Background

In the construction of building walls, the technology of supporting by using templates and then pouring concrete is mainly used. In the wall construction, the inner and outer templates can be used in large area, the template areas and positions are all of symmetrical structures, the fixation is easy, and the construction effect is good. However, in a special part of the wall body, such as a wall root, because a pre-built floor exists, an inner side formwork cannot be installed at the inner wall, and an outer side formwork lacks a corresponding fixing structure, the formwork is easy to deform, and the outer wall is uneven and not beautiful.

CN 208072956U discloses a reinforcing device for the root of a concrete shear wall, as shown in fig. 2, the template comprises two templates which are arranged correspondingly and vertically on the ground, and two U-shaped steels which are respectively arranged at the outer sides of the two templates and used for fixing the templates, wherein one side wall of the U-shaped steel is attached to the ground, the outer side surface of the concave bottom wall of the U-shaped steel is attached to the outer side surface of the corresponding template, the U-shaped steel is fixed on the ground through a plurality of reinforcing steel bars which are vertically arranged along the length direction of the U-shaped steel and penetrate through the two side walls of the U-shaped steel, the two U-shaped steels penetrate through the concave bottom walls of the two U-shaped steels and the wall penetrating screw rods of the, the two templates are parallel to each other, the distance between the two templates is the thickness of the shear wall, and sponge strips are laid between the lower ends of the templates and the ground.

The structure only solves the problem of reinforcing the shear wall 14 root template connected with the ground 15, and the scheme can not be used for the wall root of different floors.

Disclosure of Invention

The utility model discloses a solve wall body and floor intersection template and strut reinforced (rfd) problem, provide an outer wall root template fixed knot and construct.

The utility model provides a, an outer wall root template fixed knot constructs, including lower wall body, bottom plate, the pre-buried fastening screw rod of level in the bottom plate, fastening screw rod and the inside steel bar welding of bottom plate, establish the exterior sheathing in the wall body outside down, establish outer mould back of the body balk in the exterior sheathing outside, set up the inner formword above the bottom plate, the inner formword outside sets up interior mould back of the body balk, inner formword and exterior sheathing parallel arrangement set up spacing iron part between inner formword and the exterior sheathing, outer mould back of the body balk and interior mould back of the body balk between through split bolt connection fixed, outer mould back of the body balk lower extreme connect fixedly through pre-buried fastening screw rod.

The lower end of the outer template is connected with the lower wall body at a distance of 150mm, the lower end of the outer mold back balk exceeds the lower end of the outer template by 100mm, and the split bolt is arranged above the bottom plate by 200 mm.

A sponge cushion layer is arranged at the joint of the outer template and the lower wall body. Can prevent leakage and make the surface quality of the outer wall better.

Compared with the prior art, the utility model provides a fixed problem of corner template of the intersection of wall body and floor, the structure is succinct, and the practicality is strong, and the outer wall surfacing of pouring into a mould, of high quality.

In the figure: 1-wall body, 2-inner formwork, 3-limiting iron piece, 4-inner mould back balk, 5-bottom plate, 6-bottom plate internal reinforcing steel bar, 7-fastening screw, 8-lower wall body, 9-outer mould back balk, 10-bolt fixing piece, 11-split bolt, 12-sponge cushion layer, 13-outer formwork, 14-shear wall and 15-ground.

Detailed Description

As shown in fig. 1, the exterior wall root template fixing structure includes a lower wall 8, a bottom plate 5, fastening screws 7 horizontally embedded in the bottom plate 5, the fastening screws 7 are welded to internal reinforcing bars 6 of the bottom plate, an outer template 13 is arranged on the outer side of the lower wall 8, an outer template back balk 9 is arranged on the outer side of the outer template 13, an inner template 2 is arranged above the bottom plate 5, an inner template back balk 4 is arranged on the outer side of the inner template 2, the inner template 2 and the outer template 13 are arranged in parallel, a limiting iron member 3 is arranged between the inner template 2 and the outer template 13, the outer template back balk 9 and the inner template back balk 4 are fixedly connected through a split bolt 11, and the lower end of the outer template back balk 9 is fixedly connected through the embedded fastening screws 7.

Between the inner formwork 2 and the outer formwork 13 is the position of the upper wall 1. The formwork at the intersection wall corner between the upper wall 1 and the bottom plate 5 is fixed.

The connecting distance between the lower end of the outer template 13 and the lower wall body 8 is 150mm, the lower end of the outer mold back balk 9 exceeds the lower end of the outer template 13 by 100mm, and the split bolt 11 is 200mm above the bottom plate 5.

A sponge cushion layer 12 is arranged at the joint of the outer template 13 and the lower wall body 8.

The specific construction process is as follows: 1. in the installation and construction process of the external wall formwork, the external wall formwork is required to be hung downwards by 150MM according to the floor height, the external formwork back purlin is lengthened downwards by 100MM compared with the formwork, meanwhile, before the concrete of the wall body is poured, fastening bolts are pre-embedded at the upper opening of the formwork of the external shear wall, the intervals of the pre-embedded fastening bolts are arranged according to the intervals of the external wall counter-pulling screw rods and are aligned up and down, and in order to avoid the displacement phenomenon of the fastening bolts in the concrete pouring process, the pre-embedded fastening bolts are welded with the slab bottom ribs. 2. In order to enhance the tightness of the gap between the formwork and the surface joint of the concrete structure, before the upper layer outer wall formwork is installed, the outer convex part of the floor joint is removed, then a compressed sponge strip with the width of 20mm is pasted at the joint, after the concrete surface at the root of the outer wall is cleaned, the outer wall formwork is put in place, and at the moment, fastening and pre-embedding fastening bolts are fastened, so that the lower opening of the formwork can be locked, and the floor slab staggering is eliminated. And thirdly, in order to avoid the phenomena of mold explosion and mold running at the root part of the outer wall, the position of the first wall-penetrating screw rod of the outer wall is 200mm away from the surface of the concrete plate.

The construction is carried out according to the structural scheme, after the construction is carried out to two layers, the inspection is carried out, the allowable value of the joint deviation in the inspection process is 2mm, the qualified rate is found to be 98%, and the maximum value is not more than 3 mm. Completely meets the design requirements and meets the requirements of users.
