Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lightweight wall materials, specifically a connection structure between a hollow ribbed partition wall and a main wall. Background Technology
[0002] In the prior art, the connection between the hollow ribbed partition wall and the main wall is achieved by installing the connector to the main wall with expansion bolts, and then installing the hollow ribbed partition wall onto the connector.
[0003] like Figure 3 As shown, in actual construction, the minimum distance A between the support parts of the two connecting pieces needs to remain unchanged, and the horizontal position of the support parts of the two connecting pieces needs to be fixed to ensure that the horizontal position of the cavity ribbed partition wall is fixed. Since the positions of the connecting pieces and the expansion bolts are fixed, the position of the expansion bolts on the main wall is also fixed. Therefore, in actual construction, it is easy for the expansion bolts to hit the vertically extending main reinforcement of the main wall, causing damage to the main reinforcement of the main wall. Utility Model Content
[0004] Purpose of the utility model: To provide a connection structure between a hollow ribbed partition wall and the main wall, which can adjust the position of the fasteners while fixing the position of the connecting piece, thereby reducing the probability of the fasteners hitting the main reinforcement of the main wall.
[0005] The technical solution of this utility model is: a connection structure between a hollow ribbed partition wall and a main wall, which is disposed between the hollow ribbed partition wall and the main wall, and the connection structure includes: fasteners and connecting pieces.
[0006] The connecting piece includes a main body and a supporting part. The supporting part extends from the main body in a direction away from the main wall and is used to cooperate with the cavity ribbed partition wall.
[0007] The main body is provided with an elongated hole that extends horizontally.
[0008] At least two of the fasteners are connected to the main wall through the elongated hole, so that the connecting piece is fixed between the head of the fastener and the main wall.
[0009] In a further embodiment, the connection structure further includes an extension.
[0010] The extension member is installed on the support part and extends from the main body in a direction away from the wall, such that the dimension from the end of the extension member to the main body is greater than the length of the mortar wall of the cavity ribbed partition wall × 1 / 5.
[0011] In a further embodiment, the dimension from the end of the extension member to the main body is ≥700mm, which can ensure the connection strength between the connection structure and the cavity ribbed partition wall, thereby ensuring the effective connection between the cavity ribbed partition wall and the main wall.
[0012] In a further embodiment, the extension and the support are welded together to ensure the connection strength between the extension and the support.
[0013] In a further embodiment, the minimum distance from the elongated hole to the support portion is ≥30mm.
[0014] In a further embodiment, the fastener is an expanded-base bolt, which further improves the strength of the connecting piece when installed on the main wall compared to the expansion bolts of the prior art.
[0015] In a further embodiment, the connecting piece includes a main body and two support parts.
[0016] The elongated hole is located between the two supporting parts, and the keel of the hollow ribbed partition wall is located between the two supporting parts.
[0017] In a further embodiment, the width of the inner template of the cavity ribbed partition wall is ≤ the minimum distance between the two supports ≤ the width of the mortar wall of the cavity ribbed partition wall.
[0018] In a further embodiment, the connection structure includes at least three sets of fasteners and connecting pieces.
[0019] Multiple connecting pieces are distributed along the height of the mortar wall of the cavity ribbed partition wall, enabling multi-point connection between the main wall and the cavity ribbed partition wall, further ensuring the effective connection between the cavity ribbed partition wall and the main wall.
[0020] The beneficial effects of this utility model are as follows: by having the fastener pass through the elongated hole on the connecting piece, which extends horizontally, the fastener can be moved horizontally during construction to avoid the main reinforcement of the main wall before being connected to the main wall. During this process, the horizontal position of the connecting piece remains unchanged, greatly reducing the probability of the fastener hitting the main reinforcement of the main wall. This solves the problem in the prior art where fasteners can easily damage the main reinforcement of the main wall when trying to ensure the horizontal position of the connecting piece and the hollow ribbed partition wall.

Detailed Implementation
[0025] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0026] This utility model discloses a connection structure between a cavity ribbed partition wall and a main wall, which can adjust the position of the fastener while fixing the position of the connecting piece, thereby reducing the probability of the fastener hitting the main reinforcement of the main wall.
[0027] like Figure 1 The connecting structure shown is set between the hollow ribbed partition wall 1 and the main wall 2. The hollow ribbed partition wall 1 includes an inner formwork 11 and a mortar wall 12. The inner formwork 11 is set inside the mortar wall 12. The main wall 2 includes concrete and main reinforcement bars. The main reinforcement bars extend vertically and are set in the concrete.
[0028] like Figure 2 The connection structure shown includes: fastener 4 and connecting piece 3. The connecting piece 3 includes: main body 31 and support part 32. The support part 32 extends from the main body 31 in a direction away from the main wall 2. The support part 32 is used to cooperate with the cavity ribbed partition wall 1.
[0029] The main body 31 is provided with an elongated hole 311, which extends horizontally.
[0030] At least two fasteners 4 pass through the elongated hole 311 and are connected to the main wall 2, so that the connecting piece 3 is fixed between the head of the fastener 4 and the main wall 2.
[0031] like Figure 2 The connection structure shown also includes an extension member 5, which is installed on the support portion 32 to form a new extended support portion 32. At this time, the size of the support portion 32 is calculated as a whole consisting of the extension member 5 and the support portion 32. The extension member 5 extends from the main body portion 31 in a direction away from the wall, such that the dimension B from the end of the extension member to the main body portion is greater than the length dimension of the mortar wall 12 of the cavity ribbed partition wall 1 × 1 / 5. In the preferred embodiment, the dimension B from the end of the extension member to the main body portion is ≥ 700 mm.
[0032] The extension member 5 and the support part 32 can be connected by screwing, riveting, welding or other methods. In the preferred embodiment, the extension member 5 and the support part 32 are welded together.
[0033] In this embodiment, the minimum distance A from the elongated hole to the support is ≥30mm. A sufficiently long spacing facilitates the installation of the fastener 4. The length of the elongated hole 311 is ≥ the maximum head diameter of five fasteners 4. For example, the head diameter of a φ8 expanded bolt is 14mm, so the length of the elongated hole 311 needs to be ≥70mm. When the minimum distance A between the two supports is 500mm and the minimum distance C from the elongated hole 311 to the support is 30mm, the length of the elongated hole 311 is 440mm. The length of the elongated hole 311 can be between 70 and 440mm. In the preferred embodiment, the length of the elongated hole 311 is the maximum value of 440mm.
[0034] The fastener 4 can be an expansion bolt or a flared bolt. In a preferred embodiment, the fastener 4 is a flared bolt.
[0035] like Figure 2 The connecting piece 3 shown includes a main body 31 and two support parts 32.
[0036] The elongated hole 311 is located between the two support parts 32, and the keel of the hollow ribbed partition wall 1 is located between the two support parts 32.
[0037] The width of the inner formwork 11 of the hollow ribbed partition wall 1 is less than or equal to the minimum distance A between the two supports and the width of the mortar wall 12 of the hollow ribbed partition wall 1.
[0038] like Figure 1 The connection structure shown includes at least three sets of fasteners 4 and connecting pieces 3.
[0039] Multiple connecting pieces 3 are distributed along the height direction of the mortar wall 12 of the cavity ribbed partition wall 1.
[0040] During construction, a 50×4mm flat iron can be made with an elongated hole 311 in the middle and its two ends can be bent to form a support part 32 as a connecting piece 3.
[0041] Using a φ8 expanded-bottom bolt as fastener 4, the width of the elongated hole 311 is between 8.2 and 10 mm in order to be compatible with the standard φ8 expanded-bottom bolt, so that the main body 31 can be fixed between the head of the fastener 4 and the main wall 2.
[0042] Then, according to the construction requirements, mark at least three fixing positions of connecting pieces 3 and the position of long holes 311 on the main wall 2. Select the fixing position of fastener 4 in the long hole 311. When the fixing positions of fastener 4 at both ends of the long hole 311 interfere with the main reinforcement of the main wall 2, select the fixing position of fastener 4 in the middle of the long hole 311.
[0043] Then, the φ6 steel bar is used as an extension 5 and welded to the support 32 for fixation.
[0044] Then, the three connecting pieces 3 are installed on the main wall 2 using fasteners 4, so that the fasteners 4 are installed away from the main reinforcement bars, while the position of the connecting pieces 3 remains unchanged.
[0045] Finally, when installing the hollow ribbed partition wall 1, the extension piece 5 and the support part 32 are placed on the outside of the inner template of the hollow ribbed partition wall 1. Then, the outer side of the inner template 11 is wrapped with galvanized welded wire mesh and premixed finished mortar to form a mortar wall 12. The distance between the two sets of extension pieces 5 and support parts 32 is set so that the extension pieces 5 and support parts 32 do not connect with the inner template 11 of the hollow ribbed partition wall 1.
[0046] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
