Description

Technical Field

[0001] This utility model relates to a hydraulic climbing formwork for concrete pouring, specifically a hydraulic climbing formwork for preventing grout leakage during concrete pouring. Background Technology

[0002] Hydraulic climbing formwork is a modern construction technology widely used in the construction of tall structures such as high-rise buildings and bridges. A typical hydraulic climbing formwork system includes a climbing device, a retraction device, and formwork. The climbing device usually includes a climbing formwork frame and climbing cylinders, used to alternately lift the formwork and the climbing frame. The retraction device is usually installed on the climbing formwork frame and connected to the formwork, used to move the formwork backward. During construction, the climbing device lifts the formwork upward, positioning its bottom between the already poured concrete surface and the surface to be poured. Then, the concrete to be poured is poured from the inside of the formwork.

[0003] However, during the pouring of concrete, the concrete may leak from the bottom of the formwork onto the already poured concrete surface, negatively impacting its appearance. Current techniques involve pre-installing a section of formwork tightly against the already poured concrete surface and then applying foam sealant to the gap between the formwork and the surface to prevent leakage. However, this method often proves ineffective, and the foam sealant adheres to the joint between the two surfaces, resulting in poor flatness and requiring subsequent grinding, thus increasing the workload. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problems and provides a hydraulic climbing formwork for concrete pouring that prevents the poured concrete from flowing out from the bottom of the formwork onto the surface of the poured concrete, and does not affect the flatness of the joint between the surface of the poured concrete and the surface of the concrete to be poured.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A hydraulic climbing formwork for concrete pouring with leak-proof grouting includes a rearward movement device, an upright connected to the rearward movement device, and a template connected to the upright via a back brace. The hydraulic climbing formwork also includes a leak-proof grouting assembly, which includes a mounting base, a seal, a fixing nut, and an adjusting screw. The mounting base is fixed to the bottom of the template. The seal is mounted on the mounting base and has a sealing portion that contacts the bottom of the template. The fixing nut is fixedly connected to the upright. The adjusting screw movably passes through the upright and is threadedly connected to the fixing nut. When subjected to force, the adjusting screw can rotate relative to the fixing nut, causing it to move towards the mounting base and press against it, thus ensuring that the sealing portion maintains a sealed contact with the poured concrete surface.

[0007] Furthermore, the adjusting screw includes a screw section and several stiffening ribs. The screw section is movably inserted through the upright and threadedly connected to the fixing nut. The several stiffening ribs are fixed to one end of the screw section near the mounting base and are spaced apart circumferentially along the screw section. The one end of the screw section near the mounting base and the several stiffening ribs can abut against the mounting base.

[0008] Furthermore, the stiffening rib is a triangular stiffening rib.

[0009] Furthermore, the screw portion is perpendicular to the upright.

[0010] Furthermore, the upright is provided with an insertion hole, and the screw portion movably passes through the insertion hole.

[0011] Furthermore, the fixing nut is fixed to the side of the upright facing away from the template.

[0012] Furthermore, the mounting base is provided with a mounting groove, which extends through the side of the mounting base opposite to the adjusting screw to form an opening; the sealing element is detachably installed in the mounting groove and one side protrudes out of the mounting base through the opening to form the sealing portion.

[0013] Furthermore, the mounting base is made of channel steel and includes a base plate and two side plates respectively fixed to opposite sides of the base plate. The two side plates and the base plate surround to form the mounting groove, and the side of the two side plates away from the base plate surrounds to form the opening.

[0014] Furthermore, the seal is made of elastic rubber.

[0015] Furthermore, the top surface of the sealing part contacts the bottom of the template, and the side of the sealing part away from the upright extends between the template and the poured concrete surface.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. The aforementioned anti-leakage hydraulic climbing formwork for concrete pouring uses a support structure composed of a mounting base, adjusting screw, and fixing nut to fix the sealing element to the bottom of the formwork. During formwork installation, the formwork is moved into place by the rearward moving device, and the sealing element is squeezed tightly against the poured concrete surface, thus achieving the purpose of preventing concrete leakage and protecting the poured concrete surface. After construction is completed, the sealing element can be separated from the poured concrete surface by moving the formwork backward by the rearward moving device, without affecting the flatness of the joint between the poured concrete surface and the concrete surface to be poured.

[0018] 2. The above-mentioned anti-leakage hydraulic climbing formwork for concrete pouring has an adjusting screw connected to the upright of the hydraulic climbing formwork via a fixing nut. After the rearward device moves the formwork into place, the supporting force of the adjusting screw on the mounting base can be adjusted by rotating the adjusting screw to ensure that the sealing element always maintains a sealed contact with the poured concrete surface.

[0019] 3. The above-mentioned anti-leakage hydraulic climbing formwork for concrete pouring has an adjusting screw consisting of a screw section and several stiffening ribs. In use, the screw section and several stiffening ribs simultaneously support the side of the mounting base facing away from the concrete surface to be poured, which can prevent the mounting base from being damaged due to concentrated force.

[0020] 4. The aforementioned anti-leakage hydraulic climbing formwork for concrete pouring uses elastic rubber seals for superior sealing performance. Furthermore, the seals are inserted into the mounting grooves of the mounting base, allowing for easy replacement when worn. Attached Figure Description

This part belongs to the prior art and will not be described in detail here for the sake of brevity.

[0029] In this embodiment, the anti-leakage hydraulic climbing formwork 100 for concrete pouring also includes an anti-leakage component 60. The anti-leakage component 60 includes a mounting base 61, a sealing element 62, a fixing nut 63, and an adjusting screw 64. The mounting base 61 is fixed to the bottom of the formwork 50; the sealing element 62 is mounted on the mounting base 61 and has a sealing portion 621 that contacts the bottom of the formwork 50; the fixing nut 63 is fixedly connected to the upright 30; and the adjusting screw 64 movably passes through the upright 30 and is threadedly connected to the fixing nut 63. When the adjusting screw 64 is subjected to force, it can rotate relative to the fixing nut 63, thereby moving the adjusting screw 64 towards the mounting base 61 and pressing it against the mounting base 61, so that the sealing portion 621 maintains a sealed contact with the poured concrete surface 200.

[0030] In this embodiment, the mounting base 61 is provided with a mounting groove 611, which passes through one side of the mounting base 61 opposite to the adjusting screw 64 to form an opening 612. Specifically, the mounting base 61 is made of channel steel and includes a base plate 613 and two side plates 614 respectively fixed to opposite sides of the base plate 613. The side plates 614 and the base plate 613 surround the mounting groove 611, and the side of the side plates 614 away from the base plate 613 surrounds the opening 612 communicating with the mounting groove 611. The top surface of one side plate 614 is fixed to the bottom of the template 50 by welding. In this embodiment, the seal 62 is made of elastic rubber. The seal 62 is detachably inserted into the mounting groove 611 and one side protrudes from the mounting base 61 through the opening 612 to form the sealing part 621. The top surface of the sealing part 621 contacts the bottom of the template 50, and the side of the sealing part 621 away from the upright 30 extends between the template 50 and the concrete surface 200 to be poured.

[0031] In this embodiment, the fixing nut 63 is fixed to the side of the upright 30 facing away from the template 50. The adjusting screw 64 includes a screw part 641 and several stiffening ribs 643. The screw part 641 is perpendicular to the upright 30, and the screw part 641 movably passes through the upright 30 and is threadedly connected to the fixing nut 63. Specifically, the upright 30 is provided with an insertion hole 31, and the screw part 641 movably passes through the insertion hole 31. Several stiffening ribs 643 are fixed to one end of the screw part 641 near the mounting base 61 and are spaced apart along the circumference of the screw part 641. The end of the screw part 641 near the mounting base 61 and the several stiffening ribs 643 can abut against the base plate 613 of the mounting base 61. In this embodiment, the stiffening ribs 643 are triangular stiffening ribs.

[0032] The anti-leakage hydraulic climbing formwork 100 for concrete pouring uses a bracket structure composed of mounting base 61, adjusting screw 64 and fixing nut 63 to fix the sealing element 62 to the bottom of the formwork 50. In use, after the formwork 50 is moved into place closer to the concrete surface 300 to be poured by the rearward moving device 20, the sealing element 62 is squeezed and pressed tightly against the poured concrete surface 200, which can seal the gap between the bottom of the formwork 50 and the poured concrete surface 200, preventing concrete leakage to the poured concrete surface 200. After construction is completed, the sealing element 62 can be separated from the poured concrete surface 200 by moving the formwork 50 backward by the rearward moving device 20, without affecting the flatness of the joint between the poured concrete surface 200 and the concrete surface 300 to be poured.

[0033] The aforementioned anti-leakage hydraulic climbing formwork 100 for concrete pouring has an adjusting screw 64 connected to the upright 30 of the hydraulic climbing formwork via a fixing nut 63. After the retraction device 20 moves the formwork 50 into place, the adjusting screw 64 can be rotated to adjust the supporting force of the adjusting screw 64 on the mounting base 61, ensuring that the sealing element 62 always maintains a sealed contact with the poured concrete surface 200.

[0034] The aforementioned anti-leakage hydraulic climbing formwork 100 for concrete pouring includes an adjusting screw 64 comprising a screw part 641 and several stiffening ribs 643. In use, the screw part 641 and several stiffening ribs 643 simultaneously support the side of the mounting base 61 facing away from the concrete surface 300 to be poured, thus preventing damage to the mounting base 61 due to concentrated force.

[0035] The aforementioned anti-leakage hydraulic climbing formwork 100 for concrete pouring uses elastic rubber for the sealing element 62, resulting in a better sealing effect. Furthermore, the sealing element 62 is inserted into the mounting groove 611 of the mounting base 61, allowing for easy replacement when the sealing element 62 becomes worn.

[0036] It is understood that the aforementioned anti-leakage hydraulic climbing formwork 100 for concrete pouring may also include other components, which are existing technologies, such as climbing cylinders, etc., which will not be described in detail here for the sake of brevity.
