DETAILED DESCRIPTION

[0027] In order to facilitate a better understanding of the present invention, the following examples are used to illustrate the present invention in conjunction with the accompanying drawings. These examples belong to the protection scope of the present invention, but do not limit the protection scope of the present invention.

[0028] Example 1

[0029] A modular assembled concrete wall panel connection node, such as Figure 1-Figure 7 As shown, it includes a connecting component 3 connected to the first wall panel 1 and the second wall panel 2 respectively, and also includes: a connecting plate 31, with both ends respectively arranged on the first wall panel 1 and the second wall panel 2; a connecting member 32, one end of which is arranged in the first wall panel 1, and the other end is arranged in the slot 21 at the position corresponding to the second wall panel 2, so that the connecting member 32 can be extended into the slot 21 for connecting the first wall panel 1 and the second wall panel 2; a fastener 33, corresponding to the first hole groove 11 and the second hole groove 22 respectively provided on the first wall panel 1 and the second wall panel 2; the fastener 33 passes through the connecting plates 31 at both ends and is fastened in the first hole groove 11 and the second hole groove 22 respectively.

[0030] The connecting plate is used to connect the first wall panel and the second wall panel, and then the two ends of the connecting plate are fixed to the first wall panel and the second wall panel respectively by fasteners.

[0031] The connecting piece is prefabricated at the same time as the first wall panel, so that part of the connecting piece extends out of the first wall panel and is used to be inserted into the slot of the second wall panel. This not only facilitates positioning when the wall panel is installed, but also plays a role in connecting and tightening, making the connection between the first wall panel and the second wall panel more secure after installation.

[0032] The fasteners can be existing products such as screws and bolts, and are mainly used to fix the corresponding ends of the connecting plates to the first wall panel and the second wall panel respectively.

[0033] When in use, first stand up and fix the first wall panel, then stand up the second wall panel and allow the connecting piece to extend into the slot to connect the two wall panels; install the connecting plate in the first groove and the second groove, and use appropriate fasteners to fix the two ends of the connecting plate respectively.

[0034] Example 2

[0035] like Figure 1-Figure 3 、 Figure 5 As shown, the first hole 11 and the second hole 22 pass through the connecting member 32 respectively.

[0036] like Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 The connecting plate 31 is provided with a first groove 12 and a second groove 23 at positions corresponding to the first wall panel 1 and the second wall panel 2; one end of the fastener 33 in the first groove 12 and the second groove 23 is flush with the side of the first wall panel 1 and / or the second wall panel 2.

[0037] like Figure 1 、 Figure 2 、 Figure 5 As shown, a first sleeve 13 is provided in the first hole 11 ; and a fastener 33 is threadedly connected to the first sleeve 13 .

[0038] like Figure 1 、 Figure 3 、 Figure 5 As shown, a second sleeve 24 is provided in the second hole groove 22 ; and a fastener 33 is threadedly connected to the second sleeve 24 .

[0039] like Figure 1 、 Figure 3 、 Figure 5 As shown, the second sleeves 23 are disposed on both sides of the slot 21 , and the two sleeves are disposed perpendicular to each other.

[0040] The first hole groove and the second hole groove respectively pass through the corresponding positions of the connecting piece, so that the first hole groove and the second hole groove have sufficient length to facilitate the use of fasteners of appropriate lengths. In this way, the fasteners can be connected to the connecting piece to improve the connection strength.

[0041] like Figure 7As shown, the first groove and the second groove are arranged on the sides of the first wall panel and the second wall panel, and their sizes are much smaller than the length and width of the wall panel; in order to improve the stability of the connection, a plurality of first grooves and second grooves can be arranged at intervals in the height direction of the first wall panel and the second wall panel, and the stability of the connection between the wall panels is improved through multiple connection nodes.

[0042] The first wall panel and the second wall panel corresponding to the connecting plate are both provided with a first groove and a second groove, so that the connecting plates and fasteners used are all in the grooves or flush with the side of the wall panel on that side, making it easier to obtain a smooth wall surface when scraping putty during subsequent decoration.

[0043] A first pipe sleeve is provided in the first hole groove. The first pipe sleeve is provided with a thread and can be directly pre-buried in the first wall panel together with the connecting piece, thereby improving the integrity and facilitating fixation and connection.

[0044] A second pipe sleeve is provided in the second hole groove. Since the slot is used to install the end of the connecting piece that is not connected to the first wall panel, the second pipe sleeve consists of two sections and is arranged on both sides of the slot; the second sleeve can be pre-buried in the second wall panel, and a threaded hole can be opened through the position of the second pipe sleeve corresponding to the connecting piece to facilitate connection and fixation with the fastener through threads.

[0045] Example 3

[0046] like Figure 5-Figure 6 As shown, the first wall panel 1 and the second wall panel 2 are connected in a straight line, the connecting plate 31 and the connecting member 32 are also in a straight line, and the two are arranged parallel to each other.

[0047] like Figure 1 、 Figure 3 、 Figure 7 As shown, the first wall panel 1 and the second wall panel 2 are connected in an L shape, the connecting plate 31 and the connecting member 32 are also L-shaped, and the two are arranged parallel to each other.

[0048] In actual use, the connections between concrete wall panels are mainly I-shaped (the first wall panel and the second wall panel are on the same horizontal plane) and L-shaped (the first wall panel and the second wall panel are perpendicular to each other). Since the two concrete wall panels of the I-shaped are on the same horizontal line, while the two concrete wall panels of the L-shaped are perpendicular to each other, the connection components used have certain differences in order to connect the wall panels properly.

[0049] Example 4

[0050] like Figure 1-Figure 3 、 Figure 5 、 Figure 7As shown, the first hole groove 11 passes through the first wall panel 1, and a first nut 14 is provided on the other side of the first wall panel corresponding to the first groove; the first nut 14 can be pre-buried in the first wall panel. When in use, the fastener passes through the connecting plate and the connecting piece in sequence through the first pipe sleeve, and is connected to the first pipe sleeve and the first nut due to threaded connection.

[0051] like Figure 1 、 Figure 3 As shown, the second hole groove 22 passes through the second wall panel 2, and a second nut 25 is provided on the other side of the second wall panel corresponding to the second groove; the second nut 25 can be pre-buried in the second wall panel. When in use, the fastener passes through the connecting plate and the connecting piece in sequence through the second pipe sleeve, and is connected to the second pipe sleeve and the second nut due to threaded connection.

[0052] By setting the first nut and the second nut, the connecting plate can be firmly fixed to the first wall panel and the second wall panel, thereby improving the strength and stability of the connection; the end of the fastener and the first nut and the second nut can be flush with the first wall panel and the second wall panel on that side, thereby avoiding excessive protrusion that affects subsequent decoration.

[0053] In addition, in order to improve the connection stability of the connecting plate, the following settings can be made: the first groove 12 and the second groove 23 are symmetrically arranged on both sides of the first wall panel 1 and the second wall panel 2 respectively; the first groove 12 and the second groove 23 on both sides of the first wall panel 1 and the second wall panel 2 are respectively provided with connecting plates 31, and the fasteners 33 are arranged through the two connecting plates 31; the stability of the connection is improved by using two sets of connecting plates on both sides of the first wall panel and the second wall panel respectively and connecting them through fasteners.

[0054] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include," "comprise," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device.
