Abstract

The invention provides a large-volume assembly type floor jig which is of a prefabricated structure and is formed by sequentially enclosing a plurality of vertically arranged formwork end to end in the circumferential direction, wherein the circumferential structure of the floor jig is the same as that of the side wall of an elevator shaft. The method solves the problems of low speed, large material consumption and high cost of the traditional brick moulding bed building method, greatly reduces the wet operation of a construction site, reduces the influence on the environment, and meets the requirement of green construction. Belongs to the technical field of building construction.

Description

Large-volume assembly type ground tire mold

Technical Field

The invention relates to a large-volume assembly type ground forming die, and belongs to the technical field of building construction.

Background

At present, basement foundation construction generally comprises the following two construction modes: firstly, the construction of brick brickwork brick bed-jig, the construction of traditional brick bed-jig directly carries out building of fragment of brick, carries out the work of plastering of brick wall again after the completion, and the construction cycle length just needs to satisfy the construction environment that can normally build by laying bricks or stones, and is comparatively harsh to the condition of construction. And secondly, the light concrete template is constructed, the construction adopts the standardized templates for splicing, the wet operation of site construction is reduced and the construction efficiency is improved compared with the brick masonry, but the construction mode is not suitable for construction of elevator shaft foundations, deep foundation pits and the like, and is only suitable for the standard middle and small square pile foundation bearing platforms.

The disadvantages of the above solutions are mainly manifested in: the bricks are adopted for building, the backfill amount of the earthwork excavation is large, the common mucky soil in the construction needs to be subjected to early treatment, and the construction environment is more limited. The construction progress is slow, and the fragment of brick piles up on the scene for a long time, occupies the place resource. After the wall is built, the wall body needs to be plastered, so that the wall body cannot be backfilled in time, the labor cost is high, and the construction period is prolonged. When meeting deep basal pit, for increasing brickwork stability itself, need increase the thickness of building bricks, lead to building by laying bricks or stones the material increase. The foundation ditch is darker, and constructor has certain potential safety hazard in the construction of inside, need adopt to support to consolidate, leads to the later stage to demolish and take time and take a lot of work. The light concrete template is adopted for construction, when a foundation pit is deep, the upper connecting part and the lower connecting part only depend on mortar, certain potential safety hazards are caused to constructors, corresponding reinforcing measures need to be added at the connecting parts, and therefore the construction procedures are increased. In order to increase the stability of the template, a laminated plate (double-layer or three-layer) form is required, so that the construction cost is increased by phase change. The construction adopts the layered construction, the construction is carried out by backfilling one layer, meanwhile, the interior needs to be synchronously supported for reinforcement, and the construction period is prolonged.

Disclosure of Invention

The invention aims to: the large-volume assembly type floor forming die is provided to solve the problems of low speed, large material consumption and high cost of the traditional brick forming die building method, greatly reduce wet operation of a construction site, reduce the influence on the environment and meet the requirement of green construction.

In order to solve the problems, the large-volume assembly type floor jig is supposed to be adopted, the floor jig is of a prefabricated structure and is formed by sequentially enclosing a plurality of vertically arranged templates end to end in the circumferential direction, and the circumferential structure of the floor jig is the same as that of the side wall of the elevator shaft.

In the assembly type ground forming die, the tongue-and-groove fit between two adjacent templates is combined and fixedly connected through split bolts;

in the assembly type floor mould, the template comprises two plane templates which are parallel to each other and are arranged oppositely and two U-shaped templates, the height of the plane templates is the same as that of the U-shaped templates, the two U-shaped templates are respectively arranged at two ends of the two plane templates, and two ends of the U-shaped templates are respectively fixedly connected with the same end of the two plane templates;

in the assembly type ground tire mold, the U-shaped template is formed by butting the upper part and the lower part, so that the weight of the single template is reduced, the hoisting is convenient, and if the template is an integral part, the weight of the template may exceed the hoisting bearing capacity.

Compared with the prior art, the method adopts the prefabricated components, and after stress analysis and checking, the components are disassembled under the condition of meeting the design standard. And according to the stress condition of each node, connecting in a mode of combining a bolt and a tongue and groove respectively. The construction and installation adopt the assembly type hoisting, and the whole process is operated by a dry method, so that the operation is convenient and fast; the floor mould is prefabricated in a factory, the surface effect of concrete after mould removal is excellent, and plastering engineering is not needed in the later period. The whole process is operated in a dry method, the mud is not dragged to carry water, and the requirement of green construction is met; adopt assembled hoist and mount, the construction is convenient, and is efficient, need not to set up unnecessary support, and hoist and mount are finished and can be backfilled, shortens construction cycle greatly.

Detailed Description

To make the objects, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings, and it should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

Examples

Referring to fig. 1 and 2, the embodiment provides a large-volume assembly type floor jig, which is of a prefabricated structure and is formed by sequentially connecting and enclosing a plurality of vertically arranged templates 1 end to end along the circumferential direction, the tongue-and-groove joints between two adjacent templates 1 are matched and fixedly connected through split bolts 2, the tongue-and-groove joints adopt a similar Z-shaped tenon-and-mortise structure, and the circumferential structure of the floor jig is the same as that of the side wall of an elevator shaft.

The template 1 comprises two plane templates 11 and two U-shaped templates 12 which are parallel to each other and are arranged oppositely, the height of the plane templates 11 is the same as that of the U-shaped templates 12, the two U-shaped templates 12 are respectively arranged at two ends of the two plane templates 11, two ends of the U-shaped templates 12 are respectively fixedly connected with the same end of the two plane templates 11, the U-shaped templates 12 are formed by butting an upper part and a lower part so as to reduce the weight of a single template and facilitate hoisting, and if the U-shaped templates are a whole part, the weight of the U-shaped templates may exceed the hoisting bearing capacity.
