Abstract

The invention discloses a reinforced concrete precast column vertical type prefabrication method and belongs to the technical field of construction engineering. According to the reinforced concrete precast column vertical type prefabrication method, a traditional precast column is turned in 90 degrees to carry out construction. The reinforced concrete precast column vertical type prefabrication method comprises steps as below: a steel pipe frame is used as a bed die supporting frame which is formed by cross rods and vertical rods, the bottom of the bed block is arranged inside the bed block board which is a steel mold board, and a side mold board is made of repeatedly-used waterproof bamboo plywood. Concrete precast column is poured. The side mold boards can be removed after the concrete precast column is finally set. The bed die supporting frame is removed. The reinforced concrete precast column vertical type prefabrication method has the advantages of changing a traditional horizontal type prefabrication method, saving membrane materials like bricks and mortars and the like, saving cost, and reducing pollutions, and the waterproof bamboo plywood can be used in a turnover mode.

Description

Prefabricated reinforced concrete post vertical prefabrication

Technical field

The present invention relates to a kind of reinforced concrete prefabricated column method for prefabricating, belong to construction engineering technical field.

Background technology

Prefabricated reinforced concrete column is adopted in the unproductive accessory building of coal mine ground as equipment canopy, storage facility, machine repair workshop, fully-mechanized mining equipment storehouse etc.At present, the horizontal prefabrication system of the many employings of job site prefabricated reinforced concrete column is utilized the production of brick loose tool lamination.Make that operation is numerous and diverse in this way, the cycle is long, and efficient is lower, must etc. after the prefabricated post concrete of lower floor reaches some strength, its upper strata post can be built concrete.Simultaneously, it is larger to take the construction site scope, and the concrete face impression of making is not good enough.

Summary of the invention

In order to solve the deficiencies in the prior art part, the invention provides a kind of Prefabricated reinforced concrete post vertical prefabrication, construct after 90 ° of the traditional prefabricated post upsets.

The present invention is achieved through the following technical solutions: a kind of Prefabricated reinforced concrete post vertical prefabrication, and it may further comprise the steps:

The first step: take steel pipe frame as the bed die bracing frame, the framework that described bed die bracing frame is comprised of cross bar and vertical rod, end template is inserted in bed die bracing frame bottom, and the bracing frame vertical pole ' s span is 120～160mm, establish the bar of sweeping the floor apart from ground 8～12mm place, the cross bar spacing is 700～750mm; At 25mm place, distance ground, establish the first row cross bar; The second row cross bar is located at the 850mm place, and namely the pillar elevation adds the space length of wiping one's face.Bed die adopts steel form, and side template adopts the waterproof bamboo plywood that may reuse;

Second step: cast prefabricated post concrete, wait for 6～10 hours;

The 3rd step: the prefabricated post concrete reaches the later side template of can dismantling of final set, recycling;

The 4th step: the bed die bracing frame reaches after 75% at the pillar concrete strength, and its two end support keeps with middle 3 supports, and all the other all can be pulled down, and turnover is used.

Advantage of the present invention is:

1, changes traditional horizontal prefabrication system, saved the fetal membrane materials such as brick, mortar; Waterproof bamboo plywood as side form can have enough to meet the need use, saves cost, has reduced pollution.

2, reduce the stand-by period, shortened the construction period; The prefabricated post side form adopts the waterproof bamboo plywood, make the surfacing of Prefabricated Concrete post smooth, reach clear water concrete effect.

3, method simple practical, with low cost, be convenient to promote.

Description of drawings

The below is described in further details the present invention with embodiment with reference to the accompanying drawings:

Fig. 1 is structural representation of the present invention;

Fig. 2 is the A-A place profile of Fig. 1.

Among the figure, 1, the bed die bracing frame, 1-1, cross bar, 1-2, vertical rod, 2, side template, 3, end template, 4, the prefabricated post concrete

The specific embodiment

A kind of Prefabricated reinforced concrete post vertical prefabrication, it may further comprise the steps:

The first step: take steel pipe frame as bed die bracing frame 1, the framework that described bed die bracing frame 1 is comprised of cross bar 1-1 and vertical rod 1-2, end template 3 is inserted in bed die bracing frame bottom, and the bracing frame vertical pole ' s span is 150mm, establish the bar of sweeping the floor apart from ground 10mm place, the cross bar spacing is 750mm; At 25mm place, distance ground, establish the first row cross bar; The second row cross bar is located at the 850mm place, and namely the pillar elevation adds the space length of wiping one's face.Bed die adopts steel form, and side template 2 adopts the waterproof bamboo plywood that may reuse;

Second step: cast prefabricated post concrete 4, wait for 6～10 hours;

The 3rd step: the prefabricated post concrete reaches the later side template of can dismantling of final set, recycling;

The 4th step: bed die bracing frame 1 reaches after 75% at the pillar concrete strength, and its two end support keeps with middle 3 supports, and all the other all can be pulled down, and turnover is used.
