Description

Technical Field

[0001] This utility model relates to a wall tie, and more particularly to an improved wall tie for building construction, mainly used in scaffolding projects in building construction, replacing the traditional steel pipe fastener wall tie, and belongs to the technical field of building construction supplies. Background Technology

[0002] Generally, external scaffolding is a common yet difficult-to-manage measure in construction projects, and the overall stability of the scaffolding is crucially related to the wall ties. Wall ties are key components ensuring the overall rigidity of the scaffolding is not compromised; they bear tensile and compressive forces. Common wall ties are divided into rigid and flexible types. Rigid components use pre-embedded steel pipes for direct connection, while flexible components use a combination of steel bars or wires and steel pipes. Traditional construction methods are prone to causing quality problems later on, and residual issues are difficult to handle after the scaffolding is dismantled. During building construction, it is necessary to erect external protective scaffolding and connect it to the main building structure through wall ties to ensure the overall stability of the external protective scaffolding. There are various conventional methods for using wall ties.

[0003] Traditional wall ties are constructed using a pre-embedded steel pipe method. Before concrete pouring, a short vertical steel pipe is embedded approximately 20cm inside the beam, with about 20cm protruding from the back of the beam. After the concrete is poured, a horizontal steel pipe connects the upright to the short vertical pipe. This traditional method has several drawbacks: firstly, the location of the wall ties affects the construction of the building's exterior walls, requiring pre-drilled holes. These holes can only be sealed and repaired after the scaffolding is dismantled, posing a significant risk of leakage; secondly, installation and dismantling are complex and cumbersome, making it generally inconvenient.

[0004] Currently, a search reveals that Chinese utility model patent CN215717122U discloses a sleeve-connected external scaffold wall tie device, comprising a bent section (1), a straight section (2), a connecting sleeve (3), and a wall tie crossbar (4); the bent section (1) and the straight section (2) are provided with external threads at opposite ends, and after the bent section (1) and the straight section (2) are joined together, they are locked into a whole by the connecting sleeve (3); the other end of the straight section (2) is overlapped and fixed to the wall tie crossbar (4). Although the above patent can solve the problem of fixing the external scaffold wall, it still has the following technical drawbacks:

[0005] On the one hand, the pre-embedded end is just a 18mm diameter round steel with a bend, which has limited stability in the wall. On the other hand, the connection between the horizontal steel pipe and the scaffolding is simply made by using building fasteners or bolt assemblies. This method may pose a safety hazard due to the loosening of building fasteners or bolt assemblies during long-term use.

[0006] On the other hand, the connecting sleeve (3) is not equipped with a corresponding structure that makes it easy to tighten or loosen by hand or with tools, which makes it inconvenient during installation or disassembly.

[0007] Another aspect is that the straight section 2 of the wall tie and the horizontal bar 4 of the wall tie are fixed by welding, which is not convenient during disassembly.

[0008] The traditional wall ties mentioned above have many problems and shortcomings, such as potential floor leakage due to pre-embedding in the floor slab, inadequate subsequent repairs, or unstable installation and dismantling. Therefore, the key to solving these technical problems lies in developing an improved wall tie for building construction that is more practical and reliable. Summary of the Invention

[0009] To address the numerous defects and shortcomings of the aforementioned background technology, this utility model improves and innovates upon them, aiming to provide an improved wall tie for building construction. This improves operator safety, reduces operation time, and facilitates quick and easy installation and dismantling. Firstly, it eliminates the need for patching and thus avoids water seepage risks. Since the pre-embedded mechanism directly connects to the building to form an integrated structure, it does not require subsequent removal. Therefore, it increases the load-bearing capacity and stability of the wall tie itself, thereby enhancing the overall integrity and stability of the building and significantly reducing the possibility of loosening and instability of the pre-embedded mechanism due to external forces. This design reduces connection gaps between different components, resulting in more even stress distribution on the building and the pre-embedded mechanism when subjected to external forces, avoiding localized stress concentration and improving the structure's earthquake and wind resistance. Secondly, the pre-embedded design can be completed in one step during construction, eliminating the need for additional installation and reinforcement later, reducing the steps and complexity of the construction process. This effectively shortens the construction cycle, reduces construction costs, and simultaneously achieves a simple design structure, flexible installation, improved efficiency, reduced external wall seepage, reduced wall repairs, and guaranteed quality.

[0010] Another objective of this invention is that, due to the use of a sleeve connection, the installation and removal of wall ties are more flexible and convenient, the scope of application is expanded, and the requirements for hole position accuracy control are reduced during drilling or pre-embedding.

[0011] Another objective of this invention is to provide a physical locking effect through the setting of limiting components, ensuring a more secure connection between wall ties. This design effectively prevents relative displacement of the wall ties under stress or vibration, thereby enhancing the overall stability of the structure. It also provides a more intuitive docking method during construction, ensuring that operators are less likely to misalign or misfit the wall ties during installation. This not only improves construction efficiency but also reduces subsequent maintenance costs caused by improper installation.

[0031] The handheld part (22) is provided with a ring-shaped anti-slip sleeve that works in conjunction with it, wherein:

[0033] Preferably, the anti-slip sleeve is a rubber sleeve, on which several ring-shaped or granular protective protrusions or strip-shaped anti-slip patterns are provided.

[0034] Therefore, since a non-slip sleeve is provided on the hand-held part (22) to match it, it can ensure that the operator's hands are protected from wear and tear during long-term use.

[0035] Preferably, the connecting rod (3) is a lead screw or a threaded rod with an external thread section.

[0036] Preferably, the limiting member (4) is connected to the outer frame connecting rod (6) through at least one locking component (5), and the outer frame connecting rod (6) is connected to the scaffold (8) through the scaffold fastener (7).

[0038] The clamp (51) is a U-shaped or C-shaped structure; and the open end of the U-shaped or C-shaped structure is provided with an external thread section;

[0039] A fixing plate (52) is fitted onto the free end of the clamp (51);

[0041] Preferably, the clamp (51) passes through the limiting groove (42) of the limiting member (4) and the outer frame connecting rod (6), and the end is fastened by the anti-detachment member (53);

[0042] The working principle is as follows: Before using the above-mentioned improved wall tie for building construction, the operator only needs to transport this utility model to the designated construction location for installation using appropriate handling equipment or directly by hand.

[0043] Before installation, the operator only needs to pre-embed multiple pre-embedded mechanisms (1) in the building (9) according to the construction requirements. When pre-embedding, it is necessary to pre-embed at the designated position of the corresponding building (9) according to the construction standards. After the pre-embedding is completed, it needs to be cured. After curing to meet the requirements, it can be installed and used.

[0044] Before installation and use, the operator only needs to connect one end of the pre-prepared sleeve (2) to the mounting part (12) of the pre-embedded mechanism (1) by means of internal and external thread connection, and then connect the connecting rod (3) to the other end of the sleeve (2) by thread connection, and then install the installation limiting part (4) on the connecting rod (3). At the same time, adjust the limiting part (4) to the reasonable position of the connecting rod (3) and tighten it so that it is fastened to the connecting rod (3) as a whole. Thus, the installation of this utility model is completed, and it can then be used.

[0045] When in use, the operator only needs to use the pre-prepared locking component (5) to detachably connect the external frame connecting rod (6) and the limiting component (4) into a whole, and the end is fastened by the anti-detachment component (53). Then, the external frame connecting rod (6) and the scaffold (8) are detachably connected into a whole using building fasteners. After checking that it is stable and reliable, the subsequent corresponding building construction procedures can be carried out.

[0046] During construction, operators only need to stand at the corresponding construction position on the scaffold (8) to carry out construction. During the construction process, operators also need to regularly check whether the connection of each component is stable and reliable. If there is any looseness, it is necessary to tighten and fix it in time.

[0047] Finally, as time goes by, after the construction work is completed, the operator only needs to dismantle the various parts of this utility model. Specifically, when dismantling, the operator only needs to loosen the anti-detachment part (53), remove the fixing plate (52) from the clamp (51) to separate them from each other, and then remove the clamp (51) to separate one end of the external frame connecting rod (6) from the limiting part (4). Then loosen the building fastener to separate the other end of the external frame connecting rod (6) from the scaffold (8).

[0048] Then, the operator removes the limiting piece (4) from the connecting rod (3);

[0049] Next, loosen the sleeve (2). When loosening, the operator can manually or by using a wrench to rotate counterclockwise to separate one end of the connecting rod (3) from one end of the sleeve (2), thereby separating the other end of the sleeve (2) from the mounting part (12) of the pre-embedded mechanism (1) and completing the dismantling of this utility model.

[0050] Finally, after cleaning and repairing the dismantled parts, the operators will manually or using appropriate handling equipment move them to the designated tool storage location for storage, so that they can be reused in the future.

[0051] In summary, the beneficial effects of this utility model compared with the prior art are as follows:

[0052] 1. Because of the embedded part (1), this utility model not only enhances the bearing area and firmness of the embedded part (1), making the scaffold more stable and personnel safer, but also improves work efficiency and reduces wear and tear through the design of the locking component (5).

[0053] 2. Both ends of the sleeve (2) of this utility model are provided with connecting parts (21). The connecting parts (21) are sleeves with internal thread sections. The internal thread sections are rotated in the same or opposite directions. The outer surface of the sleeve is provided with protrusions (211) that facilitate the tightening or loosening of tools. A hand-held part (22) is formed between the two connecting parts (21). The hand-held part (22) is recessed for easy gripping.

[0054] 3. The handheld part (22) of this utility model is provided with a ring-shaped anti-slip sleeve that works in conjunction with it. The anti-slip sleeve is a rubber sleeve with several ring-shaped or granular protective protrusions or strip-shaped anti-slip patterns. Therefore, it can ensure that the operator's hands are protected from wear and tear during long-term use.

[0055] 3. The limiting component of this utility model includes a limiting sleeve body (41) and a limiting slot (42). The limiting sleeve body (41) is a hollow tubular body with an internally threaded section in the annular shape inside the tubular body, which facilitates fine adjustment of the distance between the outer frame and the embedded part and makes it more secure.

[0056] 4. The limiting slot (42) of this utility model is an annular slot. Several annular slots are provided. Several limiting slots (42) are arranged in annularly or unequally at intervals on the outer wall of the limiting sleeve body (41). It can withstand more force directions and is more solid and stable.

[0057] 5. The locking assembly (5) of this utility model consists of a clamp (51), a fixing plate (52), and an anti-disengagement component (53).

[0077] In order to make the technical means, creative features, achieved objectives and effects of the present utility model easy to understand, the technical solution of the present utility model will be further described in detail below in conjunction with the attached drawing documents and specific implementation manners. It should be noted that, without conflict, the embodiments and features in the embodiments in this application can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0078] Embodiment 1

[0079] As shown in the attached Figure 1 to the attached Figure 8 of the specification, an improved wall connecting member for building construction includes:

[0080] An embedding mechanism 1, one end of the embedding mechanism 1 is embedded in a building 9;

[0081] A sleeve 2, one end of the sleeve 2 is connected to the embedding mechanism 1, and the other end is connected to a connecting rod 3;

[0082] A connecting rod 3, on which a limiting member 4 is installed;

[0083] A limiting member 4, the limiting member 4 is sleeved on the connecting rod 3.

[0084] Furthermore, as shown in Figure 5 , the embedding mechanism 1 includes:

[0085] An embedded part 11, the fixed end of the embedded part 11 is provided with an installation part 12 extending therefrom;

[0086] The installation part 12 is connected to the middle of the fixed end of the embedded part 11;

[0087] Among them, the embedded part 11 is of a "mountain-shaped" or "U-shaped" or "E-shaped" structure;

[0088] The installation part 12 is a rod-shaped member, and an external thread section is annularly provided on the outer wall of the rod-shaped member.

[0089] Furthermore, as shown in Figure 5-8 , the embedded part 11 includes:

[0090] A vertical embedded rod 111, the vertical embedded rod 111 is vertically embedded in the building 9;

[0091]

[0092] A plurality of horizontal embedded rods 112 are symmetrically or asymmetrically connected to both sides of the vertical embedded rod 111.

[0092] In an improved construction wall tie structure as described above, the vertical embedded rod 111 and the horizontal embedded rod are first connected by welding, threaded tightening, or snap-fit ​​fixing. During the pouring process, one end of the embedded mechanism 1, which has a "mountain-shaped," "claw-shaped," or "E-shaped" structure, is pre-embedded into the building. The mounting part 12, located in the middle of the fixed end of the embedded part, protrudes from the outer wall of the building 9. The mounting part 12 is rod-shaped and has an external thread structure.

[0093] This design structure also has another usage state, such as Figure 8 As shown, when using it, first connect the vertical embedded rod 111 and the horizontal embedded rod. The connection method is welding, thread tightening or buckle fixing. The embedded mechanism is "King" shaped at this time. Before pouring, first connect one end of the bend pipe to the installation part 12 of the structure by tightening and loosening the thread. The other end of the bend pipe is connected to one end of the straight pipe by tightening and loosening the thread. The other end of the straight pipe has an external thread structure, which can be connected to the internal thread end of the sleeve 2.

[0094] The two usage scenarios described above allow the embedded mechanism to be directly connected to the building, forming an integrated structure that does not require subsequent removal. This increases the load-bearing capacity and stability of the wall ties themselves, while also enhancing the overall integrity and stability of the building, significantly reducing the possibility of the embedded mechanism loosening and becoming unstable due to external forces. This design reduces connection gaps between different components, resulting in a more even distribution of stress on the building and the embedded mechanism when subjected to external forces, avoiding localized stress concentration and improving the structure's earthquake and wind resistance.

[0095] Example 2

[0096] Furthermore, such as Figure 2-3 As shown, it also includes:

[0097] The limiting sleeve body 41 is a hollow tubular body with an internal thread section circumferentially arranged inside the tubular body.

[0098] The limiting slot 42 is arranged in a ring on the limiting sleeve body 41.

[0099] Furthermore, such as Figure 7 As shown, the limiting slot 42 is an annular slot, and several annular slots are provided. The several limiting slots 42 are arranged in annularly or unequally at intervals on the outer wall of the limiting sleeve body 41.

[0100] In this utility model, the limiting member 4 specifically includes: a limiting sleeve body 41 and a limiting groove 42. The limiting sleeve body 41 is a hollow tubular structure with an internally threaded section on its inner ring for through-sleeving connection with the connecting rod 3 whose outer surface is covered with external threads. The tight connection between the internal and external threads provides lateral rigidity, making the overall structure of the wall connection more stable. The limiting groove 42 is an annular groove provided on the outer surface of the limiting member 4. There are at least two grooves, spaced a certain distance apart, which may be fixed or not. The annular groove allows the clamp 51 to pass through, and then it is fixed together with the outer frame connecting rod 6 at the U-shaped bend of the clamp 51. Then, the limiting member 4 and the outer frame connecting rod 6 are connected and fastened together by the fixing plate 52 and the anti-detachment member 53. The annular groove on the limiting groove 42 not only allows for a tight connection with the clamp 51, but also provides a lateral rigid support after the fixing plate 52 and the anti-detachment component 53 are connected, making the connection between the wall tie and the scaffold more stable.

[0101] In this invention, the design of the limiting component effectively prevents relative displacement of the wall ties under stress or vibration, thereby enhancing the overall stability of the structure. It also provides a more intuitive connection method during construction, ensuring that operators are less likely to misalign or misfit the wall ties during installation. This not only improves construction efficiency but also reduces subsequent maintenance costs caused by improper installation.

[0102] Furthermore, such as Figure 6 As shown, both ends of the sleeve 2 are provided with connecting parts 21, and a hand-held part 22 is formed between the two connecting parts 21. The hand-held part 22 is recessed for easy gripping.

[0103] Furthermore, such as Figure 6-8 As shown, the connecting part 21 is a sleeve with an internal thread section, and the outer surface of the sleeve has a protrusion 211 for easy tightening or loosening with a tool.

[0104] Example 3

[0105] This embodiment 3 is the same as embodiment 1 and embodiment 2, except that the handheld part 22 is provided with an integrated or separate anti-slip structure, and the anti-slip structure is provided with several ring-shaped or granular protective protrusions or strip-shaped anti-slip patterns.

[0106] In this utility model, the handheld part 22 is provided with a ring-shaped anti-slip protective sleeve that works in conjunction with it to complete the function, wherein:

[0107] The internal threads inside the connecting part 21 can rotate in the same or opposite directions. The outer surface of the sleeve has protrusions 211 for easy tightening or loosening with tools. A handhold 22 is formed between the two connecting parts 21. The handhold 22 is recessed for easy gripping and is annularly equipped with a rubber sleeve that works in conjunction with it. The rubber sleeve has several ring-shaped or granular protective protrusions or strip-shaped anti-slip patterns. Therefore, it can protect the operator's hands from wear and tear during prolonged use.

[0108] When using an improved wall tie for building construction based on the above-mentioned design structure, firstly after the pouring is completed and the pre-embedded mechanism 1 is pre-embedded,

[0109] Furthermore, such as Figure 7 As shown, the connecting rod 3 is a lead screw or a threaded rod with an external thread section.

[0110] Furthermore, such as Figure 1 As shown, the limiting member 4 is connected to the external frame connecting rod 6 through at least one locking component 5, and the external frame connecting rod 6 is connected to the scaffold 8 through the scaffold fastener 7.

[0111] In the above-mentioned improved wall tie structure for building construction, after the pouring is completed and the pre-embedded mechanism 1 is pre-embedded, the external scaffold connecting rod 6 and the scaffold 8 are connected by scaffold fasteners 7. Then, the connecting rod 3 and the limiting member 4 are connected by tightening. The clamp 51 passes through the limiting groove 42 on the limiting member 4. Then, the limiting member and the external scaffold connecting rod 6 are locked and fixed by the fixing plate 52 and the anti-detachment member 53. Finally, one end of the sleeve 2 is tightened to the mounting part 12 of the pre-embedded mechanism 1, and the other end of the sleeve 2 is tightened to the connecting rod 3. The sleeve 2 has a recessed hand-held part 22 in the middle with an annular anti-slip protective sleeve on its outer surface. The anti-slip protective sleeve is a rubber sleeve with several ring-shaped or granular protective protrusions or strip-shaped anti-slip patterns. This increases the friction during installation and disassembly, allowing operators to hand-tighten at the beginning and end of tightening, thus shortening the installation and disassembly time. However, if it cannot be turned by hand, a wrench or other fastening tools can be used to tighten or loosen the protrusions 211 at both ends of the sleeve. This design can protect the operator's hands from wear and tear during long-term use.

[0112] Example 4

[0113] In this embodiment 4, as Figure 2-4 As shown, the locking assembly 5 includes:

[0114] Clamp 51, clamp 51 has a U-shaped or C-shaped structure; and the open end of the U-shaped or C-shaped structure is provided with an external thread section;

[0115] Fixing plate 52, which is fitted onto the free end of clamp 51;

[0116] Anti-detachment component 53, which is screwed to the end of the fixing plate 52, connects the limiting component 4 and the outer frame connecting rod 6 into a whole.

[0117] In this utility model, the clamp 51 passes through the limiting groove 42 of the limiting member 4 and the outer frame connecting rod 6, and its end is fastened by the anti-detachment member 53.

[0118] In an improved construction wall tie structure as described above, the extended end of the clamp 51 has threads or clips for fastening the anti-detachment component 53. Two holes are provided on the fixing plate 52, allowing the extended end of the clamp 51 to pass through and be fastened to the anti-detachment component 53. The straight section length of the clamp 51 ensures that after passing through the upper limit slot 42 of the limiting component 4 and the external scaffold connecting rod 6, there is still sufficient length for the fixing plate 52 and the anti-detachment component 53 to be installed and fastened, thus securing the connection between the limiting component 4 and the external scaffold connecting rod 6. Then, the connection between the clamp and the sleeve 2 and the embedded mechanism 1 is made.

[0119] Other installation and usage methods are the same as in Examples 1 to 3, and will not be repeated here.

[0120] In summary, a more specific embodiment of this utility model is as follows:

[0121] like Figure 2 As shown, an improved wall tie for building construction includes a pre-embedded mechanism 1, a sleeve 2, a connecting rod 3, a limiting component 4, a locking assembly 5, an external scaffolding connecting rod 6, a scaffolding coupler 7, a scaffold 8, and a building 9.

[0122] During installation, in the pouring process, the pre-embedded mechanism 1 is first embedded into the building 9, and scaffolding 8 is erected. The external scaffolding connecting rod 6 is connected to the scaffolding 8 through scaffolding fasteners 7. Then, the internal and external threads between the connecting rod 3 and the limiting member 4 are tightened by screwing. The clamp 51 is passed through the limiting slot 42 on the limiting member 4, the external scaffolding connecting rod 6, and the fixing plate 52 in sequence. The anti-loosening part 53 is used to tighten and fix the end of the clamp 51. Finally, the sleeve 2 and one end of the connecting member 12 of the pre-embedded mechanism 1 can be connected by hand first, and then the other end of the connecting member 12 is connected to the connecting rod 3. Alternatively, one end of the connecting part 21 can be tightened to the connecting member 12 first, and then the other end can be tightened to one end of the connecting rod 3. The limiting member 4 is screwed in and fixed from the other end of the connecting rod 3. After the limiting member 4 is rotated to the appropriate position on the connecting part 3, the limiting member 4 and the external scaffolding connecting rod 6 are connected and fixed by the clamp 51 in the same way as above, and will not be repeated here.

[0123] During dismantling, first loosen the anti-detachment component 53, remove the fixing plate 52 from the slot 51, and then pull the clamp 51 away from the upper limit slot 42 end of the limiting component 4, thus separating the limiting component 4 from the outer frame connecting rod 6. Next, loosen both ends of the sleeve 2 connecting part 21 using a wrench or other tools, or by hand. Then, loosen the sleeve 2 from the connecting rod 3, and then unscrew the limiting component 4 from the connecting rod 3. Finally, after cleaning and repairing the dismantled components, the operators manually or using appropriate handling equipment transport them to the designated tool storage location for storage, ready for future reuse.

[0124] In this utility model, the internal thread sections inside the connecting parts 21 at both ends of the sleeve 2 have the same or opposite rotation directions.

[0125] In this utility model, the connection is either a fixed connection or a detachable connection. The fixed connection is either a welded connection or a directly machined integral structure, while the detachable connection is either an internal or external threaded connection, a snap-fit ​​connection, or a plug-in structure connection.
