Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of formwork assemblies for concrete pouring, belong to concrete pouring field. BACKGROUND

[0002] Concrete pouring usually needs to use pouring formwork, pouring formwork plays the role of supporting, keeping the shape of concrete, improving construction efficiency, guaranteeing engineering quality and environmental protection and energy saving, and pouring formwork can also be recycled.

[0003] When pouring large volume of concrete members, due to the high hydration heat of cement, the hydration heat will accumulate inside and is not easy to dissipate, which will cause the internal temperature of the concrete member to rise significantly, while the surface of the concrete member dissipates heat quickly, which will form a large internal and external temperature difference, that is, the internal of the concrete member will produce compressive stress, and the surface of the concrete member will produce tensile stress, if the temperature difference is too large, cracks are easy to produce inside the concrete member.

[0004] Therefore, some pouring formworks with water cooling function have emerged, for example, a patent with authorization announcement No. CN217268899 U discloses a formwork assembly for concrete pouring, which comprises a formwork body and a plurality of threaded rods, the threaded rods are arranged in the formwork body and each threaded rod is movably arranged in two opposite sides of the formwork body, the two ends of each threaded rod extend out of the formwork body and are threadedly connected with a nut assembly, a sleeve is arranged outside each threaded rod, the formwork assembly for concrete pouring further comprises a water inlet pipe and a water outlet pipe, a water passage is coaxially arranged in each threaded rod, the two ends of each threaded rod form a water inlet end and a water outlet end respectively, the water inlet end of each threaded rod is connected with the water outlet end of the previous threaded rod through a connecting pipe, the water inlet end of the first threaded rod is connected with one end of the water inlet pipe, and the water outlet end of the last threaded rod is connected with one end of the water outlet pipe.

[0005] This technical solution sleeves a sleeve outside the threaded rod, after the cooling water flows through the threaded rod, the sleeve exchanges heat with the concrete that is undergoing hydration reaction, and the concrete is cooled to prevent cracks and cracks in the concrete member, in addition, the formwork body, threaded rods and water inlet pipe and other components can be easily disassembled to realize easy recycling, but the recycling rate of the formwork assembly is still lacking, mainly reflected in the low recycling rate of the sleeve, because: during pouring, the end of the sleeve abuts against the inner wall of the formwork body, therefore, after the formwork body is removed, the sleeve is completely inside the concrete member, the sleeve cannot provide a clamping point outside the concrete member for grasping and applying force to take it out of the concrete member, and if the inner wall of the sleeve is directly expanded and fixed by equipment, it is easy to damage the concrete member. SUMMARY

[0006] In view of the shortcomings of the prior art, this application provides a concrete casting formwork component with a higher recycling rate.

[0007] A formwork assembly for concrete pouring includes a detachable formwork body. The formwork body includes two opposing side frames. Multiple water-cooling pipes are passed through the two side frames. A sleeve is fitted onto each water-cooling pipe. Multiple assembly slots are provided on the inner sidewalls of the side frames. The sleeve includes a main pipe section for being disposed between the two side frames and a clamping section connected to the main pipe section and assembled in the corresponding assembly slot.

[0008] Preferably, the outer circumferential surface of the main pipe section is provided with a tearable layer.

[0009] Preferably, the tearable layer comprises one of a gauze layer and a sponge layer.

[0010] Preferably, the module body further includes a front frame side and a rear frame side connected to the side frame side.

[0011] In summary, this utility model has the following beneficial effects:

[0012] 1. The present invention has a higher recycling rate for the mold frame components. Attached Figure Description

[0013] Figure 1 This is a structural schematic diagram of the first type of formwork assembly for concrete pouring. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] Example:

[0016] A formwork assembly for concrete pouring, such as Figure 1 As shown in the prior art, the system includes a mold frame body 1, which is a detachable component for reuse. The mold frame body 1 includes two opposing side frame edges 11 and a front frame edge 14 and a rear frame edge 15 connected to the two side frame edges 11. The front frame edge 14 and the rear frame edge 15 are connected to the side frame edges 11 by fasteners. Multiple water-cooling pipes 2 pass through the two side frame edges 11, and sleeves 4 are fitted onto the water-cooling pipes 2. The water-cooling pipes 2 can be pulled out from the sleeves 4 and the side frame edges 11 for reuse. The two ends of the water-cooling pipes 2 form an inlet and an outlet, respectively. In use, the outlet of the water-cooling pipe 2 is connected to the inlet of an adjacent water-cooling pipe 2 via a connecting water pipe 3, thus forming a complete flow channel to dissipate heat from the concrete undergoing hydration.

[0017] Different from the prior art, the inner side wall of the side frame 11 is provided with a plurality of assembly grooves 12, the sleeve pipe 4 comprises a main pipe section 42 arranged between two side frames 11 and a clamping section 41 connected with the main pipe section 42 and assembled in the corresponding assembly groove 12.

[0018] When the concrete member is poured and the mold frame body 1 is removed from the surface of the concrete member, the clamping section 41 is exposed outside the concrete member, thereby providing a clamping position outside the concrete member for the clamping device to grab and apply force, so as to pull out the sleeve pipe 4 from the concrete member, and the sleeve pipe 4 can also be reused relative to the prior art, thereby improving the recycling rate of the mold frame assembly.

[0019] The outer circumferential surface of the main pipe section 42 is provided with a tearable layer, which is one of a gauze layer and a sponge layer. The tearable layer is connected to the outer circumferential surface of the main pipe section 42 by adhesion. The thickness of the tearable layer is as small as possible, preferably 1-3 mm. The tearable layer is not shown in the drawings. The presence of the tearable layer allows tearing when the sleeve pipe 4 is pulled out, thereby facilitating the pulling out of the sleeve pipe 4. If the tearable layer is absent, the outer circumferential surface of the main pipe section 42 is combined with the formed concrete member after pouring, and a large force is required to pull out the sleeve pipe 4.

[0020] The above embodiments only describe the preferred embodiments of the present application, and do not limit the concept and scope of the present application. Various modifications and improvements to the technical solutions of the present application made by those skilled in the art without departing from the design concept of the present application shall fall within the protection scope of the present application. The technical content claimed by the present application has been fully recorded in the claims.
