Detailed ways

First of all, the original design intention of the present invention will be explained. The vertical keel is the main force-bearing component in the wall skeleton. The existing installation process of the top keel and the vertical keel is complicated, and the workers need to spend a lot of time. The accuracy between the keels cannot be adjusted, and repeated disassembly and installation will damage the wall. Therefore, the present invention proposes a connection structure between the vertical keel and the top keel.

The present invention will be described in detail below in conjunction with the accompanying drawings. As shown in Figures 1-2, a vertical keel and top keel connection structure includes a vertical keel 1 and a top keel 2. In order to facilitate the vertical keel 1 and the top keel 2 For connection and installation, a mounting hole 3 is arranged on the top keel 2, and a plurality of rows of adjustment holes 4 are arranged on the vertical keel 1. This mounting hole 3 includes a horizontal mounting hole 32 and a longitudinal mounting hole 31. The mounting holes 3 are in the form of With a certain regular distribution, in order to ensure the strength and rigidity of the vertical keel 1, several U-shaped grooves 11 are punched in an orderly manner on the main surface of the vertical keel 1.

The number of the vertical mounting holes 31 in each row is M, the number of rows of the vertical mounting holes 31 is N, and the holes in each group of the horizontal mounting holes (32) are numbered first from left to right. ~N holes, the horizontal mounting holes 32 have M groups, and the horizontal mounting holes 32 are sequentially numbered from bottom to top as the first to M groups of horizontal mounting holes, the second group of the horizontal mounting holes 32 are arranged in a staggered arrangement, the second The longitudinal hole spacing of any two adjacent holes in the group of lateral mounting holes 32 is less than or equal to B, and the longitudinal hole spacing of the highest hole and the lowest hole in the second group of lateral mounting holes 32 is also less than or equal to B, and in the second group of lateral mounting holes 32 The longitudinal hole distance between the Xth hole and the N-(X-1)th hole in the first group of lateral mounting holes 32 is B or an integer multiple of B, and the Yth group of lateral mounting holes 32 and the Y+1th group The shape of the horizontal mounting holes 32 is e, the shape of the Y-th group of horizontal mounting holes 32 and the Y-1 group of horizontal mounting holes 32 is f, and the shape f is the center point of the line connecting the head and tail holes of the Y-th group of horizontal mounting holes 32 Rotate the axis upward by 180 degrees to obtain the shape e, 1≤X≤N and X is an integer, 1≤Y≤M and X is an integer.

When making the top keel, 2 to 8 sets of transverse mounting holes 32 can be arranged.

When making a convenient top keel, the transverse mounting holes 32 are divided into 4 groups, which are the first group of transverse mounting holes 5, the second group of transverse mounting holes 6, the third group of transverse mounting holes 7, and the fourth group of transverse mounting holes from bottom to top. The horizontal mounting hole 8, the second group of horizontal mounting holes 6 and the first group of horizontal mounting holes 5 are formed by taking the center point of the line connecting the head and tail holes of the second group of horizontal mounting holes 6 as the axial direction and rotating 180 degrees to obtain the third group of horizontal mounting holes. The shape formed by the mounting hole 7 and the second group of horizontal mounting holes 6, the shape of the third group of horizontal mounting holes 7 and the second group of horizontal mounting holes 6 is based on the center point of the line connecting the first and last holes of the third group of horizontal mounting holes 7 as the axis Rotate up 180 degrees to obtain the shape formed by the fourth set of lateral mounting holes 8 and the third set of lateral mounting holes 7 .

The number of rows of the adjustment holes 4 is greater than or equal to the number of rows of the longitudinal installation holes 31 , and the plurality of rows of adjustment holes 4 are arranged in a rectangular array as a whole, which is convenient for installing the vertical keel 1 and the top keel 2 , and the several rows of longitudinal installation holes 31 The horizontal column spacing of 4 is compatible with all or part of the horizontal column spacing of the multi-column adjustment holes 4. The hole spacing of the two adjacent holes on the upper and lower sides of the adjustment holes 4 in each row is B, and the value of B is greater than the diameter of the adjustment holes. Also larger than the diameter of the mounting hole.

Before installation, in order to facilitate positioning, the installation holes 3 in the middle row are connected to each other in the oblong hole 9, and screws or rivets are used as the fixing member 10 to fix the vertical keel 1 and the top keel 2, and the screws first pass through the oblong hole 9. It is fixed with one of the holes in the middle row of the adjustment holes 4, and then, through the other overlapping installation holes 3 and adjustment holes 4, the fixing is realized.

Since the longitudinal hole distance B between adjacent holes in each row of adjustment holes 4 can be increased by increasing the number of rows of installation holes 3 The longitudinal hole spacing of every two adjacent holes in the 2 groups of transverse mounting holes is infinitely evenly divided to reduce the B value, so as to achieve a relatively high-precision distance adjustment. The mounting holes 3 are distributed regularly. When an adjustment hole 4 overlaps, there must be one or more installation holes 3 overlapping with the adjustment hole 4 in other columns of the installation hole 3 that are symmetrical with the longitudinal centerline. The structure can be fixed on the side of the wall or on the top of the wall. The fixed position can be quickly adjusted according to the actual situation, which can realize the fine adjustment of precision, improve the construction efficiency, simplify the installation process, and reduce the time required for the ceiling to a greater extent. The workload can be quickly positioned and fixed, the installation is firm and stable, the labor intensity is low, the positioning is accurate, and the operation can be completed by one person. In addition, the distribution rules of the installation holes of the top keel and the adjustment holes of the vertical keel are interchangeable. The above-mentioned beneficial effects can also be achieved.

In the actual operation process, the B value is generally 5 mm to 20 mm, the longitudinal hole distance of each adjacent two holes of the second group of lateral mounting holes is 1 mm to 8 mm, the highest hole of the second group of lateral mounting holes and The longitudinal hole spacing value of the lowest hole is 5 mm to 20 mm.

In the process of ceiling suspension, the allowable value of adjustment error is generally within 5 mm. Therefore, the B value can be 10 mm, the second group of lateral mounting holes can be set to 7, the middle hole is the highest, the three holes on the left and right sides of the middle hole can be staggered downward, and the longitudinal hole spacing of the highest hole and the lowest hole is also The B value is 10 mm, so the vertical hole distance between the two adjacent holes in the second group of lateral mounting holes is 3.3 mm, and the minimum adjustment accuracy is also 3.3 mm; of course, the second group of lateral mounting holes are the middle and the highest hole left three. The holes can be set to have a longitudinal hole spacing of 5/3 mm for each adjacent hole, and the 3 holes on the right side of the highest middle hole can be set to a longitudinal hole spacing of 10/3 mm for each adjacent hole, so that the minimum precision value can be adjusted to 5/3 mm.
