[0031] To make the objectives, technical solutions, and beneficial effects of this application clearer, the preferred embodiments of this application will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding by those skilled in the art.
[0032] Example 1:
[0033] See Figure 1 and Figure 2 A connection structure between masonry and wall columns, comprising masonry 1 and wall column body 2, wherein the connection structure between masonry and wall columns further includes:
[0034] Connecting sleeve 3 is cast into the masonry 1;
[0035] Tie bar 4 is embedded in the mortar between the blocks of the wall column body 2;
[0036] The connecting sleeve 3 and the tie bar 4 are respectively provided with internal threads and external threads at one axial end, and the internal and external threads are matched to make the connecting sleeve 3 and the tie bar 4 threadedly connected.
[0037] Specifically, the construction begins with the pre-embedding of connecting sleeves 3 during the reinforcement binding stage of the wall and column concrete structure. The anchoring position of the tie bars 4 during the construction of the wall and column main body 2 is determined based on the elevation. Connecting sleeves 3 are reserved at 500mm intervals along the height direction of the masonry 1 and are securely fixed to the structural reinforcement. During the concrete pouring process, the opening of the connecting sleeves 3 needs to be sealed to prevent debris from entering. During the subsequent masonry construction of the wall and column main body 2, the bottom layer of masonry blocks is laid first. When the masonry reaches the pre-embedded connecting sleeves 3, a tie bar 4 with one end processed with a straight thread is rotated and anchored into the mortar between the masonry blocks of the wall and column main body 2, and the bricklaying continues upwards.
[0038] In this application, the connecting sleeve 3 is pre-embedded and cast into the masonry 1. After the tie bar 4 is threadedly connected to the connecting sleeve 3, it is then embedded in the mortar between the masonry blocks of the wall column body 2. In this way, the connection method of drilling holes and planting reinforcement bars on the wall column and reverse tie bar is avoided, thereby avoiding damage to the main structure of the wall column and avoiding irreversible damage, thus avoiding potential quality problems.
[0039] Example 2:
[0040] Based on Embodiment 1, optionally, the connecting sleeve 3 is a straight thread sleeve.
[0041] Specifically, straight thread connections offer high strength. In straight thread connections, the contact surface between the thread teeth is large and uniform, enabling them to withstand greater tensile and compressive forces. In steel reinforcement connections within the construction industry, straight thread sleeve connections allow the strength at the joint of the tie bar 4 to approach or even exceed the strength of the tie bar 4 itself, ensuring structural stability and safety. Straight thread processing is simple, and the tooth profile and dimensions can be precisely controlled, resulting in more accurate fit between the connectors and reducing connection loosening issues caused by thread errors. Thus, the straight thread connection between the tie bar 4 and the connecting sleeve 3 ensures the connection strength between the masonry 1 and the wall / column main body 2, enhancing the stability of the connection.
[0042] Optionally, the connecting sleeve 3 has the following specifications: 100mm in length, 8mm in inner diameter, 5mm in wall thickness, and the tie bar 4 has a diameter of 8mm.
[0043] Specifically, the inner diameter of the connecting sleeve 3 is the same as the diameter of the tie bar 4 to facilitate their connection and fitting; the connecting sleeve 3 is 100mm long, which ensures that its non-threaded section has sufficient length to be embedded in the masonry 1, while the threaded section also has sufficient length to be threadedly connected to the tie bar 4. The larger threaded contact area can improve the connection strength; the wall thickness of the connecting sleeve 3 is 5mm to ensure that the sleeve has sufficient strength to withstand the tension or pressure when the tie bar 4 is connected, and to avoid deformation or breakage.
[0044] Example 3:
[0045] See Figure 3 Based on the above embodiments, optionally, the end of the connecting sleeve 3 away from the internal thread is provided with a semi-circular hook 5.
[0046] Specifically, the semi-circular hook 5 increases the mechanical interlocking effect between the connecting sleeve 3 and the concrete, thereby improving the anchoring performance of the connecting sleeve 3 in the concrete and preventing the connecting sleeve 3 from being pulled out of the concrete when under stress, thus improving the connection stability and reliability of the masonry 1 and the wall column body 2.
[0047] Optionally, two semicircular hooks 5 are provided symmetrically.
[0048] Specifically, the two semi-circular hooks 5 are symmetrical about the axis of the connecting sleeve 3. This symmetrical arrangement can counteract torque, achieve mechanical balance, prevent the connecting sleeve 3 from rotating, and adapt to combined loads. The symmetrical arrangement can also double the mechanical interlocking area, thereby increasing the anchoring force. In this way, the connection stability and reliability of the masonry 1 and the wall column body 2 are further improved.
[0049] Example 4:
[0050] See Figure 4 Based on the above embodiments, optionally, the connecting sleeve 3 is provided with a plurality of barbs 6 along its circumference.
[0051] Specifically, the barbs 6 form a one-way locking structure, strengthening the mechanical interlocking. When the connecting sleeve 3 is under tension, the barbs 6 embed into the surrounding concrete, generating a mechanical locking effect similar to a "fishhook," preventing the connecting sleeve 3 from being pulled out along the axial direction. The barbs 6 increase the contact area between the connecting sleeve 3 and the concrete medium, significantly increasing the frictional force under the same axial tensile force, thereby enhancing the anchoring force. In this way, by preventing the connecting sleeve 3 from coming out through the barbs 6, the connection stability and reliability of the masonry 1 and the wall column body 2 are improved.
[0052] Optionally, the barbs 6 are made of spring steel.
[0053] Specifically, during installation, the barbs 6 are elastically compressed by the concrete. After the concrete hardens, the barbs 6 rebound and embed into the concrete pores, forming a composite anchoring system of "barbs-concrete mechanical interlocking + elastic pre-tightening force". In this way, the connection stability and reliability of the masonry 1 and the wall column 2 are further improved.
[0054] In addition, spring steel has a short springback response time, which can form an effective anchor without waiting for material creep; the deformation compatibility of spring steel allows the barbs 6 to maintain geometric integrity under complex stress, such as maintaining an anchoring efficiency of more than 85% under temperature changes.
[0055] It should be noted that the structures and / or installation methods not detailed in this application are those that can be known by those skilled in the art in combination with common knowledge and / or prior art, and are not the focus of this application, and will not be elaborated further here.
[0056] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this application; the dimensions of the drawings are not related to the specific physical object, and the physical object dimensions can be arbitrarily changed.
