Description

Technical Field

[0001] The present invention relates to the technical field of decoration design.

[0002] In particular, the present invention relates to a connection structure and installation method of a wall keel. Background Art

[0003] The current decoration industry is developing towards the direction of industrialized modular installation. Generally speaking, wall decoration is a commonly used decoration method in interior design, which can increase the sense of hierarchy of the interior space and play a role in beautification and decoration. In particular, the wall hard-packed structure has a very good decorative effect in the decoration process of conference venues, so hard-packed decoration is an indispensable part of such decoration projects.

[0004] In the construction process of traditional hard-packed structures, density boards are inevitably used, and glue is generally used for fixing on site. The use of density boards and glue makes the hard-packed structures unable to play an effective fireproof role. In addition to the complex installation of the structure, in order to ensure the sound insulation and fireproofing capabilities of the hard-packed structure, the thickness of the entire hard-packed structure is usually thick, which affects the usable space indoors. Therefore, now more and more attention is paid to the reasonable installation of the hard-packed structure. For example, the Chinese patent invention patent CN113027064A discloses a compact unit-type wall hard-packed structure. It includes: a through-wall connector, a steel frame, a fireproof integrated board, sound-absorbing cotton, a micro-perforated aluminum plate and a hard-cover cloth. The through-wall connector is fixedly installed on the building base. The surface of the building base is paved with a brick wall. The through-wall connector is penetrated through the brick wall. The steel frame is fixedly installed on the through-wall connector. The steel frame includes a rectangular frame structure formed by welding a number of steel square tubes. A number of cavities are formed on the steel frame. The fireproof integrated board is provided with a groove corresponding to the shape of the steel frame. The steel frame is clamped in the groove. The sound-absorbing cotton is arranged in the cavity. The micro-perforated aluminum plate is fixedly installed on the fireproof integrated board. The hard-cover cloth is fixedly installed on the micro-perforated aluminum plate. The above invention discloses a compact unit-type wall hard-cover structure. The overall thickness of the hard-cover surface is small. It adopts an assembled installation structure to reduce the use of glue and has good sound insulation and fireproofing effects.

[0005] However, the above-mentioned hard-packed structure still has the following problems: the keel in the installation structure is a cross-shaped steel frame formed by welding horizontal and vertical square tubes, and the vertical and horizontal square tubes cannot be located in the same plane, so a single clamp cannot achieve uniform force on the left and right sides, and therefore cannot achieve stable clamping of the clamp, resulting in poor stability of the entire hard-packed wall structure.

[0006] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable and efficient connection structure and installation method of wall keels used in hard-pack wall structures. Summary of the invention

[0041] Embodiment 1: Figures 1 to 6The figure is only one of the embodiments of the present invention, a connection structure of a wall keel, including a connection seat 1 connected to the wall, a cushion block 3 arranged in the connection seat 1 and a support member 2 for carrying a keel frame 4, the connection seat 1 is provided with an installation cavity 11 for convenient installation of the cushion block 3, the support member 2 includes a supporting cross plate 21 and a first baffle 22 arranged at the end of the cross plate 21, a first movable column 12 is arranged in the installation cavity 11, a first through hole 14 for facilitating the passage of the first movable column 12 and a second through hole 15 for facilitating the passage of the support member 2 are arranged on the side of the connection seat 1 away from the wall, a limiting baffle 16 arranged vertically to the first movable column 12 is arranged at one end of the first movable column 12 close to the first through hole 14, the lower end of the limiting baffle 16 is connected to the upper side of the cross plate 21, the lower side of the cross plate 21 is provided with a second movable column 13, and the installation cavity 11 is provided with a first movable column 12 for facilitating The accommodating cavity 111 of the second movable column 13 extends downward, and the first movable column 12 is provided with a first spring 121 at one end away from the first through hole 14. The second movable column 13 is provided with a second spring 131 for driving the second movable column 13 to press against the lower side of the cross plate 21, and the cushion block 3 is provided with a receiving groove 31 for facilitating the insertion and sliding of the support member 2, so that when the first baffle plate 22 slides to the bottom of the receiving groove 31, the support member 2 is located in the second through hole 15 for convenient transportation; and when the first baffle plate 22 slides out of the receiving groove 31 until the first baffle plate 22 presses against the side of the limit baffle plate 16 close to the receiving groove 31, the second movable column 13 is pressed downward under the gravity of the support member 2, and the limit baffle plate 16 also moves downward so that the first movable column 12 extends outward through the first through hole 14, so that the first movable column 12 and the cross plate 21 clamp the keel frame 4.

[0042] In the present invention, the cushion block 3 is pre-installed in the installation cavity 11 of the connecting seat 1, and the support member 2 is also located in the installation cavity 11 and connected with the cushion block 3 when it is stored; when the keel frame 4 needs to be installed, the support member 2 is unfolded outward, and under the movement of the first movable column 12 and the second movable column 13, the first movable column 12 and the cross plate 21 of the support member 2 tightly clamp the horizontally arranged keel in the keel frame 4.

[0043] First, when the entire connecting structure is stored, in the connecting structure, the cushion block 3 is installed in the mounting cavity 11 of the connecting seat 1, the cushion block 3 is arranged in a C shape, and a receiving groove 31 opening in the direction of the keel frame 4 is arranged on the cushion block 3; the first movable column 12 is also installed in the mounting cavity 11 and is located above the cushion block 3, the first movable column 12 is arranged horizontally and extends toward the first through hole 14 under the elastic force of the first spring 121; the support member 2 is also at least partially located in the mounting cavity 11, and the first baffle plate 22 on the innermost side of the cross plate of the support member 2 extends to the bottom of the receiving groove 31 (or the first baffle plate 22 extends into the receiving groove 31 to the extreme position); a second movable column 13 is arranged below the cross plate 21 to push the cross plate 21 upward under the action of the second spring 131; a limit baffle 16 is arranged above the cross plate 21 for blocking the first movable column 12 from passing through the first through hole 14.

[0044] Of course, a second baffle 23 is provided at one end of the horizontal plate 21 away from the first baffle 22, and a groove 17 for facilitating the embedding of the second baffle 23 is provided on the side of the connecting seat 1 away from the wall. When the first baffle 22 extends to the bottom of the storage groove 31, the second baffle 23 is just embedded in the groove 17.

[0045] Then, when installing the keel frame 4, the entire connection structure needs to be unfolded. The support member 2 only needs to be pulled outward until the first baffle 22 on the horizontal plate 21 moves to abut against the inner side of the limit baffle 16. At this time, the keel frame 4 can be installed on the horizontal plate 21.

[0046] Of course, under the gravity of the support member 2 and the keel frame 4, the support member 2 will be pressed down. At this time, the second spring 131 of the second movable column 13 is not enough to support this gravity, then the support member 2 and the second movable column 13 will move downward, and the second movable column 13 will retract into the accommodating chamber 111. The descent of the support member 2 will also cause the limit baffle 16 to descend. At this time, after the front end of the first movable column 12 is unobstructed, the first movable column 12 extends forward through the first through hole 14 under the elastic force of the first spring 121, thereby completing the deployment of the entire connecting structure.

[0047] Finally, the keel frame 4 is clamped by the connecting structure. When the entire connecting structure is unfolded, the first movable column 12 just presses against the upper surface of the keel frame 4. Even if the second movable column 13 retracts, the elastic force of the second spring 131 is still there, which will squeeze upward appropriately. Then the cross plate 21 will also squeeze the keel frame 4 upward so that it presses tightly against the first movable column 12. Then the keel frame 4 (in the up and down direction) is tightly clamped between the cross plate 21 and the first movable column 12.

[0048] Moreover, the existence of the second baffle 23 also prevents the keel frame 4 from falling away from the connecting seat 1. The keel frame 4 is located between the connecting seat 1 and the second baffle 23 in the left and right directions, so that the keel frame 4 is limited in four directions and has better stability after installation.

[0049] It is even possible to set a return spring between the first baffle plate 22 and the bottom of the storage groove 31, so that after the keel frame 4 is installed, the return spring pulls the entire support member inward to press the keel frame 4, so that the keel frame 4 (in the left and right directions) is tightly clamped between the second baffle plate 23 and the connecting seat 1.

[0050] It should be noted that the keel frame 4 includes a first keel 41 and a second keel 42 which is arranged perpendicular to the first keel 41, and at least a part of the first keel 41 is located in the area surrounded by the transverse plate 21, the second baffle plate 23, the first movable column 12 and the connecting seat 1. Here, the first keel 41 is a horizontal keel, the second keel 42 is a vertical keel, the first keel 41 and the second keel 42 are not on the same plane, and the first keel 41 is closer to the wall; that is, when the keel frame 4 is installed on the support member 2, the first keel 41 which is closer to the wall is adjusted to a horizontal extension setting, and then the first keel 41 is mounted on the transverse plate 21.

[0051] In summary, the steps for connecting and installing the keel in a connection structure of a wall keel of the present invention are as follows: first, install the pad block 3 and the support member 2 on the connecting seat 1, so that the pad block 3 is inserted into the installation cavity 11 of the connecting seat 1, the cross plate 21 of the support member 2 is inserted into the storage groove 31 of the pad block 3 and the first baffle 22 at the end of the cross plate 21 is against the bottom of the storage groove 31, at this time, the first movable column 12 located on the upper side of the pad block 3 is blocked by the limiting baffle 16 on the upper side of the cross plate 21, and the second movable column 13 is supported to the lower side of the cross plate 21 under the elastic force of the second spring 131; then the above-mentioned assembled connecting components are transported to the installation position of the keel frame 4, and the connecting seat 1 is installed to the wall On; then pull the support member 2 outward through the second through hole 15 until the first baffle 22 abuts against the side of the limit baffle 16 close to the pad 3; at this time, the transverse keel in the keel frame 4 is mounted on the transverse plate 21 of the support member 2; under the action of the gravity of the keel frame 4 and the support member 2, the support member 2 presses down the second movable column 13 and descends together, so that the limit baffle 16 also descends together; finally, after the limit baffle 16 leaves the front of the first movable column 12, the first movable column 12 extends out of the first through hole 14 under the elastic force of the first spring 121, and at this time, the lower side of the first movable column 12 just contacts the upper side of the transverse keel in the keel frame 4, completing the installation of the keel frame 4.

[0052] The wall keel connection structure of the present invention has a simple structure, is stably clamped to the steel frame keel, has a high stability of the hard package structure of the entire wall, and the entire connection structure can be stored for easy transportation, and can be popped out for clamping during installation, so the installation is convenient.

[0053] Embodiment 2, still as Figures 1 to 6 The figure shown is only one of the embodiments of the present invention. On the basis of the first embodiment, in a connection structure of a wall keel of the present invention, a toggle block 24 is provided on the side of the horizontal plate 21 away from the second baffle plate 23. The toggle block 24 is a conical plate. When the connection structure is unfolded, it is convenient for the construction workers to pull the support member 2 outward through the toggle block 24.

[0054] Furthermore, both upper and lower sides of the horizontal plate 21 are provided with dovetail grooves 211, the lower end of the limit baffle 16 is provided with a first plug block 161 for inserting into the dovetail groove 211 on the upper side of the horizontal plate 21, and the upper end of the second movable column 13 is provided with a second plug block 133 for inserting into the dovetail groove 211 on the lower side of the horizontal plate 21. In this way, the horizontal plate 21, the limit baffle 16 and the second movable column 13 can only be relatively displaced in the horizontal direction, and cannot be mutually displaced in the vertical direction, so when the first keel 41 is placed on the horizontal plate 21, the horizontal plate 21, the limit baffle 16 and the second movable column 13 are synchronously lowered.

[0055] In addition, a first limiting plate 122 is provided at one end of the first movable column 12 close to the first spring 121, and the width of the first limiting plate 122 is greater than the aperture of the first through hole 14; a second limiting plate 132 is provided at one end of the second movable column 13 close to the cross plate 21, the second spring 131 is sleeved on the outside of the second movable column 13, and the width of the second limiting plate 132 is greater than the outer diameter of the second spring 131, and the second insert block 133 is provided on the side of the second limiting plate 132 away from the second movable column 13.

[0056] Finally, a wing plate 18 is provided on the outer periphery of the connecting seat 1 on the side close to the wall, and a countersunk hole 181 is provided on the wing plate 18 for facilitating the installation of expansion screws.
