A spliced ​​wooden beam string

Abstract

A spliced ​​wooden beam string belongs to the field of building technology. It includes a main beam, including multiple beam segments, the multiple beam segments forming an inverted arch structure that bulges in the direction away from the roof; a splicing piece, which is a metal piece, is arranged at the ends of adjacent beam segments and is fixedly connected to two adjacent beam segments respectively. The main beam of the present invention is set as an inverted arch structure that bulges in the direction away from the roof, so that the roof is recessed into the interior of the building. Compared with the prior art in which the spliced ​​wooden beam string is set as an arch structure that arches in the direction of the roof, the present invention reduces the building height; because the inverted arch structure causes the main beam to bear greater pressure, the beam segments of the main beam of the present invention are connected by splicing pieces made of metal material. Due to the strong rigidity and strength of metal material, the connection points of the beam segments will not be damaged or dislocated due to the main beam being set as an inverted arch structure that bears greater force, thereby ensuring the pressure bearing capacity of the main beam.

Description

Technical Field

[0001] The present invention relates to the technical field of buildings, and in particular to a spliced ​​wooden beam string. Background Art

[0002] The beam string structure is a hybrid structural system consisting of a rigid upper chord, flexible cables, and intermediate struts. Its structural composition is a new type of self-balancing system and also a large-span prestressed spatial structural system.

[0003] Because the beam string structure is a long-span spatial structural system, its upper chord is relatively long. To facilitate the production and transportation of the upper chord, current upper chords are typically constructed in multiple segments, which are then individually produced and transported. These segments are then spliced ​​together to form the upper chord for use. This beam string structure allows the beam to be configured as an arched structure, which arches toward the roof, effectively improving the aesthetics and strength of the roof. However, this arched structure, arching toward the roof, increases the roof height. In some environments with high building height requirements, the beam string structure with this arched structure cannot meet these requirements. However, when the beam string structure is configured as a reverse arched structure, arching away from the roof—known as a reverse arched structure—the connection points between adjacent beam segments are susceptible to damage and misalignment, requiring greater connection strength. Existing designs cannot meet these requirements, making the reverse arched structure unsuitable for use in long-span roofs. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that the multi-segment beam string structures are all arc-shaped structures arched toward the roof, resulting in a high building height, thereby providing a spliced ​​wooden beam string structure.

[0005] The present invention provides the following technical solutions:

[0006] A spliced ​​wooden beam string, comprising:

[0007] A main beam comprising a plurality of beam segments, wherein the plurality of beam segments form an inverted arch structure that bulges away from the roof;

[0008] The splicing piece is a metal piece, which is arranged at the ends of the adjacent beam sections and is fixedly connected to the two adjacent beam sections respectively.

[0009] Optionally, the main beam is made of wood.

[0010] Optionally, the spliced ​​timber beam string further comprises:

[0011] The support is provided with a second accommodating cavity for accommodating the beam section, and the end of the beam section is embedded in the second accommodating cavity.

[0012] Optionally, both the end surface and the length surface of the beam section abut against the corresponding cavity wall of the second accommodating cavity.

[0013] Optionally, the spliced ​​timber beam string further comprises:

[0014] Hidden cables are respectively connected to adjacent splicing pieces, and / or the hidden cables are respectively connected to adjacent supports and splicing pieces; and the hidden cables are embedded in the beam section.

[0015] Optionally, a side of the beam section away from the roof is provided with a receiving groove arranged along the length direction of the beam section;

[0016] The hidden cable is embedded in the accommodating groove.

[0017] Optionally, the support is a plate-shaped structure;

[0018] The support and the main beam are connected through reinforcing bars arranged in a vertical direction of the support.

[0019] Optionally, the spliced ​​timber beam string further comprises:

[0020] Cables are respectively connected to supports at both ends of the main beam;

[0021] A support rod has one end connected to the main beam and the other end connected to the cable to provide prestressing force to the main beam.

[0022] Optionally, the spliced ​​timber beam string further comprises:

[0023] The secondary beam is arranged in the radial direction of the main beam and is connected to the main beam. A plurality of the secondary beams are arranged along the length direction of the main beam.

[0024] Optionally, the spliced ​​timber beam string further comprises:

[0025] A first connecting structure for connecting the main beam and the secondary beam, comprising: a first connecting member provided on one of the side of the main beam and the end of the secondary beam, and a slot provided on one of the side of the main beam and the end of the secondary beam;

[0026] The first connecting member and the slot are plug-fitted and connected, and are connected through a reinforcing bar arranged along the radial direction of the secondary beam.

[0027] Optionally, the first connecting member adjacent to the strut further has a protrusion extending toward the strut, and the protrusion is connected to the adjacent strut via a corner brace.

[0028] Optionally, two ends of the splicing piece are provided with insertion rods, and the ends of the beam sections are provided with insertion holes adapted to the insertion rods.

[0029] The technical solution of the present invention has the following advantages:

[0030] 1. The spliced ​​wooden beam string provided by the present invention includes a main beam, including multiple beam segments, wherein the multiple beam segments form an inverted arch structure that bulges away from the roof; and a splicing piece, which is a metal piece and is arranged at the ends of adjacent beam segments and is fixedly connected to two adjacent beam segments.

[0031] The main beam of the present invention is configured as an inverted arch structure that rises away from the roof, thereby causing the roof to be recessed toward the interior of the building. Compared to the prior art, in which the spliced ​​wooden string beams are configured as an arched structure that arches toward the roof, the present invention reduces the building height. At the same time, the inverted arch structure also provides a new roof structure that increases the range of choices for construction engineers and users.

[0032] Since the inverted arch structure will cause the main beam to bear greater pressure, the beam sections of the main beam of the present invention are connected by metal splicing parts. Since the metal material has strong rigidity and strength, the connection points of the beam sections will not be damaged or dislocated due to the main beam being set as an inverted arch structure that bears greater force, thereby ensuring the bearing capacity of the main beam.

[0033] 2. The spliced ​​wooden beam string provided by the present invention has a main beam made of wood.

[0034] The structure of the present invention can be used on wooden buildings, that is, the main beams are made of wood, so that large-span wooden buildings can avoid the need to set up more support columns by using the structure of the present invention, thereby increasing the usable space in the building, thereby improving the neatness of the wooden building and making the building more environmentally friendly.

[0035] 3. The spliced ​​wooden beam string provided by the present invention further includes a support, on which a second accommodating cavity for accommodating the beam section is provided, and the end of the beam section is embedded in the second accommodating cavity.

[0036] The present invention provides a support at the end of the main beam, and the support is provided with a second accommodating cavity for accommodating the beam section, so that the end of the beam section is embedded in the second accommodating cavity. The main beam is supported and limited by the second accommodating cavity to improve the connection strength between the beam section and the support, so that the main beam can be set as an inverted arch structure, avoiding the multiple beam sections constituting the main beam from loosening along the length direction of the main beam, thereby causing the connection points of the beam sections to be damaged and dislocated.

[0037] 4. In the spliced ​​wooden beam string provided by the present invention, both the end surface and the length surface of the beam segment abut against the corresponding cavity wall of the second accommodating cavity.

[0038] The present invention causes the end surface of the beam segment to abut against the corresponding cavity wall of the second accommodating cavity, so that the second accommodating cavity limits the beam segment along the length direction of the main beam, thereby preventing the multiple beam segments constituting the main beam from loosening along the length direction of the main beam, causing damage and misalignment of the connection points of the beam segments, thereby reducing the bearing capacity of the main beam and causing damage to the main beam.

[0039] The present invention enables the second accommodating cavity to support the beam section by bringing the length surface of the beam section into contact with the corresponding cavity wall of the second accommodating cavity.

[0040] 5. The spliced ​​wooden beam string provided by the present invention further includes hidden cables, wherein the hidden cables are respectively connected to adjacent splicing pieces, and / or the hidden cables are respectively connected to adjacent supports and splicing pieces; and the hidden cables are embedded in the beam section.

[0041] The present invention connects the splicing pieces and supports into a single unit by providing hidden cables. The tension of the hidden cables provides prestressing to each beam segment of the main beam, thereby supporting the main beam and improving its torsional and tensile resistance, allowing the main beam to be configured as an inverted arch structure. Simultaneously, the tension of the hidden cables also restrains each beam segment, preventing the beam segments and splicing pieces from loosening along the length of the main beam, thereby reducing the main beam's bearing capacity and causing damage. Furthermore, the hidden cables can effectively connect adjacent splicing pieces, or adjacent supports and splicing pieces, ensuring that each beam segment is securely and reliably fixed together.

[0042] 6. In the spliced ​​wooden beam string provided by the present invention, a receiving groove is provided along the length direction of the beam section on the side away from the roof; the hidden cable is embedded in the receiving groove.

[0043] The present invention provides a receiving groove on the side of the beam section away from the roof, and embeds the hidden cable in the receiving groove. The receiving groove limits the hidden cable, preventing the hidden cable from moving on the beam section due to the restoring force generated by the hidden cable after being subjected to tension, causing the hidden cable to detach from the beam section and be unable to continue to provide prestress to the main beam, resulting in damage to the main beam; in addition, the hidden cable is embedded in the receiving groove, so that the hidden cable is not exposed, avoiding the hidden cable from occupying space in the building, and improving the neatness and aesthetics of the building.

[0044] 7. In the spliced ​​wooden beam string provided by the present invention, the support is a plate-like structure; the support and the main beam are connected through rebars arranged in a vertical direction along the support.

[0045] The present invention sets up anchor bars arranged along the vertical direction of the support and penetrates the support and the main beam, so that the tension exerted on the support is transmitted to the main beam through the anchor bars. Since the anchor bars penetrate the main beam, the tension exerted on the support will be evenly transmitted to the main beam as a whole, rather than to one side. This avoids the problem in the prior art that the connecting piece for connecting the cable is set on one side of the main beam, which causes the main beam to bulge and bend to the other side after being subjected to force, and the tension generates a torsional torque on the connecting piece, causing it to damage the main beam and detach. This increases the pressure that the main beam and the support can withstand, so that the main beam can be set as an inverted arch structure.

[0046] 8. The spliced ​​wooden tensioned beam provided by the present invention further includes cables connected to the supports at both ends of the main beam respectively; a support rod, one end of which is connected to the main beam and the other end is connected to the cables to provide prestress to the main beam.

[0047] The present invention provides prestressing force to the main beam by arranging cables connecting supports at both ends of the main beam and arranging struts connecting the main beam and the cables.

[0048] 9. The spliced ​​wooden beam string provided by the present invention further includes a secondary beam, which is arranged in the radial direction of the main beam and connected to the main beam, and a plurality of the secondary beams are arranged along the length direction of the main beam.

[0049] The present invention arranges secondary beams along the radial direction of the main beam, and multiple secondary beams are arranged along the length direction of the main beam, so that the secondary beams and the main beam support the roof at the same time, thereby increasing the stress points on the roof that are supported by the force, making the force more balanced, and preventing the roof from being deformed due to a small number of stress points.

[0050] 10. The spliced ​​wooden tensioned beam provided by the present invention also includes a first connecting structure for connecting the main beam and the secondary beam, which includes: a first connecting member arranged on one of the side of the main beam and the end of the secondary beam, and a slot arranged on one of the side of the main beam and the end of the secondary beam; the first connecting member and the slot are plug-in connected, and are connected through a rebar member arranged along the radial direction of the secondary beam.

[0051] The present invention provides a first connecting piece to connect the main beam and the secondary beam. The first connecting piece and the slot are plugged in and connected to play a limiting role to prevent the secondary beam and the main beam from offsetting or moving. The first connecting piece and the slot are connected through the rebar piece arranged along the radial direction of the secondary beam, so that the pressure on the secondary beam can be evenly transferred to the main beam. Compared with the first connecting piece being connected to one side of the secondary beam, it can avoid the secondary beam being bent to the other side due to force, and the problem of the first connecting piece being detached from the secondary beam.

[0052] 11. In the spliced ​​wooden beam string provided by the present invention, the first connecting member adjacent to the strut further has a protrusion extending toward the strut, and the protrusion is connected to the adjacent strut via a corner brace.

[0053] The first connecting member adjacent to the support rod of the present invention is provided with a protrusion, which is connected to the support rod through a corner brace, so that the secondary beam connected to the first connecting member is connected to the support rod through the corner brace. The tension applied to the support rod by the corner brace ensures that the support rod and the cable remain stable, avoiding the cable from becoming unstable and flipping.

[0054] 12. The spliced ​​wooden beam string provided by the present invention has plug rods at both ends of the spliced ​​piece, and sockets adapted to the plug rods are provided at the ends of the beam sections.

[0055] The splicing piece of the present invention is provided with plug rods at both ends, and the end of the beam section is provided with a plug hole adapted for the plug rod, so that the splicing piece and the beam section are plugged and connected, which can prevent the splicing piece and the beam section from moving along the radial direction of the main beam; at the same time, because the plug rod extends into the beam section, it can balance the pressure on the connection position of the beam section and the splicing piece, avoiding the concentration of force at the connection position causing damage to the end of the beam section.

[0074] Example 1

[0075] This embodiment provides a spliced ​​wooden beam string. Figures 1-10 Shown, including

[0076] The main beam 1 is not limited to the shape of the main beam 1 in this embodiment. The cross section perpendicular to the length direction can be rectangular, circular, etc. The main beam 1 includes a plurality of beam sections 15, such as Figure 1 As shown, the plurality of beam sections 15 form an inverted arch structure that bulges away from the roof, so as to reduce the height of the building and improve the aesthetics of the building.

[0077] The splicing piece 16 is a metal piece, which is provided at the ends of the adjacent beam sections 15 and is fixedly connected to the two adjacent beam sections 15 respectively.

[0078] This embodiment does not specifically limit the structure of the splicing piece 16. As a preferred solution, Figure 2 As shown, a plurality of plug rods are provided at both ends of the splicing piece 16, and a socket adapted to the plug rods is provided at the end of the beam section 15, so that the splicing piece 16 is plugged and connected to the beam section 15; of course, in other embodiments, the splicing piece 16 can also be set as a sleeve structure adapted to the shape of the beam section 15, and be sleeved with the ends of the two adjacent beam sections 15 to fixedly connect the two beam sections 15.

[0079] The support 8 is preferably a metal part, which is arranged at both ends of the main beam 1, and is provided with a second accommodating cavity 17 for accommodating the beam section 15. The end of the beam section 15 is embedded in the second accommodating cavity 17, and the end surface 20 and the length surface 21 of the beam section 15 are both in contact with the corresponding cavity wall of the second accommodating cavity 17, wherein the end surface 20 is in contact with the side cavity wall of the second accommodating cavity 17, so that the second accommodating cavity 17 has a limiting effect on the beam section 15 along the length direction of the main beam 1, avoiding the multiple beam sections 15 constituting the main beam 1 from loosening along the length direction of the main beam 1, causing the connection points of the beam sections 15 to be damaged and dislocated, thereby reducing the bearing capacity of the main beam 1 and causing damage to the main beam 1, and its length surface 21 is in contact with the bottom cavity wall of the second accommodating cavity 17, so that the second accommodating cavity 17 has a supporting effect on the beam section 15, such as Figure 3and Figure 11 As shown, the top surface of the support 8 and the bottom cavity wall of the second accommodating cavity 17 both support the main beam 1. By increasing the load-bearing surface between the main beam 1 and the support 8, the force per unit area of ​​the load-bearing surface of the main beam 1 is reduced, thereby avoiding the phenomenon that the main beam 1 is deformed or even bent and broken due to the relatively concentrated support force of the support 8 on the main beam 1.

[0080] This embodiment does not limit the connection structure between the support 8 and the main beam 1. Preferably, Figure 1 and Figure 3 As shown, a first accommodating cavity is provided at the end of the main beam 1, the opening of the first accommodating cavity is located at the bottom of the main beam 1, and the first accommodating cavity is located on the axis of the main beam 1.

The support 8 is embedded in the first accommodating cavity, the protrusion is embedded in the second accommodating cavity 17, and abuts against the second accommodating cavity 17, and the support 8 and the main beam 1 are connected through the anchor bolt 11 arranged in the vertical direction of the support 8; of course, in other embodiments, the end of the main beam 1 can be directly embedded in the second accommodating cavity 17 without the need to set the first accommodating cavity.

[0081] This embodiment does not limit the structure of the support 8. Preferably, Figure 3 As shown, the support 8 is a plate-like structure provided with a second accommodating cavity 17. The end of the support 8 away from the cable 5 is located in the first accommodating cavity, and is connected to the main beam 1 through a plurality of anchor bolts 11 arranged in a vertical direction along the support 8. The end of the support 8 close to the cable 5 forms an ear plate suitable for connecting the cable 5 below the main beam 1.

[0087] This embodiment does not limit the connection method between the support rod 6 and the main beam 1. It can be connected by simply inserting the end portion into the main beam 1. Preferably, Figure 4 As shown, the end of the support rod 6 of this embodiment is set to a T-shaped structure, and the plate-like component inserted into the main beam 1 in the T-shaped structure is connected to the main beam 1 through the anchor member 11.

[0088] The present embodiment does not limit the connection method between the support rod 6 and the cable 5. A through hole for the cable 5 to pass through can be provided at the end of the support rod 6, or a groove for the cable 5 to be embedded can be provided at the end of the support rod 6. In the present embodiment, a through-hole-shaped cable clamp is provided. When the cables 5 are provided in pairs, such as Figure 4 As shown, the cables 5 are arranged on both sides of the strut 6 .

[0089] Hidden cables 18. Preferably, the splicing pieces 16 of this embodiment are provided with multiple hidden cables 18, and the hidden cables 18 located between the splicing pieces 16 are respectively connected to adjacent splicing pieces 16, and the hidden cables 18 located between the supports 8 and the splicing pieces 16 are respectively connected to adjacent supports 8 and splicing pieces 16, so that the supports 8, splicing pieces 16 and multiple hidden cables 18 of this embodiment are connected into a whole, so as to further provide prestress to the main beam 1, so that the main beam 1 can be set as an inverted arch structure; of course, in other embodiments, when only one splicing piece 16 is provided, the hidden cables 18 are only respectively connected to the adjacent supports 8 and splicing pieces 16; or in other embodiments, the hidden cables 18 are only provided between adjacent splicing pieces 16, and at this time they are only respectively connected to the adjacent splicing pieces 16.

[0090] The hidden cable 18 is embedded in the beam section 15. Preferably, Figure 2 As shown, the beam section 15 is provided with a receiving groove 19 along the length direction of the beam section 15 on the side away from the roof, and the hidden cable 18 is embedded in the receiving groove 19, so that when this embodiment is in use, the use status and whether the hidden cable 18 is damaged can be directly observed through the receiving groove 19; of course, in other embodiments, a through hole can be provided on the beam section 15 along its length direction, and the hidden cable 18 is located in the through hole.

[0091] A joint is provided at the end of the hidden cable 18, and the end of the splicing piece 16 is located in the accommodating groove 19 and is hingedly connected to the corresponding joint; preferably, when the ear plate of the support 8 connected to the cable 5 is located in the accommodating groove 19, the joint at the end of the hidden cable 18 can be directly hingedly connected to the ear plate, and when the ear plate of the support 8 connected to the cable 5 does not overlap with the accommodating groove 19, the support 8 is provided with another ear plate for hingedly connecting the end joint of the hidden cable 18; of course, when the ear plate of the support 8 connected to the cable 5 is located in the accommodating groove 19, another ear plate for hingedly connecting the end joint of the hidden cable 18 can also be separately provided.

[0092] The secondary beam 2 is arranged in the radial direction of the main beam 1 and is connected to the main beam 1. A plurality of the secondary beams 2 are arranged along the length direction of the main beam 1, so that the secondary beams 2 and the main beam 1 support the roof at the same time, thereby increasing the number of stress points on the roof that are supported by the force, making the force more balanced, and preventing the roof from deforming due to a small number of stress points.

[0093] The first connecting structure is used to connect the main beam 1 and the secondary beam 2. It includes a first connecting member 9 arranged on the side of the main beam 1, and a slot arranged at the end of the secondary beam 2, and the slot is located on the axis of the secondary beam 2. The first connecting member 9 and the slot are plugged in and connected, and are connected through a rebar 11 arranged along the radial direction of the secondary beam 2; this embodiment does not specifically limit the first connecting structure. The first connecting member 9 can also be arranged at the end of the secondary beam 2, and the slot is arranged on the side of the main beam 1. The plug-in connection between the first connecting member 9 and the slot can play a limiting role to prevent the secondary beam 2 from offsetting or moving with the main beam 1. The first connecting member 9 and the slot are connected through the rebar 11 arranged along the radial direction of the secondary beam 2, which can make the pressure on the secondary beam 2 evenly transferred to the main beam 1, avoiding the problem that the secondary beam 2 is unevenly stressed and bulges to one side, and causes the first connecting member 9 to be detached from the secondary beam 2.

[0094] This embodiment does not limit the structure of the first connecting member 9. Preferably, Figure 6 and Figure 7As shown, the first connecting member 9 of this embodiment is a T-shaped structure composed of a horizontal plate 14 and a vertical plate 13. The horizontal plate 14 is fitted and connected to the main beam 1, and the vertical plate 13 is connected to the slot on the end of the secondary beam 2 by plugging. Further, the horizontal plate 14 is connected to the main beam 1 through a plurality of embedded steel bars 11 arranged perpendicular to the axial direction of the main beam 1. When secondary beams 2 are provided on both sides of the main beam 1, the above-mentioned plurality of embedded steel bars 11 penetrate the horizontal plates 14 and the main beam 1 on both sides of the main beam 1, and the vertical plate 13 is connected to the secondary beam 2 through a plurality of embedded steel bars 11 arranged perpendicular to the axial direction of the secondary beam 2. Since the horizontal plate 14 is located between the main beam 1 and the secondary beam 2, and the vertical plate 13 is located inside the slot, the first connecting member 9 will not be exposed. When the main beam 1 and the secondary beam 2 are made of wood, the metal parts can be avoided from being exposed, thereby enhancing the aesthetics; of course, it can also be set to be a horizontal plate 14 that is fitted and connected to the end of the secondary beam 2, and the vertical plate 13 is connected to the slot on the main beam 1 by plugging.

[0095] This embodiment does not specifically limit the connection method of the main beam 1 and the secondary beam 2. They can also be connected by a mortise and tenon structure, and the first connection structure may not be provided in this case.

[0096] Furthermore, in order to reduce the force transmitted from the secondary beam 2 to the main beam 1 and prevent the occurrence of instability, Figure 4 and Figure 5 As shown, the first connecting member 9 adjacent to the strut 6 also has a protrusion extending toward the strut 6, and the protrusion is connected to the strut 6 adjacent to it through a corner brace 7. Secondary beams 2 are provided on both sides of the main beam 1, and a corner brace 7 is symmetrically provided on both sides of the strut 6 to prevent the strut 6 from being tilted due to the tension of the corner brace 7 on only one side, thereby causing the cable 5 to become unstable and flip over.

[0097] The present embodiment does not specifically limit the structure of the corner support 7, which can be a cable member or a pull rod member fixedly connected to the first connecting member 9 and the support rod 6 by screws or welding. Preferably, Figure 4 As shown, the corner brace 7 is a tie rod type corner brace, which has a smaller cross-section, reduces the space occupied by the interior of the building, and improves the aesthetics of the building.

[0098] In order to further reduce the pressure on the main beam 1 and the secondary beam 2, a roof support 12 is provided for auxiliary support of the roof, such as Figure 8 As shown, the roof support member 12 is arranged between the main beam 1 and the secondary beam 2 connected to form a M-shaped support structure, and a second connecting structure for connecting the main beam 1, the secondary beam 2 and the roof support member 12 is provided, as shown in FIG. Figure 8 and Figure 9As shown, the second connecting structure includes a T-shaped structure composed of a horizontal plate 14 and a vertical plate 13, and a connecting plug plate 10 arranged on both sides of the vertical plate 13. The horizontal plate 14 is connected to the main beam 1, and a rebar 11 is provided to pass through the horizontal plate 14 and the main beam 1. The vertical plate 13 is connected to the slot on the end of the secondary beam 2 by fitting and plugging, and a rebar 11 is provided to pass through the vertical plate 13 and the secondary beam 2. The connecting plug plate 10 is fixedly connected to the slot on the roof support 12 by fitting and plugging, and a rebar 11 is further provided to pass through the connecting plug plate 10 and the roof support 12.

[0099] The support column 4 is preferably a metal part, which is used to support the bearing 8, so that the tension of the cable 5 is directly transmitted to the support column 4 through the bearing 8. Compared with the prior art in which the main beam 1 is directly connected to the support column 4, the connecting part of the cable 5 is located on one side of the support column 4, so that the tension of the cable 5 needs to act on the main beam 1 first, and then be transmitted to the support column 4 by the main beam 1. In this embodiment, since the bearing 8 connecting the cable 5 is set on the support column 4, the tension of the cable 5 is avoided from acting on the two ends of the main beam 1 in opposite directions, causing the ends of the main beam 1 to be damaged by excessive force.

[0100] This embodiment does not specifically limit the connection method between the support column 4 and the support 8. The two can be welded together, or a boss can be provided at the bottom of the support 8 and inserted into the groove at the top of the support column 4, so that the tension of the cable 5 is directly transmitted to the support column 4 through the support 8, avoiding the tension acting on the end of the main beam 1 and causing damage to the main beam 1.

[0101] Frame beam 3, such as Figure 10 As shown, the middle part is connected to the support column 4, and the two can be directly welded, or the middle part of the frame beam 3 can be sleeved on the support column 4, and the two ends of the frame beam 3 are embedded in the secondary beam 2. The frame beam 3 further supports the secondary beam 2, and the pressure on the frame beam 3 directly acts on the support column 4, thereby reducing the pressure on the main beam 1 and improving the service life of the main beam 1.

[0102] This embodiment does not specifically limit the material of the main beam 1 and the secondary beam 2. This embodiment is preferably used in wooden buildings, that is, the main beam 1 is made of wood and the secondary beam 2 is also made of wood. This can effectively solve the problem of small span caused by insufficient rigidity of wooden structures. Of course, in other embodiments, this embodiment can also be used in steel buildings and steel-concrete buildings, that is, the main beam 1 and the secondary beam 2 are steel components.

[0103] Of course, this embodiment does not specifically limit the connection method between the first accommodating cavity and the support 8. In other embodiments, the support 8 is fixed in the first accommodating cavity by a snap-fit ​​structure, and the above-mentioned snap-fit ​​structure is a hook and a buckle.

[0104] Of course, this embodiment does not specifically limit the fixing method of the splicing piece 16 and the beam section 15. In other embodiments, a socket is provided at the central position of the end of the beam section 15, and the splicing piece 16 is embedded and fixed in the accommodating cavity surrounded by the sockets of the two adjacent beam sections 15 and fixed by hooks and buckles.

[0105] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
