respectively connected to the ear plate 31 and the middle connecting seat 4 by bolts; at this time, the middle connecting seat 4 is movable; after the middle connecting seat 4 is slid up and down to the most appropriate position, it is welded and fixed.

[0087] It should be noted that different supporting forces on the cross beam 3 are formed by moving the middle connecting seat 4 ; that is, the middle connecting seat 4 moves upward to increase the supporting force of the diagonal rod 5 on the cross beam 3 .

[0088] During welding, the slide plate 41 is welded to the inner side of the wing plate of the column 1 .

[0089] Furthermore, the inner end of the middle connecting seat 4 is arranged to contact the waist plate, and the two are welded to form a more stable welding state.

[0090] Preferably, a hole is formed on the slide plate 41 close to the wing plate of the column 1 and a pin rod 42 is passed through the hole; the outer surface of the pin rod 42 contacts the wing plate of the column 1 to limit the forward and backward movement of the middle connecting seat 4.

[0091] Preferably, two pins 42 are provided on each side.

[0092] In some embodiments, a bolt hole is opened near the end of the slide plate 41, and bolts are passed through to assemble the diagonal rods 5 corresponding to the longitudinal beam 2; thus, the adjustable middle connecting seat 4 can simultaneously connect the diagonal rods 5 corresponding to the longitudinal beam 2 and the cross beam 3.

[0093] Correspondingly, a slide seat 21 is slidably provided on the lower wing plate of the longitudinal beam 2, and the top end of the diagonal rod 5 is assembled and connected with the slide seat 21 through bolts.

[0094] It is understandable that the middle connecting seat 4 can only be fixed after it is adjusted according to the diagonal rod 5 of the cross beam 3; therefore, the installation sequence of the diagonal rod 5 needs to be controlled; in combination with the sliding seat 21 on the longitudinal beam 2 set in this application, no matter how the middle connecting seat 4 is adjusted, it will not affect the assembly of the diagonal rod 5 of the longitudinal beam 2.

[0095] It should be noted that the slide 21 forms different supporting forces through the sliding position; that is, the closer the slide 21 is to the beam end that is closer to itself, the greater the upward supporting force formed; when the supporting structure is specifically assembled, it is adjusted according to the actual situation.

[0096] In some embodiments, the slide 21 includes: a base plate attached to the lower surface of the longitudinal beam 2, a side top plate integrally arranged on both sides of the base plate and bent upward to attach to the upper surface of the lower wing plate of the longitudinal beam 2, and an ear plate fixedly arranged under the base plate.

[0097] Through the coordinated shape, stability during movement is ensured.

[0098] It can be understood that after being moved into position, the slide seat 21 and the longitudinal beam 2 are welded into one body.

[0099] Furthermore, a threaded pressing screw is provided below the base plate and / or above the side top plate to temporarily tighten and limit the position after being in place, making subsequent welding operations more convenient.

[0100] In some embodiments, it also includes: a base 6 cast in the concrete foundation; accordingly, the bottom end of the column 1 is connected to the base.

[0101] Specifically, the base 6 includes a flat bottom plate 61 , a side baffle 62 inserted through the flat bottom plate 61 from bottom to top, and a steel bar hook 63 fixedly connected to the bottom of the side baffle 62 .

[0102] Correspondingly, a strip opening is provided on the flat bottom plate 61 corresponding to the outer sides of the wing plate and waist plate of the column 1 ; the side baffle plate 62 is inserted through the strip opening, and its inner side surface is in contact with the wing plate and waist plate of the column 1 .

[0103] Before installation, the base 6 is embedded in the concrete with high precision, and the flat bottom plate 61 and the side baffle 62 are exposed; during installation, the column 1 is inserted into the space formed by the side baffle 62, and after accurate positioning, it is welded and fixed.

[0104] It should be noted that a certain movable space can be formed between the side baffle 62 and the wing plate and waist plate of the column 1 to facilitate adjustment and positioning.

[0105] Preferably, the inner vertical edge and the top edge of the side baffle 62 are configured as rounded corners; thereby, a larger contact surface can be obtained during welding, forming a more reliable connection state.

[0106] In some embodiments, vertical slots are provided on the side baffles 62 corresponding to the sides of the waist plate of the column 1 ; and through bolt holes are provided on the waist plate of the column 1 corresponding to the slots.

[0107] in: On the installation column 1, first penetrate the bolts through the slots and the bolt holes for temporary fixation; after the column 1 is accurately leveled, tighten the bolts and weld the inner side of the side baffle 62 to the column 1; at the same time, weld the lower side of the column 1 to the flat bottom plate 61, making the entire operation process safer and more controllable.

[0108] In some embodiments, a stopper larger than the strip opening of the flat bottom plate 61 is provided at the lower end of the side baffle plate 62, so as to have stronger anti-pullout performance.

[0109] In some embodiments, the steel bar hook 63 includes: two vertical side edges that are integrally arranged, a top horizontal edge, and a curved hook at the lower end of the vertical side edges.

[0110] Among them, at least two steel bar hooks 63 are arranged in a crisscross pattern; the top ends of the steel bar hooks 63 form a cross structure and are connected to the lower ends of the side baffles 62 by welding.

[0111] Furthermore, it also includes: a steel bar hook 63 directly welded to the lower end of the flat bottom plate 61.

[0112] Furthermore, the vertical length of the steel bar hook 63 is set according to the steel bars in the concrete foundation so that it is hooked on the concrete steel bars and fixed by tying wire.

[0113] Preferably, a reinforcing steel bar ring is fixedly provided on the outer ring side of the steel bar hook 63; this can avoid large deformation of the steel bar hook 63 and improve the overall strength and bearing capacity of the steel bar hook 63.

[0114] When the present invention is used, the required sizes and positions of the columns 1, longitudinal beams 2 and cross beams 3 are pre-designed, and the base 6 is pre-buried; when installing, the columns are first installed and welded to the base 6; then, the top seat 7 is adjusted and welded to it, and the positioning cylinder 8 is installed, but not locked temporarily; the longitudinal beams 2 and cross beams 3 are installed, and connected and fixed to the positioning cylinder 8; finally, the diagonal rod 5 is installed, and adjusted and welded to it.
