[0002] During the construction of reinforced concrete cover slabs, a number of reserved holes are usually made on the surface of the reinforced concrete cover slabs to facilitate the lifting and transfer of the reinforced concrete cover slabs. The construction of reinforced concrete cover slabs requires a large amount of work and requires a large number of reserved holes. In the prior art, when the concrete is initially set, the operator usually uses a small shovel to remove concrete on both sides of the lifting steel bars in the concrete to form recessed holes on both sides of the lifting steel bars. When lifting the reinforced concrete cover slabs, the hook is passed through the holes and the lifting steel bars are lifted, so that the reinforced concrete cover slabs can be lifted.

[0003] The operation of manually digging concrete to form holes on the surface of reinforced concrete cover plates is laborious and inefficient, and the dug holes have poor forming effects, are irregular, and are not uniformly beautiful. Utility Model Content

[0004] The purpose of the needle of the utility model is to provide a reinforced concrete cover plate construction forming structure. By blocking the positioning shell with the positioning piece, the concrete can be effectively prevented from flowing into the positioning shell, so that a unified positioning shell can be formed on the surface of the reinforced concrete cover plate after forming, with a regular, unified and beautiful shape, avoiding the formation of pits of different sizes on the surface of the reinforced concrete cover plate.

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1-Figure 6 As shown, the reinforced concrete cover plate construction forming structure of the utility model includes a steel frame, on which a positioning shell 10 is fixed; the positioning shell 10 is a hollow hemispherical body with an opening facing upward, and a lifting ring 11 is fixed inside the positioning shell 10; the positioning member includes a positioning block 21, and the positioning block 21 is fitted in the positioning shell 10; the bottom of the positioning block 21 is provided with an avoidance groove 22 with an opening facing downward, and the lifting ring 11 is fitted in the avoidance groove 22; the top of the positioning block 21 is provided with an avoidance block 23, and the top of the avoidance block 23 is provided with a handle 24.

[0019] In this embodiment, the steel bar frame is welded by a plurality of steel bars 31 to form a rectangular frame body, and a plurality of mutually perpendicular steel bars 31 are welded and fixed inside the rectangular frame body, so that the steel bar frame structure can be stable and reliable.

[0020] The positioning shell 10 is welded and fixed in the steel frame. Specifically, a plurality of reinforcing rods 12 are fixed to the outer wall of the positioning shell 10. The plurality of reinforcing rods 12 are respectively welded to the steel bars 31 in the steel frame, so that the positioning shell 10 can be firmly and reliably welded and fixed in the steel frame, thereby ensuring that the positioning shell 10 can be firmly and reliably cast and fixed in the concrete cover plate 30.

[0021] The hanging ring 11 can be welded and fixed in the positioning shell 10, or the hanging ring 11 can be integrally formed with the positioning shell 10, which is not specifically limited here.

[0022] like Figure 3 As shown, after casting, a positioning shell 10 with a regular and uniform shape and an opening facing upward is formed on the surface of the reinforced concrete cover plate 30 , and the reinforced concrete cover plate 30 can be hoisted through the hoisting ring 11 in the positioning shell 10 .

[0023] The positioning shell 10 is in the shape of a hollow hemisphere with an opening facing upward, and can form a reserved groove with a regular and uniform shape and an opening facing upward on the surface of the reinforced concrete cover plate 30, so that the structure of the reinforced concrete cover plate 30 is beautiful and uniform.

[0024] The top of the lifting ring 11 does not protrude from the opening of the positioning shell 10 , so that the lifting ring 11 can be prevented from protruding from the surface of the reinforced concrete cover plate 30 , thereby avoiding affecting the stacking of the reinforced concrete cover plates 30 .

[0025] The positioning shell 10 is in the shape of a hollow hemispherical body with an opening facing upward, the positioning block 21 is in the shape of a hemispherical body, and the avoidance block 23 is in the shape of a cylinder. The radius of the positioning shell 10, the radius of the positioning block 21 and the radius of the avoidance block 23 are equal.

[0026] The positioning block 21 can be completely fitted into the positioning shell 10, and can effectively seal the positioning shell 10, effectively preventing concrete from flowing into the positioning shell 10, thereby forming a positioning shell 10 with a regular and beautiful shape on the surface of the reinforced concrete cover plate 30 after molding, and can effectively prevent the lifting ring 11 from being cast and fixed in the reinforced concrete cover plate 30.

[0027] When the positioning block 21 fits into the positioning shell 10, the avoidance block 23 protrudes from the upper surface of the positioning shell 10 and the top opening of the steel frame, thereby preventing the positioning piece from being submerged in the concrete as a whole, and ensuring that the positioning piece can be taken out as a whole. In addition, even if concrete is poured around the avoidance block 23, the opening of the reserved groove will not be enlarged, and the opening of the reserved groove is still circular, and its radius is still the radius of the positioning shell 10, which can still ensure that the shape of the reserved groove on the surface of the reinforced concrete cover plate 30 is regular and uniform.

[0028] The outer surface of the positioning block 21 is provided with a non-stick layer (not shown in the figure), and the inner surface of the positioning shell 10 is provided with a non-stick layer (not shown in the figure). This can effectively prevent the concrete from sticking in the gap between the positioning block 21 and the positioning shell 10. When the positioning block 21 is taken out of the positioning shell 10, the adhesion of the concrete on the outer surface of the positioning block 21 can be effectively reduced, making it easier to take out the positioning block 21.

[0029] The outer surface of the avoidance block 23 is provided with a non-stick layer (not shown in the figure), which can effectively reduce the adhesion of concrete on the outer surface of the avoidance block 23 when the positioning block 21 is removed from the positioning shell 10, making it easier to remove the positioning block 21.

[0030] A handle 24 is provided on the top of the avoidance block 23, and the positioning piece can be easily moved and used by holding the handle 24.

[0031] The positioning block 21, the avoidance block 23 and the handle 24 can be welded together or integrally formed through a processing technique, and no specific limitation is made here.

[0032] The depth of the avoidance groove 22 is greater than the height of the lifting ring 11, and the width of the avoidance groove 22 is greater than the width of the lifting ring 11, so that the avoidance groove 22 can effectively avoid the lifting ring 11. When the positioning block 21 is placed in the positioning shell 10, the lifting ring 11 will extend into the avoidance groove 21, so as to prevent the lifting ring 11 from blocking the positioning block 21 from fitting in the positioning shell 10.

[0033] The method for casting the reinforced concrete cover plate 30 is a common method in the technical field and is not specifically limited here.

[0034] The forming groove 40 is a detachable and assembled forming groove commonly used in the art for casting reinforced concrete cover plates, and is not specifically limited here. For example, the forming groove 40 can be in the shape of a rectangular parallelepiped, and the forming groove 40 includes four groove walls, and two adjacent groove walls are connected by bolts, which can facilitate the assembly and disassembly of the forming groove 40.

[0035] When pouring the reinforced concrete cover 30, the steel frame is placed in the rectangular forming groove 40, and the positioning block 21 is placed in the positioning shell 10. The positioning shell 10 is blocked by the positioning block 21, and concrete does not enter the positioning shell 10. Concrete is poured in the forming groove 40. When the concrete is initially set, the forming groove 40 is disassembled and removed, and the positioning piece is taken out of the positioning shell 10, and then the concrete cover 30 is completely formed. The positioning shell 10 is exposed on the formed concrete cover 30, so that a reserved groove is formed on the surface of the concrete cover 30. The shape of the reserved groove is the shape of the positioning shell 10, and the reserved groove is a hollow hemispherical shape with the opening facing upward.

[0036] The reinforced concrete cover plate construction molding structure of the utility model is simple, stable, reliable and easy to use. Through the reinforced concrete cover plate construction molding structure of the utility model, regular and uniform reserved grooves can be formed on the surface of the formed reinforced concrete cover plate 30, avoiding the formation of pits of different sizes on the surface of the reinforced concrete cover plate 30.

[0037] In addition, the lifting ring 11 is fixed in the semicircular positioning shell 10, which can facilitate the insertion and extension of the lifting hook in the positioning shell 10, thereby facilitating the hanging connection of the lifting hook to the lifting ring 11.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
