Description

Technical Field

[0001] This invention relates to the technical field of wall tie installation in building construction, and in particular to a novel wall tie based on an isolated nano-plastic external formwork and its installation method. Background Technology

[0002] Isolated nano-plastic external formwork allows for the one-time molding of external wall insulation and the main external wall structure, significantly saving construction time. However, when isolated nano-plastic external formwork is used for the main external wall, the following disadvantages exist due to the fact that the thickness of isolated nano-plastic external formwork is generally around 10cm and the material of nano-plastic external formwork is relatively soft: The thickness of isolated nano-plastic external formwork is greater than 10cm. Considering the size of the external formwork keel and the pre-embedded depth of the bolts, the length of the pre-embedded bolts is insufficient, requiring at least 30cm, which is often insufficient. Furthermore, because the bolts extend far beyond the structural wall, they cannot meet the rigidity requirements of the wall ties under pressure. Secondly, the connection between the bolts and steel pipes is usually welded. Although isolated nano-plastic external formwork is a non-combustible material with a fire resistance rating of A, welding on its outer side can cause the nano-plastic board to melt, affecting the insulation performance.

[0003] When pre-installing ordinary wall ties, the wall ties are usually installed first, followed by the template. Precise measurements are required before installation, and holes need to be drilled in the template. The construction is relatively troublesome and the construction accuracy is difficult to guarantee. Summary of the Invention

[0004] To address the issue of wall tie installation accuracy and reduce damage to the isolated nano-plastic external formwork during installation, this invention provides a novel wall tie based on the isolated nano-plastic external formwork and its installation method.

[0005] On the one hand, the novel wall tie based on an isolated nano-plastic external formwork provided by the present invention adopts the following technical solution: A novel wall tie based on an isolated nano-plastic external formwork includes a wall tie pipe, short steel bars, and right-angle fasteners. One end of the wall tie pipe is equipped with a short steel bar, which intersects with the wall tie pipe to form a cross shape. One end of the wall tie pipe with the short steel bar is pre-embedded in the building wall, and the other end of the wall tie pipe is fixedly connected to the required external fasteners through the right-angle fasteners. The wall-connecting pipe passes through the fixing through hole on the isolated nano-plastic outer template, and the gap between the fixing through hole and the wall-connecting pipe is sealed with sealant.

[0006] By adopting the above technical solution, the wall-connecting pipe and short steel bars form a cross structure, which increases the tensile strength with the wall and improves the stability of the installation of the external fasteners. Right-angle fasteners are used to connect the external fasteners. The wall-connecting pipe passes through the fixing through holes on the isolated nano-plastic outer formwork, reducing damage to the isolated nano-plastic outer formwork. The sealant effectively ensures the integrity of the isolated nano-plastic outer formwork, thereby improving the thermal insulation effect of the isolated nano-plastic outer formwork.

[0007] Preferably, the wall-connecting pipe and the short steel bar are rotatably connected to each other at the contact connection point, and the short steel bars are distributed on both sides of the contact connection point with one side longer than the other.

[0008] By adopting the above technical solution, the wall ties and short steel bars are connected by mutual cross rotation at the contact connection point, which allows the wall ties and short steel bars to be inserted into the isolated nano-plastic outer formwork without obstruction. At the same time, the distribution of one side being longer and the other side being shorter enables the wall ties and short steel bars to form a cross structure again after insertion.

[0009] Preferably, connecting components are fixed on both sides of the wall-connecting pipe, and multiple wall-connecting pipes are connected end to end through the connecting components.

[0010] By adopting the above technical solution, the connecting component can extend the wall-connecting pipe, which is beneficial for connecting the wall-connecting pipe to more and farther external fasteners.

[0011] Preferably, the wall-connecting pipe is provided with scale lines, which mark the length of the wall-connecting pipe extending into the isolated nano-plastic outer template, and also include installation direction markings.

[0012] By adopting the above technical solution, the scale line helps to install the wall tie pipe, prevents the wall tie pipe from being installed too deep or too shallow, and the directional mark helps to indicate the installation angle, ensuring that the short steel bar can be extended.

[0013] Preferably, a branch pipe mounting component is movably provided on the wall-connecting pipe, the branch pipe mounting component is sleeved on the wall-connecting pipe, and the branch pipe mounting component includes an inclined branch pipe mounting port and a vertical pipe mounting port.

[0014] By adopting the above technical solution, the branch pipe installation component can realize the expansion connection of the wall connection pipe and improve the installation stability of the wall connection pipe.

[0015] Preferably, the wall-connecting pipe is equipped with a short inclined branch pipe and a long straight connecting pipe through a branch pipe installation component. The wall-connecting pipe is connected and supported on the wall-isolated nano-plastic outer template or the required external fastener through the short inclined branch pipe. Adjacent wall-connecting pipes are connected to each other through the long straight connecting pipe.

[0016] By adopting the above technical solutions, short inclined branch pipes are used to improve the inclined bracing and support the wall-connecting pipes to maintain a horizontal orientation, while long straight connecting pipes can connect the wall-connecting pipes into a whole, improving wind and earthquake resistance.

[0017] Preferably, the wall-connecting pipe is fixedly connected to the steel reinforcement of the building's exterior wall by wire rope.

[0018] By adopting the above technical solution, the wire rope helps to improve the installation stability of the wall-connecting pipe and reduce the deviation of the wall-connecting pipe during pouring.

[0019] On the other hand, the novel wall tie installation method based on isolated nano-plastic external formwork provided by the present invention adopts the following technical solution: The installation process includes the following steps: Precast wall ties are manufactured using factory customization, with the wall ties and short steel bars assembled in advance in the factory. The short steel bars are made from leftover waste and scrap materials from the construction site. Install the isolated nano-plastic external formwork and determine the installation position of the wall tie. Install the isolated nano-plastic external formwork on the outside of the outer wall after the steel bars are tied. Mark the installation position of the wall tie on the isolated nano-plastic external formwork and drill holes using a drill gun. To install the wall tie, pass the wall tie through the pre-drilled hole on the isolated nano-plastic outer template, measure and keep the wall tie perpendicular to the wall surface, and then fix the wall tie. Install aluminum alloy inner formwork and pour the wall. Install aluminum alloy inner formwork on the inside of the outer wall after the steel bars are tied. Then pour the wall and pour the wall tie inside the concrete. Wait for the concrete to solidify. Wait for the concrete to set and check the tensile strength of the wall ties; Connect and secure the required external fasteners to the wall ties.

[0020] By adopting the above technical solution, the short steel bars can effectively utilize the waste and scrap materials left over from the construction site, reducing construction costs. Installing the isolated nano-plastic outer formwork first and then determining the installation position of the wall tie components helps to improve the installation accuracy of the wall tie components and facilitates the processing of the isolated nano-plastic outer formwork. Checking the tensile strength of the wall tie components helps to ensure the stability of the wall tie components and reduce the risk of falling off.

[0021] Preferably, when installing the wall tie, the short steel bar is rotated to be collinear with the wall tie pipe, and the short steel bar is rotated to be inserted into the pre-drilled hole on the isolated nano-plastic outer template along with the wall tie pipe. The short steel bar is rotated vertically by gravity and remains perpendicular to the wall tie pipe.

[0022] By adopting the above technical solution, post-installation can be achieved while minimizing damage to the isolated nano-plastic outer formwork, maintaining its integrity and thermal insulation performance.

[0023] Preferably, when the external fasteners are connected to the wall ties, the branch pipe installation component is first installed on the wall tie pipe, then the connecting assembly is installed, and finally the branch pipe installation component and the connecting assembly are connected to other wall ties or connecting structures respectively.

[0024] By adopting the above technical solutions, the integrity of the wall ties is improved and the stress is kept uniform.

[0025] In summary, the present invention has the following beneficial technical effects: 1. The wall ties and short steel bars form a cross structure, increasing the tensile strength with the wall and improving the stability of the external fasteners. Right-angle fasteners are used to connect the external fasteners. The wall ties pass through the fixing holes on the isolated nano-plastic outer formwork, reducing damage to the isolated nano-plastic outer formwork. The sealant effectively ensures the integrity of the isolated nano-plastic outer formwork, thereby improving the thermal insulation effect of the isolated nano-plastic outer formwork.

[0026] 2. The interlocking and rotating connection between the wall tie pipe and the short reinforcing bar at the contact point allows for unobstructed insertion of both into the isolated nano-plastic outer formwork. The distribution of one side being longer than the other ensures that the wall tie pipe and short reinforcing bar form a cross structure again after insertion. The connecting components extend the wall tie pipe, facilitating the connection of more and more distant external fasteners. Scale lines aid in the installation of the wall tie pipe, preventing it from being installed too deep or too shallow, while directional markings indicate the installation angle, ensuring the short reinforcing bar can extend fully.

[0027] 3. Branch pipe installation components enable the expansion and connection of wall ties, improving their installation stability. Short inclined branch pipes are used to raise the diagonal braces and support the wall ties to maintain a horizontal orientation, while long straight branch pipes can connect the wall ties into a whole, improving wind and earthquake resistance. Wire ropes help improve the installation stability of the wall ties and reduce their displacement during pouring.

[0028] 4. Short reinforcing bars are effectively utilized from leftover waste and scraps on the construction site, reducing construction costs. Installing the isolated nano-plastic external formwork first, followed by determining the wall tie installation positions, improves the installation accuracy of the wall ties and facilitates the handling of the isolated nano-plastic external formwork. Checking the tensile strength of the wall ties helps ensure their stability and reduces the risk of detachment. During subsequent installation, damage to the isolated nano-plastic external formwork is minimized, maintaining its integrity and insulation performance. This improves the overall integrity of the wall ties and ensures uniform stress distribution.

[0029] 5. Simple structure and easy operation, facilitating understanding and implementation by on-site personnel. The wall ties are connected to the scaffold using steel pipe couplers, ensuring that the bidirectional stress of the wall ties meets requirements and guarantees the stability of the scaffold. Widely applicable, suitable for various formwork systems such as wooden formwork, aluminum alloy formwork, and isolated N-plastic insulated external formwork. The location of the wall ties can be flexibly selected, suitable for various external scaffolding systems such as steel pipe coupler scaffolding and disc-lock scaffolding. Factory-customized and batch-processed, saving construction time; simultaneously eliminating on-site welding, reducing on-site fire safety hazards while ensuring the thermal insulation performance of the isolated N-plastic insulated external formwork.

[0036] During processing, two grooves are cut into the top and bottom of the wall-connecting pipe 1, and a hole is made at the junction of the two grooves. The short steel bar 2 is placed at the junction of the two grooves and hinged through the hole at the junction. The short steel bar 2 is 55% of its length on one side and 45% of its length on the other side at the hinge point.

[0037] The wall-connecting pipe 1 is fixed with connecting components 11 on both sides, and multiple wall-connecting pipes 1 are connected end to end by connecting components 11.

[0038] The connecting component 11 is divided into a nut connector and a bolt connector, which are welded to both sides of the wall-connecting pipe 1 respectively.

[0039] After the nut connector and bolt connector are connected and tightened, they are locked in place using a pin.

[0040] The wall-connecting pipe 1 is provided with scale lines, which mark the length of the wall-connecting pipe 1 extending into the isolated nano-plastic outer template, and also include installation direction markings.

[0041] The installation direction is marked with a triangle or a dot, and the correct position is when the installation direction mark is pointing directly upwards.

[0042] A branch pipe mounting component 12 is movably installed on the wall-connecting pipe 1. The branch pipe mounting component 12 is fitted onto the wall-connecting pipe 1. The branch pipe mounting component 12 includes an inclined branch pipe mounting port 121 and a vertical pipe mounting port 122.

[0043] The inclined branch pipe installation port 121 forms a 45° angle with the wall-connecting pipe 1.

[0044] Both the inclined branch pipe installation port 121 and the vertical pipe installation port 122 are threaded.

[0045] The wall-connecting pipe 1 is equipped with a short inclined branch pipe 13 and a long straight pipe 14 through the branch pipe installation component 12. The wall-connecting pipe 1 is connected and supported on the wall isolation type nano-plastic outer template or the required external fastener through the short inclined branch pipe 13. Adjacent wall-connecting pipes 1 are connected to each other through the long straight pipe 14.

[0047] Alternatively, the wall-connecting pipe 1 can be welded to the external wall steel cage.

Install the isolated nano-plastic external formwork on the outside of the outer wall after the steel bars are tied.
