Description

Peripheral hardware connection structure's assembled panel

Technical Field

The invention belongs to the technical field of assembly type buildings, and particularly relates to an assembly type plate with an external connection structure.

Background

The fabricated building is a building which is formed by transferring a large amount of field operation work in the traditional construction mode to a factory, processing and manufacturing building components and accessories (such as floor slabs, wall slabs, stairs, balconies and the like) in the factory, transporting the components and accessories to a building construction site, and assembling and installing the components and the accessories on the site in a reliable connection mode. The prefabricated building mainly comprises a prefabricated concrete structure, a steel structure, a modern wood structure building and the like, and is a representative of a modern industrial production mode due to the adoption of standardized design, factory production, assembly construction, informatization management and intelligent application.

Among these, panel construction is a common type of application in prefabricated construction. It is mainly assembled by prefabricated large-scale inner and outer wall boards, floor slabs, roof slabs and other boards, and is also called as a large-board building. The plate building can reduce the weight of the structure, improve the labor productivity and enlarge the use area and the shockproof capability of the building. The inner wall board of the plate building is mostly a solid board or a hollow board made of reinforced concrete; the external wall board is mostly a reinforced concrete composite board with a heat-insulating layer, and can also be made of light aggregate concrete, foam concrete or macroporous concrete and the like to form the wall board with an external decorative surface. Equipment within a building often employs centralized indoor plumbing fittings or box toilets, etc., to enhance the degree of assembly. The key problem of the plate building is node design, and the structural integrity of the member connection is ensured (the connection method between the plates mainly comprises welding, bolt connection and post-cast concrete integral connection). The waterproof structure is to properly solve the problems of waterproof of the joints of the external wall panels, thermal treatment of building joints and corner parts and the like. The main disadvantage of the large-plate building is that the building shape and layout are greatly restricted; the internal separation of large-plate buildings with small compartments and transverse bearing is lack of flexibility (the internal separation of longitudinal wall type, inner column type and large-span floor type can be flexibly carried out).

In the present panel building, it is comparatively common for the mode of connecting to use the screw rod, nevertheless because its screw rod connecting piece all sets up inside panel, when it formed complete building structure, can't follow outside direct detection and whether its connection is firm. Then the connection mode cannot pass the acceptance smoothly according to the existing acceptance specifications of the construction industry. Meanwhile, if maintenance is carried out in the later period, special inspection or reconnaissance instruments are required to be adopted to check the joints, and potential hazards can not be found in time.

Generally, a plurality of groups of connecting grooves are symmetrically arranged on two large-area surfaces of the plate body, and the connecting grooves are clamped and tensioned from two sides, so that good connecting stability is formed.

However, it should be noted that the number and the arrangement positions are not limited in the claims, and the rod members are arranged on only one side of the plate body, and the fixing effect can be achieved by optimizing the specific structure and the connection mode, and the scheme of arranging the rod members on one side or two sides is within the protection scope of the present invention.

The plate body is connected with the plate body to form a wall body, and the plate body at the end part of the wall body is connected with other plate bodies or fixed structures through connecting pieces. If the board body is connected with other board bodies, a corner is formed, and an independent room is formed by enclosing. The fixing structure is generally a main structure of a building formed by pouring, and the rod members are inserted into the fixing structure, and the plate bodies are arranged along the rod members in sequence and then abutted against the fixing structure through the locking members. And then the plate bodies are fixed in sequence, and each plate body or a plurality of plate bodies are continuously fixed by using the locking piece after being connected.

The locking piece is sleeved on the rod piece, the plate body is pushed to one side by external force, the plate body is kept stable under the continuous action of the external force, and the locking piece is operated to abut against one side of the plate body and form a fixed relation with the rod piece. Then the external force is removed, and the plate body is locked and fixed.

It is also worth mentioning that the term "bar" means a member having a dimension in the longitudinal direction (length direction) that is much larger than the dimension in the transverse direction (perpendicular to the length direction), and that members having a dimension in the length direction that is larger than the dimension perpendicular to the length direction are considered to fall within the scope. Because the mutual fixed connection between the plates is tightened and fixed through the rod piece and the locking piece, the soft steel cable can also be suitable for fixing the structure.

Example 1:

the embodiment discloses a plate structure, mainly uses in the prefabricated building, forms the wall through connecting a plurality of plate bodies 2 parallel, can realize the subregion interval to the inner space through rapid Assembly inside current building body structure.

Specifically, as shown in fig. 1 and 2, the plate mainly includes two parts, wherein four plate bodies 2 are connected with each other in the middle, and fixing columns 1 for fixing are arranged at the end parts of two sides. Wherein, the fixed column 1 is originally for pouring fashioned building main part, forms the wall with plate body 2 setting between two fixed columns 1.

It should be noted that the distance between the fixing posts 1 is much larger than the width of the four standard boards 2 in the actual construction process for the purpose of illustration.

Different from the prior art, the four plates are provided with five rod pieces 5 on the inner and outer surfaces, a through connecting groove 3 is arranged on the surface of each plate, and the connecting grooves 3 on the surfaces of the plates after being connected are aligned and communicated. During assembly, one end of the rod piece 5 is fixed in the connecting column at one side through an expansion bolt, and is directly fixed in the fixing column 1 at the left side in the figure. And every time a plate body 2 is arranged, five locking pieces 4 are arranged on the right side of the plate body 2 for tensioning and fixing.

Because the fixed column 1 at the end part of the left side is of a fixed structure, after the rod piece 5 is fixed, the adjacent plate bodies 2 are directly pushed to one side of the fixed column 1 by applying external force from the right side by using an engineering tool, and when the left end surface of each plate body 2 completely abuts against the surface of the fixed column 1, five locking pieces 4 are arranged on the right end surface of each plate body for positioning. Support retaining member 4 on plate body 2 right side through the operation, push down 5 surfaces on the member with the locking structure that retaining member 4 inside has again, make and form spacing relation between retaining member 4 and the member 5, unload external force this moment and install down plate body 2 again.

As can be seen in figure 3, the concave-convex structure 2.1 that the cooperation was pegged graft is equipped with on two thickness place terminal surfaces of plate body 2, on the same plate body 2, the left side is the sand grip structure, and the right side is groove structure, and when adjacent plate body 2 supported and was taut through member 5 and retaining member 4, sand grip and groove combination can prevent that the side direction from applying external force and making its fracture.

And the surface of the plate body 2 in fig. 3 is provided with a square groove 6 in the vertical direction, and the square groove 6 is used for receiving pipelines so as to form a routing arrangement inside the building.

It should be noted that, the plate body 2 in this embodiment is cast and molded in advance through a mold, and then transported to an installation site for assembly according to requirements. The surface notch structure is formed through a mould, and is shielded by coating cement mortar or a veneer after assembly.

Example 2:

in this embodiment, optimization and limitation are performed on the basis of embodiment 1, as shown in fig. 3 and 4, since the inside and the outside of the single plate body 2 are both provided with the corresponding connecting groove 3 structure, and the connecting grooves 3 are correspondingly arranged on the same horizontal plane, a total of two rod members 5 passing through the single locking member 4.

In this embodiment, in order to install the locking member 4, a fastening member 8 is provided on the rod member 5, and can be fixed on the rod member 5, and the fastening member 8 has a pushing rod 10 for pushing the locking member 4 to be attached to the plate body 2. The plate body 2 is equipped with fastener 8 one side and corresponds and is equipped with heavy groove 2.2 structure, and this heavy groove 2.2 structure is for running through the setting in length direction (also be the thickness direction of plate body 2), and heavy groove 2.2 cross-section is the rectangle structure, corresponds with retaining member 4. It can be seen that locking member 4 is provided with two through holes for rod members 5 to pass through.

In order to lock and fix the locking member 4 and the rod member 5, fastening screw holes 15 are formed on two sides of the locking member 4, and the fastening screw holes 15 are communicated with the through hole where the rod member 5 is located. A locking bolt is arranged in the fastening screw hole 15, and the end of the locking bolt is pressed against the surface of the rod piece 5 by screwing the locking bolt so as to achieve the fixing effect.

It should be noted that the locking bolt is only shown inserted in the fastening screw hole 15, and the locking bolt in this embodiment includes two portions, wherein one abutting block 13 is provided at the end. The abutting block 13 is made of plastic and is rotatably connected with the main body structure of the locking bolt. The abutting block 13 can move linearly in the fastening screw hole 15 along with the screwing of the locking bolt, the end part of the abutting block is designed to be a cambered surface, and the abutting block can have a larger contact area on the surface of the abutting rod piece 5.

The arc surface 16.1 of the abutting block 13 is provided with concave-convex lines, and the surface of the contact rod piece 5 is deformed by the extrusion of the locking bolt, so that a larger static friction force is obtained to limit the movement of the locking piece 4. During the installation, need earlier with retaining member 4 remove to heavy inslot 2.2 in, rethread external engineering equipment promotes retaining member 4 and extrudees in to heavy groove 2.2, or continuously outwards pulls member 5. Then keeping the action of external force, inserting locking bolts from two sides for locking, and finally removing the external force to achieve a stable state.

Because this wall body outside can set up decorative board and heat preservation, the spread groove 3 that is equipped with then can carry out the shutoff through filling cement mortar or other gypsum after member 5 is fixed, or directly adopt panel to shelter from the outside to be equipped with the opening in key junction, look over when supplying the later maintenance.

And in this embodiment directly be connected plate body 2 and plate body 2 side, in order to make retaining member 4 not influence the connection stability, then heavy groove 2.2 degree of depth is slightly greater than retaining member 4 width, can sink in heavy groove 2.2 completely when retaining member 4 is fixed.

Example 3:

this embodiment is optimized and limited based on the above embodiment 1, as shown in fig. 5-9, which shows a structure of the locking member 4, different from the above embodiment 2, mainly adjusting the inserting direction of the locking screw 7 and the fixing manner of the locking screw 7, thereby improving the stability.

The locking piece 4 in the embodiment 2 has a simple structure and is convenient to operate, and the locking screws 7 are arranged to be oppositely inserted from two sides in the length direction for the convenience of operation. However, since the width of the whole locking member 4 is not greater than the width of the plate body 2 and the depth of the connecting groove 3 is smaller than the thickness of the plate body 2, the distance between the two rod members 5 passing through the locking member 4 cannot be reduced, and it can be seen that the stroke of the locking screw 7 is short.

In the present embodiment, the plurality of plate bodies 2 are fixedly connected by five inner and outer rod members 5, and the right side of the plate body 2 is provided with a sinking groove 2.2 for fixing the locking member 4. The locking part 4 is internally provided with a through hole and a screw hole, and is also provided with an expansion cavity at the end part of the screw hole, and a pressing block 12 is arranged in the expansion cavity. This compact heap 12 can slide in the inflation intracavity, and the direction of sliding is perpendicular and the member 5 axis, compresses tightly fixedly the side direction to member 5 through this compact heap 12. And the moving direction of the locking bolt is vertical to the moving direction of the pressing block 12, and the pressing block 13 arranged at the end part of the locking bolt is matched with the pressing block 12 to realize transmission.

Specifically, the abutting block 13 is also configured to be able to slide in the expansion cavity, but unlike the above embodiment 2, the abutting block 13 is limited in the expansion cavity and is not connected to the locking screw 7 as a separate structure. But is concavely formed into a concave spherical surface in the contact surface with the locking screw 7 and is pushed by the convex spherical surface at the end part of the locking screw 7. Since the locking member 4 is usually kept in an initial state for a long time after being fixed in consideration of low frequency of attachment and detachment, no return spring structure is provided in the expansion chamber.

In order to realize transmission between the abutting block 13 and the pressing block 12, the contact surfaces of the abutting block 13 and the pressing block 12 are both provided with an inclined surface structure. When the pressing block 13 is pushed by the locking screw 7, the pressing block 13 can transmit the pushing force in the vertical direction to the pressing block 12 through the inclined surface component force. Because the advancing direction of the locking screw 7 is along the axial direction of the rod piece 5, the locking screw is not limited by the length of the locking piece 4, and the fixing effect can be prevented from being influenced by the action of the abutting block 13 during fixing by arranging longer and denser threads.

Also disclosed in this embodiment is a fastener 8 for performing a fixing operation in cooperation with the retaining member 4, and as shown in a partially enlarged view in fig. 6, the fastener 8 is also fitted to the rod member 5, and the fastener 8 is in a gate-shaped configuration in a top view as viewed from above. The fastening member 8 is also provided with a fastening through hole 18 through which the rod 5 passes, and a passage communicating with the fastening through hole 18 is provided at a lower portion. The channel is actually an opening of the fastening through hole 18 at the lower part, so that the rod piece 5 can be directly inserted into the fastening through hole 18 from the lower end, the mode that the fastening piece 8 needs to penetrate from the end part of the rod piece 5 during installation is avoided, and the assembly efficiency is improved.

The fastening element 8 likewise has a compression structure similar to a locking bolt, i.e. a fastening screw 9 in the illustration. The fastening screw 9 is also of a screw structure, but since the whole width of the fastening screw is not required to be considered, a mode of inserting the fastening screw from two sides can be adopted, and protruding extension parts are arranged at corresponding positions of the two sides to increase the stroke of the fastening screw.

The fastener 8 is also provided with a push rod 10, the push rod 10 is in threaded fit with the fastener 8, the end part of the push rod 10 is aligned with the surface of the adjacent locking member 4, and the push rod 10 can abut against the locking member 4 to press the locking member 4 towards the inner part of the sinking groove 2.2 to realize compression after being screwed.

The specific principle is as follows: the locking member 4 is first set in the sinking groove 2.2 and the fastening member 8 is moved to the corresponding position, and the pressing structures on both sides are operated to fix the fastening member 8 on the rod member 5. Then the push rod 10 is screwed, the locking piece 4 is fixed in the sinking groove 2.2 through the push rod 10, at the moment, the locking bolt is operated again to fix and limit, and finally the fastening piece 8 is disassembled to start to install another locking piece 4.

Example 4:

as shown in fig. 10 to 12, the present embodiment also discloses a panel body 2 and a connecting member for connecting the panel body 2 to form a wall body.

Particularly, transversely laminating concatenation including a plurality of plate bodies 2 forms, and the concrete structure of the single plate body 2 of show in the picture pours the shaping through the mould prefabrication. It can be seen that the plate body 2 is a rectangular plate with a long vertical direction, and staggered rectangular grooves are arranged inside and outside in the vertical height direction and are used for arranging circuits, so that wires can be hidden in the plate body 2 after the whole wall surface is formed.

Five equidistant and parallel connecting grooves 3 are respectively arranged on the inner side and the outer side of the plate body 2 in the horizontal direction, the depth of the connecting grooves 3 is larger than that of the rectangular grooves, and the inner bottom is a circular arc bottom surface. When laminating was arranged between plate body 2 and the plate body 2, every spread groove 3 intercommunication each other formed the cell body structure that runs through, is equipped with same member 5 in the spread groove 3 of polylith plate body 2 and connects.

It can be seen that for illustration, two rod members 5 are arranged in the bottom connecting groove 3, a sunken groove 2.2 is arranged on the right side of the plate body 2, a locking member 4 is arranged in the sunken groove 2.2, and the two rod members 5 symmetrically penetrate through the locking member 4 and are fixed and tensioned through the locking member 4.

In fig. 12 it can be seen that the locking member 4 has two locking through holes 11 for the rods 5 to pass through. The lower part of the locking through hole 11 is hollowed to form an opening, and the width of the opening is greater than or equal to the diameter of the cross section of the locking through hole 11. Because locking through-hole 11 structural design originally makes retaining member 4 need penetrate from member 5 tip when the installation and fix, the opening that then is equipped with makes member 5 can follow the lower part and get into locking through-hole 11 perpendicularly in, the installation of being convenient for. The locking piece 4 can be restrained by a sunk groove 2.2 arranged on the side surface of the plate body 2, and the locking piece can be prevented from sliding out from the upper part and losing connection with the rod piece 5.

Two dovetail grooves in the same direction as the axis direction of the through hole are arranged on the inner wall of the opening, and an inserting block 16 is connected in a matched manner through the dovetail grooves. The insert 16 can be inserted along the axial direction of the locking through hole 11, two inserts corresponding to the dovetail grooves are arranged on the insert 16, a through fixing hole is formed in each insert, and the insert 16 is fixed on the locking piece 4 through an inserted bolt.

It can be seen that the insert 16 is provided with an arcuate surface 16.1 above, which completely closes and blocks the opening of the locking through-hole 11 of the locking member 4. The outer side end of the arc surface 16.1 is provided with a gradually enlarged convex structure which is made of deformable rubber and gradually protrudes outwards from the midline position of the insert 16. That is, when rod 5 is disposed in locking through-hole 11, insert 16 is inserted into retaining member 4, and when the projection is pressed against rod 5, it is deformed and pressed against rod 5.
