Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to a combined beam of glued laminated wood and T-shaped steel. Background Art

[0002] Compared to traditional concrete structures, timber structures can significantly reduce environmental pollution and meet the needs of green, low-carbon urban development. Wood is an anisotropic material. While its tensile properties along the grain are excellent, its mechanical properties in all other directions are relatively poor. Furthermore, wood is significantly affected by the environment during practical use, making it prone to moisture content fluctuations and the development of crisscrossing cracks.

[0003] The beam-column joints in wooden structures are hinged or semi-rigid, making it difficult to achieve complex structures such as large spans and large cantilevers. Steel-wood composite structures are often used in modern wooden building applications.

[0004] Existing steel-wood composite structures are generally designed separately, that is, steel columns and wooden beams are connected by connectors. They are affected by the structural layout plan and load distribution, and need to be redesigned each time according to different design plans. Therefore, the product standardization is low and cannot meet the development needs of prefabricated types.

[0005] For example, the use of steel wrapped in wood-grain aluminum panels for imitation wood structures effectively prevents moisture-induced deformation and cracking. However, this method makes it difficult to achieve synergy between glulam and steel, failing to fully utilize the beneficial properties of both materials, resulting in a certain amount of material waste. Furthermore, the need to embed bolts at intervals in the steel components to connect the aluminum panels increases the construction process and reduces the efficiency of wooden buildings. Utility Model Content

[0006] In order to improve the construction efficiency of wooden buildings, the present application provides a composite beam of glued laminated timber and T-steel.

[0007] This application provides a composite beam of glulam and T-steel using the following technical solutions:

[0008] A composite beam of glued laminated wood and T-shaped steel comprises glued laminated wood and T-shaped steel, wherein the glued laminated wood is provided with a plurality of blocks, installation grooves are pre-set between the plurality of glued laminated woods, the T-shaped steels are arranged in the installation grooves, the plurality of glued laminated woods cover the T-shaped steels, and the plurality of glued laminated woods are connected by adhesive.

[0009] By adopting the above technical solution, during prefabrication, workers install the T-shaped steel tightly in the installation slot, and then use adhesive to connect the remaining glued wood one by one to cover the T-shaped steel, realizing the prefabrication of the composite beam. The workers use the inverted T-shaped steel as the tensile zone, fully utilizing the tensile properties of the T-shaped steel. The glued wood on both sides provides lateral support for the T-shaped steel, reducing the possibility of local buckling of the beam. At the same time, the T-shaped steel can also serve as a steel plate connector at the beam-column node, which can simplify the method of connecting the beam and column nodes. Compared with existing imitation wood structures, the step of pre-embedded bolts is omitted, reducing construction steps and improving the construction efficiency of wooden buildings.

[0010] Optionally, structural adhesive is filled between the T-shaped steel and the groove wall of the installation groove.

[0011] By adopting the above technical solution, the mounting slot is larger than the T-steel for easier installation. This leaves a slight gap between the slot and the T-steel, affecting the overall beam's load-bearing stability. Workers used structural adhesive to fill the gap between the slot and the T-steel, reducing the possibility of the T-steel moving within the slot and improving the overall beam's load-bearing stability and load-bearing capacity.

[0012] Optionally, the T-shaped steel includes a horizontal portion and a vertical portion, and a plurality of stabilizing bolts are passed between the plywood and the vertical portion. The stabilizing bolts are evenly distributed along the length direction of the plywood, and the threads on the stabilizing bolts are equipped with stabilizing nuts, which press against the plywood.

[0013] By adopting the above technical solution, the combination of the stabilizing bolts and the stabilizing nuts is used to enhance the connection strength between the T-steel and the glulam, reduce the possibility of relative movement between the glulam and the T-steel, reduce the possibility of damage to the glulam, and improve the safety of the beam.

[0014] Optionally, a first self-tapping screw is passed between the plywood and the horizontal portion, and an end of the first self-tapping screw is flush with the surface of the plywood.

[0015] By adopting the above technical solution, the first self-tapping screw is used to further enhance the connection strength between the T-shaped steel and the glued timber, thereby improving the safety of the beam.

[0016] Optionally, a stabilizing groove is provided between several of the glulams, a stabilizing steel plate is provided in the stabilizing groove, a plug-in groove is opened on the stabilizing steel plate, a stabilizing step is provided on the vertical part, the vertical part passes through the plug-in groove, the stabilizing steel plate fits the stabilizing step, and a connecting component is provided on the vertical part to limit the stabilizing steel plate.

[0017] By adopting the above technical solution, the staff first passes the vertical part through the socket slot, and then uses the connecting assembly to connect the stabilizing steel plate to the vertical part, so that the stabilizing steel plate and the horizontal part correspond to each other, further increasing the load of the beam while further reducing the possibility of local buckling in the middle position of the beam in the length direction.

[0018] Optionally, the connecting assembly includes a pressure stabilizing plate and a second self-tapping screw, a penetration groove is opened on the vertical part, the pressure stabilizing plate passes through the penetration groove and is located between the stabilizing steel plate and the groove wall of the penetration groove, a plurality of second self-tapping screws are arranged on the plywood, the second self-tapping screws pass through the plywood, the vertical part, the pressure stabilizing plate and the stabilizing steel plate in sequence, and are threadedly engaged with the plywood, the vertical part, the pressure stabilizing plate and the stabilizing steel plate, and the end of the second self-tapping screw is flush with the surface of the plywood.

[0019] By adopting the above technical solution, when installing the stabilizing steel plate, the staff will pass the stabilizing plate through the penetration groove so that the stabilizing plate is located between the groove wall of the penetration groove and the stabilizing steel plate, and then glue the plywood so that the stabilizing steel plate is located inside the plywood. Finally, the second self-tapping screw will be passed through the plywood, the vertical part and the stabilizing steel plate in sequence until the end of the second self-tapping screw is flush with the surface of the plywood, thereby restricting the stabilizing steel plate and realizing the installation of the stabilizing steel plate.

[0020] Optionally, a plug-in hole is opened between the plurality of glued woods, a stabilizing pin is inserted into the plug-in hole, and the stabilizing pin is made of wood material.

[0021] By adopting this technical solution, the glulam timbers are connected solely with adhesive. When the beam is subjected to stress, there is a risk of local relative movement or debonding between adjacent glulam timbers, which could compromise the beam's safety. By utilizing the friction between the stabilizing pins and the glulam timbers, the staff further increased the strength of the connections between the timbers, reducing the possibility of relative movement or debonding between adjacent timber timbers.

[0022] Optionally, the surface of the glued wood is coated with a waterproofing agent.

[0023] By adopting this technical solution, glulam swells when exposed to water. Over time, after the water evaporates, the wood may shrink. This alternation between swelling and shrinkage can damage the wood, shortening its lifespan. By using a waterproofing agent to isolate the wood from water, the swelling is reduced and its lifespan is extended.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. During prefabrication, workers install the T-shaped steel tightly into the installation slots, then use adhesive to connect the remaining glulam pieces one by one to cover the T-shaped steel, completing the prefabrication of the modular beam. The workers use the inverted T-shaped steel as the tension zone, fully utilizing the tensile properties of the T-shaped steel. The glulam on both sides provides lateral support for the T-shaped steel, reducing the possibility of localized buckling of the beam. The T-shaped steel also serves as a steel plate connector at the beam-column joint, simplifying the beam-column connection. Compared to existing imitation wood structures, this eliminates the need for pre-embedded bolts, reduces construction steps, and improves the efficiency of wooden buildings.

[0031] The following is combined with Figures 1-4 This application is described in further detail.

[0032] The present application discloses a composite beam of glued laminated wood and T-shaped steel. Figure 1 and Figure 2 The glulam and T-steel composite beam includes a plurality of glulam timbers 1 and T-steel 2. The glulam timbers 1 are connected by adhesive, which in this embodiment is structural adhesive. Mounting slots are defined between the glulam timbers 1. The T-steel 2 is mounted within the mounting slots and connected to the mounting slots by structural adhesive.

[0033] Reference Figure 2The T-shaped steel 2 includes a horizontal portion 21 and a vertical portion 22, which are integrally formed. Several first self-tapping screws 3 are evenly distributed along the length of the glulam 1. These screws penetrate the glulam 1 and the horizontal portion 21, threaded into the horizontal portion 21, and the ends of the screws are flush with the surface of the glulam 1. These screws are used to strengthen the connection between the T-shaped steel 2 and the glulam 1, thereby enhancing the safety of the beam.

[0034] Reference Figure 2 Several stabilizing bolts 4 are installed along the length of the sidewalls of the glulam 1. These bolts 4 pass through the glulam 1 and the vertical portion 22 in sequence. Washers are fitted over the bolts 4, and stabilizing nuts 41 are threaded into the bolts 4. These nuts 41 press against the washers. The combination of these bolts 4 and nuts 41 reduces the possibility of relative movement between the glulam 1 and the T-shaped steel 2, further improving the safety of the beam.

[0035] Reference Figure 2 and Figure 3 A stabilizing groove is provided between the plurality of glulam members 1. A stabilizing steel plate 5 is provided in the stabilizing groove. A plug-in groove 51 is provided on the stabilizing steel plate 5 at a position corresponding to the vertical portion 22. A stabilizing step 221 is provided on one end of the vertical portion 22 away from the horizontal portion 21. The vertical portion 22 is plugged into the plug-in groove 51, and the stabilizing steel plate 5 contacts the stabilizing step 221.

[0036] Reference Figure 2 and Figure 3 A connecting assembly 6 is provided on the vertical portion 22, comprising a pressure stabilizing plate 61 and a second self-tapping screw 62. A through-slot 222 is provided on the vertical portion 22 at a position corresponding to the stabilizing steel plate 5. The pressure stabilizing plate 61 passes through the through-slot 222 and is located between the sidewall of the through-slot 222 and the stabilizing steel plate 5. Several second self-tapping screws 62 are evenly distributed along the length of the glulam 1. The second self-tapping screws 62 pass through the glulam 1, the vertical portion 22, the pressure stabilizing plate 61, and the stabilizing steel plate 5 in sequence, and are threadedly engaged with the glulam 1, the vertical portion 22, the pressure stabilizing plate 61, and the stabilizing steel plate 5. The end of the second self-tapping screw 62 is flush with the surface of the glulam 1.

[0037] When connecting the stabilizing steel plate 5, the staff will put the stabilizing steel plate 5 on the vertical part 22, then pass the pressure stabilizing plate 61 through the penetration groove 222, and then glue the plywood 1 to cover the stabilizing steel plate 5, and finally pass the second self-tapping screw 62 through the plywood 1, the vertical part 22, the pressure stabilizing plate 61 and the stabilizing steel plate 5 in turn to complete the installation of the stabilizing steel plate 5.

[0038] Reference Figure 4To further enhance the connection strength between the glulams 1, several insertion holes are provided between the glulams 1, evenly distributed along the length of the glulams 1. Securement pins 7 are inserted into the insertion holes. The securement pins 7 are made of wood, and their ends are flush with the surface of the glulams 1.

[0039] Reference Figure 1 In order to extend the service life of the glued wood 1, the surface of the glued wood 1 is coated with a waterproofing agent. The waterproofing agent in this embodiment is wood wax oil. The waterproofing agent is used to isolate the contact between water and the glued wood 1, reducing the possibility of the glued wood 1 swelling when it comes into contact with water.

[0040] The implementation principle of a combined glulam and T-steel beam according to an embodiment of the present application is as follows: when assembling the beam, the staff places the T-steel 2 in the installation groove of the first glulam 1, and then glues several glulams 1 in sequence, and then puts the stabilizing steel plate on the vertical part 22, which fits the stabilizing step 221, passes the stabilizing plate 61 through the penetration groove 222, and then glues the remaining glulams 1 to wrap the T-steel 2 and the stabilizing steel plate 5, passes the second self-tapping screw 62 through the glulam 1, the vertical part 22, the stabilizing plate 61 and the stabilizing steel plate 5, and then passes the stabilizing bolt 4 through the glulam 1 and the vertical part 22, and then tightens the glulam 1 with the stabilizing nut 41, passes the first self-tapping screw 3 through the glulam 1 and the horizontal part 21, and then inserts the stabilizing pin 7 into the plug-in hole, and finally applies a waterproofing agent on the surface of the glulam 1 to realize the assembly of the beam.

[0041] The staff used the inverted T-steel 2 as the tension zone, fully utilizing the tensile properties of the T-steel 2, and used the glued wood 1 on both sides to provide lateral support for the T-steel 2, reducing the possibility of local buckling of the beam. At the same time, the T-steel 2 can also serve as a steel plug-in connector for the beam-column node, which can simplify the method of connecting the beam-column node. Compared with the existing imitation wood structure, the step of embedding bolts is omitted, the construction steps are reduced, and the construction efficiency of wooden buildings is improved.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
