Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an aluminum template bottom sealing device for concrete pouring in non-standard floor building construction. Background Art

[0002] With the development of the domestic construction market, traditional bamboo and wood formwork for concrete pouring can no longer meet the requirements of rapid construction and energy conservation and environmental protection. Aluminum formwork has been widely promoted and applied because of its high strength, corrosion resistance, anti-aging and other characteristics, as well as its high economy, lightness and flexibility, strong durability, large bearing capacity, high construction efficiency, wide application range and high degree of standardization. However, due to the high degree of standardization of aluminum formwork, the dimensions are all fixed dimensions set according to the floor standards. Therefore, for the construction of non-standard floors, especially the non-standard first floor with a height difference of 50~250mm, if you want to use the finished aluminum formwork for concrete pouring, the height difference at the bottom needs to be supplemented by the bottom formwork. At present, bamboo and wood formwork is used as the bottom formwork for bottom sealing. Due to size restrictions, bamboo and wood formwork often cannot be constructed quickly, and bamboo and wood formwork is not suitable for reinforcement, resulting in serious leakage at the bottom, resulting in poor apparent quality of concrete, and the risk of mold expansion and mold running. Summary of the invention

[0003] The utility model aims to address the defects of the prior art and provide an aluminum formwork bottom sealing device for concrete pouring. The device is used in the construction of non-standard layer buildings and cooperates with the aluminum formwork for bottom sealing to overcome the problem of floor height difference between the non-standard layer and the standard layer when pouring concrete.

[0004] In order to achieve the above purpose, the utility model can adopt the following technical solutions:

[0005] The utility model discloses an aluminum formwork bottom sealing device for concrete pouring, comprising a top plate and a vertical plate, wherein one side edge of the top plate is vertically fixedly connected to the upper edge of the vertical plate to form a bottom sealing formwork with an inverted L-shaped structure; an aluminum formwork connecting hole is arranged on the top plate, and an adjustable plate height extension portion is arranged at the lower portion of the vertical plate on the same side as the top plate, and the adjustable plate height extension portion comprises a pair of L-shaped clamping plates fixedly connected to the left and right edges of the vertical plate, a height adjustment plate that slides up and down in contact with the surface of the vertical plate is clamped between the two L-shaped clamping plates, and positioning bolts for pressing and fixing the height adjustment plates are threadedly penetrated on the two L-shaped clamping plates.

[0006] Furthermore, a plurality of reinforcing support plates with triangular structures are evenly distributed along the length direction at the angle between the top plate and the vertical plate, so as to improve the supporting strength of the top plate and the vertical plate.

[0007] Furthermore, in order to arrange the pull tabs stably during the specific construction process, pull tab connecting ear plates are vertically fixed to the left and right edges of the vertical plate, and the pull tab connecting ear plates are arranged on the same side as the adjustable plate height extension portion.

[0008] Furthermore, positioning grooves matching the positioning bolts are evenly distributed along the height direction on the plate surface of the height adjustment plate, so that the positioning bolts can be fixed in the positioning grooves, thereby enhancing the stability of the positioning bolts pressing the height adjustment plate.

[0009] Furthermore, in order to reduce the leakage of concrete at the lower edge of the height adjustment plate during concrete pouring, a rubber grout blocking strip with a U-shaped cross section is coated on the lower edge of the height adjustment plate.

[0010] Furthermore, the vertical plates can be arranged into two groups, and one side edge of the two groups of vertical plates are vertically fixedly connected. At this time, the top plate is an L-shaped plate connected to the upper edge of the inner corner side or the upper edge of the outer corner side of the two vertical plates, thereby enhancing the diversity of use and adapting to different shapes surrounded by aluminum formwork for concrete pouring.

[0011] The utility model has the advantages that the inverted L-shaped structure formed by the top plate and the vertical plate can be stably connected to the bottom edge of the aluminum template for concrete pouring to form a bottom seal, and the adjustable plate height extension part at the lower part of the vertical plate can be used to change the height of the vertical plate, so as to adapt to the bottom seal of the aluminum template for concrete pouring of different heights; the entire bottom seal device can be easily used in conjunction with the aluminum template, and can be prefabricated in the factory, which is convenient for rapid installation and height adjustment at the construction site, improves adaptability, reduces construction difficulty, reduces leakage of slurry at the bottom of the aluminum template for concrete pouring, ensures the apparent quality of concrete, and reduces the risk of mold expansion and mold running at the bottom seal of the aluminum template for concrete pouring.

[0014] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] like Figure 1As shown, the aluminum template bottom sealing device for concrete pouring described in the utility model comprises a top plate 1 and a vertical plate 2; wherein, one side edge of the top plate 1 is vertically fixedly connected to the upper edge of the vertical plate 2 to form a bottom sealing template of an inverted L-shaped structure. Of course, the top plate 1 and the vertical plate 2 can also be an integral structure, both of which are aluminum plates with a thickness of 3 mm. The width of the top plate 1 is generally 50 mm, 100 mm or 150 mm. When the width of the top plate 1 is 50 mm, the height of the vertical plate 2 is 100 mm. When the width of the top plate 1 is 100 mm, the height of the vertical plate 2 is 150 mm. When the width of the top plate 1 is 150 mm, the height of the vertical plate 2 is 200 mm. That is, the bottom sealing template composed of the top plate 1 and the vertical plate 2 has three models: 50×100×3 mm, 100×150×3 mm, and 150×200×3 mm. In addition, in order to improve the supporting strength of the bottom cover template composed of the top plate 1 and the vertical plate 2, a plurality of reinforcing support plates 3 with triangular structures may be evenly distributed along the length direction at the angle between the top plate 1 and the vertical plate 2.

[0016] Aluminum formwork connection holes 4 are provided on the top plate 1. Specifically, a plurality of aluminum formwork connection holes 4 are evenly spaced along the length direction of the top plate 1, and their opening positions should be matched one by one with the bolt connection holes on the bottom edge of the aluminum formwork for concrete pouring to be connected above the top plate 1, so as to facilitate the top plate 1 and the aluminum formwork for concrete pouring to be quickly fixed together by pins or connection bolts.

[0017] An adjustable plate height extension portion is provided at the lower part of the vertical plate 2 on the same side as the top plate 1. Specifically, the adjustable plate height extension portion includes a pair of L-shaped clamping plates 5 fixedly connected to the left and right edges of the vertical plate 2, a height adjustment plate 6 sliding up and down in contact with the plate surface of the vertical plate 2 is clamped between the two L-shaped clamping plates 5, and positioning bolts 7 for pressing and fixing the height adjustment plate 6 are screwed through the two L-shaped clamping plates 5; wherein, the outer edges of the short plate sections of the two L-shaped clamping plates 5 are fixedly connected to the plate surface of the vertical plate 2, and the two L-shaped clamping plates 5 are symmetrically and oppositely arranged, and the inner sides thereof just form a pair of clamping cavities that can clamp the left and right edges of the height adjustment plate 6; at this time, the positioning bolt 7 is vertically screwed and penetrated on the long plate section of the L-shaped clamping plate 5 from the outside to the inside, so that when the positioning bolt 7 is screwed inward, the inner end of the positioning bolt 7 can pass through the L-shaped clamping plate 5 and press on the plate surface of the height adjustment plate 6, so that the height adjustment plate 6 is fixed. In addition, in order to enhance the stability of the top pressure fixation of the height adjustment plate 6, two groups of positioning bolts 7 can be vertically spaced on the long plate section of each L-shaped pallet 5, and a plurality of positioning grooves 8 used in conjunction with the positioning bolts 7 are evenly distributed along the height direction on the plate surface of the height adjustment plate 6. The center distance between two adjacent positioning grooves 8 should be consistent with the axial distance between the two groups of positioning bolts 7 on the same L-shaped pallet 5, or the center distance between two adjacent positioning grooves 8 is half of the axial distance between the two groups of positioning bolts 7 on the same L-shaped pallet 5.

[0018] When carrying out the bottom sealing construction of the aluminum formwork for concrete pouring, a bottom sealing formwork is correspondingly arranged below the aluminum formwork for concrete pouring according to the specific shape thereof (generally a rectangular shape), so that the top plate 1 of the bottom sealing formwork is fitted and fixedly connected with the bottom edge of the aluminum formwork for concrete pouring, so that the vertical plate 2 of the bottom sealing formwork is correspondingly erected below the aluminum formwork for concrete pouring, and ensure that the adjustable plate height extension part of the lower part of the vertical plate 2 is located on the outer side of the aluminum formwork for concrete pouring; thereafter, the height of the height adjustment plate 6 can be adjusted according to the specific height of the bottom sealing position below the aluminum formwork for concrete pouring, so that the lower edge of the height adjustment plate 6 is attached to the ground, thereby forming a bottom sealing enclosed at the bottom of the aluminum formwork for concrete pouring, and the gap between the height adjustment plates 6 on two adjacent vertical plates 2 can be sealed by patch welding or external rubber strips. In addition, in order to avoid the gap between the lower edge of the height adjustment plate 6 and the ground as much as possible, a rubber plugging strip 9 with a U-shaped cross section can be coated on the lower edge of the height adjustment plate 6. The rubber plugging strip 9 has a certain flexibility, which can make the lower edge of the height adjustment plate 6 fit more closely with the ground, and effectively reduce the slurry from the lower edge of the height adjustment plate 6 during concrete pouring. Further, in order to be able to use a pull tab (a pull tab is a common inner and outer membrane pulling tool for aluminum membrane panels on the market) to pull and fix the two relatively arranged vertical plates 2 during the specific construction process, a pull tab connecting ear plate 10 for connecting the pull tab can also be vertically fixed at the left and right edges of the vertical plate 2. The pull tab connecting ear plate 10 is set on the same side as the adjustable plate height extension part. During construction, a pull tab can be connected between the pull tab connecting ear plates 10 on the two relatively arranged vertical plates 2, so that the pull tab can be transversely passed and embedded in the poured concrete component, thereby improving the overall rigidity.

[0019] In addition, in order to enhance the diversity of use, it is suitable for different shapes surrounded by aluminum formwork for concrete pouring, such as Figure 2 , 3 As shown, the vertical boards 2 can also be arranged into two groups, and one side edge of the two groups of vertical boards 2 are vertically fixedly connected to form a right-angle corner structure; at this time, the top plate 1 is a horizontal plate member with an overall L-shaped structure, which is correspondingly connected to the upper edge of the inner corner side or the upper edge of the outer corner side of the two vertical boards 2, and the adjustable board height extension parts are two groups respectively arranged on the two vertical boards 2, or the height adjustment plates 6 of the two groups of adjustable board height extension parts are connected as a whole to form an integrated L-shaped adjustment plate that fits on the board surfaces of the two vertical boards 2.

[0020] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
