Embodiment Construction

[0013] In order to further understand the content, features and effects of the present invention, the patent of the present invention will be further described below in conjunction with the accompanying drawings.

[0014] described as follows:

[0015] The first step: First, bind the foundation reinforcement and wall reinforcement according to the design and specification requirements.

[0016] Step 2: Formwork support on the water face, 12-15mm thick multi-layer board as the panel, 50×100 formwork and steel pipe as the skeleton, φ12 reinforcement bolts are welded to the main reinforcement of the foundation, and finally fixed with mountain-shaped pieces, the top of the formwork is higher than the foundation Concrete top surface 100mm.

[0017] Step 3: Install the mid-buried water-stop steel plate. The water-stop steel plate is placed on the epidermis of the upper reinforcement of the foundation, the bottom is spot-welded with the foundation reinforcement, and the side is fixe...

Abstract

A construction method for leaving a construction joint at the intersection of a waterproof concrete exterior wall and a foundation belongs to the technical field of construction joints in building engineering. The construction steps include that after the foundation and wall reinforcing steel bars are tied up, firstly, an upstream wall formwork is set up, an upstream formwork (1) and an upstream battens (2) are placed in sequence, and then steel pipes (3) are installed to fix the upstream formwork (1) with tension bolts (1), wherein the upstream formwork (1) is 100mm higher than the top surface of the foundation concrete; a water-stop steel plate (5) is mounted, the water-stop steel plate (5) is placed on the upper surface of the main reinforcement on the upper part of the foundation and is fixed with the steel bars (6); an inner wall face batten (7) is installed on the inner side of the wall main reinforcement, the bottom of the inner wall batten (7) is flush with the top surface of the foundation concrete, and the batten (7) is bound and fixed to the wall main reinforcement with iron wires (8). Therefore, a hanging formwork on the inner side of the outer wall is saved. The methodhas the advantages of being convenient in installation and high in construction efficiency, and ensuring the appearance quality of concrete, accelerating the construction progress and saving measurecost.

Description

technical field [0001] The invention belongs to the technical field of construction joints in construction engineering, and in particular provides a construction method for leaving construction joints at the intersection of waterproof concrete outer walls and foundations. Background technique [0002] During building construction, the construction joints between the wall and the foundation floor are mostly left at the position 300mm above the foundation floor. This method requires a 300mm high hanging formwork to be supported. The mechanical performance and stability of the hanging formwork are poor, and the appearance of the concrete at the bottom wall cannot be guaranteed. quality. Moreover, when constructing the upper wall, it is easy to cause rotten roots and skirts at the joints. Contents of the invention [0003] The purpose of the present invention is to provide a construction method for leaving construction joints at the intersection of the waterproof concrete out...
