Through-wall bolt for novel building

Abstract

The invention discloses a through-wall bolt for a novel building. The through-wall bolt mainly comprises a cone bolt (1), a taper connector (2) and an external connecting screw rod (3); external threaded joints (5) are arranged at the two ends of the cone bolt (1), and internal threads (6) are arranged in the inner circumference of the taper connector (2); the cone bolt (1) and one internal thread(6) at the small end of the taper connector (2) are correspondingly screwed tightly through the external threaded joints (5) at the two ends of the cone bolt (1); and the external connecting screw rod (3) is screwed in the internal thread (6) at the large end of the taper connector (2) through a formwork fastening thread (7-1) at one end of the external connecting screw rod (3). According to thethrough-wall bolt for the novel building, using of a plastic pipe and a specific support is completed omitted, the construction cost is greatly saved, more environmental protection is achieved, and meanwhile, the time for cutting the plastic pipe, placing the plastic pipe, placing the specific support and removing the plastic pipe of workers is significantly saved, so that construction becomes more convenient and efficient; and all parts can be easily detached to achieve the purpose of reusing and cost saving.

Description

technical field [0001] The invention relates to the technical field of building supplies, in particular to a novel building wall-through bolt. Background technique [0002] The wall-through bolt is a kind of fastener commonly used in building construction to fix the wall. However, in the actual operation of the traditional wall-through bolt, in order to reuse the bolt, a plastic tube needs to be placed on the circumference of the bolt to facilitate disassembly. Take out after mold. When the bolt is fixing the wall, it is necessary to place specific supports consistent with the size of the wall near the bolt to ensure the structural size of the wall, such as Image 6 As shown, it is a schematic diagram of traditional building bolt construction. The outer circumference of the ordinary bolt (8) is covered with a plastic sleeve (9), and a specific support (10) consistent with the size of the wall is placed near the ordinary bolt (8). In this way, workers will have a lot of wast...

Problems solved by technology

In this way, workers will have a lot of loss and waste and a long cutting time when cutting the long plastic casing into the casing of the required size, and there will be inevitable damage during use, resulting in further waste

[0003] Furthermore, workers need to spend a lot of time in the process of setting up the formwork to place specific supports in a relatively horizontal position to ensure the size of the wall. At the same time, the supports also have unavoidable wear and tear during handling and use, such as breakage, etc.

[0004] After the concrete pouring is completed, the plastic pipes protruding from the wall will take a lot of time to remove, so that the wall can be painted in the future, and a large amount of construction waste will also be generated

[0005] In addition, engineering construction units will choose cheap plastic pipes with thinner plastic pipe walls in order to save costs and facilitate the removal of plastic pipes. This plastic pipe will often be squeezed with steel bars when it penetrates the formwork, causing the plastic pipe to rupture. When the plastic pipe is in contact with the concrete high-frequency vibrating rod, the plastic pipe will also rupture. After the plastic pipe penetrates into the wall, the rupture will cause the full-length screw (traditional bolt) to directly contact the concrete, so that the screw cannot be taken out during the later demolition process, resulting in Waste and Difficulty in Formwork Removal
