Rather, use of the term "exemplary" is intended to present relevant concepts in a concrete fashion.

Compared with the traditional concrete building, the steel plate or the section steel replaces reinforced concrete, so that the steel structure building has higher strength and better shock resistance. Since the members of the steel plate or section steel can be prefabricated in a factory and installed on site, the construction period can be reduced. And, because the steel can be recycled, can reduce the construction waste, more green, therefore is used in industrial building and civil construction extensively.

In the existing building, a pull rod with high strength and small section is used between two adjacent layers of steel structure beams to bear the gravity load. Referring to fig. 1, fig. 1 is a front view illustrating a cross member and a drawbar connected by an ear plate according to the related art. When the pull rods 02 are arranged, two ear plates 03 are welded on the upper side and the lower side of a cross beam 01 (the cross beam 01 is generally made of I-steel and comprises two mutually parallel flange plates 011 and a web 012 for connecting the two flange plates), and the two pull rods 02 on the upper side and the lower side of the cross beam 01 are respectively connected with the two ear plates 03 through pin shafts 04, so that the fixed connection between the pull rods 02 and the cross beam 01 is realized.

Since the load borne by the tie rods 02 is large, the size of the lug plates 03 is generally increased in order to reinforce the connection strength between the tie rods 02 and the cross member 01. Referring to fig. 2, fig. 2 is a side view of the structure shown in fig. 1. Illustratively, the width of the ear plate 03 can be increased along a direction perpendicular to the web 012, so that a larger welding area can be provided between the ear plate 03 and the cross beam 01, and the connection strength between the ear plate 03 and the cross beam 01 can be improved; correspondingly, along the direction perpendicular to the flange plate 011, the height of the lug plate 03 needs to be increased, so that the pull rod 02 and the lug plate 03 can be connected through the pin shaft 04 with a larger diameter, and the connection strength of the pull rod 02 and the lug plate 03 is increased. Therefore, the connection strength of the tie rods 02 and the cross beam 01 is improved.

Further, with continued reference to fig. 2, since the width direction of the ear plate 03 is perpendicular to the web 012, in order to avoid deformation of both side edges of the flange plate 011 caused by the force of the ear plate 03, thereby causing deformation of the cross beam 01. The stiffening plate 05 is required to be arranged between the upper flange plate 011 and the lower flange plate 011 of the cross beam 01, the stiffening plate 05 is coplanar with the upper ear plate 03 and the lower ear plate 03, and the transmission path of the acting force between the upper pull rod 02 and the lower pull rod 02 is increased while the structure of the cross beam 01 is reinforced.

Due to the fact that the ear plates 03 are large in size, the ear plates 03 arranged on the upper side and the lower side of the cross beam 01 in a protruding mode occupy the use space in the building structure, and therefore the attractiveness of the building structure is reduced. Moreover, the two pull rods 02 on the upper side and the lower side of the cross beam 01 transmit the acting force through the ear plates 03, the cross beam 01 and the stiffening plate 05, so that the transmission path is indirect and unclear, and meanwhile, the cross beam 01 serves as a main node of the acting force transmission path, so that the upper side and the lower side of the cross beam 01 need to additionally bear the acting force of the two pull rods 02, which can lead to poor stress performance of the structure.

In order to solve the above problem, in one aspect, the present application provides a connection node of a tie bar and a cross beam. Referring to fig. 3, fig. 3 is a front view of a tie rod and beam connection node 100 according to an embodiment of the present disclosure. The tie-to-beam connection node 100 (hereinafter referred to simply as the connection node 100) includes a tie, a beam, and a tie-to-beam connection structure 10. Along the first straight line direction, the upper end and the lower end of a connecting structure 10 (hereinafter referred to as the connecting structure 10) of the pull rod and the cross beam are respectively fixedly connected with two pull rods 20 which are arranged at intervals; along the second straight line direction, the left and right sides of the connecting structure 10 are respectively fixedly connected with two cross beams 30 arranged at intervals. In this way, two tie rods 20 and a cross beam 30 which are arranged at intervals are connected through the connecting structure 10, so that the fixed connection of the tie rods 20 and the cross beam 30 is realized.

It should be noted that the first linear direction may be an up-down direction in fig. 3, that is, the lengths of the two pull rods 20 extend along the first linear direction; the second linear direction may be the left-right direction in fig. 3, i.e., the lengths of both beams 30 extend in the second linear direction; at this time, the first linear direction is perpendicular to the second linear direction. The first linear direction may intersect with the second linear direction, and is not particularly limited herein.

The application also provides a connecting structure 10 of the pull rod and the cross beam. Referring to fig. 4, fig. 4 is a top view of the tie rod to beam connection node 100 shown in fig. 3. The connecting structure 10 includes a first connecting member 11 and two second connecting members 12.

Referring to fig. 3, two tie rods 20 are fixed to upper and lower ends of the first connecting member 11, respectively, in the first linear direction, for bearing the gravity load.

Along the second linear direction, the two second connecting members 12 are fixed to the left and right sides of the first connecting member 11, respectively. Since the connecting structure 10 is located between the two cross beams, the left end of the second connecting member 12 located on the left side is connected to one of the cross beams 30, and the right end of the second connecting member 12 located on the right side is connected to the other cross beam 30. The two second connecting members 12 are arranged to facilitate the fixing of the first connecting member 11 between the two cross members 30.

Because the first connecting piece 11 is clamped and fixed between the two second connecting pieces 12, that is, the two second connecting pieces 12 are arranged at two sides of the first connecting piece 11 at intervals and are fixedly connected with the first connecting piece 11. In order to achieve a continuous installation effect between two spaced second connecting members 12, as shown in fig. 4, the connecting structure 10 further includes a third connecting member 13, and two ends of the third connecting member 13 are respectively connected and fixed to one ends of the two second connecting members 12 close to the first connecting member 12. That is, the left end of each third connecting member 13 is fixedly connected with the right end of the left second connecting member 12, and the right end of each third connecting member 13 is fixedly connected with the left end of the right second connecting member 12. In this way, the connection strength between the two second connecting members 12 arranged at intervals is improved, and the two second connecting members 12 arranged at intervals can be regarded as an integral structure through the connection fixation of the third connecting member 13.

Therefore, the connecting structure 10 of the tie rod and the beam and the connecting node 100 thereof provided by the embodiment of the application enable the force between the two tie rods 20 to be directly transmitted and the transmission of the force to be clear by fixing the two tie rods 20 at the upper end and the lower end of the first connecting piece 11 respectively, thereby improving the bearing capacity of the building structure using the connecting structure 10. Moreover, because the two second connecting pieces 12 are fixed on the two opposite sides of the first connecting piece 11, and the two opposite ends of the two second connecting pieces 12 are respectively and fixedly connected with the two cross beams 30, that is, along the second linear direction, the connecting structure 10 can be fixed between the two cross beams 30, compared with an ear plate structure, the concealed arrangement of the connecting structure 10 is facilitated, the occupation of the use space in the building structure is avoided, and the beauty of the building structure is not affected. In addition, the third connecting member 13 is arranged so that the two second connecting members 12 arranged at intervals can be regarded as an integral structure, and the connecting strength of the two second connecting members 12 arranged at intervals is further increased, so that the integral strength of the connecting structure 10 is improved.

It should be noted that, since the connecting structure 10 is located between the two cross beams 30, in the first linear direction (i.e. the up-down direction in fig. 3), the upper and lower ends of the connecting structure 10 (especially the first connecting member 11) may be arranged to be flush with the cross beams 30 or slightly protrude from the surface of the cross beams 30, so as to facilitate the connection of the pull rod 20. Therefore, the concealed arrangement of the connecting structure 10 is realized, the occupation of the use space in the building structure is avoided, and the attractiveness of the building structure is not influenced.

The connection of the draw bar 20 to the first connecting member 11 will be explained. As shown in fig. 3, the first connecting member 11 extends along a first straight line, and the upper and lower ends of the first connecting member 11 are respectively provided with a connecting hole (not shown in the figure), so that the upper and lower pull rods 20 can be aligned and installed by the connecting holes.

When the pull rod and the first connecting piece are fixedly connected, for example, an internal thread is arranged in the connecting hole, and correspondingly, an external thread matched with the internal thread is arranged at the end part of the pull rod 20 used for being connected with the connecting hole. So, when installing first connecting piece 11 and pull rod 20, pull rod 20 can be adorned into corresponding the connecting hole of end soon to realize the screw thread fixed connection with first connecting piece 11, and then realize the fixed connection with connection structure 10, the field installation is more convenient.

In addition, the tie rod 20 may be directly welded to the first connecting member 11, and the tie rod 20 may be similarly connected and fixed to the first connecting member 11.

In some embodiments, the first connecting member 11 is a connecting sleeve, and the inner cavity of the connecting sleeve forms the two connecting holes, so that the structure is simple. For example, as shown in fig. 3, the inner cavity of the connecting sleeve penetrates in the up-down direction, the upper half section of the connecting sleeve may form one connecting hole, and the lower half section of the connecting sleeve may form another connecting hole, that is, two connecting holes of the first connecting member 11 are communicated. At this time, the central axes of the two coupling holes are collinear, so that the central axes of the two tie rods 20 installed in the two coupling holes are also collinear, facilitating direct transmission of the bearing force between the upper and lower tie rods.

Of course, in other embodiments, the two connection holes of the first connection member 11 may be separately disposed and not connected, and may also be used.

The structure of the second connecting member 12, the structure of the cross member 30, and the fixed connection of the second connecting member 12 to the first connecting member 11 and the cross member 30 will be exemplified below.

In some embodiments, the cross-section of the cross-beam 30 perpendicular to the second linear direction may be an i-shaped, C-shaped (channel profile) or rectangular (rectangular profile) profile. In order to facilitate the connection and fixation of the second connecting piece 12 and the cross beam 30, the cross section of the second connecting piece 12 perpendicular to the second straight line direction is also an i-shaped, C-shaped or rectangular structural section similar to that of the cross beam 30.

Example 1

The cross beam 30 and the second connecting member 12 are both of i-shaped structures for illustration:

referring to fig. 5, fig. 5 is a side view of the connection structure 10 of fig. 3. The second connecting member 12 is also an i-shaped structure, and includes two first flange plates 121 parallel to each other and a first web 122 connecting the two first flange plates 121, and the upper and lower edges of the first web 122 are respectively fixed to the middle positions of the two first flange plates 121.

Correspondingly, as shown in fig. 3, the cross beam 30 is an i-shaped structure, and includes two second flanges 31 parallel to each other and a second web 32 connecting the two second flanges 31, and the upper and lower edges of the second web 32 are respectively fixed to the middle positions of the two second flanges 31.

Thus, referring to FIG. 6, FIG. 6 is a cross-sectional view taken at A-A of FIG. 3. One end of the first web 122 is fixedly connected to the first connecting member 11, typically welded, to fix the second connecting member 12 to the first connecting member 11. And the other end of the first web 122, which is far away from the first connecting member 11, is fixedly connected with the cross beam 30.

Illustratively, the connection node 100 further includes a fourth connection member 40, the fourth connection member 40 including a fixing plate 41, a first fastening member 42, and a second fastening member 43. The fixing plate 41 is overlapped with the second web plate and the first web plate 32, respectively, and a first through hole (not shown in the figure) penetrating through the fixing plate 41 and the second web plate and a second through hole (not shown in the figure) penetrating through the fixing plate 41 and the first web plate 122 are respectively opened in the two overlapped areas. Passing a first fastener 42 through the first through hole to fixedly connect the fixing plate 41 and the second web 32; and a second fastening member 43 is inserted through the second through hole to fixedly connect the fixing plate 41 and the first web 122. In this way, by the arrangement of the fourth connecting member 40, the second web 32 can be fixedly connected with the first web 122, so that the connecting structure 10 can be fixed between the two cross beams 30.

The first fastening member 42 and the second fastening member 43 include bolts and nuts, or rivets, and both can realize the fixed connection between the fixing plate 41 and the second web 32, and between the fixing plate 41 and the first web 122, and the installation is convenient. In addition, the fixing plate 41 and the second web 32, and the fixing plate 41 and the first web 122 can be detachably connected through bolts and nuts, so that the fixing plate is convenient to reuse.

It should be noted that each fourth connecting element 40 may include one fixing plate 41, or may include two fixing plates 41. As shown in fig. 6, two fixing plates 41 are fixed on the front and rear sides of the second web 32 and the first web 122, respectively, and the clamping area of the fixing plates 41 on the second web 32 and the first web 122 is increased and the fixing strength of the fourth connecting member 40 on the connecting structure 10 and the cross beam 30 is improved by the arrangement of the two fixing plates 41.

In addition, when there is one fixing plate 41, the fixing plate 41 may be fixed to the front side or the rear side of the second web 32 and the first web 122, and the fixed connection between the second web 32 and the first web 122 may be achieved, which is not limited herein.

In some embodiments, the second connecting member 12 and the cross member 30 may also be welded and fixed during the process of fixedly connecting the cross member 30 and the connecting structure 10. In the case where the cross member 30 and the second connector 12 are both of an i-shaped configuration. As shown in fig. 6, the first flange plate 121 and the second flange plate 3 are welded and fixed in the left-right direction to fixedly connect the cross beam 30 and the connecting structure 10, i.e., the first flange plate 121 and the second flange plate 31 are fixedly connected by a weld (black structure in the figure). In addition, the first web 122 and the corresponding second web 32 may also be fixed by welding to increase the connection strength between the cross beam 30 and the connecting structure 10.

It should be noted that, in the case that the connection node 100 further includes the fourth connection member 40, the fixing plate 41 may prevent the welding of the welding seam between the first web 122 and the second web 32. Therefore, the fourth connecting member 40 can ensure the connection strength between the cross beam 30 and the connecting structure 10 without welding the second web 32 and the first web 122.

Moreover, in the process of fixedly connecting the cross beam 30 and the connecting structure 10 through the fourth connecting member 40, the first flange plate 121 of the connecting structure 10 and the second flange plate 31 of the cross beam 30 are generally aligned, and after the fixing is completed, the relative positions of the second flange plate 31 and the first flange plate 121 are kept fixed. At this time, it is very convenient to weld the second flange plate 31 and the first flange plate 121. Therefore, it is possible to continue to weld-fix the second flange plate 31 and the first flange plate 121 after the fixing of the fourth connection member 40 is completed, thereby improving the connection strength of the cross beam 30 and the connection structure 10.

In some embodiments, the third connecting member 13 includes a through-flange plate for fixedly connecting two spaced second connecting members 12. Illustratively, the second connecting member 12 has two oppositely disposed plate surfaces, i.e., two parallel first flange plates 121, as shown in fig. 4, two ends of the through flange plate are respectively connected to the two first flange plates 121 on the same side of the two second connecting members 12, and at least part of the plate surfaces of the through flange plate are respectively overlapped with the two first flange plates 121 on the upper side or the lower side. The first flange plates 121 of the two second connecting pieces 12 are fixedly connected through the flange through plate, so that the installation is convenient and rapid.

The third connecting member 13 (i.e., the flange through plate) and the second connecting member may be welded and fixed to the first flange plate, and as shown in fig. 4, the periphery of each flange through plate is welded and fixed to the first flange plate 121 by a black-structured welding seam. Since the connecting structure 10 is usually a prefabricated member produced in a factory, the welding-fixed connecting method does not need an additional fixed connecting structure, and the structure is simple and the installation is convenient.

In addition, the third connecting member 13 may further include a third fastening member (not shown), and an overlapping region of the flange through plate and each of the first flange plates 121 is provided with a third through hole penetrating through the flange through plate and the first flange plate 121, and the third fastening member passes through the third through hole to fixedly connect the flange through plate and the first flange plate 121, so that the third connecting member 13 is fixedly connected to the two second connecting members 12. The third fastening piece can be a fastening structure of a bolt and a nut, so that the first flange plate and the flange through plate can be detachably connected; the third fastener may also be a rivet fastener, which is not limited herein.

Illustratively, as shown in fig. 5, the third connecting member 13 includes two sets of through-flange plates, one set of through-flange plates being located on the upper sides of the upper two first flange plates 121, and the other set of through-flange plates being located on the lower sides of the lower two first flange plates 121. Because the upper and lower both ends of first connecting piece 11 all bulge in second connecting piece 12 and set up, consequently, two edges of a wing in every group link up the board interval and set up in the front and back both sides of first connecting piece 11. Therefore, the two second connecting pieces 12 are connected through the four flange through plates distributed at intervals, so that the connecting strength between the two second connecting pieces is improved, and the uniform distribution of the acting force of the two second connecting pieces is facilitated.

The number of the through plates of each group of flanges can also be one, three or four, and is not limited herein.

Example two

The cross beam 30 and the second connecting member 12 are rectangular in structure for illustration:

referring to fig. 7, fig. 7 is a side view of the second connector 12 with the connection structure 10 comprising a rectangular profile. The two first flange plates 121 are arranged at intervals up and down and connected with the two first reinforcing plates 123 arranged at intervals left and right to form a rectangular profile; i.e. the two first stiffening webs 123 are likewise parallel to each other.

In order to facilitate the welding and fixing of the first connecting member 11, a partition plate is further required to be arranged between the two first reinforcing plates 123, so that the upper side and the lower side of the partition plate are respectively welded and fixed with the two first flange plates 121, and the second connecting member 12 is welded and fixed with the first connecting member 11 through the partition plate. When the second connecting member 12 is an i-shaped profile, as shown in fig. 7, two first reinforcing plates 123 may be directly disposed on the front and rear sides of the first web 122, respectively, so as to convert the i-shaped profile into a rectangular profile. In this case, the partition is the first web 122.

Correspondingly, the cross beam comprises two second reinforcing plates which are oppositely arranged and two second flange plates which are oppositely arranged. The two second flange plates are distributed up and down and form a cross beam with a rectangular structure with the two second reinforcing plates distributed at intervals front and back.

In this way, when fixedly connecting the cross beam and the second connecting member, the two second reinforcing plates of the cross beam and the two second reinforcing plates of the second connecting member can be aligned, and the two second flange plates and the two first flange plates can be aligned as well.

The first reinforcing plate and the corresponding second reinforcing plate may then be fixedly connected directly by a welding process, or the first flange plate and the corresponding second flange plate may be fixedly connected directly by a welding process.

In addition, the first reinforcing plate and the corresponding second reinforcing plate can also be fixedly connected through a fourth connecting piece, and the first flange plate and the corresponding second flange plate can also be fixedly connected through the fourth connecting piece. Wherein, because the crossbeam of rectangular structure and the medial surface of second connecting piece are confined, consequently, every fourth connecting piece only need set up a fixed plate in the lateral surface can to, fixed plate and crossbeam or second connecting piece pass through rivet riveting or welded fastening.

For example, when the connection strength between the two second connecting members is enhanced, the flange through plate of the third connecting member may be used for fixedly connecting the two first reinforcing plates or the first flange plates on the same side of the two second connecting members, so as to enhance the fixing strength of the two second flange plates. The overlapped area of the flange through plate and the first reinforcing plate or the first flange plate is fixed by a welding process or a rivet.

It should be noted that, for specific structures of the third connecting element and the fourth connecting element, reference may be made to a part of the corresponding schemes in example one, and details of this application are not described herein. In addition, in any embodiment, the arrangement positions of the third connecting piece and the fourth connecting piece can be flexibly selected, and only the third connecting piece and the fourth connecting piece need not to be mutually influenced.

Example three

The following description will be made by taking the cross beam and the second connecting member as both C-shaped structures (i.e. groove-shaped structures):

at this time, the beam is of a C-shaped structure and comprises two second flange plates parallel to each other and a second web connecting the two second flange plates. Different from the I-shaped structure, two opposite edges of the second web plate are respectively fixed on the same side edges of the two second flange plates.

Correspondingly, the second connecting piece is of a C-shaped structure and comprises two first flange plates which are parallel to each other and a first web plate which is connected with the two first flange plates, and two opposite edges of the first web plate are respectively fixed on the same side edges of the two first flange plates.

In this case, the arrangement scheme of the cross beam and the second connecting piece of the C-shaped structure is similar to that of the cross beam and the second connecting piece of the I-shaped structure. The first flange plate and the second flange plate are respectively positioned on the same side of the first web plate and the second web plate in the direction perpendicular to the first web plate. The position relationship between the welding structure between the first flange plate and the second flange plate and the third connecting member is adjusted only by corresponding adjustment, which is not repeated herein.

In some embodiments, the connecting structure 10 and the connecting node 100, particularly the cross beam 30 and the second connecting member 12, are made of i-steel, channel steel or rectangular steel, so that the steel cost is low while the structural strength of the steel structure is satisfied. The material for the connection structure 10 and the connection node 100 may be other metal, metal alloy, or polymer material, and only needs to be able to achieve the design strength of the steel structure building, which is not limited herein.
