Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a pipe concrete encapsulation template fixing structure. Background Technology

[0002] Existing patent documents disclose several solutions for fixing templates for concrete encapsulation of pipelines. These solutions mostly use tie rods to fix the templates. For example, utility model application CN202221998245.4 discloses a formwork structure for encapsulating municipal pipelines, including two templates. The two templates are set on a concrete cushion and located on both sides of the municipal pipeline, with gaps between the templates and the pipeline. The template is bracket-shaped and includes a vertical plate and a horizontal plate vertically fixed to the upper and lower ends of the vertical plate. The vertical plates of the two templates are arranged opposite each other, and each template is fixed to the concrete cushion by a pin. The two templates are fixedly connected by tie rods.

[0003] Although tie rods are a common method for fixing templates, they still have the following drawbacks:

[0004] 1. The tie rod itself needs to pass through the template, which requires damage to the template during use;

[0005] 2. The interaction between the tie rod and the template will cause localized stress concentration, while the reinforcement effect of the template plate far away from the tie rod is poor.

[0006] 3. Once the template is perforated, the fixing position of the tie rod becomes fixed and cannot be adjusted according to actual construction needs.

[0007] 4. After construction is completed, the removal of the tie rods is cumbersome, and the entire construction process is inefficient.

[0008] The applicant believes that the tie rod fixing technology is more suitable for building structures, while it is necessary to develop a new formwork fixing device for concrete encapsulation of pipes. Utility Model Content

[0009] This invention provides a new template fixing structure for concrete encapsulation of pipelines. Compared with the traditional tie rod fixing method, this fixing structure can effectively improve the assembly and disassembly efficiency and improve the template fixing effect. It can not only protect the template from damage, but also flexibly adjust the position of the fixed template according to the construction situation. The whole set of devices can be used for a long time.

[0010] To achieve the above objectives, the technical solution of this invention is as follows:

The template consists of two pieces, which are respectively located on both sides of the pipe to be encapsulated. Several horizontally arranged top beams are evenly distributed on the top of the template. A support beam is located below the top beam and on the outer surface of the template. The top of the support beam is detachably and fixedly connected to the top beam. Diagonal bracing assemblies are connected between the two ends of the top beam and the support beam. An adjustable auxiliary support assembly is connected to the diagonal bracing assembly.

[0012] Preferably, the outer surface of the template has several wooden joists arranged longitudinally, the wooden joists are fixedly connected to the template and fit tightly, and the support beam has several first positioning holes evenly distributed on it, and the support beam is fixedly connected to the wooden joists by screws passing through the first positioning holes.

[0013] Preferably, both the support beam and the top beam are made of H-beam steel. The top beam has several second positioning holes evenly distributed on it. The top of the support beam is fixed with a stud along the vertical direction. The stud passes through the corresponding second positioning hole and is locked with a nut.

[0014] Preferably, the diagonal bracing assembly includes a first diagonal brace and a second diagonal brace that are X-shaped and hinged to each other, with the two ends of the first diagonal brace and the second diagonal brace respectively fixedly connected to a first positioning hole or a second positioning hole.

[0015] Preferably, the adjustable auxiliary support assembly includes a first telescopic rod rotatably connected to the upper part of the rod body of the first diagonal brace and the second diagonal brace, respectively. One end of the first telescopic rod is rotatably connected to the outer wall of the first diagonal brace or the second diagonal brace, and the other end is fixedly provided with a connecting plate. The connecting plate is fixedly connected to the first positioning hole.

[0016] Preferably, the adjustable auxiliary support assembly further includes a second telescopic rod rotatably connected to the lower part of the first and second diagonal braces, respectively. One end of the second telescopic rod is rotatably connected to the outer wall of the first or second diagonal brace, and the other end is fixedly provided with a pad, which abuts against the construction ground.

[0017] Preferably, both the first telescopic rod and the second telescopic rod are equipped with a locking structure.

[0018] Preferably, a tapered structure for inserting into the ground is welded to the bottom end of the support beam.

Compared with the traditional tie rod fixing method, this fixing structure can effectively improve the efficiency of disassembly and assembly, and improve the template fixing effect.

This description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this invention.

[0030] In this embodiment, the novel pipe concrete encapsulation template fixing structure, such as... Figure 1-3As shown, the structure includes a template 9, a top beam 1, a support beam 7, and diagonal bracing components. Two templates 9 are respectively positioned on both sides of the pipe 10 to be encased. Several horizontally arranged top beams 1 are evenly distributed at the top of the template 9. Support beams 7 are located below the top beams 1 and on the outer surface of the template 9. The top of the support beam 7 is detachably fixed to the top beam 1. Diagonal bracing components connect the top beam 1 to the support beam 7 at both ends. Adjustable auxiliary support components are connected to the diagonal bracing components. The diagonal bracing components are used to distribute the force applied to the template by the concrete. The adjustable auxiliary support components can be positioned according to the construction conditions, and together with the diagonal bracing components, they share the force applied to the support beams by the template. The top beam spans the top of the two templates, and together with the two support beams, constrains the templates to a designated position.

[0031] In this embodiment, as Figure 1-3 As shown, several wooden joists 8 are arranged longitudinally on the outer surface of the template 9. The wooden joists 8 are fixedly connected to the template 9 and fit tightly. Several first positioning holes 13 are evenly distributed on the support beam 7. The support beam 7 is fixedly connected to the wooden joists by screws passing through the first positioning holes 13. The wooden joists can be replaced with steel joists, and the screws can be replaced with bolts. The fixed connection between the support beam and the wooden joists further secures the position of the template.

[0032] In this embodiment, as Figure 1-3 As shown, both the support beam 7 and the top beam 1 are made of H-beam steel. The top beam 1 has several evenly distributed second positioning holes 12, as shown... Figure 4 As shown, a stud 14 is fixed vertically at the top of the support beam 7, and the stud 14 passes through the corresponding second positioning hole 12 and is locked by a nut.

[0033] In this embodiment, as Figure 1-3 As shown, the diagonal bracing assembly includes a first diagonal brace 4 and a second diagonal brace 5 that are X-shaped and hinged to each other. The two ends of the first diagonal brace 4 and the second diagonal brace 5 are respectively fixedly connected to a first positioning hole or a second positioning hole. There are several ways to fix them together. For example, a threaded post 2 can be passed through the first or second positioning hole and then locked with a nut. Alternatively, a pin can be used to lock the heads (with insertion holes) of the first diagonal brace 4 and the second diagonal brace 5 that pass through the first or second positioning hole.

[0034] In this embodiment, as Figure 1As shown, the adjustable auxiliary support assembly includes a first telescopic rod 15 rotatably connected to the upper part of the rod body of the first diagonal brace 4 and the second diagonal brace 5 respectively. One end of the first telescopic rod 15 is rotatably connected to the outer wall of the first diagonal brace 4 or the second diagonal brace 5, and the other end is fixedly provided with a connecting plate (not shown in the figure). The connecting plate is fixedly connected to the first positioning hole 13. The fixing method can be selected in various ways, such as fixing it to the first positioning hole by bolts passing through the connecting plate.

[0035] In this embodiment, as Figure 1 As shown, the adjustable auxiliary support assembly also includes a second telescopic rod 16 rotatably connected to the lower part of the rod body of the first diagonal brace 4 and the second diagonal brace 5 respectively. One end of the second telescopic rod 16 is rotatably connected to the outer wall of the first diagonal brace 4 or the second diagonal brace 5, and the other end is fixedly provided with a pad 17. The pad 17 abuts against the construction ground, and the formwork support effect is improved by the reaction force of the ground.

[0036] In this embodiment, as Figure 1 As shown, both the first telescopic rod 15 and the second telescopic rod 16 are equipped with locking structures.

[0037] In this embodiment, as Figure 3 As shown, a tapered structure 18 for inserting into the ground is welded to the bottom end of the support beam 7.

[0038] In this embodiment, as Figure 1-3 As shown, the first and second diagonal braces are made of H-beams or angle steel.

[0039] The working principle of this new type:

[0040] 1. A novel formwork support system that eliminates the need for tie rods is achieved through a top beam, support beam, diagonal bracing components, and adjustable auxiliary support components. Since the formwork height for encasing pipe concrete is much lower than that for building formwork, and there are pipes inside, the tie rod fixing method cannot be fully utilized, and the fixing effect on the formwork is poor and it damages the formwork. Therefore, it needs to be improved. The improvement of this new model overcomes the shortcomings of the above-mentioned prior art.

[0041] 2. The top beam and support beam constitute the main frame of the formwork. On this basis, the lateral force applied to the formwork by the concrete can be dispersed by the diagonal bracing components, the vertical force can be dispersed by the support beams, and the weak parts of the formwork can be flexibly reinforced by the adjustable auxiliary support components, which fully ensures the stability of the formwork during the pouring process.

[0042] 3. When disassembling this new type of structure, it mainly involves disassembling three main parts: the main beam, the support beam, and the diagonal bracing assembly (on which an adjustable auxiliary support assembly is connected). The disassembly method is simple, does not interfere with the concrete, and is highly efficient. Conversely, when assembling this new type of structure, it is only necessary to build the frame of the main beam and the support beam, and then install the diagonal bracing assembly (on which an adjustable auxiliary support assembly is connected), which can also improve construction efficiency.
