Description

Technical Field

[0001] This utility model relates to the field of casting template structure technology, specifically a construction structure for casting templates for energy storage and protection foundations. Background Technology

[0002] When protecting the integrated chemical energy storage tank with a wall, it is necessary to pour reinforced concrete to create a column in the middle of the wall. Before pouring, the foundation part of the column, which is located at the bottom of the excavated trench, needs to be constructed with a formwork structure to create the pouring space.

[0003] Furthermore, the application document with publication number CN220927857U mentions the construction structure of the energy storage protection foundation pouring formwork. The back of the formwork is supported by steel bars embedded in the solidified pile body. The steel bars are firmly supported by the poured and solidified pile body, so that the four formworks can create a pouring space around the column steel bars. This solves the problem that the inclined support rods cannot obtain firm support and force to support the back of the formwork to construct the formwork construction structure for pouring the column. However, there are still some defects that need to be optimized. The specific defects are as follows: The structure is simply enclosed by four independent formworks. There is a lack of effective lateral tie and vertical locking between the formworks. During the concrete pouring process, problems such as formwork displacement and joint expansion are prone to occur, which affect the molding quality and pose safety hazards. At the same time, there is a lack of fast and accurate positioning mechanism, resulting in low formwork installation efficiency and difficulty in ensuring the overall verticality of the assembled multiple formworks.

[0004] Therefore, there is an urgent need to design a construction structure for the energy storage protection foundation casting formwork that can solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a construction structure for a casting template for an energy storage and protective foundation. To achieve the above objective, this utility model provides the following technical solution:

[0006] A construction structure for a pouring formwork of an energy storage protective foundation includes a poured and solidified pile body, a pre-embedded steel bar segment in the poured and solidified pile body, a portion of the steel bar segment being exposed outside the poured and solidified pile body, a column steel bar at the center of the poured and solidified pile body, and a protective structure along the outer edge of the column steel bar, the protective structure and the column steel bar forming a pouring space, and the end of the exposed steel bar segment abutting against the outer side of the protective structure.

[0007] Furthermore, the protective structure includes a set of base protection components and several assembled protection components. The base protection components include four first L-shaped enclosures, each of which has an upward-facing slot on its top surface. The side of the four first L-shaped enclosures away from the column reinforcement is connected to a back rib plate by screws. Each assembled protection component includes four second L-shaped enclosures, each of which has a positioning block on its bottom surface that is adapted to the slot.

[0008] Furthermore, each of the first L-shaped enclosure and the second L-shaped enclosure is provided with a slot, and the four first L-shaped enclosures and the four second L-shaped enclosures fit together with each other. Each first L-shaped enclosure and the second L-shaped enclosure is provided with a limiting component, and the top of the limiting component is provided with a positioning component.

[0009] The above technical solution enables precise positioning and rapid connection of the upper and lower L-shaped panels, ensuring that the upper and lower layers are not misaligned or misaligned, thereby guaranteeing the verticality and flatness of the columns.

[0010] Furthermore, the limiting component includes a threaded cylinder disposed on the shorter side of the first L-shaped enclosure and the second L-shaped enclosure, the threaded cylinder having a threaded rod inside, the threaded rod being connected to a limiting ring, the limiting ring being connected to a steel cable, and a fixing ring for fitting the steel cable being disposed on the other side of the first L-shaped enclosure and the second L-shaped enclosure.

[0011] The above technical solution uses a threaded rod to tighten the steel cable, which tightly "binds" the four L-shaped panels together from the outside, forming a whole and resisting the outward expansion force of the concrete.

[0012] Furthermore, each of the first L-shaped panels has a connecting seat symmetrically provided at its top end, and each of the second L-shaped panels has a fixing seat symmetrically provided at its top end. The fixing seat and the connecting seat are provided with through holes, and the inside of the through holes is provided with positioning rods. The two ends of the positioning rods are respectively provided with threads.

[0013] The above technical solution is used to connect the upper and lower L-shaped panels, fixing them into a whole and preventing the upper layer from shifting or floating during the pouring process.

[0014] Furthermore, elastic sealing strips are provided on the joint surfaces between the first L-shaped enclosure and the second L-shaped enclosure, and between several first L-shaped enclosures and second L-shaped enclosures. A cement mortar leveling layer is laid between the bottom end of the base protection component and the top surface of the poured and solidified pile body.

[0015] Through the above technical solution, the elastic sealing strip is filled in all horizontal and vertical joints between the L-shaped panels. Under pressure, it is compressed to effectively prevent liquid cement slurry from leaking from the joints, ensuring the aesthetics of the column surface and the quality of the pouring. The cement mortar leveling layer is filled in the gap between the bottom formwork and the top surface of the poured pile to prevent concrete from leaking out from the root and causing the "rotten root" phenomenon.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this utility model, the following effects can be achieved by setting up a construction structure for energy storage protective foundation pouring template: 1. By setting up a fastening system composed of limiting components and positioning components, multiple L-shaped partitions can be firmly connected in the horizontal and vertical directions into a rigid integral spatial structure, effectively resisting the lateral pressure of concrete, preventing template deformation and displacement, and significantly improving construction safety and forming quality; 2. By adopting the method of stacking and combining base protection components with multiple assembled protection components, the number of assembly layers can be flexibly increased or decreased according to the design height of the column; 3. By utilizing the mortise and tenon joint of the slot and positioning block, as well as the mutual fitting of the slots, rapid and accurate positioning between upper and lower layers and between the same layer of templates is achieved, greatly improving installation efficiency and effectively ensuring the verticality and flatness of the template after assembly.
