Description

Technical Field

[0001] The present application relates to the technical field of prefabricated building walls, and in particular to a prefabricated building wall structure. Background Art

[0002] With the progress of urbanization, more and more high-rise buildings are springing up. In traditional engineering construction, brick walls are used on site for construction. This construction method has a long construction period and high cost. In order to solve this problem, modular design is adopted. Prefabricated building walls, floor slabs, stair parts and various engineering parts are installed by hoisting. The construction task can be completed in a short time, which greatly shortens the construction period and reduces the cost.

[0003] When installing the building wall, the tower crane driver will lift the building wall to the predetermined position by hoisting, and then manually align the fixing holes at the bottom of the building wall with the positioning steel bars, and then lower it. Then the workers use fixing rods to connect and fix the building wall and the floor slab, and inject concrete into the fixing holes. After it solidifies, the lifting cable is released to hoist the next building wall. This type of building wall structure and installation method is the most widely used one at present, with the advantages of simple structure, easy operation and low cost.

[0004] Although the existing building wall structure has many advantages as mentioned above, it still has certain limitations in actual use. In order to ensure that the mortar can be completely injected into the interior of the fixing hole without retaining air, through holes are opened at the top and bottom of the fixing hole. Before injection, the through hole at the top is blocked with a wooden plug, and then the concrete is injected through the through hole at the bottom. This will cause a large amount of concrete to flow out of the through hole at the top, causing waste. In addition, multiple through holes will cause the local structural strength to be weakened, which may easily cause the risk of structural breakage. In this regard, the present application document proposes an assembled building wall structure to solve the above-mentioned problems. Summary of the invention

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: an assembled building wall structure, including a floor slab, a connecting shaft seat is fixedly installed on the top of the floor slab near the front by means of bolt connection, a positioning steel bar is fixedly sleeved on the top of the floor slab near the back by means of sleeve setting, a wall device is fixedly installed on the top of the floor slab near the back by means of connection with the positioning steel bars, a connecting device is fixedly installed on one side of the wall device by means of snap connection, a fixed shaft seat is fixedly installed on the front of the floor slab near the top by means of bolt connection, a fixing rod is movably sleeved on one side of the connecting shaft seat by means of shaft hole cooperation, and one end of the fixing rod is engaged with the fixing shaft seat by means of shaft hole cooperation.

[0006] Furthermore, the wall device includes a wall panel, wherein longitudinal structural steel bars are fixedly sleeved on the inner sides of the wall panel by means of sleeves, the longitudinal structural steel bars penetrate the top of the wall panel, and the longitudinal structural steel bars are distributed in an array manner; transverse structural steel bars are fixedly sleeved on the inner sides of the wall panel by means of sleeves, and the transverse structural steel bars penetrate both sides of the wall panel; fixing holes are provided on the bottom of the wall panel near both sides by means of integral forming, the fixing holes are distributed in the form of a rectangular array, and the axes of the fixing holes correspond one to one with the axes of the longitudinal structural steel bars; connecting holes are provided on the top of the fixing holes by means of integral forming, and the connecting holes are in a connected state with the fixing holes; slurry discharge holes are opened on the inner sides of the wall panel near the bottom by means of integral forming; grouting holes are opened on the front side of the wall panel near the bottom by means of integral forming, and the grouting holes are close to both sides of the wall panel and connected with the fixing holes.

[0007] Furthermore, the fixing holes and the positioning steel bars are in a one-to-one correspondence.

[0008] Furthermore, the connecting device includes a connecting plate, and correction grooves are opened on the front side of the connecting plate near the two sides by means of a milling machine. The correction grooves are distributed in a linear array from top to bottom. Thinning grooves are opened on the front side of the connecting plate at the two sides of the midline. The thinning grooves extend from the top of the connecting plate to the bottom of the connecting plate, and the thinning grooves are connected to the correction grooves.

[0009] Furthermore, the correction grooves correspond one-to-one to the transverse structural steel bars.

[0010] Furthermore, the connecting device is made of wood.

[0011] Furthermore, after the connection device is installed, it forms a cavity with a top opening with the wall panels on both sides, and the slurry discharge hole is connected to the cavity.

[0012] This application has the following beneficial effects.

[0013] 1. Fixing holes are provided at the bottom of the wall panel near both sides by integral forming, and the fixing holes are distributed in a rectangular array. The axes of the fixing holes correspond to the axes of the longitudinal structural steel bars one by one. The tops of the fixing holes are provided with connecting holes by integral forming, and the connecting holes and the fixing holes are in a connected state. Grouting holes are provided at the front of the wall panel near the bottom by integral forming, and the grouting holes are close to both sides of the wall panel and connected to the fixing holes. When concrete is injected into the interior for fixing, concrete is injected into the interior of the fixing holes through the grouting holes. Since the connecting holes are in a connected state with each fixing hole, the concrete can In order to fill each fixed hole through the connecting hole, in the traditional equipment, through holes need to be opened near the bottom and the top of the fixed hole, and the concrete is injected through the through holes. In order to ensure that the fixed holes can be filled with concrete, the pressure must be increased during the filling process. Although the operator will use a wooden plug to block the upper through hole during the filling process, a large amount of concrete will still flow out from the gap between the upper through hole and the wooden plug, causing waste. In addition, due to the existence of multiple sets of fixed holes, the filling operation needs to be repeated many times, resulting in a long time for the entire filling operation and complicated operation. The present application document avoids these problems well and improves the reliability of the device.

[0014] 2. The device involved in the present application mainly needs to open a single injection hole, which reduces the difficulty of manufacturing the device, while reducing the number of openings on the front of the wall panel, improving the structural strength of the connection between the bottom of the wall panel and the positioning steel bars, and avoiding the problem of damage to the fixing holes during the fixing process due to the decrease in structural strength due to the presence of multiple holes, thereby improving the structural strength of the device.

[0015] 3. By making the correction groove correspond to the transverse structural steel bars one by one, the position of the transverse structural steel bars can be adjusted through the correction groove during the installation of the connecting plate, so that the transverse structural steel bars can be kept inside the correction groove, thereby achieving the fixing effect on the connecting plate. In the subsequent installation operation, the wall device and the connecting device can be continuously installed again through the same principle, so that after the first wall device is installed and fixed, the subsequent wall devices can be preliminarily fixed through the connecting effect of the connecting device. This installation method allows the tower crane to disconnect the lifting connection with the wall device after the lifting is completed and the wall device is connected to the connecting device. At this time, the operator can fix the wall device by installing the fixing rod, and in this process, the tower crane can lift the subsequent wall devices, thereby achieving the effect of accelerating the construction progress and improving the practicality of the device.

[0016] 4. After the connection device is installed, it forms a cavity with a top opening with the wall panels on both sides, and the slurry discharge hole is connected to the cavity. When the device is fixed by injecting concrete through the grouting hole, the excess concrete will overflow through the slurry discharge hole and enter the cavity with a top opening formed with the wall panels on both sides after the connection device is installed, and the height of the concrete inside the cavity continues to increase until the interior of the cavity is filled, and the pressure generated inside the fixing hole continues to increase, thereby achieving the effect of compacting the concrete inside the fixing hole, improving the firmness of the fixing hole and the positioning steel bar, and improving the firmness of the connection of the device. In addition, after the connection device is installed, after the concrete in the cavity with a top opening formed with the wall panels on both sides solidifies, a concrete column connecting the wall devices on both sides will be formed, and the concrete column can preliminarily fill the gap between the wall devices and further reinforce the structure of the wall devices, thereby reducing the risk of the wall devices tipping over and improving the safety performance of the device.

[0017] 5. Thinning grooves are provided on the front of the connecting plate on both sides of the center line, so that the thinning grooves divide the connecting plate into three parts, and the structure at the thinning grooves is relatively fragile. After the concrete is completely solidified, the part of the connecting plate located between the thinning grooves can be removed through the thinning grooves. After the removal, a space is generated in the middle, and the remaining parts on both sides are pulled out and removed, thereby realizing the rapid removal of the connecting device. After the connecting device is removed, since the previous transverse structural steel bars corresponded to the correction grooves one by one, and the connecting device has a tendency to move outward under the pressure of the concrete, further squeezing pressure is generated on the transverse structural steel bars, and the position of the transverse structural steel bars is corrected to ensure the correct position of the transverse structural steel bars, which provides convenience for the subsequent production of the steel cage and further improves the practicality of the device.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] A prefabricated building wall structure, see Figure 1-Figure 2 , including a floor 1, a connecting shaft seat 2 is fixedly installed at the top of the floor 1 near the front by means of bolt connection, a positioning steel bar 3 is fixedly sleeved at the top of the floor 1 near the back by means of sleeve setting, a wall device 4 is fixedly installed at the top of the floor 1 near the back by means of connection with the positioning steel bar 3, a connecting device 5 is fixedly installed at one side of the wall device 4 by means of clip connection, a fixed shaft seat 6 is fixedly installed at the front of the floor 1 near the top by means of bolt connection, a fixing rod 7 is movably sleeved at one side of the connecting shaft seat 2 by means of shaft hole matching, and one end of the fixing rod 7 is matched with the fixed shaft seat 6 by means of shaft hole matching.

[0032] See also Figure 1-Figure 7The wall device 4 includes a wall panel 41, and longitudinal structural steel bars 42 are fixedly sleeved at positions near both sides of the wall panel 41 by means of sleeves. The longitudinal structural steel bars 42 penetrate the top of the wall panel 41, and the longitudinal structural steel bars 42 are distributed in an array. Transverse structural steel bars 43 are fixedly sleeved at positions near the front and back of the wall panel 41 on both sides by means of sleeves. The transverse structural steel bars 43 penetrate both sides of the wall panel 41. Fixing holes 44 are provided at positions near both sides of the bottom of the wall panel 41 by means of integral forming. The fixing holes 44 are distributed in a rectangular array. The axes of the fixing holes 44 correspond one to one with the axes of the longitudinal structural steel bars 42. A connecting hole 45 is provided at the top of the fixing hole 44 by means of integral forming. The connecting hole 45 and the fixing hole 44 are in a connected state. Slurry discharge holes 46 are opened at positions near the bottom of both sides of the wall panel 41 by means of integral forming. A grouting hole 47 is opened at a position near the bottom of the front of the wall panel 41 by means of integral forming. The grouting hole 47 is close to both sides of the wall panel 41. The connecting hole 45 is connected to the fixing hole 44, and when concrete is injected into the fixing hole 44 for fixing, the concrete is injected into the fixing hole 44 through the grouting hole 47. Since the connecting hole 45 is connected to each fixing hole 44, the concrete can fill each fixing hole 44 through the connecting hole 45. In the traditional equipment, it is necessary to open through holes near the bottom and the top of the fixing hole 44, and inject through the through holes. In order to ensure that the concrete can fill the fixing hole 44, the pressure must be increased during the injection process. Although the operator will use a wooden plug to block the upper through hole during the injection process, a large amount of concrete will still flow out from the gap between the upper through hole and the wooden plug, resulting in waste. In addition, due to the presence of multiple groups of fixing holes 44, the injection operation needs to be repeated many times, resulting in a long time for the entire injection operation and complicated operation. The present application document avoids these problems and improves the reliability of the device. The device involved in the present application mainly needs to open a single injection hole, thereby reducing the difficulty of making the device. At the same time, the number of openings on the front of the wall panel 41 is reduced, the structural strength of the connection between the bottom of the wall panel 41 and the positioning steel bar 3 is improved, and the problem of damage to the fixing hole 44 due to the decrease in structural strength of the multiple holes during the fixing process is avoided, thereby improving the structural strength of the device. When the device is fixed by injecting concrete through the grouting hole 47, the excess concrete will overflow through the grouting hole 46 and enter the cavity with the top opening formed by the wall panels 41 on both sides after the connection device 5 is installed, and the height of the concrete inside the cavity continues to increase until the interior of the cavity is filled, and the pressure generated inside the fixing hole 44 continues to increase, achieving the effect of compacting the concrete inside the fixing hole 44, thereby improving the firmness of the fixing hole 44 and the positioning steel bar 3, and improving the firmness of the connection of the device. In addition, after the concrete in the cavity with the top opening formed by the wall panels 41 on both sides after the connection device 5 is installed is solidified,A concrete column connecting the wall devices 4 on both sides will be formed, which can initially fill the gap between the wall devices 4 and further reinforce the structure of the wall devices 4, thereby reducing the risk of the wall devices 4 toppling over and improving the safety performance of the device.

[0033] See also Figure 1-Figure 7 The fixing holes 44 and the positioning steel bars 3 are in a one-to-one correspondence.

[0034] See also Figure 1-Figure 9 The connecting device 5 includes a connecting plate 51. Correction grooves 52 are formed on the front of the connecting plate 51 near both sides by milling. The correction grooves 52 are distributed in a linear array from top to bottom. Thinning grooves 53 are formed on the front of the connecting plate 51 at both sides of the center line. The thinning grooves 53 extend from the top of the connecting plate 51 to the bottom of the connecting plate 51. The thinning grooves 53 are connected to the correction grooves 52, so that the thinning grooves 53 divide the connecting plate 51 into three parts. The structure at the thinning grooves 53 is relatively fragile. After the concrete is completely solidified, the connecting plate 51 can be positioned at the thinning grooves 53. The part between the thin grooves 53 is removed, and a space is generated in the middle after the removal. The remaining parts on both sides are pulled out and removed, thereby realizing the rapid removal of the connecting device 5. After the connecting device 5 is removed, since the previous transverse structural reinforcement 43 corresponds to the correction groove 52 one by one, and the connecting device 5 tends to move outward under the pressure of the concrete, further squeezing pressure is generated on the transverse structural reinforcement 43, and the position of the transverse structural reinforcement 43 is corrected to ensure that the position of the transverse structural reinforcement 43 is correct, which provides convenience for the subsequent production of the reinforcement cage and further improves the practicality of the device.

[0035] See also Figure 1-Figure 9 The correction groove 52 corresponds to the transverse structural steel bar 43 one by one, so that during the installation of the connecting plate 51, the position of the transverse structural steel bar 43 can be adjusted through the correction groove 52, so that the transverse structural steel bar 43 can be kept inside the correction groove 52, thereby achieving the fixing effect on the connecting plate 51. In the subsequent installation operation, the wall device 4 and the connecting device 5 can be continuously installed again by the same principle, so that after the first wall device 4 is installed and fixed, the subsequent wall device 4 can be preliminarily fixed by the connecting effect of the connecting device 5. This installation method allows the tower crane to disconnect the lifting connection with the wall device 4 after the lifting is completed and the wall device 4 is connected to the connecting device 5. At this time, the operator can fix the wall device 4 by installing the fixing rod 7, and in this process, the tower crane can lift the subsequent wall device 4, thereby achieving the effect of accelerating the construction progress and improving the practicality of the device.

[0036] See also Figure 1-Figure 2, the material of the connecting device 5 is wooden material.

[0037] See also Figure 1-Figure 7 After the connection device 5 is installed, it forms a cavity with an open top together with the wall panels 41 on both sides, and the slurry discharge hole 46 is connected to the cavity.

[0038] The method of use of the present invention is as follows:

[0039] During use, when concrete is injected into the interior for fixing, concrete is injected into the fixing hole 44 through the grouting hole 47. Since the connecting hole 45 is connected to each fixing hole 44, the concrete can fill each fixing hole 44 through the connecting hole 45. A single injection hole is opened, which reduces the difficulty of making the device and reduces the number of openings on the front of the wall panel 41. The structural strength of the connection between the bottom of the wall panel 41 and the positioning steel bar 3 is improved. The position of the transverse structural steel bar 43 is adjusted through the correction groove 52, so that the transverse structural steel bar 43 can be kept inside the correction groove 52, thereby achieving the fixing effect on the connecting plate 51. In the subsequent installation operation, the wall device 4 and the connecting device 5 can be continuously installed again by the same principle, so that after the first wall device 4 is installed and fixed, the subsequent wall devices 4 can be preliminarily fixed by the connecting effect of the connecting device 5. This installation method allows the tower crane to be installed after the hoisting and fixing are completed. After the wall device 4 is connected to the connecting device 5, the lifting connection with the wall device 4 can be disconnected. At this time, the operator can fix the wall device 4 by installing the fixing rod 7. In the process, the tower crane can lift the subsequent wall device 4. After the connecting device 5 is installed, it forms a cavity with a top opening with the wall panels 41 on both sides. The grouting hole 46 is connected to the cavity. When the device is fixed by injecting concrete through the grouting hole 47, the excess concrete will overflow through the grouting hole 46 and enter the cavity with a top opening formed with the wall panels 41 on both sides after the connecting device 5 is installed. The height of the concrete increases continuously until the interior of the cavity is filled up, and the pressure generated inside the fixing hole 44 increases continuously, so as to achieve the effect of compacting the concrete inside the fixing hole 44, thereby improving the firmness of the fixing hole 44 and the positioning steel bar 3. After the connection device 5 is installed, the concrete in the cavity with the top opening formed by the wall panels 41 on both sides solidifies, and a concrete column connecting the wall devices 4 on both sides will be formed. The concrete column can preliminarily fill the gap between the wall devices 4 and further reinforce the structure of the wall devices 4. The thinning groove 53 divides the connecting plate 51 into three parts, and the structure at the thinning groove 53 is relatively fragile. After the concrete has completely solidified, the portion of the connecting plate 51 between the thinning grooves 53 can be removed through the thinning grooves 53. After the removal, a space is created in the middle, and the remaining portions on both sides are pulled out and removed, thereby achieving rapid removal of the connecting device 5. After the connecting device 5 is removed, since the previous transverse structural reinforcement 43 corresponds to the correction groove 52 one by one, and the connecting device 5 tends to move outward under the pressure of the concrete, further squeezing pressure is generated on the transverse structural reinforcement 43, and the position of the transverse structural reinforcement 43 is corrected to ensure that the position of the transverse structural reinforcement 43 is correct, providing convenience for the subsequent production of the steel cage.
