Description

Technical Field

[0001] This invention relates to the field of concrete pouring formwork construction, and in particular to a concrete pouring formwork with an imitation wood grain texture and a construction method thereof. Background Technology

[0002] Fair-faced concrete is a construction technique that directly utilizes the natural texture of concrete after molding as a finishing effect. Due to its natural color, unique texture, and the fact that it does not require secondary decoration, it has gradually become a major choice for decoration, forming a unique architectural style, and has significant environmental advantages and long-term economic benefits.

[0003] The standard construction steps for fair-faced concrete are: formwork erection, application of release agent, reinforcement binding, concrete pouring, and formwork removal. To achieve a wood grain finish, the traditional method typically involves pre-fabricating rubber formwork with a wood grain texture. Due to the specific nature of the project, this formwork is generally a disposable material, resulting in high costs and a repetitive, unnatural texture. Chinese patent application number 202610185601.7 discloses an integrated casting formwork for steel-concrete composite column-beam structures. The formwork includes column formwork, a steel structure, and beam formwork. The column formwork is perpendicular to the ground and includes a first column formwork and a second column formwork, spaced apart. The steel structure includes a first steel column, a second steel column, and a steel beam. The first steel column is located inside the first column formwork, the second steel column is located inside the second column formwork, and the steel beam is located between the first and second steel columns. The beam formwork includes a first steel plate, a second steel plate, and a base plate. The first and second steel plates are fixedly connected to the two ends of the base plate, and the steel beam is located between the first and second steel plates. This invention solves the problems of low efficiency and difficulty in controlling positioning accuracy in traditional construction methods, and also solves the problem of adjusting the verticality of formwork connection nodes. However, this invention clearly cannot achieve the goal of directly forming wood grain or other textured patterns after concrete pouring. Summary of the Invention

[0004] Therefore, in response to the above problems, this invention proposes a concrete pouring template and construction method with imitation wood grain texture, which solves the technical problem that existing concrete pouring templates have a single style and function, and cannot directly form patterns and textures on the surface after the concrete is poured and formed, requiring subsequent construction processes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a concrete casting template with a wood grain texture, comprising a supporting base plate, an adhesive layer, a wood grain board, and a release agent layer, wherein the supporting base plate, the adhesive layer, the wood grain board, and the release agent layer are compositely formed; the supporting base plate is provided with a fastening connection structure for connecting adjacent supporting base plates; the supporting base plate is provided with an auxiliary coating mechanism for assisting in the addition and demolding of the adhesive layer and the release agent layer; the fastening connection structure includes components disposed on the supporting base plate at its edge. The support substrate includes a snap-fit ​​sub-part and a snap-fit ​​female-part, a snap-fit ​​groove on the outer surface of the support substrate, and a clamping plate inserted into the snap-fit ​​groove. Each support substrate has a snap-fit ​​sub-part and a snap-fit ​​female-part on its two opposite edges. The snap-fit ​​sub-part and the snap-fit ​​female-part are snap-fitted together. Adjacent support substrates are connected by snap-fitting the sub-part and the female-part. The snap-fit ​​groove is located at both sides of the support substrate. The clamping plate is reinforced by embedding its two ends into the snap-fit ​​grooves on the two adjacent support substrates.

[0006] Furthermore, the snap-fit ​​sub-part is an elongated snap-fit ​​protrusion that completely penetrates the support substrate along its length. The snap-fit ​​female part is an elongated snap-fit ​​groove that completely penetrates the support substrate along its length. The projections of the snap-fit ​​protrusion and the snap-fit ​​groove on the horizontal plane are both arc-shaped.

[0007] Furthermore, the projection of the snap-fit ​​groove onto the vertical plane is an inverted conical structure. The snap-fit ​​groove is provided with a snap-fit ​​surface, and snap-fit ​​protrusions are provided at intervals on the snap-fit ​​surface. The clamping plate fastens two adjacent support base plates by snapping with the snap-fit ​​protrusions.

[0008] Furthermore, the clamping plate is made of hard rubber.

[0009] Furthermore, a functional cavity is provided within the supporting substrate, and the auxiliary plating mechanism is disposed within the functional cavity. The functional cavity is a semi-enclosed cavity with a connecting through hole inside, which connects the functional cavity to the external space. The auxiliary plating mechanism includes a connecting support column, a vibrating pendulum wheel sleeved on the connecting support column, a traction rack that works in conjunction with the vibrating pendulum wheel, and a vibrating support bar that works in conjunction with the vibrating pendulum wheel. A guide channel is fixedly provided within the functional cavity, and the traction rack is inserted into the guide channel and moves upward. The extension extends through the connecting through hole to the outside of the support base plate. Traction teeth are regularly arranged on the traction rack. The vibrating pendulum is rotatably mounted on the connecting support column. The vibrating pendulum is driven to rotate by external force. A drive gear is provided on the vibrating pendulum. The traction teeth are connected to the vibrating pendulum by meshing with the drive gear. Several actuating rods are arranged around the vibrating pendulum. Several vibration slots are arranged at intervals on the vibrating support bar. The actuating rods and the vibration slots are connected in cooperation. The actuating rods are elastic rubber rods.

[0010] Furthermore, the guide channel is open at both ends and semi-open in the middle. An open groove is provided on the guide channel, which runs through the guide channel along its length. The guide channel is used to provide path limiting for the traction rack, and the traction rack meshes with the drive gear through the open groove.

[0011] Furthermore, the vibration slot has a hemispherical structure.

[0012] Furthermore, when the traction rack moves within the guide channel, the traction teeth on the traction rack mesh with the drive gear and drive the vibration swing wheel to rotate, and the actuating rod abuts against the vibration slot to make the vibration support bar vibrate.

[0013] A method for constructing concrete with a wood grain texture, which uses a wood grain textured concrete casting formwork, includes the following steps: S1. Purchase wood veneer; purchase a quantity of peach heartwood veneer with a thickness of 3MM and a length of 2500*1300MM; S2. Roller manufacturing; Designed wood grain embossing roller with a diameter of 300MM and a length of 1400MM; S3. Wood grain pressing: Place the peach heartwood veneer on a roller press to press out the wood grain, with a wood grain depth of 0.5MM-1MM; S4. Remove burrs from wood veneer; sand the heartwood veneer with wood grain to remove burrs, then apply a coat of primer to the veneer surface and polish it. S5, Wood veneer composite; Wood veneer with wood grain is glued to the baseboard using adhesive; S6, Template Composite: The baseboard with wood veneer is composited with the supporting substrate using a release agent; S7. Splicing the support substrate: Splice the support substrate into rectangular columns and pour cement. S8. Drying and demolding: After the poured cement has dried, dry and demold the supporting substrate.

[0014] Furthermore, in step S6, the traction rack is inserted into the support substrate to provide initial defoaming vibration to the support substrate. In step S7, after the cement is poured, the traction rack is removed to provide secondary defoaming vibration to the support substrate.

[0015] By adopting the aforementioned technical solution, the beneficial effects of the present invention are: 1. This invention proposes a concrete casting template with a wood grain texture. Compared with existing conventional concrete casting templates, its advantage lies in its ability to impart various textured patterns to smooth fair-faced concrete, creating a special decorative effect. The conventional fair-faced concrete construction steps are: formwork erection - application of release agent - reinforcement binding - concrete pouring - formwork removal. To achieve a wood grain finish, the traditional method usually involves pre-fabricating rubber templates with wood grain texture. Due to the special nature of the project, the templates are generally disposable materials, rubber templates are costly, and the repetitive textures are dull and unnatural. However, the casting template and construction method proposed in this invention can replace the wood veneer as needed to achieve various combination effects, and it has the effects of low cost and natural, non-repetitive textures. In this invention, the wood veneer is pre-composite to the supporting substrate, and then concrete slurry is poured. After demolding, the wood veneer is directly composited with the concrete to achieve a decorative effect on the outer surface of the concrete column.

[0016] 2. Regarding the splicing of the support substrates, this invention proposes a fastening connection structure to ensure a stable connection between two adjacent support substrates. This connection is primarily achieved through the engagement of a snap-fit ​​male part and a snap-fit ​​female part. The snap-fit ​​male part and the snap-fit ​​female part correspond to a snap-fit ​​protrusion and a snap-fit ​​groove, respectively. The snap-fit ​​engagement of the protrusion and groove ensures a stable connection on both sides of each support substrate. The groove connection method also improves the sealing of the template. Furthermore, the fastening connection structure in this invention also includes a snap-fit ​​groove and a clamping plate for enhanced connection. The snap-fit ​​groove and the clamping plate are also located at the edge of the support substrate. After the snap-fit ​​protrusion and the snap-fit ​​groove are snapped together, the clamping plate strengthens the two adjacent support substrates and improves the compressive strength of the long strip support substrate. The snap-fit ​​groove in this invention has an inverted conical structure. This design ensures that the connection between the two support substrates is tighter when the clamping plate is pressed down. At the same time, snap-fit ​​protrusions are provided on the snap-fit ​​groove to ensure that the clamping plate can be firmly connected to the snap-fit ​​groove. The clamping plate in this invention is made of hard rubber to avoid damaging the support substrate.

[0017] 3. The auxiliary coating mechanism proposed in this invention is used to ensure that no air bubbles are generated inside the support substrate during coating and concrete pouring. The defoaming method is vibration defoaming. The auxiliary coating mechanism is set in the functional cavity inside the support substrate. Since the support substrate is flexible in installation and is mostly used on construction sites, and since the support substrate is reused multiple times, a purely mechanical structure is used to achieve vibration, thereby improving the service life of the support substrate. Specifically, by pulling the traction rack, it drives the vibration swing wheel to rotate, and then the lever on the vibration swing wheel strikes the vibration slot to achieve the overall vibration of the support substrate. The traction rack provides two vibration drives to the support substrate when entering and leaving the support substrate. The two vibrations defoam the release agent and the poured cement slurry, respectively. At the same time, the traction rack can be pulled back and forth according to actual needs to achieve multiple vibration defoaming. In order to ensure high vibration efficiency, a guide channel is set to limit the stroke of the traction rack. When the stroke of the traction rack is standardized, the transmitted vibration is also regular.

[0018] 4. In the construction method of the present invention, the traction rack is pulled to drive the supporting substrate in steps S6 and S7 respectively, causing it to vibrate and thus perform defoaming. Attached Figure Description
