Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a wall template positioning device which can prevent slurry leakage and protect electromechanical and electrical conduits. Background Art

[0002] With the continuous progress of society and the rapid development of urban construction, the limited urban space has led to the increasing prevalence of super-high-rise buildings. Because the shear walls of super-high-rise buildings are relatively thick, quality problems are prone to occur. The construction quality of the main structure is closely related to the positioning method of the inner wall formwork. The traditional positioning method of the inner wall formwork is to nail steel bar piles on the slab surface after the slab surface is cast. This method cannot see the specific position of the electromechanical and electrical conduits, so it is easy to nail them into the electromechanical and electrical conduits inside the slab, causing damage to the electromechanical and electrical conduits, and then resulting in blockage of the electromechanical and electrical conduits and inability to thread them later. At the same time, because the bottom of the inner wall formwork is flush with the slab surface, the problem of leakage at the bottom of the inner wall formwork is particularly prominent. Leakage can easily lead to honeycombed surface of the wall, affecting the casting quality, and the leaked slurry must be cleaned up in time, thereby increasing labor, material and machinery costs. Currently, the most common method for preventing slurry leakage at the bottom of interior wall formwork is to apply mortar to the bottom of the wall formwork and then wait for the mortar to reach a certain strength before pouring concrete. However, this method of preventing slurry leakage affects the project schedule due to the waiting time for the mortar to reach a certain strength. Moreover, applying mortar increases labor, material, and machinery costs, all of which increase project costs. In addition, this method of sealing often results in some slurry leakage during concrete pouring, causing quality problems. Therefore, this construction method is often less than ideal. Therefore, the positioning method of the interior wall formwork is crucial to ensure the quality of the main construction by comprehensively considering both preventing slurry leakage and protecting electrical conduits. Utility Model Content

[0003] The purpose of the present utility model is to provide a wall formwork positioning device that prevents leakage of mortar and protects electromechanical and electrical conduits. By using an L-shaped steel bar bracket, the inner wall formwork is clamped at the inner bottom of the U-shaped groove and the inner sides of the L-shaped positioning bars on both sides, thereby improving the subsequent formwork positioning accuracy. The formwork installation is faster and the construction progress is accelerated, avoiding the wall formwork being difficult to position, damaging the electromechanical and electrical conduits by positioning through nailing steel bar piles in the later stage, and leakage of mortar at the bottom during concrete pouring, which in turn leads to some rework and repair work, increasing construction costs. The positioning of the wall formwork is controlled by this device, which is simple and fast to operate, making the positioning and reinforcement of the wall formwork more accurate and convenient, accelerating the construction progress, and also greatly reducing the risk of rework, improving the efficiency of the inner wall formwork installation, the probability of qualified laying of electromechanical and electrical conduits in one time, and the quality of concrete forming, thereby solving the problems in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A wall formwork positioning device for preventing slurry leakage and protecting electromechanical and electrical conduit includes a steel bar bracket, two of which are symmetrically welded to a fixed cross bar and located on the same side of the fixed cross bar. The steel bar bracket is welded to the horizontal reinforcement of the structural plate through the fixed cross bar. The steel bar bracket is composed of long reinforcement, short reinforcement and connecting reinforcement. The bottom end of the long reinforcement and the bottom end of the short reinforcement are connected by the connecting reinforcement. The long reinforcement, short reinforcement and connecting reinforcement are in an "L"-shaped structure as a whole, and a U-shaped groove is formed between the long reinforcement, short reinforcement and connecting reinforcement.

[0006] Preferably, the long ribs are arranged facing each other, and the spacing between the long ribs is the thickness of the inner wall.

[0007] Preferably, a concrete slab is cast outside the fixed cross bar and the horizontal reinforcement of the structural plate, and the top surface of the concrete slab is flush with the top surface of the short reinforcement.

[0008] Preferably, the U-shaped groove is adapted to the template strip, and the thickness of the template strip is equal to the spacing between the long ribs and the short ribs.

[0009] Preferably, the U-shaped groove is adapted to the inner wall formwork, and the thickness of the inner wall formwork is equal to the spacing between the long reinforcement and the short reinforcement.

[0010] Preferably, the fixed cross bar, long ribs, short ribs and connecting ribs are made of threaded steel bars with a diameter of 12 mm.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. This utility model effectively solves the problems of difficult positioning and reinforcement of super-high-rise interior walls, easy leakage of slurry at the bottom of the interior wall formwork, easy damage to the mechanical and electrical conduits inside the board, and high construction costs. This device can obtain materials nearby at the construction site, effectively utilizing on-site resources, while also greatly reducing the risk of rework and reducing project costs.

[0013] 2. The present invention uses L-shaped steel bar brackets to clamp the inner wall formwork at the bottom of the inner side of the U-shaped groove and the inner side of the L-shaped positioning bars on both sides, thereby improving the subsequent formwork positioning accuracy. The formwork installation is faster and the construction progress is accelerated. It avoids the wall formwork being difficult to position, the damage to the mechanical and electrical pipes by positioning with steel bar piles in the later stage, and the leakage of slurry at the bottom during the concrete pouring process, which leads to some rework and repair work and increases construction costs. The positioning of the wall formwork is controlled by this device, which is simple and fast to operate, making the positioning and reinforcement of the wall formwork more accurate and convenient, accelerating the construction progress, and also greatly reducing the risk of rework, improving the efficiency of the inner wall formwork installation, the probability of qualified laying of mechanical and electrical pipes in one time, and the quality of concrete forming.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] In order to solve the problems existing in the prior art of difficult positioning and reinforcement of super-high-rise interior walls, easy leakage of slurry at the bottom of the interior wall formwork, easy damage to the mechanical and electrical conduits inside the slab, and high construction costs, the following technical solutions are proposed:

[0023] like Figure 3 As shown, a wall formwork positioning device for preventing slurry leakage and protecting mechanical and electrical conduits includes two steel bar brackets 2, which are symmetrically welded to the fixed crossbar 1 and located on the same side of the fixed crossbar 1. The steel bar brackets 2 are welded to the horizontal reinforcement 4 of the structural plate through the fixed crossbar 1. The upper surface of the steel bar of the fixed crossbar 1 is welded flush with the horizontal reinforcement 4 of the structural plate.

[0024] The steel bar support 2 is composed of long bars 21, short bars 22 and connecting bars 23. The bottom ends of the long bars 21 and the bottom ends of the short bars 22 are connected by the connecting bars 23. The long bars 21, short bars 22 and connecting bars 23 are "L" shaped as a whole.

[0025] like Figure 1As shown, 12 mm threaded steel bars are selected from the steel bar waste pool and bent to form a structure of long bars 21, short bars 22 and connecting bars 23. The length of the long bar 1 is an integer of 100, and the length of the steel bar raw material is L2, L2 = 100 + a + c + 2d, where a is the thickness of the template strip 3, c is the thickness of the plate surface protective layer, and d is the diameter of the steel bar.

[0026] The fixed cross bar 1 is also made of local materials. 12mm threaded steel bars are selected from the steel bar waste pool, and the diameter should not be too small to ensure that the steel bars have the necessary rigidity and are not easy to deform. Too large a diameter is wasteful and the cost is too high.

[0027] like Figure 4 As shown, the welding length of the fixed cross bar 1 and the horizontal reinforcement 4 of the structural plate is 10d for single-sided welding. Therefore, the distance from the inner end of the short reinforcement 22 to the fixed cross bar 1 is the single-sided welding length of 10d + the steel bar diameter d of the short reinforcement 22, which is 11d in total.

[0028] The long ribs 21 are arranged facing each other, and the spacing between the long ribs 21 is equal to the thickness b of the inner wall 8 .

[0029] The height of the short reinforcement 22 is equal to the thickness of the protective layer. After the concrete slab 6 is poured, the short reinforcement 22 is covered. The long reinforcement 21 plays the role of positioning and fixing the inner wall formwork 7 in the subsequent process, so it must be higher than the pouring surface of the concrete slab 6.

[0030] A U-shaped groove 5 is formed between the long reinforcement 21, the short reinforcement 22 and the connecting reinforcement 23. The U-shaped groove 5 is compatible with the formwork strip 3 and the inner wall formwork 7. The formwork strip 3 is made from local materials. A formwork strip 3 of a certain width is taken from the formwork waste. The width is recommended to be 100 mm. Before pouring, the formwork strip 3 is inserted into the U-shaped groove 5.

[0031] like Figure 5 As shown, after the concrete pouring is completed, the template strip 3 is taken out from the U-shaped groove 5, and the long reinforcement 21 is exposed on the surface of the concrete slab 6.

[0032] like Figure 6 As shown, the inner wall formwork 7 is then placed in the U-shaped grooves 5 on both sides and leaned against the long reinforcement 21. Since the inner opening distance between the two long reinforcements 21 is the thickness of the inner wall 8, the inner wall formwork 7 can be quickly positioned to ensure the cross-sectional size and position of the wall, and the mechanical and electrical conduits will not be damaged due to the subsequent nailing of steel bars. At the same time, since the inner wall formwork is stuck at the inner bottom of the U-shaped groove 5, and the U-shaped groove 5 has a certain depth, when pouring concrete for the inner wall 8, concrete will not leak from the bottom, so that the inner wall formwork 7 can be quickly positioned and its movement, leakage of slurry at the bottom, and damage to the internal mechanical and electrical conduits can be prevented.

[0033] The inner wall formwork 7 is reinforced and removed after the concrete is poured. To ensure that the original structure is not affected, the U-shaped groove 5 left by the removal is filled with fine stone concrete with a grade one higher than the concrete.

[0034] like Figure 2 As shown, in order to prevent the formwork strips 3 from deforming during the concrete pouring process and affecting the subsequent positioning, the longitudinal spacing of the assembly device on the inner wall 8 is equal to the spacing of the formwork reinforcement tension screws.

[0035] Working Principle: A fixed crossbar 1 and a reinforcement bracket 2 are constructed from on-site waste. The reinforcement bracket 2 is welded to the fixed crossbar 1 to form a complete assembly and secured to the slab's horizontal main reinforcement 4. Formwork strips 3 are then placed within the U-shaped grooves 5 of the reinforcement brackets 2. Once the concrete slab 6 is poured, the formwork strips 3 are removed, and symmetrical U-shaped grooves 5 are formed at the reinforcement brackets 2 on either side to secure the interior wall formwork 7. This series of steps allows for rapid positioning of the interior wall formwork 7, preventing leakage from the bottom and protecting electrical conduits from damage, thereby improving construction efficiency and reducing the risk of rework.

[0036] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
