Description

Technical Field

[0001] The utility model relates to the technical field of building reinforcement and reconstruction and prefabricated buildings, and in particular to a connection structure used for changing a masonry structure wooden floor slab into a concrete floor slab. Background Art

[0002] With the changes in urban buildings and land, some areas that are incompatible with modern urban development need to be renovated in a necessary and planned manner. For buildings that have reached the end of their service life (50 years of service life), demolition or reinforcement is usually used to extend the subsequent service life of the building. The land value of some buildings is still relatively high. After demolition and reconstruction, they cannot be rebuilt due to the constraints of urban road retreat. Therefore, reinforcement and reconstruction are usually chosen for urban renewal;

[0003] Old houses usually have problems such as unclear structural systems, lack of ring beams and structural columns in masonry structures, prefabricated floor slabs, and chaotic node connections between steel frame structures and concrete frame structures. A large number of old houses have masonry structures and wooden floor slabs + prefabricated floor slabs, which have poor integrity. Currently, there is no effective way to reinforce the buildings.

[0004] Therefore, the utility model provides a connection structure for converting a wooden floor slab into a concrete floor slab, which is used for converting a wooden floor slab of a masonry structure into a concrete floor slab. Utility Model Content

[0005] The purpose of the utility model is to provide a connection structure for replacing a wooden floor slab of a masonry structure with a concrete floor slab. Through an implementable design method for replacing a wooden floor slab of a masonry structure with a concrete floor slab, the utility model has a high assembly rate, reduces dust and noise pollution on the construction site, effectively shortens the construction period, and improves the integrity of the masonry structure and the seismic resistance of the building.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A connection structure for changing a masonry structure wooden floor slab into a concrete floor slab, comprising a masonry structure wall, a newly added floor slab arranged on the top of the masonry structure wall, and a light channel steel arranged on the masonry structure wall and cooperating with the masonry structure wall to support the newly added floor slab;

[0008] The upper part of the masonry structure wall is penetrated by a through-pull rod with a reserved hole, and the light channel steel is fixed to the masonry structure wall by a through-screw that penetrates the reserved hole, and the end of the through-screw is locked by a nut;

[0009] The newly added floor slab is supported by light channel steel and is arranged on the top of the masonry structure wall and is locked and fixed to the masonry structure wall through the floor slab reinforcement steel bars. Inorganic concrete material is poured into the gap formed by removing the wooden floor slab between the newly added floor slab and the masonry structure wall.

[0010] Furthermore, the through screw passes through the reserved hole and sealant is poured between the through screw and the reserved hole. The sealant is used to seal the connection between the through screw and the masonry structure wall, while maintaining the firmness of the connection between the through screw and the masonry structure wall, thereby preventing the through screw from shaking.

[0011] Furthermore, pressure glue is poured between the light channel steel and the newly added floor slab. The light channel steel is attached to the masonry structure wall and cooperates with the pressure glue to form a steel ring beam supporting the newly added floor slab. The pressure glue is tightened between the newly added floor slab and the light channel steel to maintain the stability of the light channel steel in supporting the newly added floor slab.

[0012] Furthermore, the light channel steel is arranged in a side U-shape and the outer side surface of the light channel steel is fixed to the outer side surface of the masonry structure wall. The light channel steel in a side U-shape has strong resistance to deformation stress, thereby improving the bearing capacity of the light channel steel for supporting the newly added floor slab.

[0013] Furthermore, a number of floor support secondary beams are provided below the newly added floor slab corresponding to the light channel steel, and the several floor support secondary beams are equidistantly welded or hinged to the top surface of the light channel steel, forming a support system for the newly added floor slab between the floor support secondary beams and the light channel steel, thereby maintaining the firmness of the newly added floor slab supported on the masonry structure wall in conjunction with the modified support.

[0014] Furthermore, the newly added floor slab is made of a composite floor slab, a truss floor slab or a cast-in-place floor slab.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The connection structure used for changing a masonry structure wooden floor slab to a concrete floor slab is to set a light channel steel on the masonry structure wall of the old house, and support the newly added floor slab through the light channel steel, thereby achieving the effect of supporting the newly added floor slab through the steel ring beam formed by the light channel steel. After the newly added floor slab is supported by the masonry structure wall, the old wooden floor slab on the masonry structure wall is removed, and the gap formed after the removal of the old wooden floor slab is filled with inorganic concrete material to form a load-bearing component of a single floor slab with the newly added floor slab, which can effectively improve the on-site assembly rate of prefabricated buildings, improve the construction environment of the building site, and realize the industrialization of prefabricated components of prefabricated buildings. At the same time, due to the use of inorganic grouting material to cast the nodes, the maintenance time of the concrete column is greatly shortened, thereby improving the earthquake resistance of the nodes and strengthening the integrity;

[0017] The steel ring beam formed by light channel steel replaces the traditional cast-in-place ring beam, which reduces the wet construction process to a certain extent and improves the efficiency of transforming wooden floors into concrete floors. BRIEF DESCRIPTION OF THE DRAWINGS
