Description

Technical Field

[0001] The utility model relates to the field of building templates, in particular to a chiseling-free cup-shaped foundation inner core template. Background Art

[0002] The cup-mouth foundation, also known as the cup-shaped foundation or high cup-mouth foundation, is a form of independent foundation, especially common when the upper structure of the building adopts a frame structure, a single-layer rack or a portal structure to bear the load. This foundation is usually a square or rectangular separate foundation, which is particularly suitable for the scenario of the foundation under the column. When the column is a prefabricated component, the foundation will be designed into a cup-mouth shape, and then the column is inserted and firmly embedded in the cup-mouth. This design not only ensures the stability of the structure, but also facilitates construction. In engineering practice, the application of cup-mouth foundations is quite extensive.

[0003] After the pouring of the cup-mouth foundation is completed, the inner wall of the cup-mouth foundation needs to be chiseled to increase the roughness of the inner surface. When the steel column is installed inside and cast and fixed, the firmness of the bonding between the secondary pouring concrete can be improved, and the construction quality of the steel column foundation can be improved. However, the uniformity of chiseling in this manual chiseling operation is difficult to control, the quality of chiseling construction is uneven, and it consumes a lot of manpower and has low efficiency, which will delay the construction period and needs to be improved.

[0021] Example 1, see the attached specification Figure 1-3 A chiseling-free cup-shaped basic inner core template comprises two side plates 11, two side plates 12 and a chiseling-free coating layer 14. The size of the side plates 11 is larger than that of the side plates 12. The two side plates 11 and the two side plates 12 are symmetrically arranged and connected to each other to form an inner core template 01 with a cup-shaped cross section. A bottom plate 13 is provided on the bottom surface of the inner core template 01. The bottom plate 13 is inserted into the lower port of the inner core template 01. The bottom surface and outer side surface of the inner core template 01 are covered with a chiseling-free coating layer 14. Chisel the covering layer 14 to ensure that the chisel-free covering layer 14 is tightly fitted with the inner core template 01. The chisel-free covering layer 14 is made of flexible plastic material. A number of raised blocks 141 are evenly and densely arranged on the outer side of the chisel-free covering layer 14. The raised blocks 141 are right-angled triangle structures. The short right-angled sides of the raised blocks 141 are perpendicular to the surface of the chisel-free covering layer 14. The raised block 141 structure is used to form irregular pits, which is conducive to a more complete combination of new and old concrete.

[0022] In this embodiment, the side plate A 11 is an isosceles trapezoid with a thickness of 15 mm, and the upper base, lower base and height dimensions are 922 mm×872 mm×2150 mm. The side plate B 12 is an isosceles trapezoid with a thickness of 15 mm, and the upper base, lower base and height dimensions are 590 mm×540 mm×2150 mm. The bottom plate 13 is a square plate with a thickness of 15 mm and a length and width dimension of 922 mm×562 mm.

[0023] The chiseling-free covering layer 14 of this embodiment is coated on the outer side of the inner core template 01 by gluing or nailing, thereby ensuring the firmness of the chiseling-free covering layer 14 on the outer side of the inner core template 01 and avoiding displacement and slippage.

[0024] A square wood 18 is provided adjacent to the inner sides of the side panels A 11 and B 12. The square wood 18 has a specification of 40x80mm and a length of 2200mm. The side panels A 11 and B 12 are nailed together by the square wood 18 to achieve a fixed connection.

[0025] When the inner core template 01 of this embodiment is in use, the inner core template 01 is inserted into the outer template so that the centers of the two correspond, and then the two are firmly fixed by tension bolts, and concrete is poured into the cavity between the two. After pouring is completed, the raised blocks 141 on the outer side of the chiseling-free coating layer 14 can be embedded in the concrete. After the piles are cast and hardened, the inner core template 01 and the chiseling-free coating layer 14 are removed to form dense small pits on the inner side of the cup-mouth foundation, which replaces the traditional chiseling operation process, simplifies the construction process, and solves the problem of difficult control of the uniformity of the chiseling operation.

[0026] Example 2, see the attached specification Figure 4-6 This embodiment is basically the same as the first embodiment, except that two rows of circular bolt holes 15 are provided on the surface of the side plate A 11 along its length direction, and the surface of the chisel-free coating layer 14 is correspondingly provided with circular bolt holes 15. A row of circular bolt holes 15 are provided on the middle part of the side plate B 12 along its length direction, and the surface of the chisel-free coating layer 14 is correspondingly provided with circular bolt holes 15. The diameter of the circular bolt holes 15 is 16 mm. The circular bolt holes 15 are used to fix the outer template with tension bolts to prevent the template from tilting and deviating during the pouring process, which is more conducive to the forming of the cup-shaped concrete, thereby increasing the pouring amount.

[0027] A relatively large square air hole 16 is provided in the middle of the bottom plate 13, and a corresponding square air hole 16 is provided on the surface of the chiseling-free covering layer 14. The size of the square air hole 16 is 50mm x 100mm. A steel mesh 17 covering the square air hole 16 is provided in the middle of the inner surface of the bottom plate 13. The gas in the concrete at the bottom of the formwork is discharged through the square air hole 16. The amount of gas generated at the bottom is large, so a relatively large square air hole 16 is used to exhaust the gas, and the steel mesh 17 is provided to prevent concrete leakage.
