Description

A reorganized bamboo beam-column node mortise and tenon connection structure

Technical Field

The utility model belongs to the technical field of structural construction and installation nodes, and specifically relates to a reorganized bamboo beam-column node mortise and tenon connection structure.

Background Art

As an environmentally friendly renewable resource with abundant quantity and excellent performance, bamboo has recently attracted wide attention from scholars. Reconstructed bamboo is a green high-strength bamboo-based composite material made from raw bamboo as the base material, which is processed through a variety of processing techniques such as splitting, bamboo slice debonding, low-temperature drying, assembling along the grain, hot pressing (cold pressing) gluing, etc. It has excellent and stable performance, and has the advantages of high strength, good toughness, strong weather resistance, excellent flame retardancy, and low carbon and environmental protection. It can meet the various performance requirements of modern structures for building materials. Therefore, the component structures made of reconstructed bamboo are gradually being studied and used in the construction industry.

If we want to develop a complete reconstructed bamboo system, the research on reconstructed bamboo components is essential, but more importantly, we need to overcome the problems of its integrity and the connection of beam-column nodes. Since my country's research on bamboo materials is still late and relevant experience is insufficient, a set of reliable reconstructed bamboo beam-column node connection models has not yet been formed. By proposing a reconstructed bamboo beam-column node model and combining the traditional mortise and tenon connection form with steel filler plates, while absorbing the friction energy dissipation advantages of the mortise and tenon connection, the traditional connection tenons are easy to pull out and break, and the mortise mouth is easy to damage. The problem is solved, forming an effective node connection form with a certain seismic effect, which is of great significance to the development of the reconstructed bamboo structure system and its promotion in seismic fortification areas.

The utility model patent with application number 201620452755.X discloses "a reorganized bamboo frame beam-column mortise and tenon connection node", which is specifically: make a mortise groove at the connection of the reorganized bamboo frame beam, make a tenon at the corresponding connection of the mortise groove of the reorganized bamboo frame column, and then reserve corresponding bamboo pin holes at the designated positions of the reorganized bamboo frame beam and column; the prefabricated components are assembled on site, and after the reorganized bamboo frame column is connected to the base, the two ends of the reorganized bamboo frame beam are placed on the corresponding positions of the reorganized bamboo frame column, and then the bamboo pins are inserted into the holes reserved for the reorganized bamboo frame beam and column, so that the beam and column are tightly buckled for good force transmission. However, the model does not use internal filling steel plates, the tenon strength problem has never been improved, and the mortise is too weakened, which is very easy to damage the mortise during use, resulting in overall failure of the structure.

The utility model patent with patent application number 201320112104.2 discloses "a beam-column node connection of a reorganized bamboo frame structure"; specifically: two notches are left at the end of the reorganized bamboo frame beam, the node plate and two metal plates are connected to the side of the reorganized bamboo frame column by bolts, epoxy resin is applied to the upper part of the metal connector, and the end notch of the reorganized bamboo frame beam is inserted into the metal connector on the side of the reorganized bamboo frame column to form a whole. This reorganized bamboo frame beam-column node connection form is safe and reliable, can transmit force well, and is relatively simple to construct and install. Although this model adds steel filler plates at both ends of the beam to improve the strength of the weak node compared to the previous model, it does not consider the problem of energy dissipation and shock absorption, and the beam end is close to the steel plate. The difference in stiffness can easily cause the beam end to be squeezed and damaged when the node is subjected to strong action, and there is no obvious advantage in using it in the earthquake-resistant fortification area; at the same time, since the bolts on one side connecting the steel connector and the reorganized bamboo column are located inside the node, this model also has a problem of fitting the beam end and the steel connector.

It can be found that if the current reconstructed bamboo node connection only adopts the mostly used steel filler plate, there will be a problem of damage to the reconstructed bamboo components when bearing load due to the connection point being too rigid, and it does not play the role of friction energy dissipation and shock reduction during earthquakes; at the same time, because only mortise and tenon joints are used, there are problems such as insufficient tenon strength, broken tenons, and pulled tenons, all of which will lead to overall destruction of the node when bearing load, which is not conducive to the promotion of the reconstructed bamboo system in earthquake-resistant fortification areas.

Utility Model Content

The utility model aims to provide a reorganized bamboo beam-column node mortise and tenon connection structure in response to the problems of broken tenons and pulled tenons in existing reorganized bamboo beam-column connection nodes under strong loads, as well as the damage of slots by squeezing of steel filling plates, by combining analysis of the performance characteristics of reorganized bamboo and steel materials.

In order to achieve the purpose of the utility model, the technical solution adopted is: a mortise and tenon connection structure of a reorganized bamboo beam-column node, comprising a reorganized bamboo column and a reorganized bamboo beam connected by mortise and tenon joints, and the mortise and tenon joints of the reorganized bamboo column and the reorganized bamboo beam are jointly embedded with an inner filling steel plate; a lower support for supporting the reorganized bamboo column and the reorganized bamboo beam is also fixed on the inner filling steel plate, and steel hoops are provided on the reorganized bamboo column and the reorganized bamboo beam, one end of the lower support is pressed against the reorganized bamboo column by the steel hoop, and the other end of the lower support is pressed against the reorganized bamboo beam.

Furthermore, the lower support is an angle steel.

Furthermore, a waist plate is fixed on the angle steel, and an opening for avoiding the waist plate is opened on the steel hoop.

Furthermore, the tenons on the reorganized bamboo columns or the tenons on the reorganized bamboo beams are dovetail tenons with sleeve shoulders.

Furthermore, the inclination angle of the tenon of the dovetail tenon with sleeve shoulder is 80°.

Furthermore, the mortise and tenon joints of the reconstructed bamboo columns and the reconstructed bamboo beams are provided with reinforcing bolts.

Furthermore, the steel sleeve and the lower support are fixed by bolts.

Furthermore, the inner filling steel plate includes two thin steel plates and a reconstructed bamboo plate fixed between the two thin steel plates, and the outer sides of the two thin steel plates are provided with a composite rubber layer.

The beneficial effects of the utility model are:

(1) The construction process is simple and easy to assemble. The restructured bamboo beams, restructured bamboo columns and steel connectors can all be prefabricated in the factory and then transported to the construction site for assembly. The assembly process only relies on high-strength bolts. The assembly is simple and convenient, avoiding wet operations and not requiring high requirements from construction workers. It can effectively improve construction efficiency and shorten the construction period.

(2) The structure has good energy dissipation performance and can be used in earthquake-resistant areas. Compared with ordinary rigid node connections, the semi-rigid mortise and tenon connection is adopted in the utility model, and the dovetail tenon with sleeve shoulder further increases the contact area with the mortise than the ordinary tenon, so that during a strong earthquake, a considerable part of the energy brought by the earthquake can be offset by the friction and compression between the mortise and the tenon. At the same time, under the action of the earthquake, the high-strength bolts can also dissipate part of the energy by sliding relative to the bolt holes on the inner filling steel plate and the steel hoop.

(3) Good structural integrity and reasonable force transmission. The reconstructed bamboo beams, reconstructed bamboo columns and steel connectors are easy to make accurately and simply assembled. They can be spliced together with high-strength bolts to form a tightly connected whole. At the same time, the steel sleeve is connected to the beam and column through the lower support to form a "sleeve effect", which further improves the overall stability of the beam-column node and avoids the sudden collapse of the overall structure after the node is damaged or the tenon is cut off. In addition, the lower support as a connector can well provide a part of the vertical bending stiffness to the node and enhance the vertical bending capacity of the node. By using the angle steel as the lower support, the waist plate on the angle steel increases the force transmission area at the lower end of the node, effectively dispersing the concentrated stress at the lower part of the beam-column node, so that the node can better transmit shear force and bending moment. Compared with the common node model that uses the steel filling plate in the vertical direction as the lower support, the utility model increases the force bearing area of the node because the two ends of the angle steel are close to the beam and column, which greatly reduces the extrusion damage of the internal filling steel plate to the reconstructed bamboo.

(4) The node has good stability and working performance under strong earthquakes. The tenon in the utility model adopts a dovetail tenon with a sleeve shoulder, with an inclination angle of 80 degrees. The inclined sides of the dovetail tenon with a sleeve shoulder provide friction energy dissipation capacity. Due to the unique "dovetail" shape, it can effectively solve the problem of the tenon being easy to pull out. The sleeve shoulder at the root of the dovetail tenon with a sleeve shoulder increases the tenon heel area and improves the tenon's anti-bending ability, and the internal filling steel plate further enhances the tenon strength.

The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples. It is to be understood that the specific implementation examples described herein are only used to explain the relevant content, rather than to limit the present invention.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

As shown in Figures 1 to 4, the utility model provides a reorganized bamboo beam-column node mortise and tenon connection structure, including a reorganized bamboo column 1 and a reorganized bamboo beam 2, a mortise 7 is opened on the reorganized bamboo column 1, and a tenon 6 matching the mortise 7 is arranged on the reorganized bamboo beam 2, or a mortise 7 is opened on the reorganized bamboo beam 2, and a tenon 6 matching the mortise 7 of the reorganized bamboo column 1 is arranged on it, and the tenon 6 is inserted into the mortise 7 to achieve a mortise and tenon connection between the reorganized bamboo column 1 and the reorganized bamboo beam 2; a vertical through groove 8 is opened in the mortise 7 on the reorganized bamboo column 1, and the length of the vertical through groove 8 is greater than the depth of the mortise 7 on the reorganized bamboo column 1; a transverse through groove 5 is opened in the tenon 6 on the reorganized bamboo beam 2, and the length of the transverse through groove 5 is greater than the length of the tenon 6 on the reorganized bamboo column 1. When the reorganized bamboo column 1 and the reorganized bamboo beam 2 are connected by mortise and tenon joints, the vertical through groove 8 and the horizontal through groove 5 form a corresponding insertion groove. At this time, an inner filling steel plate 9 is inserted into the vertical through groove 8 and the horizontal through groove 5, so that the inner filling steel plate 9 is embedded in the mortise and tenon joints of the reorganized bamboo column 1 and the reorganized bamboo beam 2, so that the connection node of the reorganized bamboo column 1 and the reorganized bamboo beam 2 forms a semi-rigid node.

When the reorganized bamboo column 1 and the reorganized bamboo beam 2 are connected by mortise and tenon joints, the reorganized bamboo column 1 and the reorganized bamboo beam 2 form a right angle, and a lower support is welded on the inner filling steel plate 9. The lower support is located in the right angle formed by the reorganized bamboo column 1 and the reorganized bamboo beam 2, and supports the reorganized bamboo column 1 and the reorganized bamboo beam 2, so that the mortise and tenon joint structure of the reorganized bamboo column 1 and the reorganized bamboo beam 2 is more stable.

The reorganized bamboo column 1 and the reorganized bamboo beam 2 are both provided with steel hoops 3, the steel hoops 3 on the reorganized bamboo column 1 are located at the lower end of the vertical through groove 8, and the steel hoops 3 on the reorganized bamboo beam 2 are located at the end of the transverse through groove 5 away from the reorganized bamboo column 1; at the same time, the steel hoops 3 hold the lower supports tightly on the reorganized bamboo column 1 and the reorganized bamboo beam 2 while holding the reorganized bamboo column 1 and the reorganized bamboo beam 2, which not only ensures that the lower supports support the reorganized bamboo column 1 and the reorganized bamboo beam 2, but also prevents the reorganized bamboo column 1 from cracking at the vertical through groove 8 and the reorganized bamboo beam 2 from cracking at the transverse through groove 5 by holding the reorganized bamboo column 1 and the reorganized bamboo beam 2, so that the structural strength of the node connection between the reorganized bamboo column 1 and the reorganized bamboo beam 2 is better.

The lower support is an angle steel 10, the horizontal part of the angle steel 10 is supported on the reorganized bamboo beam 2, and the vertical part of the angle steel 10 is supported on the reorganized bamboo column 1, and after the angle steel 10 is installed, the right angle of the angle steel 10 is inserted into the right angle formed by the reorganized bamboo column 1 and the reorganized bamboo beam 2. When the angle steel is set, the width of the horizontal part of the angle steel 10 is equal to the width of the reorganized bamboo beam 2, and the width of the vertical part of the angle steel 10 is equal to the width of the reorganized bamboo column 1, so that after the angle steel 10 is installed, it can not only make the mortise and tenon joints of the reorganized bamboo column 1 and the reorganized bamboo beam 2 smoother, but also enable it to evenly bear the vertical force transmitted from the mortise and tenon joints of the reorganized bamboo beam 2.

In the present invention, with regard to the selection of the widths of the two steel hoops 3, specifically, the width of the steel hoop 3 sleeved on the reorganized bamboo column 1 is equal to the length of the vertical portion of the angle steel 10, which can not only effectively connect the angle steel 10, but also bear a part of the force transmitted from the mortise and tenon connection ends of the reorganized bamboo beam 2 to share the pressure of the angle steel 10; the width of the steel hoop 3 sleeved on the reorganized bamboo column 1 can be 1.5 to 5 cm smaller than the width of the horizontal portion of the angle steel 10 to prevent the two steel hoops 3 from being squeezed.

A waist plate 11 is also fixed to the angle steel 10, and the waist plate 11 is welded and fixed to the angle steel 10. There can be one or more waist plates 11. When there are multiple waist plates 11, the multiple waist plates 11 are arranged at intervals along the width direction of the angle steel 10. When the steel hoop 3 is tightly hugged on the reorganized bamboo beam 2 or the reorganized bamboo column 1, the horizontal part of the angle steel 10 is pressed between the steel hoop 3 and the reorganized bamboo beam 2, and the vertical part of the angle steel 10 is pressed between the steel hoop 3 and the reorganized bamboo column 1. Therefore, in order to avoid the waist plate 11, an opening for avoiding the waist plate 11 is also opened on the steel hoop 3. When there are multiple waist plates 11, the width of the opening is adapted to the width occupied by the installation of multiple waist plates 11. When there is only one waist plate 11, the width of the opening is adapted to the thickness of the waist plate 11.

The tenon 6 on the reconstructed bamboo column 1 or the tenon 6 on the reconstructed bamboo beam 2 is a dovetail tenon with a shoulder, which further increases the contact area with the mortise 7 compared with the ordinary tenon 6, so that during a strong earthquake, a considerable part of the energy brought by the earthquake can be offset through the friction and compression between the mortise 7 and the tenon 6.

Therefore, the inclination angle of the dovetail tenon with sleeve shoulder is 80°, and the dovetail tenon with sleeve shoulder at this angle has better comprehensive bending and pulling resistance.

The mortise and tenon joints of the reorganized bamboo column 1 and the reorganized bamboo beam 2 are provided with reinforcing bolts 4. Specifically, corresponding bolt holes are provided on the mortise and tenon joint ends of the reorganized bamboo column 1, the mortise and tenon joint ends of the reorganized bamboo beam 2 and the inner filling steel plate 9, and the reinforcing bolts 4 are installed in the corresponding bolt holes. The mortise and tenon joints of the reorganized bamboo column 1 and the reorganized bamboo beam 2 are further reinforced by the reinforcing bolts 4. In the utility model, the number of the reinforcing bolts 4 can be selected according to actual needs.

The steel sleeve 3 and the lower support are fixed by bolts. Specifically, the vertical part of the angle steel 10 and the steel sleeve 3 on the sleeved reorganized bamboo column 1 are provided with corresponding bolt holes, and the horizontal part of the angle steel 10 and the steel sleeve 3 on the sleeved reorganized bamboo beam 2 are provided with corresponding bolt holes, so that the steel sleeve 3 and the vertical part of the angle steel 10 are fixed to the reorganized bamboo column 1 by bolts, and the steel sleeve 3 and the horizontal part of the angle steel 10 are fixed to the reorganized bamboo beam 2 by bolts. In the utility model, the number of bolts used to fix the horizontal part of the angle steel 10 and the vertical part of the angle steel 10 can be selected according to actual needs.

The inner filling steel plate 9 includes two thin steel plates and a reconstructed bamboo plate fixed between the two thin steel plates. The thin steel plate and the reconstructed bamboo plate can be bonded by applying epoxy resin. At the same time, the outer sides of the two thin steel plates have a composite rubber layer, which is a friction energy-absorbing composite rubber material, further improving the energy absorption capacity of the node.

During the actual construction process, the reorganized bamboo beams 2 and the reorganized bamboo columns 1 must first be processed in the factory according to the specified dimensions; a mortise 7 and a vertical through groove 8 for embedding the inner filling steel plate 9 are opened on the reorganized bamboo column 1; a tenon 6 is processed on the reorganized bamboo beam 2 so that the tenon 6 has an inclination angle of 80 degrees, and a transverse through groove 5 is excavated at a certain depth inside the beam from the tenon 6; a steel sleeve 3 corresponding to the size of the reorganized bamboo beam 2 and the reorganized bamboo column 1 is prepared, a notch corresponding to the length of the tenon 6 is processed at the lower right corner of the inner filling steel plate 9, and the angle steel 10 is installed in the notch and then welded to the inner filling steel plate 9; two triangular waist plates 11 supported in the inner corners of the angle steel 10 are connected by spot welding; finally, the bolt holes required for installation are pre-drilled on the reorganized bamboo beam 2, the reorganized bamboo column 1, the steel sleeve 3, and the angle steel 10.

First, the steel hoop 3 is respectively sleeved on the reorganized bamboo beam 2 and the reorganized bamboo column 1, and then the inner filling steel plate 9 is inserted into the transverse through groove 5 reserved in the reorganized bamboo beam 2, and the inner filling steel plate 9 is accurately aligned with the reorganized bamboo beam 2; the reorganized bamboo beam 2 embedded with the inner filling steel plate 9 is inserted into the mortise 7 on the reorganized bamboo column 1 from above the reorganized bamboo column 1, so that the bolt holes on the tenon 6, the bolt holes on the inner filling steel plate 9, and the bolt holes on the reorganized bamboo column 1 are accurately aligned, and finally the reinforcement bolts 4 are implanted in the corresponding bolt holes to connect the reorganized bamboo beam 2, the reorganized bamboo column 1, and the inner filling steel plate 9 to form a whole.

The processed angle steel 10 is installed in the right angle formed by the reorganized bamboo beam 2 and the reorganized bamboo column 1, and the steel hoops 3 are placed in corresponding positions respectively. The steel hoops 3 mounted on the reorganized bamboo beam 2 play a temporary fixing role for the angle steel 10 that has not been connected with bolts, which is convenient for construction; at the same time, the bolt holes on the steel hoops 3 mounted on the reorganized bamboo beam 2 correspond to the bolt holes on the horizontal part of the angle steel 10, and the bolt holes on the steel hoops 3 mounted on the reorganized bamboo column 1 correspond to the bolt holes on the vertical part of the angle steel 10. Finally, the vertical part of the angle steel 10 and the steel hoops 3 mounted on the reorganized bamboo column 1 are fixed to the reorganized bamboo column 1 by bolts, and the horizontal part of the angle steel 10 and the steel hoops 3 mounted on the reorganized bamboo beam 2 are fixed to the reorganized bamboo beam 2 by bolts, thereby providing additional vertical stiffness while further enhancing the integrity of the structure.

In the process of processing the steel hoop 3 of the utility model, it should be noted that the size of the steel hoop 3 should be larger than the size of the reorganized bamboo beam 2 and the reorganized bamboo column 1 itself plus the thickness of an angle steel 10, so as to provide a filling position for the angle steel 10 and the bolts; secondly, the size of the tenon 6 on the reorganized bamboo beam 2 can be slightly larger than the size of the mortise 7 on the reorganized bamboo column 1 to ensure the tightness of the node connection and prevent the end seam and the peripheral seam from affecting the hysteresis energy dissipation capacity of the node.
