Description

Technical Field

[0001] The invention relates to the field of prefabricated hollow wallboard construction, in particular to a prefabricated hollow wallboard joint sealing structure. Background Art

[0002] Prefabricated wall panels refer to reinforced concrete slab components that are processed in the prefabrication yard and transported to the construction site for assembly. They have the advantages of being less affected by seasons, low cost, and short construction period. For ease of transportation, prefabricated wall panels are usually produced as hollow wall panels in the prefabrication yard, and then the hollow wall panels are transported to the construction site for secondary pouring, and the cavity inside the wall panels is filled densely with concrete.

[0003] Reference Figure 1 The related art discloses a prefabricated hollow wall panel 1, the bottom of which is provided with a 5 cm support leg 12. After the prefabricated hollow wall panel 1 is assembled on site, there is a gap between the wall panel 1 and the floor slab to form a lower joint 11. When the hollow wall panel 1 is poured for the second time, the poured concrete will leak from the lower joint 11 of the hollow wall panel 1, which is particularly troublesome for the construction workers to handle later. Therefore, it is necessary to seal the gap between the hollow wall panel 1 and the floor slab.

[0004] The Chinese patent with announcement number CN212104594U discloses a joint sealing device for the lower opening of a prefabricated structure composite floor, which includes a prefabricated wall panel spliced ​​with the composite floor, a joint is formed between the prefabricated wall panel and the composite floor, square steels are sealed at positions corresponding to the joints on both sides of the prefabricated wall panel, and a plurality of reinforcing plates are distributed at intervals on the outside of the square steels, the reinforcing plates on the two square steels correspond to each other, and the corresponding two reinforcing plates are connected to each other by a plurality of tension bolts. In this joint sealing method, construction workers need to tighten a plurality of tension bolts in sequence, which is a relatively troublesome operation. Utility Model Content

[0005] In order to make it more convenient for construction workers to operate when sealing the lower joints of prefabricated hollow wall panels and to facilitate the secondary pouring of the prefabricated hollow wall panels, the present application provides a prefabricated hollow wall panel joint sealing structure.

[0006] The present application provides a prefabricated hollow wall panel joint sealing structure adopts the following technical solution:

[0007] A prefabricated hollow wall panel joint sealing structure includes a sealing plate, a pull plate and a locking pin, wherein at least one sealing plate is respectively arranged at the lower seam on both sides of the wall panel, and at least one pull hole for the pull plate to pass through is opened on the sealing plate, and the pull holes on the sealing plates on both sides of the wall panel are arranged correspondingly, and the pull plate passes through the sealing plates on both sides of the wall panel in sequence; at least one locking pin is respectively arranged at both ends of the pull plate, and a pin hole is arranged on the pull plate. When the locking pin is inserted in the pin hole, the locking pin is tightly abutted against the sealing plate, and the sealing plate is tightly fitted to the wall panel.

[0008] By adopting the above technical scheme, before the secondary pouring of the hollow wall panel, the sealing plates are placed at the lower joints on both sides of the wall panel respectively, and then the pull plates are passed through the sealing plates on both sides of the wall panel at the same time, and the locking pins are inserted into the pin holes. The locking pins abut against the sealing plates so that the bottom plate and the wall surface of the wall panel fit tightly, thereby achieving the sealing of the lower joint of the wall panel, and the construction workers do not need to tighten the bolts multiple times, and the operation is more convenient.

[0009] Optionally, the side of the locking pin away from the sealing plate is a guide surface, and the side close to the sealing plate is an abutment surface. The guide surface is inclined to the wall surface, and the guide surface is tightly fitted to the side wall of the pin hole. When the locking pin is inserted into the pin hole, the abutment surface moves in the direction close to the wall sealing plate.

[0010] By adopting the above technical solution, the guide surface is always in contact with the side wall of the pin hole. When the locking pin is inserted into the pin hole, the abutment surface can force the blocking plate to move toward the wall panel, so that the blocking plate is tightly fitted to the wall panel.

[0011] Optionally, a plurality of pull plates are arranged on the same blocking plate, a plurality of locking pins are arranged corresponding to the pull plates, and a control component is provided on the blocking plate for controlling the simultaneous sliding of the plurality of locking pins to drive the blocking plate to move in a direction against the wall panel.

[0012] By adopting the above technical solution, multiple locking pins on multiple pull plates simultaneously exert force on the blocking plate to make the blocking plate fit with the wallboard, and the blocking plate is subjected to more uniform force, thereby providing a tighter seal for the lower seam of the wallboard. At the same time, the control component can simultaneously control multiple locking pins to closely abut against the blocking plate, making the operation more convenient.

[0013] Optionally, the control assembly includes an eccentric wheel rotatably disposed on the blocking plate, and the eccentric wheel abuts against the locking pin.

[0014] By adopting the above technical solution, when the eccentric wheel abuts against the locking pin, the eccentric wheel rotates, and the distance between the side wall of the eccentric wheel close to the locking pin and the locking pin changes. The eccentric wheel applies a force to the locking pin to make the locking pin move in the direction of abutting the sealing plate, so that the sealing plate seals the lower joint of the wall panel.

[0015] Optionally, the eccentric wheels correspond to the locking pins one by one, and at least two eccentric wheels located on the same side of the wall panel are coaxially arranged and penetrated by a control shaft, and the control shaft is rotatably supported on the blocking plate.

[0016] By adopting the above technical solution, the rotating control shaft can control multiple eccentric wheels to rotate simultaneously, so that multiple locking pins are pressed against the blocking plate at the same time.

[0017] Optionally, a connecting sleeve is fixedly provided on the eccentric wheel, and the connecting sleeve is slidably mounted on the control shaft. A bracket is slidably provided on the blocking plate, and the connecting sleeve is rotatably mounted on the bracket.

[0018] By adopting the above technical solution, the eccentric wheel can slide with the bracket relative to the sealing plate and the control shaft. When the locking pin needs to be inserted into the pin hole or pulled out from the pin hole, the eccentric wheel can be slid to disengage the eccentric wheel from the locking pin, making it more convenient to remove the locking pin.

[0019] Optionally, an elastic member is provided between the bracket and the blocking plate, and the elastic member applies a force to the bracket so that the bracket has a tendency to drive the eccentric wheel to slide in a direction close to the locking pin.

[0020] By adopting the above technical solution, when there is no external force, the eccentric wheel is always located in a position coordinated with the locking pin under the action of the elastic member. When the construction personnel control the locking pin to press against the sealing plate, there is no need to slide the locking pin to align the locking pin and the eccentric wheel, which makes the operation more convenient.

[0021] Optionally, the eccentric wheel is provided with anti-slip grooves.

[0022] By adopting the above technical solution and providing anti-skid grooves, the friction between the eccentric wheel and the locking pin when they abut against each other is increased, thereby reducing the possibility of slipping between the eccentric wheel and the locking pin.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 2-5 This application is described in further detail.

[0030] The present application embodiment discloses a prefabricated hollow wall panel joint sealing structure. Figure 2 and Figure 3 The prefabricated hollow wall panel joint sealing structure includes a sealing plate 2, a pull plate 3 and a locking pin 4. The sealing plates 2 are arranged in pairs, and the two sealing plates 2 arranged in pairs are respectively located at the lower joints 11 on both sides of the wall panel 1. According to the length of the wall panel 1, multiple pairs of sealing plates 2 can be set, and the multiple pairs of sealing plates 2 are arranged along the length direction of the wall panel 1 and are tightly fitted end to end, so that the lower joint 11 of the wall panel 1 can be sealed; the sealing plates 2 in this embodiment take two pairs as an example, and each sealing plate 2 corresponds to multiple pull plates 3, and the locking pin 4 is respectively arranged at both ends of the pull plate 3, and a pin hole 31 is opened on the pull plate 3. Inserting the locking pin 4 in the pin hole 31 can make the locking pin 4 abut against the sealing plate 2, so that the sealing plate 2 and the wall panel 1 are tightly fitted to achieve the sealing of the lower joint 11 of the wall panel 1, and the operation is relatively convenient.

[0031] Reference Figure 2 and Figure 3 The pull plate 3 is in the shape of a long rectangular plate. The pull plate 3 passes through the lower seam 11 below the wall panel 1, and both ends are inserted into the two blocking plates 2 arranged in pairs. The blocking plates 2 are correspondingly provided with pull holes 21 for the pull plate 3 to pass through; a pin hole 31 is respectively provided at both ends of the pull plate 3, a part of the pin hole 31 is located below the blocking plate 2, and the other part is located on the side of the blocking plate 2 away from the wall panel 1, and the locking pin 4 is inserted into the pin hole 31, and the side of the locking pin 4 close to the blocking plate 2 abuts against the blocking plate 2; the locking pin 4 and The surface that the blocking plate 2 abuts is the abutment surface 41, and the surface of the locking pin 4 away from the blocking plate 2 is the guide surface 42. The guide surface 42 is inclined to the wall surface. In this embodiment, the guide surface 42 gradually approaches the blocking plate 2 from top to bottom. In the process of inserting the locking pin 4 downward into the pin hole 31, the guide surface 42 is always abutted against the side wall of the pin hole 31 away from the wall panel 1, and the abutment surface 41 gradually moves toward the direction close to the blocking plate 2, and finally tightly abuts against the blocking plate 2, so that the blocking plate 2 is tightly fitted with the wall panel 1 to achieve blocking.

[0032] Reference Figure 3 and Figure 4 In order to simultaneously control multiple locking pins 4 to slide downward and tightly abut against the blocking plate 2, a control component 5 is provided on the blocking plate 2, the control component 5 corresponds to the blocking plate 2 one by one, and is arranged above the locking pin 4; the control component 5 includes a control shaft 51 and a plurality of eccentric wheels 52, the control shaft 51 extends along the length direction of the blocking plate 2, and both ends are rotatably supported on the side of the blocking plate 2 away from the wall panel 1 through support plates; the eccentric wheels 52 correspond to the locking pins 4 one by one, the eccentric wheels 52 are flat cylindrical, the eccentric wheels 52 abut against the upper side wall of the locking pin 4, and the rotation of the eccentric wheels 52 can drive the locking pin 4 to move downward; the outer side wall of the eccentric wheel 52 is provided with a plurality of anti-skid grooves 22, the anti-skid grooves 22 are opened along the axial direction of the eccentric wheel 52, and the plurality of anti-skid grooves 22 form anti-skid patterns 521 to increase the friction between the eccentric wheel 52 and the locking pin 4.

[0033] Reference Figure 3 and Figure 4 A connecting sleeve 53 is fixedly mounted on the eccentric wheel 52. The axis of the connecting sleeve 53 is offset from the axis of the eccentric wheel 52. The connecting sleeve 53 is coaxially mounted on the control shaft 51. The rotation of the control shaft 51 can drive the eccentric wheel 52 to rotate, thereby driving the locking pin 4 to slide downward, so that the blocking plate 2 fits the wallboard 1. In order to facilitate the construction personnel to rotate the control shaft 51 to control the simultaneous rotation of multiple eccentric wheels 52, a knob 6 is fixedly mounted on the control shaft 51. The construction personnel can control the downward movement of multiple locking pins 4 by rotating the knob 6, so that the blocking plate 2 fits the wallboard 1.

[0034] Reference Figure 5 Specifically, a limiting block 531 is integrally provided on the inner wall of the connecting sleeve 53, and a limiting groove 511 is provided on the control shaft 51 along its length direction. The limiting block 531 is slidably embedded in the limiting groove 511, so that the connecting sleeve 53 and the control shaft 51 rotate synchronously, and at the same time, the eccentric wheel 52 can slide relative to the control shaft 51; when it is necessary to pull the locking pin 4 out of the pin hole 31, the eccentric wheel 52 is slid to one side, so that the eccentric wheel 52 can be separated from the locking pin 4.

[0035] Reference Figure 4 and Figure 5In order to facilitate the sliding installation of the eccentric wheel 52, a bracket 7 is slidably arranged on the blocking plate 2, and the bracket 7 is in a "U" shape. The eccentric wheel 52 is located inside the "U" shape of the bracket 7, and the two ends of the connecting sleeve 53 are rotatably penetrated on the two parallel side walls of the bracket 7, so that the eccentric wheel 52 is rotatably installed on the bracket 7; the bracket 7 is slidably installed on the blocking plate 2 through a slider 71, and a slide groove 22 for the slider 71 to slide is provided on the blocking plate 2, one end wall of the slide groove 22 is arranged close to the locking pin 4, and the other end wall is arranged away from the locking pin 4. When the slider 71 and the slide groove 22 are in contact with the end wall of the locking pin 4, the eccentric wheel 52 is located directly above the pin hole 31 and can abut against the locking pin 4.

[0036] Reference Figure 4 and Figure 5 , an elastic member 72 is provided in the slide groove 22. In the present embodiment, the elastic member 72 is a spring. One end of the spring is fixedly connected to the end wall of the slide groove 22 away from the locking pin 4, and the other end is fixedly connected to the slider 71. The spring is in a compressed state. The spring exerts a force on the bracket 7 in the direction of the horizontal locking pin 4, so that the eccentric wheel 52 always tends to slide just above the locking pin 4; when the locking pin 4 needs to be removed, the bracket 7 is pushed in the direction close to the elastic member 72, and the eccentric wheel 52 moves accordingly, so that the eccentric wheel 52 can be separated from the locking pin 4.

[0037] The implementation principle of a prefabricated hollow wall panel joint sealing structure in an embodiment of the present application is as follows: before the secondary pouring of the hollow wall panel 1, two pairs of sealing plates 2 are respectively placed at the joint positions below the two sides of the wall panel 1, and the two adjacent sealing plates 2 located on the same side of the wall panel 1 are tightly fitted, and then a plurality of pull tabs are sequentially passed through the pull holes 21 on the sealing plates 2 and the lower joint 11 of the wall panel 1. At this time, the eccentric wheel 52 is located above the pin hole 31 on the pull tab, and the eccentric wheel 52 is manually slid to the side close to the elastic member 72, and the locking pin 4 is inserted into the pin hole 31, and the abutting surface 41 of the locking pin 4 is fitted with the sealing plate 2, and then the eccentric wheel 52 is stopped. When external force is applied, the eccentric wheel 52 is reset under the action of the elastic member 72 and is located directly above the locking pin 4. Multiple locking pins 4 are inserted into the pin holes 31 in sequence. Construction personnel can simultaneously rotate the control shafts 51 on both sides of the wall panel 1 through the pin holes 31 on the control shaft 51. Multiple eccentric wheels 52 on the same blocking plate 2 rotate accordingly and drive the locking pins 4 to move downward. The abutment surface 41 of the locking pin 4 forces the blocking plate 2 to move toward the direction close to the wall panel 1, so that the blocking plates 2 on both sides of the wall panel 1 fit tightly with the wall panel 1, thereby sealing the joint between the wall panel 1 and the floor slab. After the secondary pouring is completed, the blocking plate 2 and the pull plate 3 need to be removed. In this embodiment, when sealing the lower joint 11 of the wall panel 1, the pin is inserted into the pin hole 31, and then the control shaft 51 is rotated, which is relatively convenient to operate.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
