Description

TECHNICAL FIELD

[0002] In today's architectural structure construction design, when cast-in-place concrete is assembled using formwork, formwork reinforcement is a key link to ensure construction safety, improve work efficiency, and prolong the service life of the formwork. The purpose of reinforcement is to enhance the load-bearing capacity of the formwork, improve the overall stability, and avoid deformation or damage of the formwork during concrete pouring. Therefore, reinforcing materials such as steel pipes, steel bars, and connecting pieces are usually used to enhance the strength and stability of the formwork through techniques such as tie rod reinforcement, steel plate beam reinforcement, and reinforcement of connecting parts.

[0003] In the prior art, a modular wood formwork reinforcement structure is disclosed in Chinese Patent Application No. CN220150855U. The modular wood formwork reinforcement structure includes two oppositely arranged spliced formworks and a plurality of counter-pulling screw rods. The back of the spliced formwork is sequentially provided with a secondary back ridge and a primary back ridge. The spliced formwork includes a plurality of wood formworks and a strip-shaped steel form connected between adjacent two wood formworks. The strip-shaped steel form is a spliced strip-shaped steel form sequentially connected by a plurality of steel form splicing segments. The steel form splicing segment is a convex-shaped steel form provided with a recess on both sides. The primary back ridge is provided with a plurality of positioning cards for fixing the secondary back ridge. Each primary back ridge is provided with a plurality of screw rod perforations. The middle part of the steel form splicing segment is provided with a screw rod perforation.

The support unit comprises a main backrest 2, a secondary backrest 3 and a first connecting piece 4. The main backrest 2 is vertically arranged on one side of the template 1. Several first connecting pieces 4 are arranged on the side of the main backrest 2 away from the template 1, and several first connecting pieces 4 on the main backrest 2 are sequentially arranged on the same horizontal plane from top to bottom. The secondary backrest 3 is connected with several first connecting pieces 4 and the main backrest 2 on the same horizontal plane, and is perpendicular to the main backrest 2. In actual use, by arranging the main backrest 2 and the secondary backrest 3 on one side of the template 1, vertical and horizontal support forces are provided, which can significantly enhance the stability of the template 1 during concrete pouring, effectively prevent construction accidents caused by instability of the template 1, improve the safety of construction, and ensure the pouring quality of concrete, reduce the workload of later finishing, and thus improve the overall construction efficiency. Secondly, the secondary backrest 3 is stably connected with several first connecting pieces 4, which further reduces the difficulty of construction, simplifies the connection process, and enables construction personnel to more quickly and conveniently complete the installation and disassembly of the template. In addition, the design of the support unit is different from the traditional fixing connection between the backrest and the template through nails, thereby avoiding damage to the support unit and the template 1, and further improving the turnover rate of materials.

[0046] Preferably, the main backrest 2 is a hollow square steel pipe to provide stable support force, and facilitate subsequent assembly and processing.

[0047] Preferably, the main backrest 2 is uniformly provided with several through holes on the side away from the template 1 to stably install other components.

[0048] Preferably, the secondary backrest 3 is a wooden square to provide stable support force, reduce the weight of the overall reinforcing device, and provide good bending resistance to effectively disperse the pressure applied on the template 1 and reduce the risk of excessive local stress.

[0049] Preferably, the first connecting member 4 comprises at least three plates, wherein the first square plate 41 is detachably arranged on the side of the main backrest 2 away from the formwork 1 by means of bolts; the second square plate 42 is perpendicularly connected with the first square plate 41 and extends away from the formwork 1; the third square plate 43 is perpendicularly connected with the second square plate 42 and extends upward; the distance between the third square plate 43 and the first square plate 41 or the main backrest 2 is adapted to the size of the secondary backrest 3, so as to stably clamp the secondary backrest 3 by means of the first connecting member 4 or the first connecting member 4 and the main backrest 2, and ensure the structural stability. It can be understood that the perpendicularly connected positions of the three square plates of the first connecting member 4 are not only the end of the square plate, but also any position on the square plate, and the surfaces of the main backrest 2 connected with the first square plate 41 perpendicularly and / or parallel by the square plates are used to ensure that the secondary backrest 3 is perpendicular to the main backrest 2, and make the connecting member 4 adapt to the secondary backrest 3 of different sizes, so as to meet the design requirements.

[0050] In the optional embodiment, the first connecting member 4 further comprises a fourth rib plate 44, and the fourth rib plate 44 is perpendicularly connected with the first square plate 41 and the second square plate 42 on both sides, so as to ensure the structural stability of the first connecting member 4. It can be understood that the connecting position of the second square plate 42 and the first square plate 41 is not at the bottom end of the first square plate 41 at this time, so as to ensure the stable connection of the fourth rib plate 44 and the first square plate 41.

[0051] Specifically, as Figure 1 , Figure 2 and Figure 4As shown, the fastening units pass through and detachably connect with several support units and several templates 1 in horizontal direction, and connect with two support units in vertical direction to ensure the integrity and stability of the overall structure.

The first pair of pull rods 5 pass through two templates 1 and two main backrests 2, and detachably connect with two main backrests 2 through two first fasteners 6 respectively sleeved on both ends. Two mounting seats 7 are symmetrically arranged on the side of the main backrest 2 away from the template 1. The second pair of pull rods 8 pass through two mounting seats 7 on the side of two vertically adjacent main backrests 2 in sequence, and detachably connect with two mounting seats 7 through two second fasteners 9 respectively sleeved on both ends. In use, two main backrests 2 and two templates 1 are stably fixed in horizontal direction by the first pair of pull rods 5 and the first fasteners 6, thereby effectively resisting the huge lateral pressure generated during concrete pouring. Meanwhile, the vertically adjacent main backrests 2 are stably connected and fixed by the mounting seats 7, the second pair of pull rods 8 and the second fasteners 9, thereby forming multiple stable rectangular frames that can bear the weight of new poured concrete from above and effectively disperse lateral force, reduce local stress concentration, ensure the stability and safety of the overall structure, and avoid problems such as loosening of the template 1 during pouring. In addition, this modular design can significantly improve the adaptability of the reinforcing device and the template 1 to different operation requirements, and effectively improve the material turnover rate.

It can be understood that, after the first sleeve 61 is sleeved on the first pair of pull rods 5, the fastening head 62 can be conveniently sleeved outside the first sleeve 61 by clamping the third arc plate 6211 between two second arc plates 6112, and the second sleeve 621 is rotated through the handle 622, so that the outer side of the second arc plate 6112 contacts the inner side of the third arc plate 6211, thereby clamping the first pair of pull rods 5. Preferably, the arc length between two adjacent second arc plates 6112 along the arc line, the arc length of the second arc plate 6112, and the arc length of the third arc plate 6211 are all the same.

[0053] Preferably, the inner side of the first sleeve 61 and the first arc plate 6111 is provided with an internal thread matched with the first pair of pull rods 5, and the outer side of the second arc plate 6112 and the inner side of the third arc plate 6211 are provided with matching threads, so as to further improve the fastening effect.

[0054] Preferably, the second arc plate 6112 and the third arc plate 6211 are chamfered at both ends along the arc line, so as to improve the smoothness of the rotation of the fastening head 62 and improve the service life.

It can be understood that the bottom plate of the mounting seat 7 is provided with a plurality of through holes matched with the through holes on the surface of the main backrest 2, so that the mounting seat 7 and the main backrest 2 are detachably connected through bolts; secondly, the mounting of the mounting seat 7 can be carried out when the fixing of the formwork 1 is formally carried out, so as to improve the overall construction efficiency.

[0056] It can be understood that the first pair of pull screws 5 and the second pair of pull screws 8 are structurally identical, and the first fastener 6 and the second fastener 9 are structurally identical, thereby reducing the procurement cost and management complexity of spare parts, and improving the overall operation efficiency and maintenance convenience.

[0057] Specifically, as shown in Figure 1 、 Figure 2 and Figure 5 , the anti-seepage unit is arranged in the gap between the two formworks 1, for ensuring the flatness between the two formworks 1 and avoiding slurry leakage at the joint. The anti-seepage unit comprises a T-shaped sealing strip 10 and wedges 11. The middle sealing strip of the T-shaped sealing strip 10 is inserted into and passes through the gap between the two formworks 1, and the bottom plate thereof falls into the inner side of the formwork 1. The wedges 11 pass through the middle sealing strip of the T-shaped sealing strip 10 and are arranged on the outer side of the formwork 1.

Thirdly, during installation, the T-shaped sealing strip only needs to be inserted into the gap between the formworks, and then the wedges are used for pressure fixation, without the need for complex tools and a large amount of manual operation. In addition, since the wedges and the T-shaped sealing strip are standardized products, they are easy to purchase and manage, thereby further simplifying the construction process.
