Technical Field

[0001] The utility model relates to the technical field of box girder precast formwork, in particular to a rapid installation structure for box girder precast formwork. Background Technique

[0002] According to a precast box girder formwork disclosed in Chinese Patent No. CN 216372683 U, it includes: a bottom formwork, a left reinforcement frame and a right reinforcement frame are respectively fixedly installed at the bottom on the left and right sides of the bottom formwork, a left side formwork is installed on the top of the left side of the bottom formwork, a right side formwork is installed on the top of the right side of the bottom formwork, and an inner formwork is arranged in the cavity enclosed by the bottom formwork, the left side formwork and the right side formwork. In the utility model, through the left hydraulic push rod in the left reinforcement frame and the right hydraulic push rod in the right reinforcement frame, the left side formwork and the right side formwork can be respectively reinforced and supported, and the left hydraulic push rod and the right hydraulic push rod are convenient for moving the positions of the left side formwork and the right side formwork, and can play an auxiliary role during installation and mold opening, reducing the working intensity of the staff. By installing vibrators in the middle of the upper, lower, left and right four sides of the inner wall of the inner formwork, vibration can be carried out during concrete pouring, so that the concrete is evenly distributed into the formwork module, and it is suitable for wide promotion and use.

[0003] The existing precast box girder formwork can vibrate during concrete pouring to make the concrete evenly distributed into the formwork module, but there will be the following problems in the actual use process: 1. Traditional formwork installation often requires a large amount of manual operation, and the installation process is cumbersome and time-consuming; 2. The traditional formwork connection method may have insecure connections and be prone to loosening, so a rapid installation structure for box girder precast formwork is needed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a rapid installation structure for box girder precast formwork is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a rapid installation structure for box girder precast formwork, including a formwork, a limiting port is opened on the front surface of the formwork, an inlay ring is clamped on the front surface in the limiting port, an inclined groove is opened at the bottom in the inlay ring, the inclined groove inclines towards the limiting port, and a sliding groove is opened at the bottom in the limiting port.

[0006] Preferably, a clamp is installed inside the limiting port, and a glass storage is clamped inside the clamp.

[0007] Preferably, the glass storage stores concrete glue, the shape of the glass storage is spherical, and a fragile opening is provided in the middle of the front surface of the glass storage.

[0008] Preferably, a slider is bolted to the bottom of the fixture, and the slider is slidably connected to the chute.

[0009] Preferably, an installation joint is embedded in the back of the template. A buffer sleeve is threadedly connected to the front of the installation joint. A buffer damping rod is connected to the front of the buffer sleeve. A connecting head is threadedly connected to the front of the buffer damping rod.

[0010] Preferably, a push plate is threadedly connected to the front of the connecting head. A connecting column is threadedly connected to the front of the push plate. A binding head is threadedly connected to the front of the connecting column.

[0011] Preferably, the position of the limit opening on the front of the template is aligned with the position of the installation joint on the back.

[0012] Beneficial effects

[0013] In the present utility model, the template is designed in a modular manner and is combined with a quick-breaking structure to achieve rapid connection and fixation between the templates. This installation method greatly shortens the construction time and improves work efficiency. When the binding head breaks the glass reservoir, the internal concrete glue flows out and quickly solidifies, not only fixing the breaking structure in the limit opening but also achieving self-sealing between the templates, avoiding the leakage of concrete, and ensuring the construction quality. The designed buffer sleeve and buffer damping rod provide a slight shock-absorbing effect at the template connection, helping to reduce the impact of vibrations during construction on the template structure, increasing the stability and service life of the template.

[0014] In the present utility model, the template and its connection components are all modularly designed and can be flexibly combined and adjusted according to actual construction needs to adapt to the prefabrication requirements of box girders of different sizes and shapes. The design of the glass reservoir enables the rapid release and solidification of the concrete glue when needed, reducing the risk of human operation during construction and improving construction safety.

[0022] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0023] The specific embodiments of the present utility model will be described below in conjunction with the drawings. Specific embodiment 1:

[0025] Referring to Figures 1-5 , a rapid installation structure for a precast template of a box girder, including a template 1. A limit opening 3 is provided on the front surface of the template 1. An inserted ring 2 is clamped on the front surface inside the limit opening 3. An inclined groove 4 is provided at the bottom inside the inserted ring 2, and the inclined groove 4 inclines towards the inside of the limit opening 3. A slide groove 16 is provided at the bottom inside the limit opening 3.

[0026] The template 1 in this device is modular. Figure 1 As shown in the figure, it is a section of the template 1. During assembly, the components on the back of one section of the template 1 are inserted into the limit opening 3 of another section of the template 1.

[0027] A fixture 12 is installed inside the limit opening 3. A glass reservoir 13 is clamped inside the fixture 12. The glass reservoir 13 stores concrete glue inside. The shape of the glass reservoir 13 is spherical. A fragile opening 14 is provided in the middle of the front surface of the glass reservoir 13.

[0028] The fragile opening 14 part in the middle of the glass reservoir 13 is the most likely to break. With a single thrust from the tie head 11, it will be pierced and broken, and then the other parts will also crack accordingly.

[0029] The bottom of the fixture 12 is bolted with a slide block 15. The slide block 15 is slidably connected to the slide groove 16. The fixture 12 will clamp the glass reservoir 13. The concrete glue inside the glass reservoir 13 needs to ensure sufficient quantity to ensure that the entire inside of the limit opening 3 can be covered.

[0030] On the back of the template 1, an installation joint 5 is embedded. On the front of the installation joint 5, a buffer sleeve 6 is threadedly connected. On the front of the buffer sleeve 6, a buffer damping rod 7 is connected. On the front of the buffer damping rod 7, a connector 8 is threadedly connected. On the front of the connector 8, a push plate 9 is threadedly connected. On the front of the push plate 9, a connecting column 10 is threadedly connected. On the front of the connecting column 10, a tie head 11 is threadedly connected.

[0031] The installation joint 5, the buffer sleeve 6, the buffer damping rod 7, the connector 8, the push plate 9, the connecting column 10 and the tie head 11 together form a breaking structure. Here, the tie head 11 is similar to the breaking hammer hanging on the glass of high-speed trains.

[0032] The components installed on the installation joint 5 on the back of the template 1 are all assembled on-site, and the assembly method is also very simple, basically relying on threaded connections.

[0033] The limiting port 3 on the front of the template 1 and the installation joint 5 on the back are aligned with each other. The depth inside the limiting port 3 is the same as the length of the connecting column 10 plus the tie head 11. At the same time, the diameter of the push plate 9 is larger than the diameter of the limiting port 3. That is to say, the components on the back of the push plate 9 cannot enter the limiting port 3. In this way, a gap can be ensured between adjacent templates 1, which is more practical. Specific Embodiment 2:

[0035] Refer to Figures 1-5 , during actual use, lift two adjacent templates 1, and then insert the breaking structure on the back of one side template 1 into the corresponding limiting port 3 on the front of the other side template 1. The tie head 11 will first enter and push the glass reservoir 13 from the fragile opening 14 into the inside of the limiting port 3. When the back of the glass reservoir 13 hits the inner wall of the limiting port 3, the glass reservoir 13 will exert a reverse force on the tie head 11. In this way, the tie head 11 will first break the middle of the glass reservoir 13. After continuous extrusion, the entire glass reservoir 13 will be broken into pieces, and then the internal concrete glue will flow out and wrap the entire breaking structure and the inside of the limiting port 3. After solidification, the breaking structure can be fixed in the limiting port 3. At this time, two adjacent templates 1 are installed. In order to prevent the concrete glue from flowing out, a sloping groove 4 is specially provided at the bottom of the inlay ring 2. The sloping groove 4 slopes inward, and the glue passing through the inlay ring 2 will flow back along the sloping groove 4, and the inlay ring 2 itself can also prevent a large amount of glue from flowing out.

[0036] Among them, the buffer sleeve 6 and the buffer damping rod 7 play a role in slight shock absorption. The buffer shock absorption structure here directly purchases existing shock absorbers, so the specific structure will not be described in detail here. After assembly, only the installation joint 5, the buffer sleeve 6, the buffer damping rod 7, the connection head 8, and the push plate 9 are exposed between two adjacent templates 1. Among them, the push plate 9 will be attached to the surface of the limit port 3. The total length of the installation joint 5, the buffer sleeve 6, the buffer damping rod 7, the connection head 8, and the push plate 9 exposed outside is the safety distance reserved between two adjacent templates 1.

[0037] To sum up:

[0038] 1. The template 1 in this equipment is modular. Figure 1 As shown in one section of the template 1, during assembly, the components on the back of one section of the template 1 are inserted into the limit port 3 of another section of the template 1. The position of the limit port 3 on the front of the template 1 is aligned with the installation joint 5 on the back. The depth inside the limit port 3 is the same as the length of the connecting column 10 plus the tying head 11. At the same time, the diameter of the push plate 9 is larger than the diameter of the limit port 3, that is to say, the components on the back of the push plate 9 cannot enter the limit port 3. This can ensure that there will be a gap between adjacent templates 1, which is more practical.

[0039] 2. During actual use, lift two adjacent templates 1, and then insert the crushing structure on the back of one side template 1 into the corresponding limit port 3 on the front of the other side template 1. The tying head 11 will enter first and push the glass reservoir 13 from the fragile opening 14 into the interior of the limit port 3. When the back of the glass reservoir 13 hits the inner wall of the limit port 3, the glass reservoir 13 will exert a reverse force on the tying head 11. In this way, the tying head 11 will first crush the middle of the glass reservoir 13. After continuous extrusion, the entire glass reservoir 13 will be broken into pieces, and then the internal concrete glue will flow out and wrap the entire crushing structure and the interior of the limit port 3. After solidification, the crushing structure can be fixed in the limit port 3. At this time, two adjacent templates 1 are installed. In order to prevent the concrete glue from flowing out, a sloping groove 4 is specially provided at the bottom of the inlay ring 2. The sloping groove 4 slopes inward, and the glue passing through the inlay ring 2 will flow back along the sloping groove 4, and the inlay ring 2 itself can also prevent a large amount of glue from flowing out.
