Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction formwork technology, and in particular to a formwork for building construction. Background Technology
[0002] Steel formwork is a steel formwork used for concrete pouring and shaping. In addition to steel formwork, there are also wooden formwork, plywood formwork, etc. Steel formwork is widely used in construction because of its reusability and the aesthetically pleasing concrete pouring and shaping.
[0003] In building construction, steel formwork is often used to support concrete pavements. Traditional steel formwork requires the use of external screws and nuts to fix two adjacent steel formworks during installation. In addition, external support components are needed to support the steel formwork to improve the stability of the concrete pavement.
[0004] However, using external screws for fixing has several drawbacks. First, the installation efficiency is low. Second, the screws are easily lost when separated from the steel formwork. Furthermore, traditional supports are mostly fixed and cannot be adapted to the angle of the steel formwork or the slope of the roadbed. As a result, workers need to repeatedly replace the supports when fixing the steel formwork, which reduces work efficiency. Utility Model Content
[0005] The purpose of this utility model is to solve the problems in the prior art where fixing steel formwork with external screws easily leads to screw loss, and secondly, the support components are not convenient for adaptive support of the steel formwork. Therefore, a formwork for building construction is proposed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A formwork for building construction includes a steel formwork and further includes: a nut fixedly connected to the steel formwork, wherein the nut is internally threaded with a screw, one end of the screw passes through the steel formwork and is rotatably connected to a limit block, the steel formwork having a limit groove for cooperating with the limit block; and a positioning rod rotatably connected to the steel formwork, wherein the positioning rod has a support member, which provides adaptive support to the steel formwork when the positioning rod rotates.
[0008] For adaptive support of the steel formwork, preferably, the support includes a connecting rod slidably connected to the positioning rod, with a fixed seat rotatably connected to the end of the connecting rod away from the positioning rod, and a first torsion spring sleeved on the fixed seat, with the two ends of the first torsion spring fixedly connected to the fixed seat and the connecting rod respectively.
[0009] To further adjust the position of the connecting rod, a dovetail groove is provided on the positioning rod, and a dovetail block that is slidably connected to the connecting rod for rotation is provided in the dovetail groove.
[0010] To facilitate fixing the mounting base to the roadbed, the mounting base is further provided with insertion holes.
[0011] For positioning the fixed seat, preferably, at least two sets of elastic buckles are fixedly connected to the steel template, and the elastic buckles are fitted with insert rods that cooperate with the insertion holes.
[0012] In order to adjust the position of the positioning rod and increase the support range of the steel formwork, preferably, a slide rail is fixedly connected to the steel formwork, and a sliding block that is slidably connected to the slide rail and rotates with the positioning rod is slidably connected to the slide rail.
[0013] To further facilitate the repositioning and storage of the positioning rod, a second torsion spring is provided inside the sliding block, with both ends of the second torsion spring fixedly connected to the sliding block and the positioning rod, respectively.
[0014] To improve the stability of the steel formwork, preferably, the steel formwork is fixedly connected with reinforcing ribs, which are cross-shaped.
[0015] Compared with the prior art, this utility model provides a formwork for building construction, which has the following beneficial effects:
[0016] 1. This construction formwork, through the setting of support components, allows one end of the positioning rod to rotate and the position of the sliding connecting rod to adaptively position the steel formwork support, thereby improving the installation range of the steel formwork;
[0017] 2. The formwork used in this construction project, through the addition of reinforcing ribs, can improve the strength of the steel formwork and prevent deformation during use;
[0018] 3. The formwork for this building construction, through the setting of the second torsion spring, can reset and store the positioning rod, thereby improving the quality of steel formwork transportation.
[0019] The parts of this device not described herein are the same as or can be implemented using existing technology. This utility model uses screws threaded onto the steel template, which can prevent screw loss and improve the installation efficiency of two adjacent steel templates. Secondly, by using the cooperation of the support and positioning rod, the steel template can be self-adaptively supported and positioned. Furthermore, after the steel template is used, the positioning rod is reset by the second torsion spring, which can be stored and improve the transportation quality. Attached Figure Description

[0030] Example:
[0031] Reference Figures 1-7A formwork for building construction includes a steel formwork 1, and further includes: a nut 2, fixedly connected to the steel formwork 1, with a screw 3 internally threaded onto the nut 2. The screw 3 is an internal hexagonal screw 3, one end of which passes through the steel formwork 1 and is rotatably connected to a limit block 4. The steel formwork 1 has a limit groove 5 that cooperates with the limit block 4; a positioning rod 6 rotatably connected to the steel formwork 1; a slide rail 10 fixedly connected to the steel formwork 1; a sliding block 11 slidably connected to the slide rail 10 and rotatably connected to the positioning rod 6 for adjusting the lateral position of the positioning rod 6; a second torsion spring 12 inside the sliding block 11, with both ends of the second torsion spring 12 fixedly connected to the sliding block 11 and the positioning rod 6 respectively for adjusting the angle of the positioning rod 6; and a support member on the positioning rod 6, which provides adaptive support to the steel formwork 1 when the positioning rod 6 rotates.
[0032] Specifically, the screws 3 threaded onto the steel template 1 can prevent the screws 3 from being lost and improve the installation efficiency of two adjacent steel templates 1. Secondly, the support and positioning rod 6 work together to self-adaptively support and position the steel template 1. Furthermore, after the steel template 1 is used, the positioning rod 6 is reset by the second torsion spring 12, which can store it and improve the transportation quality.
[0033] The support includes a connecting rod 7 slidably connected to the positioning rod 6. The positioning rod 6 has a dovetail groove 73, and a dovetail block 74 slidably connected to the connecting rod 7 is rotatably connected in the dovetail groove 73 for adjusting the connecting rod 7. A fixed seat 71 is rotatably connected to the end of the connecting rod 7 away from the positioning rod 6. A first torsion spring 72 is sleeved on the fixed seat 71. The two ends of the first torsion spring 72 are fixedly connected to the fixed seat 71 and the connecting rod 7, respectively. An insertion hole 75 is provided on the fixed seat 71. At least two sets of elastic buckles 8 are fixedly connected to the steel template 1. The number of elastic buckles 8 is between two and four sets, preferably four sets. An insertion rod 9 that cooperates with the insertion hole 75 is snapped into the elastic buckle 8. The fixed seat 71 can be fixed by the cooperation of the insertion rod 9 and the insertion hole 75.
[0034] Specifically, by setting up the support components, one end of the positioning rod 6 is rotated and the position of the sliding connecting rod 7 is adjusted, which can adaptively support and position the steel formwork 1, thereby increasing the installation range of the steel formwork 1.
[0035] A reinforcing rib 13 is fixedly connected to the steel formwork 1. The reinforcing rib 13 is fixedly connected to the steel formwork 1 by welding. The reinforcing rib 13 is cross-shaped.
[0036] Specifically, by setting the reinforcing ribs 13, the strength of the steel formwork 1 can be improved, and deformation can be avoided during its use.
[0037] Working principle: When connecting two adjacent steel templates 1, the worker rotates the limiting block 4 horizontally so that it is inserted into the limiting groove 5 on one side of the other steel template 1. Then, the limiting block 4 is rotated vertically, and the screw 3 is turned with an Allen wrench. The screw 3 drives the limiting block 4 to move and press against the steel template 1, thus fixing the two adjacent steel templates 1. The screw 3 connected to the steel template 1 can improve the efficiency of disassembly and assembly, and also prevent the screw 3 from being lost.
[0038] When supporting and fixing the steel formwork 1, the worker pulls one end of the positioning rod 6 to rotate it. Then, the connecting rod 7 is pulled to slide on the positioning rod 6. After the connecting rod 7 and the positioning rod 6 are adjusted to the specified angle, the fixing seat 71 is rotated to abut against the roadbed. After the fixing seat 71 is pressed against the roadbed, the worker inserts the insertion rod 9 through the insertion hole 75 and inserts it into the roadbed to support and fix the steel formwork 1. At the same time, when used on roadbeds with different slopes, the angle between the positioning rod 6 and the connecting rod 7 can be adjusted to achieve self-adaptive support, thereby increasing the installation range of the steel formwork 1.
[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
