Description

Technical Field

[0001] The present invention belongs to the technical field of engineering construction equipment, and particularly relates to a support system for the installation and removal of rectangular channel formwork and a construction method thereof. Background Art

[0002] Special drainage channels need to be constructed for farmland irrigation, domestic sewage disposal, and lake drainage, by digging ditches on the ground. After digging the ditches, in order to prevent problems such as water flow seepage and filter mud accumulation, a cement layer needs to be poured at the dug area to isolate the soil layer, which is convenient for cleaning the channel later. Existing water channels usually have a U-shaped cross-section, with the upper side being the open side, and the side corresponding to the ditch contact side is poured with cement and concrete.

[0003] The bottom of the water channel is a horizontal plane, and the pouring can be directly completed. However, the two sides of the water channel are inclined or vertical sides. When pouring, a support needs to be built to set up the formwork, and then the pouring is carried out. After the concrete is completely dry, the formwork is removed to complete the operation. The existing support system for channel design is relatively cumbersome and requires a large number of parts, which causes great inconvenience to the formwork installation and removal operations and affects the project progress. Summary of the Invention

[0004] The purpose of the present invention is to provide a support system for the installation and removal of rectangular channel formwork and a construction method thereof, so as to solve the problems of a large number of formworks, cumbersome engineering, and long construction period in the construction of existing ditches.

The sides of the formworks are aligned and spliced with each other. After alignment, adjacent formworks are fixed through the fitting system to form the supports on both sides of the sidewall formation layer. The formworks are square and plate-shaped. The side facing the sidewall formation layer on the front is a smooth side, and the back has reinforcing ribs; The support system includes a support frame for fixing the formwork system. The support frame includes a first crossbar and vertical bars. The upper ends of the vertical bars are perpendicularly fixed to the first crossbar, and the lower ends extend to the bottom of the sidewall formation layer. The vertical bars are located on the back side of the formwork, and the formwork and the vertical bars are fixed through the fastening system.

[0006] Further, the vertical bars corresponding to a single support frame are four parallel bars. Two are located inside the channel, and the other two are located outside the channel. A second crossbar is connected between the two inner vertical bars, and the second crossbar is parallel to the first crossbar.

[0007] The first crossbar has an extension section corresponding to the outer vertical bar. There is a diagonal brace between the end of the first crossbar and the outer vertical bar. After the diagonal brace is spliced and fixed with the first crossbar and the vertical bar, a right triangle is formed.

[0008] Furthermore, the template includes a first frame located at the side of the template and a cross-shaped second frame located inside the first frame. The first frame and the second frame are both double-layer plate rib structures, the two layers of plate ribs are parallel to each other, and have a first connecting block. A square frame is provided at the connection between the first frame and the second frame, a round tube reinforcement portion is provided inside the square frame, and a second connecting block is provided between the round tube reinforcement portion and the inner wall of the square frame.

[0009] The first frame has a positioning hole, and the accessory system includes a plastic pin for connecting adjacent templates through the positioning hole. The pin has an inserting portion inserted into the positioning hole and a handle fixed to the end of the inserting portion.

[0010] The construction method of the rectangular channel formwork installation and disassembly support system includes the following steps: (1) Dig a ditch according to the project requirements, pour concrete horizontally at the bottom of the ditch to form a channel concrete bottom plate, and wait for the concrete of the channel concrete bottom plate to dry; (2) The support system is built in sequence along the length direction of the formed channel concrete bottom plate, and the support frames corresponding to the support system are evenly and equidistantly arranged; (3) Build the formwork, align the gaps of the formwork along the vertical bars of the support frame in sequence, fix the adjacent formworks through the accessory system, form side wall casting grooves on both sides of the channel concrete bottom plate, and pour concrete; (4) After the concrete in the side wall casting trough has dried, remove the formwork and support frame in turn.

[0011] The present invention has the following beneficial effects: the channel formwork has a rapid installation and disassembly support process and has high production efficiency; the formwork and the support frame have light weight and can be directly installed upon arrival at the site; the labor intensity of the operators is low, which is conducive to civilized production and continuous production.

[0012] This system can replace the use of wooden formwork, which is beneficial to the protection of green plants. No construction machinery is required on site, which reduces energy loss.

[0013] This system does not require the installation of tension screws, reduces the plugging process after demolding, and improves the overall molding quality of the channel. BRIEF DESCRIPTION OF THE DRAWINGS
