Abstract

A stair slab formwork fixing member structure includes a fixing member, the fixing member having a first fixing surface and a second fixing surface, and a corner portion between the first fixing surface and the second fixing surface, so that the first and second fixing surfaces are not located on the same plane. Based on this, the first and second fixing surfaces of the fixing member on different surfaces are used to connect and fix a stair slab formwork between two wall panel forms, so that the stair slab formwork and the two wall panel forms in a vertical state can achieve the effect of rapid construction and dismantling, and at the same time improve the stability of the stair slab formwork construction, avoiding the concern of mold bursting and slurry overflow during the grouting operation.

Description

Staircase formwork fixing structure

This creation is about a fixed structure for building formwork, especially a stair formwork fixing structure.

According to the existing construction method of combining reinforced concrete stairs and wall panels, a grouting space is formed by building a formwork for concrete to be poured and solidified. However, the construction of the known stair formwork is to assemble a plurality of stair facade panel forms 40 in sequence between two parallel wall panel forms 50, as shown in Figures 7 and 8. The ends of the stair facade panel formwork 40 are perpendicular to the surfaces of the two wall panel formworks 50, and then the nails 60 are driven into the stair facade panel formwork 40 and then inserted into the wall panel formwork 50, thereby completing the construction of the stair formwork. However, the above construction method has many shortcomings and deficiencies, as described below:

1. Since the staircase facade panel mold 40 and the wall panel mold 50 are perpendicular to each other, the nails 60 can only be driven into the staircase facade panel mold 40 and the wall panel mold 50 in an oblique manner. Due to the limited working space, it is difficult to obtain a better force application angle, which causes inconvenience in work and affects the connection depth of the oblique insertion of the nails 60, greatly reducing the structural strength between the staircase facade panel mold 40 and the wall panel mold 50, so that it cannot withstand instantaneous pressure during grouting and is prone to mold bursting and grout seepage.

2. When removing the formwork after the grouting solidifies, since the staircase facade formwork 40 and the wall panel formwork 50 are connected and fixed by nailing, workers can only pull out the nails one by one. Since the depth of the nails 60 is limited, the formwork is easily damaged when the nails 60 are pulled out, which reduces the service life of the formwork and makes it difficult to recycle and reuse. Therefore, new formwork needs to be purchased, which greatly increases the construction cost. At the same time, it causes the felling of trees, damage to the environment and waste of resources, and lacks environmental protection benefits.

In view of this, the creator has been engaged in the manufacturing, development and design of related products for many years. Aiming at the above goals, after careful design and careful evaluation, he finally obtained this creation which is truly practical.

The technical problem that this invention aims to solve is to provide a fixing part used in stair formwork construction to address the above-mentioned deficiencies in the existing technology, especially a stair formwork fixing part structure that can be quickly assembled and disassembled, and has both formwork connection strength.

In order to achieve the above purpose, the stair slab formwork fixing member structure of the invention includes a fixing member, which has a first fixing surface and a second fixing surface, and a corner portion between the first fixing surface and the second fixing surface, so that the first and second fixing surfaces are not located on the same plane, so that a stair slab formwork is connected to two parallel wall panel formworks through the two fixing members, so as to achieve the convenience of the stair slab formwork construction and dismantling, and at the same time improve the stability of the stair slab formwork construction, and avoid the concern of mold bursting and slurry overflow during the grouting operation.

Preferably, the angle between the first and second fixing surfaces is at least 90 degrees.

Preferably, the first and second fixing surfaces are both provided with at least two through holes.

Compared with the effect of the previous technology: This invention uses the first and second fixing surfaces of the fixing member that are not on the same surface to connect and fix the stair slab formwork between the two wall panel forms, so that the stair slab formwork and the two wall panel forms that are perpendicular to each other can achieve the effect of rapid construction and dismantling, and at the same time improve the stability of the stair slab formwork construction, avoiding the concern of mold bursting and grout overflow during the grouting operation.

In addition, the first and second fixing surfaces of the fixing member are both flatly fixed to the surface of the stair formwork and the wall panel formwork, with a clear and large-area assembly state, which effectively prevents the damage of the stair formwork or the wall panel formwork during construction and use, helps to extend the service life of the formwork, thereby improving the durability of the formwork and increasing the number of repeated uses, greatly reducing the construction cost, and at the same time avoiding the felling of trees, environmental damage and waste of resources, and has environmental protection benefits.

In order to enable the review committee to have a deeper understanding and knowledge of the purpose, features and effects of this creation, please follow the [Simple Diagram Description] for details:

First, please refer to Figures 1, 2, and 3, which show a stair formwork fixing structure, including a fixing member 10, the fixing member 10 having a first fixing surface 11 and a second fixing surface 12, a corner portion 13 between the first fixing surface 11 and the second fixing surface 12, the corner portion 13 being at least 90 degrees, so that the first and second fixing surfaces 11, 12 are not located on the same plane, and the first and second fixing surfaces 11, 12 are both provided with at least two through holes 111, 121.

The use of the structure is shown in Figures 1 to 5. The fixing member 10 is used for building a building formwork, and is particularly suitable for building a stair formwork 20. The stair formwork 20 is connected to two parallel wall panel forms 30 through two fixing members 10. One of the fixing members 10 can first be flatly attached to one end surface of the stair formwork 20 with a first fixing surface 11, and then locked and fixed with bolts 14, and the second fixing surface 12 of the fixing member 10 is formed vertically with the stair formwork 20, and then the second fixing surface 12 is used to connect with one of the wall panels. The plate formwork 30 is locked and fixed, and the other end of the stair plate formwork 20 is straddled on the preset step of the other wall panel formwork 30, so that the other end of the stair plate formwork 20 and the other wall panel formwork 30 form a vertical shape. Finally, the other fixing member 10 is locked and fixed between the stair plate formwork 20 and the other wall panel formwork 30 with the first and second fixing surfaces 11 and 12 using bolts 14. Thus, the stair plate formwork 20 and the wall panel formwork 30 in a vertical shape are connected and fixed through the two fixing members 10, which greatly improves the convenience and efficiency of the stair plate formwork 20 construction.

In addition, when the fixing member 10 is fixed with the stair formwork 20 and the wall panel formwork 30 by bolts 14, it can be assembled with electric tools, which has the effect of rapid construction. After the grouting is solidified, the bolts 14 are loosened and removed from the two wall panel forms 30, and the stair formwork 20 can be easily removed, while avoiding damage to the stair formwork 20. When removing, the bolts 14 can also be removed by the reverse function of the electric tool, so as to achieve the convenience of building and dismantling the stair formwork 20, greatly reducing the manpower and time costs, and improving the working efficiency.

The structure of the above-mentioned specific embodiment can obtain the following benefits: the invention uses the first and second fixing surfaces 11 and 12 of the fixing member 10 which are not on the same surface to connect and fix the stair formwork 20 between the two wall panel forms 30, so that the stair formwork 20 and the two wall panel forms 30 which are perpendicular to each other can achieve the effect of rapid construction and dismantling, and at the same time improve the construction stability of the stair formwork 20, avoiding the concern of mold bursting and grout overflow during the grouting operation; in addition, the fixing member The first and second fixing surfaces 11 and 12 of 10 are both flatly fixed to the surface of the stair formwork 20 and the wall panel formwork 30, and have a clear and large-area assembly state, thereby effectively preventing the stair formwork 20 or the wall panel formwork 30 from being damaged during construction and use, which helps to extend the service life of the formwork, thereby improving the durability of the formwork and increasing the number of repeated uses, greatly reducing the construction cost, and at the same time avoiding the felling of trees, environmental damage and waste of resources, and having environmental benefits.

In summary, this creation has indeed achieved a breakthrough structural design, and has improved new content, while also being able to achieve industrial applicability and progress. Moreover, this creation has not been seen in any publication and is also novel, and should comply with the relevant provisions of the Patent Law. Therefore, a new patent application has been filed in accordance with the law, and the Jun Bureau Review Committee is requested to grant legal patent rights, and I am very grateful.

However, the above is only a preferred embodiment of this invention, and it cannot be used to limit the scope of implementation of this invention; that is, all equivalent changes and modifications made within the scope of this new patent application should still fall within the scope of this new patent.
