Description

Technical Field

[0001] The utility model relates to the technical field of laminated floor construction, in particular to a slurry leakage prevention device for precast laminated plate joint construction. Background Art

[0002] A laminated plate is an assembled integral floor slab formed by laminating a precast plate and a cast-in-place reinforced concrete layer. The laminated floor has good integrity, and the upper and lower surfaces of the plate are flat, which is convenient for the decoration of the finishing layer, and is suitable for high-rise buildings and large-span buildings with high requirements for overall stiffness.

[0003] After retrieval, the patent with the application number CN201821144076.1 discloses an energy-saving precast component laminated plate splicing structure, including a first clamping plate and a connecting plate. Fixed plates are fixedly installed on both sides of the first clamping plate, threaded holes are fixedly installed inside the fixed plates, a fixed bracket is fixedly installed inside the connecting plate, the connecting plate is located on the right side of the threaded hole, and a second clamping plate is fixedly installed below the connecting plate; by setting steel clamping plates in the utility model, steel clamping plates are installed between the first clamping plate and the second clamping plate installed between devices. The steel clamping plates can vertically arrange the stress bars of the plate, evenly transmit the weight borne to the steel clamping plates, fix the positions of the steel clamping plates, and resist the temperature deformation caused by thermal expansion and contraction, and play a role in connecting the masonry to prevent cracking when placed in the brick layer, so as to improve the stability between devices, and the steel clamping plates are in a net structure and can be well heat-dissipated.

[0004] However, the two groups of laminated plates are supported by templates, and the templates and the laminated plates are sealed by pasting foam tapes on the surface of the templates. The viscosity of the foam tapes decreases when they encounter water, and a large amount of slurry is contained in the concrete. During the pouring process, the slurry in the concrete will penetrate through the foam tapes, resulting in a decrease in the sealing effect of the foam tapes on the joints of the precast laminated plates, causing the mortar to leak out from the joints, which will affect the pouring quality of the concrete.

[0005] Therefore, to solve the above problems, a slurry leakage prevention device for precast laminated plate joint construction is proposed. Summary of the Utility Model

[0006] In order to solve the above problems existing in the prior art, the utility model provides a slurry leakage prevention device for precast laminated plate joint construction.

[0007] The technical solution of the utility model is as follows:

The transverse frame bars are symmetrically arranged on the upper surface of the precast composite slab bodies, and the end face bars are equidistantly distributed around the side walls of the precast composite slab bodies. A support formwork is movably arranged at the bottom of the post-cast strip groove. A rubber cushion plate is laid on the upper surface of the support formwork. Fixed hanging brackets are movably arranged at positions corresponding to the end face bars on the upper surface of the rubber cushion plate, and foam tapes are pasted at both ends of the rubber cushion plate.

[0012] Preferably, fixing grooves are formed at positions corresponding to the fixed hanging brackets on the upper surface of the rubber cushion plate. The fixing grooves are in a right-angle structure, and the bottom of the fixed hanging bracket is inserted into the fixing groove.

[0013] Preferably, the fixed hanging brackets are symmetrically distributed, and hanging holes are formed through the surfaces of the fixed hanging brackets. The hanging holes are inserted into the end face bars.

[0014] Preferably, limiting grooves are formed on both sides of the upper surface of the support formwork for accommodating the lower tape.

[0017] 2. The utility model adopts a fixed hanger that is plugged into the end ribs through a hanging hole. The prefabricated composite plate is pressed on the side of the rubber pad under the action of gravity. When disassembling, the rubber pad is torn off, and the fixing groove is torn, so that the rubber pad and the fixed hanger can be quickly separated.

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.

[0025] See also Figures 1 to 4 A slurry leakage prevention device for prefabricated composite panel joint construction comprises a prefabricated composite panel body 1, cross frame reinforcement 2, end reinforcement 3 and post-casting strip groove 4. The prefabricated composite panel body 1 is symmetrically arranged, and a post-casting strip groove 4 is formed between two groups of prefabricated composite panel bodies 1. The cross frame reinforcement 2 is symmetrically arranged on the upper surface of the prefabricated composite panel 1, and the end reinforcement 3 is equidistantly distributed around the side wall of the prefabricated composite panel body 1. A supporting template 5 is movably provided at the bottom of the post-casting strip groove 4, and a rubber pad 6 is laid on the upper surface of the supporting template 5. Fixed brackets 7 are movably provided at the upper surface of the rubber pad 6 corresponding to the position of the end reinforcement 3, and foam tapes 10 are pasted on both ends of the rubber pad 6.

[0026] Furthermore, the foam tape 10 has a Z-shaped structure.

[0027] Further, the foam tape 10 includes an upper tape 11 and a lower tape 12. The upper tape 11 is adhered to the lower surface of the prefabricated laminated plate body 1, and the lower tape 12 is adhered to the lower surface of the rubber cushion plate 6. Both sides of the rubber cushion plate 6 are respectively abutted against the connection part of the upper tape 11 and the lower tape 12.

[0028] When formwork is erected for the support formwork 5, the foam tape 10 is adhered to both sides of the upper surface of the support formwork 5. The lower tape 12 is respectively adhered in the limit grooves 13, and the rubber cushion plate 6 is laid flat on the surface of the support formwork 5. After the prefabricated laminated plate body 1 is hoisted, the fixed hanging bracket 7 is inserted into the end face reinforcement 3 through the hanging holes 8. The prefabricated laminated plate body 1 presses on the side of the rubber cushion plate 6 under the action of gravity, which can realize the rapid installation of the rubber cushion plate 6. At this time, both sides of the lower surface of the rubber cushion plate 6 are adhered to the upper surface of the lower tape 12. At the same time, the prefabricated laminated plate body 1 presses on the upper tape 11 under the action of gravity. Both sides of the rubber cushion plate 6 are respectively abutted against the connection part of the upper tape 11 and the lower tape 12. The rubber cushion plate 6 is relatively soft. After being heavily pressed by the prefabricated laminated plate body 1, the upper surface of the rubber cushion plate 6 can be deformed and fully adhered to the connection part of the prefabricated laminated plate body 1. The slurry needs to pass through the connection part between the rubber cushion plate 6 and the prefabricated laminated plate body 1 and can only leak after passing through the connection parts between the upper tape 11 and the lower tape 12 and the prefabricated laminated plate body 1 and the support formwork 5 respectively, which can effectively avoid the phenomenon of slurry leakage during use.

[0029] See Figure 2 and Figure 4 , the fixed hanging brackets 7 are symmetrically distributed, and hanging holes 8 are all penetrated through the surface of the fixed hanging brackets 7. The hanging holes 8 are inserted into the end face reinforcement 3. Both sides of the rubber cushion plate 6 are pressed under the prefabricated laminated plate body 1, and the lower surface of the prefabricated laminated plate body 1 is adhered to the upper surface of the rubber cushion plate 6. Fixed grooves 9 are opened at the positions corresponding to the positions of the fixed hanging brackets 7 on the upper surface of the rubber cushion plate 6. The fixed grooves 9 are in a right-angle structure, and the bottom of the fixed hanging brackets 7 is inserted into the fixed grooves 9.

[0030] During disassembly, by tearing the rubber cushion plate 6, the fixed grooves 9 are torn, which can quickly separate the rubber cushion plate 6 from the fixed hanging brackets 7. The exposed part of the fixed hanging brackets 7 can be cut by a cutting machine to realize the rapid disassembly of the rubber cushion plate 6.

[0031] See Figure 2 and Figure 4 , it can also be known that limit grooves 13 are opened on both sides of the upper surface of the support formwork 5 for accommodating the lower tape 12, which can make the support formwork 5 fully adhered to the rubber cushion plate 6 to ensure the support stability at the joint of the prefabricated laminated plates. A limit protrusion 14 is integrally formed in the middle of the upper surface of the support formwork 5, and the limit protrusion 14 is located between the two groups of lower tapes 12.

[0032] Working principle of the utility model:

[0033] In the utility model, when formwork is erected for the supporting formwork 5, the foam tape 10 is pasted on both sides of the upper surface of the supporting formwork 5, the lower tape 12 is respectively pasted in the limiting groove 13, and the rubber cushion plate 6 is laid flat on the surface of the supporting formwork 5. After the precast composite slab body 1 is hoisted, the fixed hanging bracket 7 is inserted into the end face reinforcement 3 through the hanging hole 8. The precast composite slab body 1 presses on the side of the rubber cushion plate 6 under the action of gravity, which can realize the rapid installation of the rubber cushion plate 6. At this time, both sides of the lower surface of the rubber cushion plate 6 are pasted on the upper surface of the lower tape 12. At the same time, the precast composite slab body 1 presses on the upper tape 11 under the action of gravity. Both sides of the rubber cushion plate 6 respectively abut against the connection part of the upper tape 11 and the lower tape 12. The rubber cushion plate 6 is relatively soft. After being heavily pressed by the precast composite slab body 1, the upper surface of the rubber cushion plate 6 can be deformed and fully fit with the connection part of the precast composite slab body 1. The slurry needs to pass through the connection part between the rubber cushion plate 6 and the precast composite slab body 1 and can leak only after passing through the connection parts of the upper tape 11 and the lower tape 12 with the precast composite slab body 1 and the supporting formwork 5 respectively, which can effectively avoid the phenomenon of slurry leakage during use. The fixed hanging bracket 7 is made of metal and is fixed by being inserted into the fixed groove 9 at the bottom. During disassembly, by tearing the rubber cushion plate 6, the fixed groove 9 is torn, so that the rubber cushion plate 6 can be quickly separated from the fixed hanging bracket 7. The exposed part of the fixed hanging bracket 7 can be cut by a cutting machine to realize the rapid disassembly of the rubber cushion plate 6.
