Description

Technical Field

[0001] This utility model relates to the field of steel structure building technology, and more specifically, it relates to a connector for steel structure buildings. Background Technology

[0002] During the construction and installation phase of steel structure buildings, the displacement of insulation materials seriously affects project quality and construction efficiency. Due to the dynamic adjustment characteristics of steel structure installation, pre-installed insulation materials often shift position, leading to numerous difficulties in subsequent construction.

[0003] Specifically, the displacement of insulation materials mainly causes the following problems: First, it creates gaps and voids in the insulation layer, forming thermal bridges and severely affecting the overall thermal insulation performance of the building. Second, the displaced insulation material needs to be repositioned and reinstalled, which not only increases labor costs but also delays the construction period. Third, some displaced insulation material may hinder the installation of other components and even affect structural safety.

[0004] Therefore, a connector for steel structure buildings is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a connector for steel structure buildings that reduces internal stress, avoids local thermal bridging, and improves the overall thermal insulation capacity.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A connector for steel structure buildings includes a first wall, a second wall disposed on one side of the first wall, a filling layer disposed between the first wall and the second wall, multiple sets of first steel frames disposed inside the first wall, multiple sets of second steel frames disposed inside the second wall, the first steel frames and the second steel frames being arranged parallel to each other, a transverse connecting assembly connecting the first steel frames and the second steel frames, and multiple sets of intermediate connectors disposed above the transverse connecting assembly; wherein, the transverse connecting assembly has at least one steel frame lug, a set of steel frame connecting holes is respectively opened at both ends of the steel frame lug, an abutment piece is disposed on one side of the steel frame lug, and multiple sets of release grooves are opened on the top of the abutment piece.

[0007] The present invention is further configured such that: the distance between the first steel frame and the second steel frame is the same as the length of the abutment piece, the length of the steel frame hanging lug is greater than the length of the abutment piece, and the release groove is an elliptical structure.

[0008] By adopting the above technical solution, the elliptical release groove can alleviate the deformation of the abutment piece when it is under force. On the other hand, the release groove can also reduce the internal stress of the transverse connecting component after manufacturing.

[0009] The present invention is further configured such that: the intermediate connecting member has a first right-angled piece, a second right-angled piece is provided on one side of the first right-angled piece, the first right-angled piece and the second right-angled piece are arranged intersectingly, and the first right-angled piece and the second right-angled piece have the same length.

[0010] The present invention is further configured such that: the first right-angle piece is provided with at least one first right-angle hook along the width direction, and the second right-angle piece is provided with at least one second right-angle hook along the width direction.

[0011] The present invention is further configured such that: a set of first connecting holes are respectively opened on both ends of the first right-angle hook, a set of second connecting holes are respectively opened on both ends of the second right-angle hook, two sets of first interlayer limiting holes are opened on the surface of the first right-angle hook, two sets of second interlayer limiting holes are opened on the surface of the second right-angle hook, and pins are inserted into the first interlayer limiting holes and the second interlayer limiting holes.

[0012] By adopting the above technical solution, during the construction process, multiple first walls, second walls, horizontal connecting components, and intermediate connecting parts need to be erected. By inserting pins into the first and second interlayer limiting holes on the same axis, the filling layer placed between the first and second steel frames is restricted to the left and right, preventing it from shifting and facilitating subsequent concrete pouring. Furthermore, by restricting the position of the filling layer, after the steel structure wall is completed, the distance between one side of the filling layer and the outer surface of the wall on that side is basically the same, thereby ensuring that the overall thermal insulation capacity of the wall is basically consistent, resulting in uniform thermal resistance. This avoids local thermal bridging, improves the overall thermal insulation capacity, and reduces the problem of condensation accumulation caused by uneven heating and cooling, preventing the internal structure from becoming damp or moldy.

[0013] The present invention is further configured such that the distance between the two sets of intermediate connecting members is greater than the height of the intermediate connecting members.

[0014] By adopting the above technical solution, the first right-angled piece, the second right-angled piece, and the first or second steel frame form a triangular structure, which can effectively limit the deformation of the first and second steel frames under stress in the middle.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. During the construction process, pins are inserted into the first and second interlayer limiting holes to limit the filling layer, facilitating subsequent concrete pouring. By limiting the position of the filling layer, after construction, the distance between one side of the filling layer and the outer surface of the wall on that side is basically the same, thus ensuring that the overall thermal insulation capacity of the wall is basically consistent. This results in uniform thermal resistance, avoiding local thermal bridging and improving the overall insulation capacity. On the other hand, it can reduce the problem of condensation accumulation caused by uneven heating and cooling, preventing the internal structure from becoming damp or moldy.

[0016] 2. The elliptical release groove can alleviate the deformation of the abutment piece when it is under stress. On the other hand, the release groove can also reduce the internal stress of the transverse connecting components after manufacturing. Attached Figure Description

Detailed Implementation

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0021] Example 1, please refer to Figure 1-7 The present invention provides the following technical solution: Specifically, it refers to a connector used in steel structure buildings, see [reference]. Figure 1-3 The structure includes a first wall 1, with a second wall 2 on one side of the first wall 1. Both the first wall 1 and the second wall 2 are side walls of a steel structure building. A filling layer 3 is provided between the first wall 1 and the second wall 2. The filling layer 3 is a filler with functions such as heat insulation, sound absorption, and heat insulation, such as rock wool, polystyrene foam, or one or more other materials. Multiple sets of first steel frames 11 are provided inside the first wall 1, and multiple sets of second steel frames 21 are provided inside the second wall 2. Both the first steel frames 11 and the second steel frames 21 are steel structure frames, arranged parallel to each other. A transverse connecting component 4 connects the first steel frames 11 and the second steel frames 21. Multiple sets of intermediate connecting parts 5 are provided above the transverse connecting component 4. The transverse connecting component 4 and the intermediate connecting parts 5 are used to connect the first steel frames 11 and the second steel frames 21, so that the first steel frames 11 and the second steel frames 21 are connected. The 21 sections are more tightly connected to reduce deformation. The transverse connecting component 4 and the intermediate connecting piece 5 can reduce the problem of bulging to both sides after the concrete is filled between the first wall 1 and the second wall 2, thereby avoiding building deformation. The vertical direction of the first steel frame 11 or the second steel frame 21 is the height direction, the opposite direction of the first steel frame 11 and the second steel frame 21 is the length direction, and the parallel direction of the first steel frame 11 and the second steel frame 21 is the width direction. A set of mesh is set on the side of the first steel frame 11 away from the filling layer 3 and the side of the second steel frame 21 away from the filling layer 3. The two sets of mesh can slow down the internal solidification speed of the concrete and avoid the problem of uneven wall strength caused by the concrete solidifying too quickly. On the other hand, the two sets of mesh can prevent the concrete from overflowing the area of ​​the first steel frame 11 and the second steel frame 21 when pouring concrete inward, thus improving the cleanliness of the construction site.

[0022] See Figure 4 The transverse connecting component 4 has two sets of steel frame lugs 41. Each end of the steel frame lug 41 has a set of steel frame connecting holes 42. An abutment piece 43 is provided on one side of the steel frame lug 41, and multiple release grooves 44 are provided on the top of the abutment piece 43. The distance between the first steel frame 11 and the second steel frame 21 is the same as the length of the abutment piece 43. The length of the steel frame lug 41 is greater than the length of the abutment piece 43, and the release grooves 44 are elliptical in shape.

[0023] Specifically, two sets of steel frame lugs 41 are connected to the first steel frame 11 and the second steel frame 21 by bolts. The abutment piece 43 abuts against the first steel frame 11 and the second steel frame 21 on both sides. The bottom ends of the first steel frame 11 and the second steel frame 21 are connected by this structure, which can avoid the problem of deformation of the first steel frame 11 or the second steel frame 21 when the steel frame is erected at a high place due to increased bottom force. The elliptical release groove 44 can alleviate the deformation of the abutment piece 43 when it is under force. On the other hand, the release groove 44 can also reduce the internal stress after the transverse connection component 4 is manufactured.

[0024] See Figure 5 The intermediate connector 5 has a first right-angled piece 51, and a second right-angled piece 52 is provided on one side of the first right-angled piece 51. The first right-angled piece 51 and the second right-angled piece 52 are arranged intersectingly, and the lengths of the first right-angled piece 51 and the second right-angled piece 52 are the same. The first right-angled piece 51 has a set of first right-angled lugs 53 along its width direction, and the second right-angled piece 52 has a set of second right-angled lugs 54 along its width direction. The first right-angled lugs 53 have a set of first connecting holes 55 on both ends, and the second right-angled lugs 54 have a set of second connecting holes 56 on both ends. The surface of the first right-angled lugs 53 has two sets of first interlayer limiting holes 57, and the surface of the second right-angled lugs 54 has two sets of second interlayer limiting holes 58. Pins are inserted into the first interlayer limiting holes 57 and the second interlayer limiting holes 58. The distance between the two sets of intermediate connectors 5 is greater than the height of the intermediate connector 5. The side away from the connection between the first right-angle piece 51 and the second right-angle piece 52 is the opening direction, and the opening direction of the intermediate connector 5 can be towards the first wall 1 or towards the second wall 2.

[0025] Specifically, the triangular structure formed by the first right-angle piece 51, the second right-angle piece 52, and the first steel frame 11 or the second steel frame 21 effectively limits the deformation of the first steel frame 11 and the second steel frame 21 under stress in the middle. Only one set of the first right-angle lug 53 and the second right-angle lug 54 is provided, suitable for use when the stress or deformation mainly occurs in the length direction, reducing the production cost of the intermediate connector 5. The intermediate connector 5 is fixed to the first steel frame 11 and the second steel frame 21 by bolts passing through the first connecting hole 55 and the second connecting hole 56, improving the structural strength of the middle part of the first steel frame 11 and the second steel frame 21. During the construction process, multiple of these first wall 1 and second wall 2 need to be erected. The transverse connecting component 4 and the intermediate connecting component 5, by inserting pins into the first interlayer limiting hole 57 and the second interlayer limiting hole 58 on the same axis, restrict the filling layer 3 placed between the first steel frame 11 and the second steel frame 21 to the left and right, preventing it from shifting and facilitating subsequent concrete pouring. Furthermore, by restricting the position of the filling layer 3, after the steel structure wall is constructed, the distance between one side of the filling layer 3 and the outer surface of the wall on that side is basically the same, thereby making the overall heat insulation capacity of the wall basically consistent, and thus obtaining uniform thermal resistance. This can avoid local thermal bridges and improve the overall heat insulation capacity. On the other hand, it can reduce the problem of condensation accumulation caused by uneven heating and cooling, and prevent the internal structure from becoming damp or moldy.

[0026] Example 2, see Figure 6 Compared with Embodiment 1, it has two sets of first right-angle hanging ears 53 and two sets of second right-angle hanging ears 54, which are suitable for situations where there is stress or deformation in both the length and width directions, and further improve the structural strength of the middle part of the first steel frame 11 and the second steel frame 21.

[0027] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
