Description

Technical Field

[0001] The utility model relates to the technical field of moulds for pouring floor decks, in particular to a mould for pouring concrete bottom mould steel bar truss floor decks. Background Art

[0002] Concrete-bottom-form steel truss floor decks are steel truss floor decks with concrete as the bottom formwork. They are widely used in floor slab construction. During construction, the concrete-bottom-form steel truss floor deck is used as the foundation, upon which concrete is poured. Since these concrete-bottom-form steel truss floor decks are fabricated in the factory, simple on-site hoisting, splicing, and a small amount of concrete pouring are required to complete the floor slab structure. This significantly shortens the construction period, reduces costs, and improves efficiency.

[0003] Because the concrete bottom formwork for the steel truss floor deck needs to be easily demoulded during factory casting, the molding surfaces of the side guards of the existing concrete bottom formwork for steel truss floor deck casting molds, i.e., the inner surfaces of the side guards, can only be configured as vertical surfaces or inclined surfaces with the upper portion tilted outward. As a result, both sides of the concrete bottom formwork for the steel truss floor deck after casting are configured as vertical surfaces or inclined surfaces with the upper portion tilted outward. When the two sides of the concrete bottom formwork are set in a vertical surface shape, since its end faces cannot be completely flat, the splicing between the concrete bottom formworks of two adjacent steel truss floor decks is relatively difficult. In many cases, it is even necessary to grind the sides of the concrete bottom formworks of the steel truss floor decks. When the two sides of the concrete bottom formwork are set in an inclined surface shape with the top facing outward, the splicing operation is relatively easy. However, after the two adjacent steel truss floor decks are spliced, there will be an inverted V-shaped splicing groove on the bottom surface. After the construction is completed and the formwork is removed, a large amount of splicing groove filling is required, which is very troublesome.

[0004] Therefore, the research purpose of this utility model is to design a mold for pouring concrete bottom formwork steel truss floor slabs that can not only effectively facilitate demoulding operations, but also effectively ensure that the poured product can be easily spliced ​​and reduce the amount of filling operations. Summary of the Invention

[0005] In response to the technical problems existing in the above-mentioned prior art, the present invention provides a mold for casting a concrete bottom formwork steel bar truss floor deck, which can effectively solve the technical problems existing in the above-mentioned prior art.

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

[0007] A mold for pouring a concrete bottom mold steel bar truss floor deck, comprising:

[0008] The mold body comprises a mold bottom plate with a horizontal top, and side baffles are fixed upwards on both sides of the mold bottom plate;

[0009] A molded convex strip, wherein the outer end surface of the molded convex strip is fixedly connected to the inner side surface of the side baffle, and the inner end surface of the molded convex strip is arranged in an inclined shape with the bottom facing outward;

[0010] A connection mechanism for detachably fixing the molded ridges on the side baffles;

[0011] Embedded connection mechanism, used to fix the formed convex strips to the side of the concrete bottom formwork steel truss floor deck.

[0012] A number of corresponding through holes are arranged side by side on the molded convex strip, and the embedded connection mechanism includes a rubber tube connected to the molded convex strip at the inner end of the through hole, and corresponding fixing rods are respectively inserted into the rubber tube, and the outer end of the fixing rod is provided with a corresponding hexagonal groove.

[0013] The mold bottom plate and the side baffle are formed by integrally molding plastic material.

[0014] The molded convex strip is made of rubber material, and the rubber tube is integrally molded and connected to the molded convex strip.

[0015] The inner side surface of the side baffle and the outer side surface of the formed convex strip are respectively arranged in a vertical plane shape.

[0016] The connection mechanism is an adhesive material layer, and the outer side surface of the molded convex strip is connected to the inner side surface of the side baffle through the adhesive material layer.

[0017] The connection mechanism is a double-sided tape, and the outer side surface of the molding convex strip is fixedly connected to the inner side surface of the side baffle through the double-sided tape.

[0018] The connection mechanism includes a plurality of positioning plates arranged at intervals, and the positioning plates are detachably mounted between the molding ridges and the top surface of the side baffles by means of a plurality of sets of locking screws.

[0019] Advantages of this utility model:

[0020] 1) The utility model adds a forming rib to the inner side surface of the side baffle of the mold body, wherein the inner end surface of the forming rib is arranged in the shape of an inclined surface with the bottom facing outward, and the forming rib is detachably fixed on the side baffle through a connecting mechanism. After casting and molding, the concrete bottom mold steel bar truss floor deck and the forming rib can be directly demolded from the mold body, thereby effectively facilitating the demoulding operation. Subsequently, the forming rib is detached from the concrete bottom mold steel bar truss floor deck, so that the two sides of the concrete bottom mold of the concrete bottom mold steel bar truss floor deck are inclined upward inward, and the two adjacent concrete bottom molds can form an upward V-shaped groove after the completion of the splicing, so that the concrete bottom mold steel bar truss floor deck can be easily spliced ​​and the amount of seam filling work can be reduced, and it can effectively facilitate the casting of the upper concrete layer.

[0021] 2) The present invention is also provided with a pre-embedded connection mechanism for fixing the formed ribs to the sides of the concrete bottom formwork steel bar truss floor decking. The pre-embedded connection mechanism includes a rubber tube connected to the formed ribs, and corresponding fixing rods are respectively inserted into the rubber tubes. Under the action of the pre-embedded connection mechanism, it is effectively ensured that the formed ribs can be stably fixed on the sides of the concrete bottom formwork steel bar truss floor decking after forming, so as to ensure that the formed ribs can be smoothly and synchronously demolded during the demoulding process; and the formed ribs can be effectively and stably fixed on both sides of the concrete bottom formwork steel bar truss floor decking after demoulding, so that the formed ribs can effectively form a buffer support for both sides of the concrete bottom formwork steel bar truss floor decking, so as to ensure that there are no excessive bumps and other problems during transportation, lifting, and splicing, thereby ensuring the practical effect of the present invention.

[0022] 3) After the concrete bottom formwork steel bar truss floor decking is demoulded, the fixing rod is driven outward by the corresponding hexagonal wrench. After the inner end of the fixing rod leaves the rubber tube, the rubber tube is set in a hollow state. In addition, it is a flexible and deformable material. In this way, the rubber tube can be torn off the concrete bottom formwork of the concrete bottom formwork steel bar truss floor decking at the same time as the forming convex strip is disassembled, thereby further ensuring the practical effect of the present invention.

[0023] 4) The inner side surface of the side baffle and the outer side surface of the molded convex strip of the utility model are respectively arranged in a vertical plane shape. Through the intervention of an adhesive material layer or a double-sided tape, the outer side surface of the molded convex strip can be conveniently fixed to the inner side surface of the side baffle. When demolding, the adhesive material layer or the double-sided tape can be directly destroyed, which is very convenient and low-cost.

[0024] 5) The connection mechanism of this utility model includes several spaced-apart positioning plates, which are removably mounted between the molding ribs and the top surface of the side panels using sets of locking screws. Before pouring, the locking screws and positioning plates cooperate to removably mount the molding ribs. After pouring, the locking screws and positioning plates are removed to complete the subsequent demolding process. This also prevents the subsequent cleaning of the mold body caused by the use of adhesive layers or double-sided tape. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the following embodiments and accompanying drawings:

[0034] Example 1

[0035] refer to Figure 1-4 A concrete bottom formwork steel bar truss floor deck casting mold, comprising:

[0036] The mold body 1 includes a mold base 101 with a horizontal top, and side baffles 102 are fixed upwards on both sides of the mold base 101;

[0037] A molded ridge 2, the outer end surface of the molded ridge 2 is fixed to the inner side surface of the side baffle 102, and the inner end surface of the molded ridge 2 is arranged in an inclined shape with the bottom facing outward;

[0038] The connecting mechanism 3 is used to detachably and fixedly mount the molding rib 2 on the side baffle 102;

[0039] The embedded connection mechanism 5 is used to fix the formed convex strip 2 to the side surface of the concrete bottom formwork steel bar truss floor deck 4.

[0040] The present invention adds a forming rib 2 to the inner side surface of the side baffle 102 of the mold body 1, wherein the inner end surface of the forming rib 2 is arranged in the shape of an inclined surface with the bottom facing outward, and the forming rib 2 is detachably fixed to the side baffle 102 by a connecting mechanism 3. After casting and molding, the concrete bottom mold steel bar truss floor deck 4 and the forming rib 2 can be directly demolded from the mold body 1, thereby effectively facilitating the demoulding operation. Subsequently, the forming rib 2 is detached from the concrete bottom mold steel bar truss floor deck 4, so that the two sides of the concrete bottom mold of the concrete bottom mold steel bar truss floor deck 4 are in the shape of an inclined surface with the upper part facing inward, and the two adjacent concrete bottom molds can form an upward V-shaped groove after the completion of the splicing, so that the concrete bottom mold steel bar truss floor deck 4 can be easily spliced ​​and the amount of seam filling work can be reduced, and it can effectively facilitate the casting of the upper concrete layer.

[0041] Several corresponding through holes 201 are arranged side by side on the molded ridge 2. The embedded connection mechanism 5 includes a rubber tube 501 on the molded ridge 2 connected to the inner end of the through hole 201. Corresponding fixing rods 502 are respectively inserted into the rubber tube 501. The outer end of the fixing rod 502 is provided with a corresponding hexagonal groove.

[0042] The mold bottom plate 101 and the side baffle 102 are integrally formed from plastic material. The molding ridge 2 is processed from rubber material, and the rubber tube 501 is integrally formed and connected to the molding ridge.

[0043] The present invention is also provided with a pre-embedded connecting mechanism 5 for fixing the formed convex strips 2 on the side of the concrete bottom formwork steel bar truss floor decking 4. Under the action of the pre-embedded connecting mechanism 5, it is effectively ensured that the formed convex strips 2 can be stably fixed on the side of the concrete bottom formwork steel bar truss floor decking 4 after forming, thereby ensuring that the formed convex strips 2 can be synchronously demolded smoothly during the demoulding process; and the formed convex strips 2 can be effectively and stably fixed on both sides of the concrete bottom formwork steel bar truss floor decking 4 after demoulding, so that the formed convex strips 2 can effectively form a buffer support for both sides of the concrete bottom formwork steel bar truss floor decking 4, to ensure that it does not cause excessive bumps and other problems during transportation, lifting, and splicing, thereby ensuring the practical effect of the present invention.

[0044] After the concrete bottom formwork steel bar truss floor decking 4 is demoulded, the fixing rod 502 is driven to move outward by the corresponding hexagonal wrench. After the inner end of the fixing rod 502 leaves the rubber tube 501, the rubber tube 501 is set in a hollow state. In addition, it is itself a flexible and deformable material. In this way, the rubber tube 501 can be torn off the concrete bottom formwork of the concrete bottom formwork steel bar truss floor decking 4 simultaneously during the disassembly process of the forming convex strip 2, thereby further ensuring the practical effect of the present invention.

The connecting mechanism 3 is an adhesive material layer, and the outer side of the molding ridge 2 is connected to the inner side of the side guard 102 through the adhesive material layer.

[0046] By intervening with the adhesive material layer, the outer side surface of the molded ridge 2 can be conveniently fixedly connected to the inner side surface of the side baffle 102. When demoulding, the adhesive material layer can be directly destroyed, which is very convenient and low-cost.

[0052] Before pouring, the forming ridge 2 is detachably installed by cooperating with the locking screw 302 and the positioning plate 301. After pouring, the locking screw 302 and the positioning plate 301 are removed to complete the subsequent demoulding operation, and it can prevent the increase in the subsequent cleaning workload of the mold body 1 due to the use of the adhesive material layer or double-sided tape.

[0053] It should be noted that the implementation principle and technical effects of this embodiment are the same as those of the first embodiment. For the sake of brief description, for matters not mentioned in this embodiment, reference may be made to the corresponding contents in the first embodiment.
