Description

Technical Field

[0001] This utility model relates to the field of climbing formwork technology, and more specifically to a climbing formwork suspension pre-embedded device. Background Technology

[0002] Climbing formwork (climbing formwork) is a self-climbing formwork system consisting of formwork, climbing frame, and climbing equipment. It is mainly used for the construction of high-rise buildings, cylindrical structures, and bridge piers. The climbing frame and climbing equipment are suspended from the wall by climbing cone components pre-embedded in the wall. The climbing cone component mainly consists of four parts: embedded plate, screw rod, climbing cone, and positioning bolt. The embedded plate is fixedly installed on the screw rod, and the climbing cone is installed on the screw rod by threads. The formwork has pre-drilled installation holes. During pre-embedding, the climbing cone is fitted against the inside of the formwork and aligned with the installation holes. Then, the positioning bolt is screwed into the climbing cone from the outside of the formwork to fix the entire climbing cone component. During the formwork closing process, the climbing cone component enters the tied steel cage. Currently, most existing climbing cone components have a circular embedded plate, which may collide with the rebar cage during the process of entering the rebar cage. However, during the formwork closing process, it is difficult for workers to adjust the rebar cage or screws inside the formwork. If the formwork is forcibly closed, it may cause the screws and climbing cones to deviate, affecting subsequent use. Therefore, it is urgent to design a climbing formwork suspension embedded device to solve the above problems. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a climbing formwork suspension pre-embedded device to solve the problems existing in the background art.

[0004] This utility model provides the following technical solution: a climbing formwork suspension pre-embedded device, including a main screw, a climbing cone, and a positioning bolt, and also includes a pre-embedded component and a locking component. The pre-embedded component is fixedly installed on the main screw, the climbing cone is slidably installed on the main screw through a thread, the positioning bolt is slidably installed inside the climbing cone through a thread, the locking component is disposed inside the main screw, and the locking component is threadedly connected to the main screw. The pre-embedded component includes a fixed sleeve, several mounting seats, and several rotating pre-embedded plates. The fixed sleeve is fixedly installed on the main screw, the several mounting seats are circumferentially fixedly installed on the fixed sleeve at equal intervals, the rotating pre-embedded plates are elastically rotatably installed on the mounting seats, and the positioning bolt has a through hole.

[0005] Furthermore, the pre-embedded component also includes several fixing rods, which are fixedly installed in the mounting base, and the pre-embedded plate is rotatably sleeved on the fixing rods.

[0006] Furthermore, the pre-embedded component also includes several torsion springs, which are sleeved on the fixed rod, and the two ends of the torsion springs are respectively connected to the mounting base and the rotating pre-embedded plate.

[0007] Furthermore, the pre-embedded component also includes several baffles, which are fixedly installed on one side of the rotating pre-embedded plate.

[0008] Furthermore, the locking assembly includes a secondary screw, a circular plate, and several insert rods. The secondary screw is slidably installed inside the main screw via a thread, the circular plate is rotatably installed at one end of the secondary screw, and several insert rods are circumferentially fixedly installed on the side of the circular plate near the fixing sleeve. The baffle plate has slots that cooperate with the insert rods.

[0009] Furthermore, the locking assembly also includes two limiting rods, both of which are fixedly installed at one end of the main screw, and the circular plate is slidably sleeved between the outer circumferential walls of the two limiting rods.

[0010] Furthermore, the locking assembly also includes a baffle plate, which is fixedly installed between one end of the two limiting rods, and the circular plate is located between the baffle plate and the main screw.

[0011] Furthermore, a cross-shaped groove is provided at the other end of the auxiliary screw.

[0012] The technical effects and advantages of this utility model are as follows: I. In the process of mold closing, if the rotating embedded plate collides with the steel cage, the rotating embedded plate is elastically rotated on the mounting base by the torsion spring. Therefore, the rotating embedded plate will generate elastic rotation under the obstruction of the steel reinforcement, avoiding rigid contact with the steel cage. This will prevent the main screw and climbing cone from being misaligned, thus improving the stability of the main screw and climbing cone during the mold closing process. II. In this utility model, after all the pre-embedded components have entered the steel cage, the rotating pre-embedded plate will also detach from the steel reinforcement. At this time, the rotating pre-embedded plate will be reset to a vertical state under the action of the torsion spring. After the mold is closed, a screwdriver is inserted through the through hole and the auxiliary screw is rotated through the cross-shaped groove to drive the circular plate and several insert rods to approach the baffle, so that the insert rods are inserted into the slots on the baffle and the circular plate is in contact with the baffle, thus locking the baffle and the rotating pre-embedded plate and preventing them from being pressed by the concrete during concrete pouring.

[0015] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0016] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0017] A climbing formwork suspension pre-embedded device includes a main screw 1, a climbing cone 3, and a positioning bolt 4. It also includes a pre-embedded component 2 and a locking component 5. The pre-embedded component 2 is fixedly installed on the main screw 1. One end of the climbing cone 3 is sleeved on the outside of the main screw 1 and threadedly connected to it. The other end is threadedly connected to the positioning bolt 4. The outer diameter of the climbing cone 3 gradually increases in the direction away from the main screw 1. The locking component 5 is disposed inside the main screw 1 and is threadedly connected to the main screw 1. The pre-embedded component 2 includes a fixed sleeve 201, several mounting seats 202, and several rotating pre-embedded plates 204. The fixed sleeve 201 is fixedly installed on the end of the main screw 1 away from the climbing cone 3. Several mounting seats 202 are circumferentially fixedly installed on the fixed sleeve 201. One end of the rotating pre-embedded plate 204 is rotatably installed on the corresponding mounting seat 202.

[0018] Specifically, the pre-embedded component 2 also includes several fixing rods 203, which are fixedly installed inside the mounting base 202, and the pre-embedded plate 204 is rotatably sleeved on the outside of the fixing rods 203.

[0019] Specifically, the pre-embedded component 2 also includes several torsion springs 205, which are sleeved on the fixed rod 203. The two ends of the torsion springs 205 are connected to the mounting base 202 and the rotating pre-embedded plate 204.

[0020] Specifically, the pre-embedded component 2 also includes several baffles 206, which are fixedly installed on one side of the rotating pre-embedded plate 204.

[0021] Specifically, the locking assembly 5 includes a secondary screw 501, a circular plate 502, and several insert rods 503. The secondary screw 501 is disposed inside the main screw 1 and threadedly connected to it. The circular plate 502 is rotatably mounted on the end of the secondary screw 501 away from the climbing cone 3. Several insert rods 503 are circumferentially fixedly mounted on the side of the circular plate 502 near the fixing sleeve 201. The baffle 206 has slots 207 that cooperate with the insert rods 503.

[0022] Specifically, the locking assembly 5 also includes two limiting rods 504, which are symmetrically fixedly installed on the end face of the main screw 1 away from the climbing cone 3, and the circular plate 502 is slidably sleeved between the two limiting rods 504.

[0023] In this embodiment, the circular plate 502 can be limited by the limiting rod 504. When the auxiliary screw 501 slides and drives the circular plate 502 to slide, the circular plate 502 is kept sliding in parallel.

[0024] Specifically, the locking assembly 5 also includes a baffle 505, which is fixedly installed between the free ends of the two limit rods 504, and the circular plate 502 is located between the baffle 505 and the main screw 1.

[0025] In this embodiment, the baffle 505 can block the circular plate 502 to prevent it from detaching from the two limit rods 504.

[0026] Specifically, the other end of the auxiliary screw 501 is provided with a cross-shaped groove 506.

[0027] In this embodiment, through the provided cross-shaped groove 506, workers can use a screwdriver to rotate the auxiliary screw 501 by passing through the through hole 6.

[0028] Working principle: During use, the main screw 1, embedded component 2, climbing cone 3, and locking component 5 are fixedly installed on the template using positioning bolts 4. Then, the template is closed. During the closing process, if the rotating embedded plate 204 collides with the reinforcing cage, since the rotating embedded plate 204 is rotatably sleeved on the fixed rod 203, the rotating embedded plate 204 will rotate towards the fixed sleeve 201 under the obstruction of the reinforcing steel. During the rotation, the torsion spring 205 is compressed. Therefore, the embedded component 2 will not make rigid contact with the reinforcing cage. When the embedded component 2 is fully inserted into the reinforcing cage, the rotating embedded plate 204 will also detach from the reinforcing steel, at which point the torsion spring 205 will be released. The rotating embedded plate 204 is pushed back to the vertical position. After the mold is closed, a screwdriver is inserted through the through hole 6 and the auxiliary screw 501 is rotated through the cross-shaped groove 506, causing the auxiliary screw 501 to slide outward. Since the auxiliary screw 501 is rotatably connected to the circular plate 502, when the auxiliary screw 501 slides outward, it will drive the circular plate 502 and several insert rods 503 to approach the baffle 206. The auxiliary screw 501 is continuously rotated so that the insert rods 503 are inserted into the slots 207 on the baffle 206, and the circular plate 502 is made to fit against the baffle 206, thus locking the baffle 206 and the rotating embedded plate 204 to prevent them from being pressed by the concrete during concrete pouring.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
