Description

Technical Field

[0001] The present invention relates to the field of prefabricated buildings, and in particular to a sub-compartment construction structure for bottom nodes of prefabricated frame columns. Background Art

[0002] During the construction of prefabricated frame structures, there is a 20mm gap between the prefabricated frame columns and the structural layer, which needs to be filled with high-pressure grouting materials. In order to ensure that the grouting materials can be constructed normally, the frame columns are currently sealed with mortar around them to form a closed space at the bottom of the frame columns. The traditional construction method is to use mortar to touch the slope and seal the warehouse around the frame columns. This construction method is more wasteful of materials and labor. At the same time, the mortar slope needs to be removed during ground construction, and a large amount of construction waste is generated and needs to be removed.

[0003] The main reason for the above problems is that the sealing material cannot enter the assembled column and cannot be formed inside the column. In addition, the slope sealing material is not dense and is prone to leakage holes. The mortar slope is used for sealing during the construction process, which is relatively complicated and requires a large investment. Summary of the invention

[0004] The purpose of the present invention is to design a sub-compartment construction structure for the bottom node of an assembled frame column in view of the deficiencies in the prior art, so as to solve the problem that the traditional construction method wastes materials and labor and generates a large amount of construction waste.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a sub-compartment construction structure of the bottom node of an assembled frame column, which adopts the following technical scheme, including: a precast concrete column, wherein key grooves are arranged at the bottom and top of the precast concrete column, a plurality of grouting sleeves are vertically arranged inside the precast concrete column, steel bars are arranged inside the grouting sleeves, a grouting column bottom cavity is provided between the precast concrete column and the structural layer, a special sealing tool is provided in the bottom cavity of the grouting column, and the bottom of the precast concrete column is located in the special sealing tool and is filled with grouting material.

[0006] Furthermore, a plurality of bottom grouting holes are provided on the bottom side wall of the precast concrete column, and the bottom grouting holes are communicated with the grouting sleeve and the bottom cavity of the grouting column.

[0007] Furthermore, a bunker sealing material is fixed on the outer side of the bunker sealing special tool, and the outer side of the bunker sealing material is flush with the outer side of the precast concrete column.

[0008] Furthermore, the special tool for sealing the chamber includes a sealing part, the height of the sealing part is the same as the height of the cavity at the bottom of the grouting column, a bending part is provided at one end of the sealing part, a connecting part is provided at the other end of the bending part, and a gripping part is provided at the other end of the connecting part.

[0009] Furthermore, the blocking portion is parallel to the outer side of the precast concrete column and penetrates into the precast concrete column by a distance of 5 to 10 mm.

[0010] Furthermore, the height of the cavity at the bottom of the grouting column is 20 cm, and the thickness of the sealing portion is 1 to 3 mm.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The sealing material is formed inside the precast concrete column, and compared with the traditional filling mortar, less mortar is used, and less construction waste is generated;

[0013] 2. It avoids the problem of leakage holes caused by loose and loose materials in traditional slope sealing materials;

[0014] 3. Special tools for sealing warehouses can be used in a turnover manner to reduce waste;

[0015] 4. It ensures the construction quality of the prefabricated frame column nodes, saves labor and speeds up the construction progress. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1-Figure 3 As shown, during the construction of the assembled frame structure in the prior art, there is a 20mm grouting column bottom cavity 4 between the precast concrete column 1 and the structural layer, which needs to be filled with high-pressure grouting material. In order to ensure that the grouting material can be normally constructed, the precast concrete column 1 needs to be sealed with filling mortar 8 around it to form a closed space at the bottom of the precast concrete column 1; the traditional construction method is to use filling mortar 8 to touch the slope and seal the warehouse around the precast concrete column 1, which is a waste of materials and labor. At the same time, the mortar slope needs to be removed during ground construction, and a large amount of construction waste needs to be removed.
