Problems solved by technology

At present, the method of piercing the core bolts is to spring the wires separately on the outside of the formwork on both sides, and drill each hole with an electric pistol. The construction is cumbersome, and the normal construction cannot be carried out when the power is off, so the construction is inconvenient.
If the drilling heights and positions of the templates on both si

Embodiment Construction

[0016] A kind of wood formwork system core-through pull bolt drill of the present embodiment, such as figure 1 , figure 2 As shown, it includes a twist drill 1, a handle 2, a casing handle 3, and a bearing 4; the handle 2 has a total length of 1450 mm, and one end of the twist drill 1 is welded and installed, and the length of the twist drill 1 is 200 mm. A short steel bar 5 is welded on the inner diameter of the bearing 4, and the short steel bar 5 is welded and fixed to the handle 2; the handle 2 at a distance of 250 mm from the bearing 4 is concave, with a depth of 150 mm and a width of 200 mm; and the lowest point of the concave A casing handle 3 is fitted on the handle 2 of the handle. The twist drill bit (1), the casing handle (3), and the bearing 4 are made of reinforced materials. The handle 2 is made of a circular steel bar material with a diameter of 10-14mm.

[0017] When in use, stretch the thread on one side of the formwork, mark out the hole position, and dir...

Abstract

The invention discloses a core-through split bolt drilling machine of a wood formwork system, comprising an auger bit, a handle, a casing grip and a bearing; the total length of the handle is 1450mm, one end of the handle is provided with the auger bit, and the other end of the handle is fixedly provided with the bearing; the handle 250mm away from the bearing is concave with the depth of 150mm and the width of 200mm; and the handle at the lowest concave point is sleeved and provided with the casing grip. The core-through split bolt drilling machine of the wood formwork system has the advantages of convenient utility, quick construction, no power requirement, symmetrical and accordant drilling positions at two sides of formworks, convenient punching in the split bolt, close contact between the core-through split bolt and the formworks, fixed and firm connection and saving time and labor.

Description

technical field [0001] The invention relates to a drilling device for tie bolts through a core of a wood formwork system. Background technique [0002] In building construction, the formwork size of concrete structural beams, columns, and shear walls exceeds the specification requirements, and the formwork system needs to be fixed with core bolts. At present, the core-piercing bolts are pierced by springing the wires on the outside of the formwork on both sides, and drilling each hole with an electric pistol. The construction is cumbersome, and it cannot be constructed normally when the power is off, and the construction is inconvenient. If the drilling heights and positions of the templates on both sides are inconsistent, it is difficult for the core bolts to pass through. Even if they pass through barely, the core bolts will not be in close contact with the formwork. Among them, the template is easily deformed, causing mold expansion, affecting the appearance size, causin...
