Description

TECHNICAL FIELD

[0001] The application relates to the technical field of fabricated buildings, in particular to an aluminum formwork support device for fabricated composite slab construction. BACKGROUND

[0002] The composite slab is a fabricated monolithic floor slab composed of a prefabricated slab and a cast-in-place reinforced concrete layer; the composite slab, as an important component in the fabricated building, can not only improve the construction efficiency, but also effectively improve the overall assembly rate of the building.

[0003] At present, when the composite slab is constructed, the aluminum formwork needs to be first constructed on the construction site, and then the construction of the composite slab is carried out on the basis of the aluminum formwork; the existing aluminum formwork support system usually comprises an aluminum formwork and a support column for supporting the aluminum formwork, wherein the aluminum formwork is abutted against the two sides of the composite slab for support, and the adjacent composite slabs need to be poured with concrete for connection.

[0004] During the on-site construction, the aluminum formwork surface and the bottom surface of the composite slab cannot be well matched, and therefore, when the concrete is poured between the two composite slabs, the concrete may leak from the gap between the two composite slabs, thereby affecting the on-site construction quality, and further improvement is needed. CONTENT OF THE INVENTION

[0005] In order to reduce the possibility of concrete leakage from the gap between the two composite slabs when the concrete is poured between the two composite slabs, the application provides an aluminum formwork support device for fabricated composite slab construction.

[0006] The application provides an aluminum formwork support device for fabricated composite slab construction, which adopts the following technical scheme:

[0007] The aluminum formwork support device for fabricated composite slab construction comprises a base, a support rod arranged on the base, and an aluminum formwork arranged on the upper end of the support rod and used for supporting the composite slab; one aluminum formwork is used for supporting two adjacent composite slabs, and a pouring space for subsequent concrete pouring is left between the two adjacent composite slabs and the aluminum formwork; the concrete is solidified to form a connecting layer; the upper surface of the aluminum formwork is provided with a leakage prevention assembly; the leakage prevention assembly comprises an elastic strip arranged on the upper surface of the aluminum formwork and a rubber belt arranged outside the elastic strip and used for isolating the concrete; and the rubber belt is abutted against the lower surface of the composite slab.

[0008] By adopting the technical scheme, the gap between the laminated slab and the aluminum formwork is filled after being extruded by the elasticity of the elastic strip, thereby reducing the possibility of concrete leakage in subsequent pouring, and the adhesive tape is arranged to isolate the elastic strip and the concrete, thereby reducing the possibility of adhesion between the elastic strip and the concrete after the concrete dries and affecting the compression or rebound of the subsequent elastic strip, so that the elastic strip can be repeatedly used. Moreover, the adhesive tape is convenient to replace after being bonded with the concrete, and the cost is relatively low compared with replacing the elastic strip.

[0009] Preferably, the leak-proof assembly is provided with two and abuts against the lower surfaces of the two adjacent laminated slabs.

[0010] By adopting the technical scheme, if one aluminum formwork is provided with one leak-proof assembly and two laminated slabs abut against one elastic strip, the middle part of the elastic strip is likely to be convex, and the lower surface is likely to be concave and need to be filled after subsequent pouring of concrete and drying. However, the adhesion effect of the subsequent patching concrete is likely to be poor due to the influence of gravity, thereby affecting the appearance flatness. Therefore, two leak-proof assemblies are arranged to abut against the lower surfaces of the two adjacent laminated slabs, so that the lower surface of the concrete is relatively convex to the lower surface of the laminated slab, and the convex part can be polished to make the appearance relatively flat.

[0011] Preferably, the adhesive tape comprises an abutting portion abutting against the lower surface of the laminated slab, two connecting portions respectively arranged on both sides of the abutting portion, and two bonding portions respectively arranged at one end of the two connecting portions away from the abutting portion, the bonding portions are used for bonding the upper surface of the aluminum formwork, and the mounting space for mounting the elastic strip is formed between the adhesive tape and the aluminum formwork.

[0012] By adopting the technical scheme, the two bonding portions are arranged at one end of the two connecting portions away from the abutting portion, so as to improve the bonding effect between the adhesive tape and the aluminum formwork, and the adhesive tape is not easy to fall off.

[0013] Preferably, the bonding portions arranged on the same aluminum formwork are fixedly connected to each other, and the upper surfaces of the bonding portions abut against the lower surface of the connecting layer.

[0014] By adopting the technical scheme, the bonding portions arranged on the same aluminum formwork are fixedly connected to each other, which can be used for isolating the aluminum formwork and the concrete, thereby reducing the possibility of removing the concrete bonded on the aluminum formwork and reducing the time for removing the concrete bonded on the aluminum formwork.

[0015] Preferably, the opposite surfaces of the abutting portion are provided with adhesive layers, respectively bonded to the laminated slab and the elastic strip.

[0016] By adopting the technical scheme, the adhesive layer is arranged to improve the adhesion between the adhesive tape, the laminated board and the elastic strip, and to reduce the possibility of relative sliding between the abutting portion and the laminated board.

[0017] Preferably, the width of the connecting portion is greater than the width of the elastic strip in the height direction.

[0018] By adopting the technical scheme, the width of the connecting portion is greater than the width of the elastic strip in the height direction, so that the mounting space for mounting the elastic strip between the adhesive tape and the aluminum formwork is relatively large. Due to the relatively small length between the two connecting portions and the abutting portion in the adhesive tape, the volume of the mounting space formed by the elastic strip will decrease when the elastic strip is extruded. Since the volume change of the elastic strip after extrusion is not necessarily the same as the change of the mounting space, the width of the connecting portion is greater than the width of the elastic strip in the height direction to reduce the influence on the deformation change of the subsequent elastic strip when extruded.

[0019] Preferably, the leak-proof assembly further comprises a pushing member for pushing the elastic strip to move towards the laminated board.

[0020] By adopting the technical scheme, the elastic strip will deform to a certain extent when the laminated board is extruded for a long time. The pushing member is arranged to push the elastic strip to abut against the laminated board to improve the sealing effect between the elastic strip and the laminated board, thereby reducing the possibility of slurry leakage.

[0021] Preferably, the pushing member comprises a first air bag arranged below the adhesive portion, a connecting channel arranged on the first air bag, and a second air bag arranged in communication with the connecting channel, the second air bag being arranged below the elastic strip, and the first air bag being arranged below the connecting layer.

[0022] By adopting the technical scheme, the first air bag is arranged below the connecting layer. When the concrete is poured, the air in the first air bag will flow into the second air bag through the connecting channel to extrude the elastic strip, thereby further improving the sealing effect between the elastic strip and the laminated board and further reducing the possibility of slurry leakage.

[0023] Preferably, the leak-proof assembly further comprises a connecting member, the pushing member is detachably connected to the aluminum formwork through the connecting member, and the elastic strip is also detachably connected to the pushing member or the aluminum formwork through the connecting member.

[0024] By adopting the technical scheme, the elastic element is arranged first to reduce the possibility of concrete leakage, and the connecting element is arranged to install the pushing element on the aluminum formwork to push the elastic strip to move towards the direction of the composite board, so that the elastic strip can still be used after deformation.

[0025] In summary, the utility model has the following beneficial effects:

[0026] The elastic strip itself is elastic to fill the gap between the composite board and the aluminum formwork after being extruded, thereby reducing the possibility of concrete leakage during subsequent pouring. The adhesive tape is arranged to isolate the elastic strip and the concrete, thereby reducing the possibility of adhesion between the elastic strip and the concrete after the concrete dries, which is not easy to separate and affects the compression or rebound of the subsequent elastic strip. The elastic strip can be repeatedly used. The adhesive tape is easy to replace after being bonded with the concrete, and the cost is relatively low compared with replacing the elastic strip.

DETAILED DESCRIPTION

[0034] The following will be described in detail in combination with the accompanying Figures 1-6 The present application will be further described in detail.

[0035] This application discloses an aluminum formwork support device for prefabricated composite slab construction.

[0036] Example 1:

[0037] An aluminum formwork support device for prefabricated composite slab construction, referring to Figure 1 The support device is provided in several parts, depending on the requirements. The support device specifically includes a base 1 for contacting the ground, a support rod 2 fixedly connected to the base 1, and an aluminum template 3 fixedly connected to the upper end of the support rod 2 for supporting the composite plate 4.

[0038] In this embodiment, an aluminum formwork 3 is used to support two adjacent composite slabs 4. A pouring space is left between the two adjacent composite slabs 4 and between the aluminum formwork 3 for subsequent concrete pouring. After the concrete solidifies, a connecting layer 6 is formed.

[0039] Reference Figure 1 , Figure 2 In this embodiment, to reduce the possibility of grout leakage, the upper surface of the aluminum formwork 3 is provided with a leak-proof component 5. There are two leak-proof components 5, which abut against the lower surfaces of two adjacent composite plates 4 respectively. The leak-proof component 5 includes an elastic strip 51 provided on the upper surface of the aluminum formwork 3, an adhesive tape 52 provided outside the elastic strip 51 to isolate the concrete, and a connector 53 for making the elastic strip 51 detachably connected to the aluminum formwork 3.

[0040] The elastic strip 51 can be made of sponge or rubber, depending on the requirements, and its cross-section is rectangular. In this embodiment, the connector 53 is specifically double-sided adhesive. The two surfaces of the double-sided adhesive are respectively bonded to the elastic strip 51 and the aluminum template 3 to bond the elastic strip 51 to the upper surface of the aluminum template 3.

[0041] The tape 52 abuts against the lower surface of the composite plate 4, forming an installation space between the tape 52 and the aluminum template 3 for installing the elastic strip 51. The tape 52 specifically includes an abutting portion 521 abutting against the lower surface of the composite plate 4, two connecting portions 522 respectively disposed on both sides of the abutting portion 521, and an adhesive portion 523 disposed at the end of the connecting portion 522 away from the abutting portion 521. Adhesive layers are provided on both opposite surfaces of the abutting portion 521 to adhere to the surfaces of the composite plate 4 and the elastic strip 51 that are close to each other. The width of the connecting portion 522 is greater than the width of the elastic strip 51 in the height direction to accommodate the volume change of the elastic strip 51 after compression deformation. It should be noted that the connecting portion 522 can be wavy along its width direction or arc-shaped in the direction away from the elastic strip 51, so that the width of the connecting portion 522 is greater than the height of the elastic strip 51 in the height direction, depending on the requirements.

[0042] In the embodiment, the adhesive part 523 is specifically provided with two, which are respectively arranged at one end of the two connecting parts 522 away from the abutting part 521, and the adhesive part 523 is used to fix the upper surface of the aluminum formwork 3. For the fixing between the adhesive part 523 and the aluminum formwork 3, the adhesive part 523 can be arranged at the side of the connecting part 522 away from the elastic strip 51, so that the adhesive tape 52 is arranged in the shape of Ω, as shown in Figure 2 ; or the adhesive part 523 away from the connecting layer 6 is bent to be below the elastic strip 51, connected with the connecting piece 53, and connected with the aluminum formwork 3, and the adhesive part 523 close to the connecting layer 6 is below the connecting layer 6, as shown in Figure 3 ; or the two adhesive parts 523 are overlapped to be adhered to the aluminum formwork 3, so that the adhesive tape 52 is arranged in the shape of a mouth, and the elastic strip 51 is connected with the adhesive part 523 through the connecting piece 53, as shown in Figure 4 . It should be noted that the final state of the adhesive tape 52 is specifically set according to the requirements, and in the embodiment, the adhesive tape 52 arranged in the shape of Ω is specifically shown.

[0043] Referring to Figure 5 , further, the adhesive parts 523 arranged on the same aluminum formwork 3 and close to each other can be fixedly connected, so that the upper surface of the adhesive part 523 abuts against the lower surface of the connecting layer 6, reduces the possibility of adhesion between the aluminum formwork 3 and the concrete when the concrete directly contacts the aluminum formwork 3, and reduces the time spent on removing the adhered and solidified concrete when the aluminum formwork 3 is used again.

[0044] The implementation principle of the aluminum formwork support device for the fabricated composite slab 4 construction in the embodiment is that the gap between the composite slab 4 and the aluminum formwork 3 is filled after being extruded by the elasticity of the elastic strip 51 itself, so as to reduce the possibility of slurry leakage of the subsequent pouring concrete, and the adhesive tape 52 is arranged to isolate the elastic strip 51 and the concrete, so as to reduce the possibility of adhesion between the elastic strip 51 and the concrete after the concrete is dried, which is not easy to separate and affects the compression or rebound of the elastic strip 51, so that the elastic strip 51 can be repeatedly used. And the adhesive tape 52 is also convenient to replace after being adhered with the concrete, and the cost is relatively lower than that of replacing the elastic strip 51.

[0045] Embodiment 2

[0046] Referring to Figure 6Different from the embodiment 1, the leakproof assembly 5 further comprises a pushing member 54 for pushing the elastic strip 51 to move towards the direction of approaching the laminated board 4, in the embodiment, the pushing member 54 specifically comprises a first air bag 541 arranged below the bonding part 523, a connecting channel 542 arranged on the first air bag 541 and a second air bag 543 arranged in communication with the connecting channel 542, the first air bag 541 and the second air bag 543 are both filled with air, the first air bag 541 is arranged below the connecting layer 6, and the second air bag 543 is arranged below the elastic strip 51, at this time, the elastic strip 51 is connected with the second air bag 543 through the connecting member 53, so that the elastic strip 51 is detachably connected with the pushing member 54 through the connecting member 53. The pushing member 54 is detachably connected with the aluminum formwork 3 through the connecting member 53.
