Description

Technical Field

[0001] The utility model relates to a composite plate strip fixing and hanging formwork device, belonging to the composite plate strip construction technical field. Background Art

[0002] During the construction of the composite floor, the precast panels are prefabricated in the factory in advance and then transported to the construction site. The precast panels are hoisted to the designated location by a crane and supported by brackets. Adjacent precast panels are spaced to form a plate strip, and the template is overlapped under the plate strip and fixed with a support frame. The support frame is spaced along the length of the template. After the template is installed, the steel bars are tied and the concrete is poured in place, so that the precast panels and the cast-in-place concrete form a composite floor.

[0003] Chinese patent CN219219845U discloses a composite plate strip reinforcement device, comprising a plurality of reinforcement structures evenly arranged along the extension direction of the composite plate strip, the reinforcement structure comprising a bottom reinforcement assembly arranged at the bottom of the composite plate strip and a top reinforcement assembly arranged at the top of the composite plate strip; the top reinforcement assembly comprises a transition support unit arranged at the top of the composite plate strip, two top support blocks both arranged at the top of the transition support unit, and a top reinforcement unit vertically arranged at the top of the top support block;

[0004] However, the following problems exist: the screws in the prior art extend far beyond the plate surface, which is not conducive to walking during construction and wastes materials, and the construction requires locking two screws; at the same time, the limit rod spans the transition block and the fixed block, and the span is too long; the prior art requires two building blocks, which are laborious to install and have low precision, and the transition block is prone to deviation during the reinforcement process; and it is easy to cause the pull rod to bend and deform, which in turn causes the plate strip hanging mold to deform. Utility Model Content

[0005] In order to solve the above-mentioned problems existing in the prior art, the utility model provides a composite plate strip fixing and hanging mold device, which can avoid the upper limit rod from causing disturbance deformation due to excessive span and the plate strip sinking caused by premature removal of the aluminum mold system.

[0006] The technical solution of the utility model is as follows:

[0007] A device for fixing and hanging molds for composite plate strips comprises a composite plate and a fixed template arranged on the lower side of the composite plate, comprising a plurality of H-shaped fixing blocks and fixing rods arranged on the top of the composite plates on both sides; the H-shaped fixing blocks span the composite plate strips, and an upper limit rod is arranged on the top of each H-shaped fixing block along the length direction of the fixed template, the top of the fixing rod is vertically penetrated through the fixed template and fixedly connected to the bottom of the upper limit rod, the bottom end of the fixing rod is provided with a fixing card for pressing against the bottom of the fixed template, and the fixing rod is also provided with a bolt for locking the fixing card.

[0008] Wherein, the bottom of the fixed template is provided with square wood arranged along the width direction of the fixed template.

[0009] Wherein, the fixing card is provided with a steel pipe along the length direction of the fixed template, and the top of the steel pipe is in close contact with the bottom of the square wood.

[0010] Wherein, a water stop plate is arranged at the middle end of the fixed rod, and the water stop plate is arranged in close contact with the surface of the fixed template.

[0011] Wherein, the H-shaped fixing blocks and the composite plates are both prefabricated with concrete of grade C30 strength.

[0012] The utility model has the following beneficial effects:

[0013] The utility model reduces the length of the upper limit rod by prefabricating an H-shaped fixing block on the composite plate, so that it does not need to span the width of the plate strip, thereby avoiding the upper limit rod from being deformed due to excessive span, thereby causing deformation of the composite plate, resulting in settlement, concrete pouring leakage and other problems.

[0014] The composite plate strip fixed formwork hanging device eliminates the need for vertical support of the template installation at the plate strip position, thereby improving construction efficiency. The device has strong turnover and can be reused, thus avoiding the plate strip sinking caused by premature removal of the plate strip due to the early removal of the aluminum formwork system.

[0019] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] See also Figure 1 to Figure 2 , the utility model provides a technical solution:

[0021] A composite plate strip fixed hanging formwork device, comprising a composite plate 1 and a fixed template 9 arranged at the lower side of the composite plate 1, comprising a plurality of H-shaped fixed blocks 7 and fixed rods 3 arranged at the top of the composite plates 1 on both sides; the H-shaped fixed blocks 7 span the composite plate 1 strip, and each H-shaped fixed block 7 is provided with an upper limit rod 6 at the top along the length direction of the fixed template 9, the top of the fixed rod 3 is vertically penetrated through the fixed template 9 and fixedly connected to the bottom of the upper limit rod 6, the bottom end of the fixed rod 3 is provided with a fixed card 2 for pressing against the bottom of the fixed template 9, and the fixed rod 3 is also provided with a bolt 4 for locking the fixed card 2;

[0022] A square wood 8 is arranged along the width direction of the fixed template 9 at the bottom of the fixed template 9, and a steel pipe 10 is arranged along the length direction of the fixed template 9 on the fixed card 2, and the top of the steel pipe 10 is close to the bottom of the square wood 8.

[0023] A water stop sheet 5 is arranged at the middle end of the fixed rod 3, and the water stop sheet 5 is arranged in close contact with the surface of the fixed template 9 to prevent the plate strip from generating cold seams due to the hanging template device, thereby causing leakage.

[0024] The H-shaped fixing block 7 and the composite plate 1 are both prefabricated with concrete grade C30 strength, and the composite plate 1 has a plate thickness of 60mm; the fixing card 2 is a butterfly nut, and the bolt 4 is screwed to the fixing card 2, which is used to fix the steel pipe 10 and tighten the hanging formwork system, and the fixing rod 3 is a 6mm diameter screw; the diameter of the bolt 4 is 6mm, which is used to fix the fixing rod 3 and the fixing card 2; the thickness of the water stop plate 5 is 7mm, which plays a water-stopping role; the upper limit rod 6 is specifically a steel bar with a diameter of 6mm, which is limited by the upper limit rod 6 and fastened to the H-shaped fixing block 7; the cross-section of the square wood 8 is 50mm×50mm; the plate thickness of the fixed formwork 9 is 18mm; the diameter of the steel pipe 10 is 48.3mm.

[0025] The H-shaped fixing block 7 interacts with the fixing card 2, so that the fixing card 2 supports the fixed template 9, and the two ends of the fixed template 9 are closer to the connected composite plate 1, thereby achieving the reinforcement effect of the fixed template 9 and improving the situation where leakage of slurry occurs between the fixed template 9 and the composite plate 1.

[0026] The steel pipe 10 is a double-jointed steel pipe, which is pressed against the square wood 8 through the fixing clamp 2 and the bolt 4; the fixing rod 3 applies an upward pulling force to the fixing clamp 2 through the bolt 4, and the upward pulling force is transmitted to the square wood 8 through the steel pipe 10, so that the square wood 8 plays a supporting role for the entire width direction of the fixed template 9. The square wood 8 changes the support of the fixing clamp 2 to the fixed template 9 from a point to a line, and the steel pipe 10 supports multiple square woods 8 arranged at intervals, so that the support of the fixing clamp 2 to the fixed template 9 changes from a line to a surface, that is, the square wood 8 and the steel pipe 10 are staggered, which increases the support range of the fixing clamp 2 to the fixed template 9.

[0027] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
