Description

Technical Field

[0001] The invention relates to the field of prefabricated buildings, and in particular to an ALC horizontal strip board exterior wall connection structure and a construction method. Background Art

[0002] With the acceleration of the national construction industrialization process and the development of concrete prefabrication technology, more and more building walls are designed and constructed in an assembled manner. Autoclaved aerated concrete strip wall (ALC strip wall for short) is widely used in building walls for its good fire resistance, sound insulation, heat preservation and other properties and convenient construction.

[0003] The ALC horizontal strip board exterior wall in the prior art mainly adopts the connection method of hook bolt + angle steel, such as Figure 1 As shown, angle steels are arranged on both sides of the H-shaped steel structural column, and the ALC horizontal strip board outer wall is connected to the angle steels through hook bolts. This installation structure makes the hook bolts and angle steels exposed on the outside of the structural column. When the mesh plastering finishing is subsequently used for finishing construction, the adhesion between the paint, putty and the angle steel is poor, which can easily lead to cracking, peeling and rusting of the wall. The angle steels are prone to rust and cracking, and the wall flatness is relatively poor. Moreover, the angle steels need to be welded on site, and the construction speed is slow. Summary of the invention

[0004] The present invention firstly discloses an ALC horizontal strip board exterior wall connection structure. A channel steel is pre-fixed on a steel structure column in a factory. After the installation of the ALC horizontal strip board exterior wall is completed on site, the channel steel can be hidden in a gap between the steel structure column and the ALC horizontal strip board exterior wall to avoid rust and cracking.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is: An ALC horizontal strip board exterior wall connection structure comprises a steel structure column, a channel steel, a hook bolt, an angle steel supporting component and an ALC horizontal strip board exterior wall, wherein the channel steel is welded on one side of the steel structure column, the outer end surface of the channel steel does not exceed the outer end surface of the steel structure column, the ALC horizontal strip board exterior wall is located on the side of the steel structure column where the channel steel is provided, the channel steel is located between the steel structure column and the ALC horizontal strip board exterior wall, the ALC horizontal strip board exterior wall is fixedly connected to the steel structure column through the angle steel supporting component, a rubber gasket is filled in the gap between the channel steel and the ALC horizontal strip board exterior wall, and the ALC horizontal strip board exterior wall is fixedly connected to the channel steel through the hook bolt.

[0006] Furthermore, a channel steel is welded to each of the two ends on the same surface of the steel structure column, and the opening ends of the two channel steels are opposite to each other and both face the side away from the steel structure column.

[0007] Furthermore, the channel steel adopts C40 model.

[0008] Furthermore, the angle steel supporting member is arranged near the end of the outer wall of the ALC horizontal strip plate.

[0009] Furthermore, the cross-section of the steel structure column is rectangular.

[0010] The present invention also discloses a construction method of the above-mentioned ALC horizontal strip board exterior wall connection structure, comprising the following steps: Step 1: Pre-weld the channel steel on the steel structure column in the factory; Step 2: Complete the installation of structural beams, steel columns and floor slabs at the construction site, and then lay out the lines to determine the installation position of the ALC horizontal strip board exterior wall; Step 3: According to the installation position of the ALC horizontal strip board exterior wall, weld the angle steel support piece on one side of the channel steel on the steel structure column, and then place the ALC horizontal strip board exterior wall on the angle steel support piece; Step 4: According to the size of the gap between the ALC horizontal strip board exterior wall and the channel steel, select a rubber gasket with a thickness that matches the size of the gap and fill it into the gap between the channel steel and the ALC horizontal strip board exterior wall; Step 5: Insert the hook bolt along the thickness direction of the ALC horizontal strip board outer wall, so that the hook head of the hook bolt extends from the open end of the channel steel into the interior of the channel steel, tighten the hook bolt, and then spot weld the hook head to the channel steel; Step 6: Level the exterior walls of the ALC horizontal strips that are spliced ​​together, and then construct the finishing layer.

[0011] The present invention welds the channel steel to the steel structure column in advance in the factory, which reduces the welding work on the construction site and can improve the on-site assembly speed. The welding in the factory can also ensure that the welding accuracy is better than on-site welding. The present invention replaces the angle steels that are arranged on both sides of the steel structure column and extend to the outside in the prior art with channel steels welded to the left and right ends of the steel structure column, so that the channel steel does not extend outward to the outside of the steel structure column, reducing the transportation difficulties caused by the extension of the components. The present invention installs the ALC horizontal strip board exterior wall on the outside of the channel steel, so that the channel steel can be hidden between the steel structure column and the ALC horizontal strip board exterior wall, avoiding exposure of the channel steel, and reducing the occurrence of wall cracking and channel steel rusting during subsequent finishing and decoration. The channel steel arranged in the present invention can make the ALC horizontal strip board exterior wall lean against the channel steel during installation, which is more convenient for construction and assembly and improves construction safety. The gap between the channel steel and the ALC horizontal strip board exterior wall is filled with a rubber gasket, which can play a role of limiting and adjusting, so that the installation accuracy of the ALC horizontal strip board exterior wall is higher and the surface of the exterior wall after installation is smoother.

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0015] This embodiment discloses an ALC horizontal strip board exterior wall connection structure, such as Figure 2 As shown, it mainly includes a steel structure column 1 with a rectangular cross section, a C-shaped channel steel 4, a hook bolt 3, an angle steel support 6 and an ALC horizontal strip board exterior wall 2. According to the installation position of the ALC horizontal strip board exterior wall 2 on the steel structure column 1, a channel steel 4 is welded on the corresponding installation surface of the steel structure column 1 in advance. In this embodiment, a C40 channel steel 4 is used. A channel steel 4 is welded at each end of the installation surface of the steel structure column 1 near the edge. The open end of the channel steel 4 at each end faces outward, and the end faces of the open ends of the channel steel 4 at both ends do not exceed the end face of the steel structure column 1, so as to prevent the channel steel 4 from extending to the outside. An angle steel support 6 is welded to the mounting surface on the same side of the steel structure column 1 (i.e., the side where the channel steel 4 is provided), and the ALC horizontal strip board exterior wall 2 is placed on the angle steel support 6. The ALC horizontal strip board exterior wall 2 transmits the vertical force to the steel structure column 1 through the angle steel support 6, so that the channel steel 4 is located in the gap between the steel structure column 1 and the ALC horizontal strip board exterior wall 2, and the rubber gasket 5 is filled in the gap between the channel steel 4 and the ALC horizontal strip board exterior wall 2, and the hook head bolt 3 is inserted into the ALC horizontal strip board exterior wall 2, so that the hook head of the hook head bolt 3 extends from the open end of the channel steel 4 into the interior thereof, and the hook head of the hook head bolt 3 is fixed to the channel steel 4 by spot welding.

[0016] The construction method of the above-mentioned ALC horizontal strip board external wall connection structure is carried out according to the following steps: Step 1: Pre-weld a channel steel 4 at both ends of the same surface of the steel structure column 1 in the factory, with the open ends of the channel steels 4 facing outwards; Step 2: First, complete the construction of the main structure at the construction site, such as the construction of structural beams, steel columns and floor slabs, and then lay out the lines to determine the installation position of the ALC horizontal strip board exterior wall 2; Step 3: According to the layout position of the ALC horizontal strip board exterior wall 2, determine the welding position of the angle steel support member 6 on the steel structure column 1, and then weld the angle steel support member 6 on the steel structure column 1 at the determined position. After welding the angle steel support member 6, place the ALC horizontal strip board exterior wall 2 on the angle steel support member 6. The angle steel support member 6 is usually located at the edge where the ALC horizontal strip board exterior wall 2 is spliced ​​with each other; Step 4: After the ALC horizontal strip board exterior wall 2 is placed, according to the distance between the ALC horizontal strip board exterior wall 2 and the channel steel 4, a rubber gasket 5 with a thickness matching the distance is selected, and the rubber gasket 5 is filled into the gap between the channel steel 4 and the ALC horizontal strip board exterior wall 2; Step 5: After completing step 4, insert the hook bolt 3 along the thickness direction of the ALC horizontal strip board outer wall 2, and let the hook head of the hook bolt 3 extend out of the ALC horizontal strip board outer wall 2, so that the hook head of the hook bolt 3 extends into the inside of the channel steel 4 from the open end of the channel steel 4, tighten the hook bolt 3 first, and then spot weld the hook head to the channel steel 4; Step 6: Use special tools to adjust the ALC horizontal strip board exterior wall 2 to be flush, make the surfaces of the ALC horizontal strip board exterior walls 2 that are spliced ​​to each other flush, process the joints, and finally construct the finishing layer on the entire wall.
