Description

Technical Field

[0001] This utility model relates to the field of concrete formwork technology, specifically a splicing UHPC concrete formwork. Background Technology

[0002] UHPC concrete formwork is a type of building formwork made of ultra-high performance concrete material. It is used as the outer shell of formwork in concrete structure construction. Because this formwork has ultra-high strength, high durability, excellent toughness and low permeability, it is an advanced cement-based composite material and is widely used in bridges, high-rise buildings, marine engineering and other fields. When concrete is poured on site, most existing concrete formworks are used as one-piece formworks. However, one-piece formworks cannot be disassembled and used at the same time as pouring, which can lead to deformation and damage of the formed concrete, reducing the efficiency of the concrete formwork.

[0003] To overcome the above-mentioned defects, in the prior art 1 (Chinese patent application number CN202021398596.2, application date 2020-07-16), a formwork-free concrete wall formwork is provided. The formwork shells are connected by screws. At the same time, the bonding performance between the formwork shell and the concrete wall can be improved by adding a rough surface on the inner surface of the formwork shell in contact with the concrete. This achieves formwork-free installation, reliable connection between the formwork shell and the concrete wall, and lifespan as long as the structure. Although the prior art can achieve quick disassembly and replacement of the formwork shell, making the operation more time-saving and labor-saving, it cannot adjust the pouring space during actual pouring production. It can only be used for pouring with formwork shells of the same size, which leads to poor practicality of the formwork shell and reduces the efficiency of later pouring. Therefore, the splicing UHPC concrete formwork shell is proposed, which can effectively solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a splicing UHPC concrete formwork shell to solve the problem mentioned in the background art that the formwork shells currently on the market cannot adjust the pouring space during actual pouring production, and can only be used for pouring of formwork shells of the same size, which leads to poor practicality of the formwork shell and reduces the efficiency of later pouring.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular UHPC concrete formwork, comprising a formwork body, wherein vent holes for venting gas are symmetrically opened on both sides of the formwork body, and a partition for partitioning space is installed inside the formwork body. Three sets of mounting slots are symmetrically opened inside the formwork body, and the three sets of mounting slots are the same size. Each set of mounting slots consists of two slots. Mounting strips are slidably connected inside each pair of mounting slots, and a partition is connected to the opposite side of the two mounting strips. A tie rod is installed on the top of the partition.

[0006] Preferably, a limiting block is slidably mounted inside the mounting strip via a reset spring, and a limiting groove is connected to the outside of the limiting block, with the limiting groove being formed inside the mold shell body.

[0007] Preferably, the limiting block and the limiting groove form an engaging structure.

[0008] Preferably, the limiting block is inclined.

[0009] Preferably, a lever is slidably mounted above the partition, and one end of a pull rope is connected to the side of the lever near the mold body, and the other end of the pull rope is connected to a limit block through a guide wheel.

[0010] Preferably, one end of a compression spring is connected to the top of the partition, and the other end of the compression spring is connected to a lever.

[0011] Preferably, a sealing strip is slidably installed inside the mounting groove, and the sealing strip is attached to the inner wall of the mold body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) A partition is provided, and an installation strip is installed on the front and back sides of the partition. Then, an installation groove is slidably connected to the outside of the two installation strips. When it is necessary to adjust the pouring space inside the mold body, the partition can be slidably installed by sliding the installation strip and the installation groove. This allows for adjustment of the pouring space inside the mold body, making it more practical.

[0014] (2) A limiting block is set up. The limiting block is slidably installed inside the mounting strip by a reset spring. When it is necessary to use the partition to adjust the space inside the mold body, the partition can be slidably installed inside the mold body by the mounting strip. At this time, the inclined limiting block will shrink and move by the compression of the mold body. Then the reset spring will automatically spring the limiting block into the limiting groove by its own elasticity. This can fix the position of the partition after installation, and prevent the partition from loosening and separating when the concrete is removed after pouring and molding. The stability is better.

[0015] (3) Furthermore, when it is necessary to install the partition in different positions inside the mold body, simply pull the lever to drive the pull rope through the guide wheel to drive the limit block to retract and move, so that the limit block is separated from the limit groove, and then the partition can be pulled out from the inside of the mold body, so that the space inside the mold body can be adjusted later, making the operation more time-saving and labor-saving.

[0016] (4) Furthermore, by using a compression spring set above the partition plate and a lever connected to the other end of the compression spring, the lever can be elastically reset by the elastic force of the compression spring itself after being pulled, so as to facilitate repeated pulling in the later stage and better assist the concrete in the integral molding effect inside the mold body. This simplifies the operation process, reduces construction costs, and has more obvious advantages compared with traditional molding molds.

[0017] (5) A sealing strip is provided. The sealing strip is slidably installed inside the other installation slots. After the partition is installed inside the mold body, the remaining sealing strips can be slidably installed in the remaining installation slots. This can seal the extra installation slots and prevent concrete from seeping into the interior of the installation slots, which would affect the later space adjustment and better assist the later concrete pouring.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides the following technical solution: a splicing UHPC concrete formwork shell:

[0027] Example 1: To address the problem that existing mold shell bodies 1 cannot adjust the casting space during actual casting production, and can only be used for casting of mold shell bodies 1 of the same size, resulting in poor practicality of the mold shell body 1 and reduced casting efficiency in the later stages, the following is disclosed: Mold shell body 1, wherein the mold shell body 1 has symmetrically opened ventilation holes 2 for venting gas on both sides, and the mold shell body 1 has a partition 3 installed inside for partitioning space. The mold shell body 1 has three sets of mounting slots 5 symmetrically opened inside, and the three sets of mounting slots 5 are the same size. Each set of mounting slots 5 has two slots. The interior of each pair of mounting slots 5 is slidably connected to mounting strips 4, and the opposite sides of the two mounting strips 4 are connected to the partition 3. The top of the partition 3 is equipped with a tie rod 6.

[0028] Inside the mounting strip 4, a limiting block 11 is slidably mounted via a reset spring 12, and the outer side of the limiting block 11 is connected to a limiting groove 13, which is located inside the mold body 1. The limiting block 11 and the limiting groove 13 form a locking structure. The limiting block 11 is inclined. A lever 7 is slidably mounted above the partition 3, and one end of a pull rope 8 is connected to the side of the lever 7 closest to the mold body 1. The other end of the pull rope 8 is connected to the limiting block 11 via a guide wheel. One end of a compression spring 9 is connected to the top of the partition 3, and the other end of the compression spring 9 is connected to the lever 7.

[0029] like Figures 1-4 As shown, when it is necessary to adjust the pouring space inside the mold body 1, the partition 3 can be slidably installed inside the mold body 1 by using the installation strip 4 and the installation groove 5 to slide together. At this time, the inclined limiting block 11 will shrink and move under the pressure of the mold body 1, so that the limiting block 11 shrinks and moves into the limiting groove 13. Then, the return spring 12 will automatically spring the limiting block 11 into the limiting groove 13 by its own elasticity. This can limit and fix the position of the partition 3 after installation, and prevent the partition 3 from loosening and separating when the concrete is removed after pouring and forming. This results in better stability.

[0030] When the installation position of the partition 3 needs to be adjusted, simply pull the lever 7 to drive the pull rope 8 to drive the limit block 11 to retract and move through the guide wheel, so that the limit block 11 separates from the limit groove 13. At this time, the partition 3 can be taken out from the inside of the mold body 1. Then, the partition 3 is installed inside the mold body 1 through different installation grooves 5, so that the pouring space inside the mold body 1 can be freely adjusted. Finally, the position of the lever 7 after pulling can be elastically reset by squeezing the spring 9. The operation is more time-saving and labor-saving.

[0031] Example 2 differs from Example 1 in that it allows for the sealing of the mounting groove 5 of the mold body 1 after spatial adjustment, preventing concrete from seeping into the interior of the mounting groove 5 and affecting subsequent pouring. The following is disclosed:

[0032] A sealing strip 10 is slidably installed inside the mounting groove 5, and the sealing strip 10 is attached to the inner wall of the mold body 1.

[0033] like Figures 1-6 As shown, when the partition plate 3 is installed inside the mold body 1 to adjust its pouring space, the sealing strip 10 is slidably installed in the excess installation groove 5, and the sealing strip 10 is attached to the inner wall of the mold body 1, which can seal the excess installation groove 5, prevent concrete from seeping into the interior of the installation groove 5 and affecting the subsequent space adjustment, and better assist the integral molding effect of concrete inside the mold body 1. This simplifies the operation process, reduces construction costs, and has more obvious advantages compared with traditional molding molds.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] The contents not described in detail in this specification are existing technologies known to those skilled in the art. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
