Description

Be used for veneer fair-faced concrete wall body wood former steel back of body stupefied connecting device

Technical Field

The utility model discloses a patent application relates to veneer clear water concrete construction technical field, especially relates to a be used for stupefied connecting device of veneer clear water concrete wall wood former steel back of body.

Background

The facing clear concrete is also called decoration-free concrete, is formed by one-time casting without any external decoration, and the natural surface of the cast-in-place concrete is directly adopted as the facing after the template is removed. The requirements on appearance, construction period and construction period are strict. The influence of the environmental temperature condition in winter is more obvious in northern, especially northeast industrial areas, and the effective construction time period in the year is shorter.

According to the conventional method, the wall member concrete structures of the hydropower engineering industrial factory building are basically consistent in design style and higher in height, the wall concrete pouring needs layering operation, and the layering height is generally 1-3 m. The carpenter needs to wait that the basal plane clearance is accomplished, the reinforcing bar installation is accomplished after, begins to carry out the template installation, and the template installation is accomplished and is opened a warehouse and pour the concrete after passing the acceptance check, gets into next operation circulation during lower floor's wall body construction, and is accomplished to the project organization height until pouring. When the wood formwork is installed and constructed, a large number of small-size wood formwork assembling and transverse and longitudinal back edge reinforcing operations are required, the standard size of the wood formwork on the market at present is generally 2.44m 1.22m 15mm in length, width and thickness, and the square wood back edge or the steel back edge is adopted to be screwed and reinforced through split bolts and connected into a whole. The construction is influenced by the requirements of operation environment conditions and procedure connection, the high-altitude construction operation is inconvenient, the width of a scaffold operation platform is small, the operation personnel is inconvenient to install and reinforce, the formwork installation can be started only after the reinforcing steel bar installation procedure is completed, the formwork assembling quality is extremely easy to influence, the bin number preparation time is long, and the requirement on the vertical transportation capacity of materials is high. The mounting quality and the mounting efficiency of the template become key factors which directly influence the appearance and the quality of the fair-faced concrete and restrict the construction progress.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the invention provides a connecting device for steel back edges of wood templates of facing fair-faced concrete walls.

The first frame unit and the second frame unit are connected through the splicing reserved tongue-and-groove to form a back ridge frame unit, the first frame unit and the second frame unit respectively comprise a plurality of transverse square steels, a first longitudinal square steel, a second longitudinal square steel and square wood, the transverse square steels are arranged inside the first frame unit and the second frame unit, the longitudinal square steels and the second longitudinal square steel are arranged at two ends of each transverse square steel respectively, and the square wood is arranged on the transverse square steel at the outermost side of the frame unit.

Preferably, the transverse square steel is connected with the square timber through bolts.
