Description

Technical Field

[0001] The invention relates to the technical field of reinforced rigid bending-resistant glued laminated wood columns, and in particular to reinforced rigid bending-resistant glued laminated wood columns. Background Art

[0002] With the rapid development of my country's economy, the application of wood structure in the field of architecture and bridges is becoming more and more extensive. When considering the structural system and appearance design, designers are not only limited to the most basic functional requirements of the building, but also begin to consider the beautiful architectural form. In addition, the optimization of the overall utilization effect of space and the establishment of environmentally friendly green buildings have become the higher pursuit of modern engineering and technical personnel. Therefore, in this context, the modern wood structure system came into being. Although my country has a long history of wood structure construction, my country is still far behind developed countries in the application and research of modern glued wood structures. Therefore, in order to promote the development and application of modern glued wood structures in China and build an environmentally friendly and resource-saving society, it is necessary to strengthen the research and application of glued wood in the field of construction.

[0003] As one of the main building materials, wood has the advantage of being renewable compared to reinforced concrete. Although steel can also be recycled, it will inevitably consume a lot of energy during the recycling process, but wood does not have this problem. In addition, wood has good thermal insulation properties and can regulate indoor air dryness and humidity, which is beneficial to human health. Modern wooden structures have good seismic resistance, a high degree of industrialization, and are natural prefabricated structures with simple construction processes and short construction time. Therefore, the development of modern wooden structures and the promotion of their application scope are in line with the national strategy of sustainable development.

[0004] Modern wood structure buildings are mainly divided into three categories: heavy wood structure, light wood structure and log structure. The main load-bearing component of heavy wood structure is glued wood, so the glued wood structure in the wood structure system is the mainstream in the current application of modern wood structure system. Because the log structure will inevitably lead to waste of resources, and the original defects on the logs are difficult to avoid, it is not economical in the application of the entire wood. Glued wood is an engineering wood formed by stacking smaller solid wood sawn timber under pressure with cold-curing adhesives. While maintaining the traditional beauty of wood, it also has good fire resistance and insulation. Compared with log structure, its force properties are more uniform and the internal force distribution is more reasonable, but its own strength and hardness are very poor, so it will be limited to some scenes with small bearing capacity, and it will deform when subjected to slightly stronger forces, reducing the strength and service life of glued wood. Summary of the invention

[0005] The invention provides a reinforced rigid bending-resistant glued wood column, which improves the bearing strength of the glued wood column, reduces the deformation force of the glued wood column, and improves the use strength and service life of the glued wood column.

DETAILED DESCRIPTION

[0037] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example

[0039] like Figure 1 to Figure 6 As shown, this embodiment proposes a reinforced rigid bending-resistant glued laminated timber column, including a glued laminated timber column 11;

[0040] The first positioning block 12 is bonded to the upper side of the glued wood column 11;

[0041] The second positioning block 13 is fixedly connected to the lower side of the glued wood column 11, and the base 14 is fixedly bonded to the lower side of the second positioning block 13;

[0042] A pressure-resistant component for improving the pressure resistance of the glued wood column 11 is connected between the first clamping block 12 and the second clamping block 13;

[0043] The pressure-resistant components can be used to distribute and offset the forces acting on the glued wood column 11, so that the glued wood column 11 and the pressure-resistant components form a whole, thereby improving the bearing strength of the glued wood column 11, allowing the glued wood column 11 to be applied to more usage scenarios, thereby improving the economic benefits of the glued wood column 11, improving the aesthetics of the building, reducing the deformation force of the glued wood column 11, and improving the use strength and service life of the glued wood column 11.

[0044] like Figure 1 to Figure 4 As shown, the pressure-resistant assembly includes a first steel bar 21 and a plurality of second steel bars 22. The first steel bar 21 and each of the second steel bars 22 are slidably connected to the glued wood column 11, and the upper side surfaces of the first steel bar 21 and each of the second steel bars 22 are tangently abutted in sequence;

[0045] Each limiting column 23 is tangentially connected to the first steel bar 21 and the adjacent second steel bar 22 or between two adjacent second steel bars 22, and each limiting column 23 is connected to the glued wood column 11 and the first blocking block 12;

[0046] The bearing strength of the glued wood column 11 is improved by the strength of the first steel bar 21 and the plurality of second steel bars 22 themselves, and then concrete is injected into the glued wood column 11 to increase the connection relationship between the first steel bar 21 and the plurality of second steel bars 22 and the glued wood column 11. However, when this force exceeds the bearing capacity of the first steel bar 21 or the second steel bar 22, because the strength of the first steel bar 21 or the second steel bar 22 is greater than the strength of the glued wood column 11, the first steel bar 21 or the second steel bar 22 will squeeze the inner side of the glued wood column 11 toward the outer side, causing damage to the glued wood column 11. Therefore, the first steel bar 21 and the plurality of second steel bars 22 are sequentially abutted against each other so that the first steel bar 21 and the plurality of second steel bars 22 can form a whole, and the force they bear will be shared by the first steel bar 21 and the plurality of second steel bars 22 in turn, thereby further improving the strength of the glued wood column 11. Then, through the action of each limit column 23, the connection relationship between the first steel bar 21 and the plurality of second steel bars 22 is improved to prevent the first steel bar 21 and the plurality of second steel bars 22 from detaching.

[0047] like Figure 1 to Figure 4 As shown, a plurality of locking through holes 111 are formed on the glued wood column 11, and each locking blind hole 112 is formed on one side of each locking through hole 111;

[0048] The first steel bar 21 and each second steel bar 22 are slidably connected to the inner wall of each positioning through hole 111, the lower end of each limiting column 23 is slidably abutted against the inner wall of each positioning blind hole 112, and the upper end of each limiting column 23 is slidably abutted against the inner wall of the first positioning block 12;

[0049] One end of the long axis of the first steel bar 21 and each second steel bar 22 can be sequentially clamped in the glued wood column 11 along the locking through hole 111, and then the aperture of the locking through hole 111 is slightly larger than the diameter of the first steel bar 21 and each second steel bar 22, so that the first steel bar 21 and each second steel bar 22 can be inserted more easily. At the same time, concrete is filled in the gap between the first steel bar 21 and each second steel bar 22 and the locking through hole 111, thereby improving the connection strength between the glued wood column 11 and the first steel bar 21 and several second steel bars 22.

[0050] like Figure 1 to Figure 4 As shown, the positioning plate 15 is fixedly bonded between the glued wood column 11 and the first positioning block 12, a plurality of positioning holes 151 are provided on the positioning plate 15, and each threaded hole 152 is provided on one side of each positioning hole 151;

[0051] Each positioning hole 151 is coaxially arranged with each locking through hole 111, and each threaded hole 152 is coaxially arranged with each locking blind hole 112;

[0052] The first steel bar 21 and each second steel bar 22 are in contact with the inner wall of the positioning hole 151 and the inner wall of each positioning through hole 111;

[0053] Each limiting column 23 is threadedly connected to each threaded hole 152;

[0054] Through the threaded connection relationship between the positioning plate 15 and each limiting column 23, the limiting effect of each limiting column 23 on the first steel bar 21 and the plurality of second steel bars 22 is further improved, the deformation resistance of each limiting column 23 to withstand the bearing force is improved, and the force of the deformation of each limiting column 23 on the inner wall of the positioning blind hole 112 is transferred to the threaded hole 152, thereby reducing the squeezing effect of the limiting column 23 on the inner side of the glued wood column 11, thereby improving the service strength and service life of the glued wood column 11.

[0055] like Figure 3 and Figure 5 As shown, the latching groove 113 is provided on the upper side of the plywood column 11, and the latching ring 153 is provided on the side of the latching plate 15 facing the plywood column 11, and the latching ring 153 and the latching groove 113 are interlocked;

[0056] By engaging the locking ring 153 with the locking groove 113 , the contact area between the locking ring 153 and the locking groove 113 is increased, thereby increasing the adhesive strength between the two and making the connection between the two tighter.

[0057] like Figure 1 to Figure 4 and Figure 6 As shown, a plurality of limiting holes 114 are provided in the middle section of the glued wood column 11, each limiting hole 114 is provided between two positioning through holes 111, the axis of the limiting hole 114 is perpendicular to the axis of the positioning through hole 111, and each reinforcing rod 24 is fixedly connected in each limiting hole 114;

[0058] The locking through hole 111 is not connected to the limiting hole 114;

[0059] When the glued wood column 11 is subjected to load, the glued wood column 11 will deform to one side. However, the strength of the material of the glued wood column 11 itself is inconsistent with the strength of the first steel bar 21 and the second steel bar 22. Although the first steel bar 21 and the second steel bar 22 offset the load force, due to the inconsistency of the material strength, the glued wood column 11 itself will bend and deform, and then internal extrusion and tearing will occur. The reinforcing rod 24 can offset this bending deformation and further improve the overall strength of the first steel bar 21 and the second steel bar 22.

[0060] like Figure 5 and Figure 6As shown, the lower end of the first steel bar 21 is fixedly connected to the limiting block 211;

[0061] The limiting square hole 131 is provided on the second positioning block 13, and each limiting square block 211 is in close contact with the inner wall of the limiting square hole 131;

[0062] Through the limiting effect of the limiting block 211 and the limiting square hole 131, the direction of the bending axis of the upper end of the first steel bar 21 is initially limited, thereby making it easier to connect the second steel bar 22 that cooperates with it on one side.

[0063] like Figure 1 to Figure 3 and Figure 5 As shown, a plurality of first engaging grooves 121 are all provided on the upper side of the first engaging block 12, a plurality of engaging blocks 132 are all fixedly connected to the lower side of the second engaging block 13, and each engaging block 132 abuts against each first engaging groove 121 correspondingly;

[0064] A plurality of second clamping grooves 141 are disposed on the upper side of the base 14 , and each clamping block 132 abuts against each second clamping groove 141 ;

[0065] When the height of the plywood column 11 matches that of the space to be installed, the second clamping block 13 and the lower base 14 can be mutually engaged and glued to improve the overall stability of the plywood column 11 after installation. However, when the height of the plywood column 11 is much different from the height of the space to be installed, a multi-section plywood column 11 can be used, and the second clamping block 13 and the first clamping block 12 can be mutually engaged and glued to perform multi-section plywood column 11 connection. Because the compressive strength of the steel bar itself is related to its own material, diameter, cross-sectional area, and length, the first steel bar 21 and the second steel bar 22 have the same diameter and cross-sectional area and are maintained at a shorter length, which can effectively improve the overall compressive strength of the plywood column 11.

[0066] Preferably, the length and width of the glued wood column 11 are set to 150mm*150mm, the height is set to 1000mm, the sizes of the first steel bar 21 and the second steel bar 22 are set to 10mm, 12mm, and 14mm for testing, and then a resistance strain gauge with a gauge length of 50mm is pasted on the central section of the glued wood column 11, and then the load test is performed on the glued wood column 11;

[0067] According to experimental data, the ultimate bearing capacity of the glued laminated timber column 11 with built-in 10mm diameter steel bars is most significantly improved compared with the pure glued laminated timber column 11. Therefore, this solution uses 10mm diameter steel bars to improve the overall strength of the glued laminated timber column 11, which not only reduces the procurement cost and construction cost, but also improves the overall strength of the glued laminated timber column 11.

[0068] like Figure 1 to Figure 3 and Figure 5As shown, the support groove 122 is provided on the lower side of the first positioning block 12;

[0069] The support groove 122 is used to avoid the part of the first steel bar 21 and each second steel bar 22 suspended in the air on the upper end of the glued wood column 11. It can not only play a certain limiting role on this part of the first steel bar 21 and each second steel bar 22, but also prevent the first blocking block 12 from interfering with the part of the first steel bar 21 and each second steel bar 22 suspended in the air on the upper end of the glued wood column 11.

[0070] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
