Description

A form support device for horizontal convex concrete construction joints

technical field

The invention relates to an engineering device, in particular to a support device for hanging molds of horizontal convex concrete construction joints.

Background technique

During the construction of the cooling tower ring foundation 1 and the pool wall 5, a horizontal construction joint needs to be left at the bottom of the pool wall. The quality of the joint is directly related to the anti-seepage capacity of the pool root. As shown in Figure 1, steel plate waterstops cannot be used for this construction joint due to the limitation of the protective layer of the ring-based steel reinforcement. Therefore, a boss-shaped construction joint must be set at the joint to increase the water seepage path. The horizontal convex construction joints between the annular foundation of the cooling tower and the pool wall are currently adopted in the industry to weld the supporting steel bar 4 at the bottom of the vertical steel bar 3 of the pool wall (the elevation is the elevation of the upper surface of the ring base), and the formwork adopts wooden formwork strips , Utilize the welded supporting steel bar 4 to support the convex construction joint template. The construction process of this construction method is relatively complicated, and the welded full-length support steel bars are unfavorable to the waterproofing of the pool wall. There are many joints with wooden formwork, and the cross-sectional size of the convex construction joints is difficult to guarantee.

The base horizontal steel bar 2 and the vertical steel bar 3 of the pool wall are arranged at the root of the circular foundation 1 of the pool. Then it can circle the pool, and the height of the concrete boss 6 is generally 100mm.

Detailed ways

The present invention is designed with a template device that can be quickly disassembled, clamps and connecting bolts that can be adjusted in size. The template device uses a 3mm thick cold-rolled strip steel plate as the template panel, and strip hanging grooves are welded on the upper and lower sides of the template panel. , the left and right sides are connected with the fixture fixed on the edge of the vertical steel bar of the pool wall through connecting bolts, and the elevation and cross-sectional size of the construction joint formwork can be adjusted through the fixture.

In an embodiment of the present invention, as shown in FIG. 2, the horizontal convex concrete construction joint formwork support device includes a clamp 7, a connecting bolt 8, and a formwork device 9. During use, the clamp 7 is connected to the formwork through the connecting bolt 8. Device 9 is used in combination. The fixture adopts the U-shaped clamping plate 10 arranged on the edges of the left and right ends of the vertical steel bars 3 of the pool wall as shown in Figure 3. The screw rod can be used to adjust the thickness, horizontal curve, etc. of the convex concrete.

In Fig. 3, the outer side of U-shaped clamping plate 10 and the vertical steel bar 3 of the pool wall are tightly locked and fixed to be controlled by the tightening of butterfly bolt 11, adopting butterfly bolt 11 to tighten is convenient and fast, and is convenient for workers to install and disassemble. The butterfly bolt 11 passes through the outside of the fastening nut 14 and the U-shaped clamping plate 10, the outside of the U-shaped clamping plate 10 is provided with an aperture, the fastening nut 14 is placed outside the aperture, and the end of the butterfly bolt 11 is equipped with an arc-shaped clamping plate 13. It is used to compress the outer surface of the vertical reinforcement of the pool wall.
