Abstract
Description
Technical Field
[0001] This utility model belongs to the field of template technology, and more specifically, it relates to a single template for wooden I-beams. Background Technology
[0002] Square column formwork is a mold used in building construction for pouring concrete columns. Square column formwork can be classified by material into wooden formwork, steel formwork, and plastic formwork, among which wooden square column formwork is the most common. Wooden square column formwork generally includes panels, back ribs, and clamps. In most cases, wooden square column formwork requires on-site assembly. Assembly typically involves first placing the panels, then placing back ribs at intervals on the back of the panels, and finally clamping the four panels together. This assembly process is very cumbersome and time-consuming, especially when installing the clamps. During assembly, workers need to frequently move and lift the clamps, which are mostly made of metal, making the labor intensity quite high. Summary of the Invention
[0003] The purpose of this utility model is to provide a single formwork for wooden I-beams to overcome the problem of cumbersome on-site assembly and construction of wooden square column formwork in the prior art.
[0004] This utility model is achieved using the following technical solution: a single template for a wooden I-beam, comprising a panel, on the back of which multiple vertically arranged wooden I-beams are installed at intervals along the width direction of the panel. Each wooden I-beam includes a front flange, a web, and a rear flange, with the web located between the front and rear flanges. The panel is fixedly connected to the front flange. Multiple clamping plates are installed at intervals along the height direction of the panel on the rear flange. The two sides of each clamping plate extend out of the panel, and clamping holes are provided on both sides of each clamping plate. A top plate and a bottom plate are installed on the upper and lower sides of the panel, respectively. An upper connecting hole and a lower connecting hole are provided on the uppermost and lowermost clamping plates, respectively.
[0005] Furthermore, the clamping hole is an elongated hole.
[0006] Furthermore, hooks on both sides are installed on the top of the uppermost clamping plate.
[0007] Furthermore, the clamping plate adopts a square tube structure.
[0008] Furthermore, the clamping plate is welded with multiple fixing plates at intervals along its length, and the fixing plates are fixedly connected to the rear flange of the wooden I-beam by bolts.
[0009] Furthermore, a rubber pad is installed on the top surface of the top plate.
[0010] Furthermore, the panel is fixedly connected to the front flange of the wooden I-beam by nails.
[0011] The single formwork template for the I-beams in this utility model can be used to assemble a square column formwork structure. The square column formwork structure includes a square column formwork assembly, which includes four of the aforementioned single formwork templates for the I-beams. The four single formwork templates for the I-beams formwork are arranged to form a square structure. In a square column formwork assembly, the clamps on two opposite single formwork templates are one-to-one and the two corresponding clamps are of the same height. The clamps on two adjacent single formwork templates are staggered. The two corresponding clamps on two opposite single formwork templates are fastened by tie bolts on both sides. The two ends of the threaded rods on the tie bolts pass through the clamping holes on the two corresponding clamps, and bolts are installed at the two ends of the threaded rods.
[0012] A square column formwork structure includes at least two square column formwork components, with two adjacent square column formwork components arranged vertically. The single wooden beam formworks on the two adjacent square column formwork components correspond one-to-one, and in the corresponding upper and lower single wooden beam formworks, the lower connecting hole of the upper wooden beam and the upper connecting hole of the lower wooden beam are aligned one-to-one. The two corresponding upper and lower single wooden beam formworks are connected by multiple fastening screws, which are sequentially inserted into the lower connecting hole on the upper single wooden beam formwork and the upper connecting hole on the lower single wooden beam formwork. Bolts are installed on the fastening screws.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] The single formwork for wooden I-beams described in this utility model integrates the panel, back rib, and plywood into a single unit, eliminating the need for piece-by-piece assembly on the construction site. Furthermore, during assembly, workers can use hooks to lift the single formwork for wooden I-beams. In summary, this utility model can accelerate the on-site assembly of square column formwork, simplify the assembly of square column formwork, and reduce the labor intensity of workers.

[0021] A single formwork for a wooden I-beam includes a panel 1, wherein the panel 1 is made of wood, specifically plywood or other materials.
[0022] Multiple vertically arranged wooden I-beams 2 are installed at intervals along the width direction of the back of the panel 1. Each wooden I-beam 2 includes a front flange 3, a web 4, and a rear flange 5, with the web 4 located between the front flange 3 and the rear flange 5, as shown in the attached figure. Figure 1 As shown, five wooden I-beams 2 are installed at intervals on the back of the panel 1.
[0023] The panel 1 is fixedly connected to the front flange 3, the front flange 3 of the wooden beam 2 is close to the panel 1, and the panel 1 is fixedly connected to the front flange 3 of the wooden beam 2 by nails.
[0024] The rear flange 5 is fitted with multiple clamping plates 6 at intervals along the height direction of the panel 1, such as... Figure 1 As shown, the panel 1 of this utility model has four clamping plates 6 spaced apart along its height. The clamping plates 6 are made of square tubing and stainless steel.
