Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building structure, in particular to a thin -walled H -shaped steel bamboo or steel wood combined floor connecting joint. BACKGROUND

[0002] The currently common building floor forms are mainly reinforced concrete floor and steel-concrete composite floor, which have the defects of large self weight, long construction period, difficult installation and transportation. The heavy floor components have caused very serious harm to people's life safety in the past earthquakes.

[0003] Bamboo and wood both have the advantages of light self weight and high strength, and are very suitable for structural materials; steel has high strength, large rigidity and convenient processing, and is an ideal building structural material. If the two are organically combined, the required bearing capacity and rigidity of the building floor can be obtained with less material consumption, so that the weight of the floor system is greatly reduced, thereby the building has outstanding performance of protecting life safety in the earthquake process, and the cost is reduced.

[0004] The floor system in modern wood structure generally adopts setting up dimensional lumber with small spacing and laying oriented strand board on the dimensional lumber; the traditional steel wood composite floor generally adopts thin-walled steel to make floor beam and lays oriented strand board on the floor beam. The above floor systems have large site operation amount, high material consumption and high cost.

[0005] Steel, bamboo and wood are all ideal building structural materials, and each has different aspects of stress performance characteristics, so seeking a more reasonable combination between the two materials and giving full play to the performance advantages of the two materials will promote the benign development of the building industry.

[0006] The existing Chinese patent application No. CN201811195749.0 discloses a thin-walled I-shaped steel light wood composite structure load-bearing insulation wall panel-floor joint. The thin-walled I-shaped steel light wood composite structure load-bearing insulation wall panels of the upper and lower floors are connected with the thin-walled I-shaped steel light wood composite structure sound insulation floor by the bottom vertical connecting notch, the top vertical connecting notch and nails. The effect and advantages of the present application are that the overall rigidity is large, the out-of-plane buckling of the wall panel can be effectively prevented, the overall instability of the structure can be avoided, and the safety performance of the light steel residence can be significantly improved. The industrialization level is significantly improved, the load-bearing and insulation integrated wall panel is produced and processed in a large part and in an integrated manner. The insulation and construction are considered, the heat bridge is cut off, and the construction is also simple and convenient.

[0007] The above floor connecting joint structure is complex, the construction period is long, and it is not conducive to site construction. UTILITY MODEL CONTENTS

[0036] like Figures 1-8 As shown, this utility model discloses a connection node for a thin-walled H-shaped steel-bamboo or steel-wood composite floor slab, including a steel-wood composite floor slab 1, an upper vertical wall 7, and a lower vertical wall 8. A connection part 2 is formed on one side of the steel-wood composite floor slab 1, and the connection part 2 is a stepped groove recessed from the top surface to the bottom surface. The stepped groove is provided with a through connection hole 3 extending along the thickness direction of the steel-wood composite floor slab 1. However, this patent is not limited to this. As long as a connection part 2 with a through connection hole 3 is formed on at least one side of the steel-wood composite floor slab 1, the specific number and position of the connection parts 2 can be reasonably designed according to the actual installation situation. Taking the steel-wood composite floor slab 1 as a cuboid as an example, when the steel-wood composite floor slab is located on the outermost side, that is, it is only connected to the upper and lower vertical walls and is no longer connected to other steel-wood composite floor slabs, the side of the steel-wood composite floor slab connected to the upper and lower vertical walls can simply be formed as a common end face as a connection part 2; if the steel-wood composite floor slab is located in the middle, that is, all four sides of the steel-wood composite floor slab need to be connected to other steel-wood composite floor slabs, then all four sides of the steel-wood composite floor slab need to form a connection part 2 to achieve matching connection with other steel-wood composite floor slabs.

[0037] The structure of the floor slab located in the middle is described in detail below.

[0038] Each steel-wood composite floor slab 1 comprises a first connecting portion 4 and a second connecting portion 5 at two ends, and the first connecting portion 4 of one steel-wood composite floor slab 1 can be connected with the second connecting portion 5 of another steel-wood composite floor slab 1. By forming the connecting portions 2 at the opposite ends of the steel-wood composite floor slab 1 to be connected with each other, the connection between the steel-wood composite floor slabs is facilitated. Specifically, the first connecting portion 4 and the second connecting portion 5 are formed at the opposite ends of the steel-wood composite floor slab 1, and the first connecting portion 4 of one steel-wood composite floor slab 1 can be connected with the second connecting portion 5 of another steel-wood composite floor slab 1, which not only realizes the quick connection between the steel-wood composite floor slabs 1, but also realizes the batch production of the steel-wood composite floor slabs 1, i.e. only one mold needs to be designed when the floor slabs are produced, which saves the production cost and the production process, and makes the connecting portion 2 of the steel-wood composite floor slab be able to be quickly connected with the connecting portion 2 of the adjacent steel-wood composite floor slab. The first connecting portion 4 and the second connecting portion 5 are both formed with the through connecting holes 3, and the through connecting holes 3 of the first connecting portion 4 and the second connecting portion 5 are symmetrically arranged about the center line of the steel-wood composite floor slab 1.

[0039] In particular, in one embodiment of the present patent, the first connecting portion 4 and the second connecting portion 5 are formed as mutually matching stepped grooves. Specifically, the first end of the steel-wood composite floor slab 1 is formed with a first stepped groove recessed from the bottom surface of the steel-wood composite floor slab 1 towards the top surface, so as to form the first connecting portion 4 thinner than the thickness of the steel-wood composite floor slab 1; and the second end of the steel-wood composite floor slab 1 is formed with a second stepped groove recessed from the top surface of the steel-wood composite floor slab 1 towards the bottom surface, so as to form the second connecting portion 5 thinner than the thickness of the steel-wood composite floor slab 1. By the first stepped groove of one steel-wood composite floor slab 1 being overlapped with the second stepped groove of the adjacent another steel-wood composite floor slab 1, the two steel-wood composite floor slabs 1 can be quickly connected, and the second stepped groove of the adjacent another steel-wood composite floor slab 1 can also be overlapped with the first stepped groove of the adjacent again another steel-wood composite floor slab 1, so as to realize the quick connection of multiple steel-wood composite floor slabs 1. The first stepped groove and the second stepped groove are both formed with the through connecting holes 3, and the through connecting holes 3 on the first stepped groove and the second stepped groove are symmetrically arranged about the center line of the steel-wood composite floor slab 1.

[0040] The sum of the thicknesses of the first connecting portion 4 and the second connecting portion 5 is equal to the thickness of the steel-wood composite floor slab 1, so that there is no height difference between the connecting portions 2 of the two steel-wood composite floor slabs connected with each other and the steel-wood composite floor slab 1, thus making the overall appearance of the floor slabs beautiful, and making the design and forming of the first connecting portion 4 and the second connecting portion 5 of the steel-wood composite floor slab simpler. More preferably, in order to ensure the strength of the first connecting portion 4 and the second connecting portion 5, the thicknesses of the first connecting portion 4 and the second connecting portion 5 are both half of the thickness of the steel-wood composite floor slab 1.

[0041] In another embodiment of the present patent, the first connecting part 4 and the second connecting part 5 are formed as a mortise and tenon structure that match each other. Specifically, the first end of the steel-wood composite floor slab 1 is formed with a mortise extending inwardly from the end surface of the first end as the first connecting part 4; and the second end of the steel-wood composite floor slab 1 is formed with a tenon that matches the mortise as the second connecting part 5. In this embodiment, by forming the mortise on the end surface of the first end of the steel-wood composite floor slab 1 and forming the tenon on the second end of the steel-wood composite floor slab 1, when the steel-wood composite floor slabs 1 are connected, the mortise of one steel-wood composite floor slab 1 matches the tenon of the adjacent steel-wood composite floor slab 1, and the tenon of the adjacent steel-wood composite floor slab 1 matches the mortise of the steel-wood composite floor slab 1 adjacent thereto, so that the matching connection of multiple steel-wood composite floor slabs 1 can also be achieved. The shape of the joint surface of the mortise and the tenon is not limited here, as long as the shape of the joint surface of the mortise and the tenon can complementarily match each other. However, the present patent is not limited to the above two embodiments, and other structures of the first connecting part 4 and the second connecting part 5 can also be used, as long as the quick matching connection of the first connecting part 4 and the second connecting part 5 can be achieved.

[0042] The width of the first connecting part 4 and the second connecting part 5 is not less than the width of the through connecting hole 3. This allows a complete through connecting hole 3 to be formed on the first connecting part 4 and the second connecting part 5, respectively, so that the connecting pin is sequentially inserted through the through connecting holes 3 on the first connecting part 4 and the second connecting part 5, so that the connecting part of the two steel-wood composite floor slabs is fixed.

[0043] Further, a protective sleeve is arranged in the through connecting hole 3. This allows the connecting pin 6 to only contact the protective sleeve of the through connecting hole 3 when fixing the connecting part of the two steel-wood composite floor slabs, and the protective sleeve limits the action of the connecting pin 6 to apply force to the through connecting hole 3. The protective sleeve further protects the through connecting hole 3, i.e., avoids cracks or direct breakage of the through connecting hole 3 due to the connecting pin 6 directly applying force to the inner peripheral wall of the through connecting hole 3. The protective sleeve can be a rigid sleeve such as a steel sleeve.

[0044] The connecting surface of the upper vertical wall 7 and the lower vertical wall 8 is provided with a pin hole 9 corresponding to the through connecting hole 3, the connecting pin 6 is inserted through the aligned through connecting hole 3 and pin hole 9, the connecting part 2 of the steel-wood composite floor is arranged between the upper vertical wall 7 and the lower vertical wall 8, the through connecting hole 3 of the connecting part 2 is penetrated by the connecting pin 6, and the two ends of the connecting pin 6 are inserted into the pin holes 9 of the upper vertical wall 7 and the lower vertical wall 8, respectively, so that the steel-wood composite floor can be horizontally installed between the upper vertical wall 7 and the lower vertical wall 8. The connecting pin 3 not only fixes the connecting part of the two steel-wood composite floors, but also connects the upper vertical wall 7 and the lower vertical wall 8. In order to increase the anti-seismic and load reduction of the steel-wood composite floor connecting structure, the connecting pin 6 has an elastic outer surface, and the connecting pin 6 is a spindle-shaped structure with small ends and a drum-shaped middle part.

[0045] The steel-wood composite floor comprises two parallel wood plates 1.1, an H-shaped steel 1.3 arranged between the wood plates 1.1, and wood strips 1.4 arranged between the wood plates 1.1 and along the periphery of the wood plates 1.1, wherein the wood plates 1.1 are fixedly connected with the H-shaped steel 1.3 and the wood strips 1.4, and the wood plates are bamboo or wood-based plates.

[0046] Embodiment one:

[0047] The wood strips 1.4 are connected with the wood plates 1.1 by fasteners 1.2, and the fasteners 1.2 can be rivets or screws.

[0048] Embodiment two:

[0049] The H-shaped steel 1.3 is connected with the wood plates 1.1 by fasteners 1.2 or adhesives, and the fasteners 1.2 can be rivets or screws.

[0052] The above-described embodiments are only used to describe the preferred embodiments of the present application, and are not used to limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements of the technical solutions of the present application made by those skilled in the art should fall within the protection scope of the present application.
