Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building engineering, especially a building template. BACKGROUND

[0002] With the progress of building technology and the continuous acceleration of building speed, the previous brick laying wall building method is gradually replaced by the one-time concrete pouring method, which saves cost and time and has high firmness and strength. At present, some concrete blocks need to use building templates when adopting concrete pouring forming.

[0003] The building template is a temporary supporting structure, which is made according to the design requirements, so that the concrete structure and member are shaped according to the specified position and geometric size, the correct position is maintained, the self weight of the building template and the external load acting on it are borne, so that the concrete engineering quality, construction safety, construction progress and engineering cost are ensured.

[0004] However, the concrete will be bonded with the building template after drying, which makes it difficult to demold the building template. Generally, people will demold by knocking the building template to produce vibration, but this method will cause damage to the building template and the demolded concrete plate. SUMMARY

[0005] Therefore, the utility model aims at providing a building template to avoid damage to the building template and the demolded concrete plate.

[0006] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0007] A building template comprises a bottom plate, two first template bodies arranged oppositely on the bottom plate, and a plurality of second template bodies arranged between the two first template bodies, wherein the two first template bodies, the plurality of second template bodies and the bottom plate form a pouring space for pouring concrete.

[0008] The bottom plate is provided with a first demolding assembly, which comprises a driving screw arranged on the bottom plate and extending along the length direction of the bottom plate, a sliding block slidingly arranged on the driving screw, and two connecting rods hingedly arranged on both sides of the length direction of the sliding block, and the other ends of the two connecting rods are hingedly arranged on the two first template bodies, respectively.

[0009] When the driving screw is driven to rotate, the sliding block slides along the extension direction of the driving screw, and the corresponding first template body is pushed by the two connecting rods, so as to realize the separation of the first template body and the concrete.

[0010] Further, the first demolding assemblies are symmetrically arranged along the length direction of the bottom plate, and the bottom plate is provided with first mounting brackets corresponding to the first demolding assemblies; each driving screw is rotatably connected to the corresponding first mounting bracket.

[0011] Further, a transmission assembly is arranged between the two driving screws, and the transmission assembly is used for synchronously rotating the two driving screws; the transmission assembly comprises transmission belts arranged on the driving screws, and a transmission shaft connected between the transmission belts.

[0012] Further, the bottom plate is provided with support assemblies corresponding to the first mold plate bodies; each support assembly is used for supporting the corresponding first mold plate body.

[0013] Further, each support assembly comprises a second mounting bracket arranged on the bottom plate, and a support rod screwed on the second mounting bracket; one end of the support rod is capable of abutting against the corresponding first mold plate body.

[0014] Further, each support rod is provided with a buffer pad at the end close to the corresponding first mold plate body; each support rod abuts against the corresponding first mold plate body through the buffer pad on the support rod.

[0015] Further, each first mold plate body is provided with a limiting groove corresponding to the second mold plate body adjacent to the first mold plate body; each limiting groove is used for limiting the movement of the corresponding second mold plate body in the length direction of the bottom plate.

[0016] Further, each second mold plate body adjacent to the first mold plate body is clamped in the corresponding limiting groove through a clamping structure; each clamping structure comprises a clamping block slidingly arranged on the corresponding second mold plate body, an elastic member arranged between the clamping block and the corresponding second mold plate body, and a clamping groove arranged on the limiting groove and matched with the clamping block; the elastic member is used for abutting and pushing the clamping block to clamp in the clamping groove.

[0017] Further, the second demolding assemblies are arranged on each second mold plate body; each second demolding assembly comprises a threaded shaft screwed on the corresponding second mold plate body, and a flat plate embedded in the corresponding second mold plate body; one end of the threaded shaft is rotatably connected to the flat plate; the threaded shaft is used for driving the corresponding second mold plate body to separate from the concrete.

[0018] Further, each flat plate is made of plastic material; and / or, each first mold plate body and each second mold plate body is provided with a reinforcing rib.

[0019] Compared with the prior art, the building template has the following advantages:

[0020] The building template, through the setting of the driving screw, the sliding block and the connecting rod in the first demolding assembly, can make the two connecting rods push the corresponding first template main body and the concrete apart through the driving of the driving screw, thereby solving the problem that the operation personnel knocks the building template for demolding, resulting in damage of the building template and the demolded concrete plate.

[0021] Secondly, the first demolding assembly is arranged symmetrically in two, which can ensure that the first template main body is uniformly stressed, avoids unilateral stress concentration to cause deformation of the first template main body, and thus is beneficial to improving the stability of the demolding process.

[0022] Through the setting of the transmission assembly, synchronous rotation of the two driving screws can be realized when one of the driving screws is driven to rotate, thereby being beneficial to ensuring that the force applied to the first template main body is uniform and synchronous, and realizing stable separation between the first template main body and the concrete. Meanwhile, the transmission assembly is composed of a transmission belt and a transmission shaft, which is simple in structure, convenient to design and implement, and can reduce the manufacturing cost and maintenance cost of the equipment while meeting the synchronous rotation requirement.

[0023] Through the setting of the supporting assembly, the corresponding first template main body can be supported, the lateral pressure of the concrete on the first template main body is balanced, and the first template main body can be kept stable under the pressure of the concrete. The supporting assembly is composed of a second mounting bracket and a supporting rod, the supporting rod is connected with the second mounting bracket through threads, the extension length can be adjusted through rotation, the first template main body can be supported, and the stability of the first template main body can be ensured.

[0024] Furthermore, through the setting of the buffer pad, the abrasion between the supporting rod and the first template main body can be reduced, the concentrated load of the supporting rod can be converted into uniform pressure through elastic deformation to expand the contact area, and the local crushing of the first template main body caused by the direct abutting of the end of the supporting rod against the first template main body can be avoided, thereby being beneficial to prolonging the service life of the template. Through the setting of the limiting groove, the movement of the second template main body in the length direction of the bottom plate can be limited through physical fitting, the second template main body can be kept stable during concrete pouring, and the limiting groove can also provide a standardized docking interface for the corresponding second template main body to realize quick positioning of the second template main body.

[0025] The second template body is clamped in the limiting groove through a clamping structure, which can limit the movement of the second template body in the height direction, thereby facilitating the stability of the second template body. Meanwhile, the clamping structure is composed of a clamping block, an elastic member and a clamping groove, which is simple in structure and convenient to design and manufacture, and under the driving of the elastic member, the clamping block is continuously subjected to a pushing force, thereby ensuring that the clamping block and the clamping groove are always in close contact.

[0026] By screwing the threaded shaft on the second template body and through the rotary connection between the threaded shaft and the flat plate, the operator only needs to rotate the threaded shaft, which can drive the second template body to slide relative to the flat plate and separate from the concrete by using the principle of threaded transmission, thereby reducing the labor intensity of the operator and the time required for demolding, and thus facilitating the improvement of the demolding efficiency. Meanwhile, the rotary connection of the threaded shaft and the flat plate in combination with the mechanical advantage of the screwing structure can apply uniform lever force by rotating the threaded shaft, thereby realizing the gradual separation of the template and the concrete and effectively preventing the damage of the concrete.

[0027] Moreover, the flat plate is made of plastic material, which facilitates the reduction of manufacturing cost, and facilitates the demolding between the flat plate and the concrete. During demolding, the smooth surface can also reduce the adhesion and damage to the surface of the concrete, so that the surface of the concrete is more flat and smooth. Through the arrangement of the reinforcing ribs, the structural strength and rigidity of the first template body and the second template body can be enhanced, so that they can withstand greater load. Moreover, the reinforcing ribs can uniformly disperse the stress borne by the first template body and the second template body to the entire template structure, thereby avoiding local damage caused by stress concentration, and thus facilitating the improvement of the overall performance and durability of the first template body and the second template body.

[0050] The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0051] Embodiment one

[0052] The embodiment relates to a building template, which can solve the problem that the existing technology causes damage to the building template and the concrete plate demolded out of the building template by knocking the building template for demolding.

[0053] In the overall structure, in combination with the drawings shown in Figure 1 and Figure 2 The building template of the embodiment comprises a bottom plate 1, two first template main bodies 2 oppositely arranged on the bottom plate 1, and a plurality of second template main bodies 3 arranged between the two first template main bodies 2, and the two first template main bodies 2, the plurality of second template main bodies 3 and the bottom plate 1 form a pouring space 7 for pouring concrete.

[0054] ​The first demolding assembly 4 is arranged on the bottom plate 1, and the first demolding assembly 4 comprises a driving screw 41 arranged on the bottom plate 1 and extending along the length direction of the bottom plate 1, a sliding block 42 slidingly arranged on the driving screw 41, and two connecting rods 43 hingedly arranged on both sides of the length direction of the sliding block 42, and the other ends of the two connecting rods 43 are hingedly arranged on the two first template bodies 2. When the driving screw 41 is driven to rotate, the sliding block 42 slides along the extension direction of the driving screw 41, and the two connecting rods 43 push the corresponding first template bodies 2 to realize the separation of the first template bodies 2 and the concrete.

[0055] At this time, as arranged above, the driving screw 41, the sliding block 42 and the connecting rods 43 in the first demolding assembly 4 are arranged, and the two connecting rods 43 can push the corresponding first template bodies 2 to separate from the concrete by driving the driving screw 41, so that the problem that the building template and the concrete plate demolded from the building template are damaged due to the operation personnel knocking the building template for demolding can be solved.

[0056] It is worth mentioning that the number of the second template bodies 3 in the embodiment is two, and of course, in addition to being arranged as two, the number can also be designed and adjusted according to the actual pouring requirements of the concrete, for example, the number can be four, six, etc. Moreover, the hinged structures between the connecting rods 43 and the sliding block 42 and between the connecting rods 43 and the corresponding first template bodies 2 can be arranged according to the prior art, and will not be described here.

[0057] In the specific structure, the two first template bodies 2 are arranged at intervals along the width direction of the bottom plate 1, the two second template bodies 3 are located between the two first template bodies 2 and arranged at intervals along the length direction of the bottom plate 1, the two first template bodies 2 can clamp the two second template bodies 3, and the two first template bodies 2 and the two second template bodies 3 are distributed in a rectangular shape. After the two first template bodies 2, the two second template bodies 3 and the bottom plate 1 form a pouring space 7, the concrete is poured into the pouring space 7.

[0058] In the specific implementation, first, the bottom plate 1 is fixed by bolts to maintain the stability of the overall structure, and then after the concrete in the pouring space 7 is formed, the handle 44 on the driving screw 41 is operated to make the driving screw 41 rotate, so that the sliding block 42 slides on the driving screw 41 along the extension direction of the driving screw 41, and the two connecting rods 43 push the corresponding first template bodies 2 and the concrete to separate, and then the two second template bodies 3 are removed to complete the demolding of the concrete, so that the demolding can be realized without manual knocking, the time required for demolding is reduced, and the demolding efficiency is improved.

[0059] Based on the above overall introduction, in the embodiment, as a preferred exemplary structure, Figure 1 and Figure 2As shown in the figure, the first demolding assembly 4 is symmetrically arranged along the length direction of the bottom plate 1, and the bottom plate 1 is provided with a first mounting bracket 14 corresponding to each first demolding assembly 4, and each driving screw 41 is rotationally connected to the corresponding first mounting bracket 14.

[0060] Here, the first demolding assembly 4 is arranged as two symmetrical assemblies, which can ensure the uniform stress of the first formwork body 2 and avoid deformation of the first formwork body 2 caused by unilateral stress concentration, thereby improving the stability of the demolding process. At the same time, through the arrangement of the first mounting bracket 14, an installation position can be provided for each driving screw 41 to ensure the stable installation of the driving screw 41.

[0061] In specific implementation, the rotation of the two driving screws 41 can drive the corresponding sliding blocks 42 to slide and push the corresponding first formwork body 2 through the two connecting rods 43, thereby ensuring the stability of the separation of the first formwork body 2 from the concrete.

[0062] In order to facilitate the demolding operation of the operator, in the embodiment, as shown in the figure, Figure 2 As shown in the figure, a transmission assembly 411 is arranged between the two driving screws 41, and the transmission assembly 411 is used to synchronize the rotation of the two driving screws 41. Thus, through the arrangement of the transmission assembly 411, the rotation of one driving screw 41 can be synchronized with the rotation of the other driving screw 41, thereby ensuring the uniform and synchronous application of force to the first formwork body 2 and achieving the stable separation between the first formwork body 2 and the concrete.

[0063] At the same time, the transmission assembly 411 includes a transmission belt 4111 arranged on each driving screw 41 and a transmission shaft 4112 connected between the two transmission belts 4111. It can be understood that the transmission assembly 411 is composed of the transmission belt 4111 and the transmission shaft 4112, which has a simple structure, is easy to design and implement, and can reduce the manufacturing and maintenance costs of the equipment while meeting the synchronous rotation requirement.

[0064] In the specific structure, one transmission belt 4111 is arranged on one end of the driving screw 41 and the driving shaft, and the other transmission belt 4111 is arranged in the same way. A handle 44 is arranged on one driving screw 41, and the rotation of the corresponding driving screw 41 is driven by the handle 44. Under the transmission between the transmission belt 4111 and the transmission shaft 4112, the synchronous rotation of the two driving screws 41 is realized, thereby ensuring the uniform and synchronous application of force to the first formwork body 2 and achieving the stable separation between the first formwork body 2 and the concrete. It should be noted that the threads on the two driving screws 41 are arranged in opposite directions to realize the relative sliding of the two sliding blocks 42.

[0065] Furthermore, to ensure the stability of each first template body 2, in this embodiment, reference is made to... Figure 1 As shown, the base plate 1 is provided with support components 13 arranged corresponding to each first template body 2, and each support component 13 is used to support the corresponding first template body 2.

[0066] The advantage of this setup is that the support component 13 can support the corresponding first formwork body 2, balance the lateral pressure generated by the concrete on the first formwork body 2, and ensure that the first formwork body 2 remains stable under the concrete pressure.

[0067] Specifically, in this embodiment, as a preferred implementation, it still refers to... Figure 1 and Figure 3 As shown in the figure, each support component 13 includes a second mounting bracket 131 disposed on the base plate 1, and a support rod 132 screwed onto the second mounting bracket 131. One end of the support rod 132 can abut against the corresponding first template body 2.

[0068] Here, the support assembly 13 consists of a second mounting bracket 131 and a support rod 132. The support rod 132 is connected to the second mounting bracket 131 by a thread, and its extension length can be adjusted by rotation to support the first template body 2 and ensure the stability of the first template body 2.

[0069] In the specific structure, the base plate 1 includes a main body 11 and connecting parts 12 disposed on both sides of the main body 11 in the width direction. When the first template body 2 separates from the concrete, the first template body 2 will move along the width direction of the base plate 1 on the main body 11. In order to avoid the first template body 2, each of the second mounting brackets 131 in this embodiment is respectively installed on the corresponding connecting parts 12.

[0070] In practice, after pouring concrete into the pouring space 7, each support rod 132 is rotated to move towards the corresponding first template body 2 and press against the corresponding first template body 2 to support the corresponding first template body 2.

[0071] Furthermore, to avoid wear on the first template body 2 caused by the support rod 132, in this embodiment, the reference is continued. Figure 3 As shown, each support rod 132 is provided with a buffer pad 133 at one end near the corresponding first template body 2, and each support rod 132 abuts against the corresponding first template body 2 through its own buffer pad 133.

[0072] Here, the buffer pad 133 reduces wear between the support rod 132 and the first template body 2. Simultaneously, its elastic deformation expands the contact area, converting the concentrated load of the support rod 132 into a uniformly distributed pressure. This prevents localized crushing of the first template body 2 due to the end of the support rod 132 directly pressing against it, thus extending the template's service life. It should be noted that the buffer pad 133 in this embodiment can be made of rubber material well-known to those skilled in the art.

[0073] In addition, to ensure the stability of the second template body 3, in this embodiment, as follows: Figure 1 and Figure 4 As shown, each first template body 2 is provided with a limiting groove 21 corresponding to the adjacent second template body 3. Each limiting groove 21 is used to restrict the movement of the corresponding second template body 3 in the length direction of the base plate 1.

[0074] By setting the limiting groove 21, the movement of the second template body 3 in the length direction of the base plate 1 can be restricted by physical fitting, ensuring that the second template body 3 remains stable during concrete pouring. At the same time, the limiting groove 21 can also provide a standardized docking interface for the corresponding second template body 3, realizing the rapid positioning of the second template body 3.

[0075] In the specific structure, each limiting groove 21 extends along the height direction of the base plate 1. In specific implementation, after the two first template bodies 2 are placed, the two ends of each second template body 3 are inserted into the corresponding limiting groove 21 and slide along the extension direction of the limiting groove 21 to fix it between the two first template bodies 2. Then, each support rod 132 is driven to press against the corresponding first template body 2, thereby clamping each second template body 3.

[0076] This ensures the stability of each second template body 3. At the same time, the setting of the two ends of the second template body 3 in the corresponding limiting grooves 21 ensures the sealing of the pouring space 7, thereby preventing leakage of the poured concrete.

[0077] Meanwhile, in order to ensure the stability of the second template body 3 in the height direction, in this embodiment, as follows: Figure 4 and Figure 5 As shown, each second template body 3 adjacent to each first template body 2 is engaged in the corresponding limiting groove 21 by a snap-fit ​​structure 5. This arrangement, where the second template body 3 is engaged in the limiting groove 21 by the snap-fit ​​structure 5, restricts the movement of the second template body 3 in the height direction, thus ensuring the stability of the second template body 3.

[0078] It should be noted that in this embodiment, there are two second template bodies 3 arranged at intervals along the length of the base plate 1. Therefore, each second template body 3 has a snap-fit ​​structure 5 at both ends.

[0079] Each snap-fit ​​structure 5 includes a snap-fit ​​block 51 slidably disposed on the corresponding second template body 3, an elastic member 52 disposed between the snap-fit ​​block 51 and the corresponding second template body 3, and a snap-fit ​​groove 53 disposed on the limiting groove 21 and adapted to the snap-fit ​​block 51. The elastic member 52 is used to push the snap-fit ​​block 51 to snap into the snap-fit ​​groove 53.

[0080] It is understandable that the snap-fit ​​structure 5 consists of a snap-fit ​​block 51, an elastic element 52, and a snap-fit ​​groove 53. The structure is simple and easy to design and manufacture. Under the drive of the elastic element 52, a pushing force is continuously applied to the snap-fit ​​block 51 to ensure that the snap-fit ​​block 51 and the snap-fit ​​groove 53 always maintain close contact.

[0081] In the specific structure, combined with Figure 4 , Figure 5 and Figure 6 As shown, each of the two ends of the second template body 3 is provided with an elastic element 52 and a snap-fit ​​block 51, and each of the second template bodies 3 is provided with a groove 32 for the snap-fit ​​block 51 to slide. Each elastic element 52 is connected between the corresponding snap-fit ​​block 51 and the corresponding groove 32.

[0082] In specific implementation, each snap-fit ​​block 51 has an arc-shaped surface at one end near the corresponding limiting groove 21. When each second template body 3 slides down along the corresponding limiting groove 21, each snap-fit ​​block 51 will contact the bottom 211 of the corresponding limiting groove 21, and continue to slide down. Under the action of its arc-shaped surface, each snap-fit ​​block 51 will avoid the corresponding limiting groove 21, that is, each snap-fit ​​block 51 will slide into the corresponding groove 32.

[0083] When each of the second template bodies 3 slides to abut against the base plate 1, each locking block 51 aligns with its corresponding locking groove 53. At this time, driven by the corresponding elastic element 52, each locking block 51 is pushed out of its corresponding groove 32 and slides into the locking groove 53, completing the locking. It should be noted that the elastic element 52 in this embodiment can be an elastic product well known to those skilled in the art, such as a spring.

[0084] In addition, to prevent concrete damage, refer to Figure 1 and Figure 7 As shown, the building template in this embodiment also includes a second demolding component 31 disposed on each second template body 3. Each second demolding component 31 includes a threaded shaft 311 screwed onto the corresponding second template body 3 and a flat plate 312 embedded in the corresponding second template body 3. The surface of the flat plate 312 in contact with the concrete is flush with the surface of the corresponding second template body 3 in contact with the concrete, and one end of the threaded shaft 311 is rotatably connected to the flat plate 312. The threaded shaft 311 is used to drive the corresponding second template body 3 to separate from the concrete.

[0085] Therefore, by screwing a threaded shaft 311 onto the second template body 3 and through the rotational connection between the threaded shaft 311 and the plate 312, the operator only needs to rotate the threaded shaft 311 to drive the second template body 3 to slide relative to the plate 312 and separate from the concrete by utilizing the principle of thread transmission. This can reduce the labor intensity of the operator and reduce the time required for demolding, thereby improving demolding efficiency.

[0086] Meanwhile, the rotational connection between the threaded shaft 311 and the flat plate 312, combined with the mechanical advantages of the screw connection structure, allows for the application of uniform leverage force through rotating the threaded shaft 311, thereby achieving the gradual separation of the second template body 3 from the concrete and effectively preventing concrete damage.

[0087] It is worth mentioning that when the two second formwork bodies 3 are separated from the concrete, the operators directly remove the second formwork bodies 3, which will inevitably cause damage to the concrete, especially the corner parts. Therefore, this embodiment is equipped with a second demolding mechanism.

[0088] In specific implementation, such as Figure 8 As shown, each threaded rod has a protrusion 3111 at one end near the corresponding plate 312, and each plate 312 has an annular groove 3121 that matches the corresponding protrusion 3111. Each threaded rod rotates in the corresponding annular groove 3121 through the corresponding protrusion 3111. After the two first template bodies 2 separate from the concrete, the threaded shafts 311 on each second template body 3 are rotated, causing each second template body 3 to move relative to the corresponding plate 312. At this time, only each plate 312 is in contact with the concrete. After each second template body 3 separates from the concrete, the second template body 3 can be removed to achieve the separation of the plate 312 from the concrete.

[0089] Furthermore, since the contact area between the plate 312 and the concrete is small, the concrete will not be damaged when the plate 312 is removed, thus ensuring the integrity of the concrete molding.

[0090] In addition, to facilitate the separation of the plate 312 from the concrete, each plate 312 in this embodiment is made of plastic. The use of plastic for the plate 312 reduces manufacturing costs and facilitates separation from the concrete. During separation, the smooth surface also reduces adhesion and damage to the concrete surface, resulting in a smoother and more even concrete surface. It should be noted that the plate 312 in this embodiment can be made of plastic materials well known to those skilled in the art, such as polypropylene.

[0091] Furthermore, in order to strengthen the structural strength of each first template body 2 and each second template body 3, in this embodiment, as follows: Figure 1As shown, each of the first template bodies 2 and each of the second template bodies 3 is provided with reinforcing ribs 61. Here, by setting the reinforcing ribs 61, the structural strength and rigidity of the first template bodies 2 and the second template bodies 3 can be enhanced, enabling them to withstand greater loads.

[0092] Furthermore, the reinforcing rib 61 can evenly distribute the stress borne by the first template body 2 and the second template body 3 to the entire template structure, avoiding local damage caused by stress concentration, thereby improving the overall performance and durability of the first template body 2 and the second template body 3.

[0093] In this embodiment, the formwork is used by rotating the drive screws 41, causing the sliders 42 on each drive screw 41 to slide. Under the action of the connecting rod 43, the two first formwork bodies 2 separate from the concrete. Next, by rotating the threaded shafts 311, the two second formwork bodies 3 separate from the concrete, and then the two second formwork bodies 3 are removed, thereby achieving the separation of each flat plate 312 from the concrete. This solves the problem of damage to the formwork and the demolded concrete slabs caused by operators knocking on the formwork during demolding.

[0094] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
