Abstract
Description
Technical Field
[0001] The utility model relates to the field of concrete construction technology, in particular to a novel composite ribbed floor slab combined mold. Background Art
[0002] The new composite multi-ribbed floor is a composite mold embedded according to certain rules, and a multi-ribbed floor is formed in the floor after the concrete is poured in place. It has a light weight and a large span, and can meet the needs of the current multi-story buildings with large column grids, large bays, and large spaces. The floor can not only provide flexible application space, but also has the advantages of reducing the weight of the structure, increasing the rigidity of the floor, shortening the construction period, improving the sound insulation effect, and reducing the structural cost. Its economic and technical indicators are significantly improved compared with other types of floor systems, so it has a wide range of application prospects. The existing technology mostly uses a single core mold. (1) The single core mold is greatly affected by the pouring. The small-sized core mold has a low vacuum rate, a large amount of concrete, and poor economy. The pouring of the large-sized core mold is not dense, and there are great safety hazards. (2) The single core mold is easy to swing and the molding effect is poor. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides a new composite dense-ribbed floor combination mold. When pouring concrete, the air below the combination mold can be smoothly vented to ensure that the concrete is poured densely and eliminate safety hazards. The middle exhaust groove is filled with concrete during pouring to form a stress-bearing shear pier, which not only improves the stress of the composite dense-ribbed floor, but also makes the concrete pouring at the bottom of the core mold more compact.
[0004] The technical solution adopted by the utility model to solve the technical problem is: a new type of composite ribbed floor assembly mold, including a plurality of hollow box bodies;
[0005] The side wall of the box body is provided with at least one exhaust groove penetrating the upper and lower surfaces.
[0006] The box body of this scheme is used to be set in the middle of a large-size rib beam floor. When in use, the two box bodies are brought close to each other to form a combined mold, in which the exhaust grooves are butted against each other, and concrete is poured from the outside of the two combined molds. The concrete flows from the bottom of the combined mold to the middle. Since the exhaust holes are formed in the middle part of the combined mold through the exhaust grooves after the combined mold is formed, that is, the middle part of the combined mold is connected from top to bottom, the gas under the combined mold can be discharged smoothly during the flow of concrete to the middle, and the concrete can more easily fill the lower side of the box body, which can effectively avoid the formation of voids.
[0007] Preferably, the two boxes are arranged adjacent to each other, wherein the notches of the exhaust grooves are oppositely butted, that is, the two boxes are a group, and the two exhaust grooves can be closed to form a larger exhaust hole.
[0008] Preferably, the side wall of the box body is provided with a cantilevered edge around the outside. The cantilevered edge can isolate the box body from the steel bar, prevent the outer wall of the box body from directly contacting the steel bar, and allow the concrete to wrap the steel bar smoothly, which not only ensures the protective layer of the steel bar but also effectively prevents the box from swinging left and right when pouring concrete, thereby ensuring the molding quality.
[0009] Preferably, the inner wall of the box body is provided with a plurality of reinforcing ribs, so as to improve the strength of the box body.
[0010] Preferably, connecting pieces are provided between adjacent box bodies, through which the relative positions of the box bodies can be locked to prevent the combined mold from moving relative to each other during pouring.
[0011] Preferably, the exhaust groove is an arc groove or a prism groove, so that after the adjacent boxes are brought together, the exhaust grooves can be smoothly combined to form exhaust holes.
[0012] Preferably, the exhaust groove is thick at both ends and thin in the middle, so as to make the shear pier formed by the exhaust groove more stable.
[0013] Preferably, the two ends of the exhaust groove transition smoothly to the middle, which can make the shear pier formed by the exhaust groove more stable.
[0014] Beneficial effects of the utility model:
[0015] The combined mold used in this solution can make the volume of a single box smaller while meeting the same evacuation rate, reduce the difficulty of box processing, and when pouring concrete, the air can be exhausted smoothly from the bottom of the combined mold to ensure that the concrete is poured densely, eliminating safety hazards. The combined mold makes the ribbed beam floor evacuation rate higher, reduces the amount, reduces the deadweight of the floor, and is economical. The concrete poured in the exhaust holes can reserve enough line crossing and junction box installation space for strong and weak electricity installation. When pouring, the middle exhaust slot is filled with concrete to form a shear pier, which not only improves the stress of the composite dense ribbed floor, but also makes the concrete pouring at the bottom of the core mold more dense.

[0019] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.
[0020] Example
[0021] like Figure 1 As shown, a novel composite ribbed floor assembly mold includes a plurality of hollow box bodies 1; the side wall of the box body 1 is provided with at least one exhaust groove 2 penetrating the upper and lower surfaces.
[0022] The box body 1 of this scheme is used to be arranged in the middle of a large-size rib beam floor. When in use, the two box bodies 1 are brought close to each other to form a combined mold, wherein the exhaust grooves 2 are butted against each other, and concrete is poured from the outside of the two combined molds, and the concrete flows from the bottom side of the combined mold to the middle part. Since an exhaust hole is formed in the middle part of the combined mold through the exhaust groove 2 after the combined mold is formed, that is, the middle part of the combined mold is connected from top to bottom, the gas under the combined mold can be discharged smoothly during the flow of concrete to the middle part, and the concrete can more easily fill the lower side of the box body 1, which can effectively avoid the formation of voids.
[0023] The exhaust groove 2 is used for exhaust during pouring and can be used as a load-bearing shear pier after solidification.
[0024] The two boxes 1 are arranged adjacent to each other, and the notches of the exhaust grooves 2 are oppositely butted, that is, the two boxes are a group, and the two exhaust grooves can be closed to form a larger exhaust hole.
[0025] The side wall of the box body 1 is surrounded outwardly with a cantilever edge. The cantilever edge can isolate the box body 1 from the steel bar, prevent the outer wall of the box body 1 from directly contacting the steel bar, and allow the concrete to wrap the steel bar smoothly, which not only ensures the protective layer of the steel bar but also effectively prevents the box from swinging left and right when pouring concrete, thereby ensuring the molding quality.
[0026] The inner wall of the box body 1 is provided with a plurality of reinforcing ribs, so as to improve the strength of the box body 1 .
[0027] Connectors are provided between adjacent box bodies 1. The relative positions of the box bodies 1 can be locked by the connectors to prevent the combined molds from moving relative to each other during pouring.
[0028] The exhaust groove 2 is an arc groove or a prism groove, so that after the adjacent box bodies 1 are brought close together, the exhaust grooves 2 can be smoothly combined to form an exhaust hole.
[0029] The exhaust groove 2 is thick at both ends and thin in the middle. The exhaust groove 2 has a smooth transition from both ends to the middle, which can improve the stability of the shear pier formed by the exhaust groove 2.
[0030] The combined mold used in this solution can make the volume of a single box body 1 smaller under the premise of meeting the same evacuation rate, reduce the processing difficulty of the box body 1, and when pouring concrete, the air can be exhausted smoothly from the bottom of the combined mold to ensure that the concrete is poured densely, eliminating safety hazards. The combined mold makes the ribbed beam floor slab evacuation rate greater, reduces the amount used, reduces the deadweight of the floor slab, and is economical. The concrete poured in the exhaust holes can reserve enough line crossing and junction box installation space for strong and weak electricity installation. When pouring, the middle exhaust groove is filled with concrete to form a load-bearing shear pier, which not only improves the stress of the composite dense ribbed floor slab, but also makes the concrete pouring at the bottom of the core mold more dense.
[0031] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0032] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
