[0005] To solve the above technical problems, the utility model adopts the technical scheme: a pipe gallery pouring mould, which comprises a door-shaped inner die, two corner dies are hingedly connected to the lower ends of the two sides of the door-shaped inner die, and an inside bottom die is detachably connected between the two corner dies, the door-shaped inner die, the corner dies and the inside bottom die form a closed pouring inner die, and a stretching device is arranged between the door-shaped inner die and the two corner dies.

[0006] An outer pouring mould is arranged outside the pouring inner die, and the outer pouring mould comprises an outer side bottom die arranged below the inside bottom die, outer side die racks connected to the two ends of the outer side bottom die, and the outer side die racks are slidably arranged on slide rails.

[0007] Further, one end of the corner die is provided with a hinge hole connected with the door-shaped inner die, the side of the corner die facing the pouring outer mould is matched with the step shape of the pipe gallery to be poured, and the side of the corner die connected with the inside bottom die is a slope.

[0008] Further, a hoisting frame is arranged above the inside bottom die, the lower surface of the inside bottom die is a plane, the two ends of the inside bottom die are slopes matched with the end surfaces of the corner dies, and the inside bottom die and the corner dies are fixed by connecting bolts.

[0009] Further, a plurality of telescopic pipe racks are arranged between the door-shaped inner dies.

[0010] The utility model discloses a beneficial effect compared with prior art has: the angle mould and the inside bottom mould of the utility model are detachably connected, when pouring, first not according to the inside bottom mould, first pours the concrete with the angle mould bottom surface flush, then vibrates concrete, makes bubble from the inside bottom mould position and discharges, then according to the inside bottom mould, then pours the whole pipe gallery and completes.This structure can make bubble to discharge smoothly, will not gather again in the bottom platform, greatly improved the appearance quality of pipe gallery component, also saved the process of later repair, greatly improved the delivery efficiency of pipe gallery.

[0015] In the drawing, 1 is pouring inner mould, 11 is door-shaped inner mould, 12 is angle mould, 13 is inside bottom mould, 2 is pouring outer mould, 21 is outside bottom mould, 22 is outside mould frame, 3 is stretching device, 4 is telescopic pipe frame. DETAILED DESCRIPTION

[0016] As Figure 1 Shown, a pipe gallery pouring mould includes pouring inner mould 1 and pouring outer mould 2, and pouring inner mould 1 is arranged at the inside of pouring outer mould 2, and the cavity between the two is the pouring mould cavity of pipe gallery.

[0017] As Figure 2 Shown, pouring inner mould 1 includes door-shaped inner mould 11, inside bottom mould 13 and two angle moulds 12.The two sides lower ends of door-shaped inner mould 11 are hingedly connected with two angle moulds 12, and inside bottom mould 13 is detachably connected between two angle moulds 12, and door-shaped inner mould 11, angle mould 12 and inside bottom mould 13 enclose closed pouring inner mould 1, and stretching device 3 is arranged between door-shaped inner mould 11 and two angle moulds 12.Stretching device 3 can drive angle mould 12 to overturn, facilitating demoulding.Multiple telescopic pipe frames 4 are arranged between door-shaped inner mould 11, for supporting door-shaped inner mould 11.

[0018] Pouring outer mould 2 includes outside bottom mould arranged below inside bottom mould 13, and the two ends of outside bottom mould are connected with outside mould frame 22, and outside mould frame 22 is slidably arranged on slide rail.The structure of outside mould frame 22 is similar to the prior art, so the specific structure is not repeated.

[0019] The use process of the pipe gallery pouring mold is as follows: after the pouring inner mold 1 and the pouring outer mold 2 outside the inner side bottom mold 13 structure are installed in place, pouring of concrete is started, the concrete is poured to the lower surface of the corner mold 12, then the concrete is vibrated and compacted, and then 2-3 times of simple leveling and finishing are performed, each vibration position must be vibrated until the concrete at the position is compacted, that is, the concrete stops sinking, no more bubbles are generated, and the surface is flat and smooth, the structure is convenient for bubble discharge from the position of the inner side bottom mold 13. The inner side bottom mold 13 is placed after 1 hour, and then the two sides are poured.

[0020] In addition, the hinge hole connected with the door-shaped inner mold 11 is pre-set at one end of the corner mold 12, the shape of the side of the corner mold 12 facing the pouring outer mold 2 matches the step shape of the pipe gallery to be poured, and the side of the corner mold 12 connected with the inner side bottom mold 13 is a slope. The step shape of the pipe gallery to be poured is arranged on the corner mold 12, so that the molding can be completed in the first pouring, and the molding quality at the step is ensured, and secondary repair is not needed.

[0021] The hoisting frame is arranged above the inner side bottom mold 13, the lower surface of the inner side bottom mold 13 is a plane, the two ends of the inner side bottom mold 13 are slopes matched with the end surfaces of the corner mold 12, and the inner side bottom mold 13 and the corner mold 12 are fixed through the connecting bolts. The hoisting frame is convenient for hoisting and demolding of the inner side bottom mold 13, and can also be used as a counterweight to make the connection between the inner side bottom mold 13 and the corner mold 12 more firm. The slope of the corner mold 12 and the inner side bottom mold 13 is matched, so that the limiting and the cooperation by the self-weight of the inner side bottom mold 13 can be completed.

[0022] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above embodiments, and various changes can be made within the knowledge range of ordinary skilled persons in the art without departing from the purpose of the utility model.
