Technical Field

[0001] The present invention relates to the technical field of construction engineering, and in particular to a connection structure between an assembled steel frame exterior wall and a floor slab. Background Art

[0002] The connection between steel-framed exterior walls and floor slabs is a common method in the construction field, so it is necessary to take into account structural safety, seismic performance and construction convenience. In particular, in the scenario of non-load-bearing exterior walls of buildings, prefabricated structural connections are generally used, which have the advantages of flexible construction and detachable adjustment. In actual applications, when affected by external forces (such as earthquakes and vibrations from large equipment drills), there may be vibration fluctuations between the exterior walls and floor slabs. Existing prefabricated connection structures usually adopt a direct assembly method and do not have a shock-absorbing structure for the connection structure. Under the influence of vibration, the structure may become loose, such as loose bolts, which is not conducive to improving the tightness of the connection structure and the long-term service life. Therefore, it is particularly important to buffer seismic forces and improve seismic performance. Summary of the Invention

[0016] The moving member reciprocates in the angle steel under the action of the action force and the reaction force.

[0017] In some embodiments, the angle steel is provided with a mounting groove for mounting the shock absorbing assembly, and a slide groove connected to the mounting groove, and the movable member is provided with a guide block, which slides in the slide groove to guide the movable member to move in the mounting groove.

[0018] In some embodiments, the floor slab has embedded parts, the embedded parts are provided with positioning columns, the angle steel is provided with positioning holes and connecting holes, and when the positioning columns are inserted into the positioning holes, the ends of the second bolt members are exposed to the connecting holes.

[0019] In some embodiments, the embedded part has a recess, the positioning column is disposed in the recess, and when the angle steel abuts against the recess, the end surface of the angle steel is flush with the end surface of the floor slab.

[0020] In some embodiments, the embedded part includes a steel plate and a tripod connected to each other, the second bolt member is connected to the steel plate, and an end of the second bolt member is arranged on a surface of the steel plate.

[0023] In some embodiments, the connecting seat is symmetrically provided with a steel frame, the steel frame is provided with a guide shaft, the end of the first bolt member is provided with a guide groove, and the first bolt member is inserted into the guide shaft through the guide groove to lock the position of the embedded first bolt member.

[0024] In some embodiments, a plurality of notches are provided on the peripheral side surface of the first bolt member, and when the first bolt member is embedded in the exterior wall panel, the notches are sealed and embedded.

[0025] Compared with the prior art, the connection structure of the assembled steel frame exterior wall and the floor slab of the present invention has the following advantages:

DETAILED DESCRIPTION

[0036] To make the purpose, 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.

[0037] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0038] like Figure 1 、 Figure 2 As shown, the present invention relates to a connection structure of an assembled steel frame exterior wall and a floor slab, which is used to connect an exterior wall panel 1 and a floor slab 2. The exterior wall panel 1 is such as a steel frame exterior wall, and the floor slab 2 is such as a concrete floor slab 2 or a steel structure floor slab 2. It is suitable for connecting and assembling non-load-bearing exterior walls, concrete floor slabs 2 or steel structure floor slabs 2, and is simple to assemble and easy to construct.

[0039] It should be noted that the exterior wall panel 1 consists of a steel frame, an insulating core material 11, and a cladding layer. The steel frame is made of high-strength steel, such as C-section steel, which provides load-bearing and bending resistance, ensuring overall rigidity and dimensional stability. The insulating core material 11 is typically made of high-performance insulating materials such as polystyrene (EPS), extruded polystyrene (XPS), or rock wool, providing primary insulation, sound insulation, noise reduction, and fire separation. The insulating core material 11 can be incorporated into the steel frame. The cladding layer is typically made of fiber cement board or galvanized steel sheet 211. Fiber cement board has a Class A fire rating, excellent weather resistance, and high strength, and can be used directly as exterior or interior wall cladding or as a base layer. Galvanized steel sheet 211 is commonly used in industrial buildings, providing additional protection and strength, and is sometimes profiled for enhanced rigidity. The floor slab 2 is composed of steel bars, concrete, and any necessary additional layers, providing a strong overall structure. The assembled floor slab 2 is assembled on-site from prefabricated components in the factory, with high construction efficiency, which is in line with the trend of assembled buildings. The floor slab 2 of this embodiment is preferably a prefabricated reinforced concrete composite floor slab 2. The prefabricated steel bars in the floor slab 2 are stacked in an A-shape, and the overall firmness is more reliable.

[0040] The present invention will be further described in detail below with reference to the accompanying drawings.

[0041] Figure 1 The following schematically shows the connection structure between the assembled steel frame exterior wall and the floor slab 2 according to one embodiment of the present invention (hereinafter referred to as "the connection structure"). Figure 3 As shown, the connection structure between the assembled steel frame exterior wall and the floor slab 2 includes an angle steel 3, a shock-absorbing assembly 4, a first bolt member 5 and a second bolt member 6.

[0042] Angle steel 3 adopts L-shaped right-angle bending steel structure, for the convenience of description, such as Figure 3 As shown, the angle steel 3 is divided into two parts, namely the first steel part 31 and the second steel part 32. The side end surface of the first steel part 31 is used to connect to the exterior wall panel 1, and the second steel part 32 is used to connect to the floor slab 2. The assembled connection is achieved through a bolt structure. The first steel part 31 and the second steel part 32 both have waist-shaped holes (long circular holes) for providing a bolt structure connection. The second steel part 32 can have two waist-shaped holes symmetrically arranged, and in the horizontal direction, the waist-shaped holes of the first steel part 31 and the second steel part 32 are staggered to avoid interference during connection. In this embodiment, the shock-absorbing element is set in the first steel part 31. Specifically, the shock-absorbing component 4 is exposed on the outer side of the first steel part 31.

[0043] like Figure 4As shown, the shock absorbing assembly 4 includes a first elastic member 41, a moving member 42, a second elastic member 43 and an abutment block 44. The first elastic member 41 and the second elastic member 43 are both springs, wherein the first steel portion 31 is provided with a mounting groove 311, and the mounting groove 311 is a groove structure recessed along the direction passing through the first steel portion 31. The shock absorbing assembly 4 can be set in the mounting groove 311, and the first elastic member 41 is connected to the inner wall of the mounting groove 311. The moving member 42 adopts a lightweight block structure and can reciprocate along the mounting groove 311. The two sides of the moving member 42 are respectively connected to the first elastic member 41 and the second elastic member 43. The abutment block 44 is connected through the end of the second elastic member 43, and the outer side surface of the abutment block 44 abuts against the exterior wall panel 1, for example, abuts against the steel frame of the exterior wall panel 1. Furthermore, in order to enable the moving part 42 to be stably and smoothly installed and moved in the preset direction, a connected slide groove 312 is provided on both sides of the installation groove 311. Correspondingly, a guide block 421 is provided on both sides of the moving part 42. The guide blocks 421 are symmetrically arranged, and the guide blocks 421 can slide and cooperate in the slide groove 312, so that the moving part 42 can be guided to move back and forth through the slide groove 312 and the slide groove 312, thereby improving stability.

[0044] When the exterior wall panel 1 is affected by an external force and generates a force on the angle steel 3, the force is transmitted to the first elastic member 41 through the abutment block 44, so that the movable member 42 moves along the installation groove 311, and the angle steel 3 also has a reaction force on the shock absorbing assembly 4. Under the action of the second elastic member 43, the movable member 42 receives the reaction force and moves in the opposite direction, thereby continuously moving back and forth, so that the movable member 42 moves and does work in the installation groove 311, so as to quickly consume the external force caused by the vibration and achieve the shock absorption effect. It can effectively reduce the vibration of the angle steel 3, so as to improve the seismic resistance of the connection structure, so that the angle steel 3 is not easy to loosen when connected by the bolt structure.

[0045] Of course, the shock-absorbing component 4 can also be set in the second steel part 32, so that the second steel part 32 can have a shock-absorbing effect after being connected to the floor 2. Since the angle steel 3 is subjected to a greater lateral vibration force from the exterior wall panel 1, this embodiment takes the setting in the first steel part 31 as an example.

[0046] like Figure 5 、 Figure 6As shown, the first steel portion 31 is connected to the exterior wall panel 1. In this embodiment, in order to improve the strength of the connection with the exterior wall panel 1, a connection seat 13 is provided at the bottom of the exterior wall panel 1. The first bolt member 5 can be pre-buried in the connection seat 13. The first bolt member 5 is specifically a straight rod structure with a thread, and after the first bolt member 5 is pre-buried, its end can extend out of the exterior wall panel 1. The extended portion has an external thread structure and can be fastened to the angle steel 3 through a gasket 7 and a nut 8. The connection seat 13 adopts an internal hollow closed frame structure, which is fixedly connected to the steel frame of the exterior wall panel 1, preferably by welding, and a first bent portion 131 is also provided on the connection seat 13. When the connection seat 13 is connected, the first bent portion 131 can extend into the steel frame of the exterior wall panel 1, which can effectively prevent leakage when the core material 11 is filled, and the sealing effect is better. In addition, in order to improve the supporting strength of the connecting seat 13, symmetrical steel frames 132 are provided on the inner walls on both sides of the connecting seat 13. The steel frames 132 are in the shape of a door and can be abutted against the bent inner wall of the connecting seat 13 for support. Support ribs 133 are provided on the inner side of the steel frame 132, which can further improve the supporting strength of the steel frame 132 and make the connecting seat 13 less likely to collapse.

[0047] Among them, this embodiment adopts the method of inserting and pre-embedding the first bolt member 5 to fix the first bolt member 5. Specifically, the first bolt member 5 is inserted and extended to the connecting seat 13 and then pre-embedded. In order to ensure the connection accuracy of the first bolt member 5 and avoid the situation of tilting after pre-embedding to affect the assembly effect, in this embodiment, Figure 7 As shown, a guide shaft 134 is provided on the inner side of one of the steel frames 132. The guide shaft 134 is specifically a columnar structure protruding from the steel frame 132. A guide groove 51 is provided at the end of the first bolt member 5. The size of the guide groove 51 is adapted to the guide shaft 134. After the first bolt member 5 is inserted into the connection seat 13, the guide shaft 134 cooperates with the guide groove 51 to complete the linear positioning of the first bolt member 5. It can be seen that the axis of the guide shaft 134 is aligned with the axis of the first bolt member 5. Therefore, after the first bolt member 5 is embedded, it can extend to the outside of the connection seat 13 with a more precise axis verticality, thereby improving assembly accuracy. After the first bolt member 5 is inserted, it can be fixedly connected to the connection seat 13 by welding, and the gap between the outside of the connection seat 13 and the hole of the first bolt member 5 can be sealed by welding.

[0048] Further, such as Figure 7As shown, since the core material 11 needs to be buried after the first bolt member 5 is fixed to the connecting seat 13, the first bolt member 5 needs to withstand a large gravity. In order to improve the supporting strength of the first bolt member 5 and avoid breakage, a support platform 135 is provided at the bottom of the connecting seat 13. The number of support platforms 135 is at least two. The support platform 135 is used to abut against the side surface of the first bolt member 5 to support the first bolt member 5. The support platform 135 has an integrally connected arc portion 1351 and a foot seat 1352. The foot seat 1352 can be fixedly connected to the bottom of the connecting platform and provide a suitable supporting height for the arc portion 1351. The arc portion 1351 adopts a curved plate structure of an arc, which can abut against and support the first bolt member 5, and the arc portion 1351 can surround part of the side surface of the first bolt member 5, while the remaining part of the first bolt member 5 and the arc portion 1351 are buried by the core material 11, which improves the supporting strength of the first bolt member 5 without affecting the fixing strength of the first bolt member 5.

[0049] Further, such as Figure 7 As shown, a plurality of notches 52 are provided on the peripheral side surface of the first bolt member 5, and the notches 52 are preferably V-shaped structures. When the first bolt member 5 is pre-buried in the connecting seat 13 or the exterior wall panel 1, the notches 52 are sealed and buried. The design of the notches 52 can improve the strength of the first bolt member 5 to a certain extent, and make the connection of the first bolt member 5 tighter after pre-buried, and the first bolt member 5 is not easily loosened by horizontal external forces.

[0050] In addition, if Figure 2 As shown, a second bending portion 14 is provided on the steel frame of the exterior wall panel 1, and the angle steel 3 can be connected to the lower side of the second bending portion 14. The second bending portion 14 can protect the first bolt 5 and the angle steel 3, and the second bending portion 14 is aligned with other embedded layers, for example, flush with the sand and stone building layer 22, which serves to mark the lowest height of the landfill.

[0051] like Figure 8 As shown, the second steel part 32 is detachably connected to the floor 2, specifically by a second bolt member 6. The second bolt member 6 is specifically a sleeve with an internal thread, which can be pre-buried in the floor 2, wherein the floor 2 has an embedded part 21, and the embedded part 21 connects the steel plate 211 and the tripod 212 to each other, which can be connected by welding. After the steel plate 211 and the tripod 212 are embedded in the floor 2, the surface of the steel plate 211 is flush with the floor 2, and a recess 213 is provided on the steel plate 211. The recess 213 is a groove structure on the steel plate 211, and its size is adapted to the second steel part 32. When the second steel part 32 abuts against the recess 213, the upper surface of the second steel part 32 is flush with the surface of the floor 2. In this way, the assembly accuracy of the angle steel 3 during installation can be identified. If there is a deviation, the installation position of the first steel part 31 can be appropriately adjusted.

[0052] Further, such as Figure 5 、 Figure 8 As shown, a positioning column 214 is provided on the steel plate 211, and the positioning column 214 is located in the recess 213, and the second steel part 32 is provided with a connecting hole 322 and a positioning hole 321. The connecting hole 322 is a waist-shaped hole on the angle steel 3, and the positioning hole 321 is adapted to the size of the positioning column 214. In comparison, the positioning hole 321 has a higher precision. The positioning column 214 can be inserted into the positioning hole 321, so that the second steel part 32 can be positioned according to the preset position, and then abutted against the side of the second steel part 32 through the recess 213. At this time, the position of the connecting hole 322 can be more accurately aligned with the port of the second bolt member 6. It should be noted that the second bolt member 6 is fixedly arranged in the steel plate 211, and the port of the second bolt member 6 can be exposed on the surface of the steel plate 211. When the second steel portion 32 is inserted and positioned with the positioning column 214 through the positioning hole 321, the port of the second bolt member 6 can be accurately exposed in the connecting hole 322. Then, the bolt with an external thread and the gasket 7 are inserted into the connecting hole 322 and threadedly connected with the second bolt member 6, so that the second steel portion 32 (angle steel 3) can be fastened to the floor slab 2.

[0053] The tripod 212 is mainly used to further support the steel plate 211 after pre-embedding. The tripod 212 is symmetrically connected on both sides of the steel plate 211. The bottom of the tripod 212 is a straight rod structure, and the bottom of the tripod 212 can abut against the A-shaped steel bar of the floor 2 to improve the overall supporting strength of the tripod 212.

[0054] In addition, if Figure 2 As shown, to prevent rigid contact between the exterior wall panels 1 and the floor slabs 2, an isolation layer 23 is provided between the exterior wall panels 1 and the floor slabs 2. This isolation layer 23 can be made of, for example, a rubber pad, polyethylene foam board, foamed silicone pad, or rock wool pad. Optionally, a fine stone concrete layer 24 is provided on top of the isolation layer 23. A weatherproof sealant layer 25 (such as silicone sealant) is filled in the outer gaps of the connection joints. A concrete counterslope or waterproofing membrane is provided at the bottom of the wall panels to prevent rainwater from seeping into the floor slabs 2. Furthermore, an internal fiber cement board 15 is provided on the steel frame of the exterior wall panels 1, extending up to the second bend 14. An external fiber cement board 26 is provided on the outer side of the floor slabs 2. Finally, the outer sides of the exterior wall panels 1 and the floor slabs 2 are covered by an insulation board layer 9. The insulation board layer 9 can be made of, for example, molded polystyrene foam board, vacuum insulation board, rock wool board, or air concrete board.

[0055] Construction process: first embed the embedded part 21 on the floor 2, then insert the second steel part 32 into the positioning column 214 through the positioning hole 321, and use the bolt and gasket 7 to connect the second bolt part 6 to fasten the second steel part 32 to the steel plate 211. At the same time, fix the first bolt part 5 on the connecting seat 13, and support the first bolt part 5 through the support platform 135, and then fill the core material 11 to embed the first bolt part 5. At this time, the first steel part 31 with the shock absorber assembly 4 installed is abutted against the connecting seat 13, and the end of the first bolt part 5 passes through the first bolt part 5, and then use the gasket 7 and nut 8 to fasten the first steel part 31 to the exterior wall panel 1 to complete the assembled connection, and then fill the sand and stone building layer 22 to the floor slab 2 to cover the second steel part 32. Subsequently, the isolation layer 23 and the fine stone concrete layer 24 are filled between the exterior wall and the floor slab 2, and then the weather-resistant sealant layer 25 and the external fiber cement board 26 are applied to seal the outside of the floor slab 2, and the inner side of the exterior wall panel 1 is coated with the internal fiber cement board 15. Finally, the insulation board layer 9 is installed on the outermost layer of the exterior wall panel 1 and the floor slab 2 to have the effect of thermal insulation and fire prevention.

[0056] The above description is only a preferred embodiment of the present invention. To keep the description concise, not all possible combinations of the various technical features in the above embodiment are described. This does not limit the present invention in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
