Description

Dovetail mortise and tenon connection method between assembly parts in construction engineering

technical field

The invention relates to construction engineering, in particular to a dovetail mortise and tenon connection method between assembly parts in construction engineering.

Background technique

In the current construction engineering technology, in order to achieve a better seismic effect, the original prefabricated porous floor slab is changed to integral on-site pouring, which achieves the overall purpose of the slab, but its construction process is more complicated, mostly solid slabs, solid slabs The self-weight is very large, the heat preservation and sound insulation are poor, and the whole cast-in-place forms a steel structure with a whole layer of pouring, and the seismic cost is relatively high. If it is made into a hollow slab, its construction will be more difficult.

Wallboards and partitions are mostly built on-site. To resist earthquakes and tie steel bars, the effect is low and the labor intensity is high. There are also on-site pouring, which is costly and poor in insulation and sound insulation. There are also formed wallboards and partitions that are installed on-site. Generally, embedded parts are welded or bolted to connect, and the connection effect is poor.

The slabs in the existing construction engineering technology are usually rigidly connected by pouring on site, laying on the spot or welding. The site construction is complicated. Although the whole building is a whole, it is a rigid structure, which is easy to be damaged when encountering natural disasters such as earthquakes. Destruction, in order to resist hazards such as earthquakes, it is necessary to pay a great cost.

Contents of the invention

The purpose of the present invention is to provide a dovetail mortise and tenon connection method between assembly parts in construction engineering. The plate-shaped parts of this method can be connected into a whole without casting, welding, laying, etc., and the method is simple in construction. Easy, convenient and fast, good engineering quality, good earthquake resistance, factory production, high efficiency, low pollution, high degree of mechanization, less construction waste, saving building materials, realizing dry operation, clean construction site, construction occupies a lot of land less, reusable, and low cost.

The technical solution adopted by the present invention to solve the technical problem is: to design a dovetail mortise and tenon connection method between assembly parts in construction engineering, which is characterized in that: there are dovetail tenon joints at intervals between assembly parts in construction engineering, and adjacent A dovetail groove-shaped mortise is formed between the two mortises, and the mortise of the assembly is inserted into the mortise of the other assembly to form a dovetail mortise connection. After the mortise and the mortise are connected, if a gap is formed, it is filled by a filler; the two pieces or More than two assemblies are connected together by dovetail mortise and tenon to form an integral structure.

The mortise forms a trapezoidal structure, the long side of the trapezoid is 10-5000mm, the short side is 6-4000mm, and the height is 3-1000mm. Connection, the elastic material is any elastic material.

When the mortise needs to overcome the two degrees of freedom of the snap-in end to completely lock the two assemblies, the mortise contact surface of the two mortise and tenon connections has a protrusion on one of the mortises, and a groove on the other mortise. The protrusions and grooves of the mortise and tenon contact surfaces of the mortise and tenon joint match, and the gaps formed after the connection are filled by fillers.

When the mortise needs to overcome the directional freedom of the two snap-in ends to achieve complete locking of the two assemblies, the tenon contact surface of the two mortise and tenon connections is added with a pin hole groove at the corresponding position of the two mortise, and one of the pin holes A pin is arranged in the groove, and the pin is hinged in one of the pin hole grooves through a rotating shaft. After the mortise and tenon connection, the pin rotates around the rotating shaft and snaps into the correspondingly connected other tenon pin hole groove to realize locking.

The assembly part is any part that needs to be connected in the construction project; the material of the assembly part is any available building material.

The dovetail mortise and tenon is directly fabricated on the assembly to form an assembly with a dovetail mortise and tenon.

The mortise and mortise joints of the joints of the assembly parts are separately made into dovetail mortise and tenon joints, and the produced mortise and tenon joints are mortise and tenon joints distributed at intervals on a mortise and tenon fixing part, and mortise and tenon holes formed between two spaced mortise and tenon joints.

The beneficial effect of the present invention is that all kinds of assembly parts can be pre-manufactured in a factory, and only need to be installed on the project site without casting or welding; force, but it is not a rigid structure, so that the whole building has good seismic performance and good quality; if flexible connection is used, the internal stress of the structure generated by the earthquake is reduced, the seismic cost is reduced, and the structural seismic effect is better; the Yanwei Mao of the present invention The mortise and tenon connection method can also be separately made into a dovetail tenon tenon joint. The made tenon tenon joint can be permanently fixed on the joint of the assembly according to the needs, or it can be made into a detachable connection, which is easy to disassemble when the dovetail tenon tenon joint is not required Down.
