Embodiment 1

[0019] Example 1: Materials and Equipment

[0020] 1.1 Materials

[0021] 1.1.1 Use custom shaped steel formwork.

[0022] 1.1.2 When using the release agent, brush it evenly with a roller brush, and it must not flow, and it is strictly forbidden to contaminate the steel bars.

[0023] 1.1.3 See Table 1 for the construction material plan.

[0024] Table 1 Construction material schedule

[0025]

[0026]

[0027] Note: The unit is not specified in the table: mm: mm

[0028] 1.2 Mechanical equipment

[0029] Chainsaws, hand saws, hand hammers, wrenches, spirit levels, steel tapes, line sinks, etc. required by the project must be in good condition, and repairs should be made in time if there are problems to ensure the needs of the project.

Embodiment 2

[0030] Example 2: Quality Control

[0031] 2.1 All the preparatory work before construction should be ready, and the machinery and equipment can work normally after inspection without hidden dangers.

[0032] 2.2 The commercial concrete used has a factory certificate and a raw material test report, and the strength grade and other properties of the concrete meet the design requirements and construction specifications.

[0033] 2.3 When pouring concrete, the polluted steel bars should be dealt with in time, the displaced steel bars should be sorted and reset in time, and the operation horseway should be built in advance when pouring the roof concrete to ensure the safety of the operators.

[0034] 2.4 It is strictly forbidden to add water to the concrete, and the remaining concrete on the ground shall not be added to the newly poured concrete.

[0035] 2.5 The cloth is uniform and the blanking height is limited. The formwork is tightly seamed and must have sufficient rigidity...

Embodiment 3

[0040] Example 3: Security Measures

[0041] 3.1 Before the concrete is poured, the vibrator should be tested. The vibrator operator should wear rubber boots and insulating gloves; the vibrator should not be hung on the steel bar, and the wet hand should not touch the power switch.

[0042] 3.2 When pouring arc-shaped beams and cylindrical concrete, an operating table should be set up, and the operator should not stand directly on the formwork or support to avoid slipping or breaking the support and falling.

[0043] 3.3 All operators should wear safety helmets; safety belts should be worn for high-altitude operations, and sufficient lighting should be provided for night operations. Temporary electricity use at the construction site is strictly implemented in accordance with the relevant specifications of the "Technical Specifications for Temporary Electricity Use at Construction Sites" JGJ46-88.

Abstract

The invention relates to an adjustable arc-shaped beam cylindrical node assembling clamp and a construction method thereof. The arc-shaped clamp is formed by superposing halves of two steel plates which are 4mm thick and 100mm wide; a superposed part can adjust the width of the beam section at a beam cylindrical node and is fixed by a screw with the diameter of phi 12; one side of a steel plate which is 200mm wide is fixed on a node template, and the other side of the steel plate is fixed by an opposite-pull screw; two sides of a beam are symmetrically arranged; holes are formed in the steel plate which is 200mm wide along the length direction; two rows of large holes in the outer side are formed in a 45-degree angle manner and at intervals of 50mm; a row of small holes in the inner side are arranged at intervals of 100mm; the large holes in the outer side are formed by that a beam bottom and the node which have a height difference along the height direction of the beam are connected with each other; and the clamp can randomly adjust the intervals from the large holes in the outer side.

Description

technical field [0001] The invention relates to the field of building decoration. Background technique [0002] With the vigorous development of modern buildings, the shapes of large public buildings have become increasingly rich, novel and diversified. Therefore, in the construction of construction projects, the construction difficulty of structural joints such as curved beams and columns is becoming more and more complicated; with the continuous improvement of people's requirements for engineering quality and construction efficiency, the construction difficulty of curved beams and columns in special-shaped buildings is discussed and researched. : The traditional construction method adopts a narrow flat die to make a full-fold line assembly along the arc, and then uses a steel ring to hold the outer periphery to control the position. As a result, partial out-of-roundness appears, the appearance is wavy, and the molding quality is poor. The special production of shaped ste...
