Description
Technical Field
The utility model relates to a construction field, especially a floor hole preformed die are worn to crane span structure.
Background
In engineering houses and office main buildings, each floor is provided with a distribution well, the positions of the distribution wells on each floor are uniform, a plurality of buses and cable bridges are arranged in the distribution wells, and the cable bridges are usually installed by adopting a method of installing along vertical wells because the space in the distribution wells is limited and the distribution wells are required to penetrate through floors for laying.
The existing installation method comprises the following steps: after the reserved hole die is manufactured through a bamboo plywood or a blockboard, a reserved hole matched with the support size of the cable bridge is formed through pouring, the reserved hole die is manually removed, and the bridge is fixed in the reserved hole through a bolt, and the method specifically comprises the following steps: manufacturing a wood box, reserving a hole, cleaning, installing a bridge frame, laying a cable and blocking a fire. The defects are as follows:
(1) the existing bridge frame installation method needs to manufacture a cable bridge frame mold on site before concrete pouring, and needs to decompose the mold after the concrete pouring, so that the construction efficiency is low;
(2) the existing mould needs to be decomposed after concrete is poured, so that the mould cannot be reused, and the material cost is greatly increased.
(3) The traditional construction method has many working procedures, including 5 working procedures (worker lofting, wood box manufacturing, wood box embedding, wood box dismantling and garbage cleaning), and the process is complicated and causes material waste.
Disclosure of Invention
An object of the utility model is to provide a construction convenience, but floor hole reservation mould is worn to reuse's crane span structure.
The purpose of the utility model is realized through the following technical scheme: a bridge frame through floor slab hole reservation die is a rectangular die formed by splicing a bottom plate, a coaming and a cover plate; the bottom plate is a rectangular plate, a positioning assembly for preventing displacement during pouring is arranged on the bottom plate, and the positioning assembly comprises fixing nails and fixing holes formed in the bottom plate; the coaming is provided with four coamings, the bottom edge of each coaming is respectively hinged on four side edges of the bottom plate, and the coamings can be horizontally unfolded relative to the bottom plate; a locking assembly is arranged between the adjacent coamings and comprises two bolt holes which are respectively arranged on the vertical side edges of the adjacent coamings and are distributed in a staggered manner and a fastening bolt which is arranged between the two bolt holes in a penetrating manner; the apron articulates the last border at the rear side bounding wall, and still is equipped with the handle on the right side bounding wall about and.
Compare prior art, the utility model has the advantages of:
1. detachable: the utility model comprises a bottom plate, a coaming and a cover plate; the bottom plate, the coaming and the cover plate can be assembled into a rectangular mould through the locking assembly to play the pre-embedded function of the rectangular mould; after the locking assembly is disassembled, the foldable bicycle can be horizontally unfolded, and is convenient to transport and store.
2. The cleaning is convenient: at the in-process of floor face concreting, probably have the concrete to enter into the mould in, the adhesion is on the inner wall after solidifying, the utility model discloses but the level expandes, makes things convenient for the regular clearance of mould.
3. Deviation prevention: be equipped with the fixed orifices on the bottom plate, the accessible staple is fixed it on the template, prevents the horizontal displacement that probably takes place at floor concreting in-process.
4. The leakproofness is good: the traditional pre-buried wood pattern is likely to cause large abutted seams at the periphery of the wood pattern due to uneven quality of workers, so that concrete leaks into the wood pattern; the utility model discloses each face amalgamation is inseparable, the condition that the concrete seepage entered is difficult for taking place.
5. Can be repeatedly used: the utility model discloses after floor concrete initial set, can take out the staple on the bottom plate fixed orifices, propose the mould through the handle, can continue to be used for pre-buried at next floor.
6. The construction process is simple, and the simplified installation process of the die only comprises 3 steps: firstly, lofting workers; fixing the mold; and thirdly, disassembling the die.

Description of reference numerals: the device comprises a base plate 1, fixing holes 1-1, fixing nails 1-2, a coaming 2, a cover plate 3, bolt holes 4, fastening bolts 5, a handle 6 and a rotating shaft 7.
Detailed Description
The invention is described in detail below with reference to the drawings and examples of the specification:
fig. 1 to 4 are schematic views illustrating an embodiment of a bridge through-floor hole reserving mold provided by the present invention.
A bridge frame through floor slab hole reservation die is a rectangular die formed by splicing a bottom plate 1, a coaming 2 and a cover plate 3;
the base plate 1 is a rectangular plate, a positioning assembly for preventing displacement during pouring is arranged on the base plate 1, and the positioning assembly comprises fixing nails 1-2 and fixing holes 1-1 arranged on the base plate 1;
the coaming 2 is provided with four coamings, the bottom edge of each coaming 2 is respectively hinged on four side edges of the bottom plate 1, and the coamings can be horizontally unfolded relative to the bottom plate 1;
a locking assembly is arranged between the adjacent coamings 2 and comprises two bolt holes 4 which are respectively arranged on the vertical side edges of the adjacent coamings 2 and are distributed in a staggered manner and a fastening bolt 5 which is arranged between the two bolt holes 4 in a penetrating manner;
the cover plate 3 is hinged to the upper edge of the rear side coaming 2, and a handle 6 is further arranged on the left and right side coamings 2.
The bottom plate 1, the coaming 2 and the cover plate 3 are all made of steel plates.
