Example 1:
referring to fig. 1, a formwork inner bracing outer tie member for pouring a shear wall is shown, and the formwork inner bracing outer tie member includes a support pipe 101, a first rubber cup 102, a second rubber cup 103, a screw 104, a first limiting member 105, and a second limiting member 106. For example, the support tube 101 may be a JDG tube. The lead screw 104 is a stainless steel rod body.
The first rubber cup 102 and the second rubber cup 103 are respectively arranged at two ends of the support tube 101, and the templates to be fixed are a first pouring template 201 and a second pouring template 202. The end surfaces of the first rubber cup 102 and the second rubber cup 103 respectively lean against the inner sides of the first casting template 201 and the second casting template 202. That is, the support tube 101 combines the first rubber cup 102 and the second rubber cup 103 to realize the inner support for the two casting templates.
Preferably, the screw 104 is disposed inside the tube body of the support tube 101, and two ends of the screw respectively penetrate through the first casting template 201 and the second casting template 202, and the first casting template 201 and the second casting template 202 are fastened by the first limiting member 105 and the second limiting member 106. That is, the two casting templates are fixed by the combination of the first limiting member 105 and the second limiting member 106 through the screw 104.
Preferably, the first rubber cup 102 and/or the second rubber cup 103 are/is provided with a double-layer sealing structure close to the end of the template, the double-layer sealing structure is respectively divided into a first sealing ring 301 and a second sealing ring 302, and the second sealing ring 302 is sleeved outside the first sealing ring 301.
Through to gluing cup 102 and/or second and gluing cup 103 and being close to in the template end and setting up to double-deck seal structure, realized the sealing of two template spare later stages concreting liquid, avoid the concrete liquid to flow from the hole body in the template.
Further, the second sealing ring 302 has a horn-shaped structure. Through setting up the second sealing ring 302 in the outside to loudspeaker column structure, promoted the compressive capacity of gluing the cup, even poured into the condition of a large amount of concrete liquid in the template under, the second sealing ring 302 of gluing the cup can not appear the condition of caving in because internal pressure is big yet to the connection between second sealing ring 302 and the template is inseparabler under the condition that pressure is big more, thereby has guaranteed the sealing performance of gluing the cup.
Furthermore, flexible cushion layers are arranged at the contact positions of the first rubber cup 102 and the second rubber cup 103 and the template. Through setting up the flexible cushion layer, mended the space that exists because the unevenness has on the template, promoted the leakproofness of gluing the cup.
Preferably, a plurality of support ribs 303 are disposed between the first sealing ring 301 and the second sealing ring 302. Further, the support ribs 303 are arranged in a diverging manner from the axis of the first seal ring. Through the structural design of each support rib 303, the structural stability of the first sealing ring 301 and the second sealing ring 302 is improved, and the situation of large deformation under the action of pressure is avoided.
Preferably, the first limiting member 105 and the second limiting member 106 are plate-shaped structures.
Further, the first limiting member 105 and the second limiting member 106 are respectively connected with the screw rod 104 through a threaded structure; and the first limiting member 105 and the second limiting member 106 are tightly attached to the outer side walls of the first casting template 201 and the second casting template 202.
That is, the first limiting member 105 and the second limiting member 106 are fixed on the screw 104, so that the outward pulling action of the first casting template 201 and the second casting template 202 is completed. And because the first limiting part 105 and the second limiting part 106 are of plate-shaped structures, the action area between the first limiting part and the template is increased, and the problem that the template is damaged due to a large pulling force in the concrete pouring process is avoided.
In the actual pouring construction process of the shear wall, after the two pouring formworks are fixed by arranging a plurality of formwork inner-support outer pull rod pieces, the shear wall can be poured. The template inner support outer pull rod piece is simple in design and quick to machine and assemble; the weight is light, the use is convenient, and the operation is simple; can simultaneously meet various use functions and has lower cost; the contact area between the rubber cup and the template is large, the support is firm, and concrete leakage can be effectively prevented; the shear wall concrete has good appearance quality.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
