Description

Technical Field

[0001] The invention relates to the technical field of assembled building engineering, in particular to a prefabricated assembled steel-wood combined structure and an assembly method thereof. Background Art

[0002] Prefabricated steel-wood composite structure is a modern building structure that combines the advantages of steel and wood to improve building performance and reduce construction costs. It is assembled on site through prefabricated steel and wood components in the factory, thereby achieving rapid construction, load sharing and structural stability.

[0003] During the installation of signs or curtain walls, it is necessary to build a bracket to install the signs, and the installation of the bracket requires a prefabricated structure. If the bracket is a steel structure as a whole, its gravity is large and there is a risk of falling when hanging. If a wooden structure is used, its structural rigidity is insufficient and it will be damaged by wind and external forces. Then the bracket will shake under the action of wind, affecting the normal use of the sign or curtain wall.

[0004] In order to solve the above problems, a variety of solutions have been proposed in the prior art, such as the curtain wall with patent number 201410115549.5. The curtain wall panel falls onto the displacement drive device under its own weight. Due to the gravity of the curtain wall panel, the displacement drive device will drive the pressure plate to move toward the curtain wall panel to eliminate the gap between the pressure plate and the curtain wall panel. When the curtain wall panel further falls, the displacement drive device will further drive the pressure plate to drive the curtain wall panel to move toward the keel to eliminate the gap between the curtain wall panel and the keel, thereby realizing secondary clamping and fastening of the curtain wall panel. Although this method realizes secondary fixation of the curtain wall panel, the curtain wall has undergone relative displacement at this time, and it is impossible to take into account the vertical load affected by gravity and the wind load affected by wind force.

[0005] Based on this, in order to solve the problem that it is difficult to take into account both the longitudinal load caused by gravity and the lateral load caused by wind when installing signs or curtain walls at high altitudes, which in turn causes the signs or curtain walls to shake, thereby reducing the load capacity of the signs or curtain walls, the present invention designs a prefabricated steel-wood combination structure and its assembly method. Summary of the invention

[0006] The present invention provides a prefabricated assembled steel-wood combination structure and an assembly method thereof, in order to solve the problem that it is difficult to take into account both the vertical load and the wind load when installing signs or curtain walls at high altitudes, which causes the signs or curtain walls to shake, thereby reducing the load capacity of the signs or curtain walls. Through the assembled steel-wood structure, the firmness and stability of steel and the lightness and thermal insulation of wood are utilized, and the stability of shear walls and triangles is simultaneously adopted, thereby improving the stability of the high-altitude signs after installation.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] The present invention provides a prefabricated steel-wood combination structure, comprising an outer rod, a support rod, a bottom plate, a support mechanism, a slide groove, a wedge block, a push rod, a hinged rod, a stabilizing mechanism and a movable plate, wherein the outer rod is spliced, the support rod is located below the spliced ​​outer rod, the outer rod and the support rod form a closed loop, the top of the support rod is used to install a sign, the bottom plate is installed between the outer rod and the support rod, the support mechanism is installed on the bottom plate, the slide groove is opened on the support rod, the wedge block slides in the slide groove, the push rod is installed on the wedge block, one end of the hinged rod is installed on the top of the rear side of the sign, the other end of the hinged rod is in contact with the push rod, the stabilizing mechanism is installed above the support rod, and the movable plate is On the front side of the base plate, when the sign is installed, the wedge block drives the push rod to move to both sides, and the push rod supports the outer rod through the hinge rod, and the support mechanism locks the hinge rod. When the sign contacts the stabilizing mechanism, the stabilizing mechanism drives the movable plate to move forward to fix the hinge rod and lock the sign synchronously. When the sign squeezes the wedge block, the wedge block squeezes the hinge rod through the push rod. At this time, the hinge rod gradually rotates around the hinge point, thereby driving the stabilizing mechanism to work normally, thereby fixing the sign and the outer rod; and in the process of the sign continuing to descend, it will drive the movable plate to move through the stabilizing mechanism. When the movable plate moves, it will approach the sign, thereby playing a supporting role. At the same time, the movable plate can constrain the longitudinal position of the sign, thereby playing a fixing role.

[0009] Preferably, the supporting mechanism includes a limit slot, an insert block, a clamping slot, a triangular block, and a compression spring. The limit slot is provided on the side wall of the outer rod, the insert block is installed on the free end of the hinged rod, the clamping slot is provided inside the insert block, the triangular block is installed in the clamping slot, and the compression spring is installed between the triangular block and the insert block, so that the sign and the outer rod are locked with each other, thereby improving the fixing effect of the sign.

[0010] Preferably, an inclined groove is provided on the top of the movable plate, the cross-sectional area of ​​the inclined groove is larger than the cross-sectional area of ​​the hinged rod, and the side walls of the inclined groove and the hinged rod are smooth arc surfaces, so that the internal structure of the outer rod forms a mesh structure, thereby improving the stability of the outer rod frame.

[0011] Preferably, the stabilizing mechanism includes a driving chamber, a top block, a sliding rod, and a card plate. The driving chamber is opened at the center of the support rod, the top block slides in the driving chamber, the sliding rod is installed in the driving chamber, one end of the sliding rod is in contact with the top block, and the card plate is installed at the other end of the sliding rod. The card plate is located behind the movable plate. On the one hand, the movable plate supports and limits the sign, and on the other hand, a vacuum layer is formed to improve the thermal insulation and stability of the device.

[0012] Preferably, the wedge block is replaceable, and the angle between the wedge block and the horizontal plane is between 30° and 60°, thereby being able to adapt to signs or curtain walls of different widths.

[0013] Preferably, a circular groove is provided on the back of the sign, and a protrusion is installed on the movable plate facing the side of the sign, thereby limiting the longitudinal position of the sign and improving the fixing effect of the sign.

[0014] Preferably, the angle between the hinged rod and the horizontal plane is 45°, and buttresses are installed on the back of the base plate to increase the wind load and enhance the wind resistance of the device.

[0015] Preferably, the top ends of the two hinged rods fit together and are located at the midpoint of the outer rod, and the hinged rods are used to form a mesh support for the inside of the outer rod, thereby improving the wind resistance and stability of the structure.

[0016] Preferably, a sealing hole is opened on the bottom plate, and a limiting rod is installed on the back of the movable plate. The limiting rod is sealingly and slidingly connected to the sealing hole to limit the sliding trajectory of the movable plate. The limiting rod synchronously forms a horizontal mesh structure inside to improve wind resistance and structural strength.

[0017] A method for assembling a prefabricated steel-wood composite structure, which is applicable to the assembly of any of the above-mentioned prefabricated steel-wood composite structures, firstly, the outer rod and the support rod are surrounded by screws to form a closed ring, the outer rod and the support rod are fixed on the wall to form a base, and then the bottom plate and the movable plate are sequentially installed inside the outer rod and the support rod;

[0018] Secondly, insert the sign into the cavity formed by the outer rod and the support rod. The sign will first squeeze the wedge block, and then the wedge block will drive the push rod to squeeze the hinged rod on the back of the sign. The hinged rod on the back of the sign is embedded in the outer rod, thereby forming a secondary fixation for the outer rod.

[0019] Finally, the sign is driven down again to squeeze the top block, which will drive the card plate to move through the sliding rod. The card plate moves forward and drives the movable plate to move forward. At this time, a vacuum layer is formed between the movable plate and the bottom plate. At the same time, the protrusion on the movable plate is embedded in the sign to fix it. At the same time, the hinged rod is embedded in the movable plate to form a snap fit.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The present invention proposes a prefabricated assembled steel-wood combination structure. When the sign squeezes the wedge block, the wedge block squeezes the hinge rod through the push rod. At this time, the hinge rod gradually rotates around the hinge point, thereby driving the stabilizing mechanism to work normally, thereby fixing the sign and the outer rod; and in the process of the sign continuing to descend, it will drive the movable plate to move through the stabilizing mechanism. When the movable plate moves, it will get closer to the sign, on the one hand to achieve support, and on the other hand the movable plate can constrain the longitudinal position of the sign, thereby achieving fixation; further, the movable plate and the bottom plate are relatively sealed. At this time, the movement of the movable plate constructs a relative vacuum layer, thereby improving the stability of the sign after installation.

[0022] 2. The present invention proposes a prefabricated assembled steel-wood combination structure. During the downward movement of the sign, the insert block also moves downward. After the hinged rod contacts the push rod, the push rod drives the hinged block to rotate around the hinge point. The insert block gradually approaches the outer rod on the side. Subsequently, under the further push of the push rod, the insert block moves into the limit groove. The triangular block on the insert block is squeezed by the limit groove and moves into the slot, thereby squeezing the compression spring. When the tail end of the triangular block completely enters the limit groove, the triangular block is reset under the influence of the compression spring and is blocked in the limit groove. At this time, the position of the sign is fixed by the cooperation of the outer rod and the insert block. At the same time, the hinged rod can strengthen the internal support, thereby improving the stability of the outer rod itself and between the outer rod and the sign.

[0023] 3. The present invention proposes a prefabricated assembled steel-wood combination structure. As the sign continues to slide downward, the top block will be pushed downward, and the bottom of the top block will cooperate with the sliding rod wedge shape, which will naturally drive the sliding rod to move forward along the driving cavity. The sliding rod will then drive the card plate to move forward. The initial position of the card plate is between the movable plate and the bottom plate. A certain groove can be opened on the bottom plate for the placement of the card plate. As the card plate pushes the movable plate to move, the space between the movable plate and the bottom plate is gradually stretched. When the two are sealed, a relative vacuum will be formed, thereby improving the stability of various performances after the installation of the sign. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] In order to better understand the above solution, the above technical solution is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] like Figure 1-3 As shown, the present invention provides a prefabricated steel-wood combination structure, including an outer rod 1, a support rod 2, a bottom plate 3, a support mechanism 4, a slide 5, a wedge block 6, a push rod 7, a hinge rod 8, a stabilizing mechanism 9 and a movable plate 10. The outer rod 1 is spliced, and there are slight differences in the structure between the outer rods 1. The top outer rod 1 and the outer rods 1 on both sides are different in shape and size, but the function of both is to form a frame. A notch can be provided on the upper outer rod 1, which is convenient for inserting a sign 11. The support rod 2 and the outer rod 1 are both made of steel, while the bottom plate 3 and the movable plate 10 are made of wood.

[0036] The support rod 2 is located below the spliced ​​outer rod 1. The support rod 2 can be provided with some notches for the sign 11. The length of the sign 11 cannot be greater than the length of the upper outer rod 1, and the height is preferably not higher than the height of the side outer rod 1, to ensure that the sign 11 can be completely wrapped by the outer rod 1 and the support rod 2; the outer rod 1 and the support rod 2 form a closed loop, and then form a frame-type wrapping, which can constrain the sign 11 to be installed between the outer rod 1 and the support rod 2;

[0037] The bottom plate 3 is installed between the outer rod 1 and the support rod 2. The bottom plate 3 not only supports but also facilitates the overall installation arrangement. Here, the outer rod 1 and the support rod 2 can be a structure with a high outside and a low inside, so that the outer rod 1 and the support rod 2 can also constrain the bottom plate 3 and the sign 11 in the front and rear directions; the support mechanism 4 is installed on the bottom plate 3, and the support mechanism 4 is used to limit the sign 11 and simultaneously fix the sign 11 on the outer rod 1 and the support rod 2, thereby achieving a fixing effect;

[0038] The slide groove 5 is provided on the support rod 2, and the wedge block 6 is located in the slide groove 5 and slides. The wedge block 6 is pushed by the bottom of the sign 11 and is displaced laterally. In the process of the sign 11 gradually descending, the sign 11 drives the wedge block 6 to move to a position away from the center. Then the wedge block 6 is squeezed and deformed by the return spring arranged inside. The wedge block 6 synchronously drives the push rod 7 connected thereto to move away from the center. One end of the hinged rod 8 is installed on the top of the rear side of the sign 11, and the other end of the hinged rod 8 is in contact with the push rod 7. At this time, the initial position of the hinged rod 8 is set to an inclined state to ensure that the hinged rod 8 can contact the push rod 7 when the sign 11 descends. When the sign 11 squeezes the wedge block 6, the wedge block 6 squeezes the hinged rod 8 through the push rod 7. At this time, the hinged rod 8 gradually rotates around the hinge point, thereby driving the stabilizing mechanism 9 to work normally, thereby fixing the sign 11 and the outer rod 1; and in the process of the sign 11 continuing to descend, it will drive the movable plate 10 to move through the stabilizing mechanism 9. When the movable plate 10 moves, it will get closer to the sign 11, thereby playing a supporting role. At the same time, the movable plate 10 can constrain the longitudinal position of the sign 11, thereby playing a fixing role; further, the movable plate 10 and the bottom plate 3 are relatively sealed. At this time, the movement of the movable plate 10 is equivalent to building a relative vacuum layer, and the heat insulation and sound insulation of the vacuum environment are better than those of wood materials, thereby realizing the combination of steel structure, wood structure and vacuum layer, thereby improving the stability of the sign 11 after installation.

[0039] The movable plate 10 is located on the front side of the base plate 3. When the sign 11 is installed, the wedge block 6 drives the push rod 7 to move to both sides. The push rod 7 supports the outer rod 1 through the hinge rod 8. The supporting mechanism 4 locks the hinge rod 8. When the sign 11 contacts the stabilizing mechanism 9, the stabilizing mechanism 9 drives the movable plate 10 to move forward to fix the hinge rod 8, and synchronously locks the sign 11.

[0040] In addition, the hinged rod 8 forms a triangle with the outer rod 1 on the side and the outer rod 1 on the top respectively, and the triangle has a certain stability, thereby improving the structural strength.

[0041] like Figure 4As shown, the support mechanism 4 includes a limit groove 41, an insert block 42, a slot 43, a triangular block 44, and a compression spring 45. The limit groove 41 is provided on the side wall of the outer rod 1, the insert block 42 is installed at the free end of the hinge rod 8, the slot 43 is provided inside the insert block 42, the triangular block 44 is installed in the slot 43, and the compression spring 45 is installed between the triangular block 44 and the insert block 42. When the sign 11 moves downward, the insert block 42 also moves downward. After the hinge rod 8 contacts the push rod 7, the push rod 7 drives the hinge block to rotate around the hinge. The joint rotates, and the insert block 42 will gradually approach the outer rod 1 on the side. There are two situations here. One is that the distance that the push rod 7 pushes the hinged rod 8 upward is less than the distance that the sign 11 moves downward. In this case, the insert block 42 gradually moves downward to the limit groove 41. The other is that the distance that the push rod 7 pushes the hinged rod 8 upward is greater than the distance that the sign 11 moves downward. In this case, the insert block 42 has crossed the limit groove 41 when the sign 11 descends. Under the action of the push rod 7, the hinged rod 8 rotates around the hinge point, and the insert block 42 moves upward, and then gradually approaches the limit groove 41.

[0042] Then, under the further push of the push rod 7, the plug block 42 moves into the limiting groove 41, and the triangular block 44 on the plug block 42 is squeezed by the limiting groove 41 and moves into the card groove 43, thereby squeezing the compression spring 45. When the tail end of the triangular block 44 completely enters the limiting groove 41, the triangular block 44 is reset under the influence of the compression spring 45 and then blocked in the limiting groove 41. At this time, the position of the sign 11 is fixed. At the same time, the position of the hinge rod 8 is also fixed, and the hinge rod 8 is connected to the sign 11. The top of the movable plate 10 is provided with an inclined groove 101, and the cross-sectional area of ​​the inclined groove 101 is larger than the cross-sectional area of ​​the hinge rod 8. The side walls of the inclined groove 101 and the hinge rod 8 are smooth arc surfaces; at this time, the inclined surface of the movable plate 10 The groove 101 also wraps around the hinged rod 8. The inclined groove 101 is much larger than the hinged rod 8. Otherwise, when the sign 11 just starts to drive the movable plate 10 to move, the hinged rod 8 is not completely fixed. If the inclined groove 101 is equal to the cross-sectional area of ​​the hinged rod 8, the two will interfere with each other. Therefore, the cross-sectional area of ​​the inclined groove 101 is set larger than the cross-sectional area of ​​the hinged rod 8, so that the hinged rod 8 can be trapped in the inclined groove 101. The inclined groove 101 is opened on the movable plate 10, and the movable plate 10 is constrained by the upper and side wall outer rods 1. Therefore, the hinged rod 8 can support the side outer rod 1 and the upper outer rod 1 (although the outer rods 1 have been fixed by screws and other existing technologies, adding the hinged rod 8 can improve the internal strength).

[0043] like Figure 5As shown, the stabilizing mechanism 9 includes a driving chamber 91, a top block 92, a slide bar 93, and a card plate 94. The driving chamber 91 is opened at the center of the support rod 2. The top block 92 slides in the driving chamber 91. The slide bar 93 is installed in the driving chamber 91. One end of the slide bar 93 contacts the top block 92. The card plate 94 is installed at the other end of the slide bar 93. The card plate 94 is located behind the movable plate 10. When the sign 11 continues to slide downward, it will push the top block 92 to move downward, and the bottom of the top block 92 The wedge-shaped cooperation with the slide bar 93 will naturally drive the slide bar 93 to move forward along the driving cavity 91. The slide bar 93 will drive the card plate 94 to move forward at this time. The initial position of the card plate 94 is between the movable plate 10 and the bottom plate 3. A certain groove can be opened on the bottom plate 3 for the placement of the card plate 94. In the process of the card plate 94 pushing the movable plate 10 to move, the movable plate 10 and the bottom plate 3 are gradually stretched. When the two are sealed, a relative vacuum will be formed, thereby improving the stability of various performances of the sign 11 after installation.

[0044] The wedge block 6 is replaceable, and the angle between the wedge block 6 and the horizontal plane is between 30° and 60°. The staff can select the appropriate wedge block 6 according to the width of the sign 11. The specific value can be calculated. When the width of the sign 11 is wide, the distance of lateral movement will be relatively large. Therefore, a wedge block 6 with a large angle with the horizontal plane is set, which can reduce the space for the wedge block 6 to move, and at the same time increase the time for the push rod 7 to push the hinge rod 8 to embed into the limit groove 41, thereby forming a quick fix. The sign 11 can be set to be located in the wedge block 6, that is, the wedge block 6 is provided with a groove for placing the corner of the sign 11; at the same time, a baffle (such as Figure 1 ), thereby preventing the sign 11 from tilting forward.

[0045] like Figure 6-7 As shown, a circular groove 111 is provided on the back of the sign 11, and a protrusion 12 is installed on the side of the movable plate 10 facing the sign 11. When the movable plate 10 moves toward the sign 11, on the one hand, a vacuum layer is formed between the movable plate 10 and the bottom plate 3, thereby isolating heat and sound. On the other hand, the protrusion 12 on the surface of the movable plate 10 can cooperate with the circular groove 111 to limit the longitudinal relative position of the sign 11. A little gap can be left between the protrusion 12 and the circular groove 111 to compensate for the distance that the sign 11 is still moving longitudinally when the movable plate 10 moves horizontally. The material of the protrusion 12 can also be limited to hard rubber. At this time, there can be a certain distance buffer compensation, and the rigid contact between the two is reduced, thereby improving the stability of the structure.

[0046] The angle between the hinged rod 8 and the horizontal plane is 45°, and a buttress column 31 is installed on the back of the base plate 3. After the hinged rod 8 is installed, the angle between the hinged rod 8 and the horizontal plane is 45°, which is equivalent to constraining the outer rod 1 on the side and the outer rod 1 on the top (limited by the inclined groove 101 on the movable plate 10). On this basis, a woven inner net can be formed, and the buttress column 31 is used to form a "shear wall" in the overall structure. The shear wall can achieve wind resistance, and then when the wind blows directly towards the sign 11, the annular structure formed by the outer rod 1 and the support rod 2, the "semi-net" structure formed by the hinged rod 8 and the buttress column 31 on the base plate 3 can be used to increase the wind load, thereby preventing the sign 11 from shaking due to excessive wind.

[0047] The top ends of the two hinged rods 8 fit together and are located at the midpoint of the outer rod 1. The top end of the hinged rod 8 is set at the center position of the top outer rod 1. At this time, after the sign 11 is installed, the hinged rod 8 becomes a supporting carrier for the side outer rod 1 and the upper outer rod 1, thereby improving the internal stability of the mechanism composed of the outer rod 1.

[0048] A sealing hole 32 is provided on the bottom plate 3, and a limiting rod 102 is installed on the back of the movable plate 10. The limiting rod 102 is sealingly and slidably connected with the sealing hole 32. In order to prevent the movable plate 10 from moving only at the bottom when the clamping plate 94 moves (because a relative vacuum needs to be formed there, a relatively large force is required, and if the movable plate 10 is not restricted, the movable plate 10 may be folded, thereby destroying the overall structure), a sealing hole 32 and a limiting rod 102 are provided there to cooperate, thereby guiding the movement of the movable plate 10 and further forming a mesh structure to support the overall structure.

[0049] like Figure 8 As shown, a method for assembling a prefabricated steel-wood composite structure is applicable to the assembly of any of the above-mentioned prefabricated steel-wood composite structures. First, the outer rod 1 and the support rod 2 are surrounded by screws to form a closed ring, and the outer rod 1 and the support rod 2 are fixed on the wall to form a base. Then, the bottom plate 3 and the movable plate 10 are installed inside the outer rod 1 and the support rod 2 in sequence.

[0050] Secondly, insert the sign 11 into the cavity formed by the outer rod 1 and the support rod 2. The sign 11 will first squeeze the wedge block 6. At this time, the wedge block 6 will drive the push rod 7 to squeeze the hinge rod 8 on the back of the sign 11. The hinge rod 8 on the back of the sign 11 is embedded in the outer rod 1, thereby forming a secondary fixation for the outer rod 1.

[0051] Finally, the sign 11 is driven downward again to squeeze the top block 92, and the top block 92 drives the card plate 94 to move through the slide bar 93. The card plate 94 moves forward to drive the movable plate 10 to move forward. At this time, a vacuum layer is formed between the movable plate 10 and the bottom plate 3. At the same time, the protrusion 12 on the movable plate 10 is embedded in the sign 11 to form a fixation. At the same time, the hinged rod 8 is embedded in the movable plate 10 to form a snap fit.

[0052] When it is necessary to install the sign 11 at high altitude, first install the prefabricated bracket, form an annular frame through the steel outer rod 1 and the support rod 2, put the bottom plate 3 and the movable plate 10 into the ring formed by the outer rod 1 and the support rod 2 in turn, and then fix them on the wall by screws and the like, insert the sign 11, and the sign 11 moves downward and gradually contacts the wedge block 6. The wedge block 6 slides in the slide groove 5, and the synchronous wedge block 6 also drives the push rod 7 to squeeze the hinge rod 8. Under the action of the supporting mechanism 4, the hinge rod 8 gradually embeds the hinge rod 8 in the outer rod 1, thereby fixing the sign 11. In the process of the sign 11 continuing to move downward, it will squeeze the stabilizing mechanism 9. The stabilizing mechanism 9 drives the movable plate 10 away from the bottom plate 3, and the movable plate 10 approaches the sign 11. On the one hand, it supports the sign 11, and on the other hand, a relative vacuum layer is formed between the movable plate 10 and the bottom plate 3, thereby improving the stability of the overall structure.

[0053] Specifically, when the sign 11 moves downward along the outer rod 1, it will drive the wedge block 6 to slide along the slide groove 5. At this time, the insert block 42 gradually approaches the limit groove 41. When the insert block 42 fits the limit groove 41, under the action of the push rod 7, the front end of the insert block 42 will first enter the limit groove 41. Under the restriction of the limit groove 41, the triangular block 44 will squeeze the compression spring 45 and enter the card slot 43. When the triangular block 44 completely enters the limit groove 41, the restriction of the compression spring 45 will contact, thereby driving the triangular block 44 to be stuck on the outer rod 1, thereby forming a fixation of the sign 11 and the bracket of the outer rod 1; due to the insertion block 42 and the hinge block It is also hinged, and the sign 11 can continue to move downward at this time, but it is best that the sign 11 continues to move downward when the triangular block 44 is not released, until the triangular block 44 is released when it moves to the bottom of the support rod 2, thereby forming a lock. In this process, the sign 11 will squeeze the top block 92 in the drive cavity 91 to move downward, and the lower end of the top block 92 is wedge-fitted with the slide bar 93, thereby driving the slide bar 93 to move forward, and synchronously driving the card plate 94 to move forward. The card plate 94 will push the movable plate 10 to move away from the bottom plate 3, thereby further fixing the sign 11, and also using the vacuum layer to improve the overall stability.
