Detailed Description
The drawings in the embodiments of the present invention will be combined; the technical scheme in the embodiment of the utility model is clearly and completely described; obviously; the described embodiments are only some of the embodiments of the present invention; rather than all embodiments. Based on the embodiment of the utility model; all other embodiments obtained by a person skilled in the art without making any inventive step; all belong to the protection scope of the utility model.
As shown in fig. 1-5, the utility model provides an articulated concrete pipe culvert template, which comprises a plurality of template bodies and supporting frames which are arranged side by side;
the template body includes that the polylith splices into template basis 1 of circular barrel, and template basis 1 is square plate body structure, every the horizontal both sides of template basis 1 all are equipped with a plurality of sleeve pipes 11 along length direction, and the interval with adjacent sleeve pipe 11 equals the length that the opposite side corresponds sleeve pipe 11, and both sides sleeve pipe 11 arranges in turn to can be through the block of sleeve pipe 11 each other between adjacent template basis 1, be equipped with the articulated shaft 12 of matcing along the axial in the sleeve pipe 11 of each side, thereby realize the connection of adjacent template basis 1.
Preferably, an arc-shaped groove 13 matched with the shape of the sleeve is formed in the joint of the template foundation 1 and the sleeve, and one half of the sleeve is arranged in the groove, so that seamless connection of adjacent template foundations is realized. Further, the diameter of the sleeve 11 is equal to the thickness of the formwork foundation 1, so that the flatness of the formwork foundation 1 is maintained, and concrete pouring is facilitated.
Preferably, the upper end of the formwork foundation 1 is covered with the rubber sheet 2, the length of the rubber sheet 2 is equal to that of the formwork foundation 1, and the width of the rubber sheet 2 is larger than that of the formwork foundation 1, so that concrete is directly poured on the rubber sheet 2 when a formwork is poured, the assembled rubber sheet covers the rubber sheet layer by layer, and the soft rubber sheet 2 can enable the concrete to be tightly attached to the formwork foundation 1 at the position of the sleeve 11 under the pressure of the concrete, so that the slurry leakage prevention effect is achieved.
Preferably, one end of the rubber sheet 2 is riveted with one side of the sleeve of the formwork foundation 1, and the other end extends to the next formwork body along the width direction.
The support frame includes the annular support 3 with the contact of template body medial surface and establishes triangle-shaped support 4 in annular support 3, triangle-shaped support 4 is used for supporting annular support 3.
Preferably, the annular support 3 is formed by splicing three circular grooves 31, and the abutting surfaces of adjacent circular grooves are vertically arranged so as to be convenient for disassembly after pouring is finished; the triangular support 4 is an equilateral triangle, and three sides of the triangle are movably connected in a hinged mode and the like; the bottom edge of the triangle can be movably connected and detached, so that the triangle bracket can be fixed in shape or disassembled; preferably, the bottom edge of the triangle is composed of two movably connected segments 41, connecting pieces are arranged at the contact positions of the two segments, pin holes 42 are arranged at the corresponding positions of the connecting pieces, and pins are arranged in the pin holes 42.
The working principle is as follows:
after the annular supports are spliced, the triangular supports 4 are placed in the annular supports, bolts are arranged on the bottom sides of the triangular supports 4 to support the annular supports for shape fixing, the annular supports are placed in the cylindrical template body, and concrete pouring is performed after the annular supports are placed in the pipe culvert foundation pit. The rubber sheets 2 are tightly overlapped under the action of concrete pressure, so that cement paste is prevented from leaking into the formwork body. After the concrete is cooled, the pin of the triangular bracket 4 is pulled out, the triangular bracket 4 is disassembled, the annular bracket 3 is also disassembled, and the barrel-shaped template body is completely spliced.
Example 1
In the embodiment, the length of the template foundation is 2m, the width is 17cm, and the thickness is 2 cm; the diameter of the sleeve is 2cm, and the diameter of the articulated shaft is 1 cm; this allows the width of the two formwork bases to be adjusted between 34cm and 35cm after joining. Taking a pipe culvert template with the outer diameter of 60cm as an example: when the width of the template foundation is 17cm, the width of the template foundation is required to be larger than 11 template foundations to form a barrel-shaped structure with the outer diameter of 60cm, and when the distance between the two template foundations is adjusted to be 17.5cm, the template foundation is required to be close to 11 template foundations, so that the 11 template foundations can be used to form a cylindrical structure with the outer diameter of 60cm by adjusting the distance between the template foundations.
The embodiments of the present invention have been described in detail, but the above description is only for the preferred embodiments of the present invention, and should not be construed as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
