Description

Technical Field

[0001] The present invention relates to a building floor slab mainly made of bamboo, belonging to the field of construction engineering, and specifically to a large-span one-way board unit made of a mixture of original bamboo and reconstructed bamboo, a composite floor slab and a construction method, especially a large-span prefabricated lightweight composite floor slab made of a mixture of original bamboo and reconstructed bamboo assembled with all bolts, and a method for connecting and assembling the components. Background Art

[0002] As a natural material, bamboo offers advantages over other building materials, such as high strength, durability, low cost, and excellent thermal insulation. It can effectively meet structural and economic requirements. my country boasts abundant bamboo resources, and their rational development plays a significant role in protecting the ecological environment and achieving sustainable development in the construction industry. Research on bamboo has rapidly advanced in recent years, with the physical and mechanical properties of both raw bamboo and modified engineered bamboo receiving widespread attention. However, due to stereotypes surrounding bamboo, its current applications are primarily focused on non-structural applications such as flooring, furniture, building formwork, landscaping, and decorative materials. Because the mechanical properties of raw bamboo vary significantly depending on species, age, growing environment, and region, its durability in structures is often challenging, making it rarely used as a structural component. This hinders the promotion and application of bamboo in building structures. While reconstructed bamboo eliminates most of the drawbacks of raw bamboo for structural components and offers greater engineering applicability, its high cost makes it less competitive in the market. Therefore, based on the reliability and economy of mechanical properties, original bamboo and reconstructed bamboo are combined, and the structural and component stress characteristics are considered to develop targeted composite components that mix the two. This has positive significance for promoting the industrial application of bamboo materials, promoting the process of building industrialization, and achieving green environmental protection, energy conservation and emission reduction.

[0003] Chinese patent 201910164533.6 discloses "a bamboo structure floor, including a main beam, a secondary beam and a structural layer, the secondary beam is arranged on the main beam, the secondary beam and the main beam are perpendicular to each other, and the structural layer is laid on the secondary beam. The structural layer is composed of a base plate, non-woven fabric, spacers and panels from bottom to top, the base plate, non-woven fabric, spacers and panels are relatively fixed by nails, and the base plate is in contact with the secondary beam; an insulation layer is provided between the spacers under the panels."

[0013] Furthermore, it also includes: lateral end plates and connecting end plates, which are arranged at the ends of the one-way plate units in the horizontal direction, and the two are connected and fixed by horizontal connecting pieces.

[0014] Furthermore, it also includes: a reinforcement member, which is fixedly arranged on the outer sides of the reconstituted bamboo bottom plate and the reconstituted bamboo top plate.

[0015] Furthermore, the horizontal support member is an angle steel with a bolt hole, and the vertical connecting member passes through the back of the horizontal angle steel.

[0016] Furthermore, the filling material is a lightweight desulfurized gypsum modified material.

[0017] Furthermore, the positioning member is a transverse partition assembly, and the upper and lower flanges of the transverse partition assembly are respectively connected to the reconstituted bamboo bottom plate and the reconstituted bamboo top plate by rivets.

[0018] Furthermore, a groove is left on the floor slab at the position of the lateral end plate, so that the outer side of the lateral end plate is flush with the side surface of the floor slab.

[0019] Furthermore, the reinforcement is a galvanized steel plate, and the galvanized steel plate is connected and fixed by self-tapping screws.

[0020] On the other hand, the present application also protects a floor slab composed of large-span original bamboo and reconstructed bamboo mixed one-way slab units assembled by full bolts according to one of the aforementioned methods.

[0021] Furthermore, at the connection between adjacent one-way slab units:

[0022] A connecting steel plate is provided on the upper surface, and a T-shaped cross-section steel is provided on the lower surface. One end of the vertical connecting piece is fixed to the outside of the connecting steel plate, and the other end is fixed to the outside of the T-shaped cross-section steel.

[0024] Furthermore, the connecting steel plate is arranged above the reconstituted bamboo top plate, the T-section steel is arranged below the reconstituted bamboo top plate, and arc-shaped stiffening plates are arranged at intervals on the T-section steel.

[0025] On the other hand, the present application also protects a construction method for a large-span mixed original bamboo and reconstructed bamboo one-way slab unit assembled by full bolts according to any one of the aforementioned methods, comprising the following steps:

[0026] S1: Arrange horizontal supports at intervals of 600mm in the horizontal direction, then lay the reconstructed bamboo floor on the horizontal supports, connect and fix the positioning pieces to the reconstructed bamboo floor, and pass the vertical connectors from bottom to top through the back of the horizontal supports and the reconstructed bamboo floor;

[0028] Compared with prior art, the advantages of the present invention are as follows:

[0029] (1) The main material of the floor slab is bamboo, which comes from nature and is locally sourced. The material price is low, and the original bamboo is used to the maximum extent, which reduces the processing cost and reduces CO2 emissions to achieve the goal of energy conservation and emission reduction. The panels produced are green and environmentally friendly, and are constructed by dry method on site, with little pollution to the environment. The installation process is simple and easy, the assembly quality is easy to control, and the market competitiveness is strong.

[0030] (2) The present invention uses bamboo to make holes and bear the tension on the board. On the one hand, the hollowing out in the middle reduces the weight of the floor slab. On the other hand, the holes can also serve as pipeline channels without the need for additional holes, which reduces the process and the cost of component manufacturing. The construction is convenient and quick.

[0031] (3) The lightweight desulfurized gypsum modified material used for the filling has good performance. It is an industrial waste and its recycling is beneficial to the environment. While improving the durability of the bamboo, it also ensures the sound insulation, heat preservation, and thermal insulation properties of the floor. 1% glass fiber is added to further enhance the gypsum's resistance to brittle fracture. The angle steel with bolt holes at the bottom of the board can also serve as a ceiling bracket.

[0032] (4) The floor slabs are connected by full bolts, which are easy to assemble and disassemble. The technical requirements for workers are low. All components are prefabricated in the factory and assembled on site, meeting the requirements of prefabricated buildings. In addition, all components can be reused, which is in line with the development needs of a resource-saving and environmentally friendly society. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings 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 making creative efforts shall fall within the scope of protection of the present invention.

[0043] This invention combines the advantages of both raw and reconstructed bamboo, leveraging their strengths to overcome their weaknesses. This invention proposes a fully bolted, long-span, mixed-use, one-way panel unit that can be assembled into a floor slab. To ensure effective synergy between the upper and lower layers of raw bamboo, a matching crossbar assembly is added. This assembly is connected to the angle steel and upper and lower reconstructed bamboo panels via rivets to enhance the floor's integrity, ensuring synergy between components, better meeting the fundamental assumption of infinite in-plane stiffness, and further improving the floor's flexural rigidity. The specific solution is as follows:

[0044] A large-span one-way slab unit made of mixed original bamboo and reconstructed bamboo assembled with all bolts, comprising:

[0045] Horizontal support members, the horizontal support members are arranged at intervals;

[0046] A reconstructed bamboo bottom plate 3, wherein the reconstructed bamboo bottom plate 3 is arranged on the horizontal support member;

[0047] A positioning member, wherein a hole is provided on the web of the positioning member, and the positioning member is arranged on the reconstituted bamboo bottom plate 3;

[0048] Vertical connecting members, the vertical connecting members vertically passing through the horizontal supporting members, the reconstituted bamboo bottom plate 3 and the positioning members, extending upward through the reconstituted bamboo top plate 10 and then being fixed, with multiple vertical connecting members being arranged at intervals;

[0049] Double-layer raw bamboo 5, the upper and lower layers of the raw bamboo 5 are horizontally passed through the holes and arranged in the non-enclosed space formed by the vertical connecting member and the positioning member;

[0050] A filling material 9 is provided, wherein the filling material 9 is filled in the non-enclosed space.

[0051] The horizontal supports can be horizontal angle steels 2 with bolt holes. These are unequal angle steels with a spacing of 600 mm. The unequal angle steels are commercially available Q235B grade steel with specifications of L63×40×5. The angle steels are provided with bolt holes with a diameter of 10 mm, which can assist in connecting the ceiling connectors.

[0052] The reconstituted bamboo bottom plate 3 and the reconstituted bamboo top plate 10 are prefabricated in a factory and have a thickness of 10 mm. The length and width thereof are determined according to the specific conditions of the project.

[0053] The raw bamboo 5 is hand-selected, preferably with a diameter of 80mm to 100mm, from the same origin, batch, and species, ensuring similar cross-sectional dimensions and physical and mechanical properties. The raw bamboo is knotted using specialized tools to create internal cavities, which can be used for pipeline insertion and reduce the weight of the floor slab.

[0054] The original bamboo 5 is composed of two layers, one above the other. The positioning members are transverse spacers 16, located above the horizontal supports, for positioning and mounting the original bamboo 5. The upper and lower flanges of the transverse spacers 16 are connected to the reconstructed bamboo bottom plate 3 and the reconstructed bamboo top plate 10 via rivets 17. The transverse spacers 16 ensure that the two layers of original bamboo 5 can effectively coordinate their loads, enhancing the integrity of the floor slab and ensuring coordinated loads among the various components. This better meets the fundamental assumption of infinite in-plane stiffness for the floor slab and further improves the floor slab's bending stiffness.

[0055] In an embodiment of the present application, it further includes: a lateral end plate 8 and a connecting end plate 7, which are arranged at the ends of the one-way plate unit in the horizontal direction, and the two are connected and fixed by a horizontal connecting piece.

[0056] In another embodiment of the present application, the vertical connectors are long bolts with nuts (4) or long double-nut screws (15). Slots are provided in the floor slab at the locations of the lateral end panels (8), allowing the outer sides of the lateral end panels (8) to be flush with the sides of the floor slab. The fully bolted, one-way slab units, comprised of a mix of raw and reconstructed bamboo, located in the middle of the floor slab, can be assembled using long bolts with nuts (4). However, given that the ends of the floor slabs need to be connected to welded I-section steel beams (14), the long double-nut screws (15) at the ends of the floor slabs need to be replaced with the long double-nut screws (4) to facilitate connection to the steel beams (14).

[0057] In the embodiments of the present application, the structures of the one-way slab units preferably located in the middle and at the ends of the floor slab differ. The middle one-way slab units can adopt the aforementioned structure, while the end one-way slab units also include reinforcements fixedly located on the outside of the reconstituted bamboo bottom plate 3 and the reconstituted bamboo top plate 10. The reinforcements can be 1mm thick galvanized steel plates 12, with a length equal to the horizontal length of the one-way slab unit and a width approximately 50mm greater than the width of the steel beam connected to it at the lower end. The galvanized steel plates 12 are connected and fixed with self-tapping screws 13. As can be seen, the structure of the end portions of the one-way slab units is not much different from that of the middle portion, with the reinforcements added only to prevent localized strength deficiencies at the ends and to improve their wear resistance.

[0058] Filler material 9 can be a modified lightweight desulfurized gypsum material. This material is made from industrial waste desulfurized gypsum, modified with properties and incorporating lightweight glass microspheres or foaming technology. 1% glass fiber is also incorporated to improve resistance to brittle fracture. This material exhibits excellent thermal insulation, fire resistance, and sound insulation properties. Filling the pores formed by the upper and lower reconstructed bamboo panels and the original bamboo improves the durability of the original bamboo while also enhancing the sound insulation, thermal insulation, and heat insulation properties of the floor.

[0059] The steel plates, long screws, bolts, self-tapping screws and rivets are all made of standard specifications available on the market, and the cross-sectional dimensions, strength grades, performance requirements, etc. are determined according to specific circumstances.

[0060] In this application, the original bamboo and reconstructed bamboo mixed one-way board units assembled with full bolts can be spliced ​​and assembled into floor slabs. The specific scheme is as follows:

[0061] A floor slab is constructed from the aforementioned one-way slab units, a combination of original and reconstructed bamboo, assembled using full bolts. Given the large span of the floor slab, the existing one-way slab units may not be long enough in the longitudinal direction, necessitating extensions along the length of the slab. Furthermore, the connection reliability between the extended slabs needs to be further improved. During assembly, the following structure is provided at the junction of adjacent one-way slab units:

[0062] A connecting steel plate 18 is provided on the upper surface, and a T-shaped section steel 19 is provided on the lower surface. Both ends of the vertical connecting member are respectively fixed through the connecting steel plate 18 and the T-shaped section steel 19;

[0063] The connecting steel plate 18, constructed from 10mm thick steel, is installed above the reconstituted bamboo top panel 10. The T-section steel plate 19, welded from 10mm thick steel plates, is installed beneath the reconstituted bamboo bottom panel 3. They are connected by long double-nut screws 4. Expansive mortar 21 is poured into the gap between the two panels to ensure a reliable and effective joint. Curved stiffeners 20 are symmetrically arranged at 100mm intervals along the length of the T-section steel plate 19 to further enhance connection reliability and load-bearing capacity.

[0064] The following describes embodiments of the present application with reference to the accompanying drawings.

[0065] Example 1: Large span fully bolted bamboo composite floor ( Figure 1-7 )

[0066] See also Figures 1 to 7The long-span, fully bolted bamboo composite floor proposed in this invention comprises horizontal angle steels 2 with bolt holes 1 arranged at 600mm intervals along the longitudinal direction of the floor. A reconstructed bamboo base plate 3 is laid on the angle steels 2. Long screws 4 with nuts extend upward through the back of the horizontal angle steels 2 and the reconstructed bamboo base plate 3. Original bamboo 5 is arranged horizontally between the long screws 4 with nuts. Bolts 6 connect the end plates 7 to the lateral end plates 8. The remaining portion of the floor is filled with a lightweight desulfurized gypsum modified material 9 using an installation template. A reconstructed bamboo top plate 10 is laid on the top surface. The long screws 4 with nuts extend through the reconstructed bamboo top plate 10 and are secured with nuts 11 and compression washers. Preferably, it also includes a transverse spacer assembly 16, rivets 17, connecting steel plates 18, welded T-section steel 19, curved stiffeners 20, and expansion mortar 21. The diaphragm assembly 16 is installed at the location of the horizontal angle steel 2. The diaphragm assembly 16 with holes on the web is used to position and install the original bamboo, while also enhancing the integrity of the floor and the coordinated force of each component. The upper and lower flanges of the diaphragm assembly 16 are connected to the reconstructed bamboo bottom plate 3 and the reconstructed bamboo top plate 10 through rivets 17. Figure 2 , on the side of the one-way plate unit. Preferably, it also includes an end plate 8 with bolt holes for splicing between one-way plate units. The bottom angle steel of the plate is welded to a small end plate and connected to the side end plate 8 of the one-way plate unit through bolts 6. Figure 3 , at the end of the one-way plate unit. Preferably, a double-nut long screw 15 is used to replace the long screw with a nut 4 to facilitate connection with the I-shaped steel beam 14. Figure 7 At the ends of the two plates, the one-way plate unit is longitudinally extended using double-nut long screws 15, connecting steel plates 18, welded T-section steel 19, arc-shaped stiffening plates 20 and expansion mortar 21.

[0067] This application is based on the consideration of the stress characteristics of floor slabs in house construction, the connection process and stress reliability of the connection between prefabricated floor slab units, the connection between prefabricated floor slabs and beams, and the longitudinal extension of prefabricated floor slab units during the assembly process, combined with the stress characteristics of original bamboo and reconstructed bamboo, supplemented by long bolts and other connecting parts, to achieve the research and development of bamboo prefabricated composite floor slabs and their rapid and reliable connection with the main structure, which has positive significance for promoting the industrial application of bamboo materials and promoting their engineering production.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
