Description

A simple tool for forming openings in cantilevered I-shaped steel structures

technical field

The utility model belongs to the field of engineering construction and particularly provides a simple tool which can be used for forming the hole of a cantilevered I-shaped steel structure.

Background technique

In the stage of high-rise building construction, it is necessary to set up a large number of cantilevered I-steel girders to support steel pipe scaffolding, and some cantilevered I-steel girders need to pass through the structural concrete wall to form openings. The traditional method of sealing around the reserved opening is to make the wall formwork at the cantilevered I-beam into a wooden box. When encountering a cantilevered layer, first pass the I-beam through the pre-embedded box, and the pre-embedded box is placed in the wall (equal to the thickness of the wall to facilitate the removal of the I-beam later). This method has the following disadvantages: 1. Traditional wooden boxes The fixing performance is poor, and it is easy to change and deviate; 2. The formed hole is easy to cause leakage without effective water-stop measures; 3. The traditional prefabricated blocking block is not packed tightly.

Utility model content

The purpose of the utility model is to provide a simple tool that can be used for forming the opening of a cantilevered I-steel structure, which is one-time input, wide in scope of application, simple in manufacture and operation, and is used to solve the problem of sealing the complex opening of a cantilevered I-steel structure. The problem of leakage caused by compactness can improve the construction quality and ensure the practical function.

The technical scheme of the utility model is: a simple tool that can be used for forming the opening of a cantilevered I-shaped steel structure, including a cuboid wooden box 1, and a wooden template 2 is provided from the upper center line to the right end of the cuboid wooden box 1, and the cuboid wooden box 1 is provided with a wooden formwork 2. A wooden template 2 is provided from the center line of the lower part of the box 1 to the left end, and a wooden support bar 3 is provided between the center line of the lower part of the cuboid wooden box 1 and the right end.

Preferably, the size of the cuboid wooden box 1 is 450mm×150mm×230mm, the size of the wooden template 2 is 225mm×150mm×15mm, and the size of the wooden support bar 3 is 50mm×15mm×20mm.

Preferably, the cuboid wooden box 1, wooden formwork 2, and wooden support bars 3 are glued together.

The utility model has the following beneficial effects:

The utility model realizes the formation of a sill in the concrete structure hole to play the role of water interception. At the same time, the mold is made through the matching prefabricated block, and the sealing block is made on site to match the hole, which can improve the cantilevered I-shaped steel structure hole to a certain extent. Acceptance rate of plugging quality. It meets the requirements of energy saving. The formwork used comes from the construction site without increasing the cost of materials. It can also be made from waste formwork to meet the requirements of material saving. Therefore, this simple tool conforms to the principle of green and environmental protection. The flexibility is strong, and the size and specifications can be determined by themselves according to the actual needs of the project, which is conducive to popularization and use.

Detailed ways

The utility model is described in detail below in conjunction with accompanying drawings and embodiments.

As shown in Figure 1-6, a simple tool that can be used for forming the opening of a cantilevered I-shaped steel structure is used for forming the opening of a cantilevered I-shaped steel structure in a wall with a wall thickness of 200mm, including a cuboid wooden box 1, a cuboid wooden box A wooden formwork 2 is provided from the upper centerline to the right end (outer wall side) of the box 1, a wooden formwork 2 is provided from the lower centerline to the left end (inner wall side) of the cuboid wooden box 1, and a wooden support is provided between the lower centerline and the right end of the cuboid wooden box 1 Bar 3; the cuboid wooden box 1, the wooden formwork 2, and the wooden support bar 3 are glued together. The size of the cuboid wooden box 1 is 450mm×150mm×230mm, the size of the wooden template 2 is 225mm×150mm×15mm, and the size of the wooden support bar 3 is 50mm×15mm×20mm.

Make a stereotyped opening limit template with a size of 300mm×300m square template, and take a hole of 260mm×180mm at the position between the midlines.

The utility model installs the I-beam through the hole, and the utility model reserves 100mm outside the inner wall 4, installs the stereotyped opening limit template 6, and uses iron nails to install the stereotyped opening limit template 6 on the inner wall 4, after the concrete pouring is completed, the utility model is dismantled to make the hole form a sill, which plays the role of water stop.

Make shaped prefabricated concrete blocking blocks, make prefabricated blocking blocks according to the size of the reserved opening, and reduce the height and width by 10mm from the original size of the opening to ensure the thickness of the caulking mortar. After the I-beam is removed, the utility model is taken out, the hole is drilled, and the prefabricated block is coated with an interface agent and filled with waterproof mortar to ensure that the gap is compact.

The size of the simple tool described in the utility model can also be adjusted according to on-site conditions, and the size in this embodiment is for reference only.
