Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an integrated device for splicing-free support and side formwork of composite beams and slabs. Background Technology

[0002] Both the composite beams and composite slabs are precast. During construction, the composite beams and composite slabs are spliced ​​together, and then a cast-in-place layer is poured on top of the composite slabs to connect the composite slabs and composite beams. The composite beams and composite slabs are supported at the bottom, but the joints between them need to be sealed first. Current practice involves using mesh fabric and expansive concrete to treat the joints of the composite beams and slabs.

[0003] For example, the national authorized patent announcement number CN216810337U discloses a sealing structure for the joints of composite beams and slabs, including: a sealing member attached to the joint of the composite beams and slabs, the sealing member sealing the joint of the composite beams and slabs; a support member supported at the bottom of the sealing member and arranged in an inclined shape, the length of the support member being adjustable, and the other end of the support member being securely connected to a support frame under the composite slab. This utility model's sealing structure can be reused, has a simple structure, is easy to install and dismantle, has low construction difficulty, and good on-site construction effect. Compared with existing methods of sealing joints using mesh cloth and expansive concrete, it has the advantages of shorter construction time and higher construction efficiency.

[0004] However, the sealing structure mentioned above for the joints of composite beams and slabs cannot automatically seal the joints during the assembly of the composite slabs and side formwork. Instead, after the composite slabs and side formwork are assembled, special construction personnel are required to seal the joints. This increases the construction process and time costs, reduces the overall construction efficiency, and cannot meet the needs of rapid construction. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated device for splicing composite beams and slabs without joints and side formwork, so as to solve the problem mentioned in the background art that the splicing joints cannot be automatically sealed during the assembly of composite beams and slabs with side formwork.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A composite beam-slab jointless support and side formwork integrated device includes: a composite beam-slab body and a side formwork. The upper surface of the composite beam-slab body has insertion ports at both ends, into which U-shaped inserts can be inserted. The U-shaped inserts are fixedly installed on the upper surface of the side formwork. A top sealing mechanism is slidably inserted into the U-shaped inserts, so that when the top sealing mechanism is pressed down by the composite beam-slab body, it can automatically extend to both ends of the U-shaped inserts, thereby allowing the top sealing mechanism to extend and contact the joint between the insertion ports and the U-shaped inserts.

[0008] Preferably, the top sealing mechanism includes a pressure plate, which is slidably installed inside the side plate mold and slides through the upper surface of the side plate mold. A connecting rod is rotatably installed on the lower surface of the pressure plate, and a push plate is rotatably installed on the outer surface of the other end of the connecting rod. The push plate slides inside the U-shaped insert, and the upper surface of the push plate slides through the U-shaped insert.

[0009] Preferably, a connecting block is rotatably mounted on the outer surface of the middle section of the connecting rod. The connecting block is fixedly installed on the lower surface of the side plate mold and is flush with the lower surfaces of the pressure plate and the push plate. This allows the connecting rod to be pushed down to lift the push plate when the pressure plate is pressed down by the composite beam body.

[0010] Preferably, a rotating frame is fixedly installed on the upper surface of the push plate, a connecting arm is rotatably installed inside the rotating frame, and a rubber sealant column is fixedly installed at one end of the connecting arm.

[0011] Preferably, both ends of the connecting arm are provided with traction grooves, and the connecting arm slides between the docking plates through the traction grooves. The docking plates are fixedly installed on the upper surface of the U-shaped insert.

[0012] Preferably, the lifting push plate can push the connecting arm through the traction grooves on both sides to rotate and extend within the docking plate, and the rotated and extended connecting arm can drive the rubber sealant column to fill and contact the joint between the insertion port and the U-shaped insert.

[0013] Preferably, the outer wall of the U-shaped insert is provided with anti-slip protrusions, which contact the inner wall of the insertion port.

[0014] Preferably, the insertion port edge of the composite beam plate is provided with an elastic buffer pad.

[0015] Preferably, the connecting rod is an aluminum alloy connecting rod, and its surface is coated with an epoxy resin anti-rust coating, the thickness of which is 0.1-0.3mm.

[0016] Preferably, the inner wall of the traction groove is fitted with a low-friction coefficient bushing.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] Through the design of the composite beam slab, insertion ports, side plate molds, U-shaped inserts, and top sealing mechanism, when the composite beam slab and side plate molds are assembled together, the U-shaped inserts of the side plate molds can be inserted into the insertion ports opened at both ends of the composite beam slab. After the U-shaped inserts are fully inserted, the top sealing mechanism sliding out from the side plate molds is pressed down by the composite beam slab. The top sealing mechanism, under pressure, can extend and unfold upwards within the U-shaped inserts, and the extended top sealing mechanism can then contact the insertion port and the U-shaped insert. The joints between the components are sealed, which automatically seals the joints during assembly. The tight fit between the U-shaped inserts and the insertion ports makes the connection between the composite beam slab and the side plate formwork more compact and stable. During concrete pouring and subsequent use, it can better withstand various loads, ensuring the stability and safety of the structure. It can also effectively prevent grout leakage during concrete pouring, ensuring the forming quality of concrete components and avoiding quality problems such as honeycomb and pitting caused by grout leakage.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4This embodiment provides an integrated device for splice-free support and side formwork of composite beams and slabs, including: a composite beam and slab body 1 and a side formwork 2. Both ends of the upper surface of the composite beam and slab body 1 are provided with insertion ports 101, and U-shaped inserts 201 can be inserted into the insertion ports 101. The U-shaped inserts 201 are fixedly installed on the upper surface of the side formwork 2. A top sealing mechanism 3 is slidably inserted into the U-shaped inserts 201, so that the top sealing mechanism 3 can automatically extend to both ends of the U-shaped inserts 201 after being pressed down by the composite beam and slab body 1, so that the top sealing mechanism 3 can extend and touch the splice between the insertion ports 101 and the U-shaped inserts 201.

[0026] Through the design of the composite beam plate 1, insertion port 101, side plate mold 2, U-shaped insert 201, and top sealing mechanism 3, when the composite beam plate 1 and side plate mold 2 are assembled together, the U-shaped insert 201 of the side plate mold 2 can be inserted into the insertion ports 101 opened at both ends of the composite beam plate 1. After the U-shaped insert 201 is fully inserted, the top sealing mechanism 3, which slides out from the side plate mold 2, is pressed down by the composite beam plate 1. The top sealing mechanism 3, which is pressed down, can extend and unfold upward within the U-shaped insert 201, and the extended top sealing mechanism 3 can then touch the insertion port 101. The joint between the insertion port 101 and the U-shaped insert 201 is sealed, which realizes the automatic sealing of the joint during the assembly process. Through the tight fit between the U-shaped insert 201 and the insertion port 101, the connection between the composite beam slab 1 and the side plate mold 2 is made tighter and more stable. During concrete pouring and subsequent use, it can better withstand various loads, ensure the stability and safety of the structure, and effectively prevent grout leakage during concrete pouring, ensuring the molding quality of concrete components and avoiding quality problems such as honeycomb and pitting caused by grout leakage.

[0027] like Figures 3-4 As shown, the top sealing mechanism 3 includes a pressure plate 301, which is slidably installed inside the side plate mold 2 and slides out from the upper surface of the side plate mold 2. A connecting rod 302 is rotatably installed on the lower surface of the pressure plate 301, and a push plate 303 is rotatably installed on the outer surface of the other end of the connecting rod 302. The push plate 303 slides inside the U-shaped insert 201, and the upper surface of the push plate 303 slides out from inside the U-shaped insert 201.

[0028] A connecting block 202 is rotatably mounted on the outer surface of the middle section of the connecting rod 302. The connecting block 202 is fixedly installed on the lower surface of the side plate mold 2 and is flush with the lower surfaces of the pressure plate 301 and the push plate 303. This allows the connecting rod 302 to be pushed down and the push plate 303 to be lifted when the pressure plate 301 is pressed down by the composite beam plate 1.

[0029] A rotating frame 304 is fixedly installed on the upper surface of the push plate 303. A connecting arm 305 is rotatably installed inside the rotating frame 304. A rubber sealant column 306 is fixedly installed at one end of the connecting arm 305. Both ends of the connecting arm 305 are provided with traction grooves 307. The connecting arm 305 slides between the docking plates 203 through the traction grooves 307. The docking plates 203 are fixedly installed on the upper surface inside the U-shaped insert 201, so that the push plate 303, which is lifted up, can push the connecting arm 305 through the traction grooves 307 on both sides to rotate and extend inside the docking plate 203. The rotated and extended connecting arm 305 can drive the rubber sealant column 306 to fill and contact the joint between the insertion port 101 and the U-shaped insert 201.

[0030] Through the design of the pressure plate 301, push plate 303, connecting arm 305, rubber sealant column 306, and traction groove 307, when the side plate mold 2 is inserted into the insertion port 101 of the composite beam plate 1 via the U-shaped insert 201, the pressure plate 301 sliding out of the side plate mold 2 will be subjected to downward pressure from the composite beam plate 1. This pressure continues until the U-shaped insert 201 is fully inserted into the insertion port 101, which in turn presses the pressure plate 301 into the side plate mold 2. The pressed-in pressure plate 301 then drives the connecting... The rod 302 flips downward within the connecting block 202, causing the other end of the connecting rod 302 to tilt upward. This allows the connecting rod 302 to lift the push plate 303, which is rotatably mounted on its outer surface. The lifted push plate 303 then pushes the connecting arm 305 through the traction grooves 307 on both sides, causing it to flip and flatten within the mating plate 203. The connecting arm 305, which has flipped from an upward tilted position to a horizontal position, extends in length. This extended connecting arm 305 can then drive... The rubber sealant column 306 automatically seals the joint between the insertion port 101 and the U-shaped insert 201 by pressing against the joint. Driven by the connecting arm 305, the rubber sealant column 306 precisely presses against the joint to form a good seal, effectively preventing grout leakage during concrete pouring, ensuring the quality of concrete pouring, and avoiding quality problems such as uneven concrete surface and honeycomb pitting caused by grout leakage. In addition, during the main installation action of inserting the side plate mold 2 into the insertion port 101 of the composite beam slab 1, the sealing treatment of the joint is completed automatically and simultaneously, reducing construction procedures and operation time, improving construction efficiency, reducing labor costs and labor intensity. Furthermore, the downward pressure of the rubber sealant column 306 can also prevent the U-shaped insert 201 from coming out of the inside of the insertion port 101, thereby improving the integrity and stability of the composite beam slab 1 structure and helping to improve the overall performance of the building structure.

[0031] The outer wall of the U-shaped insert 201 is provided with anti-slip protrusions, which contact the inner wall of the insertion port 101 to enhance the stability of the U-shaped insert 201 after insertion.

[0032] Among them, the edge of the insertion port 101 of the composite beam plate 1 is provided with an elastic buffer pad. The buffer pad is made of silicone rubber and is used to buffer the impact force when the U-shaped insert 201 is inserted.

[0033] Among them, the connecting rod 302 is an aluminum alloy connecting rod, and the surface is coated with an epoxy resin anti-rust coating. The thickness of the epoxy resin anti-rust coating is 0.1-0.3mm, which is used to improve the corrosion resistance of the connecting rod 302 in humid environments.

[0034] The inner wall of the traction groove 307 is embedded with a low-friction coefficient bushing made of polytetrafluoroethylene, which is used to reduce the frictional resistance when the connecting arm 305 slides.

[0035] Based on the above technical solution, the working steps of this solution are summarized as follows: When assembling the composite beam plate 1 and the side plate mold 2 together, the U-shaped insert 201 of the side plate mold 2 can be inserted into the insertion holes 101 opened at both ends of the composite beam plate 1. After the U-shaped insert 201 is fully inserted, the pressure plate 301 sliding out from the side plate mold 2 can be subjected to the downward pressure of the composite beam plate 1. After the U-shaped insert 201 is fully inserted into the insertion hole 101, it will also press the pressure plate 301 into the side plate mold 2. The pressed-in pressure plate 301 can drive the connecting rod 302 to rotate downward in the connecting block 202, thereby causing the other end of the connecting rod 302 to tilt upward, which can cause the outer surface of the connecting rod 302 to rotate and install. The push plate 303 is lifted up, which allows the pusher arm 305 to be pushed through the traction grooves 307 on both sides to flip and flatten within the docking plate 203. The connecting arm 305, which flips from an upward tilted position to a horizontal position, can extend its length. The flipped and extended connecting arm 305 can drive the rubber sealant column 306 to fill and contact the joint between the insertion port 101 and the U-shaped insert 201, thus realizing automatic filling of the joint between the insertion port 101 and the U-shaped insert 201. The rubber sealant column 306, driven by the connecting arm 305, accurately contacts the joint, forming a good seal, effectively preventing grout leakage during concrete pouring and ensuring the quality of concrete pouring.

[0036] In summary: During the main installation process of inserting the side plate mold 2 into the insertion port 101 of the composite beam slab 1, the sealing treatment of the joint is completed automatically and simultaneously, reducing construction procedures and operation time, improving construction efficiency, and reducing labor costs and labor intensity.

[0037] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
