Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.

[ first embodiment ] A

Referring to fig. 1, it is a schematic structural diagram of a prefabricated capping beam sideform pre-positioning apparatus 100 according to a first embodiment of the present invention. The prefabricated capping beam-side formwork pre-positioning device 100 includes, for example: the formwork comprises a fixed base plate 10, at least one prefabricated formwork 20, a plurality of first cushion blocks 40 and a plurality of side formwork positioning devices 30 arranged between the prefabricated formwork 20 and the first cushion blocks 40.

Specifically, referring to fig. 2, the fixing base plate 10 is provided with a first mounting surface 11 and a plurality of mounting positions 12 circumferentially arranged on the first mounting surface 11, and the prefabricated formwork 20 is mounted on the first mounting surface 11 through the plurality of mounting positions 12.

Preferably, the first mounting surface 11 is higher than the plurality of mounting positions 12 to form a protruding mounting surface; the prefabricated formwork 20 can be tightly attached to the extended mounting surface through the extended mounting surface, so that the first mounting surface 11 not only can play a mounting role, but also can play a positioning role.

Specifically, referring to fig. 3, the prefabricated form 20 includes, for example: prefabricated die block board 21, two prefabricated side form boards 22 and prefabricated top form board 23, and prefabricated die block board 21 locates the bottom of prefabricated template 20, and two prefabricated side form boards 22 locate prefabricated die block board 21's both sides respectively, and two prefabricated side form boards 22 are located to prefabricated top form board 23 lid, form through again with PMKD 10 cooperation and prefabricate and pour and hold chamber 24.

Further, the prefabricated cover beam side formwork pre-positioning device 100 further comprises: a plurality of first head blocks 40 and a plurality of second head blocks 50. The plurality of first cushion blocks 40 and the plurality of second cushion blocks 50 are arranged at the bottom of the prefabricated bottom template 21, and the plurality of second cushion blocks 50 are arranged among the plurality of first cushion blocks 40.

For example, after the prefabricated form 20 and the fixed base plate 10 are installed, the prefabricated form 20 and the fixed base plate 10 need to be transformed from the horizontal state to the vertical state, and then pouring is performed. Therefore, when the prefabricated template 20 and the fixed bottom plate 10 are installed, the plurality of first cushion blocks 40 and the plurality of second cushion blocks 50 are arranged at the bottom of the prefabricated template 20, so that on one hand, the prefabricated template 20 and the fixed bottom plate 10 can be hung and aligned more conveniently, and the prefabricated template 20 and the fixed bottom plate 10 are changed from a transverse state to a vertical state; on the other hand, the bottom of the prefabricated bottom mold plate 21 can be prevented from sliding and thus being worn.

Specifically, the first mounting part 221 is arranged on the outer side of the prefabricated side template 22, the second mounting parts 41 are arranged on the plurality of first cushion blocks 40, and the plurality of side template positioning devices 30 are sequentially and telescopically mounted between the first mounting part 221 and the second mounting parts 41.

Preferably, the first mounting parts 221 are provided on both sides of the prefabricated sideform 22, respectively, so that the sideform positioning devices 30 can be provided on both sides of the prefabricated sideform 22, respectively. For example, on the one hand, when the prefabricated sideform 22 is mounted with a deviation, the sideform positioning devices 30 provided on both sides of the prefabricated sideform 22 are adjusted, and if the prefabricated sideform 22 is deviated to the inner side, the length of the sideform positioning device 30 is shortened; if the prefabricated sideform 22 is shifted outwardly, extending the length of the sideform positioning means 30; on the other hand, after the prefabricated sideforms 22 are mounted, the sideform positioning device 30 may fix the prefabricated sideforms 22 to prevent the mounted prefabricated sideforms 22 from shifting, and when the remaining prefabricated sideforms 22 are hoisted, the mounted prefabricated sideforms 22 may tilt and turn sideways if the prefabricated sideforms 22 collide.

Specifically, the sideform positioning apparatus 30 includes, for example: a first adjustment lever 31, a second adjustment lever 32, and a third adjustment lever 33. Wherein, one end of the first adjusting rod 31 is provided with a first fixing hole, and the other opposite end is provided with a first threaded rod; one end of the second adjusting rod 32 is provided with a second fixing hole, and the other opposite end is provided with a second threaded rod; a through threaded hole is formed in the third adjusting rod 33, and the third adjusting rod 33 is sleeved with the first adjusting rod 31 and the second adjusting rod 32.

Further, the first fixing hole and the first mounting part 221 and the second fixing hole and the second mounting part 41 are fixedly connected by a bolt or a bolt.

Preferably, referring to fig. 7, a through hole perpendicular to the threaded hole is formed in the middle of the third adjustment lever 33. For example, the sideform positioning apparatus 30 may have an effect of extending and retracting the sideform positioning apparatus 30 by rotating the third adjustment lever 33, but since the prefabricated sideform 22 has a heavy weight, it requires a large force to directly rotate the third adjustment lever 33, but long and thin objects such as sticks or reinforcing bars are inserted into the through holes, the third adjustment lever 33 may be easily rotated by rotating the long and thin objects such as sticks or reinforcing bars, and the amount of rotation of the third adjustment lever 33 may be better controlled, so that the prefabricated sideform 22 is more accurately mounted on the prefabricated bottom form 21.

Preferably, the pitch on the first threaded rod is not equal to the pitch on the second threaded rod; the threaded hole includes: a first threaded hole and a second threaded hole; wherein the first threaded hole is engaged with the first threaded rod, and the second threaded hole is engaged with the second threaded rod.

For example, if the pitch of the first threaded rod is greater than the pitch of the second threaded rod, when the third adjustment lever 33 is rotated in one direction, the distance of engagement between the third adjustment lever 33 and the first threaded rod becomes larger, the distance of engagement between the third adjustment lever 33 and the second threaded rod becomes smaller, and the distance of the smaller is smaller than the distance of the larger, the length of the sideform positioning apparatus 30 is gradually shortened; when the third adjustment lever 33 is rotated in the other direction, the distance of engagement between the third adjustment lever 33 and the first threaded rod becomes smaller, and the distance of engagement between the third adjustment lever 33 and the second threaded rod becomes larger, and the length of the sideform positioning apparatus 30 gradually increases as the distance becomes smaller than the distance becomes larger.

Preferably, with reference to fig. 8, the direction of rotation of the first threaded rod is opposite to the direction of rotation of the second threaded rod; the threaded hole includes: a first threaded hole and a second threaded hole; wherein the first threaded hole is matched with the first threaded rod, and the second threaded hole is matched with the second threaded rod.

For example, when the third adjusting rod 33 is rotated along one direction, the distance between the third adjusting rod 33 and the first threaded rod is increased, the distance between the third adjusting rod 33 and the second threaded rod is also increased, and the length of the sideform positioning device 30 is gradually shortened; when the third adjustment lever 33 is rotated in the other direction, the distance of engagement between the third adjustment lever 33 and the first threaded rod is reduced, and the distance of engagement between the third adjustment lever 33 and the second threaded rod is also reduced, so that the length of the sideform positioning apparatus 30 is gradually extended.

Specifically, referring to fig. 4, the prefabricated capping beam-side template pre-positioning device 100 further includes, for example: a plurality of connectors. Wherein each connecting piece is arranged at two ends of the prefabricated bottom formwork 21 and/or the two prefabricated side formworks 22 and/or the prefabricated top formwork 23.

For example, the height of the prefabricated bent cap can be varied according to the actual required size, so that a higher prefabricated bent cap has a lower prefabricated bent cap. Therefore, in order to make the prefabricated form 20 suitable for the columns with more heights, the prefabricated form 20 is set to be shorter and different in length, and when a lower prefabricated capping beam needs to be manufactured, the suitable prefabricated form 20 can be directly used; when a higher prefabricated capping beam is to be fabricated, a plurality of prefabricated formworks 20 may be spliced together to reach the height of the prefabricated capping beam. A plurality of prefabricated forms 20 are better secured together by a plurality of said connectors.

Further, the connecting member includes, for example: the first connecting plate 25, the first connecting hole 251 and the second connecting plate 26 provided on the first connecting plate 25, and the second connecting hole 261 provided on the second connecting plate 26. For example, the plurality of first connecting members 25 disposed at the end of the first prefabricated form are butted against the first connecting members 25 disposed at the head end of the second prefabricated form, and the plurality of fasteners pass through the second connecting holes 261 opposite thereto, respectively, thereby lengthening the prefabricated form 20. When the rest of the prefabricated forms 20 are still to be installed, the installation method is the same as the above operation, and will not be described herein again. Thus, an elongated prefabricated formwork is obtained, which meets the length requirements for the prefabricated capping beam.

Specifically, with reference to fig. 5 and 6, the prefabricated bottom form 21 further includes: the second mounting surface 211 and the side mold plate mounting locations 28 provided on both sides of the second mounting surface 221. The second mounting surface 211 is provided on a side close to the prefabricated sideform 22.

Preferably, the sideform mounting location 28 is a rounded table protruding from the second mounting surface 221. On the one hand, the sideform mounting position 28 makes the second mounting surface 211 transited from a horizontal mounting surface to a vertical mounting surface; on the other hand, the faces formed by the sideform mounting locations 28 provide for better mounting of the prefabricated sideforms 22 to the prefabricated base forms 21.

Furthermore, the side formwork mounting positions 28 are further provided with limiting blocks 27, and corresponding grooves are formed in the corresponding prefabricated side formworks 22. For example, when lifting the prefabricated sideforms 22, the recesses in the prefabricated sideforms 22 may be fitted with the stoppers 27 to enable the prefabricated sideforms 22 to be initially installed.

Preferably, the limiting block 27 includes, for example: a first stopper 271 and a second stopper 272. The first limiting block 271 is located on one side of the length of the sideform mounting position 28 away from the second mounting surface 211; the second stopper 272 is located on the side of the sideform mounting location 28 away from the width of the second mounting surface 211. For example, in the process that the prefabricated side formwork 22 is connected with the prefabricated bottom formwork 21 in a matched manner, the first limiting block 271 can limit the prefabricated side formwork 22 to move in a direction away from the length direction of the prefabricated side formwork; the second stopper 272 can restrict the movement of the prefabricated sideform 22 in a direction away from the width thereof.

Preferably, the shape of the prefabricated top formwork 23 can be the same as that of the prefabricated bottom formwork 21; the prefabricated side formworks 22 can be parallel panels, the two prefabricated side formworks 22 are respectively installed on the side formwork installation positions 28, and then the side formwork installation positions 28 on the prefabricated bottom formwork 21 are buckled on the two prefabricated side formworks 22, so that the prefabricated formworks 20 are spliced.

Preferably, the plurality of sideform positioning apparatus 30 comprises, for example: the first side template positioning device and the second side template positioning device. Wherein, first side form board positioner sets up and is close to one side of stopper 27, second side form board positioner locates the one side of keeping away from stopper 27, just first side form board positioner with second side form board positioner locates respectively on prefabricated side form board 22's both sides limit.

Further, the thread pitches on the first threaded rod and the second threaded rod on the first side template positioning device are smaller than the thread pitches on the first threaded rod and the second threaded rod on the second side template positioning device.

For example, when the prefabricated side die plate 22 is positioned and installed, one side of the prefabricated side die plate 22 close to the limiting block 27 can be preliminarily positioned through the limiting block 27, and deviation between the sides is small; however, the deviation between the sides far away from the limit blocks 27 is large, so that the screw pitches of the first threaded rod and the second threaded rod on the first side template positioning device are set to be small, and the side near the limit blocks 27 can be accurately adjusted; the screw pitches on the first threaded rod and the second threaded rod on the second side template positioning device are set to be larger, so that large deviation can be quickly adjusted, and time is saved.

Preferably, the prefabricated bottom form 21 further comprises, for example: a plurality of first stiffeners 61 and a plurality of second stiffeners 62. The first reinforcing pieces 61 are arranged on one side far away from the second mounting surface 211, and the first reinforcing pieces 61 are arranged along the length direction of the prefabricated bottom template 21; the second reinforcing members 62 are arranged on the side far away from the second mounting surface 211, and the second reinforcing members 62 are arranged along the width direction of the prefabricated bottom formwork 21; and the height of the second reinforcing members 62 is higher than that of the first reinforcing members 61, and a pad block mounting position is formed between the adjacent second reinforcing members 62.

For example, on the one hand, the plurality of first stiffeners 61 and the plurality of second stiffeners 62 are disposed on the side of the prefabricated bottom formwork 21 away from the second mounting surface 211, so that the prefabricated bottom formwork 21 can be prevented from being deformed when the prefabricated formwork 20 is poured; on the other hand, the first cushion block 40 and the second cushion block 50 can be enabled to slide relative to the first cushion block 40 and the second cushion block 50 when the prefabricated bottom template 21 is installed through the cushion block installation positions.
