Embodiment 1

[0032] This embodiment provides a composite formwork 1 that adopts an inner pull type without dismantling, such as figure 1 As shown, it includes a module inner board 101, a module outer board 102 and a module core board 103 arranged between the module inner board 101 and the module outer board 102. The module core board 103 is embedded with an inner puller 104, and the inner puller 104 A connection part 105 protruding from the module inner panel 101 is provided on the top, and a structural tie rod 106 is connected between the inner formwork and the outer formwork constituting the building wall, and the two ends of the structural tie rod 106 are respectively connected to the inner formwork and the outer formwork. The connecting portion 105 on the layer template, the two sides and the upper and lower sides of the module core board 103 are respectively provided with slots 107 or sockets 108 for splicing connection with other composite templates.

[0033] In this specific embodim...

Embodiment 2

[0036] On the basis of Embodiment 1, this embodiment provides a concrete cylinder wall, such as figure 2 , image 3 As shown, it includes the inner wall 2 and the outer wall 3, and the concrete pouring cavity 4 is between the inner wall 2 and the outer wall 3, and the inner wall 2 and the outer wall are all spliced ​​by the inner pull type non-detachable composite template 1 in the first embodiment. Since the wall of the cylinder is circular, the inner pull type non-disassembly composite formwork 1 is a curved formwork, and the inner wall of the cylinder and the outer wall 3 of the cylinder are connected by a structural tie rod 106, and the two ends of the structural tie rod 106 are respectively connected to the inner pull On the connection part 105 of the non-disassembly composite formwork 1.

Embodiment 3

[0038] This embodiment provides a construction method for the concrete cylinder wall in Embodiment 2, specifically as follows:

[0039]1) After the foundation construction of the cylinder body is completed, before the construction of the cylinder body, the contact surface between the cylinder body foundation and the cylinder body should be chiseled and cleaned. The central control piles should be manufactured and installed and marked for protection. After the binding steel bars are concealed and accepted, support The inner-pull non-dismantling composite formwork 1, after the inner-pull non-dismantling composite formwork 1 is supported to the pouring height, the concrete is poured, and after the first layer of concrete is poured and reaches a certain strength, the upper second layer of concrete is poured Pouring construction, repeating this cycle until the cylinder body is poured to the top;

[0040] 2) Assemble the inner wall 2 and the outer wall 3 of the cylinder body with th...

Abstract

The invention discloses a concrete cylinder wall adopting an inner pulling type disassembly-free composite formwork and a construction method thereof.The formwork comprises a module inner plate, a module outer plate and a module core plate arranged between the module inner plate and the module outer plate, an inner pulling piece is pre-buried in the module core plate, and a connecting part protruding out of the module inner plate is arranged on the inner pulling piece; structural pull rods are connected between the inner-layer formwork and the outer-layer formwork which form the building wall body, the two ends of each structural pull rod are connected with connecting parts on the inner-layer formwork and the outer-layer formwork respectively, and the two sides, the upper side and the lower side of the module core plate are provided with inserting grooves or inserting openings used for being connected with other composite formworks in a spliced mode respectively. The concrete cylinder wall comprises a cylinder inner wall and a cylinder outer wall, a concrete pouring cavity is formed between the cylinder inner wall and the cylinder outer wall, and the cylinder inner wall and the cylinder outer wall are each formed by splicing a plurality of inner pulling type disassembly-free composite formworks. The construction efficiency can be greatly improved, the construction period is shortened, the quality and safety are guaranteed, and the selectable space of the exterior facing is large.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a concrete cylinder wall adopting an inner pull type non-detachable composite formwork and a construction method thereof. Background technique [0002] At present, for the cast-in-place concrete construction of circular structures such as fan barrels, chimneys, water towers, storage cabins, etc., the traditional construction technology of turning over formwork or sliding form has the characteristics of slow construction progress, long period, unstable quality and safety performance, The outer finish can choose the defect of small space. Contents of the invention [0003] The purpose of the present invention is to provide a concrete cylinder wall and its construction method using an internal pull-free composite formwork, so as to solve the problems in the above-mentioned prior art, the construction efficiency can be greatly improved, the construction period can ...
