Example 1
Referring to fig. 1 and fig. 2, embodiment 1 provides a structure for fixing an aluminum formwork 1 and an embedded pipe 2 in casting construction, which mainly includes the aluminum formwork 1, the embedded pipe 2 and a connecting assembly for fixing the tail end of the embedded pipe 2 on the aluminum formwork 1;
the connecting assembly comprises an adhesive seat 31, a fixed sleeve 32 and a movable sleeve 33;
the bottom of the bonding seat 31 is bonded on the aluminum template 1, the bonding seat 31 is fixedly connected with the fixing sleeve 32, an inner hole of the fixing sleeve 32 forms an assembling hole 32a and extends along the vertical direction, and the cross section of the assembling hole 32a is in an oval shape;
the number of the movable sleeves 33 corresponds to that of the fixed sleeves 32, the inner holes of the movable sleeves 33 extend in the vertical direction, the radius of the periphery of each movable sleeve 33 is consistent with the short edge of the oval of the cross section of each assembling hole 32a, the movable sleeves 33 are clamped in the corresponding assembling holes 32a, the movable sleeves 33 and the fixed sleeves 32 are fixed relatively in the vertical direction, and the embedded pipes 2 are inserted in the inner holes of the movable sleeves 33;
the movable sleeve 33 and the fixed sleeve 32 are both made of elastic materials, and the outer periphery of the movable sleeve 33 and the inner periphery of the assembly hole 32a are in mutual pressing contact, so that static friction force for making the movable sleeve 33 and the fixed sleeve 32 relatively static is generated.
Specifically, when the operator performs the construction, the operator first bonds the bonding base 31 to the unmounted aluminum mold plate 1, and at this time, the bonding base 31 and the fixing sleeve 32 fixedly connected thereto are fixedly attached to the aluminum mold plate 1.
When the bonding seat 31 is bonded or the bonding seat 31 is firmly bonded, the movable sleeve 33 is sleeved on the end part of the embedded pipe 2, and the embedded pipe 2 is installed to be assembled at a preset position. Then the aluminum template 1 is assembled, the movable sleeve 33 is clamped in the assembly hole 32a of the fixed sleeve 32, at this time, because the assembly hole 32a is an elliptical hole, and the size of the outer diameter of the movable sleeve 33 is matched with the size of the elliptical short side of the assembly hole 32a, the movable sleeve 33 can generate certain displacement in the assembly hole 32a, namely, the movable sleeve moves in the assembly hole 32a along the elliptical long side direction of the assembly hole 32a, so as to adapt to the assembly error between the embedded pipe 2 and the aluminum template 1.
Meanwhile, when the movable sleeve 33 moves in the fitting hole 32a, the fitting hole 32a is pressed, so that the movable sleeve 33 receives a reaction force which tends to move to the center of the fitting hole 32 a. This reaction force is offset by the frictional force between the outer periphery of the movable sleeve 33 and the inner periphery of the fitting hole 32a, and the movable sleeve 33 is thereby made stationary with respect to the fixed sleeve 32.
Compared with the traditional scheme of connecting the aluminum template 1 and the connecting component by using bolts or self-tapping screws, the aluminum template 1 is not processed in the embodiment 1, and the strength of the aluminum template 1 is prevented from being damaged. Meanwhile, compare in directly gluing with the gluing agent, this embodiment 1 has avoided because of receiving assembly error's influence, and the condition that the end of pre-buried pipe 2 can't normally insert in the middle of the coupling assembling hole takes place.
As a preferred embodiment, in this embodiment 1, the ratio of the long oval side to the short oval side of the cross section of the mounting hole 32a is 3:1, and the practitioner can correspondingly select the specific form of the mounting hole 32a according to his/her own requirements.
Meanwhile, in order to ensure the stability of the static friction force, in the present embodiment 1, a plurality of ring springs 34 surrounding the fitting holes 32a are embedded in the fixing sleeve 32, and the ring springs 34 apply an elastic force to the fixing sleeve 32 so that the fitting holes 32a thereof have a tendency to contract. The annular spring 34 mainly provides a radial compensation force, which can effectively increase the acting force between the inner periphery of the assembly hole 32a and the outer periphery of the movable sleeve 33, increase the friction effect, and further reduce the form requirements on the inner periphery of the assembly hole 32a and the outer periphery of the movable sleeve 33.
Referring to fig. 3, as a preferred embodiment, in this embodiment 1, a plurality of movable convex teeth 33b are formed on an outer circumference of the movable sleeve 33 and sequentially arranged along a circumferential direction thereof, a plurality of fixed convex teeth 32b are formed on an inner circumference of the assembly hole 32a, and the movable convex teeth 33b and the fixed convex teeth 32b are engaged with each other.
The fixed teeth 32b and the movable teeth 33b are engaged with each other, similar to a gear, but different from the gear, the fixed teeth 32b and the movable teeth 33b are made of elastic material. The movable sleeve 33 can be moved relative to the fixed sleeve 32 only when the static friction force is overcome and the movable teeth 33b and the fixed teeth 32b are elastically deformed and no longer engaged. This arrangement further promotes stability between the fixed sleeve 32 and the movable sleeve 33.
In addition, more specifically, in the embodiment 1, the number of the fixing sleeves 32 fixedly connected to the bonding base 31 is 1, and in another embodiment, the number of the fixing sleeves 32 fixedly connected to the bonding base 31 is 2, and the practitioner can specifically set the number according to his/her own needs.
In order to conveniently detach the fixing sleeve 32 after the aluminum formwork 1 is detached, in this embodiment 1, an inclined surface is disposed at an outer side wall of the top end of the fixing sleeve, that is, a detachment surface 32c with a certain angle is formed on the outer side wall of the top end of the fixing sleeve, so that the fixing sleeve 32 can be more conveniently detached from a poured concrete structure. Meanwhile, in this embodiment 1, the inner hole of the movable sleeve 33 is in interference fit with the embedded pipe 2, so as to fix the movable sleeve 33 and the embedded pipe 2. After the pouring is completed, the movable sleeve 33 is separated together with the aluminum formwork 1 and the fixed sleeve 32, and the movable sleeve 33 forms a concave hole with a certain depth on the poured concrete structure. This shrinkage pool can make implementation personnel carry out follow-up pipeline interface connection process comparatively conveniently.
More specifically, in the present embodiment 1, the movable sleeve 33 and the fixed sleeve 32 are fixed to each other in the vertical direction by virtue of the friction force generated by the pressing contact therebetween.
Referring to fig. 4, in embodiment 2, a groove (not shown) extending around a center line of the assembly hole 32a is further formed on an inner circumference of the assembly hole, an annular limiting tooth 4 coaxial with the movable sleeve is formed on an outer side wall of the movable sleeve 33, and the annular limiting tooth 4 is embedded in two opposite sides of the groove to limit a vertical displacement between the movable sleeve 33 and the fixed sleeve 32.
It can be understood that the groove is in the shape of an elliptical ring, and because the annular limiting teeth 4 are embedded into the two opposite sides of the groove, the whole movable sleeve 33 cannot be separated from the fixed sleeve 32, but the structure is difficult to assemble and disassemble, and the whole annular limiting teeth 4 need to be bent and deformed, or the fixed sleeve 33 can only enable the annular limiting teeth 4 to be embedded into the groove. The practitioner may also select other axial limiting structures, such as flanges, to achieve the function of fixing the movable sleeve 33 and the fixed sleeve 32 relative to each other in the vertical direction, and the description of this embodiment will not be repeated.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and those skilled in the art can make various modifications and variations. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present embodiment should be included in the protection scope of the present embodiment.
