Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a prefabricated composite slab and floor slab integral casting anti-leakage top corner mold. Background Technology

[0002] With the continuous advancement of industrialization in construction, prefabricated concrete structures have been widely used in modern construction projects due to their advantages such as high construction efficiency, controllable quality, energy saving, and environmental protection. Among them, prefabricated composite slabs, as an important component of the floor slab system, are usually prefabricated in the factory and transported to the site for hoisting. They are then integrated with the surrounding cast-in-place structures (such as beams and walls) to form an integral load-bearing floor system. However, the doorway beam structure uses aluminum formwork for installation. Due to factors such as the leveling of the aluminum alloy formwork and the decrease in stiffness over time, after the concrete is poured at the joint between the prefabricated composite slab and the aluminum alloy formwork of the lower beam, grout leakage and slag inclusion are prone to occur at the joint. This requires personnel to chisel and repair, wasting labor and increasing project costs. Utility Model Content

[0003] The technical problem to be solved by this utility model embodiment is to provide a prefabricated composite slab and floor slab integral casting anti-leakage top corner mold. By setting the anti-leakage component, a barrier can be formed between the composite slab and the aluminum mold body to prevent grout leakage.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated composite slab and floor slab integrally cast anti-leakage top corner mold, comprising:

[0005] An aluminum mold body, wherein a stacking plate is provided on the top of the aluminum mold body and a bonding plate is provided on one side of the aluminum mold body;

[0006] A grout-proof component is provided between the aluminum formwork body and the composite plate to prevent concrete grout from flowing out of the gap. The grout-proof component includes: a groove, an iron slot, a hollow rubber strip, a sealing groove, and a sealing rubber strip. The top of the aluminum formwork body has a groove, the groove has an iron slot, and the iron slot has a hollow rubber strip. Both sides of the composite plate have sealing grooves, and the sealing grooves have sealing rubber strips inside.

[0007] Furthermore, the aluminum mold body is C-shaped, with side plates connected to both sides of the aluminum mold body. The side plates have multiple fastening holes for connecting with aluminum mold pins. The bonding plate is U-shaped, with both sides of the bonding plate tightly attached to one side of the side plate. The bonding plate has multiple connecting holes, and the positions of the multiple connecting holes correspond to the fastening holes.

[0008] Furthermore, the metal slot is U-shaped, and two symmetrically arranged protrusions are connected to the inner side of the metal slot.

[0009] Furthermore, the hollow rubber strip is an O-shaped sealing hollow rubber strip, and the sealing strip is a D-shaped hollow sealing strip.

[0010] Furthermore, the sealing groove corresponds to the groove, and the top of the bonding plate has two notches that communicate with the sealing groove, and the bottom wall of the notch is flush with the bottom wall of the iron card groove.

[0011] Furthermore, the length of the iron slot is adapted to the length of the groove, the length of the hollow adhesive strip is greater than the length of the iron slot, and both ends of the hollow adhesive strip extend into the notch, and the top of the sealing adhesive strip contacts the bottom surface of the hollow adhesive strip.

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

[0013] By setting an iron slot with a hollow rubber strip on the top of the aluminum formwork body, and cooperating with the sealing groove and sealing strip on the bonding plate, a sealing structure is formed. After the bonding plate is installed, it is deformed under pressure and automatically fills the tiny gaps between the aluminum formwork body and the bonding plate, forming a continuous sealing barrier, which effectively prevents concrete slurry leakage. Moreover, the two ends of the hollow rubber strip extend to the gap of the bonding plate and are in close contact with the sealing strip, forming a closed leak-proof system and blocking the path of slurry overflow.

[0014] Secondly, the U-shaped structure of the metal slot, combined with the convex strip design, ensures that the hollow rubber strip is securely engaged, preventing displacement or detachment during use. Furthermore, the notch width of the bonding plate is smaller than the width of the metal slot, further limiting the displacement of the metal slot and ensuring that the sealing assembly is always in the optimal working position.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] This application provides a prefabricated composite slab and floor slab integral casting anti-leakage corner mold, which solves the grout leakage problem between the existing composite slab and aluminum formwork body.

[0026] By setting an iron slot 201 with a hollow rubber strip 203 on the top of the aluminum mold body 1, and cooperating with the sealing groove 401 and sealing rubber strip 402 on the bonding plate 4, a sealing structure is formed. After the composite plate 3 is installed, it is deformed under pressure and automatically fills the tiny gaps between the aluminum mold body 1 and the composite plate 3, forming a continuous sealing barrier to effectively prevent concrete slurry leakage. The hollow rubber strip 203 extends to the notch 403 of the bonding plate 4 at both ends and is in close contact with the sealing rubber strip 402 to form a closed leak-proof system, blocking the overflow path of the slurry. The iron slot 201 adopts a U-shaped structure with a protruding strip 202 design to make the hollow rubber strip 203 securely engaged, preventing displacement or detachment during use. The width of the notch 403 of the bonding plate 4 is smaller than the width of the iron slot 201, further limiting the displacement of the iron slot 201 and ensuring that the sealing structure is always in the optimal working position.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] Reference Figure 1 , Figure 2 and Figure 4As shown, the prefabricated composite slab and floor slab integral casting anti-leakage top corner mold includes: an aluminum mold body 1, a composite slab 3 on the top of the aluminum mold body 1, and a bonding plate 4 on one side of the aluminum mold body 1; an anti-leakage component disposed between the aluminum mold body 1 and the composite slab 3 to prevent concrete slurry from flowing out from the gaps. The anti-leakage component includes: a groove 2, an iron slot 201, a hollow rubber strip 203, a sealing groove 401, and a sealing strip 402. The aluminum mold body 1 has a groove 2 on the top, an iron slot 201 inside the groove 2, and a hollow rubber strip 203 inside the iron slot 201. Both sides of the bonding plate 4 have sealing grooves 401, and the sealing grooves 401 have sealing strips 402 inside. The hollow rubber strip 203 is an O-shaped sealing hollow rubber strip, and the sealing strip 402 is a D-shaped hollow sealing strip.

[0029] In use, the aluminum mold body 1 is installed on the top of the wall panel using aluminum mold pins. Then, the iron slot 201 with hollow rubber strip 203 is inserted into the groove 2, and the size of the iron slot 201 is adapted to the groove 2. Next, the bonding plate 4 is placed on one side of the aluminum mold body 1, and the connecting hole 404 on the bonding plate 4 is aligned with the fastening hole 102 on the side plate 101 and connected by aluminum mold pins.

[0030] Then, when installing the prefabricated composite slab 3, before lifting the composite slab 3, the auxiliary installation marks on the composite slab 3 need to be checked. The auxiliary installation marks of the composite slab 3 are made in the factory according to the design drawings to prevent incorrect hoisting direction on site. When lifting the composite slab 3, it is advisable to use a hoisting frame. It is required that four or six lifting points be evenly stressed during hoisting. The hoisting should be slow to ensure that the composite slab 3 is lifted steadily. Then, the composite slab 3 is hoisted to the installation position, slowly lowered and accurately placed on the support system and aluminum formwork body 1, so that the edge of the composite slab 3 is aligned with the beam formwork or wall formwork. The joints between adjacent composite slabs should be tight. When the composite slab 3 is placed on the aluminum formwork body 1, the hollow rubber strip 203 is compressed and undergoes elastic deformation, so that the hollow rubber strip 203 can fill the small gap in the joint between the support surface of the aluminum formwork body 1 and the composite slab 3, preventing grout leakage and the formation of slag inclusions.

[0031] Reference Figure 2 As shown, the aluminum mold body 1 is C-shaped, and side plates 101 are connected to both sides of the aluminum mold body 1. Multiple fastening holes 102 are provided on the side plates 101. The bonding plate 4 is U-shaped, and both sides of the bonding plate 4 are closely attached to one side of the side plate 101. Multiple connecting holes 404 are provided on the bonding plate 4, and the positions of the multiple connecting holes 404 correspond to the fastening holes 102.

[0032] After the bonding plate 4 is installed on the aluminum mold body 1, two adjacent aluminum mold bodies 1 can be pressed together and connected by aluminum mold pins passing through the remaining fastening holes 102 and connecting holes 404. At this time, the two adjacent bonding plates 4 are pressed together, which squeezes the sealing strip 402, causing the sealing strip 402 to deform elastically and block the gap between the two bonding plates 4 to prevent grout leakage.

[0033] Reference Figure 8 As shown, the metal slot 201 is U-shaped, and two symmetrically arranged protrusions 202 are connected to the inner side of the metal slot 201. The protrusions 202 prevent the hollow adhesive strip 203 from detaching from the metal slot 201.

[0034] Reference Figure 2 and Figure 7 As shown, the sealing groove 401 corresponds to the groove 2. The top of the bonding plate 4 has two notches 403 that communicate with the sealing groove 401. The bottom wall of the notch 403 is flush with the bottom wall of the iron slot 201. The width of the notch 403 is smaller than the width of the iron slot 201, so that the bonding plate 4 can limit the iron slot 201 in the groove 2. The length of the iron slot 201 is adapted to the length of the groove 2. The length of the hollow adhesive strip 203 is greater than the length of the iron slot 201. Both ends of the hollow adhesive strip 203 extend into the notch 403, and the top of the sealing adhesive strip 402 contacts the bottom surface of the hollow adhesive strip 203.

[0035] By setting the notch 403, both ends of the hollow rubber strip 203 can extend into the notch 403 and contact the top of the sealing strip 402, so that the sealing strip 402 and the hollow rubber strip 203 form a U-shaped barrier to prevent slurry leakage.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
