Formwork Supporting Structure of Fair-faced Concrete Basement External Wall Formwork

technical field

The utility model relates to a formwork supporting structure of a building construction formwork, in particular to a formwork supporting structure of a clear-water concrete basement exterior wall.

Background technique

Most of the exterior walls of fair-faced concrete basements use large steel-frame bamboo-glue formwork as the formwork. This formwork is light in weight, high in strength, and has many turnover times. However, if the formwork is not properly supported, it may cause mold expansion. The quality of the basement external wall formwork support has a great influence on the whole building. Therefore, it is very important to deal with the problem of the large formwork support structure of the basement external wall.

The utility model is realized by adopting the following technical scheme: a formwork support structure for the exterior wall of a clear-water concrete basement, which includes combined steel formwork, square wood, steel pipes, full house scaffolding, and trusses respectively installed on the outer dimension lines at both ends of the wall body and pull bolts. It is characterized in that: the square wood is evenly installed on the outside of the combined steel formwork, and a plurality of steel pipes are evenly installed on the outside of the square wood. A plurality of sets of horizontal corrugations of steel pipes are evenly installed on the outside of the vertical corrugations of the steel pipes. Install tension bolts between two groups of steel pipe horizontal corrugations symmetrical to each other on the outer side of the combined steel formwork. The stay bolts vertically pass through the combined steel formwork, and a waterproof gasket is installed in the middle. A full house scaffolding is installed on the outer side of the horizontal corrugated steel pipe on the left side, and a plurality of diagonal braces are installed between the full house scaffolding and the ground. The truss is installed on the outside of the steel pipe horizontal corrugation on the right.

Further, the two ends of the pull bolts are fixed by nuts.

The diagonal braces are installed obliquely, the upper part of the diagonal braces is fixedly installed on the scaffolding by steel pipe fasteners, and the bottom of the diagonal braces is fixed on the ground by ground anchors.

Scissor braces are arranged inside the truss, and a plurality of supporting steel pipes are installed between the outside of the truss and the wall surface of the retaining wall.

Each set of steel pipe horizontal corrugations is composed of two steel pipes, and the two steel pipes are connected by steel pipe fasteners.

The utility model has the beneficial effects of simple structure and convenient installation; it can ensure reliable support of the formwork of the basement outer wall structure, avoid component deformation during construction, and ensure the pouring quality of the basement outer wall.

Detailed ways

As shown in Figure 1 and Figure 2, the formwork support structure of the exterior wall of the fair-faced concrete basement includes a combined steel formwork 1, square wood 2, steel pipes, full house scaffolding 8, and trusses 5 installed on the outer dimension lines at both ends of the wall. and pull bolts 6; it is characterized in that: the square wood 2 is evenly installed on the outside of the combined steel formwork 1, and is used as a formwork stiffener. A plurality of steel pipe vertical corrugations 4 are evenly installed on the outside of the square timber 2 . The outside of the steel pipe vertical flute 4 is evenly equipped with multiple groups of steel pipe horizontal flute 3, and each group of steel pipe horizontal flute 3 is composed of two steel pipes, and the two steel pipes are connected by steel pipe fasteners. Between the two groups of steel pipe horizontal corrugations 3 that are symmetrical to each other on the outside of the combined steel formwork 1, the pull bolts 6 are installed; the pull bolts 6 pass through the combined steel formwork 1 vertically, and the two ends of the pull bolts 6 are fixed by nuts , and a waterproof gasket 6.1 is installed in the middle. A full house scaffolding 8 is installed on the outer side of the steel pipe horizontal corrugated 3 on the left side, and a plurality of diagonal braces 7 are installed between the full house scaffolding 8 and the ground. 8, the bottom of the diagonal brace 7 is fixed on the ground by ground anchors 10. The truss 5 is installed on the outside of the steel pipe horizontal corrugation 3 on the right, and scissor braces are arranged inside the truss 5 , and a plurality of supporting steel pipes are installed between the outside of the truss 5 and the retaining wall. As shown in Figure 1, a waterstop 9 is installed between the ground and the basement exterior wall 11 to prevent indoor water seepage. After the steel bars of the basement exterior wall 11 are bound and accepted, the composite steel formwork 1 is connected with fasteners and installed on the outer dimension line of the basement exterior wall 11 to be constructed, and then square timber 2 is installed on the periphery of the composite steel formwork 1 in sequence. , Steel pipe vertical flute 4 and steel pipe horizontal flute 3. Square timber 2 also can be installed on the combined steel formwork 1 before the combined steel formwork 1 is installed. Steel pipe horizontal flute 3 and steel pipe vertical flute 4 are used to further support and fix the formwork. Install the pull bolt 6 again, and the pull bolt 6 passes in the middle of the two steel pipes of the steel pipe horizontal corrugated 3. Adjust the horizontal position and verticality of the formwork, and tighten the pull bolts 5 after passing the acceptance check. Then respectively install and fix the full house scaffolding 8, the diagonal braces 7 and the trusses 5. The full house scaffolding 8, the diagonal braces 7 and the trusses 5 can make the formwork support on both sides more reliable.
