Technical Field
[0001] This utility model relates to the field of building formwork technology, and in particular to a steel formwork structure with adjustable gaps. Background Technology
[0002] Steel formwork, also known as (removable formwork mesh), can replace wooden formwork, significantly reducing the pressure on pore water and air bubbles in concrete compared to traditional formwork such as wood, plywood, or steel plates. After the concrete of the steel formwork (removable formwork mesh) structure is poured and formed, an ideal rough interface is created.
[0003] A search of Chinese Patent Publication No. CN219794630U reveals an adjustable-gap steel formwork structure, comprising: four steel formworks, each with a sub-steel formwork fixedly installed on one outer wall; and an adjustment component on each corresponding steel formwork. The adjustment component includes a slide rail, a slider, a deformation groove, a rubber block, a sliding channel, a connecting block, and a limiting plate. The slide rail is located at the top of the steel formwork, and the slider is slidably installed within it. The deformation groove is located at the top of the steel formwork and communicates with the slide rail. The rubber block is fixedly installed on one outer wall of the slider. The sliding channel is located on one outer wall of the steel formwork and communicates with the deformation groove. The connecting block is slidably installed within the sliding channel and is fixedly connected to one outer wall of the corresponding sub-steel formwork. This adjustable-gap steel formwork structure offers the advantages of adjustable gap and prevention of rubber block corrosion.
[0004] However, in implementing the relevant technology, the above-mentioned adjustable gap steel formwork structure has the following problems: In the above technical solution, the deformation groove is sealed by the sealing plate to prevent the rubber block from being contaminated with mortar or concrete. However, the bottom of the sealing plate lacks a sealing effect and is only limited by the plug-in method, which leads to the problem that the rubber block can still be contaminated with mortar or concrete. Based on this, this utility model designs an adjustable gap steel formwork structure to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a steel template structure with adjustable gaps to solve the problem mentioned in the background art that the bottom of the sealing plate lacks sealing effect and is limited only by plugging, resulting in the rubber block still being contaminated with mortar or concrete.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a steel template structure with adjustable gap, comprising a template body, a sub-template fixedly installed on one side of the template body, and a gap adjustment component penetrating one side of both the template body and the sub-template;
[0007] A deformation groove is provided on one side of the template body, and a rubber block is inserted into one side of the inner wall of the deformation groove;
[0008] A limiting plate is fixedly installed on one side of the template body, a blocking plate is detachably connected to the top of the limiting plate, and a sealing element is fixedly installed at the bottom of the blocking plate.
[0009] A limiting component is fixedly installed at the bottom of the blocking plate, and the outer side wall of the limiting component is connected to a fastener by a thread.
[0010] As a preferred embodiment, the gap adjustment assembly includes a bidirectional threaded rod and a nut. The bidirectional threaded rod is movably connected through one side of the template body and the sub-template, and the nut is threadedly connected to the outer wall of the bidirectional threaded rod.
[0011] As a preferred embodiment, the limiting component is a screw, and the fastener is a threaded block.
[0012] As a preferred embodiment, a connecting plate is fixedly installed on one side of the sub-template, and the two sides of the connecting plate are slidably connected to the two sides of the inner wall of the deformation groove.
[0013] As a preferred embodiment, a T-shaped block is fixedly installed on one side of the rubber block, and a T-shaped groove is formed on one side of the inner wall of the deformation groove, with the T-shaped block and the T-shaped groove being inserted into each other.
[0014] As a preferred embodiment, a limiting groove is formed through the top of the limiting plate, and a limiting rod is fixedly installed at the bottom of the blocking plate, with the limiting rod being inserted into the limiting groove.
[0015] As a preferred embodiment, the top of the limiting plate is provided with a fixing groove.
[0016] The technical effects and advantages of this utility model are as follows:
[0017] 1. By setting up a baffle plate, a seal, a fastener and a limiting component, the bottom of the baffle plate is inserted into the limiting plate, so that the limiting component passes through the limiting plate. The fastener is screwed onto the outer wall of the limiting component, and the baffle plate and the seal are in close contact with the top of the deformation groove, thereby further preventing the rubber block from being contaminated with mortar or concrete.
[0018] 2. By using the set bidirectional threaded rod and nut, rotating the nut on the bidirectional threaded rod adjusts the gap between adjacent template bodies and sub-templates. A smaller gap can prevent mortar from flowing out from the gap between them. When the mortar or concrete has a certain shape and is not easy to flow, the gap can be adjusted to be larger to accelerate the solidification of the mortar or concrete. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This utility model provides, for example Figure 1-4 The diagram shows an adjustable gap steel formwork structure, including a formwork body 1. A sub-formwork 2 is fixedly installed on one side of the formwork body 1. A gap adjustment component 3 is provided through one side of both the formwork body 1 and the sub-formwork 2. A connecting plate 9 is fixedly installed on one side of the sub-formwork 2. The two sides of the connecting plate 9 are slidably connected to the inner walls of a deformation groove 4. The connecting plate 9 and the deformation groove 4 can be pulled out and disassembled. By rotating the gap adjustment component 3, the gap between adjacent formwork bodies 1 and sub-formwork 2 can be adjusted. A deformation groove 4 is provided on one side of the formwork body 1. A rubber block 5 is inserted into one side of the inner wall of the deformation groove 4. When the gap between the formwork body 1 and the sub-formwork 2 decreases, the connecting plate 9 slides through the deformation groove 4 to press the rubber block 5. Deformation occurs within the deformation groove 4. A limiting plate 6 is fixedly installed on one side of the template body 1. A fixing groove 14 is provided through the top of the limiting plate 6. A blocking plate 7 is detachably connected to the top of the limiting plate 6. A sealing element 8 is fixedly installed at the bottom of the blocking plate 7. The sealing element 8 is a sealing gasket in the prior art. A limiting element 15 is fixedly installed at the bottom of the blocking plate 7. A fastener 16 is connected to the outer wall of the limiting element 15 by a thread. The limiting element 15 is a screw, and the fastener 16 is a threaded block. The limiting element 15 at the bottom of the blocking plate 7 is inserted into the fixing groove 14, and the fastener 16 is screwed onto the outer wall of the limiting element 15, so that the blocking plate 7 and the sealing element 8 are tightly attached to the top of the deformation groove 4, preventing the rubber block 5 from being contaminated with mortar or concrete.
[0026] In this embodiment, as Figure 1As shown, the gap adjustment assembly 3 includes a bidirectional threaded rod 31 and a nut 32. The bidirectional threaded rod 31 is movably connected to one side of the template body 1 and the sub-template 2. The nut 32 is threaded to the outer wall of the bidirectional threaded rod 31. By rotating the nut 32 on the bidirectional threaded rod 31, the gap between adjacent template bodies 1 and sub-template 2 can be adjusted.
[0027] In this embodiment, as Figure 4 As shown, a T-shaped block 11 is fixedly installed on one side of the rubber block 5, and a T-shaped groove 10 is provided on one side of the inner wall of the deformation groove 4. The T-shaped block 11 and the T-shaped groove 10 are interlocked. The interlocking of the T-shaped block 11 and the T-shaped groove 10 facilitates the disassembly and replacement of the rubber block 5.
[0028] In this embodiment, as Figure 2 and Figure 4 As shown, a limiting groove 12 is opened through the top of the limiting plate 6, and a limiting rod 13 is fixedly installed at the bottom of the blocking plate 7. The limiting rod 13 is inserted into the limiting groove 12. The limiting rod 13 at the bottom of the blocking plate 7 is inserted into the limiting groove 12, so that the blocking plate 7 is limited on the limiting plate 6.
[0029] The working principle of this utility model is as follows: This utility model is a steel template structure with adjustable gap. First, when in use, rotate the nut 32 on the bidirectional threaded rod 31 to make the connecting plate 9 slide and squeeze the rubber block 5 through the deformation groove 4.
