Description

Technical Field

[0001] The utility model relates to the field of prefabricated buildings, in particular to a connection structure of a prefabricated wall and a column. Background Art

[0002] Wall panels and prefabricated columns are the basic units of prefabricated buildings. They are manufactured in factories and then transported to the areas where construction is required. They are quickly assembled to achieve the purpose of quickly building buildings.

[0003] As for the current connection between wall panels and prefabricated columns, the two are usually connected by post-poured concrete. The post-poured concrete plays a certain consolidation role, connecting the wall panels and prefabricated columns together. However, no steel bars are set between the wall panels and the prefabricated columns, which makes it easy for concrete cracks to occur between the wall panels and the prefabricated columns, posing a safety hazard.

[0004] To solve this problem, some wall panels and prefabricated columns are provided with exposed steel bars at the connection between them, and the connection between the two is achieved by welding, and then concrete is poured at the connection to achieve the connection between the wall panel and the prefabricated column. This connection method solves the problem of insufficient connection strength between the wall panel and the prefabricated column to a certain extent, but the prefabricated column is usually very long. In order to ensure sufficient connection strength, a sufficient number of steel bars need to be set on the prefabricated column, which results in a lot of time required to weld these steel bars, slowing down construction efficiency.

[0035] In order to make the technical problems to be solved, technical solutions and advantages of the present invention more clear, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0036] like Figure 1-7 As shown, an embodiment of the utility model provides a prefabricated wall and column connection structure, including a wall 1 and a column 2, wherein the wall 1 includes a first wall panel 11, a second wall panel 12 and a wall core 13, wherein the wall core 13 is arranged between the first wall panel 11 and the second wall panel 12, and is fixed between the first wall panel 11 and the second wall panel 12 in an existing manner, wherein the width of the first wall panel 11 and the second wall panel 12 is greater than the width of the wall core 13, and the wall core 13 is arranged between the first wall panel 11 and the second wall panel 12 in the width direction, so that grouting grooves 14 are formed on both sides of the wall 1. A plurality of anti-slipping public parts 15 are also arranged on the left and right sides of the first wall panel 11 and the second wall panel 12, and the anti-slipping public parts 15 are located in the grouting grooves 14.

[0037] The aforementioned column 2 comprises a column body 21 , and a plurality of anti-slip female parts 22 are arranged in the length direction of the column body 21 . The anti-slip male parts 15 and the anti-slip female parts 22 can be locked with each other.

[0038] In the present application, the anti-slip male component 15 and the anti-slip female component 22 can be locked in the grouting groove 14. When the wall 1 and the column 2 are connected, the anti-slip male component 15 and the anti-slip female component 22 are connected, and then concrete is poured in the grouting groove 14, so that the anti-slip male component 15 and the anti-slip female component 22 are consolidated by concrete in the grouting groove 14, which not only ensures the steel connection structure between the wall 1 and the column 2 and the connection strength, but also enables the concrete consolidation to further fix the connection between the anti-slip male component 15 and the anti-slip female component 22, and ensures that the connecting column between the wall 1 and the column 2 is filled with concrete with a certain supporting force.

[0039] In an embodiment of the present application, the anti - detachment male part 15 and the anti - detachment female part 22 have the same structure. Taking the anti - detachment male part 15 as an example, the anti - detachment male part 15 includes a first embedded part 151, a second embedded part 152, and a connecting part 153. The first end of the first embedded part 151 is embedded on the left and right sides of the first wall panel 11, the first end of the second embedded part 152 is embedded at the left and right ends of the second wall panel 12, and the two ends of the connecting part 153 are respectively connected to the second ends of the first embedded part 151 and the second embedded part 152. The anti - detachment male part 15 as a whole presents an inverted U - shape, and the anti - detachment male part 15 forms a rectangular space around in the grouting groove 14. Similarly, the anti - detachment female part 22 as a whole also presents an inverted U - shape, and the anti - detachment female part 22 forms a rectangular space on the column body 21.

[0040] When the wall 1 and the column 2 are assembled, the rectangular spaces formed by the anti - detachment female part 22 and the anti - detachment male part 15 partially overlap, and this overlap is located in the grouting groove 14. At this time, only an anti - detachment steel bar needs to be inserted into the overlapping area from above the grouting groove 14. Under the action of the anti - detachment steel bar, the separation between the wall 1 and the column 2 can be avoided. Preferably, the anti - detachment male part 15 and the anti - detachment female part 22 are formed by bending a steel bar.

[0041] In this embodiment, the anti - detachment male part 15 and the anti - detachment female part 22 have a simple structure and can be preset in the wall 1 and the column 2. By inserting the anti - detachment steel bar to restrict the anti - detachment male part 15 and the anti - detachment female part 22, it not only ensures the connection strength between the wall 1 and the column 2, but also does not require too much time to fix the anti - detachment male part 15 and the anti - detachment female part 22, having good connection strength and connection convenience.

[0042] In another embodiment of the present application, the anti - detachment male part 15 includes a first embedded part 151 and a second embedded part 152.

The second top ends of the first embedded part 151 and the second embedded part 152 are bent to form an acute angle α, and the bent parts formed by the first embedded part 151 and the second embedded part 152 overlap; correspondingly, the anti - detachment female part 22 includes a third embedded part 154. The first end of the third embedded part 154 is embedded in the column body 21, the second end of the third embedded part 154 is bent to form an acute - angled structure, and the bent part of the third embedded part 154 is hooked in the overlapping area of the bent parts of the first embedded part 151 and the second embedded part 152. Preferably, the anti - detachment male part 15 and the anti - detachment female part 22 are formed by bending a steel bar.

[0043] In this embodiment, the anti - detachment male part 15 and the anti - detachment female part 22 have bends. The three bends are hooked together to play a role in connecting the wall 1 and the column 2. At the same time, the three bends are hooked in the grouting groove 14, and concrete is poured into the grouting groove 14 to prevent the separation between the three bends, ensuring the connection strength between the wall 1 and the column 2.

[0044] In the third embodiment of the present application, the anti-slip male part 15 includes a first embedded part 151 embedded in the first wall panel 11 and a second embedded part 152 embedded in the second wall panel 12, and the non-embedded ends of the first embedded part 151 and the second embedded part 152 are provided with external threads.

A counter-ridge 111 is formed on the inner side of the bottom end of the first wall panel 11, and a counter-ridge groove 112 is formed on the outer side of the wall head 16. The counter-ridge 111 can be snapped into the counter-ridge groove 112. By using the counter-ridge 111 and the counter-ridge groove 112, it can be ensured that the wall 1 can be quickly and accurately positioned during vertical assembly, thereby ensuring the verticality of the wall 1.

[0049] Furthermore, the wall core 13 includes several stacked functional layers, which are made of one or more of waterproof materials, thermal insulation materials, sound insulation materials, and fireproof materials. The functional layers are bonded together using existing technology, so that the wall 1 in the present application has additional functions such as waterproofing, thermal insulation, and sound insulation.
