Description

Cast-in-place seam template fixing tool

The technical field is as follows:

the utility model relates to a fixed frock of cast-in-place seam template belongs to building prefabricated component installation built-in fitting.

Background art:

the prefabricated building refers to a building assembled on a construction site by using prefabricated components. The building has the advantages of high building speed, less restriction by climatic conditions, labor saving and building quality improvement.

Fabricated buildings have become of interest since the beginning of the 20 th century and have been realized through the sixties. The first attempts made in English, French, Soviet Union, etc. The assembly type building has high construction speed and low production cost, and is rapidly popularized and developed all over the world.

The characteristics of the fabricated building: 1. a large amount of building components, for example side fascia, interior wallboard, superimposed sheet, balcony, air conditioner board, stair, precast beam, prefabricated post etc. are all accomplished by workshop production and processing, and centralized production greatly reduced engineering cost also more does benefit to quality control simultaneously. 2. The building parts produced by the factory are transported to the site for assembly, so that the template engineering and the manual workload are reduced, the construction speed is accelerated, and the method has great significance for reducing the construction cost. 3. The assembly construction changes the whole building from one project to one product. The more standard the component, the higher the production efficiency and the lower the cost, and the performance price of the whole assembly type building is far comparable to that of the traditional construction mode by matching with the digital management of a factory. 4. Unlike traditional building, which has to finish the main body before decoration, the assembled building can complete the decoration of the prefabricated parts before assembling, so as to realize the synchronization between decoration project and main body project, reduce construction process and lower construction cost. 5. The building materials of the fabricated building are selected more flexibly, and various energy-saving and environment-friendly materials such as light steel and wood boards are applied, so that the fabricated building is more consistent with the concept of green buildings.

When the prefabricated component is installed on site, the prefabricated part needs to be connected through the extending steel bars, then a template is erected on the cast-in-place seam, concrete is poured into the erected template, the template and the template need to be pulled together through split bolts in order to prevent the template from expanding, the templates on two sides of the cast-in-place seam of the inner wallboard are fixed through split screws, the method for processing the cast-in-place seam of the outer wallboard comprises the steps that an operator puts up a scaffold on the outer side of the outer wall, an outer template is erected on the outer side of the building, and the outer template and the inner template of the outer wall are pulled together through the split screws.

The existing fixing tool for the external wall panel generally adopts a through-wall split bolt 2 as shown in fig. 2 to fix templates 4 on two sides of the external wall panel 9, the templates 4 are attached to the inner side and the outer side of a gap between two external wall panels 9, a split screw 2 is inserted between the two templates 4, nuts 5 are sleeved on two ends of the split screw 2, and the two templates 5 are fixed; a closed gap is formed between the two templates 5 and the two external wall panels 9 so as to carry out cast-in-place operation; although the cast-in-situ seam template can be fixed by the design, an operator needs to build a scaffold outside the building main body for operation, so that the operation risk is increased, the measure cost is increased, the construction site environment is influenced, and the occupied area of a construction site is increased. The assembly type building has high cost, and the development of the market of the assembly type building is restricted to a certain extent.

The utility model has the following contents:

in order to solve the technical problem, an object of the utility model is to provide a frock is fixed to cast-in-place seam template.

The utility model discloses by following technical scheme implement: the utility model provides a fixed frock of cast-in-place seam template, includes fixed head, counter-pull screw rod, pin, template, nut, counter-pull screw rod one end and fixed head fixed connection, the fixed orifices has been seted up on the fixed head, the opening direction of fixed orifices with counter-pull screw rod length direction is perpendicular, the pin run through in the fixed orifices sets up the nut has been joined in marriage to the screw rod of pulling the spiro union fixed head with between the nut the cover is equipped with the template on the counter-pull screw rod.

Furthermore, a screw hole matched with the oppositely-pulling screw rod is formed in the fixing head, and the oppositely-pulling screw rod is in threaded connection with the fixing head.

Furthermore, a gasket is sleeved on the oppositely-pulling screw rod between the nut and the template.

The utility model has the advantages that: the utility model discloses when using, at first will twist in the screw hole of fixed head to the one end of drawing the screw rod, insert the fixed orifices of fixed head with the pin in the groove that shears of side fascia with the both ends card of pin, pass the template to the other end of drawing the screw rod, the inboard of side fascia is hugged closely to the template, then sheathe gasket in the one end of passing the template to drawing the screw rod to tighten the nut. In the process, the operator completely works inside the building main body, the scaffold is prevented from being built outside, the production safety is guaranteed, the operation risk of the operator is reduced, and the production efficiency is improved.
