Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a steamed autoclaved aerated concrete board for building construction, its construction equipment and construction method. Background Art

[0002] In the construction field, the autoclaved concrete board, as a common building material, is a porous lightweight board mainly made of cement, lime, sand (or fly ash, slag, etc.), added with a foaming agent, and manufactured through processes such as batching and mixing, casting and forming, pre-curing and cutting, and high-pressure steam curing. It has the advantages of light weight and high strength, heat insulation and sound insulation, fire resistance and earthquake resistance, and convenient construction, and is widely used in building walls, floors, roof panels and other fields. Because of its advantages such as light weight, high strength, and good heat insulation performance, it is widely used in the construction of various building structures.

[0003] However, in the actual construction process, the installation of autoclaved concrete boards faces many challenges. On the one hand, the solid structure of the autoclaved concrete board body leads to excessive self-weight, and during the handling and installation process, construction workers need to consume a lot of physical strength.

[0004] On the other hand, it is difficult to accurately control its position and angle, and installation deviations are likely to occur, affecting the overall quality of the building structure.

[0005] On the other hand, the construction site environment is complex and changeable, and factors such as uneven ground and narrow space increase the difficulty of installing autoclaved concrete boards. Traditional installation methods often cannot meet the requirements of efficient and accurate construction. In view of the above problems, this invention document proposes a steamed autoclaved aerated concrete board for building construction, its construction equipment and construction method. Summary of the Invention

[0006] The present invention provides a steamed autoclaved aerated concrete board for building construction, its construction equipment and construction method, which solves the disadvantages in the prior art that when installing autoclaved concrete boards, it is not convenient to adjust their angles and handle them, and at the same time, the construction method is relatively complex when installing autoclaved concrete boards.

[0007] The present invention provides the following technical solutions:

[0008] A steamed autoclaved aerated concrete board for building construction, including a concrete board,

[0009] Two slots are symmetrically opened at the bottom of the concrete board. The concrete board is a hollow structure, and its interior is filled with a board core. Two steel bar grids are symmetrically embedded in the board core. The slots extend along the bottom surface of the concrete board and penetrate through to its side wall.

[0010] A construction equipment for installing the steamed autoclaved aerated concrete board for building construction according to claim 1, including:

[0011] Rectangular frame, with two first connecting arms rotatably connected to the bottom of one side thereof. The end of the first connecting arm is connected to the first connecting frame through a pin shaft. The bottom of the first connecting frame is fixedly installed with a first support cover. The first support cover is provided with a first spherical groove opening downward. A transmission ball is movably fitted in the first spherical groove. The bottom of the transmission ball protrudes from the first support cover and contacts the ground;

[0012] Support mechanism, including a first cross plate welded between two first connecting frames. The first cross plate is slidably connected to two moving rods. The top of the moving rod is fixedly installed with a mounting frame. A brake disc is provided at the bottom of the mounting frame. A first compression spring is sleeved on the moving rod. The two ends of the first compression spring respectively abut against the mounting frame and the first cross plate;

[0013] Supporting mechanism, including two limiting rings fixed to the top of the rectangular frame. An arc-shaped limiting rod is slidably fitted in the limiting ring. The ends of the two arc-shaped limiting rods are fixedly connected to a support frame. Two docking covers are provided at the bottom of the support frame. The docking cover is in plug-in fit with the slot.

[0014] As a further improvement of the above technical solution:

[0015] Auxiliary support mechanism, including two L-shaped frames. The bottom of the L-shaped frame is inserted into the docking cover. A clamping plate is provided on one side of the L-shaped frame. The clamping plate is connected to a buffer sponge pad through a pressure rod. The buffer sponge pad is fixed in the mounting cover. The mounting cover is welded to the fixing plate of the L-shaped frame.

[0016] Auxiliary balls are provided at the bottom of the support frame. The bottom of the auxiliary balls protrudes from the support frame and contacts the ground; A support shaft is rotatably connected in the rectangular frame. The support shaft is fixedly connected to the support frame through a connecting plate. A torsion spring is sleeved on the support shaft. The two ends of the torsion spring are respectively fixedly connected to the rectangular frame and the connecting plate.

[0017] A moving groove is formed at the bottom of the L-shaped frame. A sliding rod is arranged in the moving groove. A sliding plate is slidably connected to the sliding rod. A clamping shaft is fixed to one side of the sliding plate. A clamping notch for clamping the clamping shaft is formed in the side wall of the docking cover. A second compression spring is sleeved on the sliding rod. Two ends of the second compression spring respectively abut against the sliding plate and the top of the moving groove. A second support cover is arranged at the bottom of the first connecting frame. A support ball is movably embedded in the second support cover. The bottom of the support ball protrudes from the second support cover and contacts the ground. A second cross plate is fixedly connected between the two second support covers. A cross beam is fixed to the top of the support frame. Two handles are arranged on one side of the cross beam. The handles are fixedly connected to the arc-shaped limiting rod through support rods. The rotation angle of the support frame is limited by the sliding stroke of the arc-shaped limiting rod in the limiting ring. The torsion spring provides a restoring moment to keep the support frame horizontal. The rolling directions of the auxiliary balls and the support balls are consistent with the moving direction of the concrete slab.

[0018] A construction method is applied to construction equipment and includes the following steps:

[0019] S1. Clamp the concrete slab onto the docking cover: Insert the concrete slab into the corresponding docking cover through the slot and make it lean against the support frame.

[0020] S2. Rotate the rectangular frame and brake for support: Pull the handle to rotate the rectangular frame towards the construction worker side. At the same time, step on the pedal to drive the mounting frame to move downwards, so that the brake disc contacts the ground, fix the first cross plate and support the first connecting frame.

[0021] S3. Adjust the installation position of the concrete slab: Push the concrete slab to the target area, twist the handle to drive the cross beam to rotate, and adjust the rotation of the support frame around the support shaft through the arc-shaped limiting rod to accurately position the concrete slab.

[0022] S4. Insert the L-shaped frame and fix the concrete slab: Insert the L-shaped frame into the docking cover. After the clamping shaft compresses the second compression spring along the inclined plane, it is clamped into the clamping notch, so that the clamping plate elastically clamps the concrete slab through the buffer sponge pad.

[0023] S5. Move and splice the concrete slab: The construction worker holds the handle or the grip and cooperatively moves the concrete slab. The auxiliary balls assist the sliding of the support frame to complete the splicing and installation of the concrete slab.

[0024] It should be understood that the above general description and the following detailed description are only exemplary and do not limit the present invention.

[0025] Beneficial effects: In the present invention, through the provided support mechanism, when it is necessary to flip the rectangular frame, the pedal can be stepped on downward in advance to drive the two mounting frames to move downward. At this time, the two brake discs can be brought into contact with the ground, so as to stably support the first cross plate, thereby preventing the two first connecting frames from rotating and forming a stable fulcrum, and enabling rotational support for the two first connecting arms when flipping the rectangular frame.

[0026] In the present invention, through the provided supporting mechanism, both hands can hold the two handles and rotate and support the support frame by pushing the cross beam. In this way, after the concrete slab is placed on the two docking covers, the concrete slab can be transported, so that when the concrete slab is installed at the construction site, the position of the concrete slab can be conveniently moved.

[0027] In the present invention, through the provided auxiliary support mechanism, the L-shaped frame is supported by rolling with support balls. In this way, after the L-shaped frame is inserted into the corresponding docking cover, it can assist in pushing the concrete slab to move, so that according to the actual situation at the construction site, when splicing the concrete slab, the position of the concrete slab can be adjusted.

[0028] The present invention can transport the concrete slab and adjust the angle of the concrete slab according to the actual installation position, so as to provide good auxiliary support when installing the concrete slab, making it convenient to install the concrete slab.

Detailed implementation manners

[0042] The embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

[0043] In the description of the embodiments of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "connection" and "installation" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, "communication" can be a direct communication or an indirect communication through an intermediate medium. Among them, "fixing" means that they are connected to each other and the relative positional relationship after connection remains unchanged. The orientation terms mentioned in the embodiments of the present invention, such as "inside", "outside", "top", "bottom", etc., are only references to the direction of the attached drawings. Therefore, the orientation terms used are for better and clearer explanation and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.

[0044] Example 1: Refer to Figure 1-2 , a autoclaved aerated concrete board for building construction. The concrete board 1 is designed as a hollow structure and is filled with a board core 101 inside. The board core 101 is made of a lightweight and high-strength material, such as aerated concrete material, to ensure that the concrete board 1 is both light and strong. Two steel bar grids 103 are symmetrically embedded in the board core 101 to enhance the overall strength and stability of the concrete board 1. Two slots 102 are symmetrically arranged at the bottom of the concrete board 1 for subsequent docking with construction equipment.

[0045] Example 1: Refer to Figure 3-11 , a construction equipment. When the construction equipment is used for installing autoclaved concrete boards, it realizes auxiliary adjustment and support for autoclaved concrete boards, including a rectangular frame 2. Two first connecting arms 201 are installed at the bottom of one side of the rectangular frame 2 by welding, and a first connecting frame 202 is rotatably connected to one end thereof through a pin shaft. The bottom of the first connecting frame 202 is fixedly installed with a first support cover 203 by welding. A first spherical groove is arranged on the first support cover 203, with the opening facing downwards. A driving ball 205 is movably embedded in the first spherical groove. The spherical surface of the driving ball 205 fits with the inner wall of the first spherical groove, and its bottom is located below the first support cover 203 and can contact the ground.

[0046] As Figure 4As shown in the figure, a same support mechanism is installed on the side where the two first connecting frames 202 are close to each other. The support mechanism includes a first horizontal plate 215, and the first horizontal plate 215 is welded to the side where the two first connecting frames 202 are close to each other. Two moving rods 216 are symmetrically and slidably connected through the first horizontal plate 215. The top and bottom ends of the moving rods 216 are fixedly installed with a same mounting frame 217 by welding. A same pedal 219 is installed on one side of the two mounting frames 217 by welding. A brake disc 218 is installed at the bottom of the mounting frame 217 by welding. A first compression spring 220 is sleeved on the moving rod 216 and is located above the first horizontal plate 215. The top and bottom ends of the first compression spring 220 are respectively fixedly connected to the inner wall of the top of the mounting frame 217 and the top of the first horizontal plate 215. When it is necessary to flip the rectangular frame 2, first step on the pedal 219 downward to drive the two mounting frames 217 to move downward, so that the two brake discs 218 are in contact with the ground, thereby stably supporting the first horizontal plate 215 and preventing the two first connecting frames 202 from rotating, forming a stable fulcrum. When flipping the rectangular frame 2, rotate and support the two first connecting arms 201.

[0047] As Figure 6 shown in the figure, a supporting mechanism is installed on one side of the rectangular frame 2. Two docking covers 221 are symmetrically installed on the supporting mechanism. The docking covers 221 pass through the corresponding slots 102 and are used to support the concrete slab 1. The supporting mechanism includes two limiting rings 210 symmetrically and fixedly installed on the top of the rectangular frame 2 by welding. Arc-shaped limiting rods 211 are slidably fitted through both of the two limiting rings 210. One ends of the two arc-shaped limiting rods 211 are fixedly installed with a same supporting frame 208 by welding. Two auxiliary balls 204 are symmetrically and movably embedded at the bottom of the supporting frame 208. The bottom of the auxiliary balls 204 is located below the supporting frame 208 and is used to movably support the supporting frame 208. Two docking covers 221 are symmetrically welded to the bottom of the supporting frame 208, and the concrete slab 1 leans against the supporting frame 208. A support rod 212 is welded to one side of the top of the arc-shaped limiting rod 211. The top ends of the two support rods 212 are welded to a same cross beam 213. Two handles 214 are symmetrically and fixedly connected to one side of the cross beam 213 by bolts. By holding the two handles 214 with both hands and pushing the cross beam 213, the supporting frame 208 can be rotationally supported. In this way, after the concrete slab 1 is placed on the two docking covers 221, the concrete slab 1 can be transported, so that when the concrete slab 1 is installed at the construction site, the position of the concrete slab 1 can be conveniently moved.

[0048] As Figure 5As shown, a support shaft 206 is rotatably connected inside a rectangular frame 2. A circular hole is opened on the top inner wall of the rectangular frame 2. The top end of the support shaft 206 penetrates through the circular hole and extends above the rectangular frame 2. Two connecting plates 207 are sleeved on the support shaft 206 by welding. One side of each of the two connecting plates 207 is welded to a support frame 208. The support shaft 206 can rotatably support the support frame 208, and the central axes of the two arc-shaped limiting rods 211 coincide with the center line of the support shaft 206. A torsion spring 209 is sleeved on the support shaft 206 inside the rectangular frame 2. The top end and the bottom end of the torsion spring 209 are respectively welded to the top inner wall of the rectangular frame 2 and the lower connecting plate 207. The support frame 208 can be rotatably supported by the two connecting plates 207. In this way, when the push handle 214 is pushed, it is convenient to rotate the support frame 208, and the arranged torsion spring 209 can perform rotational elastic limiting on the support frame 208, so that the support frame 208 can be arranged parallel to the rectangular frame 2 under normal conditions.

[0049] As Figure 6 and attached Figure 9 As shown, the auxiliary support mechanism is respectively connected to two docking covers 221 and can clamp the concrete slab 1. The auxiliary support mechanism includes two L-shaped frames 3. The same reinforcing plate 301 is welded to the side of the two L-shaped frames 3 close to each other. A handle 302 is welded to the top of one side of the two L-shaped frames 3, which is convenient for workers to push the auxiliary support mechanism to move. The bottom horizontal area of the L-shaped frame 3 is inserted into the corresponding docking cover 221, and the concrete slab 1 is clamped by cooperating with the support frame 208. A second connecting arm 308 is fixedly installed at the bottom of one side of the L-shaped frame 3. A second connecting frame 309 is rotatably connected to the second connecting arm 308 by a pin shaft. The bottom of the second connecting frame 309 is welded with a second support cover 310. A second spherical groove is arranged on the second support cover 310 and the opening is downward. A support ball 312 is movably embedded in the second spherical groove. The spherical surface of the support ball 312 fits with the inner wall of the second spherical groove. The bottom of the support ball 312 is located below the second support cover 310 and can contact the ground. The same second cross plate 311 is fixedly installed on one side of the two second connecting frames 309 close to each other. The L-shaped frame 3 is supported by rolling through the support ball 312. In this way, after the L-shaped frame 3 is inserted into the corresponding docking cover 221, it can assist in pushing the concrete slab 1 to move, so that the position of the concrete slab 1 can be adjusted when the concrete slab 1 is spliced according to the actual situation of the construction site.

[0050] As Figure 10As shown, it further includes two fixing plates 303 which are respectively arranged above and below the reinforcing plate 301. The two sides of the fixing plate 303 are respectively welded to the closer sides of the two L-shaped frames 3. Two mounting covers 306 are symmetrically welded to one side of the fixing plate 303. A buffer sponge pad 307 is installed in the mounting cover 306 by bonding. One side of the buffer sponge pad 307 is bonded to a pressure rod 304. One end of the pressure rod 304 passes through the fixing plate 303 and the pressure rod 304 is slidably matched with the fixing plate 303. The same clamping plate 305 is fixedly installed at one end of the two pressure rods 304, and the clamping plate 305 can clamp and limit the concrete slab 1. When the two L-shaped frames 3 are respectively inserted and fixed to the two docking covers 221, the two clamping plates 305 can clamp the concrete slab 1, and at the same time, the buffer sponge pad 307 can elastically support the clamping plate 305, so as to elastically support the concrete slab 1, thereby preventing the concrete slab 1 from being damaged by clamping while limiting the concrete slab 1.

[0051] This application can be used in the field of construction technology, and can also be used in other fields applicable to this application.

[0052] Example 3: Refer to Figure 9 , on the basis of Example 1, an improvement is made: A construction device for assisting the autoclaved aerated concrete slab in building construction, which is applied to the field of construction technology. A moving groove 313 is opened at the bottom of one side of the L-shaped frame 3. A sliding rod 314 is welded in the moving groove 313. A sliding plate 315 that can slide is sleeved on the sliding rod 314. A clamping shaft 316 is welded to one side of the sliding plate 315. A clamping opening 222 is opened on the inner wall of one side of the docking cover 221, and the clamping shaft 316 is clamped with the inner wall of the clamping opening 222. A second compression spring 317 sleeved on the sliding rod 314 is also welded above the sliding plate 315, and the top end of the second compression spring 317 is welded to the inner wall of the top of the moving groove 313. When the L-shaped frame 3 is inserted into the corresponding docking cover 221, the clamping shaft 316 can move upward along the opening inclined surface of the docking cover 221. At this time, the sliding plate 315 can be driven to move upward, compressing the second compression spring 317. When the clamping shaft 316 moves to a position corresponding to the clamping opening 222, the second compression spring 317 in the stressed state can push the sliding plate 315 downward, so that the clamping shaft 316 is stably clamped with the clamping opening 222, thereby enabling the L-shaped frame 3 to be stably connected to the docking cover 221.

[0053] The present invention proposes a construction method, which is applied to the construction device as described above, and includes the following steps:

[0054] S1. First, the concrete slab 1 is clamped on the corresponding docking cover 221 through the two slots 102, and the concrete slab 1 is leaned against the support frame 208;

[0055] S2. Rotate the rectangular frame 2 towards the side of the construction worker by pulling the two handles 214. Synchronously, step on the pedal 219 downward in advance to drive the two mounting brackets 217 to move downward. At this time, the two brake discs 218 can be made to contact the ground, so as to stably support the first cross plate 215, thereby preventing the two first connecting frames 202 from rotating, forming a stable fulcrum, and being able to rotationally support the two first connecting arms 201 when the rectangular frame 2 is flipped;

[0056] S3. Push the concrete slab 1 to the area in the building where it needs to be installed, and drive the cross beam 213 to rotate by twisting the two handles 214. At this time, the two arc-shaped limiting rods 211 can drive the support frame 208 to rotate and adjust around the support shaft 206, so as to adjust the position of the concrete slab 1 according to the on-site construction conditions until the concrete slab 1 is moved to the installation position;

[0057] S4. When inserting the L-shaped frame 3 into the corresponding docking cover 221, the clamping shaft 316 can move upward along the opening inclined surface of the docking cover 221. At this time, it can drive the slide plate 315 to move upward and compress the second compression spring 317. When the clamping shaft 316 moves to a position corresponding to the bayonet 222, the second compression spring 317 in the stressed state can push the slide plate 315 downward to stably clamp the clamping shaft 316 with the bayonet 222, so as to stably connect the L-shaped frame 3 with the docking cover 221. And when the two L-shaped frames 3 are respectively inserted and fixed with the two docking covers 221, the two clamping plates 305 can clamp the concrete slab 1, and at the same time, the buffer sponge pad 307 can elastically support the clamping plates 305, so as to elastically support the concrete slab 1, thereby being able to prevent the concrete slab 1 from being damaged by clamping while limiting the concrete slab 1;

[0058] S5. The construction workers on both sides of the concrete slab 1 can respectively hold the two handles 214 or the handles 302 and cooperate with each other to move the concrete slab 1 to be installed, so as to splice and install the concrete slab 1. And for the support frame 208 in the vertical position, the two auxiliary balls 204 provided at the bottom can support the support frame 208, thereby facilitating the movement of the concrete slab 1.
