Currently, in the construction industry, more and more buildings (such as high-rise or super high-rise buildings) are beginning to adopt an aluminum alloy formwork system for concrete slurry building construction. The specific process is briefly described as follows: the method comprises the steps of building a framework on the current floor by using a steel reinforcement cage, paving an aluminum alloy template, pouring concrete slurry, and forming structures such as a floor slab, a beam, a column and the like after the concrete slurry is solidified, so that the construction of one floor of the building is completed. In the process, a preset embedded part is adopted to reserve a material conveying port, the aluminum alloy template paved on the current floor is disassembled and then is conveyed to the position of the previous floor from bottom to top through the material conveying port, then the steps of paving, concrete slurry pouring and the like are carried out, and the steps are repeated until the whole building is built and molded.

It can be understood that after each floor is built, the material conveying port needs to be plugged so as to ensure the integral forming quality of the building and eliminate potential safety hazards.

As shown in fig. 1 and 4, an embedded device shown in an embodiment of the present application includes: a shell seat, a baffle plate 20 and a lifting driving mechanism 30. The shell base is a main body structure of the embedded device and is used for bearing the fixed baffle 20 and the lifting driving mechanism 30. In addition, the lower end of the shell seat is detachably provided with a preset aluminum template 10, and the preset aluminum template 10 is used for fixing the shell seat in a fixed position when concrete slurry is poured. Because the surface area of the preset aluminum template 10 is larger than that of the shell seat, the pressure area is large when concrete slurry is poured, the shell seat can keep the preset position stable under the heavy pressure of the concrete slurry, and the forming quality of the material conveying port and the floor plate can be ensured. When the floor board solidifies the shaping, and pass the material mouth shaping after, can directly with the shell seat dismantle can, preset aluminium template 10 and can bury underground inside the concrete, can not lead to the fact the influence to the normal use of material mouth and the structural strength of building.

Optionally, in this embodiment, the housing base and the preset aluminum mold plate 10 are both rectangular. Or in other embodiments, the housing seat and the pre-positioned aluminum mold plate 10 may have other shapes such as a circle, a triangle, etc.

In addition, it is ensured that the height of the top surface of the housing base is set to be lower than the thickness of the concrete paste, in terms of the size of the housing base. So as to avoid the subsequent obstruction to the trowelling tool during the trowelling operation of the concrete slurry. And after the concrete slurry is primarily solidified, the structural strength of the concrete slurry is high, so that the concrete slurry cannot fall into the shell seat in a leveling operation even if the height of the shell seat is lower than the top surface height of the concrete slurry.

The baffle 20 is arranged on the shell base in a lifting and moving manner. The baffle 20 is a rectangular annular plate body with the same shape as the shell seat, and the size of the baffle is slightly smaller than the size of the inner cavity of the shell seat so as to eliminate the friction resistance with the inner wall of the shell seat and ensure smooth lifting movement. The lifting driving mechanism 30 is disposed on the housing base and is used for driving the baffle plate 20 to ascend or descend, and when the baffle plate 20 ascends, the height of the top surface of the baffle plate 20 is set to be higher than the thickness of the concrete slurry.

In summary, the implementation of the technical solution of the present embodiment has the following beneficial effects: the pre-buried device is applied to a building floor construction link, and particularly relates to a pre-arranged material outlet and material conveying port on a floor slab between two adjacent layers up and down, so that an aluminum template can be quickly transported inside a building, vertical transportation equipment is prevented from being occupied, and construction efficiency is improved. Specifically, during construction, the shell base can be firstly assembled and connected with the preset aluminum template 10, then the whole shell base is arranged at a position where a material conveying port needs to be reserved, the lifting driving mechanism 30 is in a contraction state at the moment, and the baffle 20 is hidden in the shell base and is not higher than the top surface of the shell base; and then, concrete slurry is poured, the preset aluminum template 10 can be completely covered by the concrete slurry, the pre-embedded device cannot loosen under the action of heavy pressure of the concrete slurry, after the concrete slurry is poured, the lifting driving mechanism 30 is operated to lift the baffle plate 20 and place the baffle plate in a position (generally 1 cm-2 cm higher) higher than the top surface of the shell seat, and under the action of the baffle plate 20, the concrete slurry is preliminarily solidified, so that the forming precision and quality of the material conveying port and the concrete can be ensured. Finally, before the floating construction operation, the lifting driving mechanism 30 is operated again to lower the baffle 20 to the interior of the shell seat, and the top surface of the shell seat is set to be lower than the thickness of the concrete slurry, so that a blocking object higher than the surface of the concrete does not exist at the moment, the floating operation can be effectively and reliably carried out, and the construction efficiency and the floating quality are ensured.

It can be understood that, rise baffle 20 behind the concreting slurry, aim at plays the side direction fender to the concrete slurry and protects the effect, also plays to enclose the fender effect to the material mouth promptly, guarantees that the concrete solidifies the design. After the concrete is preliminarily solidified, the baffle 20 is lowered, and the top surface height of the shell base is lower than that of a concrete layer (formed by solidification of poured concrete rubber materials), so that the purpose of avoiding obstacles to cause unsmooth troweling operation and influencing the flatness of the surface of the trowelled concrete layer is achieved.

With continued reference to fig. 2-5, in order to achieve the lifting movement of the baffle 20, in some embodiments, the housing base includes a housing 40, and the housing 40 is used for detachably connecting with the pre-positioned aluminum mold plate 10. The lifting driving mechanism 30 includes a driving seat 31 disposed on the inner wall of the housing 40, and a driving rod 32 slidably disposed on the driving seat 31, wherein the driving rod 32 is connected to the baffle 20. The constructor stands at the lower layer of the building and can drive the baffle 20 to move downwards by pulling the driving rod 32 downwards; and pushing the driving rod 32 upward can drive the baffle 20 to ascend. The baffle 20 is simple in lifting operation mode and easy to implement.

On the basis of the above embodiments, there are various structural manners for connecting the driving rod 32 and the driving seat 31. For example, in some embodiments, the driving seat 31 is provided with a sliding hole, and the driving rod 32 is slidably inserted into the sliding hole. The driving rod 32 is inserted into the sliding hole, so that the connection strength between the driving rod 32 and the driving seat 31 can be improved, the structural integrity of the lifting driving mechanism 30 is enhanced, and when the driving rod 32 is pulled or pushed, the hole wall of the sliding hole can play a role in guiding and limiting the driving rod 32, thereby further ensuring that the baffle 20 is reliably and stably lifted and moved. And because constructor is located the below operation of pre-buried device, even if the driving lever 32 is not held firmly to the losing hand, the driving lever 32 can not take place to drop under the restriction of drive seat 31 yet, can avoid causing the injury to the constructor of below. Preferably, the slide hole is a circular hole, and the driving rod 32 is a circular rod, so that the assembly difficulty can be reduced to a certain degree.

It should be noted that, in order to reduce the force applied by the operator and the labor intensity, the diameter of the slide hole is slightly larger than the diameter of the driving rod 32 to reduce the adverse effect of the frictional resistance.

In addition, in order to stop the raised baffle 20 at the current position even when the jacking force of the constructor is lost, in some embodiments, the diameter of the slide hole is matched with that of the driving rod 32, and the aim of mutual limiting is achieved by means of fastening and matching force of the hole wall of the slide hole and the outer wall of the driving rod 32. Or in other embodiments, the inner wall of the sliding hole is provided with a first thread, the outer wall of the driving rod 32 is provided with a second thread, and the first thread is screwed with the second thread. Adopt threaded connection structure, not only change in the operation actuating lever 32 and rise or descend to guarantee that the lift height of baffle 20 is accurate controllable, simultaneously because the helicitic texture itself possesses the auto-lock ability, can guarantee that baffle 20 rises or descends the back and stabilize and stop at the current position, promote pre-buried device's use reliability and security.

Of course, in some other embodiments, other mechanisms or devices capable of achieving the lifting driving in the prior art may be used instead of the thread lifting mechanism, for example, but not limited to, a screw rod slider mechanism, a scissor fork mechanism, an electric push rod, a cylinder, a linear motor, and the like, and are also within the protection scope of the present application, and are not described herein again.

With continued reference to fig. 2 and 4, in some embodiments, the lifting driving mechanism 30 further includes a supporting frame 33, the supporting frame 33 is mounted on an inner sidewall of the baffle plate 20, and the supporting frame 33 is connected to the driving rod 32. By installing the supporting frame 33, the structural strength of the baffle 20 can be enhanced, and the sinking deformation caused by the lateral extrusion force of the concrete can be avoided; meanwhile, the support frame 33 also serves to achieve interconnection of the driving rod 32 and the barrier 20 to transmit a lifting driving force. In this embodiment, the supporting frame 33 is a structural member welded or assembled by metal profiles, and specifically includes a longitudinal profile and two transverse profiles, and the two transverse profiles are vertically connected to the longitudinal profile near the middle portion. Preferably, considering the large size of the embedded device, two driving rods 32 and the driving seat 31 are adopted to simultaneously drive the baffle 20 to move up and down, so as to ensure uniform stress and smooth movement. Wherein the two driving rods 32 are respectively connected to the joints of the two transverse profiles and the longitudinal profile, and the joints have high strength and are more reliably stressed.

After the concrete floating construction is finished, the embedded device needs to be disassembled integrally (except for the preset aluminum formwork 10), at this time, in order to conveniently disassemble the driving rod 32 and the driving seat 31, in some embodiments, the lifting driving mechanism 30 further comprises a connecting block 34, the connecting block 34 is installed on the supporting frame 33, the connecting block 34 is provided with a clamping groove 341, the driving rod 32 is provided with a clamping body 321, and the clamping body 321 can be detachably clamped in the clamping groove 341. At this time, the clamping body 321 is pulled out from the clamping groove 341 with a little force, so that the driving rod 32 and the supporting frame 33 can be separated, the operation is convenient and labor-saving, and the practicability is good. Specifically, the clamping groove 341 is a notch recessed inwards along the bottom surface of the connecting block 34, two opposite side walls of the notch respectively protrude towards the middle of the notch to form clamping blocks, and the two clamping blocks are opposite to each other; accordingly, two oppositely disposed grooves are formed between the card body 321 and the main body of the driving rod 32. During the installation, can directly push the card body 321 from the side direction opening of breach, two fixture block alright one-to-one's inlay card is to two recesses in, so axial displacement degree of freedom and the rotational degree of freedom of restriction actuating lever 32 and connecting block 34 that alright be fine, when actuating lever 32 drive braced frame 33 and baffle 20 removed, can ensure to be connected firmly with connecting block 34, guarantee that drive power transmission is reliable.

Referring to fig. 3 to 5, in addition, since the baffle 20 is large in size and made of a metal material, the weight of the baffle 20 is correspondingly large. If the baffle 20 is simply installed on the inner side of the housing 40, the housing 40 can only laterally support the baffle 20 on one side, which is not favorable for the baffle 20 to stably move up and down. In view of this, in some embodiments, the housing base further includes an inner housing 50, the inner housing 50 is mounted inside the outer housing 40 and is in clearance fit with the inner wall of the outer housing 40, and the baffle 20 is disposed in the clearance between the inner housing 50 and the outer housing 40 in a lifting movement. Thus, the baffle 20 is arranged between the outer shell 40 and the inner shell 50, so that the baffle 20 can be bilaterally limited and guided when being lifted and moved, and the movement is more stable. The clearance fit is used to reduce frictional resistance and reduce wear between the outer shell 40 and the inner shell 50 and the baffle 20.

Alternatively, the inner shell 50 and the outer shell 40 are locked together using a bolt assembly. Or the assembly connection can be realized by adopting other modes such as a buckle, a magnetic attraction and the like. The connection mode is simple, and the reliability is high.

Since the inner shell 50 is disposed between the baffle 20 and the supporting frame 33, in order to avoid the inner shell 50 from causing blocking interference to the supporting frame 33, in some embodiments, the inner shell 50 is provided with an avoiding through hole 51, and the supporting frame 33 is slidably inserted into the avoiding through hole 51. Specifically, the number of the avoidance through holes 51 is six, and the avoidance through holes are respectively matched with two end portions of the longitudinal section bar and four end portions of the two transverse section bars in a one-to-one correspondence manner. It should be noted that the avoiding through hole 51 is vertically extended, and the length thereof should be greater than the maximum rising height of the baffle 20, so as to avoid blocking interference on the supporting frame 33 and influence on normal rising and falling of the baffle 20.

According to the scheme, after the material conveying port is formed, all the components except the embedded device of the preset aluminum template 10 need to be lifted upwards for dismounting, namely the preset aluminum template 10 needs to be detached from the shell seat. To achieve this, in some embodiments, the pre-positioned aluminum template 10 is provided with a slot, and the shell seat is inserted into the slot; or the shell seat is provided with a jack, the preset aluminum template 10 is provided with an inserting plate, and the inserting plate is inserted into the jack. So, conveniently preset aluminium template 10 and shell seat and split each other, the simple operation and laborsaving.

Or, as an alternative to the above embodiment, in another embodiment, the preset aluminum mold plate 10 is provided with a first mounting hole, the shell base is provided with a second mounting hole, and the fastening member is detachably inserted into the first mounting hole and the second mounting hole for fixing. The fastener is a bolt assembly consisting of a bolt and a nut, the first mounting hole and the second mounting hole are through holes, the bolt sequentially penetrates through the two through holes and then is locked with the nut, and the preset aluminum template 10 and the shell seat can be quickly connected and fixed.

In order to facilitate the whole shell base to be separated from the constraint of the peripheral concrete layer, the outer wall of the shell 40 is also designed with a guide surface. Alternatively, the lead-out surface may be a slope, a circular arc, or the like. For example, when the leading-out surface is an inclined surface, the inclined surface is inclined inward in the center direction of the embedded device from the top surface to the bottom surface of the housing 40.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
