Description

Technical Field

[0001] This invention relates to the field of prefabricated building construction, specifically to the construction node of openings and its prefabricated building. Background Technology

[0002] With the development of modern industrial technology, prefabricated buildings have made breakthrough progress. Due to their fast construction speed and low labor costs, they have been rapidly promoted worldwide. ALC panels, as prefabricated materials for interior and exterior walls, are lightweight, possess excellent thermal insulation, fire resistance, and sound insulation properties, are low-cost, energy-efficient, and environmentally friendly, and offer fast construction and easy installation. Currently, most exterior walls are constructed using traditional masonry structures with added structural columns and ring beams, but this method is cumbersome, inefficient, and costly.

[0003] In the existing technology, the domestic standard drawing set only has guiding nodes for window openings in the exterior wall that are less than 2.4m, but there are no guiding nodes for window openings that are greater than 2.4m, which greatly restricts the building's functional use. In the projects under construction, most of the nodes for window openings in the exterior wall that are greater than 2.4m are constructed by adding structural columns and ring beams to the traditional masonry structure exterior wall, which seriously delays the construction progress of the exterior wall.

Those skilled in the art can reasonably determine the specific meaning of the above terms in this embodiment in conjunction with the specific content of the technical solution.

[0030] Reference Figures 1 to 3According to one aspect of this embodiment, the opening construction node includes an I-beam 100, a first fixing member 110, a second fixing member 120, a first receiving member 130, a second receiving member 140, a first assembly 150, and a second assembly 160. The I-beam 100 is installed on a first floor slab 200. The first fixing member 110 and the second fixing member 120 are provided on the I-beam 100. The first fixing member 110 is located on one side of the web 102 of the I-beam 100, and one end of the second fixing member 120 is fixed to the outer side of the lower flange 103 of the I-beam 100. The first receiving member 130 and the second receiving member 140 connect the first floor slab 200 and a second floor slab 300, with the second floor slab 300 located below the first floor slab 200. The first assembly 150 is connected to the connecting member and the I-beam 100 respectively and is located above the opening 400. The second component 160 is disposed on the side of the first component 150, and is connected to the connector, the first floor slab 200 and the second floor slab 300 respectively, and is located on the side of the opening 400.

[0031] According to one aspect of the opening construction details in this embodiment, it is applicable to openings with larger spans. Specifically, during the construction of ALC exterior wall panels, situations often arise where the span far exceeds the design span of existing drawing sets. The ALC exterior wall panels need to be directly connected to the concrete floor slab, requiring consideration of the connection method between the ALC exterior wall panels and the steel beam floor slab on site, as well as the treatment of horizontal joints. In this embodiment, the I-beam 100 is installed on the first floor slab 200. The I-beam 100 is provided with a first fastener 110 and a second fastener 120. The first fastener 110 is located on one side of the web 102 of the I-beam 100, between the upper flange 101 and the lower flange 103 of the I-beam 100. One end of the second fastener 120 is fixed to the outside of the lower flange 103 of the I-beam 100. The first component 150 is installed on the I-beam 100 via the first fastener 110. The second component 160 is respectively located on both sides of the first component 150 and connected to the first component 150 via the first support 130 and the second support 140. The first component 150 is located above the opening 400, and the second component 160 is located on both sides of the opening 400. The first floor slab 200, the second floor slab 300, the first support 130, the second support 140, the first component 150, and the second component 160 together restrict the exit from the opening 400.

[0032] Reference Figure 1 , Figure 2 as well as Figure 6In some embodiments, the first component 150 includes a first wall panel 151 and a second wall panel 152. The first wall panel 151 is mounted on the first fixing member 110 along its length direction. One end of the first wall panel 151 abuts against the first receiving member 130, and the other end of the first wall panel 151 abuts against the second receiving member 140. The first wall panel 151 is connected to the first floor slab 200, the first receiving member 130, and the second receiving member 140 by a limiting member 153. The second wall panel 152 is located below the first wall panel 151 along its length direction and is mounted on the second fixing member 120. One end of the second wall panel 152 abuts against the first receiving member 130, and the other end of the second wall panel 152 abuts against the second receiving member 140. Specifically, the first component 150 includes several first wall panels 151, each of which is an ALC board. The first wall panels 151 are installed along their length on the first fixing member 110. Limiting members 153 are respectively provided on the top of the first wall panels 151 and at both ends in the width direction. The limiting members 153 are respectively installed on the first floor slab 200, the first receiving member 130, and the second receiving member 140. The limiting members 153 can be U-shaped, with the opening of the U-shaped limiting member 153 facing the thickness direction of the first wall panel 151. The first wall panels 151 are engaged in the groove of the U-shaped limiting member 153, so that the first wall panels 151 are fixed and limited by the U-shaped limiting member 153. The second wall panel 152 is installed below the first wall panel 151 along its length direction, and is installed on the second fastener 120 set on the I-beam 100 and fixed by the second fastener 120. The two ends of the second wall panel 152 along its width direction respectively abut against the first receiving member 130 and the second receiving member 140.

[0033] In some embodiments, to better support and fix the first wall panel 151, a support member 111 is further included. The support member 111 is installed on the first fixing member 110, and the lower end of the first wall panel 151 along its length direction is supported by the support member 111. Specifically, the support member 111 is provided on the first fixing member 110. The support member 111 may be L-shaped, with one end of the L-shaped support member 111 installed on the first fixing member 110 and the other end of the L-shaped support member 111 contacting the lower end of the first wall panel 151 to support the first wall panel 151. Alternatively, the support member 111 may not be L-shaped; it may also be provided on the I-beam 100. Here, the support member 111 only needs to provide support and fixation for the first wall panel 151.

[0034] It is understood that the support member 111 in this embodiment can be processed and formed in various ways. For example, it can be formed as a single integral component by injection molding, or it can be a component formed by combining several parts. For example, the first support part and the second support part can be manufactured separately, and then the first support part and the second support part can be connected by welding to form an L-shaped support member 111. In some embodiments, the L-shaped support member 111 can be formed by cutting and bending a metal plate, such as a steel plate. It is conceivable that metal plates, such as steel plates, are widely available on the construction site, easy to manufacture, and have low cost. Therefore, the L-shaped support member 111 can be formed by bending a steel plate, which is simple to process, improves construction efficiency, and reduces costs. In addition, in order to fix the support member 111 to the first fixing member 110 and stably support the first wall panel 151, the support member 111 can be installed on the first fixing member 110 or the I-beam 100 by welding or bolt connection. The specific installation method can be selected according to the actual situation of the construction site, which will not be elaborated here.

[0035] In some embodiments, multiple second wall panels 152 are arranged in the vertical direction, and the multiple second wall panels 152 are connected sequentially from top to bottom. The second wall panels 152 are respectively installed on the second fasteners 120. The first component 150 also includes a first fixing part 170, which is respectively disposed at both ends of the second fastener 120. One end of the first fixing part 170 is connected to the second fastener 120, and the other end passes through and fixes the second wall panel 152. Specifically, the second wall panel 152 is arranged in the vertical direction below the first wall panel 151. The number of second wall panels 152 to be laid is determined according to the specific conditions of the construction site, the dimensions of the first wall panel 151 and the second wall panel 152, and the dimensions of the required opening 400. The first fixing part 170 is respectively disposed at both ends of the second fastener 120. One end of the first fixing part 170 is connected to the second fastener 120, and the other end passes through and fixes the second wall panel 152. It is conceivable that, in order to improve the connection stability between the second wall panel 152 and the first wall panel 151 and the second fixing member 120, there can be multiple first fixing parts 170. It is also conceivable that, when multiple second wall panels 152 are provided, a corresponding first fixing part 170 can be provided for each second wall panel 152. In some embodiments, the second fixing member 120 and the first fixing part 170 can be provided at both ends and the middle portion of the second wall panel 152 respectively, further improving the installation stability of the second wall panel 152.

[0036] Reference Figure 4In some embodiments, the first fixing part 170 includes a fastener 171, a first connector 172, and a fixing rod 173. One end of the fastener 171 is mounted to the second fixing part 120, and one side of the other end of the fastener 171 is mounted to the second wall panel 152. The first connector 172 is S-shaped, and one end of the first connector 172 is connected to the other side of the other end of the fastener 171, thus pressing the fastener 171 tight. One end of the fixing rod 173 is connected to the first connector 172, and the other end of the fixing rod 173 passes through and fixes the second wall panel 152. Specifically, the first fixing part 170 is used to fix the second wall panel 152 to the I-beam 100 via the second fixing part 180. To make the second wall panel 152 more securely fixed, the first fixing part 170 includes a fastener 171 with one end installed on the second fixing member 120. The fastener 171 can be L-shaped. One end of the fastener 171 is installed on the second fixing member 120, and the other end is installed on the second wall panel 152. The fastener 171 and the second fixing member 120 can be installed by welding or by bolt connection. The first fixing part 170 also includes a first connecting member 172, which includes a first end and a second end. The first end is higher than the second end in the horizontal direction. The lower surface of the first end is connected to the upper surface of the fastener 171, and the lower surface of the second end is connected to the second wall panel 152. A fixing rod 173 is provided on the second end. The fixing rod 173 passes through the second end and inserts into and fixes the second wall panel 152.

[0037] In some embodiments, multiple first wall panels 151 are arranged along their length direction, and the multiple first wall panels 151 are connected to each other along their length direction. A second fastener 120 is provided at the joint of two first wall panels 151, and a support member 111 is provided on the second fastener 120. One end of each of the two first wall panels 151 overlaps with the support member 111. Specifically, in some embodiments, depending on the span of the required door and window opening 400 on site, two first wall panels 151 can be set along their length direction, and the two first wall panels 151 are connected end to end along their length direction. In this case, one end of one first wall panel 151 abuts against the first receiving member 130, and one end of the other first wall panel 151 abuts against the second receiving member 140. A second fastener 120 is provided at the joint of the two first wall panels 151. In order to better provide support for the two first wall panels 151, a support member 111 is provided on the second fastener 120, and one end of each of the two first wall panels 151 overlaps with the support member 111. It is understandable that multiple limiting members 153 may be provided at the left and right ends and above the two first wall panels 151 to better limit and fix the two first wall panels 151 respectively.

[0038] In some embodiments, multiple second wall panels 152 are arranged along their length direction, and the multiple second wall panels 152 are connected to each other along their length direction. A second fastener 120 is provided at the connection point of two second wall panels 152, and a support member 111 is provided on the second fastener 120. One end of each of the two second wall panels 152 is respectively connected to the support member 111. Specifically, the second wall panels 152 are connected below the first wall panel 151. When multiple first wall panels 151 are arranged along their length direction, the number of second wall panels 152 arranged below the first wall panel 151 is also the same as the number of first wall panels 151 along their length direction.

[0039] In some embodiments, the second component 160 includes a third wall panel 161 and a second fixing part 180. The third wall panel 161 is located on one side of the first receiving member 130 and the second receiving member 140 along its length, with one end abutting against the first floor slab 200 and the other end abutting against the second floor slab 300. One end of the second fixing part 180 is disposed on the lower flange 103 of the I-beam 100, and the other end of the second fixing part 180 passes through and fixes the third wall panel 161. Specifically, the second component 160 is disposed on the sides of the first receiving member 130 and the second receiving member 140, and together with the first component 150, defines the range of the opening 400. Both ends of the third wall panel 161 abut against the first floor slab 200 and the second floor slab 300, respectively, and the third wall panel 161 is fixed to the I-beam 100 by the second fixing part 180. In addition, in order to reinforce the third wall panel 161, a second fixing part 180 is also provided at the position where the third wall panel 161 contacts the second floor slab 300. One end of the second fixing part 180 is fixed to the second floor slab 300, and the other end passes through the bottom end of the third wall panel 161 and fixes it.

[0040] It is understood that the first wall panel 151, the second wall panel 152, and the third wall panel 161 in this embodiment are ALC panels. ALC panels have various dimensions such as different lengths, widths, and thicknesses. Based on the different sizes of ALC panels and the required dimensions of the door and window openings 400, the first wall panel 151, the second wall panel 152, and the third wall panel 161 can be appropriately cut or stacked to meet the requirements of the required door opening dimensions.

[0041] Furthermore, the first receiving member 130 and the second receiving member 140 can be angle steel, disposed between the first floor slab 200 and the second floor slab 300. The area jointly defined by the first receiving member 130, the second receiving member 140, and the first component 150 is the opening 400. To better fix the third wall panel 161, there can be two first receiving members 130 and two second receiving members 140. One first receiving member 130 is disposed at the front end of the third wall panel 161 along the thickness direction, and the other first receiving member 130 is disposed at the rear end of the third wall panel 161 along the thickness direction; one second receiving member 140 is disposed at the front end of the third wall panel 161 along the thickness direction, and the other second receiving member 140 is disposed at the rear end of the third wall panel 161 along the thickness direction.

[0042] Reference Figure 5 In some embodiments, the second fixing part 180 includes a second connector 181 and a third connector 182. One end of the second connector 181 is fixed to the lower flange 103 of the I-beam 100, and the other end of the second connector 181 is connected to the third connector 182. The other end of the third connector 182 passes through and fixes the third wall panel 161. Specifically, the second connector 181 is L-shaped, and the third connector 182 is J-shaped. One end of the second connector 181 is fixedly installed on the lower flange 103 of the I-beam 100, and the other end of the second connector 181 is connected to the third wall panel 161. The second connector 181 and the I-beam 100 can be installed by welding or by pre-drilling holes in the second connector 181 and the I-beam 100 and then installing bolts. One end of the third connector 182 is connected to the end of the second connector 181 that is connected to the third wall panel 161, and the other end of the third connector 182 passes through and fixes the third wall panel 161.

[0043] Reference Figure 7 In some embodiments, the opening construction node of the present invention is included. Specifically, the present invention also provides a building that includes the opening construction node of the above embodiments. The opening construction node in the building of the present invention is applicable to various door and window openings 400, and can define the required door and window openings 400 by means of I-beams 100, first fasteners 110, second fasteners 120, first receiving members 130, second receiving members 140, first components 150, and second components 160.
