Abstract
Description
Technical Field
[0001] The invention discloses a customized template for a plain concrete fire wall, which is used for customizing a plain concrete fire wall and belongs to the technical field of templates. Background Art
[0002] A concrete fire wall is a special building structure that is mainly used in facilities such as substations to provide fire resistance. The construction technology of this fire wall includes multiple aspects such as steel bar engineering, formwork engineering and concrete engineering.
[0003] In terms of steel bar engineering, the construction of firewalls needs to be carried out in strict accordance with relevant standards. For example, after the steel bars are brought into the site, they need to be tested for mechanical properties and can only be used after they pass the test. During the steel bar binding and installation process of the firewall, it is necessary to pay attention to the horizontal elevation, the outer dimension line of the firewall, and operate according to the standard construction process to ensure the construction quality.
[0004] In terms of formwork engineering, the formwork design of the firewall is very critical. At the construction site, the formwork is built according to the design drawings. This includes the positioning of the formwork, the installation of the support system, and the splicing between the formworks. The splicing needs to be carefully handled to prevent leakage. The stability of the formwork is very important to ensure that it will not move or deform during the concrete pouring process.
[0005] In terms of concrete engineering, pouring of fire walls is also an important link. For example, in the above-mentioned substation project, the pouring of the entire wall was carried out in five times, with each pouring a certain height to ensure the quality and uniformity of the concrete. In addition, in order to prevent leakage and improve the pouring effect, a series of measures were taken, such as wrapping the open seam strips with transparent tape and installing positioning steel bars.
[0006] In the prior art, the template used for the customization of plain concrete fire walls is a steel template. Although it can ensure the surface smoothness of the fire wall and avoid secondary processing, it still has the following technical problems:
[0007] 1. The manufacturing cost of steel formwork is high and its weight is heavy, which can easily cause installation difficulties;
[0008] 2. The thermal conductivity of steel formwork is high, which can easily affect the hardening process of concrete. Utility Model Content
[0009] The utility model aims to provide a customized template for a plain concrete fire wall, so as to solve the problem that the steel template has high manufacturing cost and heavy weight, thus making it difficult to install.
[0010] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0011] A custom-made template for a plain concrete fire wall, comprising a wooden template and a fixing structure for fixing the wooden template;
[0012] The wooden formwork comprises a side formwork A and another side formwork B which are arranged opposite to each other;
[0013] The side formwork A and the side formwork B respectively include an inner formwork and a back rib reinforcement structure matched with the inner formwork.
[0014] Furthermore, there are multiple inner templates in the side template A and the side template B, and each inner template cooperates with the corresponding back rib reinforcement structure.
[0015] Furthermore, the back rib reinforcement structure includes upper and lower transverse back ribs, left and right longitudinal back ribs matching the ends of the upper and lower transverse back ribs, and middle longitudinal back ribs arranged at equal intervals on the upper and lower transverse back ribs.
[0016] Furthermore, the back rib reinforcement structure also includes middle transverse back ribs which are arranged at equal intervals on the left longitudinal back rib, the right longitudinal back rib and the middle longitudinal back rib.
[0017] Furthermore, at the place where two adjacent back rib reinforcement structures cooperate, a T-shaped slide groove is arranged on the right longitudinal back rib of one back rib reinforcement structure, and a T-shaped sliding block cooperating with the T-shaped slide groove is arranged on the left longitudinal back rib of the other back rib reinforcement structure.
[0018] Furthermore, PE rubber cotton strips are arranged on the inner template where the two back rib reinforcement structures cooperate with each other.
[0019] Furthermore, in the side formwork A or the side formwork B, support blocks matching with the fixed structure are provided on the left longitudinal back rib of the back rib reinforcement structure at the left end and the right longitudinal back rib of the back rib reinforcement structure at the right end.
[0020] Furthermore, the fixing structure includes a square tube A which is arranged on the support block of the side formwork A or the side formwork B and has slide grooves at both ends, and a square tube B which is arranged on both ends of the two square tubes A. The square tube B is provided with a mounting part, and the mounting part is provided with a mounting hole corresponding to the slide groove. Bolts are provided on the slide groove and the mounting hole and cooperate with nuts.
[0021] Furthermore, the upper and lower ends of the side formwork A or the side formwork B are provided with tension holes;
[0022] The fixing structure also includes a plurality of channel steels, on which perforations corresponding to each group of tension holes are arranged. The relatively arranged side formwork A or side formwork B and the correspondingly arranged channel steels are fixed by tension screws passing through the perforations and the tension holes and nuts.
[0023] Compared with the prior art, the advantages of the utility model are:
[0024] 1. The inner formwork in the utility model cooperates with the corresponding back rib reinforcement structure to form the side formwork A or the side formwork B, and the side formwork A and the side formwork B cooperate to form a stable formwork system under the fixation of the fixed structure, which effectively prevents the formwork from being deformed or displaced during concrete pouring, ensures the verticality and horizontality of the fire wall, and improves the overall rigidity and strength of the formwork, thereby maintaining the shape and size of the formwork during concrete pouring, ensuring the smooth surface of the fire wall, and reducing quality problems such as honeycomb surface, while also avoiding the problems of high manufacturing cost, heavy weight and difficult installation of steel formwork. Since the thermal conductivity of the wooden formwork is much lower than that of the steel formwork, it is not easy to cause rapid changes in the internal temperature of the concrete, which helps to control the temperature and hardening speed of the concrete and reduce cracks and stress caused by temperature differences;
[0025] Second, the design of multiple inner templates in the utility model is convenient for quick installation and disassembly, which can speed up the construction progress and improve the construction efficiency;
[0026] 3.

[0027] Fourth, the purpose of setting the middle horizontal back rib in the utility model is to further enhance the overall stability of the back rib reinforcement structure;
[0028] 5. The design of the T-shaped slide and T-shaped slider of the utility model can ensure the close connection between the adjacent back rib reinforcement structures to form a stable side formwork A and side formwork B, and is conducive to rapid assembly and disassembly;
[0029] 6. The PE rubber cotton strip in the utility model has good sealing performance, which can fill the gap between the templates, prevent the loss of cement slurry during concrete pouring, and ensure the integrity and strength of the concrete structure;

[0031] 8. The fixing structure of the utility model can stably fix the wooden formwork through the combination of square tube A and square tube B, and the cooperation of bolts and nuts, thereby reducing the deformation and displacement of the wooden formwork during the concrete pouring process;
[0032] 9. The utility model can ensure the accurate position of the template in the vertical and horizontal directions by setting the tension holes and perforations and using tension screws and nuts for fixing, thereby improving the construction accuracy of the fire wall and the flatness of the wall surface.

The inner template in this embodiment is matched with the corresponding back rib reinforcement structure to form the side template A or side template B, and the side template A and the side template B are matched to form a stable template system under the fixation of the fixed structure, which effectively prevents the template from deforming or shifting during concrete pouring, ensures the verticality and horizontality of the fire wall, and improves the overall rigidity and strength of the template, so as to maintain the shape and size of the template during the concrete pouring process, ensure the smooth surface of the fire wall, reduce quality problems such as honeycomb surface, and avoid the problems of high manufacturing cost, heavy weight and difficult installation of steel templates. Since the thermal conductivity of the wooden template is much lower than that of the steel template, it is not easy to cause rapid changes in the internal temperature of the concrete, which helps to control the temperature and hardening speed of the concrete and reduce cracks and stress caused by temperature differences.

The purpose of providing the support blocks on the side formwork A or side formwork B is to facilitate the rapid installation of the fixed structure.

Under the condition that the square tube A18 and the square tube B19 are matched with the wooden template, the mounting hole 21 is made to correspond to the slide groove 17, and fixed by bolts and nuts. In this embodiment, the wooden template can be stably fixed by the combination of square tube A and square tube B, and the matching of bolts and nuts, reducing the deformation and displacement of the wooden template during the concrete pouring process.
