Description

Technical Field

[0001] This utility model relates to the field of EMC prefabricated construction in building engineering, and in particular to an EMC system wall base 70mm gap reinforcement device. Background Technology

[0002] EMC generally refers to the integrated model of design, manufacturing, and construction, which emphasizes the collaboration of the entire process of design, production, and construction, and achieves modular integration, thereby effectively reducing production costs and construction cycle.

[0003] In general, during the construction of EMC systems, existing floor slab structures are mostly made of reinforced concrete, while the walls are precast hollow composite shear walls using EMC. During installation, the space at the base of the wall is limited, so bolt holes are set on the exterior wall for positioning and installation using bolts. After construction is completed, the bolt holes are sealed.

[0004] However, the existing EMC wall base support system uses formwork and screws for support. The traditional support system is difficult to construct due to the small size of the precast wall base, and there is a lot of material waste. In addition, the traditional support system will produce screw holes, which greatly increases the risk of leakage of the external wall and is prone to causing the precast wall to be misaligned and inaccurately positioned. Utility Model Content

[0005] In order to overcome the problems of complex wall base formwork and inconvenient process overlap in the current EMC system construction.

[0006] The technical solution of this utility model is as follows: an EMC system wall base 70mm gap reinforcement device, including a concrete floor slab, an EMC precast hollow composite shear wall, angle iron fixing bolts, embedded bolts, and a template. EMC precast hollow composite shear walls are installed on both the upper and lower sides of the concrete floor slab. Angle iron fixing bolts and embedded bolts are respectively installed on the upper side of the concrete floor slab. Angle iron pieces are installed between the lower end of the EMC precast hollow composite shear wall and the concrete floor slab. The lower end of the angle iron pieces is connected to the concrete floor slab by angle iron fixing bolts. A template is installed on the outer side of the EMC precast hollow composite shear wall. A square steel pipe is installed on the outer side of the template surface, and a wooden frame is installed between the square steel pipe and the template.

[0007] Preferably, the angle iron is installed and fixed by angle iron fixing bolts, so that the angle iron fits against one side of the filling and pouring gap, while the other side of the filling and pouring gap is fixed to the formwork by pre-embedded bolts. This facilitates the pouring of concrete into the filling and pouring gap at the bottom of the wall through the wall conduit. The overall construction formwork is more convenient and faster, and it is also convenient to install and position the precast wall, thus improving convenience.

[0008] As a preferred option, the concrete floor slab is a reinforced concrete structure with a steel mesh inside, and a filling gap is provided between the lower end of the EMC precast hollow composite shear wall and the concrete floor slab.

[0009] Preferably, the angle iron fixing bolts are evenly spaced, and a connecting steel plate is welded to the lower end of the angle iron fixing bolts. The lower end of the angle iron fixing bolts extends into the interior of the concrete floor slab, and the connecting steel plate and the reinforcing mesh are welded and fixed.

[0010] As a preferred option, the embedded bolts are designed in an L-shape, with one end extending into the interior of the concrete floor slab and the embedded bolts and steel mesh being tied and fixed together. The other end of the embedded bolts extends to the outside of the EMC precast hollow composite shear wall by filling the gaps in the pouring process.

[0011] Preferably, one end of the angle iron is fitted to the EMC precast hollow composite shear wall, and the other end of the angle iron is fitted to the upper end of the concrete floor slab. Angle iron fixing nuts are installed on the threaded surface of the angle iron fixing bolts.

[0012] Preferably, the upper and lower sides of the template surface are respectively bonded to the concrete floor slab and the EMC precast hollow composite shear wall, the embedded bolts penetrate through the outside of the template, and the embedded bolts are connected to the square steel pipe, and the threads of the embedded bolts are fitted with fastening nuts.

[0013] Preferably, two wooden blocks are placed on the top and bottom sides of the template, and the height of the square steel pipe is greater than the height of the template.

[0014] The beneficial effects of this utility model are:

[0015] This EMC system wall base 70mm gap reinforcement device uses angle iron fixing bolts to install and fix angle iron parts, so that the angle iron parts fit against one side of the filling and pouring gap. The other side of the filling and pouring gap is fixed to the formwork with pre-embedded bolts. This facilitates concrete pouring at the bottom of the wall base through the wall conduit, greatly reducing the difficulty of formwork, making the positioning of the precast wall more accurate, and also reducing the wall base leakage problem of traditional formwork. It eliminates the need for secondary sealing of bolt holes, making construction simpler, faster, easier to operate, accelerating the construction progress, saving construction costs, and reducing wall misalignment and leakage problems.

A filling gap 101 is provided between the lower end of the EMC precast hollow composite shear wall 2 and the concrete floor slab 1. Angle iron fixing bolts 3 and embedded bolts 4 are respectively provided on the sides of the upper surface of the concrete floor slab 1. The lower end of the EMC precast hollow composite shear wall 2 and the concrete floor slab 1... Angle iron pieces 6 are installed in the space.

A square steel pipe 7 is installed on the outside of the template 5, and a wooden block 8 is installed between the square steel pipe 7 and the template 5. The angle iron pieces 6 are installed and fixed by angle iron fixing bolts 3, so that the angle iron pieces 6 fit against one side of the filling and pouring gap 101.

[0022] Please see Figure 1 , Figure 2 and Figure 3In this embodiment, the angle iron fixing bolts 3 are evenly spaced.

[0023] Please see Figure 1 and Figure 2 In this embodiment, the embedded bolt 4 has an L-shaped structure. One end of the embedded bolt 4 extends into the interior of the concrete floor slab 1 and is tied and fixed to the reinforcing mesh. The other end of the embedded bolt 4 extends to the outside of the EMC precast hollow composite shear wall 2 through the filling gap 101.
