Description

Limiting and overlapping structure, ceiling assembly and mounting method of ceiling assembly

Technical Field

The application relates to the technical field of decoration engineering, in particular to a limiting overlap joint structure, a suspended ceiling assembly and an installation method of the suspended ceiling assembly.

Background

In the field of finishing work, roof panels are used in many cases for the decoration of roofs, which are generally installed by means of inverted T-shaped installation keels comprising a base plate for fixing to the roof and a clamping plate perpendicular to the base plate. Correspondingly, a groove needs to be formed in the middle of the side face of the ceiling board in the thickness direction. When the suspended ceiling plate is installed, the clamping plates of the inverted T-shaped installation keels extend into the grooves in the suspended ceiling plate to achieve installation of the suspended ceiling plate, and one suspended ceiling plate is matched with two inverted T-shaped installation keels for use.

However, in the above method for installing the ceiling plate, since the side surface in the thickness direction of the ceiling plate needs to be provided with the groove, and the thickness of the ceiling plate is generally small, the requirement for the accuracy of the groove on the ceiling plate is high, and the ceiling plate is difficult to process; in addition, in order to ensure that the groove wall of the groove on the ceiling plate has enough strength, the requirement on the material of the ceiling plate is higher under the condition that the groove wall of the groove is thinner.

Disclosure of Invention

An object of the application is to provide a spacing overlap joint structure, furred ceiling subassembly and mounting method for solve among the prior art need set up the recess on the furred ceiling board and lead to the higher and higher problem of the processing degree of difficulty of the material requirement of furred ceiling board.

In order to achieve the purpose, the technical scheme is as follows:

in a first aspect, some embodiments of the present application provide a spacing lap joint structure including at least two mounting keels, a first lap joint, and a second lap joint. The installation fossil fragments include the roof and from the width direction of roof opposite both ends to two backup pads that extend with one side of roof, the roof is used for with roof fixed connection and be on a parallel with the roof. The mounting keel further comprises a first mounting structure and a second mounting structure which are respectively connected to the free ends of the two supporting plates, and the first mounting structure and the second mounting structure are located on two sides of the two supporting plates in a back-to-back mode. The first overlapping element is used for being fixedly connected with the ceiling board and overlapping on the first mounting structure. The first bridging piece is in limited fit with the first mounting structure in the width direction of the top plate. The second overlapping element is used for being fixedly connected with the ceiling board and overlapping on the second mounting structure.

When the ceiling board is installed by using the limiting overlap joint structure, the first overlap joint piece and the second overlap joint piece can be fixed on the ceiling board, the installation keel is fixed on the roof, and then the ceiling board is close to the installation keel and is overlapped on the installation keel through the first overlap joint piece and the second overlap joint piece. The mode of this kind of installation furred ceiling board can be fixed in the back that the furred ceiling board is close to the roof with first bridging and second bridging, need not set up the recess on the side of furred ceiling board perpendicular to roof, so reduced the processing degree of difficulty of furred ceiling board. In addition, the ceiling plate made of materials with higher strength does not need to be selected for ensuring the structural strength of the groove wall of the groove, so that the requirement of the ceiling plate on the materials is reduced, and the manufacturing cost of the ceiling plate is also reduced. In addition, because the installation keels are generally long strips, the width direction of the top plate is also the width direction of the installation keels, when the limiting overlap joint structure is installed, the installation keels are arranged at intervals along the width direction of the installation keels, then the ceiling plates are overlapped on the installation keels, the first overlap joint piece and the first installation structure are arranged to be in limiting fit in the width direction of the top plate, the positions of the ceiling plates in the width direction of the installation keels can be limited, therefore, when a plurality of ceiling plates are installed on a roof, as long as the positions of the installation keels are determined, the distance between every two adjacent ceiling plates is also prevented from being manually adjusted, the labor intensity of workers is reduced, and the installation accuracy of the ceiling plates is improved.

In one possible implementation of the first aspect, the first mounting structure includes a first connection plate and a limit plate. The first connecting plate is connected with the corresponding supporting plate and is parallel to the top plate. The limiting plate is connected with the first connecting plate and is perpendicular to the top plate. The limiting plate and the top plate are located on the same side of the first connecting plate. The first strap includes a first securing plate, a first strap plate, and a first transition plate. The first fixing plate is used for being fixedly connected with the ceiling plate and is parallel to the top plate. The first lapping plate is used for lapping on the limiting plate of the first mounting structure. The first transition plate is used for connecting the first fixing plate and the first lapping plate. The first lapping plate is provided with a limiting groove with a notch facing away from the top plate, and the limiting groove is in limiting fit with the free end of the limiting plate in the width direction of the top plate. The first mounting structure and the first lap joint are simple in structural form and easy to realize.

In one possible implementation of the first aspect, the free end of the limit plate is bent to form an arc-shaped arched structure. The limiting groove of the first lapping plate is in limiting fit with the arc-shaped arch structure in the width direction of the top plate. Set up spacing cooperation of spacing groove and arc hunch-up structure, at the in-process of installation furred ceiling board, make things convenient for the spacing groove to clamp on the free end of limiting plate, convenience when having improved this spacing overlap joint structure and using.

In one possible implementation of the first aspect, the free end of the limiting plate is bent away from the support plate to form an arc-shaped arching structure. Thus, when the requirement of the first lap joint piece and the first mounting structure in lap joint is met, the size of the first connecting plate in the width direction of the top plate can be smaller, so that the consumable material of the mounting keel is reduced, and the manufacturing cost of the mounting keel is reduced.

In one possible implementation manner of the first aspect, the limiting groove is formed by bending the first lap plate. The mode of forming the limiting groove is simple and easy to realize.

In one possible implementation of the first aspect, the first fixing plate is located on a side of the first connecting plate away from the roof. In some cases, the first bridging member may not be connected to the edge of the ceiling board, that is, the edge of the ceiling board exceeds the transition plate of the first bridging member in the horizontal direction, and based on this, the first fixing plate is located on the side of the first connecting plate away from the roof, so that in the process that the first bridging member is bridged on the corresponding installation keel, the collision of the ceiling board and the installation keel corresponding to the first bridging member is avoided, and the first bridging member is conveniently bridged on the corresponding installation keel.

In one possible implementation of the first aspect, the second mounting structure includes a second connecting plate connected with the corresponding support plate and parallel to the top plate. The second strap includes a second securing plate, a second strap plate, and a second transition plate. The second fixed plate is used for being fixedly connected with the ceiling plate and is parallel to the top plate. The second lapping plate is parallel to the second fixing plate and is lapped on the second connecting plate. The second transition plate is used for connecting the second fixing plate and the second lapping plate. Thus, for the second bridging member, after the second fixing plate is attached to and fixed on the ceiling plate, the second bridging plate is parallel to the ceiling plate, and under normal conditions, the ceiling plate is finally parallel to the roof, then the second bridging plate can also be parallel to the roof, and then the second bridging member is conveniently bridged on the first connecting plate parallel to the roof.

In one possible implementation of the first aspect, the second transition plate is perpendicular to the second fixing plate. The free end of the second connecting plate is turned over towards the roof to form a hem plate perpendicular to the roof, and the second lap plate is lapped on the hem plate.

In one possible implementation of the first aspect, the side of the first fixing plate facing away from the roof is coplanar with the side of the second fixing plate facing away from the roof. Therefore, when the ceiling board is installed, the ceiling board can be ensured to be in a horizontal state after being installed; in addition, when the ceiling tiles of the whole roof are installed by using the limiting and overlapping structure, two adjacent ceiling tiles can use the same installation keel, and in this case, the adjacent ceiling tiles can be coplanar as long as the ceiling tiles of the installation keels are coplanar.

In a possible implementation manner of the first aspect, the limit overlapping structure further comprises a suspension rod, one end of the suspension rod is used for being fixedly connected with the roof, the other end of the suspension rod is connected with the roof, and the installation keel is hung on the roof through the suspension rod.

In a second aspect, some embodiments of the present application provide a ceiling assembly including a ceiling tile and a positive lap joint arrangement as in any of the above-described embodiments. The ceiling board is fixedly connected with the first lap joint piece and the second lap joint piece in the limiting lap joint structure.

Because the furred ceiling subassembly that this application embodiment provided includes as above-mentioned arbitrary technical scheme's spacing overlap joint structure, consequently the same technical problem can be solved to the two to reach the same technological effect.

In a third aspect, some embodiments of the present application provide a method for installing a ceiling assembly according to any one of the above-described aspects. The method comprises the following steps: securing the first strap and the second strap to the ceiling tile; fixing the mounting keel on the roof; the first overlapping element on the ceiling board is overlapped on one mounting keel, and the second overlapping element on the ceiling board is overlapped on the other mounting keel.

Because the method for installing the ceiling component in any one of the technical schemes is suitable for the ceiling component in any one of the technical schemes, the same technical problem can be solved, and the same technical effect can be achieved.

In one possible implementation of the third aspect, the fixing the mounting keel to the roof includes: adjusting the distance between a top plate provided with the keel and the roof; the roof plate is fixed with the roof. Thus, the distance between the ceiling plate of the installation keel and the roof is adjusted, and the distance between the ceiling plate and the roof and the levelness of the ceiling plate can be adjusted according to actual needs. In addition, when a plurality of suspended ceiling plates are installed on the roof, the suspended ceiling plates can be adjusted to be coplanar.

The present application provides a ceiling assembly for decorating a roof.

Referring to fig. 1 and 2, fig. 1 is a schematic view illustrating a usage state of a ceiling assembly 1 according to some embodiments of the present disclosure, and fig. 2 is a schematic view illustrating a structure of the ceiling assembly 1 according to some embodiments of the present disclosure. The X-direction and the Y-direction shown in fig. 2 are defined as two directions perpendicular to each other, and the two directions extend horizontally, and the Z-direction in fig. 1 and 2 extends in a vertical direction, i.e., perpendicular to both the X-direction and the Y-direction.

Some embodiments of the present disclosure provide a ceiling assembly 1, where the ceiling assembly 1 includes a ceiling tile 11 and a spacing lap joint structure 12. The spacing bridging structure 12 includes at least two mounting keels 121 (the spacing bridging structure 12 shown in fig. 1 and 2 includes two mounting keels 121), a first bridging member 122 and a second bridging member 123.

The mounting keels 1211 are elongated structures having a length extending in the Y direction in fig. 2, and the two mounting keels 121 are spaced apart in the X direction. The mounting keel 121 includes a top plate 1211 and two support plates 1212 extending from two opposite ends of the top plate 1211 in a width direction to the same side of the top plate 1211, the top plate 1211 is used for being fixedly connected with the roof 2 and is parallel to the roof 2, wherein the roof 2 extends in an X direction and a Y direction to be in a horizontal state, and the width direction of the top plate 1211 is the X direction in fig. 1. In the mounting keel 121 shown in fig. 1, the support plate 1212 is located on the side of the top plate 1211 remote from the roof 2.

The mounting keel 121 further includes first mounting structures 1213 and second mounting structures 1214 coupled to the free ends of the two support plates 1212, respectively, and in particular, the first mounting structure 1213 is coupled to one support plate 1212 and the second mounting structure 1214 is coupled to the other support plate 1212. The first mounting structure 1213 and the second mounting structure 1214 are located on opposite sides of the two support plates 1212. In the mounting keel 121, a top plate 1211, a support plate 1212, a first mounting structure 1213, and a second mounting structure 1214 are integrally formed.

The first strap 122 is adapted to be fixedly connected to the ceiling tile 11 and to strap over the first mounting structure 1213. The first strap 122 is in a snug fit with the first mounting structure 1213 in the width direction of the top panel 1211 (i.e., the X direction in fig. 1). The second strap 123 is adapted to be fixedly coupled to the ceiling tile 11 and to strap onto the second mounting structure 1214.

In the ceiling module 1 shown in fig. 1 and 2, the first strap 122 is fixed to one side of the ceiling panel 11 in the X direction, and the second strap 123 is fixed to the other side of the ceiling panel 11 in the X direction. Wherein, first overlap joint 122 and second overlap joint 123 are equipped with two respectively, and two first overlap joint 122 are arranged along Y direction interval, and two second overlap joint 123 are set up along Y direction interval.

The side of the ceiling board 11 facing the roof 2 is defined as a back side, the side facing away from the roof 2 is defined as a front side, and the remaining sides are defined as side surfaces. Wherein the first strap 122 and the second strap 123 are both fixed to the back surface of the ceiling panel 11.

When the ceiling panel 11 is installed, the first strap 122 and the second strap 123 are respectively fixed to the back surface of the ceiling panel 11, and the installation keel 121 is fixed to the roof 2. The spacing between the two mounting studs 121 is adjusted so that the spacing between the two mounting studs 121 is adapted to the dimension of the ceiling tile 11 in the X-direction. Then, one side of the ceiling tile 11 in the X direction is overlapped on the first mounting structure 1213 of the corresponding mounting keel 121 by the first overlapping member 122, and finally the other side of the ceiling tile 11 in the X direction is overlapped on the second mounting structure 1214 of the corresponding mounting keel 121 by the second overlapping member 123, so that the mounting of the ceiling tile 11 is completed.

The ceiling board 11 is installed by the above-mentioned spacing overlapping structure 12, and the first overlapping element 122 and the second overlapping element 123 are both fixed on the back of the ceiling board 11, so that the installation of the ceiling board 11 can be completed without forming a groove on the side of the ceiling board 11. The processing difficulty of the ceiling plate 11 is reduced, and the ceiling plate 11 made of materials with higher strength is not required to be selected for ensuring the strength of the groove wall of the groove, so that the manufacturing cost of the ceiling plate 11 can be reduced.

In addition, providing the first strap 122 in a restraining engagement with the first mounting structure 1213 in the X direction may define the position of the ceiling tile 11 in the X direction. In this way, when the roof 2 has a plurality of ceiling panels 11 arranged in the X direction, the position of the ceiling panel 11 is determined by simply determining the position of the mounting keel 121, and the distance between the adjacent ceiling panels 11 is determined accordingly. When the ceiling tiles 11 are installed by using the limiting overlap joint structure 12, after the ceiling tiles 11 are overlapped on the installation keels 121, workers do not need to finely adjust the positions of the ceiling tiles 11 in the X direction, the labor intensity of the workers is reduced, and the installation accuracy of the ceiling tiles 11 is improved.

Note that the support plate 1212 shown in fig. 1 is perpendicular to the top plate 1211. In other embodiments, the support plate 1212 may not be perpendicular to the top plate 1211, for example: the supporting plate 1212 and the top plate 1211 may enclose an acute angle or an obtuse angle, which is not limited in the present application.

In addition, the above description is given by taking an example in which two first straps 122 and two second straps 123 are disposed in one ceiling panel 11. In other embodiments, one, three, four or more first straps 122 may be provided for one ceiling panel 11, and one, three, four or more second straps 123 may be provided for one ceiling panel 11, as long as the installed stability of the ceiling panel 11 is ensured.

It should be further noted that, in the present application, the material of the mounting keel 121, the first bridging member 122 and the second bridging member 123 is not limited, and a metal material, a plastic material or a wood-plastic material may be selected and used.

The structure of the first mounting structure 1213 is explained below. Referring to fig. 1, the first mounting structure 1213 includes a first connection plate 12131 and a restriction plate 12132. The first connection plate 12131 is connected to the corresponding support plate 1212 and is parallel to the top plate 1211, so that the first connection plate 12131 is in a horizontal state. The limiting plate 12132 is connected to the first connecting plate 12131 and perpendicular to the top plate 1211, so that the limiting plate 12132 is in an upright state. The limiting plate 12132 and the top plate 1211 are located on the same side of the first connecting plate 12131, and the limiting plate 12132 is located on the side of the first connecting plate 12131 close to the roof 2.

Illustratively, referring to FIG. 1, first connecting plate 12131 is attached to the free end of the corresponding support plate 1212 remote from top plate 1211 such that first connecting plate 12131 forms an L-shaped structure with support plate 1212. The limiting plates 12132 are connected to the free ends of the first connection plates 12131 away from the corresponding support plates 1212, so that the first connection plates 12131 form an L-shaped structure together with the limiting plates 12132.

Of course, in other embodiments, the first connecting plate 12131 can be connected at other positions of the corresponding support plate 1212, such as at the middle region of the corresponding support plate 1212 in the Z direction, so that the first connecting plate 12131 forms a T-shaped structure with the corresponding support plate 1212. Similarly, the limiting plate 12132 may be connected to the first connection plate 12131 at other positions, such as the middle region of the first connection plate 12131 in the X direction, so that the limiting plate 12132 and the first connection plate 12131 form a T-shaped structure together.

The structure of the first strap 122 will be explained below. Referring to fig. 3, fig. 3 is a schematic structural view of the first strap 122 in the ceiling assembly 1 according to some embodiments of the present disclosure. The first strap 122 includes a first fixing plate 1221, a first strap 1222, and a first transition plate 1223. Referring to fig. 1, a first fixing plate 1221 is used to be fixedly connected to the ceiling plate 11 and is parallel to the top plate 1211. The first strap 1222 is adapted to be attached to the limiting plate 12132 of the first mounting structure 1213. The first transition plate 1223 is used to connect the first fixing plate 1221 and the first strap plate 1222. Referring to fig. 3, the first strap 1222 has a notch facing away from the stopper groove 12221 of the top plate 1211 as shown in fig. 1, and referring to fig. 1, the stopper groove 12221 is in limit-fitting with the free end of the stopper plate 12132 in the width direction of the top plate 1211. Wherein the first fixing plate 1221, the first strap plate 1222, and the first transition plate 1223 together form a Z-shaped structure, and the first fixing plate 1221, the first strap plate 1222, and the first transition plate 1223 are integrally formed. In addition, the first transition plate 1223 is perpendicular to the first fixing plate 1221.

The fixed connection of the first strap 122 to the ceiling tile 11 will now be described. Referring to fig. 3, in some embodiments, the first fixing hole 12211 is formed in the first fixing plate 1221 of the first strap 122, and the first fixing hole 12211 is used to pass through a first connecting member (not shown), which is fixedly connected to the first fixing plate 1221 and the ceiling plate 11.

For example, the first connecting member may be a screw, and in use, the first fixing plate 1221 of the first strap 122 is attached to a set position on the back surface of the ceiling board 11, and then the first connecting member is screwed into the ceiling board 11 after passing through the first fixing hole 12211, and the first fixing plate 1221 is pressed against the back surface of the ceiling board 11, so as to fixedly connect the first strap 122 and the ceiling board 11.

The above description is given by taking as an example the fixed connection of the first strap 122 and the ceiling panel 11 by the first connecting member. However, the present application is not limited to the form of the fixed connection between the first strap 122 and the ceiling tile 11. In other embodiments, the first strap 122 may also be fixed to the back surface of the ceiling panel 11 by bonding, which may be specifically: glue is applied between the opposite surfaces of the first fixing plate 1221 and the ceiling tile 11 to achieve the adhesive fixing of the first fixing plate 1221 and the ceiling tile 11, and in this case, the first fixing hole 12211 does not need to be formed in the first fixing plate 1221.

To facilitate the first strap 122 to strap over the first mounting structure 1213, referring to fig. 2, in some embodiments, the free end of the limiting plate 12132 is bent to form an arcuate arching structure 121321. The limit groove 12221 of the first strap 1222 is in limit engagement with the arcuate raised structure 121321 across the width of the top panel 1211. In order to ensure that the limiting groove 12221 and the arched structure 121321 can limit, the size of the limiting groove 12221 is matched with the size of the arched structure 121321.

In this way, during the installation of the ceiling board 11, the limiting groove 12221 of the first strap 1222 can be easily aligned and slid onto the arched structure 121321 on the limiting plate 12132, so that the first strap 1222 can be easily clamped onto the free end of the limiting plate 12132, thereby improving the convenience of using the limiting strap 12.

Of course, in other embodiments, the free end of the limiting plate 12132 may not be provided with the arc-shaped arching structure 121321, and the free end of the limiting plate 12132 is square, and only the limiting groove 12221 on the first bridging plate 1222 is provided as a square groove, and the shape and size of the direction groove are adapted to the shape and size of the free end of the limiting plate 12132, so that the limiting groove 12221 of the first bridging plate 1222 can be snapped onto the free end of the limiting plate 12132, and the first bridging member 122 and the first mounting structure 1213 can be limited in the width direction of the top plate 1211.

In order to reduce the material consumption for installing the keel 121. Referring to fig. 2, the free end of the set of limit plates 12132 is bent away from the support plate 1212 to form an arcuate arching structure 121321. In this way, under the condition that the distance between the arc-shaped arching structure 121321 and the corresponding support plate 1212 satisfies the requirement (i.e. the first bridging member 122 is conveniently lapped on the arc-shaped arching structure 121321, and the first bridging plate 1222 of the first bridging member 122 does not conflict with the support plate 1212), the size of the first connection plate 12131 in the X direction can be set to be smaller, so that the consumable material of the installation keel 121 is reduced, and the manufacturing cost of the installation keel 121 is reduced.

Of course, in other embodiments, referring to fig. 4, fig. 4 is a schematic view of the structure of the mounting studs 121 in the ceiling assembly 1 provided in other embodiments of the present application. In other embodiments, the free end of the limiting plate 12132 may be bent near the support plate 1212 to form an arcuate arching structure 121321, and the same may be used.

In order to reduce the difficulty of manufacturing the first strap 1222. Referring to fig. 3, the stopper groove 12221 is formed by bending the first strap 1222. Therefore, the first strap 1222 does not need to be grooved by machining equipment, thereby reducing the difficulty of manufacturing the first strap 122.

To facilitate the overlapping of the first strap 122 with the corresponding mounting keel 121, referring to fig. 1, in some embodiments, the first securing plate 1221 that provides the first strap 122 is positioned on a side of the first connecting plate 12131 of the mounting keel 121 that is distal from the roof 2.

In some cases, the first strap 122 may not be attached at an edge location of the ceiling panel 11 in the X-direction, i.e., the edge of the ceiling panel 11 exceeds the first transition plate 1223 of the first strap 122 in the X-direction. Referring to fig. 1, a portion of the edge of the ceiling panel 11 shown in fig. 1 that exceeds the first transition plate 1223 of the first strap 122 in the X direction is a portion a.

In the above case, during the process that the first strap 1222 of the first strap 122 is strapped to the first mounting structure 1213 of the corresponding mounting keel 121, the collision of the a portion of the ceiling tile 11 with the corresponding mounting keel 121 of the first strap 122 is avoided, and the smooth mounting of the ceiling tile 11 is ensured.

The structure of the second mounting structure 1214 is explained below. Referring to fig. 1, the second mounting structure 1214 includes a second connection plate 12141, and a second connection plate 12141 is connected to the corresponding support plate 1212 and is parallel to the top plate 1211, so that the second connection plate 12141 is in a horizontal state.

Illustratively, and with reference to FIG. 1, second web 12141 is attached to the free end of corresponding support plate 1212 remote from top plate 1211 such that second web 12141 forms an L-shaped structure with corresponding support plate 1212.

Of course, in other embodiments, the second connecting plate 12141 can be connected at other positions of the corresponding support plate 1212, such as at the middle region of the corresponding support plate 1212 in the Z-direction, so that the second connecting plate 12141 forms a T-shaped structure with the corresponding support plate 1212.

The structure of the second strap 123 will be explained below. Referring to fig. 1, the second strap 123 includes a second fixing plate 1231, a second strap 1232, and a second transition plate 1233. The second fixing plate 1231 is used to be fixedly connected to the ceiling plate 11 and is parallel to the top plate 1211. The second overlapping plate 1232 is parallel to the second fixing plate 1231 and overlaps the second connecting plate 12141. The second transition plate 1233 serves to connect the second fixing plate 1231 and the second bridge plate 1232. Wherein the second fastening plate 1231, the second strap plate 1232, and the second transition plate 1233 together form a Z-shaped structure, and the second fastening plate 1231, the second strap plate 1232, and the second transition plate 1233 are integrally formed.

When the second strap 123 is fixed to the ceiling panel 11, the second fixing plate 1231 of the second strap 123 is attached and fixed to the back surface of the ceiling panel 11. Normally, when the ceiling plate 11 is installed on the roof 2, the ceiling plate 11 is in a horizontal state, and thus, the second overlapping plate 1232 of the second overlapping member 123 is also in a horizontal state. When the installation keel 121 is installed on the roof 2, the second connection plate 12141 is in a horizontal state, and when the second strap 1232 of the second strap 123 is lapped on the second connection plate 12141, the stability is better.

The fixed connection of the second strap 123 to the ceiling panel 11 will be explained below. Referring to fig. 5, fig. 5 is a schematic structural view of the second strap 123 in the ceiling assembly 1 according to some embodiments of the present disclosure. In some embodiments, the second fixing plate 1231 of the second strap 123 is provided with a second fixing hole 12311, and the second fixing hole 12311 is used for passing through a second connecting member (not shown), which is fixedly connected with the second fixing plate 1231 and the ceiling plate 11.

For example, the second connecting member may be a screw, and in use, the second fixing plate 1231 of the second strap 123 is attached to a set position on the back surface of the ceiling board 11, and then the second connecting member is screwed into the ceiling board 11 after passing through the second fixing hole 12311, and the second fixing plate 1231 is pressed against the back surface of the ceiling board 11, so that the second strap 123 is fixedly connected to the ceiling board 11.

The above description is given by taking an example in which the second strap 123 is fixedly connected to the ceiling panel 11 by the second link. However, the present application is not limited to the form of the fixed connection between the second strap 123 and the ceiling tile 11. In other embodiments, the second strap 123 may also be fixed to the back surface of the ceiling panel 11 by bonding, specifically: the same can be used when glue is applied between the facing surfaces of the second fixing plate 1231 and the ceiling tile 11 to achieve the adhesive fixing of the second fixing plate 1231 and the ceiling tile 11, in which case the second fixing holes 12311 need not be provided in the second fixing plate 1231.

In some embodiments, referring to fig. 1, the second transition plate 1233 is perpendicular to the second fixation plate 1231. The free end of the second web 12141 is folded over toward the roof 2 to form a hem panel 121411 perpendicular to the roof 2, and the second strap 1232 is overlapped by the hem panel 121411.

In order to ensure that the ceiling tile 11 is horizontal after installation, referring to fig. 1, a side of the first fixing plate 1221 for facing away from the roof 2 is disposed to be coplanar with a side of the second fixing plate 1231 for facing away from the roof 2. In this way, since the first fixing plate 1221 and the second fixing plate 1231 are both attached and fixed to the back surface of the ceiling panel 11, the ceiling panel 11 can be naturally horizontally positioned after the first strap 122 and the second strap 123 are attached to the corresponding mounting keels 121.

The following describes how the mounting studs 121 are fixedly connected to the roof 2. Referring to fig. 6, fig. 6 is a schematic illustration of the connection of the mounting studs 121 and hanger bars 124 in the ceiling assembly 1 provided by some embodiments of the present application. In some embodiments, the landing gear 12 further includes a hanger bar 124, one end of the hanger bar 124 is used for fixedly connecting with the roof 2, and the other end is connected with the top plate 1211, and the installation keel 121 is hung on the roof 2 through the hanger bar 124.

In an example, the suspension rod 124 is a threaded rod, referring to fig. 2, a through hole 12111 is formed in the top plate 1211 to extend in the Z direction, a lower end of the suspension rod 124 extends through the through hole 12111, two adjusting nuts 125 are screwed onto the suspension rod 124, the two adjusting nuts 125 are respectively disposed on both sides of the top plate 1211 in the Z direction, and the two adjusting nuts 125 clamp the top plate 1211 to fixedly connect the suspension rod 124 and the top plate 1211. The upper end of the boom 124 is connected to the roof 2 by an expansion screw or an expansion bolt. Specifically, because the suspension rod 124 is a threaded rod, the upper end thereof can be fixedly connected with the preset blind hole of the roof 2 through the expansion tube and the nut sleeved at the two ends of the expansion tube, and this connection mode is mature prior art and is not described herein again.

It should be noted that, in order to improve the stability of the installation keel 121 when hanging on the roof 2, set up at least two jibs 124 of every installation keel 121 configuration, each jib 124 is arranged along the length extending direction interval of installation keel 121.

In addition, since the hanger bar 124 is a threaded rod, the hanger bar 124 and the mounting keel 121 can be adjusted in relative position in the Z direction by matching with two adjusting nuts 125, so that the hanging height of the mounting keel 121 can be adjusted, and the top plate 1211 of the mounting keel 121 can be adjusted to be in a horizontal plane.

Referring to fig. 7, fig. 7 is a schematic view of a state in the process of installing a ceiling tile 11 in the ceiling assembly 1 according to some embodiments of the present application. When the ceiling board 11 is installed through the above-mentioned spacing overlapping structure 12, two installation keels 121 may be fixed on the roof 2 through the hanger rods 124 first, then the first bridging member 122 and the second bridging member 123 are fixed on the back surface of the ceiling board 11, then one side of the ceiling board 11 fixing the second bridging member 123 is tilted upward and extended to the upper side of the second installation structure 1214 corresponding to the installation keel 121, then the first bridging plate 1222 of the first bridging member 122 is overlapped on the first installation structure 1213 corresponding to the installation keel 121, and then the ceiling board 11 is rotated with the contact position of the first bridging plate 1222 and the first installation structure 1213 as the rotation center until the second bridging member 123 is overlapped on the second installation structure 1214 corresponding to the installation keel 121. The ceiling tile 11 is in a horizontal state when the second strap 123 is strapped to the second mounting structure 1214 corresponding to the mounting runner 121.

The application still provides a spacing overlap joint structure, and the structural style of this spacing overlap joint structure is the same with the structure of the spacing overlap joint structure 12 in the above-mentioned furred ceiling subassembly 1, and here is no longer repeated.

It should be noted that, the above step S101 and step S102 do not have a requirement of a sequential order, and any one of the two steps may be performed first.

To facilitate adjusting the levelness of each mounting keel 121 and the distance of each mounting keel 121 from the roof 2, referring to fig. 9, fig. 9 is a second flowchart of a method for mounting the ceiling assembly 1 according to some embodiments of the present application. The above step S102 includes S1021 and S1022 shown in fig. 9:

and S1021, adjusting the distance between the top plate 1211 of the installation keel 121 and the roof 2.
