Description

Technical Field

[0001] The utility model relates to a production mould for a laminated plate bottom plate, in particular to a highly enclosed side mould for producing the laminated plate bottom plate. Background Art

[0002] Composite floor is an assembled integral floor composed of prefabricated bottom plate and cast-in-place reinforced concrete layer. The prefabricated bottom plate is not only one of the components of the composite floor, but also a permanent formwork for the cast-in-place reinforced concrete composite layer. Horizontal equipment pipelines can be laid in the cast-in-place composite layer. Composite floor has good integrity and high rigidity, which can save formwork. The upper and lower surfaces of the plate are flat, which is convenient for finishing layer decoration. It is suitable for high-rise buildings and large-span buildings with high requirements for overall rigidity.

[0003] The prefabricated base plate is composed of a steel mesh and cast concrete. Some of the steel bars on the steel mesh extend from the cast concrete. The prefabricated base plate needs to be constrained by the side mold and the casting base plate during the casting and molding production process. The base plate is generally a horizontally fixed steel plate. The side mold can be arranged according to the preset size and fixed to the base plate by a magnetic box, thereby constraining a rectangular casting area. The side mold is generally divided into an upper and lower mold plate, which is used to clamp the steel bars at the edge of the steel mesh. At the same time, a gap is formed between the two mold plates. In order to prevent the concrete mortar from flowing out of the gap, a rubber strip is generally set between the two mold plates to fill the gap. The contact part of the rubber strip and the steel bar can deform adaptively to achieve clamping the steel bar while eliminating the gap generated in the mold closing part as much as possible. For this reason, people increase the weight of the upper mold to increase the pressure between the upper and lower membranes, thereby reducing the possibility of a gap in the mold closing part, but it also leads to a significant increase in the work intensity of carrying the upper mold. At the same time, there is a lack of positioning between the upper mold and the lower mold, and the mold closing accuracy is poor. Summary of the invention

[0004] The utility model provides a highly enclosed side mold for producing a laminated board bottom plate, which solves the problems of relatively large side mold mass and poor side mold closing precision in the prior art.

[0005] The above-mentioned technical problems of the utility model are mainly solved by the following technical solutions: a highly enclosed side mold for producing a composite board bottom plate, comprising a long straight bottom mold plate and a long straight top mold plate stacked on the upper side of the bottom mold plate, characterized in that: a lower rubber hose distributed along its length direction is fixed on the upper surface of the bottom mold plate, a plurality of pull rods vertically arranged upwards are also fixed on the upper surface of the bottom mold plate, an upper rubber hose facing and fitting with the lower rubber hose is fixed on the lower surface of the top mold plate, an opening penetrated by the pull rod is also provided on the top of the top mold plate, and a quick-release locking mechanism is detachably and rotatably installed on the top end of the pull rod, and the quick-release locking mechanism comprises a lever and an eccentric wheel fixed relative to the lever.

[0006] The usage of the utility model is similar to that of the existing side mold. First, the four bottom molds are combined and positioned according to the size of the product to be cast, and a rectangular casting area is constrained on the casting bottom plate. The bottom mold can be quickly fixed by a magnetic box; then the tied steel mesh is placed in the casting area, and the steel bars at the edge are placed on the lower rubber tube, and then the four top molds are placed on the bottom mold accordingly, and it is ensured that the pull rod cooperates with the opening. At this time, the bottom mold and the top mold are accurately positioned, and the head of the pull rod extends out of the opening part, and then the quick-release locking mechanism is installed on the head of the pull rod. When the quick-release locking mechanism forms a rotational fit with the top end of the pull rod, the eccentric wheel abuts against the upper surface of the top mold, and the lower rubber tube and the upper rubber tube are clamped on the upper and lower sides of the steel bar, but the clamping force is not enough to make the lower rubber tube and the upper rubber tube completely fit together. Therefore, it is also necessary to flip the lever to make it flip around the rotation axis and synchronously drive the eccentric wheel to rotate, thereby adjusting the spacing between the bottom mold and the top mold, so that the lower rubber tube and the upper rubber tube are completely fit together.

[0007] Furthermore, a straight cutout is provided at the position farthest from the rotation axis on the eccentric wheel. When the cutout on the eccentric wheel rotates to abut against the upper surface of the top template, when the eccentric wheel rotates to either side, the distance between the rotation axis and the upper surface of the top template will increase, thus achieving a self-locking effect.

[0008] Furthermore, the quick release locking mechanism also includes a rotating shaft body deviating from the center of the eccentric wheel, the eccentric wheel is provided with two and fixed to the two ends of the rotating shaft body in a mirror image, the top end of the pull rod is provided with an open groove, the upper opening of the open groove is provided with a downwardly protruding limit portion, and the rotating shaft body can form a rotational fit with the open groove. In this way, the quick release locking mechanism can be easily assembled or disassembled with the pull rod.

[0009] Furthermore, a screw-in seat corresponding to the tie rod is protruded on the upper surface of the bottom template, and the tie rod is screwed and fixed on the screw-in seat. The height of the tie rod can be fine-tuned by rotating the tie rod, so that the utility model is suitable for casting of composite slab bottom plates with more steel bar sizes.

[0010] Therefore, compared with the prior art, the utility model has the following characteristics: 1. The utility model realizes the locking of the top template and the bottom template through a quick-release locking mechanism, ensuring that the two rubber hoses are tightly fitted to the steel bars, eliminating the gap in the mold closing part, and at the same time, the pull rod cooperates with the opening, so that the bottom template and the top template are accurately molded, and the edge appearance of the product is better; 2. The assembly of the quick-release locking mechanism and the pull rod is a quick-release structure, which has the effect of convenient disassembly and assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Embodiment 1: A highly sealed side mold for producing a laminated bottom plate, comprising a long straight bottom mold plate 100 and a long straight top mold plate 200 stacked on the upper side of the bottom mold plate, the bottom mold plate and the top mold plate are both made of aviation aluminum material, a lower rubber tube 300 distributed along its length direction is fixed on the upper surface of the bottom mold plate, a plurality of pull rods 110 vertically arranged upwards are also fixed on the upper surface of the bottom mold plate, and the spacing between adjacent pull rods is between 40 and 80 centimeters, an upper rubber tube 400 facing and fitting with the lower rubber tube is fixed on the lower surface of the top mold plate, an opening 210 penetrated by the pull rod is also opened on the top of the top mold plate, a quick-release locking mechanism 500 is detachably and rotatably installed on the top end of the pull rod, and the quick-release locking mechanism comprises a lever 510 and an eccentric wheel 520 fixed relative to the lever;

[0022] The bottom of the lower rubber tube is integrally formed with a lower clamping strip 310 along its length direction, and the upper surface of the bottom template is provided with a lower clamping groove 120 along its length direction to match the shape of the lower clamping strip; the top of the upper rubber tube is integrally formed with an upper clamping strip 410 along its length direction, and the lower surface of the top template is provided with an upper clamping groove 220 along its length direction to match the shape of the upper clamping strip, and the outer contours of the two clamping strips are T-shaped;

[0023] The inner side surface of the top template is provided with a plurality of upper convex ribs 230 distributed along the length direction thereof, and the inner side surface of the bottom template is provided with a plurality of lower convex ribs 130 distributed along the length direction thereof.

[0024] The usage of this embodiment is similar to that of the existing side molds. First, the four bottom molds are combined and positioned according to the size of the product to be cast, and a rectangular casting area is constrained on the casting bottom plate. The bottom mold can be quickly fixed by a magnetic box; then the tied steel mesh is placed in the casting area, and the steel bars at the edge are placed on the lower hose. Then the four top molds are placed on the bottom mold accordingly, and it is ensured that the tie rod cooperates with the opening. At this time, the bottom mold and the top mold are accurately positioned, and the head of the tie rod extends out of the opening, and then the quick-release locking mechanism is installed on the head of the tie rod. When the quick-release locking mechanism forms a rotational fit with the top of the tie rod, the eccentric wheel abuts against the upper surface of the top mold, and the lower hose and the upper hose are clamped on the upper and lower sides of the steel bar, but the clamping force is not enough to make the lower hose and the upper hose completely fit. Therefore, it is also necessary to flip the lever around the rotation axis and synchronously drive the eccentric wheel to rotate, thereby adjusting the distance between the bottom mold and the top mold, so that the lower hose and the upper hose are completely fit.

[0025] Furthermore, the part of the eccentric wheel farthest from the rotation axis is provided with a straight cutout portion 521. When the cutout portion on the eccentric wheel rotates to abut against the upper surface of the top template, when the eccentric wheel rotates to either side, the distance between the rotation axis and the upper surface of the top template will increase, thus achieving a specific self-locking effect.

[0026] Furthermore, the quick release locking mechanism also includes a rotating shaft body 530 deviating from the center of the eccentric wheel, two eccentric wheels are provided and fixed to the two ends of the rotating shaft body in a mirror image, the top of the pull rod is provided with an opening groove 111, and the upper opening of the opening groove is provided with a downwardly protruding limiting portion 112, and the rotating shaft body can form a rotational fit with the opening groove. In this way, the quick release locking mechanism can be easily assembled or disassembled with the pull rod.

[0027] Furthermore, a screw-in seat 140 corresponding to the tie rod is protruded on the upper surface of the bottom template, and the tie rod is screwed and fixed on the screw-in seat. The height of the tie rod can be fine-tuned by rotating the tie rod, so that this embodiment is suitable for casting of composite slab bottom plates with more steel bar sizes.

[0028] It is obvious to those skilled in the art that the utility model can be changed in many ways, and such changes are not considered to be out of the scope of the utility model. All such modifications obvious to those skilled in the art will be included in the scope of the claims.
