Abstract
The utility model discloses a kind of preset hole mould of concrete wall, it by side board, corner fittings, end edge plate and cross rib board group at.The corner fittings is made of outer corner fittings, bolt, interior corner fittings, washer and nut, and alternate welding two is in 45 ° of tilting bolts at the interior angle of outer corner fittings, and interior corner fittings is equipped with matched circular hole.The side board and end edge plate are wide rectangular panel blocks, 45° angle is fallen along width direction in the length end of every plate, in bevel edge, the bolt location as built in outer corner fittings presets semicircle orifice, it is connect to four angles after docking with corner fittings after side board with end edge plate angle, three blocks of spaced cross rib plates is at least connected between the side plate of two sides.The hole mould of above structure can carry position concrete gravity and concrete setting shrinkage stress in the stage of pouring, therefore greatly reduce preset cavity entrance shape and scale error, and the hole of high quality is conducive to promote engineering construction quality.
Description
Technical field
The utility model relates to a kind of construction moulds, in particular, the utility model relates to a kind of concrete wall is pre-
Set the hole mould of hole mould, especially preset gate or window.
Background technique
In architectural engineering, it is equipped with door or window at the shear wall of common concrete wall, therefore implements to want when concreting
The hole of installation door or window is reserved in predetermined position.The size and shape of reserved opening is determined by mold, in prior art condition
Lower hole mould generallys use plank production.Due to wooden rectangle hole mould limited strength, in concreting and during solidification,
Mould four wall in hole carries the gravity and shrinkage stress of concrete to some extent, these external force promote hole mould to be deformed.
Once deformation is exceeded, in addition to the damage for causing hole mould, maximum problem is after hole mould is dismantled, and engineering is not achieved in reserved opening
Design size, crooked hole necessarily affect construction quality, make hole amendment not only give up power again it is time-consuming, thus increase be built into
This.
Utility model content
Plank rectangular mold intensity difference of the utility model mainly for the prior art, the problem of non-deformability difference propose
The preset hole mould of concrete wall that a kind of structure is simple, connection is reliable, handling are easy, non-deformability is strong.
The utility model is achieved through the following technical solutions technical goal.
The preset hole mould of concrete wall, it is by side board, corner fittings, end edge plate and the rectangular frame mould of cross rib board group.It changes
It is into place sign：The corner fittings is a kind of sub-assembly, it is made of detachably outer corner fittings, bolt, interior corner fittings, washer and nut
Angular locking mechanism, outer corner fittings therein and interior corner fittings are right-angle bending plate, alternate welding two at the interior angle of outer corner fittings
Root is in 45 ° of tilting bolts, preset circular through hole at the bolt location of the corresponding outer corner fittings connection of interior corner fittings.The side board and end
Side plate is wide rectangular panel blocks, and 45° angle is fallen along width direction in the length end of every plate, in bevel edge as built in outer corner fittings bolt
Semi-circular through hole is preset in position, makees locking connection with corner fittings to four angles after docking with end edge plate angle after side board, in two sides
Three blocks of spaced cross rib plates are at least connected between side plate.
In above structure, the corner fittings is steel components, and the wall thickness of outer corner fittings therein and interior corner fittings is 3~6mm.
In above structure, the bolt specification is M10~M16mm.
The utility model compared with prior art, has the positive effect that：
1, the corner fittings is detachable member, is convenient for the assembly and disassembly of hole mould；
2, hole mould is rectangular frame mould, and quadrangle steel corner fittings makees to strengthen connection, and the connection structure is simple, using just
Prompt, cooperation is reliably；
3, in the mould connection structure of hole add corner fittings and solid matter cross rib plate, significantly increase hole mode structure intensity and just
Property, concrete gravity and shrinkage stress can be resisted in the stage of pouring, therefore greatly reduce preset cavity entrance shape and scale error, had
Conducive to promotion engineering construction quality.
Detailed description of the invention
Fig. 1 is the utility model structural upright schematic diagram.
Fig. 2 is the floor map of Fig. 1.
Fig. 3 is partial enlargement diagram at Fig. 2A, shows corner fittings in the structural schematic diagram of installation site.
Specific embodiment
Below according to attached drawing and in conjunction with the embodiments, the utility model is described in further detail.
The preset hole mould of concrete wall shown in the drawings, it is made of side board 1, corner fittings 2, end edge plate 3 and cross rib plate 4
Rectangular mold.The corner fittings 2 is the utility model for structure-reinforced component, it is a kind of steel article.As sub-assembly
Corner fittings 2 is as shown in figure 3, it forms dismountable angle by outer corner fittings 2.1, bolt 2.2, interior corner fittings 2.3, washer 2.4 and nut 2.5
To locking mechanism, outer corner fittings 2.1 and interior corner fittings 2.3 therein are that comer pieces is torn at steel plate right angle open.The present embodiment reserved opening is used for
Only fan door of stock size is disposed, therefore door specification is relatively small, outer corner fittings 2.1 and interior corner fittings 2.3 take commercially available 45 × 3 rule
The angular steel of lattice makes.In order to realize that outer corner fittings 2.1 folds assembling with interior corner fittings 2.3, the alternate weldering at the interior angle of outer corner fittings 2.1
Two are connect in 45 ° of tilting M10 bolts 2.2.In addition, at 2.2 position of bolt that the corresponding outer corner fittings 2.1 of interior corner fittings 2.3 connects
Preset circular through hole, the circular through hole are passed through for bolt 2.2.The side board 1 and end edge plate 3 are wide rectangular panel blocks, every
45° angle is fallen along width direction in the length end of plate, and in bevel edge, 2.2 position of bolt as built in outer corner fittings 2.1 is default semicircle logical
Hole, four angles use corner fittings 2 to make locking connection after side board 1 is angularly docked with end edge plate 3.In order to further enhance hole mould
Structural strength and rigidity, at least three spaced cross rib plates 4, this implementation are connected between the two sides side plate 1 of hole mould
Such as shown in attached drawing 1 or attached drawing 2, four blocks of cross rib plates 4 are connected between two sides side plate 1 between common phase.
The utility model rationally adds corner fittings 2 and spaced cross rib plate 4, the technology in the mould connection structure of hole
Measure can significantly increase the structural strength and rigidity of hole mould.In actual use, hole mould can carry institute in construction stage
Concrete gravity and concrete setting shrinkage stress in position, therefore preset cavity entrance shape and scale error are greatly reduced, it is high-quality
The hole of amount is conducive to promote engineering construction quality.
