Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete formwork, in particular to a local perspective formwork for concrete structures and a construction method. BACKGROUND

[0002] In the production process of concrete prefabricated parts (especially T-shaped, L-shaped and other special-shaped components), traditional steel or wooden formworks cannot be used to observe the internal concrete pouring state in real time due to the opaque material. Air bubbles are easily gathered and the vibration is uneven during pouring, which leads to internal cavities, insufficient density and affects the structural strength. The existing defoaming methods rely on manual vibration or external vibration equipment, but the efficiency of air bubble treatment for the edges and deep groove parts of the formwork is low. At the same time, the verticality of the assembled formwork needs to be repeatedly calibrated by additional tools, which is complicated. In view of the above problems, there is an urgent need for a formwork system that can visually monitor the pouring process, integrate air exhaust / defoaming function and facilitate verticality detection.

[0006] As an optimization, the side opposite to the formwork main body of the vibration plate is a smooth surface, and the height of the vibration plate is not less than the height of the formwork main body.

[0007] As an optimization, a plurality of vertical dovetail grooves are formed on the outer side of the formwork main body, and the plurality of dovetail grooves are distributed along the length direction of the formwork main body. A plurality of dovetail sliders are arranged on the side opposite to the vibration plate of the connecting seat, a jam nut is arranged in the middle of the connecting seat, and after the dovetail sliders are connected with the dovetail grooves, the jam nut is tightened to fix the position of the connecting seat.

[0008] As optimization, the upper side of the connecting seat is configured with a connecting arm connected with the fixed end of the telescopic assembly.

[0009] As optimization, when the adjacent template bodies are connected vertically, a detection part is detachably connected to the outer side of the template body, the detection part comprising a detection assembly, a first detection rod and a second detection rod arranged vertically, the first detection rod and the second detection rod being detachably connected with the two template bodies arranged vertically respectively, the detection assembly comprising two detection sleeves arranged vertically, the waist of the detection sleeve being rotationally connected with a limiting ring, the two limiting rings being fixedly connected.

[0010] As optimization, the inside of the detection sleeve is configured with a detection roller, the roller surface of the detection roller being in contact with the first detection rod or the second detection rod. The shaft center of the detection roller is perpendicular to the shaft center direction of the detection sleeve.

[0011] A construction method of a concrete structure local perspective template, used for making a T-shaped or L-shaped concrete prefabricated piece, specifically comprising the following steps: S1. Connecting the template: vertically connecting the transparent template to form a T-shaped or L-shaped prefabricated groove; S2. Connecting the detection part: connecting the detection part to the outer side of the two transparent templates arranged vertically, so that the first detection rod and the second detection rod are arranged vertically horizontally; S3. Pouring concrete: pouring concrete into the prefabricated groove formed in step S1, and observing the pouring situation; S4. Auxiliary defoaming: according to the observation in S3, if there are air bubbles in the concrete in the prefabricated groove, connecting the auxiliary exhaust part to the transparent template, and vibrating the concrete through the auxiliary exhaust part to defoam.

[0012] As optimization, the specific steps of auxiliary defoaming in step S4 are as follows: After the connecting seat is fixedly connected with the template body, the telescopic assembly is elongated, so that the back of the vibration plate is attached to the template body and moves downward until the auxiliary scraper is attached to the bottom of the prefabricated groove, and the concrete is vibrated through the vibration plate to defoam; After vibrating for a period of time, the telescopic assembly is shortened, driving the vibration plate and the auxiliary scraper upward, and the concrete is driven upward from bottom to top through the auxiliary scraper, so that the concrete at the bottom is sequentially lifted upward, the concrete close to the transparent template is reorganized, and the concrete at the inner side is sequentially attached to the inner side of the transparent template from bottom to top.

The retractable structure drives the vibration plate to move up and down in accordance with the formwork, covering different depth ranges. The auxiliary scraper with a bend at the bottom stirs the concrete during the lifting process, reorganizing the aggregate distribution, eliminating the risk of stratification and improving the interface density. The detection part is fixed to the vertical template through the first / second detection rod respectively. The built-in rolling component (detection roller) of the detection sleeve provides real-time feedback of angle deviation. The limit ring linkage structure ensures vertical synchronous calibration in both directions, reducing manual measurement links and improving installation accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
