Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a concrete pouring template for post-cast grooves of highway expansion joints. Background Technology

[0002] With the rapid development of urban construction, various transportation facilities have advanced by leaps and bounds. Highways, elevated roads, and various types of bridges have been built one after another. Due to the continuous increase in vehicle traffic volume, speed, and load, as well as some minor issues left over from bridge construction, damage to bridge expansion joints is very common. Damage to these joints causes vehicles to experience excessive bumps and vibrations, noise pollution, and exacerbates the jarring and jolting sensation, while also jeopardizing bridge safety, extending its service life, and increasing maintenance costs. Therefore, the durability, ride comfort, and passenger comfort of bridges have become a major concern for design and construction departments.

[0003] Chinese Utility Model Patent Publication No. CN 221645587 U discloses a concrete pouring mold for post-cast grooves of expansion joints in highway bridges. The specification of this mold states that it includes a mold body, a drive assembly, and a positioning assembly. The mold body comprises a left mold and a right mold, which abut against the two sides of the expansion joint to provide pouring space for the post-cast groove. The drive assembly includes a hydraulic jack positioned between the left and right molds, which presses them firmly against the two sides of the expansion joint to prevent mold detachment and displacement during construction, thus improving installation accuracy. The positioning assembly is located on the mold body to further improve installation accuracy and the quality of the post-cast groove concrete pouring. However, this concrete pouring mold for post-cast grooves of expansion joints in highway bridges lacks an adjustment structure, relying solely on bolt holes in the upper and lower sliding plates for adjustment. This relatively simple adjustment method cannot accommodate different construction scenarios and has poor practicality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a concrete pouring template for the post-cast groove of highway expansion joints, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a concrete pouring template for a highway expansion joint, including a bridge deck and a pouring template body located inside the bridge deck. A pouring groove is provided between adjacent bridge decks. A positioning groove is provided at the bottom of the pouring groove near the end of the pouring template body. A protrusion is fixedly installed at the end of the pouring template body near the pouring groove. A first support component is fixedly installed at the corner of the pouring template body. A second support component is provided between the pouring template body and the bridge deck.

[0006] Preferably, the cross-section of the protrusion is the same as the cross-section of the positioning groove, and the protrusion can be inserted into the positioning groove.

[0007] The above technical solution, with the cross-section of the protrusion being the same as that of the positioning groove and the protrusion being able to be inserted into the positioning groove, facilitates the quick positioning and installation of the casting template body inside the casting groove, avoiding template misalignment. At the same time, by inserting the protrusion into the positioning groove, the connection stability between the template and the casting groove is enhanced, preventing template displacement due to lateral pressure during concrete pouring, and ensuring the dimensional accuracy and forming quality of the concrete pouring in the expansion joint post-cast groove.

[0008] Preferably, the first support assembly includes a fixed plate, a turntable is provided inside the fixed plate, a rotating shaft fixedly connected to the fixed plate is rotatably mounted on the inner surface of the turntable, a first limiting hole is provided on the side of the fixed plate, a second through-hole is provided on the side of the turntable, a limiting pin is provided on the side of the fixed plate away from the turntable, a fixed rod is fixedly mounted on one end of the turntable, an extension rod is provided on the side of the fixed rod away from the turntable, a support block is rotatably mounted on the end of the extension rod away from the fixed rod, a plurality of sets of third limiting holes are provided at equal intervals on the outer surface of the fixed rod, a return spring is fixedly mounted on the inner wall of the extension rod, and a limiting rod is fixedly mounted on the end of the return spring away from the extension rod.

[0009] The above technical solution includes a first support component that is connected to the fixed plate by rotation. The direction of the fixed rod can be adjusted according to different installation angle requirements, making it suitable for different construction scenarios.

[0010] Preferably, the radius of the limiting pin is the same as the radius of the limiting hole one and the limiting hole two. The limiting pin can be inserted into the limiting hole one and the limiting hole two at the same time. The limiting hole one and the limiting hole two are provided with several identical sets. The several sets of the limiting hole one and the limiting hole two are located on the fixed plate and the turntable in a ring distribution. The cross-section of the support block has an "L" shaped structure.

[0011] Through the above technical solution, the limiting pin can be inserted into the limiting hole one and the limiting hole two at the same time, which can lock the turntable at multiple angle positions, ensuring that the fixing rod remains stable after being adjusted to the appropriate angle. Furthermore, by setting the cross-section of the support block to be "L" shaped, it is easy to fit with the bridge deck, ensuring the stability of the casting template body during pouring.

[0012] Preferably, the radius of the limiting rod is the same as the radius of the limiting hole three, and the fixing rod and the extension rod are slidably connected.

[0013] With the above technical solution, the radius of the limiting rod is the same as the radius of the limiting hole three, and the fixed rod and the extension rod are slidably connected, which facilitates the length adjustment of the fixed rod and the extension rod. During adjustment, the operator only needs to manually squeeze the limiting rod to the inner surface of the fixed rod, and then the length can be flexibly adjusted. When adjusted to the appropriate position, simply release the finger, and the limiting rod will re-lock into the limiting hole three under the elastic action of the return spring, thus realizing the quick locking of the fixed rod and the extension rod. This solution is suitable for different construction scenarios.

[0014] Preferably, the second support assembly includes a support rod, a screw is provided on the side of the support rod away from the casting template body, an extrusion block one is fixedly installed on the end of the screw away from the support rod, and an extrusion block two is rotatably installed on the end of the support rod away from the screw.

[0015] Preferably, the support rod and the screw are connected by a thread, and the outer surface of the support rod is provided with several sets of anti-slip grooves at equal intervals.

[0016] The above technical solution, through the threaded connection between the support rod and the screw, allows for flexible adjustment and reliable support of the gap between the casting template and the bridge deck. This effectively disperses the pressure on the template during concrete pouring, enhances the tightness and stability of the connection between the template and the bridge deck, prevents template deformation or displacement, and ensures pouring quality. Furthermore, by equally spaced anti-slip grooves on the outer surface of the support rod, the friction between the operator's hand and the support rod is increased, making it easier and more stable to hold and rotate the support rod during installation and adjustment, preventing slippage, and improving operational convenience and construction efficiency.

[0017] Compared with the prior art, this utility model provides a concrete pouring template for post-cast grooves of highway expansion joints, which has the following beneficial effects: 1. This concrete pouring template for the post-cast groove of the highway expansion joint is connected to the fixed plate by a turntable. The direction of the fixed rod can be adjusted according to different installation angle requirements. The limit pin can be inserted into the limit hole one and limit hole two at the same time, which can lock the turntable at multiple angle positions and ensure that the fixed rod remains stable after being adjusted to the appropriate angle. It is suitable for different construction scenarios. 2. The concrete pouring formwork for the post-construction trough of the highway expansion joint features a threaded connection between the support rods and screws. This design allows for flexible adjustment and reliable support of the gap between the formwork and the bridge deck, effectively dispersing the pressure on the formwork during concrete pouring, enhancing the tightness and stability of the connection between the formwork and the bridge deck, preventing formwork deformation or displacement, and ensuring pouring quality. Furthermore, the presence of several sets of anti-slip grooves at equal intervals on the outer surface of the support rods increases the friction between the operator's hands and the support rods, making it easier and more stable to hold and rotate the support rods during installation and adjustment, preventing slippage, and improving operational convenience and construction efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: As Figure 1-6 As shown, the present invention provides a concrete pouring template for a highway expansion joint, including a bridge deck 1 and a pouring template body 4 located inside the bridge deck 1. A pouring groove 2 is provided between adjacent bridge decks 1. A positioning groove 3 is provided at the bottom of the pouring groove 2 near the end of the pouring template body 4. A protrusion 5 is fixedly installed at the end of the pouring template body 4 near the pouring groove 2. A first support component 6 is fixedly installed at the corner of the pouring template body 4. A second support component 7 is provided between the pouring template body 4 and the bridge deck 1.

[0022] Specifically, the cross-section of the protrusion 5 is the same as the cross-section of the positioning groove 3, and the protrusion 5 can be inserted into the positioning groove 3. The advantage is that, because the cross-section of the protrusion 5 is the same as the cross-section of the positioning groove 3, and the protrusion 5 can be inserted into the positioning groove 3, it facilitates the quick positioning and installation of the casting template body 4 inside the casting groove 2, avoiding template misalignment. At the same time, by inserting the protrusion 5 into the positioning groove 3, the connection stability between the template and the casting groove 2 is enhanced, preventing template displacement due to lateral pressure during concrete pouring, and ensuring the dimensional accuracy and molding quality of the concrete poured after the expansion joint.

[0023] Specifically, the first support component 6 includes a fixed plate 601, a turntable 602 is provided inside the fixed plate 601, a rotating shaft 603 fixedly connected to the fixed plate 601 is rotatably mounted on the inner surface of the turntable 602, a limiting hole 604 is provided on the side of the fixed plate 601, a through-type limiting hole 605 is provided on the side of the turntable 602, a limiting pin 606 is provided on the side of the fixed plate 601 away from the turntable 602, a fixed rod 607 is fixedly mounted on one end of the turntable 602, an extension rod 608 is provided on the side of the fixed rod 607 away from the turntable 602, a support block 609 is rotatably mounted on the end of the extension rod 608 away from the fixed rod 607, a number of sets of limiting holes 610 are provided at equal intervals on the outer surface of the fixed rod 607, a return spring 611 is fixedly mounted on the inner wall of the extension rod 608, and a limiting rod 612 is fixedly mounted on the end of the return spring 611 away from the extension rod 608. The advantage is that the first support component 6 is set up, which is connected to the fixed plate 601 by the rotation of the turntable 602. The direction of the fixed rod 607 can be adjusted according to different installation angle requirements, making it suitable for different construction scenarios.

[0024] Specifically, the radius of the limiting pin 606 is the same as the radius of the limiting hole 604 and the limiting hole 605. The limiting pin 606 can be inserted into both the limiting hole 604 and the limiting hole 605 simultaneously. Both the limiting hole 604 and the limiting hole 605 have several identical sets, which are arranged in a ring on the fixing plate 601 and the turntable 602. The support block 609 has an "L"-shaped cross-section. The advantage is that by allowing the limiting pin 606 to be inserted into both the limiting hole 604 and the limiting hole 605 simultaneously, multiple angular positions of the turntable 602 can be locked, ensuring the stability of the fixing rod 607 after adjustment to a suitable angle. Furthermore, the "L"-shaped cross-section of the support block 609 facilitates its fit with the bridge deck 1, ensuring the stability of the casting template body 4 during pouring.

[0025] Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.

[0026] Specifically, the radius of the limiting rod 612 is the same as the radius of the limiting hole 610, and the fixing rod 607 and the extension rod 608 are slidably connected. The advantage is that, because the radius of the limiting rod 612 is the same as the radius of the limiting hole 610, and the fixing rod 607 and the extension rod 608 are slidably connected, the length of the fixing rod 607 and the extension rod 608 can be easily adjusted. During adjustment, the operator only needs to manually squeeze the limiting rod 612 to the inner surface of the fixing rod 607, and then the length can be flexibly adjusted. When adjusted to the appropriate position, simply release the finger, and the limiting rod 612, under the elastic action of the return spring 611, will re-lock into the limiting hole 610, thus achieving quick locking of the fixing rod 607 and the extension rod 608. This is suitable for different construction scenarios.

[0027] Specifically, the second support component 7 includes a support rod 701, a screw 702 is provided on the side of the support rod 701 away from the casting template body 4, an extrusion block 703 is fixedly installed on the end of the screw 702 away from the support rod 701, and an extrusion block 704 is rotatably installed on the end of the support rod 701 away from the screw 702.

[0028] Specifically, the support rod 701 and the screw rod 702 are threaded together, and several sets of anti-slip grooves 705 are evenly spaced on the outer surface of the support rod 701. The advantages are that the threaded connection between the support rod 701 and the screw rod 702 facilitates flexible adjustment and reliable support of the gap between the casting template body 4 and the bridge deck 1, effectively dispersing the pressure on the template during concrete pouring, enhancing the tightness and stability of the connection between the template and the bridge deck 1, preventing template deformation or displacement, and ensuring pouring quality. Furthermore, the evenly spaced anti-slip grooves 705 on the outer surface of the support rod 701 increase the friction between the operator's hand and the support rod 701, making it easier and more stable to hold and rotate the support rod 701 during installation and adjustment, preventing slippage, and improving operational convenience and construction efficiency.

[0029] Working principle: In use, the cross-section of the protrusion 5 is the same as the cross-section of the positioning groove 3, allowing the casting template body 4 to be quickly positioned and installed inside the casting groove 2, preventing template misalignment. Simultaneously, by engaging the protrusion 5 within the positioning groove 3, the connection stability between the template and the casting groove 2 is enhanced, preventing template displacement due to lateral pressure during concrete pouring, thus ensuring the dimensional accuracy and molding quality of the concrete poured after the expansion joint. Subsequently, the turntable 602 is rotated and connected to the fixing plate 601, allowing for adjustments based on different installation angle requirements. By adjusting the direction of the fixing rod 607, and simultaneously inserting the limiting pin 606 into both the first limiting hole 604 and the second limiting hole 605, multiple angular positions of the turntable 602 can be locked, ensuring the stability of the fixing rod 607 after adjustment to the appropriate angle. The support block 609 has an "L"-shaped cross-section, facilitating its fit with the bridge deck 1. Furthermore, the radius of the limiting rod 612 is the same as the radius of the third limiting hole 610, and the fixing rod 607 and the extension rod 608 are slidably connected, allowing for easy connection between the fixing rod 607 and the extension rod 608. For length adjustment, workers simply need to manually squeeze the limiting rod 612 to the inner surface of the fixing rod 607, and then flexibly adjust the length until the support block 609 is tightly fitted with the bridge deck 1. Releasing the finger allows the limiting rod 612 to re-engage into the limiting hole 610 under the elastic action of the return spring 611, thus quickly locking the fixing rod 607 and the extension rod 608. This is suitable for different construction scenarios. Finally, the threaded connection between the support rod 701 and the screw 702 facilitates the connection between the casting template body 4 and the bridge deck. The gap between the beam bridge deck 1 is flexibly adjustable and reliably supported, effectively dispersing the pressure on the formwork during concrete pouring, enhancing the tightness and stability of the connection between the formwork and the bridge deck 1, preventing formwork deformation or displacement, ensuring pouring quality, and increasing the friction between the operator's hand and the support rod 701 by equally spaced anti-slip grooves 705 on the outer surface of the support rod 701, making it easier and more stable to hold and rotate the support rod 701 during installation and adjustment, avoiding slippage, and improving operational convenience and construction efficiency.
