Description

Technical Field

[0001] The invention relates to the technical field of building formwork, and in particular to a building aluminum alloy formwork with a water vapor discharge function and a construction method. Background Art

[0002] Aluminum alloy formwork for construction is made of high-quality aluminum plates and aluminum alloy materials. It is a professional construction formwork suitable for concrete engineering. Aluminum formwork is used as temporary support and protection when pouring concrete. It is made according to design requirements to shape concrete structures or components according to specified positions and geometric dimensions, maintain its correct position and bear the deadweight of the construction formwork and external loads acting on it. It is an indispensable part of modern construction projects; aluminum alloy formwork is a new generation of formwork type after wooden formwork and steel formwork. It has the characteristics of short construction period, many times of reuse, convenient construction, high efficiency, good stability and high bearing capacity. It is currently widely used in construction. It also has high toughness and corrosion resistance, can adapt to various environments, and can effectively reduce unnecessary losses when using the formwork.

[0003] When the aluminum formwork is used, the aluminum formwork components are installed and assembled, and then concrete is poured in the space between the aluminum formworks to ensure the perfect forming of the concrete. Usually, when the concrete is poured between the aluminum formworks, it is also necessary to vibrate and stir the concrete to help the concrete to form. However, in the current construction projects, the use of aluminum alloy formworks mainly has the following problems: First, when the concrete is poured, there will be gas that has not been discharged in time between the aluminum formworks. Although some of the gas will be discharged through vibration and stirring, there will still be a large amount of gas that cannot be discharged. These gases will produce a large number of pores on the surface of the concrete as the concrete solidifies and forms. The existence of these pores seriously affects the forming effect of the building body, and will also increase the later construction cost. At the same time, it will also reduce the safety performance of the building body and pose a safety hazard; second, the concrete will produce a high degree of water thermalization during the solidification process, which will cause a large temperature difference in the concrete structure. The water in it needs to evaporate gradually as the concrete solidifies, so that cavities will be formed. Finally, after the concrete is formed, it will produce pitting, pitting, cavities, etc. that affect the appearance and quality of the building body.

[0004] In the prior art, an aluminum formwork with air permeable pores is disclosed, and the Chinese patent number is CN218758690U, which includes two aluminum formwork bodies and a fixing device connecting the two aluminum formwork bodies. The surfaces of the two aluminum formwork bodies are respectively provided with air permeable devices, including positioning columns and a plurality of exhaust holes. The plurality of exhaust holes are evenly distributed circumferentially on the outside of the positioning columns. The device solves the problem of a large number of air holes generated by bubbles in concrete under the aluminum formwork support as the concrete is formed.

[0005] However, the above disclosed prior art still has the following defects in use: (1) The exhaust holes on the aluminum formwork will cause a small amount of concrete to flow out of the exhaust holes to the adjustment holes during the concrete pouring or vibration process, and will cause blockage of the exhaust holes and the adjustment holes, reducing the utilization rate of the concrete and the exhaust effect during the pouring and solidification process; (2) It is impossible to discharge the large amount of high-pressure gas generated during the vibration process in a timely manner, and it is also impossible to clean the exhaust holes efficiently, resulting in a large amount of cleaning work and reducing construction efficiency. Summary of the invention

[0006] In view of the defects existing in the above-mentioned prior art, the purpose of the present invention is to propose an aluminum alloy formwork for construction with a water vapor discharge function and a construction method, by arranging a multi-layer water vapor discharge mechanism at the connection between the first formwork and the second formwork, the moisture and gas in the concrete can be discharged without losing the concrete, and through the mutual cooperation between the pressure relief part and the water vapor discharge mechanism, a large amount of moisture and gas in the process of concrete pouring and vibration can be quickly released to solve the problems existing in the background technology.

[0007] In order to achieve the above object, the present invention adopts the following technical solution: In a first aspect, the present invention provides an aluminum alloy template for construction with a water vapor discharge function, comprising a first template and a second template connected to each other, a water vapor discharge mechanism is arranged between the first template and the second template, and the water vapor discharge mechanism comprises: A primary filtering part is arranged on the second template; The fine filter part is embedded in the first template. When the first template is connected to the second template, the fine filter part contacts the primary filter part, and concrete impurities are filtered out through the primary filter part and the fine filter part. The pressure relief part is arranged on the second template. When the first template is connected with the second template, the pressure relief part cooperates with the fine filter part to discharge the high-pressure water vapor in the fine filter part in an emergency through the pressure relief part.

[0008] According to a further preferred embodiment of the above technical solution, the fine filter parts include a plurality of fine filter parts, which are evenly arranged on the first template, and a plurality of fixing frames for installing the fine filter parts are correspondingly arranged on the first template, and each fine filter part includes: A first filter element is installed in the fixing frame and close to a side of the second template; The second filter element is installed in the fixing frame and at a side away from the second template, and a gap is reserved between the first filter element and the second filter element; The cleaning and wiping component is movably arranged in the gap, and two sides of the cleaning and wiping component are respectively in contact with the first filter element and the second filter element.

[0009] Based on the above technical solution, further, a limiting groove matching the first filter element is provided on the fixing frame, and the first filter element is located in the limiting groove.

[0010] A further preferred solution is that the fixing frame is connected to the first template via a fastener.

[0011] As a further preferred embodiment of the above technical solution, the cleaning assembly includes a cleaning strip, a supporting block and a first spring. The cleaning strip is connected to the top of the supporting block and movably arranged in the gap. The supporting block is located below the fixed frame. The first spring includes a plurality of strips and one end of the first spring is connected to the bottom of the supporting block. The other end of the first spring is connected to the first template.

[0012] A further preferred solution is: the pressure relief parts include multiple ones, and each pressure relief part is arranged corresponding to each fine filter part, and each pressure relief part includes: A pressure relief seat, which is fixedly connected to the second template; The pressure relief component is arranged at the upper end of the vent hole inside the pressure relief seat.

[0013] A further preferred solution is: the pressure relief assembly includes a first wedge block, a second wedge block and a second spring, the second wedge block is connected to the exhaust port, the first wedge block is connected to the bottom of the second wedge block through the second spring, and the first wedge block is movably matched with the vent.

[0014] Furthermore, when the first template is connected to the second template, the bottom of the pressure relief seat abuts against the cleaning assembly, and under the action of the pressure relief seat, the cleaning assembly moves downward to form a cavity between the first filter element and the second filter element.

[0015] In a second aspect, the present invention provides a construction method of an aluminum alloy formwork for construction with a water vapor discharge function, comprising the following steps: Step 1: Arrange the aluminum alloy formwork according to the engineering design requirements, and connect the aluminum alloy formworks that are close to each other in sequence; Step 2: Concrete is poured in the space formed by the aluminum alloy template. The large particles of slag in the concrete are isolated by the primary filter. The small particles of mud, water, and gas in the concrete enter multiple fine filter parts after passing through the primary filter. Most of the small particles of mud are filtered out by the first filter. The tiny particles, water, and gas in the small particles of mud enter the second filter. After being filtered out again by the second filter, the water and gas are discharged from the joint between the first template and the second template. Step 3: When a large amount of water and gas accumulate in the fine filter, high-pressure water vapor will be formed in the cache space here. The high-pressure water vapor enters the vent hole, pushing the first wedge block to move upward to open the exhaust port, and the high-pressure gas is quickly released through the exhaust port.

[0016] Compared with the prior art, the technical solution of the present invention has the following beneficial effects: 1. The present invention designs a water vapor discharge mechanism with a multi-layer filter structure between two adjacent aluminum alloy templates, which can timely and efficiently discharge the gas and excess water in the concrete pouring and vibration process while ensuring that the concrete is not lost, thereby avoiding the appearance of holes, rough surfaces and other defects on the surface of the concrete after solidification. These defects not only affect the appearance, but also affect the safety performance of the building; using the water vapor discharge mechanism, the water in the concrete can be discharged in time, which can effectively shorten the solidification time of the concrete structure, help to shorten the construction period, and improve the construction quality at the same time.

[0017] 2. The water vapor discharge mechanism of the present invention comprises a primary filter part and a fine filter part. The primary filter part adopts a single-layer filter mesh structure, and the fine filter part adopts a double-layer filter mesh structure. During the pouring and vibrating process of concrete, large particles of slag and stone in the concrete will first be removed through the filter mesh of the primary filter part, while small particles of mud will pass through the filter mesh of the primary filter part and then be diverted to multiple fine filter parts. Small particles of mud in other positions will be retained in the gap between the first template and the second template. Water and gas reach the first filter element through the gap, and the small particles of mud entering are further filtered out by the first filter element. The tiny particles reach the second filter element after passing through the first filter element, and the tiny particles are filtered out after passing through the second filter element. After passing through the second filter element, the water and gas are discharged from the joint at the joint of the first template and the second template after passing through the second filter element, thereby effectively improving the forming effect of the concrete.

[0018] 3. The pressure relief part of the present invention is arranged on the second template. When the first template and the second template are installed, the pressure relief part and the fine filter part cooperate with each other. Specifically, the pressure relief seat squeezes the cleaning strip and moves downward to form a buffer space between the first filter element and the second filter element. Water and gas gather in this buffer space to generate high pressure. High-pressure water vapor enters from the air inlet at the lower end of the vent, pushing the first wedge-shaped block to move in the direction of the second wedge-shaped block, so that the exhaust port at the upper end of the vent is no longer blocked, and the high-pressure water vapor is discharged from this exhaust port, which effectively improves the discharge efficiency of the high-pressure water vapor and avoids damage to the first filter element and the second filter element due to the accumulation of high-pressure water vapor.

[0019] 4. The pressure relief part provided in the present invention has the function of emergency discharge of water vapor. By designing the exhaust port at the upper end of the pressure relief seat into a trapezoidal structure, when the air pressure in the buffer space is relatively low, the water vapor is not discharged through the pressure relief part. When more water vapor gathers in the buffer space to form high pressure, the high-pressure water vapor at this time enters the vent hole in the pressure relief seat, and the high-pressure gas forms an upward thrust on the first wedge block, so that the first wedge block no longer blocks the vent hole, and the high-pressure water vapor will be temporarily and quickly discharged from here.

[0020] 5. The filter surfaces of the primary filter part and the fine filter part of the present invention are easy to clean. The contact surface between the primary filter part and the first filter element is cleaned by the mutual sliding friction between the first template and the second template during installation. If there is a lot of mud and lime adhesion, manual cleaning and maintenance are performed. The close surfaces of the first filter element and the second filter element are cleaned by a cleaning strip. Specifically, through the cooperation of the cleaning strip and the pressure relief seat, when the first template is connected to the second template, the pressure relief seat squeezes the cleaning strip downward to compress the first spring. When the first template and the second template are removed, the cleaning strip is pushed upward during the elastic resetting process of the first spring, and the first filter element and the second filter element are automatically cleaned through the two sides of the cleaning strip.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0025] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc., are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0026] In the present invention, only one group of aluminum alloy formworks that cooperate with each other is displayed to illustrate the process of clearing bubbles and excess moisture in concrete by the aluminum alloy formworks when actually used. The purpose is to effectively improve the overall molding effect and safety after concrete pouring. In an actual construction site, multiple groups of aluminum alloy formworks designed by the present invention need to be assembled. During assembly, the existing technology is combined, the structural edge line is determined according to the designed engineering drawing, and the aluminum alloy formwork is installed according to the structural edge line. Before assembling the formwork, the positioning steel bars are welded first (to ensure the turnover number of the aluminum alloy formworks, the formworks need to be coated with stripping paint in advance before use), and then the aluminum alloy formworks of the present invention are assembled on both sides of the positioning steel bars by pins, pins, etc. After the assembly is complete, concrete pouring, vibration and other subsequent construction are carried out according to conventional operating steps. Embodiment 1:

[0027] Reference Figure 1-9The present invention proposes an aluminum alloy template for construction with a water vapor discharge function. Taking a group of mutually connected and matched aluminum alloy templates as an example, the template includes a first template 1 and a second template 2. The assembly sides of the first template 1 and the second template 2 are matched and fixed to each other. A water vapor discharge mechanism 3 is arranged between the first template 1 and the second template 2. The water vapor discharge mechanism 3 includes a primary filter part 31, a fine filter part 32 and a pressure relief part 33. The primary filter part 31 is arranged on the second template 2 to initially isolate large particles of slag in the concrete. A plurality of mounting grooves 11 are evenly arranged on the first template 1 along the length direction. The mounting grooves 11 are used to embed the fine filter part 32. When the first template 1 and the second template 2 are connected, the water vapor discharge mechanism 3 is arranged between the first template 1 and the second template 2. When connected, the fine filter part 32 is in contact with the primary filter part 31, and the fine filter part 32 filters out small particles of mud in the concrete after passing through the primary filter part. After two layers of filtration by the primary filter part 31 and the fine filter part 32, only moisture and gas in the concrete pouring, vibration process and solidification stage are left. The pressure relief part 33 is arranged on the second template 2. When the first template 1 is connected to the second template 2, the pressure relief part 33 cooperates with the fine filter part 32. When moisture and gas accumulate in large quantities, high pressure is formed in the space where the fine filter part 32 is located. At this time, it is necessary to discharge the high-pressure water gas in the fine filter part 32 through the pressure relief part 33 to avoid damage to the structure of the fine filter part 32.

[0028] Specifically, the first template 1 and the second template 2 are based on the conventional aluminum alloy membrane plate in the prior art, and an improved design is made at the joint of each template, wherein: the sides of the first template 1 and the second template 2 that are close to each other are respectively processed into an "L" shape and an inverted "L" shape with matching sizes, and a number of first threaded holes and corresponding second threaded holes are respectively opened along the length direction at the "L" shape and the inverted "L" shape. After the first template 1 and the second template 2 are overlapped through the "L" shape and the inverted "L" shape, each first threaded hole is aligned with the second threaded hole, and bolts are inserted into the first threaded hole and the second threaded hole in sequence, so that the first template 1 and the second template 2 are detachably connected. After the first template 1 and the second template 2 are connected, a seam will be left at their joint.

[0029] like Figure 3 As shown, the primary filter part 31 is installed on the side of the second template 2 close to the first template 1. The primary filter part 31 is the same length as the second template 2 and is made of a concrete slurry filter screen commonly used in construction. A slot is opened on the second template 2, and the primary filter part 31 is embedded in the slot. After being used for a period of time, the primary filter part 31 can be disassembled and replaced to ensure the filtering effect of the primary filter part 31.

[0030] After the concrete is filtered by the primary filter, the large particles of slag in the concrete will be isolated and screened out, but a part of the small particles of mud will still pass through the primary filter 31 and enter the joint. Considering this, the present invention sets a fine filter 32 on the first template 1, the purpose of which is to filter out this part of the small particles of mud again, as follows: like Figure 5-7 As shown, the fine filter part 32 includes a plurality of fine filter parts. In this embodiment, a total of four fine filter parts 32 are provided and are evenly arranged on the first template 1. A fixing frame 4 is respectively installed at each mounting groove 11 of the first template 1. The fixing frame 4 is detachably connected to the first template 1 through a fastener, wherein: Each fine filter part 32 includes a first filter element 321, a second filter element 322 and a cleaning assembly 323. The first filter element 321 is installed in the fixing frame 4 and is close to the side of the second template 2, and a limiting groove matching the first filter element 321 is provided on the fixing frame 4. The first filter element 321 is installed in the limiting groove, and the second filter element 322 is installed in the fixing frame 4 and is away from the side of the second template 2. After the first filter element 321 and the second filter element 322 are installed in place, a gap is reserved between the first filter element 321 and the second filter element 322. The cleaning assembly 323 is movably arranged in the gap, and the two sides of the cleaning assembly 323 are respectively abutted against the first filter element 321 and the second filter element 322. When the cleaning assembly 323 moves up and down to be displaced, the cleaning assembly 323 can clean the impurities filtered out by the first filter element 321 and the second filter element 322.

[0031] Furthermore, if Figure 8-9 As shown, the cleaning assembly 323 includes a cleaning strip 3231, a supporting block 3232 and a first spring 3233. The cleaning strip 3231 is fixedly connected to the top of the supporting block 3232, and the cleaning strip 3231 is movably inserted into the gap. The supporting block 3232 is located in the mounting groove and is arranged below the fixing frame 4. The length of the supporting block 3232 is greater than the length of the cleaning strip 3231. When the cleaning strip 3231 is displaced upward, the supporting block 3232 limits the moving distance of the cleaning strip 3231. The first spring 3231 includes a plurality of first springs, one end of the first spring 3231 is fixedly connected to the bottom of the supporting block 3232, and the other end of the first spring 3231 is fixedly connected to the first template 1.

[0032] During construction, after all the templates are spliced ​​together according to the design requirements, concrete is poured into the space formed by the splicing of the templates. Taking this embodiment as an example, at the joint of the first template 1 and the second template 2, the large particles of slag in the concrete are preliminarily screened out through the primary filter part 31, and the smaller particles of mud, moisture, and gas will enter between the first template 1 and the second template 2 through the primary filter part 31. The small particles of mud are filtered out for the second time from the primary filter part 31 to the first filter element 321. After passing through the first filter element 321, most of the small particles of mud are filtered out, and a small part of the tiny particles, moisture, and gas enter the gap after passing through the first filter element 321, and are finally filtered through the second filter element 322. After passing through the second filter element 322, the tiny particles are completely filtered out, and the moisture and gas are discharged from the outer gap at the joint of the first template 1 and the second template 2 after passing through the second filter element 322.

[0033] In the present invention, the primary filter 31, the first filter element 321 and the second filter element 322 are respectively made of concrete slurry filter screens with different filter densities, and through multi-stage filtration, the loss of concrete is reduced while the moisture and gas in the concrete are finally discharged. Embodiment 2:

[0034] On the basis of the above-mentioned embodiment 1, considering that a large amount of moisture and gas will enter between the first template 1 and the second template 2 during the concrete vibration process, high pressure will be formed in the buffer space of the fine filter part 32. If it cannot be discharged in time, the first filter element 321 and the second filter element 322 may be damaged. Therefore, the specific structure of the pressure relief part 33 is further designed as follows.

[0035] like Figure 10-15 As shown, a plurality of pressure relief parts 33 are provided, each pressure relief part 33 is correspondingly provided in each fine filter part 32 and the two cooperate with each other, each pressure relief part 33 includes a pressure relief seat 331 and a pressure relief assembly 332, the pressure relief seat 331 is fixedly connected to the second template 2 and extends downward, and a vent 3311 is provided inside the pressure relief seat 331, and the vent 3311 is a special-shaped structure composed of a rectangular and a trapezoidal cross-section. In the present embodiment, the junction of the rectangle and the trapezoid is defined as a transfer interface, and the lower end and the upper end of the pressure relief seat 331 are respectively provided with an air inlet and an exhaust port, and the pressure relief assembly 332 is located at one end of the exhaust port of the pressure relief seat 331, and the pressure relief assembly 332 cooperates with the vent 3311.

[0036] Specifically, refer to Fig.11 , Fig.15The pressure relief assembly 332 includes a first wedge block 3321, a second wedge block 3322 and a second spring 3323. The second wedge block 3322 is detachably connected to the exhaust port. The second wedge block 3322 is connected to the pressure relief seat 331 through a snap-fit ​​structure. The second wedge block 3322 remains static at the vent 3311. The first wedge block 3321 is connected to the bottom of the second wedge block 3322 through the second spring 3323, and the first wedge block 3321 is movably matched with the vent 3311. When the pressure is not relieved, the first wedge block 3321 is blocked at the adapter. In the pressure relief state, the high-pressure gas pushes the first wedge block 3321 upward to compress the second spring 3323. At this time, the first wedge block 3321 is no longer blocked at the adapter, and the gas is discharged from the vent 3311 from bottom to top.

[0037] Furthermore, if Fig.12 As shown, when the first template 1 and the second template 2 are connected, the bottom of the pressure relief seat 331 abuts against the cleaning strip 3231, and the cleaning strip 323 is pressed downward by the pressure relief seat 331 to form a cavity between the first filter element 321 and the second filter element 322; the contacting side of the first filter element 321 and the primary filter portion 31 is cleaned by the sliding cooperation of the first template 1 and the second template 2 during installation. If it is found that there is a lot of mud and ash, manual cleaning and maintenance can be carried out regularly. The close side of the first filter element 321 and the second filter element 322 is cleaned by the cleaning strip 3231. When the first template 1 and the second template 2 are installed, the cleaning strip 3231 is pressed downward by the pressure relief seat 331 to form a buffer space between the first filter element 321 and the second filter element 322. When the cleaning strip 3231 moves downward, the second spring 3323 is compressed synchronously. When the first template 1 and the second template 2 are removed, the pressure relief seat 331 no longer presses the cleaning strip 3231. Fig.13 As shown, the cleaning strip 3231 automatically cleans and wipes away impurities on the mutually adjacent sides of the first filter element 321 and the second filter element 322 under the elastic force recovery action of the second spring 3323 . Embodiment three:

[0038] The present invention provides a construction method for an aluminum alloy formwork for construction with a water vapor discharge function. The use state of the first formwork 1 and the second formwork 2 during concrete pouring is as follows: Fig.16 As shown ( Fig.16 Only a set of first template 1 and second template 2 is taken as an example), the details are as follows: First, the structural edge is determined according to the designed engineering drawing, and the aluminum alloy formwork is installed according to the structural edge (the operation of the aluminum alloy formwork before installation adopts the existing conventional technology in this field, such as applying stripping paint to the formwork, welding positioning steel bars, inserting tension screws, etc.); When installing the aluminum alloy template, after the first template 1 and the second template 2 are overlapped, each first threaded hole is aligned with the second threaded hole, and bolts are inserted into the first threaded hole and the second threaded hole in sequence to connect the first template 1 and the second template 2. After the first template 1 and the second template 2 are connected, a seam will be left at the joint; follow this step to install all aluminum alloy templates in sequence; Then, concrete is poured in the space formed by the aluminum alloy formwork, and vibrated synchronously during the pouring process. In this process, large particles of slag in the concrete will be isolated by the primary filter, while small particles of mud, moisture, and gas in the concrete will enter the joint between the first formwork 1 and the second formwork 2 after passing through the primary filter. The primary filter 31 is in contact with the first filter element 321. After the small particles of mud, moisture, and gas enter the first filter element 321, the small particles of mud are filtered again, and only tiny particles, moisture, and gas pass through the first filter element 321 and enter the second filter element 322. The tiny particles are filtered out by the second filter element 322, and the moisture and gas are finally discharged through the joint between the first formwork 1 and the second formwork 2. When a large amount of moisture and gas accumulate in the buffer space between the first filter element 321 and the second filter element 322, high-pressure water vapor will be formed in the buffer space, and the high-pressure water vapor will enter the pressure relief seat 331 through the air vent 3311, and push the first wedge block 3321 that is blocked at one end of the exhaust port of the air vent 3311, so that the first wedge block 3321 presses the second spring 3323 to move toward the direction of the second wedge block 3322. At this time, the exhaust port at the upper end of the air vent 3311 is opened, and the high-pressure water vapor will be quickly discharged through the exhaust port, thereby effectively improving the discharge efficiency of the high-pressure water vapor, so as to prevent the high-pressure water vapor from accumulating for a long time and causing damage to the filtering structures such as the first filter element 321 and the second filter element 322.
