Description

[Technical Field]

[0001] This invention relates to the field of building construction technology, and in particular to a formwork suitable for unsupported replacement concrete reinforcement and its construction method. [Background Technology]

[0002] The reasonable service life of a building project is generally 50 years. With the rapid development of the construction industry in China since the founding of the People's Republic of my country, a considerable number of buildings have reached their designed service life. In order to effectively extend the service life of buildings, promote energy conservation and emission reduction, and achieve sustainable development, it is necessary to repair and reinforce existing buildings that have reached their designed service life.

[0003] Most existing formwork is not suitable for the construction of local replacement concrete reinforcement method. In addition, the construction of traditional reinforcement formwork often requires a large number of tie bolts to fix the formwork, which will result in too many openings in the formwork, further reducing the service life of the formwork. All of this consumes a lot of reinforcement equipment and does not meet the requirements of green construction and convenient construction.

[0004] Improving resource reuse rates, facilitating construction methods, and reducing construction costs have become new development directions during the construction process.

[0005] Therefore, it is necessary to propose a formwork and its construction method suitable for unsupported replacement concrete reinforcement. [Summary of the Invention]

[0006] This invention provides a template and its construction method suitable for unsupported replacement concrete reinforcement. The construction method is simple, can improve the utilization rate of concrete reinforcement tools, and ensure a good replacement concrete reinforcement effect.

[0007] To achieve the above advantages, the technical solution provided by this invention is as follows:

[0008] This invention provides a template suitable for supportless replacement concrete reinforcement, comprising: a detachable buckle, a buckle connector, and a steel template. The detachable buckle includes a latch, a connector, a latch button, a groove, a fixing component, a threaded hole, a fixing bolt, a dial indicator support rod, and a dial indicator. The latch is located on both sides of the connector and can be retracted by pressing the latch button. The groove is located on the body of the detachable buckle. The fixing component includes a fixing steel bar and a fan-shaped fixing steel plate. The fixing steel bar is inserted into the groove to connect the fixing component to the detachable buckle body. The fan-shaped fixing steel plate is welded to the fixing steel bar for fixing the steel template. The threaded hole connects to the groove, and the fixing bolt is screwed into the threaded hole to secure the fixing steel bar. The dial indicator support rod is used to hold the dial indicator.

[0009] The buckle connector includes a buckle slot and a buckle connection port. The buckle slot is combined with a detachable buckle, and the buckle connection port is locked with the detachable buckle to achieve a tight connection between the detachable buckle and the buckle connector.

[0010] The steel formwork includes connector holes, steel handles, and weak steel plates. The connector holes are opened according to construction requirements, the steel handles are welded to the steel formwork, and the weak steel plates arranged on the steel formwork can be used to easily reflect the solidification state of the concrete using a dial gauge.

[0011] To make the installation steps and construction methods of this invention clearer, this invention preferably provides a technical solution for the construction process, a construction method suitable for supportless replacement concrete reinforcement formwork, which is:

[0012] A. Drill holes for connectors on the steel formwork according to construction requirements;

[0013] B. Assemble the steel template, place the appropriately sized buckle connectors, press the buckle button on the detachable buckle, and combine the detachable buckle with the buckle connectors;

[0014] C. Place the fan-shaped fixing steel plate in the fastener on the surface of the steel template, insert the fixing steel strip into the groove reserved in the detachable buckle, and screw the fixing bolt along the threaded hole to fix the fixing steel strip.

[0015] D. Fix the dial indicator to the dial indicator support rod, so that the dial indicator measuring rod touches the surface of the weak steel sheet;

[0016] E. Repeat the above steps to install the remaining detachable clips according to the number of holes opened in the connectors.

[0017] F. Estimate the reinforcement effect of the replacement concrete by using the dial gauge readings, and complete the construction of the replacement concrete reinforcement formwork.

[0018] This invention provides a formwork suitable for supportless replacement concrete reinforcement, which has the following advantages:

[0019] 1. This invention differs from the traditional method of using tie bolts to fix the template. The prefabricated snap-fit ​​connectors can be precisely embedded inside the reinforced structure, eliminating the tedious construction of removing exposed bolts, improving the efficiency of concrete reinforcement, and reducing costs.

[0020] 2. The detachable clips can be reused after the steel formwork is removed. The embedded clip connectors can be used for the erection of steel formwork in the area adjacent to the replacement concrete reinforcement area, which is convenient for construction and improves the utilization rate of the reinforcement equipment.

[0021] 3. The connection between the fastener and the detachable buckle increases the stress surface of the fastener, which can better avoid damage to the steel formwork and is highly practical.

[0022] 4. The sensitive dial indicator fixed to the detachable buckle can be used to observe the deformation of the weak steel sheet, ensure the reinforcement effect, and further standardize the dismantling time of the template;

[0023] 5. This invention is a prefabricated construction method with a wide range of applications, and can be used for the reinforcement of various reinforced concrete structures. [Attached Image Description]

Detailed Implementation Methods

[0035] To enable those skilled in the art to clearly understand the technical solutions and advantages of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the preferred embodiments described are only some embodiments of the present invention. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. It should be emphasized that, in the absence of conflict, the embodiments and features in the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0036] like Figure 1 As shown, a formwork suitable for supportless replacement concrete reinforcement includes: a detachable snap fastener 1, a snap fastener connector 2, and a steel formwork 3.

[0037] like Figure 2 , Figure 3 As shown, the buckle 11 is located on both sides of the connector plug 12. Pressing the buckle button 13 will cause the buckle 11 to retract and be inserted into the buckle slot 21, and combined with the buckle connection port 22 to realize the connection between the detachable buckle 1 and the buckle connector 2.

[0038] The groove 14 on the abdomen of the detachable buckle 1 is used to connect the fixing steel strip 151 on the fixing member 15. The fixing bolt 17 is screwed into the threaded hole 16 to bind and fix the steel strip 151. At this time, the fan-shaped fixing steel plate 152 fits the steel template 3 to avoid damage to the steel template.

[0039] The dial indicator 19 is placed on the dial indicator support rod 18 to observe the deformation of the weak steel sheet 33 area and determine whether the part reinforced by the replacement concrete has achieved the reinforcement effect of micro-expansion.

[0040] like Figure 4 , Figure 5 As shown, the steel template 3 has multiple pre-drilled holes 31 for connectors and welded steel handles 32. The holes 31 for connectors are opened according to the size of the snap-fit ​​connectors 2. The steel handles 32 ensure the ease of template installation, while the thin steel plates 33 facilitate the dial gauge 19 to reflect the deformation of the newly poured concrete.

[0041] An example of using a formwork suitable for unsupported replacement concrete reinforcement is as follows:

[0042] Step 1: Referring to the construction drawings and considering the arrangement of the reinforcing bars, make connection holes 31 at appropriate positions on the steel formwork 3;

[0043] Step 2: Place the steel template 3 using the steel handle 32, pre-embed the buckle connector 2 of appropriate size, press the buckle button 13 on the detachable buckle 1, the buckle 11 retracts, align the connector plug 12 with the buckle connection port 22, and assemble the detachable buckle 1 and the buckle connector 2.

[0044] Step 3: Connect the fastener 15 to the reserved slide groove 14 of the detachable buckle 1 through the fixing steel strip 151, and screw the fixing bolt 17 into the threaded hole 16 until the fixing bolt 17 can no longer be rotated. At this time, the fixing steel strip 151 is fixed, and the fan-shaped fixing steel plate 152 should fit exactly against the surface of the steel template 3.

[0045] Step 4: Fix dial indicator 19 to dial indicator support rod 18. At this time, the measuring rod of dial indicator 19 is against the surface of the weak steel sheet 33 and has an initial reading. Record this value.

[0046] Step 5: Repeat the above operation, install the remaining detachable clips 1 according to the number of connector holes 31 opened on the steel template 3, and after the arrangement of the detachable clips 1 is completed, pour concrete to complete the construction of the replacement concrete reinforcement template.

[0047] Step 6: Observe the deformation state of the weak steel sheet 33 by changing the reading of the sensitive dial gauge 19, and roughly judge the effect of the replacement concrete reinforcement, and set the dismantling time of the steel formwork 3.

[0048] The technical solution in this embodiment provides a template and its construction method suitable for supportless replacement concrete reinforcement. The detachable clip 1 and clip connector 2 are both prefabricated components, allowing for prefabricated construction of the supportless replacement concrete reinforcement structure in conjunction with the steel template 3. The clip connector 2 can be designed with different embedded dimensions according to different components, meeting various reinforcement needs. Simultaneously, the reusable detachable clip 1 eliminates the cumbersome process of removing exposed bolts required in traditional reinforcement methods. The fixing member 15, equipped with a fan-shaped fixing steel plate 152, effectively prevents damage to the steel template. This invention proposes a template suitable for supportless replacement concrete reinforcement with a wide range of applications, conforming to the concept of green construction. It provides a construction template and method for replacement concrete reinforcement that features low equipment consumption, good reinforcement performance, and convenient construction.
