Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and specifically relates to an integrated device and construction method for wave pile cap beam formwork. Background Technology

[0002] A wave pile cap beam is a horizontal beam installed at the top of the wave piles to support, distribute, and transfer the load of the superstructure and connect the lower wave piles. During the construction of the wave pile cap beam, a wave pile cap beam formwork is required as a temporary support structure for the concrete pouring and shaping of the cap beam area, ensuring that the concrete reaches the expected shape and size to meet design requirements. Since wave piles often extend beyond the ground or water surface, the existing wave pile cap beam formwork often has formwork on the air-facing or water-facing side during cap beam construction. In actual use, the formwork in such working environments has poor stability, especially the bottom formwork on the air-facing or water-facing side is difficult to reinforce and support, making construction inconvenient. Insufficient stress between the formwork during grouting can easily lead to detachment, resulting in high construction risks.

[0003] In existing technologies, construction still relies on traditional formwork erection methods, which presents the aforementioned inconveniences and high risks. Some designs enhance stability by extensive welding or adding structural components, but these designs lead to difficulties in demolding and dismantling after construction, affecting the appearance of the wall, increasing construction costs, and hindering subsequent construction. Therefore, it is necessary to design an integrated wave pile cap beam formwork device and construction method to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an integrated device and construction method for wave pile cap beam formwork. The device solves the problems of difficult installation of formwork on the air-facing or water-facing side during the construction of existing wave pile cap beams, poor stability, and cumbersome and dangerous installation and dismantling procedures. It has the characteristics of stable structure, safety and reliability, simple layout, strong construction convenience, and easy subsequent demolding and dismantling.

[0006] Preferably, the rubber ring is a semi-flexible material rubber ring, and the rubber ring is set at the connection between the bottom mold and the wave pile, with one ring set along the edge of the bottom mold.

[0007] Preferably, the transverse tensioning device includes two sets of square steel. One end of the square steel is inserted into the support at the top of the side mold, and the insertion is connected by a pin. The other end of the square steel is connected to a single-ear fixing member, which is connected to a wire rope tensioner. The wire rope tensioner connects the two sets of square steel together.

[0008] Preferably, the side surface of the square steel is connected to an ear seat and an upwardly inclined tensioning device.

[0011] Preferably, the upward-sloping tensioning device is inclined inward; an upward-sloping tensioning device is provided below each group of horizontal tensioning devices; multiple upward-sloping tensioning devices are arranged alternately.

[0012] Preferably, the side molds are connected by pins and holes to form a continuous template.

[0013] Furthermore, both the bottom mold and the side mold are made of aluminum, which is lightweight, allows for quick demolding, and facilitates subsequent demolding and turnover.

[0014] Preferably, the construction method of the above-mentioned integrated formwork device for wave pile cap beam includes the following steps:

[0015] S1, construct the cap beam reinforcement cage and the cap beam reinforcement cage protective layer on top of the wave pile;

[0016] S2, construct the integrated device on top of the wave pile; process the bottom formwork to the same curvature as the outer surface of the wave pile, and weld the side formwork to the edge of the bottom formwork; weld angle steel to the outer surface of the joint between the bottom formwork and the side formwork to enhance the rigidity of the L-shaped formwork;

[0017] S3, the bottom mold is laid along the outer surface of the wave pile, and rubber rings are installed along the joints to seal and enhance the friction with the wave pile;

[0018] S4. The templates formed by welding multiple bottom and side molds are connected laterally by pins to form an integral template, and then matched with the wave piles in accordance with the method in S3.

[0019] S5, connect the horizontal tensioning devices on both sides of the top of the side formwork and tighten the side formwork on both sides, so that the square steel at the top of the side formwork is supported on the protective layer of the cap beam steel cage and bears the load of the entire formwork system; then connect the upward tensioning device with the horizontal tensioning device and adjust the wire rope to tighten the bottom formwork and the side formwork.

[0020] S6. Grouting is performed inside the assembled template, with the PVC pipes remaining inside the concrete during grouting.

When in use, the stress between the bottom mold and the side mold is evenly distributed through the transverse tensioning device and multiple staggered upward tensioning devices, so that the bottom mold and the side mold are evenly stressed and not easy to overturn, which greatly improves safety.

[0023] 2. A rubber ring is provided at the edge of the bottom mold to effectively prevent the mold from sliding and grout leakage at the joints;

[0024] 3. The base plate is equipped with an upwardly inclined fastening device in the middle, and the top of the template is equipped with two sets of horizontal tensioning devices. Angle steel is installed between the base plate and the template, which improves the practicality and stability of the template.

[0025] 4. The template has a split structure, and multiple templates can be quickly disassembled using pins. The horizontal tensioning device at the top of the template can also be easily disassembled and reused, resulting in rapid demolding. The overall template has a high number of reuses, is not easily deformed, is safe to use, and can effectively improve the quality of subsequent concrete surface forming. Attached Figure Description
