Description

Technical Field

[0001] This utility model relates to the field of installation structure technology, and in particular to a modular prefabricated parapet wall installation structure. Background Technology

[0002] The installation structure is used in modular buildings to install prefabricated parapet walls onto the building roof. The installation structure consists of positioning holes, grouting chambers, and grouting holes at the bottom of the prefabricated parapet wall. During installation, steel shims are placed on the reinforcing bars on the building roof. Then, the prefabricated parapet wall is lifted by a crane and placed onto the reinforcing bars on the roof of the modular building, so that the reinforcing bars are inserted into the positioning holes. Then, diagonal supports and 7-shaped supports are installed to support the prefabricated parapet wall. Then, dry-hardened cement mortar is used to fill the gap between the building roof and the prefabricated parapet wall. The lower grouting holes are plugged. Then, a grouting machine is inserted into the upper grouting hole to grout. After the grouting chamber is full, it flows out through the other upper grouting holes and grouting is stopped. Then, the upper grouting holes are plugged and wait for solidification to complete the installation of the prefabricated parapet wall.

[0003] The inventors discovered in their daily work that during the installation of the structure, the precast parapet wall was difficult to align with the positioning holes on the roof due to the swaying motion of the crane. It usually required the cooperation of multiple workers to hold the precast parapet wall and place it onto the steel bars. At the same time, another worker needed to hold a mirror to check whether the positioning holes at the bottom of the precast parapet wall and the steel bars were aligned, which could make the installation process quite cumbersome. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in actual use, due to the swaying of the precast parapet wall lifted by the crane, it is difficult to directly align the steel bars on the building roof with the positioning holes of the precast parapet wall and insert them. Usually, multiple workers are required to work together to hold the precast parapet wall and place it on the steel bars. At the same time, another worker needs to hold a mirror to check whether the positioning holes at the bottom of the precast parapet wall and the steel bars are aligned, which may make the installation process cumbersome. Therefore, a modular precast parapet wall installation structure is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a modular prefabricated parapet wall installation structure, including a positioning hole opened at the bottom of the prefabricated parapet wall, a grouting cavity opened inside the prefabricated parapet wall, a grouting hole opened on the front of the prefabricated parapet wall communicating with the grouting cavity, a pre-fixing component and a building roof provided at the bottom of the prefabricated parapet wall, the pre-fixing component including an L-shaped sliding rod slidably inserted at both ends of the bottom of the prefabricated parapet wall, a first limiting plate provided at the left end of the L-shaped sliding rod, and a second limiting plate provided on the front of the L-shaped sliding rod.

[0006] The effect achieved by the above components is as follows: by setting up pre-fixing components, when the precast parapet wall needs to be installed on the building roof by the crane, the area enclosed by the L-shaped sliding rods on both sides, the first limiting plate and the second limiting plate are respectively inserted into the steel bars on the left and right sides of the building roof, thereby limiting the precast parapet wall and aligning the positioning hole with the steel bar. Then the precast parapet wall is lowered so that the steel bar is inserted into the positioning hole, thereby facilitating the installation of the precast parapet wall onto the building roof steel bars as much as possible.

[0007] Preferably, a mounting hole is provided on one side of the first limiting plate and the second limiting plate, and a threaded rod is provided on the inner wall of the mounting hole via a bearing for rotatable connection. A circular rod is fixedly connected to one side of the first limiting plate and the second limiting plate, and an L-shaped slide rod is slidably inserted into the circular rod. The threaded rod is threadedly connected to the L-shaped slide rod.

[0008] The effect achieved by the above components is as follows: when the reinforcing bar is in the area enclosed by the L-shaped sliding rod, the first limiting plate, and the second limiting plate, the threaded rod in the mounting hole is rotated by the rotating mechanism, which, together with the round rod, causes the first limiting plate and the second limiting plate to come into contact with the L-shaped sliding rod, thereby limiting the distance between the parapet wall and the reinforcing bar with the help of the L-shaped plate.

[0009] Preferably, the first limiting plate and the second limiting plate are slidably inserted into the prefabricated parapet wall, and the front of the threaded rod is provided with a hexagonal groove for external hand drill.

[0010] The effect achieved by the above components is: when a hand drill is inserted into the hexagonal slot and the hand drill is started, the threaded rod in the mounting hole rotates.

[0011] Preferably, one side of the precast parapet wall and the building roof is provided with an installation component that is fixedly connected by bolts. One side of the installation component is rotatably connected to a lead screw, and a threaded sleeve is threadedly connected between the two lead screws. The threads on both sides of the inner wall of the threaded sleeve are opposite.

[0012] The effect achieved by the above components is as follows: the two mounting parts are installed to the precast parapet wall and the building roof respectively by bolts, and then the threaded sleeve is rotated to bring the two threaded rods closer together, thereby supporting the precast parapet wall.

[0013] Preferably, a pre-limiting component is provided between the mounting component and the precast parapet wall. The pre-limiting component includes a limiting circular block fixedly connected to the back of the mounting component. A positioning block is slidably inserted into the arc surface of the limiting circular block, and the positioning block is inserted into the precast parapet wall.

[0014] The effect achieved by the above components is as follows: when the mounting component is positioned against the precast parapet wall, the mounting component is manually dragged, and at the same time, the pulling mechanism is used to completely retract the positioning block to the limiting circular block, so that the reset mechanism is compressed. After the limiting circular block is completely locked into the precast parapet wall, the pulling mechanism is loosened, the reset mechanism is reset, so that the positioning block is locked into the precast parapet wall, thereby pre-positioning the mounting component against the precast parapet wall, and then fixing it with bolts.

[0015] Preferably, a pull rope is fixedly connected to the lower end of the positioning block, and the pull rope passes through the limiting circular block and the mounting component.

[0016] The effect achieved by the above components is that pulling the pull rope causes the positioning block to retract completely into the limiting circular block.

[0017] Preferably, a spring is fixedly connected to the lower end of the positioning block, and the other end of the spring is fixed to the limiting circular block.

[0018] The effect achieved by the above components is that pulling the pull rope causes the positioning block to retract completely to the limiting circular block, thereby compressing the spring.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] In this invention, by setting a pre-fixing component, when the precast parapet wall lifted by the crane needs to be installed onto the steel reinforcement on the building roof, the area enclosed by the L-shaped sliding rods on both sides, the first limiting plate, and the second limiting plate is respectively inserted into the steel reinforcement on the left and right sides of the building roof, thereby limiting the precast parapet wall and aligning the positioning hole with the steel reinforcement. Then, the precast parapet wall is lowered so that the steel reinforcement is inserted into the positioning hole, thus facilitating the installation of the precast parapet wall onto the steel reinforcement on the building roof. This solves the problem that when the precast parapet wall is lifted by the crane and sways, it is difficult to directly align the steel reinforcement on the building roof with the positioning hole of the precast parapet wall. Usually, multiple workers are required to work together to hold the precast parapet wall and place it onto the steel reinforcement, and another worker needs to hold a mirror to check whether the positioning hole at the bottom of the precast parapet wall is aligned with the steel reinforcement, which may make the installation process cumbersome.

[0027] Reference Figure 1 As shown, this utility model provides a technical solution: a modular prefabricated parapet wall installation structure includes a positioning hole opened at the bottom of the prefabricated parapet wall 1, a grouting cavity opened inside the prefabricated parapet wall 1, a grouting hole 4 opened on the front of the prefabricated parapet wall 1 communicating with the grouting cavity, and a pre-fixing component 2 and a building roof 5 provided at the bottom of the prefabricated parapet wall 1.

[0028] Reference Figure 2 and Figure 3As shown in this embodiment: the pre-fixing component 2 includes L-shaped sliding rods 21 that are slidably inserted at both ends of the bottom of the precast parapet wall 1. A first limiting plate 22 is provided at the left end of the L-shaped sliding rod 21, and a second limiting plate 23 is provided at the front end of the L-shaped sliding rod 21. By setting the pre-fixing component 2, when the precast parapet wall 1, which needs to be lifted by the crane, is installed onto the steel bars on the building roof 5, the area enclosed by the L-shaped sliding rods 21 on both sides, the first limiting plate 22, and the second limiting plate 23 is respectively inserted into the steel bars on the left and right sides of the building roof 5, thereby fixing the parapet wall 1. The precast parapet wall 1 is positioned to align the positioning hole with the reinforcing bar. Then, the precast parapet wall 1 is lowered so that the reinforcing bar is inserted into the positioning hole, thus facilitating the installation of the precast parapet wall 1 onto the reinforcing bar of the building roof 5. One side of the first limiting plate 22 and the second limiting plate 23 has an installation hole 24. The inner wall of the installation hole 24 is provided with a threaded rod 25 that is rotatably connected by a bearing. A circular rod 26 is fixedly connected to one side of the first limiting plate 22 and the second limiting plate 23. An L-shaped sliding rod 21 is slidably inserted into the circular rod 26. The threaded rod 25 is threadedly connected to the L-shaped sliding rod 21. When the reinforcing bar is in the area enclosed by the L-shaped sliding rod 21, the first limiting plate 22, and the second limiting plate 23, the threaded rod 25 in the mounting hole 24 is rotated by the rotating mechanism. This, in conjunction with the circular rod 26, causes the first limiting plate 22 and the second limiting plate 23 to come into contact with the L-shaped sliding rod 21. This, in turn, helps the L-shaped plate to limit the distance between the parapet wall 1 and the reinforcing bar. The first limiting plate 22 and the second limiting plate 23 are slidably inserted into the precast parapet wall 1. The front of the threaded rod 25 has a hexagonal opening for connecting a hand drill. Insert a hand drill into the hexagonal slot 27 and start the drill to rotate the threaded rod 25 in the mounting hole 24. One side of the precast parapet wall 1 and the building roof 5 is provided with a mounting piece 6 that is fixedly connected by bolts. One side of the mounting piece 6 is rotatably connected to a threaded rod 8. A threaded sleeve 7 is threaded between the two threaded rods 8. The threads on both sides of the inner wall of the threaded sleeve 7 are opposite. Install the two mounting pieces 6 to the precast parapet wall 1 and the building roof 5 respectively by bolts. Then rotate the threaded sleeve 7 to bring the two threaded rods 8 closer together, thereby supporting the precast parapet wall 1.

[0029] Reference Figure 4 and Figure 5As shown in this embodiment: a pre-limiting component 3 is provided between the mounting component 6 and the precast parapet wall 1. The pre-limiting component 3 includes a limiting circular block 31 fixedly connected to the back of the mounting component 6. A positioning block 32 is slidably inserted into the arc surface of the limiting circular block 31. The positioning block 32 is inserted into the precast parapet wall 1. When the mounting component 6 is limited to the precast parapet wall 1, the mounting component 6 is manually dragged, and at the same time, the pulling mechanism is used to make the positioning block 32 completely retract into the limiting circular block 31, so that the reset mechanism is compressed. After the limiting circular block 31 is completely locked into the precast parapet wall 1, the pulling mechanism is loosened. The reset mechanism resets, causing the positioning block 32 to engage with the precast parapet wall 1, thereby pre-limiting the mounting piece 6 to the precast parapet wall 1. Then, it is fixed with bolts. The lower end of the positioning block 32 is fixedly connected to a pull rope 34, which passes through the limiting circular block 31 and the mounting piece 6. Pulling the pull rope 34 causes the positioning block 32 to fully retract to the limiting circular block 31. The lower end of the positioning block 32 is fixedly connected to a spring 33, and the other end of the spring 33 is fixed to the limiting circular block 31. Pulling the pull rope 34 causes the positioning block 32 to fully retract to the limiting circular block 31, thus compressing the spring 33.

[0030] Working principle:

[0031] During the installation of the precast parapet wall 1, steel shims are placed on the reinforcing bars on the roof 5 of the building. Then, the precast parapet wall 1 is lifted by a crane and placed onto the reinforcing bars on the roof 5 of the modular building, ensuring the reinforcing bars are engaged in the positioning holes. Next, diagonal supports and 7-shaped brackets are installed to support the precast parapet wall 1. Then, dry-hardened cement mortar is used to seal the gap between the roof 5 and the precast parapet wall 1. The lower grouting hole 4 is plugged. Then, a grouting machine is inserted into the upper grouting hole 4 to inject grout. After the grouting cavity is full, the upper... After grouting flows out of the other grouting holes 4 on the side, stop grouting. Then, plug the upper grouting hole 4 with a plug and wait for solidification to complete the installation of the precast parapet wall 1. When the precast parapet wall 1, which needs to be lifted by the crane, needs to be installed onto the steel bars on the building roof 5, the area enclosed by the L-shaped sliding rods 21 on both sides, the first limiting plate 22, and the second limiting plate 23 are respectively inserted into the steel bars on the left and right sides of the building roof 5, thereby limiting the precast parapet wall 1 and aligning the positioning hole with the steel bar. Then, the precast parapet wall 1 is lowered so that the steel bar is inserted into the positioning hole, thereby maximizing the installation of the precast parapet wall 1. This facilitates the installation of the precast parapet wall 1 onto the reinforcing bars of the building roof 5. When the reinforcing bars are within the area enclosed by the L-shaped sliding rod 21, the first limiting plate 22, and the second limiting plate 23, a hand drill is inserted into the hexagonal groove 27 and started. This causes the threaded rod 25 in the mounting hole 24 to rotate, cooperating with the round rod 26, so that the first limiting plate 22 and the second limiting plate 23 come into contact with the L-shaped sliding rod 21. This, in conjunction with the L-shaped plate, limits the distance between the parapet wall 1 and the reinforcing bars. The two mounting components 6 are then bolted to the precast parapet wall 1 and the building roof 5, respectively. Then, rotate the threaded sleeve 7 to bring the two threaded rods 8 closer together, thereby supporting the precast parapet wall 1. When the mounting part 6 is limited to the precast parapet wall 1, manually drag the mounting part 6 and at the same time pull the pull rope 34 to make the positioning block 32 fully retract to the limiting circular block 31, so that the spring 33 is compressed. After the limiting circular block 31 is fully inserted into the precast parapet wall 1, loosen the pull rope 34, the spring 33 returns to its original position, so that the positioning block 32 is inserted into the precast parapet wall 1, thereby pre-limiting the mounting part 6 to the precast parapet wall 1, and then fixing it with bolts.
